WHEREAS, the Board of Directors of the Company, pursuant to Plan Section 15.1 of the Plan, has delegated authority to amend the Plan to

Current Market Value of Common Stock as of the date of contribution.” 
 Section 4.4 is amended by adding the following sentence at
the end thereof:

September 30, 2013 shall be made not later than the due date (including extensions) for filing the Company’s Federal income tax return for that Plan Year, shall be allocated as of September 30, 2013 and shall be based on the Current
Market Value of Common Stock as of the date of contribution.” 

 Section 5.1(c) is hereby amended by the addition of the following sentence at the end
thereof: 
 “Notwithstanding the second sentence hereof, a Participant’s Elective Deferrals for the period commencing April 1,
2013 and ending September 30, 2013 shall be allocated to the Participant’s ESOP Elective Deferral Account as of September 30, 2013 and shall be converted to Common Stock as of a special Valuation Date selected by the ESOP Committee
using the Common Stock value as of such Valuation Date or the value as of March 31, 2013 (whichever is lower).” 

Section 5.1(d) is hereby amended by the addition of the following sentence at the end thereof: 

“Notwithstanding the foregoing, (1) a new or rehired Employee’s Rollover Contribution accepted and received by the ESOP
Committee or Trustee during the period commencing April 1, 2013 and ending September 30, 2013 will be converted to Common Stock based on the Current Market Value as of a special Valuation Date selected by the ESOP Committee or as of
March 31, 2013, whichever is lower; and (2) each other Employee’s Rollover Contribution accepted and received by the ESOP Committee or Trustee during the period commencing April 1, 2013 and ending September 30, 2013 will be

and up to, but excluding, the Revolving Credit Termination Date in an aggregate principal amount at any one 

  
 -24- 

 
time outstanding up to, but not exceeding, the amount of such Lender’s Commitment as then in effect; provided, however, that the sum of the aggregate principal amount of all
such Revolving Credit Loans by all Lenders hereunder, plus the aggregate principal amount of all Swing Line Loans, plus the LC Obligations at any one time outstanding shall not exceed the Aggregate Commitments. Subject to the terms of
this Agreement, during the period from the Closing Date to and up to, but excluding, the Revolving Credit Termination Date, the Borrower may borrow, repay and reborrow the amount described in this Section 2.01(a). 

(b) Letters of Credit. During the period from and including the Closing Date to, but excluding, the date which is five (5) Business
Days prior to the Revolving Credit Termination Date, the Issuing Bank, as issuing bank for the Lenders, agrees to extend credit for the account of the Borrower or any Subsidiary of the Borrower at any time and from time to time by issuing, renewing,
extending or reissuing Letters of Credit; provided, however, the LC Obligations at any one time outstanding shall not exceed the lesser of (i) the LC Commitment or (ii) the Aggregate Commitments, as then in effect, minus the
aggregate principal amount of all Loans then outstanding. The Lenders shall participate in such Letters of Credit according to their respective Percentage Shares. Each of the Letters of Credit shall (i) be issued by the Issuing Bank,
(ii) contain such terms and provisions as are reasonably required by the Issuing Bank, (iii) be for the account of the Borrower or a Subsidiary of the Borrower and (iv) expire not later than the earlier of the date which is one year
after the date of issuance thereof and the date which is five (5) Business Days before the Revolving Credit Termination Date. 
 (c)
Limitation on Types of Loans. Subject to the other terms and provisions of this Agreement, at the option of the Borrower, the Revolving Credit Loans may be Base Rate Loans or LIBOR Loans; provided that, without the prior written consent of
the Majority Lenders, no more than ten (10) LIBOR Loans may be outstanding at any time. 
 (d) Swing Line Loans. 

(i) The Swing Line. Subject to the terms and conditions set forth herein, the Swing Line Lender agrees, in reliance upon
the agreements of the other Lenders set forth in this Section 2.01(d), to make loans (each such loan, a “Swing Line Loan”), to the Borrower from time to time on any Business Day during the period from the Closing Date to
and up to, but excluding, the Revolving Credit Termination Date, in an aggregate amount not to exceed at any time outstanding the amount of the Swing Line Sublimit, notwithstanding the fact that such Swing Line Loans, when aggregated with the
Percentage Share of the outstanding amount of Revolving Credit Loans and LC Obligations of the Lender acting as Swing Line Lender, may exceed the amount of such Lender’s Commitment; provided, however, that after giving effect to
any Swing Line Loan, (A) the sum of the aggregate outstanding amount of the Revolving Credit Loans plus the Swing Line Loans plus LC Obligations shall not exceed the Aggregate Commitments at such time, and (B) the sum of the
aggregate outstanding amount of the Revolving Credit Loans of any Lender (other than the Swing Line Lender) at such time, plus such Lender’s Percentage Share of the outstanding amount of all LC Obligations at such time, plus such
Lender’s Percentage Share of the outstanding amount of all Swing Line Loans at such time shall not exceed such Lender’s Commitment. Within the foregoing limits, and subject to the other terms and conditions hereof, the Borrower may

  
 -25- 

 
borrow under this Section 2.01(d), prepay under Section 2.07, and reborrow under this Section 2.01(d). If the Autoborrow Agreement is in effect, prepayments of Swing Loans shall be
made as provided in the Autoborrow Agreement. Each Swing Line Loan shall bear interest only at a rate based on the Base Rate. Immediately upon the making of a Swing Line Loan, each Lender (other than the Swing Line Lender) shall be deemed to, and
hereby irrevocably and unconditionally agrees to, purchase from the Swing Line Lender a risk participation in such Swing Line Loan in an amount equal to the product of such Lender’s Percentage Share times the amount of such Swing Line
Loan. 
 (ii) Calculation of Availability. Without in any way modifying the provisions of the foregoing
clause (i), it is hereby agreed that the Administrative Agent shall endeavor to give notice to the Swing Line Lender at any time that the unutilized portion of the Aggregate Commitments is less than the Swing Line Sublimit and to specify in
such notice the unutilized portion of the Aggregate Commitments at such time. The Administrative Agent shall endeavor to provide such notice on the same Business Day as making a Loan that reduces availability below the Swing Line Sublimit. This
clause (ii) shall not (a) give rise to any liability on behalf of the Administrative Agent, and on any date that a Swing Line Loan is requested, the Swing Line Lender may request confirmation of the unutilized portion of the Aggregate
Commitments (but failure of the Administrative Agent to respond to such request shall not relieve the Swing Line Lender of its obligations to make Swing Line Loans hereunder) or (b) imply that the Administrative Agent has any obligation to
calculate the outstanding Swing Line Loans (it being understood that the Swing Line Lender shall keep a record of the principal amount of the Swing Line Loans outstanding). 

(iii) Borrowing Procedures. Each Swing Line Borrowing shall be made upon the Borrower’s irrevocable notice to the
Swing Line Lender, which notice shall be in the form of a Swing Line Loan Notice delivered by e-mail, scanned PDF or any other electronic delivery specified by the Swing Line Lender. Each such Swing Line Loan Notice must be received by the Swing
Line Lender not later than 3:00 p.m., Houston, Texas time on a Business Day, and shall specify (A) the amount to be borrowed, which shall be a minimum of $200,000 or any whole multiple of $50,000 in excess thereof (except as otherwise
agreed in the Autoborrow Agreement, if applicable), and (B) the requested borrowing date, which shall be a Business Day. If an Autoborrow Agreement is in effect, Swing Line Loans shall be made in the amount and at the times provided in such
Autoborrow Agreement, and Borrower shall not be required to deliver a Swing Line Loan Notice in respect of the Swing Line Loans extended pursuant to such Autoborrow Agreement. Promptly after receipt by the Swing Line Lender of a Swing Line Loan
Notice from the Borrower and promptly upon entry into an Autoborrow Agreement, the Swing Line Lender shall provide a copy of such Swing Line Loan Notice or Autoborrow Agreement to the Administrative Agent. Subject to the terms and conditions hereof,
the Swing Line Lender will, not later than 5:00 p.m., Houston, Texas time on the borrowing date specified in such Swing Line Loan Notice (or in the Autoborrow Agreement, if applicable), make a Swing Line Loan in the amount specified in the
Swing Line Loan Notice available to the Borrower at its office by crediting the account of the Borrower on the books of the Swing Line Lender in immediately available funds; provided that to the extent the Swing Line Lender has received notice from
the Administrative Agent that the 

  
 -26- 

 
unutilized portion of the Aggregate Commitments is less than the Swing Line Sublimit (as described in clause (ii) above), the Swing Line Lender may reduce the amount of the Swing Line Loan
as necessary to ensure that the Loans (together with outstanding Letters of Credit) do not exceed the Aggregate Commitments. 

(iv) Conditions. Delivery by the Borrower of a Swing Line Loan Notice shall constitute a representation and warranty by
the Borrower and, on each day that a Swing Line Loan is made under an Autoborrow Agreement, the Borrower shall be deemed to represent and warrant that (a) the amount of the Swing Line Loan requested in such Swing Line Loan Notice or to be made
pursuant to the Autoborrow Agreement is available for borrowing hereunder and (b) no Event of Default has occurred and is continuing. Upon obtaining knowledge that one or more of the conditions specified in Section 6.02 is not then
satisfied, the Administrative Agent shall inform the Swing Line Lender of the condition that is unsatisfied. 
 (v)
Refinancing of Swing Line Loans. On each Swing Line Settlement Date and at any other time the Swing Line Lender, in its sole and absolute discretion, may request, the Swing Line Lender, on behalf of the Borrower (which hereby irrevocably
authorizes the Swing Line Lender to so request on its behalf), may require that each Lender make a Revolving Credit Loan (which shall be a Base Rate Loan) in an amount equal to such Lender’s Percentage Share of the amount of Swing Line Loans
then outstanding. Such request shall be made in writing (which written request shall be deemed to be a borrowing notice delivered pursuant to Section 2.02(c) for purposes hereof) and in accordance with the requirements of Section 2.02,
without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion of the Aggregate Commitments. The Swing Line Lender shall furnish the Borrower with a copy of the
applicable borrowing notice promptly after delivering such notice to the Administrative Agent not later than noon Houston time on a Business Day. Each Lender shall make an amount equal to its Percentage Share of the amount specified in such
notice available to the Administrative Agent in immediately available funds for the account of the Swing Line Lender at the Administrative Agent’s Principal Office not later than 2:00 p.m. Houston, Texas time on the day specified in such
borrowing notice, whereupon, subject to Section 2.01(d)(v)(B), each Lender that so makes funds available shall be deemed to have made a Base Rate Loan to the Borrower in such amount. The Administrative Agent shall remit the funds so received to
the Swing Line Lender. 
 (A) If for any reason any Swing Line Loan cannot be refinanced by such a Revolving Credit Loan in
accordance with Section 2.01(d)(v), the request for Revolving Credit Loans submitted by the Swing Line Lender as set forth herein shall be deemed to be a request by the Swing Line Lender that each of the Lenders fund its risk participation in
the relevant Swing Line Loan and each Lender’s payment to the Administrative Agent for the account of the Swing Line Lender pursuant to Section 2.01(d)(v) shall be deemed payment in respect of such participation. 

  
 -27- 

 (B) If any Lender fails to make available to the Administrative Agent for the
account of the Swing Line Lender any amount required to be paid by such Lender pursuant to the foregoing provisions of this Section 2.01(d)(v) by the time specified herein, the Swing Line Lender shall be entitled to recover from such Lender
(acting through the Administrative Agent), on demand, such amount with interest thereon for the period from the date such payment is required to the date on which such payment is immediately available to the Swing Line Lender at a rate per annum
equal to the greater of the Federal Funds Rate and a rate determined by the Swing Line Lender in accordance with banking industry rules on interbank compensation, plus any administrative, processing or similar fees customarily charged by the Swing
Line Lender in connection with the foregoing. If such Lender pays such amount (with interest and fees as aforesaid), the amount so paid shall constitute such Lender’s Revolving Credit Loan included in the relevant borrowing or funded
participation in the relevant Swing Line Loan, as the case may be. A certificate of the Swing Line Lender submitted to any Lender (through the Administrative Agent) with respect to any amounts owing under this clause (B) shall be conclusive
absent manifest error. 
 (C) Each Lender’s obligation to make Revolving Credit Loans or to purchase and fund risk
participations in Swing Line Loans pursuant to this Section 2.01(d)(v) shall be absolute and unconditional and shall not be affected by any circumstance, including (A) any setoff, counterclaim, recoupment, defense or other right which such
Lender may have against the Swing Line Lender, the Borrower or any other Person for any reason whatsoever, (B) the occurrence or continuance of a Default, or (C) any other occurrence, event or condition, whether or not similar to any of
the foregoing; provided, however, that each Lender’s obligation to make Revolving Credit Loans pursuant to this Section 2.01(d)(v) is subject to the conditions set forth in Section 6.02. No such funding of risk
participations shall relieve or otherwise impair the obligation of the Borrower to repay Swing Line Loans, together with interest as provided herein. 

(vi) Repayment of Participations. (A) At any time after any Lender has purchased and funded a risk participation in
a Swing Line Loan, if the Swing Line Lender receives any payment on account of such Swing Line Loan, the Swing Line Lender will distribute to such Lender its Percentage Share thereof in the same funds as those received by the Swing Line Lender. 

(B) If any payment received by the Swing Line Lender in respect of principal or interest on any Swing Line Loan is required to
be refunded by the Swing Line Lender under any of the circumstances described in Section 12.10 (including pursuant to any settlement entered into by the Swing Line Lender in its discretion), each Lender shall pay to the Swing Line Lender its
Percentage Share thereof on demand of the Administrative Agent, plus interest thereon from the date of such demand to the date such amount is returned, at a rate per annum equal to the Federal Funds Rate. The Administrative Agent will make
such demand upon the request of the Swing Line Lender. The obligations of the Lenders under this clause shall survive the payment in full of the Obligations and the termination of this Agreement. 

  
 -28- 

 (vii) Interest for Account of Swing Line Lender. The Swing Line Lender
shall be responsible for invoicing the Borrower for interest on the Swing Line Loans. Until each Lender funds it Revolving Credit Loan or risk participation pursuant to this Section 2.01(d) to refinance such Lender’s Percentage Share of
any Swing Line Loan, interest in respect of such Percentage Share shall be solely for the account of the Swing Line Lender. 

(viii) Payments Directly to Swing Line Lender. The Borrower shall make all payments of principal and interest in respect
of the Swing Line Loans directly to the Swing Line Lender. 
 (ix) Alternative Swing Line Procedures. Notwithstanding
the foregoing, the Borrower and the Swing Line Lender may alter or vary any of the timing for notices of or the form of notice required for Swing Line Borrowings or repayment of Swing Line Loans, the minimum amounts for Swing Line Borrowings or
repayment of Swing Line Loans, and/or any of the other borrowing procedures for the Swing Line (collectively referred to as “Alternative Swing Line Procedures”) from those set forth in this Section 2.01(d) pursuant to
any Autoborrow Agreement, Cash Management Agreement or other agreement entered into between Borrower and the Swing Line Lender and in effect from time to time. 

(e) Participations. By the issuance of a Letter of Credit (or an amendment to an existing Letter of Credit increasing
the amount thereof) and without any further action on the part of the Issuing Bank, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in such Letter of Credit equal to such
Lender’s Percentage Share of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and unconditionally agrees to pay to the Administrative
Agent, for the account of the Issuing Bank, such Lender’s Percentage Share of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.01(f) (but giving effect to the proviso
in the first sentence thereof), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.01(e) in
respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or
termination of the Aggregate Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 

(f) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower
shall reimburse such LC Disbursement by paying the Issuing Bank, an amount equal to such LC Disbursement (i) not later than 2:00 p.m., Houston, Texas time, on the date such LC Disbursement is made, if the Borrower shall have received
notice of such LC Disbursement prior to 12:00 noon, Houston Texas time, on such date or 

  
 -29- 

 
(ii) not later than 12:00 noon, Houston, Texas time, on the first Business Day immediately following the day that the Borrower received such notice, if such notice in not received prior
to 12:00 noon on the date such LC Disbursement was made. If the Borrower fails to make such payment when due, the Issuing Bank shall notify the Administrative Agent and the Administrative Agent shall notify each Lender of the applicable LC
Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Percentage Share thereof. Such notice shall be made in writing (which written request shall be deemed to be a borrowing notice delivered pursuant to
Section 2.02(c) for purposes hereof) and in accordance with the requirements of Section 2.02, without regard to the minimum and multiples specified therein for the principal amount of Base Rate Loans, but subject to the unutilized portion
of the Aggregate Commitments and the conditions set forth in Section 6.02. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Percentage Share of the payment then due from the Borrower and the
Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. The Administrative Agent shall remit the funds so received to the Issuing Bank. Promptly following receipt by the Administrative Agent of any
payment from the Borrower pursuant to this Section 2.01(f), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.01(f) to reimburse the
Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.01(f) to reimburse the Issuing Bank for any LC Disbursement shall constitute a Base Rate Loan to the
Borrower in such amount. Any payment made by a Lender pursuant to this Section 2.01(f) to reimburse the Issuing Bank for any LC Disbursement shall not relieve or otherwise impair the obligation of the Borrower to repay such Base Rate Loans,
together with interest as provided herein. 
 (g) Obligations Absolute. The Borrower’s obligation to reimburse LC
Disbursements as provided in Section 2.01(f) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of
(i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Application or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be
forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit or any Letter of Credit Application, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.01(g),
constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Affiliates shall have any liability
or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any
error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in
interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any
direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by 

  
 -30- 

 
the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other
documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of
competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents
presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole reasonable discretion, either accept and make payment upon such documents without responsibility for further
investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit. 

(h) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to
represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether such Issuing Bank has made or will
make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement. 

(i) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the Borrower shall have reimbursed the Issuing
Bank for such LC Disbursement, the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum
then applicable to Base Rate Loans. Interest accrued pursuant to this Section 2.01(i) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.01(f) to
reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment. 
 (j) Cash Collateralization. If
(i) any Event of Default shall occur and be continuing and the Borrower receive notice from the Administrative Agent, the Issuing Bank or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.01(j), or
(ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 2.07, then the Borrower shall deposit, in an account with the Administrative
Agent, in the name of the Administrative Agent and for the benefit of the Issuing Bank and the Lenders, an amount in cash equal to, in the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 2.07, the
amount of such excess as provided in Section 2.07, as of such date, plus any accrued and unpaid interest thereon to the extent not otherwise included in such payment; provided that the obligation to deposit such cash collateral shall
become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect to the Borrower or any Guarantor described in
Section 10.01(e), (f) or (g). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first priority and continuing perfected security interest in and Lien on such account
and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire 

  
 -31- 

 
transfers made thereto, any and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other property from time to time
received, receivable or otherwise payable in respect of, or in exchange for, any or all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The
Borrower’s obligation to deposit amounts pursuant to this Section 2.01(j) shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such
amount under the terms of a Letter of Credit, and, to the fullest extent permitted by applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Borrower or any of its Subsidiaries
may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the
Borrower’s Obligations under this Agreement and the other Loan Documents in a “securities account” (within the meaning of Article 8 of the UCC) over which the Administrative Agent shall have “control” (within the
meaning of the UCC). Notwithstanding the foregoing, the Borrower may direct the Administrative Agent and the “securities intermediary” (within the meaning of the UCC) to invest amounts credited to the securities account, at the
Borrower’s risk and expense, in Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse, on a pro rata basis, the Issuing Bank for LC
Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been
accelerated, be applied to satisfy other obligations of the Borrower under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of
Default, and the Borrower is not otherwise required to pay to the Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 2.07, then such amount (to the extent not applied as
aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived. 

Section 2.02 Borrowings, Continuations and Conversions, Letters of Credit. 

(a) Borrowings. The Borrower shall give the Administrative Agent (which shall promptly notify the Lenders) advance notice as hereinafter
provided of each borrowing hereunder, which shall specify (i) the aggregate amount of such borrowing, (ii) the Type and (iii) the date (which shall be a Business Day) of the Loans to be borrowed, and (iv) (in the case of LIBOR
Loans) the duration of the Interest Period therefor. 
 (b) Minimum Amounts. All borrowings of Loans that are Base Rate Loans shall be
in amounts of at least $1,000,000.00 or the remaining balance of the Aggregate Commitments, if less, or any whole multiple of $100,000.00 in excess thereof, and all borrowings of Loans that are LIBOR Loans shall be in amounts of at least
$2,000,000.00 or any whole multiple of $500,000.00 in excess thereof. 
 (c) Notices. All borrowings, continuations and conversions of
Loans shall require advance written notice to the Administrative Agent (which shall promptly notify the Lenders) in the form of Exhibit B (or telephonic notice promptly confirmed by such a written

  
 -32- 

 
notice), which in each case shall be irrevocable, from the Borrower to be received by the Administrative Agent not later than 11:00 a.m., Houston, Texas time at least one Business Day prior
to the date of each borrowing of Loans that are Base Rate Loans and three Business Days prior to the date of each borrowing of Loans that are LIBOR Loans, continuation or conversion. Without in any way limiting the Borrower’s obligation to
confirm in writing any telephonic notice, the Administrative Agent may act without liability upon the basis of telephonic notice believed by the Administrative Agent in good faith to be from the Borrower prior to receipt of written confirmation. In
each such case, the Borrower hereby waives the right to dispute the Administrative Agent’s record of the terms of such telephonic notice except in the case of gross negligence or willful misconduct by the Administrative Agent. 

(d) Continuation Options. Subject to the provisions made in this Section 2.02(d), the Borrower may elect to continue all or any
part of any LIBOR Loan beyond the expiration of the then current Interest Period relating thereto by giving advance notice as provided in Section 2.02(c) to the Administrative Agent (which shall promptly notify the Lenders) of such election,
specifying the amount of such Loan to be continued and the Interest Period therefor. In the absence of such a timely and proper election, the Borrower shall be deemed to have elected to convert such LIBOR Loan to a Base Rate Loan pursuant to
Section 2.02(e). All or any part of any LIBOR Loan may be continued as provided herein, provided that (i) any continuation of any such Loan shall be (as to each Loan as continued for an applicable Interest Period) in amounts of at
least $2,000,000.00 or any whole multiple of $500,000.00 in excess thereof and (ii) no Default shall have occurred and be continuing. If an Event of Default shall have occurred and be continuing, each LIBOR Loan shall be converted to a Base
Rate Loan on the last day of the Interest Period applicable thereto. 
 (e) Conversion Options. The Borrower may elect to convert all
or any part of any LIBOR Loan on the last day of the then current Interest Period relating thereto to a Base Rate Loan by giving advance notice to the Administrative Agent (which shall promptly notify the Lenders) of such election. Subject to the
provisions made in this Section 2.02(e), the Borrower may elect to convert all or any part of any Base Rate Loan at any time and from time to time to a LIBOR Loan by giving advance notice as provided in Section 2.02(c) to the
Administrative Agent (which shall promptly notify the Lenders) of such election. All or any part of any outstanding Loan may be converted as provided herein, provided that (i) any conversion of any Base Rate Loan into a LIBOR Loan shall
be (as to each such Loan into which there is a conversion for an applicable Interest Period) in amounts of at least $2,000,000.00 or any whole multiple of $500,000.00 in excess thereof and (ii) no Default shall have occurred and be continuing.
If an Event of Default shall have occurred and be continuing, no Base Rate Loan may be converted into a LIBOR Loan. 
 (f) Advances.
Not later than 11:00 a.m., Houston, Texas time on the date specified for each borrowing of Loans hereunder, each Lender shall make available the amount of the Loan to be made by it on such date to the Administrative Agent, to an account which
the Administrative Agent shall specify, in immediately available funds, for the account of the Borrower. The amounts so received by the Administrative Agent shall, subject to the terms and conditions of this Agreement, be made available to the
Borrower by depositing the same, in immediately available funds, in an account of the Borrower, designated by the Borrower. 

  
 -33- 

 (g) Letters of Credit. The Borrower shall give the Issuing Bank with a copy to the
Administrative Agent (who shall promptly notify the Lenders of such request and their Percentage Share of such Letter of Credit), a Letter of Credit Application to be received by the Issuing Bank not later than 11:00 a.m., Houston, Texas time
not less than three (3) Business Days prior thereto of each request for the issuance renewal or extension, of a Letter of Credit hereunder which request shall specify (i) the amount of such Letter of Credit, (ii) the date (which shall
be a Business Day) such Letter of Credit is to be issued, renewed or extended, (iii) the duration thereof, (iv) the name and address of the beneficiary thereof, (v) the form and type of the Letter of Credit and (vi) such other
information as the Issuing Bank may reasonably request, all of which shall be reasonably satisfactory to the Issuing Bank. Subject to the terms and conditions of this Agreement, on the date specified for the issuance, renewal or extension of a
Letter of Credit, the Issuing Bank shall issue, renew or extend such Letter of Credit to the beneficiary thereof. 
 In conjunction with the
issuance of each Letter of Credit, the Borrower and the Subsidiary, if the account party, shall execute a Letter of Credit Agreement. In the event of any conflict between any provision of a Letter of Credit Agreement and this Agreement, the
Borrower, the Issuing Bank, the Administrative Agent and the Lenders hereby agree that the provisions of this Agreement shall govern. 
 The
Issuing Bank will send to the Borrower and to the Administrative Agent, promptly upon issuance of any Letter of Credit, or an amendment thereto, a true and complete copy of such Letter of Credit, or such amendment thereto. 

Section 2.03 Changes of Commitments. (a) The Aggregate Commitments shall at all times be equal to the lesser of (i) the
Aggregate Maximum Revolving Credit Amounts after adjustments resulting from reductions pursuant to Section 2.03(b) or (ii) the Borrowing Base as determined from time to time. 

(b) The Borrower shall have the right to terminate or to reduce the amount of the Aggregate Maximum Revolving Credit Amounts or the Swing Line
Sublimit at any time, or from time to time, upon not less than three (3) Business Days’ prior notice to the Administrative Agent (which shall promptly notify the Lenders) of each such termination or reduction, which notice shall specify
the effective date thereof and the amount of any such reduction (which shall not be less than (i) $5,000,000.00 or any whole multiple of $1,000,000.00 in excess thereof for any reduction of the Aggregate Maximum Revolving Credit Amounts, and
(ii) $1,000,000 or any whole multiple of $500,000 in excess thereof for the Swing Line Sublimit) and shall be irrevocable and effective only upon receipt by the Administrative Agent; provided that a notice of termination or reduction of
the Aggregate Maximum Credit Amounts delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, the incurrence of other Debt or the disposition of certain assets, in which case such notice
may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. 

(c) The Aggregate Maximum Revolving Credit Amounts and the Swing Line Sublimit once terminated or reduced may not be reinstated.

 Section 2.04 Fees. 

(a) Commitment Fee. The Borrower shall pay to the Administrative Agent for the account of each Lender in accordance with its Percentage
Share a Commitment fee on the daily average unused amount of the Borrowing Base for the period from and including the Closing Date up to, but excluding, the Revolving Credit Termination Date in an amount equal to (i) the actual daily amount by
which the Aggregate Commitments exceed the sum of the outstanding principal amount of Loans plus the outstanding amount of LC Obligations, multiplied by (ii) a rate per annum equal to the amount reflected on the appropriate intersection in the
table set forth in the definition of “Applicable Margin.” Accrued Commitment fees shall be payable quarterly in arrears on each Quarterly Date and on the Revolving Credit Termination Date. For the avoidance of doubt, the outstanding
principal amount of any Swing Line Loans shall not be included as usage in calculating any Commitment fees due under this Section 2.04(a). 

(b) Letter of Credit Fees. The Borrower agrees to pay the Administrative Agent, for the account of each Lender, commissions for issuing
the Letters of Credit on the daily average outstanding of the maximum liability of the Issuing Bank existing from time to time under such Letter of Credit (calculated separately for each Letter of Credit) at the Applicable Margin for LIBOR Loans
determined on the date of issuance of the applicable Letter of Credit. Each Letter of Credit shall be deemed to be outstanding up to the full face amount of the Letter of Credit until the Issuing Bank has received the canceled Letter of Credit or a
written cancellation of the Letter of Credit from the beneficiary of such Letter of Credit in form and substance acceptable to the Issuing Bank, or for any reductions in the amount of the Letter of Credit (other than from a drawing), written
notification from the beneficiary of such Letter of Credit. Such commissions are payable in advance at issuance of the Letter of Credit for the first year thereof and thereafter, quarterly in arrears on each Quarterly Date and upon cancellation or
expiration of each such Letter of Credit. 
 (i) The Borrower shall pay to the Issuing Bank, for its own account, a fronting
fee equal to the greater of: (x) .175% per annum of the Letter of Credit, and (y) $500.00. 
 (ii) Upon each
amendment, transfer, or negotiation of any Letter of Credit, the Borrower shall pay the Issuing Bank, for its own account, such fees that are in accordance with such Issuing Bank’s then-current fee policy. 

(c) Other Fees. The Borrower shall pay to the Administrative Agent for its account such other fees as are set forth in the fee letter
from the Lender to the Borrower on the dates specified therein to the extent not paid prior to the Closing Date. 
 Section 2.05
Several Obligations. The failure of any Lender to make any Loan to be made by it or to provide funds for disbursements or reimbursements under Letters of Credit or for its participations in Swing Line Loans on the date specified therefor
shall not relieve any other Lender of its obligation to make its Loan or provide funds on such date, but no Lender shall be responsible for the failure of any other Lender to make a Loan to be made by such other Lender or to provide funds to be
provided by such other Lender. 

  
 -35- 

 Section 2.06 Notes. If requested by a Lender, the Loans made by such Lender may be
evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated the Closing Date, payable to such Lender in a principal amount equal to its Maximum Revolving Credit Amount as originally in effect and
otherwise duly completed and such substitute Notes as required by Section 12.06(b). The date, amount, Type, interest rate and Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be
recorded by such Lender on its books for its Note, and on the schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any such notation or to attach a schedule shall not affect
any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note. If requested by the Swing Line Lender, Swing Line Loans shall be evidenced by a single
promissory note (the “Swing Line Note”) of the Borrower dated (i) the Closing Date or (ii) the effective date of an appointment of a successor Swing Line Lender pursuant to Section 11.09, payable to the Swing
Line Lender in a principal amount equal to the Swing Line Sublimit as originally in effect and containing such other terms and provisions as shall be satisfactory to the Swing Line Lender. The date, amount and interest rate of each Swing Line Loan
made by the Swing Line Lender, and all payments made on account of the principal thereof, shall be recorded by the Swing Line Lender on its books for its Swing Line Note and on the schedule attached to such Swing Line Note or any continuation
thereof or on any separate record maintained by the Swing Line Lender. Failure to make any such notation or to attach a schedule shall not affect the Swing Line Lender’s or the Borrower’s rights or obligations in respect of such Swing Line
Loans or affect the validity of the transfer by the Swing Line Lender of its Swing Line Note. 
 Section 2.07 Prepayments. 

(a) Voluntary Prepayments. (i) The Borrower may prepay the Loans that are Base Rate Loans with prior written notice to the
Administrative Agent (which shall promptly notify the Lenders) received not later than 10:00 a.m., Houston, Texas time on the date of such prepayment, which notice shall specify the prepayment date (which shall be a Business Day) and the amount
of the prepayment (which shall be at least $500,000.00 and a multiple of $100,000.00 or the remaining aggregate principal balance outstanding on the Loans) and shall be irrevocable and effective only upon receipt by the Administrative Agent,
provided that interest on the principal prepaid, accrued to the prepayment date, shall be paid on the prepayment date. The Borrower may prepay Loans that are LIBOR Loans on the same conditions as for Loans that are Base Rate Loans (except
that prior notice to the Administrative Agent shall be not less than three (3) Business Days for LIBOR Loans) and in addition such prepayments of LIBOR Loans shall be subject to the terms of Section 5.05 and shall be in an amount equal to
all of the LIBOR Loans for the Interest Period prepaid. 
 (ii) The Borrower may, upon notice to the Swing Line Lender (with
a copy to the Administrative Agent), at any time or from time to time, voluntarily prepay Swing Line Loans in whole or in part without premium or penalty; provided, however, that (A) such notice must be received by the Swing Line
Lender and the Administrative Agent not later than 3:00 p.m., Houston, Texas time on the date of the prepayment, and (B) any such prepayment shall be in a minimum principal amount of $200,000. Each such notice shall specify the date and
amount of such prepayment. If such notice is given by the 

  
 -36- 

 
Borrower, the Borrower shall make such prepayment and the payment amount specified in such notice shall be due and payable on the date specified therein. Notwithstanding the foregoing, the
Borrower and the Swing Line Lender may separately agree to vary such voluntary prepayment procedures pursuant to any Alternative Swing Line Procedures that may be in effect from time to time. 

(b) Mandatory Prepayments. (i) If, after giving effect to any termination or reduction of the Aggregate Maximum Revolving Credit
Amounts pursuant to Section 2.03(b), the sum of the outstanding aggregate principal amount of the Revolving Credit Loans, plus the outstanding aggregate principal amount of the Swing Line Loans, plus the LC Obligations exceeds the
Aggregate Maximum Revolving Credit Amounts, the Borrower shall (i) prepay the Revolving Credit Loans and the Swing Line Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with
interest on the principal amount paid accrued to the date of such prepayment and (ii) if any excess remains after prepaying all of the Revolving Credit Loans and the Swing Line Loans because of LC Obligations, pay to the Administrative Agent on
behalf of the Lenders an amount equal to the excess to be held as cash collateral as provided in Section 2.01(j) hereof. If, after giving effect to any termination or reduction of the Swing Line Sublimit pursuant to Section 2.03(b), the
outstanding principal amount of the Swing Line Loans exceeds the Swing Line Sublimit, the Borrower shall prepay the Swing Line Loans on the date of such termination or reduction in an aggregate principal amount equal to the excess, together with
interest on the principal amount paid accrued to the date of such prepayment. 
 (ii) Upon any redetermination or reduction
of the amount of the Borrowing Base in accordance with Section 2.08(b) or (c) or an adjustment under Section 8.07(c), if the redetermined or adjusted Borrowing Base is less than the sum of the aggregate outstanding principal amount of
the Revolving Credit Loans, plus the aggregate principal amount of the outstanding Swing Line Loans, plus the LC Obligations (a “Deficiency”), then the Borrower shall within thirty (30) days of such
Borrowing Base redetermination do one or any combination of the following: (i) prepay the Loans in an aggregate principal amount equal to such excess, together with interest on the principal amount paid accrued to the date of such prepayment,
(ii) notify the Administrative Agent that Borrower will prepay, in five (5) equal monthly installments commencing on the date of such notice and continuing on the same day the next four months (unless there is no corresponding day, in
which event, it will be paid on the last day of such month), the Loans in an aggregate principal amount equal to such excess, together with interest on the principal amount paid accrued to the date of such prepayment; and/or (iii) provide
additional collateral acceptable to the Administrative Agent on Oil and Gas Properties or other assets sufficient to increase the Borrowing Base to an amount at least equal to the aggregate outstanding principal amounts of the Loans (and in
connection therewith provide to the Administrative Agent such Engineering Reports as the Administrative Agent may reasonably request), and if a Deficiency remains after prepaying all of the Revolving Credit Loans and Swing Line Loans because of LC
Obligations, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such Deficiency to be held as cash collateral as provided in Section 2.01(j). 

  
 -37- 

 (iii) If, as a result of any reduction of the Borrowing Base for any reason
(including as a result of a disposition of Oil and Gas Properties, the issuance of Debt or the termination of transactions under Hedge Agreements) other than as a result of the redetermination of the Borrowing Base pursuant to Section 2.08(b)
or (c), a Deficiency shall exist, then the Borrower shall promptly, and in any event within two (2) Business Days prepay the Loans in an aggregate principal amount equal to such excess, together with interest on such principal amount to the
date of such prepayment, and if a Deficiency remains after prepaying all of the Loans because of LC Obligations, the Borrower shall pay to the Administrative Agent on behalf of the Lenders an amount equal to such Deficiency to be held as cash
collateral as provided in Section 2.01(j). 
 (c) Generally. Prepayments permitted or required under this Section 2.07 shall
be without premium or penalty, except as required under Section 5.05 for prepayment of LIBOR Loans. Any prepayments on the Revolving Credit Loans and Swing Line Loans may be reborrowed subject to the then effective Aggregate Commitments and the
other terms and conditions of this Agreement. 
 Section 2.08 Borrowing Base. (a) The Borrowing Base shall be determined in
accordance with Section 2.08(b) by the Administrative Agent and the Lenders and is subject to redetermination in accordance with Section 2.08(c). Upon any redetermination of the Borrowing Base, such redetermination shall remain in effect
until the next successive Redetermination Date unless otherwise adjusted as contemplated by Section 2.08(e), Section 2.08(f), Section 8.07(c) or Section 9.14. So long as any of the Commitments are in effect or any LC Exposure or
Loans are outstanding hereunder, this facility shall be governed by the then effective Borrowing Base. During the period from and after the Closing Date, until the first redetermination pursuant to Section 2.08(c) or adjustment pursuant to
Section 2.08(e), Section 2.08(f), Section 8.07(c) or Section 9.14, the amount of the Borrowing Base shall be $275,000,000.00. 

(b) Within twenty (20) days following its receipt of the reports required by Section 8.06 and such other reports, data and
supplemental information as may from time to time be reasonably requested by the Administrative Agent (the “Engineering Reports”), the Administrative Agent will propose to the Lenders a Borrowing Base, in its sole discretion
and in accordance with its normal and customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. Following receipt of such proposal, Lenders holding 100% of the Aggregate Commitments must
approve any increase to the Borrowing Base and the Required Lenders must approve a decrease in, or maintenance of, the Borrowing Base, which approvals shall be made by each Lender, in its sole discretion and in accordance with its normal and
customary procedures for evaluating oil and gas reserves and other related assets as such exist at that particular time. After having received notice of such proposal by the Administrative Agent, all of the Lenders shall have fifteen (15) days
to agree or disagree with such proposal. If at the end of the fifteen (15) days, any Lender shall have not communicated its approval or disapproval, such silence shall be deemed to be an approval of the Administrative Agent’s proposal, and
the Administrative Agent’s proposal shall be the new Borrowing Base. If however, within the time prescribed by the preceding sentence, (i) all the Lenders have not approved (or have not been deemed to have approved) the Administrative
Agent’s proposal with respect to an increase in the Borrowing Base, or (ii) the Required Lenders have not approved (or have not been deemed to have approved) the Administrative Agent’s

  
 -38- 

 
proposal with respect to a decrease in, or maintenance of, the Borrowing Base, the Administrative Agent shall poll the Lenders to ascertain the highest Borrowing Base amount and highest amount
approved by either all the Lenders (with respect to an increase in the Borrowing Base) or the Required Lenders (with respect to a decrease in, or maintenance of, the Borrowing Base) shall become the new Borrowing Base. 

(c) So long as any of the Commitments are in effect and until payment in full of all Loans and satisfaction of the LC Obligations hereunder, on
or around the first Business Day of each November and May, commencing May 1, 2014 (each being a “Scheduled Redetermination Date”), the Lenders shall redetermine the amount of the Borrowing Base in accordance with
Section 2.08(b). In addition, (i) the Borrower may initiate a redetermination of the Borrowing Base at any other time as it so elects by specifying in writing to the Administrative Agent (who will promptly notify the Lenders) the date by
which the Borrower will furnish to the Administrative Agent and the Lenders a Reserve Report in accordance with Section 8.06(b) and the date by which such redetermination is requested to occur; provided, however, that the Borrower
may initiate only one such unscheduled redetermination between Scheduled Redetermination Dates and (ii) the Administrative Agent may initiate a redetermination of the Borrowing Base at any other time as it so elects by specifying in writing to
the Borrower the date by which the Borrower is to furnish a Reserve Report in accordance with Section 8.06(b) and the date on which such redetermination is to occur; provided, however, that the Administrative Agent may initiate
only one such unscheduled redetermination between Scheduled Redetermination Dates. 
 (d) The Administrative Agent shall promptly notify in
writing the Borrower and the Lenders of the new Borrowing Base. Any redetermination of the Borrowing Base shall not be in effect until written notice is given to the Borrower. 

(e) Notwithstanding anything to the contrary contained herein, each time the Borrower issues any Senior Unsecured Notes, then on the date of
issuance thereof, the Borrowing Base then in effect shall be reduced automatically by an amount equal to twenty-five percent (25%) of the stated principal amount of such Senior Unsecured Notes so issued; provided that notwithstanding the
foregoing, with respect to any such Debt issued on or before the date of the first redetermination of the Borrowing Base pursuant to this Agreement, the Borrowing Base shall only be reduced by the amount of such Debt issued in excess of
$150,000,000.00. The Borrowing Base as so reduced shall become the new Borrowing Base immediately upon such date of issuance and shall remain in effect until redetermined pursuant to this Agreement. For purposes of this Section 2.08(e), if any
Senior Unsecured Notes are is issued at a discount or otherwise sold for less than “par”, the reduction shall be calculated based upon the stated principal amount without reference to such discount. Such automatic redetermination of the
Borrowing Base shall not constitute a ‘special redetermination’ under Section 2.08(c)(ii) of the Credit Agreement. 
 (f) In
the event that the Borrower shall notify the Administrative Agent of the assignment, termination or unwinding of any Hedge Agreement as provided in Section 8.01(i), the Administrative Agent shall have the right to adjust the Borrowing Base to
reflect the economic effect of such assignment, termination or unwinding on the Borrowing Base. 

  
 -39- 

 Section 2.09 Assumption of Risks. The Borrower assumes all risks of the acts or
omissions of any beneficiary of any Letter of Credit or any transferee thereof with respect to its use of such Letter of Credit. Neither the Issuing Bank, the Administrative Agent nor any Lender shall be responsible for any error, neglect, or
default of any of the Issuing Bank’s correspondents; and none of the above shall affect, impair or prevent the vesting of any of the Issuing Bank’s, the Administrative Agent’s or any Lender’s rights or powers hereunder or under
the Letter of Credit Agreements, all of which rights shall be cumulative. The Issuing Bank and its correspondents may accept certificates or other documents that appear on their face to be in order, without responsibility for further investigation
of any matter contained therein regardless of any notice or information to the contrary. In furtherance and not in limitation of the foregoing provisions, the Borrower agrees that any action, inaction or omission taken or not taken by the Issuing
Bank or by any correspondent for the Issuing Bank in good faith in connection with any Letter of Credit, or any related drafts, certificates, documents or instruments, shall be binding on the Borrower and shall not put the Issuing Bank or its
correspondents under any resulting liability to the Borrower. 
 Section 2.10 Lending Offices. The Loans of each Type made by
each Lender shall be made and maintained at such Lender’s Applicable Lending Office for Loans of such Type.

 -41- 

 
Administrative Agent of any principal of or interest on any borrowing, the Borrower shall notify the Administrative Agent of the Loans to which such payment shall apply. In the absence of such
notice the Administrative Agent may specify the Loans to which such payment shall apply, but to the extent possible such payment or prepayment will be applied first to the Loans comprised of Base Rate Loans. 

Section 4.02 Pro Rata Treatment. Except to the extent otherwise provided herein each Lender agrees that: (i) each borrowing
from the Lenders under Section 2.01 and each continuation and conversion under Section 2.02 shall be made from the Lenders pro rata in accordance with their Percentage Share, each payment of commitment fee or other fees under
Section 2.04 shall be made for account of the Administrative Agent or the Lenders pro rata in accordance with their Percentage Share, and each termination or reduction of the amount of the Aggregate Maximum Revolving Credit Amounts under

of a year of 365 or 366 days, as the case may be. Interest on Base Rate Loans, and the commitment fee, Letter of Credit fees and other fees under Section 2.04 shall be computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed (including the first day but excluding the last day) occurring in the period for which such interest is payable. 

Section 4.04 Non-Receipt of Funds by the Administrative Agent. Unless the Administrative Agent shall have been notified by a
Lender or the Borrower prior to the date on which such notifying party is scheduled to make payment to the Administrative Agent (in the case of a Lender) of the proceeds of a Loan or a payment under a Letter of Credit to be made by it hereunder or
(in the case of the Borrower) a payment to the Administrative Agent for account of one or more of the Lenders hereunder (such payment being herein called the “Required Payment”), which notice shall be effective upon receipt,
that it does not intend to make the Required Payment to the Administrative Agent, the Administrative Agent may assume that the Required Payment has been made and may, in reliance upon such assumption (but shall not be required to), make the amount
thereof available to the intended recipient(s) on such date and, if such Lender or the Borrower (as the case may be) has not in fact made the Required Payment to 

  
 -42- 

 
the Administrative Agent, the recipient(s) of such payment shall, on demand, repay to the Administrative Agent the amount so made available together with interest thereon in respect of each day
during the period commencing on the date such amount was so made available by the Administrative Agent until, but excluding, the date the Administrative Agent recovers such amount at a rate per annum which, for any Lender as recipient, will be equal
to the Federal Funds Rate, and for the Borrower as recipient, will be equal to the Base Rate plus the Applicable Margin. 

Section 4.05 Set-off, Sharing of Payments, etc. 

(a) Right of Set-off. The Borrower agrees that, in addition to (and without limitation of) any right of set-off, bankers’ lien or
counterclaim a Lender may otherwise have, each Lender shall have the right and be entitled (after consultation with the Administrative Agent), at its option, to offset balances held by it or by any of its Affiliates for account of the Borrower or
any Subsidiary at any of its offices, in Dollars or in any other currency, against any principal of or interest on any of such Lender’s Loans, or any other amount payable to such Lender hereunder, which is not paid when due (regardless of
whether such balances are then due to the Borrower), in which case it shall promptly notify the Borrower and the Administrative Agent thereof, provided that such Lender’s failure to give such notice shall not affect the validity thereof.

 (b) Adjustments upon Set-off. If any Lender shall obtain payment of any principal of or interest on any Loan made by it to the
Borrower under this Agreement (or reimbursement as to any Letter of Credit) through the exercise of any right of set-off, banker’s lien or counterclaim or similar right or otherwise, and, as a result of such payment, such Lender shall have
received a greater percentage of the principal or interest (or reimbursement) then due hereunder by the Borrower to such Lender than the percentage received by any other Lenders, it shall promptly (i) notify the Administrative Agent and each
other Lender thereof and (ii) purchase from such other Lenders participation in (or, if and to the extent specified by such Lender, direct interests in) the Loans (or participations in Letters of Credit and Swing Line Loans) made by such other
Lenders (or in interest due thereon, as the case may be) in such amounts, and make such other adjustments from time to time as shall be equitable, to the end that all the Lenders shall share the benefit of such excess payment (net of any expenses
which may be incurred by such Lender in obtaining or preserving such excess payment) pro rata in accordance with the unpaid principal and/or interest on the Loans held by each of the Lenders (or reimbursements of Letters of Credit or funding
participations of Swing Line Loans). To such end all the Lenders shall make appropriate adjustments among themselves (by the resale of participations sold or otherwise) if such payment is rescinded or must otherwise be restored. The Borrower agrees
that any Lender so purchasing a participation (or direct interest) in the Loans made by other Lenders (or in interest due thereon, as the case may be) may exercise all rights of set-off, banker’s lien, counterclaim or similar rights with
respect to such participation as fully as if such Lender were a direct holder of Loans (or Letters of Credit and Swing Line Loans) in the amount of such participation. Nothing contained herein shall require any Lender to exercise any such right or
shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower. If under any applicable bankruptcy, insolvency or other similar law, any
Lender receives a secured claim in lieu of a set-off to which this Section 4.05 applies, such Lender shall, to the extent practicable, exercise its rights in respect of such secured claim in a manner consistent with the rights of the Lenders
entitled under this Section 4.05 to share the benefits of any recovery on such secured claim. 

  
 -43- 

 Section 4.06 Taxes. 

(a) Payments Free and Clear. Any and all payments by the Borrower hereunder shall be made, in accordance with Section 4.01, free
and clear of and without deduction for any and all present or future taxes, levies, imposts, deductions, charges or withholdings, or other taxes and all liabilities with respect thereto, excluding, in the case of each Lender, the Issuing Bank
and the Administrative Agent, Excluded Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to the Lenders, the Issuing Bank or the Administrative Agent (i) the sum payable shall be
increased by the amount necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 4.06) such Lender, the Issuing Bank or the Administrative Agent (as the case may be)
shall receive an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make such deductions and (iii) the Borrower shall pay the full amount deducted to the relevant taxing authority or
other Governmental Authority in accordance with applicable law. 
 (b) Other Taxes. In addition, to the fullest extent permitted by
applicable law, the Borrower agrees to pay any present or future stamp or documentary taxes or any other excise or property taxes, charges or similar levies that arise from any payment made hereunder or from the execution, delivery or registration
of, or otherwise with respect to, this Agreement, any Assignment or any Security Instrument (hereinafter referred to as “Other Taxes”). 

(c) Indemnification. To the fullest extent permitted by applicable law, the Borrower will indemnify each Lender, the Issuing Bank and
the Administrative Agent for the full amount of Taxes and Other Taxes (including, but not limited to, any Taxes or Other Taxes imposed by any Governmental Authority on amounts payable under this Section 4.06) paid by such Lender, the Issuing
Bank or the Administrative Agent (on their behalf or on behalf of any Lender), as the case may be, and any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such Taxes or Other Taxes
were correctly or legally asserted unless the payment of such Taxes was not correctly or legally asserted and such Lender’s payment of such Taxes or Other Taxes was the result of its gross negligence or willful misconduct. Any payment pursuant
to such indemnification shall be made within thirty (30) days after the date any Lender, the Issuing Bank or the Administrative Agent, as the case may be, makes written demand therefor. If any Lender, the Issuing Bank or the Administrative
Agent receives a refund or credit in respect of any Taxes or Other Taxes for which such Lender, Issuing Bank or the Administrative Agent has received payment from the Borrower it shall promptly notify the Borrower of such refund or credit and shall,
if no Default has occurred and is continuing, within thirty (30) days after receipt of a request by the Borrower (or promptly upon receipt, if the Borrower has requested application for such refund or credit pursuant hereto), pay an amount
equal to such refund or credit to the Borrower without interest (but with any interest so refunded or credited), provided that the Borrower, upon the request of such Lender, the Issuing Bank or the Administrative Agent, agrees to return such refund
or credit (plus penalties, interest or other charges) to such Lender, the Issuing Bank or the Administrative Agent in the event such Lender, the Issuing Bank or the Administrative Agent is required to repay such refund or credit. 

  
 -44- 

 (d) Lender Representations. (i) Each Lender represents that it is either (1) a
banking association or corporation organized under the laws of the United States of America or any state thereof or (2) it is entitled to complete exemption from United States withholding tax imposed on or with respect to any payments,
including fees, to be made to it pursuant to this Agreement (a) under an applicable provision of a tax convention to which the United States of America is a party or (b) because it is acting through a branch, agency or office in the United
States of America and any payment to be received by it hereunder is effectively connected with a trade or business in the United States of America. Each Lender agrees to indemnify and hold harmless the Borrower or Administrative Agent, as
applicable, from any United States taxes, penalties, interest and other expenses, costs and losses incurred or payable by (i) the Administrative Agent as a result of such Lender’s failure to submit any form or certificate that it is
required to provide pursuant to this Section 4.06 or (ii) the Borrower or the Administrative Agent as a result of their reliance on any such form or certificate which such Lender has provided to them pursuant to this Section 4.06.

 (ii) Each Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the
jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at
the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate.
Without limiting the generality of the foregoing: 
 (A) each Foreign Lender shall deliver to the Borrower and the
Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the
Borrower or the Administrative Agent), whichever of the following is applicable: 
 (1) in the case of a Foreign Lender
claiming the benefits of an income tax treaty to which the U.S. is a party (x) with respect to payments of interest under any Loan Document, executed originals of IRS Form W-8BEN establishing an exemption
from, or reduction of, U.S. federal withholding tax pursuant to the “interest” article of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN establishing an exemption from,
or reduction of, U.S. federal withholding tax pursuant to the “business profits” or “other income” article of such tax treaty; 

(2) executed originals of IRS Form W-8ECI; 

  
 -45- 

 (3) in the case of a Foreign Lender claiming the benefits of the exemption for
portfolio interest under Section 881(c) of the Code, (x) a certificate substantially in the form of Exhibit F-1 to the effect that such Foreign Lender is not a “bank” within the meaning of Section 881(c)(3)(A) of
the Code, a “10 percent shareholder” of any Co-Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in
Section 881(c)(3)(C) of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed originals of IRS Form W-8BEN; or 

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

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

(iii) For any period with respect to which a Lender has failed to provide the Borrower with the form required pursuant to this
Section 4.06, if any, (other than if such failure is due to a change in a Governmental Requirement occurring subsequent to the date on which a form originally was required to be provided), such Lender shall not be entitled to indemnification
under Section 4.06 with respect to taxes imposed by the United States which taxes would not have been imposed but for such failure to provide such forms; provided, however, that if a Lender, which is otherwise exempt from or
subject to a reduced rate of withholding tax, becomes subject to taxes because of its failure to deliver a form required hereunder, the Borrower shall take such steps as such Lender shall reasonably request to assist such Lender to recover such
taxes. 
 (iv) Any Lender claiming any additional amounts payable pursuant to this Section 4.06 shall use reasonable
efforts (consistent with legal and regulatory restrictions) to file any certificate or document requested by the Borrower or the Administrative Agent or to change the jurisdiction of its Applicable Lending Office or to contest any tax

  
 -46- 

 
imposed if the making of such a filing or change or contesting such tax would avoid the need for or reduce the amount of any such additional amounts that may thereafter accrue and would not, in
the sole determination of such Lender, be otherwise disadvantageous to such Lender. 
 (e) FATCA. If a payment made to a Lender under
any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code,
as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by
applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative
Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this
clause (f), “FATCA” shall include any amendments made to FATCA after the date of this Agreement. 
 (f) U.S. Lenders.
Any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the
Borrower or the Administrative Agent), executed originals of IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding Tax. 

Section 4.07 Disposition of Proceeds. The Mortgage contains an assignment by the Borrower unto and in favor of the Administrative
Agent for the benefit of the Beneficiaries of all production and all proceeds attributable thereto which may be produced from or allocated to the Mortgaged Property, and the Mortgage further provides in general for the application of such proceeds
to the satisfaction of the Obligations and other indebtedness, liabilities and obligations described therein and secured thereby. Notwithstanding the assignment contained in the Mortgage, until the occurrence of an Event of Default, the Lenders
agree that they will neither notify the purchaser or purchasers of such production nor take any other action to cause such proceeds to be remitted to the Lenders, but the Lenders will instead permit such proceeds to be paid to the Borrower. 

Section 4.08 Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a
Defaulting Lender, the following provisions shall apply for so long as such Lender is a Defaulting Lender: 
 (a) fees shall cease to accrue
on the unfunded portion of the Commitment of such Defaulting Lender pursuant to Section 2.04(a); 
 (b) the Maximum Revolving Credit
Amount and Credit Exposure of such Defaulting Lender shall not be included in determining whether all Lenders, the Required Lenders or the Majority Lenders have taken or may take any action hereunder (including any consent to any amendment or waiver
pursuant to Section 12.04), provided that any waiver, 

  
 -47- 

 
amendment or modification requiring the consent of all Lenders or each affected Lender which affects such Defaulting Lender differently than other affected Lenders or which increases or extends
the Commitment of such Lender or reduces or extends the final maturity of the Loans owed to such Lender or reduces the principal amount thereof shall require the consent of such Defaulting Lender; 

(c) any payment of principal, interest, fees or other amounts received by the Administrative Agent for the account of such Defaulting Lender
(whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to Section 4.05 shall be applied at such time or times as may be determined by the
Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment on a pro rata basis of any amounts owing by such Defaulting Lender to
the Issuing Bank or the Swing Line Lender hereunder; third, to cash collateralize the LC Exposure with respect to such Defaulting Lender in accordance with Section 4.08(d)(ii); fourth, as the Borrower may request (so long as no
Default or Event of Default exists), to the funding of any Loan in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this Agreement, as determined by the Administrative Agent; fifth, if so
determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (x) satisfy such Defaulting Lender’s potential future funding obligations with respect to Loans under this Agreement
and (y) cash collateralize any future LC Exposure with respect to such Defaulting Lender with respect to future Letters of Credit issued under this Agreement, in accordance with Section 4.08(d)(ii); sixth, to the payment of any
amounts owing to the Lenders, the Issuing Bank or the Swing Line Lender as a result of any final and nonappealable judgment of a court of competent jurisdiction obtained by any Lender, the Issuing Bank or the Swing Line Lender against such
Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any
final and nonappealable judgment of a court of competent jurisdiction obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such
Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if (x) such payment is a payment of the principal amount of any Loans or LC Disbursements in respect of which such Defaulting Lender has not
fully funded its appropriate share, and (y) such Loans were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment shall be applied solely to pay the
Loans of, and LC Disbursements owed to, all non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or LC Disbursements owed to, such Defaulting Lender until such time as all Loans and funded and unfunded
participations in LC Obligations and Swing Line Loans are held by the Lenders pro rata in accordance with their respective Percentage Shares (without giving effect to Section 4.08(d)(i)). Any payments, prepayments or other amounts paid or
payable to a Defaulting Lender that are applied (or held) to pay amounts owed by a Defaulting Lender or to post cash collateral pursuant to this Section 4.08 shall be deemed paid to and redirected by such Defaulting Lender, and each Lender
irrevocably consents hereto; 

  
 -48- 

 (d) if any Swing Line Exposure or LC Exposure exists at the time a Lender becomes a Defaulting
Lender then: 
 (i) all or any part of such Defaulting Lender’s participation in LC Obligations and Swing Line Loans
shall be reallocated among the non-Defaulting Lenders in accordance with their respective Percentage Shares (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that (x) the conditions set forth in
Section 6.02 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the Borrower shall be deemed to have represented and warranted that such conditions are
satisfied at such time), and (y) such reallocation does not cause the Credit Exposure of any non-Defaulting Lender to exceed such non-Defaulting Lender’s Commitment. No reallocation hereunder shall constitute a waiver or release of any
claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting Lender, including any claim of a non-Defaulting Lender as a result of such non-Defaulting Lender’s increased exposure following such
reallocation; and 
 (ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected,
the Borrower shall, within one Business Day following notice by the Administrative Agent, (x) cash collateralize such Defaulting Lender’s Percentage Share of the Swing Line Exposure and (y) cash collateralize such Defaulting
Lender’s Percentage Share of the LC Exposure (in each case, after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.10; provided that cash
collateral (or the appropriate portion thereof) provided to reduce any LC Exposure shall no longer be required to be held as cash collateral pursuant to this Section 4.08 following (x) the elimination of the applicable LC Exposure
(including by the termination of Defaulting Lender status of the applicable Lender), or (y) the determination by the Administrative Agent and the Issuing Bank that there exists excess cash collateral; provided, further, that,
subject to this Section 4.8 the Person providing cash collateral and the Issuing Bank may agree that cash collateral shall be held to support future anticipated LC Exposure or other obligations; 

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to clause (ii)
above, the Borrower shall not be required to pay any Letter of Credit fees for the account of such Defaulting Lender pursuant to Section 2.04(b) with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting
Lender’s LC Exposure is cash collateralized; 
 (iv) if the LC Exposure of the non-Defaulting Lenders is reallocated
pursuant to clause (i) above, then the fees payable to the Lenders pursuant to Section 2.04(b) shall be adjusted in accordance with such non-Defaulting Lenders’ Percentage Share; or 

(v) if any Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this
Section 4.08, then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all commitment fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such
Defaulting Lender’s Commitment that was utilized by such LC Exposure) and letter of credit fees payable under Section 2.04(b) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until such LC
Exposure is cash collateralized and/or reallocated; 

  
 -49- 

 (e) so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to
issue, amend or increase any Letter of Credit, unless it is satisfied that the related LC Exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with
Section 2.10, and participating interests in any such newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 4.08(c)(i) (and Defaulting Lenders shall not participate
therein); and 
 (f) if the Borrower, the Administrative Agent, the Swing Line Lender and the Issuing Bank agree in writing that a Lender is
no longer a Defaulting Lender, the Administrative Agent will so notify the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to
any cash collateral), that Lender will, to the extent applicable, purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and
funded and unfunded participations in Letters of Credit and Swing Line Loans to be held pro rata by the Lenders in accordance with their respective Percentage Shares (without giving effect to Section 4.08(d)(i)), whereupon such Lender will
cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided,
further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that
Lender’s having been a Defaulting Lender. 
 ARTICLE V 

CAPITAL ADEQUACY AND ADDITIONAL COSTS 

Section 5.01 Capital Adequacy and Additional Costs. 

(a) Capital and Liquidity Regulations. If any Lender determines that any Change in Law affecting such Lender or any lending office of
such Lender or such Lender’s holding company, if any, regarding capital or liquidity requirements, has or would have the effect of reducing the rate of return on such Lender’s capital or on the capital of such Lender’s holding
company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by such Lender to a level below that which such Lender or such Lender’s holding company could
have achieved but for such Change in Law (taking into consideration such Lender’s policies and the policies of such Lender’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender or such Lender’s holding company for any such reduction suffered. Each Lender will notify the Borrower that it is entitled to compensation pursuant to this Section 5.01(a) as
promptly as practicable after it determines to request such compensation. 

  
 -50- 

 (b) LIBOR Regulations, etc. The Borrower shall pay directly to each Lender from time to
time such amounts as such Lender may determine to be necessary to compensate such Lender for any costs which it determines are attributable to its making or maintaining of any LIBOR Loans or issuing or participating in Letters of Credit or making,
maintaining or participating in Swing Line Loans or its obligation to make any LIBOR Loans or Swing Line Loans or issue or participate in any Letters of Credit or Swing Line Loans hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any of such LIBOR Loans, Letters of Credit or Swing Line Loans or such obligation (such increases in costs and reductions in amounts receivable being herein called “Additional Costs”), resulting from
any Change in Law which: (i) changes the basis of taxation of any amounts payable to such Lender under this Agreement or any Note in respect of any of such LIBOR Loans or Letters of Credit (other than taxes imposed on the overall net income of
such Lender or of its Applicable Lending Office for any of such LIBOR Loans or Swing Line Loans by the jurisdiction in which such Lender has its principal office or Applicable Lending Office); or (ii) imposes or modifies any reserve, special
deposit, insurance, minimum capital, capital ratio or similar requirements relating to any extensions of credit or other assets of, or any deposits with or other liabilities of such Lender, or the Commitment or Loans of such Lender or the LIBOR
interbank market; or (iii) imposes any other condition affecting this Agreement or any Note (or any of such extensions of credit or liabilities) or such Lender’s Commitment or Loans. Each Lender will notify the Administrative Agent and the
Borrower of any event occurring after the Closing Date which will entitle such Lender to compensation pursuant to this Section 5.01(b) as promptly as practicable after it obtains knowledge thereof and determines to request such compensation,
and will designate a different Applicable Lending Office for the Loans of such Lender affected by such event if such designation will avoid the need for, or reduce the amount of, such compensation and will not, in the sole opinion of such Lender, be
disadvantageous to such Lender, provided that such Lender shall have no obligation to so designate an Applicable Lending Office located in the United States. 

(c) Change in Law. Without limiting the effect of the provisions of Section 5.01(b), in the event that at any time (by reason of
any Change in Law or any other circumstances arising after the Closing Date affecting (a) any Lender, (b) the LIBOR interbank market or (c) such Lender’s position in such market), the LIBOR Rate, as determined in good
faith by such Lender, will not adequately and fairly reflect the cost to such Lender of funding its LIBOR Loans, then, if such Lender so elects, by notice to the Borrower and the Administrative Agent, the obligation of such Lender to make additional
LIBOR Loans shall be suspended until such Change in Law or other circumstances ceases to be in effect (in which case the provisions of Section 5.04 shall be applicable). 

(d) Compensation Procedure. Any Lender notifying the Borrower of the incurrence of Additional Costs under this Section 5.01 shall
in such notice to the Borrower and the Administrative Agent set forth in reasonable detail the basis and amount of its request for compensation. Determinations and allocations by each Lender for purposes of this Section 5.01 of the effect of
any Change in Law pursuant to Section 5.01(b) or (c), or of the effect of capital maintained pursuant to Section 5.01(a), on its costs or rate of return of maintaining Loans or its obligation to make Loans or issue Letters of
Credit, or on amounts receivable by it in respect of Loans or Letters of Credit, and of the amounts required to compensate such Lender under this Section 5.01, shall be conclusive and binding for all purposes absent manifest error,
provided 

  
 -51- 

 
that such determinations and allocations are made on a reasonable basis. Any request for additional compensation under this Section 5.01 shall be paid by the Borrower within thirty
(30) days of the receipt by the Borrower of the notice described in this Section 5.01. 
 Section 5.02 Limitation on LIBOR
Loans. Anything herein to the contrary notwithstanding, if, on or prior to the determination of any LIBOR Rate for any Interest Period: 

(a) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that quotations of interest rates for
the relevant deposits referred to in the definition of “LIBOR Rate” in Section 1.02 are not being provided in the relevant amounts or for the relevant maturities for purposes of determining rates of interest for LIBOR Loans as
provided herein; or 
 (b) the Administrative Agent determines (which determination shall be conclusive, absent manifest error) that the
relevant rates of interest referred to in the definition of “LIBOR Rate” in Section 1.02 upon the basis of which the rate of interest for LIBOR Loans for such Interest Period is to be determined are not sufficient to adequately cover
the cost to the Lenders of making or maintaining LIBOR Loans; 
 then the Administrative Agent shall give the Borrower prompt notice thereof, and so long as
such condition remains in effect, the Lenders shall be under no obligation to make additional LIBOR Loans. 
 Section 5.03
Illegality. Notwithstanding any other provision of this Agreement, in the event that it becomes unlawful for any Lender or its Applicable Lending Office to honor its obligation to make or maintain LIBOR Loans hereunder, then such Lender shall
promptly notify the Borrower thereof and such Lender’s obligation to make LIBOR Loans shall be suspended until such time as such Lender may again make and maintain LIBOR Loans (in which case the provisions of Section 5.04 shall be
applicable). 
 Section 5.04 Base Rate Loans Pursuant to Sections 5.02 and 5.03. If the obligation of any Lender to make
LIBOR Loans shall be suspended pursuant to Sections 5.02 or 5.03 (“Affected Loans”), all Affected Loans which would otherwise be made by such Lender shall be made instead as Base Rate Loans (and, if an event referred to
in Section 5.03 has occurred and such Lender so requests by notice to the Borrower, all Affected Loans of such Lender then outstanding shall be automatically converted into Base Rate Loans on the date specified by such Lender in such notice)
and, to the extent that Affected Loans are so made as (or converted into) Base Rate Loans, all payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its Base Rate Loans. 

Section 5.05 Compensation. The Borrower shall pay to each Lender within thirty (30) days of receipt of written request of
such Lender (which request shall set forth, in reasonable detail, the basis for requesting such amounts and which shall be conclusive and binding for all purposes absent manifest error and provided that such determinations are made on a reasonable
basis), such amount or amounts as shall compensate it for any actual loss, cost, expense or liability which such Lender determines are attributable to: 

  
 -52- 

 (a) any payment, prepayment or conversion of a LIBOR Loan properly made by such Lender or the
Borrower for any reason (including, without limitation, the acceleration of the Loans pursuant to Section 10.01) on a date other than the last day of the Interest Period for such Loan; or 

(b) any failure by the Borrower for any reason (including but not limited to, the failure of any of the conditions precedent specified in
Article VI to be satisfied) to borrow, continue or convert a LIBOR Loan from such Lender on the date for such borrowing, continuation or conversion specified in the relevant notice given pursuant to Section 2.02(c). 

Section 5.06 Replacement Lenders. (a) If (i) any Lender has notified the Borrower and the Administrative Agent of its
incurring any costs under Section 5.01 or asserts an illegality under Section 5.03, (ii) any Lender has required the Borrower to make payments for Taxes under Section 4.06, (iii) any Lender refuses to consent to any
amendment, waiver or other modification of any Loan Document requested by the Borrower that requires the consent of all Lenders or each Lender affected and such amendment, waiver or other modification is consented to by the Required Lenders,
(iv) any Lender fails to approve an increase in the Borrowing Base which has been approved by the Required Lenders or (v) any Lender shall become a Defaulting Lender, then the Borrower may, in whole but not in part, terminate the
Commitment of any such Lender (the “Terminated Lender”) at any time upon five (5) Business Days’ prior written notice to the Terminated Lender and the Administrative Agent (such notice referred to herein as a
“Notice of Termination”). 
 (b) In order to effect the termination of the Commitment of the Terminated Lender, the
Borrower shall: (i) obtain an agreement with one or more Lenders to increase their Commitment or Commitments and/or (ii) request any one or more other banking institutions to become parties to this Agreement in place and instead of such
Terminated Lender and agree to accept a Commitment or Commitments; provided, however, that such one or more other banking institutions are reasonably acceptable to the Administrative Agent, the Swing Line Lender and the Issuing Bank
and become parties by executing an Assignment (the Lenders or other banking institutions that agree to accept in whole or in part the Commitment of the Terminated Lender being referred to herein as the “Replacement Lenders”),
such that the aggregate increased and/or accepted Commitments of the Replacement Lenders under clauses (i) and (ii) above equal the Commitment of the Terminated Lender. 

(c) The Notice of Termination shall include the name of the Terminated Lender, the date the termination will occur (the “Lender
Termination Date”), and the Replacement Lender or Replacement Lenders to which the Terminated Lender will assign its Commitment and, if there will be more than one Replacement Lender, the portion of the Terminated Lender’s
Commitment to be assigned to each Replacement Lender. 
 (d) On the Lender Termination Date, (i) the Terminated Lender shall by
execution and delivery of an Assignment assign its Commitment to the Replacement Lender or Replacement Lenders (pro rata, if there is more than one Replacement Lender, in proportion to the portion of the Terminated Lender’s Commitment to be
assigned to each Replacement Lender) indicated in the Notice of Termination and shall assign to the Replacement Lender or Replacement Lenders each of its Loans (if any) then outstanding and participation interests in

  
 -53- 

 
Letters of Credit (if any) then outstanding pro rata as aforesaid), (ii) the Terminated Lender shall assign its Loans and Commitments, without recourse, representation or warranty to the
Replacement Lender or Replacement Lenders (pro rata as aforesaid), (iii) the Replacement Lender or Replacement Lenders shall purchase the Loans and Commitments of the Terminated Lender (pro rata as aforesaid) at a price equal to the unpaid
principal amount thereof plus interest and facility and other fees accrued and unpaid to the Lender Termination Date, and (iv) the Replacement Lender or Replacement Lenders will thereupon (pro rata as aforesaid) succeed to and be substituted in
all respects for the Terminated Lender with like effect as if becoming a Lender pursuant to the terms of Section 12.06(b), and the Terminated Lender will have the rights and benefits of an assignor under Section 12.06(b). To the extent not
in conflict, the terms of Section 12.06(b) shall supplement the provisions of this Section 5.06(d). For each assignment made under this Section 5.06, the Replacement Lender shall pay to the Administrative Agent the processing fee
provided for in Section 12.06(b). The Borrower will be responsible for the payment of any actual breakage costs associated with termination and Replacement Lenders, as set forth in Section 5.05.

Section 7.04 No Breach. Neither the execution and delivery of the Loan Documents, nor compliance with the terms and provisions
hereof will conflict with or result in a breach of, or require any consent which has not been obtained as of the Closing Date under, the respective charter, by-laws, or limited liability company agreement of the Borrower or any Subsidiary, or any

Documents. 
 Section 7.05 Authority. The Borrower and each Subsidiary have all necessary power and authority to execute,
deliver and perform its obligations under the Loan Documents to which it is a party; and the execution, delivery and performance by the Borrower and each Subsidiary of the Loan Documents to which it is a party, have been duly authorized by all

hereunder will be used to buy or carry any margin stock. 
 Section 7.08 ERISA. Except as would not reasonably be expected to
result in a Material Adverse Effect: 
 (a) The Borrower, each Subsidiary and each ERISA Affiliate have complied with ERISA and, where
applicable, the Code regarding each Plan. 
 (b) No act, omission or transaction has occurred which could result in imposition on the
Borrower, any Subsidiary or any ERISA Affiliate (whether directly or indirectly) of (i) either a civil penalty assessed pursuant to Section 502(c), (i) or (l) of ERISA or a tax imposed pursuant to Chapter 43 of
Subtitle D of the Code or (ii) breach of fiduciary duty liability damages under Section 409 of ERISA.

to any assessment received by the Borrower or any Subsidiary, except (a) as set out in Schedule 7.09, (b) Taxes that are being contested in good faith by appropriate proceedings and for which the

  
 -59- 

 
Borrower or such Subsidiary, as applicable, has set aside on its books adequate reserves in accordance with GAAP or (c) to the extent that the failure to do so could not reasonably be
expected to result in a Material Adverse Effect. The charges, accruals and reserves on the books of the Borrower and its Subsidiaries in respect of taxes and other governmental charges are, in the opinion of the Borrower, adequate. No tax lien has
been filed and, to the knowledge of the Borrower, no claim is being asserted with respect to any such tax, fee or other charge. 

Section 7.10 Titles, etc. 

(a) Except as set out in Schedule 7.10, each of the Borrower and its Subsidiaries has good and defensible title to its
material (individually or in the aggregate) Properties, including, free and clear of all Liens, except Liens permitted by Section 9.02. Except as set forth in Schedule 7.10, after giving full effect to the Excepted Liens, the
Borrower and the Guarantors own the net interests in production attributable to the Hydrocarbon Interests reflected in the most recently delivered Reserve Report and the ownership of such Properties shall not in any material respect obligate the
Borrower or any Guarantor to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Reserve
Report without a proportional increase in the associated net revenue interest. Except as would not reasonably be expected to affect in any material respect the conduct of the business of the Borrower and its Subsidiaries taken as a whole, all leases
and agreements necessary for the conduct of the business of the Borrower and its Subsidiaries are valid and subsisting, in full force and effect (including as to depths) and there exists no default or event or circumstance which with the giving of
notice or the passage of time or both would give rise to a default by the Borrower and/or its Subsidiaries, and to the best of the Borrower’s knowledge, there exists no default or event or circumstance which with the giving of notice or the
passage of time or both would give rise to a default by a third party, under any such lease or leases, which would affect in any material respect the conduct of the business of the Borrower and its Subsidiaries taken as a whole. 

(b) The rights, Properties and other assets presently owned, leased or licensed by the Borrower and its Subsidiaries including, without
limitation, all easements and rights of way, include all rights, Properties and other assets necessary to permit the Borrower and its Subsidiaries to conduct their business in all material respects in the same manner as its business has been
conducted prior to the Closing Date. 
 (c) All of the assets and Properties of the Borrower and its Subsidiaries which are reasonably
necessary for the operation of its business are in operable working condition (ordinary wear and tear excepted) and are maintained in accordance with prudent business standards. 

Section 7.11 No Material Misstatements. No written information, statement, exhibit, certificate, document or report furnished to
the Administrative Agent and the Lenders (or any of them) by the Borrower or any Subsidiary in connection with the negotiation of this Agreement contained any material misstatement of fact or omitted to state a material fact or any fact necessary to
make the statement contained therein not materially misleading in the light of the circumstances in which made and with respect to the Borrower and its Subsidiaries taken as a 

  
 -60- 

 
whole. There are no statements or conclusions in any Reserve Report which are based upon or include misleading material information or fail to take into account material information regarding the
matters reported therein, it being understood that projections concerning volumes attributable to the Oil and Gas Properties of the Borrower and its Subsidiaries and production and cost estimates contained in each Reserve Report are necessarily
based upon professional opinions, estimates and projections and that the Borrower and its Subsidiaries do not warrant that such opinions, estimates and projections will ultimately prove to have been accurate. 

Section 7.12 Investment Company Act. Neither the Borrower nor any Subsidiary is an “investment company” or a company
“controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended.

of each Subsidiary are located at the addresses stated on Schedule 7.14. 
 Section 7.15 Defaults. Neither the
Borrower nor any Subsidiary is in default under any Material Agreement nor has any event or circumstance occurred which, but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default by the
Borrower and/or its Subsidiaries under any Material Agreement, in each case, which default could reasonably be expected to have a Material Adverse Effect, and to the best of the Borrower’s knowledge, no event or circumstance has occurred which,
but for the expiration of any applicable grace period or the giving of notice, or both, would constitute a default by a third party under any Material Agreement to which the Borrower or any Subsidiary is a party or by which the Borrower or any
Subsidiary is bound which default could have a Material Adverse Effect. No Default hereunder has occurred and is continuing. 

Section 7.16 Environmental Matters. Except (i) as provided in Schedule 7.16 or (ii) as would not have a
Material Adverse Effect (or with respect to (c), (d) and (e) below, where the failure to take such actions would not have a Material Adverse Effect): 

(a) Neither any Property of the Borrower or any Subsidiary nor the operations conducted thereon, or any failure to act, violate any order or
requirement of any court or Governmental Authority or any Environmental Laws; 
 (b) Without limitation of clause (a) above, no Property
of the Borrower or any Subsidiary nor the operations currently conducted thereon, or any failure to act, or, to the best knowledge of the Borrower, by any prior owner or operator of such Property or operation, are in violation of or subject to any
existing, pending or threatened action, suit, investigation, inquiry or proceeding by or before any court or Governmental Authority or to any remedial obligations under Environmental Laws; 

  
 -61- 

 (c) All notices, permits, licenses or similar authorizations, if any, required to be obtained or
filed in connection with the operation or use of any and all Property of the Borrower and each Subsidiary, including without limitation past or present treatment, storage, disposal or release of a hazardous substance or solid waste into the
environment, have been duly obtained or filed, and the Borrower and each Subsidiary are in compliance with the terms and conditions of all such notices, permits, licenses and similar authorizations; 

(d) All hazardous substances, solid waste, and oil and gas exploration and production wastes, if any, generated at any and all Property of the
Borrower or any Subsidiary have in the past been transported, treated and disposed of in accordance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment, and, to the
best knowledge of the Borrower, all such transport carriers and treatment and disposal facilities have been and are operating in compliance with Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or
welfare or the environment, and are not the subject of any existing, pending or threatened action, investigation or inquiry by any Governmental Authority in connection with any Environmental Laws; 

(e) The Borrower has taken all steps reasonably necessary to determine and has determined that no hazardous substances, solid waste, or oil and
gas exploration and production wastes, have been disposed of or otherwise released and there has been no threatened release of any hazardous substances on or to any Property of the Borrower or any Subsidiary except in material compliance with
Environmental Laws and so as not to pose an imminent and substantial endangerment to public health or welfare or the environment; 
 (f) To
the extent applicable, all Property of the Borrower and each Subsidiary currently satisfies all design, operation, and equipment requirements imposed by the OPA or scheduled as of the Closing Date to be imposed by OPA during the term of this
Agreement, and the Borrower does not have any reason to believe that such Property, to the extent subject to OPA, will not be able to maintain compliance with the OPA requirements during the term of this Agreement; and 

(g) Neither the Borrower nor any Subsidiary has any known contingent liability under Environmental Laws in connection with any generation,
storage, release or threatened release, transportation, or disposal of any oil, hazardous substance or solid waste into the environment. 

Section 7.17 Compliance with the Law. Neither the Borrower nor any Subsidiary has violated any Governmental Requirement or failed
to obtain any license, permit, franchise or other governmental authorization necessary for the ownership of any of its Properties or the conduct of its business, which violation or failure would have (in the event such violation or failure were
asserted by any Person through appropriate action) a Material Adverse Effect. Except for such acts or failures to act as would not have a Material Adverse Effect, the Oil and Gas Properties of the Borrower and its Subsidiaries (and properties
unitized therewith) have been maintained, operated and developed in a good and workmanlike manner and in conformity with all applicable laws and all rules, regulations and orders of all duly constituted authorities having jurisdiction and in
conformity with the provisions of all leases, subleases or 

  
 -62- 

 
other contracts comprising a part of the Hydrocarbon Interests and other contracts and agreements forming a part of such Oil and Gas Properties; specifically in this connection, after the Closing
Date, no such Oil and Gas Property is subject to having allowable production reduced below the full and regular allowable (including the maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the
time) prior to the Closing Date. 
 Section 7.18 Insurance. The Borrower has, and has caused all of its Subsidiaries to have,
insurance policies as are sufficient for compliance with all requirements of law and of all agreements to which the Borrower or any such Subsidiary is a party; such policies are valid, outstanding and enforceable policies; provide adequate insurance
coverage in at least such amounts and against at least such risks (but including in any event public liability) as are usually insured against in the same general area by companies engaged in the same or a similar business for the assets and
operations of the Borrower and each Subsidiary; all such policies name the Administrative Agent as additional insured and loss payee. 

Section 7.19 Hedge Agreements. Schedule 7.19 sets forth as of the Closing Date, and after the date hereof, each report
required to be delivered by the Borrower pursuant to Section 8.01(i) sets forth, a true and complete list of all Hedge Agreements (including commodity price swap agreements, forward agreements or contracts of sale which provide for prepayment

each such agreement. 
 Section 7.20 Restriction on Liens. Neither the Borrower nor any Guarantor is a party to any agreement or
arrangement (other than this Agreement and the Security Instruments), or subject to any order, judgment, writ or decree, which either restricts or purports to restrict its ability to grant Liens to the Administrative Agent and/or the Lenders on or
in respect of their respective assets or Properties, except such restrictions in favor of the holders of Debt secured by Liens described in Sections 9.01(d) or 9.01(e) but only insofar as such restrictions pertain to the Property encumbered
thereby. 
 Section 7.21 Material Agreements. Set forth on Schedule 7.21 hereto is a complete and correct list of
all material financing agreements, leases (other than Hydrocarbon Interests), indentures, note purchase agreements, obligations in respect of letters of credit, guarantees, joint venture agreements, and other financing-related instruments in effect
or to be in effect as of the Closing Date (other than Hedge Agreements) providing for, evidencing, securing or otherwise relating to any material Debt of the Borrower, the Guarantors or any of the Borrower’s Subsidiaries, and all obligations of
the Borrower, the Guarantors or any of the Borrower’s Subsidiaries to issuers of surety or appeal bonds issued for account of the Borrower or any such Subsidiary, and such list correctly sets forth the names of the debtor or lessee and creditor
or lessor with respect to the Debt or lease obligations outstanding or to be outstanding and the Property subject to any Lien securing such Debt or lease obligation. Also set forth on Schedule 7.21 hereto is a complete and correct list
of all material agreements and other instruments of the Borrower, the Guarantors and Borrower’s Subsidiaries relating to the purchase, transportation by pipeline, gas processing, marketing, sale and supply of natural gas and other Hydrocarbons,
but in any event, any such agreement or other instrument that is expected to account for more than 10% of the consolidated sales of the Borrower, the Guarantors and any of the Borrower’s Subsidiaries during the Borrower’s current fiscal
year and which is not cancelable on thirty (30) or fewer days’ notice.

to Section 8.06(c), on a net basis there are no gas imbalances, take or pay or other prepayments with respect to the Oil and Gas Properties of the Borrower and its Subsidiaries which (taken together with the imbalances, take or pay, or other
prepayments on Schedule 7.23 or such certificate) would require the Borrower or its Subsidiaries to deliver, in the aggregate, after netting all over-production and under-production, three percent (3%) or more of the total volumes
of proved, producing reserves of Hydrocarbons (calculated on an mcf equivalent basis with each barrel of oil being equivalent to six mcf of natural gas) reflected in the Initial Reserve Reports or the most recent Reserve Report delivered pursuant to

which penalties attach thereto, except for any such tax, assessment, charge or levy the payment of which is being contested in good faith and by proper proceedings and against which adequate reserves are being maintained or the nonpayment of which

shall use commercially reasonable efforts to obtain endorsements containing provisions that such insurance policies will not be canceled without 30 days’ prior written notice having been given by the insurance company to the Administrative
Agent. 
 (b) Proof of Insurance. Contemporaneously with the delivery of the financial statements required by Section 8.01(a) to
be delivered for each year, the Borrower will furnish or cause to be furnished to the Administrative Agent and the Lenders a certificate of insurance coverage from the insurer in form and substance satisfactory to the Administrative Agent and, if

make all the reasonably necessary repairs, renewals and replacements so that at all times the state and condition of its Oil and Gas Properties and other material Properties will be fully preserved and maintained, except to the extent a portion of
such Properties is no longer capable of producing Hydrocarbons in economically reasonable amounts. Except where the failure to do so could not reasonably be expected to have a Material Adverse Effect, the Borrower will and will cause each Subsidiary

its Oil and Gas Properties, (ii) perform or make reasonable and customary efforts to cause to be performed, in accordance with industry standards, the obligations required by each and all of the assignments, deeds, leases, sub leases, contracts

Borrower who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding May 1 Reserve Report. 

(b) In the event of an unscheduled redetermination, the Borrower shall furnish to the Administrative Agent and the Lenders a Reserve Report
prepared by or under the supervision of the chief engineer of the Borrower who shall certify such Reserve Report to be true and accurate and to have been prepared in accordance with the procedures used in the immediately preceding Reserve Report

Administrative Agent as soon as possible, but in any event no later than thirty (30) days following the receipt of the request by the Administrative Agent. 

(c) With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders, a certificate from a

(a) Delivery. On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by
Section 8.06(a) and concurrently with the granting of the Lien or other action referred to in Section 8.08(b), to the extent requested by the Administrative Agent, the Borrower will deliver title information in form and substance
acceptable to the Administrative Agent (i) covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding Reserve Report, so that the Administrative Agent shall have received
together with title information previously delivered to the Administrative Agent, satisfactory title information on at least eighty percent (80%) of the PV-9 of the Oil and Gas Properties evaluated by such Reserve Report or (ii) the
properties referred to in Section 8.08(b), as applicable. 
 (b) Cure of Title Defects. The Borrower shall cure any title defects
or exceptions which are not Excepted Liens or Liens otherwise permitted by Section 9.02 raised by such information, or substitute acceptable Mortgaged Properties with no title defects or exceptions except for Excepted Liens or Liens otherwise
permitted by Section 9.02 covering Mortgaged Properties of an equivalent value, within 90 days after a request by the Administrative Agent or the Lenders to cure such defects or exceptions. 

(c) Failure to Cure Title Defects. If the Borrower is unable to cure any title defect requested by the Administrative Agent or the
Lenders to be cured within such 90-day period or the Borrower does not comply with the requirements to provide acceptable title information covering eighty percent (80%) of the PV-9 of the Oil and Gas Properties evaluated in the most recent
Reserve Report, such default shall not be a Default, but instead the Administrative Agent and the Required Lenders shall have the right to send a notice to the Borrower that the then outstanding Borrowing Base shall be reduced by an amount as
determined by the Required Lenders to reflect the economic value on the Borrowing Base of such defect. This new Borrowing Base shall become effective immediately after receipt of such notice. Such designation of the new Borrowing Base shall not
constitute an unscheduled redetermination pursuant to Section 2.08(c). 
 Section 8.08 Collateral. 

(a) Collateral. The Obligations shall be secured by a perfected first priority Lien (subject only to Excepted Liens or Liens otherwise
permitted by Section 9.02) granted to the Administrative Agent for the benefit of the Beneficiaries in (i) Oil and Gas Properties having not less than 80% of the PV-9 reflected in the most recently delivered Reserve Report, (ii) the
other material personal property of the Borrower and the Guarantors now owned or hereafter acquired incidental to such Mortgaged Properties and (iii) all of the issued and outstanding Equity Interests of each Guarantor. 

(b) Additional Collateral. In connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report
and the list of current Mortgaged Properties to ascertain whether the Mortgaged Properties represent at least 80% of the PV-9 of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration
and production activities, acquisitions, dispositions and production. In the 

  
 -72- 

 
event that the Mortgaged Properties do not represent at least 80% of such PV-9, then the Borrower shall, and shall cause its Subsidiaries to, grant, within thirty (30) days of delivery of
the certificate required under Section 8.07(c), to the Administrative Agent as security for the Obligations a first-priority Lien on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after
giving effect thereto, the Mortgaged Properties will represent at least 80% of such PV-9. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, security agreements and financing statements or other
Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the
foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a Guarantor, and its Equity Interests shall be pledged as contemplated by Section 8.08(a). In connection with
the foregoing, the Borrower agrees to execute and deliver such other additional closing documents, certificates and legal opinions as shall reasonably be requested by the Administrative Agent. 

(c) Legal Opinions. Promptly after the filing of any new Security Instrument in any state, upon the request of the Administrative Agent,
the Borrower will provide to the Administrative Agent an opinion addressed to the Administrative Agent for the benefit of the Lenders in form and substance satisfactory to the Administrative Agent, from counsel acceptable to Administrative Agent,

Instruments.

the ERISA Affiliate is taking or proposes to take with respect thereto, and, when known, any action taken or proposed by the Internal Revenue Service, the Department of Labor or the PBGC with respect thereto, and (iii) immediately upon receipt
thereof, copies of any notice of the PBGC’s intention to terminate or to have a trustee appointed to administer any Plan. With respect to each Plan (other than a Multiemployer Plan), the Borrower will, and will cause each Subsidiary and ERISA
Affiliate to, (i) satisfy in full and in a timely manner, without incurring any late payment or underpayment charge or penalty and without giving rise to any lien, all of the contribution and funding requirements of Section 412 of the Code
(determined without regard to subsections (d), (e), (f) and (k) thereof) and of Section 302 of ERISA (determined without regard to sections 303, 304 and 306 of ERISA), and (ii) pay, or cause to be paid, to the PBGC in a

Property or any part thereof or other Property which the Borrower or any Subsidiary intends to use for substantially the same purpose or purposes as the Property sold or transferred.

of its business as an oil and gas exploration and production company. 
 Section 9.07 Limitation on Leases. Neither the Borrower

lease agreements to exceed $10,000,000.00 in any period of twelve (12) consecutive calendar months during the life of such leases. 

Section 9.08 Mergers. Except for the Merger, neither the Borrower nor any Subsidiary will merge into or with or consolidate with

case as now in effect or as the same may hereinafter be in effect.

reasonably be expected to have a Material Adverse Effect, the Borrower will not at any time: 
 (a) Engage in, or permit any Subsidiary or
ERISA Affiliate to engage in, any transaction in connection with which the Borrower, any Subsidiary or any ERISA Affiliate could be subjected to either a civil penalty assessed pursuant to Section 502(c), (i) or (l) of ERISA or a tax

 -78- 

 
maintained, or contributed to, (1) any Multiemployer Plan, or (2) any other Plan that is subject to Title IV of ERISA under which the actuarial present value of the benefit
liabilities under such Plan exceeds the current value of the assets (computed on a plan termination basis in accordance with Title IV of ERISA) of such Plan allocable to such benefit liabilities; 

(h) Incur, or permit any Subsidiary or ERISA Affiliate to incur, a liability to or on account of a Plan under sections 515, 4062, 4063,

that may not be terminated by such entities in their sole discretion at any time without any material liability; or 
 (j) Amend or permit
any Subsidiary or ERISA Affiliate to amend, a Plan resulting in an increase in current liability such that the Borrower, any Subsidiary or any ERISA Affiliate is required to provide security to such Plan under Section 401(a)(29) of the Code.

to 1.00 at any time such ratio is tested. The Current Ratio shall be calculated and tested quarterly as of the last day of each fiscal quarter of Borrower. “Current Assets” shall have the meaning of such term as defined by GAAP, except any
availability under the Borrowing Base shall be included in the definition of Current Assets; and “Current Liabilities” shall have the meaning of such term as defined by GAAP, except that current maturities of Obligations under this
Agreement shall be excluded. Current asset or liability accounts associated with Hedge Agreements will be excluded from calculations of Current Assets and Current Liabilities. 

Section 9.13 Leverage Ratio. The Borrower will not permit its Leverage Ratio as of the end of any fiscal quarter of the Borrower
(calculated quarterly at the end of each fiscal quarter) to be greater than 3.50 to 1.00 commencing with the fiscal quarter ending December 31, 2013. For the purposes of this Section 9.13, “Leverage Ratio” shall
mean the ratio of (i) total Debt of the type described in clauses (i) and (ii) of the definition thereof as of such date of the Borrower and its Consolidated Subsidiaries, to (ii) EBITDAX of the Borrower and its Consolidated
Subsidiaries for the four fiscal quarters ending on such date. 
 Section 9.14 Sale of Borrowing Base Properties. The Borrower
will not, and will not permit any Subsidiary to, sell, assign, convey or otherwise transfer any Borrowing Base Property or any interest in any Borrowing Base Property, except for Borrowing Base Property for which the Borrower has given the
Administrative Agent a Notice of Transfer and, if applicable, the information described in the last sentence of this Section 9.14. If 65% of the PV-9 attributable to such Borrowing Base Property (and any
associated Hedge Agreement that is 

  
 -79- 

 
terminated or modified in connection with such sale, assignment, conveyance or transfer), when aggregated with 65% of the PV-9 attributable to all other Borrowing Base Property sold, assigned,
conveyed or transferred (and any associated Hedge Agreement that is terminated or modified in connection with such sale(s), assignment(s), conveyance(s) or transfer(s)) since the most recent Redetermination Date, exceeds five percent (5%) of
the then existing Borrowing Base (as determined by the Administrative Agent) in the aggregate in between any two consecutive Redetermination Dates, the Administrative Agent and the Required Lenders shall have the right to adjust the Borrowing Base
to reflect such sale, assignment, conveyance or transfer. In the event of a sale, assignment, conveyance or transfer of sufficient Borrowing Base Properties to allow the Administrative Agent and the Required Lenders to adjust the Borrowing Base as
provided in the preceding sentence, the Borrower shall deliver to the Administrative Agent at the same time as, or promptly following the delivery of the Notice of Transfer with respect thereto an update of the most recent Reserve Report reflecting
the exclusion of such Borrowing Base Properties as have been or will be sold, assigned, conveyed or transferred. 
 Section 9.15
Environmental Matters. Neither the Borrower nor any Subsidiary will cause or permit any of its Property to be in violation of, or do anything or permit anything to be done which will cause from any Property any actual, alleged or threatened
discharge, dispersal, release, escape, emission, transportation, disposal, seepage, exposure, consumption, or contact (collectively, “Releases”) of, with, to, or from any hazardous substance under any Environmental Laws,
subject any Property to any enforcement action under any Environmental Laws by any Governmental Authority or lawsuit at any Property relating to hazardous substances, or subject any such Property to any remedial obligations by any Governmental
Authority under any Environmental Laws, assuming disclosure to the applicable Governmental Authority of all relevant facts, conditions and circumstances, if any, pertaining to such Property where such Releases, violations or remedial obligations
would have a Material Adverse Effect. 
 Section 9.16 Transactions with Affiliates. Neither the Borrower nor any Subsidiary will
enter into any transaction, including, without limitation, any purchase, sale, lease or exchange of Property or the rendering of any service, with any Affiliate (other than the Borrower or a Subsidiary of the Borrower) unless such transactions are
otherwise permitted under this Agreement, are in the ordinary course of its business and are upon fair and reasonable terms no less favorable to it than it would obtain in a comparable arm’s length transaction with a Person not an Affiliate.

 Section 9.17 Negative Pledge Agreements. Neither the Borrower nor any Subsidiary will create, incur, assume or permit to
exist any contract, agreement or understanding which in any way prohibits or restricts the granting, conveying, creation or imposition of any Lien on any of its Property in favor of the Administrative Agent and/or the Beneficiaries or restricts any
Subsidiary from paying dividends to the Borrower, or which requires the consent of or notice to other Persons in connection therewith, except such restrictions in favor of the holders of Debt secured by Liens described in Sections 9.01(d) and
9.01(e), but only insofar as such restrictions pertain to the Property encumbered thereby. 

  
 -80- 

 Section 9.18 Take-or-Pay or Other Prepayments. The Borrower will not enter into any
take-or-pay agreements with respect to the Oil and Gas Properties of the Borrower, any of its Subsidiaries, or any Guarantor which would require the Borrower, any of its Subsidiaries or any Guarantor to deliver Hydrocarbons produced from its Oil and
Gas Properties at some future time without then or thereafter receiving full payment therefor in an amount which would result in the failure of the representation and warranty set forth in Section 7.23 to be true and correct at all times. 

Section 9.19 Limitation on Hedging. The total notional volume attributable to any Hedge Agreement with respect to Hydrocarbon
Interests of the Borrower and its Subsidiaries shall not at any time on a rolling basis exceed the greater of (a) for the twenty-four (24) month period following any date of determination, ninety percent (90%) of reasonably
anticipated projected production from proved developed producing Hydrocarbon Interests as of the most recent Reserve Report in any period and (b) for the sixty (60) month period following any date of determination, eighty five percent
(85%) of reasonably anticipated projected production from such proved, developed producing Hydrocarbon Interests as of the most recent Reserve Report. If the Hedge Agreement is an interest rate hedge, the notional principal amount shall not
exceed more than seventy-five percent (75%) of the sum of Loans plus the aggregate outstanding principal amount of the Senior Unsecured Notes. Notwithstanding the foregoing, during the period from August to October of each calendar
year, the Borrower and its Subsidiaries shall not enter into or maintain any commodity hedging transactions with respect to offshore Oil and Gas Properties other than floors, puts or other hedging arrangements that do not carry any delivery risk.
All Hedge Agreements will be with Approved Counterparties.

collateral to secure the LC Exposure as provided in Section 2.01(j)) to be forthwith due and payable, whereupon such amounts shall be immediately due and payable without presentment, demand, protest, notice of intent to accelerate, notice of

 ARTICLE XI 

THE ADMINISTRATIVE AGENT 

Section 11.01 Appointment, Powers and Immunities. Each Lender hereby irrevocably appoints and authorizes the Administrative Agent
to act as its Administrative Agent hereunder and under the Security Instruments with such powers as are specifically delegated to the Administrative Agent by the terms of this Agreement and the Security Instruments, together with such other powers
as are reasonably incidental thereto. The Administrative Agent (which term as used in this sentence and in Section 11.05 and the first sentence of Section 11.06 shall include reference to its Affiliates and its and its Affiliates’
officers, directors, employees, attorneys, accountants, experts and agents): (i) shall have no duties or responsibilities except those expressly set forth in the Loan Documents, and shall not by reason of the Loan Documents be a trustee or
fiduciary for any Lender; (ii) makes no representation or warranty to any Lender and shall not be responsible to the Lenders for any recitals, statements, representations or warranties contained in this Agreement, or in any certificate or other
document referred to or provided for in, or received by any of them under, this Agreement, or for the value, validity, effectiveness, genuineness, execution, effectiveness, legality, enforceability or sufficiency of this Agreement, any Note or any
other document referred to or provided for herein or for any failure by the Borrower or any other Person (other than the Administrative Agent) to perform any of its obligations hereunder or thereunder or for the existence, value, perfection or
priority of any collateral security or the financial or other condition of the Borrower, its Subsidiaries or any other obligor or guarantor; (iii) except pursuant to Section 11.07 shall not be required to initiate or conduct any litigation
or collection proceedings hereunder; and (iv) shall not be responsible for any action taken or omitted to be taken by it hereunder or under any other document or instrument referred to or provided for herein or in connection herewith including
its own ordinary negligence, except for its own gross negligence or willful misconduct. The Administrative Agent may employ agents, accountants, attorneys and experts and shall not be responsible for the negligence or misconduct of any such agents,
accountants, attorneys or experts selected by it in good faith or any action taken or omitted to be taken in good faith by it in accordance with the advice of such agents, accountants, attorneys or experts. The

  
 -84- 

 
Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted
hereunder shall have been filed with the Administrative Agent. The Administrative Agent is authorized to release any collateral, or subordinate any Lien on any collateral, that is permitted to be sold or otherwise disposed of or released pursuant to
the terms of the Loan Documents. 
 Section 11.02 Reliance by Administrative Agent. The Administrative Agent shall be entitled
to rely upon any certification, notice or other communication (including any thereof by telephone, telecopier, telegram or cable) believed by it to be genuine and correct and to have been signed or sent by or on behalf of the proper Person or
Persons, and upon advice and statements of legal counsel, independent accountants and other experts selected by the Administrative Agent. 

Section 11.03 Defaults. The Administrative Agent shall not be deemed to have knowledge of the occurrence of a Default (other than
the non-payment of principal of or interest on Loans or of fees or failure to reimburse for Letter of Credit drawings) unless the Administrative Agent has received notice from a Lender or the Borrower specifying such Default and stating that such
notice is a “Notice of Default.” In the event that the Administrative Agent receives such a notice of the occurrence of a Default, the Administrative Agent shall give prompt notice thereof to the Lenders. In the event of a payment Default,
the Administrative Agent shall give each Lender prompt notice of each such payment Default. 
 Section 11.04 Rights as a Lender.
With respect to its Commitments and the Loans made by it and its participation in the issuance of Letters of Credit, RBC (and any successor acting as Administrative Agent) in its capacity as a Lender or Amegy, as the Swing Line Lender hereunder
shall have the same rights and powers hereunder as any other Lender and may exercise the same as though it were not acting as the Administrative Agent, and the term “Lender” or “Lenders” shall, unless
the context otherwise indicates, include the Administrative Agent in its individual capacity. Each of RBC (and any successor acting as Administrative Agent), Amegy (and any successor acting as the Swing Line Lender) and each of their respective
Affiliates may (without having to account therefor to any Lender) accept deposits from, lend money to and generally engage in any kind of banking, trust or other business with the Borrower (and any of its Affiliates) as if it were not acting as the
Administrative Agent or the Swing Line Lender, as applicable, and each of RBC, Amegy and each of their respective Affiliates may accept fees and other consideration from the Borrower for services in connection with this Agreement or otherwise
without having to account for the same to the Lenders. 
 Section 11.05 Indemnification. The Lenders agree to indemnify the
Administrative Agent, the Swing Line Lender and the Issuing Bank ratably in accordance with their Percentage Shares for the Indemnity Matters as described in Section 12.03 to the extent not indemnified or reimbursed by the Borrower under
Section 12.03, but without limiting the obligations of the Borrower under said Section 12.03 and for any and all other liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind and nature whatsoever which may be imposed on, incurred by or asserted against the Administrative Agent, the Swing Line Lender or the Issuing Bank in any way relating to or arising out of: (i) this Agreement, the Security Instruments or
any other documents contemplated by or referred to herein or the transactions contemplated hereby, but 

  
 -85- 

 
excluding, unless a Default has occurred and is continuing, normal administrative costs and expenses incident to the performance of its agency duties hereunder or (ii) the enforcement of any
of the terms of this Agreement, any Security Instrument or of any such other documents; whether or not any of the foregoing specified in this Section 11.05 arises from the sole or concurrent negligence of the Administrative Agent, the Swing
Line Lender or the Issuing Bank, provided that no Lender shall be liable for any of the foregoing to the extent they arise from the gross negligence or willful misconduct of the Administrative Agent as determined by a final nonappealable judgment of
a court of competent jurisdiction. 
 Section 11.06 Non-Reliance on Administrative Agent and Other Lenders. Each Lender
acknowledges and agrees that it has, independently and without reliance on the Administrative Agent, the Swing Line Lender or any other Lender, and based on such documents and information as it has deemed appropriate, made its own credit analysis of
the Borrower and its decision to enter into this Agreement, and that it will, independently and without reliance upon the Administrative Agent, the Swing Line Lender or any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions in taking or not taking action under this Agreement. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Borrower
of this Agreement, the Notes, the Security Instruments or any other document referred to or provided for herein or to inspect the properties or books of the Borrower. Except for notices, reports and other documents and information expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, the Administrative Agent shall not have any duty or responsibility to provide any Lender with any credit or other information concerning the affairs, financial condition or
business of the Borrower (or any of its Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard, each Lender acknowledges that Cadwalader, Wickersham & Taft LLP is acting in this
transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each Lender will consult with its own legal counsel to the extent that it deems necessary in
connection with the Loan Documents and the matters contemplated therein. 
 Section 11.07 Action by Administrative Agent. Except
for action or other matters expressly required of the Administrative Agent hereunder, the Administrative Agent shall in all cases be fully justified in failing or refusing to act hereunder unless it shall (i) receive written instructions from
the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) specifying the action to be taken, and (ii) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be
incurred by it by reason of taking or continuing to take any such action. The instructions of the Majority Lenders (or all of the Lenders as expressly required by Section 12.04) and any action taken or failure to act pursuant thereto by the
Administrative Agent shall be binding on all of the Lenders. If a Default has occurred and is continuing, the Administrative Agent shall take such action with respect to such Default as shall be directed by the Majority Lenders (or all of the
Lenders as required by Section 12.04) in the written instructions (with indemnities) described in this Section 11.07, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent
may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required
to take any action which exposes the Administrative Agent to personal liability or which is contrary to this Agreement and the Security Instruments or applicable law. 

  
 -86- 

 Section 11.08 Resignation of Administrative Agent. Subject to the appointment and
acceptance of a successor Administrative Agent as provided below, the Administrative Agent may resign at any time by giving notice thereof to the Lenders and the Borrower. Upon any such resignation, the Majority Lenders shall have the right to
appoint a successor Administrative Agent. If no successor Administrative Agent shall have been so appointed by the Majority Lenders and shall have accepted such appointment within thirty (30) days after the retiring Administrative Agent’s
giving of notice of resignation, then the Lenders as a group shall act as Administrative Agent until a successor Administrative Agent is appointed by the Majority Lenders. Upon the acceptance of such appointment hereunder by a successor
Administrative Agent, such successor Administrative Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative Agent’s resignation hereunder as Administrative Agent, the provisions of this Article XI and Section 12.03 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as the Administrative Agent. Any resignation by RBC as Administrative Agent pursuant to this Section shall also constitute its resignation as Issuing Bank. Upon the
acceptance of a successor’s appointment as Administrative Agent hereunder, (i) such successor shall succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Issuing Bank, (ii) the retiring
Issuing Bank shall be discharged from all of its respective duties and obligations hereunder or under the other Loan Documents, and (iii) the successor Issuing Bank shall issue letters of credit in substitution for the Letters of Credit, if
any, outstanding at the time of such succession or make other arrangements satisfactory to the retiring Issuing Bank to effectively assume the obligations of the retiring Issuing Bank with respect to such Letters of Credit. If upon such resignation
by the Administrative Agent there are no Majority Lenders (i) because all of the Loans have been repaid, (ii) the LC Exposure extinguished, and (iii) the Commitments terminated, but Obligations remain under the Hedge Agreements that
are secured by the Security Instruments, such appointment of a successor shall be made by the then current Administrative Agent if it is a counterparty under a Hedge Agreement and if it is not, such appointment shall be made by the Secured Swap
Providers holding more than 50% of the Obligations in respect of Hedge Agreements on the date of such Administrative Agent’s resignation notice. 

Section 11.09 Resignation of Swing Line Lender. The Swing Line Lender may resign at any time by giving thirty (30) days’
prior notice to the Administrative Agent, the Lenders and the Borrower. After the resignation of the Swing Line Lender hereunder, the retiring Swing Line Lender shall remain a party hereto and shall continue to have all the rights and obligations of
a Swing Line Lender under this Agreement and the other Loan Documents with respect to Swing Line Loans made by it prior to such resignation, but shall not be required to make any additional Swing Line Loans. 

Section 11.10 Other Agents; Lead Managers. None of the Lenders or other Persons identified on the facing page or signature pages
of this Agreement as a “syndication agent,” “documentation agent,” “Arranger,” “co-agent,” “bookrunner” or “lead manager” shall have any right, power, obligation, liability, responsibility
or duty under this Agreement as such. 

  
 -87- 

 
Without limiting the foregoing, none of the Lenders or other Persons so identified shall have or be deemed to have any fiduciary relationship with Administrative Agent or any Lender. Each Lender
acknowledges that it has not relied, and will not rely, on any of the Lenders or other Persons so identified in deciding to enter into this Agreement or in taking or not taking action hereunder. 

Section 11.11 Hedging Arrangements. To the extent any Lender Affiliate is a party to a Hedge Agreement with Borrower or any
Guarantor, such Affiliate shall be deemed to appoint the Administrative Agent its nominee and agent, and to act for and on behalf of such Affiliate in connection with the Security Instruments and to be bound by this Article XI. 

Section 11.12 Filing of Proofs of Claim. In case of any Default under Section 10.01(e), Section 10.01(f) or
Section 10.01(g), the Administrative Agent (regardless of whether the principal of any Loan or LC Exposure shall then be due and payable and regardless of whether the Administrative Agent has made any demand on the Borrower) shall be entitled
and empowered, by intervention in such proceeding or otherwise: 
 (a) to (i) file and prove a claim for the whole
amount of the principal and interest owing and unpaid in respect of the Loans, LC Exposure and all other Obligations that is owing and unpaid and (ii) file such other documents as may be necessary or advisable in order to have the claims of the
Lenders and the Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders, the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders
and the Administrative Agent under Section 2.04 and Section 12.03) allowed in such judicial proceeding; and 
 (b)
to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same. 
 Each Lender
hereby authorizes any custodian, receiver, assignee, trustee, conservator, sequestrator or other similar official in any such judicial proceeding: (i) to make such payments to the Administrative Agent; and (ii) if the Administrative Agent
shall consent to the making of such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and
any other amounts due the Administrative Agent under Section 2.04 and Section 12.03. Nothing contained herein shall be deemed to authorize the Administrative Agent to authorize or consent to or accept or adopt on behalf of any Lender any
plan of reorganization, arrangement, adjustment or composition affecting the Obligations or the rights of any Lender or to authorize the Administrative Agent to vote in respect of the claim of any Lender in any such proceeding. Each Lender retains
its right to file and prove a claim separately. 
 Section 11.13 Collateral. Each Lender, the Swing Line Lender and the Issuing
Bank each hereby authorizes the Administrative Agent to release any collateral that is permitted to be sold or released pursuant to the terms hereof or of the other Loan Documents. Each Lender, the Issuing Bank and the Swing Line Lender hereby
authorize the Administrative Agent to execute and deliver to the Borrower (or its designee), at the Borrower’s sole cost and expense, 

  
 -88- 

 
any and all releases of Liens, termination statements, assignments, subordinations or other documents reasonably requested by the Borrower in connection with any such sale or other disposition of
assets to the extent such sale or other disposition is permitted by the terms of this Agreement or is otherwise authorized by the terms of the Loan Documents or to acknowledge and agree to Excepted Liens, as applicable. 

ARTICLE XII

Section 12.01 Waiver. No failure on the part of the Administrative Agent or any Lender to exercise and no delay in exercising, and
no course of dealing with respect to, any right, power or privilege under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under any of the Loan Documents preclude

gross negligence or willful misconduct on the part of the Indemnified Party or any of its Affiliates or any of their respective officers, directors, employees, representatives, agents, attorneys, accountants or experts, as determined by a final

 -90- 

 (b) No Indemnified Party may settle any claim to be indemnified without the consent of the
indemnitor, such consent not to be unreasonably withheld; provided, that the indemnitor may not reasonably withhold consent to any settlement that an Indemnified Party proposes, if the indemnitor does not have the financial ability to pay all
its obligations outstanding and asserted against the indemnitor at that time, including the maximum potential claims against the Indemnified Party to be indemnified pursuant to this Section 12.03. 

(c) In the case of any indemnification hereunder, the Administrative Agent or Lender, as appropriate shall give notice to the Borrower of any
such claim or demand being made against the Indemnified Party. 
 (d) The foregoing indemnities shall extend to the Indemnified Parties

(second) of torts of one or more of the Indemnified Parties or by reason of strict liability imposed without fault on any one or more of the Indemnified Parties; provided, however, that to the extent that an Indemnified Party is found to have
committed an act of gross negligence or willful misconduct, this contractual obligation of indemnification shall continue but shall only extend to the portion of the claim that is deemed to have occurred by reason of events other than the gross
negligence or willful misconduct of the Indemnified Party as determined by a final nonappealable judgment of a court of competent jurisdiction. 

(e) The Borrower’s obligations under this Section 12.03 shall survive any termination of this Agreement and the payment of the Notes

 (f) The Borrower shall pay any amounts due under this Section 12.03 within
thirty (30) days of the receipt by the Borrower of notice of the amount due. 
 (g) Waiver of Consequential Damages. To the fullest
extent permitted by applicable law, no party to this Agreement shall assert, and each hereby waives, and acknowledges that no other Person shall have, any claim against any party or Indemnified Party, on any theory of liability, for special,
indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby, the transactions
contemplated hereby or thereby, any Loan or Letter of Credit or the use of the proceeds thereof. 
 Section 12.04 Amendments,
etc. Any provision of this Agreement or any Security Instrument may be amended, modified or waived with the Borrower’s and the Majority Lenders’ prior written consent; provided that (i) no amendment, modification or waiver
which extends the final maturity of the Loans, forgives the principal amount of any Obligations reduces the interest rate applicable to the Loans or the fees payable to the Lenders generally shall be effective without the consent of each Lender
adversely affected thereby, (ii) no amendment, 

  
 -91- 

 
modification or waiver which increases the Borrowing Base, affects Section 2.03(a), 4.05, this Section 12.04 or Section 12.06(a), releases any Guarantor (except as expressly
contemplated herein) or all or substantially all the collateral or modifies the definitions of “Majority Lenders” or “Required Lenders” shall be effective without consent of all Lenders (other than Defaulting Lenders, and other

the consent of the Administrative Agent, the Swing Line Lender or the Issuing Bank, as applicable 
 Section 12.05 Successors and
Assigns. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. 

Section 12.06 Assignments and Participations. (a) The provisions of this Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns permitted hereby, except that the Borrower may not assign its rights or obligations hereunder or under the Notes or any Letters of Credit without the prior consent of all of
the Lenders and the Administrative Agent, and no Lender may assign or otherwise transfer any of its rights or obligations hereunder except (i) to an assignee in accordance with the provisions of paragraph (b) of this Section, (ii) by
way of participation in accordance with the provisions of paragraph (d) of this Section, or (iii) by way of pledge or assignment of a security interest subject to the restrictions of paragraph (f) of this Section (and any other
attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns
permitted hereby, Participants to the extent provided in paragraph (d) of this Section and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent and the Lenders) any legal or equitable right,
remedy or claim under or by reason of this Agreement. 
 (b) Assignments by Lenders. Any Lender may at any time assign to one or more
assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) pursuant to an Assignment and Assumption substantially in the form of
Exhibit E (an “Assignment”); provided that any such assignment shall be subject to the following conditions: 

(i) Minimum Amounts. In all cases, the aggregate amount of the Commitment (which for this purpose includes Loans
outstanding thereunder) or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with
respect to such assignment is delivered to the Administrative Agent or, if “Trade Date” is specified in the Assignment and Assumption, as of the Trade Date) shall not be less than $5,000,000.00, unless each of the Administrative Agent and,
so long as no Default or Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed). 

  
 -92- 

 (ii) Proportionate Amounts. Each partial assignment shall be made as an
assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned. 

(iii) Required Consents. No consent shall be required for any assignment except to the extent required by
paragraph (b)(i) of this Section and, in addition: 
 (A) the consent of the Borrower (such consent not to be
unreasonably withheld or delayed) shall be required unless (x) a Default or Event of Default has occurred and is continuing at the time of such assignment, or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved
Fund; provided that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within five (5) Business Days after having received notice thereof; 

(B) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required if such
assignment is to a Person that is not a Lender with a Commitment, an Affiliate of such Lender or an Approved Fund with respect to such Lender; 

and 
 (C) the
consent of the Issuing Bank. 
 (iv) Assignment and Assumption. The parties to each assignment shall execute and
deliver to the Administrative Agent an Assignment, together with a processing and recordation fee of $3,500.00; provided that the Administrative Agent may, in its sole discretion, elect to waive such processing and recordation fee in the case
of any assignment. The assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire. 

(v) No Assignment to Certain Persons. No such assignment shall be made to (A) the Borrower or any of the
Borrower’s Affiliates or Subsidiaries or (B) to any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (B). 

(vi) No Assignment to Natural Persons. No such assignment shall be made to a natural Person. 

(vii) Certain Additional Payments. In connection with any assignment of rights and obligations of any Defaulting Lender
hereunder, no such assignment shall be effective unless and until, in addition to the other conditions thereto set forth herein, the parties to the assignment shall make such additional payments to the Administrative Agent in an aggregate amount
sufficient, upon distribution thereof as appropriate (which may be outright payment, purchases by the assignee of participations or 

  
 -93- 

 
subparticipations, or other compensating actions, including funding, with the consent of the Borrower and the Administrative Agent, the applicable pro rata share of Loans previously requested but
not funded by the Defaulting Lender, to each of which the applicable assignee and assignor hereby irrevocably consent), to (x) pay and satisfy in full all payment liabilities then owed by such Defaulting Lender to the Administrative Agent, the
Issuing Bank and each other Lender hereunder (and interest accrued thereon), and (y) acquire (and fund as appropriate) its full pro rata share of all Loans and participations in Letters of Credit in accordance with its Percentage Share.
Notwithstanding the foregoing, in the event that any assignment of rights and obligations of any Defaulting Lender hereunder shall become effective under applicable law without compliance with the provisions of this paragraph, then the assignee of
such interest shall be deemed to be a Defaulting Lender for all purposes of this Agreement until such compliance occurs. 
 Subject to acceptance and
recording thereof by the Administrative Agent pursuant to paragraph (c) of this Section, from and after the effective date specified in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the
extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption,
be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall
continue to be entitled to the benefits of Section 11.05 with respect to facts and circumstances occurring prior to the effective date of such assignment; provided, that except to the extent otherwise expressly agreed by the affected
parties, no assignment by a Defaulting Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. Any assignment or transfer by a Lender of rights or obligations
under this Agreement that does not comply with this paragraph shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with paragraph (d) of this Section. 

(c) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices
in the United States a copy of each Assignment delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and stated interest) of the Loans (other than the Swing Line
Loans) owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders
shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable
time and from time to time upon reasonable prior notice. 
 (d) Participations. Any Lender may at any time, without the consent of, or
notice to, the Borrower or the Administrative Agent, sell participations to any Person (other than a natural Person or the Borrower or any of the Borrower’s Affiliates or Subsidiaries) (each, a “Participant”) in all or a
portion of such Lender’s rights and/or obligations under this Agreement (including all or a portion of its Commitment and/or the Loans owing to it); provided that 

  
 -94- 

 
(i) such Lender’s obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties hereto for the performance of such
obligations, and (iii) the Borrower, the Administrative Agent, the Issuing Bank and Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. For the
avoidance of doubt, each Lender shall be responsible for the indemnity under Section 11.05 with respect to any payments made by such Lender to its Participant(s). 

Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right
to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree
to any amendment, modification or waiver (i) described in Section 2.08(b) that affects such Participant, (ii) that increases or extends the Commitment applicable to such Participant, (iii) that reduces the interest rate or
principal amount applicable to such Participant or (iv) that extends the final maturity of the Loans in which such Participant participates. The Borrower agrees that each Participant shall be entitled to the benefits of Sections 4.06, 5.01
and 5.06(d) (subject to the requirements and limitations therein, including the requirements under Section 4.06(d) (it being understood that the documentation required under Section 4.06(d) shall be delivered to the participating Lender))
to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to paragraph (b) of this Section; provided that such Participant (A) agrees to be subject to the provisions of Section 5.06 as if it
were an assignee under paragraph (b) of this Section; and (B) shall not be entitled to receive any greater payment under Sections 4.06 and 5.01, with respect to any participation, than its participating Lender would have been entitled
to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the
Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 5.06 with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled
to the benefits of Section 4.05 as though it were a Lender; provided that such Participant agrees to be subject to the obligations of Section 4.05 as though it were a Lender. Each Lender that sells a Participation shall, acting
solely for this purpose as a nonfiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or
other obligations under the Loan Documents (the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register (including the identity of any
Participant or any information relating to a Participant’s interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish
that such commitment, loan, letter of credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and
such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative
Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register. 

  
 -95- 

 (e) Certain Pledges. Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank or other central banking authority; provided that no such pledge or
assignment shall release such Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 

(f) Notwithstanding any other provisions of this Section 12.06, no transfer or assignment of the interests or obligations of any Lender or
any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Borrower to file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state. 

Section 12.07 Invalidity. In the event that any one or more of the provisions contained in any of the Loan Documents or the
Letters of Credit, the Letter of Credit Agreements shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of the Notes, this Agreement or
any other Loan Document. 
 Section 12.08 Counterparts; Integration; Effectiveness. This Agreement may be executed in
counterparts (and by different parties hereto in different counterparts), each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement and the other Loan Documents, and any
separate letter agreements with respect to fees payable to the Administrative Agent, constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or
written, relating to the subject matter hereof. Except as provided in Section 6.01, this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received
counterparts hereof that, when taken together, bear the signatures of each of the other parties hereto. Delivery of an executed counterpart of a signature page of this Agreement by facsimile or in electronic (i.e., “pdf” or
“tif”) format shall be effective as delivery of a manually executed counterpart of this Agreement. 
 Section 12.09
Electronic Execution of Assignments. The words “execution,” “signed,” “signature,” and words of like import in any Assignment shall be deemed to include electronic signatures or the keeping of records in
electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature or the use of a paper-based recordkeeping system, as the case may be, to the extent and as provided for in any applicable
law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act, or any other similar state laws based on the Uniform Electronic Transactions Act. 

Section 12.10 Survival. The obligations of the parties under Section 4.06, Article V, and Sections 11.05, 12.03,
and 12.15 shall survive the repayment of the Loans and the termination of the Commitments. To the extent that any payments on the Obligations or proceeds of any collateral are subsequently invalidated, declared to be fraudulent or preferential, set
aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under 

  
 -96- 

 
any bankruptcy law, common law or equitable cause, then to such extent, the Obligations so satisfied shall be revived and continue as if such payment or proceeds had not been received and the
Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Security Instrument shall continue in full force and effect. In such event, each Security Instrument shall be
automatically reinstated and the Borrower shall and shall cause its Subsidiaries take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such reinstatement. 

Section 12.11 Captions. Captions and Section headings appearing herein are included solely for convenience of reference and are
not intended to affect the interpretation of any provision of this Agreement. 
 Section 12.12 No Oral Agreements. THE LOAN
DOCUMENTS EMBODY THE ENTIRE AGREEMENT AND UNDERSTANDING BETWEEN THE PARTIES AND SUPERSEDE ALL OTHER AGREEMENTS AND UNDERSTANDINGS BETWEEN SUCH PARTIES RELATING TO THE SUBJECT MATTER HEREOF AND THEREOF. THE 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 12.13 Governing Law; Submission to Jurisdiction. (a) This Agreement and the other Loan Documents and any claims,
controversy, dispute or cause of action (whether in contract or tort or otherwise) based upon, arising out of or relating to this Agreement or any other Loan Document (except, as to any other Loan Document, as expressly set forth therein) and the
transactions contemplated hereby and thereby shall be governed by, and construed in accordance with, the law of the State of New York. 
 (b)
The Borrower irrevocably and unconditionally agrees that it will not commence any action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Administrative Agent,
any Lender, the Issuing Bank, or any Related Party of the foregoing in any way relating to this Agreement or any other Loan Document or the transactions relating hereto or thereto, in any forum other than the courts of the State of New York sitting
in New York County, and of the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and
agrees that all claims in respect of any such action, litigation or proceeding may be heard and determined in such New York State court or, to the fullest extent permitted by applicable law, in such federal court. Each of the parties hereto agrees
that a final judgment in any such action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Nothing in this Agreement or in any other Loan Document
shall affect any right that the Administrative Agent, any Lender or the Issuing Bank may otherwise have to bring any action or proceeding relating to this Agreement or any other Loan Document against the Borrower or its properties in the courts of
any jurisdiction. 

  
 -97- 

 (c) Each party hereto irrevocably consents to service of process in the manner provided for
notices in Section 12.02. Nothing in this Agreement will affect the right of any party hereto to serve process in any other manner permitted by applicable law. 

(d) EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN
ANY LEGAL PROCEEDING DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY). EACH PARTY HERETO
(A) CERTIFIES THAT NO REPRESENTATIVE, ADMINISTRATIVE AGENT OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND
(B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION. 

(e) Each party hereto irrevocably and unconditionally waives, to the fullest extent permitted by applicable law, any objection that it may now
or hereafter have to the laying of venue of any action or proceeding arising out of or relating to this Agreement or any other Loan Document in any court referred to in paragraph (b) of this Section. Each of the parties hereto hereby
irrevocably waives, to the fullest extent permitted by applicable law, the defense of an inconvenient forum to the maintenance of such action or proceeding in any such court. 

Section 12.14 Interest. It is the intention of the parties hereto that each Lender shall conform strictly to usury laws applicable
to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of New York or any other jurisdiction whose laws may be
mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection with or as security
for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under any of the Loan
Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be credited by such
Lender on the principal amount of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such 

  
 -98- 

 
Lender to the Borrower); and (ii) in the event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this
Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid, shall be credited by such Lender on the principal amount
of the Obligations (or, to the extent that the principal amount of the Obligations shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid or agreed to be paid to any Lender for the use, forbearance
or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the full term of the Loans evidenced by the Notes until payment in full so that the rate or
amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of interest payable to any Lender on any date shall be computed at the
Highest Lawful Rate applicable to such Lender pursuant to this Section 12.14 and (ii) in respect of any subsequent interest computation period the amount of interest otherwise payable to such Lender would be less than the amount of
interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent interest computation period shall continue to be computed at the Highest
Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such Lender if the total amount of interest had been computed without giving
effect to this Section 12.14. 
 Section 12.15 Confidentiality. Each of the Administrative Agent, the Lenders and the
Issuing Bank agree to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its Affiliates and to its Related Parties (it being understood that the Persons to whom such disclosure is
made will be informed of the confidential nature of such Information and instructed to keep such Information confidential); (b) to the extent required or requested by any regulatory authority purporting to have jurisdiction over such Person or
its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners); (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process; (d) to
any other party hereto; (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or
thereunder; (f) subject to an agreement containing provisions substantially the same as those of this Section, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights and obligations
under this Agreement, or (ii) any actual or prospective party (or its Related Parties) to any swap, derivative or other transaction under which payments are to be made by reference to the Borrower and its obligations, this Agreement or payments
hereunder; (g) on a confidential basis to (i) any rating agency in connection with rating the Borrower or its Subsidiaries or (ii) the CUSIP Service Bureau or any similar agency in connection with the issuance and monitoring of CUSIP
numbers; (h) with the consent of the Borrower; or (i) to the extent such Information (x) becomes publicly available other than as a result of a breach of this Section, or (y) becomes available to the Administrative Agent, any
Lender, the Issuing Bank or any of their respective Affiliates on a nonconfidential basis from a source other than the Borrower. 
 For
purposes of this Section, “Information” shall mean all information received from the Borrower or any of its Subsidiaries relating to the Borrower or any of its Subsidiaries or any of their respective businesses, other than
any such information that is available to the Administrative Agent, any Lender or the Issuing Bank on a nonconfidential basis prior to disclosure by the Borrower or any of its Subsidiaries; provided that, in the case of information

  
 -99- 

 
received from the Borrower or any of its Subsidiaries after the date hereof, such information is clearly identified at the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to maintain the confidentiality of such Information as such Person
would accord to its own confidential information. 
 Section 12.16 Termination; Collateral Matters. If the Obligations are
finally and indefeasibly paid and satisfied in full, including, without limitation, all such Obligations arising under Hedge Agreements and/or Cash Management Agreements, all Commitments of the Lenders and the Swing Line have been terminated and are
no longer in effect and this Agreement is terminated, the Administrative Agent and the Lenders shall execute and deliver or cause to be executed and delivered such instruments of satisfaction and reassignment as may be appropriate in order to
release all liens and security interests created by the Security Instruments; provided, however, that in lieu of terminating and repaying any such Obligations arising under any Hedge Agreement with any Lender or Affiliate of any
Lender, the Borrower may provide substitute credit support under a standard form ISDA Credit Support Annex or other credit support documents acceptable to such Lender (or its Affiliate), in its sole discretion, to cover its then current exposure
under such Hedge Agreement and such Lender (and its Affiliate, if applicable) shall have provided written notice to Administrative Agent to the effect that such substitute credit support has been provided to it and that such Lender (and its
Affiliate, if applicable) no longer claim any right, title or interest in any collateral security arising under the Loan Documents to secure any obligations and indebtedness of Borrower or any of its Subsidiaries arising under or related to such
Hedge Agreement, whether then existing or thereafter arising. 
 Section 12.17 Collateral Matters; Hedge Agreements. The benefit
of the Security Instruments and of the provisions of this Agreement relating to any collateral securing the Obligations shall also extend to and be available to (in addition to Lenders and their Affiliates) any Person which is a Secured Swap
Provider or is a party to any Cash Management Agreement with the Borrower or any of its Subsidiaries and shall also extend to Hedge Agreement transactions outstanding on the date of this Agreement with each Person which was a lender or Affiliate of
a lender under the Existing Crimson Credit Agreement on the date of this Agreement. No Approved Counterparty shall have any voting rights under any Loan Document as a result of the existence of Obligations owed to it under any such Hedge Agreements.

 Section 12.18 Exculpation Provisions; No Advisory or Fiduciary Responsibility. (a) EACH OF THE PARTIES HERETO
SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS AGREEMENT AND THE SECURITY INSTRUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT
AND IS FULLY INFORMED AND HAS FULL NOTICE AND KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS
AGREEMENT AND THE SECURITY INSTRUMENTS; AND HAS RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE SECURITY INSTRUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE 

  
 -100- 

 
TERMS OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR
SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND THE SECURITY INSTRUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH
PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 
 (b) In connection with all aspects of each transaction contemplated hereby
(including in connection with any amendment, waiver or other modification hereof or of any other Loan Document), each of the Borrower and the Guarantors acknowledges and agrees, and acknowledges its Affiliates’ understanding, that:
(i) (A) the arranging and other services regarding this Agreement provided by the Administrative Agent, the Arranger and their respective Affiliates are arm’s length commercial transactions between the Borrower, the Guarantors and
their respective Affiliates, on the one hand, and the Administrative Agent, the Arranger and their respective Affiliates, on the other hand and (B) each of the Borrower and the Guarantors is capable of evaluating, and understands and accepts,
the terms, risks and conditions of the transactions contemplated hereby and by the other Loan Documents; (ii) (A) the Administrative Agent, the Arranger, the Lenders and their respective Affiliates each is and has been acting solely as a
principal and, except as expressly agreed in writing by the relevant parties, has not been, is not, and will not be acting as an advisor, agent or fiduciary for the Borrower, the Guarantors or any of their respective Affiliates, or any other Person
and (B) neither the Administrative Agent, the Arranger, the Lenders nor their respective Affiliates has any obligation to the Borrower, the other Guarantors or any of their respective Affiliates with respect to the transactions contemplated
hereby except those obligations expressly set forth herein and in the other Loan Documents; and (iii) the Administrative Agent, the Arranger, the Lenders and their respective Affiliates may be engaged in a broad range of transactions that
involve interests that differ from those of the Borrower, the Guarantors and their respective Affiliates, and neither the Administrative Agent, the Arranger, the Lenders nor their respective Affiliates has any obligation to disclose any of such
interests to the Borrower, the Guarantors or any of their respective Affiliates. To the fullest extent permitted by law, each of the Borrower and the Guarantors hereby waives and releases any claims that it may have against the Administrative Agent,
the Arranger, the Lenders and their respective Affiliates with respect to any breach or alleged breach of agency or fiduciary duty in connection with any aspect of any transaction contemplated hereby. 

Section 12.19 USA PATRIOT Act Notices. Each Lender that is subject to the Act (as hereinafter defined) and the Administrative
Agent (for itself and not on behalf of any Lender) hereby notifies the Borrower that pursuant to the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”),
it is required to obtain, verify and record information that identifies Borrower and each Guarantor, which information includes the name and address of Borrower and each Guarantor and other information that will allow such Lender or the
Administrative Agent, as applicable, to identify Borrower and each Guarantor in accordance with the Act. 

  
 -101- 

 Section 12.20 Keepwell. (a) The Borrower and each Guarantor that is a Qualified
ECP Credit Party hereby jointly and severally guarantees the payment and performance of all Obligations of each Guarantor (other than such Guarantor) and absolutely, unconditionally and irrevocably undertakes to provide such funds or other support
as may be needed from time to time by each Benefitting Guarantor in order for such Benefitting Guarantor to honor its obligations (without giving effect to Section 12.20(b)) under the Guaranty and any other Security Instrument including
obligations with respect to Hedge Agreements (provided, however, that the Borrower or a Guarantor shall only be liable under this Section 12.20(a) for the maximum amount of such liability that can be hereby incurred without
rendering its obligations under this Section 12.20(a), or otherwise under this Agreement or any Loan Document, as it relates to such Benefitting Guarantor, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer,
and not for any greater amount). The obligations of the Borrower and the Guarantors under this Section 12.20(a) shall remain in full force and effect until all Obligations are paid in full to the Lenders, the Administrative Agent and all
Secured Swap Providers, and all of the Lenders’ Commitments are terminated. The Borrower and the Guarantors intend that this Section 12.20(a) constitute, and this Section 12.20(a) shall be deemed to constitute, a “keepwell,
support, or other agreement” for the benefit of each Benefitting Guarantor for all purposes of Section la(18)(A)(v)(II) of the Commodity Exchange Act. 

(b) Notwithstanding any other provisions of this Agreement or any other Loan Document, Obligations guaranteed by any Guarantor, or secured by
the grant of any Lien by any Guarantor under any Security Instrument, shall exclude all Excluded Obligations in respect of a Hedge Agreement with respect to such Guarantor. 

Section 12.21 Flood Insurance Provisions. Notwithstanding any provision in this Agreement or any other Loan Document to the
contrary, in no event is any Building (as defined in the applicable Flood Insurance Regulation) or Manufactured (Mobile) Home (as defined in the applicable Flood Insurance Regulation) included in the definition of “Mortgaged Property” and
no Building or Manufactured (Mobile) Home is hereby encumbered by this Agreement or any other Loan Document. As used herein, “Flood Insurance Regulations” shall mean (a) the National Flood Insurance Act of 1968 as now or hereafter in
effect or any successor statute thereto, (b) the Flood Disaster Protection Act of 1973 as now or hereafter in effect or any successor statue thereto, (c) the National Flood Insurance Reform Act of 1994 (amending 42 USC 4001, et seq.), as
the same may be amended or recodified from time to time and (d) the Flood Insurance Reform Act of 2004 and any regulations promulgated thereunder.

	$[            ]	  	[            ], 201[    ]

 FOR VALUE RECEIVED, CONTANGO OIL & GAS COMPANY, a Delaware corporation (the
“Borrower”) hereby promises to pay [            ] or its registered assigns (the “Lender”), the principal sum of
[            ] ($[            ]) (or such lesser amount as shall equal the aggregate unpaid principal amount of the Loans made by
the Lender to the Borrower under the Credit Agreement, as hereinafter defined), in lawful money of the United States of America and in immediately available funds, on the dates and in the principal amounts provided in the Credit Agreement, and to
pay interest on the unpaid principal amount of each such Loan, at such office, in like money and funds, for the period commencing on the date of such Loan until such Loan shall be paid in full, at the rates per annum and on the dates provided in the
