 Exhibit 10.1 
 NATUS MEDICAL, INC. 
 JOHN BUHLER EMPLOYMENT AGREEMENT 

This Agreement is entered into as of February 14, 2011 (the “Effective Date”), by and between Natus Medical, Inc. (the
“Company”), and John Buhler (“Executive”). 
 1. Duties and Scope of Employment. 

(a) Positions and Duties. As of the Effective Date, Executive will serve as President and Chief Operating Officer of the
Company. Executive will render such business and professional services in the performance of his duties, consistent with Executive’s position within the Company, as shall reasonably be assigned to him by the Company’s Chief Executive
Officer (“CEO”). The period of Executive’s employment under this Agreement is referred to herein as the “Employment Term.” 
 (b) Obligations. During the Employment Term, Executive will perform his duties faithfully and to the best of his ability and will devote his full business efforts and time to the Company.
For the duration of the Employment Term, Executive agrees not to actively engage in any other employment, occupation or consulting activity for any direct or indirect remuneration without the prior approval of the Board. 

2. At-Will Employment. The parties agree that Executive’s employment with the Company will be “at-will” employment and
may be terminated at any time with or without cause or notice. Executive understands and agrees that neither his job performance nor promotions, commendations, bonuses or the like from the Company give rise to or in any way serve as the basis for
modification, amendment, or extension, by implication or otherwise, of his employment with the Company. 
 3. Compensation.

 (a) Base Salary. During the Employment Term, the Company will pay Executive an annual salary of $325,000 as
compensation for his services (the “Base Salary”). The Base Salary will be paid periodically in accordance with the Company’s normal payroll practices and be subject to the usual, required withholding. Executive’s salary will be
subject to review and adjustments will be made based upon the Company’s normal performance review practices. 
 (b)
Performance Bonus. Executive shall be eligible to receive a cash bonus pursuant to the Company’s 2011 cash incentive plan, with a target bonus amount of 50% of Executive’s Base Salary actually paid during the year, less applicable
withholding taxes, at target achievement of the performance objectives previously established under the plan by the Company’s Compensation Committee. The 2011 cash incentive plan is based on the Company achieving its budgeted income before
provision for income tax for 2011 (“pre-tax profit”); bonuses may range from 50% to a maximum of 150% of the target bonus amount, pro-rated based on the amount of actual pre-tax profit relative to the budgeted amount. Actual pre-tax profit
must be at 80% of target for minimum payments and maximum payments will be made upon achieving 120% of target. Payment of bonuses pursuant to this plan is authorized in the discretion of the Board of Directors.The amount of, and performance
objectives for, performance bonus in years after 2011 will be subject to the determination of the Compensation Committee. Any performance bonus payments shall be made in accordance with the terms of the applicable cash incentive plan and in no case
later than March 15 of the year following the year in which the right to a performance bonus is earned. 
 (c) Equity Awards. Executive shall receive options to purchase 120,000 shares of Company Common Stock on Executive’s first day of employment, pursuant to and governed by the terms of the
Company’s Amended and Restated 2000 Stock Awards Plan (“2000 Plan”), with an exercise price at the date of grant determined in accordance with the 2000 Plan. Vesting begins six (6) months from and is retroactive to your start
date. Stock vests at 1/48th per month.
Notwithstanding any other provision of the Agreement, under no circumstances shall Executive have any right to exercise stock options before Executive has completed one-hundred-eighty-days of employment. Executive shall also receive 60,000 shares of
restricted stock pursuant to and governed by the terms of the 2000 Plan, which shares shall vest at the rate of 50% on the second anniversary of the grant, 25% on the third anniversary of the grant, and the final 25% on the fourth anniversary of the
grant. Executive shall be eligible for future equity awards commencing in 2012, along with other executive officers of the Company, as determined by the Company’s Compensation Committee. 

 (d) Reimbursement of Relocation Expenses. Company agrees to reimburse
Executive’s actual relocation expenses up to a maximum of $50,000, and Executive agrees to repay Company for any such reimbursement in the event he voluntarily terminates his employment within one year after his first day of employment with the
Company. 
 4. Employee Benefits. During the Employment Term, Executive will be entitled to participate in the employee benefit
plans currently and hereafter maintained by the Company of general applicability to other senior executives of the Company, including, without limitation, the Company’s group medical, dental, vision, disability, life insurance, and
flexible-spending account plans consistent with the terms of such plans. The Company reserves the right to cancel or change the benefit plans and programs it offers to its employees at any time. 

5. Paid Time Off (“PTO”). Executive is entitled to receive PTO pursuant to Natus’ standard benefit policy currently and
hereafter maintained by the Company, and as may be cancelled or changed from time to time. 
 6. Expenses. The Company will
reimburse Executive for reasonable travel, entertainment or other expenses incurred by Executive in the furtherance of or in connection with the performance of Executive’s duties hereunder, in accordance with the Company’s expense
reimbursement policy as in effect from time to time. 
 7. Severance. 

(a) Involuntary Termination. If Executive’s employment with the Company terminates other than for “Cause”
(as defined herein), death or disability, and Executive signs and does not revoke a standard release of claims with the Company, then, subject to Section 11, Executive shall be entitled to (i) receive continuing payments of severance pay
(less applicable withholding taxes) at a rate equal to his Base Salary rate, as then in effect, for a period equal to six months, plus one month for each two months of employment, up to a maximum of 12 months from the date of Executive’s
“separation from service” (as defined in Treas. Reg. 1.409A-1(h)) with the Company, to be paid periodically in accordance with the Company’s normal payroll policies and commencing with the latest payroll date that is also within
seventy (70) days from the date of “separation from service” provided that the required release is effective on such date (with payments that would have been made on earlier payroll dates, but for this provision, cumulated and paid on
such payroll date); (ii) the immediate vesting and exercisability of 100 % of the shares subject to all of Executive’s stock options to purchase Company Common Stock (whether currently outstanding or granted following the Effective
Date) outstanding on the date of such termination (the “Stock Options”) and no additional vesting of any shares of restricted stock or restricted stock units outstanding on the date of such termination beyond the amount of such awards that
is vested as of such date of termination (with settlement of any restricted stock units to be in accordance with the terms of such awards), and (iii) continued payment by the Company of the group health continuation coverage premiums for
Executive and Executive’s eligible dependents under Title X of the Consolidated Budget Reconciliation Act of 1985, as amended (“COBRA”) as in effect through the lesser of (x) six months from the effective date of such
termination, (y) the date upon which Executive and Executive’s eligible dependents become covered under similar plans, or (z) the date Executive no longer constitutes a “Qualified Beneficiary” (as such term is defined in
Section 4980B(g) of the Internal Revenue Code of 1986, as amended (the “Code”)); provided, however, that Executive will be solely responsible for electing such coverage within the required time periods. 

(b) Voluntary Termination; Termination for Cause. If Executive’s employment with the Company terminates voluntarily
by Executive (other than as described in subsection (c) below) or for Cause by the Company or due to Executive’s death or disability, then (i) all vesting of Stock Options and restricted stock and restricted stock units will
immediately cease, (ii) all payments of compensation by the Company to Executive hereunder will terminate immediately (except as to amounts already earned), and (iii) Executive will only be eligible for severance benefits, if any, in
accordance with the Company’s established policies as then in effect. 
 (c) Change of Control
Benefits. If within twelve (12) months following a “Change of Control” (as defined below) (i) Executive terminates Executive’s employment with the Company for Good Reason after providing the Company with written
notice within the ninety (90) days after the occurrence of an event constituting Good Reason and an opportunity for the Company to cure such occurrence of not less than thirty (30) days, or (ii) the Company or the successor
corporation terminates Executive’s employment with the Company for other than Cause, death or disability, then Executive shall be entitled to the benefits provided for in subsection (a). Executive shall only be permitted to receive the benefits
provided for in subsection (a) once and shall not be permitted to claim such benefits under both subsection (a) and (c) such that Executive would receive the benefits pursuant to subsection (a) twice. The payment-characterization
provisions made under subsection (a) above for purposes of Section 409A of the Code shall apply as well. 

 8. Limitation on Payments. In the event that the severance and other benefits provided for
in this Agreement or otherwise payable to the Executive (i) constitute “parachute payments” within the meaning of Section 280G of the Code and (ii) but for this Section 8, would be subject to the excise tax imposed by
Section 4999 of the Code, then the Executive’s severance benefits under Section 4(a)(i) shall be either: 
  

	 	•	 	 delivered in full, or 

  

	 	•	 	 delivered as to such lesser extent which would result in no portion of such severance benefits being subject to excise tax under Section 4999 of
the Code, 

  

	 	•	 	 whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by
Section 4999, results in the receipt by Executive on an after-tax basis, of the greatest amount of severance benefits, notwithstanding that all or some portion of such severance benefits may be taxable under Section 4999 of the Code.
Unless the Company and Executive otherwise agree in writing, any determination required under this Section 8 shall be made in writing by the Company’s independent public accountants immediately prior to Change of Control (the
“Accountants”), whose determination shall be conclusive and binding upon Executive and the Company for all purposes. For purposes of making the calculations required by this Section 8, the Accountants may make reasonable assumptions
and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code. The Company and Executive shall furnish to the Accountants such information and
documents as the Accountants may reasonably request in order to make a determination under this Section. The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section 8.
If payment is to be in a lesser amount then reduction shall occur in the following order: (i) reduction of payments of cash; and (ii) reduction in equity awards; and in each category reduction shall be pro rata between those payments
subject to Section 409A and payments not subject to Section 409A. 

 9. Definitions. 

(a) Cause. For purposes of this Agreement, “Cause” shall mean (i) any act of personal dishonesty taken by
Executive in connection with his responsibilities as an employee and intended to result in substantial personal enrichment of Executive, (ii) Executive’s conviction of a felony, (iii) a willful act by Executive which constitutes gross
misconduct and which is injurious to the Company, or (iv) continued substantial violations by Executive of Executive’s employment duties which are demonstrably willful and deliberate on Executive’s part after there has been delivered
to Executive a written demand for performance from the Company which specifically sets forth the factual basis for the Company’s belief that Executive has not substantially performed Executive’s duties. 

(b) Change of Control. For purposes of this Agreement, “Change of Control” of the Company is defined as:

 (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as
amended) is or becomes the “beneficial owner” (as defined in Rule 13d-3 under said Act), directly or indirectly, of securities of the Company representing 50% or more of the total voting power represented by the Company’s then
outstanding voting securities; or 
 (ii) a change in the composition of the Board occurring within a two-year period, as a
result of which fewer than a majority of the directors are Incumbent Directors. “Incumbent Directors” will mean directors who either (A) are directors of the Company as of the date hereof, or (B) are elected, or nominated for
election, to the Board with the affirmative votes of at least a majority of the Incumbent Directors at the time of such election or nomination (but will not include an individual whose election or nomination is in connection with an actual or
threatened proxy contest relating to the election of directors to the Company); or 

 (iii) the date of the consummation of a merger or consolidation of the Company with any
other corporation that has been approved by the stockholders of the Company, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by
remaining outstanding or by being converted into voting securities of the surviving entity) more than forty percent (40%) of the total voting power represented by the voting securities of the Company or such surviving entity outstanding
immediately after such merger or consolidation, or the stockholders of the Company approve a plan of complete liquidation of the Company; or 
 (iv) the date of the consummation of the sale or disposition by the Company of all or substantially all the Company’s assets; or 

(v) the termination of the CEO (in place on the Effective Date) for other than Cause, death or disability. 

(c) Good Reason. For purposes of this Agreement, “Good Reason” shall mean any of the following actions taken
without the Executive’s express written consent: (i) the material reduction of the Executive’s duties or responsibilities relative to Executive’s duties or responsibilities in effect immediately prior to such reduction; provided,
however, that a reduction in duties or responsibilities solely by virtue of the Company being acquired and made part of a larger entity (as, for example, when the Chief Financial Officer of Natus Medical Incorporated remains as such following a
Change of Control and is not made the Chief Financial Officer of the acquiring corporation) shall not constitute “Good Reason;” (ii) a material reduction by the Company in Executive’s annual Base Salary as in effect immediately
prior to such reduction; (iii) a material reduction by the Company in the kind or level of employee benefits to which Executive is entitled immediately prior to such reduction with the result that Executive’s overall benefits package is
significantly reduced; (iv) the relocation of Executive’s primary place of work to a facility or a location that increases Executive’s commute distance by more than 35 miles from Executive’s then primary place of work ; or
(v) the material breach of this Agreement by the Company (including, but not limited to, failure of the Company to obtain the assumption of this Agreement by any successors contemplated in Section 12). 

10. Confidential Information. Executive agrees to enter into the Company’s standard Confidential Information and Invention
Assignment Agreement (the “Confidential Information Agreement”) upon commencing employment hereunder. 
 11. Conditional
Nature of Severance Payments. 
 (a) Noncompete. Executive acknowledges that the nature of the
Company’s business is such that if Executive were to become employed by, or substantially involved in, the business of a competitor of the Company following the termination of Executive’s employment with the Company, it would be very
difficult for Executive not to rely on or use the Company’s trade secrets and confidential information. Thus, to avoid the inevitable disclosure of the Company’s trade secrets and confidential information, Executive agrees and acknowledges
that Executive’s right to receive the severance payments set forth in Section 7 (to the extent Executive is otherwise entitled to such payments) shall be conditioned upon Executive not directly or indirectly engaging in (whether as an
employee, consultant, agent, proprietor, principal, partner, stockholder, corporate officer, director or otherwise), nor having any ownership interest in or participating in the financing, operation, management or control of, any person, firm,
corporation or business that competes with Company or is a customer of the Company. Upon any breach of this section, all severance payments pursuant to this Agreement shall immediately cease. 

(b) Non-Solicitation. Until the date eighteen (18) months after the termination of Executive’s employment with
the Company for any reason, Executive agrees not, either directly or indirectly, to solicit, induce, attempt to hire, recruit, encourage, take away, hire any employee of the Company or cause an employee to leave his or her employment either for
Executive or for any other entity or person. Additionally, Executive acknowledges that Executive’s right to receive the severance payments set forth in Section 7 (to the extent Executive is otherwise entitled to such payments) are
contingent upon Executive complying with this Section 10(b) and upon any breach of this section all severance payments pursuant to this Agreement shall immediately cease. 
 (c) Understanding of Covenants. Executive represents that Executive (i) is familiar with the foregoing covenants not to compete and not to solicit, and (ii) is fully aware of
Executive’s obligations hereunder, including, without limitation, the reasonableness of the length of time, scope and geographic coverage of these covenants. 

 12. Code Section 409A. For purposes of this Agreement, a termination of employment will be
determined consistent with the rules relating to a “separation from service” as defined in Section 409A of the Code and the regulations thereunder (“Section 409A”). Notwithstanding anything else provided herein, to the
extent any payments provided under this Agreement in connection with Executive’s termination of employment constitute deferred compensation subject to Section 409A, and Executive is deemed at the time of such termination of employment to
be a “specified employee” under Section 409A, then such payment shall not be made or commence until the earlier of (i) the expiration of the 6-month period measured from Executive’s separation from service from the Company
or (ii) the date of Executive’s death following such a separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax treatment to Executive including, without limitation,
the additional tax for which Executive would otherwise be liable under Section 409A(a)(1)(B) in the absence of such a deferral. The first payment thereof will include a catch-up payment covering the amount that would have otherwise been paid
during the period between Executive’s termination of employment and the first payment date but for the application of this provision, and the balance of the installments (if any) will be payable in accordance with their original schedule. To
the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A, the provision will be read in such a manner so that all payments hereunder comply with Section 409A. To the extent any payment under this
Agreement may be classified as a “short-term deferral” within the meaning of Section 409A, such payment shall be deemed a short-term deferral, even if it may also qualify for an exemption from Section 409A under another provision
of Section 409A. Payments pursuant to this section are intended to constitute separate payments for purposes of Section 1.409A-2(b)(2) of the Treasury Regulations. Except as otherwise expressly provided herein, to the extent any expense
reimbursement or the provision of any in-kind benefit under this Agreement is determined to be subject to Section 409A of the Code, the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one
calendar year shall not affect the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day
of the calendar year following the calendar year in which the Executive incurred such expenses, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit.

 13. Assignment. This Agreement will be binding upon and inure to the benefit of (a) the heirs, executors and legal
representatives of Executive upon Executive’s death and (b) any successor of the Company. Any such successor of the Company will be deemed substituted for the Company under the terms of this Agreement for all purposes. For this purpose,
“successor” means any person, firm, corporation or other business entity which at any time, whether by purchase, merger or otherwise, directly or indirectly acquires all or substantially all of the assets or business of the Company. None
of the rights of Executive to receive any form of compensation payable pursuant to this Agreement may be assigned or transferred except by will or the laws of descent and distribution. Any other attempted assignment, transfer, conveyance or other
disposition of Executive’s right to compensation or other benefits will be null and void. 
 14. Notices. All notices,
requests, demands and other communications called for hereunder shall be in writing and shall be deemed given (i) on the date of delivery if delivered personally, (ii) one (1) day after being sent by a well established commercial
overnight service, or (iii) four (4) days after being mailed by registered or certified mail, return receipt requested, prepaid and addressed to the parties or their successors at the following addresses, or at such other addresses as the
parties may later designate in writing: 
 If to the Company: 

Natus Medical, Inc. 
 1501 Industrial Road 
 San Carlos, CA 94070 

Attn: James B. Hawkins, Chief Executive Officer 
 If to Executive: 
 at the last residential address known by the Company.

 15. Severability. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement will continue in full force and effect without said provision. 

 16. Arbitration. 
 (a) General. In consideration of Executive’s service to the Company, its promise to arbitrate all employment related disputes and Executive’s receipt of the compensation, pay
raises and other benefits paid to Executive by the Company, at present and in the future, Executive agrees that any and all controversies, claims, or disputes with anyone (including the Company and any employee, officer, director, shareholder or
benefit plan of the Company in their capacity as such or otherwise) arising out of, relating to, or resulting from Executive’s service to the Company under this Agreement or otherwise or the termination of Executive’s service with the
Company, including any breach of this Agreement, shall be subject to binding arbitration under the Arbitration Rules set forth in California Code of Civil Procedure Section 1280 through 1294.2, including Section 1283.05 (the
“Rules”) and pursuant to California law. Disputes which Executive agrees to arbitrate, and thereby agrees to waive any right to a trial by jury, include any statutory claims under state or federal law, including, but not limited to, claims
under Title VII of the Civil Rights Act of 1964, the Americans with Disabilities Act of 1990, the Age Discrimination in Employment Act of 1967, the Older Workers Benefit Protection Act, the California Fair Employment and Housing Act, the California
Labor Code, claims of harassment, discrimination or wrongful termination and any statutory claims. Executive further understands that this Agreement to arbitrate also applies to any disputes that the Company may have with Executive. 

(b) Procedure. Executive agrees that any arbitration will be administered by the American Arbitration Association
(“AAA”) and that a neutral arbitrator will be selected in a manner consistent with its National Rules for the Resolution of Employment Disputes. The arbitration proceedings will allow for discovery according to the rules set forth in the
National Rules for the Resolution of Employment Disputes or California Code of Civil Procedure. Executive agrees that the arbitrator shall have the power to decide any motions brought by any party to the arbitration, including motions for
summary judgment and/or adjudication and motions to dismiss and demurrers, prior to any arbitration hearing. Executive agrees that the arbitrator shall issue a written decision on the merits. Executive also agrees that the arbitrator shall have the
power to award any remedies, including attorneys’ fees and costs, available under applicable law. Executive understands the Company will pay for any administrative or hearing fees charged by the arbitrator or AAA except that Executive shall pay
the first $200.00 of any filing fees associated with any arbitration Executive initiates. Executive agrees that the arbitrator shall administer and conduct any arbitration in a manner consistent with the Rules and that to the extent that the
AAA’s National Rules for the Resolution of Employment Disputes conflict with the Rules, the Rules shall take precedence. 

(c) Remedy. Except as provided by the Rules, arbitration shall be the sole, exclusive and final remedy for any dispute
between Executive and the Company. Accordingly, except as provided for by the Rules, neither Executive nor the Company will be permitted to pursue court action regarding claims that are subject to arbitration. Notwithstanding, the arbitrator will
not have the authority to disregard or refuse to enforce any lawful Company policy, and the arbitrator shall not order or require the Company to adopt a policy not otherwise required by law that the Company has not adopted. 

(d) Availability of Injunctive Relief. In addition to the right under the Rules to petition the court for provisional
relief, Executive agrees that any party may also petition the court for injunctive relief where either party alleges or claims a violation of this Agreement or the Confidentiality Agreement or any other agreement regarding trade secrets,
confidential information, nonsolicitation or Labor Code §2870. In the event either party seeks injunctive relief, the prevailing party shall be entitled to recover reasonable costs and attorneys’ fees. 

(e) Administrative Relief. Executive understands that this Agreement does not prohibit Executive from pursuing an
administrative claim with a local, state or federal administrative body such as the Department of Fair Employment and Housing, the Equal Employment Opportunity Commission or the workers’ compensation board. This Agreement does, however,
preclude Executive from pursuing court action regarding any such claim. 
 (f) Voluntary Nature of
Agreement. Executive acknowledges and agrees that Executive is executing this Agreement voluntarily and without any duress or undue influence by the Company or anyone else. Executive further acknowledges and agrees that Executive has
carefully read this Agreement and that Executive has asked any questions needed for Executive to understand the terms, consequences and binding effect of this Agreement and fully understand it, including that Executive is waiving Executive’s
right to a jury trial. Finally, Executive agrees that Executive has been provided an opportunity to seek the advice of an attorney of Executive’s choice before signing this Agreement. 

 17. Integration. This Agreement, together with the any Company stock awards plan pursuant
to which stock options, restricted stock, restricted stock units or other equity awards have been made to Executive, any agreements representing any such equity awards, and the Confidential Information Agreement represents the entire agreement and
understanding between the parties as to the subject matter herein and supersedes all prior or contemporaneous agreements whether written or oral. No waiver, alteration, or modification of any of the provisions of this Agreement will be binding
unless it is in writing and specifically mentions this Section 16 and it is signed by duly authorized representatives of the parties hereto. 
 18. Waiver of Breach. The waiver of a breach of any term or provision of this Agreement, which must be in writing, shall not operate as or be construed to be a waiver of any other
previous or subsequent breach of this Agreement. 
 19. Headings. All captions and section headings used in this Agreement are
for convenient reference only and do not form a part of this Agreement. 
 20. Tax Withholding. All payments made pursuant to
this Agreement will be subject to withholding of applicable taxes. 
 21. Governing Law. This Agreement will be governed by the
laws of the State of California (with the exception of its conflict of laws provisions). 
 22. Acknowledgment. Executive
acknowledges that he has had the opportunity to discuss this matter with and obtain advice from his private attorney, has had sufficient time to, and has carefully read and fully understands all the provisions of this Agreement, and is knowingly and
voluntarily entering into this Agreement. 
 23. Counterparts. This Agreement may be executed in counterparts, and each
counterpart shall have the same force and effect as an original and shall constitute an effective, binding agreement on the part of each of the undersigned. 
 IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the case of the Company by their duly authorized officers, as of the day and year first above written.

in this Section 1.1 or in the sections and subsections referred to below: 
 “ABR Loan”
means a Loan that bears interest at a fluctuating rate determined by reference to the Alternate Base Rate. 

“ABR Payment Date” means (a) the last Business Day of March, June, September and December of each

principal on the Notes shall be deferred from one ABR Payment Date to another day, such other day shall also be an ABR Payment Date. 
 “Affiliate” means, as to any Person, each other Person that directly or indirectly (through one or more intermediaries or otherwise) controls, is controlled by, or is under common control
with, such Person. A Person shall be deemed to be “controlled by” any other Person if such other Person possesses, directly or indirectly, the power to direct or cause the direction of the management or policies of a Person, whether
through the ability to exercise voting power, by contract or otherwise.

Commitments made in accordance with this Agreement.

of the effective time of each such change. The Alternate Base Rate shall in no event, however, exceed the Highest Lawful Rate. If for any reason the Agent shall have determined (which determination shall be conclusive and binding, absent manifest
error) that it is unable to ascertain the Federal Funds Rate for any reason, including, without limitation, the inability or failure of the Agent to obtain sufficient bids or publications in accordance with the terms hereof, the Alternate Base Rate
shall be determined using the Prime Rate until the circumstances giving rise to such inability no longer exist.

Office in the case of ABR Loans and such Lender’s Eurodollar Lending Office in the case of Eurodollar Loans. 
 “Applicable Margin” means, for any day and with respect to all Loans maintained as Eurodollar Loans or ABR Loans, the applicable percentage set forth below corresponding to the Borrowing

(a) specify (i) the aggregate amount of any such Borrowing of new ABR Loans and the Business Day on
which such ABR Loans are to be advanced, (ii) the aggregate amount of any such Borrowing of new Eurodollar Loans, the Business Day on which such Eurodollar Loans are to be advanced (which shall be the first day of the Interest Period which is
to apply thereto), and the length of the applicable Interest Period, and (iii) with respect to the Borrowing Notice delivered on or before the Closing Date, which Loans are to be advanced as Revolving Loans; and

City time, on (i) the Business Day on which any such ABR Loans are to be made, or (ii) the third Business Day preceding the Business Day on which any such Eurodollar Loans are to be made. 

Each such written request or confirmation must be made in the form and substance of the “Borrowing Notice” attached hereto as
Exhibit B, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon receipt of any such
Borrowing Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Borrowing Notice shall be irrevocable and binding on Borrower. If all conditions precedent to such new Loans have been met, each Lender will on the date
requested promptly remit to Agent at Agent’s office in New York, New York, the amount of such Lender’s new Loan in immediately available funds, and upon receipt of such funds, unless to its actual knowledge any conditions precedent to such
Loans have been neither met nor waived as provided herein, Agent shall promptly make such Loans available to Borrower. Unless Agent shall have received prompt notice from a Lender that such Lender will not make available to Agent such Lender’s
new Loan, Agent may in its discretion assume that such Lender has made such Loan available to Agent in accordance with this section and Agent may if it chooses, in reliance upon such assumption, make such Loan available to Borrower. If and to the
extent such Lender shall not so make its new Loan available to Agent, such Lender and Borrower severally agree to pay or repay to Agent within three days after demand the amount of such Loan together with interest thereon, for each day from the date

Lender and from Borrower, on demand, interest thereon at the Default Rate, calculated from the date such amount was made available to Borrower. The failure of any Lender to make any new Loan to be made by it hereunder shall not relieve any other
Lender of its obligation hereunder, if any, to make its new Loan, but no Lender shall be responsible for the failure of any other Lender to make any new Loan to be made by such other Lender. 

Section 2.3. Continuations and Conversions of Existing Loans. Borrower may make the following elections with
respect to Loans already outstanding: to convert ABR Loans to Eurodollar Loans, to convert Eurodollar Loans to ABR Loans on the last day of the Interest Period applicable thereto, or to continue Eurodollar Loans beyond the expiration of such
Interest Period by designating a new Interest Period to take effect at the time of such expiration. In making such elections, Borrower may combine existing Loans made pursuant to separate Borrowings into one new Borrowing or divide existing Loans
made pursuant to one Borrowing into separate new Borrowings. To make any such election, Borrower must give to Agent written notice (or telephonic notice promptly confirmed in writing) of any such conversion or continuation of existing Loans, with a
separate notice given for each new Borrowing. Each such notice constitutes a “Continuation/Conversion Notice” hereunder and must: 
 (a) specify the existing Loans which are to be continued or converted; 

  
 28 

 (b) specify (i) the aggregate amount of any Borrowing
of ABR Loans into which such existing Loans are to be continued or converted and the date on which such continuation or conversion is to occur, or (ii) the aggregate amount of any Borrowing of Eurodollar Loans into which such existing Loans are
to be continued or converted, the date on which such continuation or conversion is to occur (which shall be the first day of the Interest Period which is to apply to such Eurodollar Loans), and the length of the applicable Interest Period; and

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

Each such written request or confirmation must be made in the form and substance of the “Continuation/Conversion Notice”
attached hereto as Exhibit C, duly completed. Each such telephonic request shall be deemed a representation, warranty, acknowledgment and agreement by Borrower as to the matters which are required to be set out in such written confirmation. Upon
receipt of any such Continuation/Conversion Notice, Agent shall give each Lender prompt notice of the terms thereof. Each Continuation/Conversion Notice shall be irrevocable and binding on Borrower. During the continuance of any Default, Borrower
may not make any election to convert existing Loans into Eurodollar Loans or continue existing Loans as Eurodollar Loans. If (due to the existence of a Default or for any other reason) Borrower fails to timely and properly give any notice of
continuation or conversion with respect to a Borrowing of existing Eurodollar Loans at least three days prior to the end of the Interest Period applicable thereto, such Eurodollar Loans shall automatically be converted into ABR Loans at the end of
such Interest Period. No new funds shall be repaid by Borrower or advanced by any Lender in connection with any continuation or conversion of existing Loans pursuant to this section, and no such continuation or conversion shall be deemed to be a new
advance of funds for any purpose; such continuations and conversions merely constitute a change in the interest rate applicable to already outstanding Loans. 
 Section 2.4. Use of Proceeds. Borrower shall use all Loans to finance capital expenditures, and provide working capital for its operations and for other general business purposes, including
the acquisition of oil and gas properties and related assets. In no event shall the funds from any Loan be used directly or indirectly by any Person (a) for personal, family, household or agricultural purposes or (b) for the purpose,
whether immediate, incidental or ultimate, of purchasing, acquiring or carrying any “margin stock” or any “margin securities” (as such terms are defined respectively in Regulation T, U and X promulgated by the Board of Governors)
or to extend credit to others directly or indirectly for the purpose of purchasing or carrying any such margin stock or margin securities or (c) for the acquisition of any Person unless such acquisition has been approved by the board of
directors, management committee or partners, as the case may be of such Person. Borrower represents and warrants that Borrower is not engaged principally, or as one of Borrower’s important activities, in the business of extending credit to
others for the purpose of purchasing or carrying such margin stock or margin securities. 
 Section 2.5.
Fees. 

  
 29 

 (a) Commitment Fees. In consideration of each
Revolving Loan Lender’s commitment to make Revolving Loans, Borrower will pay to Agent for the account of each Revolving Loan Lender (excluding any Defaulting Lenders) a commitment fee determined on a daily basis by applying the Commitment Fee
Rate to such Revolving Loan Lender’s Revolving Loan Percentage Share of the unused portion of the Borrowing Base that is available for Revolving Loans on each day during the Commitment Period. This commitment fee will be due and payable in
arrears on each ABR Payment Date and at the end of the Commitment Period. 
 (b) Other
Fees. In addition to all other amounts due to Agent under the Loan Documents, Borrower will pay fees to Agent and TD Securities (USA) LLC as described in a letter agreement dated as of April 6, 2011 between Agent, TD Securities (USA) LLC
and Borrower. 
 (c) Letter of Credit Stated Amount Fee. The Borrower agrees to pay to the
Agent, for the account of each Lender (excluding any Defaulting Lenders), a participation fee with respect to its participations in Letters of Credit, for the period from and including the date of the issuance of such Letter of Credit to (but not
including) the date upon which such Letter of Credit expires, at a rate per annum equal to Eurodollar Margin on the Stated Amount (as such Stated Amount may be adjusted, from time to time, as a result of drawings thereunder) of such Letter of
Credit, based on a year comprised of three-hundred and sixty (360) days (such participation fee, “Letter of Credit Fee”). A prorated portion of such fee shall be payable by the Borrower in arrears on each ABR Payment Date, and
at the end of the Commitment Period for any period then ending for which such fee shall not theretofore have been paid, commencing on the first such date after the issuance of such Letter of Credit. 

(d) Letter of Credit Issuance Fee. The Borrower agrees to pay to each Issuer for its own account an
issuance fee for each Letter of Credit issued by such Issuer equal to the greater of (i) $500 or (ii) 0.25% of the Stated Amount of such Letter of Credit. Such fee shall be payable by the Borrower quarterly in arrears. The Borrower also
agrees to pay such Issuer’s standard fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder, which fees shall be payable to such Issuer within ten (10) days after
demand. 
 (e) Initial Upfront Fee. The Borrower will pay to the Administrative Agent, for
the account of the Lenders (including TD (Texas), (a) an upfront fee on each Lender’s Commitment level as limited by the Borrowing Base then in effect on the Closing Date and, (b) upon closing of the Fairway Acquisition, an
incremental upfront fee will be paid in respect of each Lender’s increase in Commitment level resulting from the increase in Borrowing Base above the Initial Availability Amount resulting from such closing. The upfront fee tier will be based on
each Lender’s Commitment to the Borrowing Base as shown in the chart below: 

  
 30 

									
	 Commitment Level
	 	 	  	 	Upfront Fee	 
	$	75,000,000	  	 		 	 	100 bps	  
	$	50,000,000	  	 		 	 	75 bps	  
	$	35,000,000	  	 		 	 	50 bps	  

 (f) Additional Upfront Fees. In the event that, as a result of a redetermination of the Borrowing Base, the Borrowing Base is increased to an amount that is higher than $575,000,000 (the
“Base Amount”; and such higher amount herein the “Designated Amount”), the Borrower agrees to pay to the Agent, for the account of each Revolving Loan Lender (excluding any Defaulting Lenders), an upfront fee in an
amount to be agreed upon between the Borrower and the Agent, according to such Revolving Loan Lender’s Revolving Loan Percentage Share of the difference between the Designated Amount and the Base Amount; provided, however, that solely for
purposes of calculating the upfront fee pursuant to this clause (e), upon payment of such upfront fee and for purposes of future upfront fees pursuant to this clause (e), the Base Amount shall be increased to be equal to the last Designated Amount
for which an upfront fee has been paid hereunder. 
 Section 2.6. Optional Prepayments. Borrower
may, upon one Business Day’s notice in the case of ABR Loans, or three Business Days’ notice in the case of Eurodollar Loans, to Agent for the account of each Lender, from time to time and without premium or penalty prepay the Revolving
Loans, in whole or in part, so long as the aggregate amounts of all partial prepayments of principal on such prepaid Loans equals $1,000,000 or any higher integral multiple of $1,000,000, so long as Borrower pays all breakage costs associated with
the prepayment of any Eurodollar Loan as provided in Section 3.5, and so long as Borrower does not make any prepayments which would reduce the unpaid principal balance of any Loan to less than $1,000,000 without first either
(a) terminating this Agreement or (b) providing assurance satisfactory to Agent in its discretion that Lenders’ legal rights under the Loan Documents are in no way affected by such reduction. Each prepayment of principal of a
Eurodollar Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this section shall be in addition to, and not in lieu of, all payments
otherwise required to be paid under the Loan Documents at the time of such prepayment. 
 Section 2.7.
Mandatory Prepayments. 
 (a) If at any time the Facility Usage exceeds the Aggregate
Commitments (whether due to a reduction or termination in any Commitments in accordance with this Agreement, or otherwise), Borrower shall immediately upon demand prepay the principal of the Loans (and/or provide cash collateral for Letters of
Credit) in an amount at least equal to such excess in accordance with clause (g) below. 

(b) If at any time the Facility Usage is less than the Aggregate Commitments but in excess of the
Borrowing Base (such excess being herein called a “Borrowing Base Deficiency”), Borrower shall, within five Business Days after Agent gives notice of such fact to Borrower, either: 

  
 31 

 (i) prepay the principal of the Loans (and/or provide cash
collateral for Letters of Credit) in accordance with clause (g) below in an aggregate amount at least equal to such Borrowing Base Deficiency; or 

(ii) give notice to Agent electing to prepay the principal of the Loans (and/or provide cash collateral)
in accordance with clause (g) below in up to three monthly installments in an aggregate amount at least equal to such Borrowing Base Deficiency, with each such installment equal to or in excess of one-third of such Borrowing Base Deficiency,
and with the first such installment to be paid one month after the giving of such notice and the subsequent installments to be due and payable at one month intervals thereafter until such Borrowing Base Deficiency has been eliminated; or 

(iii) give notice to Agent that Borrower desires to provide Agent with deeds of trust, mortgages, chattel
mortgages, security agreements, financing statements and other security documents in form and substance satisfactory to Agent, granting, confirming, and perfecting first and prior liens or security interests in collateral acceptable to Required
Lenders, to the extent needed to allow Required Lenders to increase the Borrowing Base (as they in their reasonable discretion deem consistent with prudent oil and gas banking industry lending standards at the time) to an amount which eliminates
such Borrowing Base Deficiency, and then provide such security documents within thirty days after Agent specifies such collateral to Borrower. If, prior to any such specification by Agent, Required Lenders determine that the giving of such security
documents will not serve to eliminate such Borrowing Base Deficiency, then, within five Business Days after receiving notice of such determination, Borrower will elect to make, and thereafter make, the prepayments specified in either of the
preceding subsections (i) or (ii) of this subsection (b); 
 provided, however, that if a
Borrowing Base Deficiency is existing as a result of any Subject Sale or other sale, and the corresponding reduction of the Borrowing Base (including the Initial Availability Amount), pursuant to Section 7.5, the Borrower shall instead
immediately prepay the Loans (and/or provide cash collateral for Letters of Credit) in accordance with Section 7.5 from the proceeds of such Subject Sale or sale, as appropriate, to the extent of the Borrowing Base Deficiency that resulted from
such sale and reduction. 
 (c) [Reserved]. 

(d) [Reserved]. 

(e) Upon the occurrence of a Borrowing Base Deficiency resulting from a Casualty Event pursuant to
Section 2.9 (subject to the Borrower’s and the applicable Subsidiaries’ rights contained in the second paragraph of Section 2.9), the Borrower will forthwith utilize the Net Cash Proceeds of such Casualty Event to prepay the
principal of the Loans (and/or provide cash collateral for Letters of Credit) in an amount sufficient to cure such Deficiency in accordance with clause (g) below. 

  
 32 

 (f) The Borrower will prepay the Loans (and/or provide cash
collateral) to the extent otherwise required by the other provisions of this Agreement. 
 (g) In
the event that the Borrower is required to prepay the Loans (and/or provide cash collateral) pursuant to clause (a), (b) or (e) above, the Borrower shall prepay the Loans (and/or provide cash collateral) in the following order of priority:
(i) first, to the prepayment of Revolving Loans that are ABR Loans and then to the prepayment of Revolving Loans that are Eurodollar Loans, and (ii) second, to provide cash collateral to the applicable Issuer in the applicable amount in
respect of any outstanding Letters of Credit in accordance with the general provisions of Section 2.1 l(g); 
 (h) Each prepayment of principal of a Loan under this section shall be accompanied by all interest then accrued and unpaid on the principal so prepaid. Any principal or interest prepaid pursuant to this
section shall be in addition to, and not in lieu of, all payments otherwise required to be paid under the Loan Documents at the time of such prepayment. 
 Section 2.8. Initial Availability Amount. The parties hereto agree that the “Initial Availability Amount” for purposes of the definition of “Borrowing Base” shall be an
amount equal to $525,000,000; provided, however, that on the Fairway Acquisition Effective Date, the Borrowing Base will automatically increase to $575,000,000 provided that each of the conditions precedent set forth in Section 4.2 are met on
or before 90 days after the Closing Date. 
 Section 2.9. Determinations of Borrowing Base.

 By each Evaluation Date (or in the case of an Evaluation Date pursuant to clause (a) of the definition
of “Evaluation Date”, within thirty days after such Evaluation Date), Borrower shall furnish to each Lender all information, reports and data which Agent has then requested concerning Restricted Persons’ businesses and properties
(including their oil and gas properties and interests and the reserves and production relating thereto), together with the Engineering Report described in Section 6.2 which is then due, if any; provided that in the case of any “Evaluation
Date” pursuant to clause (a) of the definition thereof, Borrower shall deliver to Agent an Engineering Report of the type described in Section 6.2(e) within thirty days after such Evaluation Date. Within thirty days after receiving
such information, reports and data, Required Lenders shall agree upon an amount for the Borrowing Base, and Agent shall by notice to Borrower designate such amount as the new Borrowing Base available to Borrower hereunder, which designation shall
take effect immediately on the date such notice is sent (herein called a “Determination Date”) and shall remain in effect until but not including the next date as of which the Borrowing Base is redetermined in accordance with the
provisions of this Agreement. If Borrower does not furnish all such information, reports and data by the date specified in the first sentence of this section, Agent may nonetheless designate the Borrowing Base at any amount which Required Lenders
determine and may redesignate the Borrowing Base from time to time thereafter until each Revolving Loan Lender receives all such information, reports and data, whereupon Required Lenders shall designate a new Borrowing Base as described above.
Required Lenders shall determine the amount of the Borrowing Base based upon the loan collateral value which they in their discretion assign to the various oil and gas properties included in the Collateral at the time in question and based upon such
other credit factors 

  
 33 

 
(including without limitation the assets, liabilities, cash flow, hedged and unhedged exposure to price, foreign exchange rate, and interest rate changes, business, properties, prospects,
management and ownership of Borrower and its Affiliates) as they in their discretion deem significant. It is expressly understood that Required Lenders and Agent have no obligation to agree upon or designate the Borrowing Base at any particular
amount, whether in relation to the Commitments or otherwise, and that Revolving Loan Lenders’ commitments to extend credit hereunder is determined by reference to the Borrowing Base from time to time in effect, which Borrowing Base shall be
used to the extent permitted by Law and regulatory authorities, for the purposes of capital adequacy determination and reimbursements under Section 3.2. Should the last day for Required Lenders to redetermine the Borrowing Base in connection
with a particular Evaluation Date be a day other than a Business Day, the period for such redetermination shall be extended to the next succeeding Business Day. 

In the event that a Casualty Event has occurred with respect to any properties or assets of any Restricted Person, to the
extent that the Net Cash Proceeds received by the Borrower or any of its Subsidiaries with respect to such Casualty Event (together with all other Net Cash Proceeds received during such calendar year) exceeds 5% of the Borrowing Base then in effect
and have not been applied or budgeted to be applied by the Borrower or any such Subsidiary to repair, restore or replace the property or asset affected by such Casualty Event within 180 days after the occurrence thereof, which actions the Borrower
or such Subsidiary shall hereby be permitted to take, the Agent, at the request of the Required Lenders, shall have the right to reduce the Borrowing Base, in its reasonable discretion based on its review of such Casualty Event, by the value of the
property or asset so affected by such Casualty Event as set forth in the most recent Engineering Report; provided that, if an Event of Default has occurred and is continuing, (i) such repair, restoration or replacement may occur
only with the written consent of the Agent, (ii) the Agent may, at the request of the Required Lenders, reduce the Borrowing Base in the manner set forth above without regard to the 180 day period referenced above and (iii) such Net Cash
Proceeds shall be applied in accordance with Section 2.7 to the extent required thereby. The Agent shall provide notice to the Borrower and the Lenders of the reduction in the Borrowing Base, which reduction shall be effective as of the date of
such notice. 
 Section 2.10. Maturity Date. Borrower shall repay in full in cash the unpaid
principal amount of all Revolving Loans on the Revolving Loan Maturity Date, or such earlier date as may be required in accordance with the terms hereof. 
 Section 2.11. Letters of Credit. From time to time on any Business Day prior to the end of the Commitment Period, each Issuer will issue, and each Revolving Loan Lender will participate in, to
the extent of each Revolving Loan Lender’s Revolving Loan Percentage Share, the Letters of Credit, in accordance with the following terms: 
 (a) Issuance Requests. By delivering to the Agent and the applicable Issuer an Issuance Request on or before 11:00 a.m., Central time, the Borrower may request, from time to time during the
Commitment Period and on not less than three (3) nor more than ten (10) Business Days’ notice, that such Issuer issue an irrevocable standby letter of credit in such form as may be mutually agreed to by the Borrower and such Issuer
(each a “Letter of Credit”), in support of financial obligations of the Borrower incurred in the Borrower’s ordinary course of business and which are described in such Issuance

  
 34 

 
Request. Upon receipt of an Issuance Request, the Agent shall promptly notify the Revolving Loan Lenders thereof. Each Letter of Credit shall by its terms: (i) be issued in a Stated Amount
which (A) together with all Letter of Credit Outstandings and all outstanding Revolving Loans does not exceed (or would not exceed) the lesser of (1) the then current Borrowing Base or (2) the aggregate Revolving Loan Commitments of
all Revolving Loan Lenders or (B) together with all Letter of Credit Outstandings would not exceed the Letter of Credit Commitment Amount; (ii) be stated to expire on a date (its “Stated Expiry Date”) no later than the
earlier of (A) one year from its date of issuance and (B) the end of the Commitment Period. So long as no Default has occurred and is continuing, by delivery to the applicable Issuer and the Agent of an Issuance Request at least three
(3) but not more than ten (10) Business Days prior to the Stated Expiry Date of any Letter of Credit, the Borrower may request such Issuer to, at such Issuer’s option, extend the Stated Expiry Date of such Letter of Credit for an
additional period not to exceed the earlier of (x) one year from its date of extension or (y) the end of the Commitment Period. 
 No Issuer is under any obligation to issue any Letter of Credit if: (i) any order, judgment or decree of any government agency or arbitrator shall by its terms purport to enjoin or restrain such
Issuer from issuing such Letter of Credit, or any requirement of applicable Law or any request or directive (whether or not having the force of law) from any government agency with jurisdiction over such Issuer shall prohibit, or request that the
Issuer refrain from, the issuance of letters of credit generally or such Letter of Credit in particular or shall impose upon such Issuer with respect to such Letter of Credit any restriction, reserve or capital requirement (for which such Issuer is
not otherwise compensated hereunder) not in effect on the date hereof, or shall impose upon such Issuer any unreimbursed loss, cost or expense which was not applicable on the date hereof and which such Issuer in good faith deems material to it;
(ii) one or more of the applicable conditions contained in Article IV is not then satisfied; (iii) the expiry date of any requested Letter of Credit is prior to the maturity date of any financial obligation to be supported by the requested
Letter of Credit; (iv) any requested Letter of Credit does not provide for drafts, or is not otherwise in form and substance acceptable to such Issuer, or the issuance of a Letter of Credit shall violate any applicable policies of such Issuer;
(v) any standby Letter of Credit is for the purpose of supporting the issuance of any letter of credit by any other Person; or (vi) such Letter of Credit is in a face amount denominated in a currency other than Dollars. The Uniform Customs
and Practice for Documentary Credits most recently published by the International Chamber of Commerce at the time of issuance of any Letter of Credit shall (unless otherwise expressly provided in the Letter of Credit) apply to all Letters of Credit.

 (b) Issuances and Extensions. On the terms and subject to the conditions of this
Agreement (including Article IV), the applicable Issuer shall issue Letters of Credit, and extend the Stated Expiry Dates of outstanding Letters of Credit, in accordance with the Issuance Requests made therefor. Each Issuer will make
available the original of each Letter of Credit which it issues in accordance with the Issuance Request therefor to the beneficiary thereof (and will promptly provide each of the Revolving Loan Lenders and the Borrower with a copy of such Letter of
Credit) and will notify the beneficiary under any Letter of Credit of any extension of the Stated Expiry Date thereof. 

  
 35 

 (c) Existing Letter of Credit. The parties
acknowledge and agree that each letter of credit issued by The Toronto Dominion Bank, New York Branch under the Existing Credit Agreement identified on Item 2.11(c) of the Disclosure Schedule shall be deemed to be a Letter of Credit issued
hereunder by The Toronto Dominion Bank, as an Issuer hereunder, having the same face amount, maturity date and general terms. 
 (d) Other Revolving Loan Lenders’ Participation. Each Letter of Credit issued pursuant to Section 2.11(b) shall, effective upon its issuance and without further action, be issued on
behalf of all Revolving Loan Lenders (including the Issuer thereof) pro rata according to their respective Revolving Loan Percentage Shares. Each Revolving Loan Lender shall, to the extent of its Percentage Share, be deemed irrevocably to have
participated in the issuance of such Letter of Credit and shall be responsible to reimburse promptly the Issuer thereof for Reimbursement Obligations which have not been reimbursed by the Borrower in accordance with Section 2.11(e), or which
have been reimbursed by the Borrower but must be returned, restored or disgorged by such Issuer for any reason, and each Revolving Loan Lender shall, to the extent of its Revolving Loan Percentage Share, be entitled to receive from the Agent a
ratable portion of the Letter of Credit Fee received by the Agent pursuant to Section 2.5(c), with respect to each Letter of Credit. In the event that the Borrower shall fail to reimburse any Issuer, or if for any reason Loans shall not be made
to fund any Reimbursement Obligation, all as provided in Section 2.11(e) and in an amount equal to the amount of any drawing honored by such Issuer under a Letter of Credit issued by it, or in the event such Issuer must for any reason return or
disgorge such reimbursement, such Issuer shall promptly notify each Revolving Loan Lender of the unreimbursed amount of such drawing and of such Revolving Loan Lender’s respective participation therein. Each Revolving Loan Lender shall make
available to such Issuer, whether or not any Default shall have occurred and be continuing, an amount equal to its respective participation in same day or immediately available funds at the office of such Issuer specified in such notice not later
than 11:00 a.m., Central time, on the Business Day (under the laws of the jurisdiction of such Issuer) after the date notified by such Issuer. In the event that any Revolving Loan Lender fails to make available to such Issuer the amount of such
Revolving Loan Lender’s participation in such Letter of Credit as provided herein, such Issuer shall be entitled to recover such amount on demand from such Revolving Loan Lender together with interest at the daily average Federal Funds Rate for
three (3) Business Days (together with such other compensatory amounts as may be required to be paid by such Revolving Loan Lender to the Agent pursuant to the Rules for Interbank Compensation of the council on International Banking or the
Clearinghouse Compensation Committee, as the case may be, as in effect from time to time) and thereafter at the interest rate applicable to ABR Loans plus two percent (2%). Nothing in this Section shall be deemed to prejudice the right of any
Revolving Loan Lender to recover from any Issuer any amounts made available by such Revolving Loan Lender to such Issuer pursuant to this Section in the event that it is determined by a court of competent jurisdiction that the payment with respect
to a Letter of Credit by such Issuer in respect of which payment was made by such Revolving Loan Lender constituted gross negligence or willful misconduct on the part of such Issuer. Each Issuer shall distribute to each other Revolving Loan Lender
which has paid all amounts payable by it under this Section with respect to any Letter of Credit issued by such Issuer such other Revolving Loan Lender’s Percentage Share of all payments received by such Issuer from the Borrower in
reimbursement of drawings honored by such Issuer under such Letter of Credit when such payments are received. 

  
 36 

 (e) Disbursements. Each Issuer will notify the
Borrower and the Agent promptly of the presentment for payment of any Letter of Credit issued by such Issuer, together with notice of the date (the “Disbursement Date”) such payment shall be made. Subject to the terms and provisions
of such Letter of Credit, the applicable Issuer shall make such payment to the beneficiary (or its designee) of such Letter of Credit. Prior to 11:00 a.m., Central time, on the Disbursement Date (or 11:00 a.m., Central time, on the Business Day
following the Disbursement Date if the Borrower shall have received such notice after 10:00 a.m. on the Disbursement Date), the Borrower will reimburse the applicable Issuer for all amounts which it has disbursed under or in respect of such Letter
of Credit. In the event the applicable Issuer is not reimbursed by the Borrower on the Disbursement Date, or if such Issuer must for any reason return or disgorge such reimbursement, the Revolving Loan Lenders shall, on the terms and subject to the
conditions of this Agreement, fund the Reimbursement Obligation therefor by making, on the next Business Day, Revolving Loans which are ABR Loans as provided in Section 2.1 (the Borrower being deemed to have given a timely Borrowing Notice
therefor for such amount); provided, however, for the purpose of determining the availability of the Revolving Loan Commitments to make Revolving Loans immediately prior to giving effect to the application of the proceeds of such
Revolving Loans, such Reimbursement Obligation shall be deemed not to be outstanding at such time. To the extent the applicable Issuer is not reimbursed in full in accordance with the preceding sentences, the Borrower’s Reimbursement Obligation
shall accrue interest at a fluctuating rate determined by reference to the interest rate applicable to ABR Loans, plus a margin of two percent (2%) per annum, payable on demand. 

(f) Reimbursement. The Borrower’s obligation (a “Reimbursement Obligation”)
under Section 2.11(e) to reimburse an Issuer with respect to each Disbursement (including interest thereon), and each Revolving Loan Lender’s obligation to make participation payments in each drawing which has not been reimbursed by the
Borrower, shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim, or defense to payment which the Borrower may have or have had against any Revolving Loan Lender or any beneficiary of a
Letter of Credit, including any defense based upon the occurrence of any Default, any draft, demand or certificate or other document presented under a Letter of Credit proving to be forged, fraudulent, invalid or insufficient, the failure of any
disbursement to conform to the terms of the applicable Letter of Credit (if, in the applicable Issuer’s good faith opinion, such disbursement is determined to be appropriate) or any non-application or misapplication by the beneficiary of the
proceeds of such disbursement, or the legality, validity, form, regularity, or enforceability of such Letter of Credit; provided, however, that nothing herein shall adversely affect the right of the Borrower or any Revolving Loan
Lender to commence any proceeding against the applicable Issuer for any wrongful disbursement made by such Issuer under a Letter of Credit as a result of acts or omissions constituting gross negligence or willful misconduct on the part of such
Issuer. 

  
 37 

 (g) Deemed Disbursements. Upon either (i) the
occurrence and during the continuation of an Event of Default pursuant to Section 8.1(j) or the occurrence of the end of the Commitment Period or (ii) the declaration by the Agent of all or any portion of the outstanding principal amount
of the Loans and other Obligations to be due and payable and/or the commitments (if not theretofore terminated) to be terminated as provided in Section 8.1, an amount equal to that portion of Letter of Credit Outstandings attributable to
outstanding and undrawn Letters of Credit shall, at the election of the applicable Issuer acting on instructions from the Required Lenders, and without demand upon or notice to the Borrower, be deemed to have been paid or disbursed by such Issuer
under such Letters of Credit (notwithstanding that such amount may not in fact have been so paid or disbursed), and, upon notification by such Issuer to the Agent and the Borrower of its obligations under this Section, the Borrower shall be
immediately obligated to reimburse such Issuer the amount deemed to have been so paid or disbursed by such Issuer. Any amounts so received by such Issuer from the Borrower pursuant to this Section shall be held as collateral security for the
repayment of the Borrower’s obligations in connection with the Letters of Credit issued by such Issuer. All amounts on deposit pursuant to this Section 2.11(g) shall, until their application to any Obligation or their return to the
Borrower, as the case may be, at the Borrower’s written request, be invested in high grade short term liquid investments as such Issuer may choose in its sole discretion reasonably exercised, which interest shall be held by the applicable
Issuer as additional collateral security for the repayment of the Borrower’s Obligations under and in connection with the Letters of Credit and all other Obligations. Any losses, net of earnings, and reasonable fees and expenses of such
investments shall be charged against the principal amount invested. No Lender Party shall be liable for any loss resulting from any investment made by such Issuer at the Borrower’s request. Such Issuer is not obligated hereby, or by any other
Loan Document, to make or maintain any investment, except upon written request by the Borrower. At any time when such Letters of Credit shall terminate and all Obligations to each Issuer are either terminated or paid or reimbursed to such Issuer in
full, the Obligations of the Borrower under this Section shall be reduced accordingly (subject, however, to reinstatement in the event any payment in respect of such Letters of Credit is recovered in any manner from such Issuer), and such Issuer
will return to the Borrower the excess, if any, of (A) the aggregate amount held by such Issuer and not theretofore applied by such Issuer to any Reimbursement Obligation over (B) the aggregate amount of all Reimbursement
Obligations to such Issuer pursuant to this Section, as so adjusted. At such time when all Events of Default shall have been cured or waived, if the end of the Commitment Period shall not have occurred for any reason, each Issuer shall return to the
Borrower all amounts then on deposit with such Issuer pursuant to this Section. Borrower hereby assigns and grants to such Issuer a continuing security interest in all such collateral security paid by it to such Issuer, all investments purchased
with such collateral security, and all proceeds thereof to secure its Obligations under this Agreement, the Notes, and the other Loan Documents, and Borrower agrees that collateral security and investments shall be subject to all of the terms and
conditions of the Security Documents. Borrower further agrees that such Issuer shall have all of the rights and remedies of a secured party under the Uniform Commercial Code as adopted in the State of New York with respect to such security interest
and that an Event of Default under this Agreement shall constitute a default for purposes of such security interest. 

  
 38 

 (h) Nature of Reimbursement Obligations. The Borrower
shall assume all risks of the acts, omissions, or misuse of any Letter of Credit by the beneficiary thereof. Neither any Issuer nor any Lender (except to the extent of its own gross negligence or willful misconduct) shall be responsible for:
(i) the form, validity, sufficiency, accuracy, genuineness, or legal effect of any Letter of Credit or any document submitted by any party in connection with the application for and issuance of a Letter of Credit, even if it should in fact
prove to be in any or all respects invalid, insufficient, inaccurate, fraudulent, or forged; (ii) the form, validity, sufficiency, accuracy, genuineness, or legal effect of any instrument transferring or assigning or purporting to transfer or
assign a Letter of Credit or the rights or benefits thereunder or proceeds thereof in whole or in part, which may prove to be invalid or ineffective for any reason; (iii) failure of the beneficiary to comply fully with conditions required in
order to demand payment under a Letter of Credit; (iv) errors, omissions, interruptions, or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex, facsimile or otherwise; (v) any loss or delay in the
transmission or otherwise of any document or draft required in order to make a Disbursement under a Letter of Credit or of the proceeds thereof; (vi) any change in the time, manner or place of payment of, or in any other term of, all or any of
the obligations of the Borrower in respect of any Letter of Credit; (vii) the existence of any claim, set-off, defense or other right that the Borrower may have at any time against any beneficiary or any transferee of any Letter of Credit (or
any Person for whom any such beneficiary or any such transferee may be acting), the Issuer (if other than a Lender or its Affiliates) or any other Person, whether in connection with this Agreement, the transactions contemplated hereby or by the
Letter of Credit or any unrelated transaction; (viii) any payment by an Issuer under any Letter of Credit against presentation of a draft or certificate that does not strictly comply with the terms of any Letter of Credit; or any payment made
by an Issuer under any Letter of Credit to any Person purporting to be a trustee in bankruptcy, debtor-in-possession, assignee for the benefit of creditors, liquidator, receiver or other representative of or successor to any beneficiary or any
transferee of any Letter of Credit, including any arising in connection with any insolvency proceeding; or (ix) any other circumstance or happening whatsoever, whether or not similar to any of the foregoing, including any other circumstance
that might otherwise constitute a defense available to, or a discharge of, the Borrower or a guarantor. None of the foregoing shall affect, impair, or prevent the vesting of any of the rights or powers granted any Issuer or any Lender hereunder. In
furtherance and extension, and not in limitation or derogation, of any of the foregoing, any action taken or omitted to be taken by any Issuer in good faith shall be binding upon the Borrower and shall not put such Issuer under any resulting
liability to the Borrower. 
 (i) Increased Costs; Indemnity. If by reason of (i) any
change in applicable law, regulation, rule, decree or regulatory requirement or any change in the interpretation or application by any judicial or regulatory authority of any law, regulation, rule, decree or regulatory requirement, or
(ii) compliance by any Issuer or any Revolving Loan Lender with any direction, or requirement of any governmental or monetary authority, including, without limitation, Regulation D: (1) any Issuer or any Revolving Loan Lender

  
 39 

 
shall be subject to any tax (other than Indemnified Taxes, Other Taxes and Excluded Taxes), levy, charge or withholding of any nature or to any variation thereof or to any penalty with respect to
the maintenance or fulfillment of its obligations under this Section 2.11, whether directly or by such being imposed on or suffered by such Issuer or such Revolving Loan Lender; (2) any reserve, deposit or similar requirement is or shall
be applicable, increased, imposed or modified in respect of any Letters of Credit issued by any Issuer or participations therein purchased by any Revolving Loan Lender; or (3) there shall be imposed on any Issuer or any Revolving Loan Lender
any other condition regarding this Section 2.11, any Letter of Credit or any participation therein, and the result of the foregoing is directly to increase the cost to such Issuer or such Revolving Loan Lender of issuing or maintaining any
Letter of Credit or of purchasing or maintaining any participation therein, or to reduce any amount receivable in respect thereof by such Issuer or such Revolving Loan Lender, then and in any such case such Issuer or such Revolving Loan Lender may,
at any time after the additional cost is incurred or the amount received is reduced, notify the Agent and the Borrower thereof, and the Borrower shall pay within ten (10) days of demand such amounts as such Issuer or Revolving Loan Lender may
in good faith specify to be necessary to compensate such Issuer or Revolving Loan Lender for such additional cost or reduced receipt, together with interest on such amount from the date demanded until payment in full thereof at a rate equal at all
times to the Alternate Base Rate per annum. The determination by such Issuer or Revolving Loan Lender, as the case may be, of any amount due pursuant to this Section, as set forth in a statement setting forth the calculation thereof in reasonable
detail, shall be rebuttable presumptive evidence of such amounts. 
 In addition to amounts
payable as elsewhere provided in this Section 2.11, the Borrower hereby indemnifies, exonerates and holds each Issuer, the Agent and each other Lender Party harmless from and against any and all actions, causes of action, suits, losses, costs,
liabilities and damages, and expenses incurred in connection therewith (irrespective of whether such Issuer, the Agent or such Lender Party is a party to the action for which indemnification is sought), including reasonable attorneys’ fees and
disbursements, which such Issuer, the Agent or such Lender Party may incur or be subject to as a consequence, direct or indirect, of the issuance of the Letters of Credit, other than, as to each such indemnified party, as a result of the gross
negligence or willful misconduct of such indemnified party, as the case may be, as determined by a court of competent jurisdiction, or the failure of such Issuer to honor a drawing under any Letter of Credit as a result of any act or omission,
whether rightful or wrongful, of any present or future de jure or de facto government or governmental authority. 
 (j) Notwithstanding anything herein to the contrary, no Issuer shall be obligated to issue, renew or extend a Letter of Credit if such Issuer has a good faith belief that any Lender is at such time a
Defaulting Lender hereunder, unless such Issuer has entered into arrangements reasonably satisfactory to such Issuer with the Borrower or such Defaulting Lender to eliminate such Issuer’s risk with respect to such Defaulting Lender. If any
Letter of Credit Outstandings exist at the time a Lender is an Defaulting Lender, the Borrower shall within one Business Day following notice by the Agent cash collateralize such Defaulting Lender’s portion of such Letter of Credit Outstandings
in a manner reasonably satisfactory to such Issuer for so long as such Lender is an Defaulting Lender and such Letter of Credit Outstandings exist. 

  
 40 

 Section 2.12. Interest. So long as no Event of Default has
occurred and is continuing, all ABR Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the Alternate Base Rate in effect on such day. If an Event of Default has
occurred and is continuing, all ABR Loans (exclusive of any past due principal or interest) from time to time outstanding shall bear interest on each day outstanding at the Default Rate in effect on such day. On each ABR Payment Date Borrower shall
pay to the holder hereof all unpaid interest which has accrued on the ABR Loans to but not including such ABR Payment Date. So long as no Event of Default has occurred and is continuing, each Eurodollar Loan (exclusive of any past due principal or
interest) shall bear interest on each day during the related Interest Period at the related Eurodollar Rate in effect on such day. If an Event of Default has occurred and is continuing, each Eurodollar Loan (exclusive of any past due principal or
interest) from time to time outstanding shall bear interest on each day outstanding at the Default Rate in effect on such day. On each Eurodollar Rate Payment Date relating to such Eurodollar Loan, Borrower shall pay to the holder hereof all unpaid
interest which has accrued on such Eurodollar Loan to but not including such Eurodollar Rate Payment Date. All past due principal of and past due interest on the Loans and all other past due Obligations shall bear interest on each day outstanding at
the Default Rate in effect on such day until repaid, and such interest shall be due and payable daily as it accrues. 
 Section 2.13. Register; Notes. The Register shall be maintained on the following terms. 
 (a) The Borrower hereby designates the Agent to serve as the Borrower’s agent, solely for the purpose of this clause, to maintain a register (the “Register”) on which the Agent will
record each Lender’s Commitments, the Loans made by each Lender and each repayment in respect of the principal amount of the Loans, annexed to which the Agent shall retain a copy of each Assignment and Acceptance delivered to the Agent pursuant
to Section 10.6. Failure to make any recordation, or any error in such recordation, shall not affect any Restricted Person’s Obligations. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower,
the Agent and the Lenders shall treat each Person in whose name a Loan is registered as the owner thereof for the purposes of all Loan Documents, notwithstanding notice or any provision herein to the contrary. Any assignment or transfer of a
Commitment or the Loans made pursuant hereto shall be registered in the Register only upon delivery to the Agent of a Assignment and Acceptance that has been executed by the requisite parties pursuant to Section 10.6. No assignment or transfer
of a Lender’s Commitment or Loans shall be effective unless such assignment or transfer shall have been recorded in the Register by the Agent as provided in this Section. 

(b) [Reserved]. 

(c) [Reserved]. 

  
 41 

 (d) The Borrower agrees that, upon the request of any
Revolving Loan Lender, the Borrower will execute and deliver to such Lender a Revolving Loan Note evidencing the Revolving Loans made by, and payable to, such Revolving Loan Lender in a maximum principal amount equal to such Revolving Loan
Lender’s Revolving Loan Percentage Share of the original aggregate Revolving Loan Commitments. The Borrower hereby irrevocably authorizes each Revolving Loan Lender to make (or cause to be made) appropriate notations on the grid attached to
such Revolving Loan Lender’s Note (or on any continuation of such grid), which notations, if made, shall evidence, inter alia, the date of, the outstanding principal amount of, and the interest rate and Interest Period applicable
to the Revolving Loans evidenced thereby. Such notations shall, to the extent not inconsistent with notations made by the Agent in the Register, be conclusive and binding on each Restricted Person absent manifest error; provided that, the
failure of any Revolving Loan Lender to make any such notations shall not limit or otherwise affect any Obligations of any Restricted Person. 
 (e) Interest on each Note shall accrue and be due and payable as provided herein and therein, with Eurodollar Loans bearing interest at the Eurodollar Rate and ABR Loans bearing interest at the Alternate
Base Rate (subject to the applicability of the Default Rate as provided for herein or in the Notes and limited by the provisions of Section 10.9). 
 Section 2.14. Defaulting Lenders. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then 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 2.5(a); 
 (b) the
Commitment of such Defaulting Lender shall not be included in determining whether all Lenders, the Majority Lenders or the Required Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other
modification pursuant to Section 10.1); provided, that (i) such Defaulting Lender’s Commitment may not be increased or extended without its consent and (ii) the principal amount of, or interest or fees payable on, Loans may not
be reduced or excused or the scheduled date of payment may not be postponed as to such Defaulting Lender without such Defaulting Lender’s consent; 

(c) if any Letter of Credit Outstandings exist at the time such Lender becomes a Defaulting Lender then:

 (i) all or any part of the Letter of Credit Outstandings of such Defaulting Lender shall be
reallocated among the non-Defaulting Lenders in accordance with their respective Percentage Shares but only to the extent the sum of all non-Defaulting Lenders’ Facility Usage plus such Defaulting Lender’s Letter of Credit Outstandings
does not exceed the total of all non-Defaulting Lenders’ Commitments; 

  
 42 

 (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 cash collateralize for the benefit of any Issuing Bank only the Borrower’s obligations corresponding to such
Defaulting Lender’s Letter of Credit Outstandings (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.11(g) for so long as such Letter of Credit
Outstandings are outstanding; 
 (iii) if the Borrower cash collateralizes any portion of such
Defaulting Lender’s Letter of Credit Outstandings pursuant to clause (ii) above, the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.5(c) with respect to such Defaulting Lender’s
Letter of Credit Outstandings during the period such Defaulting Lender’s Letter of Credit Outstandings is cash collateralized; 
 (iv) if the Letter of Credit Outstandings of the non-Defaulting Lenders is reallocated pursuant to clause (i) above, then the fees payable to the Lenders pursuant to Section 2.5(a) and
Section 2.5(c) shall be adjusted in accordance with such non-Defaulting Lenders’ Percentage Shares; and 
 (v) if all or any portion of such Defaulting Lender’s Letter of Credit Outstandings are neither reallocated nor cash collateralized pursuant to clause (i) or (ii) above, then, without
prejudice to any rights or remedies of any Issuing Bank or any other Lender hereunder, all letter of credit fees payable under Section 2.5(c) with respect to such Defaulting Lender’s Letter of Credit Outstandings shall be payable to such
Issuing Bank until and to the extent that such Letter of Credit Outstandings is reallocated and/or cash collateralized; and 
 (d) so long as such Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure and the Defaulting
Lender’s then outstanding Letter of Credit Outstandings 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 2.14(c), 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 2.14(c)(i) (and such Defaulting Lender shall not participate therein). 

In the event that the Administrative Agent, the Borrower and the Issuing Banks each agrees that a Defaulting Lender has
adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par
such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage. 

Section 2.15. Reduction of Aggregate Commitments. 

(a) Scheduled Termination of Commitments. Unless previously terminated, the Commitments shall
terminate on the Maturity Date. If at any time the Aggregate Commitments or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or reduction. 

  
 43 

 (b) Optional Termination and Reduction of Aggregate
Credit Amounts. 
 (i) The Borrower may at any time terminate, or from time to time reduce,
the Aggregate Commitments; provided that (i) any such reduction shall apply proportionately and permanently to reduce the Commitments of each of the Lenders, (ii) each reduction of the Aggregate Commitments shall be in an amount that is an
integral multiple of $1,000,000 and (iii) the Borrower shall not terminate or reduce the Aggregate Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.6, the Facility Usage shall not
exceed the lowest of (1) the Borrowing Base in effect as of the date on which the requested reduction is to be made, (2) the Aggregate Commitments or (3) the Facility Amount. 

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the
Aggregate Commitments under Section 2.15(b)(i) at least three Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the
Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section 2.15(b)(ii) shall be irrevocable; provided that a notice of termination of the Aggregate Commitments delivered
by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, 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. Each reduction of the Aggregate Commitments shall be made ratably among the Lenders in accordance with each Lender’s Revolving Loan Percentage Shares. 

ARTICLE III - Payments to Lenders 
 Section 3.1. General Procedures. Unless otherwise expressly provided in a Loan Document, Borrower will make each payment which it owes under the Loan Documents to Agent at its New York office
(in accordance with the then effective wire instructions provided by Agent to Borrower) for the account of the Lender Party to whom such payment is owed. Each such payment must be received by Agent not later than 12:00 noon, New York City time, on
the date such payment becomes due and payable, in lawful money of the United States of America, without set-off, deduction (except for any deduction for Taxes as described in Section 3.6(a)) or counterclaim, and in immediately available funds.
Any payment received by Agent after such time will be deemed to have been made on the next following Business Day. Should any such payment become due and payable on a day other than a Business Day, the maturity of such payment shall be extended to
the next succeeding Business Day, and, in the case of a payment of principal or past due interest, interest shall accrue and be payable thereon for the period of such extension as provided in the Loan Document under which such payment is due. Each
payment under a Loan Document shall be due and payable at the place provided therein and, if no specific place of payment is provided, shall be due and payable at the place of payment of Agent’s New York office or as otherwise directed by
Agent. Agent shall promptly remit in same day funds to 

  
 44 

 
each Lender Party its share, if any, of such payments received by Agent for the account of such Lender Party. Agent may, and upon direction of the Required Lenders shall, apply all amounts
received pursuant to any exercise of remedies under the Loan Documents (including from proceeds of collateral securing the Obligations) or under applicable law upon receipt thereof to the Obligations as follows: 

(a) first, for the payment of all fees and expenses of Agent and its counsel which are then due;

 (b) then for the payment of all other Obligations which are then due (and if such money is
insufficient to pay all such Obligations, first to any reimbursements due Agent under Section 6.9 or 10.4, second to the payment of all interest on the Loans then due on a pro rata basis, third to the payment of all
principal on the Loans and Reimbursement Obligations or cash collateralization in respect of Letters of Credit and all reasonably calculated net credit exposure of any Lender Party under a Hedging Contract with any Restricted Person then due, on a
pro rata basis, and fourth to the payment of all other Obligations then due in proportion to the amounts thereof, or as Lender Parties shall otherwise agree); 

(c) then for the prepayment of principal on any remaining Loans, if any, together with accrued and unpaid
interest on the principal so prepaid; 
 (d) then for the prepayment of any other Obligations, if
any; and 
 (e) last, to the Borrower or any other Person as directed by a court of competent
jurisdiction. 
 All payments applied to principal or interest on any Loan shall be applied first to any interest then due and
payable, then to principal then due and payable, and last to any prepayment of principal and interest in compliance with Sections 2.6 and 2.7. All distributions of amounts described in any of subsections (b), (c) or (d) above shall be made
by Agent pro rata to each Lender Party then owed Obligations described in such subsection (or subclause thereof) in proportion to all amounts owed to all Lender Parties which are described in such subsection (or subclause thereof). 

Section 3.2. Capital Reimbursement. If either (a) the introduction or implementation of or the
compliance with or any change in or in the interpretation of any Law, or (b) the introduction or implementation of or the compliance with any request, directive or guideline from any central bank or other governmental authority (whether or not
having the force of Law) affects or would affect the amount of capital required or expected to be maintained by any Lender Party (or any assignee of such Lender Party) or any corporation controlling any Lender Party (or its assignee), then, upon
demand by such Lender Party, Borrower will pay to Agent for the benefit of such Lender Party, from time to time as specified by such Lender Party, such additional amount or amounts which such Lender Party shall reasonably determine to be appropriate
to compensate such Lender Party or any corporation controlling such Lender Party in light of such circumstances, to the extent that such Lender Party reasonably determines that the amount of any such capital would be increased or the rate of return
on any such capital would be reduced by or in whole or in part based on the existence of the face amount of such Lender Party’s Loans or commitments under this Agreement. 

  
 45 

 Section 3.3. Increased Cost of Eurodollar Loans. If any
applicable Law (whether now in effect or hereinafter enacted or promulgated, including Regulation D) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or
not having the force of Law) (“Change in Law”): 
 (a) shall change the basis of
taxation of payments to any Lender Party of any principal, interest, or other amounts attributable to any Eurodollar Loan or otherwise due under this Agreement in respect of any Eurodollar Loan (other than Indemnified Taxes, Other Taxes and Excluded
Taxes); or 
 (b) shall change, impose, modify, apply or deem applicable any reserve, special
deposit or similar requirements in respect of any Eurodollar Loan (excluding those for which such Lender Party is fully compensated pursuant to adjustments made in the definition of Eurodollar Rate) or against assets of, deposits with or for the
account of, or credit extended by, such Lender Party; or 
 (c) shall impose on any Lender Party
or the interbank eurocurrency deposit market any other condition affecting any Eurodollar Loan, the result of which is to increase the cost to any Lender Party of funding or maintaining any Eurodollar Loan or to reduce the amount of any sum
receivable by any Lender Party in respect of any Eurodollar Loan by an amount deemed by such Lender Party to be material, 

then such Lender Party shall promptly notify Agent and Borrower in writing of the happening of such event and of the amount required to
compensate such Lender Party for such event, whereupon (i) Borrower shall pay such amount to Agent for the account of such Lender Party and (ii) Borrower may elect, by giving to Agent and such Lender Party not less than three Business
Days’ notice, to convert all (but not less than all) of any such Eurodollar Loans into ABR Loans; provided, that notwithstanding anything herein to the contrary, (i) the Dodd-Frank Wall Street Reform and Consumer Protection Act and
all requests, rules, guidelines or directives thereunder or issued in connection therewith and (ii) all requests, rules, guidelines or directives promulgated by any Bank for International Settlements, the Basel Committee on Banking Supervision
(or any successor or similar authority) or the United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to be a Change in Law, regardless of the date enacted, adopted or issued. 

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

  
 46 

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

(a) Any and all payments by or on account of any obligation of the Borrower hereunder shall be made free
and clear of and without deduction for any Taxes except as required by applicable law. If any applicable law requires the deduction or withholding of any Taxes from such payments, then (i) in the case of Indemnified Taxes or Other Taxes, the
sum payable shall be increased as necessary so that after making all required deductions of Indemnified Taxes or Other Taxes (including deductions applicable to additional sums payable under this Section 3.6(a)), the Agent, Lender or Issuer (as
the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (ii) the Borrower shall make all deductions required by applicable law and (iii) the Borrower shall pay the full amount deducted
to the relevant governmental authority in accordance with applicable law. 
 (b) In addition, the
Borrower shall pay any Other Taxes to the relevant governmental authority in accordance with applicable law. 

  
 47 

 (c) The Borrower shall indemnify the Agent, each Lender and
each Issuer within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Agent, such Lender or Issuer, as the case may be, on or with respect to any payment by or on account of any obligation
of the Borrower hereunder (including Indemnified Taxes or Other Taxes imposed or asserted on or attributable to amounts payable under this Section) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto,
whether or not such Indemnified Taxes or Other Taxes were correctly or legally imposed or asserted by the relevant governmental authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender or Issuer,
or by the Agent on its own behalf or on behalf of a Lender or the Issuer, shall be conclusive absent manifest error. 
 (d) As soon as practicable after any payment of Indemnified Taxes or Other Taxes by the Borrower to a governmental authority, the Borrower shall deliver to the Agent the original or a certified copy of a
receipt issued by such governmental authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Agent. 

(e) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to
payments made under any Loan Document shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law or reasonably requested by the Borrower or the Agent, 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. In addition, any Lender, if requested by the Borrower or the Agent, shall deliver
such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Agent as will enable the Borrower or the Agent to determine whether or not such Lender is subject to backup withholding or information reporting
requirements. 
 Without limiting the generality of the foregoing, any Foreign Lender shall deliver to the
Borrower and the 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 request of the Borrower or
the Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: 
 (A) in the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect to payments of interest under any 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; 

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

  
 48 

 (C) 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 to the effect that (i) such Foreign is not a “bank” within the meaning of Section 881(c)(3)(A) of the Code, a “10 percent
shareholder” of the Borrower within the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C) of the Code and (ii) the interest payments in question are not
effectively connected with a U.S. trade or business conducted by such Foreign Lender and (y) executed originals of IRS Form W-8BEN; and 
 (D) 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 Agent to determine the withholding or deduction required to be made. 

(E) 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 Agent
at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the 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 Agent as may be necessary for the Borrower and the 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. 

(f) If the Agent, a Lender or an Issuer determines, in its reasonable discretion, that it has received a
refund of any Indemnified Taxes or Other Taxes as to which it has been indemnified by the Borrower or with respect to which the Borrower has paid additional amounts pursuant to this Section 3.6, it shall pay over such refund to the Borrower
(but only to the extent of indemnity payments made, or additional amounts paid, by the Borrower under this Section 3.6 with respect to the Indemnified Taxes or Other Taxes giving rise to such refund), net of all out-of-pocket expenses of the
Agent, such Lender or such Issuer and without interest (other than any interest paid by the relevant governmental authority with respect to such refund); provided, that the Borrower, upon the request of the Agent, such Lender, or such Issuer agrees
to repay the amount paid over to the Borrower (plus any penalties, interest or other charges imposed by the relevant governmental authority) to the Agent, such Lender or such Issuer in the event the Agent or such Lender is required to repay such
refund to such governmental authority. 

  
 49 

 Section 3.7. Change of Applicable Lending Office. Each
Lender Party agrees that, upon the occurrence of any event giving rise to the operation of any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 with respect to such Lender Party, it will, if requested by Borrower, use reasonable efforts (subject to overall
policy considerations of such Lender Party) to designate another Lending Office, provided that such designation is made on such terms that such Lender Party and its Lending Office suffer no economic, legal or regulatory disadvantage, with the object
of avoiding the consequence of the event giving rise to the operation of any such section. Nothing in this section shall affect or postpone any of the obligations of Borrower or the rights of any Lender Party provided in any of Sections 3.2, 3.3,
3.4, 3.5 or 3.6. 
 Section 3.8. Replacement of Lenders. If any Lender Party seeks reimbursement for
increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, or if any Lender Party becomes a Non-Consenting Lender pursuant to Section 10.1 or a Defaulting Lender, then within ninety days thereafter and provided no Event of Default then
exists, Borrower shall have the right (unless such Lender Party withdraws its request for additional compensation) to replace such Lender Party, Non-Consenting Lender or Defaulting Lender by requiring such Lender Party, Non-Consenting Lender or
Defaulting Lender to assign its Loans, Notes and its Commitments hereunder to an Eligible Transferee reasonably acceptable to Agent and to Borrower, provided that: (i) all Obligations of Borrower owing to such Lender Party, Non-Consenting
Lender or Defaulting Lender being replaced (including such increased costs, but excluding principal and accrued interest on the Notes being assigned) shall be paid in full to such Lender Party, Non-Consenting Lender or Defaulting Lender concurrently
with such assignment, and (ii) the replacement Eligible Transferee shall purchase the Loans, Notes and Commitments being assigned by paying to such Lender Party, Non-Consenting Lender or Defaulting Lender a price equal to the principal amount
thereof plus applicable reimbursement obligations in respect of Letters of Credit, if any, plus accrued and unpaid interest thereon. In connection with any such assignment Borrower, Agent, such Lender Party, Non-Consenting Lender or
Defaulting Lender and the replacement Eligible Transferee shall otherwise comply with Section 10.6. Notwithstanding the foregoing rights of Borrower under this section, however, Borrower may not replace any Lender Party which seeks
reimbursement for increased costs under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, unless Borrower is at the same time replacing all Lender Parties which are then seeking such compensation. In connection with any such replacement of a Lender Party,
Non-Consenting Lender or Defaulting Lender, Borrower shall pay all outstanding and unpaid costs and expenses due to such Lender Party, Non-Consenting Lender or Defaulting Lender hereunder (including costs and expenses that would have been due to
such Lender Party pursuant to Section 3.5 if such Lender Party’s, Non-Consenting Lender’s or Defaulting Lender’s Loans had been prepaid) at the time of such replacement. 

Section 3.9. Participants. If a Lender has assigned a participation in its Loans or commitment hereunder to
another Person in accordance with Section 10.6, any amount otherwise payable by Borrower to such Lender under Section 3.3 through 3.6 (in this section called “Increased Costs”), shall include that portion of the Increased
Costs determined by such Lender to be allocable to the amount of any interest or participation transferred by such Lender in such Lender’s Loan or commitments under this Agreement; provided that, for the avoidance of doubt, the amount of the
Increased Costs shall not exceed the amount that would be due if such Lender had not assigned any participation.

properties and obligations and to induce each Lender Party to enter into this Agreement and to extend credit hereunder, Borrower represents and warrants to each Lender Party that: 

  
 54 

 Section 5.1. No Default. No Restricted Person is in default in
the performance of any of the covenants and agreements contained in any Loan Document. No event has occurred and is continuing which constitutes a Default. 
 Section 5.2. Organization and Good Standing. Each Restricted Person is duly organized, validly existing and in good standing under the Laws of its jurisdiction of organization, having all
powers and governmental approvals required to carry on its business and enter into and carry out the transactions contemplated hereby. Each Restricted Person is duly qualified, in good standing, and authorized to do business in all other
jurisdictions within the United States wherein the character of the properties owned or held by it or the nature of the business transacted by it makes such qualification necessary. Each Restricted Person has taken all actions and procedures
customarily taken in order to enter, for the purpose of conducting business or owning property, each jurisdiction outside the United States wherein the character of the properties owned or held by it or the nature of the business transacted by it
makes such actions and procedures desirable. 
 Section 5.3. Authorization. Each Restricted Person
has duly taken all action necessary to authorize the execution and delivery by it of the Loan Documents to which it is a party and to authorize the consummation of the transactions contemplated thereby and the performance of its obligations
thereunder. Borrower is duly authorized to borrow funds hereunder. 
 Section 5.4. No Conflicts or
Consents. The execution and delivery by the various Restricted Persons of the Loan Documents to which each is a party, the performance by each of its obligations under such Loan Documents and the consummation of the transactions contemplated by
the various Loan Documents, do not and will not (a) conflict with any provision of (i) any Law, (ii) the organizational documents of any Restricted Person, or (iii) any agreement, judgment, license, order or permit applicable to
or binding upon any Restricted Person other than, in the case of (i) and (iii), such conflicts that could not reasonably be expected to cause a Material Adverse Change, (b) result in the acceleration of any Indebtedness owed by any
Restricted Person, or (c) result in or require the creation of any Lien upon any assets or properties of any Restricted Person except as expressly contemplated in the Loan Documents. Except for those which have already been obtained or as
expressly contemplated in the Loan Documents, no consent, approval, authorization or order of, and no notice to or filing with, any Tribunal or third party is required in connection with the execution, delivery or performance by any Restricted
Person of any Loan Document or to consummate any transactions contemplated by the Loan Documents.

general application relating to the enforcement of creditors’ rights. 
 Section 5.6. Initial
Financial Statements. Borrower has heretofore delivered to each Lender Party true, correct and complete copies of the Initial Financial Statements. The Initial Financial Statements fairly present Borrower’s Consolidated financial position
at the respective dates thereof and the Consolidated results of Borrower’s operations and Borrower’s 

  
 55 

 
Consolidated cash flows for the respective periods thereof. Since the date of the audited Initial Financial Statements no Material Adverse Change has occurred, except as reflected in the

instrument or restriction which could cause a Material Adverse Change. 
 Section 5.8. Full

hereby contains any untrue statement of a material fact or omits to state any material fact known to any Restricted Person (other than industry-wide risks normally associated with the types of businesses conducted by Restricted Persons) necessary to
make the statements contained herein or therein not misleading in any material respect as of the date made or deemed made. There is no fact known to any Restricted Person (other than industry-wide risks normally associated with the types of
businesses conducted by Restricted Persons) that has not been disclosed to each Lender Party in writing which could cause a Material Adverse Change. There are no statements or conclusions in any Engineering Report which are based upon or include
misleading information or fail to take into account material information regarding the matters reported therein, it being understood that each Engineering Report is necessarily based upon professional opinions, estimates and projections and that
Borrower does not warrant that such opinions, estimates and projections will ultimately prove to have been accurate. Borrower has heretofore delivered to each Lender Party true, correct and complete copies of the Initial Engineering Reports.

Adverse Change, 
 (d) the occurrence of any Termination Event,

all controversies on account of any of the foregoing. Borrower will also notify Agent and Agent’s counsel in writing at least twenty Business Days prior to the date that any Restricted Person changes its name or the location of its chief
executive office or principal place of business or the place where it keeps its books and records concerning the Collateral, furnishing with such notice any necessary financing statement amendments or requesting Agent and its counsel to prepare the
same. 
 Section 6.5. Maintenance of Properties. Each Restricted Person will maintain, preserve,
protect, and keep all Collateral and all other property used or useful in the conduct of its business in good condition in accordance with oil and gas industry standards and in compliance in all material respects with all applicable Laws, and will

contesting the validity thereof by appropriate proceedings (promptly instituted and diligently concluded) and has set aside on its books adequate reserves therefor, or to the extent any such failure to pay or discharge any of the foregoing would not
result in a Material Adverse Change. 
 Section 6.8. Insurance. Each Restricted Person will keep or
cause to be kept insured by financially sound and reputable insurers its property in accordance with the Insurance Schedule and will at all times maintain or cause to be maintained insurance covering such risks as are customarily carried, or
self-insured, by businesses similarly situated. All loss payable clauses or provisions in all policies of insurance maintained by the Borrower described in the Insurance Schedule shall be endorsed in favor of and made payable to the Agent for the
ratable benefit of the Lender Parties, as their interests may appear. In addition, the Agent on behalf of the Lender Parties shall be named (a) as additional insured with a waiver of subrogation on all of the Restricted Persons’ liability
insurance policies maintained by the Borrower with respect to all or any portion of the Collateral, and (b) as loss payee on all of the Restricted Persons’ casualty and property insurance policies covering all or any portion of the

an Event of Default, the Agent (i) shall have the right, for the benefit of the Lender Parties, to retain, and the Borrower hereby assigns to the Agent for the benefit of the Lender Parties, any and all monies that may become payable under any
such policies of insurance by reason of damage, loss or destruction of any Collateral for the Obligations or any part thereof, and (ii) may, at its election, either apply for the benefit of the Lender Parties all or any part of the sums so
collected in accordance with the Loan Documents toward payment of the Obligations, whether or not such Obligations are then due and payable, in such manner as the Agent may elect, or release same to the applicable Restricted Person. 

Section 6.9. Performance on Borrower’s Behalf. If any Restricted Person fails to pay any taxes,
insurance premiums, expenses, attorneys’ fees or other amounts it is required to pay under any Loan Document, Agent may pay the same. Borrower shall immediately reimburse Agent for any such payments and each amount paid by Agent shall
constitute an Obligation owed hereunder which is due and payable on the date such amount is paid by Agent.

respect to an alleged Release of Hazardous Materials arising out of the operations of any of the Restricted Persons (including any costs to investigate or remediate such Release) if the Borrower reasonably anticipates that any of such actions will
result in liability to the Restricted Persons of $5,000,000 or more, not fully covered by insurance, subject to normal deductibles. 
 (d) The Borrower will provide to Agent environmental assessments and tests in accordance with the most current version of applicable American Society of Testing Materials standards upon the reasonable
request by the Agent upon an Event of Default under this Agreement (or as otherwise required to be obtained by the Agent or the Lenders by any Tribunal), in connection with any material real properties of the Restricted Persons. 

(e) Concurrent with the furnishing of financial statements pursuant to Section 6.2(a), Borrower will
furnish to Agent a reasonably detailed written description of all material: (i) citations, civil or criminal penalty assessments, or compliance orders with

 Section 6.14. Hedging Program. Subject to the provisions of Section 7.3,
the Borrower shall not assign, terminate or unwind any of the Hedging Contracts reflected in the hedging positions set forth on a certificate delivered pursuant to Section 6.2(a) or sell any of such Hedging Contracts if the effect of such
action (when taken together with any other Hedging Contracts executed contemporaneously with the taking of such action) would have the effect of canceling its positions under such Hedging Contracts unless such actions (a) are undertaken
(i) with prior written notice to and approval from (which approval shall not be unreasonably withheld or delayed) the Agent and (ii) for the purpose of repositioning volumes for later or earlier months, for the purpose of eliminating
production obligations in anticipation of temporary production shutdowns due to storms or other force majeure events, for the purpose of eliminating production obligations while maintaining hedge volumes and minimum prices for the Borrower or any of
its Subsidiaries or for the purpose of placing such obligations under other Hedging Contracts that provide higher minimum prices for the Borrower or any of its Subsidiaries, and (b) are in compliance with the restrictions set forth in
Section 7.3. As of the date of any determination or redetermination of the Borrowing Base, the Borrower shall maintain hedging positions that are acceptable to the Agent, acting reasonably.

percent (80%) of the total value of the oil and gas reserves of the Restricted Persons and at least eighty percent (80%) of the total value of the proved developed producing reserves of the Restricted Persons (in this section called the
“Required Percentages”); provided that if, immediately following the delivery of an Engineering Report and only to the extent that the Borrower in good faith believed that it was not in breach of this Section 6.15 immediately
prior to receiving a copy of such Engineering Report, Borrower shall determine that the Mortgaged Properties do not constitute the Required Percentages of oil and gas reserves or proved developed producing reserves as required in this
Section 6.15, Borrower shall have the thirty (30) day period described in Section 6.2(f) to execute and deliver documentation in form and substance satisfactory to Agent, granting to Agent first perfected Liens subject to Permitted
Liens on oil and gas properties that are not then part of the Mortgaged Properties, sufficient to cause the Mortgaged Properties to include the Required Percentages. In addition, Borrower will furnish to Agent title due diligence in form and
substance satisfactory to Agent and will furnish all other documents and information relating to such properties as Agent may reasonably request. 

  
 67 

 Section 6.16. Perfection and Protection of Security Interests and
Lions. Borrower will from time to time deliver, and will cause each other Restricted Person from time to time to deliver, to Agent any financing statements, continuation statements, extension agreements and other documents, properly completed
and executed (and acknowledged when required) by Restricted Persons in form and substance satisfactory to Agent, which Agent requests for the purpose of perfecting, confirming, or protecting any Liens or other rights in Collateral securing any
Obligations. At the time of recording of the Security Documents, counsel for Borrower shall conduct searches of the lien, judgment, litigation and UCC records of the counties and offices where such documents are filed and promptly upon receipt
thereof from such offices forward such searches to Agent’s counsel together with the original recorded Security Documents and file stamped copies of the related financing statements. 

Section 6.17. Bank Accounts; Offset. To secure the repayment of the Obligations Borrower hereby grants to
each Lender Party a security interest, a lien, and a right of offset, each of which shall be in addition to all other interests, liens, and rights of any Lender Party at common law, under the Loan Documents, or otherwise, and each of which shall be
upon and against (a) any and all moneys, securities or other property (and the proceeds therefrom) of Borrower now or hereafter held or received by or in transit to any Lender Party from or for the account of Borrower, whether for safekeeping,
custody, pledge, transmission, collection or otherwise, (b) any and all deposits (general or special, time or demand, provisional or final) of Borrower with any Lender Party, and (c) any other credits and claims of Borrower at any time
existing against any Lender Party, including claims under certificates of deposit. At any time and from time to time after the occurrence of any Default, each Lender Party is hereby authorized to foreclose upon, or to offset against the Obligations
then due and payable (in either case without notice to Borrower), any and all items herein above referred to. The remedies of foreclosure and offset are separate and cumulative, and either may be exercised independently of the other without regard
to procedures or restrictions applicable to the other. 
 Section 6.18. Production Proceeds.
Notwithstanding that, by the terms of the various Security Documents, the grantors thereunder are and will be assigning to Agent for the benefit of the Lender Parties all of the “Production Proceeds” (as defined therein and in this section
collectively called “Proceeds”) accruing to the property covered thereby, so long as no Default has occurred such Persons may continue to receive from the purchasers of production all such Proceeds, subject, however, to the Liens
created under the Security Documents, which Liens are hereby affirmed and ratified. Upon the occurrence of a Default, Agent and Lenders may exercise all rights and remedies granted under the Security Documents, including the right to obtain
possession of all Proceeds then held by Restricted Persons or to receive directly from the purchasers of production all other Proceeds. In no case shall any failure, whether purposed or inadvertent, by Agent or Lenders to collect directly any such
Proceeds constitute in any way a waiver, remission or release of any of their rights under the Security Documents, nor shall any release of any Proceeds by Agent or Lenders to Restricted Persons constitute a waiver, remission, or release of any
other Proceeds or of any rights of Agent or Lenders to collect other Proceeds thereafter. 

  
 68 

 Section 6.19. Guaranties of Borrower’s Subsidiaries; Joinder;
Non-Guarantor Subsidiaries. (a) Each Subsidiary of Borrower (other than a Non-Guarantor Subsidiary) shall, promptly upon request by Agent, execute and deliver to Agent an absolute and unconditional guaranty of the timely repayment of the
Obligations and the due and punctual performance of the obligations of Borrower hereunder, which guaranty shall be satisfactory to Agent in form and substance. Borrower will cause each of its Subsidiaries to deliver to Agent, simultaneously with its
delivery of such a guaranty, written evidence satisfactory to Agent and its counsel that such Subsidiary has taken all action necessary to duly approve and authorize its execution, delivery and performance of such guaranty and any other documents
which it is required to execute and to cause each of its Subsidiaries (other than Non-Guarantor Subsidiaries) to execute a joinder to the Subsidiary Security Agreement (as defined in the Security Schedule) or otherwise provide a security agreement
in form and substance acceptable to the Agent. 
 (b) No Subsidiary of Borrower shall be a Non-Guarantor
Subsidiary unless it is designated as such in the Disclosure Schedule as of the Closing Date of this Agreement or otherwise designated as such in a written notice by Borrower to Agent in compliance with Section 6.19(b). Borrower may designate
by written notification thereof to the Agent, any Subsidiary, including a newly formed or newly acquired Subsidiary, as a Non-Guarantor Subsidiary if (i) prior, and after giving effect, to such designation, neither a Default nor a Borrowing
Base Deficiency would exist, and (ii) such Subsidiary has assets of less than $5,000,000 as of the later to occur of the last day of the immediately preceding Fiscal Quarter and the date such Subsidiary was acquired or formed by Borrower.
Borrower shall not permit the aggregate principal amount of all Non-Recourse Debt of all Non-Guarantor Subsidiaries outstanding at any one time to exceed $50,000,000. 

Section 6.20. Casualty and Condemnation. The Borrower will furnish to the Agent promptly, and in any event
within fifteen (15) Business Days, after an Authorized Officer of the Borrower becoming aware of the occurrence, written notice of any Casualty Event to any Collateral or the commencement of any action or proceeding for the taking of any
material portion of the Collateral or any part thereof or interest therein under power of eminent domain or by condemnation or similar proceeding, to the extent the fair market value of such Collateral so affected, when aggregated with the fair
market value of all other Collateral so affected by a Casualty Event occurring in the same calendar year, exceeds 5% of the Borrowing Base then in effect. 
 Section 6.21. ERISA Information. As soon as available, and in any event, within 10 days after the Borrower obtains knowledge of any of the following, the Borrower will furnish and will cause
each ERISA Affiliate to promptly furnish to the Agent with sufficient copies to the Lenders (a) a written notice signed by an Authorized Officer describing the occurrence of any Termination Event in connection with any ERISA Plan or any trust
created thereunder, and specifying what action the Borrower or 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, (b) copies of any notice of the PBGC’s institution of proceedings to terminate or to have a trustee appointed to administer any ERISA Plan and (c) a written notice of the Borrower’s or an ERISA
Affiliate’s participation in a “multiemployer plan” as defined in Section 4001 of ERISA.

Agent hereby undertakes, to receive payments of principal, interest and other amounts due hereunder as specified herein and to take all other actions and to exercise such powers under the Loan Documents as are specifically delegated to Agent by the
terms hereof or thereof, together with all other powers reasonably incidental thereto. The relationship of Agent to the other Lender Parties is only that of one commercial lender acting as administrative agent for others, and nothing in the Loan
Documents shall be construed to constitute Agent a trustee or other fiduciary for any holder of any of the Notes or of any participation therein nor to impose on Agent duties and obligations other than those expressly provided for in the Loan
Documents. With respect to any matters not expressly provided for in the Loan Documents and any matters which the Loan Documents place within the discretion of Agent, Agent shall not be required to exercise any discretion or take any action, and it
may request instructions from Lenders with respect to any such matter, in which case it shall be required to act or to refrain from acting (and shall be fully protected and free from liability to all Lenders in so acting or refraining from acting)
upon the instructions of Required Lenders (including itself), provided, however, that Agent shall not be required to take any action which exposes it to a risk of personal liability that it considers unreasonable or which is contrary to the Loan
Documents or to applicable Law. Upon receipt by Agent from Borrower of any communication calling for action on the part of Lenders or upon notice from any other Lender Party to Agent of any Default or Event of Default, Agent shall promptly notify
each other Lender Party thereof. 
 Section 9.2. Exculpation, Agent’s Reliance, Etc. Neither
Agent nor any Issuer nor any of their directors, officers, agents, attorneys, or employees shall be liable for any action taken or omitted to be taken by any of them under or in connection with the Loan Documents, INCLUDING THEIR NEGLIGENCE OF
ANY KIND, except that each shall be liable for its own gross negligence or willful misconduct. Without limiting the generality of the foregoing, Agent and Issuers (a) may treat the payee of any Note as the holder thereof until Agent
receives written notice of the assignment or transfer thereof in accordance with this Agreement, signed by such payee and in form satisfactory to Agent; (b) may consult with legal counsel (including counsel for Borrower), independent public
accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representation
to any other Lender Party and shall not be responsible to any other Lender Party for any statements, warranties or representations made in or in connection with the Loan Documents; (d) shall not have any duty to ascertain or to inquire as to
the performance or observance of any of the terms, covenants or conditions of the Loan Documents on the part of any Restricted Person or to inspect the property (including the books and records) of any Restricted Person; (e) shall not be
responsible to any other Lender Party for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of any Loan Document or any instrument or document furnished in connection therewith; (f) may rely upon the
representations and warranties of each Restricted Person and the Lenders in exercising its powers hereunder; and (g) shall incur no liability under or in respect of the Loan Documents by acting upon any notice, consent, certificate or other

 81 

 Section 9.3. Credit Decisions. Each Lender Party acknowledges
that it has, independently and without reliance upon any other Lender Party, made its own analysis of Borrower and the transactions contemplated hereby and its own independent decision to enter into this Agreement and the other Loan Documents. Each
Lender Party also acknowledges that it will, independently and without reliance upon any other Lender Party and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or
not taking action under the Loan Documents. 
 Section 9.4. Indemnification. Each Lender agrees to
indemnify Agent (to the extent not reimbursed by Borrower within ten (10) days after demand) from and against such Lender’s Aggregate Percentage Share of any and all liabilities, obligations, claims, losses, damages, penalties, fines,
actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature whatsoever (in this section collectively called “liabilities and
costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against Agent growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions
and events (including the enforcement thereof) at any time associated therewith or contemplated therein (including any Environmental Claims or violation or noncompliance with any Environmental Laws by any Person or any liabilities or duties of any
Person with respect to the presence or Release of Hazardous Materials found in or released into the environment). Each Lender agrees to indemnify Issuers (to the extent not reimbursed by Borrower within ten (10) days after demand) from and
against such Lender’s Aggregate Percentage Share of any and all liabilities and costs which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Issuer growing out of, resulting from or in any other way
associated with the Letters of Credit issued by such Issuer. For the avoidance of doubt, any indemnification relating to Taxes shall be covered exclusively by Section 3.6 and shall not be covered by this Section 9.4. 

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR
IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT OR ISSUER, 
 provided only that no Lender shall be obligated under this section to indemnify Agent and any Issuer for that portion, if any, of any liabilities and costs which is proximately caused by Agent’s own
individual gross negligence or willful misconduct, as determined in a final judgment. Cumulative of the foregoing, each Lender agrees to reimburse Agent and such Issuer promptly upon demand for such Lender’s Aggregate Percentage Share of any
costs and expenses to be paid to Agent or such Issuer by Borrower under Section 10.4(a) to the extent that Agent or such Issuer is not timely reimbursed for such expenses by Borrower as provided in such section. As used in this section the
terms “Agent” and “Issuer” shall refer not only to the Person designated as such in Section 1.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Person.

 Section 9.5. Rights as Lender. In its capacity as a Lender,
Agent and each Issuer shall have the same rights and obligations as any Lender and may exercise such rights as though it were not Agent. Agent or any Issuer may accept deposits from, lend money to, act as Trustee under indentures of, and generally
engage in any kind of business with any Restricted Person or their Affiliates, all as if it were not Agent or an Issuer hereunder and without any duty to account therefor to any other Lender. 

Section 9.6. Sharing of Set-Offs and Other Payments. Each Lender Party agrees that if it shall, whether
through the exercise of rights under Security Documents or rights of banker’s lien, set off, or counterclaim against Borrower or otherwise, obtain payment of a portion of the aggregate Obligations owed to it which, taking into account all
distributions made by Agent under Section 3.1, causes such Lender Party to have received more than it would have received had such payment been received by Agent and distributed pursuant to Section 3.1, then (a) it shall be deemed to
have simultaneously purchased and shall be obligated to purchase interests in the Obligations as necessary to cause all Lender Parties to share all payments as provided for in Section 3.1, and (b) such other adjustments shall be made from
time to time as shall be equitable to ensure that Agent and all Lenders share all payments of Obligations as provided in Section 3.1; provided, however, that nothing herein contained shall in any way affect the right of any Lender Party to
obtain payment (whether by exercise of rights of banker’s lien, set-off or counterclaim or otherwise) of indebtedness other than the Obligations. Borrower expressly consents to the foregoing arrangements and agrees that any holder of any such
interest or other participation in the Obligations, whether or not acquired pursuant to the foregoing arrangements, may to the fullest extent permitted by Law exercise any and all rights of banker’s lien, set-off, or counterclaim as fully as if
such holder were a holder of the Obligations in the amount of such interest or other participation. If all or any part of any funds transferred pursuant to this section is thereafter recovered from the seller under this section which received the
same, the purchase provided for in this section shall be deemed to have been rescinded to the extent of such recovery, together with interest, if any, if interest is required pursuant to Tribunal order to be paid on account of the possession of such
funds prior to such recovery. 
 Section 9.7. Investments. Whenever Agent in good faith determines
that it is uncertain about how to distribute to Lenders any funds which it has received, or whenever Agent in good faith determines that there is any dispute among Lenders about how such funds should be distributed, Agent may choose to defer
distribution of the funds which are the subject of such uncertainty or dispute. If Agent in good faith believes that the uncertainty or dispute will not be promptly resolved, or if Agent is otherwise required to invest funds pending distribution to
Lenders, Agent shall invest such funds pending distribution, and all interest on any such investment shall be distributed upon the distribution of such investment and in the same proportion and to the same Persons as such investment; provided that
Agent shall not be liable to Lenders for any loss on such investment except for its gross negligence or willful misconduct (BUT INCLUDING FOR ITS NEGLIGENCE), as determined in a final judgment. All moneys received by Agent for distribution to
Lenders (other than to the Person who is Agent in its separate capacity as a Lender) shall be held by Agent pending such distribution solely as Agent for such Lenders, and Agent shall have no equitable title to any portion thereof. 

Section 9.8. Benefit of Article IX. The provisions of this Article (other than the following
Section 9.9) are intended solely for the benefit of Lender Parties, and no Restricted Person shall be entitled to rely on any such provision or assert any such provision in a claim or defense against any Lender Party. Lender Parties may waive
or amend such provisions as they desire without any notice to or consent of Borrower or any Restricted Person. 

  
 83 

 Section 9.9. Resignation. Agent or any Issuer may resign at any
time by giving written notice thereof to Lenders and Borrower. Each such notice shall set forth the date of such resignation. Required Lenders shall have the right to appoint a successor Agent or, if such resigning Issuer is the sole issuer
hereunder, Issuer. A successor must be appointed for any retiring Agent (or a retiring Issuer if such Issuer is the sole Issuer hereunder), and such Agent’s (or Issuer’s) resignation shall become effective when such successor accepts such
appointment. If, within thirty days after the date of the retiring Agent’s (or Issuer’s) resignation, no successor Agent (or Issuer, if such Issuer is the sole Issuer hereunder) has been appointed and has accepted such appointment, then
the retiring Agent (or Issuer) may appoint a successor Agent (or Issuer), which shall be a financial institution organized under the Laws of the United States of America or of any state thereof. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent or Issuer, the retiring Agent or Issuer shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent’s or Issuer’s resignation hereunder the
provisions of this Article IX shall continue to inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent or Issuer under the Loan Documents. 
 ARTICLE X - Miscellaneous  
 Section 10.1. Waivers and
Amendments; Acknowledgments. 
 (a) Waivers and Amendments. No failure or delay (whether
by course of conduct or otherwise) by any Lender Party in exercising any right, power or remedy which such Lender Party may have under any of the Loan Documents shall operate as a waiver thereof or of any other right, power or remedy, nor shall any
single or partial exercise by any Lender Party of any such right, power or remedy preclude any other or further exercise thereof or of any other right, power or remedy. No waiver of any provision of any Loan Document and no consent to any departure
therefrom shall ever be effective unless it is in writing and signed as provided below in this section, and then such waiver or consent shall be effective only in the specific instances and for the purposes for which given and to the extent
specified in such writing. No notice to or demand on any Restricted Person shall in any case of itself entitle any Restricted Person to any other or further notice or demand in similar or other circumstances. This Agreement and the other Loan
Documents set forth the entire understanding between the parties hereto with respect to the transactions contemplated herein and therein and supersede all prior discussions and understandings with respect to the subject matter hereof and thereof,
and no waiver, consent, release, modification or amendment of or supplement to this Agreement or the other Loan Documents shall be valid or effective against any party hereto unless the same is in writing and signed by (i) if such party is
Borrower, by Borrower, (ii) if such party is Agent, by such party, (iii) if such party is a Lender, by such Lender or by Agent on behalf of Lenders with the written consent of Majority Lenders (which consent has already been given as to
the termination of the Loan Documents as provided in Section 10.14) and (iv) if such party is Issuer, by Issuer. Notwithstanding the foregoing or anything to the contrary herein, Agent shall not,

  
 84 

 
without the prior consent of each individual Lender, execute and deliver on behalf of such Lender any waiver or amendment which would: (1) waive any of the conditions specified in Article IV
(provided that Agent may in its discretion withdraw any request it has made under Section 4.2(e)), (2) increase the Commitment of such Lender or subject such Lender to any additional obligations, (3) reduce any fees payable to such
Lender hereunder, or the principal of, or interest on, such Lender’s Note, (4) postpone any date fixed for any payment of any such fees, principal or interest, (5) increase the Facility Amount or the Aggregate Commitments of the
Lenders to an amount in either case in excess of $900,000,000 or increase the aggregate amount of the Revolving Loan Commitments or amend the definition herein of “Majority Lenders” or “Required Lenders” or otherwise change the
aggregate amount of applicable Percentage Shares which is required for Agent, Lenders or any of them to take any particular action under the Loan Documents, (6) release Borrower from its obligation to pay such Lender’s Note,
(7) release all or substantially all of the Collateral or (8) amend this Section 10.1, or (9) amend Section 9.6. Notwithstanding the foregoing, (A) to the extent that the Borrower or any Restricted Person transfers,
sells or otherwise assigns any Collateral in accordance with the Loan Documents, the Agent is authorized to release the Agent’s and Lenders’ Liens on such Collateral without any further consent by any of the Lender Parties; (B) any
amendment of the definition of “Initial Availability Amount” or any proposed amendment, modification, waiver or termination of any provision with respect to any determination or redetermination of the Borrowing Base, or in connection with
any matter directly relating to the Borrowing Base (including matters in respect of any Borrowing Base Deficiency and in respect of the relevant provisions of Section 7.5 relating to the Borrowing Base), shall only require the consent of the
Revolving Loan Lenders whose Revolving Loan Percentage Shares equal or exceed sixty-six and two-thirds percent (66-2/3%) (except that any amendment that increases the Initial Availability Amount or then current Borrowing Base shall require the
consent of all of the Revolving Loan Lenders; provided, however that the increase in the Initial Availability Amount in connection with the Fairway Acquisition pursuant to Section 2.8 of this Agreement shall be automatic and shall not require
the consent of any Lender); (C) no waiver, consent, release, modification or amendment of or supplement to any Hedging Contract, fee letter between any Restricted Person or any Arranger or Agent, or any letter of credit application shall be
valid or effective against any party thereto without the consent of such party, and any such documents may be waived, consented to, released, modified or amended in accordance with the terms of such documents; and (D) in connection with any
proposed amendment, modification, waiver or termination (a “Proposed Change”) requiring the consent of all Lenders, if the consent of Required Lenders is obtained, but the consent of the other Lenders whose consent is required is
not obtained (any such Lender whose consent is not obtained being referred to as a “Non-Consenting Lender”), then so long as the Agent is not a Non-Consenting Lender, at the Borrower’s request the Agent, or one or more Eligible
Transferees, shall have the right (but not the obligation and in each case with the Agent’s consent and in the Agent’s sole discretion) to purchase from such Non-Consenting Lenders, and such Non-Consenting Lenders agree that they shall,
upon the Agent’s request, sell and assign to the Agent or such Person, all of the Loans, Notes and Commitments of such Non-Consenting Lenders in accordance with Section 3.8, such purchase and sale to be consummated pursuant to an

  
 85 

 
executed Assignment and Acceptance. Notwithstanding anything to the contrary herein, no Defaulting Lender shall have any right to approve or disapprove any amendment, waiver or consent hereunder,
except that the Commitment of such Lender may not be increased or extended without the consent of such Lender. 
 (b) Acknowledgments and Admissions. Borrower hereby represents, warrants, acknowledges and admits that (i) it has been advised by counsel in the negotiation, execution and delivery of the Loan
Documents to which it is a party, (ii) it has made an independent decision to enter into this Agreement and the other Loan Documents to which it is a party, without reliance on any representation, warranty, covenant or undertaking by Agent or
any Lender Party, whether written, oral or implicit, other than as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iii) there are no representations, warranties, covenants, undertakings or
agreements by any Lender Party as to the Loan Documents except as expressly set out in this Agreement or in another Loan Document delivered on or after the date hereof, (iv) no Lender Party has any fiduciary obligation toward Borrower with
respect to any Loan Document or the transactions contemplated thereby, (v) the relationship pursuant to the Loan Documents between Borrower and the other Restricted Persons, on one hand, and each Lender Party, on the other hand, is and shall be
solely that of debtor and creditor, respectively, (vi) no partnership or joint venture exists with respect to the Loan Documents between any Restricted Person and any Lender Party, (vii) Agent is not Borrower’s Agent, but Agent for
Lenders in the capacity described in the second sentence of Section 9.1, (viii) should an Event of Default or Default occur or exist, each Lender Party will determine in its sole discretion and for its own reasons what remedies and actions
it will or will not exercise or take at that time, (ix) without limiting any of the foregoing, Borrower is not relying upon any representation or covenant by any Lender Party, or any representative thereof, and no such representation or
covenant has been made, that any Lender Party will, at the time of an Event of Default or Default, or at any other time, waive, negotiate, discuss, or take or refrain from taking any action permitted under the Loan Documents with respect to any such
Event of Default or Default or any other provision of the Loan Documents, and (x) all Lender Parties have relied upon the truthfulness of the acknowledgments in this section in deciding to execute and deliver this Agreement and to become
obligated hereunder. 
 (c) Representation by Lenders. Each Lender hereby represents that
it will acquire its Note for its own account in the ordinary course of its commercial lending business; however, the disposition of such Lender’s property shall at all times be and remain within its control and, in particular and without
limitation, such Lender may sell or otherwise transfer its Notes, Loans, Letters of Credit and Commitments, any participation interest or other interest in its Notes, Loans, Letters of Credit or Commitments, or any of its other rights and
obligations under the Loan Documents. 
 (d) Joint Acknowledgment. THIS WRITTEN AGREEMENT
AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. 

  
 86 

 THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

 Section 10.2. Survival of Agreements; Cumulative Nature. All of Restricted Persons’ various
representations, warranties, covenants and agreements in the Loan Documents shall survive the execution and delivery of this Agreement and the other Loan Documents and the performance hereof and thereof, including the making or granting of the Loans
and the delivery of the Notes and the other Loan Documents, and shall further survive until all of the Obligations are paid in full to each Lender Party and all of Lender Parties’ obligations to Borrower are terminated. All statements and
agreements contained in any certificate or other instrument delivered by any Restricted Person to any Lender Party under any Loan Document shall be deemed representations and warranties by Borrower or agreements and covenants of Borrower under this
Agreement. The representations, warranties, indemnities, and covenants made by Restricted Persons in the Loan Documents, and the rights, powers, and privileges granted to Lender Parties in the Loan Documents, are cumulative, and, except for
expressly specified waivers and consents, no Loan Document shall be construed in the context of another to diminish, nullify, or otherwise reduce the benefit to any Lender Party of any such representation, warranty, indemnity, covenant, right, power
or privilege. In particular and without limitation, no exception set out in this Agreement to any representation, warranty, indemnity, or covenant herein contained shall apply to any similar representation, warranty, indemnity, or covenant contained
in any other Loan Document, and each such similar representation, warranty, indemnity, or covenant shall be subject only to those exceptions which are expressly made applicable to it by the terms of the various Loan Documents. 

Section 10.3. Notices. All notices, requests, consents, demands and other communications required or
permitted under any Loan Document shall be in writing, unless otherwise specifically provided in such Loan Document (provided that Agent may give telephonic notices to the other Lender Parties), and shall be deemed sufficiently given or furnished if
delivered by personal delivery, by telecopy, by delivery service with proof of delivery, or by registered or certified United States mail, postage prepaid, to Borrower and Restricted Persons at the address of Borrower specified on the signature
pages hereto and to each Lender Party at its address specified in the Lenders Schedule as its lending offices for ABR Loans (unless changed by similar notice in writing given by the particular Person whose address is to be changed). Any such notice
or communication shall be deemed to have been given (a) in the case of personal delivery or delivery service, as of the date of first attempted delivery during normal business hours at the address provided herein, (b) in the case of
telecopy, upon receipt, or (c) in the case of registered or certified United States mail, three days after deposit in the mail; provided, however, that no Borrowing Notice shall become effective until actually received by Agent. 

Section 10.4. Payment of Expenses; Indemnity. 

(a) Payment of Expenses. Whether or not the transactions contemplated by this Agreement are
consummated, Borrower will promptly (and in any event, within 30 days after any invoice or other statement or notice) pay: (i) all transfer, stamp, mortgage, documentary or other similar taxes, assessments or charges levied by any governmental
or revenue authority in respect of this Agreement or any of the other Loan Documents or 

  
 87 

 
any other document referred to herein or therein, (ii) all reasonable costs and expenses incurred by or on behalf of Agent (including attorneys’ fees, consultants’ fees and
engineering fees, travel costs and miscellaneous expenses) in connection with (l)the negotiation, preparation, execution and delivery of the Loan Documents, and any and all consents, waivers, amendments or modifications or other documents or
instruments relating thereto, (2) the filing, recording, refiling and re-recording of any Loan Documents and any other documents or instruments or further assurances required to be filed or recorded or refiled or re-recorded by the terms of any
Loan Document, (3) the borrowings hereunder and other action reasonably required in the course of administration hereof, (4) monitoring or confirming (or preparation or negotiation of any document related to) Borrower’s compliance
with any covenants or conditions contained in this Agreement or in any Loan Document, and (iii) all reasonable costs and expenses incurred by or on behalf of any Lender Party (including reasonable attorneys’ fees, consultants’ fees
and accounting fees) in connection with the defense or enforcement of any of the Loan Documents (including this section) or the defense of any Lender Party’s exercise of its rights thereunder. In addition to the foregoing, until all Obligations
have been paid in full, Borrower will also pay or reimburse Agent for all reasonable out-of-pocket costs and expenses of Agent or its agents or employees in connection with the continuing administration of the Loans and the related due diligence of
Agent, including travel and miscellaneous expenses and fees and expenses of Agent’s outside counsel, reserve engineers and consultants engaged in connection with the Loan Documents. 

(b) Indemnity. Borrower agrees to indemnify each Lender Party, upon demand, from and against any
and all liabilities, obligations, claims, losses, damages, penalties, fines, actions, judgments, suits, settlements, costs, expenses or disbursements (including reasonable fees of attorneys, accountants, experts and advisors) of any kind or nature
whatsoever (in this section collectively called “liabilities and costs”) which to any extent (in whole or in part) may be imposed on, incurred by, or asserted against such Lender Party by the Borrower or any Restricted Person or by any
third party growing out of, resulting from or in any other way associated with any of the Collateral, the Loan Documents and the transactions and events (including the enforcement or defense thereof) at any time associated therewith or contemplated
therein (including any Environmental Claims or violation or noncompliance with any Environmental Laws by any Restricted Person or any liabilities or duties of any Restricted Person or any Lender Party with respect to the presence or Release of
Hazardous Materials found in or released into the environment). For the avoidance of doubt, any indemnification relating to Taxes shall be covered exclusively by Section 3.6 and shall not be covered by this Section 10.4. 

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR
IN PART, UNDER ANY CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY LENDER PARTY, 

  
 88 

 provided only that no Lender Party shall be entitled under this section to receive
indemnification for that portion, if any, of any liabilities and costs which is proximately caused by its own individual gross negligence or willful misconduct, as determined in a final judgment. If any Person (including Borrower or any of its
Affiliates) ever alleges such gross negligence or willful misconduct by any Lender Party, the indemnification provided for in this section shall nonetheless be paid upon demand, subject to later adjustment or reimbursement, until such time as a
court of competent jurisdiction enters a final judgment as to the extent and effect of the alleged gross negligence or willful misconduct. As used in this section the term “Lender Parties” shall refer not only to the Persons designated as
such in Section 1.1 but also to each director, officer, agent, attorney, employee, representative and Affiliate of such Persons. 
 Section 10.5. Joint and Several Liability; Parties in Interest. All Obligations which are incurred by two or more Restricted Persons shall be their joint and several obligations and
liabilities. All grants, covenants and agreements contained in the Loan Documents shall bind and inure to the benefit of the parties thereto and their respective successors and assigns; provided, however, that no Restricted Person may assign or
transfer any of its rights or delegate any of its duties or obligations under any Loan Document without the prior consent of Required Lenders. Except as otherwise provided in this Agreement, neither Borrower nor any Affiliates of Borrower shall
directly or indirectly purchase or otherwise retire any Obligations owed to any Lender nor will any Lender accept any offer to do so, unless each Lender shall have received substantially the same offer with respect to the same Aggregate Percentage
Share of the Obligations owed to it. If Borrower or any Affiliate of Borrower at any time purchases some but less than all of the Obligations owed to all Lender Parties, such purchaser shall not be entitled to any rights of any Lender Party under
the Loan Documents unless and until Borrower or its Affiliates have purchased all of the Obligations. 

Section 10.6. Assignments. 

(a) Participations 

(A) Any Lender may sell a participation interest in its commitments hereunder or any of its rights under
its Loans or under the Loan Documents to any Person, provided that the agreement between such Lender and such participant must at all times provide: (i) that such participation exists only as a result of the agreement between such participant
and such Lender and that such transfer does not give such participant any right to vote as a Lender or any other direct claims or rights against any Person other than such Lender, (ii) that such participant is not entitled to payment from any
Restricted Person under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6 of amounts in excess of those payable to such Lender under such sections (determined without regard to the sale of such participation), and (iii) unless such participant is an
Affiliate of such Lender, that such participant shall not be entitled to require such Lender to take any action under any Loan Document or to obtain the consent of such participant prior to taking any action under any Loan Document, except for
actions which would require the consent of all Lenders under the next-to-last sentence of subsection (a) of Section 10.1. No Lender selling such a participation shall, as between the other parties hereto and such Lender, be relieved of any
of its obligations hereunder as a result of the sale of such participation. Each Lender which sells any such participation to any Person (other than an Affiliate of such Lender) shall give prompt notice thereof to Agent and Borrower. 

  
 89 

 (B) Each Lender that sells a participation shall, acting
solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the 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 to any Person (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) 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.l03-l(c) of the United States Treasury Regulations. Unless otherwise required by the Internal Revenue Service, any disclosure required by the
foregoing sentence shall be made by the relevant Lender directly and solely to the Internal Revenue Service. 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. 

(b) Except for sales of participations under the immediately preceding subsection (a), no Lender shall
make any assignment or transfer of any kind of its commitments or any of its rights under its Loans or under the Loan Documents, except for assignments to an Eligible Transferee, and then only if such assignment is made in accordance with the
following requirements: 
 (i) Unless otherwise consented to in writing by Agent and so long as
no Default or Event of Default is continuing by Borrower, which consents in each case shall be made in the sole and absolute discretion of Agent and Borrower, as applicable, in the case of an assignment of Revolving Loans and Revolving Loan
Commitments, (1) each such assignment shall apply to all Revolving Loans owing to the assignor and to the unused portion of the assignor Revolving Loan Commitments and (2) immediately after giving effect to such assignment, the
assignor’s Revolving Loan Commitment shall not be less than $5,000,000 and the assignee’s Revolving Loan Commitment shall equal or exceed $5,000,000 (unless such assignor is assigning all of its Revolving Loan Commitments and Revolving
Loans or unless such assignment is to an Affiliate of such assignor or an Approved Fund administered or managed by such assignor or an Affiliate of such assignor). 

(ii) The parties to each such assignment shall execute and deliver to Agent, for its acceptance and
recording in the Register, an Assignment and Acceptance, appropriately completed, together with the Note subject to such assignment and a processing fee payable to Agent of $3,500. Upon such execution, delivery, and payment and upon the satisfaction
of the conditions set 

  
 90 

 
out in such Assignment and Acceptance, then (A) Borrower shall, if requested by the assignor and/or assignee, issue new Revolving Loan Notes, to such assignor and assignee in exchange for
the return of the old Notes to Borrower, and (B) as of the “Effective Date” specified in such Assignment and Acceptance the assignee thereunder shall be a party hereto and a Lender hereunder and Agent shall thereafter deliver or make
available to Borrower and each Lender one or more schedules showing the revised Percentage Shares of all other Lenders. 
 (iii) Each assignee Lender shall (to the extent it has not already done so) provide Agent and Borrower with the documentation referred to in Section 3.6(e). 

(c) Nothing contained in this section shall prevent or prohibit any Lender from assigning or pledging all
or any portion of its Loans and Note to any Federal Reserve Bank as collateral security pursuant to Regulation A of the Board of Governors and any Operating Circular issued by such Federal Reserve Bank or to any central bank having jurisdiction over
such Lender or to one of its Affiliates or as otherwise required by applicable Law; provided that no such assignment or pledge shall relieve such Lender from its obligations hereunder. 

(d) By executing and delivering an Assignment and Acceptance, each assignee Lender thereunder will be
confirming to and agreeing with Borrower, Agents and each other Lender hereunder that such assignee understands and agrees to the terms hereof, including Article IX hereof. 

Section 10.7. Confidentiality. Each Lender Party agrees that it will follow its customary procedures to keep
confidential any proprietary information given to it by any Restricted Person, provided, however, that this restriction shall not apply to information which (a) has at the time in question entered the public domain, (b) is required to be
disclosed by Law (whether valid or invalid) of any Tribunal or is disclosed pursuant to Section 10.18, (c) is disclosed to any Lender Party’s Affiliates, auditors, attorneys, agents or to any credit insurance provider relating to the
Borrower and its obligations, (d) is furnished to any other Lender Party or to any purchaser or prospective purchaser of participations or other interests in any Loan or Loan Document or to any direct, indirect, actual or prospective
counterparty (and its advisor) to any swap, derivative or securitization transaction related to the obligations under this Agreement (provided each such purchaser, prospective purchaser, counterparty or prospective counterparty first agrees to hold
such information in confidence on the terms provided in this section), (e) is furnished to S&P or Moody’s or any similar organization or any nationally recognized rating agency in connection with ratings issued with respect to such
Lender Party or with respect to any Restricted Person, or (f) is disclosed in the course of enforcing its rights and remedies during the existence of an Event of Default; provided, however, that this obligation of confidence shall
not apply to, and each of Agent and the other Lender Parties (and each Person employed or retained by them who are or are expected to become engaged in evaluating, approving, structuring or administering the Loans) may disclose to any Tribunal,
without limitation of any kind, the tax treatment and tax structure of the transactions contemplated by this Agreement and the other Loan Documents, and all materials of any kind (including opinions or other tax analyses) related thereto that are or
have been provided to the Agent or such Lender Party relating to such tax treatment or tax structure. 

  
 91 

 Section 10.8. Governing Law; Submission to Process. Except to
the extent that the law of another jurisdiction is expressly elected in a Loan Document, the Loan Documents shall be deemed contracts and instruments made under and governed by the laws of the State of New York (including for such purposes Sections
5-1401 AND 5-1402 of the General Obligations Law of the State of New York). In any legal proceeding relating to the Loan Documents or the Obligations, each of the parties hereto hereby irrevocably submits itself to the exclusive jurisdiction of the
state and federal courts sitting in Harris County, Texas and agrees and consents that service of process may be made upon it in any legal proceeding relating to the Loan Documents or the Obligations by any means allowed under applicable Law.

 Section 10.9. Limitation on Interest. Lender Parties, Restricted Persons and any other parties to
the Loan Documents intend to contract in strict compliance with applicable usury Law from time to time in effect. In furtherance thereof such Persons stipulate and agree that none of the terms and provisions contained in the Loan Documents shall
ever be construed to create a contract to pay, for the use, forbearance or detention of money, interest in excess of the maximum amount of interest permitted to be charged by applicable Law from time to time in effect. Neither any Restricted Person
nor any present or future guarantors, endorsers, or other Persons hereafter becoming liable for payment of any Obligation shall ever be liable for unearned interest thereon or shall ever be required to pay interest thereon in excess of the maximum
amount that may be lawfully charged under applicable Law from time to time in effect, and the provisions of this section shall control over all other provisions of the Loan Documents which may be in conflict or apparent conflict herewith. Lender
Parties expressly disavow any intention to charge or collect excessive unearned interest or finance charges in the event the maturity of any Obligation is accelerated. If (a) the maturity of any Obligation is accelerated for any reason,
(b) any Obligation is prepaid and as a result any amounts held to constitute interest are determined to be in excess of the legal maximum, or (c) any Lender or any other holder of any or all of the Obligations shall otherwise collect
moneys which are determined to constitute interest which would otherwise increase the interest on any or all of the Obligations to an amount in excess of that permitted to be charged by applicable Law then in effect, then all sums determined to
constitute interest in excess of such legal limit shall, without penalty, be promptly applied to reduce the then outstanding principal of the related Obligations or, at such Lender’s or holder’s option, promptly returned to US Borrower or
the other payor thereof upon such determination. In determining whether or not the interest paid or payable, under any specific circumstance, exceeds the maximum amount permitted under applicable Law, Lender Parties and Restricted Persons (and any
other payors thereof) shall to the greatest extent permitted under applicable Law, characterize any non-principal payment as an expense, fee or premium rather than as interest, exclude voluntary prepayments and the effects thereof, and amortize,
prorate, allocate, and spread the total amount of interest throughout the entire contemplated term of the instruments evidencing the Obligations in accordance with the amounts outstanding from time to time thereunder and the maximum legal rate of
interest from time to time in effect under applicable Law in order to lawfully charge the maximum amount of interest permitted under applicable Law. As used in this section the term “applicable Law” means the Laws of the State of New York
or the Laws of the United States of America, whichever Laws allow the greater interest, as such Laws now exist or may be changed or amended or come into effect in the future. 

  
 92 

 Section 10.10. Termination; Limited Survival. In its sole and
absolute discretion Borrower may at any time that no Obligations are owing elect in a written notice delivered to Agent to terminate this Agreement. Upon receipt by Agent of such a notice, if no Obligations are then owing this Agreement and all
other Loan Documents shall thereupon be terminated and the parties thereto released from all prospective obligations thereunder. Notwithstanding the foregoing or anything herein to the contrary, any waivers or admissions made by any Restricted
Person in any Loan Document, any Obligations under any of Sections 3.2, 3.3, 3.4, 3.5 or 3.6, and any obligations which any Person may have to indemnify or compensate any Lender Party shall survive any termination of this Agreement or any other Loan
Document. At the request and expense of Borrower, Agent shall prepare and execute all necessary instruments to reflect and effect such termination of the Loan Documents. Agent is hereby authorized to execute all such instruments on behalf of all
Lenders, without the joinder of or further action by any Lender. 
 Section 10.11. Severability. If
any term or provision of any Loan Document shall be determined to be illegal or unenforceable all other terms and provisions of the Loan Documents shall nevertheless remain effective and shall be enforced to the fullest extent permitted by
applicable Law. 
 Section 10.12. Counterparts. This Agreement may be separately executed in any
number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to constitute one and the same Agreement. 

Section 10.13. Waiver of Jury Trial, Punitive Damages, etc. Borrower and each Lender Party hereby knowingly,
voluntarily, intentionally, and irrevocably (a) waives, to the maximum extent not prohibited by Law, any right it may have to a trial by jury in respect of any litigation based hereon, or directly or indirectly at any time arising out of, under
or in connection with the Loan Documents or any transaction contemplated thereby or associated therewith, before or after maturity; (b) waives, to the maximum extent not prohibited by Law, any right it may have to claim or recover in any such
litigation any “Special Damages”, as defined below, (c) certifies that no party hereto nor any representative or agent or counsel for any party hereto has represented, expressly or otherwise, or implied that such party would not, in
the event of litigation, seek to enforce the foregoing waivers, and (d) acknowledges that it has been induced to enter into this Agreement, the other Loan Documents and the transactions contemplated hereby and thereby by, among other things,
the mutual waivers and certifications contained in this section. As used in this section, “Special Damages” includes all special, consequential, exemplary, or punitive damages (regardless of how named), but does not include any payments or
funds which any party hereto has expressly promised to pay or deliver to any other party hereto. 

Section 10.14. Release of Collateral; Collateral Matters; Hedging. Agent and each Lender Party hereby agree
that so long as no Event of Default shall have occurred and be continuing, Agent shall release from the Security Documents, upon written request by Borrower and at Borrower’s expense, interests in oil and gas properties sold or otherwise
transferred by any Restricted Person in compliance with Section 7.5, upon receipt of the indefeasible 

  
 93 

 
prepayment of the Loans and Letter of Credit Outstandings required in connection with such sale, if any. The benefit of the Security Documents and the provisions of this Agreement and the other
Loan Documents relating to the Collateral shall also extend to and be available on a pro rata basis to each Lender and such Lender’s Affiliates in respect of any obligations under a Hedging Contract with any Restricted Person, but only so long
as such Lender remains a party to this Agreement and this Agreement remains in effect. No Lender or Affiliate of a Lender shall have any voting or consent right under any Loan Document as a result of the existence of obligations owed to it under a
Hedging Contract. 
 Section 10.15. Amendment and Restatement. On the Closing Date, this Agreement
shall be deemed to restate and amend the Existing Credit Agreement in its entirety, whereupon all of the terms and provisions hereof shall supersede the terms and conditions thereof. The parties hereto further agree that, on the Closing Date, this
Agreement and the Notes shall serve to extend, renew and continue, but not to extinguish or novate, the Existing Notes and the corresponding loans and to amend, restate and supersede, but not to extinguish or cause to be novated the Indebtedness
under, the Existing Credit Agreement. Borrower hereby agrees that, on the Closing Date, (a) the Loans outstanding under the Existing Credit Agreement and all accrued and unpaid interest thereon, and (b) all accrued and unpaid fees under
the Existing Credit Agreement shall be deemed to be outstanding under and payable by this Agreement; provided that changes in the Percentage Shares, interest rates, or fee rates shall not change the amounts then accrued and owing to each Lender
Party under the Existing Credit Agreement immediately prior to the Closing Date. 
 Section 10.16. Other
Agents. None of the Persons identified in this Agreement as the “Arrangers” or “Co-Bookrunners” or the “Syndication Agent” or the “Co-Documentation Agents” shall have any right, power, obligation,
liability, responsibility or duty under this Agreement or any other Loan Document other than (a) except in the case of the Arrangers, those applicable to all Lenders as such or (b) as expressly provided for herein or therein. Without
limiting the foregoing, none of the Other Agents shall have or be deemed to have any fiduciary relationship with any Restricted Person or any Lender. Each of the Lenders and Borrower, on behalf of itself and the other Restricted Persons,
acknowledges that it has not relied, and will not rely, on any of the Other Agents in deciding to enter into this Agreement or in taking or not taking any action hereunder or under the Loan Documents. 

Section 10.17. USA Patriot Act Notice. The Agent 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 “Patriot Act”), it is required to obtain, verify and record information that identifies the Borrower and its partners,
which includes the names and addresses of the Borrower and its partners and other information that will allow the Agent to identify the Borrower and its Subsidiaries and partners in accordance with the Patriot Act. This notice is given in accordance
with the requirements of the Patriot Act and is effective as to Agent and each Lender Party. 

Section 10.18. Posting of Approved Electronic Communications. (a) In addition to providing the Agent
with all originals or copies of all Communications (as defined below) in the manner specified by Section 10.3, Borrower hereby also agrees, unless directed otherwise by the Agent or unless the electronic mail address referred to below has not
been provided by the Agent to Borrower, that it will, or will cause its Subsidiaries to, provide to the Agent all information, 

  
 94 

 
documents and other materials that it is obligated to furnish to the Agent or to the Lender Parties pursuant to the Loan Documents, including all notices, requests, financial statements,
financial and other reports, certificates and other information materials (all such communications being referred to herein collectively as “Communications”), by transmitting the Communications in an electronic/soft medium that is
properly identified in a format acceptable to the Agent to an electronic mail address as directed by the Agent. 

(b) Borrower further agrees that (i) the Agent may make the Communications available to the Lender Parties by
posting the Communications on Intralinks or a substantially similar electronic transmission system (the “Platform”) and (ii) certain of the Lenders may be “public-side” Lenders (i.e., Lenders that do not
wish to receive material non-public information with respect to the Borrower or its securities) (each, a “Public Lender”). Borrower hereby agrees that (A) all Communications that are to be made available to Public Lenders shall
be clearly and conspicuously marked “PUBLIC” which, at a minimum, shall mean that the word “PUBLIC” shall appear prominently on the first page thereof; (B) by marking Communications “PUBLIC,” the Borrower shall be
deemed to have authorized the Agent and each Lender Party to treat such Communications as either publicly available information or not material information (although it may be sensitive and proprietary) with respect to the Restricted Persons or
their securities for purposes of United States Federal and state securities laws; (C) all Communications marked “PUBLIC” are permitted to be made available through a portion of the Platform designated “Public Investor” or
other similar designation; and (D) the Agent shall be entitled to treat any Communications that are not marked “PUBLIC” as being suitable only for posting on a portion of the Platform not designated “Public Investor” or
otherwise not designated as public. 
 (c) THE PLATFORM IS PROVIDED “AS IS” AND “AS
AVAILABLE”. THE LENDER PARTIES DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF THE COMMUNICATIONS OR THE ADEQUACY OF THE PLATFORM AND EXPRESSLY DISCLAIM LIABILITY FOR ERRORS OR OMISSIONS IN THE COMMUNICATIONS. NO WARRANTY OF ANY KIND, EXPRESS,
IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS IS MADE BY THE LENDER PARTIES IN CONNECTION WITH THE
COMMUNICATIONS OR THE PLATFORM. IN NO EVENT SHALL THE LENDER PARTIES HAVE ANY LIABILITY TO ANY RESTRICTED PERSON, ANY LENDER OR ANY OTHER PERSON FOR DAMAGES OF ANY KIND, WHETHER OR NOT BASED ON STRICT LIABILITY AND INCLUDING DIRECT OR INDIRECT,
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES, LOSSES OR EXPENSES (WHETHER IN TORT, CONTRACT OR OTHERWISE) ARISING OUT OF ANY RESTRICTED PERSON’S OR THE AGENT’S TRANSMISSION OF COMMUNICATIONS THROUGH THE INTERNET, EXCEPT TO THE EXTENT THE
LIABILITY OF ANY LENDER PARTY IS FOUND IN A FINAL RULING BY A COURT OF COMPETENT JURISDICTION TO HAVE RESULTED PRIMARILY FROM SUCH LENDER PARTY’S GROSS NEGLIGENCE OR WILLFUL MISCONDUCT. 

(d) The Agent agrees that the receipt of the Communications by the Agent at its e-mail address set forth above shall
constitute effective delivery of the Communications to the Agent for purposes of the Loan Documents. Each Lender Party agrees that receipt of notice to it 

  
 95 

 
(as provided in the next sentence) specifying that the Communications have been posted to the Platform shall constitute effective delivery of the Communications to such Lender Party for purposes
of the Loan Documents. Each Lender Party agrees to notify the Agent in writing (including by electronic communication) from time to time of such Lender Party’s e-mail address to which the foregoing notice may be sent by electronic transmission
and that the foregoing notice may be sent to such e-mail address. 
 (e) Nothing herein shall prejudice the
right of the Agent or any Lender Party to give any notice or other communication pursuant to any Loan Document in any other manner specified in such Loan Document. 

Section 10.19. Assignment and Reallocation of Existing Loans, Etc. On the Closing Date, each of the lenders
under the Existing Credit Agreement (each, an “Existing Lender”) hereby sells, assigns, transfers and conveys to the Lenders hereto, and each of the Lenders hereto hereby purchases and accepts, so much of the aggregate commitments
under, and loans and participations in letters of credit outstanding under, the Existing Credit Agreement such that, immediately after giving effect to the effectiveness of this Agreement (including any increase of the commitments effectuated
hereby), the Percentage Share of each Lender to this Agreement, the Loans of each Lender, and the portion of the relevant Commitment of each Lender, shall be as set forth on Schedule 3 hereto (it being understood that if any letters of credit are
outstanding under the Existing Credit Agreement as of the Closing Date of this Agreement, then each of the Revolving Loan Lenders shall have purchased and accepted from the Existing Lenders, a participation in such outstanding letters of credit
based on its respective Revolving Loan Percentage Share). The foregoing assignments, transfers and conveyances are without recourse to any Existing Lender and without any warranties whatsoever by the Agent, the Issuers or any Existing Lender as to
title, enforceability, collectibility, documentation or freedom from liens or encumbrances, in whole or in part, other than that the warranty of any such Existing Lender that it has not previously sold, transferred, conveyed or encumbered such
interests. The Existing Lenders and the Lenders shall, if appropriate, make all appropriate adjustments in payments under the Existing Credit Agreement, the “Notes” and the other “Loan Documents” thereunder for periods prior to
the adjustment date among themselves.

 IN WITNESS WHEREOF, this Agreement is executed as of the date first written

 ITEM 5.6 

No Material Adverse Change regarding Financial Statements 

On April 25, 2011, we entered into a purchase and sale agreement with private sellers to acquire approximately
21,900 gross leasehold acres (21,500 net acres) in the West Texas Permian Basin for a purchase price of $366 million, subject to adjustments and an effective date of January 1, 2011. At January 1, 2011, the estimated proved reserves to be
acquired were approximately 27 million barrel equivalents (164 Bcfe) (using a 6 to 1 Mcf to barrel equivalency). The estimated reserves are over 91% oil and natural gas liquids. The current wells produce approximately 2,800 net barrel
equivalents per day. Since January 1, 2011, production has increased from approximately 1,900 net barrel equivalents. 
 Capital expenditures associated with planned development activities for these properties for the balance of 2011 are currently estimated between $35 million and $40 million. The closing, which is subject
to customary closing conditions and normal closing price adjustments, including effective date adjustments, is anticipated in the second quarter and will be funded from cash on hand and borrowings under our revolving loan facility.

 FOR VALUE RECEIVED, the undersigned, W&T Offshore, Inc. a Texas corporation (herein
called “Borrower”), hereby promises to pay to                      (herein called “Lender”), the principal sum of
                 Dollars ($            ), or, if greater or less, the aggregate unpaid
principal amount of the Revolving Loans made under this Revolving Loan Note by Lender to Borrower pursuant to the terms of the Credit Agreement (as hereinafter defined), together with interest on the unpaid principal balance thereof as hereinafter
set forth, both principal and interest payable as herein provided in lawful money of the United States of America to Agent’s account at a bank located in New York, New York as designated in writing to Borrower by Agent, as from time to time may
be designated by the holder of this Revolving Loan Note. 
 This Revolving Loan Note (a) is issued and
delivered under that certain Fourth Amended and Restated Credit Agreement of May 5, 2011, by and among Borrower, Toronto Dominion (Texas) LLC, as Agent, and the lenders (including Lender) and letter-of-credit issuing banks referred to therein

Credit Agreement. Reference is hereby made to the Credit Agreement for a description of certain rights, limitations of rights, obligations and duties of the parties hereto and for the meanings assigned to terms used and not defined herein and to the
Security Documents for a description of the nature and extent of the security thereby provided and the rights of the parties thereto. 
 The principal amount of this Revolving Loan Note, together with all interest accrued hereon, shall be due and payable in full on the Maturity Date. 

So long as no Event of Default has occurred and is continuing, all ABR Loans (exclusive of any past due principal or
interest) from time to time outstanding shall bear interest on each day outstanding at the Alternate Base Rate in effect on such day. If an Event of Default has occurred and is continuing, all ABR Loans (exclusive of any past due principal or
interest) from time to time outstanding shall bear interest on each day outstanding at the Default Rate in effect on such day. On each ABR Payment Date Borrower shall pay to the holder hereof all unpaid interest which has accrued on the ABR Loans to

at which interest is payable on this Revolving Loan Note is limited by the Highest Lawful Rate (by the foregoing subsection (a) or by reference to the Highest Lawful Rate in the definitions of Alternate Base Rate, Eurodollar Rate, and Default
Rate), this Revolving Loan Note shall bear interest at the Highest Lawful Rate and shall continue to bear interest at the Highest Lawful Rate until such time as the total amount of interest accrued hereon equals (but does not exceed) the total
amount of interest which would have accrued hereon had there been no Highest Lawful Rate applicable hereto. 

Notwithstanding the foregoing paragraph and all other provisions of this Revolving Loan Note, in no event shall the
interest payable hereon, whether before or after maturity, exceed the maximum amount of interest which, under applicable Law, may be contracted for, charged, or received on this Revolving Loan Note, and this Revolving Loan Note is expressly made
subject to the provisions of the Credit Agreement which more fully set out the limitations on how interest accrues hereon. 
 If this Revolving Loan Note is placed in the hands of an attorney for collection after default, or if all or any part of the indebtedness represented hereby is proved, established or collected in any
court or in any bankruptcy, receivership, debtor relief, probate or other court proceedings, Borrower and all endorsers, sureties and guarantors of this Revolving Loan Note jointly and severally agree to pay reasonable attorneys’ fees and

trustee or any holder hereof, whether before or after maturity.

AND DUTIES OF THE PARTIES HERETO SHALL BE GOVERNED BY THE LAWS OF THE STATE OF NEW YORK (INCLUDING FOR SUCH PURPOSES SECTIONS 5-1401 AND 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK), EXCEPT TO THE EXTENT THE SAME ARE GOVERNED BY

 EXHIBIT F 
 FORM OF 
 [AMENDED AND RESTATED] GUARANTY 

THIS [AMENDED AND RESTATED] GUARANTY (this “Guaranty”) is made as of
            , 20    , by [NAME OF SUBSIDIARY], a Delaware limited liability company (“Guarantor”), in favor of Toronto Dominion (Texas)
LLC, individually and as agent (in such capacity, together with any successor or assign thereto, “Agent”) and each of the other Lender Parties (as defined in the Credit Agreement). 

RECITALS: 
 1. W&T Offshore, Inc., a Nevada corporation and predecessor to W&T Offshore, Inc., a Texas corporation (the “Borrower”), the Lenders (or their predecessors-in-interest), the
Issuers (or their predecessors-in-interest) and Toronto Dominion (Texas) LLC have heretofore entered into that certain Amended and Restated Credit Agreement, dated as of February 24, 2000 (as so amended), as amended and restated by that certain
Second Amended and Restated Credit Agreement dated as of March 15, 2005, among the Borrower, the Lenders, the Issuers and the Agent, as further amended and restated by that certain Third Amended and Restated Credit Agreement, dated as of
May 26, 2006 (as amended and modified from time to time, the “Existing Credit Agreement”), pursuant to which the Lenders and Issuers agreed to make Loans to the Borrower or issue or participate in Letters of Credit on behalf of
the Borrower. 
 2. [Pursuant to the Existing Credit Agreement, the Guarantor has heretofore executed and
delivered that certain Guaranty dated as of April 30, 2010, in favor of Toronto Dominion (Texas) LLC, and each of the lender parties described therein (the “Existing Guaranty”).] 

3. The Existing Credit Agreement is being amended and restated contemporaneously herewith pursuant to that certain Fourth
Amended and Restated Credit Agreement dated as of April     , 2011 (as from time to time amended, supplemented, restated or otherwise modified, the “Credit Agreement”), by and among the Borrower, the
Agent, the Issuers and the Lender Parties. 
 4. It is a condition precedent to each Lender Party’s
obligation to advance funds pursuant to the Credit Agreement and to the Issuers’ obligations to issue Letters of Credit pursuant to the Credit Agreement, that Guarantor shall execute and deliver this Guaranty to Agent. 

5. [The Guarantor intends that the Existing Guaranty be amended and restated, and superseded, by this Guaranty.]

 6. Borrower owns directly, or indirectly through one or more subsidiaries, one hundred percent (100%) of
the membership interests of Guarantor. 

  

 7. Borrower, Guarantor, and the other direct and indirect subsidiaries of
Borrower are mutually dependent on each other in the conduct of their respective businesses under a holding company structure, with the credit needed from time to time by each often being provided by another or by means of financing obtained by one
such affiliate with the support of the others for their mutual benefit and the ability of each to obtain such financing being dependent on the successful operations of the others. 

8. The members of Guarantor have determined that Guarantor’s execution, delivery and performance of this Guaranty
may reasonably be expected to benefit Guarantor, directly or indirectly, and is in the best interests of Guarantor. 
 NOW, THEREFORE, in consideration of the premises, of the benefits which will inure to Guarantor from Lender Parties’ advances of funds and Issuers’ issuances of Letters of Credit, and of Ten
Dollars and other good and valuable consideration, the receipt and sufficiency of all of which are hereby acknowledged, and in order (i) to induce Lender Parties to extend such credit under the Credit Agreement, (ii) to induce Issuers to
issue such Letters of Credit pursuant to the Credit Agreement, and (iii) to induce the Lender Parties to enter into the above-referenced Credit Agreement, Guarantor hereby agrees with Agent, for the benefit of Agent and each Lender Party, as
follows: 
 AGREEMENTS 
 Section 1. Definitions. Reference is hereby made to the Credit Agreement for all purposes. All terms used in this Guaranty which are defined in the Credit Agreement and not otherwise defined
herein shall have the same meanings when used herein. All references herein to any Loan Document or other document or instrument refer to the same as from time to time amended, supplemented or restated. As used herein the following terms shall have
the following meanings: 
 “Agent” means the Person who, at the time in question, is the
“Agent” under the Credit Agreement. Whenever there is only one Lender under the Credit Agreement, “Agent” shall also refer to such Lender in such capacity as the only Lender. 

“Hedging Obligations” means (i) any and all present or future obligations of Borrower according to
the terms of any present or future interest or currency rate swap, rate cap, rate floor, rate collar, exchange transaction, forward rate agreement, or other exchange or rate protection agreements or any option with respect to any such transaction
now existing or hereafter entered into between Borrower or any of its Subsidiaries and any then current Lender (or any Affiliate of any then current Lender); and (ii) any and all present or future obligations of Borrower according to the terms
of any present or future swap agreements, cap, floor, collar, exchange transaction, forward agreement or other exchange or protection agreements relating to crude oil, natural gas or other hydrocarbons, or any option with respect to any such
transaction now existing or hereafter entered into between Borrower or any of its Subsidiaries and any then current Lender (or any Affiliate of any then current Lender). 

“Obligations” means collectively all of the indebtedness, obligations, and undertakings which are
guaranteed by Guarantor and described in subsections (a) and (b) of Section 2. 

  
 2 

 “Obligors” means Borrower, Guarantor and any other
endorsers, guarantors or obligors, primary or secondary, of any or all of the Obligations. 

“Security” means any rights, properties, or interests of Agent or any Lender Party, under the Loan
Documents or otherwise, which provide recourse or other benefits to Agent or any Lender Party in connection with the Obligations or the non-payment or non-performance thereof, including collateral (whether real or personal, tangible or intangible)
in which Agent or any Lender Party have rights under or pursuant to any Loan Documents, guaranties of the payment or performance of any Obligation, bonds, surety agreements, keep-well agreements, letters of credit, rights of subrogation, rights of
offset, and rights pursuant to which other claims are subordinated to the Obligations. 
 Section 2.
Guaranty. 
 (a) Guarantor hereby irrevocably, absolutely, and unconditionally guarantees to Agent and
each other Lender Party the prompt, complete, and full payment when due, and no matter how the same shall become due, of: 
 (i) the Loans (whether or not evidenced by Notes), including all principal, all interest thereon and all other sums payable thereunder; 

(ii) all other “Obligations” (as defined in the Credit Agreement), including without limitation,
all other sums payable under the other Loan Documents, whether for principal, interest, fees or otherwise; and 
 (iii) all Hedging Obligations. 
 Without limiting the generality of the foregoing,
Guarantor’s liability hereunder shall extend to and include all post-petition interest, expenses, and other duties and liabilities of Borrower described above in this subsection (a), or below in the following subsection (b), which would be owed
by Borrower but for the fact that they are unenforceable or not allowable due to the existence of a bankruptcy, reorganization, or similar proceeding involving Borrower. 

(b) Guarantor hereby irrevocably, absolutely, and unconditionally guarantees to Agent and each other Lender Party the
prompt, complete and full performance, when due, and no matter how the same shall become due, of all obligations and undertakings of Borrower to Agent or such Lender Party under, by reason of, or pursuant to any of the Loan Documents. 

(c) If Borrower shall for any reason fail to pay any Obligation, as and when such Obligation shall become due and
payable, whether at its stated maturity, as a result of the exercise of any power to accelerate, or otherwise, Guarantor will, forthwith upon demand by Agent, pay such Obligation in full to Agent for the benefit of Agent or the Lender Party to whom
such Obligation is owed. If Borrower shall for any reason fail to perform promptly any Obligation, Guarantor will, forthwith upon demand by Agent, cause such Obligation to be performed or, if specified by Agent, provide sufficient funds, in such
amount and manner as Agent shall in good faith determine, for the prompt, full and faithful performance of such Obligation by Agent or such other Person as Agent shall designate. 

  
 3 

 (d) If either Borrower or Guarantor fails to pay or perform any Obligation
as described in the immediately preceding subsections (a), (b), or (c), Guarantor will incur the additional obligation to pay to Agent, and Guarantor will forthwith upon demand by Agent pay to Agent, the amount of any and all expenses, including
fees and disbursements of Agent’s counsel and of any experts or agents retained by Agent, which Agent may incur as a result of such failure. 
 (e) The liability of Guarantor hereunder shall be limited to the maximum amount of liability that can be incurred by Guarantor without rendering this Guaranty voidable under applicable law relating to
fraudulent conveyances or fraudulent transfers, and not for any greater amount. 
 Section 3.
Unconditional Guaranty. 
 (a) No action which Agent or any Lender Party may take or omit to take in
connection with any of the Loan Documents, any of the Obligations (or any other indebtedness owing by Borrower to Agent or any Lender Party), or any Security, and no course of dealing of Agent or any Lender Party with any Obligor or any other
Person, shall release or diminish Guarantor’s obligations, liabilities, agreements or duties hereunder, affect this Guaranty in any way, or afford Guarantor any recourse against Agent or any Lender Party, regardless of whether any such action
or inaction may increase any risks to or liabilities of Agent or any Lender Party or any Obligor or increase any risk to or diminish any safeguard of any Security. Without limiting the foregoing, Guarantor hereby expressly agrees that Agent and any
Lender Party may, from time to time, without notice to or the consent of Guarantor, do any or all of the following: 
 (i) Amend, change or modify, in whole or in part, any one or more of the Loan Documents and give or refuse to give any waivers or other indulgences with respect thereto. 

(ii) Neglect, delay, fail, or refuse to take or prosecute any action for the collection or enforcement of
any of the Obligations, to foreclose or take or prosecute any action in connection with any Security Document or other Loan Document, to bring suit against any Obligor or any other Person, or to take any other action concerning the Obligations or
the Loan Documents. 
 (iii) Accelerate, change, rearrange, extend, or renew the time, rate,
terms, or manner for payment or performance of any one or more of the Obligations (whether for principal, interest, fees, expenses, indemnifications, affirmative or negative covenants, or otherwise). 

(iv) Compromise or settle any unpaid or unperformed Obligation or any other obligation or amount due or
owing, or claimed to be due or owing, under any one or more of the Loan Documents. 
 (v) Take,
exchange, amend, eliminate, surrender, release, or subordinate any or all Security for any or all of the Obligations, accept additional or substituted Security therefor, and perfect or fail to perfect Agent’s or any Lender Party’s rights
in any or all Security. 

  
 4 

 (vi) Discharge, release, substitute or add Obligors.

 (vii) Apply all monies received from Obligors or others, or from any Security for any of the
Obligations, as Agent or any Lender Party may determine to be in their best interest, without in any way being required to marshall Security or assets or to apply all or any part of such monies upon any particular Obligations. 

(b) No action or inaction of any Obligor or any other Person, and no change of law or circumstances, shall release or
diminish Guarantor’s obligations, liabilities, agreements, or duties hereunder, affect this Guaranty in any way, or afford Guarantor any recourse against Agent or any Lender Party. Without limiting the foregoing, the obligations, liabilities,
agreements, and duties of Guarantor under this Guaranty shall not be released, diminished, impaired, reduced, or affected by the occurrence of any or all of the following from time to time, even if occurring without notice to or without the consent
of Guarantor: 
 (i) Any voluntary or involuntary liquidation, dissolution, sale of all or
substantially all assets, marshalling of assets or liabilities, receivership, conservatorship, assignment for the benefit of creditors, insolvency, bankruptcy, reorganization, arrangement, or composition of any Obligor or any other proceedings
involving any Obligor or any of the assets of any Obligor under laws for the protection of debtors, or any discharge, impairment, modification, release, or limitation of the liability of, or stay of actions or lien enforcement proceedings against,
any Obligor, any properties of any Obligor, or the estate in bankruptcy of any Obligor in the course of or resulting from any such proceedings. 
 (ii) The failure by Agent or any Lender Party to file or enforce a claim in any proceeding described in the immediately preceding subsection (i) or to take any other action in any proceeding to which
any Obligor is a party. 
 (iii) The release by operation of law of any Obligor from any of the
Obligations or any other obligations to Agent or any Lender Party, or any reduction, limitation, impairment or termination of any Obligations of the Borrower or any other Obligor for any reason, including any claim of waiver, release, surrender,
alteration or compromise. 
 (iv) The invalidity, deficiency, illegality, or unenforceability of
any of the Obligations or the Loan Documents, in whole or in part, any bar by any statute of limitations or other law of recovery on any of the Obligations, or any defense or excuse for failure to perform on account of force majeure, act of God,
casualty, impossibility, impracticability, or other defense or excuse whatsoever. 
 (v) The
failure of any Obligor or any other Person to sign any guaranty or other instrument or agreement within the contemplation of any Obligor, Agent or any Lender Party. 

  
 5 

 (vi) The fact that Guarantor may have incurred directly part
of the Obligations or is otherwise primarily liable therefor. 
 (vii) Without limiting any of
the foregoing, any fact or event (whether or not similar to any of the foregoing) which in the absence of this provision would or might constitute or afford a legal or equitable discharge or release of or defense to a guarantor or surety other than
the actual payment and performance by Guarantor under this Guaranty. 
 (c) Agent and any Lender Party may
invoke the benefits of this Guaranty before pursuing any remedies against any Obligor or any other Person and before proceeding against any Security now or hereafter existing for the payment or performance of any of the Obligations. Agent and any
Lender Party may maintain an action against Guarantor on this Guaranty without joining any other Obligor therein and without bringing a separate action against any other Obligor. 

(d) If any payment to Agent or any Lender Party by any Obligor is held to constitute a preference or a voidable transfer
under applicable state or federal laws, or if for any other reason Agent or any Lender Party is required to refund such payment to the pay or thereof or to pay the amount thereof to any other Person, such payment to Agent or such Lender Party shall
not constitute a release of Guarantor from any liability hereunder, and Guarantor agrees to pay such amount to Agent or such Lender Party on demand and agrees and acknowledges that this Guaranty shall continue to be effective or shall be reinstated,
as the case may be, to the extent of any such payment or payments. Any transfer by subrogation which is made as contemplated in Section 6 prior to any such payment or payments shall (regardless of the terms of such transfer) be
automatically voided upon the making of any such payment or payments, and all rights so transferred shall thereupon revert to and be vested in Agent and such Lender Party. 

(e) This is a continuing guaranty and shall apply to and cover all Obligations and renewals and extensions thereof and
substitutions therefor from time to time. 
 Section 4. Waiver. Guarantor hereby waives, with
respect to the Obligations, this Guaranty, and the other Loan Documents: 
 (a) notice of the incurrence of any
Obligation by Borrower, and notice of any kind concerning the assets, liabilities, financial condition, creditworthiness, businesses, prospects, or other affairs of Borrower (it being understood and agreed that: (i) Guarantor shall take full
responsibility for informing itself of such matters, (ii) neither Agent nor any Lender Party shall have any responsibility of any kind to inform Guarantor of such matters, and (iii) Agent and each Lender Party are hereby authorized to
assume that Guarantor, by virtue of its relationships with Borrower which are independent of this Guaranty, has full and complete knowledge of such matters whenever any Lender Party extends credit to Borrower or take any other action which may
change or increase Guarantor’s liabilities or losses hereunder). 
 (b) notice that Agent, any Lender
Party, any Obligor, or any other Person has taken or omitted to take any action under any Loan Document or any other agreement or instrument relating thereto or relating to any Obligation, including, without limitation, in connection with any Lien
or security interest granted by Guarantor in favor of Agent or any Lender Party. 

  
 6 

 (c) notice of acceptance of this Guaranty. 

(d) demand, presentment for payment, and notice of demand, dishonor, nonpayment, or nonperformance. 

(e) notice of intention to accelerate, notice of acceleration, protest, notice of protest, notice of any exercise of
remedies (as described in the following Section 5 or otherwise), and all other notices of any kind whatsoever. 
 Section 5. Exercise of Remedies. Agent and each Lender Party shall have the right to enforce, from time to time, in any order and at Agent’s or such Lender Party’s sole discretion,
any rights, powers and remedies which Agent or such Lender Party may have under the Loan Documents or otherwise, including judicial foreclosure, the exercise of rights of power of sale, the taking of a deed or assignment in lieu of foreclosure, the
appointment of a receiver to collect rents, issues and profits, the exercise of remedies against personal property, or the enforcement of any assignment of leases, rentals, oil or gas production, or other properties or rights, whether real or
personal, tangible or intangible; and Guarantor shall be liable to Agent and each Lender Party hereunder for any deficiency resulting from the exercise by Agent or any Lender Party of any such right or remedy even though any rights which Guarantor
may have against Lender Party or others may be destroyed or diminished by exercise of any such right or remedy. No failure on the part of Agent or any Lender Party to exercise, and no delay in exercising, any right hereunder or under any other Loan
Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right preclude any other or further exercise thereof or the exercise of any other right. If, in the exercise of any of its rights and remedies, any Lender
Party shall forfeit any of its rights or remedies, including its right to enter a deficiency judgment against any Obligor or any other Person, whether because of any applicable laws pertaining to “election of remedies” or the like,
Guarantor hereby consents to such action by such Lender Party and waives any claim based upon such action, even if such action by such Lender Party shall result in a full or partial loss of any rights of subrogation that Guarantor might otherwise
have had but for such action by such Lender Party. Any election of remedies that results in the denial or impairment of the right of any Lender Party to seek a deficiency judgment against the Borrower shall not impair Guarantor’s obligation to
pay the full amount of the Obligations. The rights, powers and remedies of Agent and each Lender Party provided herein and in the other Loan Documents are cumulative and are in addition to, and not exclusive of, any other rights, powers or remedies
provided by law or in equity. The rights of Agent and each Lender Party hereunder are not conditional or contingent on any attempt by Agent or any Lender Party to exercise any of its rights under any other Loan Document against any Obligor or any
other Person. 
 Section 6. Limited Subrogation. Until one year and one day after the indefeasible
payment in full in cash of all Obligations, the expiration or termination of all Letters of Credit and the termination of all Commitments, Guarantor shall have no right to exercise any right of subrogation, reimbursement, indemnity, exoneration,
contribution or any other claim which it may now or hereafter have against or to any Obligor or any Security in connection with this 

  
 7 

 
Guaranty, and Guarantor hereby waives any rights to enforce any remedy which Guarantor may have against Borrower and any right to participate in any Security until such time. If any amount shall
be paid to Guarantor on account of any such subrogation or other rights, any such other remedy, or any Security at any time when all of the Obligations and all other expenses guaranteed pursuant hereto shall not have been indefeasibly paid in full
in cash, all Letters of Credit have not expired or terminated or all Commitments have not terminated, such amount shall be held in trust for the benefit of Agent, shall be segregated from the other funds of Guarantor and shall forthwith be paid over
to Agent to be held by Agent as collateral for, or then or at any time thereafter applied in whole or in part by Agent against, all or any portion of the Obligations, whether matured or unmatured, in such order as Agent shall elect. If Guarantor
shall make payment to Agent of all or any portion of the Obligations and if all of the Obligations shall be indefeasibly paid in full in cash, all Letters of Credit have expired or terminated and all Commitments have terminated, Agent will, at
Guarantor’s request and expense, execute and deliver to Guarantor (without recourse, representation or warranty) appropriate documents necessary to evidence the transfer by subrogation to Guarantor of an interest in the Obligations resulting
from such payment by Guarantor; provided that such transfer shall be subject to Section 3(d) above and that without the consent of Agent (which Agent may withhold in its discretion) Guarantor shall not have the right to be subrogated to
any claim or right against any Obligor which has become owned by Agent or any Lender Party, whose ownership has otherwise changed in the course of enforcement of the Loan Documents, or which Agent otherwise has released or wishes to release from its
Obligations. 
 Section 7. Successors and Assigns. Guarantor’s rights or obligations hereunder
may not be assigned or delegated, but this Guaranty and such obligations shall pass to and be fully binding upon the successors of Guarantor, as well as Guarantor. This Guaranty shall apply to and inure to the benefit of Agent and each Lender Party
and their successors or assigns, including, without limitation, any such Person permitted under the Credit Agreement. 
 Section 8. Subordination. Guarantor hereby subordinates and makes inferior to the Obligations any and all indebtedness now or at any time hereafter owed by Borrower to Guarantor. Guarantor
agrees that after the occurrence of any Default or Event of Default it will neither permit Borrower to repay such indebtedness or any part thereof nor accept payment from Borrower of such indebtedness or any part thereof without the prior written
consent of Agent. If Guarantor receives any such payment without the prior written consent of Agent, the amount so paid shall be held in trust for the benefit of each Lender Party, shall be segregated from the other funds of Guarantor, and shall
forthwith be paid over to Agent to be held by Agent as collateral for, or then or at any time thereafter applied in whole or in part by Agent against, all or any portions of the Obligations, whether matured or unmatured, in such order as Agent shall
elect. At the Agent’s request, Guarantor will promptly mark its books and records, and cause any Subsidiary of Guarantor to mark its books and records, so as to indicate that any and all indebtedness now or at any time hereafter owed by
Borrower to Guarantor is subordinated in accordance with the terms of this Guaranty, and will cause to be clearly inserted in any promissory note or other instrument which at any time evidences any such indebtedness a statement to the effect that
the payment thereof is subordinated in accordance with the terms of this Guaranty. Guarantor shall execute such further documents or instruments and take such further action as the Agent may reasonably from time to time request to carry out the
intent of 

  
 8 

 
this Guaranty. Guarantor hereby grants to each Lender Party a right of offset to secure the payment of the Obligations and Guarantor’s obligations and liabilities hereunder, which right of
offset shall be upon any and all monies, securities and other property (and the proceeds therefrom) of Guarantor now or hereafter held or received by or in transit to Agent or any Lender Party from or for the account of Guarantor, whether for
safekeeping, custody, pledge, transmission, collection or otherwise, and also upon any and all deposits (general or special), credits and claims of Guarantor at any time existing against Agent or any Lender Party. Upon the occurrence of any Default
or Event of Default, Agent and each Lender Party is hereby authorized at any time and from time to time, without notice to Guarantor, to offset, appropriate and apply any and all items hereinabove referred to against the Obligations and
Guarantor’s obligations and liabilities hereunder irrespective of whether or not Agent or such Lender Party shall have made any demand under this Guaranty and although such obligations and liabilities may be contingent or unmatured. Agent and
each Lender Party agrees promptly to notify Guarantor after any such offset and application made by Agent or such Lender Party, provided that the failure to give such notice shall not affect the validity of such offset and application. The rights of
Agent and each Lender Party under this Section 8 are in addition to, and shall not be limited by, any other rights and remedies (including other rights of offset) which Agent and any Lender Party may have. 

Section 9. Representations and Warranties. Guarantor hereby represents and warrants to Agent and each Lender

Parties shall have no obligation to investigate the financial condition or affairs of any Obligor for the benefit of Guarantor nor to advise Guarantor of any fact respecting, or any change in, the financial condition or affairs of the Borrower or
any other Obligor that might become known to Agent or any Lender Party at any time, whether or not such Person knows or believes or has reason to know or believe that any such fact or change is unknown to Guarantor, or might (or does) materially
increase the risk of Guarantor as guarantor, or might (or would) affect the willingness of Guarantor to continue as a guarantor of the Obligations.
