 Dear Mr. Stice: 
 Windsor Permian, LLC, a Delaware limited liability company
(the “Company”), hereby agrees to employ you and you hereby agree to accept such employment under the terms and conditions of this employment agreement (this “Agreement”), which amends and restates
your employment agreement originally effective as of April 18, 2011, as amended. 
 1.
Term of Employment. Except for earlier termination as provided in Section 9 below, your employment with the Company shall be for a term commencing as of April 18, 2011 (the “Effective Date”) and
terminating on the third (3rd) anniversary of the
Effective Date. The period of time between the Effective Date and the third (3rd) anniversary of the Effective Date shall be referred to herein as the “Term.” 
 2. Compensation. 
 (a) During the Term, you shall be compensated for
all services rendered by you under this Agreement at the rate of $300,000 per annum (the “Base Salary”). The Base Salary shall be payable in such manner as is consistent with the Company’s payroll practices for executive
employees and subject to the usual, required withholding. 
 (b) During the Term, you shall be eligible to receive an annual
bonus in accordance with the Company’s bonus policy to be established by the Manager of the Company if a limited liability company or Board of Directors of the Company if a corporation (the “Board”) from time to time
(the “Annual Bonus”). The Annual Bonus shall be determined by the Board based upon your achievement of performance goals as determined by the Board for each fiscal year of the Company. You shall be eligible to receive a
target Annual Bonus of $300,000 upon achievement of your performance goals. You shall receive a minimum Annual Bonus of $200,000 and be eligible to receive an Annual Bonus of up to $400,000 based upon your achievement of stretch goals as determined
by the Board. The Annual Bonus shall be paid within fifteen (15) business days after (i) completion and release of the audited financial statements for the applicable fiscal year or (ii) the close and approval by the Board of the
Company’s books for the applicable fiscal year if the Board determines that an audit is not required; provided, however, except as otherwise provided in Section 9(c), you must still be employed by the Company on the payment date to receive
the Annual Bonus. 

 (c) On the Effective Date, you were granted an option (the
“Purchase Option”) to acquire a one percent (1%) membership interest in the Company for the total amount of $3,600,000.00 (the “Purchase Option Exercise Price”). If the Company sells a portion of
its oil and gas properties before you exercise the Purchase Option, the exercise price will be reduced by an amount equal to one percent (1%) of the net proceeds from such sale(s) but only to the extent that such net proceeds have actually been
distributed to the holders of the Company’s membership interests prior to the Contribution (as defined in Section 2(d) below) or to the stockholders of Diamondback (as defined below) after the Contribution (as defined below) (the
“Reduction Amount”). However, in no event will the Reduction Amount exceed an amount that will cause the exercise price to be less than the fair market value of the membership interests subject to the Purchase Option on the
date the Reduction Amount becomes applicable. In order to exercise any vested portion of the Purchase Option, you must give the Board written notice of your desire to acquire a one percent (1%) membership interest in the Company, which notice
shall be given on or before the earlier of (i) the fifth (5th) anniversary date of the Effective Date; and (ii) the termination of your employment with the Company for any reason or no reason other than your death, Disability or No Cause Termination (each
as defined below) (the “Expiration Date”); provided, however, that your right to exercise the Purchase Option shall be suspended commencing on the date a registration statement relating to an IPO (as defined below) is filed
with the Securities and Exchange Commission and such suspension shall continue until the earliest of: (x) December 31, 2013, (y) the date the registration statement is withdrawn and (z) the date a definitive agreement for the
sale of the Company or all or substantially all of its assets is entered into (the “Exercise Suspension Period”). In the event your employment with the Company terminates on account of your death, Disability or No Cause
Termination, the Expiration Date will be the earlier of the fifth (5th) anniversary date of the Effective Date or the 90th day following your death, Disability or No Cause Termination; provided, however, if the period of time between your
death, Disability or No Cause Termination and the Expiration date at all times is subject to Exercise Suspension Period, the Expiration Date will be the earlier of the fifth (5th) anniversary date of the Effective Date or the 30th day following
the end of the Exercise Suspension Period. If you fail to notify the Board in writing on or before the Expiration Date, then the Purchase Option shall terminate and you shall have no further right to acquire a membership interest in the Company. In
the event such Expiration Date is due to provision 2(c)(ii) above and the Company does not complete the initial public offering within 365 days from the date of such initial filing, the Purchase Option shall then again be available to you subject to
the terms and conditions hereof. In the event the Purchase Option is exercised by you, the Company and you, within ten (10) days from the day the Purchase Option is exercised, shall enter into a definitive acquisition agreement containing
typical terms of a transaction of this type, which shall also provide for a closing within fifteen (15) days from the day the Purchase Option is exercised and a company agreement containing restrictions on transfer, drag-along rights, capital
calls, dilution and such other terms as the Company may require. The Purchase Option shall vest in four (4) equal amounts commencing on the anniversary date of the Effective Date following such grant and each of the next following three
(3) anniversary dates of the Effective Date; provided, that if your employment terminates for any reason other than your death, Disability or No Cause Termination, the Purchase Option shall cease vesting as of the date of such
termination, and any unvested portion of the Company Option shall become void. In the event more than fifty percent (50%) of the membership interests or stock in the Company is owned by one or more third parties other than a Wexford Party
(defined below), any employee 

  
 2 

 benefit plan sponsored or maintained by a Wexford Party, any employee or group of persons including an
employee of a Wexford Party or an underwriter temporarily holding securities pursuant to an offering of securities and there is either (a) a material diminution in your position, duties, or authority or (b) your required relocation by the
Company to a location that is outside a 50-mile radius of Midland, Texas (an “Option Event”) or (ii) your death, Disability or No Cause Termination, then the Purchase Option shall vest immediately. Notwithstanding
anything to the contrary herein, if you exercise all or part of the Purchase Option under this Section 2(c), you will not be eligible for the Diamondback Option defined below. 

(d) It is currently contemplated that the Company will participate in an initial public offering (the “IPO”). The
IPO will be accomplished through the sale of common stock of a new Delaware corporation formed for that purpose (“Diamondback”), and an affiliate of the Company, pursuant to a registration statement filed with and declared
effective by the United States Securities and Exchange Commission. Prior to the completion of the IPO, all of the membership interests in the Company will be contributed to Diamondback in exchange for common stock of Diamondback (the
“Contribution”) and the Company will become a wholly-owned subsidiary of Diamondback. If the Contribution occurs, your Company Option to acquire membership interests of the Company will be canceled and your rights to acquire
membership interests in the Company and all your rights under the Company Option will terminate. If you continue to be employed at the time of the Contribution, you will be entitled to receive the following: (i) a cash bonus in the amount of
$1,000,000.00 (the “Transaction Bonus”), less applicable tax withholdings, of which two-thirds will be payable at the time of the IPO and one-third will be payable upon the first anniversary of the closing of the IPO if you
are still employed by the Company or if you were terminated by the Company prior to that date other than for “Cause” as defined in Section 9(b); (ii) the grant of Restricted Stock Units (the “RSU Award”)
in an amount equal to $1,000,000.00 divided by the initial price per share of the common stock to the public in the IPO (the “IPO Price”), rounded up or down to the closest whole number of Restricted Stock Units, upon the
terms and subject to the conditions set forth in the Diamondback Energy, Inc. 2012 Equity Incentive Plan (the “Plan”) and the RSU award agreement granted under the Plan, including the vesting commencement date and vesting
schedule, including the Option Event and other vesting events, applicable to the Purchase Option (provided that the first settlement date on which vested shares will be transferred to you will not be earlier than the expiration of any lock-up
agreements entered into in connection with the IPO); and (iii) the grant of an option to purchase 300,000 shares of Diamondback common stock (the “Diamondback Option”) upon the terms and subject to the conditions set
forth in the Plan. The Diamondback Option will be granted effective as of the date of the Contribution, will have an exercise price equal to the fair market value of the Diamondback common stock on the grant date (which will be the IPO Price) and
will be exercisable in accordance with the vesting commencement date and vesting schedule, including the Option Event and other vesting events, applicable to the Purchase Option. In order to exercise any vested portion of the Diamondback Option, you
shall give the Board written notice of your desire to exercise the Diamondback Option on or before the Expiration Date in the manner specified in the Plan and the option agreement. Payment of the Transaction Bonus and delivery of the RSU Award and
the Diamondback Option are intended to occur promptly after the closing of the IPO, but in no event later than thirty (30) days after the closing of the IPO.

 (e) During the Term, you shall be paid a monthly vehicle allowance in the amount of $900.

 3. Duties. 
 (a) You shall serve as President and Chief Operating Officer of the Company, shall be subject to the general supervision and control of the Board and/or such other officers or individuals as it may
designate, and shall provide such services customarily expected of such office and as may be reasonably requested by the Board (or its designee) from time to time. Your principal office shall be located in Midland, Texas. 

(b) During the Term, you shall devote your full business time, energies and attention to the business and affairs of the Company, and its
subsidiaries (collectively, the “Windsor Group” or the “Windsor Companies” and each of them, individually, a “Windsor Company”), and you may not be engaged in any other business
activities; provided, however, that you may be permitted to engage in such charitable activities and other limited business activities as both do not interfere with the performance of your duties under this Agreement and are approved
in writing by the Board. 
 (c) You shall: (i) provide services hereunder to the best of your skills or ability and in an
efficient manner and devote such time and effort to the business and affairs of the Company as necessary or advisable to perform your duties hereunder; (ii) act in a manner which you in good faith believe is in the best interests of the
Company; (iii) implement any business plan adopted by the Company and then in effect; (iv) perform your duties hereunder, including without limitation any duties reasonably assigned to you by the Board, in good faith; (v) keep the
Company reasonably informed on all matters that are material to the Company; (vi) be subject to, and comply with, the Company’s and the Windsor Group’s rules, practices and policies applicable to executive employees as reflected in
the employee handbook, codes of conduct, compliance policies or otherwise, as may be amended from time to time; and (vii) cause the Company to comply with all applicable laws and regulations and monitor the development, maintenance, operation
and management of the business of the Company to ensure such development, maintenance, operation and management complies with all applicable laws. 
 4. Benefits. You shall be entitled to twenty-five (25) paid vacation days per annum. You also shall have the benefit of such life and medical insurance plans and other similar plans as
the Windsor Group may have or may establish from time to time for its executive employees generally, subject to satisfaction of applicable eligibility requirements. The foregoing, however, shall not be construed to require any Windsor Company to
establish any such plans or to prevent any Windsor Company from modifying or terminating any such plans, and no such action or failure thereof shall affect this Agreement. 
 5. Expenses. The Company shall reimburse you, in accordance with Company policy, for reasonable expenses incurred by you in the ordinary course in connection with the business of the
Windsor Group upon the presentation by you of appropriate substantiation for such expenses. All expenses or other reimbursements under this Agreement shall be made in accordance with the Company’s policies.

 6. Restrictive Covenants. 

(a) Subject to Section 6(b) below, from the date hereof until the later of the termination of your employment with, engagement as a
consultant of, or other affiliation with, any Windsor Company, and for a period ending on the later of six (6) months thereafter (such period, the “Restricted Period”), you shall not, nor shall any of your affiliates,
without the written consent of the Board, at any time or in any manner, either directly or indirectly, become associated with, render services to, invest in, represent, advise or otherwise participate as an officer, employee, director, stockholder,
partner, member, agent of or consultant for any business or organization that engages or participates in the Restricted Business; provided, however, that nothing herein shall prevent you from acquiring up to two percent (2%) of
the securities of any company listed on a national securities exchange or quoted on the NASDAQ quotation system, provided your involvement with any such company is solely that of a passive stockholder. For purposes of this Agreement,
“Restricted Business” means the oil and gas exploration and production business in Texas, Oklahoma and New Mexico and each other area, location or field in which the Windsor Companies conduct business, and any other business
or operation that is in competition with any business or operations under consideration or in development by any Windsor Company before the termination of your employment with, engagement as a consultant of, or other affiliation with, any Windsor
Company or any subsidiary of a Windsor Company. 
 (b) The parties hereto intend that the covenant contained in this
Section 6 shall be deemed a series of separate covenants for each state, county and city in which the Windsor Group’s business is conducted or is preparing to be conducted. If, in any judicial proceeding, a court refuses to enforce all of
the separate covenants deemed included in this Section 6 because, taken together, they cover too extensive a geographic area, the parties intend that those covenants (taken in order of the states, counties and cities therein which are least
populous), which if eliminated would permit the remaining separate covenants to be enforced in such proceeding, shall, for the purpose of such proceeding, be deemed eliminated from the provisions of this Section 6. 

7. Confidentiality, Non-Interference, Proprietary Information and Non-Solicitation. 

(a) Confidentiality. In the course of your employment by the Windsor Companies, you have had, and/or shall have, access to
confidential or proprietary data or information of the Windsor Group, Wexford Capital LP (“Wexford”), any affiliates of the foregoing, the investment funds and managed accounts for which Wexford or its affiliates serves as
general partner or acts as investment manager (the “Funds”), entities managed by Wexford or served by the Windsor Group, including without limitation entities in which the Funds have invested, directly or indirectly and their
respective businesses (collectively the “Wexford Parties” and each of them individually, a “Wexford Party,” which for the avoidance of doubt includes the Windsor Group). You shall not at any time
during or after your employment divulge or communicate to any person (which term, for purposes of this Agreement, includes both persons or entities) nor shall you direct any Windsor Group employee to divulge or communicate to any person (other than
to a person bound by confidentiality obligations similar to those contained herein and other than as necessary in performing your duties hereunder), or use to the detriment of the Wexford Parties or for the benefit of any other person, any of such
data or 

  
 5 

 
information. No business conducted by you or any organization of which you, directly or indirectly, are an owner, partner, manager, joint venturer, director, officer, manager or otherwise a
participant in or connected with in any locality, state or country in which the Wexford Parties conduct business shall use any name, designation or logo which is substantially similar to that presently used by any Wexford Party. The term
“confidential or proprietary data or information” as used in this Agreement shall mean information not generally available to the public or generally known within the applicable Wexford Party’s industry, including, without limitation,
personnel information, financial information, customer lists or contacts, supplier lists, strategy and plans, information regarding operations, systems, services, know-how, computer and any other processed or collated data, trade secrets (including,
without limitation, software), computer programs, pricing, marketing and advertising data. 
 (b) Non-Interference.
You agree that, during the Restricted Period, you shall not, at any time or in any manner, either directly or indirectly, for your own account or for the account of any other person, interfere with any Wexford Party’s relationship with any of
its employees, suppliers or regulators. 
 (c) Proprietary Information and Disclosure. You agree that you shall at
all times promptly disclose to the Company, in such form and manner as the Company may require, any inventions, improvements or procedural or methodological innovations, program methods, forms, systems, services, designs, marketing ideas, products
or processes (whether or not capable of being trademarked, copyrighted or patented) conceived or developed or created by you during or in connection with your employment hereunder and which relate to the business of any Wexford Party
(“Intellectual Property”). You agree that all such Intellectual Property constitutes a work-for-hire and shall be the sole property of the applicable Wexford Party. You further agree that you shall execute such instruments
and perform such acts as may be requested by the Company to transfer to and perfect in the entity designated by the Company all legally protectable rights in such Intellectual Property. 

(d) Return of Property. All materials, records and documents in any medium made by you or coming into your possession during
your employment concerning any products, processes or services, manufactured, used, developed, investigated, provided or considered by any Wexford Party or otherwise concerning the business or affairs of the Wexford Parties, shall be the sole
property of the applicable Wexford Party, and upon termination of your employment, or upon request of the Company during your employment, you shall promptly deliver the same to the Wexford Party designated by the Company. In addition, upon
termination of your employment, or upon request of the Company during your employment, you shall deliver to the Wexford Party designated by the Company all other property of the Wexford Parties in your possession or under your control, including,
but not limited to, financial statements, marketing and sales data, drawings, documents and electronic records. 
 (e) No
Solicitation of Customers. Notwithstanding any other provision of this Agreement, you agree that, during the Restricted Period, you shall not at any time or in any manner, on your own behalf, or on behalf of any other individual, sole
proprietorship, business, firm, partnership, company, corporation or other entity other than the Company, directly solicit, or ask anyone else to solicit, the sale of goods, services or a combination of goods and services, which are the same or
similar to those provided by the Windsor Group, from Established 

  
 6 

 
Customers. You further agree that for the same period, you will not in any way interfere or attempt to interfere with the Windsor Group’s relationships with any of their Established
Customers. “Established Customers” means any customer that the Windsor Group has actually done business with during the twelve (12) months preceding the date of termination of your employment with, engagement as a consultant of, or
other affiliation with, any Windsor Company. 
 (f) Non Solicitation of Employees. Notwithstanding any other
provision of this Agreement, you agree that, during the Restricted Period, you shall not at any time or in any manner, either directly or indirectly, either on your behalf or on behalf of any person (other than the Windsor Group), recruit, solicit,
hire, divert or otherwise encourage or attempt to recruit, solicit, hire, divert or otherwise encourage any officer or employees or agents of any Windsor Company to enter into any employment, consulting or advisory arrangement or contract with or to
perform any services for or on your behalf or on behalf of any person (other than the Windsor Group), or to enter into any kind of business with you or any other person, including, without limitation, any Restricted Business, the business of any
Windsor Company or any business similar to that of a Windsor Company, or hire any such officer or key employee or agent. 
 (g)
Non-Disparagement. You agree not to make public statements, negative comments or otherwise disparage any Wexford Party or any Wexford Party’s officers, directors, employees, agents, shareholders or other equity holders in any
manner likely to be harmful to them or their business, business reputation or personal reputation. The foregoing shall not be violated by truthful statements in response to legal process, required governmental testimony or filings, or administrative
or arbitral proceedings (including, without limitation, depositions in connection with such proceedings). 
 (h)
Cooperation. Upon the receipt of reasonable notice from the Company (including outside counsel), you agree that while employed by any Windsor Company and thereafter, you shall provide reasonable assistance to any Wexford Party and
their respective representatives in defense of any claims that may be made against any Wexford Party, and shall assist any Wexford Party in the prosecution of any claims that may be made by any Wexford Party, to the extent that such claims relate to
the period of your employment with a Windsor Company. You agree to promptly inform the Company if you become aware of any lawsuits involving such claims that may be filed or threatened against any Wexford Party. You also agree to promptly inform the
Company (to the extent legally permitted to do so) if you are asked to assist in any investigation of any Wexford Party (or its actions), regardless of whether a lawsuit or other proceeding has then been filed against any Wexford Party with respect
to such investigation. Upon presentation of appropriate documentation, the Company shall pay or reimburse you for all reasonable out-of-pocket expenses incurred by you in complying with this Section 7(h). If at the time of compliance you are no
longer an employee, officer or director (or functional equivalent) of any Windsor Company, the Company shall provide a reasonable per diem to you. 

  
 7 

 8. Interpretation, Enforcement and Construction 

(a) Equitable Relief. With respect to the covenants contained in Sections 6 and 7 of this Agreement, you agree that any
remedy at law for any breach of said covenants may be inadequate and that the Company shall be entitled to specific performance or any other mode of injunctive and/or other equitable relief to enforce its rights hereunder or any other relief a court
might award. In the event of a violation by you of Section 6 or Section 7 hereof, any compensation being paid to you pursuant to this Agreement or otherwise shall immediately cease, and any Base Salary previously paid to you after
termination of your employment shall be immediately repaid to the Company. The amount of any earned Base Salary paid for the period prior to termination of your employment shall be retained by you. 

(b) Reformation. The agreements made in Sections 6 and 7 are material inducements for you to enter into this
Agreement and the Company would not have made this Agreement with you without such assurances. You understand and agree that the geographic area applicable to Section 6 is based on the nature of the products and services provided by the Windsor
Group and the broad distribution of their customers, and that the limitations set forth therein are reasonable in geographic area and time and necessary for the protection of the Windsor Group and its goodwill. However, if any court determines that
the time, geographic area or scope of activity of any restriction contained in Section 6 is unenforceable, it is our intention that such limitation set forth herein shall not be terminated but shall be amended to the extent required to render
it valid and enforceable. A court hearing any such dispute is empowered and authorized by the parties to reform this Agreement to the maximum time, scope or geographic limitations permitted by applicable law 

9. Earlier Termination. Your employment shall terminate prior to the expiration of the Term on the following
terms and conditions: 
 (a) Death or Disability. Your employment shall terminate automatically on the date of your
death or immediately upon the Company’s sending you a notice of termination for “Disability”, which shall mean your inability to perform your duties hereunder for ninety (90) days (whether or not continuous) during
any period of three hundred sixty-five (365) consecutive days by reason of physical or mental disability. Upon termination of your employment for death or Disability pursuant to this Section 9(a), the Company’s sole obligations to you
shall be, subject to your compliance with the provisions of Sections 6 and 7 hereof, to (i) pay your Base Salary for the remainder of the Term, which shall be paid as and when such amounts would have been due had your employment continued,
(ii) honor any obligations of the Company with respect to the Purchase Option or Diamondback Option, as applicable, under Sections 2(c) and (d) hereof, and (iii) pay the prorated portion of the minimum Annual Bonus for the period of
the applicable fiscal prior to the effective date of such termination. 
 (b) Resignation Not for Good Reason; Termination
for Cause. Your employment shall terminate (x) no less than thirty (30) days after you send the Company written notice of such termination or (y) immediately upon the Company’s sending you written notice terminating your
employment hereunder for Cause (as defined below), and you and the Company shall have no further obligations hereunder other than your obligations under Sections 6 and 7 hereof and the Company’s obligation to pay you any of your accrued but
unpaid Base Salary through the date of termination and honor any of its obligations with respect to the vested portion of any Purchase Option or Diamondback Option, as applicable, under Sections 2(c) and (d) hereof.
“Cause” shall mean (A) your willful and knowing refusal or failure (other than during periods of illness, physical or mental incapacity) to perform your duties in any material respect

  
 8 

 
under this Agreement; (B) your willful misconduct or gross negligence in the performance of your duties; (C) your material breach of this Agreement, any other agreement entered into by
you related to the Company or its affiliates, or any Company or Windsor Group policy (including any applicable code of conduct); (D) your breach of Sections 6 or 7 of this Agreement; (E) your conviction of, entry of a guilty plea or a plea
of nolo contendere to any criminal act that constitutes a felony or involves, fraud, dishonesty, or moral turpitude; (F) your indictment for any felony involving embezzlement or theft or fraud; (G) your filing of a voluntary
petition in bankruptcy or your consent to an involuntary petition in bankruptcy (or your failure to vacate, within ninety (90) days of the entry thereof, any order approving an involuntary petition in bankruptcy) or the entry of an order,
judgment or decree by any court of competent jurisdiction, on the application of a creditor, adjudicating you as bankrupt or insolvent or the appointment of a receiver, trustee, or liquidator of all or a substantial part of your assets, and such
order, judgment or decree’s continuing unstayed and in effect for any period of ninety (90) days; (H) your dishonesty in connection with your responsibilities as an employee; or (I) your failure to comply with any lawful
directive of the Board after five (5) business days written notice to you. Upon termination of your employment pursuant to this Section 9(b), the Company shall have no obligations hereunder. If you terminate your employment pursuant to
clause (x) hereof, the Company shall be entitled to accelerate the effectiveness of the termination of your employment to whatever time and date as it designates in writing to you in its sole discretion. 

(c) Resignation for Good Reason; Termination Without Cause. Your employment shall terminate immediately upon the
Company’s sending you written notice terminating your employment hereunder (without Cause therefor having been given by you) for any reason or for no reason (a “No Cause Termination”) or upon your resignation in the
event of any (i) material breach by the Company hereunder or (ii) material diminution in the your position, duties, or authority, which in either case is not cured within thirty (30) business days after written notice thereof by you
to the Board (which notice must be provided by you to the Company within 90 days following the initial occurrence of such event) and an opportunity to cure within the notice period (collectively, “Good Reason Resignation”).
Any termination on account of a Good Reason Resignation must occur within two years following the initial occurrence of such event. Upon any such No Cause Termination or Good Reason Resignation, as the case may be, the Company’s sole
obligation(s) to you shall be (x) in the case of a No Cause Termination or your Good Reason Resignation under this Section 9(c), to pay you your Base Salary for the remainder of the Term, which, subject to the timing requirements specified
in Section 22, including without limitation Section 22(c)(ii), shall be paid as and when such amounts would have been due had your employment continued and (y) in the case of a No Cause Termination, to honor any obligations of the
Company with respect to the Company Option or Diamondback Option, as applicable, under Sections 2(c) and (d) hereof; provided that any such payment shall be subject to your continued compliance with the provisions of Sections 6 and 7 hereof and
your executing (and not revoking) a full general release in a form as requested by the Company, releasing all claims, known or unknown, that you may have against any Wexford Party, their officers, directors, employees and agents, arising out of or
any way related to your employment or termination of employment with the Company; provided further that, for the purposes of this Section 9(c) only, the Restricted Period under Section 6 shall end on the last day of the Term. In the event
Employee refuses to sign and/or revokes any such full general release within the 60 day period following the date of termination, Employee acknowledges and agrees 

  
 9 

 
that Employee shall not be entitled to any Base Salary continuation payments so that the Company shall have no further obligation to compensate Executive under this Agreement for termination of
employment other than paying earned but unpaid salary and accrued vacation. Payments provided in this Section 9(c) shall be in lieu of any termination or severance payments or benefits for which you may be eligible under any of the plans,
policies or programs of the Company or its affiliates or under the WARN Act or any similar state statute or regulation. If you accept other employment or engage in your own business prior to the last date of the Term, you agree to and shall promptly
notify the Company. 
 (d) Continuation of Employment. Any continued employment with the Company during and after
the Term is “at-will”, meaning you have the right at any time, and for any reason or no reason, to terminate your employment with or without notice, and the Company has the same right. You understand and agree the Company shall not be
obligated to continue your employment prior to the expiration of the Term. Any continuation of employment after the Term shall be on such terms and conditions as the Company may then offer. 

(e) No Other Obligation. Except as specifically set forth in Sections 9(a) and 9(c) above, upon termination of your
employment under this Agreement, the Company’s obligations hereunder shall cease and neither the Company nor, for the avoidance of doubt, any other Windsor Company, shall have any further obligations to you whatsoever. 

10. Representation and Warranty. You represent that you do not have any contractual or other obligations that would
conflict with your employment by the Company. In particular, you represent that you are not bound by any agreement, understanding or other obligation with or to any person or entity (including, without limitation, any confidentiality,
non-competition or non-solicitation agreement) that prohibits you from accepting or continuing your employment by the Company and fully performing all of your duties for the Company. You also acknowledge that it is the Company’s policy to
respect the legal rights of others to protect their confidential information. You therefore represent that you have not taken or retained any confidential information (or other property) belonging to a prior employer and shall not use or disclose
any such confidential information in connection with your work for the Company. Any inaccuracy of any of the statements set forth in this Section 10 shall constitute “Cause” for purposes of this Agreement, in which event we would be
entitled to terminate your employment under Section 9(b) above with the effect set forth therein. 
 11. Dealings
with Related Parties. You shall not engage in any dealings on behalf of any Windsor Company with any party in which you or any person or entity affiliated with you, or members of your or their respective immediate families, has a financial
interest, without first disclosing same to the Board in a writing specifically describing the nature of the interest and obtaining the Company’s prior written approval. 
 12. Entire Agreement; Modification. This Agreement constitutes the full and complete understanding of the parties with respect to your employment arrangements with the Company and any of its
affiliates and shall, on the Effective Date, supersede all prior agreements and writings between you, on the one hand, and the Company or any other Windsor Company (or any of their respective predecessors), on the other hand, with respect to your
employment arrangements with the Company or any of its affiliates (the “Prior Agreements”). You and the 

  
 10 

 
Company hereby respectively release each other and the Company’s affiliates, effective as of the Effective Date, from all obligations to the other party under the Prior Agreements. No
representations, inducements, promises, agreements or understandings, oral or otherwise, have been made by either party to this Agreement, or anyone acting on behalf of either party, which are not set forth herein and any others are specifically
waived. This Agreement may not be amended or modified in any manner nor may any of its provisions be waived except by written amendment executed by the parties. A waiver, modification or amendment by a party shall only be effective if (a) it is
in writing and signed by the parties, (b) it specifically refers to this Agreement and (c) it specifically states that the party, as the case may be, is waiving, modifying or amending its rights hereunder. Any such amendment, modification
or waiver shall be effective only in the specific instance and for the specific purpose for which it was given. 
 13.
Severability. The terms and provisions of this Agreement shall be deemed severable, and the invalidity or unenforceability of any one or more of the provisions hereof shall not affect the validity or enforceability of any one or more
of the other provisions hereof. In the event any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction, as to such jurisdiction, shall be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction and the parties agree the conflicting
term or provision shall be modified to conform.

disposition of your right to compensation or other benefits will be null and void. This Agreement shall be binding upon and inure to the benefit of you, your legal representatives, heirs and distributees, and shall be binding upon and inure to the
benefit of the Company, its affiliates and their respective successors and assigns, including, without limitation, those by asset assignment, stock sale, merger, consolidation or other reorganization (each a “Permitted Assignee”). The

 16. Governing Law; Venue; Waiver of Trial by Jury. 

(a) This Agreement and the rights of the parties hereunder shall be governed by, interpreted, and enforced in accordance with the internal
laws of the State of Texas without giving effect to any choice of law or conflicts of law rules or provisions thereof. 
 (b)
Each party irrevocably agrees that any action or proceeding involving any dispute or matter arising under this Agreement may only be brought in the federal courts of the State of Texas, or if such court does not have jurisdiction or shall not accept
jurisdiction, in any court of general jurisdiction in the State of Texas. All parties hereby irrevocably consent to the exclusive jurisdiction by any such court with respect to any such proceeding and hereby irrevocably waives, and agrees not to
assert, by way of motion, as a defense, counterclaim or otherwise (i) any claim that it is not personally subject to the jurisdiction of the above-named courts for any reason other than by failure to lawfully serve process, (ii) that it or
its property is exempt or immune from the jurisdiction of any such court or from any legal process commenced in such courts, and (iii) to the fullest extent permitted by applicable law, that (x) the action or proceeding is brought in an
inconvenient forum, (y) the venue of such action or proceeding is improper and (z) this Agreement or the subject matter thereof may not be enforced in or by such courts. 

(c) To the extent not prohibited by applicable law, each party to this Agreement hereby waives, and covenants that it shall not assert
(whether as plaintiff, defendant or otherwise), its respective right to a jury trial of any permitted claim or cause of action arising out of this Agreement, any of the transactions contemplated hereby, or any dealings between any of the parties
hereto relating to the subject matter of this Agreement or any of the transactions contemplated hereby. The scope of this waiver and covenant is intended to be all encompassing of any and all disputes that may be filed in any court and that relate
to the subject matter of this Agreement or any of the transactions contemplated hereby, including, contract claims, tort claims and all other common law and statutory claims. This waiver and covenant is irrevocable and shall apply to any subsequent
amendments, supplements or other modifications to this Agreement. 
 17. Prevailing Party Expenses. In the event
that litigation or other legal action is instituted between you and the Company or any of its affiliates to enforce the rights under this Agreement, the successful party in such litigation or other legal action shall be entitled to reimbursement
from the unsuccessful party in such litigation or other legal action of all reasonable fees, costs and expenses (including court costs and reasonable attorneys’ fees) incurred by such successful party in connection with such litigation or other
legal action. 
 18. Third Party Beneficiaries. Wexford and its successors and assigns, as express third party
beneficiaries of this Agreement, shall be entitled, in their sole and absolute discretion, to enforce any of the provisions hereof from time to time, including, but not limited to, the restrictions set forth in Sections 6 and 7 of this Agreement.

 19. Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are
not to be considered in construing or interpreting this Agreement. 

  
 12 

 20. Counterparts; Facsimile. This Agreement may be executed and delivered by
facsimile signature and in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. 
 21. Review of this Agreement. You acknowledge that you have (a) carefully read this Agreement, (b) consulted with independent counsel with respect to this Agreement and
(c) entered into this Agreement of your own free will. 
 22. Tax Matters; Code Section 409A Compliance.

 (a) Deferred Compensation Exceptions. Payments under this Agreement will be administered and interpreted to
maximize the short-term deferral exception to and the involuntary separation pay exception under Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and the regulations thereunder (collectively
“Section 409A”). The portion of any payment under this Agreement that is paid within the short-term deferral period (within the meaning of Code Section 409A and Treas. Regs. §1.409A-1(b)(4)) or that is paid within
the involuntary separation pay safe harbor (as described in Code Section 409A and Treas. Regs. §1.409A-1(b)(9)(iii)) will not be treated as nonqualified deferred compensation and will not be aggregated with other nonqualified deferred
compensation plans or payments. 
 (b) Separate Payments and Payment Timing. Any payment or installment made under
this Agreement and any amount that is paid as a short-term deferral, within the meaning of Treas. Regs. §1.409A-1(b)(4), will be treated as separate payments. Employee will not, directly or indirectly, designate the taxable year of a payment
made under this Agreement. Payment dates provided for in this Agreement will be deemed to incorporate grace periods that are treated as made upon a designated payment date within the meaning of Code Section 409A and Treas. Regs.
§1.409A-3(d). 
 (c) General 409A Provisions. If for any reason, the short-term deferral or involuntary
separation pay plan exception is inapplicable, payments and benefits payable to Employee under this Agreement are intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”).
To the extent the payments and benefits under this Agreement are subject to Section 409A of the Code, this Agreement will be interpreted, construed and administered in a manner that satisfies the requirements of Sections 409A(a)(2),
(3) and (4) of the Code and the Treasury Regulations thereunder (and any applicable transition relief under Section 409A of the Code). The Company does not guaranty or warrant the tax consequences of this Agreement and, except as
specifically provided to the contrary in this Agreement, Employee will, in all cases, be liable for any taxes due as a result of this Agreement. Neither the Company nor any of its affiliates will have any obligation to indemnify or otherwise hold
you harmless from any or all such taxes, interest or penalties, or liability for any damages related thereto. Employee acknowledges that he has been advised to obtain independent legal, tax or other counsel in connection with Section 409A.

 (i) If Employee or the Company determines that any payments or benefits payable under this Agreement intended
to comply with Sections 409A(a)(2), (3) and (4) of the Code do not comply with Section 409A of the Code, Employee and the Company agree to amend this Agreement, or take such other actions as Employee and the

  
 13 

 
Company deem reasonably necessary or appropriate, to comply with the requirements of Section 409A of the Code, the Treasury Regulations thereunder (and any applicable relief provisions)
while preserving the economic agreement of the parties. If any provision of the Agreement would cause such payments or benefits to fail to so comply, such provision will not be effective and will be null and void with respect to such payments or
benefits, and such provision will otherwise remain in full force and effect. 
 (ii) All payments considered
nonqualified deferred compensation under Section 409A and the regulations thereunder will be made on the date(s) provided herein and no request to accelerate or defer any payment under this Section will be considered or approved for any reason
whatsoever, except as permitted under Section 409A. The Base Salary continuation payments will commence on the first payroll date that is on or after the eighth day following receipt by the Company of Employee’s executed release; provided,
however, if the Base Salary continuation payments are deferred compensation subject to Code Section 409A and if the period during which Employee has discretion to execute or revoke the release straddles two taxable years of Employee, then the
Company will commence the Base Salary continuation payments in the second of such taxable years. Notwithstanding the foregoing, subject to the release requirement, the Base Salary continuation payments will in all events be paid no later than 60
days following Executive’s termination of employment, regardless of which taxable year Executive actually delivers the executed Release to the Company. Once such Base Salary continuation payments commence, the first installment thereof will
include all amounts that would have been paid had such payments commenced on the first payroll date occurring on or after the termination of employment date. Executive may not, directly or indirectly, designate the calendar year of the commencement
of any payment hereunder. Notwithstanding the foregoing, amounts payable hereunder which are not nonqualified deferred compensation, or which may be accelerated pursuant to Section 409A, such as distributions for applicable tax payments, may be
accelerated, but not deferred, at the sole discretion of Company. 
 (iii) All references in this Agreement to
termination of employment or termination mean Employee’s “separation from service” as that term is defined in Section 1.409A-1(h) of the Treasury Regulations. 

(iv) All reimbursements and in-kind benefits provided under this Agreement that constitute deferred compensation within
the meaning of Section 409A of the Code shall be made or provided in accordance with the requirements of Section 409A of the Code, including that (i) in no event shall reimbursements by the Company under this Agreement be made later
than the end of the calendar year next following the calendar year in which the applicable fees and expenses were incurred, provided that you shall have submitted an invoice for such fees and expenses at least 10 days before the end of the calendar
year next following the calendar year in which such fees and expenses were incurred; (ii) the amount of in-kind benefits that the Company is obligated to pay or provide in any given calendar year (other than medical reimbursements described in
Treas. Reg. § 1.409A-3(i)(1)(iv)(B)) shall not affect the in-kind benefits that the Company is obligated to pay or provide in any other calendar year; (iii) your right to have the Company pay or provide such reimbursements and in-kind
benefits may not be liquidated or exchanged for any other benefit; and (iv) in no event shall the Company’s obligations to make such reimbursements or to provide such in-kind benefits apply later than your remaining lifetime or, if longer,
through the 20th anniversary of the Effective Date. 

  
 14 

 (d) Specified Employee Status. If Employee is a specified employee (within the
meaning of Code Section 409A) on the date of his separation from service, any payments made with respect to such separation from service under this Agreement, and other payments or benefits under this Agreement that are subject to
Section 409A of the Code, will be delayed in order to comply with Section 409A(a)(2)(B)(i) of the Code, and such payments or benefits will be paid or distributed to you during the five-day period commencing on the earlier of: (i) the
expiration of the six-month period measured from the date of your separation from service, or (ii) the date of your death. Upon the expiration of the applicable six-month period under Section 409A(a)(2)(B)(i) of the Code, all payments
deferred pursuant to this Section (e) will be paid to Employee (or Employee’s estate, in the event of Employee’s death) in a lump sum payment. Any remaining payments and benefits due under the Agreement will be paid as otherwise
provided in the Agreement. 
 (e) Withholding Taxes. To the extent any payments under this Agreement are wages
subject to income and employment tax withholding, the Company has the right to withhold or otherwise require Executive to pay to the Company the amount of any taxes that the Company may be required to withhold before delivery of such payment to
Executive. 
 23. Background Verification. You hereby authorize the Company to conduct one or more Background
Verifications prior to and during your actual employment. “Background Verification” includes, without limitation, information regarding your employment and other experience, educational background and any criminal, credit or
regulatory history. You further authorize, without reservation, any law enforcement agency, administrator, court, governmental body, federal or provincial agency, institution, school or university (public or private), information service bureau,
employer or insurance company contacted by the Company or any agent of the Company to furnish the information set forth in the preceding sentence as part of the employment application process. You hereby consent to and understand that the Company
will only use the information collected for the purposes of (if and as applicable) establishing or continuing your employment, including without limitation, evaluating your employment application, determining employment eligibility under the
Company’s employment policies, assessing property and business risks to the Company, and otherwise as may be permitted or required by law. You authorize and consent to the release of records obtained through such checks to the authorized
representatives of the Company or its agents, and to the Company’s affiliates, for the purposes described above. You acknowledge and agree that any information relating to a Background Verification may be shared with any Wexford Party and
stored on the respective servers. 
 24. Survival. The obligations of Sections 6, 7, 8, 14, 16 and 17 shall
expressly survive any expiration or termination of this Agreement.

ARTICLE II 

The Credits 
 Section 2.01 Commitments. Subject to the terms and conditions set forth herein, each Lender agrees to make Loans to the Borrower during the Availability Period in an aggregate principal amount
that will not result in (a) such Lender’s Revolving Credit Exposure exceeding such Lender’s Commitment or (b) the total Revolving Credit Exposures exceeding the total Commitments. Within the foregoing limits and subject to the
terms and conditions set forth herein, the Borrower may borrow, repay and reborrow the Loans. 
 Section 2.02 Loans and
Borrowings. 
 (a) Borrowings; Several Obligations. Each Loan shall be made as part of a Borrowing consisting of Loans
made by the Lenders ratably in accordance with their respective Commitments. The failure of any Lender to make any Loan required to be made by it shall not relieve any other Lender of its obligations hereunder; provided that the Commitments are
several and no Lender shall be responsible for any other Lender’s failure to make Loans as required. 

  
 23 

 (b) Types of Loans. Subject to Section 3.03, each Borrowing shall be comprised
entirely of ABR Loans or Eurodollar Loans as the Borrower may request in accordance herewith. Each Lender at its option may make any Eurodollar Loan by causing any domestic or foreign branch or Affiliate of such Lender to make such Loan; provided
that any exercise of such option shall not affect the obligation of the Borrower to repay such Loan in accordance with the terms of this Agreement. 
 (c) Minimum Amounts; Limitation on Number of Borrowings. At the commencement of each Interest Period for any Eurodollar Borrowing, such Borrowing shall be in an aggregate amount that is an integral
multiple of $250,000 and not less than $250,000. At the time that each ABR Borrowing is made, such Borrowing shall be in an aggregate amount that is an integral multiple of $250,000 and not less than $250,000; provided that, notwithstanding the
foregoing, an ABR Borrowing may be in an aggregate amount that is equal to the entire unused balance of the total Commitments or that is required to finance the reimbursement of an LC Disbursement as contemplated by Section 2.08(e). Borrowings
of more than one Type may be outstanding at the same time, provided that there shall not at any time be more than a total of five (5) Eurodollar Borrowings outstanding. Notwithstanding any other provision of this Agreement, the Borrower shall
not be entitled to request, or to elect to convert or continue, any Borrowing if the Interest Period requested with respect thereto would end after the Maturity Date. 
 (d) Notes. The Loans made by each Lender shall be evidenced by a single promissory note of the Borrower in substantially the form of Exhibit A, dated, in the case of (i) any Lender party
hereto as of the date of this Agreement, as of the date of this Agreement or (ii) any Lender that becomes a party hereto pursuant to an Assignment and Assumption, as of the effective date of the Assignment and Assumption, payable to such Lender
in a principal amount equal to its Maximum Credit Amount as in effect on such date, and otherwise duly completed. In the event that any Lender’s Maximum Credit Amount increases or decreases for any reason (whether pursuant to Section 2.06,
Section 12.04(b) or otherwise), the Borrower shall deliver or cause to be delivered on the effective date of such increase or decrease, a new Note payable to such Lender in a principal amount equal to its Maximum Credit Amount after giving
effect to such increase or decrease, and otherwise duly completed. The date, amount, Type, interest rate and, if applicable, Interest Period of each Loan made by each Lender, and all payments made on account of the principal thereof, shall be
recorded by such Lender on its books for its Note, and, prior to any transfer, may be endorsed by such Lender on a schedule attached to such Note or any continuation thereof or on any separate record maintained by such Lender. Failure to make any
such notation or to attach a schedule shall not affect any Lender’s or the Borrower’s rights or obligations in respect of such Loans or affect the validity of such transfer by any Lender of its Note. 

(e) Loans and Borrowings under the Existing Credit Agreement. On the Effective Date: 

(i) the Borrower shall pay all accrued and unpaid commitment fees, break funding fees under Section 5.02 and all other fees that
are outstanding under the Existing Credit Agreement for the account of each “Lender” under the Existing Credit Agreement; 

  
 24 

 (ii) each “ABR Loan” and “Eurodollar Loan” outstanding under the
Existing Credit Agreement shall be deemed to be continued as existing Loans under this Agreement and not as a novation; 

(iii) any letters of credit outstanding under the Existing Credit Agreement shall be deemed issued under this Agreement; and 

(iv) the Existing Credit Agreement and the commitments thereunder shall be superseded by this Agreement. 

It is the intent of the parties hereto that this Agreement not constitute a novation of the obligations and liabilities existing under
the Existing Credit Agreement or evidence repayment of any such obligations and liabilities and that this Agreement amend and restate in its entirety the Existing Credit Agreement and re-evidence the obligations of the Borrower outstanding
thereunder. 
 Section 2.03 Requests for Borrowings. To request a Borrowing, the Borrower shall notify the
Administrative Agent of such request by telephone (a) in the case of a Eurodollar Borrowing, not later than 12:00 noon, Houston, Texas time, three Business Days before the date of the proposed Borrowing or (b) in the case of an ABR
Borrowing, not later than 12:00 noon, Houston, Texas time, one Business Day before the date of the proposed Borrowing; provided that no such notice shall be required for any deemed request of an ABR Borrowing to finance the reimbursement of an LC
Disbursement as provided in Section 2.08(e). Each such telephonic Borrowing Request shall be irrevocable and shall be confirmed promptly by hand delivery, electronic communication or telecopy to the Administrative Agent of a written Borrowing
Request in substantially the form of Exhibit B and signed by the Parent Guarantor and the Borrower. Each such telephonic and written Borrowing Request shall specify the following information in compliance with Section 2.02: 

(i) the aggregate amount of the requested Borrowing; 
 (ii) the date of such Borrowing, which shall be a Business Day; 
 (iii) whether
such Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; 
 (iv) in the case of a Eurodollar Borrowing, the initial
Interest Period to be applicable thereto, which shall be a period contemplated by the definition of the term “Interest Period”; 
 (v) the amount of the then effective Borrowing Base, the current total Revolving Credit Exposures (without regard to the requested Borrowing) and the pro forma total Revolving Credit Exposures
(giving effect to the requested Borrowing); and 
 (vi) the location and number of the Borrower’s account to which funds
are to be disbursed, which shall comply with the requirements of Section 2.05. 

  
 25 

 If no election as to the Type of Borrowing is specified, then the requested Borrowing shall be an ABR
Borrowing. If no Interest Period is specified with respect to any requested Eurodollar Borrowing, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration. Each Borrowing Request shall constitute a
representation that the amount of the requested Borrowing shall not cause the total Revolving Credit Exposures to exceed the total Commitments (i.e., the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base).

 Promptly following receipt of a Borrowing Request in accordance with this Section 2.03, the Administrative Agent shall advise each
Lender of the details thereof and of the amount of such Lender’s Loan to be made as part of the requested Borrowing. 

Section 2.04 Interest Elections. 
 (a) Conversion and Continuance. Each Borrowing initially shall be of the Type specified in the applicable Borrowing Request and, in the case of a Eurodollar Borrowing, shall have an initial
Interest Period as specified in such Borrowing Request. Thereafter, the Borrower may elect to convert such Borrowing to a different Type or to continue such Borrowing and, in the case of a Eurodollar Borrowing, may elect Interest Periods therefor,
all as provided in this Section 2.04. The Borrower may elect different options with respect to different portions of the affected Borrowing, in which case each such portion shall be allocated ratably among the Lenders holding the Loans
comprising such Borrowing, and the Loans comprising each such portion shall be considered a separate Borrowing. 
 (b)
Interest Election Requests. To make an election pursuant to this Section 2.04, the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under
Section 2.03 if the Borrower was requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed
promptly by hand delivery, electronic communication or telecopy to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit C and signed by the Parent Guarantor and the Borrower. 

(c) Information in Interest Election Requests. Each telephonic and written Interest Election Request shall specify the following
information in compliance with Section 2.02: 
 (i) the Borrowing to which such Interest Election Request applies and, if
different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.04(c)(iii) and (iv) shall
be specified for each resulting Borrowing); 
 (ii) the effective date of the election made pursuant to such Interest Election
Request, which shall be a Business Day; 
 (iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar
Borrowing; and 

  
 26 

 (iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be
applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”. 
 If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s
duration. 
 (d) Notice to Lenders by the Administrative Agent. Promptly following receipt of an Interest Election
Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing. 
 (e) Effect of Failure to Deliver Timely Interest Election Request and Events of Default and Borrowing Base Deficiencies on Interest Election. If the Borrower fails to deliver a timely Interest
Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to a
Eurodollar Borrowing with an Interest Period of one month’s duration. Notwithstanding any contrary provision hereof, if an Event of Default or a Borrowing Base Deficiency has occurred and is continuing: (i) no outstanding Borrowing may be
converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and (ii) unless repaid,
each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto. 

Section 2.05 Funding of Borrowings. 
 (a) Funding by Lenders. Each Lender shall make each Loan to be made by it hereunder on the proposed date thereof by wire transfer of immediately available funds by 1:00 p.m., Houston, Texas time,
to the account of the Administrative Agent most recently designated by it for such purpose by notice to the Lenders. The Administrative Agent will make such Loans available to the Borrower by promptly crediting the amounts so received, in like
funds, to an account of the Borrower maintained with the Administrative Agent in Houston, Texas and designated by the Borrower in the applicable Borrowing Request; provided that ABR Loans made to finance the reimbursement of an LC Disbursement as
provided in Section 2.08(e) shall be remitted by the Administrative Agent to the Issuing Bank. Nothing herein shall be deemed to obligate any Lender to obtain the funds for its Loan in any particular place or manner or to constitute a
representation by any Lender that it has obtained or will obtain the funds for its Loan in any particular place or manner. 

(b) Presumption of Funding by the Lenders. Unless the Administrative Agent shall have received notice from a Lender prior to the
proposed date of any Borrowing that such Lender will not make available to the Administrative Agent such Lender’s share of such Borrowing, the Administrative Agent may assume that such Lender has made such share available on such date in
accordance with Section 2.05(a) and may, in reliance upon such assumption, make available to the Borrower a corresponding amount. In such event, if a Lender has not in fact made its share of the applicable Borrowing available to the
Administrative Agent, 

  
 27 

 
then the applicable Lender and the Borrower severally agree to pay to the Administrative Agent forthwith on demand such corresponding amount with interest thereon, for each day from and including
the date such amount is made available to the Borrower to but excluding the date of payment to the Administrative Agent, at (i) in the case of such Lender, the greater of the Federal Funds Effective Rate and a rate determined by the
Administrative Agent in accordance with banking industry rules on interbank compensation or (ii) in the case of the Borrower, the interest rate applicable to ABR Loans. If such Lender pays such amount to the Administrative Agent, then such
amount shall constitute such Lender’s Loan included in such Borrowing. 
 Section 2.06 Termination and Reduction of
Aggregate Maximum Credit Amounts. 
 (a) Scheduled Termination of Commitments. Unless previously terminated, the
Commitments shall terminate on the Maturity Date. If at any time the Aggregate Maximum Credit Amounts or the Borrowing Base is terminated or reduced to zero, then the Commitments shall terminate on the effective date of such termination or
reduction. 
 (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 Maximum Credit Amounts; provided that
(A) each reduction of the Aggregate Maximum Credit Amounts shall be in an amount that is an integral multiple of $1,000,000 and not less than $1,000,000 and (B) the Borrower shall not terminate or reduce the Aggregate Maximum Credit
Amounts if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 3.04(c), the total Revolving Credit Exposures would exceed the total Commitments. 

(ii) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Aggregate Maximum Credit Amounts
under Section 2.06(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 2.06(b)(ii) shall be irrevocable. Any termination or reduction of the Aggregate Maximum Credit Amounts shall be permanent and may
not be reinstated. Each reduction of the Aggregate Maximum Credit Amounts shall be made ratably among the Lenders in accordance with each Lender’s Applicable Percentage. 
 Section 2.07 Borrowing Base. 
 (a) Initial Borrowing Base. For
the period from and including the Effective Date to but excluding the next Redetermination Date, the amount of the Conforming Borrowing Base shall be $90,000,000 and the Non-Conforming Borrowing Base shall be $10,000,000. After the Non-Conforming
Period, the Non-Conforming Borrowing Base shall be $0.0. During the Non-Conforming Period, the Borrowing Base shall be the sum of the Conforming Borrowing Base and the Non-Conforming Borrowing Base and thereafter the Borrowing Base shall equal the
Conforming Borrowing Base. Notwithstanding the foregoing, the Conforming Borrowing Base and the Non-Conforming Borrowing Base (but only during the Non-Conforming Period) may be subject to further adjustments from time to time pursuant to
Section 2.07(e), Section 2.07(f), Section 8.13(c) or Section 9.12(d). 

  
 28 

 (b) Scheduled and Interim Redeterminations. The Conforming Borrowing Base and the
Non-Conforming Borrowing Base (during the Non-Conforming Period) shall be redetermined semi-annually in accordance with this Section 2.07 (a “Scheduled Redetermination”), and, subject to Section 2.07(d), such redetermined
Conforming Borrowing Base and Non-Conforming Borrowing Base shall become effective and applicable to the Borrower, the Issuing Bank and the Lenders on April 1st and October 1st of each year, commencing October 1, 2012. In addition,
the Borrower may, by notifying the Administrative Agent thereof, and the Administrative Agent may, at the direction of the Majority Lenders, by notifying the Borrower thereof, three times during any twelve month period, each elect to cause the
Conforming Borrowing Base and the Non-Conforming Borrowing Base (during the Non-Conforming Period) to be redetermined between Scheduled Redeterminations (an “Interim Redetermination”) in accordance with this Section 2.07.

 (c) Scheduled and Interim Redetermination Procedure. 

(i) Each Scheduled Redetermination and each Interim Redetermination shall be effectuated as follows: Upon receipt by the Administrative
Agent of (A) the Reserve Report and the certificate required to be delivered by the Borrower to the Administrative Agent, in the case of a Scheduled Redetermination, pursuant to Section 8.12(a) and (c), and, in the case of an Interim
Redetermination, pursuant to Section 8.12(b) and (c), and (B) such other reports, data and supplemental information, including, without limitation, the information provided pursuant to Section 8.12(c), as may, from time to time, be
reasonably requested by the Majority Lenders (the Reserve Report, such certificate and such other reports, data and supplemental information being the “Engineering Reports”), the Administrative Agent shall evaluate the information
contained in the Engineering Reports and shall, in good faith, propose a new Conforming Borrowing Base and Non-Conforming Borrowing Base (collectively, the “Proposed Borrowing Base”) based upon such information and such other
information (including, without limitation, the status of title information with respect to the Oil and Gas Properties as described in the Engineering Reports and the existence of any other Debt) as the Administrative Agent deems appropriate in its
sole discretion and consistent with its normal oil and gas lending criteria as it exists at the particular time. In no event shall the Proposed Borrowing Base exceed the Aggregate Maximum Credit Amounts. 

(ii) The Administrative Agent shall notify the Borrower and the Lenders of the Proposed Borrowing Base (the “Proposed Borrowing
Base Notice”): 
 (A) in the case of a Scheduled Redetermination (I) if the Administrative Agent shall have
received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on or before the March 15th and September 15th of such year following the date of
delivery or (II) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then promptly after the
Administrative Agent has received complete Engineering Reports from the Borrower and has had a reasonable opportunity to determine the Proposed Borrowing Base in accordance with Section 2.07(c)(i); and 

  
 29 

 (B) in the case of an Interim Redetermination, promptly, and in any event, within fifteen
(15) days after the Administrative Agent has received the required Engineering Reports. 
 (iii) Any Proposed Borrowing
Base that would increase the Conforming Borrowing Base and/or the Non-Conforming Borrowing Base then in effect must be approved or deemed to have been approved by all of the Lenders as provided in this Section 2.07(c)(iii); and any Proposed
Borrowing Base that would decrease or maintain the Conforming Borrowing Base and/or the Non-Conforming Borrowing Base then in effect must be approved or be deemed to have been approved by the Majority Lenders as provided in this
Section 2.07(c)(iii). Upon receipt of the Proposed Borrowing Base Notice, each Lender shall have fifteen (15) days to agree with the Proposed Borrowing Base or disagree with the Proposed Borrowing Base by proposing an alternate Conforming
Borrowing Base and Non-Conforming Borrowing Base, as applicable. If at the end of such fifteen (15) days, any Lender has not communicated its approval or disapproval in writing to the Administrative Agent, such silence shall be deemed to be an
approval of the Proposed Borrowing Base. If, at the end of such 15-day period, all of the Lenders, in the case of a Proposed Borrowing Base that would increase the Conforming Borrowing Base or the Non-Conforming Borrowing Base then in effect, or the
Majority Lenders, in the case of a Proposed Borrowing Base that would decrease or maintain the Conforming Borrowing Base and/or the Non-Conforming Borrowing Base then in effect, have approved or deemed to have approved, as aforesaid, then the
Proposed Borrowing Base shall become the new Conforming Borrowing Base, Non-Conforming Borrowing Base and Borrowing Base, as applicable, effective on the date specified in Section 2.07(d). If, however, at the end of such 15-day period, all of
the Lenders or the Majority Lenders, as applicable, have not approved or deemed to have approved, as aforesaid, then the Administrative Agent shall poll the Lenders to ascertain the highest Conforming Borrowing Base and Non-Conforming Borrowing Base
then acceptable to the number of Lenders sufficient to constitute the Majority Lenders for purposes of this Section 2.07 and, so long as such amount does not increase the Conforming Borrowing Base or Non-Conforming Borrowing Base then in
effect, such amount shall become the new Conforming Borrowing Base and Non-Conforming Borrowing Base, as applicable, effective on the date specified in Section 2.07(d). 
 (d) Effectiveness of a Redetermined Borrowing Base. After a redetermined Conforming Borrowing Base and Non-Conforming Borrowing Base, if applicable, are approved or are deemed to have been approved
by all of the Lenders or the Majority Lenders, as applicable, pursuant to Section 2.07(c)(iii), the Administrative Agent shall notify the Borrower and the Lenders of the amount of the redetermined Conforming Borrowing Base and Non-Conforming
Borrowing Base, if any (the “New Borrowing Base Notice”), and such amounts shall become the new Borrowing Base, effective and applicable to the Borrower, the Administrative Agent, the Issuing Bank and the Lenders: 

(i) in the case of a Scheduled Redetermination, (A) if the Administrative Agent shall have received the Engineering Reports
required to be delivered by the Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the 

  
 30 

 
April 1st or October 1st, as applicable, following such notice, or (B) if the Administrative Agent shall not have received the Engineering Reports required to be delivered by the
Borrower pursuant to Section 8.12(a) and (c) in a timely and complete manner, then on the Business Day next succeeding delivery of such notice; and 
 (ii) in the case of an Interim Redetermination, on the Business Day next succeeding delivery of such notice. 
 Such amounts shall then become the Conforming Borrowing Base and Non-Conforming Borrowing Base, if applicable, until the next Scheduled Redetermination Date, the next Interim Redetermination Date or the
next adjustment to the Borrowing Base under Section 2.07(e), Section 2.07(f), Section 8.13(c), or Section 9.12, whichever occurs first. Notwithstanding the foregoing, no Scheduled Redetermination or Interim Redetermination shall
become effective until the New Borrowing Base Notice related thereto is received by the Borrower. 
 (e) Potential Adjustment
of Borrowing Base Upon Termination of Swap Agreements. If the Borrower or any Subsidiary shall terminate or create any off-setting positions which have the economic effect of terminating any Swap Agreements (regardless of how evidenced) upon
which the Lenders relied in determining the Borrowing Base, and which would affect the Borrowing Base (after giving effect to any replacement Swap Agreements), then, to the extent required by the Majority Lenders within 10 Business Days of such
termination, the Borrowing Base shall be adjusted in an amount determined by the Majority Lenders equal to the economic value of such Swap Agreements. 
 (f) Reduction of Borrowing Base Upon Issuance of Senior Unsecured Notes. Notwithstanding anything to the contrary contained herein, upon each initial issuance of any Senior Unsecured Notes in
accordance with Section 9.02(i)(1), the Borrowing Base then in effect shall be reduced by an amount equal to the product of 0.25 multiplied by the stated principal amount of such Senior Unsecured Notes (without regard to any initial issue
discount), and the Borrowing Base as so reduced shall become the new Borrowing Base immediately upon the date of such issuance, effective and applicable to the Borrower, the Issuing Bank and the Lenders on such date until the next redetermination or
modification thereof hereunder. 
 Section 2.08 Letters of Credit. 

(a) General. Subject to the terms and conditions set forth herein, the Borrower may request the issuance of dollar denominated
Letters of Credit for its own account or for the account of any of its or the Parent Guarantor’s Subsidiaries, in a form reasonably acceptable to the Administrative Agent and the Issuing Bank, at any time and from time to time during the
Availability Period; provided that the Borrower may not request the issuance, amendment, renewal or extension of Letters of Credit hereunder if a Borrowing Base Deficiency exists at such time or would exist as a result thereof. In the event of any
inconsistency between the terms and conditions of this Agreement and the terms and conditions of any form of letter of credit application or other agreement submitted by the Borrower to, or entered into by the Borrower with, the Issuing Bank
relating to any Letter of Credit, the terms and conditions of this Agreement shall control. Notwithstanding anything to the contrary contained in this Agreement, Section 2.08 shall be subject to the terms and conditions of Section 2.09 and
Section 2.10. 

  
 31 

 (b) Notice of Issuance, Amendment, Renewal, Extension; Certain Conditions. To request
the issuance of a Letter of Credit (or the amendment, renewal or extension of an outstanding Letter of Credit), the Borrower shall hand deliver or telecopy (or transmit by electronic communication, if arrangements for doing so have been approved by
the Issuing Bank) to the Issuing Bank and the Administrative Agent (not less than five (5) Business Days in advance of the requested date of issuance, amendment, renewal or extension) a notice: 

(i) requesting the issuance of a Letter of Credit or identifying the Letter of Credit to be amended, renewed or extended; 

(ii) specifying the date of issuance, amendment, renewal or extension (which shall be a Business Day); 

(iii) specifying the date on which such Letter of Credit is to expire (which shall comply with Section 2.08(c)); 

(iv) specifying the amount of such Letter of Credit; 
 (v) specifying the name and address of the beneficiary thereof and such other information as shall be necessary to prepare, amend, renew or extend such Letter of Credit; and 

(vi) specifying the amount of the then effective Borrowing Base and whether a Borrowing Base Deficiency exists at such time, the current
total Revolving Credit Exposures (without regard to the requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit) and the pro forma total Revolving Credit Exposures (giving effect to the
requested Letter of Credit or the requested amendment, renewal or extension of an outstanding Letter of Credit). 
 Each notice shall constitute
a representation that after giving effect to the requested issuance, amendment, renewal or extension, as applicable, (i) the LC Exposure shall not exceed the LC Commitment and (ii) the total Revolving Credit Exposures shall not exceed the
total Commitments (i.e. the lesser of the Aggregate Maximum Credit Amounts and the then effective Borrowing Base). 
 If requested by the
Issuing Bank, the Borrower also shall submit a letter of credit application on the Issuing Bank’s standard form in connection with any request for a Letter of Credit. 
 (c) Expiration Date. Each Letter of Credit shall expire at or prior to the close of business on the earlier of (i) the date fifteen (15) months after the date of the issuance of such
Letter of Credit (or, in the case of any renewal or extension thereof, fifteen (15) months after such renewal or extension) and (ii) the date that is five Business Days prior to the Maturity Date; provided, however, that any Letter of
Credit may provide for the renewal thereof for additional periods, each of which shall not exceed fifteen (15) months (which shall in no event extend beyond the date referred to in clause (ii) above). 

  
 32 

 (d) Participations. By the issuance of a Letter of Credit (or an amendment to a
Letter of Credit increasing the amount thereof) and without any further action on the part of the Issuing Bank or the Lenders, the Issuing Bank hereby grants to each Lender, and each Lender hereby acquires from the Issuing Bank, a participation in
such Letter of Credit equal to such Lender’s Applicable Percentage of the aggregate amount available to be drawn under such Letter of Credit. In consideration and in furtherance of the foregoing, each Lender hereby absolutely and
unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided
in Section 2.08(e), or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.08(d) in respect of
Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default, the existence of a
Borrowing Base Deficiency or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever. 

(e) Reimbursement. If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall
reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 12:00 noon, Houston, Texas time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of
such LC Disbursement prior to 10:00 a.m., Houston, Texas time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 12:00 noon, Houston, Texas time, on (i) the Business Day
that the Borrower receives such notice, if such notice is received prior to 10:00 a.m., Houston, Texas time, on the day of receipt, or (ii) the Business Day immediately following the day that the Borrower receives such notice, if such notice is
not received prior to such time on the day of receipt; provided that if such LC Disbursement is not less than $1,000,000, the Borrower shall, subject to the conditions to Borrowing set forth herein, be deemed to have requested, and the Borrower does
hereby request under such circumstances, that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the
resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s
Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with
respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the
Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.08(e), the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have
made payments pursuant to this Section 2.08(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.08(e) to reimburse the Issuing
Bank for any LC Disbursement (other than the funding of ABR Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement. 

  
 33 

 (f) Obligations Absolute. The Borrower’s obligation to reimburse LC
Disbursements as provided in Section 2.08(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of
(i) any lack of validity or enforceability of any Letter of Credit, any Letter of Credit Agreement or this Agreement, or any term or provision therein, (ii) any draft or other document presented under a Letter of Credit proving to be
forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply
with the terms of such Letter of Credit or any Letter of Credit Agreement, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section 2.08(f),
constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties shall have any
liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding
sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any
error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of
any direct damages (as opposed to consequential damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise
care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing
Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised all requisite care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the
parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents
without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of
Credit. 
 (g) Disbursement Procedures. The Issuing Bank shall, promptly following its receipt thereof, examine all
documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing
Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC
Disbursement. 
 (h) Interim Interest. If the Issuing Bank shall make any LC Disbursement, then, until the Borrower shall
have reimbursed the Issuing Bank for such LC Disbursement (either with its own funds or a Borrowing under Section 2.08(e)), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to

  
 34 

 
but excluding the date that the Borrower reimburses such LC Disbursement, at the rate per annum then applicable to ABR Loans. Interest accrued pursuant to this Section 2.08(h) shall be for
the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.08(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

 (i) Replacement of the Issuing Bank. The Issuing Bank may be replaced at any time by written agreement among the
Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank. The Administrative Agent shall notify the Lenders of any such replacement of the Issuing Bank. At the time any such replacement shall become effective, the
Borrower shall pay all unpaid fees accrued for the account of the replaced Issuing Bank pursuant to Section 3.05(b). From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing
Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of the Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and
obligations of the Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit. 

(j) Cash Collateralization. If (i) any Event of Default shall occur and be continuing and the Borrower receives notice from
the Administrative Agent or the Majority Lenders demanding the deposit of cash collateral pursuant to this Section 2.08(j), or (ii) the Borrower is required to pay to the Administrative Agent the excess attributable to an LC Exposure in
connection with any prepayment pursuant to Section 3.04(c), then the Borrower shall deposit, in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to, in
the case of an Event of Default, the LC Exposure, and in the case of a payment required by Section 3.04(c), the amount of such excess as provided in Section 3.04(c), as of such date plus any accrued and unpaid interest thereon; provided
that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default with respect
to the Parent Guarantor, the Borrower or any Subsidiary described in Section 10.01(h) or Section 10.01(i). The Borrower hereby grants to the Administrative Agent, for the benefit of the Issuing Bank and the Lenders, an exclusive first
priority and continuing perfected security interest in and Lien on such account and all cash, checks, drafts, certificates and instruments, if any, from time to time deposited or held in such account, all deposits or wire transfers made thereto, any
and all investments purchased with funds deposited in such account, all interest, dividends, cash, instruments, financial assets and other Property from time to time received, receivable or otherwise payable in respect of, or in exchange for, any or
all of the foregoing, and all proceeds, products, accessions, rents, profits, income and benefits therefrom, and any substitutions and replacements therefor. The Borrower’s obligation to deposit amounts pursuant to this Section 2.08(j)
shall be absolute and unconditional, without regard to whether any beneficiary of any such Letter of Credit has attempted to draw down all or a portion of such amount under the terms of a Letter of Credit, and, to the fullest extent permitted by
applicable law, shall not be subject to any defense or be affected by a right of set-off, counterclaim or recoupment which the Parent 

  
 35 

 
Guarantor, the Borrower or any of their Subsidiaries may now or hereafter have against any such beneficiary, the Issuing Bank, the Administrative Agent, the Lenders or any other Person for any
reason whatsoever. Such deposit shall be held as collateral securing the payment and performance of the obligations of the Parent Guarantor, the Borrower and the other Guarantors under this Agreement and the other Loan Documents. The Administrative
Agent shall have exclusive dominion and control, including the exclusive right of withdrawal, over such account. Other than any interest earned on the investment of such deposits, which investments, if any, shall be made at the option and sole
discretion of the Administrative Agent, but subject to the consent (not to be unreasonably withheld) of the Borrower and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments
shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the
satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated, be applied to satisfy other obligations of the Parent Guarantor, the Borrower and any Subsidiary
under this Agreement or the other Loan Documents. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, and the Borrower is not otherwise required to pay to the
Administrative Agent the excess attributable to an LC Exposure in connection with any prepayment pursuant to Section 3.04(c), then such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three Business Days
after all Events of Default have been cured or waived. 
 Section 2.09 Cash Collateral. 

(a) At any time that there shall exist a Defaulting Lender, within one Business Day following the written request of the Administrative
Agent or the Issuing Bank (with a copy to the Administrative Agent), the Borrower shall Cash Collateralize the Fronting Exposure of the Issuing Bank with respect to such Defaulting Lender (determined after giving effect to Section 2.10(a)(iv)
and any Cash Collateral provided by such Defaulting Lender) in an amount not less than the Minimum Collateral Amount. The Borrower may use proceeds of Borrowings for the provision of Cash Collateral (so long as no Borrowing Base Deficiency, Default
or Event of Default exists). 
 (i) Grant of Security Interest. The Borrower, and to the extent provided by any
Defaulting Lender, such Defaulting Lender, hereby grants to the Administrative Agent, for the benefit of the Issuing Bank, and agrees to maintain, a first priority security interest in all such Cash Collateral as security for the Defaulting
Lender’s obligation to fund participations in respect of LC Exposure, to be applied pursuant to subsection (ii) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person
other than the Administrative Agent and the Issuing Bank as herein provided, or that the total amount of such Cash Collateral is less than the Minimum Collateral Amount, the Borrower will, within 2 Business Days upon demand by the Administrative
Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by the Defaulting Lender). 

  
 36 

 (ii) Application. Notwithstanding anything to the contrary contained in this
Agreement, Cash Collateral provided under this Section 2.09 or Section 2.10 in respect of Letters of Credit shall be applied to the satisfaction of the Defaulting Lender’s obligation to fund participations in respect of LC Exposure
(including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

 (iii) Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce the
Fronting Exposure of the Issuing Bank shall no longer be required to be held as Cash Collateral pursuant to this Section 2.09 following (i) the elimination of the applicable Fronting Exposure (including by the termination of Defaulting
Lender status of the applicable Lender), or (ii) the determination by the Administrative Agent and the Issuing Bank that there exists excess Cash Collateral; provided that, subject to Section 2.10, the Person providing Cash Collateral and
the Issuing Bank may agree that Cash Collateral shall be held to support future anticipated Fronting Exposure or other obligations; and provided further that to the extent that such Cash Collateral was provided by the Borrower, such Cash Collateral
shall remain subject to the security interest granted pursuant to the Loan Documents. 
 Section 2.10 Defaulting
Lenders. 
 (a) Defaulting Lender Adjustments. Notwithstanding anything to the contrary contained in this Agreement,
if any Lender becomes a Defaulting Lender, then, until such time as such Lender is no longer a Defaulting Lender, to the extent permitted by Applicable Law: 
 (i) Waivers and Amendments. Such Defaulting Lender’s right to approve or disapprove any amendment, waiver or consent with respect to this Agreement shall be restricted as set forth in the
definition of Majority Lenders. 
 (ii) Defaulting Lender Waterfall. Any payment of principal, interest, fees or other
amounts received by the Administrative Agent for the account of such Defaulting Lender (whether voluntary or mandatory, at maturity, pursuant to Article X or otherwise) or received by the Administrative Agent from a Defaulting Lender pursuant to
Section 12.08 shall be applied at such time or times as may be determined by the Administrative Agent as follows: first, to the payment of any amounts owing by such Defaulting Lender to the Administrative Agent hereunder; second, to the payment
on a pro rata basis of any amounts owing by such Defaulting Lender to the Issuing Bank hereunder; third, to Cash Collateralize the Fronting Exposure of the Issuing Bank with respect to such Defaulting Lender in accordance with Section 2.09;
fourth, as the Borrower may request (so long as no Default or Event of Default exists), to the funding of any Loan or funded participation in respect of which such Defaulting Lender has failed to fund its portion thereof as required by this
Agreement, as determined by the Administrative Agent; fifth, if so determined by the Administrative Agent and the Borrower, to be held in a deposit account and released pro rata in order to (A) satisfy such Defaulting Lender’s potential
future funding obligations with respect to Loans and funded participations under this Agreement and (B) Cash Collateralize the Issuing Bank’s future Fronting Exposure with respect to such Defaulting Lender with respect to future Letters of
Credit issued under this Agreement, in accordance with Section 2.09; sixth, to the payment of any amounts owing to the 

  
 37 

 
Lenders or the Issuing Bank as a result of any judgment of a court of competent jurisdiction obtained by any Lender or the Issuing Bank against such Defaulting Lender as a result of such
Defaulting Lender’s breach of its obligations under this Agreement; seventh, so long as no Default or Event of Default exists, to the payment of any amounts owing to the Borrower as a result of any judgment of a court of competent jurisdiction
obtained by the Borrower against such Defaulting Lender as a result of such Defaulting Lender’s breach of its obligations under this Agreement; and eighth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction;
provided that if (1) such payment is a payment of the principal amount of any Loans or funded participations in Letters of Credit in respect of which such Defaulting Lender has not fully funded its appropriate share, and (2) such Loans
were made or the related Letters of Credit were issued at a time when the conditions set forth in Section 6.02 were satisfied or waived, such payment shall be applied solely to pay the Loans of, and funded participations in Letters of Credit
owed to, all Non-Defaulting Lenders on a pro rata basis prior to being applied to the payment of any Loans of, or funded participations in Letters of Credit owed to, such Defaulting Lender until such time as all Loans and funded and unfunded
participations in LC Exposure are held by the Lenders pro rata in accordance with the Commitment under the Agreement without giving effect to Section 2.10(a)(iv). Any payments, prepayments or other amounts paid or payable to a Defaulting Lender
that are applied (or held) to pay amounts owed by a Defaulting Lender or to post Cash Collateral pursuant to this Section 2.10(a)(ii) shall be deemed paid to and redirected by such Defaulting Lender, and each Lender irrevocably consents hereto.

 (iii) Certain Fees. 
 (A) No Defaulting Lender shall be entitled to receive any commitment fee for any period during which that Lender is a Defaulting Lender (and the Borrower shall not be required to pay any such fee that
otherwise would have been required to have been paid to that Defaulting Lender). 
 (B) Each Defaulting Lender shall be
entitled to receive letter of credit fees pursuant to Section 3.05(b) for any period during which that Lender is a Defaulting Lender only to the extent allocable to its Applicable Percentage of the stated amount of Letters of Credit for which
it has provided Cash Collateral pursuant to Section 2.09. 
 (C) With respect to any commitment fee or letter of credit
fee not required to be paid to any Defaulting Lender pursuant to clause (A) or (B) above, the Borrower shall (1) pay to each Non-Defaulting Lender that portion of any such fee otherwise payable to such Defaulting Lender with respect
to such Defaulting Lender’s participation in LC Exposure that has been reallocated to such Non-Defaulting Lender pursuant to clause (iv) below, (2) pay to each Issuing Bank, as applicable, the amount of any such fee otherwise payable
to such Defaulting Lender to the extent allocable to such Issuing Bank’s Fronting Exposure to such Defaulting Lender, and (3) not be required to pay the remaining amount of any such fee. 

(iv) Reallocation of Participations to Reduce Fronting Exposure. All or any part of such Defaulting Lender’s participation
in LC Exposure shall be reallocated among the Non-Defaulting Lenders in accordance with their respective Applicable Percentages (calculated without regard to such Defaulting Lender’s Commitment) but only to the extent that

  
 38 

 
(x) the conditions set forth in Section 6.2 are satisfied at the time of such reallocation (and, unless the Borrower shall have otherwise notified the Administrative Agent at such time, the
Borrower shall be deemed to have represented and warranted that such conditions are satisfied at such time), and (y) such reallocation does not cause the aggregate Revolving Credit Exposure of any Non-Defaulting Lender to exceed such
Non-Defaulting Lender’s Applicable Percentage of the Commitment. No reallocation hereunder shall constitute a waiver or release of any claim of any party hereunder against a Defaulting Lender arising from that Lender having become a Defaulting
Lender, including any claim of a Non-Defaulting Lender as a result of such Non-Defaulting Lender’s increased exposure following such reallocation. 
 (v) Cash Collateral. If the reallocation described in clause (iv) above cannot, or can only partially, be effected, the Borrower shall, without prejudice to any right or remedy available to it
hereunder or under law, Cash Collateralize the Issuing Bank’s Fronting Exposure in accordance with the procedures set forth in Section 2.09. 
 (b) Defaulting Lender Cure. If the Borrower, the Administrative Agent and the Issuing Bank agree in writing that a Lender is no longer a Defaulting Lender, the Administrative Agent will so notify
the parties hereto, whereupon as of the effective date specified in such notice and subject to any conditions set forth therein (which may include arrangements with respect to any Cash Collateral), such Lender will, to the extent applicable,
purchase at par that portion of outstanding Loans of the other Lenders or take such other actions as the Administrative Agent may determine to be necessary to cause the Loans and funded and unfunded participations in Letters of Credit to be held pro
rata by the Lenders in accordance with the Commitments under this Agreement (without giving effect to Section 2.10(a)(iv)), whereupon such Lender will cease to be a Defaulting Lender; provided that no adjustments will be made retroactively with
respect to fees accrued or payments made by or on behalf of the Borrower while that Lender was a Defaulting Lender; and provided, further, that except to the extent otherwise expressly agreed by the affected parties, no change hereunder from
Defaulting Lender to Lender will constitute a waiver or release of any claim of any party hereunder arising from that Lender’s having been a Defaulting Lender. 
 (c) New Letters of Credit. So long as any Lender is a Defaulting Lender, no Issuing Bank shall be required to issue, extend, renew or increase any Letter of Credit unless it is satisfied that it
will have no Fronting Exposure after giving effect thereto. 
 ARTICLE III 

Payments of Principal and Interest; Prepayments; Fees 
 Section 3.01 Repayment of Loans. The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan on
the Termination Date. 
 Section 3.02 Interest. 

(a) ABR Loans. The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Margin,
but in no event to exceed the Highest Lawful Rate. 

  
 39 

 (b) Eurodollar Loans. The Loans comprising each Eurodollar Borrowing shall bear
interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Margin, but in no event to exceed the Highest Lawful Rate. 
 (c) Post-Default Rate and Borrowing Base Deficiency Rate. Notwithstanding the foregoing, (i) if an Event of Default has occurred and is continuing, or if any principal of or interest on any
Loan or any fee or other amount payable by the Parent Guarantor, the Borrower or any other Guarantor hereunder or under any other Loan Document is not paid when due, whether at stated maturity, upon acceleration or otherwise, and including any
payments in respect of a Borrowing Base Deficiency under Section 3.04(c), then all Loans outstanding, in the case of an Event of Default, and such overdue amount, in the case of a failure to pay amounts when due, shall bear interest, after as
well as before judgment, at a rate per annum equal to two percent (2%) plus the rate applicable to ABR Loans as provided in Section 3.02(a), but in no event to exceed the Highest Lawful Rate, and (ii) during any Borrowing Base
Deficiency, all Loans outstanding at such time shall bear interest, after as well as before judgment, at the rate then applicable to such Loans, plus the Applicable Margin, if any, plus an additional two percent (2%), but in no event to exceed the
Highest Lawful Rate. 
 (d) Interest Payment Dates. Accrued interest on each Loan shall be payable in arrears on each
Interest Payment Date for such Loan and on the Termination Date; provided that (i) interest accrued pursuant to Section 3.02(c) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than an
optional prepayment of an ABR Loan prior to the Termination Date), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment, and (iii) in the event of any conversion of any
Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion. 
 (e) Interest Rate Computations. All interest hereunder shall be computed on the basis of a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest
shall be computed on the basis of a year of 365 days (or 366 days in a leap year), except that interest computed by reference to the Alternate Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall be computed on the basis
of a year of 365 days (or 366 days in a leap year), and in each case shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable Alternate Base Rate or Adjusted LIBO Rate shall be
determined by the Administrative Agent, and such determination shall be conclusive absent manifest error, and be binding upon the parties hereto. 
 Section 3.03 Alternate Rate of Interest. If prior to the commencement of any Interest Period for a Eurodollar Borrowing: 

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable
means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or 
 (b) the
Administrative Agent is advised by the Majority Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included
in such Borrowing for such Interest Period; 

  
 40 

 then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by
telephone or telecopy as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that
requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective, and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing.

 Section 3.04 Prepayments. 
 (a) Optional Prepayments. The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part, subject to prior notice in accordance with
Section 3.04(b). 
 (b) Notice and Terms of Optional Prepayment. The Borrower shall notify the Administrative Agent
by telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of prepayment of a Eurodollar Borrowing, not later than 12:00 noon, Houston, Texas time, three Business Days before the date of prepayment, or (ii) in the
case of prepayment of an ABR Borrowing, not later than 12:00 noon, Houston, Texas time, one Business Day before the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date and the principal amount of each
Borrowing or portion thereof to be prepaid. Promptly following receipt of any such notice relating to a Borrowing, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an
amount that would be permitted in the case of an advance of a Borrowing of the same Type as provided in Section 2.02. Each prepayment of a Borrowing shall be applied ratably to the Loans included in the prepaid Borrowing. Prepayments shall be
accompanied by accrued interest to the extent required by Section 3.02. 
 (c) Mandatory Prepayments. 

(i) If, after giving effect to any termination or reduction of the Aggregate Maximum Credit Amounts pursuant to Section 2.06(b), the
total Revolving Credit Exposures exceeds the total Commitments, then the Borrower shall (A) prepay the Borrowings on the date of such termination or reduction in an aggregate principal amount equal to such excess, and (B) if any excess
remains after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). 

(ii) Upon any redetermination of or adjustment to the amount of the Borrowing Base in accordance with Section 2.07 (other than
Section 2.07(e) and Section 2.07(f)) or Section 8.13(c), if the total Revolving Credit Exposure exceeds the redetermined or adjusted Borrowing Base, then the Borrower shall (A) prepay the Borrowings in an aggregate principal
amount equal to such excess, and (B) if the Borrower prepays such Borrowings pursuant to clause (A) of this subsection and any excess remains after prepaying all of the Borrowings as a

  
 41 

 
result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower
shall be obligated to make such prepayment and/or deposit of cash collateral within ninety (90) days following its receipt of the New Borrowing Base Notice in accordance with Section 2.07(d) or the date the adjustment occurs (and may make
such prepayment and/or deposit at any time and from time to time, in whole or in part, prior to the end of such 90-day period); provided that all payments required to be made pursuant to this Section 3.04(c)(ii) must be made on or prior to the
Termination Date. 
 (iii) Upon any adjustments to the Borrowing Base pursuant to Section 2.07(e), Section 2.07(f) or
Section 9.12(d), if the total Revolving Credit Exposures exceeds the Borrowing Base as adjusted, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal to such excess, and (B) if any excess remains
after prepaying all of the Borrowings as a result of an LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to such excess to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be
obligated to make such prepayment and/or deposit of cash collateral on the date of such termination, creation of offsetting positions or it receives cash proceeds as a result of such issuance or disposition; provided that all payments required to be
made pursuant to this Section 3.04(c)(iii) must be made on or prior to the Termination Date. 
 (iv) Notwithstanding
anything to the contrary herein, if the Borrower or any of its Subsidiaries sells any Property when a Borrowing Base Deficiency or Event of Default exists, then the Borrower shall (A) prepay the Borrowings in an aggregate principal amount equal
to the net cash proceeds received from such sale, and (B) if any excess remains after prepaying all of the Borrowings and there exists any LC Exposure, pay to the Administrative Agent on behalf of the Lenders an amount equal to the lesser of
such excess and the amount of such LC Exposure to be held as cash collateral as provided in Section 2.08(j). The Borrower shall be obligated to make such prepayment and/or deposit of cash collateral on the date it or any Subsidiary receives
cash proceeds as a result of such sale; provided that all payments required to be made pursuant to this Section 3.04(c)(iv) must be made on or prior to the Termination Date. 

(v) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied, first, ratably to any ABR Borrowings then
outstanding, and, second, to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least
number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto. 

(vi) Each prepayment of Borrowings pursuant to this Section 3.04(c) shall be applied ratably to the Loans included in the prepaid
Borrowings. Prepayments pursuant to this Section 3.04(c) shall be accompanied by accrued interest to the extent required by Section 3.02. 
 (d) No Premium or Penalty. Prepayments permitted or required under this Section 3.04 shall be without premium or penalty, except as required under Section 5.02.

 Section 3.05 Fees. 

(a) Commitment Fees. The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which
shall accrue at a rate per annum of 0.50% on the average daily amount of the unused amount of the Commitment of such Lender during the period from and including the date of this Agreement to but excluding the Termination Date. Accrued commitment
fees shall be payable in arrears on the last day of March, June, September and December of each year and on the Termination Date, commencing on the first such date to occur after the date hereof. All commitment fees shall be computed on the basis of
a year of 360 days, unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed
(including the first day but excluding the last day). 
 (b) Letter of Credit Fees. The Borrower agrees to pay
(i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Margin used to determine the interest rate applicable to
Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later
of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure, (ii) to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.25% per annum on the average daily
amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the date of this Agreement to but excluding the later of the date of termination of the Commitments and the
date on which there ceases to be any LC Exposure, provided that in no event shall such fee be less than $500 during any calendar year, and (iii) to the Issuing Bank, for its own account, its standard fees with respect to the issuance,
amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees accrued through and including the last day of March, June, September and December of each year shall be payable on the
third Business Day following such last day, commencing on the first such date to occur after the date of this Agreement; provided that all such fees shall be payable on the Termination Date and any such fees accruing after the Termination Date shall
be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 3.05(b) shall be payable within 10 days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days,
unless such computation would exceed the Highest Lawful Rate, in which case interest shall be computed on the basis of a year of 365 days (or 366 days in a leap year), and shall be payable for the actual number of days elapsed (including the first
day but excluding the last day). 
 (c) Other Fees. The Borrower agrees to pay to the Administrative Agent, for its own
account and for the account of each Lender, as applicable, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent in the Fee Letter.

 ARTICLE IV 
 Payments; Pro Rata Treatment; Sharing of Set-offs 
 Section 4.01
Payments Generally; Pro Rata Treatment; Sharing of Set-offs. 
 (a) Payments by the Borrower. The Borrower shall
make each payment required to be made by it hereunder (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 5.01, Section 5.02, Section 5.03 or otherwise) prior to 12:00 noon,
Houston, Texas time, on the date when due, in immediately available funds, without defense, deduction, recoupment, set-off or counterclaim. Fees, once paid, shall be fully earned and shall not be refundable under any circumstances. Any amounts
received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the
Administrative Agent at its offices specified in Section 12.01, except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Section 5.01, Section 5.02, Section 5.03
and Section 12.03 shall be made directly to the Persons entitled thereto. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt
thereof. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of any payment accruing interest, interest thereon shall be payable for
the period of such extension. All payments hereunder shall be made in dollars. 
 (b) Application of Insufficient
Payments. If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees then due hereunder, such funds shall be applied
(i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and
unreimbursed LC Disbursements then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements then due to such parties. 

(c) Sharing of Payments by Lenders. If any Lender shall, by exercising any right of set-off or counterclaim or otherwise, obtain
payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC
Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements
of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC
Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such
recovery, without interest, and (ii) the provisions of this Section 4.01(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this

  
 44 

 
Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or
participant, other than to the Parent Guarantor, the Borrower or any Subsidiary or Affiliate thereof (as to which the provisions of this Section 4.01(c) shall apply). The Parent Guarantor and the Borrower consent to the foregoing and agree, to
the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Parent Guarantor or the Borrower rights of set-off and counterclaim with respect to
such participation as fully as if such Lender were a direct creditor of the Parent Guarantor or the Borrower in the amount of such participation. 
 Section 4.02 Presumption of Payment by the Borrower. Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the
Administrative Agent for the account of the Lenders or the Issuing Bank that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in
reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. In such event, if the Borrower has not in fact made such payment, then each of the Lenders or the Issuing Bank, as the case may be,
severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the
date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation. 

Section 4.03 Disposition of Proceeds. The Security Instruments contain an assignment by the Parent Guarantor, the Borrower
and/or the other Guarantors unto and in favor of the Administrative Agent for the benefit of the Lenders of all of the Borrower’s and/or each Guarantor’s interest in and to production and all proceeds attributable thereto which may be
produced from or allocated to the Mortgaged Property. The Security Instruments further provide in general for the application of such proceeds to the satisfaction of the Indebtedness and other obligations described therein and secured thereby.
Notwithstanding the assignment contained in such Security Instruments, until the occurrence of an Event of Default, (a) the Administrative Agent and the Lenders agree that they will neither notify the purchaser or purchasers of such production
nor take any other action to cause such proceeds to be remitted to the Administrative Agent or the Lenders, but the Lenders will instead permit such proceeds to be paid to the Parent Guarantor, the Borrower and their Subsidiaries and (b) the
Lenders hereby authorize the Administrative Agent to take such actions as may be necessary to cause such proceeds to be paid to the Parent Guarantor, the Borrower and such Subsidiaries. 

ARTICLE V 

Increased Costs; Break Funding Payments; Taxes; Illegality 
 Section 5.01 Increased Costs. 
 (a) Eurodollar Changes in Law.
If any Change in Law shall: 
 (i) impose, modify or deem applicable any reserve, special deposit or similar requirement
against assets of, deposits with or for the account of, or credit extended by, any Lender (except any such reserve requirement reflected in the Adjusted LIBO Rate); or 

  
 45 

 (ii) impose on any Lender or the London interbank market any other condition affecting this
Agreement or Eurodollar Loans made by such Lender; 
 and the result of any of the foregoing shall be to increase the cost to such Lender of
making or maintaining any Eurodollar Loan (or of maintaining its obligation to make any such Loan) or to reduce the amount of any sum received or receivable by such Lender (whether of principal, interest or otherwise), then the Borrower will pay to
such Lender such additional amount or amounts as will compensate such Lender for such additional costs incurred or reduction suffered. 
 (b) Capital Requirements. If any Lender or the Issuing Bank determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such
Lender’s or the Issuing Bank’s capital or on the capital of such Lender’s or the Issuing Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by, or participations in Letters of Credit held by,
such Lender, or the Letters of Credit issued by the Issuing Bank, to a level below that which such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company could have achieved but for such Change in Law (taking
into consideration such Lender’s or the Issuing Bank’s policies and the policies of such Lender’s or the Issuing Bank’s holding company with respect to capital adequacy), then from time to time the Borrower will pay to such
Lender or the Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or the Issuing Bank or such Lender’s or the Issuing Bank’s holding company for any such reduction suffered. 

(c) Certificates. A certificate of a Lender or the Issuing Bank setting forth the amount or amounts necessary to compensate such
Lender or the Issuing Bank or its holding company, as the case may be, as specified in Section 5.01(a) or (b) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or the
Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof. 
 (d)
Effect of Failure or Delay in Requesting Compensation. Failure or delay on the part of any Lender or the Issuing Bank to demand compensation pursuant to this Section 5.01 shall not constitute a waiver of such Lender’s or the Issuing
Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or the Issuing Bank pursuant to this Section 5.01 for any increased costs or reductions incurred more than 365 days prior to
the date that such Lender or the Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or the Issuing Bank’s intention to claim compensation
therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 365-day period referred to above shall be extended to include the period of retroactive effect thereof. 

Section 5.02 Break Funding Payments. In the event of (a) the payment of any principal of any Eurodollar Loan other than
on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an 

  
 46 

 
ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice
delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto pursuant to Section 5.04, then, in any such event, the Borrower shall compensate each Lender for
the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any, of (i) the amount of
interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then
current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount
for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the Eurodollar market. 

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this
Section 5.02 shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof. 

Section 5.03 Taxes. 
 (a) Payments Free of Taxes. Any and all payments by or on account of any obligation of the Parent Guarantor, the Borrower or any Guarantor under any Loan Document shall be made free and clear of
and without deduction for any Indemnified Taxes or Other Taxes; provided that if the Borrower or any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as
necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 5.03(a)), the Administrative Agent, Lender or Issuing Bank (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 or such Guarantor shall make such deductions and (iii) the Borrower or such Guarantor shall pay the full amount deducted to the relevant Governmental
Authority in accordance with applicable law. 
 (b) Payment of Other Taxes by the Borrower. The Borrower shall pay any
Other Taxes to the relevant Governmental Authority in accordance with applicable law. 
 (c) Indemnification by the
Borrower. The Borrower shall indemnify the Administrative Agent, each Lender and the Issuing Bank, within 10 days after written demand therefor, for the full amount of any Indemnified Taxes or Other Taxes paid by the Administrative Agent, such
Lender or the Issuing Bank, 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 5.03) 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 of the Administrative Agent, a Lender or the Issuing Bank as to the amount of such payment or liability under this Section 5.03 shall be delivered to the Borrower and shall be conclusive absent manifest
error. 

  
 47 

 (d) Evidence of Payments. As soon as practicable after any payment of Indemnified
Taxes or Other Taxes by the Borrower or a Guarantor to a Governmental Authority, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a
copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent. 
 (e) Foreign Lenders. Any Foreign Lender that is entitled to an exemption from or reduction of withholding tax under the law of the jurisdiction in which the Borrower is located, or any treaty to
which such jurisdiction is a party, with respect to payments under this Agreement or any other Loan Document shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or times prescribed by applicable law, such properly
completed and executed documentation prescribed by applicable law or reasonably requested by the Borrower as will permit such payments to be made without withholding or at a reduced rate. In addition, any Lender, if requested by the Borrower or the
Administrative Agent, shall deliver such other documentation prescribed by Applicable Law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such
Lender is subject to backup withholding or information reporting requirements. Without limiting the generality of the foregoing, in the event that the Borrower is a resident for tax purposes in the United States, any Foreign Lender shall deliver to
the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the request
of the Borrower or the Administrative Agent, but only if such Foreign Lender is legally entitled to do so), whichever of the following is applicable: 
 (i) duly completed copies of IRS Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party; 

(ii) duly completed copies of IRS Form W-8ECI; 
 (iii) 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 such Foreign Lender is not
(A) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (B) a “10 percent shareholder” of the Borrower within the meaning of section 881(c)(3)(B) of the Code, or (C) a “controlled foreign
corporation” described in section 881(c)(3)(C) of the Code and (y) duly completed copies of IRS Form W-8BEN; or 

(iv) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in United States Federal
withholding tax duly completed together with such supplementary documentation as may be prescribed by Applicable Law to permit the Borrower to determine the withholding or deduction required to be made. 

  
 48 

 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 fails to comply with any requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall (A) enter into such agreements with the
IRS as necessary to establish an exemption from withholding under FATCA; (B) comply with any certification, documentation, information, reporting or other requirement necessary to establish an exemption from withholding under FATCA;
(C) provide any documentation reasonably requested by the Borrower or the Administrative Agent sufficient for the Administrative Agent and the Borrower to comply with their respective obligations, if any, under FATCA and to determine that such
Lender has complied such applicable requirements; and (D) provide a certification signed by the chief financial officer, principal accounting officer, treasurer or controller of such Lender certifying that such Lender has complied with any
necessary requirements to establish an exemption from withholding under FATCA. To the extent that the relevant documentation provided pursuant to this paragraph is rendered obsolete or inaccurate in any material respect as a result of changes in
circumstances with respect to the status of a Lender or Issuing Bank, such Lender or Issuing Bank shall, to the extent permitted by Applicable Law, deliver to the Borrower and the Administrative Agent revised and/or updated documentation sufficient
for the Borrower and the Administrative Agent to confirm such Lender’s or such Issuing Bank’s compliance with their respective obligations under FATCA. 
 Section 5.04 Mitigation Obligations. If any Lender requests compensation under Section 5.01, or if the Borrower is required to pay any additional amount to any Lender or any Governmental
Authority for the account of any Lender pursuant to Section 5.03, then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder
to another of its offices, branches or affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 5.01 or Section 5.03, as the case may be, in the
future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in
connection with any such designation or assignment. 
 Section 5.05 Illegality. Notwithstanding any other provision
of this Agreement, in the event that it becomes unlawful for any Lender or its applicable lending office to honor its obligation to make or maintain Eurodollar Loans either generally or having a particular Interest Period hereunder, then
(a) such Lender shall promptly notify the Borrower and the Administrative Agent thereof and such Lender’s obligation to make such Eurodollar Loans shall be suspended (the “Affected Loans”) until such time as such Lender
may again make and maintain such Eurodollar Loans and (b) all Affected Loans which would otherwise be made by such Lender shall be made instead as ABR Loans (and, if such Lender so requests by notice to the Borrower and the Administrative
Agent, all Affected Loans of such Lender then outstanding shall be automatically converted into ABR Loans on the date specified by such Lender in such notice) and, to the extent that Affected Loans are so made as (or converted into) ABR Loans, all
payments of principal which would otherwise be applied to such Lender’s Affected Loans shall be applied instead to its ABR Loans.

ARTICLE VII 

Representations and Warranties 
 The Parent Guarantor and the Borrower each represents and warrants to the Lenders that: 
 Section 7.01 Organization; Powers. Each of the Parent Guarantor, the Borrower and their Subsidiaries is duly organized, validly existing and in good standing under the laws of the jurisdiction
of its organization, has all requisite power and authority, and has all material governmental licenses, authorizations, consents and approvals necessary, to own its assets and to carry on its business as now conducted, and is qualified to do
business in, and is in good standing in, every jurisdiction where such qualification is required, except where failure to have such power, authority, licenses, authorizations, consents, approvals and qualifications could not reasonably be expected
to have a Material Adverse Effect. 
 Section 7.02 Authority; Enforceability. The Transactions are within the Parent
Guarantor’s, the Borrower’s and each other Guarantor’s corporate, partnership or other organizational powers and have been duly authorized by all necessary organizational action and, if required, action by any holders of its Equity
Interests. Each Loan Document to which the Parent Guarantor, the Borrower and each other Guarantor is a party has been duly executed and delivered by the Parent Guarantor, the Borrower and such other Guarantor and constitutes a legal, valid and
binding obligation of the Parent Guarantor, the Borrower and such other Guarantor, as applicable, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 
 Section 7.03 Approvals; No Conflicts. The Transactions (a) do not require any consent or approval of, registration or filing with, or any other action by, any Governmental Authority or
any other third Person (including holders of its Equity Interests or any class of directors, managers or supervisors, as applicable, whether interested or disinterested, of the Parent Guarantor, the Borrower or any other Person), nor is any such

and which has not been set forth in this Agreement or the Loan Documents or the other documents, certificates and statements furnished to the Administrative Agent or the Lenders by or on behalf of the Borrower or any Subsidiary prior to, or on, the
date hereof in connection with the transactions contemplated hereby. There are no statements or conclusions in any Reserve 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 projections concerning volumes attributable to the Oil and Gas Properties of the Parent Guarantor, the Borrower and their Subsidiaries and production and cost estimates contained in each Reserve

The Administrative Agent and the Lenders have been named as additional insureds in respect of such liability insurance policies and the Administrative Agent has been named as loss payee with respect to Property loss insurance. 

Section 7.13 Restriction on Liens. Neither the Parent Guarantor, the Borrower nor any of their Subsidiaries are a party to

personal Properties, in each case, free and clear of all Liens except Liens permitted by Section 9.03. After giving full effect to the Excepted Liens, the Parent Guarantor, the Borrower or the Subsidiary specified as the owner owns the net
interests in production attributable to the Hydrocarbon Interests as reflected in the most recently delivered Reserve Report, and the ownership of such Properties shall not in any material respect obligate the Parent Guarantor, the Borrower or such
Subsidiary to bear the costs and expenses relating to the maintenance, development and operations of each such Property in an amount in excess of the working interest of each Property set forth in the most recently delivered Reserve Report that is
not offset by a corresponding proportionate increase in the Parent Guarantor’s, the Borrower’s or such Subsidiary’s net revenue interest in such Property. 

  
 58 

 (b) All material leases and agreements necessary for the conduct of the business of the
Parent Guarantor, the Borrower and their Subsidiaries are valid and subsisting, in full force and effect, and there exists no default or event or circumstance which with the giving of notice or the passage of time or both would give rise to a
default under any such lease or leases, which could reasonably be expected to have a Material Adverse Effect. 
 (c) The rights
and Properties presently owned, leased or licensed by the Parent Guarantor, the Borrower and their Subsidiaries including, without limitation, all easements and rights of way, include all rights and Properties necessary to permit the Parent
Guarantor, the Borrower and their Subsidiaries to conduct their business in all material respects in the same manner as its business has been conducted prior to the date hereof. 

(d) All of the Properties of the Parent Guarantor, the Borrower and their Subsidiaries which are reasonably necessary for the operation

 (e) The
Parent Guarantor, the Borrower and their Subsidiaries own, or are licensed to use, all trademarks, tradenames, copyrights, patents and other intellectual Property material to its business, and the use thereof by the Parent Guarantor, the Borrower
and their Subsidiaries does not infringe upon the rights of any other Person, except for any such infringements that, individually or in the aggregate, could not reasonably be expected to result in a Material Adverse Effect. The Parent Guarantor,
the Borrower and their Subsidiaries either own or have valid licenses or other rights to use all databases, geological data, geophysical data, engineering data, seismic data, maps, interpretations and other technical information used in their
businesses as presently conducted, subject to the limitations contained in the agreements governing the use of the same, which limitations are customary for companies engaged in the business of the exploration and production of Hydrocarbons, with
such exceptions as could not reasonably be expected to have a Material Adverse Effect. 
 Section 7.17 Maintenance of
Properties. Except for such acts or failures to act as could not be reasonably expected to have a Material Adverse Effect, the Oil and Gas Properties (and Properties unitized therewith) of the Parent Guarantor, the Borrower and their
Subsidiaries have been maintained, operated and developed in a good and workmanlike manner and in conformity with all Governmental Requirements and in conformity with the provisions of all leases, subleases or other contracts comprising a part of
the Hydrocarbon Interests and other contracts and agreements forming a part of the Oil and Gas Properties of the Parent Guarantor, the Borrower and their Subsidiaries. Specifically in connection with the foregoing, except for those as could not be
reasonably expected to have a Material Adverse Effect, (i) no Oil and Gas Property of the Parent Guarantor, the Borrower or their Subsidiaries is subject to having allowable production reduced below the full and regular allowable (including the
maximum permissible tolerance) because of any overproduction (whether or not the same was permissible at the time) and (ii) none of the wells comprising a part of the Oil and Gas Properties (or Properties unitized therewith) of the Parent
Guarantor, the Borrower or their Subsidiaries are deviated from the vertical more than the maximum permitted by Governmental Requirements, 

  
 59 

 
and such wells are, in fact, bottomed under and are producing from, and the well bores are wholly within, the Oil and Gas Properties (or in the case of wells located on Properties unitized
therewith, such unitized Properties) of the Parent Guarantor, the Borrower or such Subsidiary. All pipelines, wells, gas processing plants, platforms and other material improvements, fixtures and equipment owned in whole or in part by the Parent
Guarantor, the Borrower or any of their Subsidiaries that are necessary to conduct normal operations are being maintained in a state adequate to conduct normal operations, and with respect to such of the foregoing which are operated by the Parent
Guarantor, the Borrower or any of their Subsidiaries, in a manner consistent with the Parent Guarantor’s, the Borrower’s or their Subsidiaries’ past practices (other than those the failure of which to maintain in accordance with this
Section 7.17 could not reasonably be expected to have a Material Adverse Effect). 
 Section 7.18 Gas Imbalances,
Prepayments. Except as set forth on the most recent certificate delivered pursuant to Section 8.12(c), on a net basis there are no gas imbalances, take or pay or other prepayments which would require the Parent Guarantor, the Borrower or
any of their Subsidiaries to deliver Hydrocarbons produced from the Oil and Gas Properties at some future time without then or thereafter receiving full payment therefor exceeding 500,000 Mcf of gas (on an mcf equivalent basis) in the aggregate.

not cancelable on 60 days notice or less without penalty or detriment for the sale of production from the Parent Guarantor’s, the Borrower’s or their Subsidiaries’ Hydrocarbons (including, without limitation, calls on or other rights
to purchase, production, whether or not the same are currently being exercised) that (a) pertain to the sale of production at a fixed price and (b) have a maturity or expiry date of longer than six (6) months from the date hereof.

and the Borrower pursuant to Section 8.01(d), sets forth, a true and complete list of all Swap Agreements of the Parent Guarantor, the Borrower and each Subsidiary not listed on Schedule 7.20, the material terms thereof (including the type,
term, effective date, termination date and notional amounts or volumes), the net mark to market value thereof, all credit support agreements relating thereto (including any margin required or supplied) and the counterparty to each such agreement.

 Section 7.21 Use of Loans and Letters of Credit. The proceeds of the Loans and the Letters of Credit shall be
used (a) to provide working capital for lease acquisitions, exploration, production operations and development (including the drilling and completion of producing wells) and (b) for general corporate purposes of the Borrower and the
Guarantors. The Borrower and its Subsidiaries are not engaged principally, or as one of its or their important activities, in the business of extending credit for the purpose, whether immediate, incidental or ultimate, of buying or carrying margin
stock (within the meaning of Regulation T, U or X of the Board). No part of the proceeds of any Loan or Letter of Credit will be used for any purpose which violates the provisions of Regulations T, U or X of the Board.

hereby, (a) the aggregate assets (after giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement), at a fair valuation, of the Parent Guarantor, the Borrower and their
Subsidiaries, taken as a whole, will exceed the aggregate Debt of the Parent Guarantor, the Borrower and their Subsidiaries, taken as a whole, as the Debt becomes absolute and matures, (b) the Parent Guarantor and the Borrower will not have
incurred or intended to incur, and will not believe that it will incur, Debt beyond its ability to pay such Debt (after taking into account the timing and amounts of cash to be received by it and the amounts to be payable on or in respect of its
liabilities, and giving effect to amounts that could reasonably be received by reason of indemnity, offset, insurance or any similar arrangement) as such Debt becomes absolute and matures and (c) the Parent Guarantor and the Borrower will not
have (and will have no reason to believe that it will have thereafter) unreasonably small capital for the conduct of its business.

Agent as soon as possible, but in any event no later than thirty (30) days following the receipt of such request. 
 (c)
With the delivery of each Reserve Report, the Borrower shall provide to the Administrative Agent and the Lenders a certificate from a Responsible Officer certifying that in all material respects: (i) the information contained in the Reserve
Report and any other information delivered in connection therewith is true and correct, (ii) the Borrower or its Subsidiaries own good and defensible title to the Oil and Gas Properties evaluated in such Reserve Report and such Properties are
free of all Liens except for Liens permitted by Section 9.03, (iii) except as set forth on an exhibit to the certificate, on a net basis there are no gas imbalances, take or pay or other prepayments in excess of the volume specified in
Section 7.18 with respect to its Oil and Gas Properties evaluated in such Reserve Report which would require the Borrower or any of its Subsidiaries to deliver Hydrocarbons either generally or produced from such Oil and Gas Properties at some
future time without then or thereafter receiving full payment therefor, (iv) none of their Oil and Gas Properties have been sold since the date of the last Borrowing Base determination except as set forth on an exhibit to the certificate, which
certificate shall list all of its Oil and Gas Properties sold and in such detail as reasonably required by the Administrative Agent, (v) attached to the certificate is a list of all marketing agreements entered into subsequent to the later of
the date hereof or the most recently delivered Reserve Report which the Borrower could reasonably be expected to have been obligated to list on Schedule 7.19 had such agreement been in effect on the date hereof and (vi) attached thereto is a
schedule of the Oil and Gas Properties evaluated by such Reserve Report that are Mortgaged Properties and demonstrating the percentage of the total value of the Oil and Gas Properties that the value of such Mortgaged Properties represent in

 Section 8.13 Title Information. 

(a) On or before the delivery to the Administrative Agent and the Lenders of each Reserve Report required by Section 8.12, the Parent
Guarantor and the Borrower will deliver title information in form and substance acceptable to the Administrative Agent covering enough of the Oil and Gas Properties evaluated by such Reserve Report that were not included in the immediately preceding
Reserve Report, so that the Administrative Agent shall have received together with title information previously delivered to the Administrative Agent, satisfactory title information on at least 80% of the total value of the Oil and Gas Properties
evaluated by such Reserve Report. 

  
 68 

 (b) If the Parent Guarantor and the Borrower have provided title information for additional
Properties under Section 8.13(a), the Parent Guarantor and the Borrower shall, within 60 days of notice from the Administrative Agent that title defects or exceptions exist with respect to such additional Properties, either (i) cure any
such title defects or exceptions (including defects or exceptions as to priority) which are not permitted by Section 9.03 raised by such information, (ii) substitute acceptable Mortgaged Properties with no title defects or exceptions
except for Excepted Liens (other than Excepted Liens described in clauses (e), (g) and (h) of such definition) having an equivalent value or (iii) deliver title information in form and substance acceptable to the Administrative Agent

Reserve Report. 
 (c) If the Parent Guarantor and the Borrower are unable to cure any title defect requested by the
Administrative Agent or the Lenders to be cured within the 60-day period or the Parent Guarantor and the Borrower do not comply with the requirements to provide acceptable title information covering 80% of the value of the Oil and Gas Properties
evaluated in the most recent Reserve Report, such default shall not be a Default, but instead the Administrative Agent and/or the Majority Lenders shall have the right to exercise the following remedy in their sole discretion from time to time, and
any failure to so exercise this remedy at any time shall not be a waiver as to future exercise of the remedy by the Administrative Agent or the Lenders. To the extent that the Administrative Agent or the Majority Lenders are not satisfied with title
to any Mortgaged Property after the 60-day period has elapsed, such unacceptable Mortgaged Property shall not count towards the 80% requirement, and the Administrative Agent may send a notice to the Parent Guarantor, the Borrower and the Lenders
that the then outstanding Borrowing Base shall be reduced by an amount as determined by the Majority Lenders to cause the Parent Guarantor and the Borrower to be in compliance with the requirement to provide acceptable title information on 80% of
the value of the Oil and Gas Properties. This new Borrowing Base shall become effective immediately after receipt of such notice. 
 Section 8.14 Additional Collateral; Additional Guarantors. 
 (a) In
connection with each redetermination of the Borrowing Base, the Borrower shall review the Reserve Report and the list of current Mortgaged Properties (as described in Section 8.12(c)(vi)) to ascertain whether the Mortgaged Properties represent
at least 80% of the total value of the Oil and Gas Properties evaluated in the most recently completed Reserve Report after giving effect to exploration and production activities, acquisitions, dispositions and production. In the event that the
Mortgaged Properties do not represent at least 80% of such total value, then the Parent Guarantor and the Borrower shall, and shall cause their Subsidiaries to, grant, within thirty (30) days of delivery of the certificate required under
Section 8.12(c), to the Administrative Agent as security for the Indebtedness a first-priority Lien interest (provided that Excepted Liens of the type described in clauses (a) to (d) and (f) of the definition thereof may exist,
but subject to the provisos at the end of such definition) on additional Oil and Gas Properties not already subject to a Lien of the Security Instruments such that after giving effect thereto, the Mortgaged Properties will represent at least 80% of
such total value. All such Liens will be created and perfected by and in accordance with the provisions of deeds of trust, 

  
 69 

 
security agreements and financing statements or other Security Instruments, all in form and substance reasonably satisfactory to the Administrative Agent and in sufficient executed (and
acknowledged where necessary or appropriate) counterparts for recording purposes. In order to comply with the foregoing, if any Subsidiary places a Lien on its Oil and Gas Properties and such Subsidiary is not a Guarantor, then it shall become a
Guarantor and comply with Section 8.14(b). 
 (b) The Parent Guarantor and the Borrower shall promptly cause each of their
Subsidiaries to guarantee the Indebtedness pursuant to the Guaranty Agreement. In connection with any such guaranty, the Parent Guarantor and the Borrower shall, or shall cause such Subsidiary to, promptly, but in any event no later than 15 days
after the formation or acquisition (or other similar event) of such Subsidiary to, (i) execute and deliver a supplement to the Guaranty Agreement executed by such Subsidiary, (ii) pledge all of the Equity Interests of such new Subsidiary

Plan or any trust created thereunder, (ii) immediately upon becoming aware of the occurrence of any “prohibited transaction,” as described in section 406 of ERISA or in section 4975 of the Code, in connection with any Plan or
any trust created thereunder, a written notice signed by the President or the principal Financial Officer, the Subsidiary or the ERISA Affiliate, as the case may be, specifying the nature thereof, what action the Parent Guarantor, the Borrower, the
Subsidiary 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 or the Department of Labor with respect thereto.

other similar contracts that are usual and customary in the oil and gas business and (iii) other contracts for the purchase and/or sale of Hydrocarbons of third parties (A) which have generally offsetting provisions (i.e. corresponding
pricing mechanics, delivery dates and points and volumes) such that no “position” is taken and (B) for which appropriate credit support has been taken to alleviate the material credit risks of the counterparty thereto.

  
 70 

 Section 8.17 Swap Agreements. To the extent the Borrower or a Subsidiary changes
the material terms of any Swap Agreement, terminates any such Swap Agreement or enters into a new Swap Agreement which has the effect of creating an off-setting position, the Borrower will give the Lenders prompt written notice of such event and
concurrently with such notice the Majority Lenders shall have the right to adjust the Borrowing Base in accordance with Section 2.07(e).

Agent as its agent and authorizes the Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent by the terms hereof and the other Loan Documents, together with such actions and
powers as are reasonably incidental thereto. 

  
 82 

 Section 11.02 Duties and Obligations of Administrative Agent. The Administrative
Agent shall not have any duties or obligations except those expressly set forth in the Loan Documents. Without limiting the generality of the foregoing, (a) the Administrative Agent shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing (the use of the term “agent” herein and in the other Loan Documents with reference to the Administrative Agent is not intended to connote any fiduciary or other implied
(or express) obligations arising under agency doctrine of any applicable law; rather, such term is used merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting
parties), (b) the Administrative Agent shall have no duty to take any discretionary action or exercise any discretionary powers, except as provided in Section 11.03, and (c) except as expressly set forth herein, the Administrative
Agent shall not have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to the Parent Guarantor, the Borrower or any of their Subsidiaries that is communicated to or obtained by the bank serving as
Administrative Agent or any of its Affiliates in any capacity. The Administrative Agent shall be deemed not to have knowledge of any Default unless and until written notice thereof is given to the Administrative Agent by the Parent Guarantor, the
Borrower or a Lender, and shall not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Agreement or any other Loan Document, (ii) the contents
of any certificate, report or other document delivered hereunder or under any other Loan Document or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set
forth herein or in any other Loan Document, (iv) the validity, enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document, (v) the satisfaction of any condition
set forth in ARTICLE VI or elsewhere herein, other than to confirm receipt of items expressly required to be delivered to the Administrative Agent or as to those conditions precedent expressly required to be to the Administrative Agent’s
satisfaction, (vi) the existence, value, perfection or priority of any collateral security or the financial or other condition of the Parent Guarantor, the Borrower and their Subsidiaries or any other obligor or guarantor, or (vii) any
failure by the Borrower or any other Person (other than itself) to perform any of its obligations hereunder or under any other Loan Document or the performance or observance of any covenants, agreements or other terms or conditions set forth herein
or therein. For purposes of determining compliance with the conditions specified in ARTICLE VI, each Lender shall be deemed to have consented to, approved or accepted or to be satisfied with, each document or other matter required thereunder to be
consented to or approved by or acceptable or satisfactory to a Lender unless the Administrative Agent shall have received written notice from such Lender prior to the proposed closing date specifying its objection thereto. 

Section 11.03 Action by Administrative Agent. The Administrative Agent shall have no duty to take any discretionary action or
exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise in writing as directed by the Majority Lenders (or such
other number or percentage of the Lenders as shall be necessary under the circumstances as provided in Section 12.02) and in all cases the Administrative Agent shall be fully justified in failing or refusing to act hereunder or under any other
Loan Documents unless it shall (a) receive written instructions from the Majority Lenders or the Lenders, as applicable, (or such other number or percentage of the Lenders as shall be necessary under the circumstances as provided in
Section 12.02) specifying the action to be taken and (b) be indemnified to its satisfaction by the Lenders against any and all liability and expenses which may be incurred by it by reason of 

  
 83 

 
taking or continuing to take any such action. The instructions as aforesaid and any action taken or failure to act pursuant thereto by the Administrative Agent shall be binding on all of the
Lenders. If a Default has occurred and is continuing, then the Administrative Agent shall take such action with respect to such Default as shall be directed by the requisite Lenders in the written instructions (with indemnities) described in this
Section 11.03, provided that, unless and until the Administrative Agent shall have received such directions, the Administrative Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such
Default as it shall deem advisable in the best interests of the Lenders. In no event, however, shall the Administrative Agent be required to take any action which exposes the Administrative Agent to personal liability or which is contrary to this
Agreement, the Loan Documents or applicable law. The Administrative Agent shall not be liable for any action taken or not taken by it with the consent or at the request of the Majority Lenders or the Lenders (or such other number or percentage of
the Lenders as shall be necessary under the circumstances as provided in Section 12.02), and otherwise the Administrative Agent shall not be liable for any action taken or not taken by it hereunder or under any other Loan Document or under any
other document or instrument referred to or provided for herein or therein or in connection herewith or therewith INCLUDING ITS OWN ORDINARY NEGLIGENCE, except for its own gross negligence or willful misconduct. 

Section 11.04 Reliance by Administrative Agent. The Administrative Agent shall be entitled to rely upon, and shall not incur
any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it to be genuine and to have been signed or sent by the proper Person. The Administrative Agent also may rely
upon any statement made to it orally or by telephone and believed by it to be made by the proper Person, and shall not incur any liability for relying thereon and each of the Parent Guarantor, the Borrower, the Lenders and the Issuing Bank hereby
waives the right to dispute the Administrative Agent’s record of such statement, except in the case of gross negligence or willful misconduct by the Administrative Agent. The Administrative Agent may consult with legal counsel (who may be
counsel for the Parent Guarantor and the Borrower), independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.
The Administrative Agent may deem and treat the payee of any Note as the holder thereof for all purposes hereof unless and until a written notice of the assignment or transfer thereof permitted hereunder shall have been filed with the Administrative
Agent. 
 Section 11.05 Subagents. The Administrative Agent may perform any and all its duties and exercise its
rights and powers by or through any one or more sub-agents appointed by the Administrative Agent. The Administrative Agent and any such sub-agent may perform any and all its duties and exercise its rights and powers through their respective Related
Parties. The exculpatory provisions of the preceding Sections of this ARTICLE XI shall apply to any such sub-agent and to the Related Parties of the Administrative Agent and any such sub-agent, and shall apply to their respective activities in
connection with the syndication of the credit facilities provided for herein as well as activities as Administrative Agent. 

Section 11.06 Resignation of the Administrative Agent. Subject to the appointment and acceptance of a successor
Administrative Agent as provided in this Section 11.06, the Administrative Agent may resign at any time by notifying the Lenders, the Issuing Bank and the 

  
 84 

 
Borrower. Upon any such resignation, the Majority Lenders shall have the right, in consultation with the Borrower, to appoint a successor. If no successor shall have been so appointed by the
Majority Lenders and shall have accepted such appointment within 30 days after the retiring Administrative Agent gives notice of its resignation, then the retiring Administrative Agent may, on behalf of the Lenders and the Issuing Bank, appoint a
successor Administrative Agent. Upon the acceptance of its appointment as Administrative Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged from its duties and obligations hereunder. The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor
unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this ARTICLE XI and Section 12.03 shall continue in effect for the benefit of such retiring
Administrative Agent, its sub-agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent. 

Section 11.07 Administrative Agent as Lender. The bank serving as the Administrative Agent hereunder shall have the same
rights and powers in its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and such bank and its Affiliates may accept deposits from, lend money to and generally engage in any kind of
business with the Parent Guarantor, the Borrower or any of their Subsidiaries or other Affiliate thereof as if it were not the Administrative Agent hereunder. 
 Section 11.08 No Reliance. Each Lender acknowledges that it has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and
information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and each other Loan Document to which it is a party. Each Lender also acknowledges that it will, independently and without reliance upon
the Administrative Agent or any other Lender and based on such documents and information as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any other
Loan Document, any related agreement or any document furnished hereunder or thereunder. The Administrative Agent shall not be required to keep itself informed as to the performance or observance by the Parent Guarantor, the Borrower or any of their
Subsidiaries of this Agreement, the Loan Documents or any other document referred to or provided for herein or to inspect the Properties or books of the Parent Guarantor, the Borrower or any of their Subsidiaries. Except for notices, reports and
other documents and information expressly required to be furnished to the Lenders by the Administrative Agent hereunder, neither the Administrative Agent nor the Arranger shall have any duty or responsibility to provide any Lender with any credit or
other information concerning the affairs, financial condition or business of the Parent Guarantor or the Borrower (or any of their Affiliates) which may come into the possession of the Administrative Agent or any of its Affiliates. In this regard,
each Lender acknowledges that Simpson Thacher & Bartlett LLP is acting in this transaction as special counsel to the Administrative Agent only, except to the extent otherwise expressly stated in any legal opinion or any Loan Document. Each
other party hereto will consult with its own legal counsel to the extent that it deems necessary in connection with the Loan Documents and the matters contemplated therein.

 Section 11.09 Administrative Agent May File Proofs of Claim. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Parent Guarantor, the Borrower or any of their Subsidiaries, the Administrative
Agent (irrespective of whether the principal of any Loan shall then be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent shall have made any demand on the Borrower) shall be
entitled and empowered, by intervention in such proceeding or otherwise: 
 (a) to file and prove a claim for the whole amount
of the principal and interest owing and unpaid in respect of the Loans and all other Indebtedness that are owing and unpaid and to file such other documents as may be necessary or advisable in order to have the claims of the Lenders and the
Administrative Agent (including any claim for the reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective agents and counsel and all other amounts due the Lenders and the
Administrative Agent under Section 12.03) allowed in such judicial proceeding; and 
 (b) to collect and receive any monies
or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Lender to make such payments to the Administrative Agent and, in the event that the Administrative Agent shall consent to the making of
such payments directly to the Lenders, to pay to the Administrative Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its agents and counsel, and any other amounts due the
Administrative Agent under Section 12.03. 
 Nothing contained herein shall be deemed to authorize the Administrative Agent
to authorize or consent to or accept or adopt on behalf of any Lender any plan of reorganization, arrangement, adjustment or composition affecting the Indebtedness or the rights of any Lender or to authorize the Administrative Agent to vote in
respect of the claim of any Lender in any such proceeding. 
 Section 11.10 Authority of Administrative Agent to Release
Collateral and Liens. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to (i) release any collateral that is permitted to be sold or released pursuant to the terms of the Loan Documents, (ii) release any
Guarantor from the Guaranty Agreement pursuant to the terms thereof and (iii) subordinate any Lien on any collateral granted to or held by the Administrative Agent under any Loan Document to the holder of any Lien permitted pursuant to
Section 9.03. Each Lender and the Issuing Bank hereby authorizes the Administrative Agent to execute and deliver to the Borrower, at the Borrower’s sole cost and expense, any and all releases of Liens, termination statements, assignments
or other documents reasonably requested by the Borrower in connection with any sale or other disposition of Property to the extent such sale or other disposition is permitted by the terms of Section 9.12 or is otherwise authorized by the terms
of the Loan Documents.

 Section 12.02 Waivers; Amendments. 

(a) No failure on the part of the Administrative Agent, the Issuing Bank or any Lender to exercise and no delay in exercising, and no
course of dealing with respect to, any right, power or privilege, or any abandonment or discontinuance of steps to enforce such right, power or privilege, under any of the Loan Documents shall operate as a waiver thereof, nor shall any single or
partial exercise of any right, power or privilege under any of the Loan Documents preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies of the Administrative Agent, the Issuing
Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of this Agreement or any other Loan Document or consent to
any departure by the Parent Guarantor, the Borrower or any of their Subsidiaries therefrom shall in any event be effective unless the same shall be permitted by Section 12.02(b), and then such waiver or consent shall be effective only in the
specific instance and for the purpose for which given. Without limiting the generality of the foregoing, the making of a Loan or issuance of a Letter of Credit shall not be construed as a waiver of any Default, regardless of whether the
Administrative Agent, any Lender or the Issuing Bank may have had notice or knowledge of such Default at the time. 
 (b)
Neither this Agreement nor any provision hereof nor any Security Instrument nor any provision thereof may be waived, amended or modified except pursuant to an agreement or agreements in writing entered into by the Parent Guarantor, the Borrower and
the Majority Lenders or by the Parent Guarantor, the Borrower and the Administrative Agent with the consent of the Majority Lenders; provided that no such agreement shall (i) increase the Commitment or the Maximum Credit Amount of any Lender
without the written consent of such Lender, (ii) increase the Borrowing Base, the Conforming Borrowing Base or the Non-Conforming Borrowing Base without the written consent of each Lender, decrease or maintain the Borrowing Base, the Conforming
Borrowing Base or the Non-Conforming Borrowing Base without the consent of the Majority Lenders, extend the Non-Conforming Period, or modify Section 2.07 in any manner without the consent of each Lender; provided that a Scheduled
Redetermination may be postponed by the Majority Lenders, (iii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, or reduce any other Indebtedness hereunder
or under any other Loan Document, without the written consent of each Lender affected thereby, (iv) postpone the scheduled date of payment or prepayment of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any
fees payable hereunder, or any other Indebtedness hereunder or under any other Loan Document, or reduce the amount of, waive or excuse any such payment, or postpone or extend the Termination Date without the written consent of each Lender affected
thereby, (v) change Section 4.01(b) or Section 4.01(c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (vi) waive or amend Section 3.04(c),
Section 6.01, Section 8.14 or Section 12.14 or change the definition of the terms “Domestic Subsidiary”, “Foreign Subsidiary” or “Subsidiary”, without the written consent of each Lender; provided that any
waiver or amendment to Section 12.14, this proviso in this Section 12.02(b)(vi), or Section 12.02(b)(vii), shall also require the written consent of each adversely affected Secured Swap Party, (vii) modify the terms of
Section 10.02(c) without the written consent of each Lender and Secured Swap Party adversely affected thereby or amend or otherwise modify any Security Instrument in a manner that results in the Secured Swap

  
 88 

 
Obligations secured by such Security Instrument no longer being secured thereby, or amend or otherwise change the definition of “Secured Swap Agreement”, “Secured Swap
Obligations” or “Secured Swap Party”, without the written consent of each Secured Swap Party adversely affected thereby, (viii) release any Guarantor (except as set forth in the Guaranty Agreement), release all or substantially
all of the collateral (other than as provided in Section 11.10), or reduce the percentage set forth in Section 8.14(a), without the written consent of each Lender, or (ix) change any of the provisions of this Section 12.02(b) or
the definition of “Majority Lenders” or any other provision hereof specifying the number or percentage of Lenders required to waive, amend or modify any rights hereunder or under any other Loan Documents or make any determination or grant
any consent hereunder or any other Loan Documents, without the written consent of each Lender; provided further that no such agreement shall amend, modify or otherwise affect the rights or duties of the Administrative Agent, or the Issuing Bank
hereunder or under any other Loan Document without the prior written consent of the Administrative Agent, or the Issuing Bank, as the case may be. Notwithstanding the foregoing, any supplement to Schedule 7.14 (Subsidiaries) shall be effective
simply by delivering to the Administrative Agent a supplemental schedule clearly marked as such and, upon receipt, the Administrative Agent will promptly deliver a copy thereof to the Lenders. 

Section 12.03 Expenses, Indemnity; Damage Waiver. 
 (a) The Borrower shall pay (i) all reasonable out-of-pocket expenses incurred by the Administrative Agent and its Affiliates, including, without limitation, the reasonable fees, charges and
disbursements of counsel and other outside consultants for the Administrative Agent, the reasonable travel, photocopy, mailing, courier, telephone and other similar expenses, and the cost of environmental invasive and non-invasive assessments and
audits and surveys and appraisals, in connection with the syndication of the credit facilities provided for herein, the preparation, negotiation, execution, delivery and administration (both before and after the execution hereof and including advice
of counsel to the Administrative Agent as to the rights and duties of the Administrative Agent and the Lenders with respect thereto) of this Agreement and the other Loan Documents and any amendments, modifications or waivers of or consents related
to the provisions hereof or thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all costs, expenses, Taxes, assessments and other charges incurred by the Administrative Agent or any Lender in
connection with any filing, registration, recording or perfection of any security interest contemplated by this Agreement or any Security Instrument or any other document referred to therein, (iii) all reasonable out-of-pocket expenses incurred
by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder, and (iv) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any
Lender, including the fees, charges and disbursements of any counsel for the Administrative Agent, the Issuing Bank or any Lender, in connection with the enforcement or protection of its rights in connection with this Agreement or any other Loan
Document, including its rights under this Section 12.03, or in connection with the Loans made or Letters of Credit issued hereunder, including, without limitation, all such out-of-pocket expenses incurred during any workout, restructuring or
negotiations in respect of such Loans or Letters of Credit. 

  
 89

AND EACH LENDER, AND EACH RELATED PARTY OF ANY OF THE FOREGOING PERSONS (EACH SUCH PERSON BEING CALLED AN “INDEMNITEE”) AGAINST, AND DEFEND AND HOLD EACH INDEMNITEE HARMLESS FROM, ANY AND ALL LOSSES, CLAIMS, DAMAGES, LIABILITIES AND
RELATED EXPENSES, INCLUDING THE REASONABLE FEES, CHARGES AND DISBURSEMENTS OF ANY COUNSEL FOR ANY INDEMNITEE, INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE ARISING OUT OF, IN CONNECTION WITH, OR AS A RESULT OF (i) THE EXECUTION OR DELIVERY OF

CONSUMMATION OF THE TRANSACTIONS CONTEMPLATED HEREBY OR BY ANY OTHER LOAN DOCUMENT, (ii) THE FAILURE OF THE PARENT GUARANTOR, THE BORROWER OR ANY OF THEIR SUBSIDIARIES TO COMPLY WITH THE TERMS OF ANY LOAN DOCUMENT, INCLUDING THIS AGREEMENT, OR
WITH ANY GOVERNMENTAL REQUIREMENT, (iii) ANY INACCURACY OF ANY REPRESENTATION OR ANY BREACH OF ANY WARRANTY OR COVENANT OF THE PARENT GUARANTOR, THE BORROWER OR ANY OTHER GUARANTOR SET FORTH IN ANY OF THE LOAN DOCUMENTS OR ANY INSTRUMENTS,
DOCUMENTS OR CERTIFICATIONS DELIVERED IN CONNECTION THEREWITH, (iv) ANY LOAN OR LETTER OF CREDIT OR THE USE OF THE PROCEEDS THEREFROM, INCLUDING, WITHOUT LIMITATION, (A) ANY REFUSAL BY THE ISSUING BANK TO HONOR A DEMAND FOR PAYMENT UNDER A
LETTER OF CREDIT IF THE DOCUMENTS PRESENTED IN CONNECTION WITH SUCH DEMAND DO NOT STRICTLY COMPLY WITH THE TERMS OF SUCH LETTER OF CREDIT, OR (B) THE PAYMENT OF A DRAWING UNDER ANY LETTER OF CREDIT NOTWITHSTANDING THE NON-COMPLIANCE,
NON-DELIVERY OR OTHER IMPROPER PRESENTATION OF THE DOCUMENTS PRESENTED IN CONNECTION THEREWITH, (v) ANY OTHER ASPECT OF THE LOAN DOCUMENTS, (vi) THE OPERATIONS OF THE BUSINESS OF THE PARENT GUARANTOR, THE BORROWER AND THEIR SUBSIDIARIES BY
THE PARENT GUARANTOR, THE BORROWER AND THEIR SUBSIDIARIES, (vii) ANY ASSERTION THAT THE LENDERS WERE NOT ENTITLED TO RECEIVE THE PROCEEDS RECEIVED PURSUANT TO THE SECURITY INSTRUMENTS, (viii) ANY ENVIRONMENTAL LAW APPLICABLE TO THE PARENT
GUARANTOR, THE BORROWER OR ANY OF THEIR SUBSIDIARIES OR ANY OF THEIR PROPERTIES OR OPERATIONS, INCLUDING THE PRESENCE, GENERATION, STORAGE, RELEASE, THREATENED RELEASE, USE, TRANSPORT, DISPOSAL, ARRANGEMENT OF DISPOSAL OR TREATMENT OF HAZARDOUS
MATERIALS ON OR AT ANY OF THEIR PROPERTIES, (ix) THE BREACH OR NON-COMPLIANCE BY THE PARENT GUARANTOR, THE BORROWER OR ANY OF THEIR SUBSIDIARIES WITH ANY ENVIRONMENTAL LAW APPLICABLE TO THE PARENT GUARANTOR, THE BORROWER OR ANY OF THEIR

PROSPECTIVE CLAIM, LITIGATION, INVESTIGATION OR PROCEEDING RELATING TO ANY OF THE FOREGOING, WHETHER BASED ON CONTRACT, TORT OR ANY OTHER THEORY AND REGARDLESS OF WHETHER ANY INDEMNITEE IS A PARTY THERETO, AND SUCH INDEMNITY SHALL EXTEND TO EACH
INDEMNITEE NOTWITHSTANDING THE SOLE OR CONCURRENT NEGLIGENCE OF EVERY KIND OR CHARACTER WHATSOEVER, WHETHER ACTIVE OR PASSIVE, WHETHER AN AFFIRMATIVE ACT OR AN OMISSION, INCLUDING WITHOUT LIMITATION, ALL TYPES OF NEGLIGENT CONDUCT IDENTIFIED IN THE
RESTATEMENT (SECOND) OF TORTS OF ONE OR MORE OF THE INDEMNITEES OR BY REASON OF STRICT LIABILITY IMPOSED WITHOUT FAULT ON ANY ONE OR MORE OF THE INDEMNITEES; PROVIDED THAT SUCH INDEMNITY SHALL NOT, AS TO ANY INDEMNITEE, BE AVAILABLE TO THE EXTENT
THAT SUCH LOSSES, CLAIMS, DAMAGES, LIABILITIES OR RELATED EXPENSES ARE DETERMINED BY A COURT OF COMPETENT JURISDICTION BY FINAL AND NONAPPEALABLE JUDGMENT TO HAVE RESULTED FROM THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF SUCH INDEMNITEE.

 (c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent, the
Arranger or the Issuing Bank under Section 12.03(a) or (b), each Lender severally agrees to pay to the Administrative Agent, the Arranger or the Issuing Bank, as the case may be, such Lender’s Applicable Percentage (determined as of the
time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or
asserted against the Administrative Agent, the Arranger or the Issuing Bank in its capacity as such. 
 (d) To the extent
permitted by applicable law, the Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising
out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof. 

(e) All amounts due under this Section 12.03 shall be payable not later than three days after written demand therefor.

 Section 12.04 Successors and Assigns. 

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors
and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) other than in connection with a transaction permitted under Section 9.12(e), the Parent Guarantor and the Borrower
may not assign or otherwise transfer any of their rights or obligations hereunder without the prior written consent of each Lender, such consent not to be unreasonably withheld (and any attempted assignment or transfer by the Parent Guarantor or the
Borrower in violation of this Section 12.04(a)(i) shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section 12.04. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants
(to the extent provided in Section 12.04(c)) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by
reason of this Agreement. 
 (b) (i) Subject to the conditions set forth in Section 12.04(b)(ii), any Lender may assign to
one or more assignees all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably
withheld) of: 
 (A) the Borrower, provided that no consent of the Borrower shall be required if such assignment is to a
Lender, an Affiliate of a Lender, or, if an Event of Default has occurred and is continuing, is to any other assignee; and 

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment to an assignee
that is a Lender immediately prior to giving effect to such assignment. 
 (ii) Assignments shall be subject to the following
additional conditions: 
 (A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of
the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to
such assignment is delivered to the Administrative Agent) shall not be less than $5,000,000 unless the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default
has occurred and is continuing; 
 (B) each partial assignment shall be made as an assignment of a proportionate part of all
the assigning Lender’s rights and obligations under this Agreement; 
 (C) the parties to each assignment shall execute
and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; 

  
 92 

 (D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an
Administrative Questionnaire; and 
 (E) no assignment shall be made to (i) the Borrower or any of the Borrower’s
Subsidiaries or Affiliates, (ii) any Defaulting Lender or any of its Subsidiaries, or any Person who, upon becoming a Lender hereunder, would constitute any of the foregoing Persons described in this clause (ii) or (iii) any natural
Person. 
 (iii) Subject to Section 12.04(b)(iv) and the acceptance and recording thereof, from and after the effective
date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the
assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning
Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Section 5.01, Section 5.02, Section 5.03 and Section 12.03). Any
assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.04 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and
obligations in accordance with Section 12.04(c). 
 (iv) The Administrative Agent, acting for this purpose as an agent of
the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Maximum Credit Amount of, and principal amount of the
Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Parent Guarantor, the Borrower, the Administrative Agent, the
Issuing Bank and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available
for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice. In connection with any changes to the Register, if necessary, the Administrative Agent will reflect the
revisions on Annex I and forward a copy of such revised Annex I to the Borrower, the Issuing Bank and each Lender. 
 (v) Upon
its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and
recordation fee referred to in Section 12.04(b) and any written consent to such assignment required by Section 12.04(b), the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in
the Register. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 12.04(b). 
 (c) (i) Any Lender may, without the consent of the Parent Guarantor, the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a
“Participant”) in all or a portion of such Lender’s rights and obligations under 

  
 93 

 
this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged,
(B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations and (C) the Parent Guarantor, the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue
to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall
retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the
Participant, agree to any amendment, modification or waiver described in the proviso to Section 12.02 that affects such Participant. In addition such agreement must provide that the Participant be bound by the provisions of Section 12.03.
Subject to Section 12.04(c)(ii), the Parent Guarantor and the Borrower agree that each Participant shall be entitled to the benefits of Section 5.01, Section 5.02 and Section 5.03 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to Section 12.04(b). To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 12.08 as though it were a Lender, provided such Participant agrees to be
subject to Section 4.01(c) as though it were a Lender. 
 (ii) A Participant shall not be entitled to receive any greater
payment under Section 5.01 or Section 5.03 than the applicable Lender would have been entitled to receive with respect to the participation sold to such Participant, unless the sale of the participation to such Participant is made with the
Borrower’s prior written consent. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.03 unless the Borrower is notified of the participation sold to such Participant and such
Participant agrees, for the benefit of the Borrower, to comply with Section 5.03(e) as though it were a Lender. 
 (d) Any
Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank, and
Section 12.04(b) shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such
pledgee or assignee for such Lender as a party hereto. 
 (e) Notwithstanding any other provisions of this Section 12.04,
no transfer or assignment of the interests or obligations of any Lender or any grant of participations therein shall be permitted if such transfer, assignment or grant would require the Parent Guarantor, the Borrower or any of their Subsidiaries to
file a registration statement with the SEC or to qualify the Loans under the “Blue Sky” laws of any state. 

Section 12.05 Survival; Revival; Reinstatement. 
 (a) All covenants, agreements, representations and warranties made by the Parent Guarantor, the Borrower and the other Guarantors herein and in the certificates or other instruments delivered in
connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall 

  
 94 

 
survive the execution and delivery of this Agreement and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its
behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full
force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments have not
expired or terminated. The provisions of Section 5.01, Section 5.02, Section 5.03 and Section 12.03 and ARTICLE XI shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated
hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement, any other Loan Document or any provision hereof or thereof. 

(b) To the extent that any payments on the Indebtedness or proceeds of any collateral are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee, debtor in possession, receiver or other Person under any bankruptcy law, common law or equitable cause, then to such extent, the Indebtedness so satisfied shall be revived
and continue as if such payment or proceeds had not been received and the Administrative Agent’s and the Lenders’ Liens, security interests, rights, powers and remedies under this Agreement and each Loan Document shall continue in full
force and effect. In such event, each Loan Document shall be automatically reinstated and the Parent Guarantor and the Borrower shall take such action as may be reasonably requested by the Administrative Agent and the Lenders to effect such
reinstatement. 
 Section 12.06 Counterparts; Integration; Effectiveness. 

(a) This Agreement may be executed in counterparts (and by different parties hereto on different counterparts), each of which shall
constitute an original, but all of which when taken together shall constitute a single contract. 
 (b) This Agreement, the

(of whatsoever kind, including, without limitations obligations under Swap Agreements) at any time owing by such Lender or Affiliate to or for the credit or the account of the Parent Guarantor, the Borrower or any of their Subsidiaries against any
of and all the obligations of the Parent Guarantor, the Borrower or any of their Subsidiaries owed to such Lender now or hereafter existing under this Agreement or any other Loan Document, irrespective of whether or not such Lender shall have made

and the Issuing Bank agrees to notify the Parent Guarantor, the Borrower and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and
application.

 Section 12.11 Confidentiality. Each of the Administrative Agent, the Issuing
Bank and the Lenders agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants,
legal counsel and other advisors (it being understood that the Persons to whom such disclosure is made will be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent
requested by any regulatory authority, (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party to this Agreement or any other Loan Document, (e) in connection
with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions substantially the same as those of this Section 12.11, to (i) any assignee of or Participant in, or any prospective assignee of or Participant in, any of its rights or obligations under this Agreement or
(ii) any actual or prospective counterparty (or its advisors) to any Swap Agreement relating to the Borrower and its obligations, (g) with the consent of the Borrower or (h) to the extent such Information (i) becomes publicly
available other than as a result of a breach of this Section 12.11 or (ii) becomes available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis from a source other than the Parent Guarantor, the Borrower
or any of their Subsidiaries. For the purposes of this Section 12.11, “Information” means all information received from the Parent Guarantor, the Borrower or any of their Subsidiaries relating to the Parent Guarantor’s,
the Borrower’s or any of their Subsidiaries’ businesses, other than any such information that is available to the Administrative Agent, the Issuing Bank or any Lender on a nonconfidential basis prior to disclosure by the Parent Guarantor,
the Borrower or any of their Subsidiaries; provided that, in the case of information received from the Parent Guarantor, the Borrower or any of their Subsidiaries after the date hereof, such information is hereby deemed at the time of delivery as
confidential. Any Person required to maintain the confidentiality of Information as provided in this Section 12.11 shall be considered to have complied with its obligation to do so if such Person has exercised the same degree of care to
maintain the confidentiality of such Information as such Person would accord to its own confidential information. 

Section 12.12 Interest Rate Limitation. It is the intention of the parties hereto that each Lender shall conform strictly to
usury laws applicable to it. Accordingly, if the transactions contemplated hereby would be usurious as to any Lender under laws applicable to it (including the laws of the United States of America and the State of Texas or any other jurisdiction
whose laws may be mandatorily applicable to such Lender notwithstanding the other provisions of this Agreement), then, in that event, notwithstanding anything to the contrary in any of the Loan Documents or any agreement entered into in connection
with or as security for the Notes, it is agreed as follows: (i) the aggregate of all consideration which constitutes interest under law applicable to any Lender that is contracted for, taken, reserved, charged or received by such Lender under
any of the Loan Documents or agreements or otherwise in connection with the Notes shall under no circumstances exceed the maximum amount allowed by such applicable law, and any excess shall be canceled automatically and if theretofore paid shall be
credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower); and (ii) in the
event that the maturity of the Notes is accelerated by reason of an election of the holder thereof resulting from any Event of Default under this 

  
 98 

 
Agreement or otherwise, or in the event of any required or permitted prepayment, then such consideration that constitutes interest under law applicable to any Lender may never include more than
the maximum amount allowed by such applicable law, and excess interest, if any, provided for in this Agreement or otherwise shall be canceled automatically by such Lender as of the date of such acceleration or prepayment and, if theretofore paid,
shall be credited by such Lender on the principal amount of the Indebtedness (or, to the extent that the principal amount of the Indebtedness shall have been or would thereby be paid in full, refunded by such Lender to the Borrower). All sums paid
or agreed to be paid to any Lender for the use, forbearance or detention of sums due hereunder shall, to the extent permitted by law applicable to such Lender, be amortized, prorated, allocated and spread throughout the stated term of the Loans
evidenced by the Notes until payment in full so that the rate or amount of interest on account of any Loans hereunder does not exceed the maximum amount allowed by such applicable law. If at any time and from time to time (i) the amount of
interest payable to any Lender on any date shall be computed at the Highest Lawful Rate applicable to such Lender pursuant to this Section 12.12 and (ii) in respect of any subsequent interest computation period the amount of interest
otherwise payable to such Lender would be less than the amount of interest payable to such Lender computed at the Highest Lawful Rate applicable to such Lender, then the amount of interest payable to such Lender in respect of such subsequent
interest computation period shall continue to be computed at the Highest Lawful Rate applicable to such Lender until the total amount of interest payable to such Lender shall equal the total amount of interest which would have been payable to such
Lender if the total amount of interest had been computed without giving effect to this Section 12.12. To the extent that Chapter 303 of the Texas Finance Code is relevant for the purpose of determining the Highest Lawful Rate applicable to a
Lender, such Lender elects to determine the applicable rate ceiling under such Chapter by the weekly ceiling from time to time in effect. Chapter 346 of the Texas Finance Code does not apply to the Borrower’s obligations hereunder. 

Section 12.13 EXCULPATION PROVISIONS. EACH OF THE PARTIES HERETO SPECIFICALLY AGREES THAT IT HAS A DUTY TO READ THIS
AGREEMENT AND THE OTHER LOAN DOCUMENTS AND AGREES THAT IT IS CHARGED WITH NOTICE AND KNOWLEDGE OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; THAT IT HAS IN FACT READ THIS AGREEMENT AND IS FULLY INFORMED AND HAS FULL NOTICE AND
KNOWLEDGE OF THE TERMS, CONDITIONS AND EFFECTS OF THIS AGREEMENT; THAT IT HAS BEEN REPRESENTED BY INDEPENDENT LEGAL COUNSEL OF ITS CHOICE THROUGHOUT THE NEGOTIATIONS PRECEDING ITS EXECUTION OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND HAS
RECEIVED THE ADVICE OF ITS ATTORNEY IN ENTERING INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS; AND THAT IT RECOGNIZES THAT CERTAIN OF THE TERMS OF THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS RESULT IN ONE PARTY ASSUMING THE LIABILITY INHERENT IN
SOME ASPECTS OF THE TRANSACTION AND RELIEVING THE OTHER PARTY OF ITS RESPONSIBILITY FOR SUCH LIABILITY. EACH PARTY HERETO AGREES AND COVENANTS THAT IT WILL NOT CONTEST THE VALIDITY OR ENFORCEABILITY OF ANY EXCULPATORY PROVISION OF THIS AGREEMENT AND
THE OTHER LOAN DOCUMENTS ON THE BASIS THAT THE PARTY HAD NO NOTICE OR KNOWLEDGE OF SUCH PROVISION OR THAT THE PROVISION IS NOT “CONSPICUOUS.” 

  
 99 

 Section 12.14 Collateral Matters; Swap Agreements. The benefit of the Security
Instruments and of the provisions of this Agreement relating to any collateral securing the Indebtedness shall also extend to and be available to Secured Swap Parties on a pro rata basis (but subject to the terms of the Loan Documents, including
provisions thereof relating to the application and priority of payments to the Persons entitled thereto) in respect of any Secured Swap Obligations. Except as expressly set forth in Section 12.02(b), no Secured Swap Party shall have any voting
rights under any Loan Document as a result of the existence of any Secured Swap Obligations owed to it. 
 Section 12.15
No Third Party Beneficiaries. This Agreement, the other Loan Documents, and the agreement of the Lenders to make Loans and the Issuing Bank to issue, amend, renew or extend Letters of Credit hereunder are solely for the benefit of the
Borrower, and no other Person (including, without limitation, the Parent Guarantor, any Subsidiary of the Borrower, any obligor, contractor, subcontractor, supplier or materialsman) shall have any rights, claims, remedies or privileges hereunder or
under any other Loan Document against the Administrative Agent, the Issuing Bank or any Lender for any reason whatsoever. There are no third party beneficiaries. 
 Section 12.16 USA Patriot Act Notice. Each Lender hereby notifies the Borrower that pursuant to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law
October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such
Lender to identify the Borrower in accordance with the Act. 
 Section 12.17 Flood Insurance Provisions.
Notwithstanding any provision in this Agreement or any other Loan Document to the contrary, in no event is any Building (as defined in the applicable Flood Insurance Regulation) or Manufactured (Mobile) Home (as defined in the applicable Flood
Insurance Regulation) included in the definition of “Mortgaged Property” and no Building or Manufactured (Mobile) Home is hereby encumbered by this Agreement or any other Loan Document. As used herein, “Flood Insurance
Regulations” means (a) the National Flood Insurance Act of 1968 as now or hereafter in effect or any successor statute thereto, (b) the Flood Disaster Protection Act of 1973 as now or hereafter in effect or any successor statue
thereto, (c) the National Flood Insurance Reform Act of 1994 (amending 42 USC 4001, et seq.), as the same may be amended or recodified from time to time and (d) the Flood Insurance Reform Act of 2004 and any regulations promulgated
thereunder.
