Change of Control Agreement

 Exhibit 10.30 
 CHANGE OF CONTROL AGREEMENT 
 THIS CHANGE
OF CONTROL AGREEMENT (the “Agreement”) is made effective as of June 1, 2010 (the “Effective Date”) between
ENTROPIC COMMUNICATIONS, INC. (“Entropic”), and Michael Farese (“Employee”), subject to the approval of the Entropic Board of Directors. 

RECITALS 

A. Employee is employed as the Senior Vice President, Engineering and Operations of Entropic. 

B. Employee and Entropic desire to memorialize in writing their understanding regarding severance payments and vesting acceleration of
stock options and/or other equity arrangements, including shares of restricted stock subject to repurchase options or other restrictions, in the event of a Change of Control. 
 C. Employee and Entropic acknowledge that this Agreement constitutes the entire agreement between the parties relating to severance benefits upon change of control and supersedes any and all other
agreements, either oral or in writing, between Employee and Entropic and all other subsidiaries or affiliates of Entropic with respect to the matters discussed herein. 
 AGREEMENT 
 In consideration of the promises and of the mutual covenants
contained herein, and for other good and valuable consideration, receipt of which is hereby acknowledged, the parties do hereby agree as follows: 
 1. EFFECT OF CERTAIN TERMINATIONS AFTER CHANGE OF CONTROL.

 1.1 Severance Package. If within one (1) year after a Change of Control (as that term is defined below)
Employee’s employment is terminated without “Cause,” or Employee resigns for “Good Reason,” then Entropic will provide Employee with the following “Severance Package,” provided Employee complies with the conditions
set forth in section 1.2 below: (i) Employee will receive a severance payment equal to twelve (12) months of Employee’s Base Salary (as defined below), payable in a single lump sum within ten (10) days following the effective
date of the release of claims required by Section 1.2 below, subject to applicable tax withholdings; (ii) Entropic will continue to provide Employee with health, dental and vision benefits by paying Employee’s Consolidated Omnibus
Budget Reconciliation Act of 1985 (“COBRA”) premiums directly to the COBRA administrator for six (6) months following the date of Employee’s termination, provided that Employee elects to continue and remain eligible
for these benefits under COBRA; (iii) expiration of the repayment obligation for any relocation assistance expenses paid to Employee; and (iv) immediate and accelerated vesting of all stock options and other equity arrangements subject to
vesting, and release of any repurchase options in favor of Entropic on shares of restricted stock that would otherwise be regularly scheduled to vest or be released, as applicable, within twenty-four (24) months following Employee’s
termination without Cause or voluntary resignation for Good Reason, to the extent permissible by law. For purposes of clarification, if a stock option or other equity arrangement is 

 
subject to performance- or milestone-based vesting or if the release of any repurchase option in favor of Entropic on shares of restricted stock is performance- or milestone-based, such
performance measure or milestone shall be deemed satisfied pursuant to clause (iii) above if absent such acceleration provision, in order for such vesting or release to occur such performance measure or milestone was required to be satisfied
within no later than twenty-four (24) months following Employee’s termination without Cause or voluntary resignation for Good Reason. Moreover, the acceleration of vesting provision set forth in this section 1.1 is notwithstanding and in
addition to any existing vesting provisions set forth in Entropic’s equity incentive plans or any agreements or grant notices thereunder. “Base Salary” shall mean Employee’s monthly base salary in effect immediately
prior to the Employee’s date of termination (including without limitation any compensation that is deferred by Employee into an Entropic-sponsored retirement or deferred compensation plan, exclusive of any employee matching contributions by
Entropic associated with any such retirement or deferred compensation plan and exclusive of any other Entropic contributions) and excludes all bonuses, commissions, expatriate premiums, fringe benefits (including without limitation car allowances),
option grants, equity awards, employee benefits and other similar items of compensation. For purposes of the Severance Package, Base Salary shall be computed without regard to any reduction in Base Salary that would provide Employee the right to
resign for Good Reason pursuant to Section 1.6(c). 
 1.2 Conditions to Receive Severance Package. The Severance
Package described above will be paid provided Employee meets the following conditions: (a) Employee complies with all surviving provisions of any confidentiality or proprietary rights agreement signed by Employee; and (b) promptly
following the Employee’s date of termination (but not more than forty-five (45) days after the Employee’s employment is terminated) Employee executes a full general release, in a form acceptable to Entropic, releasing all claims,
known or unknown, that Employee may have against Entropic, and any subsidiary or related entity, their officers, directors, employees and agents, arising out of or any way related to Employee’s employment or termination of employment with
Entropic, and permits such release to become effective in accordance with its terms. 
 1.3 280G. Notwithstanding
Section 1.1 above, if it is determined that the amounts payable to Employee under this Agreement, when considered together with any other amounts payable to Employee as a result of a Change of Control (collectively, the
“Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and (ii) but for this
sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then such Payment shall be equal to the Reduced Amount. The “Reduced Amount” shall be either
(x) the largest portion of the Payment that would result in no portion of the Payment being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount, after taking into account
all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Employee’s receipt, on an after-tax basis, of the greater amount of the Payment
notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in payments or benefits constituting “parachute payments” is necessary so that the Payment equals the Reduced Amount, reduction shall
occur in the following order: reduction of cash payments; reduction of accelerated vesting of stock options; reduction of employee benefits. In the event that 

 
acceleration of vesting of stock option compensation is to be reduced, such acceleration of vesting shall be cancelled in the reverse order of the date of grant of Employee’s stock options
(i.e., earliest granted stock option cancelled last). 
 The accounting firm engaged by Entropic for general audit
purposes as of the day prior to the effective date of the Change of Control shall perform the foregoing calculations. If the accounting firm so engaged by Entropic is serving as accountant or auditor for the individual, entity or group effecting the
Change of Control, Entropic shall appoint a nationally recognized accounting firm to make the determinations required hereunder. Entropic shall bear all expenses with respect to the determinations by such accounting firm required to be made
hereunder. 
 The accounting firm engaged to make the determinations hereunder shall provide its calculations, together with
detailed supporting documentation, to Employee and Entropic within fifteen (15) calendar days after the date on which Employee’s right to a Payment is triggered (if requested at that time by Employee or Entropic) or such other time as
requested by Employee or Entropic. If the accounting firm determines that no Excise Tax is payable with respect to a Payment, either before or after the application of the Reduced Amount, it shall furnish Employee and Entropic with an opinion
reasonably acceptable to Employee that no Excise Tax will be imposed with respect to such Payment. Any good faith determinations of the accounting firm made hereunder shall be final, binding and conclusive upon Employee and Entropic, except as set
forth below. 
 If, notwithstanding any reduction described in this Section 1.3, the IRS determines that Employee is liable
for the Excise Tax as a result of the receipt of the payment of benefits as described above, then Employee shall be obligated to pay back to Entropic, within thirty (30) days after a final IRS determination or in the event that Employee
challenges the final IRS determination, a final judicial determination, a portion of the payment equal to the “Repayment Amount.” The Repayment Amount with respect to the payment of benefits shall be the smallest such amount,
if any, as shall be required to be paid to Entropic so that Employee’s net after-tax proceeds with respect to any payment of benefits (after taking into account the payment of the Excise Tax and all other applicable taxes imposed on such
payment) shall be maximized. The Repayment Amount with respect to the payment of benefits shall be zero if a Repayment Amount of more than zero would not result in Employee’s net after-tax proceeds with respect to the payment of such benefits
being maximized. If the Excise Tax is not eliminated pursuant to this paragraph, Employee shall pay the Excise Tax. 

Notwithstanding any either provision of this Section 1.3, if (i) there is a reduction in the payment of benefits as described
in this section, (ii) the IRS later determines that Employee is liable for the Excise Tax, the payment of which would result in the maximization of Employee’s net after-tax proceeds (calculated as if Employee’s benefits had not
previously been reduced), and (iii) Employee pays the Excise Tax, then Entropic shall pay to Employee those benefits which were reduced pursuant to this section contemporaneously or as soon as administratively possible after Employee pays the
Excise Tax so that Employee’s net after-tax proceeds with respect to the payment of benefits is maximized. 
 1.4 Change
of Control. A “Change of Control” means: (i) the direct or indirect sale or exchange in a single or series of related transactions by the stockholders of 

 
Entropic of more than fifty percent (50%) of the voting stock of Entropic; (ii) a merger or consolidation in which Entropic is a party after which the stockholders of Entropic
immediately prior to such transaction hold less than fifty percent (50%) of the voting securities of the surviving entity; (iii) the sale, exchange, or transfer of all or substantially all of the assets of Entropic after which the
stockholders of Entropic immediately prior to such transaction hold less than fifty percent (50%) of the voting securities of the corporation or other business entity to which the assets of Entropic were transferred; or (iv) a liquidation
or dissolution of Entropic. 
 1.5 Termination for “Cause.” For purposes of this Agreement, a termination for
“Cause” occurs if Employee is terminated for any of the following reasons: (i) conviction of, or plea of nolo contendere to, a felony; (ii) theft or embezzlement, or attempted theft or embezzlement, of money or property or
assets of Entropic; (iii) termination consistent with the provisions and procedures of Entropic’s drug policy; (iv) continued neglect of Employee’s duties in connection with Employee’s employment by Entropic (not due to a
physical or mental illness), which continues for at least ten (10) days after written notice of demand for compliance is delivered to Employee by Entropic, which demand identifies the manner in which Entropic believes that Employee has not
performed such duties and the steps required to cure such failure to perform; or (v) intentional and willful engagement in misconduct which is materially injurious to Entropic. 

Notwithstanding the foregoing clause (iv), Employee may not be terminated for Cause as a result of his failure or inability to perform
assigned duties which are substantially inconsistent with his duties and responsibilities in effect during the year preceding the Change of Control (or such shorter period of time as Employee was employed by Entropic). 

Notwithstanding the foregoing clauses, Employee’s employment shall not be deemed to be terminated for Cause, and no other action
shall be taken by Entropic which is adverse to Employee hereunder unless and until there shall have been delivered to Employee a copy of a statement of the basis for Cause, signed and approved by an officer of Entropic. 

1.6 Voluntary Resignation for “Good Reason.” After a Change of Control, Employee may resign for “Good Reason”
upon the occurrence of any of the following conditions without the Employee’s consent; provided however, that any resignation by the Employee due to any of the following conditions shall only be deemed for Good Reason if: (i) the Employee
gives the Company written notice of the intent to resign for Good Reason within ninety (90) days following the first occurrence of the condition(s) that the Employee believes constitutes Good Reason, which notice shall describe such
condition(s); (ii) the Company fails to remedy, if remediable, such condition(s) within thirty (30) days following receipt of the written notice (the “Cure Period”) of such condition(s) from the Employee; and
(iii) Employee actually resigns employment within the first ninety (90) days after expiration of the Cure Period: 

(a) the assignment to Employee of any duties, or any limitation of Employee’s authority or responsibilities, substantially
inconsistent with Employee’s authority, duties, and responsibilities with Entropic immediately prior to the date of the Change of Control, in each case where such assignment or limitation constitutes a material reduction of Employee’s
authority, duties or responsibilities as in effect prior to the Change of Control, 

 (b) the relocation of the principal place of Employee’s service with Entropic
to a location that is more than fifty (50) miles from Employee’s principal place of service with Entropic immediately prior to the date of the Change of Control that requires a one-way increase in Employee’s driving distance of at
least thirty (30) miles, 
 (c) any material reduction by Entropic of Employee’s base salary in effect
immediately prior to the date of the Change of Control (unless reductions comparable in amount and duration are concurrently made for all other employees of Entropic with responsibilities, organizational level and title comparable to Employee), or

 (d) any failure by Entropic to continue to provide Employee with the opportunity to participate in any material
benefit or compensation plans and programs in which Employee was participating immediately prior to the date of the Change of Control, or their equivalent, which failure constitutes a material reduction in Employee’s base compensation.

 1.7 Payment Upon Death or Disability. Neither death nor disability shall affect Entropic’s obligations hereunder,
provided however that neither death nor disability shall be deemed to be Cause for termination. If within one (1) year following a Change of Control the Employee’s employment with Entropic terminates due to the Employee’s death or
“Complete Disability,” as defined below, Employee (or Employee’s beneficiaries or estate, as applicable) shall be eligible to receive the Severance Package in Section 1.1, subject to satisfaction of the conditions
in Section 1.2 by Employee or Employee’s beneficiaries or estate, as applicable. For purposes of eligibility to receive the Severance Package, “Complete Disability” means Employee is prevented from performing
Employee’s duties of employment with the Company by reason of any physical or mental incapacity that results in Employee’s satisfaction of all requirements necessary to receive benefits under the Company’s long-term disability plan
due to a total disability. 
 1.8 Application of Code Section 409A. Notwithstanding anything to the contrary herein,
the following provisions apply to the extent severance benefits provided herein are subject to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and other guidance thereunder
and any state law of similar effect (collectively “Section 409A”). Severance benefits shall not commence until Employee has a “separation from service” for purposes of Section 409A. The severance benefits are
intended to satisfy the exemptions from application of Section 409A provided under Treasury Regulations Sections 1.409A-1(b)(4) and 1.409A-1(b)(5). However, if such exemptions are not available and Employee is, upon separation from service, a
“specified employee” for purposes of Section 409A, then, solely to the extent necessary to avoid adverse personal tax consequences under Section 409A, the timing of the severance benefits payments shall be delayed until the
earlier of (i) six (6) months and one day after Employee’s separation from service, or (ii) Employee’s death. 
 2. AT-WILL EMPLOYMENT. Employee acknowledges that Employee continues as an at-will employee and agrees that nothing in this Agreement is intended to or
should be construed to contradict, modify or alter Employee’s at-will employment relationship with Entropic. 

 3. NO OTHER SEVERANCE
BENEFITS. Employee acknowledges and agrees that the Severance Package provided pursuant to this Agreement is in lieu of any other severance benefits to which Employee may be eligible under any other agreement and/or
Entropic severance plan or practice. Employee and Entropic further acknowledge that this Agreement constitutes the entire agreement between the parties relating to severance benefits upon change of control and supersedes any and all other
agreements, either oral or in writing, between Employee and Entropic and all other subsidiaries or affiliates of Entropic with respect to the matters discussed herein, including but not limited to the Prior Agreement. Notwithstanding the foregoing,
this Agreement shall not supersede the vesting acceleration provisions included in Entropic’s equity incentive plans or any other provisions of Employee’s equity award agreements or the Company’s equity incentive plans that are more
beneficial to Employee than this Agreement. 
 4. CERTAIN REDUCTIONS. To the
extent that any federal, state or local laws, including, without limitation the Worker Adjustment Retraining Notification Act, or any similar state statute, require Entropic to give advance notice or make a payment of any kind to Employee because of
Employee’s involuntary termination due to a layoff, reduction in force, plant or facility closing, sale of business, change of control, or any other similar event or reason, the benefits payable under this Agreement shall either be reduced or
eliminated by such required payments or notice. The benefits provided under this Agreement are intended to satisfy any and all statutory obligations that may arise out of Employee’s involuntary termination of employment for the foregoing
reasons. 
 5. GENERAL PROVISIONS. 

5.1 Severability. If any provision of this Agreement is held by a court of competent jurisdiction to be invalid, void or
unenforceable, the remaining provisions shall nevertheless continue in full force without being impaired or invalidated in any way. 
 5.2 Successors and Assigns. The rights and obligations of Entropic under this Agreement shall inure to the benefit of and shall be binding upon the successors and assigns of Entropic. Employee
shall not be entitled to assign any of his rights or obligations under this Agreement, other than to his or her estate as provided in section 1.7. 
 5.3 Applicable Law. This Agreement shall be interpreted, construed, governed and enforced in accordance with the laws of the United States of America and the State of California. Each of the
parties irrevocably consents to the exclusive jurisdiction of the federal and state courts located in San Diego, California, as applicable, for any matter arising out of or relating to this Agreement. 

5.4 Amendments. No amendment or modification of the terms or conditions of this Agreement shall be valid unless in subsequent
writing and signed by the parties thereto. 
 5.5 Headings. Section headings are for convenience only and shall be given
no effect in the construction or interpretation of this Agreement. 
 5.6 Notice. All notices made pursuant to this
Agreement, shall be given in writing, delivered by a generally recognized overnight express delivery service, and shall be made to the principal place of business of Entropic or to Employee’s residence, as applicable. 

 5.7 Entry Into This Agreement. This Agreement may be entered into by facsimile and in
counterparts, all of which taken together shall be one agreement. 
 IN WITNESS
WHEREOF, the parties hereto execute this Agreement, effective as of the Effective Date.

Rate
Margin	 
	 Percentage Outstanding

	 above 35% to 65%
	  	 	2.50	%

Lender: (a) commercial credit cards, (b) stored value cards, and (c) treasury management services (including, without limitation, controlled disbursement, automated clearinghouse transactions, return items, overdrafts and interstate
depository network services). 
 “Banking Services Obligations” of the Borrower shall mean any
and all obligations of the Borrower owing to any Lender, whether absolute or contingent and howsoever and whensoever created, 

  
 -4-

 
arising, evidenced or acquired (including all renewals, extensions and modifications thereof and substitutions therefor) in connection with Banking Services. 

“Base Rate” shall mean, for any day, an interest rate per annum equal to the greatest of
(a) the Prime Rate in effect on such day plus the Applicable Prime Rate Margin in effect on such day, (b) the Federal Funds Rate in effect on such day plus one-half of one percent (0.5%) plus the Applicable LIBO Rate
Margin in effect on such day, and (c) the LIBO Rate on such day for a one month Interest Period commencing on such day (or if such day is not a Business Day, the immediately preceding Business Day), provided that if during any calendar
month the Base Rate becomes determined under either clause (b) or clause (c) above, then (notwithstanding any language in Section 2.1(b) to the contrary) the Base Rate for the remainder of that calendar month shall continue to
be determined using solely that clause until the first Business Day of the next calendar month. For the avoidance of doubt, for purposes of this definition, LIBO Rate for any day shall be determined in accordance with the definition thereof but
using the rate per annum as determined by the Agent on such day using the referenced information page’s information appearing on such day and time. Without notice to the Borrower or any other Person, the Base Rate shall change automatically
from time to time as and in the amount by which the Prime Rate, the Federal Funds Rate or the LIBO Rate shall fluctuate, subject to the limiting proviso stated above in this definition, with each such change in the Base Rate to be effective as of
(and including) the date of such change in the Prime Rate, the Federal Funds Rate or the LIBO Rate, respectively. If, however, the Agent determines on any day that no LIBO Rate bid rate is quoted to the Agent (or otherwise that adequate and
reasonable methods do not exist for ascertaining the LIBO Rate) for a one month Interest Period for purposes of determining the interest rate on the Base Rate Advances on any day, then the Base Rate Advances shall bear interest at the greater
of (x) the Prime Rate in effect on such day plus the Applicable Prime Rate Margin (as defined below) in effect on such day and (y) the Federal Funds Rate in effect on such day plus one-half of one percent (0.5%) plus
the Applicable LIBO Rate Margin in effect on such day, until the Agent determines that LIBO Rate bid rates are being provided. The Base Rate shall remain fixed for one Business Day, to be adjusted on a daily basis to reflect any changes in the Prime
Rate, the Federal Funds Rate, or the LIBO Rate, as applicable, and further adjusted on a daily basis to reflect any changes in the Applicable Prime Rate Margin or the Applicable LIBO Rate Margin, as applicable.

  
 -5-

 “Borrowing Base” shall mean, at any time, the dollar amount
calculated as the maximum loan value of the Collateral as determined by the Agent, in each case with the consent of the Required Lenders or all the Lenders, as applicable, as provided below in this definition, in their sole discretion, but based
upon their respective customary standards and practices from time to time in effect with respect to secured oil and gas property lines of credit in determining the discounted present value of the Collateral’s production and the Borrower’s
cash flows. Any good faith determination by the Agent and the Lenders of the Borrowing Base shall be final and conclusive as to the Borrower. The Borrowing Base may be revised by Agent and the Lenders at any time to reflect changes in the Collateral
or the occurrence of events or economic conditions or otherwise pursuant to Agent’s and the Lenders’ customary standards and practices as such exist at that particular time, and further will be subject to scheduled semi-annual
redeterminations (approximately April 1 and October 1) during the term of this Loan, commencing October 1, 2011. Additionally, the Borrower may request once per any six month period between scheduled redeterminations that an
unscheduled redetermination be done by Agent and the Lenders, subject to Borrower’s payment to Agent for distribution to the Lenders of a fee in accordance with Section 2.5. The Agent shall notify the Borrower of the result of each
Borrowing Base redetermination and its effective date (which shall not be retroactive without the Borrower’s written consent). Each determination of the Borrowing Base shall be effective until redetermined by the Agent in accordance with this
Agreement (or until the Maturity Date). Such redetermination may lead to increased or decreased credit availability to the Borrower under the revised Borrowing Base schedule, and any increase shall be subject to Lenders’ credit approval
process. The Borrowing Base after any redetermination may be subject to automatic Periodic Reductions (with notice to Borrower) as provided and defined in Subsection 2.4 (c). Without limiting the foregoing, the Agent may exclude, in its sole
and absolute discretion, any property or portion of production therefrom from the Borrowing Base, at any time, because title information on, or the status of title to, such property is not reasonably satisfactory to Agent, such property is not
Collateral, the Agent’s Lien therein is not first and prior to all others, such property is subject to contractual agreements or commitments not reasonably satisfactory to Agent, or such property is not assignable. The Borrower acknowledges
that the determination of the Borrowing Base contains an equity cushion (market value in excess of loan value), which is acknowledged by the Borrower to 

  
 -6-

 
be essential for the adequate protection of the Agent and the Lenders. On the Closing Date, the Borrowing Base is $60,000,000.00. Thereafter, the Agent shall make a
preliminary redetermination of the Borrowing Base each March 15 and September 15 of each year (assuming timely delivery of requested information from the Borrower, including under Subsection 5.2(c) below), and otherwise at
such times as deemed appropriate by the Agent or the Required Lenders (including as may be provided by Section 3.3). The Agent promptly shall notify the Lenders in writing of each such preliminary redetermination. Each Lender shall
notify the Agent in writing of either its approval or disapproval of any such preliminary redetermination of the Borrowing Base within ten (10) Business Days after its receipt of such notice. Each re-determination of the Borrowing Base which
results in an increase shall require the consent of all of the Lenders; each other redetermination of the Borrowing Base (which results in no change or a decrease, including pursuant to Subsection 6.8(b) below) shall require the consent of
the Required Lenders. Upon approval of all the Lenders or the Required Lenders, as applicable, of each redetermination, the Agent shall notify the Borrower as provided above. 

“Business Day” shall mean (a) for all purposes other than as covered by clause (b) of this
definition, a day other than a Saturday, Sunday or legal holiday for commercial lenders in either New Orleans, Louisiana, or New York, New York, and (b) with respect to all requests, notices and determinations in connection with LIBO Rate
Loans, a day which is a Business Day described in clause (a) of this definition and which is a day for trading by and between lenders for dollar deposits in the London interbank market.

Lenders and all the other conditions in Section 7.1 and in Section 11.4 are met or waived (temporarily or otherwise).

documents from time to time required by the Agent and the Lenders to obtain the security interest in the Collateral, or otherwise guarantee or secure the Secured Liabilities, or otherwise pertaining to this Agreement (including without limitation

 “Commitment Limit” shall mean, at any particular date, the lesser of (a) the
Amount (as it may be increased by the Lenders from time to time) or (b) the Borrowing Base as most recently determined and in effect (including the effect of any Periodic Reductions), provided, however, that when a Defaulting

and warranties contained in this Agreement, on the Closing Date each Lender, severally, agrees to make a revolving line of credit available to the Borrower in the maximum aggregate principal

Interest Period for each LIBO Rate Advance. Interest on (i) Base Rate Advances and all other Indebtedness except for LIBO Rate Advances shall be calculated on the basis of a 365 (or in a leap year 366) day year and the actual number of days
elapsed, and (ii) on LIBO Rate Advances shall be calculated on the basis of a 360-day year by applying the ratio of the annual interest rate over a year of 360 days, times the applicable principal balance, times the actual number of days such
applicable principal balance is outstanding. Payments may be debited from the Borrower’s accounts with the Agent as provided in this Agreement. The Maximum Rate shall be calculated based on a 365-day or 366-day year, as is applicable.

 (c) Draw Requests. In accordance with the provisions in this Section, the Lenders will
make Advances to the Borrower from time to time on any Business Day on and after the Closing Date until and including the last Business Day before the Maturity Date in such amounts as the Borrower may request in accordance with this
Section 2.1, up to the Commitment Limit, and the Borrower may make borrowings, repayments and reborrowings in respect thereof. Each Advance (whether a LIBO Rate Advance or a Base Rate Advance) shall be in a minimum amount of $250,000.00
and integral multiples of $250,000.00 in excess of that minimum amount. 

  
 -25-

 
Requests for Advances in substantially the form of Exhibit C (or other writing acceptable to the Agent) must be made by written notice from the Borrower sent to the Agent by mail, courier
or facsimile in accordance with Section 10.1, specifying the amount of the Advance, subject to Section 2.12. A request shall be fully authorized by the Borrower if made by any one of James Merrill or Ken Kenworthy Jr. or
other individual designated by the Borrower as an authorized person in accordance with resolutions of the Board of Directors of the Borrower certified to the Agent. The Agent and the Lenders may rely fully and completely upon the authority of the
signatory of such request or confirmation unless such authority is terminated by written notice to the Agent, and any such termination shall be effective only prospectively. The request for any Advance by the Borrower shall constitute a
certification by the Borrower that all of the representations and warranties contained in Article 4 (other than those representations and warranties, if any, that are by their specific terms limited in application to a specific date) are true
and correct as of the date of such request and also as of the date of the Advance. 
 (d)
Timing. Requests for Advances at the Base Rate shall be made on written notice from the Borrower to the Agent, received by the Agent no later than 10:00 a.m. (Central Time) on the Business Day of such Base Rate Advance specifying the amount
thereof. Request for Advances at the LIBO Rate shall be made on written notice from the Borrower to the Agent received by the Agent no later than 11:00 a.m. (Central Time) on the third (3rd) Business Day before such LIBO Rate Advance,
specifying the amount thereof (including the amount of each tranche, if more than one) and the LIBO Rate Interest Period (or Interest Periods, if more than one tranche). Each such written notice by the Borrower shall be irrevocable by the Borrower.
The Agent shall promptly give each Lender notice of such proposed Advance. 
 (e) Funding.
Not later than 12:00 noon (Central Time) on the date of any Advance, each of the Lenders shall make available to the Agent, in immediately available funds, the amount of such Lender’s prorata portion (i.e., the percentage of its Commitment as
compared to the aggregate of the Commitments) of the amount of the requested Advance. Upon receipt from each Lender of such amount, and upon fulfillment of the applicable conditions set forth in this Agreement in Article 7, the Agent (on
behalf of the Lenders) will make available to the Borrower the aggregate amount of such Advance in accordance with the further terms of this Section 2.1. The failure or refusal of any Lender to make available to the Agent at the
aforesaid time and place on any date of an Advance the amount of its portion of the requested Advance shall not relieve any other Lender from its several obligation hereunder to make available to the Agent the amount of such other Lender’s
portion of any requested Advance (but no Lender shall be responsible for the failure of any Lender to make available to the Agent such other Lender’s portion of any requested Advance). 

The Agent may, unless notified to the contrary by any Lender prior to the date of an Advance, assume that
each Lender has made available to the Agent on such date of the applicable Advance the amount of each Lender’s portion of the Advance to be made on such date, and the Agent shall, in reliance upon such assumption, make available to Borrower a
corresponding amount. If any Lender makes available to the Agent such amount on a date after the date of the applicable Advance, such Lender shall pay to the Agent on demand an amount equal to the product of (i) the average computed for the
period referred to in clause (iii) below, of the weighted average interest rate paid by the Agent for federal funds acquired by the Agent 

  
 -26-

 
during each day included in such period, times (ii) the amount of such Lender’s portion of such Advance, times (iii) a fraction, the numerator of which is the number of days that
elapse from and including such date of the Advance to the date on which the amount of such Lender’s portion of such Advance shall become immediately available to the Agent, and the denominator of which is 365; provided, that if such Lender has
not paid to the Agent such Lender’s portion of the Advance by 12:00 noon (Central Time) on the third (3rd) Business Day after the Advance was made to the Borrower, then the interest rate in clause (i) above shall be the Prime Rate
(adjusted daily) from and after such second
(2nd) Business Day after the Advance was made until
and including the date such Lender makes available to the Agent such Lender’s portion of the Advance; provided, further, that if such Lender has not paid to the Agent such Lender’s portion of the Advance by 12:00 noon (Central Time) on the
fifth (5th) Business Day after the Advance was made to Borrower, then the interest rate in clause (i) above shall be the Prime Rate (adjusted daily) plus three (3.0%) percent per annum from and after such fifth (5th) Business Day after the Advance was made until and including
the date such Lender makes available to the Agent such Lender’s portion of the Advance. A statement of the Agent submitted to each Lender with respect to any amounts owing under this paragraph shall be prima facie evidence of the amount due and
owing to the Agent by such Lender. If any Lender fails to pay to Agent its portion of any Advance within fifteen (15) days after an Advance or if any Lender twice fails to timely make its portion of Advances to be made to the Borrower available
to the Agent before 12:00 noon (Central Time) on the dates Advances are made to the Borrower (counting failures in reimbursement under Subsection 2.1(g) as a failure hereunder), then, if requested to do so by the Borrower or any other Lender
or the Agent, such Lender shall sell all of its interests, rights and obligations under this Agreement (including all of its Commitment and its portion of the Loan at the time owing to it) and the Note held by it to another Lender or lender under
Section 9.6 hereof, provided such a willing, qualified assignee is identified by the requesting party. Such Defaulting Lender shall make such sale in accordance with the provisions of Section 9.6. 

Not later than 3:00 p.m. (Central Time) on the date properly and timely requested for the Advance and upon
fulfillment of the applicable conditions set forth in Article 7 of this Agreement, the Agent will make such Advance available to the Borrower in same day funds in the account maintained by the Borrower with the Agent and the credit advice resulting
therefrom shall be mailed by the Agent to the Borrower. The Borrower irrevocably agrees that the deposit of the proceeds of any Advance in any account of Borrower with the Agent, or the Agent’s copy of any cashier’s check representing all
or any part of the proceeds of the disbursements, shall be deemed prima facie evidence of the Borrower’s Indebtedness to the Lenders under the Loan. 

(f) Minimum. Notwithstanding anything in this Agreement to the contrary, the aggregate principal
amount of all LIBO Rate Advances having the same LIBO Rate Interest Period shall be at least equal to $250,000.00; and if any LIBO Rate tranche would otherwise be in a lesser principal amount for any period, such tranche shall bear interest at the
Base Rate during such period. 
 (g) Letters of Credit. As a portion of the line of credit
availability up to the Letter of Credit Sublimit (and subject to the Borrowing Base and the other terms and conditions contained in this Agreement), the Issuing Bank will issue standby letters of credit for the account of the Borrower (including for
the commercial needs of any one or more of the Borrower’s 

  
 -27-

 
wholly-owned Subsidiaries from time to time in existence, so long as such entity is wholly owned directly or indirectly) from time to time. The expiration of such letters of credit shall be on a
Business Day not later than one year after issuance, and further shall not extend beyond the Maturity Date of the line of credit. The expiration date of a letter of credit may not be extended on or after the Maturity Date and no letter of credit may
be renewed, replaced or increased on or after the Maturity Date. The Borrower shall pay to the Agent, for disbursement to the Lenders in accordance with Subsection 9.1(a), a fee for each standby letter of credit at the per annum rate equal to
the Applicable LIBO Rate Margin then in effect on the maximum amount available to be drawn under the letter of credit for the period from the date of issuance to its expiration date, payable quarterly in arrears on each
June 30, September 30, December 31 and March 31 (and on the Maturity Date). In addition, the Borrower shall pay the Agent as a fronting fee, which the Agent shall retain for its own account as letter of credit Issuing
Bank, one-quarter of one percent (0.25%) on the face amount. The Borrower also shall pay to the Agent, for the account solely of the Issuing Bank, additional amounts customarily charged by the Issuing Bank for the issuance and processing of letters
of credit. Each letter of credit shall be issued not later than the close of the Issuing Bank’s business (Central Time) on the third (3rd) Business Day after receipt (including by facsimile pursuant to Section 10.1 hereof) by
the Issuing Bank of the Borrower’s written application in substantially the form of the Issuing Bank’s then standard Application for Irrevocable Standby Letter of Credit and Letter of Credit Agreement, executed by the Borrower (by any one
of the persons designated by the Borrower in writing to the Agent in accordance with the terms of Subsection 2.1(d) below). Such application and agreement shall be Collateral Documents under this Agreement, supplemental to and not in
replacement of this Agreement and the other Collateral Documents, provided that in the event of a conflict between such application and agreement and this Agreement then this Agreement shall prevail (even if such application or agreement is executed
later). In the event such written application is telecopied to the Issuing Bank, the Issuing Bank may but need not confirm such application before acting thereupon. The Issuing Bank may rely fully and completely upon the authority of the signatory
of such written application and the contents thereof unless such authority is terminated by written notice to the Issuing Bank, and any such termination of authority shall be effective only prospectively. Such letters of credit will be documented on
the Issuing Bank’s standard forms. No letter of credit will be issued (x) if the face amount thereof plus the aggregate Letter of Credit Usage then outstanding would exceed the Letter of Credit Sublimit, or (y) if the face amount
thereof plus the aggregate Letter of Credit Usage then outstanding plus the aggregate of all Advances then outstanding would exceed the Commitment Limit. Payment by the Issuing Bank of a draw on a standby letter of credit, if not reimbursed in full
on the same day by the Borrower, automatically (notwithstanding the limitation in Subsection 2.1(a) above) shall be an Advance as a part of the Loan bearing interest from the date of such draw at the Base Rate. Upon its issuance of any such
letter of credit, the Issuing Bank shall promptly notify each other Lender of such issuance. Immediately upon the issuance by the Issuing Bank of any letter of credit, the Issuing Bank shall be deemed to have sold and transferred to each other
Lender and each such other Lender shall be deemed irrevocably and unconditionally to have purchased and received from the Issuing Bank, without recourse or warranty, an undivided interest and participation in such letter of credit, each drawing made
thereunder and the obligations of the Borrower under this Agreement with respect thereto, and any security therefor or guaranty pertaining thereto. The amount of such other 

  
 -28-

 
Lender’s participation shall be such other Lender’s prorata portion (i.e., such Lender’s Commitment as compared to the aggregate of the Commitments). 

In the event that the Issuing Bank makes any payment under any letter of credit and the Borrower shall not
have reimbursed such amount in full to the Issuing Bank on the date of such payment, the Issuing Bank shall promptly notify the Agent, which shall promptly notify each other Lender of such failure, and each other Lender shall promptly and
unconditionally pay to the Issuing Bank the amount of such other Lender’s prorata portion (i.e., such Lender’s Commitment as compared to the aggregate of the Commitments) of such unreimbursed payment in immediately available funds. If the
Agent so notifies, prior to 11:00 a.m. (Central Time) on any Business Day, each Lender shall make such payment on such Business Day. The failure or refusal by any Lender to make reimbursement to the Issuing Bank at the aforesaid time and place in
the amount of its portion of such reimbursement shall not relieve any other Lender from its several obligation hereunder to make reimbursement to the Issuing Bank in the amount of such other Lender’s portion of such requested reimbursement (but
no Lender shall be responsible for the failure of any Lender to make reimbursement to the Issuing Bank of such other Lender’s portion of such requested reimbursement). If any Lender makes reimbursement to the Issuing Bank of such amount on a
date after the aforesaid date for reimbursement, such Lender shall pay to the Issuing Bank on demand an amount computed on the basis set forth in Subsection 2.1(e) above (substituting such reimbursement due date for the Advance Date), which
Subsection 2.1(e) shall be fully applicable to such failure. 
 The obligations of the
other Lenders to make reimbursement payments to the Issuing Bank with respect to letters of credit issued by it shall be irrevocable and not subject to any qualification or exception whatsoever. In determining whether to pay under any letter of
credit, the Issuing Bank shall have no obligation relative to the other Lenders other than to confirm that any documents required to be delivered under such Letter of Credit appear to have been delivered and that they appear to comply on their face
with the requirements of such letter of credit. Any action taken or omitted to be taken by the Issuing Bank under or in connection with any letter of credit if taken or omitted in the absence of gross negligence or willful misconduct shall not
create for the Issuing Bank any resulting liability to the Borrower or any Lender. 
 Letters of
credit issued under the Prior Loan Agreement and still outstanding on the Closing Date shall hereafter be counted under and governed by this Agreement. 
 Section 2.2 Business Days. If the date for any payment, prepayment, Periodic Reduction, or fee payment hereunder falls on a day which is not a Business Day, then for all purposes of
this Agreement (unless otherwise provided herein) the same shall be deemed to have fallen on the next following Business Day, and such extension of time shall in such case be included in the computation of payments of interest. 

Section 2.3 Payments. The Borrower shall make each payment hereunder and under the Notes and any Collateral
Documents in lawful money of the United States of America in same day funds to the Agent at its office at 5718 Westheimer, Houston, Texas, not later than 11:00 a.m. (Central Time) on the day when due, or such other place in the United States as

  
 -29-

 
designated in writing by the Agent, without any offset, counterclaim or any other deduction. The Agent shall promptly send to each Lender by federal wire transfer its respective proportionate
share of all amounts to which the Lenders are entitled in accordance with Subsection 9.1(a). The Borrower hereby authorizes the Agent to charge from time to time against the Borrower’s accounts with the Agent any amount which is then so
due, and acknowledges that such accounts will be established for that purpose (among other purposes) under Section 5.16 and Section 5.17 and may be so used even in the absence of an Event of Default. 

Section 2.4 Prepayment. (a) Voluntary. The Borrower may prepay the Loan in full or in part at any
time without payment of premium or penalty; provided, however, that (i) the Borrower shall give the Agent notice of each such prepayment of all or any portion of a LIBO Rate Advance no less than three (3) Business Days prior to prepayment,
(ii) any LIBO Rate Advance may be prepaid only on the last day of the Interest Period for such LIBO Rate Advance, unless the Borrower includes payment of amounts, if any, required to be paid pursuant to paragraph 6 of Addendum I,
(iii) the Borrower shall give the Agent notice of each such prepayment of all or any portion of a Base Rate Advance no later than 10:00 a.m. (Central Time) on the Business Day of such prepayment, (iv) the Borrower shall pay all accrued and
unpaid interest on the amounts prepaid, and (v) no such prepayment shall serve to postpone the repayment when due of any other Indebtedness. Each such notice of a prepayment under this Section shall be irrevocable and the amounts specified in
each such notice shall be due and payable on the date specified. Upon receipt of such notice, the Agent shall promptly notify each Lender thereof. Each partial prepayment shall be in an aggregate principal amount of (x) $250,000.00 or an
integral multiple of $250,000.00 in excess thereof or (y) if the outstanding principal balance of the Loan is less than the minimum amount set forth in the preceding clause (x) of this sentence, then such lesser outstanding principal
balance, as the case may be. 
 (b) Mandatory. The Agent shall notify the Borrower of the
result of each Borrowing Base redetermination in accordance herewith. If at any time the Agent determines that a Loan Excess exists, then within ten (10) days after being notified of the Loan Excess the Borrower shall indicate by written notice
to the Agent of its decision to do one or a combination of the following actions within ninety (90) days of receipt by the Borrower of notice of such Loan Excess (and, thereafter, in compliance with such notice the Borrower shall):
(x) prepay the Advances (together with accrued interest on the amount to be prepaid to the date of payment) in an amount sufficient to reduce the Advances plus the face amount of all standby letters of credit then outstanding to the then
Commitment Limit, and/or (y) execute, deliver and record or cause to be executed and delivered such additional Collateral Documents pursuant to Section 3.1, sufficient to induce the Agent and the Lenders to make an increased
redetermination of the Borrowing Base to an amount not less than the outstanding principal balance of the Advances plus the face amount of all standby letters of credit then outstanding. The Borrower specifically acknowledges that no additional
grace period (beyond the period stated in the preceding sentence) is applicable under this Agreement to any failure to make such mandatory prepayment before such failure is an Event of Default hereunder. 

(c) Periodic Reductions in Borrowing Base. As part of a Borrowing Base redetermination, the Agent
may include as part of the Borrowing Base an automatic reduction schedule, monthly or quarterly, in an amount determined by the Agent in its sole discretion, but 

  
 -30-

 
based upon the Agent’s customary standards and practices from time to time in effect with respect to secured oil and gas property lines of credit, and with the approval of the Required
Lenders. Such automatic reductions, each in the amounts so determined and so scheduled (each a “Periodic Reduction”), shall cause an automatic reduction to the Borrowing Base on the dates set in the schedule so determined by the
Agent, which shall be the last day of a month or quarter. Each reduction to the Borrowing Base by a Periodic Reduction shall be permanent, subject to any increase agreed to as part of a subsequent Borrowing Base redetermination. As part of the
notification by the Agent to the Borrower of the result of a Borrowing Base redetermination, the Agent shall notify the Borrower of the terms and schedule of any Periodic Reductions included therein. Notwithstanding the foregoing provisions of
Subsection 2.4(b), the Borrower shall pay the amount of any Loan Excess that results from the application of each Periodic Reduction to the Borrowing Base on the day that such Periodic Reduction takes effect. The Borrower specifically
acknowledges that the ninety (90) day grace period set forth in Subsection 2.4(b) pertaining to a Loan Excess resulting from a Borrowing Base redetermination is not applicable to any failure to make such mandatory prepayment triggered by
a Loan Excess due to a Periodic Reduction as provided in this Subsection 2.4(c). However, any changes in the Periodic Reduction schedule shall not increase the amount of a Periodic Reduction which is to take effect sooner than ninety
(90) days after the effective date of that Borrowing Base redetermination which includes such change in the Periodic Reduction schedule as a part thereof. On the Closing Date no Periodic Reduction is in effect, subject to change as part
of a subsequent Borrowing Base redetermination. 
 Section 2.5 Fees. (a) Reserved.

 (b) The Borrower shall pay the Agent, for disbursement in accordance with Subsection
9.1(a) hereof to the Lenders, an unused facility fee quarterly in arrears beginning March 31, 2011 (for the period from the Closing Date through such date) and on the last day of each succeeding March, June, September and December and on
the Maturity Date of the Loan, in an amount equal to one-half of one percent (0.50%) per annum on (x) the Commitment Limit less (y) the average outstanding aggregate principal balance of the Advances under the Notes plus the undisbursed
amount of all standby letters of credit then outstanding during such quarter (or lesser time period, as applicable.) 
 (c) Letter of credit fees are owed and paid as provided in Subsection 2.1(g). 
 (d) The Borrower shall pay to the Agent, for its own account, such fees as are agreed to in a separate agreement between the Borrower and the Agent with respect to the Agent’s services provided
hereunder and in connection herewith. 
 (e) The Borrower shall pay the Agent, for disbursement
to the Lenders (equally, not pro rata), a Borrowing Base redetermination fee in the amount equal to $7,500.00 for each Lender for each unscheduled redetermination requested by the Borrower at the time of such request. (For the avoidance of doubt,
the Agent receives one fee under this subsection in its capacity as a Lender, but not as Agent.) 

  
 -31-

 (f) The Borrower acknowledges that any subsequent increases
in the Commitment Limit after the Closing Date (which will require the Borrower’s and the Lenders’ unanimous mutual agreement), or any further syndication of the Loan and the joinder of an additional Lender (which will require the consents
specified in Section 9.6), in each case shall be subject to the payment of an appropriate upfront commitment fee, determined by the Lenders in the case of an increase in the Commitment Limit on the incremental increased portion of the
new Commitment Limit in excess of its previous highest level on which an upfront fee was paid, and in the case of further syndication determined by the Agent consistent with the Commitment Letter dated January 26, 2011. 

(g) All fees shall be paid on the dates due in immediately available funds. Fees paid shall not be
refundable under any circumstances. 
 (h) Notwithstanding any provision in this
Section 2.5 to the contrary, the payment of fees under Subsections 2.5(b), (c) and (e) shall be subject to the provisions of Section 2.15. 

Section 2.6 Use of Proceeds. The Borrower shall use the proceeds of the Loan in connection with the
acquisition and development of oil and gas properties as well as general corporate and working capital purposes (including letters of credit hereunder). 
 Section 2.7 Default Rate. Anything in the Notes or in any other agreement, document or instrument to the contrary notwithstanding, effective upon an Event of Default or upon the Maturity Date,
the Agent and the Required Lenders shall have the right to prospectively increase the interest rate under the Notes to the Default Rate until the Notes are paid in full. Upon the acceleration of the principal amount of the Indebtedness represented
by the Notes, the accelerated principal balance of the Loan shall bear interest from the date of acceleration up to the actual payment (as well after as before judgment) at the Default Rate. All such interest at the Default Rate shall be payable
upon demand. 
 Section 2.8 Additional Regulatory Costs. If any governmental authority, central
bank, or other comparable authority shall at any time impose, modify or deem applicable any reserve (including without limitation any imposed by the Board of Governors of the Federal Reserve System), special deposit or similar requirement against
assets of, deposits with or for the account of, or credit extended by, the Agent or any Lender, or shall impose on the Agent or any Lender any other condition affecting an Advance or the obligation of the Agent or any Lender to make an Advance; and
the result of any of the foregoing is to increase the cost to the Agent or such Lender of making or maintaining the Advances to the Borrower, or to reduce the amount of any sum received or receivable by the Agent or any Lender under this Agreement
or under the Notes by an amount deemed by the Agent or such Lender to be material, then, within sixty (60) days after demand by the Agent or such Lender, the Borrower shall pay to the Agent or such Lender, for its own account, such additional
amount or amounts as will compensate the Agent or such Lender for such increased cost or reduction. The Agent or such Lender will promptly notify the Borrower of any event of which it has knowledge, occurring after the date hereof, which will
entitle the Agent or such Lender to compensation pursuant to this Section. A certificate of the 

  
 -32-

 
Agent or such Lender claiming compensation under this Section and setting forth the additional amount or amounts to be paid to it hereunder shall be conclusive in the absence of manifest error.

 Section 2.9 Application of Payments to Indebtedness. Payments made under this Agreement, the
Notes or the Collateral Documents, whether made when due or after foreclosure on Collateral, for application to the Indebtedness shall be applied to the Indebtedness as follows: 

(i) To the Agent, with respect to fees and expenses accrued and outstanding (including without limitation reasonable
attorneys’ fees and expenses); 
 (ii) To the Lenders, ratably according to their Commitments, with respect
to fees, expenses and late charges accrued and outstanding; 
 (iii) To the Lenders, ratably according to their
Commitments, with respect to interest accrued and outstanding; and 
 (iv) To the Lenders, ratably according to
their Commitments, with respect to principal amounts of the Loan due and payable. 
 Payments made pursuant to realization under
the Collateral Documents are also subject to the Section 3.4. Notwithstanding any provision of this Section 2.9 to the contrary, if any Lender becomes a Defaulting Lender, then the provisions of Section 2.15 shall
apply for so long as such Lender is a Defaulting Lender. 
 Section 2.10 Sharing of Payments among
Lenders. If any Lender, whether by setoff or otherwise, has payment made to it upon its portion of the Loan, other than pursuant to Section 2.8 or Addendum 1, in a greater proportion than that received by any other Lender,
such Lender agrees, promptly upon demand, to purchase a portion of the Loan held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of the Loan. If any Lender, whether in connection with setoff or amounts
which might be subject to setoff or otherwise, receives collateral or other protection for its Indebtedness or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders
share in the benefits of such Collateral ratable in proportion to their Commitment. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustment shall be made. However, nothing in this Section 2.10
is intended, or shall be construed, to amend the provisions of or alter the application of Section 3.4. Notwithstanding any provision of this Section 2.10 to the contrary, if any Lender becomes a Defaulting Lender, then the
provisions of Section 2.15 shall apply for so long as such Lender is a Defaulting Lender. 

Section 2.11 Hedge Agreement Quotes. Upon the Borrower’s request from time to time, the Agent will
provide to Borrower interest rate swap quotes for interest rate Hedge Agreements pertaining to the Loan, not to exceed the Commitment Limit or the Maturity Date. 

Section 2.12 Telephonic or Electronic Notice to Agent. Without in any way limiting the obligation of the
Borrower to confirm in writing any telephonic notice of borrowing or the like given to the Agent, the Agent may act without liability upon the basis of telephonic notice of such request believed by the Agent in good faith to be from an authorized
officer of the Borrower 

  
 -33-

 
prior to receipt of written confirmation. In each such case, the Agent’s records with regard to any such telephone notice shall be presumptive correct, absent manifest error. Additionally,
the Borrower may transmit notices of borrowing or letter of credit requests or the like by electronic communication, if arrangements for doing so have been approved by the Agent. 

Section 2.13 Lost Interest Recapture; Usury Savings. (i) If, with respect to the Lenders, the effective
rate of interest contracted for under this Agreement, the Notes and the Collateral Documents (the “Loan Documents”), including the stated rates of interest and fees contracted for hereunder and any other amounts contracted for under
the Loan Documents which are deemed to be interest, at any time exceeds the Maximum Rate, then the outstanding principal amount of the loans made by the Lenders hereunder shall bear interest at a rate which would make the effective rate of interest
for the Lenders under the Loan Documents equal the Maximum Rate until the difference between the amounts which would have been due at the stated rates and the amounts which were due at the Maximum Rate (the “Lost Interest”) has been
recaptured by the Lenders. 
 (ii) If, when the loans made hereunder are repaid in full, the Lost
Interest has not been fully recaptured by a Lender pursuant to the preceding paragraph, then, to the extent permitted by law, for the loans made hereunder by such Lender the interest rates charged under Section 2.1 hereunder shall be
retroactively increased such that the effective rate of interest under the Loan Documents was at the Maximum Rate since the effectiveness of this Agreement to the extent necessary to recapture the Lost Interest not recaptured pursuant to the
preceding sentence and, to the extent allowed by law, the Borrower shall pay to such Lender the amount of the Lost Interest remaining to be recaptured by such Lender. 

(iii) NOTWITHSTANDING THE FOREGOING OR ANY OTHER TERM IN THIS AGREEMENT AND THE LOAN DOCUMENTS TO THE
CONTRARY, IT IS THE INTENTION OF THE LENDERS AND THE BORROWER TO CONFORM STRICTLY TO ANY APPLICABLE USURY LAWS. ACCORDINGLY, IF A LENDER CONTRACTS FOR, CHARGES, OR RECEIVES (INCLUDING WITHOUT LIMITATION FOLLOWING ACCELERATION OR PREPAYMENT)
ANY CONSIDERATION WHICH CONSTITUTES INTEREST IN EXCESS OF THE MAXIMUM RATE, THEN ANY SUCH EXCESS SHALL BE CANCELED AUTOMATICALLY WITHOUT THE NECESSITY OF THE EXECUTION OF ANY NEW DOCUMENT AND, IF PREVIOUSLY PAID, SHALL AT SUCH LENDER’S OPTION
BE APPLIED TO THE OUTSTANDING AMOUNT OF THE LOAN MADE HEREUNDER BY SUCH LENDER OR BE REFUNDED TO THE BORROWER. 
 (iv) All sums paid or agreed to be paid to Lenders for the use, forbearance or detention of the Indebtedness shall, to the extent permitted by applicable law, be amortized, prorated, allocated and spread
throughout the full term of the Indebtedness until payment in full so that the rate or amount of interest on account of the Indebtedness does not exceed the applicable usury limit allowed by applicable law through the full term hereof. 

  
 -34-

 Section 2.14 Business Loans. The Borrower warrants and
represents that the Loan and Advances evidenced by the Notes are and shall be for business, commercial, investment, or other similar purposes and not primarily for personal, family, household, or agricultural use, as such terms are used in Chapter
306 of the Texas Finance Code. At all such times, if any, as Chapter 303 of the Texas Finance Code shall establish a Maximum Rate, the Maximum Rate shall be determined in accordance with Chapter 303 of the Texas Finance Code based on the
“weekly ceiling” (as such term is defined in Chapter 303 of the Texas Finance Code) from time to time in effect. 
 Section 2.15 Defaulting Lender. Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so
long as such Lender is a Defaulting Lender: 
 (a) Any amount payable to such Defaulting Lender
hereunder (whether on account of principal, interest, fees or otherwise, and including any amount that would otherwise be payable to such Defaulting Lender pursuant to Section 2.9, Section 2.10, Section 3.4 and
Section 9.1), except excluding Subsection 2.1(e) and Section 9.6, shall, in lieu of being distributed to such Defaulting Lender, be retained by the Agent in a segregated account and be applied at such time or times as
may be determined by the Agent (i) first, to the payment of any amounts owing by such Defaulting Lender to the Agent hereunder, (ii) second, to the payment of any amounts owing by such Defaulting Lender to the Issuing Bank
hereunder, (iii) third, to the funding of any Advance under the Loan or the funding or cash collateralization of any participating interest in any letter of credit in respect of which such Defaulting Lender has failed to fund its
reimbursement portion thereof as required by this Agreement, (iv) fourth, if so determined by the Agent and the Borrower, held in such account as cash collateral for future funding obligations of the Defaulting Lender under this
Agreement, (v), fifth, pro rata, to the payment of any amounts owing to the Borrower or the Lenders as a result of any judgment of a court of competent jurisdiction obtained by the Borrower or any Lender against such Defaulting Lender as a
result of such Defaulting Lender’s breach of its obligations under this Agreement, and (vi) sixth, to such Defaulting Lender or as otherwise directed by a court of competent jurisdiction; provided that if such payment is a
prepayment of the principal amount of the Loan or is a reimbursement payment in respect of payments under any letter of credit in either case which a Defaulting Lender has not funded its participation obligations, the Defaulting Lender shall be
subordinated and such payment shall be applied solely to prepay the Outstandings of (including the Advances of and the letter of credit reimbursement obligations owed to) all non-Defaulting Lenders pro rata before being applied to the
prepayment of any Outstandings of (whether Advances by or letter of credit reimbursement obligations owed to) any Defaulting Lender, until all Advances and all letter of credit reimbursements of which the Defaulting Lender did not fund its portion
are paid and the Loan is reduced to the level at which the Defaulting Lender had ceased to fund. 

(b) Fees shall cease to accrue on the unfunded portion of the Commitment of such Defaulting Lender
pursuant to Subsection 2.5(b). Further, a Borrowing Base redetermination fee under Subsection 2.5(e) shall cease to be owing to such Defaulting Lender. Letter of credit fees under Subsection 2.5(c) shall be handled as provided
in Subsection 2.15(c). 

  
 -35-

 (c) If any Letter of Credit Usage exists at the time a
Lender becomes a Defaulting Lender, then, if the conditions set forth in Section 7.4 are satisfied at such time: 
 (i) The Letter of Credit Usage shall be reallocated among the non-Defaulting Lenders, after disregarding the Defaulting Lender’s Commitment, in proportion with their respective Commitments, but only
to the extent that the sum of all non-Defaulting Lenders’ portions of funded Advances and Letter of Credit Usage does not exceed the total of all the non-Defaulting Lenders’ portions of the Commitment Limit; 

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected,
the Borrower shall within one (1) Business Day following notice by the Agent cash collateralize such Defaulting Lender’s portion of the Letter of Credit Usage (after giving effect to any partial reallocation described in clause
(i) above), with such cash to be held by the Agent as collateral for the payment of such letters of credit, for such long as such Letter of Credit Usage is outstanding; 

(iii) If the Borrower cash collateralizes any portion of such Defaulting Lender’s Letter of Credit
Usage pursuant to this Subsection 2.15(c), the Borrower shall not be required to pay any letter of credit fees to such Defaulting Lender pursuant to Subsection 2.1)(g) with respect to such Defaulting Lender’s portion of the Letter
of Credit Usage during the period such Defaulting Lender’s portion of the Letter of Credit Usage is cash collateralized, and further the Agent and the Borrower may determine under Subsection 2.15(a) to release monies deposited by
Borrower in so cash collateralizing to the extent replaced by funds payable to the Defaulting Lender; 
 (iv) If the reallocation described in clause (i) above is made, then the letter of credit fees payable to the Lenders pursuant to Subsection 2.1(g) shall be adjusted in accordance with such
non-Defaulting Lender’s Commitments (disregarding any Defaulting Lender’s Commitment); 

(v) If any Defaulting Lender’s portion of the Letter of Credit Usage is neither cash collateralized
nor reallocated pursuant to this Subsection 2.15(c), then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, the Issuing Bank shall instead be paid the letter of credit fees that would have been payable
to the Defaulting Lender, and the Issuing Bank shall have the right to payments under Subsection 2.15(a)(ii) above; and 
 (vi) So long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit unless it is satisfied that the related exposure will be 100%
covered by the Commitments of the Non-Defaulting Lenders or cash collateral will be provided by the Borrower in accordance with this Subsection 2.15(c), and participating interests in any such newly issued or increased letter of credit shall
be allocated among non-Defaulting Lenders in a manner consistent with Subsection 2.15(c)(i) (and Defaulting Lenders shall not participate therein). 

(d) The Commitment of such Defaulting Lender shall not be included in determining whether all Lenders or
the Required Lenders have voted or taken or may take any 

  
 -36-

 
action hereunder (including any consent to any amendment or waiver pursuant to Section 10.4), provided that any waiver, amendment or modification requiring the consent of all
Lenders or each affected Lender in either case which affects such Defaulting Lender differently than other affected Lenders, or an increase in the Commitment of such Defaulting Lender, shall require the consent of such Defaulting Lender. 

(e) The Borrower, the Agent or any other Lender may, upon notice to such Defaulting Lender and the Agent,
require such Defaulting Lender to sell all of its interests, rights and obligations under this Agreement and the Note held by it to another Lender or lender in accordance with and subject to the restrictions contained in Section 9.6
hereof, provided such a willing, qualified assignee is identified by the requesting party. 
 (f)
In the event that the Agent, the Borrower and the Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that cause such Lender to be a Defaulting Lender, then the Outstandings shall be readjusted to reflect the
inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Advances of the other Lenders and participations in the letters of credit issued by the Issuing Bank as the Agent may determine may be
necessary in order for such Lender to hold its portion of the Loan in accordance with its pro rata portion of its Commitment to the total Commitments.

Borrowing Base be made directly to the Agent. Such letters shall be held by Agent and not delivered, as provided in Subsection 8.2(c), until the occurrence of an Event of Default. 

(b) The Borrower confirms that the Collateral Documents secure all of the Indebtedness to the Agent and to
each of the Lenders. The Borrower, the Agent and the Lenders acknowledge that the Collateral Documents described in Section 3.1 above secure both such Indebtedness and the Secured Hedge Obligations and the Banking Services Obligations.
The Lenders confirm the application of Section 3.4 to govern the Collateral Documents, the Indebtedness and the Secured Hedge Obligations and the Banking Services Obligations. 

Section 3.2 Confirmation. The Borrower hereby reaffirms its original intention as stated in the Collateral
Documents executed prior to the Closing Date that said existing Collateral Documents secure the Indebtedness as extended and renewed from time to time, including without limitation this Agreement and the Notes executed by the Borrower pursuant to
this Agreement, and all the other Secured Liabilities. The Borrower confirms and agrees that said existing Collateral Documents securing the Secured Liabilities include without limitation the documents described in Section 3.1 above. The
Borrower hereby ratifies and confirms in all respects the existing Collateral Documents executed by it, which remain in full force and effect in accordance with all of their terms, conditions and provisions in favor of the Agent, for the ratable
benefit of the Lenders, and are hereby renewed and carried forward to secure the Indebtedness under this Agreement. To the extent necessary, the Borrower hereby grants anew 

  
 -38-

 
all liens and security interests set forth in such Collateral Documents executed by it to Agent, for the ratable benefit of the Lenders, as security for the Indebtedness. 

Section 3.3 Acquisition Collateral. (a) After each acquisition by the Borrower or any Subsidiary of any
interest in oil, gas and other mineral properties (wherever located, and whether producing or undeveloped) involving an expenditure (in money or property) the total amount of which (whether in one transaction or a series of related transactions)
paid by the Borrower and any Subsidiary to or for the account of any Person in connection with such acquisition exceeds four million ($4,000,000.00) dollars, the Borrower at its expense will promptly, and in no event later than ninety (90) days
after such acquisition, complete the execution and recordation of appropriate Collateral Documents in favor of the Agent, for the ratable benefit of the Secured Parties, and, if requested, the submission of Title Opinions in favor of the Agent
reasonably acceptable to the Agent, covering all such acquired properties. 
 (b) In connection with and at the
time of each redetermination of the Borrowing Base, the Borrower at its expense will promptly, and in no event later than ninety (90) days after such redetermination, complete the execution and recordation of appropriate Collateral Documents in
favor of the Agent, for the ratable benefit of the Secured Parties, covering all rights of way, easements, surface leases or other property rights utilized in the operation of the pipeline and gathering systems which are material to the operation
and sale of the Collateral (including without limitation the production, transportation or marketing of Collateral hydrocarbons). As part of the foregoing requirement, the Borrower shall cause such rights of way and other interests to be recorded in
the appropriate land title records. 
 (c) In connection with and at the time of each redetermination of the
Borrowing Base, the Borrower at its expense will promptly, and in no event later than ninety (90) days after such redetermination, (i) complete the execution and recordation of appropriate Collateral Documents in favor of the Agent, for
the ratable benefit of the Secured Parties, covering any property included within the Borrowing Base which is not already encumbered as Collateral, and (ii) submit title opinions in favor of the Agent reasonably acceptable to the Agent covering
any wells within the Borrowing Base not previously covered by accepted title opinions, provided that clause (ii) is subject to the exception set forth in the following sentence. Upon the Borrower’s request and demonstration of good cause
satisfactory to the Agent and the Required lenders (in their sole and absolute discretion, as part of the process of the Borrowing Base redetermination), a portion of the property within the Borrowing Base may be exempted from this covenant for
acceptable title opinions. The continuing justification for each such exemption shall be reconsidered as part of each redetermination of the Borrowing Base. Nonetheless, the Borrower expressly acknowledges that, as provided in the definition of the
Borrowing Base, the Agent may exclude, in its sole and absolute discretion, any property or portion of production therefrom from the Borrowing Base, at any time, because title information on, or the status of title to, such property is not
reasonably satisfactory to Agent, such property is not Collateral, the Agent’s lien or security interest therein is not first and prior to all others, or such property is not assignable. 

Section 3.4 Sharing among Secured Liabilities. (a) The Agent and the Lenders hereby agree that upon the
foreclosure, sale, set-off or other realization against any of the 

  
 -39-

 
Collateral which secures the Secured Liabilities (and not securing by its terms just the Indebtedness) (the “Shared Collateral”), the Secured Parties shall share in all of the proceeds
of such Shared Collateral on a pari passu basis, ratably according to the Secured Liabilities owing to each Secured Party as specified in the following sentence. Proceeds from realization against such Shared Collateral shall be applied by the Agent
as follows: 
 (i) First to the Agent, with respect to fees and expenses accrued and outstanding
(including without limitation reasonable attorneys’ fees and expenses); and 
 (ii) Second
to the Secured Parties, ratably according to the Secured Liabilities owing to the Secured Parties. 
 The Lenders by unanimous consent may determine from time to time whether any, and which portions, of the Collateral is to be Shared Collateral beyond the Collateral described in Section 3.1.

 (b) If any Secured Party has payment made to it of proceeds arising from the foreclosure,
sale, set-off or other realization on any of the Shared Collateral pursuant to the remedies provided by the Collateral Documents in a greater proportion than that received by any other Secured Party (except for the Agent as specified in Subsection
(a) above), such Secured Party shall (and each Lender agrees to cause any of its Affiliates which are such a Secured Party to) take such action as is necessary such that all Secured Parties shall share in the benefits of such Shared Collateral
ratably in proportion to the Secured Liabilities owing to each Secured Party. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made. The foregoing sharing pertains solely to the
realization against the Shared Collateral and the proceeds therefrom, and is not a general sharing arrangement regarding the Secured Hedge Providers and the Agent and the Lenders for other purposes (including without limitation payments by the
Borrower and Subsidiaries from the Borrower’s and Subsidiaries’ general funds, including funds derived from the Shared Collateral or the other Collateral). The Agent and the Lenders shall have the right to receive, and the Borrower and
Subsidiaries shall have the right and obligation to pay, all amounts owing as part of the Indebtedness to be paid by the Borrower and Subsidiaries to the Agent and the Lenders as and when due. The Secured Hedge Providers shall have the right to
receive, and the Borrower and Subsidiaries shall have the right and obligation to pay, all amounts owing as part of the Secured Hedge Obligations to be paid by the Borrower and Subsidiaries to the Secured Hedge Providers as and when due. The Lenders
shall have the right to receive, and the Borrower shall have the right and obligation to pay, all amounts owing as part of the Banking Services Obligations to be paid by the Borrower to the Lenders as and when due. The foregoing sharing arrangement
pertains only to the proceeds arising from the foreclosure, sale, set-off or other realization pursuant to the remedies provided by the applicable Collateral Documents by the Agent, the Lenders and the Secured Hedge Providers on any of the
Collateral which secures all the Secured Liabilities. 
 (c) Should any payment or distribution
from any such realization upon any Shared Collateral or proceeds thereof (except payments permitted by Subsection (b) above) be received by any Secured Party before either the Indebtedness has, or the Secured Hedge

  
 -40-

 
Obligations or the Banking Services Obligations have, as the case may be, been paid and satisfied in full and terminated such that no further liabilities will be incurred thereunder, that Secured
Party shall (and each Lender shall cause any of its Affiliates which is a Secured Party to) deliver the same to the Agent in precisely the form received (except for the endorsement, without recourse, or assignment of that Secured Party where
necessary), for application on the Secured Liabilities ratably as provided in Subsection (a) above, and, until so delivered, the same shall be held in trust by that Secured Party as property of the Agent. 

(d) The agreement by the Agent and the Lenders to so share the Shared Collateral with the Secured Hedge
Providers is expressly conditioned upon and limited by (i) the right of the Agent and the Lenders, at any time and from time to time, to enter into such agreement or agreements with the Borrower and Subsidiaries as the Agent and the Lenders may
deem proper extending the time of payment or increasing or renewing or otherwise altering the terms of all or any of the Indebtedness without notice to the Secured Hedge Providers and without in any way impairing or affecting this Agreement,
(ii) the right of the Agent to release any portion or portions of the Collateral (including the Shared Collateral) from to time as the Agent and the Lenders may agree, and in connection therewith for the Agent to have the express power to
release any Secured Hedged Provider’s lien on the Shared Collateral under the Collateral Documents insofar as it secures the Secured Hedge Obligations, without notice to or such Secured Hedge Provider’s consent, so long as such Collateral
is simultaneously released insofar as it secures the Indebtedness; and (iii) the right of the Agent and the Lenders holding the Indebtedness to control all decisions and determinations in enforcing the Collateral Documents so long as any
portion of the Indebtedness remains outstanding, and decisions and determinations of the Required Lenders in enforcing the Collateral Documents and in guiding the Agent in such matters shall be binding upon the Secured Hedge Providers, including
without limitation when and whether to realize upon the Collateral (including the Shared Collateral), and when and whether to authorize the Agent at the pro rata expense of all the Secured Parties (to the extent not reimbursed by the Borrower) to
retain attorneys to seek judgment on the Collateral Documents. This Section 3.4 is expressly limited by the requirements and definitions in this Agreement for the creation of a Secured Hedge Obligation, and notwithstanding any provision
in any commodity, interest rate or currency rate protection agreement to the contrary, liabilities thereunder which do not meet the requirements and definitions in this Agreement for the creation of a Secured Hedge Obligations shall not be secured
by the Collateral or otherwise entitled to the benefits of this Section 3.4. The foregoing provisions of this Subsection 3.4(d) shall also apply with respect to the rights of the Agent and the Lenders with respect to any Lenders
which are owed Banking Services Obligations. 
 (e) This sharing of the Shared Collateral with
respect to the Secured Liabilities shall remain in full force and effect not withstanding any filing of a petition for relief by or against the Borrower under the Federal Bankruptcy Code or similar laws from time to time in effect and shall apply
with full force and effect with respect to all such Shared Collateral covered by the Collateral Documents acquired by the Borrower or any Grantor after the date of such petition and all Indebtedness, Secured Hedge Obligations and Banking Services
Obligations incurred after the date of such petition. Such sharing shall apply with full force and effect with respect to all Shared Collateral covered by the Collateral Documents from time to time, including without limitation pursuant to
supplements or amendments to the Collateral 

  
 -41-

 
Documents after the date hereof, subject to the foregoing preserved right of the Agent and the Lenders for partial releases. In the event of any liquidation, dissolution, receivership, insolvency
or bankruptcy proceeding, any payment or distribution of any kind or character, either in cash or other property, which shall be payable or deliverable upon or with respect to any or all of the Shared Collateral shall be paid or delivered directly
to the Agent for application as provided in Subsection 3.4(a). 
 (f) Neither the Agent
nor any of its directors, officers, agents or employees shall be liable to any Secured Hedge Provider for any action taken or omitted to be taken by it under or in connection with this Agreement, except for its or their own gross negligence or
willful misconduct. Without limiting the generality of the foregoing, the Agent (i) may treat a Secured Hedge Provider as the payee of its Secured Hedge Obligations until the Agent receives written notice of the assignment or transfer thereof,
signed by such Secured Hedge Provider in a form satisfactory to the Agent; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other experts selected by it and shall not be liable for any
action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Secured Hedge Provider and shall not be responsible to any Secured
Hedge Provider for any statements, warranties or representations made in or in connection with this Agreement or the Collateral Documents; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement or the Collateral Documents, or to inspect any property (including the books and records) of the Borrower and Subsidiaries; (v) shall not be responsible to any Secured Hedge Provider for the due
execution, legality, validity, enforce ability, genuineness, sufficiency or value of this Agreement or the Collateral Documents; and (vi) shall incur no liability under or in respect to this Agreement or the Collateral Documents by acting upon
any notice, consent, certificate or other instrument or writing (which may be by facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. The Agent shall not have a fiduciary relationship
in respect of any Secured Hedge Provider by reason of this Agreement. The Agent shall not have any implied duties to the Secured Hedge Providers, or any obligation to the Secured Hedge Providers to take any action under this Agreement or the
Collateral Documents except any actions specifically provided by such documents to be taken by it. The Agent shall have the same rights and privileges under this Agreement as any other Secured Hedge Provider and may exercise the same as though it
were not the Agent; and the term “Secured Hedge Provider” shall, unless otherwise expressly indicated, include the Agent in its individual capacity when applicable. The granting of benefits under this Agreement and the Collateral Documents
to the Secured Hedge Providers is expressly conditioned upon the benefits and protections provided to the Agent under Article 9 of this Agreement applying with each force and effect to the Secured Hedge Providers. 

(g) Notwithstanding any provision of this Section 3.4 to the contrary, if any Lender becomes a
Defaulting Lender, then the provisions of Section 2.15 shall apply for so long as such Lender is a Defaulting Lender. 
 Section 3.5 Future Subsidiaries to be Guarantors. The Borrower shall cause each new Subsidiary established or acquired after the Closing Date to execute and deliver a Guaranty 

  
 -42-

 
Agreement in form and substance satisfactory to the Agent securing the Secured Liabilities. For the avoidance of doubt, the foregoing does not limit or waive the provisions of
Section 6.3 (pursuant to which the Borrower shall not establish, acquire or otherwise own any new Subsidiary without the prior written consent of the Agent and the Required Lenders). 

Section 3.6 Release of Endeavor Collateral. (a) The Agent and the Lenders agree that they will release
the portions of the Collateral pertaining to Endeavor, as described in Subsection 3.1(a)(iv), (v), and (vi), and pertaining to Endeavor JV, as described in Subsection 3.1(a)(vii), respectively, all at the Borrower’s expense,
without need of further approval by the Lenders, upon a sale by Borrower of its ownership interest in, or the assets of, Endeavor, or Borrower’s ownership interest in Endeavor JV, respectively, if the net proceeds of such a sale received by the
Borrower are at least thirty million ($30,000,000.00) dollars and all such net proceeds are used either (x) to reduce the outstanding balance on the Indebtedness under this Agreement, if any, with a permanent reduction in the Amount if
requested by the Borrower and to the extent required by the Senior Unsecured Indenture, or (y) to acquire assets and properties in a transaction approved by the Required Lenders. 

(b) In the event that a sale of Borrower’s ownership interest in Endeavor (or of Endeavor’s
assets, with the proceeds ultimately being received by the Borrower) and the release of Collateral pertaining to Endeavor occurs under Subsection 3.6(a), this Agreement will be amended to remove the representations and covenants pertaining to
Endeavor, including without limitation those in Sections 3.1, 4.1, 4.16, 4.20, 5.17, 6.3 and 6.15. 
 (c) In the event that a sale of Borrower’s ownership interest in Endeavor JV and a release of Collateral pertaining to Endeavor JV occurs under Subsection 3.6(a), this Agreement will be
amended to remove the representations, covenants and Defaults pertaining to Endeavor JV, including without limitation those in the definition of “Debt” and in Sections 4.1, 4.7, 4.10, 4.16, 4.19, 4.20, 5.2, 5.11, 5.15, 6.1(g), 6.3(i),
6.15, 6.18, 6.19, 6.20, and 8.1(q). 
 Section 3.7 Release of Diamond. (a) The
Lenders acknowledge and agree that, promptly after the Closing Date, the Agent on behalf of the Secured Parties will release the Collateral granted by or pertaining to Diamond (Diamond’s security agreement and guaranty, and the pledge of
Diamond’s stock, but not the guaranty by Diamond). 
 (b) The Agent and the Lenders hereby
consent to a sale of the Borrower’s ownership interest in Diamond, or to a sale of some or all of the assets of Diamond, subject to the condition that, in each such instance, all of the net proceeds from each such sale are used in compliance
with the requirements of the Senior Unsecured Indenture. 
 (c) In the event that a sale of
Borrower’s ownership interest in Diamond occurs in compliance with this Section 3.7, the Agent and the Lenders agree that they will release the guaranty granted by Diamond if and when the guaranty by Diamond under the Senior
Unsecured Indenture is released (upon delivery of an officer’s certificate certifying thereto), and further this Agreement will be amended to remove the representations and covenants pertaining to Diamond, including without limitation those in
Sections 4.1, 4.20 5.20, 5.21 and 6.15.

limitation, costs of suit, reasonable attorneys’ fees and fees of expert witnesses) arising from or in connection with (i) the presence on or under all Collateral constituting real (immovable) property of any hazardous substances or solid
wastes (as defined elsewhere in this Agreement), or any releases or discharges of any hazardous substances or solid wastes on, under or from such property, or (ii) any activity carried on or undertaken on or off such property, whether prior to

 Section 5.15 Financial Covenants. The Borrower shall comply with the
following financial covenants (determined in accordance with Section 1.3), except as specifically stated otherwise: 
 (a) Minimum Current Ratio. The Borrower shall maintain, on a quarterly basis as of the last day of each fiscal quarter, a current ratio in an amount not less than 1.00 to 1.00. For purposes of this
Section, “current ratio” shall mean the ratio of (x) current assets plus the unused and available portion of the Commitment Limit (being the amount, if any, by which the Commitment Limit then in effect exceeds the sum of the
principal balance of unpaid and outstanding Advances and the total undisbursed amount of all letters of credit outstanding as of such date of determination) to (y) current liabilities (excluding therefrom the outstanding balance on the Loan).
This calculation will not include the effects, if any, of marking to market Hedging Obligations pursuant to Financial Accounting Standards Board Statement No. 133. 

  
 -59-

 
Notwithstanding the foregoing, the 2013 Convertible Debt shall not be considered a current liability upon satisfaction of the sale price condition (as described in Section 5.01(a)(i) of the
2013 Indenture), unless and until one or more notes constituting 2013 Convertible Debt are surrendered for conversion and then only to the extent of the cash payment due on the conversion of the notes surrendered. Notwithstanding the foregoing, the
2015 Convertible Debt shall not be considered a current liability upon satisfaction of the sale price condition (as described in Section 4.01(a)(i) the 2015 Indenture), unless and until one or more notes constituting 2015 Convertible Debt are
surrendered for conversion and then only to the extent of the cash payment due on the conversion of the notes surrendered. 
 (b) Minimum EBITDA to (Cash) Interest Expense. The Borrower shall maintain, on a quarterly basis as of the last day of each fiscal quarter, a ratio (on a rolling four fiscal quarter basis) of
EBITDA to Interest Expense during the four preceding fiscal quarters of not less than 2.50 to 1.00. 
 (c) Calculation. The Borrower acknowledges that any outstanding Qualified Redeemable Preferred Equity shall be counted and included as Debt for purposes of the financial covenants in this
Section 5.15. Without limiting the foregoing, the dividends payable under the Qualified Redeemable Preferred Equity shall be counted and included within Interest Expense for purposes of the financial covenant in Subsection 5.15(b)
and the financial covenant in Subsection 5.15(d). 
 (d) Total Senior Secured Debt to
EBITDA. The Borrower shall maintain, on a quarterly basis as of the last day of each quarter, a ratio (on a rolling twelve month basis) of Total Senior Secured Debt to EBITDA during the preceding twelve (12) months not to exceed 2.50 to
1.00. 
 (e) JV Calculation. The calculations of EBITDA for purposes of the financial
covenants in this Section 5.15 shall include cash distributions to Borrower from Endeavor JV. However, for the avoidance of doubt, the calculations of EBITDA for purposes of the financial covenants in this Section 5.15 shall
not include Borrower’s proportionate share of the net income of Endeavor JV (even if Borrower otherwise includes such proportionate share in its income statement). 

Section 5.16 Bank Accounts. (a) The Borrower shall maintain (and cause to be maintained) with the Agent
the Companies’ primary operating, money market/treasury management, collection and disbursement accounts, including without limitation as provided in Section 5.17. 

(b) The Borrower hereby grants to the Agent for the benefit of the Secured Parties a continuing security
interest in all of Borrower’s deposit accounts now existing or hereafter maintained with Agent as security for the Secured Liabilities, and all funds, investment property and proceeds pertaining thereto. 

(c) The Agent will be granted security interests by the Subsidiaries in all of their respective deposit
accounts (if any) (separate from the Borrower’s deposit accounts) 

  
 -60-

 
maintained with Agent as security for the Secured Liabilities, and all funds, investment property and proceeds pertaining thereto. 

Section 5.17 Revenues. (a) The Borrower and Endeavor each shall immediately deposit daily all payments
for oil or natural gas sales from the Borrower’s properties (whether or not such property is Collateral), or for resales thereof by Endeavor, to a revenue clearing deposit account with the Agent at all times. All such deposits shall be made no
later than the first Business Day after collection by such Company. Without limiting the foregoing, the Borrower shall use its best efforts to cause all Operators of any Company’s Collateral or purchasers from the Borrower or any Subsidiary
(including Endeavor) which make payments for oil or natural gas sales or purchases by electronic transfer payments to change such electronic payments to be made directly to Borrower’s or such Subsidiary’s accounts with the Agent. (The
foregoing covenant is separate from the Agent’s right after an Event of Default to send letters in lieu of transfer orders signed by the Borrower under Subsections 3.1(a) and 8.2(c) below.) 

(b) The Borrower, the Agent and the Lenders acknowledge that Collateral is comprised in part of the
Borrower’s undivided interests in mineral properties for which the Borrower is operator, and accordingly a portion of the payments made to the Borrower from the sale of hydrocarbons from such properties may be owed by the Borrower to the
non-operator working interest owners or to royalty or overriding royalty owners. In the event that revenues of another Person attributable to such other Person’s working interest or royalty or overriding royalty interest (“Other
Revenues”) are deposited into the revenue clearing account at the Agent, then the Agent and the Lenders agree that such Other Revenues will be released by the Agent to such Persons (even if an Event of Default has occurred and is continuing)
upon the receipt by the Agent of appropriate evidence that such funds are Other Revenues (i.e., are not the Borrower’s funds). The Agent and the Lenders shall not be liable, however, for any actions by Agent which are taken in compliance with
the terms of this Agreement and the Collateral Documents with respect to funds in the revenue clearing account that are Other Revenues and which are taken before Agent received such evidence that such funds are Other Revenues. 

(c) Upon the occurrence of any Event of Default, the Borrower shall upon Agent’s or the Required
Lenders’ request execute such division orders, transfer orders or letters in lieu thereof as are necessary to direct that all payments of mineral production due to the Borrower from its properties are paid directly to the Agent, including as
further provided in the Deed of Trust. 
 (d) Upon the release of the Collateral pertaining to
Endeavor under the conditions set forth in Section 3.6, this Section 5.17 shall no longer apply to Endeavor and its monies. 
 Section 5.18 Hedging Program. (a) At all times when the Percentage Outstanding exceeds seventy-five (75%) percent, the Borrower shall enter into and maintain in effect a hedging
program (the “Hedging Program”) consisting of Permitted Hedge Agreements that are mutually satisfactory to the Agent, the Required Lenders and the Borrower. 

  
 -61-

 (b) The Borrower’s commodity Hedge Agreements
(i) shall in no contract fix a price for a term of more than three (3) years, and (ii) in the aggregate shall not cover Obligated Volumes that exceed eighty five (85%) percent of the Borrower’s projected oil and gas PDP
production set forth in the most recent engineering report (third party or internal, as applicable) used in the Borrowing Base re-determination, all as further provided in the definition of Permitted Commodity Hedges. 

(c) If any Hedge Agreement of the Borrower or any Subsidiaries is used in the calculation of the Borrowing
Base, then such Hedge Agreement shall not be cancelled, liquidated or unwound (including by obtaining an opposite position) if such action, when aggregated with all other such actions and with all sales and dispositions under clause (v) of
Subsection 6.8(b) made during the time period between any two successive scheduled Borrowing Base redetermination dates, would cause the Material Value Change Amount to exceed in the aggregate five (5%) percent of the then effective
Borrowing Base, without the prior written consent of the Agent and the Required Lenders. 
 Section 5.19
Payables. The Companies shall pay all accounts payable for which applicable law grants the account holder a Lien against any property of such Company within 60 days from the date such payable is due and owing; provided, however, such Company
shall not be required to pay any such account if the amount or validity thereof shall currently be contested in good faith by appropriate proceedings diligently conducted and if such Company shall have set up reserves therefore adequate under
generally accepted accounting principles (provided that such reserves may be set up under generally accepted accounting principles) and so long as such contest proceedings conclusively operate to stay the sale of any property subject to such Lien to
satisfy such account. 
 Section 5.20 Diamond Loan. The Borrower shall cause any loan made by the
Borrower to Diamond to be unsecured. 
 Section 5.21 Diamond Limitation. The Borrower shall not, and
shall not permit Diamond or any Subsidiary, to own any drilling rig other than the three (3) drilling rigs owned by Diamond on July 15, 2007. (The Borrower must also comply with Subsection 6.3(g) below.) 

ARTICLE 6 

NEGATIVE COVENANTS 
 Unless the Agent’s and the Required Lenders’ (or if required by Section 10.4 hereof, all of the Lenders) prior written consent to the contrary is obtained, the Borrower will at all
times comply with the covenants contained in this Article 6 (including where applicable, without the necessity of expressly so stating in each instance, causing its Subsidiaries to comply with such covenant), from the date hereof and for so long as
any part of the Indebtedness is outstanding.

Subsection 8.1(n).] 

  

	 	(d)	 Taxes, assessments or other government charges which are not yet due or are being contested in good faith by appropriate action promptly initiated
and diligently conducted, if such reserve as shall be required by generally accepted accounting principles shall have been made therefor.

 -63-

	 	 
Agent’s and the Required Lenders’ prior written consent.

	 	(j)	 Debt under the Guaranty Agreement dated November 1, 2009 by the Borrower in favor of Endeavor JV, guaranteeing (only) the obligations of

	 	(k)	 The 2015 Convertible Debt. The 2015 Convertible Debt shall remain unsecured by any Liens, and shall not be subject to redemption or repurchase in
any part prior to maturity, except for redemptions or repurchases described in the 2015 Indenture. 

  

	 	(l)	 Senior Unsecured Notes existing on the Closing Date, on terms complying with the definition thereof.

JV, which is governed by Section 6.19) to, create, incur, assume or permit to exist any Lien on any of its property now owned or hereafter acquired, except for: 

 

	 	(a)	 Liens for taxes, assessments, or other governmental charges not yet due or which are being contested in good faith by appropriate action promptly
initiated and diligently conducted, if such reserve as shall be required by generally accepted accounting principles shall have been made therefor, and so long as the payment of same is not a condition to be met in order to maintain in force such

interest in such property or (if applicable) the Agent’s first Lien therein. 

  

	 	(b)	 Liens of landlords, vendors, carriers, warehousemen, mechanics, laborers and materialmen arising by law in the ordinary course of business for sums

	 	(e)	 Minor imperfections of title or non-monetary Liens that do not materially impair the development, operation or value of property in its intended use
or the title thereto and which are of a nature commonly existing with respect to properties of a similar character as the Collateral. 

  

	 	(f)	 Royalties, overriding royalties, net profits interests, production payments, reversionary interests, calls on production, preferential purchase
rights and other burdens on or deductions from the proceeds of production, that do not secure Debt for borrowed money and that are taken into account in computing the net revenue interests and working interests of the Borrower warranted in the
Collateral Documents. 

  
 -65-

	 	(g)	 Operating agreements, unitization and pooling agreements and orders, farmout agreements, gas balancing agreements and other agreements, in each case
that are customary in the oil, gas and mineral production business in the general area of such property and that are entered into in the ordinary course of business in good faith. [For the avoidance of doubt, it is acknowledged that this covenant is
separate and independent of the Event of Default under Subsection 8.1(n).]

	 	(j)	 The PVOG Production Payment (non-recourse to the Borrower except as provided in the definition thereof). 

The inclusion of this Section 6.2 shall not constitute in any way an acknowledgment by the Agent and the Lenders of the validity,
legality, enforceability or binding effect on the Agent and the Lenders of such Liens, the sole purpose of this provision being to provide that the existence of any such permitted Liens shall not in and of itself constitute an Event of Default under
this Agreement. 
 Section 6.3 Investments, Loans and Advances. The Borrower will not (directly or
indirectly through any Subsidiary), and will not allow or suffer any Subsidiary to, make or permit to remain outstanding any loans or advances or extensions of credit to, or purchases or other acquisitions of capital stock or ownership (direct or
beneficial) interests or obligations of, or other investments in, any Person (including without limitation any Subsidiary), except for:

more of such other lenders.

(3) drilling rigs in service (including the initial placement of the third drilling rig in service). For the avoidance of doubt, the Borrower acknowledges that the foregoing restriction (and Section 5.21), without limitation,
requires the Agent’s and the Required Lenders’ consent to any investment, loan or advance to 

  
 -67-

	 	 
permit Diamond to acquire an additional drilling rig.

shall not establish, acquire or otherwise own any new Subsidiary after the Closing Date, without in each case the prior written consent of the Agent and the Required Lenders. 

Section 6.4 Nature of Business. The Borrower will not permit any material change to be made in the character
of its business or the business of any Subsidiary as carried on at the Closing Date (or as to a Subsidiary established or acquired after the Closing Date (in compliance with Section 6.3) as carried on at such time of establishment or
acquisition. 
 Section 6.5 Mergers and Consolidations. The Borrower will not, and will not allow or
suffer any Subsidiary to, acquire, merge with or consolidate with any Person or acquire by purchase, lease or otherwise all or substantially all of the assets of any Person (whether or not such acquisition, merger or consolidation requires any
capital expenditures on the part of the Borrower). 
 Section 6.6 ERISA Compliance. The Borrower
will not at any time permit any Plan maintained by it to engage in any “prohibited transaction” as such term is defined in Section 4975 of the Code; incur any “accumulated funding deficiency” as such term is defined in
Section 302 of ERISA; or terminate any such Plan in a manner which could result in the imposition of a Lien on the property of the Borrower pursuant to Section 4068 of ERISA. 

Section 6.7 Changes. Each Company will not without 30 days prior notice to the Agent change the location of
any of its Collateral, or change the location of its state of organization or chief executive office or change its name.

 Section 6.8 Sales. (a) The Borrower will not, and will not
allow or suffer any Subsidiary to, sell, assign, transfer by bond for deed, lease or otherwise dispose of (whether in one transaction or in a series of transactions) all or substantially all of its property (whether now owned or hereafter acquired)
to any Person. 
 (b) The Borrower will not, and will not allow or suffer any Subsidiary to, sell, assign,
transfer by bond for deed, lease or otherwise dispose (including by any sale-leaseback transaction) of any of its Collateral or any material portion of its other property, business, or assets, including without limitation any producing mineral
properties or equity interests in a Subsidiary, except for (i) sales of production (in compliance with the terms of the Collateral Documents and this Agreement), (ii) collection of its accounts, (iii) sales of items of
equipment which are obsolete or otherwise no longer useful for such Person’s operations, (iv) sales of items of equipment to the extent the proceeds of such sale are promptly reinvested in the acquisition of replacement equipment, and
(v) sales or other dispositions of mineral properties Collateral which, when aggregated with all other such sales and with all hedge adjustments under Subsection 5.18(c) made during the time period between any two successive scheduled
Borrowing Base redetermination dates, do not cause the Material Value Change Amount to exceed in the aggregate five (5%) percent of the then effective Borrowing Base, in each case in clauses (i) through (v) above in the ordinary
course of business. For purposes of the preceding sentence, “material” means asset sales which exceed in the aggregate $100,000.00 during any one fiscal year. The Agent’s and Required Lenders’ consent for sales or other
dispositions of mineral properties which will exceed the permitted 5% amount shall not be unreasonably withheld, provided that the Borrower pays in full on or before such sale or disposition the amount, if any, by which the outstanding principal
balance of the Advances plus the undisbursed amount of all outstanding standby letters of credit issued pursuant to this Agreement exceeds a redetermined Borrowing Base after giving effect to the proposed asset sale, as such decreased Borrowing Base
may be determined by the Required Lenders in their complete and sole discretion. The Agent is authorized by the Lenders to execute and deliver releases of the Collateral covering property sold or otherwise disposed of under clauses (iii),
(iv) and (v) above. 
 Section 6.9 Agreements. Each Company will not enter into or be a
party to any contract or agreement for the purchase of materials, supplies or other property or services if such contract or agreement shall require that such Company make payment for such materials, supplies or other property irrespective of
whether delivery thereof is made or whether such services are rendered. Except in the ordinary course of business, each Company will not enter into any arrangement with any gas pipeline company or any other purchaser of hydrocarbons regarding the
Collateral whereby the Company agrees that said gas pipeline company or purchaser may set off any claim against the Company by withholding payment for any hydrocarbons actually delivered. 

Section 6.10 Distributions or Redemption. (a) The Borrower will not (i) pay or declare any dividend
on any shares of any class of its stock (other than stock dividends), (ii) make any other distribution or other shareholder expenditure on account of any shares of any class of its stock, nor set aside any funds for such purpose, nor
(iii) otherwise make or agree to pay for or make (except as set forth in (b) below), directly or indirectly, any other distribution with respect to any shares of any class of its stock, or any payment (whether in cash, securities or other

  
 -69-

 
property), including any sinking fund or similar deposit, on account of the purchase, redemption, retirement, acquisition, cancellation or termination of any such shares or any option, warrants
or other right to acquire any such shares, except that if at the time thereof and immediately after giving effect thereto no Default or Event of Default shall have occurred and be continuing (or be created), and no Loan Excess shall then
exist, the Borrower may declare, and agree to declare and pay, dividends (interest expense) in cash to the holders of Qualified Redeemable Preferred Equity, and the Borrower may make and pay such cash dividends so declared within thirty
(30) days of such declaration. For the avoidance of doubt, shares of Qualified Redeemable Preferred Equity are Borrower’s stock for purposes of clauses (i), (ii) and (iii) above, and the Borrower shall not elect (or agree to
elect) any option to redeem any Qualified Redeemable Preferred Equity without the prior written consent of the Required Lenders. Notwithstanding the foregoing, the Borrower may make or agree to pay for or make a payment (whether in cash, securities
or other property) on account of the purchase, redemption, retirement, acquisition, cancellation or termination of the 2013 Convertible Debt or the 2015 Convertible Debt (including any interest payment with respect to the 2013 Convertible Debt or
the 2015 Convertible Debt on such account), to the extent that the foregoing is an option or other right to acquire common stock of the Borrower, to the extent (and only to the extent) not prohibited by Section 6.17. 

(b) The Qualified Redeemable Preferred Equity issued by Borrower may include (as provided in clause
(ii) of the definition thereof) a provision providing for a mandatory redemption of such stock following a change of ownership or control or management (as contemplated by Sections 6.13 or 6.12, respectively). Moreover, the Borrower may
make a mandatory redemption payment on the Qualified Redeemable Preferred Equity solely by reason of a change of ownership or control or management (as contemplated by Sections 6.13 or 6.12, respectively), and such mandatory redemption
payment in itself is not an Event of Default (although nothing set forth in this Agreement shall subordinate the Secured Parties’ rights to priority of payment). However, the Borrower acknowledges that nothing set forth in this
Section 6.10 (or in the definition of Qualified Redeemable Preferred Equity or Subsection 8.1(o) below) modifies or restricts the application of Section 6.12 and Section 6.13, and if a change in management
or a change in ownership or control, respectively, occurs within the meaning of those Sections then an Event of Default occurs under Subsection 8.1(c) unless the Agent’s and the Required Lenders’ prior written consent to the
contrary is obtained (even though any mandatory redemption of Qualified Redeemable Preferred Equity which also may arise due to such change in management, ownership or control is not itself a breach of this Section 6.10 or an Event of
Default). 
 Section 6.11 Subordinated Preferred Equity Financings. (a) The Borrower shall not
make any cash or other payment or transfer of property on account of any Qualified Redeemable Preferred Equity except as expressly permitted under Section 6.10 hereof. 

(b) The Borrower shall not enter into or agree to any amendment, modification or waiver of any term or
condition of, or any of its rights under, the documents pertaining to any issued Qualified Redeemable Preferred Equity, which amendment, modification or waiver could, in the reasonable opinion of the Agent, materially and adversely affect the
interests of the Lenders. 

  
 -70-

 Section 6.12 Management. The Borrower will not permit or suffer
a change in the key management of the Borrower and its Affiliates to occur. For purposes of this Section, key management shall mean the continued active full time employment of Ken Kenworthy, Jr. (as CEO); provided, however, that the
cessation of active employment of such officer due to death or disability shall not be a Default hereunder so long as the Borrower hires or promotes a replacement officer with experience and qualifications reasonably acceptable to the Agent and the
Required Lenders within four (4) months of the former officer’s cessation of activity. 

Section 6.13 Change of Ownership or Control. (a) No Person or group (as defined in Section 13(d)(3)
of the Securities Exchange Act of 1934), other than existing management of Borrower as of the Closing Date, shall become the beneficial owner of more than 50% of the total voting power of the capital stock of the Borrower then outstanding.

 (b) A majority of the members of the Board of Directors of the Borrower shall not cease to be
Continuing Directors. For purposes of this Section, the term “Continuing Directors” of a Person means any member of such Person’s Board of Directors who: (x) was a member of such Person’s Board of Directors on the Closing
Date; or (y) was nominated for election or elected with the approval of a majority of the Continuing Directors who were then members of such Person’s Board of Directors (but excluding any such individual whose initial assumption of office
occurs as a result of either an actual or threatened election contest or other actual or threatened solicitation of proxies or consents by or on behalf of a Person other than the Continuing Directors). 

Section 6.14 Transactions with Affiliates. The Borrower will not sell, transfer, lease or otherwise dispose
of (including pursuant to any merger) any property or assets to, or purchase, lease or otherwise acquire (including pursuant to a merger) any property or assets from, or otherwise engage in any other transactions with, any Affiliates, except in the
ordinary course of business at prices and on terms and conditions not less favorable to the Borrower as could be obtained on an arms-length basis from unrelated third persons in a comparable transaction. 

Section 6.15 Subsidiaries. The Borrower will not allow or suffer any changes to be made in the ownership
structure of each Subsidiary, and shall not own and control directly or indirectly less than one hundred (100%) percent of the ownership and voting rights in each Subsidiary other than Endeavor JV. The Borrower will not create, incur, assume or
permit to exist any Lien on its equity interest in any Subsidiary, other than in favor of the Agent. Notwithstanding the foregoing, in the event of a sale of the Borrower’s ownership interest in Endeavor which is in compliance with
Section 3.6, this Section 6.15 shall be automatically considered amended to permit such change with respect to the Borrower’s ownership of Endeavor without need of further consent of the Lenders. 

Section 6.16 Restrictive Agreements. The Borrower will not directly or indirectly enter into, incur or permit
to exist, or permit any Subsidiary so to do, any agreement or other arrangement that (i) prohibits, restricts or imposes any condition upon the ability of a Subsidiary to create, incur or permit to exist any Lien upon any of its property or
assets or (ii) prohibits, restricts or imposes any condition upon the ability of any Subsidiary to pay dividends or other distributions with respect to any shares of its equity securities or other ownership interest or to

  
 -71-

 
repay to the Borrower any loans or advances, provided that (x) the foregoing shall not apply to restrictions and conditions imposed by corporate law or by this Agreement, (y) clause
(i) of this Section shall not apply to customary provisions in leases restricting the transfer thereof, and (z) this Section 6.16 shall not apply to Endeavor JV.

other payment (whether in securities or other property), including any sinking fund or similar deposit, on account of the conversion, redemption, retirement, purchase, acquisition, cancellation or termination of any of the (i) 2013 Convertible
Debt prior to February 1, 2013 or (ii) 2015 Convertible Debt prior to February 1, 2014, whether optional or mandatory by the Borrower, except that (1) the Borrower may issue common stock (and cash in lieu of any fractional
share thereof) on conversion of any 2013 Convertible Debt and/or 2015 Convertible Debt, (2) if at the time thereof and immediately after giving effect thereto no Default or Event of Default shall have occurred and be continuing (or be created),
and no Loan Excess shall then exist, the Borrower may make any cash payment and may issue any other securities required upon any conversion, redemption, retirement, purchase, acquisition, cancellation or termination of the 2013 Convertible Debt

after giving effect thereto, a Default or Event of Default shall have occurred and be continuing (or be created) or a Loan Excess shall then exist, except that the Borrower may issue common stock (and cash in lieu of any fractional share
thereof) on conversion of any 2013 Convertible Debt and/or 2015 Convertible Debt in connection with any deemed interest payment thereof as described in the 2013 Indenture and the 2015 Indenture. 

(c) The Borrower shall issue and maintain the 2013 Convertible Debt and the 2015 Convertible Debt only on
terms that are consistent in all material respects with the respective descriptions of the 2013 Convertible Debt and the 2015 Convertible Debt set forth in the 2013 Indenture and the 2015 Indenture previously provided to the Lenders, subject to the
limitations set forth in Subsection 6.1(i) and Subsection 6.1(k), respectively. The Borrower shall not enter into or agree to any amendment, modification or waiver of any term or condition of, or any of its rights under, the documents
pertaining to any issued 2013 Convertible Debt or the 2015 Convertible Debt, if, within 10 Business Days following written notice of any such amendment, modification or waiver, the Agent provides written notice to the Borrower that such

  
 -72-

 
amendment, modification or waiver in the reasonable opinion of the Agent, acting in good faith, materially and adversely affects the interests of the Lenders.

6.13 or 6.12, respectively). For the avoidance of doubt, nothing in this Subsection modifies or restricts the application of Section 6.10, Section 6.11, Section 6.12 or Section 6.13, nor does this Subsection
modify or limit Subsection 8.1(c) above. 

  

	 	(p)	 Fundamental Change. A “Fundamental Change” as defined in either the 2013 Indenture or the 2015 Indenture occurs.

  

	 	(q)	 Endeavor JV. A Default occurs in respect of the Borrower under the Endeavor JV Agreement; or an advance by the other member occurs in respect
of any Capital Contribution owing by Borrower under Section 4.3 of the Endeavor JV Agreement; or the other member of the Endeavor JV Agreement exercises any remedies with respect to its security interest in the Borrower’s membership
interest in Endeavor JV. In the event of a sale of the Borrower’s interests in Endeavor JV that complies with Section 3.6, this Subsection 8.1(q) shall be automatically considered amended and shall no longer apply or be in
effect.

 Section 8.2 Remedies. (a) Upon the happening of any Event
of Default specified in the preceding Section (other than Subsections (g) or (h) thereof), (i) all obligations, if any, of the Lenders to make Advances to the Borrower or issue letters of credit at the request of the Borrower shall
immediately cease and terminate, and (ii) the Agent shall at the direction, or may with the consent, of the Required Lenders by written notice to the Borrower declare the entire principal amount of all Indebtedness then outstanding including
interest accrued thereon to be immediately due and payable without presentment, demand, protest, notice of protest or dishonor or other notice of default of any kind, all of which are hereby expressly waived by the Borrower. 

(b) Upon the happening of any Event of Default specified in Subsections (g) or (h) of the
preceding Section, (i) all obligations, if any, of the Lenders to make Advances to the Borrower or issue letters of credit at the request of the Borrower shall immediately cease and terminate, and (ii) the entire principal amount of all
obligations then outstanding including interest accrued thereon shall, without notice or action by the Agent and the Lenders, be immediately due and payable without presentment, demand, protest, notice of protest or dishonor or other notice of
default of any kind, all of which are hereby expressly waived by the Borrower. 
 (c) In addition
to the foregoing, the Agent may exercise any of the rights and remedies established in the Collateral Documents or avail itself of any other rights and remedies provided by applicable law, including without limitation completing and sending the
letters described in Subsection 3.1(a). In the event the Agent sends such letters, the Agent agrees that it shall request such purchasers of production to remit any proceeds net of lease operating expenses and production taxes. However, the
Agent may accept any gross payments made despite such requests without liability thereunder. 

(d) In furtherance of the foregoing, to the extent that any standby letters of credit are outstanding upon
the occurrence of any Event of Default, the Agent may by written notice to the Borrower require the Borrower to pay to the Agent immediately on such demand the full undisbursed amount of such letters of credit to be held by the Agent as collateral
for the payment of such letters of credit. Such amount shall bear interest from demand until paid at the Default Rate notwithstanding any interest rate provision to the contrary in any letter of credit application or agreement between the Borrower
and the Issuing Bank, even if executed after this Agreement. 
 Section 8.3 Set-Off. Upon the
occurrence of any Event of Default, the Agent and the Lenders shall have the right to set-off any funds of the Borrower or any Company in the possession of the Agent or such Lender (including without limitation funds in the accounts provided for in
Article 5) against any amounts then due by the Borrower to the Agent or such Lender pursuant to the Agreement (but the Borrower acknowledges that the Agent may apply funds in such accounts against any interest, fee or mandatory principal
prepayment amounts then due and payable by the Borrower even without the occurrence of an Event of Default). The Borrower agrees that any holder of a participation in any Note may exercise any and all rights of counter-claim, set-off, banker’s
lien and other liens with respect to any and all monies owing by Borrower to such holder as fully as if such holder of a participation were a holder of a note in the amount of such participation. 

  
 -84-

 Section 8.4 Marshaling. The Companies shall not in any time
hereafter assert any right under any law pertaining to marshaling (whether of assets or liens) and the Borrower expressly agrees that the Agent may execute or foreclose upon the Collateral Documents in such order and manner as the Agent, in its sole
discretion, deems appropriate. 
 ARTICLE 9 
 THE AGENT 
 Section 9.1 Appointment and Authorization.
(a) Each Lender irrevocably appoints and authorizes the Agent to receive all payments of principal, interest, fees and other amounts payable by the Borrower under this Agreement and to remit same that is payable to the Lenders promptly to the
Lenders, to disburse the Advances from the Lenders, and to take such action and to exercise such powers under this Agreement, the Notes, and the Collateral Documents as are delegated to the Agent by the Lenders from time to time. The Agent shall
promptly distribute to the Lenders upon receipt all payments and prepayments of principal, interest, fees (except for those fees which by their express terms are payable on another basis) and other amounts paid by the Borrower under this Agreement
that are payable to the Lenders, in proportion to the Lenders’ Commitments. Similarly, the Lenders shall be obligated to fund Advances in proportion to their Commitments. If the Agent receives a payment in immediately available funds by 11:00
a.m. (Central Time), the Agent will make available to each Lender on the same date, by wire transfer of immediately available funds, such Lender’s ratable share of such payment, and if such payment is received after 11:00 a.m. (Central Time) or
in other than immediately available funds, the Agent will make available to each Lender its ratable share of such payment by wire transfer of immediately available funds on the next succeeding Business Day (or in the case of uncollected funds, as
soon as practicable after collected). If the Agent shall not have made a required distribution to the Lenders as required by the preceding sentence after receiving a payment for the account of such Lenders, the Agent shall pay to each such Lender,
on demand, its ratable share of such payment with interest thereon at the Federal Funds Rate (as defined in the next sentence) for each day from the date such amount was required to be disbursed by the Agent until the date repaid to such Lender. The
Federal Funds Rate shall mean, for any day, an interest rate per annum (expressed as a decimal, rounded upwards, if necessary, to the next higher 1/100 of 1%) equal to the weighted average of the rates on overnight federal funds transactions with
members of the Federal Reserve System arranged by federal funds brokers on such day, as published for such day (or, if such day is not a Business Day, for the immediately preceding Business Day) by the Federal Reserve Bank of New York, or, if such
rate is not so published for any day which is a Business Day, the average of the quotations at approximately 10:00 a.m. (Central Time) on such day on such transactions received by the Agent from three federal funds brokers of recognized standing
selected by the Agent. Notwithstanding any provision of this Subsection 9.1(a) to the contrary, if any Lender becomes a Defaulting Lender, then the provisions of Section 2.15 shall apply for so long as such Lender is a Defaulting
Lender 
 (b) The Agent or the Issuing Bank may resign at any time by written notice to the
Lenders and the Borrower. The Agent or the Issuing Bank may be removed at any time with or without cause by the Required Lenders. The successor Agent or successor Issuing Bank shall be selected by the Required Lenders from among the remaining
Lenders. If no successor Agent 

  
 -85-

 
or successor Issuing Bank has been so appointed by the Required Lenders (and approved by the Borrower as provided below) and has accepted such appointment within thirty (30) days after such
notice of resignation or removal, then the retiring Agent or retiring Issuing Bank may, on behalf of the Lenders and the Borrower, appoint a successor Agent or successor Issuing Bank from among the remaining Lenders. Any successor Agent or successor
Issuing Bank must be approved by the Borrower, which approval will not be unreasonably withheld, delayed or conditioned. Upon the acceptance of any appointment as Agent or Issuing Bank by a successor Agent or successor Issuing Bank, such successor
Agent or successor Issuing Bank shall thereupon succeed to and become vested with all the rights, powers, privileges, and duties of the retiring Agent or retiring Issuing Bank, and the retiring Agent or retiring Issuing Bank shall be discharged from
its duties and obligations under this Agreement and the Collateral Documents, except that the retiring Issuing Bank shall remain the Issuing Bank with respect to any letters of credit outstanding hereunder on the effective date of its resignation or
removal and the provisions affecting the Issuing Bank with respect to such letters of credit shall inure to the benefit of the retiring Issuing Bank until the termination of all such letters of credit. After any retiring Agent’s or retiring
Issuing Bank’s resignation or removal hereunder as Agent or Issuing Bank, the provisions of this Article 9 shall inure to its benefit as to any actions taken or omitted to be taken while it was acting as Agent or Issuing Bank. 

(c) Each Lender irrevocably appoints and authorizes the Agent to hold this Agreement and the Collateral
Documents (but not the Notes, which will be held by the respective Lenders), and to take such action and exercise such powers under this Agreement, the Notes and the Collateral Documents as are delegated to the Agent by the Lenders from time to
time. Any requests by the Borrower for consent by the Lenders or waiver or amendment of provisions of this Agreement shall be delivered by the Borrower to the Agent, but favorable action on such requests shall require the approval of the Required
Lenders or all of the Lenders, as the case may be. 
 (d) Each Lender authorizes the Agent to
execute and deliver to the Borrower on the Lenders’ behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of Collateral which shall be permitted by the terms hereof or of any other Loan
Document or which shall otherwise have been approved by the Required Lenders (or, if required by the terms of Section 10.4, all of the Lenders) in writing. 

(e) Each Lender authorizes the Agent to supervise the syndication of the Loan to a group of financial
institutions identified by the Agent in consultation with the Borrower in accordance with the provisions of Section 9.6 hereof. 
 (f) Each Lender hereby appoints Capital One, National Association as its contractual representative hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Agent
to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this
Article 9. Notwithstanding the use of the defined term “Agent,” it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document
and that the Agent is merely acting as the contractual 

  
 -86-

 
representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders’ contractual representative,
the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a “representative” of the Lenders within the meaning of Section 9-105 of the Uniform Commercial Code and (iii) is acting as an
independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Subject to the provisions of Section 9.2, each of the Lenders hereby agrees to assert no
claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives. 
 Section 9.2 Agent’s Reliance. Neither the Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it under or in
connection with the Loan Documents, except for its or their own gross negligence or willful misconduct. Without limiting the generality of the foregoing, the Agent: (i) may treat the payee of any of the Notes as the holder thereof until the
Agent receives written notice of the assignment or transfer thereof, signed by such payee and in form satisfactory to the Agent; (ii) may consult with legal counsel (including counsel for the Borrower), independent public accountants and other
experts selected by it and shall not be liable for any action taken or omitted to be taken by it in good faith in accordance with the advice of such counsel, accountants or experts; (iii) makes no warranty or representation to any Lender and
shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with the Loan Documents; (iv) shall not have any duty to ascertain or to inquire as to the performance or observance of any of the
terms, covenants or conditions of this Agreement, the Notes or the Collateral Documents (except receipt of items expressly required to be delivered to the Agent hereunder), or to inspect any property (including the books and records) of the
Borrower; (v) shall not be responsible to any Lender for the due execution, legality, validity, enforce ability, genuineness, sufficiency or value of any of the Loan Documents; and (vi) shall incur no liability under or in respect to the
Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (which may be by facsimile, telegram, cable or telex) believed by it to be genuine and signed or sent by the proper party or parties. The Agent shall not
have a fiduciary relationship in respect of any Lender by reason of this Agreement. The Agent shall not have any implied duties to the Lenders, or any obligation to the Lenders to take any action under the Loan Documents except any actions
specifically provided by such documents to be taken by it. For the avoidance of doubt, this Section 9.2 also applies to any Lender in its capacity as a provider of Banking Services. 

Section 9.3 Acts by Agent after Default, etc. In the event that the Agent shall have been notified in writing
by any of the Borrower or the Lenders of any Event of Default (or in the event that the officer of the Agent responsible for the Borrower’ account obtains actual knowledge of an Event of Default), the Agent (i) shall immediately notify the
Lenders; (ii) shall take such action and assert such rights under this Agreement as it is expressly required to do pursuant to the terms of this Agreement with the consent of or direction by the Required Lenders; (iii) may take such other
actions and assert such other rights as it deems advisable, in its discretion, for the protection of the interests of the Lenders pursuant to applicable laws with the consent of the Required Lenders; and (iv) shall inform all the Lenders of the
taking of action or assertion of rights pursuant to this Section. Each Lender agrees with the Agent and the other 

  
 -87-

 
Lenders that the decisions and determinations of the Required Lenders in enforcing the Loan Documents and guiding the Agent in those matters shall be binding upon all the Lenders, including
without limitation authorizing the Agent at the pro rata expense of all the Lenders (to the extent not reimbursed by the Borrower) to retain attorneys to seek judgment on the Loan Documents. Each Lender agrees with the other Lenders that it will
not, without the consent of all the other Lenders, separately seek to institute any legal action with respect to the Loan. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any Collateral
Document in accordance with written instructions signed by the Required Lenders (or, where required, all the Lenders), and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders and on all of
the holders of Notes, provided, however, that the Agent shall not be required to take any action which exposes the Agent to personal liability or which is contrary to this Agreement or applicable law. 

Section 9.4 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance
upon the Agent or any other Lender and based on the financial statements referred to herein and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender
also acknowledges that it will, independently and without reliance upon the Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not
taking action under the Loan Documents. No representation or warranty, express or implied, is made by the Agent as to the accuracy or completeness of information provided by the Borrower to the Lenders, and the Agent assumes no responsibility for
its accuracy or completeness. 
 Section 9.5 Agent as Lender. The Agent shall have the same rights
and powers under the Loan Documents as any other Lender and may exercise the same as though it were not the Agent; and the term “Lender” or “Lenders” shall, unless otherwise expressly indicated, include Agent in its individual
capacity. The Agent may accept deposits from, lend money to, act as trustee under indentures of, and generally engage in any kind of business with Borrower and its Subsidiaries as if the Agent were not the Agent and without any duty to account
therefor to the Lenders. The Lenders acknowledge that Section 3.4 shall govern the relationship among the Secured Parties with respect to the Secured Liabilities (including without limitation Banking Services). 

Section 9.6 Assignments and Participations. (a) No Lender may assign to any other Person any portion of
its interests, rights and obligations under this Agreement (including, without limitation, any portion of its Commitment or the Loan at the time owing to it and Note held by it) unless each of the following conditions is or has been satisfied:
(i) the Agent has given its prior written consent (which consent will not be unreasonably withheld), (ii) the Borrower has given its prior written consent (which consent will not be unreasonably withheld, and shall be presumed to have been
granted if Borrower does not object within five (5) Business Days after notice thereof, and further shall not be required upon the occurrence and during the continuance of an Event of Default), (iii) each such assignment is of a constant,
and not a varying, percentage of all the assigning Lender’s rights and obligations under this Agreement, (iv) the assignment is for a Commitment of $5,000,000.00 or more, (v) the parties to such assignment have executed and delivered
to the Agent an Assignment and Acceptance, 

  
 -88-

 
substantially in the form of Exhibit B hereto (the “Assignment and Acceptance”), together with any Note subject to such assignment, one or more signature pages to this
Agreement containing the signature of the assignee, and (following the Effective Date, as defined in the applicable Assignment and Acceptance) payment by the assignee to the Agent for its own account of an assignment administration fee in the amount
of $3,500.00 (unless waived by the Agent in its sole and absolute discretion), (vi) either the assignor or assignee shall have paid the Agent’s reasonable costs and expenses (including without limitation attorneys’ fees and expenses)
in connection with the assignment, (vii) the Agent shall have delivered to the Borrower a fully executed copy of such Assignment and Acceptance, and (viii) the assignee is (A) a state or national commercial bank located in the United
States or (B) a bank organized under a jurisdiction other than the United States, provided that such foreign bank has provided the Agent and the Borrower with accurate and complete signed original forms prescribed by the Internal Revenue
Service certifying as to such Lender’s status for purposes of determining exemption from United States withholding taxes with respect to all payments to be made to such Lender hereunder, and provided further that such foreign bank shall not
transfer its interests, rights and obligations under this Agreement to any Affiliate of such foreign bank unless such Affiliate provides the Agent and the Borrower with the aforesaid tax forms. Upon satisfaction of each of the foregoing conditions
and upon acceptance and notation by the Agent, from and after the Effective Date specified in each Assignment and Acceptance, which Effective Date shall be at least five (5) Business Days after the execution thereof, (x) the assignee
thereunder shall be a party hereto and, to the extent provided in such Assignment and Acceptance, have the rights and obligations of a Lender, and (y) the assigning Lender shall, to the extent provided in such assignment, be released from its
obligations under this Agreement. Notwithstanding the foregoing, the restrictions contained above in this Subsection 9.6(a) shall not apply to assignments to any Federal Reserve Bank, and the conditions set forth in clauses (i) and
(ii) above shall not apply to assignments by any Lender to any Person which controls, is controlled by, or is under common control with, or is otherwise substantially affiliated with that Lender. 

(b) Upon its receipt of an Assignment and Acceptance executed by the parties to such assignment together
with any Note subject to such assignment and the written consent of the Agent and the Borrower to such assignment, the Agent shall give prompt notice thereof to the Borrower and the Lenders. Within five (5) Business Days after receipt of such
notice, the Borrower at its own expense, shall execute and deliver to the Agent, in exchange for the surrendered Note, a new Note to the order of such assignee(s) in an amount equal to the amount assumed by such assignee(s) pursuant to such
Assignment and Acceptance and, if the assigning Lender has retained some portion of its obligations hereunder, a new Note to the order of the assigning Lender in an amount equal to the amount retained by it hereunder. Such new Note or Notes shall be
in an aggregate principal amount equal to the aggregate principal amount of the surrendered Note, shall be dated the effective date of such Assignment and Acceptance and shall otherwise be in the form of the assigned Note. The surrendered Note shall
be canceled and returned to the Borrower. The Agent shall have the right to substitute a revised Schedule 1 hereto to reflect the respective Commitments following each such assignment. 

(c) Each Lender, without the consent of the Agent or the other Lenders (or the Borrower), may sell
participations to one or more lenders or other financial institutions (and such bank or lenders or financial institution or financial institutions shall be bound by the terms of this 

  
 -89-

 
Agreement, including without limitation this Section 9.6) in all or a portion of the Loan (including its Commitment) under this Agreement; provided, that the selling Lender shall
retain the sole right and responsibility to enforce the obligations of the Borrower relating to the Loan and that the only rights granted to the participant pursuant to such participation arrangements with respect to waivers, amendments or
modifications of this Agreement shall be the right to approve waivers, amendments, or modifications which require the consent of all of the Lenders as provided in Section 10.4 hereof. Notwithstanding the foregoing, the Borrower’s
consent shall not be required for any participation granted to any Federal Reserve Bank. 
 Section 9.7

capacity as Issuing Bank), its respective Affiliates, and the respective shareholders, directors, officers, employees, agents and counsel of the foregoing (each an “Agent Indemnitee”) and hold each Agent Indemnitee harmless from and
against any and all claims (whether groundless or otherwise), liabilities, losses, damages, costs and expenses of any kind (including, without limitation, (i) the reasonable fees and disbursements of counsel and (ii) any expenses for which
the Agent or the Issuing Bank has not been reimbursed by the Borrower as required by this Agreement) which may be incurred by such Agent Indemnitee arising out of or related to this Agreement or the transactions contemplated hereby, or the
Agent’s actions taken hereunder (including the Agent Indemnitee’s own negligence), or the Issuing Bank’s actions taken hereunder (including the Agent Indemnitee’s own negligence); provided, that no Agent Indemnitee shall have the
right to be indemnified hereunder for such Agent Indemnitee’s own gross negligence or willful misconduct, as determined by a court of competent jurisdiction, or to the extent that such claim relates to the breach by such Agent Indemnitee of its
obligations under this Agreement. The foregoing shall survive the termination of this Agreement. 

Section 9.8 Status of other Agents. Anything herein to the contrary notwithstanding, none of the bookrunner,
arranger, syndication agent or documentation agent listed on the cover page and page one hereof shall have any powers, duties or responsibilities under this Agreement (or the Notes and the Collateral Documents), except in its capacity, as
applicable, as the Agent, the Issuing Bank or a Lender hereunder. None of the bookrunner, arranger, syndication agent or documentation agent shall have or be deemed to have any fiduciary relationship with any Lender. Each Lender acknowledges that it
has not relied, and will not rely, on the bookrunner, arranger, syndication agent, or documentation agent in deciding to enter into this Agreement or in taking or not taking any action hereunder.

 Section 10.2 Entire Agreement.
This Agreement, the Notes and the Collateral Documents together with the letter agreement referred to in Subsection 2.5(d) set forth the entire agreement between the Borrower and the Agent and the Lenders with respect to the Indebtedness, and
supersede all prior written or oral understandings with respect thereto; provided, however, that all written representations, warranties and certifications made by the Borrower to the Agent and the Lenders with respect to the Indebtedness and the
security therefor shall survive the execution of this Agreement. The Borrower is not relying on any representation by the Agent or any Lender, and no representation has been made, that the Agent or any Lender will, at the time of a Default or at any
other time, waive, negotiate, discuss, or take or refrain from taking any action with respect to such Default. 

Section 10.3 Renewal, Extension or Rearrangement. All provisions of this Agreement relating to the Notes
shall apply with equal force and effect to each and all promissory notes or security instruments hereinafter executed which in whole or in part represent a renewal, extension for any period, increase or rearrangement of any part of the Notes.

prepayments, or (v) effect the release of any Collateral (other than as expressly permitted in the Collateral Documents or this Agreement) or subordinate the rights of the Agent and the Lenders with respect to Collateral, or (vi) reduce
the proportion of the Lenders required to agree on each determination of the Borrowing Base, or on which portion of the Collateral is Shared Collateral under Section 3.4, or (vii) reduce the proportion of the Lenders or the Required

(x) amend any provision of Section 2.15, or (xi) amend any provision of Section 6.21. No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the
Agent, and no amendment of any provision of this Agreement relating to the Issuing Bank issuing letters of credit shall be effective without the written consent of such Issuing Bank. However, the Agent may waive or reduce payment of its own fee
required under Section 2.5(d) or clause (v) of Subsection 9.6(a) without obtaining the consent of any of the Lenders. The Borrower, the Agent and the Lenders agree that no Lender will receive compensation from the Borrower in
order to obtain such Lender’s consent to an amendment or waiver in a greater proportion than that received by any other Lender for the same matter (but this provision does not restrict fees to the agents for their services in connection with
this Agreement). Notwithstanding any provision of this Section 10.4 to the contrary, if any Lender becomes a Defaulting Lender, then the provisions of Subsection 2.15(d) shall apply for so long as such Lender is a Defaulting
Lender. 
 Section 10.5 Invalidity. In the event that any one or more of the provisions contained in
this Agreement, the Notes, or the Collateral Documents shall, for any reason, be held invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not affect any other provision of this Agreement, the Notes
or the Collateral Documents. 
 Section 10.6 Survival of Agreements. All representations and
warranties of the Borrower herein, and all covenants and agreements herein not fully performed before the effective date of this Agreement, shall survive such date. 

Section 10.7 Waivers. No course of dealing on the part of the Agent, any Lender, its respective officers,
employees, consultants or agents, nor any failure or delay by the Agent or any Lender with respect to exercising any of its rights, powers or privileges under this Agreement, the Notes or the Collateral Documents, shall operate as a waiver thereof.

  
 -92-

 Section 10.8 Cumulative Rights. The rights and remedies of the
Agent and the Lenders under the Loan Documents shall be cumulative, and the exercise or partial exercise of any such right or remedy shall not preclude the exercise of any other right or remedy. 

Section 10.9 Time of the Essence. Time shall be deemed of the essence with respect to the performance of all
of the terms, provisions and conditions on the part of the Borrower, and the Agent and the Lenders to be performed hereunder. 
 Section 10.10 Successors and Assigns; Participants. All covenants and agreements made by or on behalf of the Borrower in the Loan Documents shall bind its successors and assigns and shall
inure to the benefit of the Agent and the Lenders and their respective successors and assigns. The Borrower may not assign its rights or obligations under this Agreement. 

Section 10.11 Relationship Between the Parties. The relationship between the Agent and the Lenders, on the
one hand, and the Borrower on the other, shall be solely that of lender and borrower, and such relationship shall not, under any circumstances whatsoever, be construed to be a joint venture, joint adventure, or partnership. Neither the Agent nor any
Lender has a fiduciary obligation to the Borrower with respect to this Agreement or the transactions contemplated hereby. 
 Section 10.12 Limitation of Liability. The Loan Documents are executed by officers of the Agent and the Lenders, and by acceptance of the Loan, the Borrower agrees that for the payment of any
claim or the performance of any obligations hereunder resulting from any default by the Agent or any of the Lenders, resort shall be had solely to the assets and property of the Agent or such Lender, and no shareholder, officer, employee or agent of
the defaulting Agent or Lender shall be personally liable therefor. 
 Section 10.13 Titles of Articles,
Sections and Subsections. All titles or headings to articles, sections, subsections or other divisions of this Agreement or the exhibits hereto are only for the convenience of the parties and shall not be construed to have any effect or meaning

dollars of the proceeds of the common stock offering and the Senior Unsecured Notes offering described in Section 11.4 in a restricted interest bearing deposit account with the Agent in the name of the Borrower on or before the Closing
Date. This restricted account and all proceeds, funds and investments therein shall be Collateral. The Borrower hereby grants to the Agent for the benefit of the Secured Parties a continuing security interest in this restricted account, as security
for the Secured Liabilities, and in all funds, investment property and proceeds pertaining thereto. The funds in the restricted account shall be used by the Borrower solely for the purpose of retiring a portion of the Borrower’s 2013
Convertible Debt, such that the 2013 Convertible Debt shall have an outstanding balance of no more than seventy-five million ($75,000,000.00) dollars within forty-five (45) days after the effective date of this Agreement under
Section 11.3. The Agent shall release the funds in such deposit account from time to time upon written request from the Borrower containing a certification that such funds will be used in compliance with this Section and the Agent shall
transfer all such funds in accordance with the Borrower’s instructions for use in accordance with this Section. If the 2013 Convertible Debt is not retired to an outstanding balance of no more than $75,000,000.00 within forty-five
(45) days after the effective date of this Agreement, then this restricted account and the remaining funds therein shall continue as Collateral for all purposes hereunder.

 ADDENDUM I 
 LIBO RATE PROVISIONS 
 1. The Agent shall determine the interest
rate applicable to LIBO Rate Advances, and its determination shall be conclusive in the absence of manifest error. The Agent shall endeavor to notify the Borrower prior to the date on which an interest payment is due, provided that the failure of
the Agent to provide such notice shall not affect the Borrower’s obligation to pay interest on such date. 

2. If any applicable law or regulation, or the action of any applicable regulatory requirement increases the reserves or
capital required to be maintained by any Lender or the Agent with respect to the Loan (including unfunded commitments and obligations on letter of credit), such Lender or the Agent shall promptly deliver a certificate to the Borrower specifying the
additional amount as will compensate such Lender or the Agent for the additional costs, which certificate shall be conclusive in the absence of manifest error. The Borrower shall pay the amount specified in such certificate promptly upon receipt.

 3. If the Agent gives notice to the Borrower that no LIBO bid rate is quoted to the Agent (or otherwise that
adequate and reasonable methods do not exist for ascertaining the LIBO Rate) for the applicable Interest Period or in the applicable amounts (which notice shall be conclusive and binding on the Borrower and the Lenders absent manifest error), then
(A) the obligation of the Agent and the Lenders to make a LIBO Rate Advance and the ability of the Borrower to select the LIBO Rate for an Advance shall be suspended, and (B) the Borrower shall either prepay all LIBO Rate Advances for
which an interest rate is to be determined on such date or the Loan shall thereafter bear interest at the Base Rate. 
 4. If any applicable domestic or foreign law, treaty, rule or regulation (whether now in effect or hereinafter enacted or promulgated, including Regulation D of the Board of Governors of the Federal
Reserve System) or any interpretation or administration thereof by any governmental authority charged with the interpretation or administration thereof (whether or not having the force of law): 

(i) changes the basis of taxation of payments to any Lender or the Agent or any principal, interest, or
other amounts attributable to any LIBO Rate Advance (other than taxes imposed on the overall net income of such Lender or the Agent); 
 (ii) changes, imposes, modifies, applies or deems applicable any reserve, special deposit or similar requirements in respect of any such LIBO Rate Advance (excluding those for which such Lender or the
Agent is fully compensated pursuant to adjustments made in the definition of LIBO Rate) or against assets of, deposits with or for the account of, or credit extended by, any Lender or the Agent; or 

 ADDENDUM I 
 PAGE - 2 - 
  

 (iii) imposes on any Lender or the Agent or the
interbank eurocurrency deposit and transfer market any other condition or requirement affecting any such LIBO Rate Advance, 

and the result of any of the foregoing is to increase the cost to such Lender or the Agent of funding or maintaining any such LIBO Rate
Advance (other than costs for which such Lender or the Agent is fully compensated pursuant to adjustments made in the definition of LIBO Rate) or to reduce the amount of any sum receivable by such Lender or the Agent in respect of any such LIBO Rate
advance by an amount deemed by such Lender or the Agent to be material, then such Lender or the Agent shall promptly notify the Borrower in writing of the happening of such event and (1) Borrower shall upon demand pay to such Lender or the
Agent such additional amount or amounts as will compensate such Lender or the Agent for such additional cost or reduction and (2) Borrower may elect, by giving to the Agent not less than three Business Days’ notice, to change the interest
rate applicable to such Advance, and any other portion of the Loan bearing interest at the LIBO Rate, to the Base Rate. 
 5. Notwithstanding any other provision hereof, if any change in applicable laws, treaties, rules or regulations or in the interpretation or administration thereof of or in any jurisdiction whatsoever,
domestic or foreign, shall make it unlawful or impracticable for any Lender to maintain Advances bearing interest at the LIBO Rate, or shall materially restrict the authority of any Lender to purchase, sell or take certificates of deposit or
offshore deposits of dollars, then, upon notice by such Lender to Borrower and the Agent, such Lender’s portion of all LIBO Rate Advances which are then outstanding and which cannot lawfully or practicably be maintained shall immediately cease
to bear interest at the LIBO Rate and shall commence to bear interest at the Base Rate. The Borrower agrees to indemnify each Lender and hold it harmless against all costs, expenses, claims, penalties, liabilities and damages which may result from
any such change in law, treaty, rule, regulation, interpretation or administration. The Borrower hereby agrees promptly to pay the Agent for the account of such Lender, upon demand by such Lender, any additional amounts necessary to compensate such
Lender for any costs incurred by such Lender in making any conversion in accordance with this Paragraph, including any interest or fees payable by such Lender to lenders of funds obtained by it in order to make or maintain hereunder its portion of
the Loan accruing interest based on the LIBO Rate. 
 6. The Borrower will indemnify the Agent and each Lender
against, and reimburse the Agent and each Lender on demand for, any loss or expense incurred or sustained by the Agent and each Lender (including without limitation, any loss or expense incurred by reason of the liquidation or reemployment of
deposits or other funds acquired by the Agent and each Lender to fund or maintain LIBO Rate Advances) as a result of (i) any payment or prepayment (whether authorized or required hereunder or otherwise) of all or a portion of any LIBO Rate
Advance on a day other than the day on which the applicable Interest Period ends, (ii) any payment or prepayment, whether required hereunder or otherwise, of the LIBO Rate Advances made after the delivery, but before the effective date, of an
election to have the LIBO Rate apply 

  

 ADDENDUM I 
 PAGE - 3 - 
  

 
to LIBO Rate Advance, if such payment or prepayment prevents such election from becoming fully effective, or (iii) the failure of any LIBO Rate Advance to be made by the Agent and each
Lender or of any such election to become effective due to any condition precedent to a LIBO Rate Advance not being satisfied or due to any other action or inaction of Borrower. For purposes of this section, funding losses arising by reason of
liquidation or reemployment of deposits or other funds acquired by the Agent or any Lender to fund or maintain LIBO Rate Advances shall be calculated as the remainder obtained by subtracting: (1) the yield (reflecting both stated interest rate
and discount, if any) to maturity of obligations of the United States Treasury as determined by the Agent or such Lender in an amount equal or comparable to such advance for the period of time commencing on the date of the payment, prepayment or
change of rate as provided above and ending on the last day of the subject Interest Period, from (2) the LIBO Rate of the subject Interest Period, times the number of days from the date of payment, prepayment or change of rate to the
last day of the subject Interest Period, divided by 360. Any payment due under this paragraph will be paid to the Agent or such Lender within five days after demand therefor by the Agent or such Lender. 

7. The Borrower covenants and agrees that: 

(i) The Borrower will pay, within five days after notice thereof from Agent (on behalf of itself or any
Lender) and on an after-tax basis, all present and future income, stamp and other taxes, levies, costs and charges whatsoever imposed, assessed, levied or collected on or in respect of any LIBO Rate Advance whether or not legally or correctly
imposed, assessed, levied or collected (excluding taxes, levies, costs or charges imposed on or measured by the overall net income of the Agent or any Lender) (all such non-excluded taxes, levies, costs and charges being collectively called
“Reimbursable Taxes”). Promptly after the date on which payment of any Reimbursable Taxes is due pursuant to applicable law, the Borrower will, at the request of the Agent, furnish to the Agent evidence in form and substance
satisfactory to the Agent that Borrower has met its obligation under this paragraph. 
 (ii) The
Borrower will indemnify the Agent and each Lender against, and reimburse the Agent and each Lender on demand for, any Reimbursable Taxes paid by the Agent or such Lender and any loss, liability, claim or expense, including interest, penalties and
legal fees, that the Agent and each Lender may incur at any time arising out of or in connection with the failure of Borrower to make any payment of Reimbursable Taxes when due, unless such failure is due to Agent or such Lender’s failure to
give notice to Borrower of Borrower’s obligation to pay such Reimbursable Taxes at least five days prior to the date when they are due. Any payment due under this subsection will be paid to the Agent or such Lender within five days after demand
therefor by the Agent or such Lender. 

  

 ADDENDUM I 
 PAGE - 4 - 
  

 (iii) All payments on account of the principal of, and
interest on, LIBO Rate Advances and all other amounts payable by Borrower to the Agent and the Lenders hereunder shall be made free and clear of and without reduction by reason of any Reimbursable Taxes. 

(iv) If Borrower is ever required to pay any Reimbursable Taxes with respect to any LIBO Rate Advance,
Borrower may elect, by giving to the Agent not less than three (3) Business Days’ notice, to change the interest rate applicable to any such advance from the LIBO Rate to the Base Rate, but such election shall not diminish Borrower’s
obligation to pay all Reimbursable Taxes therefore imposed, assessed, levied or collected.

 PROMISE TO
PAY. GMX RESOURCES INC. (“Borrower”), an Oklahoma corporation, promises to pay to the order of                  (“Lender”) at the office
of Capital One, National Association (“Agent”) at 5718 Westheimer, Houston, Texas, in lawful money of the United States of America, the sum of
                 and 00/100 dollars (U.S. $        ), or such other or lesser amount as from time to time equals
the aggregate unpaid principal balance of loan advances made to Borrower by Lender on a revolving line of credit basis as provided below, together with simple interest assessed on the variable rate(s) basis provided below, with interest being
assessed on the unpaid principal balance of this Note as outstanding from time to time, commencing on the date hereof and continuing until this Note is paid in full. Interest on Base Rate Advances under this Note shall be calculated on the basis of
a 365 (or in a leap year 366) day year and the actual number of days elapsed, and interest on LIBO Rate Advances under this Note shall be calculated on a 365/360 simple interest basis, that is, by applying the ratio of the annual interest rate over
a year of 360 days, times the outstanding principal balance, times the actual number of days the principal balance is outstanding. 
 LOAN AGREEMENT. This Note is a Note referred to in and executed pursuant to that certain fifth amended and restated loan agreement dated as of February 2, 2011 among Borrower, Agent and the
lenders from time to time party thereto (as amended, renewed or restated from time to time, the “Loan Agreement”), and is entitled to the benefits thereof. Unless otherwise defined herein, each capitalized term used herein shall have the
same meaning set forth in the Loan Agreement. The Maturity Date is further defined in the Loan Agreement, including provision for an earlier date of maturity upon certain conditions. Reference is made to the Loan Agreement

  

 EXHIBIT A 
 PAGE - 2 - 
  

 
for provisions for the acceleration of the maturity hereof on the occurrence of certain events specified therein, for mandatory prepayments required of the Borrower in certain circumstances, and
for all other pertinent provisions. 
 LINE OF CREDIT. This Note evidences revolving line of credit advances that may be
made from time to time to Borrower under the Loan Agreement (including loan advances arising from draws on standby letters of credit issued thereunder). Borrower agrees to be liable for all sums either (a) advanced in accordance with the
instructions of an authorized person as specified in the Loan Agreement or (b) credited pursuant to the Loan Agreement to any of Borrower’s deposit accounts with Agent. The unpaid principal balance owing on this Note at any time may be
evidenced by endorsements on this Note or by Agent’s or Lender’s internal records, including daily computer print-outs. Advances shall only be made in accordance with the terms and conditions of the Loan Agreement. 

PAYMENT. Borrower will pay interest on Base Rate Advances at the Base Rate monthly in arrears on the last day of each successive
calendar month, but in no event greater than the Maximum Rate (as such term is defined in the Loan Agreement). Borrower will pay interest on LIBO Rate Advances at the applicable LIBO Rate on the last day of each applicable LIBO Rate Interest Period
for each LIBO Rate Advance, but in no event greater than the Maximum Rate. Borrower will pay the balance of all outstanding principal on this Note, together with all accrued but unpaid interest, at the Maturity Date. Borrower will pay Lender at

that such payment is required, or otherwise is, to be made. Any payment received and accepted by Lender after such time shall be considered for all purposes (including the calculation of interest to the extent permitted by law) as having been made
on the next following Business Day. Whenever any payment to be made hereunder falls on a day other than a Business Day, then unless otherwise provided in the Loan Agreement such payment shall be made on the next succeeding Business Day (without
penalty or default), and such extension of time shall in each case be included in the calculation of interest. Unless otherwise agreed or required by applicable law, payments will be applied first to accrued unpaid interest, then to principal, and
any remaining amount to any unpaid collection costs and late charges. 
 VARIABLE INTEREST RATES. This Note bears
interest on and after the date hereof to and including the Maturity Date at the variable rate(s) per annum equal to the Base Rate or LIBO Rate, as selected by Borrower in accordance with the Loan Agreement, but in no event greater than the Maximum
Rate. The interest rate on this Note is subject to change from time to time based on changes in the Prime Rate and the LIBO Rate. If the index rate used in determining the Prime Rate becomes unavailable during the term of this Note, Agent may
designate a substitute index after notice to Borrower. Agent will tell Borrower the Prime Rate upon Borrower’s request. Borrower understands that Lender may make loans based on other rates as well. The

  

 EXHIBIT A 
 PAGE - 3 -

principal balance of this Note shall bear interest from and after an Event of Default or the Maturity Date until paid at the Default Rate from time to time in effect. 
 PREPAYMENT. Borrower may prepay this Note in full or in part at any time by paying the then unpaid principal balance of this Note, plus accrued simple interest and any unpaid late charges through

Agreement. If Borrower prepays this Note in full, or if Lender accelerates payment, Borrower understands that, unless otherwise required by law, any prepaid fees or charges will not be subject to rebate and will be earned by Lender at the time this
Note is signed. 
 LATE CHARGE. If Borrower fails to pay any payment under this Note in full within ten (10) days of
when due, Borrower agrees to pay Lender a late payment fee in an amount equal to 5.000% of the delinquent interest due. Late charges will not be assessed following declaration of default and acceleration of maturity of this Note. 

DEFAULT. If any Event of Default occurs, Agent and Lender shall have all the rights and remedies (including acceleration of the
Maturity Date of this Note) available to them pursuant to the Loan Agreement or applicable law. 
 ATTORNEYS’ FEES.
If Lender refers this Note to an attorney for collection, or files suit against Borrower to collect this Note, or if Borrower files for bankruptcy or other relief from creditors, Borrower agrees to pay Agent’s and Lender’s reasonable
attorneys’ fees. 
 DEPOSIT ACCOUNTS. As collateral security for repayment of this Note and all renewals and
extensions, as well as to secure any and all Indebtedness that Borrower may now or in the future owe to Agent or any Lender in connection with the Loan Agreement, Borrower hereby grants Agent for itself and the ratable benefit of the Lenders a
continuing security interest in any and all funds that Borrower may now and in the future have on deposit with Agent or in certificates of deposit or other deposit accounts as to which Borrower is an account holder (with the exception of IRA,
pension, and other tax-deferred deposits). 
 COLLATERAL. This Note is secured by the Collateral and Collateral Documents
as provided in the Loan Agreement. 
 WAIVERS. Borrower and each guarantor of this Note hereby waive presentment for
payment, protest, notice of protest and notice of nonpayment, and all pleas of division and discussion, and severally agree that their obligations and liabilities to Lender hereunder shall be on a “solidary” or “joint and
several” basis. Borrower and each guarantor further severally agree that discharge or release of any party who is or may be liable to Lender for the indebtedness represented hereby, 

  

 EXHIBIT A

or the release of any collateral directly or indirectly securing repayment hereof, shall not have the effect of releasing any other party or parties, who shall remain liable to Lender, or of
releasing any other collateral that is not expressly released by Lender. Borrower and each guarantor additionally agree that Lender’s acceptance of payment other than in accordance with the terms of this Note, or Lender’s subsequent
agreement to extend or modify such repayment terms, or Lender’s failure or delay in exercising any rights or remedies granted to Lender, shall likewise not have the effect of releasing Borrower or any other party or parties from their
respective obligations to Lender, or of releasing any collateral that directly or indirectly secures repayment hereof. In addition, any failure or delay on the part of Lender to exercise any of the rights and remedies granted to Lender shall not
have the effect of waiving any of Lender’s rights and remedies. Any partial exercise of any rights and/or remedies granted to Lender shall furthermore not be construed as a waiver of any other rights and remedies; it being Borrower’s
intent and agreement that Lender’s rights and remedies shall be cumulative in nature. A waiver or forbearance on the part of Lender as to one event of default shall not be construed as a waiver or forbearance as to any other default. Borrower
and each guarantor of this Note further agrees that any late charges provided for under this Note will not be charges for deferral of time for payment and will not and are not intended to compensate Lender for a grace or cure period, and no such
deferral, grace or cure period has been or will be granted to Borrower in return for the imposition of any late charge. Borrower recognizes that Borrower’s failure to make timely payment of amounts due under this Note will result in damages to
Lender, including but not limited to Lender’s loss of the use of amounts due, and Borrower agrees that any late charges imposed by Lender hereunder will represent reasonable compensation to Lender for such damages. Failure to pay in full any
installment or payment timely when due under this Note, whether or not a late charge is assessed, will remain and shall constitute an event of default hereunder. 
 SUCCESSORS AND ASSIGNS LIABLE. Borrower’s and each guarantor’s obligations and agreements under this Note shall be binding upon Borrower’s and each guarantor’s respective
successors, heirs, legatees, devisees, administrators, executors and assigns. The rights and remedies granted to Lender under this Note shall inure to the benefit of Lender’s successors and assigns, as well as to any subsequent holder or
holders of this Note. 
 CAPTION HEADINGS. Caption headings of the sections of this Note are for convenience purposes
only and are not to be used to interpret or to define their provisions. In this Note, whenever the context so requires, the singular includes the plural and the plural also includes the singular. 

WAIVER OF JURY TRIAL. LENDER AND BORROWER HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION,
PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE OTHER.
