diligently endeavor to cure any defect that may be claimed, and Grantor will take all necessary and proper steps for the defense of such legal proceedings, including the employment of counsel reasonably acceptable to Beneficiary, the prosecution or
defense of litigation and the release or discharge of all adverse claims. The Trustee and Beneficiary, or either of them (whether or not named as parties to legal proceedings with respect thereto), are hereby authorized and empowered to take such
additional steps as in their reasonable judgment and discretion may be necessary or proper for the defense of any such legal proceedings, including the prosecution or defense of litigation, and the compromise or discharge of any adverse claims made

Section 12.03(a) of the Credit Agreement.

Grantor’s obligations under and maintain all Subject Leases, Subject Contracts, and Subject Easements in full force and effect, and Grantor will not permit to occur the surrender, abandonment, release, or termination of any Subject Lease,

maintained, with a financially sound and reputable insurer, flood insurance in an amount sufficient to comply with all applicable Flood Insurance Regulations applicable to the Mortgaged Property, if any. 

ARTICLE 3 
 DEFAULTS
AND REMEDIES 
 Section 3.1 Defaults. The term “default” as used herein shall mean an
Event of Default under the Credit Agreement. 
 Section 3.2 Remedies. If a default shall occur and be continuing,
Beneficiary may, at its option, do any one or more of the following to the extent permitted by applicable Law: 
 (a) Payment or
Performance by Beneficiary. If Grantor has failed to keep or perform any covenant whatsoever contained in this Deed of Trust or any other security instrument, Beneficiary may, but shall not be obligated to any Person to do so, perform or attempt
to perform such covenant, and any payment made or expense incurred in the performance or attempted performance of any such covenant shall be a part of the Obligation, and Grantor promises, upon demand, to pay to Beneficiary, at the place where the
Notes are payable, or at such other place as Beneficiary may direct by written notice, all sums so advanced or paid by Beneficiary, with interest at the Highest Lawful Rate, from the date when paid or incurred by Beneficiary until paid by Grantor.
No such payment by Beneficiary shall constitute a waiver of any default. In addition to the Liens hereof, Beneficiary shall be subrogated to all rights and Liens securing the payment of any debt, claim, tax, or assessment for the payment of which
Beneficiary may make an advance, or which Beneficiary may pay. 
 (b) Acceleration. Beneficiary may, at its option, declare the
aggregate unpaid principal amount of and interest on the Notes and all other parts of the Obligation (other than liabilities under any Secured Swap Agreements or any Secured Cash Management Agreement) to be, and the same shall thereupon become
immediately due and payable without presentment, demand, protest, notice of acceleration, notice of intent to accelerate, notice of protest or notice of dishonor, or any other notice of any kind, all of which are expressly waived by Grantor. 

(c) Foreclosure. Beneficiary may request Trustee to proceed with foreclosure, and in such event Trustee is hereby authorized and
empowered, and it shall be such Person’s duty, upon such request of Beneficiary, and to the extent permitted by applicable Law, to sell all or any part of the Mortgaged Property at one or more sales, as an entirety or in parcels, at such place
or places and otherwise in such manner and upon such notice as may be required by applicable Law, or in the absence of any such requirement, as Trustee and/or Beneficiary may deem appropriate, and to make conveyance to the purchaser or purchasers
thereof. Any sale of any part of the Mortgaged Property shall be made to the highest bidder or bidders for cash, at the courthouse door of, or at such other place as may be required or permitted by applicable Law in, the county (or judicial
district) wherein the Lands included within the Mortgaged Property to be sold are situated; provided that if the Lands are situated in more than one county (or judicial district), such sale of the Mortgaged Property, or any part thereof, may
be made in any county (or judicial district) wherein any part of the Lands included within the Mortgaged Property to be sold are situated. Any such sale shall be made at public outcry, on the day of any month, during the hours of such day and after
written notices thereof have been publicly posted in such places and for such time periods and after all Persons entitled to notice thereof have been sent such notice, all as required by applicable Law in effect at the time of such sale. Nothing
herein shall be deemed to require Beneficiary or Trustee to do, and Beneficiary and Trustee shall not be required to do, any act other than as required by applicable Law in effect at the time of such sale. Any such sale may be as a whole or in such
parcels as Trustee may select. After such sale, Trustee shall make to the purchaser or purchasers thereunder good and sufficient deeds and assignments, in the name of Grantor, conveying the Mortgaged Property, or part thereof, so sold to the
purchaser or purchasers with general warranty of title (subject to Permitted Liens) by Grantor. Sale of a part of the Mortgaged Property shall not exhaust the power of sale, but sales may be made from time to time until the Obligation is paid and
performed 

  
 DEED OF TRUST – Page 7

 in full. It shall not be necessary to have present or to exhibit at any such sale any of the Collateral. In
addition to the rights and powers of sale granted under the preceding provisions of this Section 3.2(c), if default is made in the payment of any installment of the Obligation, Beneficiary, at its option, at once or at any time thereafter
while any matured installment remains unpaid, without declaring the entire Obligation to be due and payable may orally or in writing direct Trustee to enforce this trust and to sell the Mortgaged Property subject to such unmatured Obligation and the
Liens securing its payment, in the same manner, on the same terms, at the same place and time, and after having given notice in the same manner, all as provided in the preceding provisions of this Section 3.2(c). After such sale, Trustee
shall make due conveyance to the purchaser or purchasers. Sales made without maturing the Obligation may be made hereunder whenever there is a default in the payment of any installment of the Obligation without exhausting the power of sale granted
hereby, and without affecting in any way the power of sale granted under this Section 3.2(c) on the unmatured balance of the Obligation (except as to any proceeds of any sale which Beneficiary may apply as a prepayment on the Obligation) or
the Liens securing payment of the Obligation. It is intended by each of the foregoing provisions of this Section 3.2(c) that Trustee may, after any request or direction by Beneficiary, sell, not only the Subject Interests included within, but
also, all other items constituting a part of, the Mortgaged Property, or any part thereof, along with the Lands, or any part thereof, included within the Mortgaged Property all as a unit and as a part of a single sale, or may sell any part of the
Mortgaged Property separately from the remainder of the Mortgaged Property. It is agreed that, in any deed or assignment given by Trustee, any and all statements of fact or other recitals therein made as to the identity of Beneficiary, or as to the
occurrence or existence of any default, or as to the acceleration of the maturity of the Obligation, or as to the request to sell, notice of sale, time, place, terms and manner of sale, and the receipt, distribution and application of the money
realized therefrom, or as to the due and proper appointment of a substitute trustee, and, without being limited by the foregoing, as to any other act or thing having been duly done by Beneficiary or by Trustee, shall be taken by all courts of Law
and equity as prima facie evidence that the said statements or recitals state facts, and Grantor does hereby ratify and confirm any and all acts that Trustee may lawfully do in the premises by virtue hereof. In the event of the
resignation (such resignation being hereby authorized for any reason) or death of Trustee or such Person’s failure, refusal or inability, for any reason, to make any such sale or to perform any of the trusts herein declared, or, at the option
of Beneficiary, without cause, Beneficiary may appoint, in writing, a substitute trustee, who shall thereupon succeed to all the estates, titles, rights, powers and trusts herein granted to and vested in Trustee. Such appointment may be made on
behalf of Beneficiary by any Person who is then the president, or any vice president, or a senior representative, or any other authorized officer or agent of Beneficiary. In the event of the resignation (such resignation being hereby authorized for
any reason) or death of any such substitute trustee, or such Person’s failure, refusal or inability to make such sale or perform such trusts, or, at the option of Beneficiary, without cause, successive substitute trustees may thereafter, from
time to time, be appointed by Beneficiary in the same manner. Trustee may appoint, in writing, any one or more Persons as Trustee’s agent and attorney-in-fact to
act as Trustee under him and in Trustee’s name, place and stead, to perform any one or more acts necessary or incident to any sale under the power of sale granted under the preceding provisions of this Section 3.2(c), including the
posting and filing of any notices, the conduct of such sale and the execution and delivery of any instruments conveying the Mortgaged Property so sold, but in the name and on behalf of Trustee. All acts done or performed by any such agent and attorney-in-fact shall be valid, lawful and binding as if done or performed by Trustee. 

(d) Suit. Beneficiary may proceed by suit or suits, at Law or in equity, to enforce the payment and performance of the Obligation in
accordance with the terms hereof, of the Notes or the other security instruments, or other documents and/or writings securing and/or evidencing the Obligation, to foreclose the Liens of this Deed of Trust as against all or any part of the Mortgaged
Property and to have all or any part of the Mortgaged Property sold under the judgment or decree of a court of competent jurisdiction. 

(e) Appointment of Receiver. Beneficiary, as a matter of right and without regard to the sufficiency of the security, and without any
showing of insolvency, fraud or mismanagement on the part of Grantor, and without the necessity of filing any judicial or other proceeding other than the proceeding for appointment of a receiver, shall be entitled to the appointment of a receiver or
receivers of the Mortgaged Property, or any part thereof, and of the income, rents, issues and profits thereof. 

  
 DEED OF TRUST – Page 8

 (f) Possession of Mortgaged Property. Beneficiary may enter upon the Lands included within
the Mortgaged Property, take possession of the Mortgaged Property, and remove the Personal Property included within the Mortgaged Property, or any part thereof, with or without any responsibility or liability on the part of Beneficiary, and may take
possession of any property located on or in the Mortgaged Property which is not a part of the Mortgaged Property and hold or store such property at Grantor’s expense. 

(g) Assemble Collateral. Beneficiary may require Grantor to assemble the Collateral included within the Mortgaged Property, or any part
thereof, and make it available to Beneficiary at a place to be designated by Beneficiary which is reasonably convenient to Grantor and Beneficiary. 

(h) Disposition of Collateral. After notification, if any, as hereafter provided in this Section 3.2(h),
Beneficiary may sell, lease or otherwise dispose of, at the office of Beneficiary, or on the Lands, or elsewhere, as chosen by Beneficiary, all or any part of the personal property Collateral included within the Mortgaged Property, in its then
condition, or following any commercially reasonable preparation or processing, and each sale (as used in this Section 3.2(h), the term “sale” means any such sale, lease, or other disposition made pursuant to this
Section 3.2(h)) may be a unit or in parcels, by public or in private proceedings, and by way of one or more contracts, and, at any sale, it shall not be necessary to exhibit such Collateral, or part thereof, being sold, leased or otherwise
disposed of. The sale of any part of the Collateral shall not exhaust Beneficiary’s power of sale, but sales may be made from time to time until the Obligation is paid and performed in full. Reasonable notification of the time and place of any
public sale pursuant to this Section 3.2(h), or reasonable notification of the time after which any private sale is to be made pursuant to this Section 3.2(h), shall be sent to Grantor and to any other Person entitled under the
applicable Code to notice. To the extent any sale is conducted pursuant to the Code, it is agreed that notice sent or given not less than ten (10) calendar days prior to the taking of the action to which the notice relates is reasonable
notification and notice for such purposes of this Section 3.2(h). 
 (i) Surrender of Insurance Policies. Beneficiary may
surrender the insurance policies maintained pursuant to the Credit Agreement, or any part thereof, and receive and apply the unearned premiums as a credit on the Obligation, and, in connection therewith, Grantor hereby appoints Beneficiary as the
agent and attorney-in-fact for Grantor to collect such premiums (which appointment is coupled with an interest and irrevocable while this Deed of Trust is in effect).

 Section 3.3 Purchase of Mortgaged Property by Beneficiary. If Beneficiary or any Secured Party is the purchaser of the
Mortgaged Property, or any part thereof (and it is specifically agreed that Beneficiary or any Secured Party may be the purchaser of the Mortgaged Property, or any part thereof, if permitted by applicable Law), at any sale thereof, whether such sale
be under the power of sale hereinabove vested in Trustee, or upon any other foreclosure of the Liens hereof, or otherwise, Beneficiary or the relevant Secured Party, as the case may be, shall, upon any such purchase, acquire good title to the
Mortgaged Property so purchased, free of the Liens of these presents. 
 Section 3.4 Operation of Properties by
Beneficiary. Should any part of the Mortgaged Property come into the possession of Beneficiary, whether before or after default, Beneficiary may use or operate (to the extent allowed under applicable operating arrangements) the Mortgaged
Property for the purpose of preserving it or its value, pursuant to the order of a court of appropriate jurisdiction, or in accordance with any other rights held by Beneficiary in respect to the Mortgaged Property. Grantor covenants promptly to
reimburse and pay to Beneficiary, at the place where Notes are payable, or at such other place as may be designated by Beneficiary in writing, the amount of all expenses (including the cost of any insurance, taxes, reasonable attorneys’ fees
and other charges) incurred by Beneficiary in connection with its custody, preservation, use or operation of the Mortgaged Property, together with interest thereon from the date incurred by Beneficiary at the Highest Lawful Rate, and all such
expenses, cost, taxes, interest and other charges shall be a part of the Obligation. It is agreed, however, that the risk of loss or damage to the Mortgaged Property is on Grantor, and Beneficiary shall have no liability whatever for decline or
diminution in value of the Mortgaged Property, nor for failure to obtain or maintain insurance, nor for failure to determine whether any insurance ever in force is adequate as to amount or as to the risks insured, except to the extent such loss or
damage results from the gross negligence or willful misconduct of Beneficiary, as determined by a court of competent jurisdiction by a final and non-appealable judgment. 

  
 DEED OF TRUST – Page 9

 Section 3.5 Possession of Property After Foreclosure. In case the Liens hereof
shall be foreclosed by Trustee’s sale, or by other judicial or non-judicial action, the purchaser at any such sale shall receive, as an incident to his ownership, immediate possession of the Mortgaged
Property, or any part thereof so conveyed, and, subsequent to foreclosure, Grantor and Grantor’s successors shall be considered as tenants at sufferance of the purchaser at foreclosure sale, and anyone occupying the property after demand made
for possession thereof shall be guilty of forcible detainer and shall be subject to eviction and removal, forcible, or otherwise, with or without process of Law, and all damages by reason thereof are hereby expressly waived. 

Section 3.6 Application of Proceeds. The proceeds from any sale, lease or other disposition made pursuant to this
Article 3, any proceeds of Hydrocarbons collected by Beneficiary pursuant to Article 4, and sums received pursuant to Section 6.5 shall be applied by Trustee, or by Beneficiary, as the case may be, first to
the payment of any and all expenses incurred by Trustee or Beneficiary in foreclosing upon the Property and carrying out such sale (including any attorneys’ fees), second to the payment of any fees assessed by Trustee, and third to the payment
or prepayment of the Obligation, whether or not matured, all in accordance with the Credit Agreement; provided, however, that notwithstanding the foregoing or anything to the contrary herein or in any other Loan Document, no such
proceeds shall be applied to any Excluded Swap Obligations. 
 Section 3.7 Abandonment of Sale. In the event a
foreclosure hereunder should be commenced by Trustee in accordance with Section 3.2(c), Beneficiary may at any time before the sale direct Trustee to abandon the sale, and exercise any other remedies available to Beneficiary. 

Section 3.8 Waiver of Appraisement and Redemption. To the full extent Grantor may lawfully do so, Grantor agrees that
Grantor will not at any time insist upon, plead, claim or take the benefit or advantage of any appraisement, valuation, stay, extension or redemption Laws, now or hereafter in force, in order to prevent or hinder the enforcement of this Deed of
Trust or the absolute sale of the Mortgaged Property or any part thereof, or the possession thereof by any purchaser at any such sale, and Grantor, insofar as Grantor now or hereafter may lawfully do so, hereby waives the benefit of all such Laws;
provided, however, that the appraisement of any of the Mortgaged Property is hereby expressly waived or not waived at the option of Beneficiary, such option to be exercised prior to or at the time judgment is rendered in any foreclosure of
this Deed of Trust. Grantor also expressly waives, to the extent Grantor may lawfully do so, all rights to have the Mortgaged Property marshaled upon any foreclosure of this Deed of Trust. 

ARTICLE 4 

ASSIGNMENT OF PRODUCTION 

Section 4.1 Assignment and Additional Security. In addition to the conveyance to Trustee herein made and to additionally
secure the Obligation, Grantor has, effective as of 7:00 o’clock a.m., local time, on the first day of the month in which this Deed of Trust is executed, at the site of each of the Subject Leases, ASSIGNED, TRANSFERRED AND CONVEYED, and does
hereby ASSIGN, TRANSFER AND CONVEY, unto Beneficiary all of the following: 
 (a) All Hydrocarbons, and the proceeds therefrom and products
obtained or processed therefrom (such proceeds and products being herein called “Proceeds”), produced and to be produced from the Mortgaged Property, and all rights of Grantor to Liens securing payment of Proceeds, including
those Liens provided for in §9.343 of the Code. Grantor hereby authorizes and empowers Beneficiary, during the existence of a default, to demand, collect and receive such Hydrocarbons and Proceeds, to endorse and cash any checks and drafts
payable to Grantor or Beneficiary for the account of Grantor received from or in connection with such Hydrocarbons and Proceeds, to execute any release, receipt, division order, transfer order, and relinquishment or other instrument that may be
required or necessary to collect and receive such Hydrocarbons and Proceeds, and to exercise any rights as the holder of Liens securing payment of Proceeds. Grantor hereby authorizes and directs all pipeline companies, gathering companies, and
others purchasing such Hydrocarbons or having in their possession any 

  
 DEED OF TRUST – Page 10

 
such Hydrocarbons or Proceeds, to pay and deliver to Beneficiary all such Hydrocarbons and Proceeds upon the written request of Beneficiary during the existence of a default; provided that
Grantor does hereby specifically agree that all such pipeline companies, gathering companies and others purchasing or having in their possession such Hydrocarbons and Proceeds shall be entitled to rely, and shall be fully protected in relying upon,
notice by Beneficiary that a default exists. Grantor agrees that all division orders, transfer orders, receipts and other instruments which Beneficiary may from time to time execute and deliver for the purpose of collecting or receipting for
Hydrocarbons or Proceeds may be relied upon in all respects and that the same shall be binding upon Grantor and Grantor’s successors. Grantor agrees to execute and deliver all necessary, convenient and appropriate instruments, including
transfer and division orders, which may be required by Beneficiary in connection with the receipt by Beneficiary of such Hydrocarbons or Proceeds and to indemnify and keep and hold Beneficiary free and harmless from all parties whomsoever having or
claiming an adverse interest in such Hydrocarbons and Proceeds and in this respect agrees to pay all expenses, costs, charges and attorneys’ fees that may be incurred by Beneficiary as to any of such matters. 

(b) All proceeds hereafter payable to or to become payable to Grantor or to which Grantor is entitled under all gas sales or exchange
contracts, all oil, distillate, or condensate sales or exchange contracts, all gas transportation contracts, and all gas processing contracts now or hereafter to become a part of the Mortgaged Property. 

(c) All amounts, sums, revenues, income and proceeds which become payable to Grantor from any of the Mortgaged Property (including any
after-acquired properties) or under any contract, present or future, relating to, any gas pipeline system and processing plant or unit now or hereafter constituting a part of the Mortgaged Property. 

(d) All lease bonus, delay rentals, royalties and shut-in gas royalties which become payable to
Grantor from any of the Mortgaged Property. 
 Section 4.2 Transfer Orders. Grantor agrees to execute such transfer
orders, payment orders, division orders and other instruments as may be needed by Beneficiary or requested by it incident to its having all assigned payments made direct to it. Grantor authorizes and directs all such pipeline companies, purchasers,
transporters and other parties owing moneys to Grantor under contracts herein assigned to pay such amounts direct to Beneficiary upon the written request by Beneficiary during the existence of a default as follows: 

Compass Bank, as Administrative Agent 

2200 Post Oak Boulevard, 17th Floor 

Houston, Texas 77056 
 and such
authorization shall continue until this Deed of Trust is released. During the existence of a default, Beneficiary is authorized to collect, receive, and give receipt for all such amounts, and no party making payment shall have any responsibility to
see to the application of any funds paid to Beneficiary but shall be fully protected in making such payment to Beneficiary under the assignments herein contained. Should Beneficiary bring suit against any third party for collection of any amounts or
sums included within this assignment (and Beneficiary shall have the right to bring any such suit), it may sue either in its own name or in the name of Grantor. 

Section 4.3 Payment of Proceeds. In the event that, for its convenience, Beneficiary should elect with respect to
particular properties or contracts not to exercise immediately its right to receive Hydrocarbons or proceeds, then the purchasers or other Persons obligated to make such payment shall continue to make payment to Grantor until such time as written
demand has been made upon them by Beneficiary or Trustee that payment be made directly to Beneficiary. Such failure to notify shall not in any way waive the right of Beneficiary to receive any payments not theretofore paid out to Grantor before the
giving of written notice. In this regard, in the event payments are made directly to Beneficiary, and then, at the request of Beneficiary payments are, for a period of time, paid to Grantor, Beneficiary shall nevertheless have the right, effective
upon written notice, to require that future payments be again made to Beneficiary. 

  
 DEED OF TRUST – Page 11

 Section 4.4 Proceeds Held in Trust by Grantor. If under any existing gas sales
or exchange agreements or products sales or exchange contracts, other than division orders or transfer orders, or under any gas transportation contract, any proceeds are required to be paid by the purchaser or transporter direct to Grantor so that
under such existing agreements payment cannot be made to Beneficiary in the absence of foreclosure, then Grantor’s interest in all proceeds under such sales agreement and in all other proceeds which for any reason may be paid to Grantor shall,
when received by Grantor during the existence of a default, constitute trust funds in his hands and shall be immediately paid over to Beneficiary, if Beneficiary has requested that such payments be delivered to it under this assignment. 

Section 4.5 Limitation of Liability of Beneficiary and Trustee. Beneficiary is hereby absolved from all liability for
failure to enforce collection of the proceeds and amounts assigned under Section 4.1 above and from all other responsibility in connection therewith, except the responsibility to account to the Person legally entitled
thereto (by application upon the Obligation or otherwise) for funds actually received. Grantor agrees to indemnify and hold harmless Trustee and Beneficiary against any and all liabilities, actions, claims, judgments, costs, charges, and
attorneys’ fees by reason of the assertion that they or either of them have received, either before or after payment and performance in full of the Obligation, funds from the production of Hydrocarbons claimed by third Persons, and Trustee and
Beneficiary shall each have the right to compromise and adjust any such claims, actions, and judgments, and in addition to the rights to be indemnified as herein provided, all amounts paid by Trustee or by Beneficiary in compromise, satisfaction, or
discharge of any such claim, action or judgment, and all court costs, attorneys’ fees, and other expenses of every character incurred by Trustee or by Beneficiary, pursuant to the provisions of this Section, shall be demand obligations owing by
Grantor and shall bear interest at the Highest Lawful Rate from date of expenditure until paid and shall be secured by the Liens created and granted by this Deed of Trust. 

Section 4.6 Duty to Pay Obligation. Nothing contained herein shall limit Grantor’s absolute duty to make
payment when due of the Obligation when the Proceeds received by Beneficiary pursuant to Section 4.1 hereof are insufficient to pay the same, and receipt of Proceeds under said Section 4.1 shall be
in addition to all other security now or hereafter existing to secure payment of the Obligation. 
 Section 4.7 Power of Attorney
to Beneficiary. Grantor does hereby designate Beneficiary as the agent of Grantor to act in the name, place and stead of Grantor for the purpose of taking any and all actions deemed by Beneficiary necessary for the realization by Beneficiary
of the benefits of the assignment of Proceeds provided herein, recognizing such agency in favor of Beneficiary to be coupled with the interests of Grantor under this Deed of Trust and, thus, irrevocable as long as this Deed of Trust is in force and
effect. All Persons dealing with Beneficiary, or any officer thereof, or any substitute, shall be fully protected in treating the powers and authorities conferred by this Section as continuing in full force and effect until advised by Beneficiary
that the entire Obligation is fully and finally paid.

time during the existence of a default notify the account debtors or obligors of any accounts, chattel paper, negotiable instruments or other evidences of indebtedness included in the Collateral to pay Beneficiary directly. 

Section 5.4 Filing of Financing Statement. Beneficiary shall have the right, without the consent or joinder of Grantor, to
execute and file with any Governmental Authority such financing statements, financing statement amendments and continuation statements as may, in the sole discretion of Beneficiary, be necessary or advisable to maintain, perfect or otherwise
evidence the Lien of Beneficiary in and to any of the Mortgaged Property. Grantor, as debtor, hereby expressly authorizes Beneficiary, as secured party, to file any such financing statement without the signature of Grantor to the extent permitted by
applicable Law.

 DEED OF
TRUST, MORTGAGE, ASSIGNMENT, SECURITY AGREEMENT 
 AND FINANCING STATEMENT, 

DATED AS OF MAY 5, 2017 

FROM PRIMEENERGY CORPORATION 

TO DOROTHY E. MARCHAND, TRUSTEE 

FOR COMPASS BANK, ADMINISTRATIVE AGENT 

This Exhibit A contains a description of those Subject Leases and Lands referred to in the foregoing Deed of Trust. The Subject Leases
and Lands consist of producing and non-producing oil and gas leases, oil, gas and mineral interests, oil and gas royalty interests, and oil and gas overriding royalty interests affecting lands situated in the
State of Texas in each of the counties listed on the cover page of this Deed of Trust, together with all of Grantor’s interest in all leases, lands and interests with which any of said interests may now or hereafter be pooled, unitized or
communitized. This Exhibit A shall include all of Grantor’s interest in the leases described or referred to in this Exhibit A, whether beneficially owned or as now or hereafter reflected of
record in the county records, and whether or not all lands covered by said leases are specifically described or referred to. The net revenue interests and/or interests in gross production set forth herein are the interests in production of oil
and/or gas hereby represented and warranted to be owned by Grantor in the properties described, but this Exhibit A shall be deemed to cover any additional interests of Grantor that are in excess of the net revenue interests indicated herein
and such designation shall not be deemed a limitation on the interests covered hereby. Reference is hereby made to each particular instrument described and referred to in this Exhibit A for further description and for all the terms and
conditions thereof and the lands covered thereby. 
 Where references in this Exhibit A state that any described interest is subject
to any referenced agreement, instrument, or outstanding interest, such reference is made only to the extent, if any, that such agreement, instrument or interest is valid and subsisting, and such references shall not create rights in or have any
effect upon any Person not party to this Deed of Trust, to which the Exhibit A is attached. The Subject Leases and Lands are conveyed or mortgaged subject to valid and presently subsisting easements and rights-of-way, either of record or on the ground. All recording references in this Exhibit A are to the official records of the Clerk of the County in which the lands affected by the described
instrument are situated. 
 This Deed of Trust may be executed in multiple counterparts, each of which is an original and all of which are
substantially identical and shall together constitute but one and the same Deed of Trust except that to facilitate recordation, there is attached to each counterpart which is to be recorded only that portion of this
Exhibit A which contains the description of the Lands located in the County where that particular counterpart will be recorded. The Exhibit A to be attached to the financing statement filed in the central filing
jurisdiction of each state shall contain descriptions of all of the Subject Leases and Lands in that state that are affected by this Deed of Trust. 

It is the intention of Grantor herein to convey or mortgage all of its interests in the Subject Leases and the Lands, even though any such oil
and gas property may not be accurately described herein. Any acreage or depth limitation language in this Exhibit A is included for the sole purpose of specifying or limiting the warranties made by Grantor, but it is the intention of Grantor
to subject Grantor’s entire interest in the leases and/or lands described or referred to in this Exhibit A without regard to acreage or depth limitations. 

“Working Interest” or “WI” (expressed as a decimal) shall mean the interest of Grantor in a
particular Subject Lease, well, or unit as the case may be, entitling Grantor to produce oil, gas and other Hydrocarbons produced therefrom and being equivalent to the proportionate part of the cost of exploration, development and production of oil,
gas and other minerals borne by the owners thereof with respect to such Subject Lease or well. 

  
 PREFACE TO EXHIBIT A –
Page 1 

 “Net Revenue Interest” or “NRI” (expressed as a
decimal) means the warranted interest of Grantor representing the proportionate share of the production of oil, gas and other Hydrocarbons produced from the Subject Lease or well as the case may be, to which Grantor is entitled after deduction of
all royalties, overriding royalty interests, production payments and other burdens on or payments out of production, except severance, production, and other similar taxes. 

“Overriding Royalty Interest”, “ORRI” or “ORI” (expressed as a
decimal) means an interest in production which is free of any obligation for the expense of exploration, development and production, bearing only its pro rata share of severance, production and other similar taxes and, in instances where the
document creating the overriding royalty interest so provides, costs associated with compression, dehydration, other treating or processing or transportation of production of oil, gas or other minerals relating to the marketing of such production.

 “Royalty Interest” or “RI” (expressed as a decimal) means an interest in production which
results from an ownership in the mineral fee estate or royalty estate in the relevant lands and which is free of any obligation for the expense of exploration, development and production, bearing only its pro rata share of severance, production and
other similar taxes and, in instances where the document creating the royalty interest so provides, costs associated with compression, dehydration, other treating or processing or transportation of production of oil, gas or other minerals relating
to the marketing of such production. 
 Notwithstanding the percentage of Working Interest, Net Revenue Interest, Overriding Royalty
Interest or Royalty Interest set forth with respect to a particular oil, gas and mineral lease or well, Grantor intends that this Deed of Trust shall convey or mortgage the entirety of Grantor’s interest in the Subject Leases and the Lands.

 Any reference herein to wells or well names, prospects or prospect names, if any, shall be for information purposes and shall not limit
the description of the interests made subject to this Deed of Trust. Each reference to a lease herein shall be deemed a reference to said lease as said lease may have been heretofore amended and/or ratified, whether or not such amendments and
ratifications are referred to herein.

 Section 2.2 Covenants of Mortgagor. Mortgagor,
for Mortgagor and Mortgagor’s successors, covenants and agrees, unless otherwise specifically permitted or allowed in the Credit Agreement, to do the following: 

(a) Cure of Defects. If (i) any legal proceedings are instituted challenging or attacking the validity or priority of this
Mortgage or of any rights or Liens created or evidenced hereby with respect to the Mortgaged Property, or (ii) any adverse claim is made against upon the title to any of the Mortgaged Property other than Permitted Liens, Mortgagor will give
Mortgagee written notice thereof within three (3) business days after Mortgagor has knowledge of such legal proceedings or adverse claim, and, at Mortgagor’s own cost and expense, Mortgagor will diligently endeavor to cure any defect that
may be claimed, and Mortgagor will take all necessary and proper steps for the defense of such legal proceedings, including the employment of counsel reasonably acceptable to Mortgagee, the prosecution or defense of litigation and the release or
discharge of all adverse claims, and Mortgagee (whether or not named as a party to legal proceedings with respect thereto), is hereby authorized and empowered to take such additional steps as in its reasonable judgment and discretion may be
necessary or proper for the defense of any such legal proceedings, including the prosecution or defense of litigation, and the compromise or discharge of any adverse claims made with respect to the Mortgaged Property, and all out-of-pocket expenses
so incurred shall be a demand obligation owing by Mortgagor to Mortgagee in accordance with Section 12.03(a) of the Credit Agreement. 

(b) Maintenance of Subject Leases, Contracts, and Easements. Mortgagor will perform all of Mortgagor’s obligations under and
maintain all Subject Leases, Subject Contracts, and Subject Easements in full force and effect, and Mortgagor will not permit to occur the surrender, abandonment, release, or termination of any Subject Lease, Subject Contracts, or Subject Easements,
so long as the Subject Interests covered thereby or relating thereto are capable of producing Hydrocarbons in paying quantities. 
 (c)
Maintenance of Mortgaged Property. Mortgagor will at all times maintain, preserve, and keep the Mortgaged Property in good repair and condition, and from time to time, make all necessary and proper repairs, replacements, and renewals, and

(d) Mortgage Taxes. At any time any Law shall be enacted imposing or authorizing the imposition of any tax upon this Mortgage, or upon
any Lien created hereby, Mortgagor will immediately pay all such taxes; provided that, in the alternative, Mortgagor may, in the event of the enactment of such a Law, and must, if it is unlawful for Mortgagor to pay such taxes, prepay that portion
of the Obligation which Mortgagee in good faith determines is secured by property covered by such Law within sixty (60) days after demand therefor by Mortgagee. 

(e) Performance of Covenants. Mortgagor will punctually and properly perform all of Mortgagor’s covenants, duties, and liabilities
under the Credit Agreement, this Mortgage and any other security instrument.

MORTGAGE – Page 6 

 (g) Development Work. Mortgagor will do, or cause to be done, such development and other
work as may be reasonably necessary to protect from diminution of production capacity of the Mortgaged Property and each producing well thereon. 

(h) Properties Not Operated by Mortgagor. Anything in this Section 2.2 to the contrary notwithstanding, Mortgagor, with
respect to those Subject Interests which are operated by operators other than Mortgagor, shall not be obligated itself to perform undertakings performable only by such operators and which are beyond the control of Mortgagor. In each such case,
however, Mortgagor will use such commercially reasonable efforts to bring about the performance of any such undertakings required to be performed by such operators.

insurer, flood insurance in an amount sufficient to comply with all applicable Flood Insurance Regulations applicable to the Mortgaged Property, if any. 

ARTICLE 3  
 DEFAULTS
AND REMEDIES 
 Section 3.1 Defaults. The term “default” as used herein shall mean an
Event of Default under the Credit Agreement. 
 Section 3.2 Remedies. If a default shall occur and be continuing,
Mortgagee may, at its option, do any one or more of the following to the extent permitted by applicable Law: 
 (a) Payment or
Performance by Mortgagee. If Mortgagor has failed to keep or perform any covenant whatsoever contained in this Mortgage or any other security instrument, Mortgagee may, but shall not be obligated to any Person to do so, perform or attempt to
perform such covenant, and any payment made or expense incurred in the performance or attempted performance of any such covenant shall be a part of the Obligation, and Mortgagor promises, upon demand, to pay to Mortgagee, at the place where the
Notes are payable, or at such other place as Mortgagee may direct by written notice, all sums so advanced or paid by Mortgagee, with interest at the Highest Lawful Rate, from the date when paid or incurred by Mortgagee until paid by Mortgagor. No
such payment by Mortgagee shall constitute a waiver of any default. In addition to the Liens hereof, Mortgagee shall be subrogated to all rights and Liens securing the payment of any debt, claim, tax, or assessment for the payment of which Mortgagee
may make an advance, or which Mortgagee may pay. 
 (b) Acceleration. Mortgagee may, at its option, declare the aggregate unpaid
principal amount of and interest on the Notes and all other parts of the Obligation (other than liabilities under any Secured Swap Agreements or any Secured Cash Management Agreements) to be, and the same shall thereupon become immediately due and
payable without presentment, demand, protest, notice of acceleration, notice of intent to accelerate, notice of protest or notice of dishonor, or any other notice of any kind, all of which are expressly waived by Mortgagor. 

(c) Power of Sale. Mortgagor hereby confers on Mortgagee the power to sell the Mortgaged Property and the interests of Persons therein
in the manner provided for in the “Oklahoma Power of Sale Mortgage Foreclosure Act” (46 Okla. Stat. §§40 et seq.), as the same may be amended from time to time (the “Act”), or other applicable statutory
authority. Such power of sale shall be exercised by giving Mortgagor a written notice by certified mail of intent to foreclose by power of sale and setting forth, among other things, the nature of the breach(es) or default(s) and the action required
to effect a cure thereof and the time period within 

  
 AMENDED, RESTATED AND CONSOLIDATED
MORTGAGE – Page 7 

 
which such cure may be effected all in compliance with and as may be required by the Act or other applicable statutory authority. If no cure is effected within the applicable statutory time
limits, Mortgagee may accelerate the Obligation without further notice (the aforementioned statutory cure period shall run concurrently with any contractual provision for notice and cure period before acceleration of the Obligation, but in no event
shall the statutory cure period run more than 60 days from the date of the occurrence or event resulting in the default unless a longer period is provided by applicable statute) and may then proceed in the manner and subject to and as required by
the conditions of the Act or other applicable statutory authority to serve upon Mortgagor and other necessary parties and publish a notice of sale and to then sell and convey all or any portion of the Mortgaged Property all in accordance with the
Act or other applicable statutory authority. The sale shall be made as an entirety or in lots, parcels, or divisions, upon such notice, at such time and place, in such manner and under such conditions all as provided for in said Act or other
applicable statutory authority. The proceeds of the sale shall be applied in the manner provided for in the Act or other applicable statutory authority. No action of Mortgagee based upon the provisions contained herein or contained in the Act,
including, without limitation, the giving of the notice of intent to foreclose by power of sale or service of the notice of sale, shall constitute an election of remedies which would preclude from pursuing judicial foreclosure before or at any time
after commencement of the power of sale foreclosure procedure. 
 (d) Suit. Mortgagee may proceed by suit or suits, at Law or in
equity, to enforce the payment and performance of the Obligation in accordance with the terms hereof, of the Notes or the other security instruments, or other documents and/or writings securing and/or evidencing the Obligation, to foreclose the
Liens of this Mortgage as against all or any part of the Mortgaged Property and to have all or any part of the Mortgaged Property sold under the judgment or decree of a court of competent jurisdiction. 

(e) Appointment of Receiver. Mortgagee, as a matter of right and without regard to the sufficiency of the security, and without any
showing of insolvency, fraud or mismanagement on the part of Mortgagor, and without the necessity of filing any judicial or other proceeding other than the proceeding for appointment of a receiver, shall be entitled to the appointment of a receiver
or receivers of the Mortgaged Property, or any part thereof, and of the income, rents, issues and profits thereof. 
 (f) Possession of
Mortgaged Property. Mortgagee may enter upon the Lands included within the Mortgaged Property, take possession of the Mortgaged Property, and remove the Personal Property included within the Mortgaged Property, or any part thereof, with or
without any responsibility or liability on the part of Mortgagee, take possession of any property located on or in the Mortgaged Property which is not a part of the Mortgaged Property and hold or store such property at Mortgagor’s expense. 

(g) Assemble Collateral. Mortgagee may require Mortgagor to assemble the Collateral included within the Mortgaged Property, or any part
thereof, and make it available to Mortgagee at a place to be designated by Mortgagee which is reasonably convenient to Mortgagor and Mortgagee. 

(h) Disposition of Collateral. After notification, if any, as hereafter provided in this Section 3.2(h), Mortgagee may
sell, lease or otherwise dispose of, at the office of Mortgagee, or on the Lands, or elsewhere, as chosen by Mortgagee, all or any part of the personal property Collateral included within the Mortgaged Property, in its then condition, or following
any commercially reasonable preparation or processing, and each sale (as used in this Section 3.2(h), the term “sale” means any such sale, lease, or other disposition made pursuant to this
Section 3.2(h)) may be a unit or in parcels, by public or in private proceedings, and by way of one or more contracts, and, at any sale, it shall not be necessary to exhibit such Collateral, or part thereof, being sold, leased or
otherwise disposed of. The sale of any part of the Collateral shall not exhaust Mortgagee’s power of sale, but sales may be made from time to time until the Obligation is paid and performed in full. Reasonable notification of the time and place
of any public sale pursuant to this Section 3.2(h), or reasonable notification of the time after which any private sale is to be made pursuant to this Section 3.2(h), shall be sent to Mortgagor and to any other Person
entitled under the applicable Code to notice. To the extent any sale is conducted pursuant to the Code, it is agreed that notice sent or given not less than ten (10) calendar days prior to the taking of the action to which the notice relates,
is reasonable notification and notice for such purposes of this Section 3.2(h). 

  
 AMENDED, RESTATED AND CONSOLIDATED
MORTGAGE – Page 8 

 (i) Surrender of Insurance Policies. Mortgagee may surrender the insurance policies
maintained pursuant to the Credit Agreement, or any part thereof, and receive and apply the unearned premiums as a credit on the Obligation, and, in connection therewith, Mortgagor hereby appoints Mortgagee as the agent and attorney-in-fact for
Mortgagor to collect such premiums (which appointment is coupled with an interest and irrevocable while this Mortgage is in effect). 

Section 3.3 Purchase of Mortgaged Property by Mortgagee. If Mortgagee or any Secured Party is the purchaser of the
Mortgaged Property, or any part thereof (and it is specifically agreed that Mortgagee or any Secured Party may be the purchaser of the Mortgaged Property, or any part thereof, if permitted by applicable Law), at any sale thereof, whether such sale
be under the power of sale hereinabove vested in Mortgagee, or upon any other foreclosure of the Liens hereof, or otherwise, Mortgagee or the relevant Secured Party, as the case may be, shall, upon any such purchase, acquire good title to the
Mortgaged Property so purchased, free of the Liens of these presents. 
 Section 3.4 Operation of Properties by
Mortgagee. Should any part of the Mortgaged Property come into the possession of Mortgagee, whether before or after default, Mortgagee may use or operate (to the extent allowed under applicable operating arrangements) the Mortgaged Property
for the purpose of preserving it or its value, pursuant to the order of a court of appropriate jurisdiction, or in accordance with any other rights held by Mortgagee in respect to the Mortgaged Property. Mortgagor covenants promptly to reimburse and
pay to Mortgagee, at the place where Notes are payable, or at such other place as may be designated by Mortgagee in writing, the amount of all expenses (including the cost of any insurance, taxes, reasonable attorneys’ fees and other charges)
incurred by Mortgagee in connection with its custody, preservation, use or operation of the Mortgaged Property, together with interest thereon from the date incurred by Mortgagee at the Highest Lawful Rate, and all such expenses, cost, taxes,
interest and other charges shall be a part of the Obligation. It is agreed, however, that the risk of loss or damage to the Mortgaged Property is on Mortgagor, and Mortgagee shall have no liability whatever for decline or diminution in value of the
Mortgaged Property, nor for failure to obtain or maintain insurance, nor for failure to determine whether any insurance ever in force is adequate as to amount or as to the risks insured, except to the extent such loss or damage results from the
gross negligence or willful misconduct of Mortgagee, as determined by a court of competent jurisdiction by a final and non-appealable judgment. 

Section 3.5 Possession of Property After Foreclosure. In case the Liens hereof shall be foreclosed by power of sale, or by
other judicial or non-judicial action, the purchaser at any such sale shall receive, as an incident to his ownership, immediate possession of the Mortgaged Property, or any part thereof so conveyed, and, subsequent to foreclosure, Mortgagor and
Mortgagor’s successors shall be considered as tenants at sufferance of the purchaser at foreclosure sale, and anyone occupying the property after demand made for possession thereof shall be guilty of forcible detainer and shall be subject to
eviction and removal, forcible, or otherwise, with or without process of Law, and all damages by reason thereof are hereby expressly waived. 

Section 3.6 Application of Proceeds. The proceeds from any sale, lease or other disposition made pursuant to this
Article 3, any proceeds of Hydrocarbons collected by Mortgagee pursuant to Article 4, and sums received pursuant to Section 6.5 shall be applied by Mortgagee first to the payment of any and all expenses incurred by
Mortgagee in foreclosing upon the Property and carrying out such sale (including any attorneys’ fees); and second to the payment or prepayment of the Obligation, whether or not matured, all in accordance with the Credit Agreement;
provided, however, that notwithstanding the foregoing or anything to the contrary herein or in any other Loan Document, no such proceeds shall be applied to any Excluded Swap Obligations.  

Section 3.7 Abandonment of Sale. In the event a foreclosure hereunder should be commenced in accordance with
Section 3.2(c), Mortgagee may at any time before the sale abandon the sale and exercise any other remedies available to Mortgagee. 

Section 3.8 Waiver of Appraisement and Redemption. To the full extent Mortgagor may lawfully do so, Mortgagor agrees
that Mortgagor will not at any time insist upon, plead, claim or take the benefit or advantage of any appraisement, valuation, stay, extension or redemption Laws, now or hereafter in force, in order

  
 AMENDED, RESTATED AND CONSOLIDATED
MORTGAGE – Page 9 

 
to prevent or hinder the enforcement of this Mortgage or the absolute sale of the Mortgaged Property or any part thereof, or the possession thereof by any purchaser at any such sale, and
Mortgagor, insofar as Mortgagor now or hereafter may lawfully do so, hereby waives the benefit of all such Laws; provided, however, that the appraisement of any of the Mortgaged Property is hereby expressly waived or not waived at the option of
Mortgagee, such option to be exercised prior to or at the time judgment is rendered in any foreclosure of this Mortgage. Mortgagor also expressly waives, to the extent Mortgagor may lawfully do so, all rights to have the Mortgaged Property marshaled
upon any foreclosure of this Mortgage. 
 ARTICLE 4  

ASSIGNMENT OF PRODUCTION 

Section 4.1 Assignment and Additional Security. In addition to the conveyance to Mortgagee herein made and to
additionally secure the Obligation, Mortgagor has, effective as of 7:00 o’clock a.m., local time, on the first day of the month in which this Mortgage is executed, at the site of each of the Subject Leases, ASSIGNED, TRANSFERRED AND CONVEYED,
and does hereby ASSIGN, TRANSFER AND CONVEY, unto Mortgagee all of the following: 
 (a) All Hydrocarbons, and the proceeds therefrom
and products obtained or processed therefrom (such proceeds and products being herein called “Proceeds”), produced and to be produced from the Mortgaged Property, and all rights of Mortgagor to Liens securing payment of
Proceeds, including those Liens provided for in the Oil and Gas Owners’ Lien Act of 2010 (52 Okla. Stat. 549, 1-549.12). Mortgagor hereby authorizes and empowers Mortgagee, during the existence of a default, to demand, collect and receive such
Hydrocarbons and Proceeds, to endorse and cash any checks and drafts payable to Mortgagor or Mortgagee for the account of Mortgagor received from or in connection with such Hydrocarbons and Proceeds, to execute any release, receipt, division order,
transfer order, and relinquishment or other instrument that may be required or necessary to collect and receive such Hydrocarbons and Proceeds, and to exercise any rights as the holder of Liens securing payment of Proceeds. Mortgagor hereby
authorizes and directs all pipeline companies, gathering companies, and others purchasing such Hydrocarbons or having in their possession any such Hydrocarbons or Proceeds, to pay and deliver to Mortgagee all such Hydrocarbons and Proceeds upon the
written request of Mortgagee during the existence of a default; provided that Mortgagor does hereby specifically agree that all such pipeline companies, gathering companies and others purchasing or having in their possession such Hydrocarbons
and Proceeds shall be entitled to rely, and shall be fully protected in relying upon, notice by Mortgagee that a default exists. Mortgagor agrees that all division orders, transfer orders, receipts and other instruments which Mortgagee may from time
to time execute and deliver for the purpose of collecting or receipting for Hydrocarbons or Proceeds may be relied upon in all respects and that the same shall be binding upon Mortgagor and Mortgagor’s successors. Mortgagor agrees to execute
and deliver all necessary, convenient and appropriate instruments, including transfer and division orders, which may be required by Mortgagee in connection with the receipt by Mortgagee of such Hydrocarbons or Proceeds and to indemnify and keep and
hold Mortgagee free and harmless from all parties whomsoever having or claiming an adverse interest in such Hydrocarbons and Proceeds and in this respect agrees to pay all expenses, costs, charges and attorneys’ fees that may be incurred by
Mortgagee as to any of such matters. 
 (b) All proceeds hereafter payable to or to become payable to Mortgagor or to which Mortgagor is
entitled under all gas sales or exchange contracts, all oil, distillate, or condensate sales or exchange contracts, all gas transportation contracts, and all gas processing contracts now or hereafter to become a part of the Mortgaged Property. 

(c) All amounts, sums, revenues, income and proceeds which become payable to Mortgagor from any of the Mortgaged Property (including any
after-acquired properties) or under any contract, present or future, relating to, any gas pipeline system and processing plant or unit now or hereafter constituting a part of the Mortgaged Property. 

(d) All lease bonus, delay rentals, royalties and shut-in gas royalties which become payable to Mortgagor from any of the Mortgaged Property.

  
 AMENDED, RESTATED AND CONSOLIDATED
MORTGAGE – Page 10 

 Section 4.2 Transfer Orders. Mortgagor agrees to execute such transfer
orders, payment orders, division orders and other instruments as may be needed by Mortgagee or requested by it incident to its having all assigned payments made direct to it. Mortgagor authorizes and directs all such pipeline companies, purchasers,
transporters and other parties owing moneys to Mortgagor under contracts herein assigned, to pay such amounts direct to Mortgagee upon the written request by Mortgagee during the existence of a default as follows: 

Compass Bank, as Administrative Agent 

2200 Post Oak Boulevard, 17th Floor 

Houston, Texas 77056 
 and such
authorization shall continue until this Mortgage is released. During the existence of a default, Mortgagee is authorized to collect, receive, and give receipt for all such amounts, and no party making payment shall have any responsibility to see to
the application of any funds paid to Mortgagee but shall be fully protected in making such payment to Mortgagee under the assignments herein contained. Should Mortgagee bring suit against any third party for collection of any amounts or sums
included within this assignment (and Mortgagee shall have the right to bring any such suit), it may sue either in its own name or in the name of Mortgagor. 

Section 4.3 Payment of Proceeds. In the event that, for its convenience, Mortgagee should elect with respect to particular
properties or contracts not to exercise immediately its right to receive Hydrocarbons or proceeds, then the purchasers or other Persons obligated to make such payment shall continue to make payment to Mortgagor until such time as written demand has
been made upon them by Mortgagee that payment be made directly to Mortgagee. Such failure to notify shall not in any way waive the right of Mortgagee to receive any payments not theretofore paid out to Mortgagor before the giving of written notice.
In this regard, in the event payments are made directly to Mortgagee, and then, at the request of Mortgagee payments are, for a period of time, paid to Mortgagor, Mortgagee shall nevertheless have the right, effective upon written notice, to require
that future payments be again made to Mortgagee. 
 Section 4.4 Proceeds Held in Trust by Mortgagor. If under any
existing gas sales or exchange agreements or products sales or exchange contracts, other than division orders or transfer orders, or under any gas transportation contract, any proceeds are required to be paid by the purchaser or transporter direct
to Mortgagor so that under such existing agreements payment cannot be made to Mortgagee in the absence of foreclosure, then Mortgagor’s interest in all proceeds under such sales agreement and in all other proceeds which for any reason
may be paid to Mortgagor shall, when received by Mortgagor during the existence of a default, constitute trust funds in his hands and shall be immediately paid over to Mortgagee, if Mortgagee has requested that such payments be delivered to it under
this assignment. 
 Section 4.5 Limitation of Liability of Mortgagee. Mortgagee is hereby absolved from all
liability for failure to enforce collection of the proceeds and amounts assigned under Section 4.1 above and from all other responsibility in connection therewith, except the responsibility to account to the Persons legally entitled
thereto (by application upon the Obligation or otherwise) for funds actually received. Mortgagor agrees to indemnify and hold harmless Mortgagee against any and all liabilities, actions, claims, judgments, costs, charges, and attorneys’ fees by
reason of the assertion that Mortgagee has received, either before or after payment and performance in full of the Obligation, funds from the production of Hydrocarbons claimed by third Persons, and Mortgagee shall have the right to compromise and
adjust any such claims, actions, and judgments, and in addition to the rights to be indemnified as herein provided, all amounts paid by Mortgagee in compromise, satisfaction, or discharge of any such claim, action or judgment, and all court costs,
attorneys’ fees, and other expenses of every character incurred by Mortgagee, pursuant to the provisions of this Section, shall be demand obligations owing by Mortgagor and shall bear interest at the Highest Lawful Rate from date of expenditure
until paid and shall be secured by the Liens created and granted by this Mortgage. 
 Section 4.6 Duty to Pay
Obligation. Nothing contained herein shall limit Mortgagor’s absolute duty to make payment when due of the Obligation when the Proceeds received by Mortgagee pursuant to Section 4.1 hereof are insufficient to pay the same,
and receipt of Proceeds under said Section 4.1 shall be in addition to all other security now or hereafter existing to secure payment of the Obligation.

 Section 4.7 Power of Attorney to Mortgagee. Mortgagor does hereby
designate Mortgagee as the agent of Mortgagor to act in the name, place and stead of Mortgagor for the purpose of taking any and all actions deemed by Mortgagee necessary for the realization by Mortgagee of the benefits of the assignment of Proceeds
provided herein, recognizing such agency in favor of Mortgagee to be coupled with the interests of Mortgagor under this Mortgage and, thus, irrevocable as long as this Mortgage is in force and effect. All Persons dealing with Mortgagee, or any
officer thereof, or any substitute, shall be fully protected in treating the powers and authorities conferred by this Section as continuing in full force and effect until advised by Mortgagee that the entire Obligation is fully and finally paid.

 Section 5.2 Reproduction of
Mortgage as Financing Statement. A photographic or other reproduction of this Mortgage or of any financing statement relating to this Mortgage shall be sufficient as a financing statement for any of the purposes referred to in Section
5.1. 
 Section 5.3 Notice to Account Debtors. In addition to the rights granted in Article 4
hereof, Mortgagee may at any time during the existence of a default notify the account debtors or obligors of any accounts, chattel paper, negotiable instruments or other evidences of indebtedness included in the Collateral to pay Mortgagee
directly.  
 Section 5.4 Filing of Financing Statement. Mortgagee shall have the right, without the
consent or joinder of Mortgagor, to execute and file with any Governmental Authority such financing statements, financing statement amendments and continuation statements as may, in the sole discretion of Mortgagee, be necessary or advisable to
maintain, perfect or otherwise evidence the Lien of Mortgagee in and to any of the Mortgaged Property. Mortgagor, as debtor, hereby expressly authorizes Mortgagee, as secured party, to file any such financing statement without the signature of
Mortgagor to the extent permitted by applicable Law.

MORTGAGE – Page 12

the conditions, covenants and terms of this Mortgage and other security instruments, and the employment or enforcement of any rights hereunder, or otherwise, shall not prevent the concurrent or subsequent employment or enforcement of any other
rights. 
 Section 6.3 Waivers. Any and all covenants in this Mortgage may from time to time, by instrument
in writing signed by Mortgagee (with the requisite approval, if any, of all Lenders or the Majority Lenders pursuant to the Credit Agreement) and delivered to Mortgagor, be waived to such extent and in such manner as Mortgagee and the applicable
Lenders may desire, but no such waiver shall ever affect or impair Mortgagee’s rights and Liens hereunder, except to the extent specifically stated in such written instruments. 

Section 6.4 Sale of Mortgaged Property. In the event Mortgagor or any of Mortgagor’s successors conveys any
interest in the Mortgaged Property, or in any part thereof, to any other party, Mortgagee may, without notice to Mortgagor or Mortgagor’s successors, deal with any owner of any part of the Mortgaged Property with reference to this Mortgage and
the Obligation, either by way of forbearance on the part of Mortgagee, or extension of time of payment of the Obligation, or release of all or any part of the Mortgaged Property, or any other property securing payment and performance of the
Obligation, without in any way modifying or affecting Mortgagee’s rights and Liens hereunder or the liability of Mortgagor or any other party liable for payment and performance of the Obligation, in whole or in part;
provided that no action taken or omitted to be taken by Mortgagee under this Section 6.4 shall be deemed a waiver of any default occurring by reason of any such conveyance. 

Section 6.5 Condemnation Sale. Mortgagee shall be entitled to receive any and all sums which may be awarded or
become payable to Mortgagor for the condemnation of the Mortgaged Property, or any part thereof, for public or quasi-public use, or by virtue of private sale in lieu thereof, and any sums which may be awarded or become payable to Mortgagor
for damages caused by public works or construction on or near the Mortgaged Property. All such sums are hereby assigned to Mortgagee, and Mortgagor shall, upon request of Mortgagee, make, execute, acknowledge and deliver any and all additional
assignments and documents as may be necessary from time to time to enable Mortgagee to collect and receipt for any such sums. Mortgagee shall not be, under any circumstances, liable or responsible for failure to collect, or exercise diligence in the

the proceeds of the Notes or of any further loans or advances, to the extent the same are utilized to renew or extend any indebtedness or take up any outstanding Liens against the Mortgaged Property, or any portion thereof, have been advanced by the
Secured Parties at Mortgagor’s request and upon Mortgagor’s representation that such amounts are due and payable. The Secured Parties shall be subrogated to any and all rights and Liens owned or claimed by any owner or holder of such
outstanding rights and Liens, however remote, regardless of whether such rights and Liens are acquired by assignment or are released by the holder thereof upon payment. 

Section 6.7 Waiver of Marshaling. Mortgagor hereby waives all rights of marshaling in the event of any foreclosure
of the Liens hereby created.

Mortgage amends, restates, supplements and consolidates (but does not extinguish or novate) the Existing Mortgages. The execution, delivery and effectiveness of this Mortgage shall not discharge or release any Lien or priority of any Existing
Mortgage, or any other security instrument securing the Obligation. This Mortgage continues, renews and extends all liens, rights, powers, privileges, superior titles, estates and security interests existing by virtue of the Existing Mortgages

hereto.

provisions of this Mortgage and the terms and provisions of the Credit Agreement, the terms and provisions of the Credit Agreement shall control; provided, however, a more expansive or explanatory term or

 PREFACE TO EXHIBIT A TO 

AMENDED, RESTATED AND CONSOLIDATED MORTGAGE OF OIL AND GAS PROPERTY, ASSIGNMENT, 

SECURITY AGREEMENT AND FINANCING STATEMENT, 

DATED AS OF MAY 5, 2017 

FROM PRIMEENERGY CORPORATION AND PRIMEENERGY MANAGEMENT CORPORATION 

TO COMPASS BANK, ADMINISTRATIVE AGENT 

This Exhibit A contains a description of those Subject Leases and Lands referred to in the foregoing Mortgage. The Subject Leases and
Lands consist of producing and non-producing oil and gas leases, oil, gas and mineral interests, oil and gas royalty interests, and oil and gas overriding royalty interests affecting lands situated in the State of Oklahoma in each of the counties
listed on the cover page of this Mortgage, together with all of Mortgagor’s interest in all leases, lands and interests with which any of said interests may now or hereafter be pooled, unitized or communitized. This Exhibit A shall
include all of Mortgagor’s interest in the leases described or referred to in this Exhibit A, whether beneficially owned or as now or hereafter reflected of record in the county records, and whether or not all lands covered by said
leases are specifically described or referred to. The net revenue interests and/or interests in gross production set forth herein are the interests in production of oil and/or gas hereby represented and warranted to be owned by Mortgagor in the
properties described, but this Exhibit A shall be deemed to cover any additional interests of Mortgagor that are in excess of the net revenue interests indicated herein and such designation shall not be deemed a limitation on the interests
covered hereby. Reference is hereby made to each particular instrument described and referred to in this Exhibit A for further description and for all the terms and conditions thereof and the lands covered thereby. 

Where references in this Exhibit A state that any described interest is subject to any referenced agreement, instrument, or outstanding
interest, such reference is made only to the extent, if any, that such agreement, instrument or interest is valid and subsisting, and such references shall not create rights in or have any effect upon any Person not party to this Mortgage, to which
the Exhibit A is attached. The Subject Leases and Lands are conveyed or mortgaged subject to valid and presently subsisting easements and rights-of-way, either of record or on the ground. All recording references in this Exhibit A are
to the official records of the Clerk of the County in which the lands affected by the described instrument are situated. 
 This Mortgage
may be executed in multiple counterparts, each of which is an original and all of which are substantially identical and shall together constitute but one and the same Mortgage except that to facilitate recordation, there is attached to each
counterpart which is to be recorded only that portion of this Exhibit A which contains the description of the Lands located in the County where that particular counterpart will be recorded. The Exhibit A to be attached to the
financing statement filed in the central filing jurisdiction of each state shall contain descriptions of all of the Subject Leases and Lands in that state that are affected by this Mortgage. 

It is the intention of Mortgagor herein to convey or mortgage all of its interests in the Subject Leases and the Lands, even though any such
oil and gas property may not be accurately described herein. Any acreage or depth limitation language in this Exhibit A is included for the sole purpose of specifying or limiting the warranties made by Mortgagor, but it is the intention of
Mortgagor to subject Mortgagor’s entire interest in the leases and/or lands described or referred to in this Exhibit A without regard to acreage or depth limitations. 

“Working Interest” or “WI” (expressed as a decimal) shall mean the interest of
Mortgagor in a particular Subject Lease, well, or unit as the case may be, entitling Mortgagor to produce oil, gas and other Hydrocarbons produced therefrom and being equivalent to the proportionate part of the cost of exploration, development and
production of oil, gas and other minerals borne by the owners thereof with respect to such Subject Lease or well. 

“Net Revenue Interest” or “NRI” (expressed as a decimal) means the warranted
interest of Mortgagor representing the proportionate share of the production of oil, gas and other Hydrocarbons produced from the Subject Lease or well as the case may be, to which Mortgagor is entitled after deduction of all royalties, overriding
royalty interests, production payments and other burdens on or payments out of production, except severance, production, and other similar taxes. 

  
 PREFACE TO EXHIBIT A –
Page 1 

 “Overriding Royalty Interest”,
“ORRI” or “ORI” (expressed as a decimal) means an interest in production which is free of any obligation for the expense of exploration, development and production, bearing only its pro rata share of
severance, production and other similar taxes and, in instances where the document creating the overriding royalty interest so provides, costs associated with compression, dehydration, other treating or processing or transportation of production of
oil, gas or other minerals relating to the marketing of such production.  
 “Royalty
Interest” or “RI” (expressed as a decimal) means an interest in production which results from an ownership in the mineral fee estate or royalty estate in the relevant lands and which is free of any obligation for
the expense of exploration, development and production, bearing only its pro rata share of severance, production and other similar taxes and, in instances where the document creating the royalty interest so provides, costs associated with
compression, dehydration, other treating or processing or transportation of production of oil, gas or other minerals relating to the marketing of such production. 

Notwithstanding the percentage of Working Interest, Net Revenue Interest, Overriding Royalty Interest or Royalty Interest set forth with
respect to a particular oil, gas and mineral lease or well, Mortgagor intends that this Mortgage shall convey or mortgage the entirety of Mortgagor’s interest in the Subject Leases and the Lands. 

Any reference herein to wells or well names, prospects or prospect names, if any, shall be for information purposes and shall not limit the
description of the interests made subject to this Mortgage. Each reference to a lease herein shall be deemed a reference to said lease as said lease may have been heretofore amended and/or ratified, whether or not such amendments and ratifications
are referred to herein.
