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.

(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.

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

▇▇▇▇ ▇▇▇▇ ▇▇▇ ▇▇▇▇▇▇▇▇▇, ▇▇^▇▇ ▇▇▇▇▇

▇▇▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇

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 ▇▇▇ 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.

AMENDED, RESTATED AND CONSOLIDATED MORTGAGE – Page 11

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.

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 ▇▇▇▇▇ 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.
