This Asset Purchase and Sale Agreement (this “Agreement”) is made and entered into this 8th day of April, 2014, by and between Chaparral Energy, L.L.C., an Oklahoma limited liability company, (the “Seller”), having as its address 701 Cedar Lake Boulevard, Oklahoma City, Oklahoma 73114, and RKI Exploration & Production, LLC, a Delaware limited liability company, having as its address 210 Park Avenue, Suite 900, Oklahoma City, Oklahoma 73102 (“Purchaser”). Seller and Purchaser are sometimes collectively referred to in this Agreement as the “Parties” or individually as a “Party”.

WHEREAS, Seller is the owner of the Assets (as defined below); and

WHEREAS, Seller is willing to sell and deliver to Purchaser, and Purchaser is willing to purchase and receive from Seller, the Assets upon the terms and conditions set forth in this Agreement.

NOW, THEREFORE, for and in consideration of the mutual promises of the Parties contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

1.1    Agreement to Sell and Purchase. Subject to the terms and conditions of this Agreement, Purchaser agrees to purchase and receive, and Seller agrees to sell, assign, transfer, convey, and deliver, the Assets, as of the Effective Date (as defined below).

1.2    Assets. The term “Assets” as used herein shall mean, subject to the provisions of Section 1.6, all of Seller’s right, title and interest in and to the following:

(collectively “Hydrocarbons”) (i) produced from or allocable to the interests of Seller in the Properties and existing in pipelines, storage tanks, or other processing or storage facilities upstream of the delivery points to the relevant purchasers on the Effective Date, and (ii) produced from or allocable to such interests of Seller on and after the Effective Date;

facilities, supplies and other property, excluding, however, the Wells, being collectively called the “Personal Property”).

1.3    Effective Date. Ownership of the Assets shall be transferred from Seller to Purchaser at the Closing (as defined below), but shall be effective as provided in Section 2.4 below as of 7:00 a.m. (local time where the Assets are located) on March 1, 2014 (the “Effective Date”). Except as may be otherwise specifically provided herein, Seller shall be entitled to any amounts realized from and accruing to the Assets (including contract rights, gas contract settlements, take-or-pay claims, and other claims and causes of action) for all periods prior to the Effective Date and, except as expressly assumed by Purchaser hereunder, shall be liable for the payment of all expenditures relating to the Assets and attributable to all periods prior to the Effective Date. Except as may be otherwise specifically provided herein, Purchaser shall be entitled to any amounts realized from and accruing to the Assets for all periods on and after the Effective Date, and shall be liable for the payment of all expenses relating to the Assets and attributable to all periods on and after the Effective Date.

1.4    Gauging and Strapping. Seller has caused the oil storage facilities on or utilized in connection with the Properties to be gauged or strapped as of the Effective Date for those Properties for which Seller serves as operator. Seller also has caused the gas production meter charts (or if such do not exist, the sales meter charts) on the pipelines transporting gas production from the Assets to be read as of the Effective Date for those Properties for which Seller serves as operator. Prior to the Closing, Purchaser, upon request, shall be provided with access to the records of the gauging, strapping or chart reading for the purpose of verifying such records. For those Properties not operated by a Seller, applicable state regulatory agency production reports or records shall be used to determine the amount of oil in storage or gas existing in the pipeline as of the Effective Date. If such state records or reports are not available or sufficient, Seller’s reasonable estimate based on historical data shall be used.

1.5    Records. Seller shall deliver to Purchaser, within thirty (30) days after the Closing or such later time as Purchaser may request, but in no event later than three (3) months after the Closing, all Records. Seller shall have the right to make and retain such copies of the Records as Seller may

desire prior to the delivery of the Records to Purchaser. Purchaser, for a period of seven (7) years after the Closing, shall further make available to Seller (at the location of such Records in Purchaser’s organization) access to the Records during normal business hours, upon written request of Seller, and Seller shall have the right to copy at its own expense and retain such copies of the Records. If, however, Purchaser elects to destroy any of the Records, prior to the expiration of such seven (7) year period, Purchaser shall give to Seller written notice of such intent at least thirty (30) days prior to such destruction, and Seller shall have the option, at its expense, of having such Records delivered to them. This obligation shall be an obligation running with the land, and Purchaser shall include the obligations set forth in this Section 1.5 as an obligation of any subsequent purchaser of any of the Properties in the applicable purchase and sale agreement with, and/or assignment to, such subsequent purchaser. Without limiting the application of any other provision or remedy available to Purchaser pursuant to this Agreement, Purchaser shall have no recourse or claim against Seller and shall hold Seller harmless from and against any claim of whatsoever nature as the result of the Records furnished to Purchaser by Seller.

1.6    Excluded Assets. Seller excepts, reserves, and retains to itself the following rights, properties and assets: (i) all corporate, financial, legal, and tax records of Seller, including, without limitation, all documents protected by the attorney-client privilege (other than title opinions); (ii) all deposits, cash, checks, cash equivalents and funds attributable to the Assets for the period prior to the Effective Date; (iii) all rights, interests, and claims that any Seller may have under any policy of insurance or indemnity, surety bond, or any insurance or condemnation proceeds or recoveries from third persons relating to property damage or Casualty Loss affecting the Assets occurring prior to the Effective Date; (iv) all claims, whether in contract, in tort, or arising by operation of law, and whether asserted or unasserted as of the Closing Date, that any Seller may have against any person arising out of acts, omissions, or events, or injury to or death of persons or loss or destruction of or damage to property, relating in any way to, the Assets that occurred prior to the Effective Date; provided, however, that no such claim may be settled, compromised, or otherwise resolved in a manner that results in an obligation borne by Purchaser or the Assets on and after the Effective Date without the prior written consent of Purchaser, which shall not be unreasonably withheld or delayed; (v) all exchange traded futures contracts and over-the-counter derivative contracts of Seller as to which Seller has an open position as of the Effective Date; (vi) any and all rights to use Seller’s names, marks, trade dress or insignia, or to use the name of Seller, and all of Seller’s intellectual property, including, without limitation, proprietary or licensed computer software; patents; trade secrets; copyrights; geological and geophysical information and data (including, without limitation, conventional 2-D and 3-D seismic data) licensed from third persons, and Seller’s proprietary interpretations thereof; economic analyses; and pricing forecasts; (vii) all amounts due or payable to Seller as adjustments to insurance premiums related to the Assets for periods prior to the Effective Date; (viii) all claims of Seller for any tax refunds and loss carry-forwards and carry-backs with respect to any taxes relating to the Assets for periods prior to the Effective Date; (iv) all audit rights and all amounts due or payable to Seller as refunds, adjustments, or settlements of disputes arising under the Properties or the Existing Contracts for periods prior to the Effective Date; (x) all inventories of pipe, equipment and other Personal Property; (xi) all rights, titles, and interests of Seller in and to all tools, equipment and similar personal property temporarily located on the Hydrocarbon Interests or the Properties; (xii) all cars, trucks, trailers, backhoes, graders and other similar rolling stock and equipment; and (xiii) all other interests, rights, property, and assets of Seller not located on or used in connection with the Assets or otherwise specifically included in the definition of the Assets.

2.1    Purchase and Sale. At the Closing, Seller shall sell, assign, transfer, and convey to Purchaser, and Purchaser shall purchase and pay for, the Assets, and Purchaser shall also assume the Assumed Obligations as set forth in Section 13.3.1.

2.2    Purchase Price. The purchase price to be paid by Purchaser to Seller with respect to the Assets shall be ONE HUNDRED TWENTY FIVE MILLION Dollars U.S. ($125,000,000.00) (the “Purchase Price”), subject to the adjustments provided in Section 2.4. The amount of the Purchase Price has been agreed to taking into account, among other factors, the perceived value of the Assets and Purchaser’s assumption of the Assumed Obligations as set forth in Section 13.3.1.

2.3    Performance Deposit. As evidence of good faith intentions to consummate the transactions contemplated hereby, contemporaneously with the execution of this Agreement, Purchaser has tendered to Seller a cash performance deposit in the amount of ten percent (10%) of the Purchase Price, said amount being TWELVE MILLION FIVE HUNDRED THOUSAND Dollars U.S. ($_12,500,000.00) (the “Performance Deposit”). If this Agreement is terminated by Seller pursuant to Section 14.1.2, Seller may elect to retain the Performance Deposit as liquidated damages representing Seller’s sole remedy for Purchaser’s failure to consummate the transaction contemplated herein (without waiving any indemnification obligation of Purchaser). The Parties agree that the Performance Deposit is a reasonable sum considering all the circumstances existing on the date of this Agreement, including the relationship of the sum to the range of harm to Seller that reasonably could be anticipated and the anticipation that proof of actual damages would be costly or inconvenient. If this Agreement is terminated for any reason other than Section 14.1.2, the Performance Deposit shall be returned to Purchaser as Purchaser’s sole remedy. In the event the transactions contemplated herein close, the Performance Deposit shall be retained by Seller and credited against the Purchase Price payable by Purchaser hereunder.

2.4    Determination of Adjusted Purchase Price. The net purchase price for the Assets (the “Adjusted Purchase Price”) shall be determined as follows:

expenditures); operating costs (including direct costs chargeable under applicable operating agreements or otherwise and consistent with the standards established by COPAS) and Seller charges and overhead reimbursements authorized pursuant to Section 8.3; and, all costs incurred by Seller associated with working over, drilling or completing of Wells which may be properly categorized as PDP on the Closing Date, but which were categorized in the virtual data room hosted by RBC Capital Markets, LLC as PDNPs, PUDs, Horz or Probables, as more particularly described on Schedule 2.4.3;

2.5    Payment of Adjusted Purchase Price. At the Closing, Purchaser shall cause to be delivered by wire transfer to Seller in accordance with wire transfer instructions provided by Seller an amount in immediately available U.S. funds equal to the Purchase Price, plus or minus the adjustments provided for in Section 2.4 (to the extent then known) calculated as provided in Section 12.3 (the “Preliminary Amount”). The Preliminary Amount paid at the Closing shall be subject to later adjustment pursuant to Section 13.1.

2.6    Tax Purchase Price Allocations. Seller and Purchaser recognize that reporting requirements, as imposed by Section 1060 of the Internal Revenue Code of 1986, as amended (the “IRC” or “Code”), and the regulations thereunder, may apply to the transaction contemplated by this Agreement. Except as may otherwise be required by the IRC and regulations thereunder or other Applicable Laws, Seller and Purchaser agree (i) that for tax reporting purposes, the Purchase Price shall be allocated among the Assets as set forth in Schedule 2.6, and such allocation shall be used in preparing Internal Revenue Service Form 8594 (“Form 8594”) pursuant to the regulations under Section 1060, and (ii) not to assert, in connection with any tax return, tax audit, or similar proceeding, any allocation of the Purchase Price that differs from that set forth in Schedule 2.6 to this Agreement. Upon any adjustment of the Purchase Price following the execution of this Agreement, Seller and Purchaser shall adjust the allocations reflected in Schedule 2.6 accordingly and report such adjustments in conformity with Section 1060 and the regulations thereunder.

3.1    Access to Records and Assets. Upon execution of this Agreement and until the Closing, and thereafter to the extent Seller retains physical possession of any of the Assets and/or Records, Seller shall make the Records available to Purchaser at its offices located at the address set forth in the introductory paragraph of this Agreement, during normal business hours, for examination and copying by Purchaser and, with respect to the Properties operated by Seller, shall grant Purchaser access to such Properties for inspection. Seller shall not be obligated to perform any title work or provide abstracts other than those presently in Seller’s possession, nor will any existing title opinions be brought current by Seller. Seller will use reasonable commercial efforts to furnish to Purchaser all other information with respect to the Assets that Purchaser may from time to time reasonably request, except to the extent that Seller determines in good faith that it is prohibited by agreement with a third party from disclosing the information covered thereby. Purchaser agrees to conduct its due diligence in a professional and orderly manner and at its own cost and expense without disruption of Seller’s normal and usual operations. Purchaser shall indemnify and hold harmless Seller and its partners, shareholders, members, officers, directors, trustees, employees, agents (including, without limitation, RBC Capital Markets, LLC) and representatives (collectively the “Seller Group”) from any and all claims, demands, damages, losses, liabilities, costs and expenses, including court costs and reasonable attorney’s fees (collectively “Costs”), resulting from Purchaser’s acts or omissions in connection with its access to the Assets, regardless of whether such Costs are attributable, in whole or in part, to the negligence, sole or concurrent, of the Seller Group.

3.2    Definitions. For purposes of this Agreement, the following expressions and terms will have the meanings set forth hereinafter:

county records; and (e) irregularities cured by possession under applicable statutes of limitation and statutes relating to acquisitive (or liberative) prescription; and

3.3    Notice of Title Defect. During the period of time between the execution of this Agreement and May 8, 2014 (the “Due Diligence Period”), Purchaser may review title to the Properties and may notify Seller in writing (the “Title Defect Notice”) of any Title Defect; provided, however, Purchaser shall notify Seller of any Title Defect it discovers as soon as reasonably practicable after its discovery. Any notice provided hereunder shall include appropriate evidence to substantiate the Purchaser’s position, including identification of the Title Defect Property, a description of the Title Defect(s) asserted by Purchaser with respect to such Title Defect Property, the basis for the Title Defect(s), the Allocated Value of the Title Defect Property, the portion of the Title Defect Property affected by the Title Defect, the Title Defect Amount asserted by Purchaser with respect to such Title Defect, and the computations and information upon which Purchaser’s assertion is based. Purchaser will be deemed to have conclusively waived any Title Defect discovered by Purchaser during the Due Diligence Period about which it fails to notify Seller in writing in the manner described above prior to the expiration thereof; provided, however, that Purchaser shall not be

deemed to have waived any such Title Defect for purposes of the special warranty of title set out in the General Assignment.

3.4    Remedies for Title Defects. For any Title Defect properly asserted by Purchaser during the Due Diligence Period, subject to the termination rights of Seller pursuant to Section 3.8 hereof, Seller shall have the option, in its sole discretion, of (i) curing the Title Defect, (ii) contesting the Title Defect or the proposed Title Defect Amount, or (iii) reducing the Purchase Price by the proposed Title Defect Amount less the Individual Title Defect Deductible (a “Title Defect Adjustment”); provided that if the Title Defect Adjustment for any Title Defect Property exceeds 50% of the Allocated Value for such Property, Seller shall have the option of removing the affected Property from the transaction contemplated herein and reducing the Purchase Price by the Allocated Value thereof.

3.5    Procedure for Resolving Title Defects. With respect to Title Defects properly and timely asserted by Purchaser and contested by Seller as to existence or the Title Defect Amount attributable thereto, the following procedures shall apply.

3.6    Value of Defects. Subject to the provisions of Section 3.5.2, the adjustment to the Purchase Price for a Title Defect shall be determined as follows:

3.7    Interest Additions. If Seller discovers (i) that Seller owns an interest in a Property that is not described in Exhibit A but will be conveyed to Purchaser at Closing, and such additional Property is free of Title Defects or has a Title Defect Amount less than the Title Defect Deductible, or (ii) that the actual Net Revenue Interest for a Well described on Exhibit B is greater than the Net Revenue Interest shown for such Well on Exhibit B, and such Well is free of Title Defects or has a Title Defect Amount less than the Title Defect Deductible (in each case, an “Interest Addition”), then Seller shall, from time to time, have the right to give Purchaser written notice of such Interest Additions (“Interest Addition Notice”), as soon as practicable but no later than the end of the Due Diligence Period, stating with reasonable specificity the Property affected, the particular Interest Addition claimed, and Seller’s good faith estimate of the value of the additional Property or the amount by which the Additional Interest increases the value of the affected Property over and above the Allocated Value for such Property (“Interest Addition Value”). If Purchaser agrees with the existence of the Interest Addition and Seller’s good faith estimate of the Interest Addition Value, then the Interest Addition Value shall be either (i) offset by the value of the identified Title Defects, or (ii) if the aggregate Interest Addition Value exceeds the amount of the aggregate adjustment to the Purchase Price attributable to Title Defects, the amount of such difference (an “Interest Addition Payment”) shall be paid by Purchaser to Seller as an adjustment to the Purchase Price at the Closing.

If Purchaser contests the existence of the Interest Addition or Seller’s good faith estimate of the Interest Addition Value, then Purchaser shall so notify Seller in writing on or before five (5) business days after receipt of the Interest Addition Notice (“Interest Addition Rejection Notice”). The Interest Addition Rejection Notice shall state with reasonable specificity the basis of Purchaser’s rejection of the Additional Interest or the Interest Addition Value. No later than five (5) business days following delivery of the Interest Addition Rejection Notice, representatives of Purchaser and Seller, knowledgeable in title matters, shall meet and either (i) agree to mutually reject the Interest Addition, in which case Seller shall waive the Interest Addition, or (ii) agree on the validity of such Interest Addition and the Interest Addition Value, in which case Seller shall be entitled to an increase in the Aggregate Title Deductible or an Interest Addition Payment, as applicable. If the Parties cannot agree on either option (i) or (ii) in the preceding sentence, the Interest Addition subject to the Interest Addition Rejection Notice shall be submitted to dispute resolution in accordance with the procedures set forth in Section 3.9. If Purchaser fails to timely deliver an Interest Addition Rejection Notice, Purchaser shall be deemed to have accepted the validity of the Interest Addition and the Interest Addition Value, and Seller shall be entitled to either an increase in the Aggregate Title Deductible or an Interest Addition Payment, as applicable.

3.8    Right to Terminate Agreement. Notwithstanding anything in Article 3, Article 4 or Article 5, in the event the sum of the adjustments to the Purchase Price attributed to Title Defects, Environmental Defects, and Casualty Losses (as hereinafter defined) equals or exceeds twenty percent (20%) of the Purchase Price, and Seller elects not to cure or is unable to cure such Title Defects, Environmental Defects, or Casualty Losses, then Seller may, by written notice given to Purchaser not less than two (2) business days prior to the Closing Date, elect to terminate this Agreement without liability to Purchaser, in which case Purchaser shall be entitled to a refund of the Performance Deposit.

3.9    Expert Determination.

landmen, or any petroleum engineer or environmental consultant mutually agreed upon by the Parties or any neutral expert selected by the Defect Expert.

3.10    Preferential Purchase Rights and Consents to Assign.

preferential right to purchase or similar right, Seller shall be entitled to retain all proceeds paid for the affected Asset by the person exercising such preferential right to purchase or similar right. Such a reduction of the Purchaser Price shall be without regard to the Individual Title Defect Deductible otherwise applicable to individual Title Defects under Section 3.2.4 or the 2.5% Aggregate Title Deductible otherwise applicable to Title Defect Amounts for uncured Title Defects under Section 3.5.2, and no reduction of the Purchase Price pursuant to this Section 3.10.2 shall be taken into account in determining whether the Aggregate Title Deductible has been met. If Purchaser purchases at the Closing an Asset burdened by a preferential right to purchase or similar right that has not been exercised as of the Closing Date, regardless of whether the time period for the exercise of such right has expired, no reduction of the Adjusted Purchase Price paid at the Closing shall be made with respect thereto. If, for any reason, such preferential right to purchase or similar right is successfully exercised by the holder thereof after the Closing, Purchaser shall be entitled to retain all proceeds paid for the affected Asset by the holder of the relevant preferential right to purchase or similar right.

4.1    Casualty Loss. If, prior to the Closing, any of the Assets are substantially damaged or destroyed by fire, explosion, accident, act of the public enemy, act of God, or other similar event or occurrence (“Casualty Loss”), Seller shall notify Purchaser promptly after Seller learns of such event. Seller shall have the right, but not the obligation, to cure any such Casualty Loss by repairing such damage or, in the case of Personal Property or fixtures, replacing the damaged Assets with equivalent items, no later than the Closing Date. If any Casualty Loss exists at the Closing, Purchaser shall proceed to purchase the damaged Assets, and the Purchase Price shall be reduced by the aggregate reduction in value of all Assets affected by such Casualty Loss, as determined by the mutual agreement of the Parties; provided that if the Parties are unable to agree on such amount prior to the Closing, then such determination shall be made by the Defect Expert as provided in Section 3.9 above. Notwithstanding anything to the contrary contained in this Section 4.1, Seller shall be entitled to retain all insurance proceeds and claims against other parties relating to any such Casualty Loss. For purposes of this provision, normal wear and tear shall not be considered a Casualty Loss.

5.1    Physical Condition of the Assets. The Assets have been used for Hydrocarbon drilling and production operations and various related oil field operations. Physical changes in or under the Properties or adjacent lands may have occurred as a result of such uses. The Properties also may contain buried pipelines and other equipment, whether or not of a similar nature, the locations of which may not now be known by Seller or be readily apparent by a physical inspection of the Property. Purchaser understands that Seller may not have the requisite information with which to determine the exact nature or condition of the Properties or the effect any such use has had on the physical condition of the Assets. In addition, Purchaser acknowledges that some oil field production equipment may contain asbestos and/or naturally occurring radioactive material (“NORM”). In this regard, Purchaser expressly understands that NORM may affix or attach itself to the inside of wells, materials, and equipment as scale or in other forms, and that the wells, materials, and equipment located on the Assets may contain NORM and that NORM containing materials may be buried or have been otherwise disposed of on the Assets. Purchaser also expressly understands that

special procedures may be required for the removal and disposal of asbestos and NORM from the Assets where it may be found. The statements in this Section 5.1 are intended as disclosures of possible conditions existing on the Properties and not an admission or acknowledgment that any such conditions actually exist.

5.2    Environmental Assessment. Except as identified on Schedule 6.2.7, to the knowledge of Seller, there are no environmental conditions which will have a material adverse impact on the Assets.

5.3    Environmental Defect Notice. If Purchaser, in its sole discretion, determines, as a result of Purchaser’s Environmental Assessment, that there exists or may exist an Environmental Defect, Purchaser may notify Seller thereof in writing as soon as reasonably practical after its discovery, but in any event before the end of the Due Diligence Period (the “Environmental Defect Notice”). Any notice provided hereunder shall include appropriate evidence to substantiate Purchaser’s position, including a description of the Environmental Defect, the Environmental Law applicable to the Environmental Defect, Purchaser’s basis for believing that Seller is in violation of such Environmental Law, the portion of the Assets affected by the Environmental Defect, a detailed description, prepared by Purchaser’s Environmental Consultant, of the proposed methods and scope

of the Remediation (as hereinafter defined) required, the proposed Remediation Amount (as hereinafter defined) attributable thereto, and all assumptions relied upon by Purchaser’s Environmental Consultant in preparing such summary and estimate. Purchaser will be deemed to have conclusively waived any Environmental Defect discovered by Purchaser during the Due Diligence Period and with respect to which Purchaser fails to timely and properly furnish to Seller an Environmental Defect Notice.

5.4    Remedies for Environmental Defects. For any Environmental Defect properly asserted by Purchaser during the Due Diligence Period, subject to the termination rights of Seller pursuant to Section 3.8, Seller shall have the option, in its sole discretion, of (i) remedying the Environmental Defect, (ii) contesting the Environmental Defect or the Remediation Amount, or (iii) reducing the Purchase Price by an amount equal to the proposed Remediation Amount less the Individual Environmental Defect Deductible (“Environmental Defect Adjustment”); provided that if the asserted Environmental Defect Adjustment for any Property exceeds 50% of the Allocated Value for such Property, Seller shall have the option of removing the affected Property from the transaction contemplated herein and reducing the Purchase Price by the Allocated Value thereof. If the Environmental Defect Adjustment for any Property, as determined under this Article 5.5, exceeds 50% of the Allocated Value for such Property, Purchaser shall have the option of removing the affected Property from the transaction contemplated herein and reducing the Purchase Price by the Allocated Value thereof.

5.5    Procedure for Resolving Environmental Defects. With respect to Environmental Defects properly and timely asserted by Purchaser as provided herein, the following procedures shall apply.

all of the Properties exceeds an amount equal to two and one-half percent (2.5%) of the Purchase Price (the “Aggregate Environmental Deductible”).

6.2.9    Material Contracts. Schedule 6.2.9 sets forth a list of all Material Contracts (as hereinafter defined) that exist as of the date of this Agreement. Except as set forth on Schedule 6.2.9, each Material Contract is a valid and binding agreement of Seller, enforceable against Seller in accordance with its terms, and, to Seller’s knowledge,

enforceable against each other party thereto in accordance with its terms, subject, in each case, to (i) applicable bankruptcy, insolvency, reorganization, moratorium and other similar laws of general application with respect to creditors, (ii) general principles of equity and (iii) the power of a court to deny enforcement of remedies generally based upon public policy.

8.1    Operations. From the date of this Agreement until the Closing (the “Interim Period”), to the extent Seller can exert influence over such matters, Seller will use reasonable commercial efforts to see that the Properties not operated by Seller are maintained in full force and effect and are operated in a good and workmanlike manner and in accordance with the terms and conditions of the applicable oil, gas, and mineral leases, Existing Contracts, and all Applicable Laws. Seller, as to the portion of the Properties which Seller now operates, shall continue to operate the same in a good and workmanlike manner and in accordance with the terms and conditions of the applicable oil, gas and mineral leases, the Existing Contracts, and all Applicable Laws, until such operations are turned over to and become the responsibility of Purchaser. However, Seller will not have any obligation to operate any portion of the Properties after the expiration of the Interim Period except as provided for in Section 8.3. Subject to the terms of Section 8.3, Seller will pay its proportionate share of all costs and expenses incurred in connection with Properties for which invoices are received prior to the Closing Date. During the Interim Period, Seller will, to the extent Seller controls the

operation of any of the Properties, maintain the lease equipment in the same condition, working order, and state of repair as currently exists, subject to ordinary wear and tear. During the Interim Period and thereafter until operations are transferred to Purchaser or the duly elected or appointed successor operator, without the prior written consent of Purchaser, Seller will not (i) cause the Properties to be developed, maintained or operated in a manner substantially inconsistent with prior operations, (ii) abandon any part of the Properties, (iii) commence any operation on the Properties anticipated to cost, as to Seller’s interest in the Properties, in excess of $250,000 per operation, except emergency operations, operations required under presently existing contractual obligations, the outstanding AFE’s and other commitments described in Schedule 8.1, and operations undertaken to avoid any penalty provision of any Existing Contract or order (with respect to emergency operations, Seller shall notify Purchaser of said emergency as soon as reasonably practical), or (iv) convey or dispose of any part of the Properties (other than Personal Property and equipment replaced with items of comparable or superior quality and Hydrocarbons produced from the Properties in the ordinary course of business).

8.2    Contracts. During the Interim Period, Seller will not, without the prior written consent of Purchaser, enter into any agreement (i) that would be a Material Contract if existing on the date of this Agreement, or (ii) amending, modifying, or terminating any of the Material Contracts.

8.3    Compensation of Seller. With respect to those Properties operated by Seller, (i) Seller shall operate such Properties for the benefit of Purchaser during the period from the Effective Date through the date(s) when the operation of such Properties is turned over to, and becomes the responsibility of, Purchaser or the duly elected or appointed successor operator (the “Operations Period”), (ii) Seller shall be entitled to retain all amounts paid or owing to Seller by non-operators pursuant to the terms of the existing operating or similar agreements or otherwise required by law, (iii) Purchaser shall pay to Seller an amount equal to (A) the overhead charge attributable to Seller’s Working Interest in each such Property that would be payable to the operator pursuant to the terms of existing operating or similar agreements or otherwise required by law if Seller were a non-operator, or (B) if Seller owns 100% of the working interest in such Property, a per month overhead charge equal to $7000 per drilling well and $700 per producing well, all in accordance with the 1984 COPAS Onshore Model Accounting Procedure, which is hereby incorporated by reference (with the salaries, wages and personal expenses of technical employees employed directly on the Property, or temporarily or permanently assigned to and directly employed in the operation of the Property, charged as a direct cost and excluded from such overhead charges), and (iv) all reasonable and necessary expenses attributable to Seller’s Working Interest incurred by Seller in operating, protecting, and maintaining the subject Properties. Any such charges and expenses shall be recovered by Seller as part of the Closing or post-Closing adjustments, as appropriate. Except in the event of an emergency, Seller will have no obligation to make capital expenditures or extraordinary operating expenditures in connection with the Properties during the Operations Period. Additionally, during the Operations Period, Seller may require Purchaser to prepay, on a monthly basis, Purchaser’s share of any and all expenses estimated by Seller to become due with respect to operations on the Properties operated by Seller during the next succeeding month. If Purchaser is ultimately elected as operator of the Properties which Seller currently operates, Purchaser will additionally reimburse Seller for the amounts of any unpaid operating expenses and capital expenditures of other working interests owners paid by Seller and attributable to operations during the Operations Period.

8.4    Permissions. During the Interim Period, Seller shall use reasonable efforts to obtain all permissions, approvals, and consents by Federal, state and local governmental authorities and others as may be required to consummate the transactions contemplated by this Agreement (excluding governmental permissions, approvals and consents which are customarily obtained after the assignment of an oil and gas interest which shall be the responsibility of Purchaser to obtain).

8.5    Defaults. Seller shall give prompt written notice to Purchaser of any notice of material default (or written threat of material default, whether disputed or denied by Seller) received or given by Seller subsequent to the Effective Date under any instrument or agreement affecting the Properties to which Seller is a party or by which Seller or any of the Assets is bound.

8.6    Operatorship. It is understood that in most (if not all) of the operating agreements covering any of the Properties, Seller does not retain the right to transfer operation of such Properties that are the subject of such operating agreements to a purchaser of Seller’s interests. Notwithstanding the foregoing, at the Closing Seller will execute and deliver to Purchaser such change of operator forms as may be required by the applicable Governmental Bodies reflecting Purchaser as successor operator; however, Purchaser shall be solely responsible for obtaining approval to succeed Seller as operator from both the non-operators of each such Property and from the applicable Governmental Body. If requested by Purchaser, Seller shall use reasonable commercial efforts to assist Purchaser in securing the consent of all interested parties to Purchaser’s election as operator of all of the Properties for which Seller is the current operator, but in no event shall Seller be required to devote substantial employee time or expend funds in connection therewith, nor shall Seller have any liability or responsibility with respect thereto. Purchaser shall have the right to obtain agreements from such interested parties after the transaction contemplated by this Agreement has been publicly announced and thereafter during the Interim Period.

8.7    Geological and Geophysical Information. During the Interim Period, with respect to any right, title, and interest of Seller in any item of geological and geophysical information:

9.1    Return of Data.

12.1    Time and Place of the Closing. The consummation of the transactions contemplated by this Agreement (the “Closing”) shall occur at 10:00 a.m., Central Time, on May 23, 2014 (such date, or any subsequent date agreed to by the Parties pursuant to Section 12.2, the “Closing Date”).

Each Party also agrees to cooperate with each other by providing reasonable information which may be required by the other Party for the purpose of administering the Assets and preparing or reviewing the Post-Closing Adjustment Statement.

14.1    Right of Termination. This Agreement may be terminated at any time at or prior to the Closing only:

14.2    Effect of Termination. If this Agreement is terminated pursuant to Section 14.1 above, this Agreement shall become void and of no further force or effect (except for the provisions of the final sentence of Section 3.1 and Sections 5.2.2, 9.2, 16.10, and this Section 14.2, which shall

continue in full force and effect). If this Agreement is terminated pursuant to Section 14.1.1 or Section 14.1.4, neither Party shall have any further liability to the other as the result of such termination. If this Agreement is terminated by Seller pursuant to Section 14.1.2, then Seller shall have the option of retaining the Performance Deposit as liquidated damages pursuant to Section 2.3, or proceeding against Purchaser for such damages as may be determined by a court of competent jurisdiction. If this Agreement is terminated by Purchaser pursuant to Section 14.1.3, then the Performance Deposit shall be returned to Purchaser as Purchaser’s sole remedy, with all other remedies being expressly waived by Purchaser. Notwithstanding anything to the contrary contained in this Agreement, upon any termination of this Agreement pursuant to Section 14.1, Seller shall be free immediately to enjoy all rights of ownership of the Assets and to sell, transfer, encumber, or otherwise dispose of the Assets to any party without any restriction under this Agreement; and Purchaser shall be liable for all actual, incidental, and consequential damages (including, without limitation, lost profits) if it attempts to interfere in any way with any such enjoyment or action by Seller.

15.1    Apportionment of Ad Valorem and Property Taxes. All ad valorem taxes, real property taxes, Personal Property taxes, and similar tax obligations (the “Property Taxes”) with respect to the Assets for the tax period in which the Effective Date occurs shall be apportioned, based on the Effective Date, between Seller and Purchaser and, if already paid by Seller, an appropriate increase in the Purchase Price shall be made pursuant to Section 2.4.6. If such Property Taxes are not already paid, but the tax liability is known or can be reasonably estimated, Seller’s portion of such Property Taxes shall be credited to Purchaser’s account pursuant to Section 2.4.12. Purchaser shall pay or cause to be paid to the taxing authorities all Property Taxes of which it has knowledge not already paid relating to the tax period in which the Effective Date occurs and if appropriate adjustments to the Purchase Price pursuant to Section 2.4 were not made at the Closing or in connection with the Post-Closing Adjustment Statement, Purchaser shall invoice Seller (with copies of applicable tax bills and assessments to confirm same) for Seller’s apportioned shares of such Property Taxes, and Seller shall pay the same within thirty (30) days of receipt of said notice. Purchaser shall defend, indemnify, and hold Seller harmless with respect to the payment of such Property Taxes of which Purchaser has knowledge and which Purchaser is obligated to pay to the applicable taxing authorities (including any interest or penalties assessed thereon), provided Seller pays its share (as apportioned hereunder) within thirty (30) days of being properly invoiced (with accompanying documents to support the invoice) by Purchaser. For the tax period in which the Effective Date occurs, Seller agrees (i) to forward immediately to Purchaser copies of all Property Tax reports and returns received by Seller after the Closing and (ii) to provide Purchaser with appropriate information which is necessary for Purchaser to file any required Property Tax reports and returns. For non-operated Properties (except for that portion of those Property Taxes paid by Seller or others attributable to non-operated production burdens as set forth in Section 15.2 below), the Property Taxes will be allocated between Seller and Purchaser upon the receipt of joint interest billings in which such Property Taxes are charged. All tax apportionments determined under this Section 15.1 and Section 15.2 shall be deemed a final settlement of Property Taxes between the Parties. Notwithstanding the foregoing, Seller or Purchaser may contest with the appropriate taxing authority the amount of or liability for any Property Tax apportioned to it pursuant to this Section 15.1. The Party pursuing the contest shall indemnify the other Party from and against all Costs incurred by the other Party in connection with the contest, and upon final settlement or resolution of the contest, the economic

burden of the contested tax shall be adjusted among the parties in a manner consistent with the intent of this Section 15.1.

15.2    Taxes Paid for Others. To the extent Purchaser has a right to do so, Purchaser agrees to withhold from future income distributions to royalty owners, overriding royalty interest owners, and other production burden holders as to the Assets amounts sufficient to reimburse Seller for various taxes (e.g., Property Taxes, severance, environmental excise, etc.) paid by Seller on behalf of such interest holders while Seller owned the Assets (which shall include withholdings for co-working interest owners when Seller has paid its taxes and has not previously collected such taxes through joint interest billings). Seller will provide Purchaser with sufficient documentation to allow Purchaser to confirm amounts to be withheld and will indemnify and hold Purchaser harmless from liability for deducting such sums as directed by Seller. Purchaser agrees promptly to forward to Seller such sums which are withheld pursuant to this Section 15.2.

15.3    Sales Taxes. Purchaser shall pay, or cause to be paid, all sales, use, transfer, and similar taxes, if any, resulting from the sale and transfer of the Assets to Purchaser hereunder (including without limitation, all applicable conveyance, transfer and recording fees, and real estate transfer stamps or taxes imposed on the transfer of the Assets pursuant to this Agreement), and shall prepare and file all tax returns required to be filed with respect to such taxes.

15.4    Other Taxes. All production, severance, excise, and other similar taxes that are based upon production of, or income or revenues from, Hydrocarbons attributable to the Assets prior to the Effective Date shall be paid by Seller, and all such taxes relating to such production on or after the Effective Date shall be paid by Purchaser. The Party responsible for payment of such tax shall prepare and file all tax returns required to be filed in respect thereof. This Section 15.4 shall not apply to any tax to the extent specifically otherwise provided elsewhere in this Agreement.

15.5    Cooperation. Each Party shall cooperate with the other Party and provide the other Party with all information in its possession or to which it has access which may be reasonably required by the other Party in connection with the preparation of any tax return relating to the Assets, the audit or examination of any such returns by any tax authority, and the determination of or contest of any tax relating to the Assets. Notwithstanding anything to the contrary in this Agreement, neither Party shall be required at any time to disclose to the other Party any tax returns or other confidential tax information except to the extent required by Applicable Law or court order.

15.6    Tax Indemnity. Seller shall indemnify and hold harmless Purchaser, and Purchaser shall indemnify and hold harmless Seller, in each case with respect to the payment of any taxes, including any interest or penalties assessed thereon, for which the indemnifying Party is responsible pursuant to the provisions of this Article 15.

16.1    Entire Agreement.

16.14    Severability. If any term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the contemplated transactions is not affected in any material adverse manner to either Party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner to the end that the contemplated transactions are fulfilled to the extent possible.

16.15    Affiliate. For purposes of this Agreement, the term “Affiliate” (whether capitalized or not) shall mean, when used with respect to a person or entity, any other person or entity (i) which directly or indirectly (through one or more intermediaries) controls, or is controlled by, or is under common control with, such first mentioned person or entity, or (ii) which beneficially owns, holds, or controls fifty percent (50%) or more of the interest of such first mentioned person or entity. The term “control” (including the terms “controlled by” and “under common control with”) means the possession, directly or indirectly or as trustee or executor, of the power to direct or cause the direction of the management policies of a person or entity, whether through the ownership of stock, as trustee or executor, by contract or credit arrangement or otherwise.

16.16    Survival; Certain Limitations.

Parties under this Agreement (i) to be performed at or prior to the Closing shall expire and be of no further force or effect after the Closing, and (ii) to be performed after the Closing shall survive the Closing until barred by the applicable statutes of limitations (for this purpose, nothing contained in Article 6 or 7 shall be deemed to be a covenant).

16.17    Attorney’s Fees. Any Party successfully pursuing a claim for the enforcement of any provision of this Agreement, including, without limitation, agreements of indemnity contained herein or any of the documents to be delivered pursuant hereto, shall be entitled to recover from the unsuccessful Party reasonable attorneys’ fees, court costs, and other expenses incurred by the successful Party in such action.

16.18    Interest. In the event that either Party brings suit to collect any amount owed by the other Party hereunder, such other Party shall pay the Party bringing such suit interest on any amount so collected from the date of demand (or, if earlier, the date due) until the date of payment at the Agreed Rate.

16.19    Certain Limitations. SELLER AND PURCHASER AGREE THAT, EXCEPT FOR THE LIQUIDATED DAMAGES SPECIFICALLY PROVIDED FOR IN SECTION 2.3, AND THE POSSIBILITY OF THE RECOVERY BY SELLER OF INCIDENTAL AND CONSEQUENTIAL DAMAGES AS SPECIFICALLY PROVIDED IN SECTION 14.2, THE RECOVERY BY EITHER PARTY OF ANY DAMAGES SUFFERED OR INCURRED BY IT AS A RESULT OF ANY BREACH BY THE OTHER PARTY OF ANY OF ITS REPRESENTATIONS, WARRANTIES, COVENANTS OR OBLIGATIONS UNDER THIS AGREEMENT SHALL BE LIMITED TO THE ACTUAL DAMAGES SUFFERED OR INCURRED BY THE NONBREACHING PARTY AS A RESULT OF THE BREACH BY THE BREACHING PARTY OF ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS HEREUNDER AND IN NO EVENT SHALL THE BREACHING PARTY BE LIABLE TO THE NONBREACHING PARTY FOR ANY INDIRECT, CONSEQUENTIAL, SPECIAL, EXEMPLARY OR PUNITIVE DAMAGES (INCLUDING, WITHOUT LIMITATION, ANY DAMAGES ON ACCOUNT OF LOST PROFITS OR OPPORTUNITIES, BUSINESS INTERRUPTION OR LOST OR DELAYED PRODUCTION) SUFFERED OR INCURRED BY THE NONBREACHING PARTY AS A RESULT OF THE BREACH BY THE BREACHING PARTY OF ANY OF ITS REPRESENTATIONS, WARRANTIES OR OBLIGATIONS HEREUNDER. For purposes of the foregoing, actual damages may, however, include indirect, consequential, special, exemplary or punitive damages to the extent (i) the injuries or losses resulting in or giving rise to such damages are incurred or suffered by a person which is not Seller or Purchaser, as applicable, or its Affiliates and (ii) such damages are recovered against Seller or Purchaser, as applicable, by a person which is not Seller or Purchaser,

as applicable, or its Affiliates. This Section 16.19 shall operate only to limit a Party’s liability and shall not operate to increase or expand any contractual obligation of a party hereunder or cause any contractual obligation of a party hereunder to survive longer than provided in Section 16.16.

16.20    Exchange. Each of Seller and Purchaser shall have the right to utilize all or part of the Assets as part of a tax deferred exchange pursuant to Section 1031 of the IRC and applicable state and local tax laws. In connection with an exchange, and notwithstanding the terms of Section 16.4, all or part of Seller’s or Purchaser’s rights, as applicable, under this Agreement may be assigned, without the need for Purchaser’s or Seller’s consent, as applicable, to an intermediary, escrow agent, trustee, or other exchange accommodation party, provided that such assignment shall not relieve the assigning Party of its obligations to the other Party hereunder. The Parties shall cooperate in effecting any such exchange, including, without limitation, the execution of escrow instructions and other instruments, provided that: (i) the acquisition and exchange of any exchange property by Seller shall not impose upon Purchaser any additional financial obligation other than as set out in this Agreement; (ii) Neither Purchaser nor Seller shall have any obligation to become a holder of record title to any exchange property acquired or sold by the other Party; (iii) Seller shall indemnify and hold Purchaser harmless from any and all Costs which Purchaser incurs or to which Purchaser may be exposed as a result of Purchaser’s participation in Seller’s contemplated exchange, if any, including reasonable attorneys’ fees and costs of defense; (iv) Purchaser shall indemnify and hold Seller harmless from any and all Costs which Seller incurs or to which Seller may be exposed as a result of Seller’s participation in Purchaser’s contemplated exchange, if any, including reasonable attorneys’ fees and costs of defense; (v) the Closing shall not be delayed or affected by reason of any such exchange nor shall the consummation or accomplishment of such exchange be a condition precedent or condition subsequent to Seller’s or Purchaser’s obligations under this Agreement; (vi) neither Purchaser nor Seller shall, by this Agreement or acquiescence to any such exchange by the other Party, have its rights under this Agreement affected or diminished in any manner; and (vii) neither Purchaser nor Seller shall, by this Agreement or acquiescence to any such exchange by the other Party, be responsible for compliance with or deemed to have warranted to such other Party that such other Party’s exchange in fact complies with Section 1031 of the IRC or any state or local tax law. If any exchange contemplated by Seller or Purchaser, as applicable, should fail to occur, for whatever reason, the sale of the Assets shall nonetheless be consummated as provided herein.

IN WITNESS WHEREOF, Purchaser and Seller have executed and delivered this Agreement as of the date first written above but effective as of the Effective Date.
