Concho Resources Inc., a Delaware corporation (the “Company”), is pleased to grant you an award (the “Award”) consisting of an aggregate of <shares_awarded> performance units (each, a “Performance Unit”) that have a performance period beginning on January 1, 2019 through December 31, 2021 (the “Performance Period”). The Award is subject to your acceptance of and agreement to all the applicable terms, conditions and restrictions described in this Performance Unit Award Agreement (this “Agreement”) and the Concho Resources Inc. 2015 Stock Incentive Plan (as such plan may be amended or restated thereafter from time to time, the “Plan”). A copy of the Plan is available upon request. To the extent that any provision of this Agreement conflicts with the expressly applicable terms of the Plan, you acknowledge and agree that those terms of the Plan shall control and, if necessary, the applicable provisions of this Agreement shall be deemed amended so as to carry out the purpose and intent of the Plan. Terms that have their initial letters capitalized, but that are not otherwise defined in this Agreement, shall have the meanings given to them in the Plan in effect as of the date of this Agreement (such date the “Date of Grant”). The Performance Units contemplated herein are granted as Performance Awards under the Plan and are subject to the award limitations applicable to awards denominated in shares of the Company’s common stock (the “Common Stock”) that are set forth in Paragraph V(a) of the Plan.

This Agreement sets forth the terms of the agreement between you and the Company with respect to the Performance Units. By accepting this Agreement, you agree to be bound by all of the terms hereof.

1.    Overview of Performance Units.

(a)    Performance Units Generally. Each Performance Unit represents a contractual right to receive one share of Common Stock, subject to the terms and conditions of this Agreement; provided that, based on the achievement of the performance objective outlined in Section 2 hereof (the “Performance Objective”), the number of shares of Common Stock that may be deliverable hereunder in respect of the Performance Units may range from 0% to 300% of the number of Performance Units stated in the preamble to this Agreement (such stated number of Performance Units hereafter called the “Initial Performance Units”). Your right to receive Common Stock in respect of Performance Units is generally contingent, in whole or in part, upon (i) the achievement of the Performance Objective and (ii) except as provided in Section 4(a) or Section 5 hereof, your continued employment with the Company through the end of the Vesting Period.

1

(b)    Dividend Equivalents. With respect to each outstanding Performance Unit, the Company shall credit a book entry account with an amount equal to the amount of any cash dividend paid during the Performance Period on one share of Common Stock. The amount credited to such book entry account shall be payable to you at the same time or times, and subject to the same terms and conditions as are applicable to, your Performance Units; provided that, if more than the Initial Performance Units shall become payable in accordance with this Agreement, then the maximum amount payable in respect of such dividend equivalents shall be the amount credited to your book entry account. Dividends and distributions payable on Common Stock other than in cash shall have a value equal to the amount of such dividends reported by the issuer to its shareholders for purposes of Federal income taxation and will be addressed in accordance with Section 9 hereof.

2.    Performance Objective. The Performance Objective with respect to the Initial Performance Units is based on both (a) the Total Shareholder Return achieved by the Company relative to the Peer Companies (as defined below) for the Performance Period (the “Relative Total Shareholder Return”) and (b) the absolute annualized Total Shareholder Return achieved by the Company for the Performance Period (the “Absolute Total Shareholder Return”). “Total Shareholder Return” shall mean, as to the Company and each of the Peer Companies, the percentage rate of return shareholders receive through stock price changes and the receipt of cash dividends paid over the Performance Period, determined in accordance with the following formula: (Closing Value minus Initial Value plus Cash Dividends) divided by Initial Value, where:

Closing Value means the average of the closing stock prices of the Company or such Peer Company, as applicable, on each trading day during the period beginning on the first day of the calendar month in which the last day of the Performance Period occurs and ending on the last day of the Performance Period; provided, however, that if a Peer Company ceases to have a class of common equity securities listed to trade under Section 12(b) or Section 12(g) of the Exchange Act during the Performance Period (determined after any applicable adjustment by the Committee pursuant to Section 9 hereof), then the Total Shareholder Return for such Peer Company shall be determined by the Committee as provided in the preceding provisions of this sentence but, from and after the date of such cessation, the price per share of such Peer Company’s common stock shall be deemed to be equal to the price per share of such common stock immediately prior to such cessation increased by the interest that would be earned on such amount if it were invested in U.S. Treasury securities of approximate equal duration to the portion of the Performance Period remaining after such cessation.

Notwithstanding the foregoing, if Total Shareholder Return for the Company and the Peer Companies is required to be determined for purposes of Section 5 hereof, then the Closing Value shall be determined as described above, except that (i) the last day of the Performance Period shall be deemed to be the Change of Control Date and the Closing Value with respect to the Peer Companies shall be based on the 30-day period ending on the date of such termination of employment, and (ii) the Closing Value with respect to the Company shall mean the fair market value (as determined in good faith by the Committee) of the consideration received by the stockholders of the Company with respect to each share of Common Stock as of the effective time of the Change of Control; provided, however, that if such Change of Control is effected in a manner that does not result in the

2

stockholders of the Company receiving consideration in exchange for their Common Stock, then such Closing Value shall mean the average of the closing stock prices of the Company on each trading day during the 30-day period immediately preceding the date of the Change of Control Date (as defined in Section 5 hereof).

In addition, if Total Shareholder Return for the Company and the Peer Companies is required to be determined for purposes of Section 4(a) or 4(b) hereof, then the Closing Value shall be determined as described above, except that the last day of the Performance Period shall be deemed to be the Termination Date (as defined in Section 4(a) hereof) and the Closing Value shall be based on the 30-day period ending on the date of such termination of employment.

Initial Value means the average of the closing stock prices of the Company or such Peer Company, as applicable, on each trading day in the calendar month immediately preceding the first day of the Performance Period. The Initial Value of the Common Stock to be used to determine the Company’s Total Shareholder Return over the Performance Period is $             per share.

Cash Dividends means the aggregate amount of cash dividends per share paid over the Performance Period by the Company or such Peer Company, as applicable.

Achievement with respect to the portion of the Performance Objective that is based on Relative Total Shareholder Return shall be determined by the Committee based on the Company’s relative ranking in respect of the Performance Period with regard to Total Shareholder Return as compared to Total Shareholder Return of the Peer Companies, and shall be a percentage determined in accordance with the table set forth in Appendix A hereto. A company shall be a “Peer Company” if it is one of the companies listed on Appendix A hereto. Achievement with respect to the portion of the Performance Objective that is based on Absolute Total Shareholder Return shall be determined by the Committee based on the Company’s annualized Total Shareholder Return achieved over the Performance Period, and shall be a percentage determined in accordance with the provisions set forth in Appendix A hereto. As soon as administratively practicable following the end of the Performance Period (but in no event later than the 15^th day of the third calendar month following the calendar month in which the Performance Period ends), the Committee shall certify whether and to the extent that the Performance Objective has been achieved and will determine the number of Performance Units, if any, determined to be earned for the Performance Period (which number of Performance Units shall equal the product of the Initial Performance Units (subject to adjustment as set forth in Section 9 hereof) multiplied by the percentage determined with respect to Relative Total Shareholder Return pursuant to the table set forth in Appendix A hereto multiplied by the percentage determined with respect to Absolute Total Shareholder Return in accordance with the provisions set forth in Appendix A hereto). The number of Performance Units, if any, determined by the Committee to be earned pursuant to the preceding provisions of this Section 2 shall be referred to as the “Earned Performance Units.”

3.    Conversion of Performance Units; Delivery and Vesting of Restricted Stock with respect to Performance Units.

(a)    Conversion of Performance Units. Unless an earlier date applies pursuant to Section 5(d) hereof, payment in respect of Earned Performance Units (and any related dividend equivalents) shall be made not later than the 15^th day of the third calendar month following the calendar month in which the Performance Period ends. All payments in respect of Earned Performance Units shall be made in the form of time-based Restricted Stock that will be subject to the Forfeiture Restrictions in Section 3(b). Neither this Section 3 nor any action taken pursuant to or in accordance with this Section 3 shall be construed to create a trust of any kind. Any shares of Common Stock issued to you pursuant to this Agreement shall be in book entry form registered in your name. Any fractional Earned Performance Units shall be rounded up to the nearest whole share of Common Stock.

(b)    Forfeiture Restrictions. The Restricted Stock issued hereunder in settlement of Earned Performance Units may not be sold, assigned, pledged, exchanged, hypothecated or otherwise transferred, encumbered or disposed of, and in the event of termination of your employment with the Company for any reason other than as described in Section 4(a) or (b) below, you shall, for no consideration, forfeit to the Company all Restricted Stock. The prohibition against transfer and the obligation to forfeit and surrender the Restricted Stock to the Company upon termination of employment as provided in the preceding sentence are herein referred to as the “Forfeiture Restrictions.” The Forfeiture Restrictions shall be binding upon and enforceable against any transferee of the Restricted Stock.

(c)    Lapse of Forfeiture Restrictions. Provided that you have been continuously employed by the Company from the Date of Grant through the applicable lapse dates set forth in the following schedule, the Forfeiture Restrictions shall lapse with respect to a percentage of the Restricted Stock determined in accordance with the following schedule: the Forfeiture Restrictions shall lapse over a period of five (5) years commencing on the fifth (5^th) anniversary of the Date of Grant (the “Vesting Period”) at a rate of 20% per year, with the Forfeiture Restrictions applicable to 20% of the total number of shares of Restricted Stock lapsing on the sixth (6^th) anniversary of the Date of Grant, and the Forfeiture Restrictions with respect to an additional 20% of the Restricted Stock lapsing annually thereafter until the tenth (10^th) anniversary of the Date of Grant.

(d)    Certificates. A certificate evidencing the Restricted Stock shall be issued by the Company in the your name, pursuant to which you shall have all of the rights of a stockholder of the Company with respect to the Restricted Stock, including, without limitation, voting rights and the right to receive dividends (provided, however, that dividends paid in shares of the Company’s stock shall be subject to the Forfeiture Restrictions and further provided that dividends that are paid other than in shares of the Company’s stock shall be paid no later than the end of the calendar year in which the dividend for such class of stock is paid to stockholders of such class or, if later, the 15th day of the third month following the date the dividend is paid to stockholders of such class of stock). Notwithstanding the foregoing, the Company may, in its discretion, elect to complete the delivery of the Restricted Stock by means of electronic, book-entry statement, rather than issuing physical share certificates. You may not sell, transfer, pledge, exchange, hypothecate or otherwise dispose of the stock until the Forfeiture Restrictions have expired, and a breach of the

4

terms of this Agreement shall cause a forfeiture of the Restricted Stock. The certificate, if any, shall be delivered upon issuance to the Secretary of the Company or to such other depository as may be designated by the Committee as a depository for safekeeping until the forfeiture of such Restricted Stock occurs or the Forfeiture Restrictions lapse pursuant to the terms of the Plan and this Agreement. At the Company’s request, you shall deliver to the Company a stock power, endorsed in blank, relating to the Restricted Stock. Upon the lapse of the Forfeiture Restrictions without forfeiture, the Company shall cause a new certificate or certificates to be issued without legend (except for any legend required pursuant to applicable securities laws or any other agreement to which you are a party) in your name in exchange for the certificate evidencing the Restricted Stock or, as may be the case, the Company shall issue appropriate instructions to the transfer agent if the electronic, book-entry method is utilized.

4.    Termination of Employment.

(a)    Termination without Cause. In the event that your employment with the Company terminates during the Performance Period due to your termination of employment by the Company without Cause (as defined in the Severance Plan (as defined below)) (and not by reason of your death or Disability (as in the Severance Plan)), then you shall be deemed to have earned, as of the date of your termination of employment (the “Termination Date”), that number of Performance Units equal to the product of (i) and (ii), where:

Any portion of the Performance Units that do not become earned and payable in accordance with the preceding sentence shall terminate and automatically be cancelled as of the Termination Date. Distribution of shares of Common Stock in respect of the Performance Units determined to be earned by reason of this Section 4(a) shall be made made not later than the 15^th day of the third calendar month following the calendar month in which the Termination Date occurs.

In the event that your employment with the Company terminates following the Performance Period and prior to the end of the Vesting Period due to your termination of employment by the Company without Cause (and not by reason of your death or Disability), then the Forfeiture Restrictions shall lapse with respect to a pro-rated number of then unvested Restricted Stock issued pursuant to Section 3(a) based upon the number of days you were employed by the Company during the period commencing the Date of Grant through the Termination Date divided by 3,653.

5

(b)    Death or Disability. In the event that your employment with the Company terminates during the Performance Period due to your death or Disability, then you shall be deemed to have earned, as of the Termination Date, that number of Performance Units equal to the number of Earned Performance Units that you would have earned in accordance with Section 2 hereof assuming that (A) the Performance Period ended on the Termination Date and (B) the determination of whether, and to what extent, the Performance Objective is achieved is based on the higher of the target level of performance and the actual performance against the stated performance criteria through the Termination Date. Any portion of the Performance Units that do not become earned and payable in accordance with the preceding sentence shall terminate and automatically be cancelled as of the Termination Date. Distribution of shares of Common Stock in respect of the Performance Units (and any related dividend equivalents) that become earned and/or payable by reason of this paragraph shall be made made not later than the 15^th day of the third calendar month following the calendar month in which the Termination Date occurs.

(c)    Other Termination of Employment. Unless otherwise determined by the Committee at or after grant, in the event that your employment with the Company terminates prior to the end of the Performance Period for any reason other than those listed in Section 4(a) or 4(b) hereof, all of your Performance Units shall terminate and automatically be canceled upon such termination of employment. In addition, any shares of Restricted Stock issued pursuant to Section 3(a) with respect to which the Forfeiture Restrictions do not lapse in accordance with the preceding provisions of Section 4(a) or Section 4(b) shall be forfeited to the Company for no consideration as of the date of the termination of your employment with the Company.

For all purposes of this Agreement, you will be considered to have terminated from employment with the Company when you incur a “separation from service” within the meaning of Section 409A(a)(2)(A)(i) of the Code and applicable administrative guidance thereunder; provided, however, that whether such a separation from service has occurred shall be determined based upon a reasonably anticipated permanent reduction in the level of bona fide services to be performed to no more than 49% of the average level of bona fide services provided in the immediately preceding 36 months.

5.    Change of Control. Notwithstanding the provisions of Section 1 through Section 4 hereof or the terms of any Employment Agreement between you and the Company or any Affiliate, if you have been continuously employed from the grant date specified above until the date that a Change of Control (as in the Severance Plan) occurs (the “Change of Control Date”), then upon the occurrence of a Change of Control your rights in respect of the Performance Units shall be determined as provided in Section 5(a) hereof.

6

(a)    Continuous Employment. If a Change of Control occurs prior to the end of the Performance Period and your employment has not terminated prior to the Change of Control Date, then on the Change in Control Date, your outstanding Performance Units will be automatically converted into a number of time-based Restricted Stock that will vest, subject solely to your continued employment, over the Vesting Period in accordance with Section 3(c). The number of such time-based Restricted Stock will be equal to the number of Performance Units that would have become Earned Performance Units in accordance with the provisions of Section 2 hereof assuming that:

(i)    the Performance Period ended on the Change of Control Date; and

(ii)    the determination of whether, and to what extent, the Performance Objective is achieved is based on the actual performance against the stated performance criteria through the Change of Control Date.

In the event your Performance Units are converted into time-based Restricted Stock pursuant to this Section 5(a) or a Change of Control occurs after the end of the Performance Period and prior to the end of the Vesting Period, and your employment is terminated as a result of a Qualifying Termination (as defined in the Severance Plan) within the two-year period beginning on the Change of Control Date, 100% of your then-unvested and outstanding portion of this Award shall immediately vest and become payable as of your Termination Date.

(b)    Termination of Employment Upon Change of Control. If a Change of Control occurs during the Performance Period and your employment is terminated upon the Change of Control Date as a result of a Qualifying Termination, then you will be issued a number of shares of Common Stock equal to the number of Performance Units that would have become Earned Performance Units in accordance with the provisions of Section 2 hereof assuming that:

(i)    the Performance Period ended on the Change of Control Date; and

(ii)    the determination of whether, and to what extent, the Performance Objective is achieved is based on the actual performance against the stated performance criteria through the Change of Control Date.

If a Change of Control occurs after the end of the Performance Period and prior to the end of the Vesting Period and your employment is terminated upon the Change of Control Date as a result of a Qualifying Termination, 100% of your then-unvested and outstanding portion of this Award shall immediately vest and become payable as of your Termination Date.

(c)    Time and Form of Payment. Any shares of Common Stock issuable pursuant to Section 5(a) shall be issued at the time provided in Section 3 hereof, or, if sooner, immediately upon your Termination Date. Any shares of Common Stock issuable pursuant to Section 5(b) shall be issued immediately following (and not later than five business days after) the Change of Control Date and shall be fully earned and freely transferable as of the Change of Control Date. Notwithstanding anything else contained in this Section 5 to the contrary (other than Section 5(d)), if the Change of Control involves a merger, reclassification or other reorganization or business

7

combination pursuant to which the Common Stock is exchanged for or converted to stock of the surviving or continuing corporation in such transaction, the successor or continuing entity to the Company or the direct or indirect parent of the Company (collectively, the “Successor Corporation”), then you shall receive, instead of each share of Common Stock otherwise deliverable hereunder, the same consideration (whether stock, cash or other property) payable or distributable in such transaction in respect of a share of Common Stock. Any property distributed pursuant to this Section 5(c), whether in shares of the Successor Corporation or otherwise, shall in all cases be freely transferable without any restriction (other than any such restriction that may be imposed by applicable law), and any securities issued hereunder shall be registered to trade under the Exchange Act, and shall have been registered under the Securities Act of 1933, as amended (the “Securities Act”).

(d)    Alternative Form of Payment. Notwithstanding anything else contained in this Section 5 to the contrary, the Committee may elect, at its sole discretion by resolution adopted prior to the Change of Control Date, to have the Company satisfy your rights in respect of the Performance Units (as determined pursuant to the foregoing provisions of this Section 5), in whole or in part, by having the Company make a cash payment to you within five business days of the Change of Control Date in respect of all such Performance Units or such portion of such Performance Units as the Committee shall determine. Any cash payment for any Performance Unit shall be equal to the Fair Market Value of the number of shares of Common Stock into which it would convert, determined on the Change of Control Date.

6.    Clawback and Forfeiture under Certain Circumstances. Notwithstanding any provisions in this Agreement to the contrary, any portion of the payments and benefits provided under this Agreement or the sale of shares of Common Stock shall be subject to a clawback to the extent necessary to comply with applicable law including, without limitation, the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act or any Securities and Exchange Commission rule. In addition, notwithstanding any provisions herein to the contrary, the Committee may terminate your Award if it determines that you have engaged in conduct that would permit the Company to terminate your employment for cause. For purposes of the preceding sentence, the term “cause” has the meaning assigned to such term in your employment agreement with the Company or an Affiliate; provided, however, that in the absence of such an employment agreement or if such employment agreement does not define the term “cause,” then “cause” means a determination by the Company that you have (a) engaged in conduct that is injurious (monetarily or otherwise) to the Company or any Affiliate (including, without limitation, misuse of any of the Company’s funds or other property), (b) been convicted of, or pleaded no contest to, or received adjudicated probation or deferred adjudication in connection with any felony or any other crime involving fraud, dishonesty or moral turpitude, (c) breached any material provision of the Plan, this Agreement or any other written agreement or corporate policy or code of conduct established by the Company or its Affiliates, (d) engaged in gross negligence or willful misconduct in the performance of your duties, or (e) refused without proper legal reason to perform your duties.

7.    Nontransferability of Awards.

9.    Adjustments in Respect of Performance Units. In the event of any common stock dividend or common stock split, recapitalization (including, but not limited to, the payment of an extraordinary dividend), merger, consolidation, combination, spin-off, distribution of assets to stockholders, exchange of shares, or other similar corporate change with regard to the Company or any Peer Company (other than the payment of cash dividends), appropriate adjustments shall be made by the Committee to the Initial Value of the corresponding common stock, and, if any such event occurs with respect to the Company, in the aggregate number of Performance Units subject to this Agreement. The Committee’s determination with respect to any such adjustment shall be conclusive.

10.    Effect of Settlement. Upon conversion into shares of Restricted Stock (or Successor Corporation common stock) pursuant to Section 3 or Section 5 hereof, a cash settlement of your rights, at the election of the Committee at its sole discretion pursuant to Section 5(d) hereof, or a combination of the issuance of Restricted Stock and the payment of cash in accordance with any applicable provisions of this Agreement, all of your Performance Units subject to the Award shall be cancelled and terminated. If and to the extent that you are still employed at the end of the Performance Period, any portion of your Performance Units that have not become earned in accordance with the terms of this Agreement shall be cancelled and terminated.

The parties to this Agreement shall be entitled to recover from each other reasonable attorneys’ fees incurred in connection with the enforcement of the terms and provisions of this Agreement whether by an action to enforce specific performance or for damages for its breach or otherwise.

13.    Information Confidential. As partial consideration for the granting of the Award hereunder, you hereby agree with the Company that you will keep confidential all information and knowledge, except that which has been disclosed in any public filings required by law, that you have relating to the terms and conditions of this Agreement; provided, however, that such information may be disclosed as required by law and may be given in confidence to your spouse, tax and financial advisors, or to a financial institution to the extent that such information is necessary to secure a loan.

14.    Payment of Taxes. The Company may from time to time require you to pay to the Company (or an Affiliate if you are an employee of an Affiliate) the amount that the Company deems necessary to satisfy the Company’s or its Affiliate’s current or future obligation to withhold federal, state or local income or other taxes that you incur as a result of the Award. With respect to any required tax withholding, unless another arrangement is permitted by the Company in its

9

discretion, the Company shall withhold from the shares of Common Stock issued to you the number of shares necessary to satisfy the Company’s obligation to withhold taxes, that determination to be based on the shares’ Fair Market Value at the time as of which such determination is made. In the event the Company subsequently determines that the aggregate Fair Market Value of any shares of Common Stock withheld as payment of any tax withholding obligation is insufficient to discharge that tax withholding obligation, then you shall pay to the Company, immediately upon the Company’s request, the amount of that deficiency.

15.    Right of the Company and Affiliates to Terminate Your Employment. Nothing contained in this Agreement shall confer upon you the right to continue in the employ of the Company or any Affiliate, or interfere in any way with the rights of the Company or any Affiliate to terminate your employment at any time for any or no reason; provided, however, that any such termination shall be subject to the terms and conditions of any employment agreement between you and the Company or any Affiliate.

16.    No Liability for Good Faith Determinations. Neither the Company nor the members of the Board and the Committee shall be liable for any act, omission or determination taken or made in good faith with respect to this Agreement or the Performance Units granted hereunder.

18.    Company Records. Records of the Company or its Affiliates regarding your period of employment, termination of employment and the reason therefor, leaves of absence, re-employment, and other matters shall be conclusive for all purposes hereunder, unless determined by the Company to be incorrect.

19.    Severability. If any provision of this Agreement is held to be illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining provisions hereof, but such provision shall be fully severable and this Agreement shall be construed and enforced as if the illegal or invalid provision had never been included herein.

20.    Notices. Whenever any notice is required or permitted hereunder, such notice must be in writing and personally delivered or sent by mail. Any such notice required or permitted to be delivered hereunder shall be deemed to be delivered on the date on which it is personally delivered, or, whether actually received or not, on the third business day after it is deposited in the United States mail, certified or registered, postage prepaid, addressed to the person who is to receive it at the address which such person has theretofore specified by written notice delivered in accordance herewith.
