6.2 Exercise Price of an Incentive Stock Option. Subject to the provisions of Section 5.2 regarding Ten Percent Stockholders, the exercise price of each Incentive Stock Option shall be not less than 100% of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.

6.3 Exercise Price of a Nonstatutory Stock Option. The exercise price of each Nonstatutory Stock Option shall be not less than 100% of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted; provided, however, any Nonstatutory Stock Option granted with an exercise price less than 100% of the Fair Market Value of the Common Stock subject to the Option on the date the Option is granted shall satisfy the additional conditions applicable to nonqualified deferred compensation under Section 409A of the Code, in accordance with Section 6.15 and Section 8 hereof. Notwithstanding the foregoing, a Nonstatutory Stock Option may be granted with an exercise price lower than that set forth in the preceding sentence if such Option is granted pursuant to an assumption or substitution for another option in a manner satisfying the provisions of Section 424(a) of the Code.

6.4 Consideration. The exercise price of Common Stock acquired pursuant to an Option shall be paid, to the extent permitted by applicable statutes and regulations, either (a) in cash or by certified or bank check at the time the Option is exercised or (b) in the discretion of the Administrator, upon such terms as the Administrator shall approve, the exercise price may be paid: (i) by delivery to the Company of other Common Stock, duly endorsed for transfer to the Company, with a Fair Market Value on the date of delivery equal to the exercise price (or portion thereof) due for the number of shares being acquired, or by means of attestation whereby the Participant identifies for delivery specific shares of Common Stock that have been held for more than six months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes) that have a Fair Market Value on the date of attestation equal to the exercise price (or portion thereof) and receives a number of shares of Common Stock equal to the difference between the number of shares thereby purchased and the

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

number of identified attestation shares of Common Stock (a “Stock for Stock Exchange”); (ii) during any period for which the Common Stock is publicly traded (i.e., the Common Stock is listed on any established stock exchange or a national market system, including without limitation The NASDAQ Global Market, or if the Common Stock is quoted on the NASDAQ System (but not on The NASDAQ Global Market) or any similar system whereby the Common Stock is regularly quoted by a recognized securities dealer but closing sale prices are not reported), by a copy of instructions to a broker directing such broker to sell the Common Stock for which such Option is exercised, and to remit to the Company the aggregate Exercise Price of such Options (a “Cashless Exercise”); (iii) in any other form of legal consideration that may be acceptable to the Administrator, including without limitation with a full-recourse promissory note; provided, however, if applicable law requires, the par value (if any) of Common Stock, if newly issued, shall be paid in cash or cash equivalents. Any Common Stock acquired upon exercise with a promissory note shall be pledged as security for payment of the principal amount of the promissory note and interest thereon. The interest rate payable under the terms of the promissory note shall not be less than the minimum rate (if any) required to avoid the imputation of additional interest under the Code. Subject to the foregoing, the Administrator (in its sole discretion) shall specify the term, interest rate, amortization requirements (if any) and other provisions of such note. Unless the Administrator determines otherwise, shares of Common Stock having a Fair Market Value at least equal to the principal amount of any such loan shall be pledged by the holder to the Company as security for payment of the unpaid balance of the loan and such pledge shall be evidenced by a pledge agreement, the terms of which shall be determined by the Administrator, in its discretion; provided, however, that each loan shall comply with all applicable laws, regulations and rules of the Board of Governors of the Federal Reserve System and any other governmental agency having jurisdiction. Unless otherwise specifically provided in the Option, the purchase price of Common Stock acquired pursuant to an Option that is paid by delivery (or attestation) to the Company of other Common Stock acquired, directly or indirectly from the Company, shall be paid only by shares of the Common Stock of the Company that have been held for more than six months (or such longer or shorter period of time required to avoid a charge to earnings for financial accounting purposes). Notwithstanding the foregoing, during any period for which the Common Stock is publicly traded (i.e., the Common Stock is listed on any established stock exchange or a national market system, including without limitation The NASDAQ Global Market, or if the Common Stock is quoted on the NASDAQ System (but not on The NASDAQ Global Market) or any similar system whereby the Common Stock is regularly quoted by a recognized securities dealer but closing sale prices are not reported), an exercise with a promissory note or other transaction by a Director or executive officer that involves or may involve a direct or indirect extension of credit or arrangement of an extension of credit by the Company, or an Affiliate in violation of Section 402(a) of the Sarbanes-Oxley Act (codified as Section 13(k) of the Exchange Act) shall be prohibited with respect to any Award under this Plan. Unless otherwise provided in the terms of an Option Agreement, payment of the exercise price by a Participant who is an officer, director or other “insider” subject to Section 16(b) of the Exchange Act in the form of a Stock for Stock Exchange is subject to pre-approval by the Administrator, in its sole discretion. Any such pre-approval shall be documented in a manner that complies with the specificity requirements of Rule 16b-3, including the name of the Participant involved in the transaction, the nature of the transaction, the number of shares to be acquired or disposed of by the Participant and the material terms of the Options involved in the transaction.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

6.5 Transferability of an Incentive Stock Option. An Incentive Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

6.6 Transferability of a Nonstatutory Stock Option. A Nonstatutory Stock Option may, in the sole discretion of the Administrator, be transferable to a Permitted Transferee upon written approval by the Administrator to the extent provided in the Option Agreement. A Permitted Transferee includes: (a) a transfer by gift or domestic relations order to a member of the Optionholder’s immediate family (child, stepchild, grandchild, parent, stepparent, grandparent, spouse, former spouse, sibling, niece, nephew, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, including adoptive relationships), any person sharing the Optionholder’s household (other than a tenant or employee), a trust in which these persons have more than 50% of the beneficial interest, a foundation in which these persons (or the Optionholder) control the management of assets, and any other entity in which these persons (or the Optionholder) own more than 50% of the voting interests; (b) third parties designated by the Administrator in connection with a program established and approved by the Administrator pursuant to which Participants may receive a cash payment or other consideration in consideration for the transfer of such Nonstatutory Stock Option; and (c) such other transferees as may be permitted by the Administrator in its sole discretion. If the Nonstatutory Stock Option does not provide for transferability, then the Nonstatutory Stock Option shall not be transferable except by will or by the laws of descent and distribution and shall be exercisable during the lifetime of the Optionholder only by the Optionholder. Notwithstanding the foregoing, the Optionholder may, by delivering written notice to the Company, in a form satisfactory to the Company, designate a third party who, in the event of the death of the Optionholder, shall thereafter be entitled to exercise the Option.

6.7 Vesting Generally. The Option may, but need not, vest and therefore become exercisable in periodic installments that may, but need not, be equal. The Option may be subject to such other terms and conditions on the time or times when it may be exercised (which may be based on performance or other criteria) as the Administrator may deem appropriate. The vesting provisions of individual Options may vary. No Option may be exercised for a fraction of a share of Common Stock. The Administrator may, but shall not be required to, provide for an acceleration of vesting and exercisability in the terms of any Option Agreement upon the occurrence of a specified event. Unless otherwise specified in the terms of any Option Agreement, each Option granted pursuant to the terms of the Plan shall become exercisable at a rate of 20% per year over the five year period commencing on the date the Option is granted.

6.8 Termination of Continuous Service. Unless otherwise provided in an Option Agreement or in an employment agreement the terms of which have been approved by the Administrator, in the event an Optionholder’s Continuous Service terminates (other than upon the Optionholder’s death or Disability or termination by the Company for Cause), the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination) but only within such period of time ending on the earlier of (a) the date three months following the termination of the Optionholder’s

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

Continuous Service, or (b) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified in the Option Agreement, the Option shall terminate. Unless otherwise provided in an Option Agreement or in an employment agreement the terms of which have been approved by the Administrator, or as otherwise provided in Sections 6.10 and 6.11 of this Plan, outstanding Options that are not exercisable at the time an Optionholder’s Continuous Service terminates for any reason other than for Cause (including an Optionholder’s death or Disability) shall be forfeited and expire at the close of business on the date of such termination. If the Optionholder’s Continuous Service terminates for Cause, all outstanding Options shall be forfeited (whether or not vested) and expire as of the beginning of business on the date of such termination for Cause.

6.9 Extension of Termination Date. An Optionholder’s Option Agreement may also provide that if the exercise of the Option following the termination of the Optionholder’s Continuous Service for any reason other than Cause (other than upon the Optionholder’s death or Disability) would be prohibited at any time because the issuance of shares of Common Stock would violate the registration requirements under the Securities Act or any other state or federal securities law or the rules of any securities exchange or interdealer quotation system, then the Option shall terminate on the earlier of (a) the expiration of the term of the Option in accordance with Section 6.1 or (b) the expiration of a period after termination of the Participant’s Continuous Service that is three months after the end of the period during which the exercise of the Option would be in violation of such registration or other securities law requirements.

6.10 Disability of Optionholder. Unless otherwise provided in an Option Agreement, in the event that an Optionholder’s Continuous Service terminates as a result of the Optionholder’s Disability, the Optionholder may exercise his or her Option (to the extent that the Optionholder was entitled to exercise such Option as of the date of termination), but only within such period of time ending on the earlier of (a) the date 12 months following such termination or (b) the expiration of the term of the Option as set forth in the Option Agreement. If, after termination, the Optionholder does not exercise his or her Option within the time specified herein, the Option shall terminate.

6.11 Death of Optionholder. Unless otherwise provided in an Option Agreement, in the event an Optionholder’s Continuous Service terminates as a result of the Optionholder’s death, then the Option may be exercised (to the extent the Optionholder was entitled to exercise such Option as of the date of death) by the Optionholder’s estate, by a person who acquired the right to exercise the Option by bequest or inheritance or by a person designated to exercise the Option upon the Optionholder’s death, but only within the period ending on the earlier of (a) the date 12 months following the date of death or (b) the expiration of the term of such Option as set forth in the Option Agreement. If, after death, the Option is not exercised within the time specified herein, the Option shall terminate.

6.12 Incentive Stock Option $100,000 Limitation. To the extent that the aggregate Fair Market Value (determined at the time of grant) of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any Optionholder during any calendar year (under all plans of the Company and its Affiliates) exceeds $100,000, the Options or portions thereof which exceed such limit (according to the order in which they were granted) shall be treated as Nonstatutory Stock Options.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

6.13 Early Exercise. The Option may, but need not, include a provision whereby the Optionholder may elect at any time before the Optionholder’s Continuous Service terminates to exercise the Option as to any part or all of the shares of Common Stock subject to the Option prior to the full vesting of the Option. In such case, the shares of Common Stock acquired on exercise shall be subject to the vesting schedule that otherwise would apply to determine the exercisability of the Option. Any unvested shares of Common Stock so purchased may be subject to any other restriction the Administrator determines to be appropriate.

6.14 Reload Options. At the discretion of the Administrator, the Option may include a “reload” feature pursuant to which an Optionholder exercising an option by the delivery of a number of shares of Common Stock in accordance with Section 6.4(b)(i) hereof would automatically be granted an additional Option (with an exercise price equal to the Fair Market Value of the Common Stock on the date the additional Option is granted and with the same expiration date as the original Option being exercised, and with such other terms as the Administrator may provide) to purchase that number of shares of Common Stock equal to the number delivered in a Stock for Stock Exchange of the original Option.

6.15 Additional Requirements Under Section 409A. Each Option Agreement shall include a provision whereby, notwithstanding any provision of the Plan or the Option Agreement to the contrary, the Option shall satisfy the additional conditions applicable to nonqualified deferred compensation under Section 409A of the Code, in accordance with Section 8 hereof, in the event any Option under this Plan is granted with an exercise price less than Fair Market Value of the Common Stock subject to the Option on the date the Option is granted (regardless of whether or not such exercise price is intentionally or unintentionally priced at less than Fair Market Value, or is materially modified at a time when the Fair Market Value exceeds the exercise price), or is otherwise determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code.

7. Provisions of Awards Other Than Options.

7.1 Restricted Awards. A Restricted Award is an Award of actual shares of Common Stock (“Restricted Stock”) or hypothetical Common Stock units (“Restricted Stock Units”) having a value equal to the Fair Market Value of an identical number of shares of Common Stock, which may, but need not, provide that such Restricted Award may not be sold, assigned, transferred or otherwise disposed of, pledged or hypothecated as collateral for a loan or as security for the performance of any obligation or for any other purpose for such period (the “Restricted Period”) as the Administrator shall determine. Each Restricted Award shall be in such form and shall contain such terms, conditions and Restricted Periods as the Administrator shall deem appropriate, including the treatment of dividends or dividend equivalents, as the case may be. The Administrator in its discretion may provide for an acceleration of the end of the Restricted Period in the terms of any Restricted Award, at any time, including in the event a Change in Control occurs. The terms and conditions of the Restricted Award may change from time to time, and the terms and conditions of separate Restricted Awards need not be identical,

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

but each Restricted Award shall include (through incorporation of provisions hereof by reference in the agreement or otherwise) the substance of each of the following provisions:

(a) Purchase Price. The purchase price of Restricted Awards, if any, shall be determined by the Administrator, and may be stated as cash, property or prior services.

(b) Consideration. The consideration for Common Stock acquired pursuant to the Restricted Award shall be paid either: (i) in cash at the time of purchase; or (ii) in any other form of legal consideration that may be acceptable to the Administrator in its discretion including, without limitation, a recourse promissory note, property or a Stock for Stock Exchange, or prior services that the Administrator determines have a value at least equal to the Fair Market Value of such Common Stock.

(c) Vesting. Shares of Common Stock acquired under the Restricted Award may, but need not, be subject to a Restricted Period that specifies a Right of Repurchase in favor of the Company in accordance with a vesting schedule to be determined by the Administrator, or forfeiture in the event the consideration was in the form of services. The Administrator in its discretion may provide for an acceleration of vesting in the terms of any Restricted Award, at any time, including in the event a Change in Control occurs.

(d) Termination of Participant’s Continuous Service. Unless otherwise provided in a Restricted Award or in an employment agreement the terms of which have been approved by the Administrator, in the event a Participant’s Continuous Service terminates for any reason, the Company may exercise its Right of Repurchase or otherwise reacquire, or the Participant shall forfeit the unvested portion of a Restricted Award acquired in consideration of prior or future services, and any or all of the shares of Common Stock held by the Participant which have not vested as of the date of termination under the terms of the Restricted Award shall be forfeited and the Participant shall have no rights with respect to the Award.

(e) Transferability. Rights to acquire shares of Common Stock under the Restricted Award shall be transferable by the Participant only upon such terms and conditions as are set forth in the Award Agreement, as the Administrator shall determine in its discretion, so long as Common Stock awarded under the Restricted Award remains subject to the terms of the Award Agreement.

(f) Concurrent Tax Payment. The Administrator, in its sole discretion, may (but shall not be required to) provide for payment of a concurrent cash award in an amount equal, in whole or in part, to the estimated after tax amount required to satisfy applicable federal, state or local tax withholding obligations arising from the receipt and deemed vesting of restricted stock for which an election under Section 83(b) of the Code may be required.

(g) Lapse of Restrictions. Upon the expiration or termination of the Restricted Period and the satisfaction of any other conditions prescribed by the Administrator, the restrictions applicable to the Restricted Award shall lapse and a stock certificate for the number of shares of Common Stock with respect to which the restrictions have lapsed shall be delivered, free of any restrictions except those that may be imposed by law, the terms of the Plan or the terms of a Restricted Award, to the Participant or the Participant’s beneficiary or estate, as

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

the case may be, unless such Restricted Award is subject to a deferral condition that complies with the 409A Award requirements that may be allowed or required by the Administrator in its sole discretion. The Company shall not be required to deliver any fractional share of Common Stock but will pay, in lieu thereof, the Fair Market Value of such fractional share in cash to the Participant or the Participant’s beneficiary or estate, as the case may be. Unless otherwise subject to a deferral condition that complies with the 409A Award requirements, the Common Stock certificate shall be issued and delivered and the Participant shall be entitled to the beneficial ownership rights of such Common Stock not later than (i) the date that is 2-1/2 months after the end of the Participant’s taxable year for which the Restricted Period ends and the Participant has a legally binding right to such amounts; (ii) the date that is 2-1/2 months after the end of the Company’s taxable year for which the Restricted Period ends and the Participant has a legally binding right to such amounts, whichever is later; or (iii) such earlier date as may be necessary to avoid application of Code Section 409A to such Award.

7.2 Performance Awards.

(a) Nature of Performance Awards. A Performance Award is an Award entitling the recipient to acquire shares of Common Stock or hypothetical Common Stock units having a value equal to the Fair Market Value of an identical number of shares of Common Stock that will be settled in the form of shares of Common Stock upon the attainment of specified performance goals. The Administrator may make Performance Awards independent of or in connection with the granting of any other Award under the Plan. Performance Awards may be granted under the Plan to any Participant, including those who qualify for awards under other performance plans of the Company. The Administrator in its sole discretion shall determine whether and to whom Performance Awards shall be made, the performance goals applicable under each Award, the periods during which performance is to be measured, and all other limitations and conditions applicable to the awarded shares; provided, however, that the Administrator may rely on the performance goals and other standards applicable to other performance plans of the Company in setting the standards for Performance Awards under the Plan. Performance goals shall be based on a pre-established objective formula or standard that specifies the manner of determining the number of shares under the Performance Award that will be granted or will vest if the performance goal is attained. Performance goals will be determined by the Administrator prior to the time 25% of the service period has elapsed and may be based on one or more business criteria that apply to a Participant, a business unit or the Company and its Affiliates. Such business criteria may include, by way of example and without limitation, revenue, earnings before interest, taxes, depreciation and amortization (EBITDA), funds from operations, funds from operations per share, operating income, pre-tax or after-tax income, cash available for distribution, cash available for distribution per share, net earnings, earnings per share, return on equity, return on assets, return on capital, economic value added, share price performance, improvements in the Company’s attainment of expense levels, and implementing or completion of critical projects, or improvement in cash-flow (before or after tax). A performance goal may be measured over a performance period on a periodic, annual, cumulative or average basis and may be established on a corporate-wide basis or established with respect to one or more operating units, divisions, subsidiaries, acquired businesses, minority investments, partnerships or joint ventures. More than one performance goal may be incorporated in a performance objective, in which case achievement with respect to each performance goal may be assessed individually or in combination with each other. The Administrator may, in connection

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

with the establishment of performance goals for a performance period, establish a matrix setting forth the relationship between performance on two or more performance goals and the amount of the Performance Award payable for that performance period. The level or levels of performance specified with respect to a performance goal may be established in absolute terms, as objectives relative to performance in prior periods, as an objective compared to the performance of one or more comparable companies or an index covering multiple companies, or otherwise as the Administrator may determine. Performance goals shall be objective and, if the Company is publicly traded, shall otherwise meet the requirements of Section 162(m) of the Code. Performance goals may differ for Performance Awards granted to any one Participant or to different Participants. A Performance Award to a Participant who is a Covered Employee shall (unless the Administrator determines otherwise) provide that in the event of the Participant’s termination of Continuous Service prior to the end of the performance period for any reason, such Award will be payable only (i) if the applicable performance objectives are achieved and (ii) to the extent, if any, the Administrator shall determine. Such objective performance goals are not required to be based on increases in specific business criteria, but may be based on maintaining the status quo or limiting economic losses.

(b) Restrictions on Transfer. Performance Awards and all rights with respect to such Performance Awards may not be sold, assigned, transferred, pledged or otherwise encumbered.

(c) Rights as a Stockholder. A Participant receiving a Performance Award that is denominated in shares of Common Stock or hypothetical Common Stock units shall have the rights of a stockholder only as to shares actually received by the Participant under the Plan and not with respect to shares subject to the Award but not actually received by the Participant. A Participant shall be entitled to receive a stock certificate evidencing the acquisition of shares of Common Stock under a Performance Award only upon satisfaction of all conditions specified in the written instrument evidencing the Performance Award (or in a performance plan adopted by the Administrator). The Common Stock certificate shall be issued and delivered and the Participant shall be entitled to the beneficial ownership rights of such Common Stock not later than (i) the date that is 2-1/2 months after the end of the Participant’s taxable year for which the Administrator certifies that the Performance Award conditions have been satisfied and the Participant has a legally binding right to such amounts; (ii) the date that is 2-1/2 months after the end of the Company’s taxable year for which the Administrator certifies that the Performance Award conditions have been satisfied and the Participant has a legally binding right to such amounts, whichever is later; or (iii) such other date as may be necessary to avoid application of Section 409A to such Awards.

(d) Termination. Except as may otherwise be provided by the Administrator at any time, a Participant’s rights in all Performance Awards shall automatically terminate upon the Participant’s termination of employment (or business relationship) with the Company and its Affiliates for any reason.

(e) Acceleration, Waiver, Etc. At any time prior to the Participant’s termination of employment (or other business relationship) by the Company and its Affiliates, the Administrator may in its sole discretion accelerate, waive or, subject to Section 13, amend any or all of the goals, restrictions or conditions imposed under any Performance Award. The Administrator in its discretion may provide for an acceleration of vesting in the terms of any Performance Award at any time, including in the event a Change in Control occurs.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

(f) Certification. Following the completion of each performance period, the Administrator shall certify in writing, in accordance with the requirements of Section 162(m) of the Code, whether the performance objectives and other material terms of a Performance Award have been achieved or met. Unless the Administrator determines otherwise, Performance Awards shall not be settled until the Administrator has made the certification specified under this Section 7.2(f).

7.3 Stock Appreciation Rights.

(a) General. Stock Appreciation Rights may be granted either alone (“Free Standing Rights”) or, provided the requirements of Section 7.3(b) are satisfied, in tandem with all or part of any Option granted under the Plan (“Related Rights”). In the case of a Nonstatutory Stock Option, Related Rights may be granted either at or after the time of the grant of such Option. In the case of an Incentive Stock Option, Related Rights may be granted only at the time of the grant of the Incentive Stock Option.

(b) Grant Requirements. A Stock Appreciation Right may only be granted if the Stock Appreciation Right: (i) does not provide for the deferral of compensation within the meaning of Section 409A of the Code; or (ii) satisfies the requirements of Section 7.3(h) and Section 8 hereof. A Stock Appreciation Right does not provide for a deferral of compensation if: (A) the value of the Common Stock the excess over which the right provides for payment upon exercise (the “SAR exercise price”) may never be less than the Fair Market Value of the underlying Common Stock on the date the right is granted, (B) the compensation payable under the Stock Appreciation Right can never be greater than the difference between the SAR exercise price and the Fair Market Value of the Common Stock on the date the Stock Appreciation Right is exercised, (C) the number of shares of Common Stock subject to the Stock Appreciation Right must be fixed on the date of grant of the Stock Appreciation Right, and (D) the right does not include any feature for the deferral of compensation other than the deferral of recognition of income until the exercise of the right.

(c) Exercise and Payment. Upon exercise thereof, the holder of a Stock Appreciation Right shall be entitled to receive from the Company, an amount equal to the product of (i) the excess of the Fair Market Value, on the date of such written request, of one share of Common Stock over the SAR exercise price per share specified in such Stock Appreciation Right or its related Option, multiplied by (ii) the number of shares for which such Stock Appreciation Right shall be exercised. Payment with respect to the exercise of a Stock Appreciation Right that satisfies the requirements of Section 7.3(b)(i) shall be paid on the date of exercise and made in shares of Common Stock (with or without restrictions as to substantial risk of forfeiture and transferability, as determined by the Administrator in its sole discretion), valued at Fair Market Value on the date of exercise. Payment with respect to the exercise of a Stock Appreciation Right that does not satisfy the requirements of Section 7.3(b)(i) shall be paid at the time specified in the Award in accordance with the provisions of Section 7.3(h) and Section 8. Payment may be made in the form of shares of Common Stock (with or without restrictions as to substantial risk of forfeiture and transferability, as determined by the Administrator in its sole discretion), cash or a combination thereof, as determined by the Administrator.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

(d) Exercise Price. The exercise price of a Free Standing Stock Appreciation Right shall be determined by the Administrator, but shall not be less than 100% of the Fair Market Value of one share of Common Stock on the Date of Grant of such Stock Appreciation Right. A Related Right granted simultaneously with or subsequent to the grant of an Option and in conjunction therewith or in the alternative thereto shall have the same exercise price as the related Option, shall be transferable only upon the same terms and conditions as the related Option, and shall be exercisable only to the same extent as the related Option; provided, however, that a Stock Appreciation Right, by its terms, shall be exercisable only when the Fair Market Value per share of Common Stock subject to the Stock Appreciation Right and related Option exceeds the exercise price per share thereof and no Stock Appreciation Rights may be granted in tandem with an Option unless the Administrator determines that the requirements of Section 7.3(b)(i) are satisfied.

(e) Reduction in the Underlying Option Shares. Upon any exercise of a Stock Appreciation Right, the number of shares of Common Stock for which any related Option shall be exercisable shall be reduced by the number of shares for which the Stock Appreciation Right shall have been exercised. The number of shares of Common Stock for which a Stock Appreciation Right shall be exercisable shall be reduced upon any exercise of any related Option by the number of shares of Common Stock for which such Option shall have been exercised.

(f) Written Request. Unless otherwise determined by the Administrator in its sole discretion and only if permitted in the Stock Appreciation Right’s Award Agreement, any exercise of a Stock Appreciation Right for cash, may be made only by a written request filed with the Corporate Secretary of the Company during the period beginning on the third business day following the date of release for publication by the Company of quarterly or annual summary statements of earnings and ending on the twelfth business day following such date. Within 30 days of the receipt by the Company of a written request to receive cash in full or partial settlement of a Stock Appreciation Right or to exercise such Stock Appreciation Right for cash, the Administrator shall, in its sole discretion, either consent to or disapprove, in whole or in part, such written request. A written request to receive cash in full or partial settlement of a Stock Appreciation Right or to exercise a Stock Appreciation Right for cash may provide that, in the event the Administrator shall disapprove such written request, such written request shall be deemed to be an exercise of such Stock Appreciation Right for shares of Common Stock.

(g) Disapproval by Administrator. If the Administrator disapproves in whole or in part any election by a Participant to receive cash in full or partial settlement of a Stock Appreciation Right or to exercise such Stock Appreciation Right for cash, such disapproval shall not affect such Participant’s right to exercise such Stock Appreciation Right at a later date, to the extent that such Stock Appreciation Right shall be otherwise exercisable, or to elect the form of payment at a later date, provided that an election to receive cash upon such later exercise shall be subject to the approval of the Administrator. Additionally, such disapproval shall not affect such Participant’s right to exercise any related Option.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

(h) Additional Requirements under Section 409A. A Stock Appreciation Right that is not intended to or fails to satisfy the requirements of Section 7.3(b)(i) shall satisfy the requirements of this Section 7.3(h) and the additional conditions applicable to nonqualified deferred compensation under Section 409A of the Code, in accordance with Section 8 hereof. The requirements herein shall apply in the event any Stock Appreciation Right under this Plan is granted with an SAR exercise price less than Fair Market Value of the Common Stock underlying the Award on the date the Stock Appreciation Right is granted (regardless of whether or not such SAR exercise price is intentionally or unintentionally priced at less than Fair Market Value, or is materially modified at a time when the Fair Market Value exceeds the SAR exercise price), provides that it is settled in cash, or is otherwise determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A of the Code. Any such Stock Appreciation Right may provide that it is exercisable at any time permitted under the governing written instrument, but such exercise shall be limited to fixing the measurement of the amount, if any, by which the Fair Market Value of a share of Common Stock on the date of exercise exceeds the SAR exercise price (the “SAR Amount”). However, once the Stock Appreciation Right is exercised, the SAR Amount may only be paid on the fixed time, payment schedule or other event specified in the governing written instrument or in Section 8.1 hereof.

8. Additional Conditions Applicable to Nonqualified Deferred Compensation Under Section 409A of the Code.

In the event any Award under this Plan is granted with an exercise price less than Fair Market Value of the Common Stock subject to the Award on the Date of Grant (regardless of whether or not such exercise price is intentionally or unintentionally priced at less than Fair Market Value, or such Award is materially modified and deemed a new Award at a time when the Fair Market Value exceeds the exercise price), or is otherwise determined to constitute a 409A Award, the following additional conditions shall apply and shall supersede any contrary provisions of this Plan or the terms of any 409A Award agreement.

(f) Change in Control Event. The occurrence of a Change in Control Event (within the meaning of Section 8.4(a) hereof), including the Company’s discretionary exercise of the right to accelerate vesting of such Award upon a Change in Control Event or to terminate the Plan or any 409A Award granted hereunder within 12 months of the Change in Control Event.

8.2 Term. Notwithstanding anything to the contrary in this Plan or the terms of any 409A Award agreement, the term of any 409A Award shall expire and such Award shall no longer be exercisable on the date that is the later of: (a) 2¹/2 months after the end of the Company’s taxable year in which the 409A Award first becomes exercisable or distributable pursuant to Section 8 hereof and is not subject to a substantial risk of forfeiture; or (b) 2¹/2 months after the end of the 409A Award recipient’s taxable year in which the 409A Award first becomes exercisable or distributable pursuant to Section 8 hereof and is not subject to a substantial risk of forfeiture, but not later than the earlier of (i) the expiration of 10 years from the date the 409A Award was granted, or (ii) the term specified in the 409A Award agreement.

8.3 No Acceleration. A 409A Award may not be accelerated or exercised prior to the time specified in Section 8 hereof, except in the case of one of the following events:

(a) Domestic Relations Order. The 409A Award may permit the acceleration of the exercise or distribution time or schedule to an individual other than the Participant as may be necessary to comply with the terms of a domestic relations order (as defined in Section 414(p)(1)(B) of the Code).

(b) Conflicts of Interest. The 409A Award may permit the acceleration of the exercise or distribution time or schedule as may be necessary to comply with the terms of a certificate of divestiture (as defined in Section 1043(b)(2) of the Code).

(c) Change in Control Event. The Administrator may exercise the discretionary right to accelerate the vesting of such 409A Award upon a Change in Control Event or to terminate the Plan or any 409A Award granted thereunder within 12 months of the Change in Control Event and cancel the 409A Award for compensation. In addition, the Administrator may exercise the discretionary right to accelerate the vesting of such 409A Award provided that such acceleration does not change the time or schedule of payment of such Award and otherwise satisfies the requirements of this Section 8 and the requirements of Section 409A of the Code.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

9. Covenants of the Company.

9.1 Availability of Shares. During the terms of the Awards, the Company shall keep available at all times the number of shares of Common Stock required to satisfy such Awards.

9.2 Securities Law Compliance. Each Award Agreement shall provide that no shares of Common Stock shall be purchased or sold thereunder unless and until (a) any then applicable requirements of state or federal laws and regulatory agencies shall have been fully complied with to the satisfaction of the Company and its counsel and (b) if required to do so by the Company, the Participant shall have executed and delivered to the Company a letter of investment intent in such form and containing such provisions as the Administrator may require. The Company shall use reasonable efforts to seek to obtain from each regulatory commission or

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

agency having jurisdiction over the Plan such authority as may be required to grant Awards and to issue and sell shares of Common Stock upon exercise of the Awards; provided, however, that this undertaking shall not require the Company to register under the Securities Act the Plan, any Award or any Common Stock issued or issuable pursuant to any such Award. If, after reasonable efforts, the Company is unable to obtain from any such regulatory commission or agency the authority which counsel for the Company deems necessary for the lawful issuance and sale of Common Stock under the Plan, the Company shall be relieved from any liability for failure to issue and sell Common Stock upon exercise of such Awards unless and until such authority is obtained.

10. Use of Proceeds from Stock.

Proceeds from the sale of Common Stock pursuant to Awards shall constitute general funds of the Company.

11. Miscellaneous.

11.1 Acceleration of Exercisability and Vesting. The Administrator shall have the power to accelerate the time at which an Award may first be exercised or the time during which an Award or any part thereof will vest in accordance with the Plan, notwithstanding the provisions in the Award stating the time at which it may first be exercised or the time during which it will vest.

11.2 Stockholder Rights. No Participant shall be deemed to be the holder of, or to have any of the rights of a holder with respect to, any shares of Common Stock subject to such Award unless and until such Participant has satisfied all requirements for exercise of the Award pursuant to its terms and no adjustment shall be made for dividends (ordinary or extraordinary, whether in cash, securities or other property) or distributions of other rights for which the record date is prior to the date such Common Stock certificate is issued, except as provided in Section 12.1 hereof.

11.3 No Employment or Other Service Rights. Nothing in the Plan or any instrument executed or Award granted pursuant thereto shall confer upon any Participant any right to continue to serve the Company or an Affiliate in the capacity in effect at the time the Award was granted or shall affect the right of the Company or an Affiliate to terminate (a) the employment of an Employee with or without notice and with or without Cause, (b) the service of a Consultant pursuant to the terms of such Consultant’s agreement with the Company or an Affiliate or (c) the service of a Director pursuant to the Bylaws of the Company or an Affiliate, and any applicable provisions of the corporate law of the state in which the Company or the Affiliate is incorporated, as the case may be.

11.4 Transfer, Approved Leave of Absence. For purposes of the Plan, no termination of employment by an Employee shall be deemed to result from either (a) a transfer to the employment of the Company from an Affiliate or from the Company to an Affiliate, or from one Affiliate to another; or (b) an approved leave of absence for military service or sickness, or for any other purpose approved by the Company, if the Employee’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which the leave of absence was granted or if the Administrator otherwise so provides in writing.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

11.5 Investment Assurances. The Company may require a Participant, as a condition of exercising or acquiring Common Stock under any Award, (a) to give written assurances satisfactory to the Company as to the Participant’s knowledge and experience in financial and business matters and/or to employ a purchaser representative reasonably satisfactory to the Company who is knowledgeable and experienced in financial and business matters and that he or she is capable of evaluating, alone or together with the purchaser representative, the merits and risks of exercising the Award; and (b) to give written assurances satisfactory to the Company stating that the Participant is acquiring Common Stock subject to the Award for the Participant’s own account and not with any present intention of selling or otherwise distributing the Common Stock. The foregoing requirements, and any assurances given pursuant to such requirements, shall be inoperative if (i) the issuance of the shares of Common Stock upon the exercise or acquisition of Common Stock under the Award has been registered under a then currently effective registration statement under the Securities Act or (ii) as to any particular requirement, a determination is made by counsel for the Company that such requirement need not be met in the circumstances under the then applicable securities laws. The Company may, upon advice of counsel to the Company, place legends on stock certificates issued under the Plan as such counsel deems necessary or appropriate in order to comply with applicable securities laws, including, but not limited to, legends restricting the transfer of the Common Stock.

11.6 Withholding Obligations. To the extent provided by the terms of an Award Agreement and subject to the discretion of the Administrator, the Participant may satisfy any federal, state or local tax withholding obligation relating to the exercise or acquisition of Common Stock under an Award by any of the following means (in addition to the Company’s right to withhold from any compensation paid to the Participant by the Company) or by a combination of such means: (a) tendering a cash payment; (b) authorizing the Company to withhold shares of Common Stock from the shares of Common Stock otherwise issuable to the Participant as a result of the exercise or acquisition of Common Stock under the Award, provided, however, that no shares of Common Stock are withheld with a value exceeding the minimum amount of tax required to be withheld by law; (c) delivering to the Company previously owned and unencumbered shares of Common Stock of the Company or (d) by execution of a recourse promissory note by a Participant who is not a Director or executive officer. Unless otherwise provided in the terms of an Option Agreement, payment of the tax withholding by a Participant who is an officer, director or other “insider” subject to Section 16(b) of the Exchange Act by delivering previously owned and unencumbered shares of Common Stock of the Company or in the form of share withholding is subject to pre-approval by the Administrator, in its sole discretion. Any such pre-approval shall be documented in a manner that complies with the specificity requirements of Rule 16b-3, including the name of the Participant involved in the transaction, the nature of the transaction, the number of shares to be acquired or disposed of by the Participant and the material terms of the Award involved in the transaction.

11.7 Right of Repurchase. Each Award Agreement may provide that, following a termination of the Participant’s Continuous Service, the Company may repurchase the

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

Participant’s unvested Common Stock acquired under the Plan as provided in this Section 11.7 (the “Right of Repurchase”). The Right of Repurchase for unvested Common Stock shall be exercisable at a price equal to the lesser of the purchase price at which such Common Stock was acquired under the Plan or the Fair Market Value of such Common Stock (if an Award is granted solely in consideration of past services without payment of any additional consideration, the unvested Common Stock shall be forfeited without any repurchase). The Award Agreement may specify the period of time following a termination of the Participant’s Continuous Service during which the Right of Repurchase may be exercised.

12. Adjustments Upon Changes in Stock.

12.1 Capitalization Adjustments. If any change is made in the Common Stock subject to the Plan, or subject to any Award, without the receipt of consideration by the Company (through merger, consolidation, reorganization, recapitalization, reincorporation, stock dividend, dividend in property other than cash, stock split, liquidating dividend, combination of shares, exchange of shares, change in corporate structure or other transaction not involving the receipt of consideration by the Company), then (a) the aggregate number of shares of Common Stock or class of shares which may be purchased pursuant to Awards granted hereunder; (b) the aggregate number of shares of Common Stock or class of shares which may be purchased pursuant to Incentive Stock Options granted hereunder; (c) the number and/or class of shares of Common Stock covered by outstanding Options and Awards; (d) the maximum number of shares of Common Stock with respect to which Options may be granted to any single Optionholder during any calendar year; and (e) the exercise price of any Option in effect prior to such change shall be proportionately adjusted by the Administrator to reflect any increase or decrease in the number of issued shares of Common Stock or change in the Fair Market Value of such Common Stock resulting from such transaction; provided, however, that any fractional shares resulting from the adjustment shall be eliminated. The Administrator shall make such adjustments, and its determination shall be final, binding and conclusive. The conversion of any securities of the Company that are by their terms convertible shall not be treated as a transaction “without receipt of consideration” by the Company.

12.2 Dissolution or Liquidation. In the event of a dissolution or liquidation of the Company, then all outstanding Awards shall terminate immediately prior to such event.

12.3 Change in Control – Asset Sale, Merger, Consolidation or Reverse Merger. In the event of a Change in Control, a dissolution or liquidation of the Company, or any corporate separation or division, including, but not limited to, a split-up, a split-off or a spin-off, or a sale, in one or a series of related transactions, of all or substantially all of the assets of the Company; a merger or consolidation in which the Company is not the Surviving Entity; or a reverse merger in which the Company is the Surviving Entity, but the shares of Common Stock outstanding immediately preceding the merger are converted by virtue of the merger into other property, whether in the form of securities, cash or otherwise, then the Company, to the extent permitted by applicable law, but otherwise in the sole discretion of the Administrator may provide for: (a) the continuation of outstanding Awards by the Company (if the Company is the Surviving Entity); (b) the assumption of the Plan and such outstanding Awards by the Surviving Entity or its parent; (c) the substitution by the Surviving Entity or its parent of Awards with substantially the same terms (including an award to acquire the same consideration paid to the

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

stockholders in the transaction described in this Section 12.3) for such outstanding Awards and, if appropriate, subject to the equitable adjustment provisions of Section 12.1 hereof; (d) the cancellation of such outstanding Awards in consideration for a payment (in the form of stock or cash) equal in value to the Fair Market Value of vested Awards, or in the case of an Option, the difference between the Fair Market Value and the exercise price for all shares of Common Stock subject to exercise (i.e., to the extent vested) under any outstanding Option; or (e) the cancellation of such outstanding Awards without payment of any consideration. If such Awards would be canceled without consideration for vested Awards, the Participant shall have the right, exercisable during the later of the 10-day period ending on the fifth day prior to such merger or consolidation or 10 days after the Administrator provides the Award holder a notice of cancellation, to exercise such Awards in whole or in part without regard to any installment exercise provisions in the Option Agreement.

13. Amendment of the Plan and Awards.

13.1 Amendment of Plan. The Board at any time, and from time to time, may amend or terminate the Plan. However, except as provided in Section 12.1 relating to adjustments upon changes in Common Stock, no amendment shall be effective unless approved by the stockholders of the Company to the extent stockholder approval is necessary to satisfy any applicable law or any NASDAQ or securities exchange listing requirements. At the time of such amendment, the Board shall determine, upon advice from counsel, whether such amendment will be contingent on stockholder approval.

13.2 Stockholder Approval. The Board may, in its sole discretion, submit any other amendment to the Plan for stockholder approval, including, but not limited to, amendments to the Plan intended to satisfy the requirements of Section 162(m) of the Code and the regulations thereunder regarding the exclusion of performance-based compensation from the limit on corporate deductibility of compensation paid to certain executive officers.

13.3 Contemplated Amendments. It is expressly contemplated that the Board may amend the Plan in any respect the Board deems necessary or advisable to provide eligible Employees with the maximum benefits provided or to be provided under the provisions of the Code and the regulations promulgated thereunder relating to Incentive Stock Options or to the nonqualified deferred compensation provisions of Section 409A of the Code and/or to bring the Plan and/or Awards granted under it into compliance therewith.

13.4 No Impairment of Rights. Rights under any Award granted before amendment of the Plan shall not be impaired by any amendment of the Plan unless (a) the Company requests the consent of the Participant and (b) the Participant consents in writing. However, a cancellation of an Award where the Participant receives a payment equal in value to the Fair Market Value of the vested Award or, in the case of vested Options, the difference between the Fair Market Value and the exercise price, shall not be an impairment of the Participant’s rights that requires consent of the Participant.

13.5 Amendment of Awards. The Administrator at any time, and from time to time, may amend the terms of any one or more Awards; provided, however, that the Administrator may not effect any amendment which would otherwise constitute an impairment

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

of the rights under any Award unless (a) the Company requests the consent of the Participant and (b) the Participant consents in writing. For the avoidance of doubt, the cancellation of a vested Award where the Participant receives a payment equal in value to the Fair Market Value of the vested Award or, in the case of vested Options, the difference between the Fair Market Value of the Common Stock underlying the Option and the aggregate exercise price, shall not be an impairment of the Participant’s rights that requires consent of the Participant.

14. General Provisions.

14.1 Other Compensation Arrangements. Nothing contained in this Plan shall prevent the Board from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.

14.2 Recapitalizations. Each Award Agreement shall contain provisions required to reflect the provisions of Section 12.1.

14.3 Delivery. Upon exercise of a right granted pursuant to an Award under this Plan, the Company shall issue Common Stock or pay any amounts due within a reasonable period of time thereafter. Subject to any statutory or regulatory obligations the Company may otherwise have, for purposes of this Plan, 30 days shall be considered a reasonable period of time.

14.4 Other Provisions. The Award Agreements authorized under the Plan may contain such other provisions not inconsistent with this Plan, including, without limitation, restrictions upon the exercise of the Awards, as the Administrator may deem advisable.

14.5 Cancellation and Rescission of Awards for Detrimental Activity.

(a) Upon exercise, payment or delivery pursuant to an Award, the Participant shall certify in a manner acceptable to the Company that the Participant has not engaged in any Detrimental Activity described in Section 2.19.

(b) Unless the Award Agreement specifies otherwise, the Administrator may cancel, rescind, suspend, withhold or otherwise limit or restrict any unexpired, unpaid or deferred Awards at any time if the Participant engages in any Detrimental Activity described in Section 2.19.

(c) In the event a Participant engages in Detrimental Activity described in Section 2.19 after any exercise, payment or delivery pursuant to an Award, during any period for which any restrictive covenant prohibiting such activity is applicable to the Participant, such exercise, payment or delivery may be rescinded within one year thereafter. In the event of any such rescission, the Participant shall pay to the Company the amount of any gain realized or payment received as a result of the exercise, payment or delivery, in such manner and on such terms and conditions as may be required by the Company. The Company shall be entitled to set-off against the amount of any such gain any amount owed to the Participant by the Company.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

14.6 Disqualifying Dispositions. Any Participant who shall make a “disposition” (as defined in Section 424 of the Code) of all or any portion of shares of Common Stock acquired upon exercise of an Incentive Stock Option within two years from the Date of Grant of such Incentive Stock Option or within one year after the issuance of the shares of Common Stock acquired upon exercise of such Incentive Stock Option shall be required to immediately advise the Company in writing as to the occurrence of the sale and the price realized upon the sale of such shares of Common Stock.

15. Market Stand-Off.

Each Option Agreement and Award Agreement shall provide that, in connection with any underwritten public offering by the Company of its equity securities pursuant to an effective registration statement filed under the Securities Act, the Participant shall agree not to sell, make any short sale of, loan, hypothecate, pledge, grant any option for the repurchase of, transfer the economic consequences of ownership or otherwise dispose or transfer for value or otherwise agree to engage in any of the foregoing transactions with respect to any Common Stock without the prior written consent of the Company or its underwriters, for such period of time from and after the effective date of such registration statement as may be requested by the Company or such underwriters (the “Market Stand-Off”). In order to enforce the Market Stand-Off, the Company may impose stop-transfer instructions with respect to the shares of Common Stock acquired under this Plan until the end of the applicable stand-off period. If there is any change in the number of outstanding shares of Common Stock by reason of a stock split, reverse stock split, stock dividend, recapitalization, combination, reclassification, dissolution or liquidation of the Company, any corporate separation or division (including, but not limited to, a split-up, a split-off or a spin-off), a merger or consolidation; a reverse merger or similar transaction, then any new, substituted or additional securities which are by reason of such transaction distributed with respect to any shares of Common Stock subject to the Market Stand-Off, or into which such shares of Common Stock thereby become convertible, shall immediately be subject to the Market Stand-Off.

16. Effective Date of Plan.

The Plan shall become effective as of the Effective Date, but no Award may be exercised (or, in the case of a stock Award, may be granted) unless and until the Plan has been approved by the stockholders of the Company, which approval shall be within twelve (12) months before or after the date the Plan is adopted by the Board.

17. Termination or Suspension of the Plan.

The Plan shall terminate automatically on the day before the 10th anniversary of the Effective Date. No Award shall be granted pursuant to the Plan after such date, but Awards theretofore granted may extend beyond that date. The Board may suspend or terminate the Plan at any earlier date pursuant to Section 13.1 hereof. No Awards may be granted under the Plan while the Plan is suspended or after it is terminated.

Diamondback Energy Services, Inc. 2007 Equity Incentive Plan

18. Choice of Law.

The law of the State of Delaware shall govern all questions concerning the construction, validity and interpretation of this Plan, without regard to such state’s conflict of law rules.

19. Execution.

To record the adoption of the Plan by the Board, the Company has caused its authorized officer to execute the Plan as of the date specified below.
