THIS EMPLOYMENT AGREEMENT (the “Agreement”), is made and entered into as of February 9, 2018 (the
“Effective Date”), by and between Alta Mesa Services, LP, a Texas limited partnership (the “Company”), Ronald J. Smith (hereafter “Executive”) and, solely with respect to
Section 41, Alta Mesa Holdings, LP, a Texas limited partnership (“Alta Mesa”). The Company and Executive may sometimes hereafter be referred to singularly as a “Party” or collectively as
the “Parties.” 
 WITNESSETH: 

WHEREAS, Alta Mesa Holdings, L.P. (the “Parent”), has entered into a Contribution Agreement by and among High Mesa
Holdings, LP, High Mesa Holdings GP, LLC, Alta Mesa Holdings GP, LLC, Silver Run and certain other parties thereto, dated as of August 16, 2017, as the same may be amended from time to time, pursuant to which Silver Run will acquire certain of
the outstanding equity interests in Parent (the “Transaction”); and 
 WHEREAS, the Company desires to continue to
secure the employment services of Executive subject to the terms and conditions hereafter set forth; 
 NOW, THEREFORE, in
consideration of Executive’s continued employment with the Company, and the premises and mutual covenants contained herein, the Parties hereto agree as follows: 

1. Employment Position and Defined Terms. During the Employment Period (as defined in Section 4), the Company shall
employ Executive, and Executive shall serve, as a Vice President of the Company. During the Employment Period, Executive shall also serve in the same positions of employment with Silver Run as he does with the Company for no additional compensation.
Executive’s principal place of employment shall be at the main business offices of the Company in Houston, Texas. Defined terms used in the Agreement that are not otherwise defined herein when first used are defined in Sections 6(d)
and 10(d). 
 2. Compensation. 

(a) Base Salary. The Company shall pay to Executive during the Employment Period a base salary of Two Hundred Seventy
Thousand dollars ($270,000) per year, as adjusted pursuant to the subsequent provisions of this paragraph (the “Base Salary”). The Base Salary shall be payable in accordance with the Company’s normal payroll schedule and
procedures for its executives. Nothing contained herein shall preclude the payment of any other compensation to Executive at any time as determined by the Board. 

  

					
		  		  	R. Smith Agreement

 (b) Annual Bonus. 

(1) In addition to the Base Salary in Section 2(a), for each annual fiscal year of the Company during the
Employment Period (each such annual period being referred to as a “Bonus Period”), Executive will be eligible to participate in an annual bonus program established by the Board, under which Executive shall receive a bonus equal to a
percentage of Executive’s Base Salary paid during each such one-year period (referred to herein as the “Annual Bonus”), such percentage to be established by the Board in its sole
discretion; provided, however, that the payment of any Annual Bonus will be subject to the Board’s discretion and made only if Executive has met the pre-established performance criteria set by the Board
for the Bonus Period. 
 (2) In the event that the Employment Period ends before the end of the Bonus Period, Executive shall
be entitled to a pro rata portion of the Annual Bonus for that year (based on the number of days in which Executive was employed during the year divided by 365), as determined based on satisfaction of the performance criteria for that Bonus Period
on a pro rata basis (calculated as if the final day of the Employment Period were the final day of the applicable Bonus Period), unless Executive was terminated for Cause or terminated voluntarily without Good Reason, in any of which events
Executive shall not be entitled to any Annual Bonus for that year. 
 (3) If Executive successfully meets the performance
criteria for a Bonus Period, the Company shall pay Executive the Annual Bonus amount determined by the Board within the earlier of: (A) sixty days (60) days after the end of the Bonus Period or (B) sixty days (60) after the end
of the Employment Period. 
 (c) Compensation in Event of Injury or Sickness. In the event that Executive becomes
injured or suffers a medically determinable physical or mental illness, as determined by a physician acceptable to both the Company and Executive in the same manner as provided in the definition of Disability in
Section 6(d), during the Employment Period, Executive shall be entitled to receive continued Base Salary (as set forth in Section 2(a)) for a period of six (6) months following the occurrence
of such injury or sickness; provided, however, such Base Salary shall be reduced by any short-term and/or long-term disability income benefits that are received by Executive under such programs sponsored by the Company (or an Affiliate) during such 6-month period. 
 3. Duties and Responsibilities of Executive. During the Employment Period, Executive shall
devote his full working time to (a) the business of the Company and its Affiliates and (b) performance of the duties and responsibilities assigned to Executive to the best of Executive’s ability and with reasonable diligence. In
determining Executive’s duties and responsibilities, Executive shall not be assigned duties and responsibilities that are materially inconsistent with Executive’s position. This Section 3 shall not be construed as
preventing Executive from (a) engaging in reasonable volunteer services for charitable, educational or civic organizations, or (b) investing personal assets in such a manner that will not require a material amount of the Executive’s
time or services in the operation of the businesses in which such investments are made; provided, however, no such other activity shall conflict or materially interfere with Executive’s loyalties, duties or responsibilities to the Company and
its Affiliates. Executive shall at all times use his best efforts to comply in good faith with United States laws applicable to Executive’s actions on behalf of the Company and its Affiliates. Executive understands and agrees that Executive may
be required to travel from time to time for purposes of the Company’s business. The Parties agree that Executive’s principal work location cannot be relocated further than 50 miles from Executive’s principal work location on the
Effective Date, except as mutually agreed by the Parties.

 4. Term of Employment. Executive’s term of employment with the Company under this Agreement
shall be for the period from the Effective Date through the date that is two (2) years from the Effective Date, unless earlier terminated in accordance with this Agreement, and if not earlier terminated, this Agreement will expire upon the date
that is two (2) years from the Effective Date. 
 The period from the Effective Date through the earlier of the second (2nd)
anniversary of the Effective Date and the date of Executive’s termination of employment with the Company and its Affiliates for whatever reason (the “Termination Date”) shall be referred to herein as the “Employment
Period.” Notwithstanding the above, Executive agrees to remain available beyond the Employment Period to provide assistance to the Company or its Affiliate in the event that the Company or an Affiliate become involved in litigation (or
another type of dispute or controversy) regarding matters of which Executive has relevant knowledge resulting from Executive’s employment with the Company or an Affiliate. Such post-termination assistance shall be provided by Executive in the
capacity of an independent contractor at an agreed-upon, reasonable consulting fee, and shall not be deemed to create or continue an employee-employer or fiduciary relationship, or to represent a continuation of this Agreement. 

5. Benefits. Subject to the terms and conditions of this Agreement, during the Employment Period, Executive shall be entitled to all of the
following: 
 (a) Reimbursement of Business Expenses. The Company shall pay or reimburse Executive for all
reasonable travel, entertainment and other business expenses paid or incurred by Executive in the performance of duties hereunder. The Company shall also provide Executive with suitable office space, including staff support, paid parking, and
necessary equipment, including but not limited to, cellular telephone and laptop computer. 
 (b) Other Employee
Benefits. Executive shall be entitled to participate in any pension, retirement, 401(k), profit-sharing, and other employee benefits plans or programs of the Company to the same extent as available to other senior management employees of the
Company under the terms of such plans or programs. Executive shall also be entitled to participate in any group insurance, hospitalization, medical, dental, health, life, accident, disability and other employee benefits plans or programs of the
Company to the extent available to other senior management employees of the Company, and their spouses and eligible dependents, under the terms of such plans or programs including any medical expense reimbursement account and post-retirement medical
program as made available to other senior management employees of the Company. 
 (c) Vacation and Holidays. Executive
shall be entitled to five (5) weeks of paid vacation per calendar year (prorated in any calendar year during which Executive is employed for less than the entire year based on the number of days in such calendar year in which Executive was
employed). Executive shall also be entitled to all paid holidays and personal days provided by the Company for its key management employees under the Company’s personnel policy as then effective. Unused vacation shall not carry over to the
following year unless specifically approved by the Company.

 (d) Equity Incentive Awards. Executive shall be eligible to participate in
the Alta Mesa Resources, Inc. 2018 Long Term Incentive Plan (the “LTIP”) or any other incentive plan sponsored by the Company which provides for equity grants of incentive awards. The terms and conditions of any equity incentive
award granted to Executive shall be set forth in the incentive plan document and award agreement governing such award. 
 (e)
Annual Physical. Executive shall be entitled to be reimbursed by the Company for the full cost of an annual physical examination by a physician (1) selected by the Company or (2) selected by Executive and approved by the
Company. 
 (f) Key Man or Company-Owned Life Insurance. The Company may, at any time during the term of this Agreement,
apply for and procure as owner, and for its sole benefit, life insurance on the Executive’s life in such amounts and in such forms as the Company may select. Executive hereby acknowledges that he will have no interest whatsoever in any such
insurance policy. Executive shall submit to such medical examinations, supply such information, and execute such documents as may be reasonably requested by the insurer to obtain any such key man policy. 

(g) Tax Planning, Preparation and Advice. Executive shall be entitled to be reimbursed by the Company for the cost of tax
preparation and planning by a certified financial planner or certified public accountant (1) selected by the Company or (2) selected by Executive and approved by the Company, provided that such annual reimbursement shall not exceed
$5,000.00. 
 6. Rights and Payments upon Termination. The Executive’s right to compensation and benefits for periods after the
Termination Date shall be determined in accordance with this Section 6. Except as otherwise expressly required by law or as specifically provided in an employee benefit plan or this Agreement, all of Executive’s rights
to salary, severance, benefits, bonuses and other compensatory amounts under this Agreement shall cease upon the Termination Date. 

(a) Minimum Payments and Vesting. Executive shall be entitled to the following minimum payments under this
Section 6(a), in addition to any other payments or benefits which Executive is entitled to receive under the terms of any employee benefit plan or program or Section 6(b): 

(1) unpaid salary for the full calendar month in which the Termination Date occurs; provided, however, if Executive is
terminated for Cause or terminates his employment voluntarily without Good Reason, Executive shall only be entitled to receive accrued but unpaid salary through the Termination Date; 

(2) unpaid vacation days for that year which have accrued through the Termination Date; 

  

					
		  	4	  	R. Smith Agreement

 (3) reimbursement of reasonable business expenses that were incurred but unpaid
as of the Termination Date; and 
 (4) to the extent Executive participated in any nonqualified deferred compensation plan or
program with vesting criteria, or received any equity incentive grant that is not fully vested, as of the Termination Date, Executive will automatically vest as of the Termination Date as follows: 

(A) subject to Section 6(c), if Executive is involuntarily terminated by the Company other than for
Cause (and not including death or termination due to Disability), or if the Executive terminates his employment for Good Reason, Executive shall become immediately 100% vested in (i) any outstanding awards of restricted stock, stock options and
any other equity incentive awards granted under the LTIP (or any other equity incentive plan of the Company or Silver Run) that vest solely based on the passage of time (with any such awards that vest based on the attainment of performance-based
vesting conditions vesting at the target level); and (ii) any nonqualified deferred compensation account balance or benefit; and 

(B) if Executive is terminated by the Company for Cause, or voluntarily terminates his employment without Good Reason, all
unvested equity incentive awards shall be treated in accordance with the terms of the outstanding award agreement or plan document, as applicable. 

Salary and accrued vacation days under this Section 6(a) shall be paid to Executive within five (5) business
days following the Termination Date in a cash lump sum payment, less applicable withholdings. Business expenses shall be reimbursed in accordance with the Company’s normal procedures. 

(b) Other Severance Payments. In the event that during the Employment Period (i) Executive’s employment is
involuntarily terminated by the Company (except due to a No Severance Benefits Event), (ii) Executive’s employment is terminated due to death or Disability, or (iii) Executive terminates his employment for Good Reason; then in any such
event under clause (i), (ii), or (iii), subject to Section 6(c), the following severance benefits shall be provided to Executive or, in the event of his death before receiving all such benefits, to Executive’s
Designated Beneficiary following his death: 
 (1) Additional Payment. The Company shall pay additional compensation
as described in this Section 6(b)(1) (the “Additional Payment”). Subject to Section 6(c), the Company shall make the Additional Payment to Executive in a cash lump
sum, net of applicable withholdings. 
 (A) Termination Not Following Change in Control. If the Termination Date does
not occur within the 15-month period immediately following a Change in Control, the Additional Payment shall be (i) an amount equal to Executive’s Base Salary in effect as of the Termination Date,
(ii) an amount equal to the greater of (x) 100% of the “target” bonus for Executive for the year containing 

  

					
		  	5	  	R. Smith Agreement

 
the Termination Date or (y) the amount of the Annual Bonus paid to the Executive for the year immediately preceding the year containing the Termination Date, and (iii) an additional
$20,000.00 lump sum cash payment for outplacement services. In such event, the Additional Payments described in Section 6(b)(1)(C) following a Change in Control shall be inapplicable for Executive. 

(B) Anticipatory Termination. If the Executive incurs an Anticipatory Termination, he shall be entitled to receive, in
addition to the payment described in Section 6(b)(1)(A) above, an additional amount equal to the sum of (i) fifty percent (50%) of Executive’s Base Salary as in effect as of the Termination Date, plus
(ii) fifty percent (50%) times the greater of (x) 100% of the “target” bonus for Executive for the year containing the Termination Date or (y) the amount of the Annual Bonus paid to the Executive for the year immediately
preceding the year containing the Termination Date (the “Anticipatory Termination Payment”). In such event, the Additional Payments described in Section 6(b)(1)(C) following a Change in Control shall be
inapplicable for Executive. The Anticipatory Termination Payment shall be subject to the Executive executing a second release agreement, as described in Section 6(c), but covering only the period from the Termination Date
until the date immediately following the Change in Control. 
 (C) Termination Following Change in Control. If the
Termination Date occurs within the fifteen (15) month period immediately following a Change in Control, the Additional Payment shall be (i) an amount equal to one hundred fifty percent (150%) of Executive’s Base Salary in effect as of
the Termination Date, (ii) an amount equal to one hundred fifty percent (150%) times the greater of (x) 100% of the “target” bonus for Executive for the year containing the Termination Date or (y) the amount of the Annual
Bonus paid to the Executive for the year immediately preceding the year containing the Termination Date, and (iii) an additional $20,000.00 lump sum cash payment for outplacement services. In such event, the Additional Payments described in
Sections 6(b)(1)(A) and 6(b)(1)(B) above shall be inapplicable for Executive. 
 (2)
COBRA Coverage. 
 (A) In the event that Executive timely elects continuation coverage under any of the Company’s
“group health plans” within the meaning of Treasury Regulations Section 54.4980B-2 Q/A-1 (collectively, the “Health Plan”) on behalf of
himself and any of his eligible covered dependents (including his spouse) pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), following the Termination Date, the Company shall pay directly
or reimburse Executive for an amount equal to the monthly premium for such COBRA coverage for each month during which such COBRA coverage is in effect during the period commencing on the Termination Date and ending upon the earliest of (x) the
date that is eighteen (18) months following the Termination Date, (y) the date that Executive and Executive’s covered dependents become no longer eligible for COBRA coverage or (z) the date Executive

  

					
		  	6	  	R. Smith Agreement

 
becomes eligible to receive group healthcare coverage from a subsequent employer (and Executive agrees to promptly notify the Company of such eligibility). In all other respects, Executive and
his dependents shall be treated the same as any other qualified beneficiaries under the Health Plan and COBRA. 
 (B)
Executive and Executive’s spouse, if applicable, consent and agree to acquire and maintain any and all coverage that either or both of them are entitled to at any time during their lives under the Medicare program or any similar program of the
United States or any agency thereof. Executive and Executive’s spouse further agree to pay any required premiums for Medicare coverage from their personal funds. 

(C) Notwithstanding Section 6(b)(2)(A) to the contrary, the Company may alter the manner in which
health benefits are provided to Executive under such section following termination of Executive’s employment to the extent the Company reasonably determines is necessary for purposes of satisfying Code Section 105(h)(2) or avoiding the
imposition of an excise tax on the Company or any of its Affiliates, provided that such alterations do not materially decrease coverage or increase the after-tax cost to Executive of such benefits. 

(3) Code Section 280G Tax Gross-up. If the Termination Date
occurs within two (2) years after the Effective Date, the Accounting Firm shall determine if any of the payments or benefits received or to be received by Executive (including, without limitation, any payment or benefits received in connection
with a Change in Control or Executive’s termination of employment, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement), constitute “parachute payments” within the meaning of Code
Section 280G as a result of a “change in ownership or control,” under and within the meaning of Treasury Regulation Section 1.280G-1, of Silver Run or any of its subsidiaries, including the
Company, but excluding as a result of the closing of the Transaction (all such payments and benefits collectively referred to herein as the “280G Payments”) that are subject to the excise tax imposed under Code Section 4999
(the “Excise Tax”). If the Accounting Firm determines any of the 280G Payments are subject to the Excise Tax, the Company shall pay to Executive, as soon as reasonably practicable following such determination but in any event no
later than the end of the year following the year in which the Executive pays the relevant taxes, an additional amount equal to the sum of the Excise Tax payable by Executive plus the amount that the Accounting Firm determines is necessary to put
Executive in the same after-tax position (taking into account all applicable federal, state and local excise, income and other taxes) as if no Excise Tax had been imposed. 

All determinations required to be made under this Section 6(b)(3), including whether a payment would result in an
“excess parachute payment” within the meaning of Code Section 280G and the assumptions utilized in arriving at such determination, shall be made by the Accounting Firm. All fees and expenses of the Accounting Firm shall be paid solely
by the Company. The final determination by the Accounting Firm shall be binding on the Parties absent manifest error. 

  

					
		  	7	  	R. Smith Agreement

 Executive agrees to reasonably cooperate with the Company to minimize the amount of any excess
parachute payments, including, without limitation, assisting the Company in establishing that some or all of the payments received by Executive which are “contingent on a change”, as described in Code Section 280G(b)(2)(A), are
reasonable compensation for personal services actually rendered by Executive before the date of such change or to be rendered by Executive on or after the date of such change. Notwithstanding the foregoing, Executive shall not be required to take
any action which his attorney or tax advisor advises him in writing exposes the Executive to material personal liability. 

(4) Other Termination of Employment. For purposes of clarity, in the event that (i) Executive voluntarily resigns
or otherwise voluntarily terminates employment, except due to death, Disability or for Good Reason, or (ii) Executive’s employment is terminated due to a No Severance Benefits Event then, in any such event under clause (i) or (ii),
the Company shall have no obligation to provide the severance benefits described in paragraphs (1), (2) and (3) (above) of this Section 6(b), except to offer COBRA coverage (as required by COBRA law) but not at the rate
described in paragraph (2). However, Executive shall still be entitled to the minimum benefits provided under Section 6(a). 

(5) No Duplication of Severance Benefits. The severance payments provided under Section 6(b)
shall supersede and replace any severance payments under any severance pay plan or similar agreement that the Company or any Affiliate maintains for key management employees or employees generally. 

(c) Release Agreement. Notwithstanding any provision of the Agreement to the contrary, in order to receive the vesting
acceleration provided under Section 6(a)(4)(A) or the severance benefits provided under Section 6(b)(1), (2), or (3), the Executive must first execute an appropriate release agreement
(on a form provided by the Company) whereby the Executive agrees to release and waive, in return for such vesting acceleration or severance benefits, any claims that Executive may have against the Company or any of its Affiliates including, without
limitation, for unlawful discrimination (e.g., Title VII of the Civil Rights Act); provided, however, such release agreement shall not release any claim or cause of action by or on behalf of the Executive for (a) any payment or benefit
that may be due or payable under this Agreement or any vested benefits under any employee benefit plan or program or (b) non-payment of salary or benefits to which Executive is entitled from the Company
as of the Termination Date. The release agreement must be provided to Executive within five (5) days following the Termination Date, and signed by Executive and returned to the Company, and any applicable revocation period must have expired, no
later than sixty (60) days following the Termination Date; provided, however, the second release agreement required for an Anticipatory Termination Payment under Section 6(b)(1)(B) must be provided to Executive within
five (5) days following the Change in Control Date, and signed by Executive and returned to the Company, and any applicable revocation period must have expired, no later than sixty (60) days following the Change in Control Date. Any
payments to which Executive becomes entitled pursuant to Section 6(b)(1), shall be paid within ten (10) days after the executed release agreement (or executed second release agreement with respect to an Anticipatory
Termination Payment) has been timely returned to the Company for counter-signature and become effective and non-revocable by 

  

					
		  	8	  	R. Smith Agreement

 
Executive under the terms of the release agreement. Notwithstanding anything in this Agreement to the contrary, to the extent that any severance payments or benefits provided under
Section 6(a)(4)(A) or Section 6(b) are deferred compensation under Code Section 409A, and are not otherwise exempt from the application of Section 409A, then, if the period during which
Executive may consider and sign the release agreement spans two calendar years, the severance payments or benefits will not be made or begin until the later calendar year. 

(d) Definitions. 

(1) “Accounting Firm” means any nationally recognized, certified public accounting firm selected by the
Company and reasonably acceptable to the Executive; provided, however, the firm selected must be within the top 20 in the United States at such time based on annual revenues for certified public accounting firms in the immediately preceding year.

 (2) “Affiliate” means any parent or subsidiary entity of the Company, or any other entity in whatever
form, of which the Company has any direct or indirect controlling ownership interest or management control, or vice-versa, as determined by the Company. For purposes of clarity and not limitation, (i) Riverstone Investment Group LLC, Bayou City

Agreement, and (ii) Silver Run is an Affiliate of the Company. 
 (3) “Anticipatory Termination” means

Section 409A), but only if (a) the Executive’s employment with the Company was (i) terminated by the Company without Cause or (ii) terminated by the Executive for Good Reason, and (b) it is reasonably demonstrated by

registration statement filed with the Securities and Exchange Commission or a transaction or series of transactions that meets the requirements of clauses (1) and (2) of subsection (C) below) whereby any “person” or related
“group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) (other than Silver Run, any of its subsidiaries, an employee benefit plan maintained by Silver Run or any of its
subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, Silver Run) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of securities of Silver Run possessing more than 50% of the total combined voting power of Silver Run’s securities outstanding immediately after such acquisition; or

by Silver Run’s stockholders was approved by a vote of at least two-thirds of the Directors then still in office who either were Directors at the beginning of such
two-year period or whose election or nomination for election was previously so approved, cease for any reason to constitute a majority thereof; or 

(C) The consummation by Silver Run (whether directly involving Silver Run or indirectly involving Silver Run through one or
more intermediaries) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of Silver Run’s assets in any single transaction or series of related
transactions, or (z) the acquisition of assets or stock of another entity, in each case other than a transaction: 

(1) which results in Silver Run’s voting securities outstanding immediately before the transaction continuing to

 (2) after which no person or group beneficially owns voting securities
representing 50% or more of the combined voting power of the Successor Entity; provided, however, that no person or group shall be treated for purposes of this clause (2) as beneficially owning 50% or more of the combined voting power of the
Successor Entity solely as a result of the voting power held in Silver Run prior to the consummation of the transaction. 

Notwithstanding the foregoing, in no event shall the following constitute a Change in Control: (i) the Transaction or any

other sale or disposition of such Midstream Assets directly or indirectly by Silver Run in connection with such initial public offering. 

If a Change in Control constitutes a payment event with respect to any amount, benefit or award (or portion of any amount,
benefit or award) that provides for the deferral of compensation that is subject to Section 409A, to the extent required to avoid the imposition of additional taxes under Section 409A, the transaction or event described in subsection (A),
(B) or (C) above with respect to such amount, benefit or award (or portion thereof) shall only constitute a Change in Control for purposes of the payment timing of such amount, benefit or award if such transaction also constitutes a
“change in control event,” as defined in Treasury Regulation Section 1.409A- 3(i)(5). 
 The Board as in
effect immediately prior to the occurrence of a Change in Control shall have full and final authority, which shall be exercised in its discretion, to determine conclusively whether a Change in Control has occurred pursuant to the above definition,
the date of the occurrence of such Change in Control and any incidental matters relating thereto; provided that any exercise of such authority in conjunction with a determination regarding whether a Change in Control is a “change in control
event” (as defined in Treasury Regulation Section 1.409A-3(i)(5)) shall be determined on a basis consistent with such regulation. 

(7) “Change in Control Date” means the effective date of the occurrence of a Change in Control.

 (11) “Director” means a Board member. 

(12) “Disability” shall mean that (a) Executive is unable to engage in any substantial gainful activity
by reason of any medically determinable physical or mental impairment which can be expected to result in death or last for a continuous period of not less than 12 months, or (b) by reason of any medically determinable physical or mental
impairment which can be expected to result in death or to last for a continuous period of not less than 12 months, Executive is receiving income replacement for a period of not less than three months under an accident and health plan covering
employees of the Company. Evidence of such Disability shall be certified by a physician acceptable to both the Company and Executive. In the event that the Parties are not able to agree on the choice of a physician, each shall select one physician
who, in turn, shall select a third physician to render such certification. All reasonable costs directly relating to the determination of whether Executive has incurred a Disability for purposes of this Agreement shall be paid by the Company.
Executive agrees to submit to any examinations that are reasonably required by the attending physician or other healthcare service providers to determine whether Executive has a Disability. 

(13) “Dispute” means any dispute, disagreement, claim, or controversy arising from, in connection with, or
relating to (a) the employment, or termination of employment, of Executive, or (b) the Agreement, or the validity, interpretation, performance, breach or termination of the Agreement. 

(14) “Exchange Act” means the Securities Exchange Act of 1934, as amended. 

(15) “Good Reason” means, other than during the fifteen (15)-month period following a Change in Control, the
occurrence of any of the following without the Executive’s prior written consent, if not cured and corrected by the Company or Silver Run, or either of their successor(s), within 60 days after written notice thereof is provided by Executive to
the Company or its successor, provided such notice is delivered within 90 days after the occurrence of the applicable condition or event and that Executive resigns from employment with the Company within 90 days following expiration of such 60-day cure period: 
 (A) the demotion or reduction in title or rank of Executive with the
Company or Silver Run, except for any such demotion or reduction that occurs in connection with Executive’s termination of employment for Cause, Disability or death; 

  

					
		  	12	  	R. Smith Agreement

 (B) the reduction of the Executive’s annual base salary and/or target bonus
opportunity, as compared to his aggregate base salary and target bonus opportunity as effective immediately prior to such reduction, if such reduction of base salary and/or target bonus opportunity, on an aggregated basis, is five percent (5%) or
greater of the aggregate base salary and target bonus opportunity as effective immediately prior to such reduction; or 
 (C)
a relocation of Executive’s principal work location to a location in excess of 50 miles from its then current location. 
 During the
fifteen (15)-month period following a Change in Control, the definition of “Good Reason” shall have the same meaning as set out above except that clause (A) is replaced in its entirety with “the demotion or reduction in title or
rank of Executive with the Company or Silver Run, or the assignment to Executive of duties that are materially inconsistent with Executive’s positions, duties and responsibilities with the Company or Silver Run, or any removal of the Executive
from, or any failure to nominate for re-election the Executive to, any of such positions (other than a change due to the Executive’s Disability or as an accommodation under the American with Disabilities
Act), except for any such demotion, reduction, assignment, removal or failure that occurs in connection with Executive’s termination of employment for Cause, Disability or death;”. In all other respects, the definition of Good Reason will
be the same before and after a Change in Control. 
 For the avoidance of doubt, the closing of the Transaction will not by itself be deemed
to provide a basis for the Executive to resign for Good Reason. 
 (16) “No Severance Benefits Event” means
termination of Executive’s employment by the Company for Cause. 
 (17) “Silver Run” means Silver Run
Acquisition Corporation II, a Delaware corporation (whose name will change to Alta Mesa Resources, Inc. at the closing of the Transaction), or its successor in interest. 

7. Notice of Termination. Any termination of Executive’s employment by the Company or the Executive other than for death shall be
communicated by Notice of Termination to the other Party hereto. For purposes of this Agreement, the term “Notice of Termination” means a written notice which indicates the specific termination provision of this Agreement relied
upon, sets forth in reasonable detail the facts and circumstances claimed to provide a basis for termination of the Executive’s employment under the provision so indicated and specifies a Termination Date which, if submitted by Executive, shall
be at least thirty (30) days following the date of such Notice of Termination unless such termination is for Good Reason (in which case the requirements for a termination due to Good Reason shall apply); provided, however, that in the event
that Executive delivers a Notice of Termination to the Company, the Company may, in its sole discretion, change the Date of Termination to any date that occurs following the date of receipt of such Notice of Termination and is prior to the date
specified in such Notice of Termination. A Notice of Termination submitted by the Company may provide for a Termination Date on the date Executive receives the Notice of Termination, or any date thereafter elected by the Company in its sole
discretion. The failure by the Company or Executive to set forth in the Notice of Termination any fact or circumstance which contributes to a showing of Cause or Good Reason shall not waive any right of such Party hereunder or preclude such
Party from asserting such fact or circumstance in enforcing such Party’s rights hereunder. 
 8. No Mitigation. Except as provided
in Section 6(b)(2) for continued Health Plan coverage or Section 6(b)(3) regarding excess parachute payments, Executive shall not be required to mitigate the amount of any payment or other benefits provided
under this Agreement by seeking other employment or in any other manner. 
 9. Restrictive Covenants. As an inducement to the Company to
enter into this Agreement, Executive represents to, and covenants with or in favor of, the Company that Executive will comply with all of the restrictive covenants in Sections 9 through 17, as a condition to the Company’s
obligation to provide any benefits to Executive under this Agreement. 
 10. Trade Secrets. 

(a) Access to Trade Secrets. As of the Effective Date and on an ongoing basis, the Company agrees to give Executive access
to Trade Secrets which the Executive did not have access to, or knowledge of, before Executive’s commencement of employment with the Company. 

  

					
		  	13	  	R. Smith Agreement

 (b) Agreement Not to Use or Disclose Trade Secrets. In exchange for the
Company’s promises to provide Executive with access to Trade Secrets, and the other consideration and benefits provided to Executive under this Agreement, Executive agrees, during the Employment Period, and any time thereafter, not to disclose
to anyone, including, without limitation, any person, firm, corporation or other entity, or publish or use for any purpose, any Trade Secrets, except (1) as required in the ordinary course of the business of the Company or an Affiliate or
(2) as authorized by the Company or Affiliate, as applicable. Executive acknowledges that Trade Secrets (A) have been and will be developed or acquired by the Company (or an Affiliate) through the expenditure of substantial time, effort
and money and (B) provide the Company (or an Affiliate) with an advantage over competitors who do not know or use Trade Secrets. 

Executive shall hold in a fiduciary capacity for the benefit of the Company (or its Affiliate, as applicable) any Trade Secret relating to the
Company or any of its Affiliates, and their respective businesses, which (a) has been obtained by Executive during his employment by the Company (or any Affiliate) and (b) is not public knowledge other than via an unauthorized disclosure
made by Executive in violation of this Agreement. Executive acknowledges and agrees that all Trade Secrets are, and will continue to be, the exclusive property of the Company or Affiliate, as applicable. 

Executive shall not at any time disclose to any person or entity, or publish, or use for any unauthorized purpose, any Trade Secret, except as
the Company directs or under compulsion of law. Executive agrees to give notice to the Company of any attempt to compel disclosure of any Trade Secret within five (5) business days after Executive is informed that such disclosure is being, or
will be, compelled. Any such notice shall contain a copy of the subpoena, order or other process used to compel disclosure. 
 The agreements
and covenants in this Section 10(b) apply to all Trade Secrets, whether now known or later to become known to Executive. In addition, these provisions shall be in addition to, and not limit or restrict in any way, any other
confidentiality agreement or covenant between the Executive and the Company or any of its Affiliates. 

  

					
		  	14	  	R. Smith Agreement

 (c) Agreement to Refrain from Defamatory Statements. Executive shall
refrain, both during the Employment Period and thereafter, from publishing any oral or written statements about any directors, partners, officers, employees, agents, investors or representatives of the Company or any Affiliate that are
(1) slanderous, libelous, or defamatory; (2) disclose private or confidential information about the business affairs, directors, partners, officers, employees, agents, investors or representatives of the Company or any Affiliate;
(3) constitute an intrusion into the seclusion or private lives of any such person; (4) give rise to unreasonable publicity about the private life of any such person; (5) place any such person in a false light before the public; or
(6) constitute a misappropriation of the name or likeness of any such person. A violation or threatened violation of these restrictive covenants may be enjoined by a court of law notwithstanding the arbitration provisions of
Section 31. 
 (d) Definitions. The following terms, when used in this Agreement, are defined
below: 
 (1) “Restricted Territory” means any county, or equivalent political or governmental subdivision,
of any state, district, or territory of North America in which the Company or any of its Affiliates conducts its business; and any area adjacent to such counties, or equivalent political or governmental subdivision, to the extent such adjacent areas
are within a 50-mile radius of any (x) producing property or leasehold of the Company or any of its Affiliates or (y) assets relating to the gathering, processing, storage, treating or transmission
of oil or natural gas or otherwise generally considered “midstream” in nature in accordance with generally accepted U.S. oil and gas industry practices and customs (“Midstream Assets”) of the Company or any of its
Affiliates. 
 (2) “Trade Secrets” means any and all information and materials (in any form or medium) that
are proprietary to the Company or an Affiliate, or are treated as confidential by the Company or an Affiliate as part of, or relating to, any portion of its or their businesses (whether or not owned or developed by the Company or an Affiliate) and
that are not generally known by other persons or entities in the same type of business. 
 For purposes of the Agreement,
Trade Secrets include, without limitation, the following: all of the Company’s or Affiliate’s research, technical and business information, whether patentable or not, which is of a confidential, trade secret or proprietary character, and
which is either developed by the Executive alone, or with others or by others; all non-public information that the Company or an Affiliate has marked as confidential or has otherwise described to Executive
(either in writing or orally) as confidential; all non-public information concerning the Company’s or Affiliate’s products, services, prospective products or services, research, prospects, leases,

specifications; any proprietary information belonging to the Company or an Affiliate; all computer hardware or software manuals of the Company or an Affiliate; all Company or Affiliate training or instruction manuals; all Company or Affiliate
electronic data; and all computer system passwords and user codes. 
 11. Duty to Return Company Documents and Property. Upon the Termination
Date, Executive shall immediately return and deliver to the Company any and all papers, books, records, documents, memoranda and manuals, e-mail, electronic or magnetic recordings or data, including all copies
thereof, belonging to the Company or relating to its business, in Executive’s possession, whether prepared by Executive or others. If at any time after the Termination Date, Executive determines that Executive has any Trade Secrets in
Executive’s possession or control, Executive shall immediately return them to the Company, including all copies thereof. 
 12. Best
Efforts and Disclosure. Executive agrees that, while employed with the Company under this Agreement, Executive’s services shall be devoted on a full time basis to the Company’s business, and Executive shall use best efforts to
promote its success. Further, Executive shall promptly disclose to the Company all ideas, inventions, computer programs, and discoveries, whether or not patentable or copyrightable, which Executive may conceive or make, alone or with others, during
Executive’s period of employment with the Company or its Affiliates, whether or not during working hours, and which directly or indirectly: 
  

	 	(a)	relate to a matter within the scope, field, duties or responsibility of Executive’s employment with the Company or within the scope or field of the Company’s or an Affiliate’s business; or

  

	 	(b)	are based on any knowledge of the actual or anticipated business or interests of the Company; or 

  

	 	(c)	are aided by the use of time, materials, facilities or information of the Company or an Affiliate. 

Executive assigns to the Company, without further compensation, any and all rights, titles and interest in all such ideas, inventions, computer
programs and discoveries in all countries of the world. Executive recognizes that all ideas inventions, computer programs and discoveries of the type described above, conceived or made by Executive alone or with others within 12 months after
the Termination Date (voluntary or otherwise), are likely to have been conceived in significant part either while employed by the Company or as a direct result of knowledge Executive had of proprietary information or Trade Secrets. Accordingly,
Executive agrees that such ideas, inventions or discoveries shall be presumed to have been conceived during Executive’s period of employment with the Company or its Affiliates, unless and until the contrary is clearly established by the
Executive. 

  

					
		  	16	  	R. Smith Agreement

 13. Inventions and Other Works. Any and all writings, computer software, inventions, improvements,
processes, procedures and/or techniques which Executive may make, conceive, discover, or develop, either solely or jointly with any other person or persons, at any time during Executive’s period of employment with the Company or its
Affiliates, whether at the request or upon the suggestion of the Company or otherwise, which relate to or are useful in connection with any business now or hereafter carried on or contemplated by the Company, including developments or expansions of
its present fields of operations, shall be the sole and exclusive property of the Company. Executive agrees to take any and all actions necessary or appropriate so that the Company can prepare and present applications for copyright or letters patent
therefor, and secure such copyright or letters patent wherever possible, as well as reissue renewals, and extensions thereof, and obtain the record title to such copyright or patents. Executive shall not be entitled to any additional or special
compensation or reimbursement regarding any such writings, computer software, inventions, improvements, processes, procedures and techniques. Executive acknowledges that the Company from time to time may have agreements with other persons or
entities which impose obligations or restrictions on the Company regarding inventions made during the course of work thereunder or regarding the confidential nature of such work. Executive agrees to be bound by all such obligations and restrictions,
and to take all action necessary to discharge the obligations of the Company. 
 14. Non-Solicitation
Restriction. Executive hereby agrees that in order to protect Trade Secrets, it is necessary to enter into the following restrictive covenant, which is ancillary to the enforceable promises between the Company and Executive in
Sections 9 through 13 and other provisions of this Agreement. During the Executive’s employment and for a period of one (1) year following the Termination Date (regardless of the reason for termination),
Executive hereby covenants and agrees that he will not, directly or indirectly, without obtaining the express written consent of the Board, either individually or as a principal, partner, agent, consultant, contractor, employee, or as a director or
officer of any entity, or in any other manner or capacity whatsoever, except on behalf of the Company, solicit business, attempt to solicit business, or conduct business, in products or services competitive with any products or services offered or
performed by the Company or its Affiliates in any business which the Company or any of its Affiliates does business, prepared to conduct business as of the Termination Date (or if the applicable activity occurs before the Termination, Date, then as
of the date on which such activity occurs), or has any business interest within the Restricted Territory as of the Termination Date (or if the applicable activity occurs before the Termination, Date, then as of the date on which such activity
occurs), (a) from those individuals or entities with whom the Company or Affiliate conducted or prepared to conduct business in the Restricted Territory during the Executive’s employment with the Company or (b) with respect to any
assets or holdings in which the Company or Affiliate had any interest in the Restricted Territory at any time during the two-year period ending on the earlier of the Termination Date or the date on which such
activity occurs. 
 15. Non-Competition Restriction. Executive hereby agrees that in order to
protect Trade Secrets, it is necessary to enter into the following restrictive covenant, which is ancillary to the enforceable promises between the Company and Executive in Sections 9 through 14 and other provisions of this
Agreement. Executive hereby covenants and agrees that during Executive’s period of employment with the Company or its Affiliates, and for a period of one (1) year following the Termination Date (regardless of the reason for termination),
Executive will not, without obtaining the express written consent of the Company, engage in any capacity, directly or indirectly (whether as proprietor, stockholder, director, partner, employee, agent, independent contractor, consultant, trustee, or
in any other capacity), with respect to any entity engaged or 

  

					
		  	17	  	R. Smith Agreement

 
preparing to engage in the business of oil and gas exploration and production, the acquisition, development or operation of Midstream Assets or any other aspect of the Company’s or an
Affiliate’s business, in each case, within the Restricted Territory (a “Competing Enterprise”); provided, however, Executive shall not be deemed to be participating or engaging in a Competing Enterprise solely by virtue of the
ownership of not more than one percent (1%) of any class of stock or other securities which are publicly traded on a national securities exchange or in a recognized
over-the-counter market. 
 16. No Recruitment Restriction.
Executive agrees that during Executive’s period of employment with the Company or its Affiliates, and for a period of one (1) year following the Termination Date (regardless of the reason for termination), without obtaining the express
written consent of the Company, Executive shall not, either directly or indirectly, or by acting in concert with another person or entity, (a) hire any employee or independent contractor performing services for the Company or any Affiliate, or
any such individual who performed services for the Company or any Affiliate at any time during the one-year period ending on the earlier of the Termination Date or the date on which such hiring occurs, or
(b) solicit or influence or seek to solicit or influence, any employee or independent contractor performing services for the Company or any Affiliate, or any such individual who performed services for the Company or any Affiliate at any time
during the one-year period ending on the earlier of the Termination Date or the date on which such activity occurs, to terminate, reduce or otherwise adversely affect such individual’s employment or other
relationship with the Company or any Affiliate. 
 17. Business Opportunities. During Executive’s period of employment with the
Company or its Affiliates and for a period of one (1) year following the Termination Date (regardless of the reason for termination), the Executive assigns and agrees to assign without further compensation to the Company, its Affiliates and its
successors, assigns or designees, all of the Executive’s right, title and interest in and to all Business Opportunities (defined below), and further acknowledges and agrees that all Business Opportunities constitute the exclusive property of
the Company. The Executive shall present all Business Opportunities to the Company, and shall not exploit a Business Opportunity. For purposes of this Agreement, “Business Opportunities” means all business ideas, prospects,
or proposals pertaining to oil and gas exploration and production, the acquisition, development or operation of Midstream Assets or any other aspect of the Company’s or an Affiliate’s business, and any business the Company or any Affiliate
prepared to conduct, or contemplated conducting during Executive’s employment with the Company, which are developed by the Executive or originated by any third party and brought to the attention of the Executive, together with information
relating thereto; provided however, that for the one (1) year period following the Termination Date, “Business Opportunities” shall be limited to those Business Opportunities in the Restricted Territory. For the avoidance of doubt,
this Section 17 is not intended to limit or narrow the Executive’s duties or obligations under federal or state law with respect to corporate opportunities. 

18. Tolling. If Executive violates any of the restrictions contained in Sections 9 through 17, then notwithstanding any
provision hereof to the contrary, the restrictive period will be suspended and will not run in favor of Executive from the time of the commencement of any such violation, unless and until such time when the Executive cures the violation to the
reasonable satisfaction of the Company. 

  

					
		  	18	  	R. Smith Agreement

 19. Reformation. If a court or arbitrator rules that any time period or the geographic area
specified in any restrictive covenant in Sections 9 through 17 is unenforceable, then the time period will be reduced by the number of months, or the geographic area will be reduced by the elimination of such unenforceable
portion, or both, so that the restrictions may be enforced in the geographic area and for the time to the full extent permitted by law. 
 20.
No Previous Restrictive Agreements. Executive represents that, except as disclosed in writing to the Company as of the Effective Date, Executive is not bound by the terms of any agreement with any previous employer or other third party to
(a) refrain from using or disclosing any confidential or proprietary information in the course of Executive’s employment by the Company or (b) refrain from competing, directly or indirectly, with the business of such previous
employer or any other person or entity. Executive further represents that Executive’s performance under this Agreement and work duties for the Company do not, and will not, breach any agreement to keep in confidence any proprietary
information, knowledge or data acquired by Executive in confidence or in trust prior to Executive’s employment with the Company, and Executive will not disclose to the Company or induce the Company to use any confidential or proprietary
information or material belonging to any previous employer or others. 
 21. Conflicts of Interest. In keeping with Executive’s
fiduciary duties to the Company, Executive hereby agrees that Executive shall not become involved in a conflict of interest, or upon discovery thereof, allow such a conflict to continue at any time during Executive’s period of employment with
the Company or its Affiliates. In this respect, Executive agrees to fully comply with the conflict of interest agreement entered into by Executive as an employee, officer or director of the Company or an Affiliate. In the instance of a violation of
the conflict of interest agreement to which Executive is a party, it may be necessary for the Company to terminate Executive’s employment for Cause. 

22. Remedies. Executive acknowledges that the restrictions contained in Sections 9 through 21 of this Agreement, in view of
the nature of the Company’s business, are reasonable and necessary to protect the Company’s legitimate business interests, and that any violation of this Agreement would result in irreparable injury to the Company. Notwithstanding the
arbitration provisions in Section 31, in the event of a breach or a threatened breach by Executive of any provision of Sections 9 through 21 of this Agreement, the Company shall be entitled to a
temporary restraining order and injunctive relief restraining Executive from the commission of any breach, and to recover the Company’s attorneys’ fees, costs and expenses related to the breach or threatened breach. Nothing contained in
this Agreement shall be construed as prohibiting the Company from pursuing any other remedies available to it for any such breach or threatened breach, including, without limitation, the recovery of money damages, attorneys’ fees, and costs.
These covenants and agreements shall each be construed as independent of any other provisions in this Agreement, and the existence of any claim or cause of action by Executive against the Company, whether predicated on this Agreement or otherwise,
shall not constitute a defense to the enforcement by the Company of such covenants and agreements. 
 23. No Interference.
Notwithstanding any other provision of this Agreement, (a) Executive may disclose confidential information when required to do so by a court of competent jurisdiction, by any governmental agency having authority over Executive or the
business of the Company or by any administrative body or legislative body (including a committee thereof) with 

  

					
		  	19	  	R. Smith Agreement

 
jurisdiction to order Executive to divulge, disclose or make accessible such information, in each case, subject to Executive’s obligations to notify the Company under
Section 10(b); and (b) nothing in this Agreement is intended to interfere with Executive’s right to (1) report possible violations of state or federal law or regulation to any governmental or law enforcement
agency or entity; (2) make other disclosures that are protected under the whistleblower provisions of state or federal law or regulation (including the right to receive an award for information provided to any such government agencies); (3)
file a claim or charge any governmental agency or entity; or (4) testify, assist, or participate in an investigation, hearing, or proceeding conducted by any governmental or law enforcement agency or entity, or any court. For purposes of
clarity, in making or initiating any such reports or disclosures or engaging in any of the conduct outlined in subsection (b) above, Executive may disclose confidential information to the extent necessary to such governmental or law enforcement
agency or entity or such court, need not seek prior authorization from the Company, and is not required to notify the Company of any such reports, disclosures or conduct. 

24. Defend Trade Secrets Act. Executive is hereby notified in accordance with the Defend Trade Secrets Act of 2016 that Executive will not be
held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (a) is made (1) in confidence to a federal, state, or local government official, either directly or indirectly, or to
an attorney; and (2) solely for the purpose of reporting or investigating a suspected violation of law; or (b) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Executive files a lawsuit
for retaliation against the Company for reporting a suspected violation of law, Executive may disclose the Company’s trade secrets to Executive’s attorney and use the trade secret information in the court proceeding if Executive files any
document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. 
 25. Withholdings;
Right of Offset . The Company may withhold and deduct from any benefits and payments made or to be made pursuant to this Agreement (a) all federal, state, local and other taxes as may be required pursuant to any law or governmental
regulation or ruling, (b) all other normal employee deductions made with respect to Company’s employees generally, and (c) any advances made to Executive and owed to Company. 

26. Nonalienation. The right to receive payments under this Agreement shall not be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge or encumbrance by Executive, dependents or beneficiaries of Executive, or to any other person who is or may become entitled to receive such payments hereunder. The right to receive payments hereunder shall not be subject
to or liable for the debts, contracts, liabilities, engagements or torts of any person who is or may become entitled to receive such payments, nor may the same be subject to attachment or seizure by any creditor of such person under any
circumstances, and any such attempted attachment or seizure shall be void and of no force and effect. 
 27. Incompetent or Minor Payees.
Should the Company determine, in its discretion, that any person to whom any payment is payable under this Agreement has been determined to be legally incompetent or is a minor, any payment due hereunder, notwithstanding any other provision of
this Agreement to the contrary, may be made in any one or more of the following ways: (a) directly to such minor or person; (b) to the legal guardian or other duly appointed 

  

					
		  	20	  	R. Smith Agreement

 
personal representative of the person or estate of such minor or person; or (c) to such adult or adults as have, in the good faith knowledge of the Company, assumed custody and support of
such minor or person; and any payment so made shall constitute full and complete discharge of any liability under this Agreement in respect to the amount paid. 

28. Severability. It is the desire of the Parties hereto that this Agreement be enforced to the maximum extent permitted by law, and should any
provision contained herein be held unenforceable by a court of competent jurisdiction or arbitrator (pursuant to Section 31), the Parties hereby agree and consent that such provision shall be reformed to create a valid and
enforceable provision to the maximum extent permitted by law; provided, however, if such provision cannot be reformed, it shall be deemed ineffective and deleted herefrom without affecting any other provision of this Agreement. This Agreement should
be construed by limiting and reducing it only to the minimum extent necessary to be enforceable under then applicable law. 
 29. Title and
Headings; Construction. In the interpretation of the Agreement, except where the context clearly otherwise requires: 

(a) “including” or “include” does not denote or imply any limitation; 

(b) “or” has the inclusive meaning “and/or”; 

(c) the singular includes the plural, and vice versa, and each gender includes each of the others; 

(d) captions or headings are only for reference and are not to be considered in interpreting the Agreement; 

(e) “Section” refers to a Section of the Agreement, unless otherwise stated in the Agreement; 

(f) the words “herein”, “hereof”, “hereunder” and other compounds of the word “here” shall refer
to the entire Agreement and not to any particular provision; and 
 (g) a reference to any statute, rule, or regulation includes any
amendment thereto or any statute, rule, or regulation enacted or promulgated in replacement thereof or as the successor thereto. 
 30. Governing Law;
Jurisdiction. All matters or issues relating to the interpretation, construction, validity, and enforcement of this Agreement shall be governed by the laws of the State of Texas, without giving effect to any choice-of-law principle that would cause the application of the laws of any jurisdiction other than Texas. Jurisdiction and venue of any action or proceeding relating to this Agreement or any Dispute (to the
extent arbitration is not required under Section 31) shall be exclusively in Harris County, Texas. 

  

					
		  	21	  	R. Smith Agreement

 31. Mandatory Arbitration. Except as provided in subsection (h) of this
Section 31, any Dispute must be resolved by binding arbitration in accordance with the following: 

(a) Either Party may begin arbitration by filing a demand for arbitration in accordance with the Commercial Arbitration Rules of the AAA
(the “Arbitration Rules”) and concurrently notifying the other Party of that demand. If the Parties are unable to agree upon a panel of three neutral arbitrators within twenty days after the demand for arbitration was filed (the
Parties agree to a reasonable, one-time extension of that twenty-day period), either Party may request the Houston, Texas office of the American Arbitration Association
(“AAA”) to appoint the arbitrator or arbitrators necessary to complete the panel in accordance with the Arbitration Rules. Each arbitrator so appointed shall be deemed accepted by the Parties as part of the panel. Notwithstanding
the foregoing, the Parties, by mutual consent, may agree to a single arbitrator instead of a panel of three arbitrators and, in such event, references herein to “panel” shall refer to the single appointed arbitrator. 

(b) The arbitration shall be conducted in the Houston, Texas metropolitan area at a place and time agreed upon by the Parties with the
panel, or if the Parties cannot agree, as designated by the panel. The panel may, however, call and conduct hearings and meetings at such other places as the Parties may agree or as the panel may, on the motion of one Party, determine to be
necessary to obtain significant testimony or evidence. 
 (c) The panel may authorize any and all forms of discovery upon a
Party’s showing of need that the requested discovery is likely to lead to material evidence needed to resolve the Dispute and is not excessive in scope, timing, or cost. 

(d) The arbitration shall be subject to the Federal Arbitration Act and conducted in accordance with the Arbitration Rules to the extent
that they do not conflict with this Section 31. The Parties and the panel may, however, agree to vary to provisions of this Section 31 or the matters otherwise governed by the Arbitration Rules as
permitted by law. 
 (e) The arbitration hearing shall be held within 60 days after the appointment of the panel. The panel’s
final decision or award shall be made within 30 days after the hearing. That final decision or award shall be made by unanimous or majority vote or consent of the arbitrators constituting the panel, and shall be deemed issued at the place of
arbitration. The panel’s final decision or award shall be based on the terms and conditions of this Agreement and applicable law. 

(f) The panel’s final decision or award may include injunctive relief in response to any actual or impending breach of this
Agreement or any other actual or impending action or omission of a Party under or in connection with this Agreement. 
 (g) The
panel’s final decision or award shall be final and binding upon the Parties, and judgment upon that decision or award may be entered in any court having jurisdiction. The Parties waive any right to apply or appeal to any court for relief from
the preceding sentence or from any decision of the panel that is made before the final decision or award. 
 (h) Nothing in this
Section 31 limits the right of either Party to apply to a court having jurisdiction to (i) enforce the agreement to arbitrate in accordance with this Section 31, (ii) seek provisional or
temporary injunctive relief, in response to an actual or impending breach of the Agreement or otherwise so as to avoid an irreparable damage or maintain the status quo, 

  

					
		  	22	  	R. Smith Agreement

 
until a final arbitration decision or award is rendered or the Dispute is otherwise resolved, or challenge or vacate any final arbitration decision or award that does not comply with this
Section 31. In addition, nothing in this Section 31 prohibits the Parties from resolving any Dispute (in whole or in part) at any time by mutual agreement or compromise. This
Section 31 shall also not preclude the Parties at any time from mutually agreeing to pursue non-binding mediation of the Dispute. 

(i) The panel may proceed to an award notwithstanding the failure of any Party to participate in such proceedings. The prevailing Party
in the arbitration proceeding may be entitled to an award of reasonable attorneys’ fees incurred in connection with the arbitration in such amount, if any, as determined by the panel in its discretion. The costs of the arbitration shall be
borne equally by the Parties unless otherwise determined by the panel in its award. 
 (j) The panel shall be empowered to impose
sanctions and to take such other actions as it deems necessary to the same extent a judge could impose sanctions or take such other actions pursuant to the Federal Rules of Civil Procedure and applicable law. Each Party agrees to keep all Disputes
and arbitration proceedings strictly confidential except for disclosure of information required by applicable law which cannot be waived. 
 32.
Binding Effect; Third Party Beneficiaries. Subject to Section 37, this Agreement shall be binding upon and inure to the benefit of the Parties hereto, and to their respective heirs, executors, beneficiaries,
personal representatives, successors and permitted assigns hereunder; otherwise this Agreement shall not be for the benefit of any third parties. 

33. Entire Agreement; Amendment and Termination. This Agreement contains the entire agreement of the Parties hereto with respect to the matters
covered herein; moreover, this Agreement supersedes all prior and contemporaneous agreements and understandings, oral or written, between the Parties concerning the subject matter hereof, including any employment agreement between the Company and
Executive as in effect immediately before the Effective Date. This Agreement may be amended, waived or terminated only by a written instrument that is identified as an amendment, waiver or termination hereto, and is executed on behalf of both
Parties. Executive hereby acknowledges and represents that in executing this Agreement, he did not rely on, has not relied on, and specifically disavows any reliance on any communications, promises, statements, inducements, or representation(s),
oral or written, by the Company, except as expressly contained in this Agreement. The Parties represent that they relied on their own judgment in entering into this Agreement. 

34. Section 409A. 
 (a)
General. Any provisions of the Agreement that are subject to Section 409A of the Code and the regulations and other authoritative guidance issued thereunder (“Section 409A”), are intended to
comply with all applicable requirements of Section 409A, or an exemption from the application of Section 409A, and shall be interpreted and administered accordingly. Notwithstanding any provision of this Agreement to the contrary, a
termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amount or benefit that constitutes “non-qualified deferred
compensation” (within the meaning of Section 409A) upon or following a termination of the Executive’s 

  

					
		  	23	  	R. Smith Agreement

 
employment unless such termination is also a “separation from service” (as defined under Section 409A) (a “Separation from Service”) and, for purposes of any such
provision, references herein to a “termination,” “termination of employment” or like terms shall mean a Separation from Service, if applicable. Each payment under this Agreement shall be treated as a separate payment for purposes
of Section 409A. In no event may the Executive, directly or indirectly, designate the calendar year of any payment to be made under this Agreement. 

(b) Specified Employee. Notwithstanding any provision of this Agreement to the contrary, if any payment or other benefit
provided hereunder would be subject to additional taxes and interest under Section 409A because the timing of such payment is not delayed as required by Section 409A for a “specified employee” (as defined under
Section 409A), then if the Executive is on the date of Executive’s Separation from Service a specified employee, any such payment or benefit that Executive would otherwise be entitled to receive during the first six months
following the Separation from Service shall be accumulated and paid in a lump sum within ten (10) days after the date that is six months following the date of the Separation from Service, or such earlier date upon which such amount can be paid
under Section 409A without being subject to such additional taxes and interest such as, for example, upon the Executive’s death. Any remaining payments due to Executive under this Agreement shall be paid as otherwise provided in this
Agreement. 
 (c) Reimbursements and In-Kind Benefits. Notwithstanding any
provision of this Agreement to the contrary, any reimbursements or in-kind benefits provided under this Agreement that constitute “nonqualified deferred compensation” within the meaning of
Section 409A shall be paid to Executive no later than December 31 of the year following the year in which the expense was incurred, the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any
subsequent year, other than medical expenses referred to in Section 105(b) of the Code, and Executive’s right to reimbursement under this Agreement will not be subject to liquidation or exchange for other benefits. 

(d) No Section 409A Representations. Notwithstanding the foregoing, the Company makes no
representations, warranties, or guarantees regarding the tax consequences of this Agreement, or any payments made hereunder, under Section 409A or otherwise, and has advised the Executive to consult with Executive’s own tax
advisor. 
 35. Survival of Certain Provisions. Provisions of this Agreement which by their terms must survive the termination of this
Agreement shall survive any such termination or expiration of this Agreement or termination of Executive’s employment, as applicable, including, without limitation, Executive’s obligations under Sections 9 through 18 and the
Company’s obligations under Section 6. 
 36. Waiver of Breach. No waiver by any party hereto of a breach
of any provision of this Agreement by any other party, or of compliance with any condition or provision of this Agreement to be performed by such other party, will operate or be construed as a waiver of any subsequent breach by such other party or
any similar or dissimilar provision or condition at the same or any subsequent time. The failure of any party hereto to take any action by reason of any breach will not deprive such party of the right to take action at any time while such breach
continues. 

  

					
		  	24	  	R. Smith Agreement

 37. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of the
Company and its Affiliates (and its and their successors), as well as upon any person or entity acquiring, whether by merger, consolidation, purchase of assets, dissolution or otherwise, all or substantially all of the capital stock, business and/or
assets of the Company (or its successor) regardless of whether the Company is the surviving or resulting entity. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, dissolution or otherwise) to
all or substantially all of the capital stock, business or assets of the Company to expressly assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform it if no such succession
had occurred; provided, however, no such assumption shall relieve the Company or any of its Affiliates (or any successor thereof) of any of its duties or obligations hereunder unless otherwise agreed, in writing, by Executive. 

This Agreement shall inure to the benefit of and be enforceable by Executive’s personal or legal representative, executors,
administrators, successors, and heirs. In the event of the death of Executive while any amount is payable hereunder, all such amounts shall be paid to the Designated Beneficiary. 

38. Notice. Each notice or other communication required or permitted under this Agreement shall be in writing and transmitted, delivered, or sent
by personal delivery, prepaid courier or messenger service (whether overnight or same-day), or prepaid certified United States mail (with return receipt requested), addressed (in any case) to the other party
at the address for that party set forth below that party’s signature on this Agreement, or at such other address as the recipient has designated by Notice to the other party, by electronic mail, delivery and read receipt required, or by
facsimile, confirmation of delivery required. 
 Each notice or communication so transmitted, delivered, or sent (a) in person,
by courier or messenger service, or by certified United States mail shall be deemed given, received, and effective on the date delivered to or refused by the intended recipient (with the return receipt, or the equivalent record of the courier or
messenger, being deemed conclusive evidence of delivery or refusal), or (b) by telecopy or facsimile shall be deemed given received) and effective on the date of actual receipt (with the confirmation of transmission being deemed conclusive
evidence of receipt, except where the intended recipient has promptly notified the other party that the transmission is illegible). Nevertheless, if the date of delivery or transmission is not a business day, or if the delivery or transmission is
after 5:00 p.m. (local time) on a business day, the notice or other communication shall be deemed given, received, and effective on the next business day. 

39. Executive Acknowledgment. Executive acknowledges (a) being knowledgeable and sophisticated as to business matters, including the subject
matter of this Agreement, (b) having read this Agreement and understanding its terms and conditions, (c) having been given an ample opportunity to discuss this Agreement with his personal legal counsel prior to execution, and (d) that
no strict rules of construction shall apply for or against the drafter or any other party. Executive hereby represents that he is free to enter into this Agreement including, without limitation, that he is not subject to any covenant not to compete
or confidentiality agreement that conflicts with this Agreement. 

  

					
		  	25	  	R. Smith Agreement

 40. Counterparts. This Agreement may be executed in any number of counterparts, each of which when
so executed and delivered shall be an original, but all such counterparts shall together constitute one and the same instrument. Each counterpart may consist of a copy hereof containing multiple signature pages, each signed by one party hereto, but
together signed by both Parties. 
 41. Parent Acknowledgment and Guarantee. Alta Mesa is the direct or indirect parent of the Company.
Alta Mesa hereby unconditionally guarantees full and timely performance of the obligations of the Company and its Affiliates under this Agreement. The foregoing guarantee shall include the guarantee of the payment of all benefits and payments due
Executive hereunder as a result of the nonperformance of any of such obligations or agreements so guaranteed or as a result of the nonperformance of this guarantee. Executive may, at his option, proceed against Alta Mesa for damages for default in
the performance thereof, without first proceeding against the Company or against any of its properties or Affiliates. Alta Mesa further agrees that its guarantee shall be an irrevocable guarantee and shall continue in effect notwithstanding any
extension or modification of any guaranteed obligation, any assumption of any such guaranteed obligation by any other party, or any other act or thing which might otherwise operate as a legal or equitable discharge of a guarantor, and Alta Mesa
hereby waives all special suretyship defenses and notice requirements. This guarantee shall also be binding upon all successors and assigns of all of substantially all of the business or assets of Alta Mesa. Section 31
shall apply to Disputes between Alta Mesa and Executive mutatis mutandis.

Agreement to be executed in its name and on its behalf by its duly authorized officer, and Alta Mesa has caused this Agreement to be executed in its name and on its behalf by its duly authorized officer solely for purposes of Section 41 of the

 Exhibit 10.19 

 

ALTA MESA RESOURCES, INC. 

2018 LONG TERM INCENTIVE PLAN 

ARTICLE I. 
 PURPOSE

 The Plan’s purpose is to enhance the Company’s ability to attract, retain and motivate persons who make (or are expected to
make) important contributions to the Company by providing these individuals with equity ownership opportunities. Capitalized terms used in the Plan are defined in Article XI. 

ARTICLE II. 
 ELIGIBILITY

 Service Providers are eligible to be granted Awards under the Plan, subject to the limitations described herein. 

ARTICLE III. 

ADMINISTRATION AND DELEGATION 

3.1 Administration. The Plan is administered by the Administrator. The Administrator has authority to determine which Service Providers
receive Awards, grant Awards and set Award terms and conditions, subject to the conditions and limitations in the Plan. The Administrator also has the authority to take all actions and make all determinations under the Plan, to interpret the Plan
and Award Agreements and to adopt, amend and repeal Plan administrative rules, guidelines and practices as it deems advisable. The Administrator may correct defects and ambiguities, supply omissions and reconcile inconsistencies in the Plan or any
Award as it deems necessary or appropriate to administer the Plan and any Awards. The Administrator’s determinations under the Plan are in its sole discretion and will be final and binding on all persons having or claiming any interest in the
Plan or any Award. 
 3.2 Appointment of Committees. To the extent Applicable Laws permit, the Board may delegate any or all of its
powers under the Plan to one or more Committees or officers of the Company or any of its Subsidiaries. The Board may abolish any Committee or re-vest in itself any previously delegated authority at any time.

 ARTICLE IV. 
 STOCK
AVAILABLE FOR AWARDS 
 4.1 Number of Shares. Subject to adjustment under Article VIII and the terms of this
Article IV, Awards may be made under the Plan covering up to the Overall Share Limit. 
 4.2 Share Recycling. If all or any part
of an Award expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, canceled without having been fully exercised or forfeited, in any case, in a manner that results in the Company acquiring Shares covered by the Award at a
price not greater than the price (as adjusted to reflect any Equity Restructuring) paid by the Participant for such Shares or not issuing any Shares covered by the Award, the unused Shares covered by the Award will again be available for Award
grants under the Plan. The payment of Dividend Equivalents in cash in conjunction with any outstanding Awards shall not count against the Overall Share Limit. Notwithstanding anything to the contrary contained herein, the following Shares shall not
be added to the Shares authorized for grant under Section 4.1 and shall not be available for future grants of 

 
Awards: (i) Shares tendered by the Participant or withheld by the Company in payment of the exercise price of an Option; (ii) Shares tendered by the Participant or withheld by the
Company to satisfy any tax withholding obligation with respect to an Award; (iii) Shares subject to a Stock Appreciation Right that are not issued in connection with the stock settlement of the Stock Appreciation Right on exercise thereof; and
(iv) Shares purchased on the open market with the cash proceeds from the exercise of Options. 
 4.3 Incentive Stock Option
Limitations. Notwithstanding anything to the contrary herein, no more than 50,000,000 Shares may be issued pursuant to the exercise of Incentive Stock Options. 

4.4 Substitute Awards. In connection with an entity’s merger or consolidation with the Company or any Subsidiary or the
Company’s or any Subsidiary’s acquisition of an entity’s property or stock, the Administrator may grant Awards in substitution for any options or other stock or stock-based awards granted before such merger or consolidation by such
entity or its affiliate. Substitute Awards may be granted on such terms as the Administrator deems appropriate, notwithstanding limitations on Awards in the Plan. Substitute Awards will not count against the Overall Share Limit (nor shall Shares
subject to a Substitute Award be added to the Shares available for Awards under the Plan as provided above), except that Shares acquired by exercise of substitute Incentive Stock Options will count against the maximum number of Shares that may be
issued pursuant to the exercise of Incentive Stock Options under the Plan. Additionally, in the event that a company acquired by the Company or any Subsidiary or with which the Company or any Subsidiary combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such
pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration
payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan (and Shares subject to such Awards shall not
be added to the Shares available for Awards under the Plan as provided above); provided that Awards using such available shares shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not Employees or Directors prior to such acquisition or combination. 

4.5 Non-Employee Director Compensation. Notwithstanding any provision to the contrary in the
Plan, the Administrator may establish compensation for non-employee Directors from time to time, subject to the limitations in the Plan. The Administrator will from time to time determine the terms, conditions
and amounts of all such non-employee Director compensation in its discretion and pursuant to the exercise of its business judgment, taking into account such factors, circumstances and considerations as it
shall deem relevant from time to time, provided that the sum of any cash compensation, or other compensation, and the value (determined as of the grant date in accordance with Financial Accounting Standards Board Accounting Standards Codification
Topic 718, or any successor thereto) of Awards granted to a non-employee Director as compensation for services as a non-employee Director during any fiscal year of the
Company may not exceed $500,000. The Administrator may make exceptions to this limit for individual non-employee Directors in extraordinary circumstances, as the Administrator may determine in its discretion,
provided that the non-employee Director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee Directors. 

  
 2 

 ARTICLE V. 

STOCK OPTIONS AND STOCK APPRECIATION RIGHTS 

5.1 General. The Administrator may grant Options or Stock Appreciation Rights to Service Providers subject to the limitations in the
Plan, including any limitations in the Plan that apply to Incentive Stock Options. The Administrator will determine the number of Shares covered by each Option and Stock Appreciation Right, the exercise price of each Option and Stock Appreciation
Right and the conditions and limitations applicable to the exercise of each Option and Stock Appreciation Right, and such terms and conditions shall be included in the Participant’s Award Agreement. A Stock Appreciation Right will entitle the
Participant (or other person entitled to exercise the Stock Appreciation Right) to receive from the Company upon exercise of the exercisable portion of the Stock Appreciation Right an amount determined by multiplying the excess, if any, of the Fair
Market Value of one Share on the date of exercise over the exercise price per Share of the Stock Appreciation Right by the number of Shares with respect to which the Stock Appreciation Right is exercised, subject to any limitations of the Plan or
that the Administrator may impose and payable in cash, Shares valued at Fair Market Value or a combination of the two as the Administrator may determine or provide in the Award Agreement. 

5.2 Exercise Price. The Administrator will establish each Option’s and Stock Appreciation Right’s exercise price and specify
the exercise price in the Award Agreement. The exercise price will not be less than 100% of the Fair Market Value on the grant date of the Option or Stock Appreciation Right. Notwithstanding the foregoing, if on the last day of the term of an Option
or Stock Appreciation Right the Fair Market Value of one Share exceeds the applicable exercise or base price per Share, the Participant has not exercised the Option or Stock Appreciation Right and remains employed by the Company or one of its
Subsidiaries and the Option or Stock Appreciation Right has not expired, the Option or Stock Appreciation Right shall be deemed to have been exercised by the Participant on such day with payment made by withholding Shares otherwise issuable in
connection with its exercise. In such event, the Company shall deliver to the Participant the number of Shares for which the Option or Stock Appreciation Right was deemed exercised, less the number of Shares required to be withheld for the payment
of the total purchase price and required withholding taxes; provided, however, any fractional Share shall be settled in cash. 
 5.3
Duration. Each Option or Stock Appreciation Right will be exercisable at such times and as specified in the Award Agreement, provided that the term of an Option or Stock Appreciation Right will not exceed ten years. Notwithstanding the
foregoing and unless determined otherwise by the Company, in the event that on the last business day of the term of an Option or Stock Appreciation Right (other than an Incentive Stock Option) (i) the exercise of the Option or Stock
Appreciation Right is prohibited by Applicable Law, as determined by the Company, or (ii) Shares may not be purchased or sold by the applicable Participant due to any Company insider trading policy (including blackout periods) or a “lock-up” agreement undertaken in connection with an issuance of securities by the Company, the term of the Option or Stock Appreciation Right shall be extended until the date that is thirty (30) days
after the end of the legal prohibition, black-out period or lock-up agreement, as determined by the Company; provided, however, in no event shall the extension last
beyond the ten year term of the applicable Option or Stock Appreciation Right. Notwithstanding the foregoing, if the Participant, prior to the end of the term of an Option or Stock Appreciation Right, violates the non-competition, non-solicitation, confidentiality or other similar restrictive covenant provisions of any employment contract, confidentiality and nondisclosure agreement or
other agreement between the Participant and the Company or any of its Subsidiaries, and such violation results in a material injury to the Company or any of its Subsidiaries (as determined by the Administrator), the right of the Participant and the
Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall terminate immediately upon such violation, unless the Company otherwise determines. In addition, if, prior to the end of the term of an
Option or Stock Appreciation Right, the Participant is given notice by the Company or any of its Subsidiaries of the Participant’s Termination of Service by the Company or any of its Subsidiaries for Cause, and the effective date of such
Termination of Service is subsequent to the date of the delivery of such notice, the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant shall be suspended from
the time of the delivery of such notice until the earlier of (i) such time as it is determined or otherwise agreed that the 

  
 3 

 
Participant’s service as a Service Provider will not be terminated for Cause as provided in such notice or (ii) the effective date of the Participant’s Termination of Service by
the Company or any of its Subsidiaries for Cause (in which case the right of the Participant and the Participant’s transferees to exercise any Option or Stock Appreciation Right issued to the Participant will terminate immediately upon the
effective date of such Termination of Service). 
 5.4 Exercise. Options and Stock Appreciation Rights may be exercised by delivering
to the Company a written notice of exercise, in a form the Administrator approves (which may be electronic), signed by the person authorized to exercise the Option or Stock Appreciation Right, together with, as applicable, payment in full
(i) as specified in Section 5.5 for the number of Shares for which the Award is exercised and (ii) as specified in Section 9.5 for any applicable taxes. Unless the Administrator otherwise determines, an Option or Stock
Appreciation Right may not be exercised for a fraction of a Share. 
 5.5 Payment Upon Exercise. Subject to
Section 10.8, any Company insider trading policy (including blackout periods) and Applicable Laws, the exercise price of an Option must be paid by: 

(a) cash, wire transfer of immediately available funds or by check payable to the order of the Company, provided that the Company may limit the
use of one of the foregoing payment forms if one or more of the payment forms below is permitted; 
 (b) if there is a public market for
Shares at the time of exercise, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to
deliver promptly to the Company sufficient funds to pay the exercise price, or (B) the Participant’s delivery to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly
to the Company cash or a check sufficient to pay the exercise price; provided that such amount is paid to the Company at such time as may be required by the Administrator; 

(c) to the extent permitted by the Administrator, delivery (either by actual delivery or attestation) of Shares owned by the Participant valued
at their Fair Market Value; 
 (d) to the extent permitted by the Administrator, surrendering Shares then issuable upon the Option’s
exercise valued at their Fair Market Value on the exercise date; 
 (e) to the extent permitted by the Administrator, delivery of a
promissory note or any other property that the Administrator determines is good and valuable consideration; or 
 (f) to the extent permitted
by the Company, any combination of the above payment forms approved by the Administrator. 
 ARTICLE VI. 

RESTRICTED STOCK; RESTRICTED STOCK UNITS 

6.1 General. The Administrator may grant Restricted Stock, or the right to purchase Restricted Stock, to any Service Provider, subject
to the Company’s right to repurchase all or part of such shares at their issue price or other stated or formula price from the Participant (or to require forfeiture of such shares) if conditions the Administrator specifies in the Award
Agreement are not satisfied before the end of the applicable restriction period or periods that the Administrator establishes for such Award. In addition, the Administrator may grant to Service Providers Restricted Stock Units, which may be subject
to vesting and forfeiture conditions during the applicable restriction period or periods, as set forth in an Award Agreement. The Administrator will determine and set forth in the Award Agreement the terms and conditions for each Restricted Stock
and Restricted Stock Unit Award, subject to the conditions and limitations contained in the Plan. 

  
 4 

 6.2 Restricted Stock. 

(a) Dividends. Participants holding shares of Restricted Stock will be entitled to all ordinary cash dividends paid with respect to such
Shares, unless the Administrator provides otherwise in the Award Agreement. In addition, unless the Administrator provides otherwise, if any dividends or distributions are paid in Shares, or consist of a dividend or distribution to holders of Common
Stock of property other than an ordinary cash dividend, the Shares or other property will be subject to the same restrictions on transferability and forfeitability as the shares of Restricted Stock with respect to which they were paid. In addition,
with respect to a share of Restricted Stock, dividends which are paid prior to vesting shall only be paid out to the Participant to the extent that the vesting conditions are subsequently satisfied and the share of Restricted Stock vests. 

(b) Stock Certificates. The Company may require that the Participant deposit in escrow with the Company (or its designee) any stock
certificates issued in respect of shares of Restricted Stock, together with a stock power endorsed in blank. 
 (c) Voting Rights.
Participants holding Shares of Restricted Stock will be entitled to all voting rights in such Shares, unless the Administrator provides otherwise in the Award Agreement. 

6.3 Restricted Stock Units. 

(a) Settlement. The Administrator may provide that settlement of Restricted Stock Units will occur upon or as soon as reasonably
practicable after the Restricted Stock Units vest or will instead be deferred, on a mandatory basis or at the Participant’s election, in a manner intended to comply with Section 409A. 

(b) Stockholder Rights. A Participant will have no rights of a stockholder with respect to Shares subject to any Restricted Stock Unit
unless and until the Shares are delivered in settlement of the Restricted Stock Unit. 
 (c) Dividend Equivalents. If the
Administrator provides, a grant of Restricted Stock Units may provide a Participant with the right to receive Dividend Equivalents. Dividend Equivalents may be paid currently or credited to an account for the Participant, settled in cash or Shares
and subject to the same restrictions on transferability and forfeitability as the Restricted Stock Units with respect to which the Dividend Equivalents are granted and subject to other terms and conditions as set forth in the Award Agreement. In
addition, Dividend Equivalents with respect to an Award that are based on dividends paid prior to the vesting of such Award shall only be paid out to the Participant to the extent that the vesting conditions are subsequently satisfied and the Award
vests. 
 ARTICLE VII. 

OTHER STOCK OR CASH BASED AWARDS 

Other Stock or Cash Based Awards may be granted to Participants, including Awards entitling Participants to receive Shares to be delivered in
the future and including annual or other periodic or long-term cash bonus awards (whether based on specified Performance Criteria or otherwise), in each case subject to any conditions and limitations in the Plan and the applicable Award Agreement.
Such Other 

  
 5 

 
Stock or Cash Based Awards will also be available as a payment form in the settlement of other Awards, as standalone payments and as payment in lieu of compensation to which a Participant is
otherwise entitled. Other Stock or Cash Based Awards may be paid in Shares, cash or other property, as the Administrator determines. Subject to the provisions of the Plan, the Administrator will determine the terms and conditions of each Other Stock
or Cash Based Award, including any purchase price, performance goal (which may be based on the Performance Criteria), transfer restrictions, vesting conditions, and payment terms, which will be set forth in the applicable Award Agreement. 

ARTICLE VIII. 

ADJUSTMENTS FOR CHANGES IN COMMON STOCK 

AND CERTAIN OTHER EVENTS 

8.1 Equity Restructuring. In connection with any Equity Restructuring, notwithstanding anything to the contrary in this
Article VIII, the Administrator will equitably adjust each outstanding Award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding Award and/or the
Award’s exercise price or grant price (if applicable), granting new Awards to Participants, and making a cash payment to Participants. The adjustments provided under this Section 8.1 will be final and binding on the affected Participant
and the Company; provided that the Administrator will determine whether an adjustment is equitable. 
 8.2 Corporate Transactions. In
the event of any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation,
dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or other rights
to purchase Common Stock or other securities of the Company, other similar corporate transaction or event, other unusual or nonrecurring transaction or event affecting the Company or its financial statements or any change in any Applicable Laws or
accounting principles, the Administrator, on such terms and conditions as it deems appropriate, either by the terms of the Award or by action taken prior to the occurrence of such transaction or event (except that action to give effect to a change
in Applicable Law or accounting principles may be made within a reasonable period of time after such change) and either automatically, or upon the Participant’s request, is hereby authorized to take any one or more of the following actions
whenever the Administrator determines that such action is appropriate in order to (x) prevent dilution or enlargement of the benefits or potential benefits intended by the Company to be made available under the Plan or with respect to any Award
granted or issued under the Plan, (y) to facilitate such transaction or event, or (z) give effect to such changes in Applicable Laws or accounting principles: 

(a) To provide for the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the
amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such Award, as applicable; provided that, if the amount that could
have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights, in any case, is equal to or less than zero, then the Award may be terminated without payment; 

(b) To provide that such Award shall vest and, to the extent applicable, be exercisable as to all Shares covered thereby, notwithstanding
anything to the contrary in the Plan or the provisions of such Award Agreement; 

  
 6 

 (c) To provide that such Award be assumed by the successor or survivor corporation, or a parent
or subsidiary thereof, or shall be substituted for by awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and/or applicable exercise
or purchase price, in all cases, as determined by the Administrator to provide substantially equivalent value; 
 (d) To make adjustments in
the number and type of shares of Common Stock (or other securities or property) subject to outstanding Awards and/or with respect to which Awards may be granted under the Plan (including, but not limited to, adjustments of the limitations in
Article IV hereof on the maximum number and kind of shares which may be issued) and/or in the terms and conditions of (including the grant or exercise price), and the criteria included in, outstanding Awards; provided that such adjustments
result in substantially equivalent value being provided to the holders of outstanding Awards; and/or 
 (e) To replace such Award with other
rights or property of substantially equivalent value as selected by the Administrator, and in such cases, the Administrator may provide that the Award will terminate and cannot vest, be exercised or become payable after the applicable event. 

8.3 Administrative Stand Still. In the event of any pending stock dividend, stock split, combination or exchange of shares, merger,
consolidation or other distribution (other than normal cash dividends) of Company assets to stockholders, or any other extraordinary transaction or change affecting the Shares or the share price of Common Stock, including any Equity Restructuring or
any securities offering or other similar transaction, for administrative convenience, the Administrator may refuse to permit the exercise of any Award for up to thirty days before or after such transaction. 

8.4 General. Except as expressly provided in the Plan or the Administrator’s action under the Plan, no Participant will have any
rights due to any subdivision or consolidation of Shares of any class, dividend payment, increase or decrease in the number of Shares of any class or dissolution, liquidation, merger, or consolidation of the Company or other corporation. Except as
expressly provided with respect to an Equity Restructuring under Section 8.1 above or the Administrator’s action under the Plan, no issuance by the Company of Shares of any class, or securities convertible into Shares of any class, will
affect, and no adjustment will be made regarding, the number of Shares subject to an Award or the Award’s grant or exercise price. The existence of the Plan, any Award Agreements and the Awards granted hereunder will not affect or restrict in
any way the Company’s right or power to make or authorize (i) any adjustment, recapitalization, reorganization or other change in the Company’s capital structure or its business, (ii) any merger, consolidation, dissolution or
liquidation of the Company or sale of Company assets or (iii) any sale or issuance of securities, including securities with rights superior to those of the Shares or securities convertible into or exchangeable for Shares. The Administrator may
treat Participants and Awards (or portions thereof) differently under this Article VIII. 
 ARTICLE IX. 

GENERAL PROVISIONS APPLICABLE TO AWARDS 

9.1 Transferability. Except as the Administrator may determine or provide in an Award Agreement or otherwise for Awards other than
Incentive Stock Options, Awards may not be sold, assigned, transferred, pledged or otherwise encumbered, either voluntarily or by operation of law, except by will or the laws of descent and distribution, or, subject to the Administrator’s
consent, pursuant to a domestic relations order, and, during the life of the Participant, will be exercisable only by the Participant. References to a Participant, to the extent relevant in the context, will include references to a
Participant’s authorized transferee that the Administrator specifically approves. 

  
 7 

 9.2 Documentation. Each Award will be evidenced in an Award Agreement, which may be
written or electronic, as the Administrator determines. Each Award may contain terms and conditions in addition to those set forth in the Plan. 

9.3 Discretion. Except as the Plan otherwise provides, each Award may be made alone or in addition or in relation to any other Award.
The terms of each Award to a Participant need not be identical, and the Administrator need not treat Participants or Awards (or portions thereof) uniformly. 

9.4 Termination of Status. Pursuant to the terms of the Award Agreement, the Administrator will determine how the disability, death,
retirement, authorized leave of absence or any other change or purported change in a Participant’s Service Provider status affects an Award and the extent to which, and the period during which, the Participant, the Participant’s legal
representative, conservator, guardian or Designated Beneficiary may exercise rights under the Award, if applicable. 
 9.5
Withholding. Each Participant must pay the Company, or make provision satisfactory to the Administrator for payment of, any taxes required by law to be withheld in connection with such Participant’s Awards by the date of the event
creating the tax liability. The Company may deduct an amount sufficient to satisfy such tax obligations based on the minimum statutory withholding rates (or such other rate as may be determined by the Company after considering any accounting
consequences or costs) from any payment of any kind otherwise due to a Participant. Subject to Section 10.8 and any Company insider trading policy (including blackout periods), Participants may satisfy such tax obligations (i) in cash, by
wire transfer of immediately available funds, by check made payable to the order of the Company, provided that the Company may limit the use of the foregoing payment forms if one or more of the payment forms below is permitted, (ii) to the
extent permitted by the Administrator, in whole or in part by delivery of Shares, including Shares retained from the Award creating the tax obligation, valued at their Fair Market Value, (iii) if there is a public market for Shares at the time
the tax obligations are satisfied, unless the Company otherwise determines, (A) delivery (including telephonically to the extent permitted by the Company) of an irrevocable and unconditional undertaking by a broker acceptable to the Company to
deliver promptly to the Company sufficient funds to satisfy the tax obligations, or (B) delivery by the Participant to the Company of a copy of irrevocable and unconditional instructions to a broker acceptable to the Company to deliver promptly
to the Company cash or a check sufficient to satisfy the tax withholding; provided that such amount is paid to the Company at such time as may be required by the Administrator, or (iv) to the extent permitted by the Company, any combination of
the foregoing payment forms approved by the Administrator. If any tax withholding obligation will be satisfied under clause (ii) of the immediately preceding sentence by the Company’s retention of Shares from the Award creating the tax
obligation and there is a public market for Shares at the time the tax obligation is satisfied, the Company may elect to instruct any brokerage firm determined acceptable to the Company for such purpose to sell on the applicable Participant’s
behalf some or all of the Shares retained and to remit the proceeds of the sale to the Company or its designee, and each Participant’s acceptance of an Award under the Plan will constitute the Participant’s authorization to the Company and
instruction and authorization to such brokerage firm to complete the transactions described in this sentence. 
 9.6 Amendment of Award;
Prohibition on Repricing. The Administrator may amend, modify or terminate any outstanding Award, including by substituting another Award of the same or a different type, changing the exercise or settlement date, and converting an Incentive
Stock Option to a Non-Qualified Stock Option. The Participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and
adversely affect the Participant’s rights under the Award, or (ii) the change is permitted under Article VIII or pursuant to Section 10.6. Notwithstanding the foregoing or anything in the Plan to the contrary, the Administrator may
not except pursuant to Article VIII, without the approval of the stockholders of the Company, reduce the exercise 

  
 8 

 
price per share of outstanding Options or Stock Appreciation Rights or cancel outstanding Options or Stock Appreciation Rights in exchange for cash, other Awards or Options or Stock Appreciation
Rights with an exercise price per share that is less than the exercise price per share of the original Options or Stock Appreciation Rights. 

9.7 Conditions on Delivery of Stock. The Company will not be obligated to deliver any Shares under the Plan or remove restrictions from
Shares previously delivered under the Plan until such time that (i) all Award conditions have been met or removed to the Company’s satisfaction, (ii) as determined by the Company, all other legal matters regarding the issuance and
delivery of such Shares have been satisfied, including any applicable securities laws and stock exchange or stock market rules and regulations, and (iii) the Participant has executed and delivered to the Company such representations or
agreements as the Administrator deems necessary or appropriate to satisfy any Applicable Laws. The Company’s inability to obtain authority from any regulatory body having jurisdiction, which the Administrator determines is necessary to the
lawful issuance and sale of any securities, will relieve the Company of any liability for failing to issue or sell such Shares as to which such requisite authority has not been obtained. 

9.8 Acceleration. The Administrator may provide in any Award Agreement at the time of grant or at any other time provide that any Award
will become immediately vested and fully or partially exercisable, free of some or all restrictions or conditions, or otherwise fully or partially realizable, upon a Change in Control or otherwise. 

9.9 Additional Terms of Incentive Stock Options. The Administrator may grant Incentive Stock Options only to employees of the Company,
any of its present or future parent or subsidiary corporations, as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to receive Incentive Stock Options under the Code.
If an Incentive Stock Option is granted to a Greater Than 10% Stockholder, the exercise price will not be less than 110% of the Fair Market Value on the Option’s grant date, and the term of the Option will not exceed five years. All Incentive
Stock Options will be subject to and construed consistently with Section 422 of the Code. By accepting an Incentive Stock Option, the Participant agrees to give prompt notice to the Company of dispositions or other transfers (other than in
connection with a Change in Control) of Shares acquired under the Option made within (i) two years from the grant date of the Option or (ii) one year after the transfer of such Shares to the Participant, specifying the date of the
disposition or other transfer and the amount the Participant realized, in cash, other property, assumption of indebtedness or other consideration, in such disposition or other transfer. Neither the Company nor the Administrator will be liable to a
Participant, or any other party, if an Incentive Stock Option fails or ceases to qualify as an “incentive stock option” under Section 422 of the Code. Any Incentive Stock Option or portion thereof that fails to qualify as an
“incentive stock option” under Section 422 of the Code for any reason, including becoming exercisable with respect to Shares having a fair market value exceeding the $100,000 limitation under Treasury Regulation Section 1.422-4, will be a Non-Qualified Stock Option. 

ARTICLE X. 

MISCELLANEOUS 
 10.1 No
Right to Employment or Other Status. No person will have any claim or right to be granted an Award, and the grant of an Award will not be construed as giving a Participant the right to continued employment or any other relationship with the
Company or any Subsidiary. The Company and its Subsidiaries expressly reserve the right at any time to dismiss or otherwise terminate its relationship with a Participant free from any liability or claim under the Plan or any Award, except as
expressly provided in an Award Agreement. 

  
 9 

 10.2 No Rights as Stockholder; Certificates. Subject to the Award Agreement, no
Participant or Designated Beneficiary will have any rights as a stockholder with respect to any Shares to be distributed under an Award until becoming the record holder of such Shares. Notwithstanding any other provision of the Plan, unless the
Administrator otherwise determines or Applicable Laws require, the Company will not be required to deliver to any Participant certificates evidencing Shares issued in connection with any Award and instead such Shares may be recorded in the books of
the Company (or, as applicable, its transfer agent or stock plan administrator). The Company may place legends on stock certificates issued under the Plan that the Administrator deems necessary or appropriate to comply with Applicable Laws. 

10.3 Effective Date and Term of Plan. Unless earlier terminated by the Board, the Plan will become effective upon the consummation of
the Company’s initial business combination, subject to the approval of the Company’s stockholders, and will remain in effect until the tenth anniversary of the earlier of (i) the date the Board adopted the Plan or (ii) the date
the Company’s stockholders approved the Plan, but Awards previously granted may extend beyond that date in accordance with the Plan. If the Plan is not approved by the Company’s stockholders, the Plan will not become effective and no
Awards will be granted under the Plan. 
 10.4 Amendment of Plan. The Administrator may amend, suspend or terminate the Plan at any
time; provided that no amendment, other than an increase to the Overall Share Limit, may materially and adversely affect any Award outstanding at the time of such amendment without the affected Participant’s consent. No Awards may be granted
under the Plan during any suspension period or after Plan termination. Awards outstanding at the time of any Plan suspension or termination will continue to be governed by the Plan and the Award Agreement, as in effect before such suspension or
termination. The Board will obtain stockholder approval of any Plan amendment to the extent necessary to comply with Applicable Laws. 
 10.5
Provisions for Foreign Participants. The Administrator may modify Awards granted to Participants who are foreign nationals or employed outside the United States or establish subplans or procedures under the Plan to address differences in
laws, rules, regulations or customs of such foreign jurisdictions with respect to tax, securities, currency, employee benefit or other matters. 

10.6 Section 409A. 

(a) General. The Company intends that all Awards be structured to comply with, or be exempt from, Section 409A, such that no
adverse tax consequences, interest, or penalties under Section 409A apply. Notwithstanding anything in the Plan or any Award Agreement to the contrary, the Administrator may, without a Participant’s consent, amend this Plan or Awards,
adopt policies and procedures, or take any other actions (including amendments, policies, procedures and retroactive actions) as are necessary or appropriate to preserve the intended tax treatment of Awards, including any such actions intended to
(A) exempt this Plan or any Award from Section 409A, or (B) comply with Section 409A, including regulations, guidance, compliance programs and other interpretative authority that may be issued after an Award’s grant date.
The Company makes no representations or warranties as to an Award’s tax treatment under Section 409A or otherwise. The Company and its Subsidiaries will have no obligation under this Section 10.6 or otherwise to avoid the taxes,
penalties or interest under Section 409A with respect to any Award and will have no liability to any Participant or any other person if any Award, compensation or other benefits under the Plan are determined to constitute noncompliant
“nonqualified deferred compensation” subject to taxes, penalties or interest under Section 409A. 

  
 10 

 (b) Separation from Service. If an Award constitutes “nonqualified deferred
compensation” under Section 409A, any payment or settlement of such Award upon a termination of a Participant’s Service Provider relationship will, to the extent necessary to avoid taxes under Section 409A, be made only upon the
Participant’s “separation from service” (within the meaning of Section 409A), whether such “separation from service” occurs upon or after the termination of the Participant’s Service Provider relationship. For
purposes of this Plan or any Award Agreement relating to any such payments or benefits, references to a “termination,” “termination of employment” or like terms means a “separation from service.” 

(c) Payments to Specified Employees. Notwithstanding any contrary provision in the Plan or any Award Agreement, any payment(s) of
“nonqualified deferred compensation” required to be made under an Award to a “specified employee” (as defined under Section 409A and as the Administrator determines) due to his or her “separation from service”
will, to the extent necessary to avoid taxes under Section 409A(a)(2)(B)(i) of the Code, be delayed for the six-month period immediately following such “separation from service” (or, if earlier,
until the specified employee’s death) and will instead be paid (as set forth in the Award Agreement) on the day immediately following such six-month period or as soon as administratively practicable
thereafter (without interest) but not later than 60 days following the end of such six-month period. Any payments of “nonqualified deferred compensation” under such Award payable more than six months
following the Participant’s “separation from service” will be paid at the time or times the payments are otherwise scheduled to be made. 

10.7 Limitations on Liability and Indemnification. Notwithstanding any other provisions of the Plan, no individual acting as a director,
officer, other employee or agent of the Company or any Subsidiary will be liable to any Participant, former Participant, spouse, beneficiary, or any other person for any claim, loss, liability, or expense incurred in connection with the Plan or any
Award, and such individual will not be personally liable with respect to the Plan because of any contract or other instrument executed in his or her capacity as an Administrator, director, officer, other employee or agent of the Company or any
Subsidiary. The Company will indemnify, defend and hold harmless each past or present director, officer, other employee and agent of the Company or any Subsidiary that has been or will be granted or delegated any duty or power relating to the
Plan’s administration or interpretation, against any cost or expense (including attorneys’ fees) or liability (including any sum paid in settlement of a claim with the Administrator’s approval) arising from any act or omission
concerning this Plan unless directly arising from such person’s own fraud or bad faith. This indemnification obligation of the Company shall supplement, and not supersede or replace, any other indemnification obligation, policy or agreement of
the Company covering such indemnified person. 
 10.8 Lock-Up Period. The Company may, at the
request of any underwriter representative or otherwise, in connection with registering the offering of any Company securities under the Securities Act, prohibit Participants from, directly or indirectly, selling or otherwise transferring any Shares
or other Company securities during a period of up to one hundred eighty days following the effective date of a Company registration statement filed under the Securities Act, or such longer period as determined by the underwriter. 

10.9 Data Privacy. As a condition for receiving any Award, each Participant explicitly and unambiguously consents to the collection, use
and transfer, in electronic or other form, of personal data as described in this section by and among the Company and its Subsidiaries and affiliates exclusively for implementing, administering and managing the Participant’s participation in
the Plan. The Company and its Subsidiaries and affiliates may hold certain personal information about a Participant, including the Participant’s name, address and telephone number; birthdate; social security, insurance number or other
identification number; salary; nationality; job title(s); any Shares held in the Company or its Subsidiaries and affiliates; and Award details, to implement, manage and administer the Plan and Awards (the 

  
 11 

 
“Data”). The Company and its Subsidiaries and affiliates may transfer the Data amongst themselves as necessary to implement, administer and manage a
Participant’s participation in the Plan, and the Company and its Subsidiaries and affiliates may transfer the Data to third parties assisting the Company with Plan implementation, administration and management. These recipients may be located
in the Participant’s country, or elsewhere, and the Participant’s country may have different data privacy laws and protections than the recipients’ country. By accepting an Award, each Participant authorizes such recipients to
receive, possess, use, retain and transfer the Data, in electronic or other form, to implement, administer and manage the Participant’s participation in the Plan, including any required Data transfer to a broker or other third party with whom
the Company or the Participant may elect to deposit any Shares. The Data related to a Participant will be held only as long as necessary to implement, administer, and manage the Participant’s participation in the Plan. A Participant may, at any
time, view the Data that the Company holds regarding such Participant, request additional information about the storage and processing of the Data regarding such Participant, recommend any necessary corrections to the Data regarding the Participant
or refuse or withdraw the consents in this Section 10.9 in writing, without cost, by contacting the local human resources representative. If the Participant refuses or withdraws the consents in this Section 10.9, in the
Administrator’s discretion, the Company may cancel the Participant’s ability to participate in the Plan. For more information on the consequences of refusing or withdrawing consent, Participants may contact their local human resources
representative. 
 10.10 Severability. If any portion of the Plan or any action taken under it is held illegal or invalid for any
reason, the illegality or invalidity will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as if the illegal or invalid provisions had been excluded, and the illegal or invalid action will be null and void.

 10.11 Governing Documents. If any contradiction occurs between the Plan and any Award Agreement or other written agreement between
a Participant and the Company (or any Subsidiary) that the Administrator has approved, the Plan will govern, unless it is expressly specified in such Award Agreement or other written document that a specific provision of the Plan will not apply.

 10.12 Governing Law. The Plan and all Awards will be governed by and interpreted in accordance with the laws of the State of
Delaware, disregarding any state’s choice-of-law principles requiring the application of a jurisdiction’s laws other than the State of Delaware. 

10.13 Claw-back Provisions. All Awards (including any proceeds, gains or other economic benefit the Participant actually or
constructively receives upon receipt or exercise of any Award or the receipt or resale of any Shares underlying the Award) will be subject to any Company claw-back policy, including any claw-back policy adopted to comply with Applicable Laws
(including the Dodd-Frank Wall Street Reform and Consumer Protection Act and any rules or regulations promulgated thereunder) as set forth in such claw-back policy or the Award Agreement. 

10.14 Titles and Headings. The titles and headings in the Plan are for convenience of reference only and, if any conflict, the
Plan’s text, rather than such titles or headings, will control. 
 10.15 Conformity to Securities Laws. Participant acknowledges
that the Plan is intended to conform to the extent necessary with Applicable Laws. Notwithstanding anything herein to the contrary, the Plan and all Awards will be administered only in conformance with Applicable Laws. To the extent Applicable Laws
permit, the Plan and all Award Agreements will be deemed amended as necessary to conform to Applicable Laws. 
 10.16 Relationship to
Other Benefits. No payment under the Plan will be taken into account in determining any benefits under any pension, retirement, savings, profit sharing, group insurance, welfare or other benefit plan of the Company or any Subsidiary except as
expressly provided in writing in such other plan or an agreement thereunder. 

  
 12 

 10.17 Broker-Assisted Sales. In the event of a broker-assisted sale of Shares in
connection with the payment of amounts owed by a Participant under or with respect to the Plan or Awards, including amounts to be paid under the final sentence of Section 9.5: (a) any Shares to be sold through the broker-assisted sale will be
sold on the day the payment first becomes due, or as soon thereafter as practicable; (b) such Shares may be sold as part of a block trade with other Participants in the Plan in which all participants receive an average price; (c) the
applicable Participant will be responsible for all broker’s fees and other costs of sale, and by accepting an Award, each Participant agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses relating to any
such sale; (d) to the extent the Company or its designee receives proceeds of such sale that exceed the amount owed, the Company will pay such excess in cash to the applicable Participant as soon as reasonably practicable; (e) the Company
and its designees are under no obligation to arrange for such sale at any particular price; and (f) in the event the proceeds of such sale are insufficient to satisfy the Participant’s applicable obligation, the Participant may be required
to pay immediately upon demand to the Company or its designee an amount in cash sufficient to satisfy any remaining portion of the Participant’s obligation. 

10.18 No Fractional Shares. Notwithstanding any provision in the Plan to the contrary, no fractional Shares shall be issued or delivered
pursuant to the Plan or any Award, and the Administrator shall determine whether cash, other securities or other property shall be paid or transferred in lieu of any fractional Shares, or whether such fractional Shares or any rights thereto shall be
canceled, terminated or otherwise eliminated. 
 10.19 Section 83(b) Elections Prohibited. No Participant may make an election under
Section 83(b) of the Code, or any successor section thereto, with respect to any Award without the consent of the Administrator, which the Administrator may grant or withhold in its discretion.

Company or any of its Subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, the Company) directly or indirectly acquires beneficial ownership (within

held in the Company prior to the consummation of the transaction. 
 Notwithstanding the foregoing, in no event shall the Company’s
initial business combination or the transactions occurring in connection therewith constitute a Change in Control and, if a Change in Control constitutes a payment event with respect to any Award (or portion of any Award) that provides for the
deferral of compensation that is subject to Section 409A, to the extent required to avoid the imposition of additional taxes under Section 409A, the transaction or event described in subsection (a), (b) or (c) with respect to
such Award (or portion thereof) shall only constitute a Change in Control for purposes of the payment timing of such Award if such transaction also constitutes a “change in control event,” as defined in Treasury Regulation Section 1.409A-3(i)(5).

exercised in its discretion, to determine conclusively whether a Change in Control has occurred pursuant to the above definition, the date of the occurrence of such Change in Control and any incidental matters relating thereto; provided that any

Committee will be, at the time the Committee takes any action with respect to an Award that is subject to Rule 16b-3, a “non-employee director” within the
meaning of Rule 16b-3; however, a Committee member’s failure to qualify as a “non-employee director” within the meaning of Rule 16b-3 will not invalidate any Award granted by the Committee that is otherwise validly granted under the Plan. 

11.10 “Common Stock” means the Class A common stock of the Company, $.0001 par value per Share, and any class of
common stock into which such common shares may hereafter be converted, reclassified or recapitalized.

or indirectly promote or maintain a market for the Company’s securities; and (iii) is a natural person. 

  
 15 

 11.13 “Designated Beneficiary” means the beneficiary or beneficiaries the
Participant designates, in a manner the Administrator determines, to receive amounts due or exercise the Participant’s rights if the Participant dies. Without a Participant’s effective designation, “Designated Beneficiary” will

Subsidiaries within the meaning of Section 3401(c) of the Code including, without limitation, officers who are members of the Board. 

11.18 “Equity Restructuring” means a nonreciprocal transaction between the Company and its stockholders, such as a
stock dividend, stock split, spin-off or recapitalization through a large, nonrecurring cash dividend, that affects the number or kind of Shares (or other Company securities) or the share price of Common Stock
(or other Company securities) and causes a change in the per share value of the Common Stock underlying outstanding Awards. 
 11.19
“Exchange Act” means the Securities Exchange Act of 1934, as amended. 
 11.20 “Fair Market
Value” means, as of any date, the value of Common Stock determined as follows: (i) if the Common Stock is listed on any established stock exchange, its Fair Market Value will be the closing sales price for such Common Stock as
