 (ii) (A) counsel for the Employee Stockholder (which counsel shall be reasonably acceptable to the Company) shall have furnished the Company with an opinion or other advice, reasonably satisfactory in

other advice reasonably satisfactory in form and substance to the Company to the effect that such transfer will comply with the securities laws of such jurisdiction. 
 Notwithstanding the foregoing, the Company acknowledges and agrees that any of the following transfers of Stock are deemed to be in compliance with the Act and this Agreement (including without limitation
any restrictions or prohibitions herein), and no opinion of counsel is required in connection therewith: (1) a transfer made pursuant to Sections 3 (including transfers in a Proposed Sale (as defined in the Sale Participation Agreement)

Stockholder agrees that, if any shares of the Stock are offered to the public pursuant to an effective registration statement under the Act (other than registration of securities issued on Form S-8, S-4 or any successor or similar form), the
Employee Stockholder will not effect any public sale or distribution of any shares of the Stock not covered by such registration statement, including a sale pursuant to Rule 144 or any swap or other economic arrangement that transfers to another
Person any of the economic consequences of owning the Stock, from the time of the receipt of a notice from the Company that the Company has filed or imminently intends to file such registration statement until (i) 180 days (or such shorter
period as may be (A) consented to by the managing underwriter or underwriters or (B) applicable to the Investors, subject to the determination of the managing underwriter or underwriters that providing such shorter period to the Employee

(y) applicable to the Investors, subject to the determination of the managing underwriter or underwriters that providing such shorter period to the Employee Stockholder pursuant this clause (y) would not adversely affect the success of
such offering) in the case of any other Public Offering after the date of the prospectus (or prospectus supplement if the offering is made pursuant to a “shelf” registration) pursuant to which such Public Offering shall be made, unless
otherwise agreed to in writing by the Company. 
 (f) The Employee Stockholder represents and warrants that (i) with respect

(a) The Employee Stockholder agrees that he or she will not transfer any shares of Stock at any time without the consent of the Investors;
provided, however, that the Employee Stockholder may transfer shares of Stock pursuant to one of the following exceptions: (i) transfers permitted by Sections 4 or 5; (ii) transfers permitted by clauses (2), (3) and (4) of

and from time to time, waive in writing the restrictions on transfers contained in Section 3(a), whether such waiver is made prior to or after the transferee has effected or committed to effect the transfer, or has notified the Investors of
such transfer or commitment to transfer. Any transfers made pursuant to such waiver or which are later made subject to such a waiver shall, as of the date of the waiver and at all times thereafter, not be deemed to violate any applicable
restrictions on transfers contained in this Agreement.

to the Company. 
 (a) Except as otherwise provided herein, if the Employee Stockholder’s employment with the Company
Group terminates as a result of the death or Disability of the Employee Stockholder, then the applicable Employee Stockholder Entity, shall, for 365 days (the “4(a) Put Period”) following the date of such termination for death or
Disability, have the right to: 
 (i) with respect to Stock, sell to the Company, and the Company shall be
required to purchase, on one occasion, all of the shares of Stock then held by the applicable Employee Stockholder Entities at a per share price equal to Fair Market Value on the Repurchase Calculation Date (the “Section 4 Repurchase
Price”); and 
 (ii) with respect to any outstanding vested Options, sell to the Company, and the
Company shall be required to purchase, on one occasion, all of the

Price of each Option for all of the Exercisable Option Shares, which Options shall be terminated in exchange for such payment. In the event the Employee Stockholder Entity elects to sell under this Section 4(a)(ii) and the foregoing Option
Excess Price on a vested Option is zero or a negative number, such outstanding exercisable Option granted to the Employee Stockholder shall be automatically terminated without any payment in respect thereof. In addition, and for the avoidance of
doubt, all unvested Options shall be terminated and cancelled without any payment therefor as of the date specified by the Award Agreement in the event of the Employee Stockholder’s death or Disability. 

(b) Except as otherwise provided herein, if the Employee Stockholder owns Purchased Stock and the Employee Stockholder’s employment
with the Company Group terminates as a result of a Section 5(b) Call Event prior to the fourth anniversary of the Closing Date, then the applicable Employee Stockholder shall, for ninety (90) days (the “4(b) Put Period”)

occasion, all of the shares of such Stock then held by the applicable Employee Stockholder at a per share price equal to the Section 4 Repurchase Price. 
 (c) Except as otherwise provided herein, if the Employee Stockholder owns Purchased Stock and the Employee Stockholder’s employment with the Company Group terminates prior to the fourth anniversary
of the Closing Date as a result of any reason other than a Section 5(b) Call Event or for death or Disability, then the applicable Employee Stockholder shall, for ninety (90) days (the “4(c) Put Period”) following the
earlier to occur of (i) notice from the Company to the Employee Stockholder that the Company will not exercise its rights pursuant to Section 5(e) as to any portion of Purchased Stock and (ii) the expiration of the period in which the
Company must provide a Repurchase Notice to the Employee Stockholder pursuant to Section 5(e) have the right to, with respect to Purchased Stock, sell to the Company, and the Company shall be required to purchase, on one occasion, all of the
shares of such Stock then held by the applicable Employee Stockholder at a per share purchase price equal to the lesser of (x) the Base Price and (y) the Fair Market Value on the Repurchase Calculation Date. 

(d) In the event the applicable Employee Stockholder Entities intend to exercise their rights pursuant to Section 4(a)-(c), such
Employee Stockholder Entities shall send written notice to the Company, at any time during the 4(a) Put Period, 4(b) Put Period or 4(c) Put Period (each, a “Put Period”), as applicable, of their intention to sell shares of Stock in
exchange for the payment referred to in the applicable subsection of Section 4(a)(i) and shall indicate the number of shares of Stock to be sold and, for purposes of Section 4(a), the number of Options (based on the number of Exercisable
Option Shares) to be sold with payment in respect thereof (the “Redemption Notice”). The completion of the purchases shall take place at the principal office of the Company on no later than the twentieth business day (such date to
be determined by the Company) after the giving of the Redemption Notice. The applicable Repurchase Price 

  
 6 

 
(including any payment with respect to the Options as described above) shall be paid by delivery to the applicable Employee Stockholder Entities, at the option of the Company, of a certified bank
check or checks in the appropriate amount payable to the order of each of the applicable Employee Stockholder Entities (or by wire transfer of immediately available funds, if the Employee Stockholder Entities provide to the Company wire transfer
instructions) against delivery of certificates or other instruments representing the Stock so purchased and appropriate documents cancelling the Options so terminated appropriately endorsed or executed by the applicable Employee Stockholder Entities
or any duly authorized representative. Notwithstanding anything in this Section 4(d), in the event the Company receives a Redemption Notice at a time when the Fair Market Value is equal to or less than the applicable Option Exercise Price, the
Company shall provide the Employee Stockholder Entity that delivered the Redemption Notice to the Company with a statement of valuation and a request that the applicable Employee Stockholder Entity resubmit the Redemption Notice in order to confirm
its desire to exercise its rights hereunder with respect to any vested Options. 
 (e) Notwithstanding anything in this
Section 4 to the contrary, if there exists and is continuing a default or an event of default on the part of the Company Group under any loan, guarantee or other agreement under which any part of the Company Group has borrowed money or if any
repurchase under this Section 4(a) or Section 5 below, as the case may be, would result in a default or an event of default on such part of the Company Group under any such agreement or if a repurchase by the Company would reasonably be
expected to be prohibited by the Delaware General Corporation Law or any federal or state securities laws or regulations (or if the Company reincorporates in another state, the business corporation law of such state) (each such occurrence being an
“Event”), the Company shall not be obligated to repurchase any of the Stock or the Options from the applicable Employee Stockholder Entities to the extent it would cause any such default or would be so prohibited by the Event for
cash but instead, with respect to such portion with respect to which cash settlement is prohibited, may satisfy its obligations with respect to the Employee Stockholder Entities’ exercise of their rights under the applicable subsection of this
Section 4 by delivering to the applicable Employee Stockholder Entity a note with a principal amount equal to the amount payable under this Section 4 that was not paid in cash, having terms acceptable to such part of the Company
Group’s lenders and permitted under such part of the Company Group’s debt instruments but which in any event (i) shall be mandatorily repayable promptly and to the extent that an Event no longer prohibits the payment of cash to the
applicable Employee Stockholder Entity pursuant to this Agreement; and (ii) shall bear interest at a rate equal to the effective rate of interest in respect of the senior notes issued by such part of the Company Group. In such cases, the Put
Period shall be tolled for so long as an Event shall continue. Notwithstanding the foregoing and subject to Section 4(l), if an Event exists and is continuing for one hundred and eighty (180) days after the date of the Redemption Notice,
the Employee Stockholder Entities shall be permitted by written notice to rescind (with the ability to reissue at any time during the Put Period) any Redemption Notice with respect to that portion of the Stock and Options repurchased by the Company
from the Employee Stockholder Entities pursuant to this Section 4 with the note described in the foregoing sentence, and such repurchase shall be rescinded; provided that, upon such rescission, such note shall be immediately canceled
without any action on the part of the Company or the Employee Stockholder Entities, and notwithstanding anything herein or in such note to the contrary, the Company shall have no obligation to pay any amounts of principal or interest thereunder.

 (f) During the first twenty days of the calendar month of January (the “Election
Period”) of each calendar year beginning 2016 and thereafter, each Employee Stockholder that is employed by the Company Group through the end of such Election Period and each Employee Stockholder whose employment with the Company Group was
terminated due to a Section 5(b) Call Event or Section 5(d)(ii) Call Event prior to the end of the Election Period (each such Employee Stockholder, an “Option Eligible Stockholder”), shall have the right, upon irrevocable
notice given to the Company on or prior to 4:00 p.m. Central Standard Time of the last business day of the Election Period, to offer to sell to the Company, and the Company shall be required to purchase (subject to Sections 4(h), 4(i), 4(j), 4(k)
and 4(l)), all or any portion of the Option Stock, including Stock that would be issued pursuant to exercise by the Employee Stockholder of any vested and excisable Options during the Election Period, as designated by such Option Eligible
Stockholder in such notice and not to exceed an amount of Option Stock attributable to 25% of the combined amount of Employee Stockholder’s Options granted pursuant to the Option Plan, both vested and unvested, and previously exercised,
Options, which such notice shall not be effective with respect to any amount of unexercised options included in the notice. To assist the Option Eligible Stockholders in making the determination of whether or not to exercise any of their rights
described in this Section 4(f) or Sections 4(g), 4(h), 4(i) and 4(j) below, during any Election Period, the Company will be required to provide each Option Eligible Stockholder with the Fair Market Value as of December 31 of the prior year
by no later than the tenth day of January. The Election Period for an Option Eligible Stockholder will be extended by the number of business days that the Company may be late in delivering the notice of Fair Market Value to such Option Eligible
Stockholder. 
 (g) During the Election Period of each calendar year beginning 2016 and thereafter, each Employee Stockholder
that is employed by the Company Group through the end of such Election Period and each Employee Stockholder whose employment with the Company Group was terminated due to a Section 5(b) Call Event or Section 5(d)(ii) Call Event prior to the
end of the Election Period (each such Employee Stockholder, a “Purchased Stock Eligible Stockholder”), shall have the right, upon irrevocable notice given to the Company on or prior to 4:00 p.m. Central Standard Time of the last
business day of the Election Period, to offer to sell to the Company, and the Company shall be required to purchase (subject to Sections 4(h), 4(i), 4(j), 4(k) and 4(l)), all or any portion of up to 100% of the Purchased Stock of such Purchased
Stock Eligible Stockholder as designated by such Purchased Stock Eligible Stockholder in such notice. For the purposes of this Section 4 (including, without limitation, Sections 4(h), 4(i), 4(j), 4(k) and 4(l)), any Option Stock held for at
least six months after the exercise of the applicable Option by an Option Eligible Stockholder shall be deemed to be “Purchased Stock” and may be included in the notice delivered pursuant to this Section 4(g). 

(h) In respect of all Option Eligible Stockholders and Purchased Stock Eligible Stockholders who have duly exercised his or her rights in
accordance with Section 4(f) and Section 4(g) (respectively, the “Option Stockholders” and the “Purchased Stock Stockholders”) the Company shall tabulate the number of shares of Purchased Stock and the
number of shares of Option Stock that the Employee Stockholders and any other employees with similar rights have elected to offer to sell to the Company and calculate (i) the aggregate amount of the Fair Market Value (as of December 31 of
the calendar year immediately prior to the applicable Election Period) of the Purchased Stock so offered (the “Purchased Stock Amount”) and (ii) the aggregate amount of the Fair Market Value (as of December 31 of the
calendar year immediately prior to the applicable Election Period) of the Option Stock so offered (the “Option Amount”). 

  
 8 

 (i) If the Purchased Stock Amount exceeds $50,000,000 during any calendar
year, then the Company shall repurchase on a pro rata basis (in respect of the amount of Purchased Stock offered by each Purchased Stock Stockholder) from all Purchased Stock Stockholders an amount of Purchased Stock with a Fair Market Value (as of
December 31 of the calendar year immediately prior to the applicable Election Period) equal in the aggregate to $50,000,000 and the Company shall not repurchase any Option Stock from the Option Stockholders. 

(ii) If the Purchased Stock Amount is less than $50,000,000 but the aggregate Purchased Stock Amount and Option Amount is
more than $50,000,000 during any calendar year, then the Company shall repurchase all Purchased Stock offered by the Purchased Stock Stockholders at its Fair Market Value (as of December 31 of the calendar year immediately prior to the
applicable Election Period) (in the aggregate, the “Exercised Purchased Stock Amount”), and shall, subject to final determination of the Revised Option Amount pursuant to Section 4(j), indicate its intention to repurchase on a
pro rata basis (in respect of the amount of Option Stock offered by each Option Stockholder) from all Option Stockholders an amount of Option Stock with a Fair Market Value (as of December 31 of the calendar year immediately prior to the
applicable Election Period) equal in the aggregate to the difference between $50,000,000 minus the Exercised Purchased Stock Amount (subject to the redetermination of the Option Amount set forth in Section 4(j) below). 

(iii) If the aggregate Purchased Stock Amount and Option Amount is less than $50,000,000 during any calendar year, then
the Company shall, subject to final determination of the Revised Option Amount pursuant to Section 4(j), repurchase all Purchased Stock and Option Stock offered by the Employee Stockholders during the applicable Election Period. 

(iv) In the event that any Employee Stockholder has been prevented pursuant to this Section 4(h) from selling all of
the Purchased Stock or Option Stock that the Employee Stockholder tendered to the Company in any calendar year (such unrepurchased amount, the “Shortfall Amount”), such Employee Stockholder shall have priority to resell his Stock to
the extent of the Shortfall Amount (on a pari passu basis with any other Employee Stockholders so prevented) during the calendar year immediately following; provided that this priority shall first be applied to the Shortfall Amount in respect of
Purchased Stock and then to the Shortfall Amount in respect of Option Stock, and on a pro rata basis among all subject Employee Stockholders in the event that this Section 4(h) does not permit the purchase of the entire Shortfall Amount in
respect of the Purchased Stock or the Option Stock in a given calendar year; and further provided that any Shortfall Amount in respect of a given calendar year cannot be repurchased due to the operation of this Section 4(h), such remaining
shortfall amount shall have priority over any Shortfall Amounts in respect of subsequent calendar years. 

  
 9 

 (i) On or before February 15 of the calendar year of the applicable Election Period,
the Company shall notify each Purchased Stock Stockholder of the amount of Purchased Stock that the Company will repurchase pursuant to Section 4(h) above and each Option Stockholder of the amount of Option Stock (if any) that the Company would
be able to repurchase pursuant to Section 4(h) above based on the Fair Market Value as of December 31 of the immediately preceding calendar year (subject to the redetermination of the Option Amount set forth in Section 4(j) below).
The repurchase of Purchased Stock from each Purchased Stock Stockholder will occur as promptly as practicable after such date, subject to the delivery to the Company by the Purchased Stock Stockholder of the required documentation described in
Section 4(k) below. 
 (j) On July 21, or if July 21 is not a business day, the first business day thereafter, of
the calendar year of the applicable Election Period, the Company shall recalculate the aggregate amount of the Fair Market Value (as of such date) of the Option Stock offered pursuant to Section 4(h) above (the “Revised Option
Amount”), and notify each Option Stockholder within five business days of such calculation of (i) the change in Fair Market Value since December 31 of the immediately preceding calendar year and (ii) the amount of Option
Stock that the Company will repurchase pursuant to Section 4(h) above, which such amount may be less than the amount previously notified to the Option Stockholder in the event that Section 4(h)(ii) above applies and there has been an
increase in Fair Market Value. Each Employee Stockholder will have five business days following such notification to elect to revoke his offer to sell the designated amount of Option Stock (whether the Fair Market Value has increased, decreased or
remained unchanged) and, following the lapse of such five-day period, the Company shall redetermine the Revised Option Amount taking into account any such revocations, and thereafter the Revised Option Amount shall be deemed to be equal to such
redetermined amount. If the aggregate Purchased Stock Amount and Revised Option Amount is less than $50,000,000 during the applicable calendar year, then the Company shall repurchase all Option Stock offered by the Option Stockholders during the
applicable Election Period. If the Purchased Stock Amount is less than $50,000,000 but the aggregate Purchased Stock Amount and Revised Option Amount is more than $50,000,000, the Company shall repurchase on a pro rata basis (in respect of the
amount of Option Stock offered by each Option Stockholder that has not delivered a notice of revocation to the Company) an amount of Option Stock with a Fair Market Value equal in the aggregate to the difference between $50,000,000 minus the
Exercised Purchased Stock Amount. The repurchase of Option Stock from each Option Stockholder will occur as promptly as practicable after such redetermination, subject to the delivery to the Company by the Option Stockholder of the required
documentation described in Section 4(k) below. 
 (k) The applicable Repurchase Price shall be paid by delivery to the
applicable Employee Stockholder Entities, at the option of the Company, of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Employee Stockholder Entities (or by wire transfer of immediately
available funds, if the Employee Stockholder Entities provide to the Company wire transfer instructions) against delivery of certificates, if any where given to the Employee Stockholder, or other reasonable documents or instruments representing the
Stock so purchased and reasonable documents or instruments cancelling the Options so terminated appropriately endorsed or executed by the applicable Employee Stockholder Entities or any duly authorized representative.

  
 10 

 
Notwithstanding anything to the contrary in this Agreement, if any part of the Company Group has taken any action that, together with the repurchase of $50,000,000 of Stock pursuant to
Section 4(h) above, would constitute an Event under any loan, guarantee or other agreement under which any part of the Company Group has borrowed money, the references in this Section 4 to “$50,000,000” shall be deemed to be the
maximum possible amount that, together with such other actions, would not constitute an Event (but, for the avoidance of doubt, in no event shall such amount ever be under any circumstances greater than $50,000,000). 

In the event that all applicable loans, guarantees and other agreements under which any part of the Company Group has borrowed money
permit the repurchase of equity interests of the Company in excess of $50,000,000 during any calendar year, the board of directors of the Company (or the applicable committee thereof) shall in their discretion have the ability to cause the
references in this Section 4 to “$50,000,000” to be deemed to be an amount in excess of $50,000,000, up to a total of $75,000,000, so long as such amount would not constitute an Event as described above. 

(l) Notwithstanding anything in this Agreement to the contrary, except for any payment obligation of the Company which has arisen prior to
the occurrence of a Lapse Date, Section 4 shall terminate and be of no further force or effect upon the occurrence of such Lapse Date. 
  

	 	5.	The Company’s Option to Purchase Stock and Options of the Employee Stockholder Upon Certain Terminations of Employment. 

(a) Termination for Cause by the Company and Breach of Transfer Restrictions. If, (i) the Employee Stockholder’s active
employment with the Company Group is terminated by the Company Group for Cause or (ii) the Employee Stockholder Entities effect a transfer of Stock (or Options) that is prohibited under this Agreement (or the Award Agreements, as applicable),
after notice from the Company of such impermissible transfer and a reasonable opportunity to cure such transfer which is not so cured (each event described above, a “Section 5(a) Call Event”), then: 

(i) with respect to all Options, all outstanding Options (whether vested or unvested) shall be automatically terminated
without any payment in respect thereof upon the occurrence of the Section 5(b) Call Event; and 
 (ii) with
respect to any Stock, the Company may purchase, on one occasion, all or any portion of the shares of such Stock then held by the applicable Employee Stockholder Entities at a per share purchase price equal to the lesser of (x) the Base Price
and (y) the Fair Market Value on the Repurchase Calculation Date. 
 (b) Termination without Cause by the Company and
Termination by the Employee Stockholder with Good Reason. If the Employee Stockholder’s active employment with the Company Group is terminated (i) by the Company (or, if applicable, its subsidiaries or Affiliates) without Cause (other
than due to his or her death or Disability) or (ii) by the Employee Stockholder with Good Reason (each, a “Section 5(b) Call Event”) then: 

  
 11 

 (i) with respect to Stock, the Company may purchase all or any portion of
the shares of such Stock then held by the applicable Employee Stockholder Entities at a per share purchase price equal to the greater of (x) the Base Price and (y) the Fair Market Value on the Repurchase Calculation Date; 

(ii) with respect to any outstanding vested Options, the Company may purchase, on one occasion, all or any portion of the
exercisable vested Options held by the applicable Employee Stockholder Entities for an amount equal to the sum of the excess, if any, of the Fair Market Value on the Repurchase Calculation Date over the Option Exercise Price of each Option for all
of the Exercisable Option Shares (solely relating to the vested Options being purchased by the Company hereunder), which vested Options shall be terminated in exchange for such payment. In the event the Company elects to repurchase under this
Section 5(b)(ii) and the foregoing Option Excess Price on a vested Option is zero or a negative number, such outstanding exercisable vested Option shall be automatically terminated without any payment in respect thereof; and 

(iii) with respect to unvested Options, all outstanding unvested Options shall automatically be terminated without any
payment in respect thereof as of the applicable date specified by the Award Agreement in the case of a termination by the Company Group without Cause (other than due to his or her death or Disability) or a termination by the Employee Stockholder
with Good Reason. 
 (c) Termination Due to Death or Disability. If the Employee Stockholder’s active employment with
the Company Group is terminated due to his or her death or Disability (each, a “Section 5(c) Call Event”) then: 
 (i) with respect to any Stock acquired by the Employee Stockholder through the exercise of vested Options, the Company may purchase all or any portion of the shares of such Stock then held by the
applicable Employee Stockholder Entities at a per share purchase price equal to Fair Market Value on the Repurchase Calculation Date; 
 (ii) with respect to any outstanding Options, the Company may purchase, on one occasion, all or any portion of the exercisable vested Options held by the applicable Employee Stockholder Entities for an
amount equal to the sum of the excess, if any, of the Fair Market Value on the Repurchase Calculation Date over the Option Exercise Price of each Option for all of the Exercisable Option Shares (solely relating to the vested Options being purchased
by the Company hereunder), which vested Options shall be terminated in exchange for such payment. In the event the Company elects to repurchase under this Section 5(c)(ii) and the foregoing Option Excess Price on a vested Option is zero or a
negative number, such outstanding exercisable vested Option shall be automatically terminated without any payment in respect thereof; and 
 (iii) with respect to unvested Options, all outstanding unvested Options shall automatically be terminated without any payment in respect thereof as of the date specified by the Award Agreement in the
event of the Employee Stockholder’s death or Disability. 

  
 12 

 For the avoidance of doubt, at no time shall the Company have the right, due to the Employee
Stockholder’s death or Disability, to cause the Employee Stockholder Entities without their consent to sell to the Company any Purchased Stock. 
 (d) Termination by the Employee Stockholder Without Good Reason. If the Employee Stockholder’s active employment with the Company Group is terminated by the Employee Stockholder without Good
Reason (excluding due to his or her death or Disability): 
 (i) Before June 21, 2015 (a “Section
5(d)(i) Call Event”): 
 (A) With respect to any Purchased Stock, the Company may purchase all or any
portion of the shares of such Purchased Stock then held by the Employee Stockholder Entities on the date of such termination of employment at a per share purchase price equal to the lesser of (x) the Base Price and (y) the Fair Market
Value on the Repurchase Calculation Date; and 
 (B) With respect to any outstanding Options, whether vested or
unvested, all such outstanding Options shall be terminated on the date specified by the Award Agreement without any payment in respect thereof; provided, however, that with respect to any Option Stock acquired upon exercise of vested Options, the
Company can purchase all or any portion of the shares of such Option Stock then held by the Employee Stockholder Entities on the date of such termination of employment at the lesser of (x) the Option Exercise Price or (y) the Fair Market
Value on the Repurchase Calculation Date. 
 (ii) On or after June 21, 2015 (a
“Section 5(d)(ii) Call Event”): 
 (A) With respect to any Purchased Stock and any Option
Stock acquired upon exercise of vested Options, the Company may purchase all or any portion of the shares of such Purchased or Option Stock then held by the Employee Stockholder Entities on the date of such termination of employment at a per share
purchase price equal to the Fair Market Value on the Repurchase Calculation Date, and 
 (B) With respect to any
vested Options, the Company may purchase all or any portion of the shares of such vested Options then held by the Employee Stockholder Entities for an amount equal to the sum of the excess, if any, of the Fair Market Value on the Repurchase
Calculation Date over the Option Exercise Price of each Option for all of the Exercisable Option Shares (solely relating to the vested Options being purchased by the Company), in each case of the foregoing which vested Options shall be terminated in
exchange for such payment. In the event the Company elects to repurchase under this Section 5(d)(ii)(B) and the foregoing Option Excess Price on a vested Option is zero or a negative number, such outstanding vested Option shall be automatically
terminated without any payment in respect thereof. 
 (e) Call Notice. The Company shall have a period (the “Call
Period”) of one hundred eighty (180) days from the date of any Call Event (or, if later, with respect to a Section 

  
 13 

 
5(a) Call Event, the date after discovery of, and the applicable cure period for, an impermissible transfer constituting a Section 5(a) Call Event) in which to give notice in writing to the
Employee Stockholder of its election to exercise its rights and obligations pursuant to this Section 5 (“Repurchase Notice”); provided, however, that upon the occurrence of any Call Event, the Company shall advise the
Employee Stockholder Entities as to whether it intends to deliver Repurchase Notice, whether the purchase price will be less than the Fair Market Value, and in respect of which Options or Stock, within thirty (30) days following the date of
such Call Event. Notwithstanding the foregoing, the Company reserves the right to extend the Call Period to ensure that the Employee Stockholder Entities are able to comply with the one hundred and eighty (180) day stock ownership holding
period identified in Section 5(f) below, but which shall in no event extend beyond thirty (30) days after the date that such one hundred and eighty (180) day holding period expires. The completion of the purchases pursuant to the
foregoing shall take place at the principal office of the Company no later than the fifteenth business day after the giving of the Repurchase Notice. The applicable Repurchase Price (including any payment with respect to the Options as described in
this Section 5) shall be paid by delivery to the applicable Employee Stockholder Entities of a certified bank check or checks in the appropriate amount payable to the order of each of the applicable Employee Stockholder Entities (or by wire
transfer of immediately available funds, if the Employee Stockholder Entities provide to the Company wire transfer instructions) against delivery of certificates or other instruments representing the Stock so purchased and appropriate documents
canceling the Options so terminated, appropriately endorsed or executed by the applicable Employee Stockholder Entities or any duly authorized representative, if such Stock or Options are held in certificated form. For the avoidance of doubt, in the
event that the Company does not exercise its rights pursuant to this Section 5(e) as to any Stock, either Purchased Stock or Option Stock, the Employee Stockholder Entities’ ownership of and rights in such Stock shall not be affected.

 (f) Use of Note to Satisfy Call Payment; Termination of Call Right. Notwithstanding any other provision of this
Section 5 to the contrary, if there exists and is continuing any Event, the Company will, to the extent it has exercised its rights to purchase Stock or Options pursuant to this Section 5, in order to complete the purchase of any Stock or
Options pursuant to this Section 5, deliver to the applicable Employee Stockholder Entities (i) a cash payment for any amounts payable pursuant to this Section 5 that would not cause an Event and (ii) a note having the same terms
as that provided in Section 4(e) above with a principal amount equal to the amount payable but not paid in cash pursuant to this Section 5 due to the Event. Notwithstanding the foregoing, if an Event exists and is continuing for one
hundred and eighty (180) days from the date of the Call Event, the proposed repurchase of that portion of the Stock and Options to be repurchased by the Company from the Employee Stockholder Entities pursuant to this Section 5 with the
note described in the foregoing sentence shall immediately terminate, the Stock or Options shall be returned to the Employee Stockholder and the Company shall have no further rights or obligations under this Section 5. The occurrence of an
Event shall toll, for any Options or Stock called pursuant to this Section 5, any time period requirements for (x) exercise by the Employee Stockholder or (y) for their termination. 

(g) Section 5(b) Call Event True-Up Payment. In addition, in the event of a Section 5(b) Call Event within one-hundred
eighty (180) days immediately preceding an Initial Public Offering or a Change of Control transaction whereby the Company exercises its right to purchase such Employee Stockholder’s shares of Common Stock and Options and the per share

  
 14 

 
consideration paid for one share of Common Stock in such transaction (the “IPO/CoC Price”) is greater than the Fair Market Value paid upon the Company’s exercise of its
right to purchase such Stock and Options (the “Call FMV”), then within ten (10) business days following the consummation of such Initial Public Offering or Change of Control transaction, the Company shall pay the terminated
Employee Stockholder an amount equal to the product of (x) the excess of the IPO/CoC Price over the Call FMV and (y) the aggregate of the number of shares of Common Stock, and the number of shares subject to the vested Options, in each
case that were purchased by the Company in connection with its exercise of its rights under Section 5(b) of this Agreement. 

(h) Expiration of this Section 5; Company’s Election. Notwithstanding anything in this Agreement to the contrary, except
for any payment obligation of the Company which has arisen prior to the occurrence of a Lapse Date, this Section 5 shall terminate and be of no further force or effect upon the occurrence of such Lapse Date. The Company may only exercise its
call option pursuant to a Call Event for one hundred and eighty (180) days after such event. The rights of the Company set forth in this Section 5 are exercisable in the sole discretion of the Company, and the Employee Stockholder
acknowledges and agrees that the Company is under no obligation to, and may determine not to elect to, exercise such rights. 

(i) Effect of Accounting Principles. Notwithstanding anything set forth in Section 4 or 5 to the contrary, in the event that
it is determined by the Board, after consultation with the Chief Financial Officer of the Company, that any of the provisions of either of Section 4 or 5 would result in any of the Options being classified as a liability as contemplated by
Financial Accounting Standards Board Accounting Standard Codification (ASC) Section 718, Compensation — Stock Compensation (FASB ASC 718), including any amendments and interpretations thereto, then the Company shall be required to
advise the Employee Stockholder Entities of this determination (x) in order to allow the Employee Stockholder Entities to exercise their rights under Section 4 and (y) in order for the Company to exercise its rights under
Section 5 (but only to the extent that the Company notifies the Employee Stockholder Entities of its intent to exercise its rights under Section 5), and then in any such case the following terms shall apply: 

(i) any shares of Stock that are to be purchased by the Company pursuant to Section 4 or 5, as applicable, may only
be so purchased if and when such shares have been held by the applicable Employee Stockholder Entities for at least six months; and 
 (ii) with respect to any exercisable Options, upon the occurrence of the applicable event identified in Section 4 giving rise to the Employee Stockholder’s rights thereunder or a Call Event, the
Employee Stockholder Entities may be required by the Company to elect, in accordance with the terms of the relevant Award Agreement, to receive from the Company, on one occasion, in exchange for all of the exercisable Options then held by the
applicable Employee Stockholder Entities, if any, a number of shares of Stock equal to the quotient of (x) the product of (A) the excess, if any, of the Fair Market Value over the Option Exercise Price and (B) the number of shares
then acquirable on exercise, divided by (y) the Fair Market Value, which Options shall be terminated in exchange for such payment of shares of Stock (any such shares of Stock so 

  
 15 

 
acquired, the “Net Settled Stock”). (In the event the foregoing Option Excess Price is zero or a negative number, all outstanding exercisable Options shall be automatically
terminated without any payment in respect thereof.) Upon the occurrence of such net settlement of all exercisable Options, the Put Period or the Call Period, as applicable, shall be deemed to be the period that is thirty (30) days following the
date that is six (6) months after the receipt by the applicable Employee Stockholder Entities of the Net Settled Stock, during which time the Company may, on delivery of Repurchase Notice (or upon delivery of a Redemption Notice), purchase (or
be required to purchase in the case of Section 4) all (in the case of a purchase pursuant to Section 4) or all or any portion (in the case of a purchase pursuant to Section 5) of the Net Settled Stock held by the applicable Employee
Stockholder Entities, at a per share price equal to the applicable Repurchase Price for Option Stock identified in Section 4 or Section 5, as applicable.

not to, among other things, offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Stock as may be reasonably requested by the underwriters in connection with an underwritten offering by
the Company or on behalf of the Sponsors, provided, that such lock-up agreement, will explicitly exempt and exclude any transaction between the Employee Stockholder and the Company pursuant to Section 4 or Section 5 of this
Agreement. In addition to any other remedies available to the Company, upon the failure of the Employee Stockholder to promptly execute and deliver such a lock-up agreement upon request will trigger a 5(b) Call Event with respect to such Stock (but
not the employment of the Employee Stockholder), which such Stock shall be subject to the true-up payment under Section 5(g). 
 9. Additional Rights of Employee Stockholders. Prior to the consummation of the Initial Public Offering, if the Company issues Common Stock in a transaction in which the Investors would be entitled
to preemptive rights and within 90 days following the consummation of such issuance the Employee Stockholders so request, the Board, in its sole discretion, will consider in good faith offering the Employee Stockholders the opportunity to purchase
additional shares of Common Stock. 
 10. Rights to Negotiate Repurchase Price. Nothing in this Agreement shall be deemed
to restrict or prohibit the Company from purchasing, redeeming or otherwise acquiring for value shares of Stock or Options from the Employee Stockholder, at any time, upon such terms and conditions, and for such price, as may be mutually agreed upon
in writing between the 

  
 22 

 
Parties, whether or not at the time of such purchase, redemption or acquisition circumstances exist which specifically grant the Company the right to purchase, or the Employee Stockholder the
right to sell, shares of Stock or any Options under the terms of this Agreement; provided that no such purchase, redemption or acquisition shall be consummated, and no agreement with respect to any such purchase, redemption or acquisition shall be
entered into, without the prior approval of the Board. 
 11. Notice of Change of Beneficiary. Immediately prior to any
transfer of Stock to a Employee Stockholder’s Trust, the Employee Stockholder shall provide the Company with a copy of the instruments creating the Employee Stockholder’s Trust and with the identity of the beneficiaries of the Employee
Stockholder’s Trust. The Employee Stockholder shall notify the Company as soon as practicable prior to any change in the identity of any beneficiary of the Employee Stockholder’s Trust. 

12. Recapitalizations, etc. The provisions of this Agreement shall apply, to the full extent set forth herein with respect to the
Stock or the Options, to any and all shares of capital stock of the Company or any capital stock, partnership units or any other security evidencing ownership interests in any successor or assign of the Company (whether by merger, consolidation,
sale of assets or otherwise) which may be issued in respect of, in exchange for, or substitution of the Stock or the Options by reason of any stock dividend, split, reverse split, combination, recapitalization, liquidation, reclassification, merger,
consolidation or otherwise, and in the event of any of the foregoing occurrences, all references to shares of Common Stock, Option Exercise Prices and any other per share purchase price of Common Stock contained herein shall refer to such shares and
prices as the same may be adjusted in connection with any of the foregoing. 
 13. Employee Stockholder’s Employment by
the Company Group. Nothing contained in this Agreement (a) obligates the Company Group to employ the Employee Stockholder in any capacity whatsoever or (b) prohibits or restricts the Company Group from terminating the employment of the
Employee Stockholder at any time or for any reason whatsoever, with or without Cause, and the Employee Stockholder hereby acknowledges and agrees that neither the Company Group nor any other Person has made any representations or promises whatsoever
to the Employee Stockholder concerning the Employee Stockholder’s employment or continued employment by the Company Group. 

14. Binding Effect. The provisions of this Agreement shall be binding upon and accrue to the benefit of the parties hereto and
their respective heirs, legal representatives, successors and assigns. In the case of a transferee permitted under Section 2(a) or Section 3(a) (other than clauses (iii), (iv) or (vi) thereof) hereof, such transferee shall be
deemed the Employee Stockholder hereunder; provided, however, that no transferee (including without limitation, transferees referred to in Section 2(a) or Section 3(a) hereof) shall derive any rights under this Agreement unless and
until such transferee has delivered to the Company a valid undertaking and becomes bound by the terms of this Agreement. No provision of this Agreement is intended to or shall confer upon any Person other than the Parties any rights or remedies
hereunder or with respect hereto. 

  
 23 

 15. Amendment. This Agreement may be amended by the Company at any time upon notice
to the Employee Stockholder thereof; provided that (i) any amendment that materially disadvantages the Employee Stockholder shall not be effective unless and until the Employee Stockholder has consented thereto in writing and
(ii) any amendment that disadvantages the Employee Stockholder in more than a de minimis way but less than a material way shall require the consent of a majority of the members of Samson’s Executive Team, consisting of the Chief Executive
Officer, the Chief Operating Officer, and the Chief Financial Officer, or, in the absence of any such Officer, the highest ranking Vice President of Samson performing the duties of any such Officer at the time of such amendment. 

16. Closing. Except as otherwise provided herein, the closing of each purchase and sale of shares of Stock pursuant to this
Agreement shall take place at the principal office of the Samson on the tenth business day following delivery of the notice by either Party to the other of its exercise of the right to purchase or sell such Stock hereunder. 

17. Applicable Law; Jurisdiction; Dispute Resolution; Legal Fees. 

(a) The laws of the State of Delaware applicable to contracts executed and to be performed entirely in such state shall govern the
interpretation, validity and performance of the terms of this Agreement. 
 (b) In the event of any controversy among the parties
hereto arising out of, or relating to, this Agreement which cannot be settled amicably by the parties, such controversy shall be treated as if it were a controversy under such Employee Stockholder’s employment agreement, if such Employee
Stockholder’s employment agreement became effective on or before the date hereof, but if such Employee Stockholder is not a party to any such employment agreement at the time of such dispute, such controversy which cannot be settled amicably by
the parties shall be finally, exclusively and conclusively settled by mandatory arbitration conducted expeditiously in accordance with the American Arbitration Association rules, by a single independent arbitrator. Such arbitration process shall
take place in Tulsa, OK. The decision of the arbitrator shall be final and binding upon all parties hereto and shall be rendered pursuant to a written decision, which contains a detailed recital of the arbitrator’s reasoning. Judgment upon the
award rendered may be entered in any court having jurisdiction thereof. Each party shall bear its own legal fees and expenses incurred in connection with such arbitration, unless otherwise determined by the arbitrator. 

(c) Notwithstanding the foregoing, the Employee Stockholder acknowledges and agrees that the Company, the Company Group, the Investors,
the Sponsors and any of their respective Affiliates shall be entitled to injunctive or other relief in order to enforce the covenant not to solicit and/or confidentiality covenants as set forth in Section 22(a) of this Agreement. 

(d) In the event of any arbitration or other disputes with regard to this Agreement or any other document or agreement referred to herein,
each Party shall pay its own legal fees and expenses, unless otherwise determined by the arbitrator. 
 18. Assignability by
the Company. The Company shall have the right to assign (i) any or all of its rights or obligations to purchase shares of Stock pursuant to Sections 4 and 5 hereof and (ii) any or all of its other rights or obligations hereunder to any
part of the Company Group; provided, however, that no such assignment shall relieve the Company from its obligations thereunder. 

  
 24 

 19. Miscellaneous. 

(a) In this Agreement all references to “dollars” or “$” are to United States dollars and the masculine pronoun shall
include the feminine and neuter, and the singular the plural, where the context so indicates. 
 (b) If any provision of this
Agreement shall be declared illegal, void or unenforceable by any court of competent jurisdiction, the other provisions shall not be affected, but shall remain in full force and effect. 

(c) This Agreement is being executed in addition to the outstanding change of control agreement between the Employee Stockholder and
Samson (the “Change of Control Agreement”) and this Agreement does not replace, amend, supersede or override the Change of Control Agreement in any respect. The parties to this agreement acknowledge that this Agreement is intended
only to govern the Stock and Options of the Employee Stockholder. In the event of any conflict between this Agreement and the Change of Control Agreement, the Change of Control Agreement shall control. 

(d) Nothing in this Agreement shall be read to require any change to the Option Plan that would affect the Company’s ability to rely
on the exemption from registration under the Exchange Act available under Rule 12h-1(f) or Rule 12h-1(g), as amended. In any conflict between the provisions of this Agreement and the Option Plan that would affect the Company’s ability to rely
on the exemption from registration under the Exchange Act available under Rule 12h-1(f) or Rule 12h-1(g), as amended, the provisions that comply with Rule 12h-1(f) or Rule 12h-1(g) (as applicable) will control. Notwithstanding the foregoing, the
transfer restrictions on the Stock and Options set forth in this Agreement shall not be reduced, eliminated or otherwise altered except in accordance with the terms of this Agreement. 

20. Withholding. The Company Group shall have the right to deduct from any cash payment made under this Agreement to the applicable
Employee Stockholder Entities any federal, state or local income or other taxes required by law to be withheld with respect to such payment, if applicable. 
 21. Notices. All notices and other communications provided for herein shall be in writing. Any notice or other communication hereunder shall be deemed duly given (i) upon electronic

 22. Confidential Information; Covenant Not to Solicit. 

(a) In consideration of the Company entering into this Agreement with the Employee Stockholder, the Employee Stockholder hereby covenants
and agrees he or she shall not: 
 (i) at any time during or after the Employee Stockholder’s employment
with the Company or its subsidiaries, disclose any Confidential Information or proprietary information pertaining to the business of the Company or the Company Group or the Investors or the Sponsors or any of their respective Affiliates, except when
required by law or while employed by the Company Group for the benefit of the Company Group; and 
 (ii) at any
time during the Employee Stockholder’s employment with the Company Group and for the eighteen (18) month period thereafter, solicit or hire any Person who is, or was during the eighteen (18) months preceding the time of the
solicitation or hiring, employed by the Company Group other than for the benefit of (i) the Company Group, (ii) the Investors, (iii) the Sponsors and (iv) each of their respective Affiliates. 

  
 26 

 (b) Notwithstanding clause (a) above, if at any time a court holds that the
restrictions stated in such clause (a) are unreasonable or otherwise unenforceable under circumstances then existing, the parties hereto agree that the maximum period, scope or geographic area determined to be reasonable under such
circumstances by such court will be substituted for the stated period, scope or area. Because the Employee Stockholder’s services are unique and because the Employee Stockholder has had access to Confidential Information, the parties hereto
agree that money damages will be an inadequate remedy for any breach of this Agreement. In the event of a breach or threatened breach of this Agreement, the Company or its successors or assigns may, in addition to other rights and remedies existing
in their favor, apply to any court of competent jurisdiction for specific performance and/or injunctive relief in order to enforce, or prevent any violations of, the provisions hereof (without the posting of a bond or other security). 

(c) In the event that the Employee Stockholder breaches any of the provisions of Section 22(a), in addition to all other remedies
that may be available to the Company, the Employee Stockholder’s equity shall be treated in the same manner as if the Employee Stockholder’s employment had been terminated for Cause by the Company Group. 

(d) Each of the Investors and the Sponsors shall be direct third party beneficiaries with respect to the provisions this Section 22.

 23. Effectiveness. Upon execution and delivery of this Agreement by the parties hereto, this Agreement shall become
effective as of the date hereof.

 SAMSON RESOURCES CORPORATION 
 OPTION AWARD AGREEMENT

 (STANDARD FORM) 
 THIS OPTION AWARD AGREEMENT (this “Agreement”), dated as of April 16, 2012 (the “Grant Date”) is made by and between Samson Resources Corporation, a Delaware
corporation (hereinafter referred to as the “Company”), and the individual (the “Optionee”) whose name is set forth on the signature page hereof, who is a Participant. Any capitalized terms used but not otherwise
defined herein shall have the meaning set forth in the Samson Resources Corporation 2011 Stock Incentive Plan, as amended, modified or supplemented from time to time (the “Plan”). 

WHEREAS, as an incentive for the Optionee’s efforts in connection with his or her Employment by, or performance of other services
for, the Company, Samson Investment Company, a Nevada corporation and a wholly owned subsidiary of the Company (“Samson” and together with the Company and their direct and indirect subsidiaries, the “Company
Group”), the Company wishes to afford the Optionee the opportunity to purchase a number of Shares (which Shares shall entitle the Optionee to any and all rights and benefits to which the holder of such Shares may be provided), subject to
the terms and conditions set forth herein and in the Plan; and 
 WHEREAS, the Company wishes to carry out the Plan, the terms
of which are hereby incorporated by reference and made a part of this Agreement, pursuant to which the Committee, appointed to administer the Plan, has instructed the undersigned officers to issue this Option. 

NOW, THEREFORE, in consideration of the mutual covenants herein contained and other good and valuable consideration, receipt of which is
hereby acknowledged, the parties hereto do hereby agree as follows: 
 ARTICLE I 

DEFINITIONS 
 Whenever the following terms are used in this Agreement, they shall have the meaning specified below unless the context clearly indicates to the contrary. 

Section 1.1. Cause 

“Cause” means the occurrence of any of the following events: (a) Optionee’s commission of any serious crime
involving fraud, dishonesty or a breach of trust as to the Company Group (including but not limited to, misrepresentation, embezzlement, or misappropriation); (b) Optionee’s material violation of either (i) any applicable confidential
and proprietary information policy of the Company Group or (ii) any applicable code of conduct policy of the Company Group, as then in effect; (c) Optionee’s conviction, guilty plea, no contest plea, deferred adjudication or other
trial diversion regarding any felony or any crime involving moral turpitude; or (d) Optionee’s failure to perform his or her duties in any material respect (other than any failure resulting from Optionee’s incapacity due to physical
or mental illness or disability) or Optionee’s gross negligence or intentional misconduct in the performance of his or her duties, including any act or acts which affect the image or reputation of the Company or any part of the Company Group or
which result in material financial loss to any part of the Company Group. Notwithstanding the immediately preceding item (d), any of the circumstances described in said item (d) may not serve as the basis for Cause unless (x) the
Company provides written notice to Optionee within thirty (30) days following the Company’s initial knowledge of the existence and effect of the event(s) constituting Cause and (y) Optionee fails to cure such event(s) within
thirty (30) days after receipt of such notice. Furthermore, no act or failure to act by Optionee shall be considered “intentional” unless done or omitted to be done by Optionee in bad faith and without reasonable belief that his or
her action or omission was in the best interests of the Company Group. 

 Section 1.2. Closing Date 

“Closing Date” means December 21, 2011. 
 Section 1.3. Employed or Employment 
 “Employed” or
“Employment” means employment by the Company Group as an employee or the performance of services (whether as employee, consultant, director or other service provider) to the Company Group. 

Section 1.4. Fiscal Year  
 “Fiscal Year” means each fiscal year of the Company. 
 Section 1.5. Good
Reason 
 “Good Reason” means the occurrence of any of the following events without Optionee’s prior
agreement and written consent: (a) a diminution in Optionee’s annual base salary or annual bonus (except as such annual bonus may be affected by the performance of any of the Company Group, the Company Group business unit in which Optionee
works, or the Optionee); (b) relocation of Optionee’s primary place of employment to a location more than 50 miles from his or her primary place of employment; (c) a material breach by any part of the Company Group of any of its
obligations to Optionee under this Agreement or any employment agreement between Optionee and any part of the Company Group; or (d) the assignment of duties and responsibilities on a continuing basis to Optionee that are materially inconsistent
with Optionee’s title or position at the applicable part of the Company Group prior to such assignment. Notwithstanding the foregoing, any of the circumstances described in the items immediately above may not serve as the basis for Good Reason
unless (i) Optionee provides written notice to the Company within thirty (30) days of Optionee’s initial knowledge of the existence and effect of the event(s) constituting Good Reason and (ii) the Company Group fails to cure (to
the extent curable) such events(s) within thirty (30) days after receipt from Optionee of such notice; provided that Good Reason will cease to exist with respect to an event thirty-one (31) days following Optionee’s initial
knowledge of the existence and effect of such event, and Optionee will be deemed to have waived the right to claim Good Reason with respect to that event, provided further that the separate occurrence of an event similar to a waived event but
arising out of new facts or circumstances will also constitute Good Reason and will be subject to a separate written notice and waiver procedure. 
 Section 1.6. Option

purchase Shares of the Company granted to the Optionee under Section 2.1 of this Agreement.

Company grants to the Optionee an option to purchase any part or all of an aggregate of the number of Shares set forth on the signature page hereof, at the exercise price set forth on the signature page hereof (which is the Fair Market Value per
Share on the Grant Date), without commission or other charge. 
 ARTICLE III 

PERIOD OF EXERCISABILITY 

Section 3.1. Vesting and Commencement of Exercisability 
 (a) Vesting. So long as the Optionee continues to be Employed through each relevant vesting date, the Shares subject to the Option shall vest based on elapsed time, such that the Option shall
become vested and exercisable with respect to 25% of the Shares subject to such Option on each of the first four anniversaries of the Closing Date. 
 (b) Death, Disability, Good Reason, other than Cause. Notwithstanding any of the foregoing, upon a termination of the Optionee’s Employment at any time by reason of death, Disability or Good
Reason, or upon the Company Group’s termination of Optionee’s employment for other than Cause, that 25% portion of the Option that would have become exercisable on the next Closing Date anniversary if the Optionee had remained Employed
with the Company Group through such date will become vested and exercisable as of such termination. 
 (c) Change of
Control. Notwithstanding any of Section 3.1(a) or (b) above, upon a Change of Control, any then-outstanding and unvested Option shall become immediately exercisable as to 100% of the Shares subject to such Option immediately prior to a
Change of Control (but only to the extent such Option has not otherwise terminated or become exercisable). 
 Section 3.2. Expiration of
Option 
 The exercisable portion of any Option (including any portion that becomes exercisable pursuant to
Section 3.1(b) or Section 3.1(c) above prior to any termination of employment) shall lapse if not timely exercised pursuant to this Section 3.2. The Optionee must exercise the exercisable portion of the Option to any extent on or
prior to the first to occur of the following events: 
 (a) the tenth anniversary of the Grant Date; 

(b) the first anniversary of the date of the Optionee’s termination of Employment, if the Optionee’s Employment is terminated by
reason of death or Disability; 
 (c) one hundred eighty (180) days after the date of an Optionee’s termination of
Employment by the Company Group without Cause (for any reason other than as set forth in Section 3.2(b)) or by the Optionee for Good Reason; 

  
 3 

 (d) immediately upon the date of the Optionee’s termination of Employment by the
Company Group for Cause; 
 (e) thirty (30) days after the date of the Optionee’s voluntary termination of Employment
without Good Reason; 
 (f) the date the Option is terminated pursuant to Section 4 or 5 of the Stockholder’s
Agreement; or 
 (g) if the Committee so determines pursuant to Section 7 or 8 of the Plan. 

The portion of any Option that is not exercisable at the time of an Optionee’s termination of employment for any reason (and that
does not become exercisable pursuant to Section 3.1(b) or (c) above prior to such termination) shall lapse and be of no further effect upon such termination of employment. 

ARTICLE IV 

EXERCISE OF OPTION 

Section 4.1. Person Eligible to Exercise 
 Except as expressly provided for herein, in the Plan or in the Stockholder’s Agreement, during the lifetime of the Optionee, only the Optionee may exercise the Option or any portion thereof. After
the Disability or death of the Optionee, any exercisable portion of the Option may, prior to the time when the Option becomes unexercisable under Section 3.2, be exercised by the Optionee’s legatees, personal representatives, or
distributees. 
 Section 4.2. Partial Exercise 
 Any exercisable portion of the Option or the entire Option, if then wholly exercisable, may be exercised in whole or in part at any time prior to the time when the Option or portion thereof becomes
unexercisable under Section 3.2; provided however, that any partial exercise shall be for whole Shares only. 
 Section 4.3. Manner
of Exercise 
 The Option, or any exercisable portion thereof, may be exercised solely by delivering to the Secretary of the
Company all of the following on or prior to the time when the Option or such portion becomes unexercisable under Section 3.2, and the satisfaction of all of the foregoing shall be determined in the discretion of the Company: 

(a) notice in writing signed by the Optionee or any other person then entitled to exercise the Option or portion thereof, stating that the
Option or portion thereof is thereby exercised, such notice complying with all applicable rules established by the Committee; 

(b) full payment of the exercise price applicable to any Option in cash, by check, in Shares (any such Shares valued at Fair Market Value
on the date of exercise) that the Optionee has held for at least six months (or such lesser period of time as may be required by the Company’s accountants), through the withholding of Shares (any such Shares valued at Fair Market Value on the
date of exercise) otherwise issuable upon the exercise of the Option in a manner that is compliant with applicable law, or a combination of the foregoing methods; 

  
 4 

 (c) execution, to the extent not previously executed, of the Stockholder’s Agreement
and such other documents and instruments as may be reasonably required by the Committee under the Plan; 
 (d) full payment to
the Company of all amounts which, under federal, state or local law, it (or an Affiliate) is required to withhold upon exercise of the Option, except as otherwise agreed to by the Company under the Plan; 

(e) in the event the Option or portion thereof shall be exercised pursuant to Section 4.1 by any person or persons other than the
Optionee, appropriate proof of the right of such person or persons to exercise the option; and 
 (f) if so requested by the
Committee, an irrevocable voting proxy and power of attorney in favor of a designated member of the Board. 
 In addition, following an Initial
Public Offering by the Company, the Optionee may satisfy his or her obligations under Section 4.3(b) and/or (c) through the sale of Shares (or equity securities into which Shares are convertible) into the public market pursuant to a
cashless exercise program that is compliant with applicable law, to the extent the sale of such Shares (or equity securities, as applicable) is permitted under the Stockholder’s Agreement. 

Without limiting the generality of the foregoing, the Committee may require an opinion of counsel acceptable to it to the effect that any subsequent
transfer of Shares acquired on exercise of the Option does not violate the Securities Act of 1933, as amended, and may issue stop-transfer orders covering such Shares. 
 Section 4.4. Conditions to Issuance of Shares 
 The Company shall not
be required to record the ownership by the Optionee of Shares purchased upon the exercise of the Option or portion thereof prior to fulfillment of all of the following conditions: 

(a) the obtaining of approval or other clearance from any federal, state, local or non-U.S. governmental agency which the Committee shall,
in its reasonable and good faith discretion, determine to be necessary; 
 (b) the lapse of such reasonable period of time
following the exercise of the Option as may otherwise be required by applicable law; and 
 (c) the execution and delivery of the
Stockholder’s Agreement. 
 Section 4.5. Rights as Shareholder 

The Optionee shall not be, and shall not have any of the rights or privileges of, shareholders of the Company in respect of any Shares
purchasable upon exercise of the Option or any portion thereof unless and until a book entry representing such Shares has been made on the books and records of the Company; provided, however, that the Optionee shall be deemed to be admitted as a
shareholder, retroactive to the date of exercise, once the criteria contained in Sections 4.3 and 4.4 hereof have been satisfied. 

  
 5 

 ARTICLE V 
 MISCELLANEOUS 
 Section 5.1. Administration 

The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation
and application of the Plan as are consistent therewith and to interpret or revoke any such rules and all actions taken and all interpretations and determinations made by the Committee in good faith shall be final and binding upon the Optionee, the
Company and all other interested persons. In its absolute discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Committee under the Plan and this Agreement. 

Section 5.2. Notices 

Any notice to be given under the terms of this Agreement to the Company shall be addressed to the Company in care of the Secretary, and
any notice to be given to the Optionee shall be addressed to the Optionee at the address set forth in the Company’s books and records. By a notice given pursuant to this Section 5.2, either party may hereafter designate a different address
for notices to be given to that party. Any notice which is required to be given to the Optionee, shall, if the Optionee is then deceased, be given to the Optionee’s personal representative if such representative has previously informed the
Company of the representative’s status and address by written notice under this Section 5.2. 
 Section 5.3. Survival of
Terms; Conflicts  
 The Option and the Shares issued to the Optionee upon exercise of the Option shall be subject to all of
the terms and provisions of the Plan and the Stockholder’s Agreement, to the extent applicable to the Option and such Shares. The Agreement remains subject to the terms of the Plan, and, in the event of any conflict between specific provisions
of the Plan and the Agreement, the Agreement shall control. The provisions of the Agreement shall survive the termination of the Agreement to the extent consistent with, or necessary to carry out, the purposes thereof. In the event of any conflict
between this Agreement and the Stockholder’s Agreement, the Stockholder’s Agreement shall control. 
 Notwithstanding
anything in the paragraph above, nothing in this Agreement shall be read to require any change to the Plan that would affect the Company’s ability to rely on the exemption from registration under the Exchange Act available under Rule 12h-1(f)
or Rule 12h-1(g), as amended. In any conflict between the provisions of this Agreement and the Plan that would affect the Company’s ability to rely on the exemption from registration under the Exchange Act available under Rule 12h-1(f) or Rule
12h-1(g), as amended, the provisions that comply with Rule 12h-1(f) or Rule 12h-1(g) (as applicable) will control. Notwithstanding the foregoing, the transfer restrictions on the Option and Shares set forth in this Agreement shall not be reduced,
eliminated or otherwise altered except in accordance with the terms of this Agreement. 
 Section 5.4. Amendment 

Subject to Section 9 of the Plan, this Agreement may be amended only by a writing executed by the parties hereto, which specifically
states that it is amending this Agreement. 

  
 6 

 Section 5.5. Governing Law 

This Agreement shall be governed in all respects by the laws of the State of Delaware, without giving effect to the principal of conflict
of laws. 
 Section 5.6. Disputes 
 Notwithstanding anything in Section 14(h) of the Plan to the contrary, in the event of any controversy among the parties hereto arising out of, or relating to, this Agreement which cannot be settled
amicably by the parties, such controversy shall be treated as if it were a controversy under such Optionee’s employment agreement, but if such Optionee is not a party to any such employment agreement at the time of such dispute, such
controversy shall be finally, exclusively and conclusively settled by mandatory arbitration conducted expeditiously in accordance with the American Arbitration Association rules, by a single independent arbitrator. Such arbitration process shall
take place in Tulsa, OK. The decision of the arbitrator shall be final and binding upon all parties hereto and shall be rendered pursuant to a written decision, which contains a detailed recital of the arbitrator’s reasoning. Judgment upon the
award rendered may be entered in any court having jurisdiction thereof. Each party shall bear its own legal fees and expenses, unless otherwise determined by the arbitrator. Each party hereto hereby irrevocably waives any right that it may have had
to bring an action in any court, domestic or foreign, or before any similar domestic or foreign authority with respect to this Agreement. 

Section 5.7. Conformity to Section 409A  
 It is intended that the Option either be exempt from or comply with Section 409A, and this Agreement shall be interpreted accordingly. The Committee shall use commercially reasonable efforts to
