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.

4. The Employee Stockholder’s Right to Resell Stock and Options 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

vested Options then held by the applicable Employee Stockholder Entities for an amount equal to the sum of the excess, if any, of the Section 4 Repurchase Price over the Option Exercise 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”) 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 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

(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”).

(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.

(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.

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.

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:

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

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.

(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.

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

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.

(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

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.

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

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.

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.

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.

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.

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.

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.

(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.
