valuation method shall be in accordance with Section 409A, to the extent applicable. The Committee may adopt a different methodology for determining Fair Market Value if necessary or advisable to secure any intended favorable tax, legal or

	4.	Awards 

 (a) From time to time, the Committee will determine the form, amounts, terms,
conditions and limitations of Awards, consistent with the terms of this Plan. The form, amount, terms, conditions and limitations of each Award under the Plan shall be set forth in an Award Agreement, in a form approved by the Committee, consistent,
however, with the terms of the Plan; provided, however, that such Award Agreement shall contain provisions dealing with the treatment of Awards in the event of the termination of employment or service (as applicable), Disability or death of a
Participant. Such Awards may take the following forms described in Section 4(b) and 4(c) hereunder, in the Committee’s sole discretion.

Agreement or as the Committee may determine, the purchase price for the Units as to which a Unit Option is exercised shall be paid in full at the time of exercise at the election of the
Participant (i) in cash, (ii) with the consent of the Committee, in Units (any such Units valued at Fair Market Value on the date of exercise), provided that accepting such Units shall not result in adverse accounting consequences to the
Company, (iii) with the consent of the Committee, through the withholding of Units (any such Units valued at Fair Market Value on the date of exercise) otherwise issuable upon the exercise of the Unit Option in a manner that is compliant with
applicable law, or (iv) a combination of the foregoing methods, in each such case in accordance with the terms of the Plan and the Award Agreement; provided, that the Participant will pay any taxes due in respect of such exercise in cash. No
Participant shall have any rights to distributions or other rights of a Unit holder with respect to Units subject to a Unit Option until the Participant has given written notice of exercise of the Unit Option, the Participant has paid in full for
such Units, the Units in question have been recorded on the Company’s register of interest holders, and if applicable, the Participant has satisfied any other conditions imposed by the Company pursuant to the Plan. 

(c) An Award may be made by the Committee in the form of restricted Units, phantom Units, warrants or other securities that are convertible,
exercisable or exchangeable for or into Units, or based on the Fair Market Value of Units in which case the Award Agreement evidencing such Award shall include, inter alia, such terms, conditions or restrictions, as the Committee determines
appropriate. Unless otherwise agreed by the Committee or provided in any Award Agreement, the Participant will pay any taxes due in respect or any Award in cash.

restricted Units), the Participant will be required to become a party to the LLC Agreement, execute such other documents and instruments as are reasonably and customarily required by the Company to evidence compliance with applicable federal and
state securities and “blue sky” laws, and the Units acquired will be held subject to, and in compliance with, the terms and conditions of the LLC Agreement. 

(e) Subject to Section 2.9(c) of the LLC Agreement, in connection with an IPO Reorganization, each Participant shall be required to take
such actions as may be reasonably required by the Executive Committee and otherwise cooperate in good faith with the Executive Committee, including, but not limited to, executing and delivering all agreements, instruments and documents as may be
reasonably required in order to consummate an IPO Reorganization. 
  

	5.	Units Subject to the Plan; Limitations and Conditions 

 (a) Subject to Section 8,
the number of Units available for Awards under this Plan shall be equal to [            ] Units. Unless restricted by applicable law, Units related to Awards that are forfeited, terminated,
canceled or expire unexercised shall immediately become available for new Awards. 
 (b) No Awards shall be granted under the Plan beyond
ten years after the Effective Date, but the terms of Awards made on or before the expiration of the Plan may extend beyond such expiration date. At the time an Award is made or amended or the terms or conditions of an Award are changed in accordance
with the terms of the Plan or the Award Agreement, the Committee may provide for limitations or conditions on such Award. 

  
 -5- 








 (c) No such Awards shall, prior to vesting and delivery thereof to the Participant, be in any
manner liable for or subject to the debts, contracts, liabilities, engagements, or torts of the Participant. 
 (d) Unless otherwise
determined by the Committee, an Award shall not be transferable or assignable by the Participant other than by will or by the laws of descent and distribution. An Award exercisable after the death of a Participant may be exercised by his legatees,
personal representative, or distributees. 
 (e) Participants shall not be, and shall not have any of the rights or privileges of, Members
of the Company in respect of any Awards exercisable, settled, convertible or exchangeable into Units, unless and until book entry representing such Units has been made and admission of the Participant as a Member pursuant to the LLC Agreement has
occurred. 
 (f) Except as otherwise determined by the Committee, no exercise of any Award may be made during a Participant’s lifetime
by anyone other than the Participant, except by a legal representative appointed for or by the Participant in accordance with the requirements set forth by the Company. 

(g) Absent express provisions to the contrary, any Award under this Plan shall not be deemed compensation for purposes of computing benefits
or contributions under any retirement or severance plan of the Company or its Affiliates and shall not affect any benefits under any other benefit plan of any kind now or subsequently in effect under which the availability or amount of benefits is
related to level of compensation. 
 (h) The Unit Option Price per Unit shall be determined by the Committee, but shall not be less than
100% of the Fair Market Value of a Unit on the date a Unit Option is granted (other than in the case of Unit Options granted in substitution of previously granted awards). 
  

	6.	Other Unit-Based Awards 

 The Committee, in its sole discretion, may grant or sell Awards
of Units, Awards of restricted Units and Awards that are valued in whole or in part by reference to, or are otherwise based on the Fair Market Value of, Units (such Awards, “Other Unit-Based Awards”). Such Other Unit-Based Awards
shall be in such form, and dependent on such conditions, as the Committee shall determine, including, without limitation, the right to receive, or vest with respect to, one or more Units (or the equivalent cash value of such Units) upon the
completion of a specified period of service, the occurrence of an event and/or the attainment of performance objectives. Other Unit-Based Awards may be granted alone or in addition to any other Awards granted under the Plan. Subject to the
provisions of the Plan, the Committee shall determine to whom and when Other Unit-Based Awards will be made, the number of Units to be awarded under (or otherwise related to) such Other Unit-Based Awards, whether such Other Unit-Based Awards shall
be settled in cash, Units or a combination of cash and Units, and all other terms and conditions of such Awards (including, without limitation, the vesting provisions thereof and provisions ensuring that all Units so awarded and issued shall be
fully paid and non-assessable). 

  
 -6- 









	7.	Transfers and Leaves of Absence 

 For purposes of the Plan, unless the Committee
determines otherwise: (a) a transfer of a Participant’s employment without an intervening period of separation among the Company and any of its Affiliates shall not be deemed a termination of employment, and (b) a Participant who is
awarded in writing a leave of absence or who is entitled to a statutory leave of absence shall be deemed to have remained in the employ of the Company (and any of its Affiliates) during such leave of absence. In the case of an Award subject to
Section 409A, no termination shall be deemed a termination from employment unless it is a “separation from service” under Section 409A. 
  

	8.	Adjustments Upon Certain Events 

 Notwithstanding any other provisions in the Plan to the
contrary, the following provisions shall apply to all Awards granted under the Plan: 
 (a) Generally. In the event of any change in
the outstanding Units after the Effective Date by reason of any Unit split, reorganization, recapitalization, merger, consolidation, spin-off, combination, combination or transaction or exchange of Units or other corporate exchange, or any
extraordinary distribution to members of the Company (which shall not, for the avoidance of doubt, include any tax distributions) or any transaction similar to the foregoing, the Committee, without liability to any Person, shall make such
substitution or adjustment, if any, in the manner it deems to be equitable (subject to Section 12), as to (i) the number or kind of Units or other securities issued or reserved for issuance pursuant to the Plan or pursuant to outstanding
Awards, (ii) the maximum number of Units for which Unit Options may be granted during a fiscal year to any Participant, (iii) the exercise price of any Award and/or (iv) any other affected terms of such Awards. 

(b) Change in Control. In the event of a Change in Control after the Effective Date, (i if determined by the Committee in the
applicable Award Agreement or otherwise, any outstanding Awards then held by Participants which are unexercisable or otherwise unvested or subject to lapse restrictions shall automatically be deemed exercisable or otherwise vested or no longer
subject to lapse restrictions, as the case may be, as of immediately prior to such Change in Control and (ii) the Committee may (subject to Section 12), but shall not be obligated to, (A) accelerate, vest or cause the restrictions to
lapse with respect to all or any portion of an Award, (B) cancel such Awards for fair value (as determined in the sole discretion of the Committee) which, in the case of Unit Options, may equal the excess, if any, of value of the consideration
to be paid in the Change in Control transaction to holders of the same number of Units subject to such Unit Options (or, if no consideration is paid in any such transaction, the Fair Market Value of the Units subject to such Unit Options) over the
aggregate exercise price of such Unit Options, (C) provide for the issuance of substitute Awards that will substantially preserve the otherwise applicable terms of any affected Awards previously granted hereunder as determined by the Committee
in its sole discretion or (D) provide that for a period of at least 15 days prior to the Change in Control, such Unit Options shall be exercisable as to all Units subject thereto and that upon the occurrence of the Change in Control, such Unit
Options shall terminate and be of no further force and effect. For the avoidance of 

  
 -7- 








 
doubt, pursuant to (B) above, the Committee may cancel and pay no consideration for all, or any portion of, Unit Options if the Fair Market Value of any Unit subject to such Unit Options is
less than or equal to the Unit Option Price of such Unit Options, but only with respect to those Units where such deficit exists. 
  

	9.	Forfeiture/Clawback 

 The Committee may, in its sole discretion, specify in an Award that
the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or
performance conditions of an Award. Such events may include, but shall not be limited to, termination of employment for cause, termination of the Participant’s provision of services to the Company or any of its subsidiaries, breach of
noncompetition, confidentiality, or other restrictive covenants that may apply to the Participant, or restatement of the Company’s financial statements to reflect adverse results from those previously released financial statements, as a
consequence of errors, omissions, fraud, or misconduct. 
  

	10.	Amendment and Termination 

 (a) The Committee shall have the authority to make such
amendments to any outstanding Awards as are consistent with this Plan, provided that no such action shall modify any Award in a manner adverse in any material respect to the Participant without the Participant’s consent except as such
modification is provided for or contemplated in the terms of the Award or this Plan (including, for the avoidance of doubt, pursuant to Sections 8 or 9 hereof). Without limiting the generality of the foregoing, to the extent applicable,
notwithstanding anything herein to the contrary, this Plan and Awards issued hereunder shall be interpreted in accordance with Section 409A and Department of Treasury regulations and other interpretative guidance issued thereunder, including
without limitation any such regulations or other guidance that may be issued after the Effective Date. Notwithstanding any provision of the Plan to the contrary, in the event that the Committee determines that any amounts payable hereunder will be
taxable to a Participant under Section 409A and related Department of Treasury guidance prior to payment to such Participant of such amount, the Company may (a) adopt such amendments to the Plan and Awards and appropriate policies and
procedures, including amendments and policies with retroactive effect, that the Committee determines necessary or appropriate to preserve the intended tax treatment of the benefits provided by the Plan and Awards hereunder and/or (b) take such
other actions as the Committee determines necessary or appropriate to avoid the imposition of an additional tax under Section 409A. 

(b) The Board may amend, suspend or terminate the Plan except that no such action, other than an action under Sections 8 or 9 hereof, may
be taken which would, without Member approval, increase the aggregate number of Units available for Awards under the Plan, decrease the price of outstanding Awards, change the requirements relating to the Committee as set forth in Section 3
hereof, or extend the term of the Plan. 

  
 -8- 









	11.	Governing Law 

 (a) This Plan shall be governed in all respects by the laws of the State
of Delaware without giving effect to the principle of conflict of laws. 
 (b) The Committee may make Awards to employees, non-employee
members of the Board, consultants, or other persons having a relationship with the Company or any of its Affiliates who are subject to the laws of jurisdictions other than those of the United States, which Awards may have terms and conditions that
differ from the terms thereof as provided elsewhere in the Plan for the purpose of complying with non-US, laws or otherwise as deemed to be necessary or desirable by the Committee. 

 

	12.	Conformity to Section 409A 

 It is intended that all Awards under this Plan and any
Award Agreement, either be exempt from or avoid taxation under Section 409A. All Unit Options or other similar Awards that are granted with an exercise price shall be granted with an exercise price such that the Award would not constitute
deferred compensation under Section 409A or shall otherwise be structured to avoid taxation under Section 409A. Any ambiguity in this Plan and any Award Agreement shall be interpreted to comply with Section 409A. To the extent
applicable, as determined in the sole discretion of the Committee with and upon advice of counsel, (a) each amount or benefit payable pursuant to this Plan and any Award Agreement shall be deemed a separate payment for purposes of
Section 409A and (b) in the event the equity interests of the Company are publicly traded on an established securities market or otherwise and the Participant is a “specified employee” (as determined under the Company’s
administrative procedure for such determinations, in accordance with Section 409A) at the time of the Participant’s termination of employment, any payments under this Plan or any Award Agreement that are deemed to be deferred compensation
subject to Section 409A shall not be paid or begin payment until the earlier of the Participant’s death and the first day following the six (6) month anniversary of the Participant’s date of termination of employment. The
Committee shall use commercially reasonable efforts to implement the provisions of this Section 12 in good faith; provided that neither the Company, the Board, the Committee nor any of the Company’s employees, directors or representatives
shall have any liability to Participants with respect to this Section 12. 
  

	13.	Withholding Taxes 

 If the Company and/or any Affiliate shall be required to withhold any
amounts by reason of any Federal, State, local or foreign tax rules or regulations in respect of any Award, the Company and/or any Affiliate shall be entitled to take such action as it deems appropriate in order to ensure compliance with such
withholding requirements. The Company or any of its Affiliates shall have the right, at its option, to (a) require the Participant to pay or provide for payment of the amount of any taxes which the Company or any of its Affiliates may be
required to withhold with respect to such Award, (b) deduct from any amount otherwise payable in cash (whether related to the Award or otherwise) to the Participant the amount of any taxes which the Company or any of its Affiliates may be
required to withhold with respect to such Award, or (c) if the Committee determines, to withhold Units with a Fair Market Value of the minimum amount of any taxes which the Company or any of its Affiliates may be required to withhold with
respect to such Award. 

  
 -9- 









	14.	Effective Date and Termination Dates 

 The Plan shall be effective as of
December 16, 2011 (the “Effective Date”) and shall terminate ten years later, subject to earlier termination by the Board pursuant to Section 10. 
  

	15.	Miscellaneous 

 (a) ERISA. This Plan is not subject to the Employee Retirement
Income Security Act of 1974, as amended. 
 (b) No Right of Employment or Service. Nothing contained herein, in an Award Agreement or
in an Award shall confer on any employee, director or consultant any right to be continued in the employ or service of the Company and/or any Affiliates, constitute any contract or agreement of employment or other service or affect an
employee’s status as an at-will employee, nor shall anything contained herein, in any Award Agreement or an Award affect any rights which the Company and/or its Affiliates may have to change a person’s compensation or other benefits or
terminate such person’s employment or association with the Company and/or its Affiliates for any reason (with or without cause, with or without compensation) at any time. 

(c) Funding. Unless the Committee determines otherwise, no benefit or promise under the Plan shall be secured by any specific assets of
the Company or any of its Affiliates, nor shall any assets of the Company or any of its Affiliates be designated as attributable or allocated to the satisfaction of the Company’s obligations under the Plan. 

(d) Non-Uniform Determinations. The Committee’s determinations under the Plan need not be uniform and may be made by it
selectively among persons who receive or are eligible to receive Awards (whether or not such persons are similarly situated). Without limiting the generality of the foregoing, the Committee shall be entitled, among other things, to make non-uniform
and selective determinations, and to enter into non-uniform and selective Award Agreements, as to the persons to receive Awards under the Plan and the terms and provisions of Awards under the Plan. 

(e) Section Headings; Construction. The section headings contained herein are for the purpose of convenience only and are not
intended to define or limit the contents of the sections. All words used in this Plan shall be construed to be of such gender or number, as the circumstances require. Unless otherwise expressly provided, the word “including” does not limit
the preceding words or terms. 
 (f) Severability; Entire Agreement. In the event any provision of the Plan or any Award Agreement
shall be held by a court of competent jurisdiction to be illegal, invalid or unenforceable for any reason, the illegality, invalidity or unenforceability shall not affect the remaining provisions of the Plan and such Award Agreement and such
illegal, invalid or unenforceable provision shall be deemed modified as it such provision had not been included. 
 (g) Survival of
Terms; Conflicts. The provisions of the Plan shall survive the termination of the Plan to the extent consistent with, or necessary to carry out, the purposes thereof. Each Award Agreement remains subject to the terms of the Plan, however, in the
event of any conflict between specific provisions of the Plan and an Award Agreement, the Award Agreement shall control. 

  
 -10- 








 (h) Arbitration. Any dispute with regard to the enforcement of this Plan and any Award
Agreement hereunder shall be exclusively resolved by a single experienced arbitrator licensed to practice law in the State of Arizona, selected in accordance with the American Arbitration Association (“AAA”) rules and procedures, at
an arbitration to be conducted in the State of Arizona pursuant to the National Rules for the Resolution of Employment Disputes rules of AAA with the arbitrator applying the substantive law of the State of Delaware as provided for under
Section 11(a) hereof. The AAA shall provide the parties hereto with lists for the selection of arbitrators composed entirely of arbitrators who are members of the National Academy of Arbitrators and who have prior experience in the arbitration
of disputes between employers and senior executives. The determination of the arbitrator shall be final and binding on the parties hereto and judgment therein may be entered in any court of competent jurisdiction. Each party shall pay its own
attorneys fees and disbursements and other costs of the arbitration.

 IN WITNESS WHEREOF, the undersigned officer of the Company hereby certifies that the Plan was adopted by the
Board at a meeting duly held on December 16, 2011.

Performance Target in the Missed Year. If, after giving effect to the addition(s) contemplated by the immediately preceding sentence, both components of the Annual Performance Target are satisfied for the Missed Year, the Performance Options
eligible to have vested and become exercisable in the Missed Year shall vest and become exercisable as of the end of the Subsequent Year. To the extent that any Performance Options which did not initially vest at the end of the Missed Year do not

PERIOD OF EXERCISABILITY 

Section 3.1. Vesting and Commencement of Exercisability 

(a) So long as the Optionee continues to be employed by the Company or any of its Subsidiaries through the relevant vesting date, the Option
shall vest and become exercisable as follows: 

  
 -3- 








 (i) Performance Option. 

(A) Forty percent (40%) of the Units subject to Option shall be eligible to vest and become exercisable based on the Company’s
performance as specified in this paragraph (the “Performance Options”). In the event that the Company achieves the revenue and adjusted cash flow targets as set forth in
https://gdc/HumanResources/OptionsandEquity/tabid/758/Default.aspx (the “Annual Performance Target”) for a given Fiscal Year (or portion thereof) as reasonably determined in good faith by the Committee, the percentage of the
Performance Options set forth next to such Fiscal Year (or portion thereof) in the table below shall vest and become exercisable as of the applicable Determination Date. The Fiscal Years on which the vesting of the Performance Options are based will
be determined by the Committee and will be as indicated on the Employee’s Master Signature Page. 
  

			
	 Applicable Performance Period
	  	 Percentage of Units Subject to Performance
Options
Eligible to Vest and Become Exercisable

	 End of Fiscal Year 1
	  	20%
	 End of Fiscal Year 2
	  	20%
	 End of Fiscal Year 3
	  	20%
	 End of Fiscal Year 4
	  	20%
	 End of Fiscal Year 5
	  	20%

 (B) Notwithstanding the foregoing, in the event that either or both component(s) of the Annual Performance
Target is not achieved in a particular Fiscal Year (a “Missed Year”), then that portion of the Performance Option that was eligible to vest and become exercisable but failed to so vest and become exercisable due to the
Company’s failure to achieve either or both component(s) of the Annual Performance Target for such Missed Year shall be eligible to vest and become exercisable at the end of the Fiscal Year immediately following the Missed Year (the
“Subsequent Year”) as provided in this paragraph, but only if the Optionee continues to be employed by the Company or any of its Subsidiaries as of the end of the Subsequent Year. In the event that, in the Subsequent Year, the
Company exceeds the target for either or both of the component(s) of the Annual Performance Target for such Subsequent Year, then the amount of such excess may be added to the amount achieved with respect to the applicable component of the Annual
Performance Target in the Missed Year. If, after giving effect to the addition(s) contemplated by the immediately preceding sentence, both components of the Annual Performance Target are satisfied for the Missed Year, the Performance Options
eligible to have vested and become exercisable in the Missed Year shall vest and become exercisable as of the end of the Subsequent Year. To the extent that any Performance Options which did not initially vest at the end of the Missed Year do not
vest at the end of the Subsequent Year, such Performance Options shall expire as of the end of such Subsequent Year without consideration.

	  	20%
	 Upon the fifth anniversary of the Grant Date
	  	20%

 (B) Notwithstanding Section 3.1(a)(ii)(A) above, to the extent that Time Options do not
accelerate upon a Change in Control pursuant to Section 3.1(c) and remain outstanding following a Change in Control, in the event that the Optionee’s employment is terminated by the Company (or its successor) without Cause or by the
Optionee for Good Reason within 90 days before, or on 18 months after a Change in Control, any then unvested Time Options will become immediately vested and exercisable. 

(b) As a condition of receiving any Options, the Optionee hereby waives any and all rights the Optionee currently has to become vested in any
unvested equity awards of the Company or its Affiliates upon any termination of employment pursuant to any agreement or arrangement entered into prior to the date hereof. 

(c) Effect of Change in Control. Notwithstanding any provision of Section 3.1(a) above, upon the earlier occurrence of a
Change in Control, so long as the Optionee remains employed with the Company or its Subsidiaries through the date of such Change in Control, then any unvested portion of the Time Option and the Performance Option shall become immediately vested and
exercisable as to 100% of the Units subject to such Unit Option immediately prior to the Change in Control if, as a result of such Change in Control, (x) the Sponsors achieve an internal rate of return (determined on a fully diluted basis,
assuming inclusion of all Units underlying all then outstanding Awards and any other outstanding options, warrants or other rights to acquires Units) of at least 25% or (y) the Sponsors earn at least 3.0 times the purchase price of the GD
Equity Interests acquired, directly or indirectly, by the Sponsors (subject to adjustment by the Committee to the extent any

adjustment to the Options occurs pursuant to Section 8 of the Plan), in each case of clause (x) and (y), based on cash received by the Sponsors on a cumulative basis (excluding tax
distributions and after deduction for any applicable transaction expenses). 
 (d) Notwithstanding the foregoing, no portion of the Option
shall vest and become exercisable as to any additional Units (which portion has not otherwise vested and become exercisable in accordance with Sections 3.1(a) or (c) above) following the termination of employment of the Optionee with the
Company and its Subsidiaries for any reason (other than provided for in Section 3.1(a)(ii)(B) above), and the portion of the Option that is unvested and unexercisable as of the Optionee’s termination of employment with the Company and its
Subsidiaries shall immediately expire upon such termination without consideration.

consideration, upon the first to occur of the following events:

 NETHERLANDS 

Notification for Dutch Employees 
 The Optionee should be aware
of the Dutch insider trading rules, which may affect the sale of Units acquired under the Plan. In particular, the Optionee may be prohibited from effecting certain Unit transactions if the Optionee has insider information regarding the Company.
Below is a discussion of the applicable restrictions. The Optionee is advised to read the discussion carefully to determine whether the insider rules could apply to the Optionee. If it is uncertain whether the insider rules apply, the Company
recommends that the Optionee consult with a legal advisor. The Company cannot be held liable if the Optionee violates the Dutch insider trading rules. The Optionee is responsible for ensuring your compliance with these rules. 

Prohibition Against Insider Trading 
 Dutch securities
laws prohibit insider trading. The regulations are based upon the European Market Abuse Directive and are stated in section 5:56 of the Dutch Financial Supervision Act (Wet op het financieel toezicht or Wft) and in section 2 of the Market Abuse
Decree (Besluit marktmisbruik Wft). For further information you are referred to the website of the Authority for the Financial Markets (AFM); http://www.afm.nl/~/media/Files/brochures/2012/insider-dealing.ashx. 

Given the broad scope of the definition of inside information, certain employees of the Company working at its Dutch Affiliate may have inside information and

notification above and acknowledges that it is the Optionee’s responsibility to comply with the Dutch insider trading rules, as discussed herein. 

Taxation 
 The difference between the exercise price for which
Units can be acquired and the fair market value of the Units at the time of exercise is treated as income out of employment for employees working in the Netherlands as stipulated in section 10a of the Dutch Wage Tax Act 1964. The Dutch employing
company of these employees is entitled to withhold wage tax and social security premiums as described in section 4.7. of the Form of Unit Option Agreement. Any income out of exercise of the options will be reported to the Dutch Tax Authorities by
the Dutch employing Company under mandatory law.

 NETHERLANDS 

Notification for Dutch Employees 
 The Optionee should be
aware of the Dutch insider trading rules, which may affect the sale of Units acquired under the Plan. In particular, the Optionee may be prohibited from effecting certain Unit transactions if the Optionee has insider information regarding the
Company. Below is a discussion of the applicable restrictions. The Optionee is advised to read the discussion carefully to determine whether the insider rules could apply to the Optionee. If it is uncertain whether the insider rules apply, the
Company recommends that the Optionee consult with a legal advisor. The Company cannot be held liable if the Optionee violates the Dutch insider trading rules. The Optionee is responsible for ensuring your compliance with these rules. 

Prohibition Against Insider Trading 
 Dutch
securities laws prohibit insider trading. The regulations are based upon the European Market Abuse Directive and are stated in section 5:56 of the Dutch Financial Supervision Act (Wet op het financieel toezicht or Wft) and in section 2 of the Market
Abuse Decree (Besluit marktmisbruik Wft). For further information you are referred to the website of the Authority for the Financial Markets (AFM); http://www.afm.nl/~/media/Files/brochures/2012/insider-dealing.ashx. 

Given the broad scope of the definition of inside information, certain employees of the Company working at its Dutch Affiliate may have inside information and

notification above and acknowledges that it is the Optionee’s responsibility to comply with the Dutch insider trading rules, as discussed herein. 

Taxation 
 The difference between the exercise price for
which Units can be acquired and the fair market value of the Units at the time of exercise is treated as income out of employment for employees working in the Netherlands as stipulated in section 10a of the Dutch Wage Tax Act 1964. The Dutch
employing company of these employees is entitled to withhold wage tax and social security premiums as described in section 4.7. of the Form of Unit Option Agreement. Any income out of exercise of the options will be reported to the Dutch Tax
Authorities by the Dutch employing Company under mandatory law.
