conditioned upon such surrender may have an Option price lower (or higher) than the Option price of the surrendered Option, may cover the same (or a lesser or greater) number of shares as the surrendered Option, may contain such other terms as the
Board deems appropriate, and shall be exercisable in accordance with its terms, without regard to the number of shares, price, period of exercisability or any other term or condition of the surrendered Option.

 TERMS OF
OPTIONS

within the meaning of Section 422 of the Code. 

  
 6 

 Section 4.2 Exercisability of Options 

(a) Each Option shall become exercisable according to the terms of the applicable Stock Option Agreement; provided, however, that
by a resolution adopted after an Option is granted the Committee (or the Board in the case of Options granted to Independent Directors) may, on such terms and conditions as it may determine to be appropriate, accelerate the time at which such Option
or any portion thereof may be exercised. 
 (b) Except as otherwise provided in the applicable Stock Option Agreement, no portion of an
Option which is unexercisable at Termination of Services shall thereafter become exercisable. 
 (c) To the extent that the aggregate Fair
Market Value of stock with respect to which “incentive stock options” (within the meaning of Section 422 of the Code, but without regard to Section 422(d) of the Code) are exercisable for the first time by an Optionee during any
calendar year (under the Plan and all other incentive stock option plans of the Company or any Subsidiary thereof) exceeds $100,000, such options shall be treated and taxable as Non-Qualified Stock Options.
The rule set forth in the preceding sentence shall be applied by taking options into account in the order in which they were granted, and any stock certificate issued upon exercise of options shall designate whether such stock was acquired upon
exercise of an Incentive Stock Option. For purposes of these rules, the Fair Market Value of stock shall be determined as of the date of grant of the Option granted with respect to such stock. 

Section 4.3 Option Price. The price of the shares subject to each Option shall be set by the Committee (or the
Board in the case of Options granted to Independent Directors); provided, however, that in the case of an Incentive Stock Option, the price per share shall be not less than 100% of the Fair Market Value of such shares on the date such
Option is granted; and provided, further, that in the case of an Incentive Stock Option granted to an individual then owning (within the meaning of Section 424(d) of the Code) more than 10% of the total combined voting power of
all classes of stock of the Company or any of its Subsidiaries, the price per share shall not be less than 110% of the Fair Market Value of such shares on the date such Incentive Stock Option is granted.

meaning of Section 424(d) of the Code), at the time the Incentive Stock Option was granted, more than 10% of the total combined voting power of all classes of stock of the Company or any Subsidiary thereof, the expiration of five years from the
date the Incentive Stock Option was granted. 
 Section 4.5 At-Will
Services. Nothing in the Plan or in any Stock Option Agreement hereunder shall confer upon any Optionee any right to continue in the employ of, or service as a Consultant or Director to, the Company or any Subsidiary thereof, or shall interfere
with or restrict in any way the rights of the Company and any Subsidiary thereof, which are hereby expressly reserved, to discharge any Optionee at any time for any reason whatsoever, with or without cause, except to the extent expressly provided
otherwise in a written agreement between the Optionee and the Company or any Subsidiary thereof.

shares. 
 Section 5.3 Manner of Exercise. An exercisable Option, or any exercisable portion thereof, may be

means of payment approved by the Committee) of all amounts necessary to satisfy any and all federal, state and local tax withholding requirements arising in connection with the exercise of the Option; provided that the Committee may, in its
reasonable discretion, allow the Optionee to satisfy the withholding tax obligations arising in connection with the exercise of any Option under the Plan by electing to have the Company withhold from the Common Stock to be issued that number of
shares of Common Stock having a Fair Market Value equal to the amount required to be withheld (based on minimum applicable statutory withholding rates), determined on the date that the amount of tax to be withheld is determined; 

(e) Such representations and documents as the Committee (or the Board in the case of Options granted to Independent Directors) deems necessary
or advisable to effect compliance with all applicable provisions of the Securities Act, Exchange Act and any other federal or state securities laws or regulations. The Committee (or the Board in the case of Options granted to Independent Directors)
may, in its sole discretion, also take whatever additional actions it deems appropriate to effect such compliance including, without limitation, placing legends on share certificates and issuing stop-transfer orders to transfer agents and

set forth in Section 5.4. 
 Section 5.6 Transfer Restrictions. Shares acquired upon exercise of an
Option shall be subject to the terms and conditions of the Stockholders Agreement. In addition, the Committee (or the Board in the case of Options granted to Independent Directors), in its sole discretion, may impose further restrictions on the

duties of the Committee under the Plan except with respect to matters which under Rule 16b-3 or Section 162(m) of the Code (in each case, to the extent applicable), or any regulations or rules issued
thereunder, are required to be determined in the sole discretion of the Committee. The governance of the Committee shall be subject to the charter of the Committee as approved by the Board. 

Section 6.2 Delegation of Authority. The Committee may, but need not, from time to time delegate some or all
of its authority to grant Options under the Plan to a committee or subcommittee consisting of one or more members of the Committee or of one or more Officers; provided, however, that the Committee may not delegate its authority to
grant Options to individuals (a) who are subject on the date of the grant to the reporting rules under Section 16(a) of the Exchange Act, (b) whose compensation the Committee determines is, or may become, subject to the deduction
limitations set forth in Section 162(m) of the Code or (c) who are Officers who are delegated authority by the Committee hereunder. Any delegation hereunder shall be subject to the restrictions and limits that the Committee specifies at

conduct the general administration of the Plan in accordance with its provisions. The Committee shall have the power to interpret the Plan and the Options and to adopt such rules for the administration, interpretation and application of the Plan as
are consistent therewith and to interpret, amend or revoke any such rules. Notwithstanding the foregoing, the full Board, acting by a majority of its members in office, shall conduct the general administration of the Plan with respect to Options
granted to Independent Directors. Any such interpretations and rules in regard to Incentive Stock Options shall be consistent with the terms and conditions applicable to “incentive stock options” within the meaning of Section 422 of
the Code. All determinations and decisions made by the Committee under any provision of the Plan or of any Option granted thereunder shall be final, conclusive and binding on all persons. 

Section 6.4 Compensation, Professional Assistance, Good Faith Actions. The members of the Committee shall
receive such compensation, if any, for their services hereunder as may be determined by the Board. All expenses and liabilities incurred by the members of the Committee or the Board in connection with the administration of the Plan shall be borne by
the Company. The Committee or the Board may employ attorneys, consultants, accountants, appraisers, brokers or other persons. The Committee, the Company and the Officers and Directors shall be entitled to rely upon the advice, opinions or valuations
of any such persons. All actions taken and all interpretations and determinations made by the Committee and the Board in good faith shall be final and binding upon all Optionees, the Company and all other interested persons. No member of the Board

Company or any Affiliate, or of changes in applicable laws, regulations, or accounting principles, the Committee (or the Board in the case of options granted to Independent Directors), in its sole discretion, is hereby authorized to take any one or
more of the following actions whenever the Committee (or the Board in the case of Options granted to Independent Directors) determines that such action is appropriate in order to prevent dilution or enlargement of the benefits or potential benefits
intended to be made available under the Plan or with respect to any Option under this Plan, to facilitate such Corporate Event or transactions or events or to give effect to such changes in laws, regulations or principles:

securities, or other property equal to the amount that could have been attained upon the exercise of the vested portion of such Option (and such additional portion of the Option as the Board or
Committee may determine) immediately prior to the occurrence of such transaction or event (and, for the avoidance of doubt, if as of the date of the occurrence of such transaction or event the Committee (or the Board in the case of Options granted
to Independent Directors) determines in good faith that no amount would have been obtained upon the exercise of such Option, then the Option may be terminated by the Company without payment), or (B) the replacement of such vested (and other)
portion of such Option with other rights, cash, securities or other property selected by the Committee (or the Board in the case of Options granted to Independent Directors) in its sole discretion;

granted to Independent Directors) may provide, either by the terms of the applicable Stock Option Agreement or by action taken prior to the occurrence of such Corporate Event, that for a specified period of time prior to such Corporate Event, such
Option shall be exercisable as to all shares covered thereby or a specified portion of such shares, notwithstanding anything to the contrary in this Plan or the applicable Stock Option Agreement; 

(iv) In its sole discretion, and on such terms and conditions as it deems appropriate, the Committee (or the Board in the case of Options
granted to Independent Directors) may provide, either by the terms of the applicable Stock Option Agreement or by action taken prior to the occurrence of such Corporate Event, that upon such event, such Option (or any portion thereof) shall be
assumed by the successor or survivor corporation, or a parent or Subsidiary thereof (including without limitation any common parent of the Company and any other company or companies), or shall be substituted for by similar options, rights or awards
covering the stock of the successor or survivor corporation, or a parent or Subsidiary thereof (including without limitation any common parent of the Company and any other company or companies), with appropriate adjustments as to the number and kind
of shares and prices; 
 (v) In its sole discretion, and on such terms and conditions as it deems appropriate, the Committee (or the Board
in the case of Options granted to Independent Directors) may make adjustments in the number and type of shares of Common Stock (or other securities or property) subject to outstanding Options (or any portion thereof) and/or in the terms and
conditions of (including the exercise price), and the criteria included in, outstanding Options and Options which may be granted in the future; and

 (c) In connection with the occurrence of any Equity Restructuring: 

  
 13 

 (i) The number and type of securities subject to each outstanding Option and the exercise
price thereof, if applicable, shall be equitably adjusted. The adjustments provided under this Section 7.1(c)(i) shall be nondiscretionary and shall be final and binding on the affected Optionee and the Company. 

(ii) The Committee (or the Board, in the case of Options granted to Independent Directors) shall make such equitable adjustments, if any, as
the Committee (or the Board, in the case of Options granted to Independent Directors) in its discretion may deem appropriate to reflect such Equity Restructuring with respect to the aggregate number and kind of shares of Common Stock (or other
securities or property) that may be issued under the Plan (including, but not limited to, adjustments of the limitation set forth in Section 2.1). 

(d) Subject to Section 7.1(e), the Committee (or the Board in the case of Options granted to Independent Directors) may, in its sole
discretion, include such further provisions and limitations in any Stock Option Agreement as it may deem equitable and in the best interests of the Company and its Affiliates. 

(e) With respect to Incentive Stock Options, no adjustment or action described in this Section 7.1 or in any other provision of the Plan
shall be authorized to the extent that such adjustment or action would cause the Plan to violate Section 422(b)(1) of the Code or any successor provisions thereto, unless the Committee determines that the Plan and/or the Options are not to
comply with Section 422(b)(1) of the Code. If any rounding of the number of shares of Common Stock subject to any Option is required in connection with any adjustment or action described in this Section 7.1, the number of shares of Common
Stock subject to such Option shall always be rounded down to the next higher whole number.

results in a dilution of ownership of the Common Stock affecting all of the Company’s stockholders in the same manner.

for the debts, contracts or engagements of the Optionee or his or her successors in interest or shall be subject to disposition by transfer, alienation, anticipation, pledge, encumbrance, assignment or any other means whether such disposition be
voluntary or involuntary or by operation of law, by judgment, levy, attachment, garnishment or any other legal or equitable proceedings (including bankruptcy), and any attempted disposition thereof shall be null and void and of no effect;
provided, however, that nothing in this Section 7.2 shall prevent transfers by will or by the applicable laws of descent and distribution. 

  
 14 

 Section 7.3 Amendment, Suspension or Termination of the
Plan. The Plan may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the Board or the Committee. However, without stockholder approval within twelve (12) months before or after
such action, no action of the Board or the Committee may, except as provided in Section 7.1, increase any limit imposed in Section 2.1 on the maximum number of shares which may be issued on exercise of Options, reduce the minimum Option
price requirements of Section 4.3, or extend the limit imposed in this Section 7.3 on the period during which Options may be granted. Except as provided by Section 7.1, neither the amendment, suspension nor termination of the Plan
shall, without the consent of the holder of the Option, impair any rights or obligations under any Option theretofore granted (other than in a de minimis manner). No Option may be granted during any period of suspension nor after termination of the
Plan, and in no event may any Option be granted under this Plan after the expiration of ten years from the date the Plan is adopted by the Board.

grant or assumption of options in connection with the acquisition by purchase, lease, merger, consolidation or otherwise, of the business, stock or assets of any corporation, firm or association. 

Section 7.5 Approval of Plan by Stockholders. This Plan will be submitted for the approval of the
Company’s stockholders within twelve (12) months after the date of the Board’s initial adoption of this Plan. No Option may be exercised to any extent by anyone unless and until the Plan is so approved by the stockholders, and if such
approval has not been obtained by the end of said 12-month period, the Plan and all Options theretofore granted shall thereupon be canceled and become null and void. 

Section 7.6 Titles. Titles are provided herein for convenience only and are not to serve as a basis for
interpretation or construction of the Plan. 
 Section 7.7 Conformity to Securities Laws. The Plan is
intended to conform to the extent necessary with all provisions of (a) the Securities Act and the Exchange Act and any and all regulations and rules promulgated by the Securities and Exchange Commission thereunder and (b) any applicable
state and local securities laws and any and all regulations and rules promulgated by any applicable state or local regulatory authority thereunder, in each case to the extent the Company or any Optionee is subject to the provisions thereof.
Notwithstanding anything herein to the contrary, the Plan shall be administered, and Options shall be granted and may be exercised, only in such a manner as to conform to such laws, rules and regulations. To the extent permitted by applicable law,
the Plan and Options granted hereunder shall be deemed amended to the extent necessary to conform to such laws, rules and regulations.

accordance with and governed by the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof, or principles of conflicts of law of any other jurisdiction which could cause the application of the laws of
any jurisdiction other than the State of Delaware. 
 Section 7.9 Severability. In the event any portion of
the Plan or any action taken pursuant thereto shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of the Plan, and the Plan shall be construed and enforced as if the illegal or invalid
provisions had not been included, and the illegal or invalid action shall be null and void. 

  
 15 

 Section 7.10 Section 409A. To the extent
applicable, the Plan and Stock Option Agreements shall be interpreted in accordance with Section 409A of the Code and the Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of the
Plan to the contrary, in the event that the Committee determines that any Option may be subject to Section 409A of the Code, the Committee may adopt such amendments to the Plan and the applicable Stock Option Agreement or adopt other policies
and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions, that the Committee determines are necessary or appropriate to (a) exempt the Option from Section 409A of the Code and/or
preserve the intended tax treatment of the benefits provided with respect to the Option, or (b) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance and thereby avoid the application of
penalty taxes under such Section 409A. Notwithstanding anything herein to the contrary, no provision of the Plan shall be interpreted or construed to transfer any liability for failure to comply with the requirements of Section 409A of the
Code from any Optionee or other Person to the Company or any of its Affiliates, employees or agents.

and cumulative installments; provided that the Optionee remains continuously employed or engaged in active service by the Company or any of its Subsidiaries (and no Termination of Services occurs) from the Grant Date through such date, as
follows: 
 (i) The first installment shall consist of 12% of the shares covered by the Option (20% of the Time-Vesting Option) and shall
become exercisable on [____]; 
 (ii) The second installment shall consist of an additional 12% of the shares covered by the Option (20% of
the Time-Vesting Option) and shall become exercisable on [____]; 
 (iii) The third installment shall consist of an additional 12% of the

Measurement Date, a portion of the Performance-Vesting Option equal to the portion of the Time-Vesting Option that has already vested as of the date of such Qualifying Termination shall become vested and exercisable such that, immediately following
such vesting, an equivalent percentage of the Time-Vesting Option and the Performance-Vesting Option shall be vested and exercisable. No portion of the Performance-Vesting Option which is unexercisable immediately following the Measurement Date
(after taking into account any vesting that occurs pursuant to Section 3.1(b) on any Measurement Date) shall thereafter become exercisable (and such unexercisable portion shall be forfeited as of immediately following the Measurement Date).

(b) The 90th day following the date of the Optionee’s Termination of Services for any reason other than (i) termination by the
Company for Cause or (ii) a Qualifying Termination; or 

  
 6 

 (c) Notwithstanding the provisions of Section 3.1, in the event of the Optionee’s
Termination of Services by the Company for Cause the Optionee shall, immediately prior to such Termination of Services (and subject to such Termination of Services), forfeit the Option, whether vested or unvested; in addition, if the Optionee
breaches this Agreement, the Stockholders Agreement or any Employment Agreement following the Optionee’s Termination of Services in a manner that would constitute Cause under subsection (g) of the definition thereof (an “Agreement
Breach”) and the Optionee does not cure such Agreement Breach within fifteen (15) days after written notice thereof to the Optionee from the Company or any of its Subsidiaries, the Optionee shall, immediately following the expiration
of such cure period, forfeit the Option, whether vested or unvested (assuming the Optionee fails to timely cure the applicable Agreement Breach); or 

(d) In the case of a Qualifying Termination, the expiration of one year from the date of the Optionee’s Termination of Services. 

Section 3.4 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; provided, however, that each partial exercise shall be for not less than 10 shares of Common Stock and
shall be for whole shares of Common Stock only. 
 Section 3.5 Exercise of Option. The exercise of the
Option shall be governed by the terms of this Agreement and the terms of the Plan, including, without limitation, the provisions of Article V of the Plan.

 Section 4.3 Proprietary Information. The Optionee agrees
that the Optionee shall not use for the Optionee’s own purpose or for the benefit of any person or entity (including, without limitation, a Competing Business) other than the Company or its shareholders or affiliates, nor shall the Optionee
otherwise disclose to any individual or entity at any time while the Optionee is employed by the Company or thereafter any Proprietary Information of the Company unless such disclosure (a) has been authorized by the Board; (b) is
reasonably required within the course and scope of the Optionee’s employment with the Company; or (c) is required by law, a court of competent jurisdiction or a governmental or regulatory agency. 

Section 4.4 Surrender of Records. The Optionee agrees that, upon Termination of Services, the Optionee shall
not retain and shall promptly surrender to the Company all correspondence, memoranda, files, manuals, financial, operating or marketing records, magnetic tape, or electronic or other media of any kind which may be in the Optionee’s possession
or under the Optionee’s control or accessible to the Optionee which contain any Proprietary Information. 

Section 4.5 Inventions and Patents. 

(a) The Optionee agrees that all inventions, innovations, trade secrets, patents and processes in any way relating, directly or indirectly, to
the Company’s business developed by the Optionee alone or in conjunction with others (“Inventions”) at any time during the Optionee’s employment by the Company shall belong to the Company. The Optionee will use the
Optionee’s best efforts to perform all actions reasonably requested by the Board to establish and confirm such ownership by the Company. Notwithstanding the foregoing, the Optionee understands that this Agreement does not require assignment of
any Invention to the extent that such Invention qualifies for protection under Section 2870 of the California Labor Code, 765 Ill. Comp. Stat. Ann. 1060/2, Section 44-130 of the Kansas Statutes,
Section 181.78 of the 2016 Minnesota Statutes or Section 49.44.140 of the Revised Code of Washington, the current text of each of which is attached hereto as Exhibit B. 

(b) The Optionee acknowledges that the Company has provided the Optionee with the following notice of immunity rights in compliance with the
requirements of the Defend Trade Secrets Act of 2016: (i) the Optionee shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of Proprietary Information that is made in confidence to a Federal,
State, or local government official or to an attorney solely for the purpose of reporting or investigating a suspected violation of law, (ii) the Optionee shall not be held criminally or civilly liable under any Federal or State trade secret
law for the disclosure of Proprietary Information that is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal and (iii) if the Optionee files a lawsuit for retaliation by the Company
for reporting a suspected violation of law, the Optionee may disclose the Proprietary Information to his or her attorney and use the Proprietary Information in the court proceeding, if the Optionee files any document containing the Proprietary
Information under seal, and does not disclose the Proprietary Information, except pursuant to court order.

 Section 4.6
Non-Disparagement. The Optionee agrees not to disparage the Company, any of its products or practices, any of its directors, officers, agents, representatives, employees or affiliates, either orally or
in writing, at any time; provided that the Optionee shall not be required to make any untruthful statement or to violate any law. 

Section 4.7 Limited Exceptions. Notwithstanding anything to the contrary in Section 4, (a) to the extent
this Section 4 is subject to the internal laws of the State of California, Section 4.1 and 4.2(c) shall not apply and the word “hire” in Section 4.2(b) shall be replaced with “solicit for the purpose of employing”;
(b) to the extent this Section 4 is subject to the internal laws of the State of North Dakota, Section 4.1 and 4.2(c) shall not apply; (c) to the extent this Section 4 is subject to the internal laws of the State of Oklahoma,
Section 4.1 shall not apply and Section 4.2 shall only apply to limit the Optionee’s direct solicitation of the Company’s established customers for purposes of sale of goods or services; (d) to the extent this Section 4
is subject to the internal laws of the State of Illinois or North Carolina, Section 4.2(c) shall only apply to limit inducing or attempting to induce persons that the Optionee has had business contact with while employed at the Company; and
(e) to the extent this Section 4 is subject to the internal laws of the State of Missouri, Section 4.2(a) and (b) shall not apply to the extent the Optionee solicits secretarial or clerical employees of the Company. 

Section 4.8 Definition of the Company. For purposes of this Article IV, the term “Company”
shall include Hotshine Holdings, Inc. and any and all of its subsidiaries and joint ventures as the same may exist from time to time. 

Section 4.9 Enforcement. The parties hereto agree that the time, duration and area for which the covenants
set forth in this Article IV are to be effective are reasonable. In the event that any court or arbitrator determines that the time period or the area, or both of them, are unreasonable and that any of the covenants are to that extent unenforceable,
the parties hereto agree that such covenants will remain in full force and effect, first, for the greatest time period, and second, in the greatest geographical area that would not render them unenforceable. The parties intend that this Article IV
will be deemed to be a series of separate covenants, one for each and every county of each and every state of the United States of America. The Optionee agrees that damages are an inadequate remedy for any breach of the covenants in this Article IV
and that the Company will, whether or not it is pursuing any potential remedies at law, be entitled to equitable relief in the form of preliminary and permanent injunctions without bond or other security upon any actual or threatened breach of this
Article IV. The Optionee acknowledges and agrees that this Article IV (a) is ancillary to a valid employment relationship with the Company or one of its Subsidiaries, (b) is reasonably necessary to protect the Company’s legitimate
business interest (including, without limitation, the Company’s customer relationships and Proprietary Information), and (c) does not unreasonably restrict the Optionee’s right to work in his chosen profession. Notwithstanding
anything to the contrary, nothing herein is intended to or will prohibit the Optionee from filing a charge with, reporting possible violations of law or regulation to, participating in any investigation by, cooperating with, or communicating
directly with, or providing information in confidence to, any governmental entity or making other disclosures that are protected under the whistleblower provisions of applicable law or regulation.

 ARTICLE V. 

REPURCHASE RIGHT. 

Section 5.1 Repurchase Right. In the event of an Agreement Breach (which, for avoidance of doubt, includes
but is not limited to any violation of Article IV of this Agreement), the Company shall have the right to purchase all or a portion of the shares of Common Stock issued upon exercise of the Option (the “Option Shares”) held by such
Optionee and any other Person to whom such Optionee has transferred such shares, at an aggregate purchase price equal to the lesser of (x) the exercise price paid by such Optionee in connection with the exercise of the Option and (y) the
Fair Market Value thereof (the “Repurchase Right”). 
 Section 5.2 Repurchase Notice and
Closing. At any time following an Agreement Breach, the Company may exercise the Repurchase Right by delivering to the Optionee (or his or her transferee, as applicable) a written notice indicating the Company’s intention to exercise the
Repurchase Right and the amount to be paid to the Optionee in consideration for the repurchase of the Option Shares, which shall be paid in cash, by certified check or by wire transfer of immediately available funds. The closing of any repurchase of
the Option Shares pursuant to this Article V shall occur on a date selected by the Company no later than 60 days following the date of delivery of the Company’s written notice of exercise of the Repurchase Right and, following such closing, the
Optionee (and his or her transferee, if applicable) shall have no further rights with respect to the Option Shares. 

Section 5.3 Repurchase Delay. Notwithstanding anything to the contrary herein, if the Company requires the
consent of any of its lenders in order to exercise the Repurchase Right pursuant to this Article V and cannot obtain such consent (or can obtain such consent only subject to the imposition by such lender of additional costs, restrictions or other
obligations on the Company or any of its Affiliates), the Company may notify the Optionee in writing of such failure to obtain consent and defer the closing of the repurchase of such Option Shares until such time as such consent is obtained or is no
longer required. 
 Section 5.4 Termination. The provisions of this Article V shall terminate upon the
consummation of an Initial Public Offering. 
 ARTICLE VI. 

OTHER PROVISIONS 

Section 6.1 Not a Contract of Employment or Services. Nothing in this Agreement or in the Plan shall confer
upon the Optionee any right to continue in the employ or engagement of the Company or any of its Subsidiaries or shall interfere with or restrict in any way the rights of the Company or its Subsidiaries, which are hereby expressly reserved, to
discharge the Optionee at any time for any reason whatsoever, with or without Cause, except as may otherwise be provided by any written agreement entered into by and between the Company and the Optionee. 

Section 6.2 Shares Subject to Plan and Stockholders Agreement; Entire Agreement. The Optionee acknowledges
that any shares acquired upon exercise of the Option are subject to the terms of the Plan and the Stockholders Agreement. The terms of this Agreement are intended by the parties to be the final expression of their agreement with respect to the
subject matter hereof and may not be contradicted by evidence of any prior or contemporaneous agreement. The parties further intend that this Agreement (together with the Plan and the Stockholders Agreement) shall constitute the complete and
exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement. For the avoidance of doubt, Article V of this Agreement is
in addition to, and does not terminate, amend or modify, any repurchase rights with respect to the Option Shares under the Stockholders Agreement.

 Section 6.3 Construction. This Agreement shall be
administered, interpreted and enforced under the internal laws of the State of Delaware, without regard to the principles of conflicts of law thereof, or principles of conflicts of law of any other jurisdiction which could cause the application of
the laws of any jurisdiction other than the State of Delaware. Notwithstanding the foregoing, (a) if Optionee primarily resides in California, Section 4 shall be administered, interpreted and enforced under the internal laws of the State
of California, without regard to the principles of conflicts of law thereof, or principles of conflicts of law of any other jurisdiction which could cause the application of the laws of any jurisdiction other than the State of California and
(b) if, pursuant to applicable state law, Section 4 is otherwise required to be administered, interpreted and enforced under the internal laws of a state other than the State of Delaware, Section 4 will be administered, interpreted
and enforced under the internal laws of such state. 
 Section 6.4 Conformity to Securities Laws. The
Optionee acknowledges that the Plan is intended to conform to the extent necessary with all provisions of the Securities Act and the Exchange Act and any and all regulations and rules promulgated thereunder by the Securities and Exchange Commission,
including without limitation Rule 16b-3. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Option is granted and may be exercised, only in such a manner as to conform to
such laws, rules and regulations. To the extent permitted by applicable law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations. 

Section 6.5 Amendment, Suspension and Termination. The Option may be wholly or partially amended or otherwise
modified, suspended or terminated at any time or from time to time by the Committee or the Board; provided that the Optionee’s consent shall be required with respect to any such action unless (a) the Committee determines that the
action, taking into account any related action, would not materially and adversely affect the Optionee or (b) such change is permitted under Section 7.1 of the Plan or Section 6.6 or 6.7 of this Agreement. 

Section 6.6 Section 409A. To the extent applicable, this Agreement shall be interpreted in accordance with
Section 409A of the Code and Department of Treasury regulations and other interpretive guidance issued thereunder. Notwithstanding any provision of this Agreement to the contrary, in the event that the Committee determines that this Option may
be subject to Section 409A of the Code, the Committee may adopt such amendments to this Agreement or adopt other policies and procedures (including amendments, policies and procedures with retroactive effect), or take any other actions that the
Committee determines are necessary or appropriate to (a) exempt the Option from Section 409A of the Code and/or preserve the intended tax treatment of the benefits provided with respect to the Option, or (b) comply with the
requirements of Section 409A of the Code and related Department of Treasury guidance and thereby avoid the application of penalty taxes under such Section 409A. Notwithstanding anything herein to the contrary, in no event shall any
liability for failure to comply with the requirements of Section 409A of the Code be transferred from the Optionee or any other Person to the Company or any of its Affiliates, employees or agents pursuant to the terms of this Agreement or
otherwise. 

  
 11 

 Section 6.7 Stockholder Approval. 

(a) Except as otherwise provided in Section 6.7(b), in the event that the Company determines that any right to receive the Option, payment
or other benefit under this Agreement (including, without limitation, the acceleration of the vesting and/or exercisability of the Option and taking into account the effect of this Section) or any employment agreement by and between the Optionee and
the Company, to or for the benefit of the Optionee (the “Payments”), would, in whole or part when aggregated with any other right, payment or benefit to or for the Optionee under all other agreements or benefit plans of the Company,
be nondeductible by the Company (or other person making such payment or providing such benefit) as a result of Section 280G of the Code and/or would subject the Optionee to the excise tax imposed by Section 4999 of the Code (the
“Excise Tax”) then, to the extent necessary to make the Payments deductible and to exempt the Payments from the Excise Tax (but only to such extent and after taking into account any reduction in the Payments relating to
Section 280G of the Code under any other plan, arrangement or agreement), the Option or any other right, payment or benefit under this Agreement shall not become exercisable, vested or paid. 

(b) Notwithstanding any other provision of this Agreement, the provisions of Section 6.7(a) shall not apply to reduce the Payments if the
Payments that would otherwise be nondeductible under Section 280G of the Code and/or would subject the Optionee to the Excise Tax are disclosed to and approved by the Company’s stockholders in accordance with Section 280G(b)(5)(B) of
the Code and the Department of Treasury regulations thereunder. 
 (c) The Company shall use commercially reasonable efforts to prepare and
deliver to its stockholders the disclosure required by Section 280G(b)(5)(B) of the Code with respect to the Payments and to obtain the approval of the Company’s stockholders pursuant to Section 6.7(b).
