 Exhibit 10.1 

INDEMNITY AGREEMENT 
 THIS
INDEMNITY AGREEMENT (this “Agreement”) dated as of                     
      , 20    , is made by and between Genprex, Inc., a Delaware corporation (the “Company”), and
                             (“Indemnitee”). 

RECITALS 
 A. The
Company desires to attract and retain the services of highly qualified individuals as directors, officers, employees and agents. 
 B.
The Company’s Amended and Restated Bylaws (the “Bylaws”) require that the Company indemnify its directors and officers, and empowers the Company to indemnify its employees and other agents, as authorized by the
Delaware General Corporation Law, as amended (the “Code”), under which the Company is organized and such Bylaws expressly provide that the indemnification provided therein is not exclusive and contemplates that the Company
may enter into separate agreements with its directors, officers and other persons to set forth specific indemnification provisions. 
 C.
Indemnitee does not regard the protection currently provided by applicable law, the Bylaws, the Company’s other governing documents, and available insurance as adequate under the present circumstances, and the Company has determined that
Indemnitee and other directors, officers, employees and agents of the Company may not be willing to serve or continue to serve in such capacities without additional protection. 

D. The Company desires and has requested Indemnitee to serve or continue to serve as a director, officer, employee or agent of the
Company, as the case may be, and has proffered this Agreement to Indemnitee as an additional inducement to serve in such capacity. 
 E.
Indemnitee is willing to serve, or to continue to serve, as a director, officer, employee or agent of the Company, as the case may be, if Indemnitee is furnished the indemnity provided for herein by the Company. 

AGREEMENT 
 NOW
THEREFORE, in consideration of the mutual covenants and agreements set forth herein, the parties hereto, intending to be legally bound, hereby agree as follows: 

1. Definitions.

(ii) is or was serving at the request or for the convenience of, or representing the interests of, the Company or a subsidiary of the Company, as a director, officer, employee, agent, or other fiduciary of a foreign or domestic corporation,
partnership, joint venture, trust or other enterprise. 

 (b) Change in Control. For purposes of this Agreement, a “Change in
Control” shall be deemed to have occurred if (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange
Act”), other than a trustee or other fiduciary holding securities under an employee benefit plan of the Company or a corporation owned directly or indirectly by the stockholders of the Company in substantially the same proportions as
their ownership of stock of the Company, is or becomes the “beneficial owner” (as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company
representing 20% or more of the total voting power represented by the Company’s then outstanding Voting Securities, (ii) individuals who on the date of this Agreement are members of the Board (the “Incumbent Board”)
cease for any reason to constitute at least a majority of the members of the Board (provided, however, that if the appointment or election (or nomination for election) of any new Board member was approved or recommended by a majority vote of the
members of the Incumbent Board then still in office, such new member shall be considered as a member of the Incumbent Board), or (iii) the stockholders of the Company approve a merger or consolidation of the Company with any other corporation,
other than a merger or consolidation which would result in the Voting Securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into Voting Securities of the
surviving entity) at least 80% of the total voting power represented by the Voting Securities of the Company or such surviving entity outstanding immediately after such merger or consolidation, or the stockholders of the Company approve a plan of
complete liquidation of the Company or an agreement for the sale or disposition by the Company of (in one transaction or a series of transactions) all or substantially all of the Company’s assets. 

(c) Expenses. For purposes of this Agreement, the term “Expenses” shall be broadly construed and shall include,
without limitation, all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’, witness, or other professional fees and related disbursements, and other out-of-pocket costs of whatever nature, actually and reasonably incurred by Indemnitee in connection with the investigation, defense or appeal of a proceeding or establishing or enforcing a right to
indemnification under this Agreement, the Code or otherwise. The term “Expenses” shall also include reasonable compensation for time spent by Indemnitee for which he or she is not compensated by the Company or any subsidiary
or third party: (i) for any period during which Indemnitee is not an Agent, in the employment of, or providing services for compensation to, the Company or any subsidiary; and (ii) if the rate of compensation and estimated time involved is
approved by the directors of the Company who are not parties to any action with respect to which Expenses are incurred, for Indemnitee while an Agent of, employed by, or providing services for compensation to, the Company or any subsidiary. 

(d) Independent Counsel. For purposes of this Agreement, the term “Independent Counsel” means a law firm, or a
partner (or, if applicable, member) of such a law firm, that is experienced in matters of corporation law and neither presently is, nor in the past five (5) years has been, retained to represent: (i) the Company or Indemnitee in any matter
material to either such party, or (ii) any other party to the proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not include any person
who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under this Agreement. The Company will
pay the reasonable fees and expenses of the Independent Counsel referred to above and to fully indemnify such counsel against any and all expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement
pursuant hereto. 
 (e) Liabilities. For purposes of this Agreement, the term “Liabilities” shall be broadly
construed and shall include, without limitation, judgments, damages, deficiencies, liabilities, losses, penalties, excise taxes, fines, assessments and amounts paid in settlement, including any interest and any federal, state, local or foreign taxes

“proceeding” shall be broadly construed and shall include, without limitation, any threatened, pending, or completed action, suit, claim, counterclaim, cross claim, arbitration, mediation, alternate dispute resolution
mechanism, investigation, inquiry, administrative hearing, or any other actual, threatened or completed proceeding, whether brought in the right of the Company or otherwise and whether of a civil, criminal, administrative or investigative nature,
and whether formal or informal in any case, in which Indemnitee was, is or will be involved as a party, potential party, non-party witness, or otherwise by reason of: (i) the fact that Indemnitee is or
was a director or officer of the Company; (ii) the fact that any action taken by Indemnitee (or a failure to take action by Indemnitee) or of any action (or failure to act) on Indemnitee’s part while acting as an Agent; or (iii) the
fact that Indemnitee is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan, or other enterprise, and in any such case described
above, whether or not serving in any such capacity at the time any liability or Expense is incurred for which indemnification, reimbursement, or advancement of Expenses may be provided under this Agreement. If the Indemnitee believes in good faith
that a given situation may lead to or culminate in the institution of a proceeding, this shall be considered a proceeding under this paragraph. 

(g) Subsidiary. For purposes of this Agreement, the term “subsidiary” means any corporation, limited liability
company, or other entity, of which more than 50% of the outstanding voting securities or equity interests are owned, directly or indirectly, by the Company and one or more of its subsidiaries, and any other corporation, limited liability company,
partnership, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as an Agent. 

(h) Voting Securities. For purposes of this Agreement, “Voting Securities” shall mean any securities of the
Company that vote generally in the election of directors. 
 2. Agreement to Serve. Indemnitee will serve, or continue to serve, as
the case may be, as an Agent, faithfully and to the best of his or her ability, at the will of such entity designated by the Company and at the request of the Company (or under separate agreement, if such agreement exists), in the capacity
Indemnitee currently serves such entity, so long as Indemnitee is duly appointed or elected and qualified in accordance with the applicable provisions of the governance documents of such entity, or until such time as Indemnitee tenders his or her
resignation in writing; provided, however, that nothing contained in this Agreement is intended as an employment agreement between Indemnitee and the Company or any of its subsidiaries or to create any right to continued employment of Indemnitee
with the Company or any of its subsidiaries in any capacity. 
 The Company acknowledges that it has entered into this Agreement and assumes
the obligations imposed on it hereby, in addition to and separate from its obligations to Indemnitee under the Bylaws, to induce Indemnitee to serve, or continue to serve, as an Agent, and the Company acknowledges that Indemnitee is relying upon
this Agreement in serving as an Agent.

 3. Indemnification. 

(a) Indemnification in Third Party Proceedings. Subject to Section 10 below, the Company shall indemnify Indemnitee to the fullest
extent permitted by the Code, as the same may be amended from time to time (but, to the fullest extent of the law, only to the extent that such amendment permits Indemnitee broader indemnification rights than the Code permitted prior to adoption of
such amendment), if Indemnitee is a party to or threatened to be made a party to or otherwise involved in any proceeding, other than a proceeding by or in the right of the Company to procure a judgment in its favor, for any and all Expenses and
Liabilities (including all interest, assessments and other charges paid or payable in connection with or in respect of such Expenses and Liabilities) incurred by Indemnitee in connection with the investigation, defense, settlement or appeal of such
proceeding, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company and, in the case of a criminal proceeding had no reasonable cause to believe that
Indemnitee’s conduct was unlawful. The parties hereto intend that this Agreement shall provide to the fullest extent permitted by law for indemnification in excess of that expressly permitted by statute, including, without limitation, any
indemnification provided by the Certificate of Incorporation of the Company, the Bylaws, vote of its stockholders or disinterested directors, or applicable law. 

(b) Indemnification in Derivative Actions and Direct Actions by the Company. Subject to Section 10 below, the Company shall
indemnify Indemnitee to the fullest extent permitted by the Code, as the same may be amended from time to time (but, fullest extent permitted by applicable law, only to the extent that such amendment permits Indemnitee broader indemnification rights
than the Code permitted prior to adoption of such amendment), if Indemnitee is a party to or threatened to be made a party to or otherwise involved in any proceeding by or in the right of the Company to procure a judgment in its favor, against any
and all Expenses actually and reasonably incurred by Indemnitee in connection with the investigation, defense, settlement, or appeal of such proceedings, if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or
not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 3(b) in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged by a court competent
jurisdiction to be liable to the Company, unless and only to the extent that the Chancery Court of the State of Delaware or any court in which the proceeding was brought shall determine upon application that, despite the adjudication of liability
but in view of all the circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification. 
 4. Indemnification
of Expenses of Successful Party. Notwithstanding any other provision of this Agreement, in circumstances where indemnification is not available under Section 3(a) or 3(b), as the case may be, to the fullest extent permitted by law and to
the extent that Indemnitee is a party to (or a participant in) any proceeding and has been successful on the merits or otherwise in defense of any proceeding or in defense of any claim, issue or matter therein, in whole or part, including the
dismissal of any action without prejudice, the Company shall indemnify Indemnitee against all Expenses and Liabilities in connection with the investigation, defense or appeal of such proceeding. If Indemnitee is not wholly successful in such
proceeding but is successful, on the merits or otherwise, as to one or more but less than all claims, issues or matters in such proceeding, the Company shall indemnify Indemnitee against all Expenses and Liabilities incurred by Indemnitee or on
Indemnitee’s behalf in connection with or related to each successfully resolved claim, issue or matter to the fullest extent permitted by law. 

5. Partial Indemnification; Witness Indemnification. If Indemnitee is entitled under any provision of this Agreement to indemnification
by the Company for some or a portion of any Expenses and Liabilities incurred by Indemnitee in the investigation, defense, settlement or appeal of a proceeding, but is precluded by applicable law or the specific terms of this Agreement to
indemnification for the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion thereof to which Indemnitee is entitled. Notwithstanding any other provision of this Agreement, to the fullest extent permitted by
applicable law and to the extent that Indemnitee is, by reason of Indemnitee’s acting as an Agent, a witness or otherwise asked to participate in any proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified against all
Expenses incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 

  
 4 

 6. Advancement of Expenses. To the extent not prohibited by law, the Company shall advance
the Expenses incurred by Indemnitee in connection with any proceeding, and such advancement shall be made within twenty (20) days after the receipt by the Company of a statement or statements requesting such advances (which shall include
invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal work performed or to expenditures made that would cause Indemnitee to waive any privilege
accorded by applicable law shall not be included with the invoice) and upon request of the Company, an undertaking to repay the advancement of Expenses if and to the extent that it is ultimately determined by a court of competent jurisdiction in a
final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by the Company. Advances shall be unsecured, interest free and without regard to Indemnitee’s ability to repay the Expenses. Advances shall include any and
all Expenses incurred by Indemnitee pursuing an action to enforce Indemnitee’s right to indemnification under this Agreement or otherwise and this right of advancement, including expenses incurred preparing and forwarding statements to the
Company to support the advances claimed. Indemnitee acknowledges that the execution and delivery of this Agreement shall constitute an undertaking providing that Indemnitee shall, to the fullest extent required by law, repay the advance (without
interest) if and to the extent that it is ultimately determined by a court of competent jurisdiction in a final judgment, not subject to appeal, that Indemnitee is not entitled to be indemnified by the Company. The right to advances under this
Section shall continue until final disposition of any proceeding, including any appeal therein. This Section 6 shall not apply to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 10(b). 

7. Notice and Other Indemnification Procedures. 

(a) Notification of Proceeding. Indemnitee will notify the Company in writing promptly upon being served with any summons, citation,
subpoena, complaint, indictment, information or other document relating to any proceeding or matter which may be subject to indemnification or advancement of Expenses covered hereunder. The written notification to the Company shall include a
description of the nature of the proceeding and the facts underlying the proceeding. The failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to Indemnitee under this Agreement or otherwise
and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights under this Agreement. 
 (b) Request
for Indemnification Payments. To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee
and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification under the terms of this Agreement, and shall request payment thereof by the Company. 

  
 5 

 (c) Determination of Right to Indemnification Payments. Upon written request by Indemnitee
for indemnification pursuant to the Section 7(b) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board
of Directors: (1) by a majority vote of the disinterested directors, even though less than a quorum; (2) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though less than a
quorum; (3) if there are no disinterested directors or if the disinterested directors so direct, by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the Indemnitee; or (4) if so
directed by the Board of Directors, by the stockholders of the Company; provided, however, that if there has been a Change in Control, then such determination shall be made by Independent Counsel selected by Indemnitee and approved by the
Company (which approval shall not be unreasonably withheld). For purposes hereof, disinterested directors are those members of the board of directors of the Company who are not parties to the action, suit or proceeding in respect of which
indemnification is sought by Indemnitee. Indemnification payments requested by Indemnitee under Section 3 hereof shall be made by the Company no later than sixty (60) days after receipt of the written request of Indemnitee. Claims for
advancement of Expenses shall be made under the provisions of Section 6 herein. 
 (d) Application for Enforcement. In the event
the Company fails to make timely payments as set forth in Sections 6 or 7(b) above, Indemnitee shall have the right to apply to any court of competent jurisdiction for the purpose of enforcing Indemnitee’s right to indemnification or
advancement of Expenses pursuant to this Agreement. In such an enforcement hearing or proceeding, the burden of proof shall be on the Company to prove that indemnification or advancement of Expenses to Indemnitee is not required under this Agreement
or permitted by applicable law. Any determination by the Company (including its Board of Directors, a committee thereof, Independent Counsel) or stockholders of the Company, that Indemnitee is not entitled to indemnification hereunder, shall not be
a defense by the Company to the action nor create any presumption that Indemnitee is not entitled to indemnification or advancement of Expenses hereunder. 

(e) Indemnification of Certain Expenses. The Company shall indemnify Indemnitee against all Expenses incurred in connection with any
hearing or proceeding under this Section 7 unless the Company prevails in such hearing or proceeding on the merits in all material respects. 

8. Assumption of Defense. In the event the Company shall be requested by Indemnitee to pay the Expenses of any proceeding, the Company,
if appropriate, shall be entitled to assume the defense of such proceeding, or to participate to the extent permissible in such proceeding, with counsel reasonably acceptable to Indemnitee. Upon assumption of the defense by the Company and the
retention of such counsel by the Company, the Company shall not be liable to Indemnitee under this Agreement for any fees of counsel subsequently incurred by Indemnitee with respect to the same proceeding, provided that Indemnitee shall have the
right to employ separate counsel in such proceeding at Indemnitee’s sole cost and expense. Notwithstanding the foregoing, if Indemnitee’s counsel delivers a written notice to the Company stating that such counsel has reasonably concluded
that there may be a conflict of interest between the Company and Indemnitee in the conduct of any such defense or the Company shall not, in fact, have employed counsel or otherwise actively pursued the defense of such proceeding within a reasonable
time, then in any such event the fees and Expenses of Indemnitee’s counsel to defend such proceeding shall be subject to the indemnification and advancement of Expenses provisions of this Agreement. 

9. Insurance. To the extent that the Company maintains an insurance policy or policies providing liability insurance for Agents
(“D&O Insurance”), Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the maximum extent of the coverage available for any such Agent under such policy or policies. If, at the
time of the receipt of a notice of a claim pursuant to the terms hereof, the Company has D&O Insurance in effect or otherwise potentially available, the Company shall give prompt notice of the commencement of such proceeding to the insurers in
accordance with the procedures set forth in the respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies. 

  
 6 

 In the event of a change of control of the Company or the Company dissolving or liquidating
(including being placed into receivership or entering the federal bankruptcy process and the like), the Company shall maintain in force any and all insurance policies then maintained by the Company in providing insurance in respect of Indemnitee
(directors’ and officers’ liability, fiduciary, employment practices or otherwise) for a period of at least six years thereafter (a “Tail Policy”). If such coverage is not placed with the incumbent insurance
carriers using the policies that were in place at the time of the change of control or insolvency event, the Tail Policy shall be substantially comparable in scope and amount as the expiring policies, and the insurance carriers for the Tail Policy
shall have an AM Best rating that is the same or better than the AM Best ratings of the expiring policies. 
 10. Exceptions. 

(a) Certain Matters. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement to indemnify Indemnitee on account of any proceeding with respect to: (i) remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such remuneration was in violation of law (and, in
this respect, both the Company and Indemnitee have been advised that the Securities and Exchange Commission believes that indemnification for liabilities arising under the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication, as indicated in Section 10(d) below); (ii) a final judgment rendered against Indemnitee for an accounting, disgorgement or
repayment of profits made from the purchase or sale by Indemnitee of securities of the Company against Indemnitee or in connection with a settlement by or on behalf of Indemnitee to the extent it is acknowledged by Indemnitee and the Company that
such amount paid in settlement resulted from Indemnitee’s conduct from which Indemnitee received monetary personal profit, pursuant to the provisions of Section 16(b) of the Exchange Act or other provisions of any federal, state or local
statute or rules and regulations thereunder; (iii) a final judgment or other final adjudication that Indemnitee’s conduct was in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct (but only to the
extent of such specific determination); or (iv) on account of conduct that is established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which
Indemnitee is not legally entitled. For purposes of the foregoing sentence, a final judgment or other adjudication may be reached in either the underlying proceeding or action in connection with which indemnification is sought or a separate
proceeding or action to establish rights and liabilities under this Agreement. 
 (b) Claims Initiated by Indemnitee. Any provision
herein to the contrary notwithstanding, the Company shall not be obligated to indemnify or advance Expenses to Indemnitee with respect to proceedings or claims initiated or brought by Indemnitee against the Company or its Agents and not by way of
defense, except (i) with respect to proceedings brought to establish or enforce a right to indemnification or advancement under this Agreement or under any other agreement, provision in the Bylaws or the Certificate of Incorporation or
applicable law, or (ii) with respect to any other proceeding initiated by Indemnitee that is either approved by the Board of Directors or Indemnitee’s participation is required by applicable law. However, indemnification or advancement of
Expenses may be provided by the Company in specific cases if the Board of Directors determines it to be appropriate. 

  
 7 

 (c) Unauthorized Settlements. Any provision herein to the contrary notwithstanding, the
Company shall not be obligated pursuant to the terms of this Agreement to indemnify Indemnitee under this Agreement for any amounts paid in settlement of a proceeding effected without the Company’s written consent. Neither the Company nor
Indemnitee shall unreasonably withhold consent to any proposed settlement; provided, however, that the Company may in any event decline to consent to (or to otherwise admit or agree to any liability for indemnification hereunder in respect of) any
proposed settlement if the Company is also a party in such proceeding and determines in good faith that such settlement is not in the best interests of the Company and its stockholders. 

(d) Securities Act Liabilities. Any provision herein to the contrary notwithstanding, the Company shall not be obligated pursuant to
the terms of this Agreement to indemnify Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act of 1933, as amended (the “Securities
Act”), or in any registration statement filed with the SEC under the Securities Act. Indemnitee acknowledges that paragraph (h) of Item 512 of Regulation S-K currently generally requires
the Company to undertake in connection with any registration statement filed under the Securities Act to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Securities
Act on public policy grounds to a court of appropriate jurisdiction and to be governed by any final adjudication of such issue. Indemnitee specifically agrees that any such undertaking shall supersede the provisions of this Agreement and to be bound
by any such undertaking. 
 (e) Prior Payments. Any provision herein to the contrary notwithstanding, the Company shall not be
obligated pursuant to the terms of this Agreement to indemnify or advance Expenses to Indemnitee under this Agreement for which payment has actually been made to or on behalf of Indemnitee under any insurance policy or other indemnity provision,
expect with respect to any excess beyond the amount paid under any insurance policy or indemnity policy. 
 11. Nonexclusivity and
Survival of Rights. The provisions for indemnification and advancement of Expenses set forth in this Agreement shall not be deemed exclusive of any other rights which Indemnitee may at any time be entitled under any provision of applicable law,
the Company’s Certificate of Incorporation, the Bylaws or other agreements, both as to action in Indemnitee’s official capacity and Indemnitee’s action as an Agent, in any court in which a proceeding is brought, and Indemnitee’s
rights hereunder shall continue after Indemnitee has ceased acting as an Agent and shall inure to the benefit of the heirs, executors, administrators and assigns of Indemnitee. The obligations and duties of the Company to Indemnitee under this
Agreement shall be binding on the Company and its successors and assigns until terminated in accordance with its terms. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business or assets of the Company, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this
Agreement in respect of any action taken or omitted by such Indemnitee in his or her corporate status prior to such amendment, alteration or repeal. To the extent that a change in the Code, whether by statute or judicial decision, permits greater
indemnification or advancement of Expenses than would be afforded currently under the Company’s Certificate of Incorporation, the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement
the greater benefits so afforded by such change. No right or remedy herein conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given
hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, by Indemnitee shall not prevent the concurrent assertion or employment of any other right or remedy
by Indemnitee. 

  
 8 

 12. Term. This Agreement shall continue until and terminate upon the later of:
(a) five (5) years after the date that Indemnitee shall have ceased to serve as an Agent; or (b) one (1) year after the final termination of any proceeding, including any appeal then pending, in respect to which Indemnitee was
granted rights of indemnification or advancement of Expenses hereunder. No legal action shall be brought and no cause of action shall be asserted by or in the right of the Company against an Indemnitee or an Indemnitee’s estate, spouse, heirs,
executors or personal or legal representatives after the expiration of five (5) years from the date of accrual of such cause of action, and any claim or cause of action of the Company shall be extinguished and deemed released unless asserted by
the timely filing of a legal action within such five-year period; provided, however, that if any shorter period of limitations is otherwise applicable to such cause of action, such shorter period shall
govern. 
 13. Subrogation. In the event of payment under this Agreement, the Company shall be subrogated to the extent of such
payment to all of the rights of recovery of Indemnitee, who, at the request and expense of the Company, shall execute all papers required and shall do everything that may be reasonably necessary to secure such rights, including the execution of such
documents necessary to enable the Company effectively to bring suit to enforce such rights. 
 14. Interpretation of Agreement. It is
understood that the parties hereto intend this Agreement to be interpreted and enforced so as to provide indemnification and advancement of Expenses to Indemnitee to the fullest extent now or hereafter permitted by law. 

15. Severability. If any provision of this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever,
(a) the validity, legality and enforceability of the remaining provisions of the Agreement (including without limitation, all portions of any paragraphs of this Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Agreement (including, without limitation, all
portions of any paragraph of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by
the provision held invalid, illegal or unenforceable and to give effect to Section 14 hereof. 
 16. Amendment and Waiver. No
supplement, modification, amendment, or cancellation of this Agreement shall be binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other
provision hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 
 17. Notice. Except as otherwise
provided herein, any notice or demand which, by the provisions hereof, is required or which may be given to or served upon the parties hereto shall be in writing and, if by electronic transmission, shall be deemed to have been validly served, given
or delivered when sent, if by overnight delivery, courier or personal delivery, shall be deemed to have been validly served, given or delivered upon actual delivery and, if mailed, shall be deemed to have been validly served, given or delivered
three (3) business days after deposit in the United States mail, as registered or certified mail, with proper postage prepaid and addressed to the party or parties to be notified at the addresses set forth on the signature page of this
Agreement (or such other address(es) as a party may designate for itself by like notice). If to the Company, notices and demands shall be delivered to the attention of the Secretary of the Company. 

  
 9 

 18. Governing Law. This Agreement shall be governed exclusively by and construed according
to the laws of the State of Delaware, as applied to contracts between Delaware residents entered into and to be performed entirely within Delaware. 

19. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute but one and the same Agreement. Only one such counterpart need be produced to evidence the existence of this Agreement. 

20. Headings. The headings of the sections of this Agreement are inserted for convenience only and shall not be deemed to constitute
part of this Agreement or to affect the construction hereof. 
 21. Entire Agreement. Subject to Section 11 hereof, this
Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements, understandings and negotiations, written and oral, between the parties with respect to the subject matter
of this Agreement; provided, however, that this Agreement is a supplement to and in furtherance of the Company’s Certificate of Incorporation, the Bylaws, the Code and any other applicable law, and shall not be deemed a substitute
therefor, and does not diminish or abrogate any rights of Indemnitee thereunder. 
 22. Contribution. To the fullest extent
permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee,
whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and

Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding against such party with the same legal force and validity as if served upon such party personally within the State of Delaware,
(iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court, and (v) waive, and agree not to plead or to make, any claim that any such action or proceeding brought in the Delaware Court has been

	1.	Purposes of the Plan. 

 The purposes of this Plan are to attract and retain personnel for positions with
the Company, to provide additional incentive to Employees, Directors, and Consultants (collectively, “Service Providers”), and to promote the success of the Company’s business. 

The Plan permits the grant of Incentive Stock Options to Employees and the grant of Nonstatutory Stock Options, Stock Appreciation Rights, Restricted Stock,
Restricted Stock Units, Performance Shares, Performance Stock Units, and Performance Awards to any Service Provider. 
  

	2.	Shares Subject to the Plan. 

 (a) Allocation of Shares to Plan. The maximum
aggregate number of Shares that may be issued under the Plan is: 
 (i) 4,700,000 Shares, plus 

(ii) a number of Shares equal to the number of shares of common stock of the Company subject to outstanding awards granted under the Genprex,
Inc. 2009 Stock Plan that, after the Registration Date, expire or otherwise terminate without having been exercised in full and a number of Shares equal to the number of Shares of common stock of the Company issued under awards granted under the
Genprex, Inc. 2009 Stock Plan that, after the Registration Date, are forfeited to the Company, tendered to or withheld by the Company for payment of an exercise price or for tax withholding, or repurchased by the Company due to failure to vest, with
the maximum number of Shares that may be added to the Plan under this Section 2(a)(i) being equal to 2,628,760 Shares, plus 
 (iii) any
additional Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). The Shares may be authorized but unissued Common Stock or Common Stock issued and then reacquired by the Company. 

(b) Automatic Share Reserve Increase. The number of Shares available for issuance under the Plan will be increased on the first day of
each Fiscal Year beginning with the 2018 Fiscal Year, in an amount equal to the lesser of: 
 (i) 5% of the total number of shares of all
classes of the Company’s common stock outstanding on the last day of the immediately preceding Fiscal Year, and 
 (ii) a lower number
of Shares determined by the Administrator. 
 (c) Lapsed Awards. 

(i) Options and Stock Appreciation Rights. If an Option or Stock Appreciation Right expires or becomes unexercisable without having been
exercised in full or is surrendered under an Exchange Program, the unissued Shares subject to the Option or Stock Appreciation Right will become available for future issuance under the Plan. 

  
 - 2 - 

 (ii) Stock Appreciation Rights. Only Shares actually issued pursuant to a Stock
Appreciation Right (i.e., the net Shares issued) will cease to be available under the Plan; all remaining Shares originally subject to the Stock Appreciation Right will remain available for future issuance under the Plan. 

(iii) Full-Value Awards. Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares, Performance
Stock Units or stock-settled Performance Awards that are reacquired by the Company due to failure to vest or are forfeited to the Company will become available for future issuance under the Plan. 

(iv) Withheld Shares. Shares used to pay the Exercise Price of an Award or to satisfy tax withholding obligations related to an Award
will become available for future issuance under the Plan. 
 (v) Cash-Settled Awards. If any portion of an Award under the Plan is
paid to a Participant in cash rather than Shares, that cash payment will not reduce the number of Shares available for issuance under the Plan. 

(d) Incentive Stock Options. The maximum number of Shares that may be issued upon the exercise of Incentive Stock Options will equal
200% of the aggregate Share number stated in Section 2(a) plus, to the extent allowable under Code Section 422, any Shares that become available for issuance under the Plan under Sections 2(b) and 2(c). 

(e) Adjustment. The numbers provided in Sections 2(a), 2(b), and 2(d) will be adjusted as a result of changes in capitalization referred
to in Section 13. 
 (f) Substitute Awards. If the Committee grants Awards in substitution for equity compensation awards
outstanding under a plan maintained by an entity acquired by or consolidated with the Company, the grant of those substitute Awards will not decrease the number of Shares available for issuance under the Plan. 

 

	3.	Administration of the Plan. 

 (a) Procedure. 

(i) General. The Plan will be administered by the Board or a Committee (the “Administrator”). Different Administrators may
administer the Plan with respect to different groups of Service Providers. The Board may retain the authority to concurrently administer the Plan with a Committee and may revoke the delegation of some or all authority previously delegated. 

(ii) Further Delegation. To the extent permitted by Applicable Laws, the Board or a Committee may delegate to 1 or more Officers the
authority to grant Awards to Employees of the Company or any of its Subsidiaries who are not Officers, provided that the delegation must specify any limitations on the authority required by Applicable Laws, including the total number of Shares that
may be subject to the Awards granted by such Officer(s). Such delegation may be revoked at any time by the Board or Committee. Any such Awards will be granted on the form of Award Agreement most recently approved for use by the Board or a Committee
made up solely of Directors, unless the resolutions delegating the authority permit the Officer(s) to use a different form of Award Agreement approved by the Board or a Committee made up solely of Directors. 

  
 - 3 - 

 (iii) Section 162(m). When necessary or desirable for an Award to
qualify as “performance-based compensation” under Section 162(m) of the Code, the Committee shall include at least two persons who are “outside directors” (as defined under Section 162(m) of the Code) and at least two
(or a majority if more than two then serve on the Committee) such “outside directors” shall approve the grant of such Award and determine (as applicable) the Performance Period and any Performance Factors upon which vesting or settlement
of any portion of such Award is to be subject no later than the earlier of (a) the date 90 days after the commencement of the applicable Performance Period, and (b) the date on which 25% of the Performance Period has elapsed, and in any
event at a time when the achievement of the applicable Performance Factors remains substantially uncertain. When required by Section 162(m) of the Code, prior to settlement of any such Award at least two (or a majority if more than two then
serve on the Committee) such “outside directors” then serving on the Committee shall determine and certify in writing the extent to which such Performance Factors have been timely achieved and the extent to which the Shares subject to such
Award have thereby been earned. Awards granted to Participants who are subject to Section 16 of the Exchange Act must be approved by two or more “non-employee directors” (as defined in the
regulations promulgated under Section 16 of the Exchange Act). With respect to Participants whose compensation is subject to Section 162(m) of the Code, and provided that such adjustments are consistent with the regulations promulgated
under Section 162(m) of the Code, the Committee may adjust the performance goals to account for changes in law and accounting and to make such adjustments as the Committee deems necessary or appropriate to reflect the impact of extraordinary or
unusual items, events or circumstances to avoid windfalls or hardships, including without limitation (i) restructurings, discontinued operations, extraordinary items, and other unusual or non-recurring
charges, (ii) an event either not directly related to the operations of the Company or not within the reasonable control of the Company’s management, or (iii) a change in accounting standards required by generally accepted accounting
principles. No Participant will be eligible to receive more than 1,175,000 (25% of Share Reserve Shares) in any calendar year under this Plan pursuant to the grant of Awards except that new Employees of the Company or a member of the Company Group
(including new Employees who are also officers and directors of the Company or a member of the Company Group) are eligible to receive up to a maximum of 2,350,000 (50% of Share Reserve Shares) in the calendar year in which they commence their
employment, and no Participant shall be granted a cash settled award with a value greater than $2,000,000. 
 (b) Powers of the
Administrator. Subject to the terms of the Plan, any limitations on delegations specified by the Board, and any requirements imposed by Applicable Laws, the Administrator will have the authority, in its sole discretion, to make any
determinations and perform any actions deemed necessary or advisable to administer the Plan including: 
 (i) to determine the Fair Market
Value; 

  
 - 4 - 

 (ii) to approve forms of Award Agreements for use under the Plan (provided that all forms of
Award Agreement must be approved by the Board or the Committee of Directors acting as the Administrator); 
 (iii) to select the Service
Providers to whom Awards may be granted and grant Awards to such Service Providers; 
 (iv) to determine the number of Shares to be covered
by each Award granted; 
 (v) to determine the terms and conditions, consistent with the Plan, of any Award granted. Such terms and
conditions may include, but are not limited to, the Exercise Price, the time(s) when Awards may be exercised (which may be based on performance criteria), any vesting acceleration or waiver of forfeiture restrictions, and any restriction or
limitation regarding any Award or the Shares relating to an Award; 
 (vi) to institute and determine the terms and conditions of an Exchange
Program; 
 (vii) to interpret the Plan and make any decisions necessary to administer the Plan; 

(viii) to establish, amend and rescind rules relating to the Plan, including rules relating to
sub-plans established to satisfy laws of jurisdictions other than the United States or to qualify Awards for favorable tax treatment under laws of jurisdictions other than the United States; 

(ix) to interpret, modify or amend each Award (subject to Section 18), including extending the Expiration Date and the post-termination
exercisability period of such modified or amended Awards; 
 (x) to allow Participants to satisfy tax withholding obligations in any manner
permitted by Section 15; 
 (xi) to delegate ministerial duties to any of the Company’s employees; 

(xii) to authorize any person to take any steps and execute, on behalf of the Company, any documents required for an Award previously granted
by the Administrator to be effective; and 
 (xiii) to allow Participants to defer the receipt of the payment of cash or the delivery of
Shares otherwise due to any such Participants under an Award. 
 (c) Termination of Status. 

(i) Unless a Participant is on a leave of absence approved by the Company as set forth in Section 11, the Participant’s status as a
Service Provider will end at midnight at the end of the last day the Participant actively provides services for a member of the Company Group (the “Termination of Status Date”). The Administrator has the sole discretion to determine

  
 - 5 - 

 
the date on which a Participant stops actively providing services and whether a Participant may still be considered to be providing services while on a leave of absence and the Administrator may
delegate this decision, other than with respect to Officers, to the Company’s senior human resources officer. 
 (ii) This termination
of status as a Service Provider will occur regardless of the reason for such termination even if the termination is later found to be invalid, in breach of employment laws in the jurisdiction where Participant is providing services, or in violation
of the terms of Participant’s employment or service agreement, if any such agreement exists. 
 (iii) Unless otherwise expressly
provided in an Award Agreement or otherwise determined by the Administrator, a Participant’s right to vest in any Award under the Plan will cease as of the Termination of Status Date and will not be extended by any notice period, whether
arising under contract, statute or common law, including any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where the Participant is providing services. 

(d) Grant Date. The grant date of an Award (“Grant Date”) will be the date that the Administrator makes the determination
granting such Award or may be a later date if such later date is designated by the Administrator on the date of the determination or under an automatic grant policy. Notice of the determination will be provided to each Participant within a
reasonable time after the Grant Date. 
 (e) Waiver. The Administrator may waive any terms, conditions or restrictions. 

(f) Fractional Shares. Except as otherwise provided by the Administrator, any fractional Shares that result from the adjustment of
Awards will be canceled. Any fractional Shares that result from vesting percentages will be accumulated and vested on the date that an accumulated full Share is vested. 

(g) Electronic Delivery. The Company may deliver by e-mail or other electronic means (including
posting on a website maintained by the Company or by a third party under contract with the Company or another member of the Company Group) all documents relating to the Plan or any Award and all other documents that the Company is required to
deliver to its security holders (including prospectuses, annual reports and proxy statements). 
 (h) Choice of Law; Choice of Forum.
The Plan, all Awards and all determinations made and actions taken under the Plan, to the extent not otherwise governed by the laws of the United States, will be governed by the laws of the State of Delaware without giving effect to principles of
conflicts of law. For purposes of litigating any dispute that arises under this Plan, a Participant’s acceptance of an Award is his or her consent to the jurisdiction of the State of Delaware, and agreement that any such litigation will be
conducted in Delaware Court of Chancery, or the federal courts for the United States for the District of Delaware, and no other courts, regardless of where a Participant’s services are performed. 

(i) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations will be final and
binding on all Participants and any other holders of Awards. 

  
 - 6 - 

	4.	Stock Options. 

 (a) Stock Option Award Agreement. Each Option will be evidenced
by an Award Agreement that will specify the number of Shares subject to the Option, its per share exercise price (“Exercise Price”), its Expiration Date, and such other terms and conditions as the Administrator determines. Each Option will
be designated in the Award Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. An Option not designated as an Incentive Stock Option is a Nonstatutory Stock Option. 

(b) Exercise Price. The Exercise Price for the Shares to be issued upon exercise of an Option will be determined by the Administrator.

 (c) Form of Consideration. The Administrator will determine the acceptable forms of consideration for exercising an Option and
those forms of consideration will be described in the Award Agreement. The consideration may consist of any combination of the following, to the extent permitted by Applicable Laws: 

(i) cash; 
 (ii) check or wire
transfer; 
 (iii) promissory note; 

(iv) other Shares that have a fair market value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such
Option will be exercised. To the extent not prohibited by the Administrator, this shall include the ability to tender Shares to exercise the Option and then use the Shares received on exercise to exercise the Option with respect to additional
Shares; 
 (v) consideration received by the Company under a cashless exercise arrangement (whether through a broker or otherwise)
implemented by the Company for the exercise of Options that has been approved by the Board or a Committee of Directors; 
 (vi) consideration
received by the Company under a net exercise program under which Shares are withheld from otherwise deliverable Shares that has been approved by the Board or a Committee of Directors; and 

(vii) any other consideration or method of payment to issue Shares (provided that other forms of considerations may only be approved by the
Board or a Committee of Directors). 
 (d) Incentive Stock Option Limitations. 

(i) The Exercise Price of an Incentive Stock Option may not be less than 100% of the Fair Market Value on the Grant Date. 

  
 - 7 - 

 (ii) To the extent that the aggregate fair market value of the shares with respect to which
incentive stock options under Code Section 422(b) are exercisable for the first time by a Participant during any calendar year (under all plans and agreements of the Company Group) exceeds $100,000, the incentive stock options whose value
exceeds $100,000 will be treated as nonstatutory stock options. Incentive stock options will be considered in the order in which they were granted. For this purpose the fair market value of the shares subject to an option will be determined as of
the grant date of each option. 
 (iii) The Expiration Date of an Incentive Stock Option will be the day prior to the 10th anniversary of the
Grant Date or any earlier date provided in the Award Agreement, subject to clause (iv) below. 
 (iv) The following rules apply to
Incentive Stock Options granted to Participants who own stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary of the Company: 

(1) the Expiration Date of the Incentive Stock Option may not be after the day prior to the 5th anniversary of the Grant Date; and 

(2) the Exercise Price may not be less than 110% of the Fair Market Value on the Grant Date. 

If an Option is designated in the Administrator action that granted it as an Incentive Stock Option but the terms of the Option do not comply with Sections
4(d)(iv)(1) and 4(d)(iv)(2), then the Option will not qualify as an Incentive Stock Option. All Options granted under the Plan are Nonstatutory Stock Options unless specifically designated as Incentive Stock Options in the Award Agreement pursuant
to which such Options are granted. 
 (e) Exercise of Option. An Option is exercised when the Company receives: (i) a notice of
exercise (in such form as the Administrator may specify from time to time) from the person entitled to exercise the Option and (ii) full payment for the Shares with respect to which the Option is exercised (together with applicable withholding
taxes). Shares issued upon exercise of an Option will be issued in the name of the Participant. Until the Shares are issued (as evidenced by the entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to
vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to an Option, despite the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is
exercised. An Option may not be exercised for a fraction of a Share. Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for purchase under the Option, by the number of Shares
as to which the Option is exercised. 
 (f) Expiration of Options. Subject to Section 4(d), an Option’s Expiration Date will
be set forth in the Award Agreement. An Option may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement. 

(g) Tolling of Expiration. If exercising an Option prior to its expiration is not permitted because of Applicable Laws, other than the
rules of any stock exchange or quotation system on which the Common Stock is listed or quoted, the Option will remain exercisable until 30 days after the first date on which exercise would no longer be prevented by such provisions. If this would
result in the Option remaining exercisable past its Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would not be prevented by Section 19(a) and (y) its
Expiration Date. 

  
 - 8 - 

	5.	Restricted Stock. 

 (a) Restricted Stock Award Agreement. Each Award of Restricted
Stock will be evidenced by an Award Agreement that will specify the Period of Restriction (if any), the number of Shares granted, and such other terms and conditions as the Administrator determines. Unless the Administrator determines otherwise,
Shares of Restricted Stock will be held in escrow until the end of the Period of Restriction applicable to such Shares. All grants of Restricted Stock and interpretative decisions about Restricted Stock may only be made by the Administrator. 

(b) Restrictions: 
 (i)
Except as provided in this Section 5 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated until the end of the Period of Restriction applicable to such Shares. 

(ii) During the Period of Restriction, Service Providers holding Shares of Restricted Stock may exercise full voting rights with respect to
those Shares, unless the Administrator determines otherwise. 
 (iii) During the Period of Restriction, Service Providers holding Shares of
Restricted Stock will not be entitled to receive dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If the Administrator provides that dividends and distributions will be received and any
such dividends or distributions are paid in cash they will be subject to the same provisions regarding forfeitability as the Shares of Restricted Stock with respect to which they were paid and if such dividend or distributions are paid in Shares,
the Shares will be subject to the same restrictions on transferability and forfeitability as the Shares of Restricted Stock with respect to which they were paid and, unless the Administrator determines otherwise, the Company will hold such Shares
until the restrictions on the Shares of Restricted Stock with respect to which they were paid have lapsed. 
 (iv) Except as otherwise
provided in this Section 5 or an Award Agreement, Shares of Restricted Stock covered by each Restricted Stock Award made under the Plan will be released from escrow when practicable after the last day of the applicable Period of Restriction.

 (v) The Administrator may impose, prior to grant, or remove any restrictions on Shares of Restricted Stock. 

 

	6.	Restricted Stock Units. 

 (a) Restricted Stock Unit Award Agreement. Each Award of
Restricted Stock Units will be evidenced by an Award Agreement that will specify the terms, conditions, and restrictions related to the grant, including the number of Restricted Stock Units. 

  
 - 9 - 

 (b) Vesting Criteria and Other Terms. The Administrator will set vesting criteria that,
depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of Company-wide, divisional, business unit,
or individual goals (that may include continued employment or service) or any other basis determined by the Administrator in its sole discretion. 

(c) Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will have earned the Restricted Stock
Units and will be paid as determined in Section 6(d). The Administrator may reduce or waive any criteria that must be met to earn the Restricted Stock Units. 

(d) Form and Timing of Payment. Payment of earned Restricted Stock Units will be made when practicable after the date set forth in the
Award Agreement and determined by the Administrator. The Administrator may settle earned Restricted Stock Units in cash, Shares, or a combination of both. 
  

	7.	Stock Appreciation Rights. 

 (a) Stock Appreciation Right Award Agreement. Each
Stock Appreciation Right grant will be evidenced by an Award Agreement that will specify the Exercise Price (which may not be less than 100% of Fair Market Value on the Grant Date), its Expiration Date, the conditions of exercise, and such other
terms and conditions as the Administrator determines. 
 (b) Payment of Stock Appreciation Right Amount. When a Participant exercises
a Stock Appreciation Right, he or she will be entitled to receive a payment from the Company equal to: 
 (i) the difference between the Fair
Market Value on the date of exercise and the Exercise Price multiplied by 
 (ii) the number of Shares with respect to which the Stock
Appreciation Right is exercised. 
 Payment upon Stock Appreciation Right exercise may be made in cash, in Shares of equivalent value, or any combination of
cash and Shares, with the determination of form of payment made by the Administrator. Shares issued upon exercise of a Stock Appreciation Right will be issued in the name of the Participant. Until Shares are issued (as evidenced by the entry on the
books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder will exist with respect to the Shares subject to a Stock Appreciation Right, despite the exercise
of the Stock Appreciation Right. The Company will issue (or cause to be issued) such Shares promptly after the Stock Appreciation Right is exercised. A Stock Appreciation Right may not be exercised for a fraction of a Share. 

Exercising a Stock Appreciation Right in any manner will decrease (x) the number of Shares thereafter available under the Stock Appreciation Right by the
number of Shares as to which the Stock Appreciation Right is exercised and (y) the number of Shares thereafter available under the Plan by the number of Shares issued upon such exercise. 

  
 - 10 - 

 (c) Expiration of Stock Appreciation Rights. A Stock Appreciation Right’s Expiration
Date will be set forth in the Award Agreement. A Stock Appreciation Right may expire before its expiration date under Sections 14 or 16(b) or under the Award Agreement. 

(d) Tolling of Expiration. If exercising an Stock Appreciation Right prior to its expiration is not permitted because of Applicable
Laws, other than the rules of any stock exchange or quotation system on which the Common Stock is listed or quoted, the Stock Appreciation Right will remain exercisable until 30 days after the first date on which exercise would no longer be
prevented by such provisions. If this would result in the Stock Appreciation Right remaining exercisable past its Expiration Date, then it will remain exercisable only until the end of the later of (x) the first day on which its exercise would
not be prevented by Section 19(a) and (y) its Expiration Date. 
  

	8.	Performance Stock Units and Performance Shares. 

 (a) Award Agreement. Each Award
of Performance Stock Units/Shares will be evidenced by an Award Agreement that will specify the time period during which the performance objectives or other vesting provisions will be measured which shall not exceed 5 years (“Performance
Period”) and the material terms of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals (including, but not limited to, continued employment or
service) or any other basis determined by the Administrator. 
 (b) Value of Performance Stock Units/Shares. Each Performance Stock
Unit will have an initial value established by the Administrator on or before the Grant Date. Each Performance Share will have an initial value equal to the Fair Market Value on the Grant Date. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may
include continued employment or service). These objectives or vesting provisions may determine the number or value of Performance Stock Units/Shares paid out. 

(d) Earning of Performance Stock Units/Shares. After an applicable Performance Period has ended, the holder of Performance Stock
Units/Shares will be entitled to receive a payout of the number of Performance Stock Units/Shares earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for
such Performance Stock Unit/Share. 
 (e) Payment of Performance Stock Units/Shares. Payment of earned Performance Stock Units/Shares
will be made when practicable after the end of the applicable Performance Period. Payment with respect to earned Performance Stock Units/Shares may be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the
determination of form of payment made by the Administrator. 

  
 - 11 - 

	9.	Performance Awards. 

 (a) Award Agreement. Each Performance Award will be
evidenced by an Award Agreement that will specify the Performance Period and the material terms of the Award. The Administrator may set performance objectives based upon the achievement of Company-wide, divisional, business unit or individual goals
(including, but not limited to, continued employment or service) or any other basis determined by the Administrator. 
 (b) Value of
Performance Awards. Each Performance Award’s threshold, target, and maximum payout values will be established by the Administrator on or before the Grant Date. 

(c) Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting provisions (that may
include continued employment or service). These objectives or vesting provisions will determine the value of the payout for the Performance Awards. 

(d) Earning of Performance Awards. After an applicable Performance Period has ended, the holder of a Performance Award will be entitled
to receive a payout for the Performance Award earned by the Participant over the Performance Period. The Administrator may reduce or waive any performance objectives or other vesting provisions for such Performance Award. 

(e) Payment of Performance Awards. Payment of earned Performance Awards will be made when practicable after the end of the applicable
Performance Period. Payment with respect to earned Performance Awards will be made in cash, in Shares of equivalent value, or any combination of cash and Shares, with the determination of form of payment made by the Administrator at the time of
payment. 
  

	10.	Outside Director Limitations. 

 No Outside Director may be granted, in any Fiscal Year, Awards with a
grant date fair value (determined under U.S. generally accepted accounting principles) of more than $1,000,000, increased to $2,000,000 in connection with his or her initial service as an Outside Director. Awards granted to an individual while he or
she was an Employee, or while he or she was a Consultant but not an Outside Director, will not count for purpose of this limitation. 
  

	11.	Leaves of Absence/Transfer Between Locations/Change of Status. 

 (a) General.
Unless otherwise provided by the Administrator, a Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or other member of the Company Group employing such Employee or (ii) any
transfer between locations of the Company or members of the Company Group. 
 (b) Vesting. Unless a leave policy approved by the
Administrator provides otherwise or it is otherwise required by Applicable Law, vesting of Awards granted under the Plan will continue only for Participants on an approved leave of absence. 

(c) Incentive Stock Option Status. If a Participant’s leave of absence approved by the Company or other member of the Company Group
employing such Employee exceeds 3 months and reemployment upon expiration of such leave is not guaranteed by statute or contract, then 3 months following the 1st day of such leave the Participant will no longer be an employee for incentive stock
option purposes. If reemployment upon expiration of such leave of absence is not guaranteed by statute or contract, then 6 months following the 1st day of such leave any Incentive Stock Option held by the Participant will cease to be treated as an
Incentive Stock Option and will be treated for tax purposes as a Nonstatutory Stock Option. 

  
 -12- 

 (d) Protected Leaves. 

(i) Any leave of absence by a Participant will be subject to any Applicable Laws that apply to leaves of absence. 

(ii) For a Participant on a military leave, if required by Applicable Laws, vesting will continue for the longest period that vesting continues
under any other statutory or Company-approved leave of absence. When a Participant returns from military leave (under conditions that would entitle him or her to such protection under the Uniformed Services Employment and Reemployment Rights Act),
the Participant will be given vesting credit to the same extent as if the Participant had continued to provide services to the Company or other member of the Company Group, as applicable, through the military leave. 

(e) Changes in Status. If a Participant who is an Employee has a reduction in hours worked, the Administrator may unilaterally: 

(i) make a corresponding reduction in the number of Shares or cash amount subject to any portion of an Award that is scheduled to vest or
become payable after the date of such extend leave or reduction in hours; and 
 (ii) in lieu of or in combination with such a reduction,
extend the vesting or payment schedule applicable to such Award. 
 If any such reduction occurs, the Participant will have no right to any portion of the
Award that is reduced. 
 (f) Determinations. The effect of a Company-approved leave of absence, a transfer, or a Participant’s
reduction in hours of employment or service on the vesting of an Award shall be determined, under policies reviewed by the Administrator, by the Company’s senior human resources officer or other person performing that function or, with respect
to Directors or Officers by the Compensation Committee of the Board, and any such determination will be final. 
  

	12.	Transferability of Awards. 

 (a) General Rule. Unless determined otherwise by the
Administrator, or otherwise required by Applicable Laws, an Award may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during
the lifetime of the Participant, only by the Participant. If the Administrator makes an Award transferable, the Award will be limited by any additional terms and conditions imposed by the Administrator. Any unauthorized transfer of an Award will be
void. 

  
 - 13 - 

 (b) Domestic Relations Orders. If approved by the Administrator, an Award may be
transferred under a domestic relations order, official marital settlement agreement or other divorce or separation instrument as permitted by Treasury Regulations Section 1.421-1(b)(2). An Incentive Stock
Option may be converted into a Nonstatutory Stock Option as a result of such transfer. 
 (c) Limited Transfers for the Benefit of Family
Members. The Administrator may permit an Award or Share issued under this Plan to be assigned or transferred subject to the applicable limitations, set forth in the General Instructions to Form S-8
Registration Statement under the Securities Act, if applicable, and any other Applicable Laws. 
 (d) Permitted Transferees. Any
individual or entity to whom an Award is transferred will be subject to all of the terms and conditions applicable to the Participant who transferred the Award, including the terms and conditions in this Plan and the Award Agreement. If an Award is
unvested then the service of the Participant will continue to determine whether the Award will vest and any Expiration Date. 
  

	13.	Adjustments; Dissolution or Liquidation. 

 (a) Adjustments. If any extraordinary
dividend or other extraordinary distribution (whether in cash, Shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up,
spin-off, combination, repurchase, or exchange of Shares or other securities of the Company, issuance of warrants or other rights to acquire securities of the Company, other change in the corporate structure
of the Company affecting the Shares, or any similar equity restructuring transaction, as that term is used in Statement of Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any of its successors) affecting the
Shares occurs (including, without limitation, a Change in Control), the Administrator, to prevent diminution or enlargement of the benefits or potential benefits intended to be provided under the Plan, will adjust the number and class of shares that
may be delivered under the Plan and/or the number, class, and price of shares covered by each outstanding Award, and the numerical Share limits in Section 2 in such a manner as it deems equitable. Notwithstanding the foregoing, the conversion
of any convertible securities of the Company and ordinary course repurchases of shares or other securities of the Company will not be treated as an event that will require adjustment. 

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator will notify
each Participant when practicable prior to the effective date of such proposed transaction. To the extent it has not been previously exercised, an Award will terminate immediately prior to the consummation of such proposed action. 

 

	14.	Change in Control. 

 (a) Administrator Discretion. If a Change in Control or a
merger of the Company with or into another corporation or other entity occurs, each outstanding Award will be treated as the Administrator determines, including, without limitation, that such Award be continued by the successor corporation or a
Parent or Subsidiary of the successor corporation. 
 (b) Identical Treatment Not Required. The Administrator need not take the same
action or actions with respect to all Awards or portions thereof or with respect to all Participants. 

  
 - 14 - 

 
The Administrator may take different actions with respect to the vested and unvested portions of an Award. The Administrator will not be required to treat all Awards similarly in the transaction.

 (c) Continuation. An Award will be considered continued if, following the Change in Control or merger: 

(i) the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the transaction, the
consideration (whether stock, cash, or other securities or property) received in the transaction by holders of Shares for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of
consideration received by the holders of a majority of the outstanding Shares); provided that if the consideration received in the transaction is not solely common stock of the successor corporation or its Parent, the Administrator may, with the
consent of the successor corporation, provide for the consideration to be received upon exercising an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Stock Unit, Performance Share or Performance Award,
for each Share subject to such Award, to be solely common stock of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Common Stock in the transaction; or 

(ii) the Award is terminated in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon
the exercise of such Award or realization of the Participant’s rights as of the date of the occurrence of the transaction. Any such cash or property may be subjected to any escrow applicable to holders of Common Stock in the Change of Control.
If as of the date of the occurrence of the transaction the Administrator determines that no amount would have been attained upon the exercise of such Award or realization of the Participant’s rights, then such Award may be terminated by the
Company without payment. The amount of cash or property can be subjected to vesting and paid to the Participant over the original vesting schedule of the Award. 

(iii) Notwithstanding anything in this Section 14(c) to the contrary, an Award that vests, is earned or
paid-out upon the satisfaction of one or more performance goals will not be considered assumed if the Company or its successor modifies any of such performance goals without the Participant’s consent;
provided, however, a modification to such performance goals only to reflect the successor corporation’s post-transaction corporate structure will not invalidate an otherwise valid Award assumption. 

(d) The Administrator will have authority to modify Awards in connection with a Change in Control or merger: 

(i) in a manner that causes them to lose their tax-preferred status, 

(ii) to terminate any right a Participant has to exercise an Option prior to vesting in the Shares subject to the Option (i.e., “early
exercise”), so that following the closing of the transaction the Option may only be exercised to the extent it is vested; 
 (iii) to
reduce the Exercise Price subject to the Award in a manner that is disproportionate to the increase in the number of Shares subject to the Award, as long as the amount that would be received upon exercise of the Award immediately before and
immediately following the closing of the transaction is equivalent and the adjustment complies with Treasury Regulation Section 1.409A-1(b)(v)(D); and 

  
 - 15 - 

 (iv) to suspend a Participant’s right to exercise an Option during a limited period of time
preceding and or following the closing of the transaction without Participant consent if such suspension is administratively necessary or advisable to permit the closing of the transaction. 

(e) Non-Continuation. If the successor corporation does not continue for an Award (or some
portion such Award), the Participant will fully vest in (and have the right to exercise) 100% of the then-unvested Shares subject to his or her outstanding Options and Stock Appreciation Rights, all restrictions on 100% of the Participant’s
outstanding Restricted Stock and Restricted Stock Units will lapse, and, regarding 100% of Participant’s outstanding Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of
target levels and all other terms and conditions met. In no event will vesting of an Award accelerate as to more than 100% of the Award. If Options or Stock Appreciation Rights are not continued when a Change in Control or a merger of the Company
with or into another corporation or other entity occurs, the Administrator will notify the Participant in writing or electronically that the Participant’s vested Options or Stock Appreciation Rights (after considering the foregoing vesting
acceleration, if any) will be exercisable for a period of time determined by the Administrator in its sole discretion and all of the Participant’s Options or Stock Appreciation Rights will terminate upon the expiration of such period (whether
vested or unvested). 
 (f) Outside Director Awards. With respect to Awards granted to an Outside Director that are continued, if on
the date of or following such continuation the Participant’s status as a Director or a director of the successor corporation, as applicable, is terminated other than upon a voluntary resignation by the Participant that is not at the request of
the acquirer, then the Participant will fully vest in and have the right to exercise Options and/or Stock Appreciation Rights as to all of the Shares underlying such Award, including those Shares not otherwise vested or exercisable, all restrictions
on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, all performance goals or other vesting criteria will be treated as achieved at 100% of target levels and all other terms and
conditions met. 
  

	15.	Tax Matters. 

 (a) Withholding Requirements. Prior to the delivery of any Shares
or cash under an Award (or exercise thereof) or such earlier time as any tax withholding obligations are due, the Company may deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy any taxes (including
the Participant’s social tax obligations) required to be withheld with respect to such Award (or exercise thereof). 
 (b)
Withholding Arrangements. The Administrator, in its sole discretion and under such procedures as it may specify from time to time, may permit or may require a Participant to satisfy such tax withholding obligations, in whole or in part by
(without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash (including cash from 

  
 - 16 - 

 
the sale of Shares issued to Participant) or Shares having a fair market value equal to the minimum statutory amount required to be withheld or a greater amount if that would not result in
unfavorable financial accounting treatment, (iii) delivering to the Company already-owned Shares having a fair market value equal to the minimum statutory amount required to be withheld, or (iv) requiring the Participant to engage in a
cashless exercise transaction (whether through a broker or otherwise) implemented by the Company in connection with the Plan. The fair market value of the Shares to be withheld or delivered will be determined as of the date the taxes must be
withheld. 
 (c) Compliance With Code Section 409A. Except as otherwise determined by the Administrator, it is
intended that Awards will be designed and operated so that they are either exempt from the application of Code Section 409A or comply with any requirements necessary to avoid the imposition of additional tax under Code
Section 409A(a)(1)(B) so that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Code Section 409A and the Plan and each Award Agreement will be interpreted consistent with
this intent. This Section 15(c) is not a guarantee to any Participant of the consequences of his or her Awards. 
  

	16.	Other Terms. 

 (a) No Effect on Employment or Service. Neither the Plan nor any
Award will confer upon a Participant any right regarding continuing the Participant’s relationship as a Service Provider with the Company or member of the Company Group, nor will they interfere with the Participant’s right, or the
Participant’s employer’s right, to terminate such relationship with or without cause, to the extent permitted by Applicable Laws. 

(b) Forfeiture Events. 

(i) All Awards granted under the Plan will be subject to recoupment under any clawback policy that the Company is required to adopt pursuant to
the listing standards of any national securities exchange or association on which the Company’s securities are listed or as is otherwise required by the Dodd-Frank Wall Street Reform and Consumer Protection Act or other Applicable Laws. In
addition, the Administrator may impose such other clawback, recovery or recoupment provisions in an Award Agreement as the Administrator determines necessary or appropriate, including but not limited to a reacquisition right regarding previously
acquired Shares or other cash or property. Unless this Section 16(b) is specifically mentioned and waived in an Award Agreement or other document, no recovery of compensation under a clawback policy or otherwise will give a Participant the
right to resign for “good reason” or “constructive termination” (or similar term) under any agreement with the Company. 

(ii) The Administrator may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award
will be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. In the event of termination of such
Participant’s status as Service Provider for Cause or any act by a Participant, whether before or after such Participant’s Termination Status Date, that would constitute cause for termination of such Participant’s status as a Service
Provider, all Awards will terminate immediately. 

  
 - 17 - 

 (iii) If the Company is required to prepare an accounting restatement due to the material
noncompliance of the Company, as a result of misconduct, with any financial reporting requirement under securities laws, any Participant who (i) knowingly or through gross negligence engaged in the misconduct or who knowingly or through gross
negligence failed to prevent the misconduct or (ii) is one of the individuals subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, must reimburse the Company the amount of any payment in settlement of an
Award earned or accrued during the 12-month period following the first public issuance or filing with the United States Securities and Exchange Commission (whichever first occurred) of the financial document
embodying such financial reporting requirement. 
  

	17.	Term of Plan. 

 Subject to Section 20, the Plan will become effective upon the business day
immediately prior to the Registration Date. It will continue in effect until terminated under Section 18, but no Incentive Stock Options may be granted after 10 years from the date the Plan is adopted by the Board and Section 2(b) will
operate only until the 10th anniversary of the date the Plan is adopted by the Board. 
  

	18.	Amendment and Termination of the Plan. 

 (a) Amendment and Termination. The Board
or Compensation Committee of the Board may amend, alter, suspend or terminate the Plan. 
 (b) Stockholder Approval. The Company will
obtain stockholder approval of any Plan amendment to the extent necessary or desirable to comply with Applicable Laws. 
 (c) Consent of
Participants Generally Required. Subject to Section 18(d) below, no amendment, alteration, suspension or termination of the Plan or an Award under it will materially impair the rights of any Participant without a signed, written agreement
between the Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it regarding Awards granted under the Plan prior to such termination. 

(d) Exceptions to Consent Requirement. 

(i) A Participant’s rights will not be deemed to have been impaired by any amendment, alteration, suspension or termination if the
Administrator, in its sole discretion, determines that the amendment, alteration, suspension or termination taken as a whole, does not materially impair the Participant’s rights; and 

(ii) Subject to any limitations of Applicable Laws, the Administrator may amend the terms of any one or more Awards without the affected
Participant’s consent even if it does materially impair the Participant’s right if such amendment is done 

  
 - 18 - 

 (1) in a manner permitted under the Plan, 

(2) to maintain the qualified status of the Award as an Incentive Stock Option under Code Section 422, 

(3) to change the terms of an Incentive Stock Option, if such change results in impairment of the Award only because it impairs the qualified
status of the Award as an Incentive Stock Option under Code Section 422, 
 (4) to clarify the manner of exemption from Code
Section 409A or compliance with any requirements necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B), or 

(5) to comply with other Applicable Laws. 
  

	19.	Conditions Upon Issuance of Shares. 

 (a) Legal Compliance. Shares will not be
issued pursuant to the exercise of an Award unless the exercise of such Award and the issuance and delivery of such Shares will comply with Applicable Laws. If required by the Administrator, issuance will be further subject to the approval of
counsel for the Company with respect to such compliance. The inability of the Company to obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any Applicable Laws will relieve the Company of
any liability regarding the failure to issue or sell such Shares as to which such authority, registration, qualification or rule compliance was not obtained and the Administrator reserves the authority, without the consent of a Participant, to
terminate or cancel Awards with or without consideration in such a situation. 
 (b) Investment Representations. As a condition to the
exercise of an Award, the Company may require the person exercising such Award to represent and warrant during any such exercise that the Shares are being purchased only for investment and with no present intention to sell or distribute such Shares
if, in the opinion of counsel for the Company, such a representation is required. 
 (c) Failure to Accept Award. If a Participant has
not accepted an Award or has not taken all administrative and other steps (e.g. setting up an account with a broker designated by the Company) necessary for the Company to issue Shares upon the vesting, exercise, or settlement of the Award prior to
the first date the Shares subject such Award are scheduled to vest, then the Award will be cancelled on such date and the Shares subject to such Award immediately will revert to the Plan for no additional consideration unless otherwise provided by
the Administrator. 
  

	20.	Stockholder Approval. 

 The Plan will be subject to approval by the stockholders of the Company within 12
months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

 Notwithstanding the foregoing, if the determination date for the Fair Market Value occurs on a weekend, holiday or other
non-Trading Day, the Fair Market Value will be the price as determined under subsections (i) or (ii) above on the immediately preceding Trading Day, unless otherwise determined by the Administrator. In
addition, for purposes of determining the fair market value of shares for any reason other than the determination of the Exercise Price of Options or Stock Appreciation Rights, fair market value will be determined by the Administrator in a manner
compliant with Applicable Laws and applied consistently for such purpose. Note that the determination of fair market value for purposes of tax withholding may be made in the Administrator’s sole discretion subject to Applicable Laws and is not

 EXHIBIT A 

TERMS AND CONDITIONS OF STOCK OPTION GRANT 

1. Grant. The Company grants the Participant an Option to purchase Shares of Common Stock as described in the Notice of Grant. If there
is a conflict between the Plan, this Agreement, or any other agreement with the Participant governing this Option, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and (c) any
other agreement between the Company and the Participant governing this Option. 
 If the Notice of Grant designates this Option as an
Incentive Stock Option (“ISO”), this Option is intended to qualify as an ISO under Code Section 422. Even if this Option is designated an ISO, to the extent it first become exercisable as to more than $100,000 in any calendar
year, the portion in excess of $100,000 is not an ISO under Code Section 422(d) and that portion will be a Nonstatutory Stock Option (“NSO”). In addition, if the Participant exercises the Option after 3 months have passed since
he or she ceased to be an employee of the Company or a Parent or Subsidiary of the Company, it will no longer be an ISO. If there is any other reason this Option (or a portion of it) will not qualify as an ISO, to the extent of such
nonqualification, the Option will be an NSO. The Participant understands that he or she will have no recourse against the Administrator, any member of the Company Group, or any officer or director of a member of the Company Group if any portion of
this Option is not an ISO. 
 2. Vesting. This Option will only be exercisable (also referred to as vested) under the Vesting Schedule
in the Notice of Grant, Section 3 of this Agreement, or Section 14 of the Plan. Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to be a Service
Provider until the time such vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

3. Administrator Discretion. The Administrator may accelerate the vesting of any portion of this Option. In that case, this Option will
be vested as of the date and to the extent specified by the Administrator. 
 4. Forfeiture upon Termination of Status as a Service
Provider. Upon the Participant’s termination as a Service Provider for any reason other than death or Disability, this Option will immediately stop vesting, and on the day that is 3 months following the Termination of Status Date (or any
earlier date on or following the Termination of Status Date determined by the Administrator), any portion of this Option that has not been exercised will be immediately forfeited for no consideration, subject to Applicable Laws. In the event of a
Participant’s Disability, vested Options shall be exercisable for 12 months after the Participants termination as a Service Provider (or until the Expiration Date if earlier), and in the event of a Participant’s death, vested Options shall
be exercisable for 18 months after the Participant’s termination as a Service Provider (or until the Expiration Date if earlier). The date of the Participant’s termination as a Service Provider is detailed in Section 3(c) of the Plan.

  
 - 3 - 

 5. Death of Participant. Any distribution or delivery to be made to the Participant under
this Agreement will, if he or she is then deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or her designated beneficiary. Any such transferee must furnish the Company with (a) written
notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations that apply to the transfer. 

6. Exercise of Option. 

(a) Right to Exercise. This Option may be exercised only before its Expiration Date and only under the Plan and this Agreement. 

(b) Method of Exercise. To exercise this Option, the Participant must deliver and the Administrator must receive an exercise notice
according to procedures determined by the Administrator. The exercise notice must: 
  

	 	(i)	state the number of Shares as to which this Option is being exercised (“Exercised Shares”), 

  

	 	(ii)	make any representations or agreements required by the Company, 

  

	 	(iii)	be accompanied by a payment of the total exercise price for all Exercised Shares, and 

  

	 	(iv)	be accompanied by a payment of all required Tax-Related Items (defined in Section 8(a) of this Agreement) for all Exercised Shares. 

The Option is exercised when both the exercise notice and payments due under Sections 6(b)(iii) and 6(b)(iv) have been received by the Company for all
Exercised Shares. The Administrator may designate a particular exercise notice to be used, but until a designation is made, the exercise notice attached to this Agreement as Exhibit C may be used. 

7. Method of Payment. The Participant may pay the exercise price for Exercised Shares by any of the following methods or a combination
of methods: 
 (a) cash; 
 (b)
check; 
 (c) wire transfer; 

(d) consideration received by the Company under a formal cashless exercise program adopted by the Company; or 

(e) surrender of other Shares, as long as the Company determines that accepting such Shares does not result in any adverse accounting
consequences to the Company. 

  
 - 4 - 

 
If Shares are surrendered, the value of those Shares will be the Fair Market Value for those Shares on the date they are surrendered. 

A non-U.S. resident’s methods of exercise may be restricted by the terms and condition of any appendix to this
Agreement for the Participant’s country (the “Appendix”). 
 8. Tax Obligations. 

(a) Tax Withholding. 
 (i)
No Shares will be issued to the Participant until he or she makes satisfactory arrangements (as determined by the Administrator) for the payment of income, employment, social security, payroll tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and legally applicable to him or her that the Administrator determines must be withheld (“Tax-Related
Items”), including those that result from the grant, vesting, or exercise of this Option, the subsequent sale of Shares acquired under this Option or the receipt of any dividends. If the Participant is a
non-U.S. employee, the method of payment of Tax-Related Items may be restricted by any Appendix. If the Participant fails to make satisfactory arrangements for the
payment of any Tax-Related Items under this Agreement at the time of an attempted Option exercise, the Company may refuse to honor the exercise and refuse to deliver the Shares. 

(ii) The Company has the right (but not the obligation) to satisfy any Tax-Related Items by
withholding from proceeds of a sale of Shares acquired upon the exercise of this Option arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent), and this will be the method by which such tax
withholding obligations are satisfied until the Company determines otherwise, subject to Applicable Laws. 
 (iii) The Company has the right
(but not the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to the Participant. 

(iv) The Participant authorizes the Company and/or any member(s) of the Company Group for whom he or she is performing services (each, an
“Employer”) to withhold any Tax-Related Items legally payable by the Participant from his or her wages or other cash compensation paid to the Participant by the Company and/or the Employer(s)
or from proceeds of the sale of Shares. 
 (v) Further, if the Participant is subject to taxation in more than one jurisdiction between the
Grant Date and the date of any relevant taxable or tax withholding event, the Company and/or the Employer(s) or former Employer(s) may withhold or account for tax in greater than one jurisdiction. 

(vi) Regardless of any action of the Company or the Employer(s), the Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The Participant further acknowledges that the Company and the
Employer(s) (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option; and (2) do not commit to and are under no
obligation to structure the terms of the grant or any aspect of this Option to reduce or eliminate his or her liability for Tax-Related Items or achieve any particular tax result. 

  
 - 5 - 

 (b) Tax Reporting. This Section 8(b) applies if the Participant is a U.S. taxpayer.
If this Option is partially or wholly an ISO, and if the Participant sells or otherwise disposes of any the Shares acquired by exercising the ISO portion on or before the later of (i) the date 2 years after the Grant Date, or (ii) the date
1 year after the date of exercise, he or she may be subject to reporting of Tax-Related Items by the Company on the compensation income recognized by him or her and must immediately notify the Company in
writing of the disposition. 
 9. Forfeiture or Clawback. This Option (including any proceeds, gains or other economic benefit
received by the Participant from any subsequent sale of Shares resulting from the exercise) will be subject to any compensation recovery or clawback policy implemented by the Company before or after the date of this Agreement. This includes any
clawback policy adopted to comply with the requirements of Applicable Laws. 
 10. Rights as Stockholder. The Participant’s
rights as a stockholder of the Company (including the right to vote and to receive dividends and distributions) will not begin until Shares have been issued and recorded on the records of the Company or its transfer agents or registrars. 

11. Acknowledgements and Agreements. The Participant’s signature on the Notice of Grant accepting this Option indicates that: 

(a) HE OR SHE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THIS OPTION IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER AND THAT BEING HIRED,
GRANTED THIS OPTION, AND EXERCISING THE OPTION WILL NOT RESULT IN VESTING. 
 (b) HE OR SHE FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION
AND AGREEMENT DO NOT CREATE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND DOES NOT INTERFERE IN ANY WAY WITH HIS OR HER RIGHT OR THE RIGHT OF THE EMPLOYER(S) TO
TERMINATE HIS OR HER RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE, SUBJECT TO APPLICABLE LAWS. 
 (c) The
Participant agrees that this Agreement and its incorporated documents reflect all agreements on its subject matters and that he or she is not accepting this Agreement based on any promises, representations, or inducements other than those reflected
in the Agreement. 
 (d) The Participant understands that exercise of this Option is governed strictly by Sections 6, 7, and 8 of this
Agreement and that failure to comply with those Sections could result in the expiration of this Option, even if an attempt was made to exercise. 

  
 - 6 - 

 (e) The Participant agrees that the Company’s delivery of any documents related to the Plan
or this Option (including the Plan, the Agreement, the Plan’s prospectus and any reports of the Company provided generally to the Company’s stockholders) to him or her may be made by electronic delivery, which may include the delivery of a
link to a Company intranet or the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail, or any other means of electronic delivery specified by the Company.
If the attempted electronic delivery of such documents fails, the Participant will be provided with a paper copy of the documents. The Participant acknowledges that he or she may receive from the Company a paper copy of any documents that were
delivered electronically at no cost to him or her by contacting the Company by telephone or in writing. The Participant may revoke his or her consent to the electronic delivery of documents or may change the electronic mail address to which such
documents are to be delivered (if the Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal service or
electronic mail. Finally, the Participant understands that he or she is not required to consent to electronic delivery of documents. 
 (f)
The Participant may deliver any documents related to the Plan or this Option to the Company by e-mail or any other means of electronic delivery approved by the Administrator, but he or she must provide the
Company or any designated third party administrator with a paper copy of any documents if his or her attempted electronic delivery of such documents fails. 

(g) The Participant accepts that all good faith decisions or interpretations of the Administrator regarding the Plan and Awards under the Plan
are binding, conclusive, and final. No member of the Administrator will be personally liable for any such decisions or interpretations. 

(h) The Participant agrees that the Plan is established voluntarily by the Company, is discretionary in nature, and may be amended, suspended,
or terminated by the Company at any time, to the extent permitted by the Plan. 
 (i) The Participant agrees that the grant of this Option is
voluntary and occasional and does not create any contractual or other right to receive future grants of options, or benefits in lieu of options, even if options have been granted in the past. 

(j) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(k) The Participant agrees that he or she is voluntarily participating in the Plan. 

(l) The Participant agrees that this Option and any Shares acquired under the Plan are not intended to replace any pension rights or

 - 7 - 

 (n) The Participant agrees that the future value of the Shares underlying this Option is unknown,
indeterminable, and cannot be predicted with certainty. 
 (o) The Participant understands that if the underlying Shares do not increase in
value, this Option will have no intrinsic monetary value. 
 (p) The Participant understands that if this Option is exercised, the value of
each Share received on exercise may increase or decrease in value, even below the Exercise Price per Share. 
 (q) The Participant agrees
that, for purposes of this Option, his or her engagement as a Service Provider is terminated as of the Termination of Status Date (regardless of the reason for such termination and whether or not the termination is later found to be invalid or in
breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or determined by the Administrator. 

(r) The Participant agrees that any right to vest in this Option terminates as of the Termination of Status Date and will not be extended by
any notice period (e.g., the period that he or she is a Service Provider would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws (including common law, if applicable)
in the jurisdiction where he or she is a Service Provider or by his or her service agreement or employment agreement, if any, unless he or she is providing bona fide services during such time). 

(s) The Participant agrees that the period during which the Participant may exercise the vested portion of this Option after a termination of
his or her status as a Service Provider (if any) will start as of the Termination of Status Date (regardless of the reason for such termination and whether or not the termination is later found to be invalid or in breach of employment laws in the
jurisdiction where he or she is a Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or determined by the Administrator.

services for purposes of this Option (including whether he or she is still considered to be providing services while on a leave of absence). 

(u) The Participant agrees that no member of the Company Group is liable for any foreign exchange rate fluctuation between the
Participant’s local currency and the United States Dollar that may affect the value of this Option or of any amounts due to him or her from the exercise of this Option or the subsequent sale of any Shares acquired upon exercise. 

(v) The Participant agrees that he or she has no claim or entitlement to compensation or damages from any forfeiture of this Option resulting
from the termination of his or her status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her
service agreement, if any), and in consideration of the grant of this 

  
 - 8 - 

 
Option to which he or she is otherwise not entitled, he or she irrevocably agrees never to institute any claim against the Company or any member of the Company Group, waives his or her ability
(if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such claim is nevertheless allowed by a court of competent jurisdiction, then the Participant’s participation in the
Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

12. Miscellaneous 
 (a)
Address for Notices. Any notice to be given to the Company under the terms of this Agreement must be addressed to the Company at Genprex, Inc., 100 Congress Avenue, Suite 2000, Austin, TX 78701 until the Company designates another address in

(c) Binding Agreement. If this Option is transferred, this Agreement will be binding upon and inure to the benefit of the heirs,
legatees, legal representatives, successors, and assigns of the parties to this Agreement. 
 (d) Additional Conditions to Issuance of
Stock. If the Company determines that the listing, registration, qualification, or rule compliance of the Common Stock on any securities exchange or under any state, federal, or foreign law or the tax code and related regulations or the consent
or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to the Participant (or his or her estate), the Company will try to meet the requirements of any such state, federal, or foreign
law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange, but the Shares will not be issued until such conditions have been met in a manner acceptable to the Company. 

(e) Captions. Captions provided in this Agreement are for convenience only and are not to serve as a basis for interpretation or
construction of this Agreement. 
 (f) Agreement Severable. If any provision of this Agreement is held invalid or unenforceable, that
provision will be severed from the remaining provisions of this Agreement and the invalidity or unenforceability will have no effect on the remainder of the Agreement. 

(g) Non-U.S. Appendix. This Option is subject to any special terms and conditions set forth in
any Appendix. If the Participant relocates to a country included in the Appendix, the special terms and conditions for that country will apply to him or her to the extent the Company determines that applying such terms and conditions is necessary or
advisable for legal or administrative reasons. 

  
 - 9 - 

 (h) Choice of Law; Choice of Forum. The Plan, this Agreement, this Option, and all

comply with Code Section 409A, to otherwise avoid imposition of any additional tax or income recognition under Code Section 409A in connection with this Option, or to comply with other Applicable Laws. 

(j) Waiver. The Participant acknowledges that a waiver by the Company of a breach of any provision of this Agreement will not operate or
be construed as a waiver of any other provision of this Agreement or of any subsequent breach of this Agreement by him or her.

 EXHIBIT B 

APPENDIX TO STOCK OPTION AGREEMENT 

Terms and Conditions 
 This Appendix to Stock
Option Agreement (the “Appendix”) includes additional terms and conditions that govern this Option granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or he or she
moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of September 1, 2017. Such Applicable Laws are often complex and change frequently. As a
result, the Company strongly recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the
time the Participant sells Shares acquired under the Plan. 
 In addition, the information contained in this Appendix is general in nature and may not apply
to the Participant’s particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country
may apply to his or her situation. 
 Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently
working, transfers employment after this Option is granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the
terms and conditions in this Appendix apply.

TERMS AND CONDITIONS OF RESTRICTED STOCK AWARD 

1. Grant. The Company grants the Participant an award of Restricted Stock as described in the Notice of Grant. If there is a conflict
between the Plan, this Agreement, or any other agreement with the Participant governing these Shares of Restricted Stock, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and
(c) any other agreement between the Company and the Participant governing these Shares of Restricted Stock. 
 2. Escrow of
Shares. 
 (a) Once the Participant signs this Agreement, all of these Shares of Restricted Stock will be delivered to an escrow holder
designated by the Company (the “Escrow Holder”) and will be held by the Escrow Holder until these Shares of Restricted Stock vest or the Participant ceases to be a Service Provider. 

(b) The Escrow Holder is not liable for any act it does or does not do for purposes of holding these Shares of Restricted Stock in escrow. 

(c) The Escrow Holder will transfer any vested Shares of Restricted Stock to the Participant at his or her request. 

(d) The Participant has no right to receive cash dividends on any of these Shares of Restricted Stock that are held in escrow but has all other
rights of a stockholder for such Shares, including the right to vote. 
 (e) These Shares of Restricted Stock will be subject to any
adjustments made according to Section 13(a) of the Plan. 
 (f) The Company may instruct the transfer agent for the Common Stock to
record the restrictions on transfer in this Agreement by placing a legend on the certificates representing the Restricted Stock or otherwise noting its records. 

3. Vesting. These Shares of Restricted Stock will vest only under the Vesting Schedule in the Notice of Grant, Section 4 of this
Agreement, or Section 14 of the Plan. Shares of Restricted Stock scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to be a Service Provider until the time such
vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

4. Administrator Discretion. The Administrator has the discretion to accelerate the vesting of any number of unvested Shares of
Restricted Stock at any time, subject to the terms of the Plan. In that case, those Shares of Restricted Stock will be vested as of the date specified by the Administrator. 

  
 - 3 - 

 5. Forfeiture upon Termination of Status as a Service Provider. Upon the
Participant’s termination as a Service Provider for any reason, these Shares of Restricted Stock will immediately stop vesting, and any of these Shares of Restricted Stock that have not yet vested will be forfeited by the Participant and
automatically transferred by the Escrow Holder to the Company at no cost to the Company, subject to Applicable Laws. The Participant will not be refunded any price paid for such Shares and will have no further rights under this Agreement. The
Participant appoints the Escrow Holder with full power of substitution (as the Participant’s true and lawful attorney-in-fact with irrevocable power and authority
in the name and on behalf of the Participant) to take any action and execute all documents and instruments, including stock powers necessary to transfer the certificate(s) evidencing such unvested Shares of Restricted Stock to the Company upon such
termination. The date of the Participant’s termination as a Service Provider is detailed in Section 3(c) of the Plan. 
 6.
Death of Participant. Any distribution or delivery to be made to the Participant under this Agreement will, if he or she is then deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or
her designated beneficiary. Any such transferee must furnish the Company with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with
any laws or regulations that apply to the transfer. 
 7. Tax Withholding. 

(a) No Shares of Restricted Stock may be released from escrow until the Participant makes satisfactory arrangements (as determined by the
Administrator) for the payment of income, employment, social security, payroll tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and
legally applicable to him or her that the Administrator determines must be withheld (“Tax-Related Items”), including those that result from the grant, vesting, or subsequent sale of Shares of
Restricted Stock or the receipt of any dividends. If the Participant is a non-U.S. employee, the method of payment of Tax-Related Items may be restricted by any
Appendix. If the Participant fails to make satisfactory arrangements for the payment of any Tax-Related Items under this Agreement when any of these Shares of Restricted Stock otherwise are supposed to vest or
Tax-Related Items related to these Shares of Restricted Stock otherwise are due, he or she will permanently forfeit the applicable Shares of Restricted Stock and such Shares of Restricted Stock will be
returned to the Company at no cost to the Company. 
 (b) The Company has the right (but not the obligation) to satisfy any Tax-Related Items by withholding from proceeds of a sale of any of these Shares of Restricted Stock that have vested arranged by the Company (on the Participant’s behalf pursuant to this authorization without
further consent), and this will be the method by which such tax withholding obligations are satisfied until the Company determines otherwise, subject to Applicable Laws. 

(c) The Company also has the right (but not the obligation) to satisfy any Tax-Related Items by
reducing the number of Shares otherwise deliverable to the Participant. 

  
 - 4 - 

 (d) Further, if the Participant is subject to taxation in more than one jurisdiction between the
Grant Date and the date of any relevant taxable or tax withholding event, the Company and/or any member of the Company Group for whom he or she is performing services (each, an “Employer”) or former Employer(s) may withhold or account for
tax in more than one jurisdiction. 
 (e) Regardless of any action of the Company or the Employer(s), the Participant acknowledges that the
ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The Participant further acknowledges that
the Company and the Employer(s) (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of these Shares of Restricted Stock and
(ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of these Shares of Restricted Stock to reduce or eliminate his or her liability for Tax-Related Items or
achieve any particular tax result. 
 8. Forfeiture or Clawback. These Shares of Restricted Stock (including any proceeds, gains or
other economic benefit received by the Participant from their subsequent sale) will be subject to any compensation recovery or clawback policy implemented by the Company before or after the date of this Agreement. This includes any clawback policy
adopted to comply with the requirements of Applicable Laws. 
 9. Rights as Stockholder. The Participant’s rights as a
stockholder of the Company (including the right to vote and to receive dividends and distributions) will not begin until these Shares of Restricted Stock have been issued and recorded on the records of the Company or its transfer agents or
registrars. 
 10. Acknowledgements and Agreements. The Participant’s signature on the Notice of Grant accepting these Shares of
Restricted Stock indicates that: 
 (a) HE OR SHE ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE SHARES OF RESTRICTED STOCK IS EARNED ONLY
BY CONTINUING AS A SERVICE PROVIDER AND THAT BEING HIRED OR BEING GRANTED THESE SHARES OF RESTRICTED STOCK DO NOT RESULT IN VESTING. 
 (b)
HE OR SHE FURTHER ACKNOWLEDGES AND AGREES THAT THESE SHARES OF RESTRICTED STOCK AND THIS AGREEMENT DO NOT CREATE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL AND DOES
NOT INTERFERE IN ANY WAY WITH HIS OR HER RIGHT OR THE RIGHT OF THE EMPLOYER(S) TO TERMINATE HIS OR HER RELATIONSHIP AS A SERVICE PROVIDER AT ANY TIME, WITH OR WITHOUT CAUSE, SUBJECT TO APPLICABLE LAWS. 

(c) The Participant agrees that this Agreement and its incorporated documents reflect all agreements on its subject matters and that he or she
is not accepting this Agreement based on any promises, representations, or inducements other than those reflected in the Agreement.

 (d) The Participant agrees that the Company’s delivery of any documents related to the Plan
or these Shares of Restricted Stock (including the Plan, the Agreement, the Plan’s prospectus, and any reports of the Company provided generally to the Company’s stockholders) to him or her may be made by electronic delivery, which may
include the delivery of a link to a Company intranet or to the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail, or any other means of electronic
delivery specified by the Company. If the attempted electronic delivery of such documents fails, the Participant will be provided with a paper copy of the documents. The Participant acknowledges that he or she may receive from the Company a paper
copy of any documents that were delivered electronically at no cost to him or her by contacting the Company by telephone or in writing. The Participant may revoke his or her consent to the electronic delivery of documents or may change the
electronic mail address to which such documents are to be delivered (if the Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail
address by telephone, postal service or electronic mail. Finally, the Participant understands that he or she is not required to consent to electronic delivery of documents. 

(e) The Participant may deliver any documents related to the Plan or these Shares of Restricted Stock to the Company by e-mail or any other means of electronic delivery approved by the Administrator, but he or she must provide the Company or any designated third party administrator with a paper copy of any documents if his or her
attempted electronic delivery of such documents fails. 
 (f) The Participant accepts that all good faith decisions or interpretations of the
Administrator regarding the Plan and Awards under the Plan are binding, conclusive, and final. No member of the Administrator will be personally liable for any such decisions or interpretations. 

(g) The Participant agrees that the Plan is established voluntarily by the Company, is discretionary in nature, and may be amended, suspended,
or terminated by the Company at any time, to the extent permitted by the Plan. 
 (h) The Participant agrees that the grant of these Shares
of Restricted Stock is voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock or benefits in lieu of restricted stock, even if restricted stock has been granted in the past. 

(i) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(j) The Participant agrees that he or she is voluntarily participating in the Plan. 

(k) The Participant agrees that these Shares of Restricted Stock are not intended to replace any pension rights or compensation. 

  
 - 6 - 

 (l) The Participant agrees that these Shares of Restricted Stock and their income and value are
not part of normal or expected compensation for any purpose, including for calculating any severance, resignation, termination, redundancy, dismissal, end-of-service
payments, bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits, or similar payments. 
 (m) The Participant
agrees that the future value of these Shares of Restricted Stock is unknown, indeterminable, and cannot be predicted with certainty. 
 (n)
The Participant agrees that, for purposes of these Shares of Restricted Stock, his or her engagement as a Service Provider is terminated as of the Termination of Status Date (regardless of the reason for such termination and whether or not the
termination is later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or
determined by the Administrator. 
 (o) The Participant agrees that any right to vest in these Shares of Restricted Stock terminates as of
the Termination of Status Date and will not be extended by any notice period (e.g., the period that he or she is a Service Provider would not include any contractual notice period or any period of “garden leave” or similar period mandated
under employment laws (including common law, if applicable) in the jurisdiction where he or she is a Service Provider or by his or her service agreement or employment agreement, if any, unless he or she is providing bona fide services during such
time). 
 (p) The Participant agrees that the Administrator has the exclusive discretion to determine when he or she is no longer actively
providing services for purposes of these Shares of Restricted Stock (including whether he or she is still considered to be providing services while on a leave of absence). 

(q) The Participant agrees that no member of the Company Group is liable for any foreign exchange rate fluctuation between the
Participant’s local currency and the United States Dollar that may affect the value of these Shares of Restricted Stock or of any amounts due to him or her upon the sale of any of these Shares of Restricted Stock. 

(r) The Participant agrees that he or she has no claim or entitlement to compensation or damages from any forfeiture of these Shares of
Restricted Stock resulting from the termination of his or her status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider
or the terms of his or her service agreement, if any), and in consideration of the grant of these Shares of Restricted Stock to which he or she is otherwise not entitled, he or she irrevocably agrees never to institute any claim against the Company
or any member of the Company Group, waives his or her ability (if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such claim is nevertheless allowed by a court of competent
jurisdiction, then the Participant’s participation in the Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request dismissal or withdrawal of such claim.

related regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of these Shares of Restricted Stock or their release from escrow to the Participant (or his or her

 EXHIBIT B 

APPENDIX TO RESTRICTED STOCK AGREEMENT 

Terms and Conditions 
 This Appendix to Restricted
Stock Agreement (the “Appendix”) includes additional terms and conditions that govern these Shares of Restricted Stock granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or
he or she moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of             , 20
    . Such Applicable Laws are often complex and change frequently. As a result, the Company strongly recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the
consequences of participation in the Plan because the information may be out of date at the time the Participant sells Shares acquired under the Plan. 
 In
addition, the information contained in this Appendix is general in nature and may not apply to the Participant’s particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised
to seek appropriate professional advice as to how the Applicable Laws in his or her country may apply to his or her situation. 
 Finally, if the
Participant is a citizen or resident of a country other than the one in which he or she is currently working, transfers employment after these Shares of Restricted Stock are granted, or is considered a resident of another country for local law
purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the terms and conditions in this Appendix apply.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT AWARD 

1. Grant. The Company grants the Participant an award of RSUs as described in the Notice of Grant. If there is a conflict between the
Plan, this Agreement, or any other agreement with the Participant governing these RSUs, those documents will take precedence and prevail in the following order: (a) the Plan, (b) the Agreement, and (c) any other agreement between the
Company and the Participant governing these RSUs. 
 2. Company’s Obligation to Pay. Each RSU is a right to receive a Share on
the date it vests. Until an RSU vests, the Participant has no right to payment of the Share. Before a vested RSU is paid, the RSU is an unsecured obligation of the Company, payable (if at all) only from the Company’s general assets. A vested
RSU will be paid to the Participant (or in the event of his or her death, to his or her estate) in whole Shares as soon as practicable after vesting (but no later than 60 days following the vesting date), subject to him or her satisfying any
obligations for Tax-Related Items (as defined in Section 7 of this Agreement) and any delay in payment required under Section 7 of this Agreement. The Participant cannot specify (directly or
indirectly) the taxable year of the payment of any vested RSU under this Agreement. 
 3. Vesting. These RSUs will vest only under
the Vesting Schedule in the Notice of Grant, Section 4 of this Agreement, or Section 14 of the Plan. RSUs scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest unless the Participant continues to
be a Service Provider until the time such vesting is scheduled to occur. The Administrator may modify the Vesting Schedule according to its authority under the Plan if the Participant takes a leave of absence or has a reduction in hours worked. 

4. Administrator Discretion. The Administrator has the discretion to accelerate the vesting of any RSUs at any time, subject to the
terms of the Plan. In that case, those RSUs will be vested as of the date specified by the Administrator. 
 5. Forfeiture upon
Termination of Status as a Service Provider. Upon the Participant’s termination as a Service Provider for any reason, these RSUs will immediately stop vesting, and on the 30th day following the Termination of Status Date (or any earlier
date on or following the Termination of Status Date determined by the Administrator), any of these RSUs that have not yet vested will be forfeited by the Participant, subject to Applicable Laws. The date of the Participant’s termination as a
Service Provider is detailed in Section 3(c) of the Plan. 
 6. Death of Participant. Any distribution or delivery to be made to
the Participant under this Agreement will, if he or she is then deceased, be made to the administrator or executor of his or her estate or, if the Administrator permits, his or her designated beneficiary. Any such transferee must furnish the Company
with (a) written notice of his or her status as transferee, and (b) evidence satisfactory to the Company to establish the validity of the transfer and compliance with any laws or regulations that apply to the transfer. 

  
 -1- 

 7. Tax Obligations. 

(a) Tax Withholding. 
 (i)
No Shares will be issued to the Participant until he or she makes satisfactory arrangements (as determined by the Administrator) for the payment of income, employment, social security, payroll tax, fringe benefit tax, payment on account, or other tax-related items related to his or her participation in the Plan and legally applicable to him or her that the Administrator determines must be withheld (“Tax-Related
Items”), including those that result from the grant, vesting, or payment of these RSUs, the subsequent sale of Shares acquired pursuant to such payment, or the receipt of any dividends. If the Participant is a
non-U.S. employee, the method of payment of Tax-Related Items may be restricted by any Appendix. If the Participant fails to make satisfactory arrangements for the
payment of any Tax-Related Items under this Agreement when any of these RSUs otherwise are supposed to vest or Tax-Related Items related to RSUs otherwise are due, he or
she will permanently forfeit the applicable RSUs and any right to receive Shares under such RSUs, and such RSUs will be returned to the Company at no cost to the Company. 

(ii) The Company has the right (but not the obligation) to satisfy any Tax-Related Items by
withholding from proceeds of a sale of Shares acquired upon payment of these RSUs arranged by the Company (on the Participant’s behalf pursuant to this authorization without further consent), and this will be the method by which such tax
withholding obligations are satisfied until the Company determines otherwise, subject to Applicable Laws. 
 (iii) The Company also has the
right (but not the obligation) to satisfy any Tax-Related Items by reducing the number of Shares otherwise deliverable to the Participant. 

(iv) Further, if the Participant is subject to taxation in more than one jurisdiction between the Grant Date and the date of any relevant
taxable or tax withholding event, the Company and/or any member of the Company Group for whom he or she is performing services (each, an “Employer”) or former Employer(s) may withhold or account for tax in more than one jurisdiction. 

(v) Regardless of any action of the Company or the Employer(s), the Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains his or her responsibility and may exceed the amount actually withheld by the Company or the Employer(s). The Participant further acknowledges that the Company and the
Employer(s) (1) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of these RSUs and (2) do not commit to and are under no
obligation to structure the terms of the grant or any aspect of these RSUs to reduce or eliminate his or her liability for Tax-Related Items or achieve any particular tax result. 

(b) Code Section 409A. This Section 7(b) does not apply if the Participant is not a U.S. taxpayer. 

(i) If the vesting of any RSUs is accelerated in connection with a termination of the Participant’s status as a Service Provider that is
a “separation from service” within the meaning of Code Section 409A and (x) the Participant is a “specified employee” within the meaning of Code Section 409A at that time and (y) the payment of such
accelerated RSUs would result in the imposition of additional tax under Code Section 409A if paid to the Participant within the 6-month period following such termination, then the accelerated RSUs will
not be paid until the first day after the 6-month period ends. 

  
 -2- 

 (ii) If the Participant’s status as a Service Provider terminates due to death or the
Participant dies after he or she stops being a Service Provider, the delay under Section 7(b)(i) of this Agreement will not apply, and these RSUs will be paid in Shares to the Participant’s estate as soon as practicable. 

(iii) All payments and benefits under this Agreement are intended to be exempt from Code Section 409A or comply with any requirements
necessary to avoid the imposition of additional tax under Code Section 409A(a)(1)(B) so that none of these RSUs or Shares issuable upon the vesting of RSUs will be subject to the additional tax imposed under Code Section 409A, and any
ambiguities will be interpreted according to that intent. 
 (iv) Each payment under this Agreement is a separate payment under Treasury
Regulations Section 1.409A-2(b)(2). 
 8. Forfeiture or Clawback. These RSUs (including
any proceeds, gains or other economic benefit received by the Participant from any subsequent sale of Shares issued upon payment of the RSUs) will be subject to any compensation recovery or clawback policy implemented by the Company before or after

 (d) The Participant agrees that the Company’s delivery of any documents related to the Plan
or these RSUs (including the Plan, the Agreement, the Plan’s prospectus, and any reports of the Company provided generally to the Company’s stockholders) to him or her may be made by electronic delivery, which may include the delivery of a
link to a Company intranet or to the Internet site of a third party involved in administering the Plan, the delivery of the document via e-mail, or any other means of electronic delivery specified by the
Company. If the attempted electronic delivery of such documents fails, the Participant will be provided with a paper copy of the documents. The Participant acknowledges that he or she may receive from the Company a paper copy of any documents that
were delivered electronically at no cost to him or her by contacting the Company by telephone or in writing. The Participant may revoke his or her consent to the electronic delivery of documents or may change the electronic mail address to which
such documents are to be delivered (if the Participant has provided an electronic mail address) at any time by notifying the Company of such revoked consent or revised e-mail address by telephone, postal
service or electronic mail. Finally, the Participant understands that he or she is not required to consent to electronic delivery of documents. 

(e) The Participant may deliver any documents related to the Plan or these RSUs to the Company by

her attempted electronic delivery of such documents fails.

the Administrator regarding the Plan and Awards under the Plan are binding, conclusive, and final. No member of the Administrator will be personally liable for any such decisions or interpretations.

or terminated by the Company at any time, to the extent permitted by the Plan. 
 (h) The Participant agrees that the grant of these RSUs is
voluntary and occasional and does not create any contractual or other right to receive future grants of restricted stock units or benefits in lieu of restricted stock units, even if restricted stock units have been granted in the past. 

(i) The Participant agrees that any decisions regarding future Awards will be in the Company’s sole discretion. 

(j) The Participant agrees that he or she is voluntarily participating in the Plan.

bonuses, holiday pay, long-service awards, pension or retirement or welfare benefits, or similar payments.

 (m) The Participant agrees that the future value of the Shares underlying these RSUs is unknown,
indeterminable, and cannot be predicted with certainty. 
 (n) The Participant agrees that, for purposes of these RSUs, his or her engagement
as a Service Provider is terminated as of the Termination of Status Date (regardless of the reason for such termination and whether or not the termination is later found to be invalid or in breach of employment laws in the jurisdiction where he or
she is a Service Provider or the terms of his or her service agreement, if any), unless otherwise expressly provided in this Agreement or determined by the Administrator. 

(o) The Participant agrees that any right to vest in these RSUs terminates as of the Termination of Status Date and will not be extended by any
notice period (e.g., the period that he or she is a Service Provider would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws (including common law, if applicable) in
the jurisdiction where he or she is a Service Provider or by his or her service agreement or employment agreement, if any, unless he or she is providing bona fide services during such time). 

(p) The Participant agrees that the Administrator has the exclusive discretion to determine when he or she is no longer actively providing
services for purposes of these RSUs (including whether he or she is still considered to be providing services while on a leave of absence). 

(q) The Participant agrees that no member of the Company Group is liable for any foreign exchange rate fluctuation between the
Participant’s local currency and the United States Dollar that may affect the value of these RSUs or of any amounts due to him or her from the payment of these RSUs or the subsequent sale of any Shares acquired upon such payment. 

(r) The Participant agrees that he or she has no claim or entitlement to compensation or damages from any forfeiture of these RSUs resulting
from the termination of his or her status as a Service Provider (for any reason whatsoever, whether or not later found to be invalid or in breach of employment laws in the jurisdiction where he or she is a Service Provider or the terms of his or her
service agreement, if any), and in consideration of the grant of these RSUs to which he or she is otherwise not entitled, he or she irrevocably agrees never to institute any claim against the Company or any member of the Company Group, waives his or
her ability (if any) to bring any such claim, and releases the Company and all members of the Company Group from any such claim. If any such claim is nevertheless allowed by a court of competent jurisdiction, then the Participant’s
participation in the Plan constitutes his or her irrevocable agreement to not pursue such claim and to execute any and all documents necessary to request dismissal or withdrawal of such claim.

Conditions to Issuance of Stock. If the Company determines that the listing, registration, qualification, or rule compliance of the Common Stock on any securities exchange or under any state, federal, or foreign law or the tax code and related
regulations or the consent or approval of any governmental regulatory authority is necessary or desirable as a condition to the issuance of Shares to the Participant (or his or her estate), the Company will try to meet the requirements of any such
state, federal, or foreign law or securities exchange and to obtain any such consent or approval of any such governmental authority or securities exchange, but the Shares will not be issued until such conditions have been met in a manner acceptable
to the Company. 
 (e) Captions. Captions provided in this Agreement are for convenience only and are not to serve as a basis for
interpretation or construction of this Agreement.

unenforceable, that provision will be severed from the remaining provisions of this Agreement and the invalidity or unenforceability will have no effect on the remainder of the Agreement. 

(g) Non-U.S. Appendix. These RSUs are subject to any special terms and conditions set forth in
any appendix to this Agreement for the Participant’s country (the “Appendix”). If the Participant relocates to a country included in the Appendix, the special terms and conditions for that country will apply to him or her to
the extent the Company determines that applying such terms and conditions is necessary or advisable for legal or administrative reasons. 

(h) Choice of Law; Choice of Forum. The Plan, this Agreement, these RSUs, and all determinations made and actions taken under the Plan,
to the extent not otherwise governed by the laws of the United States, will be governed by the laws of the State of Delaware without giving effect to principles of conflicts of law. For purposes of litigating any dispute that arises under the Plan,

necessary or advisable, in its sole discretion and without the consent of the Participant, to comply with Code Section 409A, to otherwise avoid imposition of any additional tax or income recognition under Code Section 409A in connection
with these RSUs, or to comply with other Applicable Laws.

 EXHIBIT B 

APPENDIX TO RESTRICTED STOCK UNIT AGREEMENT 

Terms and Conditions 
 This Appendix to Restricted
Stock Unit Agreement (the “Appendix”) includes additional terms and conditions that govern these RSUs granted to the Participant under the Plan if he or she resides in one of the countries listed below on the Grant Date or he or she
moves to one of the listed countries. 
 Notifications 

This Appendix may also include information regarding exchange controls and certain other issues of which the Participant should be aware with respect to
participation in the Plan. The information is based on the securities, exchange control, and other Applicable Laws in effect in the respective countries as of September 1, 2017. Such Applicable Laws are often complex and change frequently. As a
result, the Company strongly recommends that the Participant not rely on the information in this Appendix as the only source of information relating to the consequences of participation in the Plan because the information may be out of date at the
time the Participant sells Shares acquired under the Plan. 
 In addition, the information contained in this Appendix is general in nature and may not apply
to the Participant’s particular situation, and the Company is not in a position to assure him or her of a particular result. The Participant is advised to seek appropriate professional advice as to how the Applicable Laws in his or her country
may apply to his or her situation. 
 Finally, if the Participant is a citizen or resident of a country other than the one in which he or she is currently
working, transfers employment after these RSUs are granted, or is considered a resident of another country for local law purposes, the information in this Appendix may not apply to him or her, and the Administrator will determine to what extent the
terms and conditions in this Appendix apply.
