 Exhibit 10.1 

DROPBOX, INC. 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is dated as of
                     , and is between Dropbox, Inc., a Delaware corporation (the “Company”), and
                     (“Indemnitee”). 

RECITALS 
 A.
Indemnitee’s service to the Company substantially benefits the Company. 
 B. Individuals are reluctant to serve as directors or
officers of corporations or in certain other capacities unless they are provided with adequate protection through insurance or indemnification against the risks of claims and actions against them arising out of such service. 

C. Indemnitee does not regard the protection currently provided by applicable law, the Company’s governing documents and any insurance as
adequate under the present circumstances, and Indemnitee may not be willing to serve as a director or officer without additional protection. 

D. In order to induce Indemnitee to continue to provide services to the Company, it is reasonable, prudent and necessary for the Company to
contractually obligate itself to indemnify, and to advance expenses on behalf of, Indemnitee as permitted by applicable law. 
 E. This
Agreement is a supplement to and in furtherance of the indemnification provided in the Company’s certificate of incorporation and bylaws, and any resolutions adopted pursuant thereto, and this Agreement shall not be deemed a substitute
therefor, nor shall this Agreement be deemed to limit, diminish or abrogate any rights of Indemnitee thereunder. 
 The parties therefore
agree as follows: 
 1. Definitions.  

(a) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any
of the following events: 
 (i) Acquisition of Stock by Third Party. Any Person (as defined below) becomes the Beneficial Owner (as
defined below), directly or indirectly, of securities of the Company representing fifteen percent (15%) or more of the combined voting power of the Company’s then outstanding securities; 

(ii) Change in Board Composition. During any period of two consecutive years (not including any period prior to the execution of this
Agreement), individuals who at the beginning of such period constitute the Company’s board of directors, and any new directors (other than a director designated by a person who has entered into an agreement with the Company to effect a
transaction described in Sections 1(a)(i), 1(a)(iii) or 1(a)(iv)) whose election by the board of directors or nomination for election by the Company’s stockholders was approved by a vote of at least
two-thirds of the directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to
constitute at least a majority of the members of the Company’s board of directors; 

 (iii) Corporate Transactions. The effective date of a merger or consolidation of the
Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or
by being converted into voting securities of the surviving entity) more than 50% of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and with the power to elect at
least a majority of the board of directors or other governing body of such surviving entity; 
 (iv) Liquidation. The approval
by the stockholders of the Company of a complete liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; and 

(v) Other Events. Any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended, whether or not the Company is then subject to such reporting requirement, except the
completion of the Company’s initial public offering shall not be considered a Change in Control. 
 For purposes of this
Section 1(a), the following terms shall have the following meanings: 
 (1) “Person” shall have the meaning as
set forth in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended; provided, however, that “Person” shall exclude (i) the Company, (ii) any trustee or other fiduciary holding
securities under an employee benefit plan of the Company, and (iii) any corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company. 

(2) “Beneficial Owner” shall have the meaning given to such term in
Rule 13d-3 under the Securities Exchange Act of 1934, as amended; provided, however, that “Beneficial Owner” shall exclude any Person otherwise becoming a Beneficial Owner
by reason of (i) the stockholders of the Company approving a merger of the Company with another entity or (ii) the Company’s board of directors approving a sale of securities by the Company to such Person. 

(b) “Corporate Status” describes the status of a person who is or was a director, trustee, general partner, managing
member, officer, employee, agent or fiduciary of the Company or any other Enterprise. 
 (c) “DGCL” means the General
Corporation Law of the State of Delaware. 
 (d) “Disinterested Director” means a director of the Company who is not
and was not a party to the Proceeding in respect of which indemnification is sought by Indemnitee.

Company as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary. 
 (f)
“Expenses” include all reasonable and actually incurred attorneys’ fees, retainers, court costs, transcript costs, fees and costs of experts, witness fees, travel expenses, duplicating costs, printing and binding costs,

Indemnitee under this Agreement, or other indemnitees under similar indemnification agreements), 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. 
 (h) “Proceeding” means any threatened, pending or
completed action, suit, arbitration, mediation, alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or proceeding, whether brought in the right of the Company or otherwise and whether of a civil, criminal,
administrative or investigative nature, including any appeal therefrom and including without limitation any such Proceeding pending as of the date of this Agreement, in which Indemnitee was, is or will be involved as a party, a potential party, a non-party witness or otherwise by reason of (i) the fact that Indemnitee is or was a director or officer of the Company, (ii) any action taken by Indemnitee or any action or inaction on Indemnitee’s
part while acting as a director or officer of the Company, or (iii) the fact that he or she is or was serving at the request of the Company as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of the
Company or any other Enterprise, in each case whether or not serving in such capacity at the time any liability or Expense is incurred for which indemnification or advancement of expenses can be provided under this Agreement.

Company” as referred to in this Agreement. 
 2. Indemnity in Third-Party Proceedings. The Company shall indemnify
Indemnitee in accordance with the provisions of this Section 2 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its
favor. Pursuant to this Section 2, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by Indemnitee or on his
or her behalf in connection with such Proceeding or any claim, issue or matter therein, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company and, with respect to
any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was unlawful. 

  
 -3- 

 3. Indemnity in Proceedings by or in the Right of the Company. The Company shall indemnify
Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection with such Proceeding or any claim,
issue or matter therein, if Indemnitee acted in good faith and in a manner he or she 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 in respect
of any claim, issue or matter as to which Indemnitee shall have been adjudged by a court of competent jurisdiction to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery 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 for such expenses as the Delaware Court of
Chancery or such other court shall deem proper. 
 4. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. To the extent that Indemnitee is a party to or a participant in and is successful (on the merits or otherwise) in defense of any Proceeding or any claim, issue or matter therein, the Company shall indemnify Indemnitee against all
Expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. For purposes of this section, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice,
shall be deemed to be a successful result as to such claim, issue or matter. 
 5. Indemnification for Expenses of a Witness. To the
extent that Indemnitee is, by reason of his or her Corporate Status, a witness in any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified to the extent permitted by applicable law against all Expenses actually and
reasonably incurred by Indemnitee or on Indemnitee’s behalf in connection therewith. 
 6. Additional Indemnification. 

(a) Notwithstanding any limitation in Sections 2, 3 or 4, the Company shall indemnify Indemnitee to the fullest extent permitted by
applicable law if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines and
amounts paid in settlement actually and reasonably incurred by Indemnitee or on his or her behalf in connection with the Proceeding or any claim, issue or matter therein. 

(b) For purposes of Section 6(a), the meaning of the phrase “to the fullest extent permitted by applicable law”
shall include, but not be limited to: 
 (i) the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 
 (ii) the
fullest extent authorized or permitted by any amendments to or replacements of the DGCL adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 

  
 -4- 

 7. Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be
obligated under this Agreement to make any indemnity in connection with any Proceeding (or any part of any Proceeding): 
 (a) for which
payment has actually been made to or on behalf of Indemnitee under any statute, insurance policy, indemnity provision, vote or otherwise, except with respect to any excess beyond the amount paid; 

(b) for an accounting or disgorgement of profits pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended, or similar
provisions of federal, state or local statutory law or common law, if Indemnitee is held liable therefor (including pursuant to any settlement arrangements); 

(c) for any reimbursement of the Company by Indemnitee of any bonus or other incentive-based or equity-based compensation or of any profits
realized by Indemnitee from the sale of securities of the Company, as required in each case under the Securities Exchange Act of 1934, as amended (including any such reimbursements that arise from an accounting restatement of the Company pursuant to
Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the
Sarbanes-Oxley Act), if Indemnitee is held liable therefor (including pursuant to any settlement arrangements); 
 (d) initiated by
Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees, agents or other indemnitees, unless (i) the Company’s board of directors authorized the
Proceeding (or the relevant part of the Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law, (iii) otherwise
authorized in Section 12 or (iv) otherwise required by applicable law; or 
 (e) if prohibited by applicable law. 

8. Advances of Expenses. The Company shall advance the Expenses incurred by Indemnitee in connection with any Proceeding prior to its
final disposition, and such advancement shall be made as soon as reasonably practicable, but in any event no later than 90 days, after the receipt by the Company of a written statement or statements requesting such advances from time to time (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 expenditure made that would cause Indemnitee to waive any
privilege accorded by applicable law shall not be included with the invoice). Advances shall be unsecured and interest free and made without regard to Indemnitee’s ability to repay such advances. Indemnitee hereby undertakes to repay any
advance to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company, and no other form of undertaking shall be required other than the execution of this Agreement. This Section 8 shall not
apply to the extent advancement is prohibited by law and shall not apply to any Proceeding (or any part of any Proceeding) for which indemnity is not permitted under this Agreement, but shall apply to any Proceeding (or any part of any Proceeding)
referenced in Section 7(b) or 7(c) prior to a determination that Indemnitee is not entitled to be indemnified by the Company. 
 9.
Procedures for Notification and Defense of Claim. 
 (a) Indemnitee shall notify the Company in writing of any matter with respect to
which Indemnitee intends to seek indemnification or advancement of Expenses as soon as reasonably practicable following the receipt by Indemnitee of notice thereof. The written notification to the Company shall include, in reasonable detail, a
description of the nature of the Proceeding and the facts underlying the Proceeding. The failure by Indemnitee to notify the Company will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under
this Agreement, and any delay in so notifying the Company shall not constitute a waiver by Indemnitee of any rights, except to the extent that such failure or delay materially prejudices the Company. 

  
 -5- 

 (b) If, at the time of the receipt of a notice of a Proceeding pursuant to the terms hereof, the
Company has directors’ and officers’ liability insurance in effect that may be applicable to the Proceeding, the Company shall give prompt notice of the commencement of the Proceeding to the insurers in accordance with the procedures set
forth in the applicable policies. The Company shall thereafter take all commercially-reasonable 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. 
 (c) In the event the Company may be obligated to make any indemnity in connection with a Proceeding, the Company shall be
entitled to assume the defense of such Proceeding with counsel approved by Indemnitee, which approval shall not be unreasonably withheld, conditioned or delayed, upon the delivery to Indemnitee of written notice of its election to do so. After
delivery of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee for any fees or expenses of counsel subsequently incurred by Indemnitee with respect to
the same Proceeding. Notwithstanding the Company’s assumption of the defense of any such Proceeding, the Company shall be obligated to pay the fees and expenses of Indemnitee’s separate counsel to the extent (i) the employment of
separate counsel by Indemnitee is authorized by the Company, (ii) counsel for the Company or Indemnitee shall have reasonably concluded that there is a conflict of interest between the Company and Indemnitee in the conduct of any such defense
such that Indemnitee needs to be separately represented, (iii) the Company is not financially or legally able to perform its indemnification obligations, or (iv) the Company shall not have retained, or shall not continue to retain, counsel
to defend such Proceeding. Regardless of any provision in this Agreement, Indemnitee shall have the right to employ counsel in any Proceeding at Indemnitee’s personal expense. The Company shall not be entitled, without the consent of
Indemnitee, to assume the defense of any claim brought by or in the right of the Company. 
 (d) Indemnitee shall give the Company such
information and cooperation in connection with the Proceeding as may be reasonably appropriate. 
 (e) The Company shall not be liable to
indemnify Indemnitee for any settlement of any Proceeding (or any part thereof) without the Company’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. 

(f) The Company shall not settle any Proceeding (or any part thereof) in a manner that imposes any penalty or liability on Indemnitee without
Indemnitee’s prior written consent, which shall not be unreasonably withheld, conditioned or delayed. 
 10. Procedures upon
Application for Indemnification.  
 (a) To obtain indemnification, Indemnitee shall submit to the Company a written request,
including therein or therewith such documentation and information as is reasonably available to Indemnitee and as is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification following the final
disposition of the Proceeding. The Company shall, as soon as reasonably practicable after receipt of such a request for indemnification, advise the board of directors that Indemnitee has requested indemnification. Any delay in providing the request
will not relieve the Company from its obligations under this Agreement, except to the extent such failure is prejudicial. 
 (b) Upon written
request by Indemnitee for indemnification pursuant to Section 10(a), a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case (i) if a Change in Control shall have occurred, by Independent
Counsel in a written opinion to the Company’s board of directors, a copy of which shall be delivered to Indemnitee or (ii) if a Change in Control shall not have occurred, (A) by a majority vote of the Disinterested Directors, even
though less than a quorum of the Company’s board of directors, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the Company’s board of
directors, (C) if there 

  
 -6- 

 
are no such Disinterested Directors or, if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be
delivered to Indemnitee or (D) if so directed by the Company’s board of directors, by the stockholders of the Company. If it is determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within thirty
days after such determination. Indemnitee shall cooperate with the person, persons or entity making the determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon
reasonable advance request any documentation or information that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any costs or expenses (including
attorneys’ fees and disbursements) actually and reasonably incurred by Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company, to the extent permitted by applicable law. 

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(b), the
Independent Counsel shall be selected as provided in this Section 10(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Company’s board of directors, and the Company shall give written
notice to Indemnitee advising him or her of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection
be made by the Company’s board of directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event,
Indemnitee or the Company, as the case may be, may, within ten days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided,
however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 1 of this Agreement, and the objection shall
set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so
selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after the later of (i) submission by Indemnitee of a written request
for indemnification pursuant to Section 10(a) hereof and (ii) the final disposition of the Proceeding, the parties have not agreed upon an Independent Counsel, either the Company or Indemnitee may petition the Delaware Court of Chancery
for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and for the appointment as Independent Counsel of a person selected by the court or by such other person as
the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent Counsel under Section 10(b) hereof. Upon the due commencement of any judicial proceeding or
arbitration pursuant to Section 12(a) of this Agreement, the Independent Counsel shall be discharged and relieved of any further responsibility in such capacity (subject to the applicable standards of professional conduct then prevailing). 

(d) The Company agrees to pay the reasonable fees and expenses of any Independent Counsel. 

11. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such determination
shall, to the fullest extent not prohibited by law, presume that Indemnitee is entitled to indemnification under this Agreement, and the Company shall, to the fullest extent not prohibited by law, have the burden of proof to overcome that
presumption by clear and convincing evidence. 

  
 -7- 

 (b) The termination of any Proceeding or of any claim, issue or matter therein, by judgment,
order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create
a presumption that Indemnitee did not act in good faith and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable
cause to believe that his or her conduct was unlawful. 
 (c) For purposes of any determination of good faith, Indemnitee shall be deemed to
have acted in good faith to the extent Indemnitee relied in good faith on (i) the records or books of account of the Enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Enterprise in
the course of their duties, (iii) the advice of legal counsel for the Enterprise or its board of directors or counsel selected by any committee of the board of directors or (iv) information or records given or reports made to the
Enterprise by an independent certified public accountant, an appraiser, investment banker or other expert selected with reasonable care by the Enterprise or its board of directors or any committee of the board of directors. The provisions of this
Section 11(c) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met any applicable standard of conduct. 

(d) Neither the knowledge, actions nor failure to act of any other director, officer, agent or employee of the Enterprise shall be imputed to
Indemnitee for purposes of determining the right to indemnification under this Agreement. 
 12. Remedies of Indemnitee.

 (a) Subject to Section 12(e), in the event that (i) a determination is made pursuant to Section 10 of this Agreement that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8 or 12(d) of this Agreement, (iii) no determination of entitlement to indemnification shall have
been made pursuant to Section 10 of this Agreement within 90 days after the later of the receipt by the Company of the request for indemnification or the final disposition of the Proceeding, (iv) payment of indemnification pursuant to this
Agreement is not made (A) within thirty days after a determination has been made that Indemnitee is entitled to indemnification or (B) with respect to indemnification pursuant to Sections 4, 5 and 12(d) of this Agreement, within
thirty days after receipt by the Company of a written request therefor, or (v) the Company or any other person or entity takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or
other action or proceeding designed to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication by the Delaware Court of Chancery of his or her
entitlement to such indemnification or advancement of Expenses. Alternatively, Indemnitee, at his or her option, may seek an award in arbitration with respect to his or her entitlement to such indemnification or advancement of Expenses, to be
conducted by a single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on
which Indemnitee first has the right to commence such proceeding pursuant to this Section 12(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration in accordance with this Agreement. 

(b) Neither (i) the failure of the Company, its board of directors, any committee or subgroup of the board of directors, Independent
Counsel or stockholders to have made a determination that indemnification of Indemnitee is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual determination by the Company, its board of
directors, any committee or subgroup of the board of directors, Independent Counsel or stockholders that Indemnitee has not met the applicable standard of conduct, shall create a presumption that Indemnitee has or has not met the applicable standard
of conduct. In the event that a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section 12
shall be conducted in all respects as a de novo trial, or arbitration, on 

  
 -8- 

 
the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any judicial proceeding or arbitration commenced pursuant to this Section 12, the Company
shall, to the fullest extent not prohibited by law, have the burden of proving Indemnitee is not entitled to indemnification or advancement of Expenses, as the case may be, by clear and convincing evidence. 

(c) To the fullest extent not prohibited by law, the Company shall be precluded from asserting in any judicial proceeding or arbitration
commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the
provisions of this Agreement. If a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding or
arbitration commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statements not materially misleading, in connection with
the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 
 (d) To the extent not prohibited
by law, the Company shall indemnify Indemnitee against all Expenses that are incurred by Indemnitee in connection with any action for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and
officers’ liability insurance policies maintained by the Company to the extent Indemnitee is successful in such action, and, if requested by Indemnitee, shall (as soon as reasonably practicable, but in any event no later than 90 days, after
receipt by the Company of a written request therefor) advance such Expenses to Indemnitee, subject to the provisions of Section 8. 

(e) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification shall be required to be
made prior to the final disposition of the Proceeding. 
 13. Contribution. To the fullest extent permissible under applicable law, if
the indemnification provided for in this Agreement is unavailable to Indemnitee, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amounts incurred by Indemnitee, whether for Expenses, judgments, fines or amounts paid or to be
paid in settlement, in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the
relative benefits received by the Company and Indemnitee as a result of the events and transactions giving rise to such Proceeding; and (ii) the relative fault of Indemnitee and the Company (and its other directors, officers, employees and
agents) in connection with such events and transactions. 
 14. Non-exclusivity. The rights of
indemnification and to receive advancement of Expenses as provided by this Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Company’s certificate of
incorporation or bylaws, any agreement, a vote of stockholders or a resolution of directors, or otherwise. To the extent that a change in Delaware law, 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 and 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, subject to the restrictions expressly set forth herein or therein. Except as expressly set forth herein, 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. Except as expressly set forth herein, the assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

  
 -9- 

 15. Primary Responsibility. The Company acknowledges that Indemnitee has certain rights to
indemnification and advancement of expenses provided by [insert name of fund] [and certain affiliates thereof] (collectively, the “Secondary Indemnitor[s]”). The Company agrees that, as between the Company and the
Secondary Indemnitor[s], the Company is primarily responsible for amounts required to be indemnified or advanced under the Company’s certificate of incorporation or bylaws or this Agreement and any obligation of the Secondary Indemnitor[s] to
provide indemnification or advancement for the same amounts is secondary to those Company obligations. To the extent not in contravention of any insurance policy or policies providing liability or other insurance for the Company or any director,
trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise, the Company waives any right of contribution or subrogation against the Secondary Indemnitor[s] with respect to the liabilities
for which the Company is primarily responsible under this Section 15. In the event of any payment by the Secondary Indemnitor[s] of amounts otherwise required to be indemnified or advanced by the Company under the Company’s certificate of
incorporation or bylaws or this Agreement, the Secondary Indemnitor[s] shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee for indemnification or advancement of expenses under the Company’s
certificate of incorporation or bylaws or this Agreement or, to the extent such subrogation is unavailable and contribution is found to be the applicable remedy, shall have a right of contribution with respect to the amounts paid; provided,
however, that the foregoing sentence will be deemed void if and to the extent that it would violate any applicable insurance policy. The Secondary Indemnitor[s] [are][is an] express third-party [beneficiaries][beneficiary] of the terms of this
Section 15. 
 16. No Duplication of Payments. The Company shall not be liable under this Agreement to make any payment of
amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received payment for such amounts under any insurance policy, contract, agreement or otherwise.

 17. Insurance. To the extent that the Company maintains an insurance policy or policies providing liability insurance for
directors, trustees, general partners, managing members, officers, employees, agents or fiduciaries of the Company or any other Enterprise, Indemnitee shall be covered by such policy or policies to the same extent as the most favorably-insured
persons under such policy or policies in a comparable position. 
 18. Subrogation. In the event of any 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 shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are
necessary to enable the Company to bring suit to enforce such rights. 
 19. Services to the Company. Indemnitee agrees to serve as a
director or officer of the Company or, at the request of the Company, as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of another Enterprise, for so long as Indemnitee is duly elected or appointed or
until Indemnitee tenders his or her resignation or is removed from such position. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or any obligation imposed by operation of law), in
which event the Company shall have no obligation under this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract between the Company (or any of its subsidiaries or any Enterprise) and
Indemnitee. Indemnitee specifically acknowledges that any employment with the Company (or any of its subsidiaries or any Enterprise) is at will, and Indemnitee may be discharged at any time for any reason, with or without cause, with or without
notice, except as may be otherwise expressly provided in any executed, written employment contract between Indemnitee and the Company (or any of its subsidiaries or any Enterprise), any existing formal severance policies adopted by the
Company’s board of directors or, with respect to service as a director or officer of the Company, the Company’s certificate of incorporation or bylaws or the DGCL. No such document shall be subject to any oral modification thereof.

 20. Duration. This Agreement shall continue in effect until the later of (a) ten
years after the date that Indemnitee shall have ceased to serve as a director or an officer of the Company or as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of any other Enterprise, as applicable,
(b) for as long as Indemnitee may be subject to any Proceeding, even after Indemnitee has ceased to serve as a director or officer of the Company or as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary
of any other Enterprise, as applicable. 
 21. Successors. This Agreement shall be binding upon the Company and its successors and
assigns, including any direct or indirect successor, by purchase, merger, consolidation or otherwise, to all or substantially all of the business or assets of the Company, and shall inure to the benefit of Indemnitee and Indemnitee’s heirs,
executors and administrators. The Company shall require and cause 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, by written agreement,
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. 

22. Severability. Nothing in this Agreement is intended to require or shall be construed as requiring the Company to do or fail to do
any act in violation of applicable law. The Company’s inability, pursuant to court order or other applicable law, to perform its obligations under this Agreement shall not constitute a breach of this Agreement. If any provision or provisions of
this Agreement shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (i) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, each portion of any
section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby and shall remain enforceable to the
fullest extent permitted by law; (ii) such provision or provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum effect to the intent of the parties hereto; and (iii) to the fullest
extent possible, the provisions of this Agreement (including, without limitation, each portion of any section of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or
unenforceable) shall be construed so as to give effect to the intent manifested thereby. 
 23. Enforcement. The Company expressly
confirms and agrees that it has entered into this Agreement and assumed the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and the Company acknowledges that Indemnitee is relying upon
this Agreement in serving as a director or officer of the Company. 
 24. Entire Agreement. This Agreement constitutes the entire
agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof; provided,
however, that this Agreement is a supplement to and in furtherance of the Company’s certificate of incorporation and bylaws and applicable law. 

25. Modification and Waiver. No supplement, modification or amendment to this Agreement shall be binding unless executed in writing by
the parties hereto. No amendment, alteration or repeal of this Agreement shall adversely affect 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. No waiver of any of the provisions of this Agreement shall constitute or be deemed a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing waiver.

 1.    Purposes of the Plan. The purposes of this Plan are: 

 

	 	•	 	to attract and retain the best available personnel for positions of substantial responsibility,

requirements relating to the administration of equity-based awards and the related issuance of Shares thereunder, including but not limited to U.S. federal and state corporate laws, U.S. federal and state securities laws, the Code, any stock
exchange or quotation system on which the Common Stock is listed or quoted and the applicable laws of any non-U.S. country or jurisdiction where Awards are, or will be, granted under the Plan.

Rights, Restricted Stock, Restricted Stock Units, Performance Units or Performance Shares.

(e)    “Board” means the Board of Directors of the Company. 

(f)    “Change in Control” means the occurrence of any of the following events: 

(i)    A change in the ownership of the Company which occurs on the date that any one person, or more than one
person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the
Company; provided, however, that for purposes of this subsection, (A) the acquisition of additional stock by any one Person, who is 

 considered to own more than fifty percent (50%) of the total voting power of the stock of the Company will
not be considered a Change in Control, and (B) if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership
of shares of the Company’s voting stock immediately prior to the change in ownership, the direct or indirect beneficial ownership of fifty percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent
entity of the Company, such event will not be considered a Change in Control under this subsection (i). For this purpose, indirect beneficial ownership will include, without limitation, an interest resulting from ownership of the voting securities
of one or more corporations or other business entities which own the Company, as the case may be, either directly or through one or more subsidiary corporations or other business entities; or 

(ii)    A change in the effective control of the Company which occurs on the date that a majority of members of the Board
is replaced during any twelve (12)-month period by Directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of this subsection (ii), if any
Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same Person will not be considered a Change in Control; or 

(iii)    A change in the ownership of a substantial portion of the Company’s assets which occurs on the date that
any Person acquires (or has acquired during the twelve (12)-month period ending on the date of the most recent acquisition by such person or persons) assets from the Company that have a total gross
fair market value equal to or more than fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection
(iii), the following will not constitute a change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or
(B) a transfer of assets by the Company to: (1) a stockholder of the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of

market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. 

For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a
merger, consolidation, purchase or acquisition of stock, or similar business transaction with the Company. 
 Notwithstanding the
foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Section 409A.

 Further and for the avoidance of doubt, a transaction will not constitute a Change in Control
if: (i) its sole purpose is to change the state of the Company’s incorporation, or (ii) its sole purpose is to create a holding company that will be owned in substantially the same proportions by the persons who held the
Company’s securities immediately before such transaction. 
 (g)    “Code” means the Internal
Revenue Code of 1986, as amended. Reference to a specific section of the Code or regulation thereunder will include such section or regulation, any valid regulation promulgated under such section, and any comparable provision of any future

initial public offering of the Company’s Common Stock. 
 (ii)    For purposes of any Awards granted on any other
date, the Fair Market Value will be the closing sales price for Common Stock as quoted on any established stock exchange or national market system (including without limitation the New York Stock Exchange, NASDAQ Global Select Market, the NASDAQ
Global Market or the NASDAQ Capital Market of The NASDAQ Stock Market) on which the Common Stock is listed on the date of determination (or the closing bid, if no sales were reported), as reported in The Wall Street Journal or such other
source as the Administrator deems reliable. If the determination date for the Fair Market Value occurs on a non-trading day (i.e., a weekend or holiday), the Fair Market Value will be such price on the
immediately preceding trading day, unless otherwise determined by the Administrator. In the absence of an established market for the Common Stock, the Fair Market Value thereof will be determined in good faith by the Administrator. 

The determination of fair market value for purposes of tax withholding may be made in the Administrator’s discretion subject to

 thereto will become available for future grant or sale under the Plan (unless the Plan has terminated). With
respect to Stock Appreciation Rights, only Shares actually issued (i.e., the net Shares issued) pursuant to a Stock Appreciation Right will cease to be available under the Plan; all remaining Shares under Stock Appreciation Rights will remain
available for future grant or sale under the Plan (unless the Plan has terminated). Shares that have actually been issued under the Plan under any Award will not be returned to the Plan and will not become available for future distribution under the
Plan; provided, however, that if Shares issued pursuant to Awards of Restricted Stock, Restricted Stock Units, Performance Shares or Performance Units are repurchased by the Company or are forfeited to the Company, such Shares will become available
for future grant under the Plan. Shares used to pay the exercise price of an Award or to satisfy the tax withholding obligations related to an Award will become available for future grant or sale under the Plan. To the extent an Award under the Plan
is paid out in cash rather than Shares, such cash payment will not result in reducing the number of Shares available for issuance under the Plan. Notwithstanding the foregoing and, subject to adjustment as provided in Section 14, the maximum
number of Shares that may be issued upon the exercise of Incentive Stock Options will equal the aggregate Share number stated in Section 3(a), plus, to the extent allowable under Section 422 of the Code and the Treasury Regulations

Plan.

may administer the Plan. 
 (ii)    Rule 16b-3. To the extent desirable
to qualify transactions hereunder as exempt under Rule 16b-3, the transactions contemplated hereunder will be structured to satisfy the requirements for exemption under Rule
16b-3. 
 (iii)    Other Administration. Other than as provided above,
the Plan will be administered by (A) the Board or (B) a Committee, which committee will be constituted to satisfy Applicable Laws.

to the specific duties delegated by the Board to such Committee, the Administrator will have the authority, in its discretion:

hereunder. Such terms and conditions include, but are not limited to, the exercise price, the time or times 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 thereto, based in each case on such factors as the Administrator will determine; 

(vi)    to institute and determine the terms and conditions of an Exchange Program; 

(vii)    to construe and interpret the terms of the Plan and Awards granted pursuant to the Plan; 

(viii)    to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations
relating to sub-plans established for the purpose of satisfying applicable non-U.S. laws or for qualifying for favorable tax treatment under applicable non-U.S. laws; 
 (ix)    to modify or amend each Award (subject to Section 19
of the Plan), including but not limited to the discretionary authority to extend the post-termination exercisability period of Awards and to extend the maximum term of an Option (subject to Section 6(b) of the Plan regarding Incentive
Stock Options); 
 (x)    to allow Participants to satisfy tax withholding obligations in such manner as prescribed in
Section 15 of the Plan; 
 (xi)    to authorize any person to execute on behalf of the Company any instrument
required to effect the grant of an Award previously granted by the Administrator; 
 (xii)    to allow a Participant to
defer the receipt of the payment of cash or the delivery of Shares that would otherwise be due to such Participant under an Award; and 

(xiii)    to make all other determinations deemed necessary or advisable for administering the Plan. 

(c)    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.

Performance Shares and Performance Units may be granted to Service Providers. Incentive Stock Options may be granted only to Employees. 

  
 -8- 

 6.    Stock Options. 

(a)    Limitations. Each Option will be designated in the Award Agreement as either an Incentive Stock Option or a
Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate fair market value of the shares with respect to which incentive stock options are exercisable for the first time by the Participant during any
calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds one hundred thousand dollars ($100,000), such options will be treated as nonstatutory stock options. For purposes of this Section 6(a), incentive stock
options will be taken into account in the order in which they were granted. The fair market value of the shares will be determined as of the time the option with respect to such shares is granted. 

(b)    Term of Option. The term of each Option will be stated in the Award Agreement. In the case of an Incentive
Stock Option, the term will be ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement. Moreover, in the case of an Incentive Stock Option granted to a Participant who, at the time the Incentive
Stock Option is granted, owns stock representing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or any Parent or Subsidiary, the term of the Incentive Stock Option will be five (5) years
from the date of grant or such shorter term as may be provided in the Award Agreement. 
 (c)    Option Exercise
Price and Consideration. 
 (i)    Exercise Price. The per share exercise price for the Shares to be issued
pursuant to exercise of an Option will be determined by the Administrator, subject to the following: 
 (1)    In the
case of an Incentive Stock Option 
 (A)    granted to an Employee who, at the time the Incentive Stock Option is
granted, owns stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or any Parent or Subsidiary, the per Share exercise price will be no less than one hundred ten percent (110%) of the Fair
Market Value per Share on the date of grant. 
 (B)    granted to any Employee other than an Employee described in
paragraph (A) immediately above, the per Share exercise price will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant. 

(2)    In the case of a Nonstatutory Stock Option, the per Share exercise price will be no less than one hundred percent
(100%) of the Fair Market Value per Share on the date of grant. 
 (3)    Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant pursuant to a transaction described in, and in a manner consistent with, Section 424(a) of the Code.

  
 -9- 

 (ii)    Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator will fix the period within which the Option may be exercised and will determine any conditions that must be satisfied before the Option may be exercised. 

(iii)    Form of Consideration. The Administrator will determine the acceptable form of consideration for
exercising an Option, including the method of payment. In the case of an Incentive Stock Option, the Administrator will determine the acceptable form of consideration at the time of grant. Such consideration may consist entirely of: (1) cash;
(2) check; (3) promissory note, to the extent permitted by Applicable Laws, (4) other Shares, provided that such Shares 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 and provided that accepting such Shares will not result in any adverse accounting consequences to the Company, as the Administrator determines in its sole discretion; (5) consideration received by the Company under
a broker-assisted (or other) cashless exercise program (whether through a broker or otherwise) implemented by the Company in connection with the Plan; (6) by net exercise; (7) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws; or (8) any combination of the foregoing methods of payment. 

(d)    Exercise of Option. 

(i)    Procedure for Exercise; Rights as a Stockholder. Any Option granted hereunder will be exercisable according
to the terms of the Plan and at such times and under such conditions as determined by the Administrator and set forth in the Award Agreement. An Option may not be exercised for a fraction of a Share. 

An Option will be deemed 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). Full payment may consist of any
consideration and method of payment authorized by the Administrator and permitted by the Award Agreement and the Plan. Shares issued upon exercise of an Option will be issued in the name of the Participant or, if requested by the Participant, in the
name of the Participant and his or her spouse. Until the Shares are issued (as evidenced by the appropriate 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, notwithstanding the exercise of the Option. The Company will issue (or cause to be issued) such Shares promptly after the Option is exercised. No adjustment
will be made for a dividend or other right for which the record date is prior to the date the Shares are issued, except as provided in Section 14 of the Plan. 

Exercising an Option in any manner will decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised. 
 (ii)    Termination of Relationship as a
Service Provider. If a Participant ceases to be a Service Provider, other than upon the Participant’s termination as the result of the Participant’s death or Disability, the Participant may exercise his or her Option within such period
of time as is specified in the Award Agreement to the extent that the Option is vested on the date of 

  
 -10- 

 termination (but in no event later than the expiration of the term of such Option as set forth in the Award
Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for three (3) months following the Participant’s termination. Unless otherwise provided by the Administrator, if on the date of
termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does not exercise his or her Option within the time
specified by the Administrator, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iii)    Disability of Participant. If a Participant ceases to be a Service Provider as a result of the
Participant’s Disability, the Participant may exercise his or her Option within such period of time as is specified in the Award Agreement to the extent the Option is vested on the date of termination (but in no event later than the expiration
of the term of such Option as set forth in the Award Agreement). In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following the Participant’s termination. Unless otherwise
provided by the Administrator, if on the date of termination the Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will revert to the Plan. If after termination the Participant does
not exercise his or her Option within the time specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(iv)    Death of Participant. If a Participant dies while a Service Provider, the Option may be exercised
following the Participant’s death within such period of time as is specified in the Award Agreement to the extent that the Option is vested on the date of death (but in no event may the option be exercised later than the expiration of the term
of such Option as set forth in the Award Agreement), by the Participant’s designated beneficiary, provided such beneficiary has been designated prior to Participant’s death in a form acceptable to the Administrator. If no such beneficiary
has been designated by the Participant, then such Option may be exercised by the personal representative of the Participant’s estate or by the person(s) to whom the Option is transferred pursuant to the Participant’s will or in
accordance with the laws of descent and distribution. In the absence of a specified time in the Award Agreement, the Option will remain exercisable for twelve (12) months following Participant’s death. Unless otherwise provided by the
Administrator, if at the time of death Participant is not vested as to his or her entire Option, the Shares covered by the unvested portion of the Option will immediately revert to the Plan. If the Option is not so exercised within the time
specified herein, the Option will terminate, and the Shares covered by such Option will revert to the Plan. 

(v)    Tolling Expiration. A Participant’s Award Agreement may also provide that: 

(1)    if the exercise of the Option following the termination of Participant’s status as a Service Provider (other
than upon the Participant’s death or Disability) would result in liability under Section 16(b), then the Option will terminate on the earlier of (A) the expiration of the term of the Option set forth in the Award Agreement, or
(B) the tenth (10th) day after the last date on which such exercise would result in liability under Section 16(b); or 

  
 -11- 

 (2)    if the exercise of the Option following the termination of the
Participant’s status as a Service Provider (other than upon the Participant’s death or Disability) would be prohibited at any time solely because the issuance of Shares would violate the registration requirements under the Securities Act,
then the Option will terminate on the earlier of (A) the expiration of the term of the Option or (B) the expiration of a period of thirty (30)-day period after the termination of the
Participant’s status as a Service Provider during which the exercise of the Option would not be in violation of such registration requirements. 

7.    Restricted Stock. 

(a)    Grant of Restricted Stock. Subject to the terms and provisions of the Plan, the Administrator, at any time
and from time to time, may grant Shares of Restricted Stock to Service Providers in such amounts as the Administrator, in its sole discretion, will determine. 

(b)    Restricted Stock Agreement. Each Award of Restricted Stock will be evidenced by an Award Agreement that will
specify the Period of Restriction, the number of Shares granted, and such other terms and conditions as the Administrator, in its sole discretion, will determine. Unless the Administrator determines otherwise, the Company as escrow agent will hold
Shares of Restricted Stock until the restrictions on such Shares have lapsed. 
 (c)    Transferability. Except
as provided in this Section 7 or the Award Agreement, Shares of Restricted Stock may not be sold, transferred, pledged, assigned, or otherwise alienated or hypothecated until the end of the applicable Period of Restriction. 

(d)    Other Restrictions. The Administrator, in its sole discretion, may impose such other restrictions on Shares
of Restricted Stock as it may deem advisable or appropriate. 
 (e)    Removal of Restrictions. Except as
otherwise provided in this Section 7, Shares of Restricted Stock covered by each Restricted Stock grant made under the Plan will be released from escrow as soon as practicable after the last day of the Period of Restriction or at such other
time as the Administrator may determine. The Administrator, in its discretion, may accelerate the time at which any restrictions will lapse or be removed. 

(f)    Voting Rights. During the Period of Restriction, Service Providers holding Shares of Restricted Stock
granted hereunder may exercise full voting rights with respect to those Shares, unless the Administrator determines otherwise. 

(g)    Dividends and Other Distributions. During the Period of Restriction, Service Providers holding Shares of
Restricted Stock will be entitled to receive all dividends and other distributions paid with respect to such Shares, unless the Administrator provides otherwise. If any such dividends 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. 

(h)    Return of Restricted Stock to Company. On the date set forth in the Award Agreement, the Restricted Stock
for which restrictions have not lapsed will revert to the Company and again will become available for grant under the Plan. 

  
 -12- 

 8.    Restricted Stock Units. 

(a)    Grant. Restricted Stock Units may be granted at any time and from time to time as determined by the
Administrator. After the Administrator determines that it will grant Restricted Stock Units under the Plan, it will advise the Participant in an Award Agreement of the terms, conditions, and restrictions related to the grant, including the number of
Restricted Stock Units. 
 (b)    Vesting Criteria and Other Terms. The Administrator will set vesting criteria
in its discretion, which, depending on the extent to which the criteria are met, will determine the number of Restricted Stock Units that will be paid out to the Participant. The Administrator may set vesting criteria based upon the achievement of
Company-wide, divisional, business unit, or individual goals (including, but not limited to, continued employment or service), applicable federal or state securities laws or any other basis determined by the Administrator in its discretion. 

(c)    Earning Restricted Stock Units. Upon meeting the applicable vesting criteria, the Participant will be
entitled to receive a payout as determined by the Administrator. Notwithstanding the foregoing, at any time after the grant of Restricted Stock Units, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be
met to receive a payout. 
 (d)    Form and Timing of Payment. Payment of earned Restricted Stock Units will be
made as soon as practicable after the date(s) determined by the Administrator and set forth in the Award Agreement. The Administrator, in its sole discretion, may only settle earned Restricted Stock Units in cash, Shares, or a combination of
both. 
 (e)    Cancellation. On the date set forth in the Award Agreement, all unearned Restricted Stock Units
will be forfeited to the Company. 
 9.    Stock Appreciation Rights. 

(a)    Grant of Stock Appreciation Rights. Subject to the terms and conditions of the Plan, a Stock Appreciation
Right may be granted to Service Providers at any time and from time to time as will be determined by the Administrator, in its sole discretion. 

(b)    Number of Shares. The Administrator will have complete discretion to determine the number of Stock
Appreciation Rights granted to any Service Provider. 
 (c)    Exercise Price and Other Terms. The per share
exercise price for the Shares to be issued pursuant to exercise of a Stock Appreciation Right will be determined by the Administrator and will be no less than one hundred percent (100%) of the Fair Market Value per Share on the date of grant.
Otherwise, the Administrator, subject to the provisions of the Plan, will have complete discretion to determine the terms and conditions of Stock Appreciation Rights granted under the Plan. 

(d)    Stock Appreciation Right Agreement. Each Stock Appreciation Right grant will be evidenced by an Award
Agreement that will specify the exercise price, the term of the Stock Appreciation Right, the conditions of exercise, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 

  
 -13- 

 (e)    Expiration of Stock Appreciation Rights. A Stock Appreciation
Right granted under the Plan will expire ten (10) years from the date of grant or such shorter term as may be provided in the Award Agreement, as determined by the Administrator, in its sole discretion. Notwithstanding the foregoing, the rules
of Section 6(d) relating to exercise also will apply to Stock Appreciation Rights. 
 (f)    Payment of
Stock Appreciation Right Amount. Upon exercise of a Stock Appreciation Right, a Participant will be entitled to receive payment from the Company in an amount determined by multiplying: 

(i)    The difference between the Fair Market Value of a Share on the date of exercise over the exercise price; times

 (ii)    The number of Shares with respect to which the Stock Appreciation Right is exercised. 

At the discretion of the Administrator, the payment upon Stock Appreciation Right exercise may be in cash, in Shares of equivalent value, or
in some combination thereof. 
 10.    Performance Units and Performance Shares. 

(a)    Grant of Performance Units/Shares. Performance Units and Performance Shares may be granted to Service
Providers at any time and from time to time, as will be determined by the Administrator, in its sole discretion. The Administrator will have complete discretion in determining the number of Performance Units and Performance Shares granted to each
Participant. 
 (b)    Value of Performance Units/Shares. Each Performance Unit will have an initial value that
is established by the Administrator on or before the date of grant. Each Performance Share will have an initial value equal to the Fair Market Value of a Share on the date of grant. 

(c)    Performance Objectives and Other Terms. The Administrator will set performance objectives or other vesting
provisions (including, without limitation, continued status as a Service Provider) in its discretion which, depending on the extent to which they are met, will determine the number or value of Performance Units/Shares that will be paid out to
the Service Providers. The time period during which the performance objectives or other vesting provisions must be met will be called the “Performance Period.” Each Award of Performance Units/Shares will be evidenced by an Award Agreement
that will specify the Performance Period, and such other terms and conditions as the Administrator, in its sole discretion, will determine. 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), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion. 

(d)    Earning of Performance Units/Shares. After the applicable Performance Period has ended, the holder of
Performance Units/Shares will be entitled to receive a payout of the 

  
 -14- 

 number of Performance Units/Shares earned by the Participant over the Performance Period, to be determined as a
function of the extent to which the corresponding performance objectives or other vesting provisions have been achieved. After the grant of a Performance Unit/Share, the Administrator, in its sole discretion, may reduce or waive any performance
objectives or other vesting provisions for such Performance Unit/Share. 
 (e)    Form and Timing of Payment of
Performance Units/Shares. Payment of earned Performance Units/Shares will be made as soon as practicable after the expiration of the applicable Performance Period. The Administrator, in its sole discretion, may pay earned Performance
Units/Shares in the form of cash, in Shares (which have an aggregate Fair Market Value equal to the value of the earned Performance Units/Shares at the close of the applicable Performance Period) or in a combination thereof. 

(f)    Cancellation of Performance Units/Shares. On the date set forth in the Award Agreement, all unearned or
unvested Performance Units/Shares will be forfeited to the Company, and again will be available for grant under the Plan. 

11.    Outside Director Limitations. No Outside Director may be paid, issued or granted, in any Fiscal Year, cash
compensation and equity awards (including any Awards issued under this Plan) with an aggregate value greater than $1,200,000 (with the value of each equity award based on its grant date fair value (determined in accordance with U.S. generally
accepted accounting principles)). Any cash compensation paid or Awards granted to an individual for his or her services as an Employee, or for his or her services as a Consultant (other than as an Outside Director), will not count for purposes of
the limitation under this Section 11. 
 12.    Leaves of Absence/Transfer Between Locations. Unless the
Administrator provides otherwise, vesting of Awards granted hereunder will be suspended during any unpaid leave of absence. A Participant will not cease to be an Employee in the case of (i) any leave of absence approved by the Company or
(ii) transfers between locations of the Company or between the Company, its Parent, or any Subsidiary. For purposes of Incentive Stock Options, no such leave may exceed three (3) months, unless reemployment upon expiration of such leave is
guaranteed by statute or contract. If reemployment upon expiration of a leave of absence approved by the Company is not so guaranteed, then six (6) months following the first (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. 

13.    Transferability of Awards. Unless determined otherwise by the Administrator, 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, such Award will contain such additional terms and conditions as the Administrator deems appropriate. 

14.    Adjustments; Dissolution or Liquidation; Merger or Change in Control. 

(a)    Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Shares,
other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination,
repurchase, or 

  
 -15- 

 exchange of Shares or other securities of the Company, or other change in the corporate structure of the Company
affecting the Shares occurs, the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available 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 3 of the Plan. 

(b)    Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the
Administrator will notify each Participant as soon as 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. 
 (c)    Change in Control. In the event of a merger of the Company with or into another
corporation or other entity or a Change in Control, each outstanding Award will be treated as the Administrator determines subject to the restriction in the following paragraph, including, without limitation, that each Award be assumed or an
equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. The Administrator will not be required to treat all Awards or Participants similarly in the transaction. 

In the event that the successor corporation does not assume or substitute for the Award, the Participant will fully vest in and have the right
to exercise all of his or her outstanding Options and Stock Appreciation Rights, including Shares as to which such Awards would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and,
with respect to Awards with performance-based vesting, unless specifically provided otherwise under the applicable Award Agreement, a Company policy applicable to the Participant, or other written agreement between the Participant and the
Company, all performance goals or other vesting criteria will be deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. In addition, if an Option or Stock Appreciation Right is not assumed or
substituted in the event of a Change in Control, the Administrator will notify the Participant in writing or electronically that the Option or Stock Appreciation Right will be exercisable for a period of time determined by the Administrator in its
sole discretion, and the Option or Stock Appreciation Right will terminate upon the expiration of such period. 
 For the purposes of this
subsection (c), an Award will be considered assumed if, following the Change in Control, the Award confers the right to purchase or receive, for each Share subject to the Award immediately prior to the Change in Control, the consideration (whether
stock, cash, or other securities or property) received in the Change in Control by holders of Common Stock for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the Change in Control 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 the exercise of an Option or Stock Appreciation Right or upon the payout of a Restricted Stock Unit, Performance Unit or Performance Share, 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 Change in Control. 

  
 -16- 

 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-Change in Control corporate structure will not be deemed to invalidate an otherwise valid Award assumption. 

(d)    Outside Director Awards. With respect to Awards granted to an Outside Director, in the event of a Change in
Control in which such Awards are assumed or substituted for, if on the date of or following such assumption or substitution 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 (unless such resignation is 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 which would not otherwise be vested or exercisable, all restrictions on Restricted Stock and Restricted Stock Units will lapse, and, with respect to Awards with performance-based vesting, unless
specifically provided otherwise under the applicable Award Agreement, a Company policy applicable to the Participant, or other written agreement between the Participant and the Company, all performance goals or other vesting criteria will be
deemed achieved at one hundred percent (100%) of target levels and all other terms and conditions met. 

15.    Tax. 

(a)    Withholding Requirements. Prior to the delivery of any Shares or cash pursuant to an Award (or exercise
thereof) or such earlier time as any tax withholding obligations are due, the Company will have the power and the right to deduct or withhold, or require a Participant to remit to the Company, an amount sufficient to satisfy U.S. federal,
state, or local taxes, non-U.S. taxes, or other taxes (including the Participant’s FICA obligation) required to be withheld with respect to such Award (or exercise thereof). 

(b)    Withholding Arrangements. The Administrator, in its sole discretion and pursuant to such procedures as it
may specify from time to time, may permit a Participant to satisfy such tax withholding obligation, in whole or in part by (without limitation) (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable cash or
Shares having a fair market value not in excess of the maximum statutory amount required to be withheld, or (iii) delivering to the Company already-owned Shares having a fair market value not in excess of the maximum statutory amount required
to be withheld. The fair market value of the Shares to be withheld or delivered will be determined as of the date that the taxes are required to be withheld. 

(c)    Compliance With Section 409A. Awards will be designed and operated in such a manner that
they are either exempt from the application of, or comply with, the requirements of Section 409A such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A,
except as otherwise determined in the sole discretion of the Administrator. The Plan and each Award Agreement under the Plan is intended to meet the requirements of Section 409A and will be construed and interpreted in accordance with such
intent, except as otherwise determined in the sole discretion of the Administrator. To the extent that an Award or payment, or the settlement or deferral thereof, is subject to Section 409A the 

  
 -17- 

 Award will be granted, paid, settled or deferred in a manner that will meet the requirements of
Section 409A, such that the grant, payment, settlement or deferral will not be subject to the additional tax or interest applicable under Section 409A. In no event will the Company (or any Parent or Subsidiary of the Company, as
applicable) reimburse a Participant for any taxes imposed or other costs incurred as a result of Section 409A. 

16.    No Effect on Employment or Service. Neither the Plan nor any Award will confer upon a Participant any right
with respect to continuing the Participant’s relationship as a Service Provider, nor will they interfere in any way with the Participant’s right or the right of the Company (or any Parent or Subsidiary of the Company) to terminate such
relationship at any time, with or without cause, to the extent permitted by Applicable Laws. 
 17.    Date of
Grant. The date of grant of an Award will be, for all purposes, the date on which the Administrator makes the determination granting such Award, or such other later date as is determined by the Administrator. Notice of the determination will be
provided to each Participant within a reasonable time after the date of such grant. 
 18.    Term of Plan.
Subject to Section 23 of the Plan, the Plan will become effective upon the later to occur of (i) its adoption by the Board or (ii) the business day immediately prior to the Registration Date. It will continue in effect for a
term of ten (10) years from the date adopted by the Board, unless terminated earlier under Section 19 of the Plan. 

19.    Amendment and Termination of the Plan. 

(a)    Amendment and Termination. The Administrator may at any time amend, alter, suspend or terminate the Plan.

 (b)    Stockholder Approval. The Company will obtain stockholder approval of any Plan amendment to the extent
necessary and desirable to comply with Applicable Laws. 
 (c)    Effect of Amendment or Termination. No
amendment, alteration, suspension or termination of the Plan will materially impair the rights of any Participant, unless mutually agreed otherwise between the Participant and the Administrator, which agreement must be in writing and signed by the
Participant and the Company. Termination of the Plan will not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Awards granted under the Plan prior to the date of such termination. 

20.    Conditions Upon Issuance of Shares. 

(a)    Legal Compliance. Shares will not be issued pursuant to an Award unless the exercise of such Award and the
issuance and delivery of such Shares will comply with Applicable Laws and will be further subject to the approval of counsel for the Company with respect to such compliance. 

(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 at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the
Company, such a representation is required. 

  
 -18- 

 21.    Inability to Obtain Authority. The inability of the Company to
obtain authority from any regulatory body having jurisdiction or to complete or comply with the requirements of any registration or other qualification of the Shares under any U.S. federal or state law, any
non-U.S. law, or the rules and regulations of the Securities and Exchange Commission, the stock exchange on which Shares of the same class are then listed, or any other governmental or regulatory body, which
authority, registration, qualification or rule compliance is deemed by the Company’s counsel to be necessary or advisable for the issuance and sale of any Shares hereunder, will relieve the Company of any liability in respect of the failure to
issue or sell such Shares as to which such requisite authority, registration, qualification or rule compliance will not have been obtained. 

22.    Clawback. The Administrator may specify in an Award Agreement that the Participant’s rights,
payments, and/or benefits with respect to an Award will be subject to reduction, cancellation, forfeiture, and/or recoupment upon the occurrence of certain specified events, in addition to any applicable vesting, performance or other conditions and
restrictions of an Award. Notwithstanding any provisions to the contrary under this Plan, an Award granted under the Plan shall be subject to the Company’s clawback policy as may be established and/or amended from time to time. The Board may

2018 EQUITY INCENTIVE PLAN 

IRISH APPENDIX 
 (Current
as of 3 November 2017) 
 Capitalized terms not explicitly defined in this Irish Appendix but defined in the Plan shall have the
same definitions as in the Plan, unless the context otherwise requires. 
  

	1.	Purpose and eligibility 

 The purpose of this appendix to the Plan (the “Irish
Appendix”) is to enable the Committee to grant awards, including Options, Restricted Stock Units, Stock Appreciation Rights, Restricted Stock, Performance Units or Performance Shares (the “Award” or “Awards”) to certain
employees and full-time directors of the Company and any Subsidiary who are based in Ireland. The Irish Appendix should be read and construed as one document with the Plan. Awards (which in the case of Options will be unapproved for Irish tax
purposes) may only be granted under the Irish Appendix to employees and full-time directors of the Company and any Subsidiary. Any person to whom an Award has been granted under the Irish Appendix is a “Participant” for the purposes of the
Plan. 
 The tax and social security consequences of participating in the Plan are based on complex tax and social security laws, which may
be subject to varying interpretations, and the application of such laws may depend, in large part, on the surrounding facts and circumstances. Therefore, we recommend that the Participant consults with their own tax advisor regularly to
determine the consequences of taking or not taking any action concerning their participation in the Plan and to determine how the tax, social security or other laws in Ireland (or elsewhere) apply to their specific situation. 

 

	2.	Terms 

 Awards granted pursuant to the Plan shall be governed by the terms of the Plan,
subject to any such amendments set out herein and as are necessary to give effect to Section 1 of the Irish Appendix, and by the terms of the individual Award agreement entered into between the Company and the Participant. To the extent that
there is a conflict between the rules of the Plan and the Irish Appendix, or the relevant Award agreement and Irish Appendix, the provisions of the Irish Appendix shall prevail. 

 

	3.	Taxes 

 The references in the Plan, and in particular clause 15 (Tax) of the Plan, to
“tax” or “taxes” includes any and all taxes, charges, levies and contributions in Ireland or elsewhere, to include, in particular, Universal Social Charge (USC) and Pay Related Social Insurance (PRSI) (“Taxes”).

  

	4.	Tax indemnity 

  

	4.1	The Participant shall be accountable for any Taxes, which are chargeable on any assessable income deriving from the grant, exercise, purchase, vesting of, or other dealing in Awards or Shares issued pursuant to an
Award. The Company shall not become liable for any Taxes, as a result of the Participant’s participation in the Plan. In respect of such assessable income, the Participant shall indemnify the Company and (at the direction of the Company) any
Subsidiary, which is or may be treated as the employer of the Participant in respect of the Taxes (the “Tax Liabilities”). 

  
 -20- 

	4.2	Pursuant to the indemnity referred to in Section 4.1, where necessary, the Participant shall make such arrangements, as the Company requires to meet the cost of the Tax Liabilities, including at the direction of
the Company any of the following: 

  

	 	(a)	making a cash payment of an appropriate amount to the relevant company whether by cheque, banker’s draft or deduction from salary in time to enable the Company to remit such amount to the Irish Revenue
Commissioners before the 14th day following the end of the month in which the event giving rise to the Tax Liabilities occurred; or 

  

	 	(b)	appointing the Company as agent and / or attorney for the sale of sufficient Shares, acquired pursuant to the grant, exercise, purchase, vesting or other dealing in Awards, or Shares issued pursuant to an Award to cover
the Tax Liabilities and authorising the payment to the relevant company of the appropriate amount (including all reasonable fees, commissions and expenses incurred by the relevant company in relation to such sale) out of the net proceeds of sale of
the Shares. 

  

	5.	Employment rights 

  

	5.1	The Participant acknowledges that his or her terms of employment shall not be affected in any way by his or her participation in the Plan, which shall not form part of such terms (either expressly or impliedly). The
Participant acknowledges that his or her participation in the Plan shall be subject at all times to the rules of the Plan as may be amended from time to time (including, but not limited to, any clawback provisions). If on termination of the
Participant’s employment (whether lawfully, unlawfully, or in breach of contract) he or she loses any rights or benefits under the Plan (including any rights or benefits which he or she would not have lost had his or her employment not been
terminated), the Participant hereby acknowledges that he or she shall not be entitled to (and hereby waives) any compensation for the loss of any rights or benefits under the Plan, or any replacement or successor plan. 

 

	5.2	The Plan is entirely discretionary and may be suspended or terminated by the Committee or by the Company at any time for any reason. Participation in the Plan is entirely discretionary and does not create any
contractual or other right to receive future grants of Awards or benefits in lieu of Awards. All determinations with respect to future grants will be at the sole discretion of the Committee or the Company. Rights under the Plan are not pensionable.

  

	6.	Data Protection 

  

	6.1	Section 14 of the Award Agreement does not apply.

 -23- 

 
from the end of the year in which the first grant was made in accordance with the previous Election, or as otherwise provided by Applicable Law. Any Election shall not prevent the Company from
granting 102 Non-Trustee Awards.

pursuant hereto shall supersede and be deemed to amend any date of grant indicated in any corporate resolution or Award Agreement. 

3.5.    102 Trustee Awards. 

3.5.1.    Each 102 Trustee Award, each share of Common Stock issued pursuant to the grant, exercise or vesting of any 102
Trustee Award and any rights granted thereunder, shall be allocated or issued to and registered in the name of the Trustee and shall be held in trust or controlled by the Trustee for the benefit of the Participant for the requisite period prescribed
by the Ordinance or such longer period as set by the Committee (the “Required Holding Period”). 

3.5.2.    In the event that the requirements under Section 102 to qualify an Award as a 102 Trustee Award are not
met, then the Award may be treated as a 102 Non-Trustee Award or shall be subject to tax under Section 3(i) or 2 of the Ordinance (as determined by the Company), all in accordance with the provisions of
the Ordinance. Subject to the provisions of Section 102 and the Rules, the Trustee shall not release any 102 Trustee Awards or shares of Common Stock issued in connection with a Trustee 102 Award prior to the payment in full of the
Participant’s tax and compulsory payments arising from such 102 Trustee Awards and/or shares of Common Stock. 

3.5.3.    Each 102 Trustee Award shall be subject to the relevant terms of the Ordinance, the Rules and any determinations,
rulings or approvals issued by the ITA, which shall be deemed an integral part of the 102 Trustee Awards and shall prevail over any term contained in the Plan, this Appendix or the Award Agreement that is not consistent therewith. Any provision of
the Ordinance, the Rules and any determinations, rulings or approvals by the ITA not expressly specified in the Plan, this Appendix or Award Agreement that are necessary to receive or maintain any tax benefit pursuant to Section 102 shall be
binding on the Participant. The Participant granted a 102 Trustee Award shall comply with the Ordinance and the terms and conditions of the Trust Agreement entered into between the Company and the Trustee. The Participant shall execute any and all
documents that the Company and/or the Subsidiary and/or the Trustee determine from time to time to be necessary in order to comply with the Ordinance and the Rules. 

3.5.4.    During the Required Holding Period, the Participant shall not release from trust or 

  
 -24- 

 
sell, assign, transfer or give as collateral, the shares of Common Stock issued in connection with a 102 Trustee Award and/or any securities issued or distributed with respect thereto, until the
expiration of the Required Holding Period. Notwithstanding the above, if any such sale, release or other action occurs during the Required Holding Period it may result in adverse tax consequences to the Participant under Section 102 and the
Rules, which shall apply to and shall be borne solely by such Participant. Subject to the foregoing, the Trustee may, pursuant to a written request from the Participant, but subject to the terms of the Plan and this Appendix, release and transfer
such shares of Common Stock to a designated third party, provided that both of the following conditions have been fulfilled prior to such release or transfer: (i) payment has been made to the ITA of all taxes and compulsory payments required to
be paid upon the release and transfer of the shares of Common Stock, and confirmation of such payment has been received by the Trustee and the Company, and (ii) the Trustee has received written confirmation from the Company that all
requirements for such release and transfer have been fulfilled according to the terms of the Company’s corporate documents, any agreement governing the shares of Common Stock, the Plan, this Appendix, the Award Agreement and any Applicable Law.

 3.5.5.    As a condition to the grant of a 102 Trustee Award the Participant shall sign a declaration as required in
order to comply with the provisions of Section 102 and the Rules. 
 3.6.    102
Non-Trustee Awards. The foregoing provisions of this Section 3 relating to 102 Trustee Awards shall not apply with respect to 102 Non-Trustee Awards, which
shall, however, be subject to the relevant provisions of Section 102 and the applicable Rules. The Committee may determine that 102 Non-Trustee Awards, the shares of Common Stock issuable upon the
exercise or (if applicable) vesting of a 102 Non-Trustee Award and/or any securities issued or distributed with respect thereto, shall be allocated or issued to a third party administrator , who shall hold
such 102 Non-Trustee Award and all accrued rights thereon (if any) in trust for the benefit of the Participant and/or the Company, as the case may be, until the full payment of tax arising from the 102 Non-Trustee Awards, the shares of Common Stock issuable upon the exercise or (if applicable) vesting of a 102 Non-Trustee Award and/or any securities issued or distributed
with respect thereto. The Company may choose, alternatively, to require the Participant to provide the Company with a guarantee or other security, to the satisfaction of the employing Subsidiary and the Company, until the full payment of the
applicable taxes. 
  

	4.	3(9) AWARDS 

 4.1.    This Section 4 shall apply to Awards which
are 3(9) Awards which are granted subject to the general terms and conditions of the Plan, except for any provisions of the Plan applying to Awards under different tax laws or regulations. In the event of any inconsistency or contradictions between
the provisions of this Section 4 and the other terms of the Plan, this Section 4 shall prevail. 

4.2.    Shares of Common Stock pursuant to a 3(9) Award shall not be issued upon exercise or vesting, as applicable,
unless the Participant delivers to the Company payment in cash or by bank check or such other form acceptable to the Committee of all withholding taxes due, if any, on account of the Participant acquiring shares of Common Stock under the Award or
the Participant provides other assurance satisfactory to the Committee of the payment of those withholding taxes. Alternatively the Company may sell such amount of shares of Common Stock underlying the Award as required to satisfy the tax
withholding obligations and deliver the net amount to the Participant. 
  

	5.    AGREEMENT	REGARDING TAXES; DISCLAIMER 

 5.1.    If the Committee shall so
require, as a condition of exercise of an Award or the release of shares of Common Stock by the Trustee, a Participant shall agree that, no later than the date of such occurrence, the Participant will pay to the Company (or the Trustee, as
applicable) or make arrangements satisfactory to the Committee and the Trustee (if applicable) regarding payment of any applicable taxes and compulsory payments of any kind required by Applicable Law to be withheld or paid. 

  
 -25- 

 5.2.    TAX LIABILITY. ALL TAX CONSEQUENCES UNDER ANY APPLICABLE LAW
WHICH MAY ARISE FROM THE GRANT OF ANY AWARDS OR THE EXERCISE OR VESTING THEREOF, THE SALE OR DISPOSITION OF ANY SHARES OF COMMON STOCK GRANTED HEREUNDER OR ISSUED UPON EXERCISE OR (IF APPLICABLE) VESTING OF ANY AWARD, THE ASSUMPTION, SUBSTITUTION,
CANCELLATION OR PAYMENT IN LIEU OF AWARDS OR FROM ANY OTHER ACTION IN CONNECTION WITH THE FOREGOING (INCLUDING WITHOUT LIMITATION ANY TAXES AND COMPULSORY PAYMENTS, SUCH AS SOCIAL SECURITY OR HEALTH TAX PAYABLE BY THE PARTICIPANT OR THE COMPANY IN
CONNECTION THEREWITH) SHALL BE BORNE AND PAID SOLELY BY THE PARTICIPANT, AND THE PARTICIPANT SHALL INDEMNIFY THE COMPANY, THE SUBSIDIARY AND THE TRUSTEE, AND SHALL HOLD THEM HARMLESS AGAINST AND FROM ANY LIABILITY FOR ANY SUCH TAX OR PAYMENT OR ANY
PENALTY, INTEREST OR INDEXATION THEREON. EACH PARTICIPANT AGREES TO, AND UNDERTAKES TO COMPLY WITH, ANY RULING, SETTLEMENT, CLOSING AGREEMENT OR OTHER SIMILAR AGREEMENT OR ARRANGEMENT WITH ANY TAX AUTHORITY IN CONNECTION WITH THE FOREGOING WHICH IS
APPROVED BY THE COMPANY. 
 5.3.    NO TAX ADVICE. THE PARTICIPANT IS ADVISED TO CONSULT WITH A TAX ADVISOR WITH
RESPECT TO THE TAX CONSEQUENCES OF RECEIVING, EXERCISING OR DISPOSING OF AWARDS HEREUNDER. THE COMPANY DOES NOT ASSUME ANY RESPONSIBILITY TO ADVISE THE PARTICIPANT ON SUCH MATTERS, WHICH SHALL REMAIN SOLELY THE RESPONSIBILITY OF THE PARTICIPANT.

 5.4.    TAX TREATMENT. THE COMPANY DOES NOT UNDERTAKE OR ASSUME ANY LIABILITY OR RESPONSIBILITY TO THE EFFECT
THAT ANY AWARD SHALL QUALIFY WITH ANY PARTICULAR TAX REGIME OR RULES APPLYING TO PARTICULAR TAX TREATMENT, OR BENEFIT FROM ANY PARTICULAR TAX TREATMENT OR TAX ADVANTAGE OF ANY TYPE AND THE COMPANY SHALL BEAR NO LIABILITY IN CONNECTION WITH THE
MANNER IN WHICH ANY AWARD IS EVENTUALLY TREATED FOR TAX PURPOSES, REGARDLESS OF WHETHER THE AWARD WAS GRANTED OR WAS INTENDED TO QUALIFY UNDER ANY PARTICULAR TAX REGIME OR TREATMENT. THIS PROVISION SHALL SUPERSEDE ANY DESIGNATION OF AWARDS OR TAX
QUALIFICATION INDICATED IN ANY CORPORATE RESOLUTION OR AWARD AGREEMENT, WHICH SHALL AT ALL TIMES BE SUBJECT TO THE REQUIREMENTS OF APPLICABLE LAW. THE COMPANY DOES NOT UNDERTAKE AND SHALL NOT BE REQUIRED TO TAKE ANY ACTION IN ORDER TO QUALIFY ANY
AWARD WITH THE REQUIREMENTS OF ANY PARTICULAR TAX TREATMENT AND NO INDICATION IN ANY DOCUMENT TO THE EFFECT THAT ANY AWARD IS INTENDED TO QUALIFY FOR ANY TAX TREATMENT SHALL IMPLY SUCH AN UNDERTAKING. NO ASSURANCE IS MADE BY THE COMPANY OR THE
SUBSIDIARY THAT ANY PARTICULAR TAX TREATMENT ON THE DATE OF GRANT WILL CONTINUE TO EXIST OR THAT THE AWARD WILL QUALIFY AT THE TIME OF EXERCISE OR DISPOSITION THEREOF WITH ANY PARTICULAR TAX TREATMENT. THE COMPANY AND THE SUBSIDIARY SHALL NOT HAVE
ANY LIABILITY OR OBLIGATION OF ANY NATURE IN THE EVENT THAT AN AWARD DOES NOT QUALIFY FOR ANY PARTICULAR TAX TREATMENT, REGARDLESS WHETHER THE COMPANY COULD HAVE TAKEN ANY ACTION TO CAUSE SUCH QUALIFICATION TO BE MET AND SUCH QUALIFICATION REMAINS
AT ALL TIMES AND UNDER ALL CIRCUMSTANCES AT THE RISK OF THE PARTICIPANT. THE COMPANY DOES NOT UNDERTAKE OR ASSUME ANY LIABILITY TO CONTEST A DETERMINATION OR INTERPRETATION (WHETHER WRITTEN OR UNWRITTEN) OF ANY TAX 

  
 -26- 

 
AUTHORITY, INCLUDING IN RESPECT OF THE QUALIFICATION UNDER ANY PARTICULAR TAX REGIME OR RULES APPLYING TO PARTICULAR TAX TREATMENT. IF THE AWARDS DO NOT QUALIFY UNDER ANY PARTICULAR TAX TREATMENT
IT COULD RESULT IN ADVERSE TAX CONSEQUENCES TO THE PARTICIPANT. 
 5.5.    The Company or the Subsidiary may take such
action as it may deem necessary or appropriate, in its discretion, for the purpose of or in connection with withholding of any taxes and compulsory payments which the Trustee, the Company or the Subsidiary is required by any Applicable Law to
withhold in connection with any Awards (collectively, “Withholding Obligations”). Such actions may include (i) requiring Participants to remit to the Company in cash an amount sufficient to satisfy such Withholding Obligations
and any other taxes and compulsory payments, payable by the Company in connection with the Award or the exercise or (if applicable) vesting thereof; (ii) subject to Applicable Law, allowing the Participants to provide shares of Common Stock, in
an amount that at such time, reflects a value that the Committee determines to be sufficient to satisfy such Withholding Obligations; (iii) withholding shares of Common Stock otherwise issuable upon the exercise of an Award at a value which is
determined by the Committee to be sufficient to satisfy such Withholding Obligations; or (iv) any combination of the foregoing. The Company shall not be obligated to allow the exercise of any Award by or on behalf of a Participant until all tax
consequences arising from the exercise of such Award are resolved in a manner acceptable to the Company. 
 5.6.    Each
Participant shall notify the Company in writing promptly and in any event within ten (10) days after the date on which such Participant first obtains knowledge of any tax bureau inquiry, audit, assertion, determination, investigation, or
question relating in any manner to the Awards granted or received hereunder or shares of Common Stock issued thereunder and shall continuously inform the Company of any developments, proceedings, discussions and negotiations relating to such matter,
and shall allow the Company and its representatives to participate in any proceedings and discussions concerning such matters. Upon request, a Participant shall provide to the Company any information or document relating to any matter described in
the preceding sentence, which the Company, in its discretion, requires. 
 5.7.    With respect to 102 Non-Trustee Awards, if the Participant ceases to be employed by the Company or any Subsidiary, the Participant shall extend to the Company and/or the Subsidiary with whom the Participant is employed a security or
guarantee for the payment of taxes due at the time of sale of shares of Common Stock, all in accordance with the provisions of Section 102 and the Rules. 

6.    ASSIGNABILITY, DESIGNATION AND SALE OF AWARDS 

6.1.    Despite any other provision of the Plan (including section 6(d)(i) of the Plan), no 102 Award or any right with
respect thereto, or purchasable hereunder, whether fully paid or not, shall be assignable, transferable or given as collateral, or any right with respect to any 102 Award given to any third party whatsoever, and during the lifetime of the Israeli
Employee, each and all of such Israeli Employee’s rights with respect to a Grant shall belong only to the Israeli Employee. Any such action made directly or indirectly, for an immediate or future validation, shall be void. 

6.2.    As long as 102 Awards or Common Stock issued or purchased hereunder are held by the Trustee on behalf of the
Israeli Employee, all rights of the Israeli Employee t over the Common Stock cannot be transferred, assigned, pledged or mortgaged, other than by will or laws of descent and distribution. 

7.    ONE TIME AWARD 

7.1.    The 102 Awards and underlying Common Stock are extraordinary, one-time
awards granted to the Israeli Employees, and are not and shall not be deemed a salary component for any purpose whatsoever, including in connection with calculating severance compensation under applicable law, nor shall receipt of an award entitle
an Israeli Employee to any future Award. 

  
 -27- 

 8.    GOVERNING LAW 

8.1.    This Appendix shall be governed by, construed and enforced in accordance with the laws of the State of California,
without reference to conflicts of law principles, except that applicable Israeli laws, rules and regulations (as amended) shall apply to any mandatory tax matters arising hereunder.

Notice of Stock Option Grant of this Option Agreement (the “Notice of Grant”) an option (the “Option”) to purchase the number of Shares, as set forth in the Notice of Grant, at the exercise price per Share set forth in the Notice
of Grant (the “Exercise Price”), subject to all of the terms and conditions in this Option Agreement and the Plan, which is incorporated herein by reference. Subject to Section 19(c) of the Plan, in the event of a conflict between the
terms and conditions of the Plan and the terms and conditions of this Option Agreement, the terms and conditions of the Plan will prevail. 

(a)    For U.S. taxpayers, the Option will be designated as either an Incentive Stock Option (“ISO”) or a
Nonstatutory Stock Option (“NSO”). If designated in the Notice of Grant as an ISO, this Option is intended to qualify as an ISO under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). However, if
this Option is intended to be an ISO, to the extent that it exceeds the $100,000 rule of Code Section 422(d) it will be treated as an NSO. Further, if for any reason this Option (or portion thereof) will not qualify as an ISO, then, to the
extent of such nonqualification, such Option (or portion thereof) shall be regarded as a NSO granted under the Plan. In no event will the Administrator, the Company or any Parent or Subsidiary or any of their respective employees or directors have
any liability to Participant (or any other person) due to the failure of the Option to qualify for any reason as an ISO. 

(b)    For non-U.S. taxpayers, the Option will be designated as an NSO. 

2.    Vesting Schedule. Except as provided in Section 3, the Option awarded by this Option Agreement will vest
in accordance with the vesting provisions set forth in the Notice of Grant. Shares scheduled to vest on a certain date or upon the occurrence of a certain condition will not vest in Participant in accordance with any of the provisions of this Option
Agreement, unless Participant will have been continuously a Service Provider from the Date of Grant until the date such vesting occurs. 

3.    Administrator Discretion. The Administrator, in its discretion, may accelerate the vesting of the balance, or
some lesser portion of the balance, of the unvested Option at any time, subject to the terms of the Plan. If so accelerated, such Option will be considered as having vested as of the date specified by the Administrator. 

4.    Exercise of Option. 

(a)    Right to Exercise. This Option may be exercised only within the term set out in the Notice of Grant, and may
be exercised during such term only in accordance with the Plan and the terms of this Option Agreement. 

  
 - 1 - 

 (b)    Method of Exercise. This Option is exercisable by delivery of
an exercise notice (the “Exercise Notice”) in the form attached as Exhibit A or in a manner and pursuant to such procedures as the Administrator may determine, which will state the election to exercise the Option, the number of
Shares in respect of which the Option is being exercised (the “Exercised Shares”), and such other representations and agreements as may be required by the Company pursuant to the provisions of the Plan. The Exercise Notice will be
completed by Participant and delivered to the Company. The Exercise Notice will be accompanied by payment of the aggregate Exercise Price as to all Exercised Shares together and of any Tax Obligations (as defined in Section 6(a)). This Option
will be deemed to be exercised upon receipt by the Company of such fully executed Exercise Notice accompanied by the aggregate Exercise Price. 

5.    Method of Payment. Payment of the aggregate Exercise Price will be by any of the following, or a combination
thereof, at the election of Participant: 
 (a)    cash; 

(b)    check; 

(c)    consideration received by the Company under a formal cashless exercise program adopted by the Company in connection
with the Plan; or 
 (d)    if Participant is a U.S. employee, surrender of other Shares which have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised Shares and that are owned free and clear of any liens, claims, encumbrances, or security interests, provided that accepting such Shares, in the sole discretion of the
Administrator, will not result in any adverse accounting consequences to the Company. 
 6.    Tax Obligations.

 (a)    Participant acknowledges that, regardless of any action taken by the Company or, if different,
Participant’s employer (the “Employer”) or Parent or Subsidiary to which Participant is providing services (together, the Company, Employer and/or Parent or Subsidiary to which the Participant is providing services, the “Service
Recipient”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Option, including, without limitation, (i) all federal, state, and local taxes (including the
Participant’s Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or the Service Recipient or other payment of tax-related items related to
Participant’s participation in the Plan and legally applicable to Participant, (ii) the Participant’s and, to the extent required by the Company (or Service Recipient), the Company’s (or Service Recipient’s) fringe benefit
tax liability, if any, associated with the grant, vesting, or exercise of the Option or sale of Shares, and (iii) any other Company (or Service Recipient) taxes the responsibility for which the Participant has, or has agreed to bear, with
respect to the Option (or exercise thereof or issuance of Shares thereunder) (collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually withheld by the Company or the Service
Recipient. Participant further acknowledges that the Company and/or the Service Recipient (A) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any aspect of the

  
 - 2 - 

 
Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of Shares acquired pursuant to such exercise and the receipt of any dividends or other
distributions, and (B) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate Participant’s liability for Tax Obligations or achieve any particular tax result.
Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Service
Recipient (or former employer, as applicable) may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required Tax Obligations hereunder
at the time of the applicable taxable event, Participant acknowledges and agrees that the Company may refuse to issue or deliver the Shares. 

(b)    Tax Withholding. When the Option is exercised, Participant generally will recognize immediate U.S. taxable
income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. Pursuant to such procedures as the Administrator may
specify from time to time, the Company and/or Service Recipient shall withhold the amount required to be withheld for the payment of Tax Obligations. The Administrator, in its sole discretion and pursuant to such procedures as it may specify from
time to time, may permit Participant to satisfy such Tax Obligations, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying cash, (ii) electing to have the Company withhold otherwise deliverable
Shares having a fair market value equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or such greater amount as Participant may elect if permitted by the Administrator, if such greater amount
would not result in adverse financial accounting consequences), (iii) withholding the amount of such Tax Obligations from Participant’s wages or other cash compensation paid to Participant by the Company and/or the Service Recipient,
(iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax Obligations, or (v) selling a sufficient number of such Shares otherwise deliverable to Participant through such means as the
Company may determine in its sole discretion (whether through a broker or otherwise) equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or such greater amount as Participant may elect if
permitted by the Administrator, if such greater amount would not result in adverse financial accounting consequences). To the extent determined appropriate by the Company in its discretion, it will have the right (but not the obligation) to satisfy
any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant. Further, if Participant is subject to tax in more than one jurisdiction between the Date of Grant and a date of any relevant taxable or tax withholding event,
as applicable, Participant acknowledges and agrees that the Company and/or the Service Recipient (and/or former employer, as applicable) may be required to withhold or account for tax in more than one jurisdiction. If Participant fails to make
satisfactory arrangements for the payment of any required Tax Obligations hereunder at the time of the Option exercise, Participant acknowledges and agrees that the Company may refuse to honor the exercise and refuse to deliver the Shares if such
amounts are not delivered at the time of exercise. 
 (c)    Notice of Disqualifying Disposition of ISO Shares.
If the Option granted to Participant herein is an ISO, and if Participant sells or otherwise disposes of any of the Shares acquired pursuant to the ISO on or before the later of (i) the date two (2) years after the Date of Grant, or
(ii) the date one (1) year after the date of exercise, Participant will immediately notify the Company in writing of such disposition. Participant agrees that Participant may be subject to income tax withholding by the Company on the
compensation income recognized by Participant. 

  
 - 3 - 

 (d)    Code Section 409A. Under Code
Section 409A, a stock right (such as the Option) that vests after December 31, 2004 (or that vested on or prior to such date but which was materially modified after October 3, 2004) that was granted with a per share exercise price
that is determined by the Internal Revenue Service (the “IRS”) to be less than the fair market value of an underlying share on the date of grant (a “discount option”) may be considered “deferred compensation.” A stock
right that is a “discount option” may result in (i) income recognition by the recipient of the stock right prior to the exercise of the stock right, (ii) an additional twenty percent (20%) federal income tax, and
(iii) potential penalty and interest charges. The “discount option” may also result in additional state income, penalty and interest tax to the recipient of the stock right. Participant acknowledges that the Company cannot and has not
guaranteed that the IRS will agree that the per Share exercise price of this Option equals or exceeds the fair market value of a Share on the date of grant in a later examination. Participant agrees that if the IRS determines that the Option was
granted with a per Share exercise price that was less than the fair market value of a Share on the date of grant, Participant shall be solely responsible for Participant’s costs related to such a determination. 

7.    Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any
of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the
Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation, and delivery, Participant will have all the rights of a stockholder of the
Company with respect to voting such Shares and receipt of dividends and distributions on such Shares. 
 8.    No
Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER, WHICH UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW IS AT
THE WILL OF THE COMPANY (OR THE SERVICE RECIPIENT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS OPTION AGREEMENT, THE TRANSACTIONS CONTEMPLATED
HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND WILL NOT INTERFERE IN ANY WAY WITH
PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE SERVICE RECIPIENT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE UNDER APPLICABLE LAW, MAY BE
AT ANY TIME, WITH OR WITHOUT CAUSE. 

  
 - 4 - 

 9.    Nature of Grant. In accepting the Option, Participant
acknowledges, understands and agrees that: 
 (a)    the grant of the 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; 

(b)    all decisions with respect to future option or other grants, if any, will be at the sole discretion of the Company;

 (c)    Participant is voluntarily participating in the Plan; 

(d)    the Option and any Shares acquired under the Plan are not intended to replace any pension rights or compensation;

 (e)    the Option and Shares acquired under the Plan and the income and value of same, are not part of normal or
expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal, end-of-service payments, bonuses, long-service awards,
pension or retirement or welfare benefits or similar payments; 
 (f)    the future value of the Shares underlying the
Option is unknown, indeterminable, and cannot be predicted with certainty; 
 (g)    if the underlying Shares do not
increase in value, the Option will have no value; 
 (h)    if Participant exercises the Option and acquires Shares, the
value of such Shares may increase or decrease in value, even below the Exercise Price; 
 (i)    for purposes of the
Option, Participant’s engagement as a Service Provider will be considered terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination
and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly
provided in this Option Agreement (including by reference in the Notice of Grant to other arrangements or contracts) or determined by the Administrator, (i) Participant’s right to vest in the Option under the Plan, if any, will terminate
as of such date and will not be extended by any notice period (e.g., Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment
laws in the jurisdiction where Participant is a Service Provider or Participant’s employment or service agreement, if any, unless Participant is providing bona fide services during such time); and (ii) the period (if any) during which
Participant may exercise the Option after such termination of Participant’s engagement as a Service Provider will commence on the date Participant ceases to actively provide services and will not be extended by any notice period mandated under
employment laws in the jurisdiction where Participant is employed or terms of Participant’s engagement agreement, if any; the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing
services for purposes of his or her Option grant (including whether Participant may still be considered to be providing services while on a leave of absence and consistent with local law); 

  
 - 5 - 

 (j)    unless otherwise provided in the Plan or by the Company in its
discretion, the Option and the benefits evidenced by this Option Agreement do not create any entitlement to have the Option or any such benefits transferred to, or assumed by, another company nor to be exchanged, cashed out or substituted for, in
connection with any corporate transaction affecting the Shares; and 
 (k)    the following provisions apply only if
Participant is providing services outside the United States: 
 the Option and the Shares subject to the Option are not part of normal or
expected compensation or salary for any purpose; 
 Participant acknowledges and agrees that none of the Company, the Service Recipient, or
any Parent or Subsidiary shall be liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Option or of any amounts due to Participant pursuant to the
exercise of the Option or the subsequent sale of any Shares acquired upon exercise; and 
 no claim or entitlement to compensation or
damages shall arise from forfeiture of the Option resulting from the termination of Participant’s engagement 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 Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of the Option to which Participant is otherwise not entitled, Participant irrevocably
agrees never to institute any claim against the Company, any Parent, any Subsidiary or the Service Recipient, waives his or her ability, if any, to bring any such claim, and releases the Company, any Parent or Subsidiary and the Service Recipient
from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed irrevocably to have agreed not to pursue such claim and agrees to
execute any and all documents necessary to request dismissal or withdrawal of such claim. 
 10.    No Advice
Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying
Shares. Participant is hereby advised to consult with his or her own personal tax, legal and financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

  
 - 6 - 

 11.    Data Privacy. Participant hereby explicitly
and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Option Agreement and any other Option grant materials by and among, as applicable, the Employer or
other Service Recipient, the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

Participant understands that the Company and the Employer may hold certain personal information about Participant, including, but not
limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or directorships held in the Company, details of all Options or
any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan. 

Participant understands that Data will be transferred to a stock plan service provider as may be selected by the Company in the future,
which is assisting the Company with the implementation, administration, and management of the Plan. Participant understands that the recipients of the Data may be located in the United States or elsewhere, and that the recipient’s country of
operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside the United States, he or she may request a list with the names and
addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company and any other possible recipients which may assist the Company (presently or in the future) with
implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other form, for the sole purposes of implementing, administering and managing Participant’s participation in the Plan.
Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s participation in the Plan. Participant understands that if he or she resides outside the United States, he or she may,
at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local
human resources representative. Further, Participant understands that he or she is providing the consents herein on a purely voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her
engagement as a Service Provider and career with the Employer will not be adversely affected; the only adverse consequence of refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant Options or
other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the consequences
of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may contact his or her local human resources representative. 

12.    Address for Notices. Any notice to be given to the Company under the terms of this Option Agreement will be
addressed to the Company at Dropbox, Inc., 333 Brannan Street, San Francisco, CA 94107, or at such other address as the Company may hereafter designate in writing. 

  
 - 7 - 

 13.    Non-Transferability of
Option. This Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Participant only by Participant. 

14.    Successors and Assigns. The Company may assign any of its rights under this Option Agreement to single or
multiple assignees, and this Option Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Option Agreement shall be binding upon Participant and his or her
heirs, executors, administrators, successors and assigns. The rights and obligations of Participant under this Option Agreement may only be assigned with the prior written consent of the Company. 

15.    Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion,
that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or non-U.S. law, the tax code and related regulations or under the
rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange Commission or any other governmental
regulatory authority is necessary or desirable as a condition to the purchase by, or issuance of Shares, to Participant (or his or her estate) hereunder, such purchase or issuance will not occur unless and until such listing, registration,
qualification, rule compliance, clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Subject to the terms of the Option Agreement and the Plan, the Company shall not be
required to issue any certificate or certificates for Shares hereunder prior to the lapse of such reasonable period of time following the date of exercise of the Option as the Administrator may establish from time to time for reasons of
administrative convenience. 
 16.    Language. If Participant has received this Option Agreement or any other
document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control. 

17.    Interpretation. The Administrator will have the power to interpret the Plan and this Option Agreement and to
adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Shares subject to the
Option have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any
person acting on behalf of the Administrator will be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Option Agreement. 

18.    Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents
related to the Option awarded under the Plan or future options that may be awarded under the Plan by electronic means or request Participant’s consent to participate in 

  
 - 8 - 

 
the Plan by electronic means. Participant hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through any
on-line or electronic system established and maintained by the Company or a third party designated by the Company. 

19.    Captions. Captions provided herein are for convenience only and are not to serve as a basis for
interpretation or construction of this Option Agreement. 
 20.    Agreement Severable. In the event that any
provision in this Option Agreement will be held invalid or unenforceable, such provision will be severable from, and such invalidity or unenforceability will not be construed to have any effect on, the remaining provisions of this Option Agreement.

 21.    Amendment, Suspension or Termination of the Plan. By accepting this Option, Participant expressly
warrants that he or she has received an Option under the Plan, and has received, read, and understood a description of the Plan. Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the
Company at any time. 
 22.    Governing Law and Venue. This Option Agreement will be governed by the laws of
California, without giving effect to the conflict of law principles thereof. For purposes of litigating any dispute that arises under this Option or this Option Agreement, the parties hereby submit to and consent to the jurisdiction of the State of
California, and agree that such litigation will be conducted in the courts of San Francisco County, California, or the federal courts for the United States for the Northern District of California, and no other courts, where this Option is made
and/or to be performed. 
 23.    Country Addendum. Notwithstanding any provisions in this Option Agreement, this
Option shall be subject to any special terms and conditions set forth in the appendix (if any) to this Option Agreement for Participant’s country (the “Country Addendum”). Moreover, if Participant relocates to one of the countries
included in the Country Addendum (if any), the special terms and conditions for such country will apply to Participant, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or
administrative reasons. The Country Addendum constitutes part of this Option Agreement. 
 24.    Modifications to
the Agreement. This Option Agreement constitutes the entire understanding of the parties on the subjects covered. Participant expressly warrants that he or she is not accepting this Option Agreement in reliance on any promises, representations,
or inducements other than those contained herein. Modifications to this Option Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in
the Plan or this Option Agreement, the Company reserves the right to revise this Option Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Code Section 409A or to
otherwise avoid imposition of any additional tax or income recognition under Section 409A of the Code in connection with the Option. 

25.    No Waiver. Either party’s failure to enforce any provision or provisions of this Option Agreement shall
not in any way be construed as a waiver of any such provision or provisions, 

  
 - 9 - 

 
nor prevent that party from thereafter enforcing each and every other provision of this Option Agreement. The rights granted both parties herein are cumulative and shall not constitute a waiver
of either party’s right to assert all other legal remedies available to it under the circumstances. 

26.    Tax Consequences. Participant has reviewed with its own tax advisors the U.S. federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Option Agreement. With respect to such matters, Participant relies solely on such advisors and not on any statements or
representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of this investment or the
transactions contemplated by this Option Agreement.

STOCK OPTION AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the Option granted to Participant under the Plan if
Participant works in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if Participant relocates to
another country after receiving the Option, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan, and/or the Stock Option Agreement to
which this Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of             . Such
laws are often complex and change frequently. As a result, the Company strongly recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan
because the information may be outdated when Participant exercises the Option or sells Shares acquired under the Plan. 
 In addition, the notifications are
general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as to
how the relevant laws in Participant’s country may apply to Participant’s situation. 
 Finally, if Participant is a citizen or resident of a
country other than the one in which Participant is currently working (or is considered as such for local law purposes) or if Participant moves to another country after the Option is granted, the information contained herein may not be applicable to
Participant.

 EXHIBIT A 

TERMS AND CONDITIONS OF RESTRICTED STOCK UNIT GRANT 

1.    Grant of Restricted Stock Units. The Company hereby grants to the individual (the “Participant”)
named in the Notice of Grant of Restricted Stock Units of this Award Agreement (the “Notice of Grant”) under the Plan an Award of Restricted Stock Units, subject to all of the terms and conditions in this Award Agreement and the Plan,
which is incorporated herein by reference. Subject to Section 19(c) of the Plan, in the event of a conflict between the terms and conditions of the Plan and this Award Agreement, the terms and conditions of the Plan shall prevail. 

2.    Company’s Obligation to Pay. Each Restricted Stock Unit represents the right to receive a Share on the
date it vests. Unless and until the Restricted Stock Units will have vested in the manner set forth in Section 3 or 4, Participant will have no right to payment of any such Restricted Stock Units. Prior to actual payment of any vested
Restricted Stock Units, such Restricted Stock Unit will represent an unsecured obligation of the Company, payable (if at all) only from the general assets of the Company. 

3.    Vesting Schedule. Except as provided in Section 4, and subject to Section 5, the Restricted Stock
Units awarded by this Award Agreement will vest in accordance with the vesting schedule set forth in the Notice of Grant, subject to Participant continuing to be a Service Provider through each applicable vesting date. 

4.    Payment after Vesting. 

(a)    General Rule. Subject to Section 8, any Restricted Stock Units that vest will be paid to Participant
(or in the event of Participant’s death, to his or her properly designated beneficiary or estate) in whole Shares. Subject to the provisions of Section 4(b), such vested Restricted Stock Units shall be paid in whole Shares as soon as
practicable after vesting, but in each such case within sixty (60) days following the vesting date. In no event will Participant be permitted, directly or indirectly, to specify the taxable year of payment of any Restricted Stock Units payable
under this Award Agreement. 
 (b)    Acceleration. 

(i)    Discretionary Acceleration. The Administrator, in its discretion, may accelerate the vesting of the
balance, or some lesser portion of the balance, of the unvested Restricted Stock Units at any time, subject to the terms of the Plan. If so accelerated, such Restricted Stock Units will be considered as having vested as of the date specified by the
Administrator. If Participant is a U.S. taxpayer, the payment of Shares vesting pursuant to this Section 4(b) shall in all cases be paid at a time or in a manner that is exempt from, or complies with, Section 409A. The prior sentence may
be superseded in a future agreement or amendment to this Award Agreement only by direct and specific reference to such sentence. 

(ii)    Notwithstanding anything in the Plan or this Award Agreement or any other agreement (whether entered into before,
on or after the Date of Grant), if the vesting of the balance, or some lesser portion of the balance, of the Restricted Stock Units is accelerated in 

 
connection with Participant’s termination as a Service Provider (provided that such termination is a “separation from service” within the meaning of Section 409A, as
determined by the Company), other than due to Participant’s death, and if (x) Participant is a U.S. taxpayer and a “specified employee” within the meaning of Section 409A at the time of such termination as a Service Provider
and (y) the payment of such accelerated Restricted Stock Units will result in the imposition of additional tax under Section 409A if paid to Participant on or within the six (6) month period following Participant’s termination as
a Service Provider, then the payment of such accelerated Restricted Stock Units will not be made until the date six (6) months and one (1) day following the date of Participant’s termination as a Service Provider, unless Participant
dies following his or her termination as a Service Provider, in which case, the Restricted Stock Units will be paid in Shares to Participant’s estate as soon as practicable following his or her death. 

(c)    Section 409A. It is the intent of this Award Agreement that it and all payments and benefits to U.S.
taxpayers hereunder be exempt from, or comply with, the requirements of Section 409A so that none of the Restricted Stock Units provided under this Award Agreement or Shares issuable thereunder will be subject to the additional tax imposed
under Section 409A, and any ambiguities herein will be interpreted to be so exempt or so comply. Each payment payable under this Award Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2). However, in no event will the Company reimburse Participant, or be otherwise responsible for, any taxes or costs that may be imposed on Participant as a result of Section 409A. For
purposes of this Award Agreement, “Section 409A” means Section 409A of the Code, and any final Treasury Regulations and Internal Revenue Service guidance thereunder, as each may be amended from time to time. 

5.    Forfeiture Upon Termination as a Service Provider. Notwithstanding any contrary provision of this Award
Agreement, if Participant ceases to be a Service Provider for any or no reason, the then-unvested Restricted Stock Units awarded by this Award Agreement will thereupon be forfeited at no cost to the Company and Participant will have no further
rights thereunder. 
 6.    Tax Consequences. Participant has reviewed with his or her own tax advisors the U.S.
federal, state, local and non-U.S. tax consequences of this investment and the transactions contemplated by this Award Agreement. With respect to such matters, Participant relies solely on such advisors and
not on any statements or representations of the Company or any of its agents, written or oral. Participant understands that Participant (and not the Company) shall be responsible for Participant’s own tax liability that may arise as a result of
this investment or the transactions contemplated by this Award Agreement. 
 7.    Death of Participant. Any
distribution or delivery to be made to Participant under this Award Agreement will, if Participant is then deceased, be made to Participant’s designated beneficiary, or if no beneficiary survives Participant, the administrator or executor of
Participant’s estate. 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 pertaining to said transfer. 

  
 -2- 

 8.    Tax Obligations 

(a)    Responsibility for Taxes. Participant acknowledges that, regardless of any action taken by the Company or,
if different, Participant’s employer (the “Employer”) or Parent or Subsidiary to which Participant is providing services (together, the Company, Employer and/or Parent or Subsidiary to which the Participant is providing services, the
“Service Recipient”), the ultimate liability for any tax and/or social insurance liability obligations and requirements in connection with the Restricted Stock Units, including, without limitation, (i) all federal, state, and local
taxes (including the Participant’s Federal Insurance Contributions Act (FICA) obligation) that are required to be withheld by the Company or the Employer or other payment of tax-related items related to
Participant’s participation in the Plan and legally applicable to Participant, (ii) the Participant’s and, to the extent required by the Company (or Service Recipient), the Company’s (or Service Recipient’s) fringe benefit
tax liability, if any, associated with the grant, vesting, or settlement of the Restricted Stock Units or sale of Shares, and (iii) any other Company (or Service Recipient) taxes the responsibility for which the Participant has, or has agreed
to bear, with respect to the Restricted Stock Units (or settlement thereof or issuance of Shares thereunder) (collectively, the “Tax Obligations”), is and remains Participant’s responsibility and may exceed the amount actually
withheld by the Company or the Service Recipient. Participant further acknowledges that the Company and/or the Service Recipient (A) make no representations or undertakings regarding the treatment of any Tax Obligations in connection with any
aspect of the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of Shares acquired pursuant to such settlement and the receipt of any dividends or other
distributions, and (B) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate Participant’s liability for Tax Obligations or achieve any
particular tax result. Further, if Participant is subject to Tax Obligations in more than one jurisdiction between the Date of Grant and the date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges that the
Company and/or the Service Recipient (or former employer, as applicable) may be required to withhold or account for Tax Obligations in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of any required
Tax Obligations hereunder at the time of the applicable taxable event, Participant acknowledges and agrees that the Company may refuse to issue or deliver the Shares. 

(b)    Tax Withholding. When Shares are issued as payment for vested Restricted Stock Units, Participant generally
will recognize immediate U.S. taxable income if Participant is a U.S. taxpayer. If Participant is a non-U.S. taxpayer, Participant will be subject to applicable taxes in his or her jurisdiction. Pursuant to
such procedures as the Administrator may specify from time to time, the Company and/or Service Recipient shall withhold the amount required to be withheld for the payment of Tax Obligations. The Administrator, in its sole discretion and pursuant to
such procedures as it may specify from time to time, may permit Participant to satisfy such Tax Obligations, in whole or in part (without limitation), if permissible by applicable local law, by (i) paying cash, (ii) electing to have the
Company withhold otherwise deliverable Shares having a fair market value equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or such greater amount as Participant may elect if permitted by the
Administrator, if such greater amount would not result in adverse financial accounting consequences), (iii) withholding the amount of such Tax Obligations from Participant’s wages or other cash compensation paid to Participant by the Company
and/or the Service Recipient, 

  
 -3- 

 
(iv) delivering to the Company already vested and owned Shares having a fair market value equal to such Tax Obligations, or (v) selling a sufficient number of such Shares otherwise
deliverable to Participant through such means as the Company may determine in its sole discretion (whether through a broker or otherwise) equal to the minimum amount that is necessary to meet the withholding requirement for such Tax Obligations (or
such greater amount as Participant may elect if permitted by the Administrator, if such greater amount would not result in adverse financial accounting consequences). To the extent determined appropriate by the Company in its discretion, it will
have the right (but not the obligation) to satisfy any Tax Obligations by reducing the number of Shares otherwise deliverable to Participant and, until determined otherwise by the Company, this will be the method by which such Tax Obligations are
satisfied. Further, if Participant is subject to tax in more than one jurisdiction between the Date of Grant and a date of any relevant taxable or tax withholding event, as applicable, Participant acknowledges and agrees that the Company and/or the
Service Recipient (and/or former employer, as applicable) may be required to withhold or account for tax in more than one jurisdiction. If Participant fails to make satisfactory arrangements for the payment of such Tax Obligations hereunder at the
time any applicable Restricted Stock Units otherwise are scheduled to vest pursuant to Sections 3 or 4, Participant will permanently forfeit such Restricted Stock Units and any right to receive Shares thereunder and such Restricted Stock Units will
be returned to the Company at no cost to the Company. Participant acknowledges and agrees that the Company may refuse to deliver the Shares if such Tax Obligations are not delivered at the time they are due. 

9.    Rights as Stockholder. Neither Participant nor any person claiming under or through Participant will have any
of the rights or privileges of a stockholder of the Company in respect of any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued, recorded on the records of the
Company or its transfer agents or registrars, and delivered to Participant (including through electronic delivery to a brokerage account). After such issuance, recordation, and delivery, Participant will have all the rights of a stockholder of the
Company with respect to voting such Shares and receipt of dividends and distributions on such Shares. 
 10.    No
Guarantee of Continued Service. PARTICIPANT ACKNOWLEDGES AND AGREES THAT THE VESTING OF THE RESTRICTED STOCK UNITS PURSUANT TO THE VESTING SCHEDULE HEREOF IS EARNED ONLY BY CONTINUING AS A SERVICE PROVIDER, WHICH UNLESS PROVIDED OTHERWISE UNDER
APPLICABLE LAW IS AT THE WILL OF THE COMPANY (OR THE SERVICE RECIPIENT) AND NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS RESTRICTED STOCK UNIT AWARD OR ACQUIRING SHARES HEREUNDER. PARTICIPANT FURTHER ACKNOWLEDGES AND AGREES THAT THIS AWARD
AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREUNDER AND THE VESTING SCHEDULE SET FORTH HEREIN DO NOT CONSTITUTE AN EXPRESS OR IMPLIED PROMISE OF CONTINUED ENGAGEMENT AS A SERVICE PROVIDER FOR THE VESTING PERIOD, FOR ANY PERIOD, OR AT ALL, AND SHALL
NOT INTERFERE IN ANY WAY WITH PARTICIPANT’S RIGHT OR THE RIGHT OF THE COMPANY (OR THE SERVICE RECIPIENT) TO TERMINATE PARTICIPANT’S RELATIONSHIP AS A SERVICE PROVIDER, SUBJECT TO APPLICABLE LAW, WHICH TERMINATION, UNLESS PROVIDED OTHERWISE
UNDER APPLICABLE LAW, MAY BE AT ANY TIME, WITH OR WITHOUT CAUSE. 

  
 -4- 

 11.    Grant is Not Transferable. Except to the limited extent
provided in Section 7, this grant and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution,
attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process,
this grant and the rights and privileges conferred hereby immediately will become null and void. 
 12.    Nature of
Grant. In accepting the grant, Participant acknowledges, understands, and agrees that: 
 (a)    the grant of the
Restricted Stock Units 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; 
 (b)    all decisions with respect to future Restricted Stock Units or other grants, if any, will be at
the sole discretion of the Company; 
 (c)    Participant is voluntarily participating in the Plan; 

(d)    the Restricted Stock Units and the Shares subject to the Restricted Stock Units are not intended to replace any
pension rights or compensation; 
 (e)    the Restricted Stock Units and the Shares subject to the Restricted Stock
Units, and the income and value of same, are not part of normal or expected compensation for purposes of calculating any severance, resignation, termination, redundancy, dismissal,
end-of-service payments, bonuses, long-service awards, pension or retirement or welfare benefits or similar payments; 

(f)    the future value of the underlying Shares is unknown, indeterminable and cannot be predicted; 

(g)    for purposes of the Restricted Stock Units, Participant’s status as a Service Provider will be considered
terminated as of the date Participant is no longer actively providing services to the Company or any Parent or Subsidiary (regardless of the reason for such termination and whether or not later to be found invalid or in breach of employment laws in
the jurisdiction where Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and unless otherwise expressly provided in this Award Agreement (including by reference in the Notice of Grant to
other arrangements or contracts) or determined by the Administrator, Participant’s right to vest in the Restricted Stock Units under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g.,
Participant’s period of service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Participant is a Service Provider or the terms
of Participant’s employment or service agreement, if any, unless Participant is providing bona fide services during such time); the Administrator shall have the exclusive discretion to determine when Participant is no longer actively providing
services for purposes of the Restricted Stock Units grant (including whether Participant may still be considered to be providing services while on a leave of absence and consistent with local law); 

  
 -5- 

 (h)    unless otherwise provided in the Plan or by the Company in its
discretion, the Restricted Stock Units and the benefits evidenced by this Award Agreement do not create any entitlement to have the Restricted Stock Units or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed
out or substituted for, in connection with any corporate transaction affecting the Shares; and 
 (i)    the following
provisions apply only if Participant is providing services outside the United States: 
 (i)    the Restricted Stock
Units and the Shares subject to the Restricted Stock Units are not part of normal or expected compensation or salary for any purpose; 

(ii)    Participant acknowledges and agrees that none of the Company, the Employer or any Parent or Subsidiary shall be
liable for any foreign exchange rate fluctuation between Participant’s local currency and the United States Dollar that may affect the value of the Restricted Stock Units or of any amounts due to Participant pursuant to the settlement of the
Restricted Stock Units or the subsequent sale of any Shares acquired upon settlement; and 
 (iii)    no claim or
entitlement to compensation or damages shall arise from forfeiture of the Restricted Stock Units resulting from the termination of Participant’s 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 Participant is a Service Provider or the terms of Participant’s employment or service agreement, if any), and in consideration of the grant of the Restricted Stock Units to which
Participant is otherwise not entitled, Participant irrevocably agrees never to institute any claim against the Company, any Parent or Subsidiary or the Service Recipient, waives his or her ability, if any, to bring any such claim, and releases
the Company, any Parent or Subsidiary and the Service Recipient from any such claim; if, notwithstanding the foregoing, any such claim is allowed by a court of competent jurisdiction, then, by participating in the Plan, Participant shall be deemed
irrevocably to have agreed not to pursue such claim and agrees to execute any and all documents necessary to request dismissal or withdrawal of such claim. 

13.    No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the
Company making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying Shares. Participant is hereby advised to consult with his or her own personal tax, legal and
financial advisors regarding his or her participation in the Plan before taking any action related to the Plan. 

14.    Data Privacy. Participant hereby explicitly and unambiguously consents to
the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Award Agreement and any other Restricted Stock Unit grant materials by and among, as applicable, the Employer, or other Service
Recipient the Company and any Parent or Subsidiary for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan. 

  
 -6- 

 Participant understands that the Company and the Service Recipient may hold certain
personal information about Participant, including, but not limited to, Participant’s name, home address and telephone number, date of birth, social insurance number or other identification number, salary, nationality, job title, any Shares or
directorships held in the Company, details of all Restricted Stock Units or any other entitlement to Shares awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of
implementing, administering and managing the Plan. 
 Participant understands that Data will be transferred to a stock plan
service provider as may be selected by the Company in the future, which is assisting the Company with the implementation, administration, and management of the Plan. Participant understands that the recipients of the Data may be located in the
United States or elsewhere, and that the recipients’ country of operation (e.g., the United States) may have different data privacy laws and protections than Participant’s country. Participant understands that if he or she resides outside
the United States, he or she may request a list with the names and addresses of any potential recipients of the Data by contacting his or her local human resources representative. Participant authorizes the Company, any stock plan service provider
selected by the Company and any other possible recipients which may assist the Company (presently or in the future) with implementing, administering and managing the Plan to receive, possess, use, retain and transfer the Data, in electronic or other
form, for the sole purpose of implementing, administering and managing his or her participation in the Plan. Participant understands that Data will be held only as long as is necessary to implement, administer and manage Participant’s
participation in the Plan. Participant understands if he or she resides outside the United States, he or she may, at any time, view Data, request additional information about the storage and processing of Data, require any necessary amendments to
Data or refuse or withdraw the consents herein, in any case without cost, by contacting in writing his or her local human resources representative. Further, Participant understands that he or she is providing the consents herein on a purely
voluntary basis. If Participant does not consent, or if Participant later seeks to revoke his or her consent, his or her status as a Service Provider and career with the Service Recipient will not be adversely affected; the only adverse consequence
of refusing or withdrawing Participant’s consent is that the Company would not be able to grant Participant Restricted Stock Units or other equity awards or administer or maintain such awards. Therefore, Participant understands that refusing or
withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that he or she may
contact his or her local human resources representative. 
 15.    Address for Notices. Any notice to be
given to the Company under the terms of this Award Agreement will be addressed to the Company at Dropbox, Inc., 333 Brannan Street, San Francisco, CA 94107, or at such other address as the Company may hereafter designate in writing. 

16.    Electronic Delivery and Acceptance. The Company may, in its sole discretion, decide to deliver any documents
related to the Restricted Stock Units awarded under the Plan or future Restricted Stock Units that may be awarded under the Plan by electronic means or request Participant’s consent to participate in the Plan by electronic means. Participant
hereby consents to 

  
 -7- 

 
receive such documents by electronic delivery and agrees to participate in the Plan through any on-line or electronic system established and maintained by
the Company or a third party designated by the Company. 
 17.    No Waiver. Either party’s failure to
enforce any provision or provisions of this Award Agreement shall not in any way be construed as a waiver of any such provision or provisions, nor prevent that party from thereafter enforcing each and every other provision of this Award Agreement.
The rights granted both parties herein are cumulative and shall not constitute a waiver of either party’s right to assert all other legal remedies available to it under the circumstances. 

18.    Successors and Assigns. The Company may assign any of its rights under this Award Agreement to single or
multiple assignees, and this Award Agreement shall inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer herein set forth, this Award Agreement shall be binding upon Participant and his or her
heirs, executors, administrators, successors and assigns. The rights and obligations of Participant under this Award Agreement may only be assigned with the prior written consent of the Company. 

19.    Additional Conditions to Issuance of Stock. If at any time the Company will determine, in its discretion,
that the listing, registration, qualification or rule compliance of the Shares upon any securities exchange or under any state, federal or non-U.S. law, the tax code and related regulations or under the
rulings or regulations of the United States Securities and Exchange Commission or any other governmental regulatory body or the clearance, consent or approval of the United States Securities and Exchange Commission or any other governmental
regulatory authority is necessary or desirable as a condition to the issuance of Shares to Participant (or his or her estate) hereunder, such issuance will not occur unless and until such listing, registration, qualification, rule compliance,
clearance, consent or approval will have been completed, effected or obtained free of any conditions not acceptable to the Company. Subject to the terms of the Award Agreement and the Plan, the Company shall not be required to issue any certificate
or certificates for Shares hereunder prior to the lapse of such reasonable period of time following the date of vesting of the Restricted Stock Units as the Administrator may establish from time to time for reasons of administrative convenience.

 20.    Language. If Participant has received this Award Agreement or any other document related to the Plan
translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control. 

21.    Interpretation. The Administrator will have the power to interpret the Plan and this Award Agreement and to
adopt such rules for the administration, interpretation and application of the Plan as are consistent therewith and to interpret or revoke any such rules (including, but not limited to, the determination of whether or not any Restricted Stock Units
have vested). All actions taken and all interpretations and determinations made by the Administrator in good faith will be final and binding upon Participant, the Company and all other interested persons. Neither the Administrator nor any person
acting on behalf of the Administrator will be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Award Agreement.

 22.    Captions. Captions provided herein are for convenience only and
are not to serve as a basis for interpretation or construction of this Award Agreement. 
 23.    Amendment,
Suspension or Termination of the Plan. By accepting this Award, Participant expressly warrants that he or she has received an Award of Restricted Stock Units under the Plan, and has received, read, and understood a description of the Plan.
Participant understands that the Plan is discretionary in nature and may be amended, suspended or terminated by the Company at any time. 

24.    Modifications to the Award Agreement. This Award Agreement constitutes the entire understanding of the
parties on the subjects covered. Participant expressly warrants that he or she is not accepting this Award Agreement in reliance on any promises, representations, or inducements other than those contained herein. Modifications to this Award
Agreement or the Plan can be made only in an express written contract executed by a duly authorized officer of the Company. Notwithstanding anything to the contrary in the Plan or this Award Agreement, the Company reserves the right to revise this
Award Agreement as it deems necessary or advisable, in its sole discretion and without the consent of Participant, to comply with Section 409A or to otherwise avoid imposition of any additional tax or income recognition under Section 409A
in connection to this Award of Restricted Stock Units. 
 25.    Governing Law; Venue; Severability. This Award
Agreement and the Restricted Stock Units are governed by the internal substantive laws, but not the choice of law rules, of California. For purposes of litigating any dispute that arises under these Restricted Stock Units or this Award Agreement,
the parties hereby submit to and consent to the jurisdiction of the State of California, and agree that such litigation will be conducted in the courts of San Francisco County, California, or the federal courts for the United States for the Northern
District of California, and no other courts, where this Award Agreement is made and/or to be performed. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this
Award Agreement shall continue in full force and effect. 
 26.    Entire Agreement. The Plan is incorporated
herein by reference. The Plan and this Award Agreement (including the appendices and exhibits referenced herein) constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior
undertakings and agreements of the Company and Participant with respect to the subject matter hereof, and may not be modified adversely to the Participant’s interest except by means of a writing signed by the Company and Participant. 

27.    Country Addendum. Notwithstanding any provisions in this Award Agreement, the Restricted Stock Unit grant
shall be subject to any special terms and conditions set forth in the appendix (if any) to this Award Agreement for Participant’s country. Moreover, if Participant relocates to one of the countries included in the Country Addendum (if any), the
special terms and conditions for such country will apply to Participant, to the extent the Company determines that the application of such terms and conditions is necessary or advisable for legal or administrative reasons. The Country Addendum
constitutes part of this Award Agreement.

RESTRICTED STOCK UNIT AGREEMENT 

COUNTRY ADDENDUM 
 TERMS AND
CONDITIONS 
 This Country Addendum includes additional terms and conditions that govern the Award of Restricted Stock Units granted to Participant
under the Plan if Participant works in one of the countries listed below. If Participant is a citizen or resident of a country (or is considered as such for local law purposes) other than the one in which he or she is currently working or if
Participant relocates to another country after receiving the Award of Restricted Stock Units, the Company will, in its discretion, determine the extent to which the terms and conditions contained herein will be applicable to Participant. 

Certain capitalized terms used but not defined in this Country Addendum shall have the meanings set forth in the Plan, and/or the Restricted Stock Unit
Agreement to which this Country Addendum is attached. 
 NOTIFICATIONS 

This Country Addendum also includes notifications relating to exchange control and other issues of which Participant should be aware with respect to his or her
participation in the Plan. The information is based on the exchange control, securities and other laws in effect in the countries listed in this Country Addendum, as of February 2018 (except as otherwise noted below). Such laws are often complex and
change frequently. As a result, the Company strongly recommends that Participant not rely on the notifications herein as the only source of information relating to the consequences of his or her participation in the Plan because the information may
be outdated when Participant vests in the Restricted Stock Units and acquires Shares, or when Participant subsequently sell Shares acquired under the Plan. 

In addition, the notifications are general in nature and may not apply to Participant’s particular situation, and the Company is not in a position to
assure Participant of any particular result. Accordingly, Participant is advised to seek appropriate professional advice as to how the relevant laws in Participant’s country may apply to Participant’s situation. 

Finally, if Participant is a citizen or resident of a country other than the one in which Participant is currently working (or is considered as such for local
law purposes) or if Participant moves to another country after receiving the Award of Restricted Stock Units, the information contained herein may not be applicable to Participant.

ADDENDUM REGARDING OFFERINGS OF RESTRICTED STOCK UNITS TO PARTICIPANTS IN FRANCE 

Type of Award 
 The RSUs are not intended to
qualify for specific tax or social security treatment in France. Therefore, the Company has decided not to provide terms and conditions of the grant in compliance with the French Commercial Code provisions on French qualified awards. 

Withholding taxes and related items 

Regardless of any action the Company, or, if different, Participant’s employer (the “Employer”)
takes with respect to any or all income tax, social security contributions, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Participant’s participation in the

PARTICIPANTS IN GERMANY 
 All capitalized
terms used not defined herein shall have the meanings assigned to them in the Dropbox, Inc. 2018 Equity Incentive Plan, as amended from time to time (the “Plan”). 
  

	1.	Taxes 

 Regardless of any action the Company or Participant’s employer (the “Employer”)
take with respect to any or all income tax, ancillary taxes (such as solidarity surcharge or church tax), wage tax withholding or other tax-related items related to Participant’s participation in the Plan
and legally applicable to Participant (“Tax-Related Items”), Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains
Participant’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Participant further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the
treatment of any Tax-Related Items in connection with any aspect of the Plan, including, but not limited to, the grant of the RSUs, the purchase of Common Stock under the Plan, the subsequent sale of Common
Stock purchased under the Plan and the receipt of any dividends on the Common Stock; and (ii) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the RSUs to reduce or eliminate Participant’s
liability for Tax-Related Items or achieve any particular tax result. Further, if Participant has become subject to tax in more than one jurisdiction between the date of grant of the RSUs and the date of any
relevant taxable or tax withholding event, as applicable, Participant acknowledges that the Company and/or the Employer (or former employer, as applicable) may be required to withhold or account for
Tax-Related Items in more than one jurisdiction. 
 Prior to any relevant taxable or tax withholding event, as
applicable, Participant will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or the
Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following:

authorization); or 

  

	 	(c)	withholding Common Stock to be issued upon vesting of the RSUs. 

 If payment or withholding of the income tax
due in connection with the RSUs is not made within 10 days following the end of the month in which the event giving rise to the liability occurs (the “Due Date”), the amount of any uncollected income tax, including ancillary taxes, shall
constitute a loan 

  
 -13- 

 
owed by Participant to the Employer effective on the Due Date. Participant agrees that the loan will bear interest at the then current market rate as published by the German Federal Bank and in
accordance with the regulations set by the German tax authorities as published in the letter dated May 19, 2015, it will be immediately due and repayable, and the Company and/or the Employer may recover it at any time thereafter by any of the
means referred to in this Section 1. 
 Notwithstanding the foregoing, if the taxes due are not collected from or paid by Participant by the Due Date,
it cannot be excluded that German tax authorities qualify the amount of any uncollected income tax as a benefit to Participant on which additional income tax are payable. The Participant will be responsible for any income tax due on this additional
benefit and for reimbursing the Company or the Employer, as applicable, any taxes collected from the Company or the Employer, as applicable, on this additional benefit, which Participant agrees that the Company or the Employer, as applicable, may
recover from Participant by any of the means referred to in this Section 1.

 DROPBOX, INC. 

2018 EQUITY INCENTIVE PLAN 

ADDENDUM REGARDING OFFERINGS OF RESTRICTED STOCK UNITS TO 

PARTICIPANTS IN SWEDEN 
 This supplement
has been prepared to provide you with the amendments that are specific for Sweden as well as a summary of the tax consequences and other issues associated with the grant of restricted stock units (hereinafter “RSUs”) by Dropbox, Inc. a
United States incorporated company (the “Company”), parent of your employer company. 
 This supplement is based on tax and other laws in effect
in Sweden as of November 1, 2017. It does not necessarily address all local tax laws that may apply to you with respect to your participation into the RSU plan. Such laws often are complex and can change frequently. As a result, the information
contained in the supplement may be outdated at the time you become vested in your RSUs or at the time you sell the shares you acquire under the plan. In addition, the information below are only applicable if you are a Swedish tax resident and your
salary is taxable in Sweden from the grant of the RSUs to the sale of the shares. 
 Please note that this supplement is general in nature and does not
discuss all of the various laws, rules and regulations that may apply. It may not apply to your particular tax or financial situation, and the Company is not in a position to assure you of any particular tax result. Accordingly, you are strongly
advised to seek appropriate professional advice as to how the tax or other laws in your country apply to your specific situation. 
 If you are a
citizen or resident of another country and/or not subject to the Swedish social insurance regime, the information contained in this supplement may not be applicable to you. 

This supplement applies to RSUs granted by the Company under terms and conditions that are summarized as follows: 

 

	 	•	 	The Company is a US incorporated company. 

  

	 	•	 	You are employed by an employer located in Sweden. 

  

	 	•	 	The grant of RSUs is a promise to receive shares for no payment by you upon vesting. You will have neither dividend nor voting rights until the end of the vesting period. At vesting, ordinary shares of the Company are
delivered to you and you become a Company’s shareholder. There is no dividend equivalent payment during the vesting period or at vesting. 

  

	 	•	 	The RSUs are not transferable and are not securities under US law and are therefore not listed. 

  
 -27- 

	 	•	 	Your grant documents will indicate terms and conditions of your RSUs. 

 PERSONAL
INCOME TAX, AND SOCIAL SECURITY INFORMATION 
 Grant

 On the date the Company grants you RSUs over ordinary shares of the Company you will not be subject to income tax or social security contributions.

 Vesting 
 On the date(s) you become vested in your
RSUs and receive ordinary shares of the Company’s common stock, you will be subject to income tax. The taxable benefit is deemed to be ordinary income from employment and is taxed at ordinary income rates. The taxable benefit upon vesting is
equal to the fair market value of the shares on the day they are delivered or in case of cash settlement, the amount of cash. 
 In addition, the taxable
benefit is subject to payment of social security contributions which are payable by your employer. 
 Sale of Shares 

When you sell your shares of the Company’s common stock, the sale is recorded as either a capital gain or loss in the capital income category. The gain or
loss is equal to the sale proceeds less an amount that corresponds to the benefit for which you were taxed upon vesting, i.e. the fair market value of the shares at delivery. As an alternative acquisition cost, you may use 20% of the sale proceeds
provided that the shares are listed. Please be aware that in case you have shares of the same class acquired at different acquisition costs you must calculate an average acquisition cost for all those shares and use that average cost as your tax
base for all shares that you sell. 
 If the sale results in a capital gain, that gain is subject to capital gains tax at a flat rate of 30% if the shares
are listed. If the sale results in a loss, the loss is deductible but deductibility may be restricted depending on your personal income tax situation. 
 If
the listed shares are held through an investment savings account (sw: investeringssparkonto, ISK), you will not be subject to capital gains tax when selling your shares. Instead, you will be subject to tax in the capital income category on a
standard income based on your total assets held on the investment savings account. Any realized capital losses on shares held through and ISK are not tax deductible. 

Dividends 
 Once you become a shareholder at vesting, you
may receive dividends if the Company decides to make such distributions. Dividends are subject to capital income tax at a flat rate of 30% if the underlying shares are listed. You may also be liable to pay US withholding tax on dividends paid to
you. You are entitled to a credit from your Swedish tax on dividend with an amount paid as US withholding tax. 

  
 -28- 

 If the listed shares are held through an investment savings account (sw: investeringssparkonto, ISK), you will
not be subject to tax on any dividends received in Sweden. You may however still be subject to US withholding tax. 
 Tax Withholding and Reporting

 Your local employer is obligated to withhold and report preliminary income tax upon vesting of your RSUs. Your employer must withhold from your salary
in the same calendar month as your RSUs vest and you receive shares of the Company’s common stock or if you receive a cash settlement. If your salary for that month does not cover the preliminary taxes that are to be withheld and reported by
your employer, then it is your responsibility to make an extra payment to the Swedish Tax Agency (Sw. Skatteverket) during the next calendar year in connection to your personal income tax return. In addition, you are obligated by law to report the
vesting of your RSUs to your employer as soon as possible after vesting and not later than 15 January of the year following the year of vesting. Please note that your employer’s withholding and reporting obligations arise at the time of
vesting, even though you have additional time to fulfil your reporting obligation. 
 It is your responsibility to report taxable income resulting from the
vesting of your RSUs, and the sale of shares, in your annual income tax return. The annual income tax return must be submitted to the Swedish Tax Agency by May 2 of the year following the income year, i.e., the year in which you earned the
income in question. 
 EXCHANGE CONTROL INFORMATION 

There are no exchange controls or similar restrictions that would generally affect the holding or vesting of RSUs or the holding or disposal of Company shares.
However, foreign and local banks or financial institutions (including brokers) are required to submit income statements to the Swedish Tax Agency regarding cross-border transactions, or parts of such transactions, in excess of SEK 150,000. 

AMENDMENTS 
 Section 14 (Data Privacy)
shall not apply.
