Form of Indemnification Agreement

 Exhibit 10.1 
 INDEMNITY AGREEMENT 
 This Indemnity Agreement (this “Agreement”), dated as
of                 , 2008, (the “Effective Date”) is made by and between Broncus Technologies, Inc., a Delaware corporation (the
“Company”), and
                                        ,
an individual who is a director and/or officer of the Company (“Indemnitee”). 
 RECITALS 
 A. The Company is aware that competent and experienced persons are increasingly reluctant to serve as directors or officers of corporations unless they
are protected by comprehensive liability insurance and/or indemnification agreements, due to their increased exposure to litigation costs and risks resulting from their service to such corporations, and because this exposure frequently bears no
reasonable relationship to their compensation as directors and officers. 
 B. Section 145 (“Section 145”) of
the General Corporation Law of Delaware, under which the Company is organized (the “Law”) empowers the Company to indemnify by agreement its officers, directors, employees and agents, and persons who serve, at the request of
the Company, as directors, officers, employees or agents of other corporations or enterprises, and expressly provides that the indemnification provided by the Law is not exclusive. 
 C. Based on their experience as business managers, the Board of Directors of the Company (the “Board”) has concluded that, to
retain and attract talented and experienced individuals to serve as officers and directors of the Company, and to encourage such individuals to take the business risks necessary for the success of the Company, it is necessary for the Company
contractually to indemnify officers and directors and to assume for itself liability for expenses and damages in connection with claims against such officers and directors in connection with their service to the Company. 
 D. The Company desires and has requested Indemnitee to serve or continue to serve as a director or officer of the Company. The Company desires that
Indemnitee be free from undue concern regarding claims for damages arising out of or related to such services, which may impair the free exercise of Indemnitee’s best business judgment on behalf of the Company, its subsidiaries and other
enterprises affiliated with the Company. 
 NOW, THEREFORE, in consideration of the mutual promises made in this Agreement, the
parties hereto, intending to be legally bound, hereby agree as follows: 
 1. Definitions. For purposes of this Agreement, the
following terms have the meanings defined below: 
 1.1 Affiliate. An “affiliate” of the Company means
any foreign or domestic corporation, partnership, limited liability company, joint venture, firm, trust, enterprise and/or other entity (each, an “entity”) that is an “affiliate” of the Company within the meaning of

Control” shall be deemed to have occurred if, after the Effective Date: 
 (a) any “person” (as defined below)
increases such person’s beneficial ownership in the Company’s Voting Securities (as defined below) by at least twenty (20) percentage points without the prior approval of at least two-thirds (2/3) of the Incumbent Directors in
office immediately prior to such person attaining such percentage interest; 
 (b) any “person” (as defined below) is or becomes
the “beneficial owner” (as defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), directly or indirectly, of Voting Securities of the Company representing thirty percent
(30%) or more of the total combined voting power of all the Company’s then outstanding Voting Securities; 
 (c) during any period
of twenty-four (24) consecutive months that begins on or after the Effective Date, the Incumbent Directors (as defined below) cease for any reason to constitute at least two-thirds (2/3) of the members of the Board then in office (where
for purposes hereof, with respect to any particular period of twenty-four (24) consecutive months, the term “Incumbent Directors” means (i) the individuals who at the beginning of such twenty-four
(24) consecutive month period constituted the Board and (ii) each other individual whose election or nomination for election to the Board during such twenty-four (24) month period was approved by a vote of at least two-thirds
(2/3) of the directors in office who were either members of the Board at the beginning of such twenty-four (24) month period or whose election or nomination for election to the Board was approved as described in this clause (ii));

 (d) the Company is a party to a consummated merger or consolidation as a result of which the Voting Securities of the Company outstanding
immediately prior thereto do not represent (either by remaining outstanding or by being converted into voting securities of the surviving entity of such merger or consolidation or of a parent of such surviving entity), at least fifty percent
(50%) of the total combined voting power represented by the voting securities of such surviving entity or a parent of such surviving entity immediately after consummation of such merger or consolidation; or 
  

 2 

 (e) the stockholders of the Company approve a plan of complete liquidation or dissolution of the Company
or an agreement for the sale or disposition by the Company (in one transaction or a series of transactions) of all or substantially all of the Company’s assets (other than a sale or disposition of all or substantially all the
Company’s assets to another entity that, immediately after such transaction is owned, directly or indirectly, by the stockholders of the Company immediately prior to the transaction in substantially the same proportion as their ownership of the
Company’s capital stock immediately prior to such transaction if the acquiring entity assumes this Agreement). 
 For purposes of this
Section 1.3: (a) the term “person” will have the meaning given to such term in Section 13(d) and 14(d) of the Exchange Act except that it shall exclude (i) a trustee or other fiduciary holding securities
under an employee benefit plan of the Company or (ii) a corporation or other entity owned directly or indirectly by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company); and

 1.4 Company. The “Company” includes, in the event of a merger or consolidation involving the Company, the
corporation or other entity surviving or resulting from such merger or consolidation. 
 1.5 Expenses. The term
“expenses” includes all direct and indirect costs of any type or nature whatsoever (including, without limitation, all attorneys’ fees and related disbursements and other out-of-pocket costs) actually and reasonably
incurred by Indemnitee in connection with the investigation, defense or appeal of, or being a witness in, a proceeding (as defined below), or establishing or enforcing a right to indemnification or advancement of expenses under this Agreement or
Section 145; provided, however, that the term “expenses” shall not include any judgments, fines, ERISA excise taxes or penalties or amounts paid in settlement of a proceeding. 
 1.6 Independent Counsel. “Independent Counsel” means a law firm, or an attorney-at-law, that is experienced in
matters of corporation law and that is not at the time in question, nor has been for the then-past three (3) years, retained to represent: (a) the Company or Indemnitee in any matter material to the Company or Indemnitee; or (b) any
other party to the proceeding giving rise to a claim for indemnification or advancement of expenses under this Agreement with respect to which such Independent Counsel is to have involvement under this Agreement; provided, however,
that notwithstanding the foregoing, the term “Independent Counsel” shall not include any person who, under 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 (it being acknowledged that no such conflict of interest will be deemed to exist solely due to such law firm or attorney-at-law (i) entering into any
agreement with the Company relating to its, his or her retention to act as Independent Counsel for purposes of this Agreement or (ii) taking any actions contemplated as Independent Counsel under this Agreement). 
 1.7 Proceeding. A “proceeding” means any threatened, pending or completed action, lawsuit, alternative dispute

this Section or (c) by one or more of such entity’s subsidiaries as defined in clause (a) of this Section. 
 2. Agreement
to Serve. Indemnitee agrees to serve and/or to continue to serve as an officer or director of the Company, at the will of the Company (or under separate written agreement, if any such written agreement exists), in the capacity in which
Indemnitee serves the Company as of the Effective Date, faithfully and to the best of Indemnitee’s ability, so long as Indemnitee is duly appointed or elected and qualified in accordance with the applicable provisions of the charter documents
of the Company or any subsidiary of the Company; provided, however, that Indemnitee may at any time and for any reason resign from such position (subject to any contractual obligation that Indemnitee may have assumed apart from this
Agreement), and the Company or any subsidiary shall have no obligation under this Agreement to continue Indemnitee in any such position. 
 3. Directors’ and Officers’ Insurance. The Company shall, to the extent that the Board determines it to be economically reasonable, maintain a policy of directors’ and officers’ liability insurance
(“D&O Insurance”), on such terms and conditions and in such coverage amounts as may be approved by the Board from time to time. 
 4. Mandatory Indemnification. 
 4.1 Third Party Actions. If Indemnitee was or is a party
or is threatened to be made a party to any proceeding (other than an action by or in the right of the Company) by reason of the fact that Indemnitee is or was an agent of the Company, or by reason of anything done or not done by Indemnitee in
Indemnitee’s capacity as an agent of the Company, then, subject to the provisions of Section 8 and the exceptions set forth in Section 9, the Company shall indemnify Indemnitee against any and all expenses and liabilities of any type
whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) actually and reasonably incurred by Indemnitee in connection with the investigation, defense, settlement or appeal of such
proceeding or being a witness in such proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal action or proceeding,
Indemnitee had no reasonable cause to believe that Indemnitee’s conduct was unlawful. 
 4.2 Actions by or in Right of the
Company. If Indemnitee was or is a party to, or is threatened to be made a party to, any proceeding by or in the right of the Company to procure a judgment in its favor by reason of the fact that Indemnitee is or was an agent of the Company, or
by reason of anything done or not done by Indemnitee in Indemnitee’s capacity as an agent of the Company, then, subject to the provisions of Section 8 and the exceptions set forth in Section 9, the Company shall indemnify Indemnitee
against any amounts paid in settlement of 

  

 4 

 
any such proceeding and all expenses actually and reasonably incurred by Indemnitee in connection with the investigation, defense, settlement or appeal of
such proceeding or being a witness in such proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in, or not opposed to, the best interests of the Company; except that no indemnification under
this Section 4.2 shall be made in respect of any claim, issue or matter as to which Indemnitee shall have been finally adjudged to be liable to the Company by a court of competent jurisdiction due to Indemnitee’s willful misconduct of a
culpable nature in the performance of Indemnitee’s duty to the Company, unless and only to the extent that the Delaware Court of Chancery or the court in which such 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 indemnity for such amounts which the Delaware Court of Chancery or such other court shall deem proper. 
 4.3 Witness Expenses in Certain Proceedings. Notwithstanding any other provision of this Agreement to the contrary, to the extent that
Indemnitee was or is, by reason of the fact that Indemnitee is or was an agent of the Company, a witness in any proceeding to which Indemnitee is not made a party or of which Indemnitee is not the subject, the Company shall indemnify Indemnitee
against all expenses actually and reasonably incurred by Indemnitee or on Indemnitee’s behalf solely in connection with Indemnitee’s being a witness in such proceeding (including on appeal), and in preparing to be a witness in such
proceeding without the need for any determination with respect to Indemnitee’s conduct pursuant to Section 8 of this Agreement. 
 4.4 Exception for Amounts Covered by Insurance. Notwithstanding the foregoing, the Company shall not be obligated to indemnify Indemnitee for expenses or liabilities of any type whatsoever (including, but not limited to,
judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) to the extent such have been paid directly to Indemnitee by D&O Insurance. To the extent that any payment payable by the carrier of D&O Insurance in respect of
such expenses or liabilities has previously been paid or advanced to Indemnitee by the Company, the parties agree that the Company shall be subrogated to the rights of Indemnitee to receive such payments from the D&O Insurance carrier and that
Indemnitee will take all actions reasonably necessary to turn over or otherwise cause the Company to receive any such payment from the D&O Insurance carrier. 
 5. Partial Indemnification and Contribution. 
 5.1 Partial Indemnification. If
Indemnitee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of any expenses or liabilities of any type whatsoever (including, but not limited to, judgments, fines, ERISA excise taxes or
penalties and amounts paid in settlement) incurred by Indemnitee in the investigation, defense, settlement or appeal of a proceeding or in being a witness in a proceeding but is not entitled, however, to indemnification for all of the total amount
thereof, then the Company shall nevertheless indemnify Indemnitee for such total amount except as to the portion thereof to which Indemnitee is not entitled to indemnification. 
 5.2 Contribution. If Indemnitee is not entitled to the indemnification provided in Section 4 for any reason other than the statutory
limitations set forth in the Law, then in respect of any threatened, pending or completed proceeding in which the Company is jointly 

  

 5 

 
liable with Indemnitee (or would be if joined in such proceeding), the Company shall contribute to the amount of expenses (including attorneys’ fees),
judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in such proportion as is appropriate to reflect (a) the relative benefits received by the
Company on the one hand and Indemnitee on the other hand from the transaction from which such proceeding arose and (b) the relative fault of the Company on the one hand and of Indemnitee on the other hand in connection with the events which
resulted in such expenses, judgments, fines, ERISA excise taxes or penalties or settlement amounts, as well as any other relevant equitable considerations. The relative fault of the Company on the one hand and of Indemnitee on the other hand shall
be determined by reference to, among other things, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent the circumstances resulting in such expenses, judgments, fines, ERISA excise taxes,
penalties or settlement amounts. The Company agrees that it would not be just and equitable if contribution pursuant to this Section 5.2 were determined by pro rata allocation or any other method of allocation that does not take account of the
foregoing equitable considerations. 
 6. Mandatory Advancement of Expenses. 
 6.1 Advancement. Subject to the provisions of Section 6.2 and the exceptions in Section 9 below and except as prohibited by law,
the Company shall advance all expenses incurred by Indemnitee in connection with the investigation, defense, settlement or appeal of any proceeding to which Indemnitee is a party or is threatened to be made a party or witness by reason of the fact
that Indemnitee is or was an agent of the Company or by reason of anything done or not done by Indemnitee in Indemnitee’s capacity as an agent of the Company. Indemnitee hereby undertakes and agrees to promptly repay to the Company such amounts
as are so advanced by the Company to Indemnitee only if, and to the extent that, it shall ultimately be determined that Indemnitee is not entitled to be indemnified by the Company under the provisions of this Agreement, the Certificate of
Incorporation or Bylaws of the Company, the Law or otherwise with respect to the proceeding or proceedings for which such expenses were advanced. Subject to the foregoing, the advances to be made hereunder shall be paid by the Company to Indemnitee
within thirty (30) days following delivery of a written request therefor by Indemnitee to the Company which includes reasonable verification of the expenses incurred by Indemnitee for which an advance is sought. 
 6.2 Exception. Notwithstanding the foregoing provisions of Section 6.1, the Company shall not be obligated to advance any expenses to
Indemnitee arising from a lawsuit filed or brought directly by the Company against Indemnitee or a criminal proceeding resulting from a complaint made by the Company if an Independent Majority (as defined below) of the Board reasonably determines in
good faith, within thirty (30) days of Indemnitee’s request to be advanced such expenses, that the facts known to them at the time such determination is made demonstrate clearly and convincingly that Indemnitee acted in bad faith with
respect to the subject matter of such lawsuit or proceeding or the facts, circumstances or events from which such lawsuit or criminal proceeding arose (a “Section 6.2 Determination”). If such a determination that Indemnitee
acted in bad faith is made, then Indemnitee may have such decision reviewed by another forum, in the manner set forth in Section 8, with all references therein to “indemnification” being deemed to refer to “advancement of
expenses,” and the burden of proof shall be on the Company to demonstrate clearly and convincingly that, based on 

  

 6 

 
the facts known at the time, Indemnitee acted in bad faith. Notwithstanding the foregoing, if the Company has undergone a Change in Control after the
occurrence of the acts or omissions of Indemnitee that are the primary focus of the lawsuit or criminal proceeding in question, then the Section 6.2 Determination with respect to such lawsuit or criminal proceeding must instead be made in good
faith by Independent Counsel selected by an Independent Majority of the Board. As used in this Section, an “Independent Majority” of the Board means: (i) a majority of the members of the Board other than Indemnitee (if
Indemnitee is then a member of the Board); or (ii) an absolute majority of the members of the Board if Indemnitee is not then a member of the Board. 
 7. Notice and Other Indemnification Procedures. 
 7.1 Notice of Proceeding.
Promptly after receipt by Indemnitee of notice of the commencement of or the threat of commencement of any proceeding, Indemnitee shall, if Indemnitee believes that indemnification with respect thereto may be sought from the Company under this
Agreement, notify the Company in writing of the commencement or threat of commencement thereof. 
 7.2 Notice to D&O Insurance
Carrier. If, at the time of the receipt of a notice of the commencement of a proceeding pursuant to Section 7.1, the Company has D&O Insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the
insurers providing such D&O Insurance in accordance with the procedures set forth in the applicable D&O Insurance policy or policies. The Company shall thereafter use diligent, good faith efforts to cause such insurers to promptly pay, on
behalf of Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such D&O Insurance policies. 
 7.3 Assumption of Defense by the Company; Settlement. In the event the Company shall be obligated to advance Indemnitee’s expenses with respect to any proceeding, the Company, if appropriate, shall be entitled, at its
option, to assume Indemnitee’s defense of such proceeding, with counsel approved by Indemnitee (which approval shall not be unreasonably withheld 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 under this Agreement or otherwise for any fees of counsel subsequently incurred by
Indemnitee with respect to the same proceeding, provided that: (a) Indemnitee shall have the right to employ Indemnitee’s own counsel in any such proceeding at Indemnitee’s own expense; (b) Indemnitee shall have the
right to employ Indemnitee’s own counsel in connection with any such proceeding if such counsel serves solely in a review, observer, advice and counseling capacity and does not otherwise materially control or participate in the defense of such
proceeding, and the Company shall advance, and/or indemnify Indemnitee for, the fees of such counsel to the extent the Company would be required to do so under the terms of this Agreement (without regard to the provisions of this Section 7.3);
and (c) if (i) the employment of counsel by Indemnitee has been previously authorized by the Company, or (ii) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in
the conduct of any such defense or (iii) the Company shall not, in fact, have employed counsel to assume Indemnitee’s defense of such proceeding, then the Company shall advance, and/or indemnify Indemnitee for, the fees of
Indemnitee’s counsel to the extent the Company would be required to 

  

 7 

 
do so under the terms of this Agreement (without regard to the provisions of this Section 7.3). The Company shall not be required to obtain the consent
of Indemnitee to the settlement of any proceeding as to which the Company has assumed the defense if the Company assumes the full and sole responsibility and liability for such settlement and the settlement grants Indemnitee a complete and
unqualified release in respect of the potential liability arising from such proceeding. 
 8. Determination of Right to Indemnification.

 8.1 Successful Defense. To the extent Indemnitee has been successful on the merits or otherwise in the defense of any
proceeding referred to in Section 4.1 or 4.2 of this Agreement or in the defense of any claim, issue or matter described therein, then subject to the provisions of Section 4.4, the Company shall indemnify Indemnitee against expenses
actually and reasonably incurred by him in connection with the investigation, defense or appeal of such proceeding, or such claim, issue or matter, as the case may be. 
 8.2 Other Circumstances. In the event that Indemnitee seeks indemnification under Section 4.1 or 4.2 of this Agreement and Section 8.1 is inapplicable to such claim for indemnification, or does
not apply to the entire proceeding, then subject to the provisions of Section 4.4, the Company shall indemnify Indemnitee as provided in Section 4.1 or 4.2, as applicable, unless the Company shall claim and prove by clear and convincing
evidence to a forum listed in Section 8.3 that Indemnitee has not met the applicable standard of conduct required to entitle Indemnitee to indemnification under Section 4.1 or 4.2, as applicable. 
 8.3 Selection of Forum to Determine Entitlement to Indemnification. In the event that the Company claims that Indemnitee is not entitled to
indemnification pursuant to Section 4.1 or 4.2, then Indemnitee shall be entitled to select the forum in which the validity of the Company’s claim under Section 8.2 that Indemnitee is not entitled to indemnification will be heard by
one (1) forum from among the following, except that Indemnitee can select a forum consisting of the stockholders of the Company only with the prior written approval of the Company that is duly authorized by the Board: 

(a) A majority of a quorum of the Board consisting of directors who are not parties to the proceeding for which indemnification is being sought;

 (b) The stockholders of the Company; 
 (c) Independent Counsel mutually agreed upon by Indemnitee and the Board, which Independent Counsel shall make such determination in a written opinion; 
 (d) A panel of three (3) arbitrators, one of whom is selected by the Company, another of whom is selected by Indemnitee and the last of whom is
selected by the first two arbitrators so selected, who will conduct the arbitration in San Jose, California pursuant to the Commercial Arbitration Rules of the American Arbitration Association; or 
 (e) The Court of Chancery of Delaware or other court having jurisdiction of the subject matter and the parties. 
  

 8 

 8.4 Submission of Claim by Company. As soon as practicable, and in no event later than
thirty (30) days after the forum has been selected pursuant to Section 8.3, the Company shall, at its own expense, submit to the selected forum its claim that the Indemnitee is not entitled to indemnification, and the Company shall act in
the utmost good faith to assure Indemnitee a complete opportunity to defend against such claim. 
 8.5 Further Proceedings. If
the forum selected in accordance with Section 8.3 is not a court, then after the final decision of such forum is rendered, the Company or Indemnitee shall have the right to apply to the Court of Chancery of Delaware, the court in which the
proceeding giving rise to Indemnitee’s claim for indemnification is or was pending or any other court having jurisdiction of the subject matter and the parties, for the purpose of appealing the decision of such forum, provided that such
right is executed within sixty (60) days after the final decision of such forum is rendered. If the forum selected in accordance with Section 8.3 is a court, then the rights of the Company or the Indemnitee to appeal any decision of such
court shall be governed by the applicable laws and rules governing appeals of the decision of such court. 
 8.6 Court
Proceeding. If the forum selected by Indemnitee pursuant to Section 8.3 to determine whether Indemnitee is entitled to indemnification is not a court described in Section 8.3(e) and such forum shall not have made a determination within
120 days after the date on which the Company is required by Section 8.3 to submit to such forum its claim that Indemnitee is not entitled to such indemnification, then Indemnitee shall be entitled to apply to the Court of Chancery of Delaware
or other court described in Section 8.3(e) to have Indemnitee’s request for indemnification adjudicated by such court in lieu of having the determination made by such forum. The Company shall not oppose Indemnitee’s right to seek any
such adjudication. 
 8.7 No Presumption. For purposes of this Agreement, the termination of any proceeding by judgment, order,
settlement (whether with or without court approval) or conviction, or upon a plea of nolo contendere, or its equivalent, shall not create a presumption that Indemnitee did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by this Agreement or applicable law. 
 8.8 Section 8
Matters. Notwithstanding any other provision in this Agreement to the contrary, the Company shall indemnify Indemnitee against all expenses incurred by Indemnitee in connection with any hearing or proceeding under this Section 8 involving
Indemnitee and against all expenses incurred by Indemnitee in connection with any other proceeding between the Company and Indemnitee involving the interpretation or enforcement of the rights of Indemnitee under this Agreement unless a court of
competent jurisdiction finds that each of the material claims and/or defenses of Indemnitee in any such proceeding was frivolous or not made in good faith. 
 9. Exceptions. Notwithstanding any other provision of this Agreement to the contrary, the Company shall not be obligated pursuant to the terms of this Agreement: 
 9.1 Claims Initiated by Indemnitee. To indemnify or advance expenses to Indemnitee with respect to proceedings or claims initiated or
brought voluntarily by Indemnitee and not by way of defense, except with respect to (a) proceedings specifically authorized by the Board or (b) (subject to the provisions of Section 6.2 and Section 8.8) proceedings brought
by Indemnitee to establish or enforce a right to indemnification and/or advancement of expenses arising under this Agreement, the charter documents of the Company or any subsidiary or any statute or law; or 
  

 9 

 9.2 Unauthorized Settlements. To indemnify Indemnitee hereunder for any amounts paid in
settlement of a proceeding unless the Company consents in advance in writing to such settlement, which consent shall not be unreasonably withheld; or 
 9.3 Certain Securities Law Actions. To indemnify or advance expenses to Indemnitee on account of any suit in which judgment is rendered against Indemnitee for an accounting of profits made from the
purchase or sale by the Indemnitee of securities of the Company pursuant to the provisions of Section 16(b) of the Exchange Act, or similar provisions of any federal, state or local statutory law or Section 306(a) of the Sarbanes-Oxley Act
of 2002; or 
 9.4 Unlawful Indemnification. To indemnify Indemnitee if a final decision by a court having jurisdiction in the
matter shall determine that such indemnification is not lawful. In this respect, the Company and Indemnitee have been advised that the Securities and Exchange Commission takes the position that indemnification for liabilities arising under the
federal securities laws is against public policy and is, therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication. 
 10. Non-Exclusivity. The provisions for indemnification and advancement of expenses set forth in this Agreement shall not be deemed exclusive of
any other rights which Indemnitee may have under any provision of law, the Company’s Certificate of Incorporation or Bylaws, the vote of the Company’s stockholders or disinterested directors, other agreements or otherwise, both as to
action in Indemnitee’s official capacity and to action in another capacity while occupying his position as an agent of the Company, and Indemnitee’s rights hereunder shall continue after Indemnitee has ceased acting as an agent of the
Company and shall inure to the benefit of Indemnitee’s heirs, executors and administrators. 
 11. General Provisions.

 11.1 Interpretation of Agreement. It is understood that the parties hereto intend this Agreement to be interpreted
and enforced so as to provide indemnification and advancement of expenses to Indemnitee to the fullest extent now or hereafter permitted by law, except as expressly limited herein. 
 11.2 Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or unenforceable for any
reason whatsoever, then: (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including, without limitation, all portions of any paragraphs of this Agreement containing any such provision held to be
invalid, illegal or unenforceable that are not themselves invalid, illegal or unenforceable) 

  

 10 

 
shall not in any way be affected or impaired thereby; and (b) to the fullest extent possible, the provisions of this Agreement (including, without
limitation, all portions of any paragraphs of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable) shall be construed so as to give effect to the intent
manifested by the provision held invalid, illegal or unenforceable and to give effect to Section 11.1. 
 11.3 Modification
and Waiver. No supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both of the parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a
waiver of any other provision hereof (whether or not similar), nor shall such waiver constitute a continuing waiver. 
 11.4
Subrogation. In the event of a payment by the Company 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 documents required and shall
do all acts that may be necessary or desirable to secure such rights and to enable the Company effectively to bring suit to enforce such rights. 
 11.5 Counterparts. This Agreement may be executed in one or more counterparts, which shall together constitute one agreement. 
 11.6 Successors and Assigns. The terms of this Agreement shall bind, and shall inure to the benefit of, the successors and assigns of the parties hereto; provided however that,
Indemnitee may not assign Indemnitee’s rights under this Agreement except by will or the laws of descent and distribution.

 131997 Stock Option Plan and forms of stock option agreement

 Exhibit 10.2 
 BRONCUS TECHNOLOGIES, INC. 
 1997 STOCK OPTION PLAN 
 As Adopted February 11, 1997 and 
 as amended through January 10, 2007 
 1. PURPOSE. The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential contributions are important to the success of the Company, its Parent and Subsidiaries, by offering them an opportunity to participate in the Company’s future performance
through awards of Options. Capitalized terms not defined in the text are defined in Section 21. This Plan is intended to be a written compensatory benefit plan within the meaning of Rule 701 promulgated under the Securities Act. 
 2. SHARES SUBJECT TO THE PLAN. 
 2.1 Number of Shares Available. Subject to Sections 2.2 and 16, the total number of Shares reserved and available for grant and issuance pursuant to this Plan will be 21,800,000 Shares. Shares
that are subject to issuance upon exercise of an Option but cease to be subject to such Option for any reason other than exercise of such Option will be available for issuance in connection with future Options. At all times the Company will reserve
and keep available a sufficient number of Shares as will be required to satisfy the requirements of all outstanding Options granted under this Plan. 
 2.2 Adjustment of Shares. In the event that the number of outstanding shares of the Company’s Common Stock is changed by a stock dividend, recapitalization, stock split, reverse stock split,
subdivision, combination, reclassification or similar change in the capital structure of the Company without consideration, then (a) the number of Shares reserved for issuance under this Plan and (b) the Exercise Prices of and number of
Shares subject to outstanding Options, will be proportionately adjusted, subject to any required action by the Board or the shareholders of the Company and compliance with applicable securities laws; provided, however, that fractions
of a Share will not be issued but will either be paid in cash at Fair Market Value of such fraction of a Share or will be rounded down to the nearest whole Share, as determined by the Committee. 
 3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted only to employees (including officers and directors who are also
employees) of the Company or of a Parent or Subsidiary of the Company. Nonqualified Stock Options (as defined in Section 5 below) may be granted to employees, officers, directors and consultants of the Company or any Parent or Subsidiary of the
Company; provided such consultants render bona fide services not in connection with the offer and sale of securities in a capital-raising transaction. A person may be granted more than one Option under this Plan. 
 4. ADMINISTRATION. 
 4.1
Committee Authority. This Plan will be administered by the Committee or the Board acting as the Committee. Subject to the general purposes, terms and conditions of this Plan, and to the direction of the Board, the Committee will have
full power to implement and carry out this Plan. Without limitation, the Committee will have the authority to: 
  

	 	(a)	construe and interpret this Plan, any Stock Option Agreement (as defined in Section 5 below) and any other agreement or document executed pursuant to this Plan;

  

	 	(b)	prescribe, amend and rescind rules and regulations relating to this Plan; 

  

	 	(c)	select persons to receive Options; 

	 	(d)	determine the form and terms of Options; 

  

	 	(e)	determine the number of Shares or other consideration subject to Options; 

  

	 	(f)	determine whether Options will be granted singly, in combination with, in tandem with, in replacement of, or as alternatives to, any other incentive or compensation plan of the
Company or any Parent or Subsidiary of the Company; 

  

	 	(g)	grant waivers of Plan or Option conditions; 

  

	 	(h)	determine the vesting and exercisability of Options; 

  

	 	(i)	correct any defect, supply any omission, or reconcile any inconsistency in this Plan, any Option, any Stock Option Agreement (as defined in Section 5 below) or any Exercise
Agreement (as defined in Section 5 below); 

  

	 	(j)	determine whether an Option has been earned; and 

  

	 	(k)	make all other determinations necessary or advisable for the administration of this Plan. 

 4.2 Committee Discretion. Any determination made by the Committee with respect to any Option will be made in its sole discretion at the time
of grant of the Option or, unless in contravention of any express term of this Plan or Option, and subject to Section 5.9, at any later time, and such determination will be final and binding on the Company and on all persons having an interest
in any Option under this Plan. The Committee may delegate to one or more officers of the Company the authority to grant an Option under this Plan to Participants who are not Insiders of the Company. 
 5. OPTIONS. The Committee may grant Options to eligible persons and will determine whether such Options will be Incentive Stock Options
within the meaning of the Code (“ISOs”) or Nonqualified Stock Options (“NQSOs”), the number of Shares subject to the Option, the Exercise Price of the Option, the period during which the Option may be
exercised, and all other terms and conditions of the Option, subject to the following: 
 5.1 Form of Option Grant. Each
Option granted under this Plan will be evidenced by an Agreement which will expressly identify the Option as an ISO or an NQSO (“Stock Option Agreement”), and will be in such form and contain such provisions (which need
not be the same for each Participant) as the Committee may from time to time approve, and which will comply with and be subject to the terms and conditions of this Plan. 
 5.2 Date of Grant. The date of grant of an Option will be the date on which the Committee makes the determination to grant such Option, unless otherwise specified by the Committee. The Stock Option
Agreement and a copy of this Plan will be delivered to the Participant within a reasonable time after the granting of the Option. 
 5.3
Exercise Period. Options may be exercisable immediately (subject to repurchase pursuant to Section 10 of this Plan) or may be exercisable within the times or upon the events determined by the Committee as set forth in the Stock
Option Agreement governing such Option; provided, however, that no Option will be exercisable after the expiration of ten (10) years from the date the Option is granted; and provided further that no ISO granted to a
person who directly or by attribution owns more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of any Parent or Subsidiary of the Company
(“Ten Percent Shareholder”) will be exercisable after the expiration of five (5) years from the date the ISO is granted. The Committee also may provide for Options to become exercisable at one
time or from time to time, periodically or otherwise, in such number of Shares or percentage of Shares as the Committee determines. Subject to earlier termination of the Option as provided herein, Participants, other than officers, directors or
consultants of the Company or of a Parent or Subsidiary of the Company, shall have the right to exercise an Option granted hereunder at the rate of at least twenty percent (20%) per year over five (5) years from the date such Option is
granted. 
  

 2 

 5.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when
the Option is granted and may not be less than 85% of the Fair Market Value of the Shares on the date of grant; provided that (i) the Exercise Price of an ISO will not be less than 100% of the Fair Market Value of the Shares on the date of
grant and (ii) the Exercise Price of any Option granted to a Ten Percent Shareholder will not be less than 110% of the Fair Market Value of the Shares on the date of grant. Payment for the Shares purchased must be made in accordance with
Section 6 of this Plan. 
 5.5 Method of Exercise. Options may be exercised only by delivery to the Company of a
written stock option exercise agreement (the “Exercise Agreement”) in a form approved by the Committee (which need not be the same for each Participant), stating the number of Shares being purchased, the restrictions
imposed on the Shares purchased under such Exercise Agreement, if any, and such representations and agreements regarding Participant’s investment intent and access to information and other matters, if any, as may be required or desirable by the
Company to comply with applicable securities laws, together with payment in full of the Exercise Price, and any applicable taxes, for the number of Shares being purchased. 
 5.6 Termination. Subject to earlier termination pursuant to Sections 16 and 17 and notwithstanding the exercise periods set forth in the Stock
Option Agreement, exercise of an Option will always be subject to the following: 
  

	 	(a)	If the Participant is Terminated for any reason except death, Disability or Cause then the Participant may exercise such Participant’s Options, only to the extent that such
Options are exercisable upon the Termination Date, no later than three (3) months after the Termination Date (or such shorter time period, not less than thirty (30) days, as may be specified in the Stock Option Agreement) or such longer
time period not exceeding five (5) years after the Termination Date as may be determined by the Committee, with any exercise beyond three (3) months after the Termination Date deemed to be an NQSO, but in any event, no later than the
expiration date of the Options. 

  

	 	(b)	If the Participant is Terminated because of Participant’s death or Disability (or the Participant dies within three (3) months after a Termination other than because of
Participant’s death, Disability or Cause), then Participant’s Options may be exercised, only to the extent that such Options are exercisable by Participant on the Termination Date and must be exercised by Participant (or Participant’s
legal representative or authorized assignee), no later than twelve (12) months after the Termination Date (or such shorter time period, not less than six (6) months, as may be specified in the Stock Option Agreement) or such longer time
period not exceeding five (5) years after the Termination Date as may be determined by the Committee, with any exercise beyond (a) three (3) months after the Termination Date when the Termination is for any reason other than the
Participant’s death or disability, within the meaning of Section 22(e)(3) of the Code, or (b) twelve (12) months after the Termination Date when the Termination is for Participant’s death or disability, within the meaning of
Section 22(e)(3) of the Code, deemed to be an NQSO, but in any event no later than the expiration date of the Options. 

  

	 	(c)	If the Participant is terminated for Cause, then Participant’s Options shall expire on such Participant’s Termination Date, or at such later time and on such conditions as
determined by the Committee. 

  

 3 

 5.7 Limitations on Exercise. The Committee may specify a reasonable minimum number of
Shares that may be purchased on exercise of an Option, provided that such minimum number will not prevent Participant from exercising the Option for the full number of Shares for which it is then exercisable. 
 5.8 Limitations on ISOs. The aggregate Fair Market Value (determined as of the date of grant) of Shares with respect to which ISOs are
exercisable for the first time by a Participant during any calendar year (under this Plan or under any other incentive stock option plan of the Company or any Parent or Subsidiary of the Company) will not exceed $100,000. If the Fair Market Value of
Shares on the date of grant with respect to which ISOs are exercisable for the first time by a Participant during any calendar year exceeds $100,000, then the Options for the first $100,000 worth of Shares to become exercisable in such calendar year
will be ISOs and the Options for the amount in excess of $100,000 that become exercisable in that calendar year will be NQSOs. In the event that the Code or the regulations promulgated thereunder are amended after the Effective Date (as defined in
Section 17 below) to provide for a different limit on the Fair Market Value of Shares permitted to be subject to ISOs, then such different limit will be automatically incorporated herein and will apply to any Options granted after the effective
date of such amendment. 
 5.9 Modification, Extension or Renewal. The Committee may modify, extend or renew
outstanding Options and authorize the grant of new Options in substitution therefor, provided that any such action may not, without the written consent of a Participant, impair any of such Participant’s rights under any Option previously
granted. Any outstanding ISO that is modified, extended, renewed or otherwise altered will be treated in accordance with Section 424(h) of the Code. The Committee may reduce the Exercise Price of outstanding Options without the consent of
Participants affected by a written notice to them; provided, however, that the Exercise Price may not be reduced below the minimum Exercise Price that would be permitted under Section 5.4 of this Plan for Options granted on the
date the action is taken to reduce the Exercise Price. 
 5.10 No Disqualification. Notwithstanding any other provision in this
Plan, no term of this Plan relating to ISOs will be interpreted, amended or altered, nor will any discretion or authority granted under this Plan be exercised, so as to disqualify this Plan under Section 422 of the Code or, without the consent
of the Participant affected, to disqualify any ISO under Section 422 of the Code. 
 6.
PAYMENT FOR SHARE PURCHASES. 
 6.1 Payment. Payment for Shares purchased pursuant to this Plan may be made
in cash (by check) or, where expressly approved for the Participant by the Committee and where permitted by law: 
  

	 	(a)	by cancellation of indebtedness of the Company to the Participant; 

  

	 	(b)	by surrender of shares that either: (1) have been owned by the Participant for more than six (6) months and have been paid for within the meaning of SEC Rule 144 (and, if
such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares); or (2) were obtained by the Participant in the public market; 

  

	 	(c)	by tender of a full recourse promissory note having such terms as may be approved by the Committee and bearing interest at a rate sufficient to avoid imputation of income under
Sections 483 and 1274 of the Code; provided, however, that Participants who are not employees or directors of the Company will not be entitled to purchase Shares with a promissory note unless the note is adequately secured by
collateral other than the Shares; 

  

	 	(d)	by waiver of compensation due or accrued to the Participant for services rendered; 

  

	 	(e)	provided that a public market for the Company’s stock exists: 

  

	 	(1)	through a “same day sale” commitment from the Participant and a broker-dealer that is a member of the National Association of Securities Dealers (an
“NASD Dealer”) whereby the Participant irrevocably elects to exercise the Option and to sell a portion of the Shares so purchased to pay for the Exercise Price, and whereby the NASD Dealer irrevocably commits upon
receipt of such Shares to forward the Exercise Price directly to the Company; or 

  

 4 

	 	(2)	through a “margin” commitment from the Participant and an NASD Dealer whereby the Participant irrevocably elects to exercise the Option and to pledge the Shares so
purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to
the Company; or 

  

	 	(f)	by any combination of the foregoing. 

 6.2
Loan Guarantees. The Committee may help the Participant pay for Shares purchased under this Plan by authorizing a guarantee by the Company of a third-party loan to the Participant. 
 7. WITHHOLDING TAXES. 
 7.1 Withholding Generally. Whenever Shares are to be issued in satisfaction of Options granted under this Plan, the Company may require the Participant to remit to the Company an amount sufficient to satisfy federal, state and
local withholding tax requirements prior to the delivery of any certificate or certificates for such Shares. Whenever, under this Plan, payments in satisfaction of Options are to be made in cash, such payment will be net of an amount sufficient to
satisfy federal, state, and local withholding tax requirements. 
 7.2 Stock Withholding. When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of any Option that is subject to tax withholding and the Participant is obligated to pay the Company the amount required to be withheld, the Committee may in its sole
discretion allow the Participant to satisfy the minimum withholding tax obligation by electing to have the Company withhold from the Shares to be issued that number of Shares having a Fair Market Value equal to the minimum amount required to be
withheld, determined on the date that the amount of tax to be withheld is to be determined. All elections by a Participant to have Shares withheld for this purpose will be made in accordance with the requirements established by the Committee and be
in writing in a form acceptable to the Committee. 
 8. PRIVILEGES OF STOCK OWNERSHIP. 
 8.1 Voting and Dividends. No Participant will have any of the rights of a shareholder with respect to any Shares until the Shares are
issued to the Participant. After Shares are issued to the Participant, the Participant will be a shareholder and have all the rights of a shareholder with respect to such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that the Participant will have no right to retain such stock dividends or stock distributions with respect to Unvested Shares that are repurchased pursuant to Section 10.

 8.2 Financial Statements. The Company will provide financial statements to each Participant prior to such Participant’s
purchase of Shares under this Plan, and to each Participant annually during the period such Participant has Options outstanding, or as otherwise required or permitted under Section 260.140.46 of Title 10 of the California Code of Regulations.
Notwithstanding the foregoing, the Company will not be required to provide such financial statements to Participants whose services in connection with the Company assure them access to equivalent information. 
  

 5 

 9. TRANSFERABILITY. Options granted under this Plan, and any interest therein, will not be
transferable or assignable by Participant, and may not be made subject to execution, attachment or similar process, otherwise than by will or by the laws of descent and distribution. During the lifetime of the Participant an Option will be
exercisable only by the Participant, and any elections with respect to an Option, may be made only by the Participant. 
 10.
RESTRICTIONS ON SHARES. At the discretion of the Committee, the Company may reserve to itself and/or its assignee(s) in the Stock Option Agreement (a) a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, unless otherwise not permitted by Section 25102(o) of the California Corporations Code, provided, that such right of first refusal terminates upon the Company’s initial
public offering of Common Stock pursuant to an effective registration statement filed under the U.S. Securities Act of 1933, as amended and/or (b) a right to repurchase Unvested Shares held by a Participant following such Participant’s
Termination at any time within ninety (90) days after Participant’s Termination Date (or, in the case of securities issued upon exercise of an Option after the Participant’s Termination Date, within 90 days after the date of such
exercise) for cash and/or cancellation of purchase money indebtedness, at the Participant’s Exercise Price, provided, that to the extent the Participant is not an officer, director or consultant of the Company or of a Parent or
Subsidiary of the Company, such right of repurchase lapses at the rate of at least twenty percent (20%) per year over five (5) years from the date of grant of the Option. 
 11. CERTIFICATES. All certificates for Shares or other securities delivered under this Plan will be subject to such stock transfer orders,
legends and other restrictions as the Committee may deem necessary or advisable, including restrictions under any applicable federal, state or foreign securities law, or any rules, regulations and other requirements of the SEC or any stock exchange
or automated quotation system upon which the Shares may be listed or quoted. 
 12. ESCROW; PLEDGE OF SHARES. To
enforce any restrictions on a Participant’s Shares, the Committee may require the Participant to deposit all certificates representing Shares, together with stock powers or other instruments of transfer approved by the Committee, appropriately
endorsed in blank, with the Company or an agent designated by the Company to hold in escrow until such restrictions have lapsed or terminated, and the Committee may cause a legend or legends referencing such restrictions to be placed on the
certificates. Any Participant who is permitted to execute a promissory note as partial or full consideration for the purchase of Shares under this Plan will be required to pledge and deposit with the Company all or part of the Shares so purchased as
collateral to secure the payment of Participant’s obligation to the Company under the promissory note; provided, however, that the Committee may require or accept other or additional forms of collateral to secure the payment of
such obligation. In connection with any pledge of the Shares, Participant will be required to execute and deliver a written pledge agreement in such form as the Committee will from time to time approve. The Shares purchased with the promissory note
may be released from the pledge on a pro rata basis as the promissory note is paid. 
 13.
EXCHANGE AND BUYOUT OF OPTIONS. The Committee may, at any time or from time to time, authorize the Company, with the consent of the respective Participants, to issue new Options in exchange for the surrender and
cancellation of any or all outstanding Options. The Committee may at any time buy from a Participant an Option previously granted with payment in cash, shares of Common Stock of the Company (including restricted stock) or other consideration, based
on such terms and conditions as the Committee and the Participant may agree. 
 14.
SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. This Plan is intended to comply with Section 25102(o) of the California Corporations Code. Any provision of the Plan which is inconsistent with
Section 25102(o) shall, without further act or amendment by the Company or the Board, be reformed to comply with the requirements of Section 25102(o). An Option will not be effective unless such Option is in compliance with all applicable
federal and state securities laws, rules and regulations of any governmental body, and the requirements of any stock exchange or automated quotation system upon which the Shares may then be listed or quoted, as they are in effect on the date of
grant of the Option and also on the date of exercise or other issuance. Notwithstanding any other provision in this Plan, the Company will have no obligation to issue or deliver certificates 

  

 6 

 
for Shares under this Plan prior to (a) obtaining any approvals from governmental agencies that the Company determines are necessary or advisable,
and/or (b) compliance with any exemption, completion of any registration or other qualification of such Shares under any state or federal law or ruling of any governmental body that the Company determines to be necessary or advisable. The
Company will be under no obligation to register the Shares with the SEC or to effect compliance with the exemption, registration, qualification or listing requirements of any state securities laws, stock exchange or automated quotation system, and
the Company will have no liability for any inability or failure to do so. 
 15. NO OBLIGATION TO EMPLOY.
Nothing in this Plan or any Option granted under this Plan will confer or be deemed to confer on any Participant any right to continue in the employ of, or to continue any other relationship with, the Company or any Parent or Subsidiary of the
Company or limit in any way the right of the Company or any Parent or Subsidiary of the Company to terminate Participant’s employment or other relationship at any time, with or without cause. 
 16. CORPORATE TRANSACTIONS. 
 16.1 Assumption or Replacement of Options by Successor. In the event of (a) a dissolution or liquidation of the Company, (b) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned subsidiary, a reincorporation of the Company in a different jurisdiction, or other transaction in which there is no substantial change in the shareholders of the
Company or their relative stock holdings and the Options granted under this Plan are assumed, converted or replaced by the successor corporation, which assumption will be binding on all Participants), (c) a merger in which the Company is the
surviving corporation but after which shareholders of the Company immediately prior to such merger (other than any shareholder which merges, or which owns or controls another corporation which merges, with the Company in such merger) cease to own
their shares or other equity interests in the Company, or (d) the sale of substantially all of the assets of the Company, any or all outstanding Options may be assumed, converted or replaced by the successor corporation (if any), which
assumption, conversion or replacement will be binding on all Participants. In the alternative, the successor corporation may substitute equivalent Options or provide substantially similar consideration to Participants as was provided to shareholders
(after taking into account the existing provisions of the Options). The successor corporation may also issue, in place of outstanding Shares of the Company held by the Participant, substantially similar shares or other property subject to repurchase
restrictions and other provisions no less favorable to the Participant than those which applied to such outstanding Shares immediately prior to such transaction described in this Subsection 16.1. In the event such successor corporation (if any) does
not assume or substitute Options, as provided above, pursuant to a transaction described in this Subsection 16.1, then notwithstanding any other provision in this Plan to the contrary, such Options will expire on such transaction at such time and on
such conditions as the Board will determine. 
 16.2 Other Treatment of Options. Subject to any greater rights granted
to Participants under the foregoing provisions of this Section 16, in the event of the occurrence of any transaction described in Section 16.1, any outstanding Options will be treated as provided in the applicable agreement or plan of
merger, consolidation, dissolution, liquidation or sale of assets. 
 16.3
Assumption of Options by the Company. The Company, from time to time, also may substitute or assume outstanding options granted by another company, whether in connection with an acquisition of such other company or
otherwise, by either (a) granting an Option under this Plan in substitution of such other company’s option, or (b) assuming such option as if it had been granted under this Plan if the terms of such assumed option could be applied to
an Option granted under this Plan. Such substitution or assumption will be permissible if the holder of the substituted or assumed option would have been eligible to be granted an Option under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an option granted by another company, the terms and conditions of such option will remain unchanged (except that the exercise price and the number and nature of shares issuable upon
exercise of any such option will be adjusted appropriately pursuant to Section 424(a) of the Code). In the event the Company elects to grant a new Option rather than assuming an existing option, such new Option may be granted with a similarly
adjusted Exercise Price. 
  

 7 

 17. ADOPTION AND SHAREHOLDER APPROVAL. This Plan will become effective on
the date that it is adopted by the Board (the “Effective Date”). This Plan will be approved by the shareholders of the Company (excluding Shares issued pursuant to this Plan), consistent with applicable laws, within twelve
(12) months before or after the Effective Date. Upon the Effective Date, the Board may grant Options pursuant to this Plan; provided, however, that no Option may be exercised prior to shareholder approval of this Plan. In the
event that shareholder approval is not obtained within twelve (12) months before or after the date this Plan is adopted by the Board, all Options granted hereunder will be canceled. 
 18. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided herein, this Plan will terminate ten (10) years from
the Effective Date or, if earlier, the date of shareholder approval. This Plan and all agreements hereunder shall be governed by and construed in accordance with the laws of the State of California. 
 19. AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9, the Board may at any time terminate or amend this
Plan in any respect, including without limitation amendment of any form of Stock Option Agreement or instrument to be executed pursuant to this Plan; provided, however, that the Board will not, without the approval of the shareholders
of the Company, amend this Plan in any manner that requires such shareholder approval pursuant to the Code or the regulations promulgated thereunder as such provisions apply to ISO plans. 
 20. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the Board, the submission of this Plan to the
shareholders of the Company for approval, nor any provision of this Plan will be construed as creating any limitations on the power of the Board to adopt such additional compensation arrangements as it may deem desirable, including, without
limitation, the granting of stock options otherwise than under this Plan, and such arrangements may be either generally applicable or applicable only in specific cases. 
 21. DEFINITIONS. As used in this Plan, the following terms will have the following meanings:

 1. Grant of Option. The Company hereby grants to Participant an option
(this “Option”) to purchase the total number of shares of Common Stock of the Company set forth above in Total Option Shares (the “Shares”) at the Exercise Price Per Share set forth above (the
“Exercise Price”), subject to all of the terms and conditions of this Agreement and the Plan. If designated as an Incentive Stock Option above, this Option is intended to qualify as an “incentive stock option”
(“ISO”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”). 
 2. Exercise Period. 
 2.1 Exercise Period of Option. This Option is
immediately exercisable although the Shares issued upon exercise of the Option will be subject to the restrictions on transfer and Repurchase Options set forth in Sections 8 and 9 below. Provided Participant continues to provide services to the
Company or to any Parent or Subsidiary of the Company, the Shares issuable upon exercise of this Option will become vested with respect to 1/48th of the Shares on
                     (the “First Vesting Date”) and thereafter at the end of each full succeeding month
after the First Vesting Date an additional 1/48th of the Shares will become vested until the Shares are vested with respect to 100% of the Shares, provided that if application of the vesting percentage causes a fractional share, such share shall be
rounded down to the nearest whole share. Notwithstanding any provision in the Plan or this Agreement to the contrary, Options for Unvested Shares (as defined in Section 2.2 of this Agreement) will not be exercisable after Participant’s
Termination Date. 

 2.2 Vesting of Options. Shares that are vested pursuant to the schedule set forth in
Section 2.1 are “Vested Shares.” Shares that are not vested pursuant to the schedule set forth in Section 2.1 are “Unvested Shares.” Unvested Shares may not be sold or
otherwise transferred by Participant without the Company’s prior written consent. 
 2.3 Expiration. This Option shall expire on
the Expiration Date set forth above or earlier as provided in Section 3 below. 
 3. Termination. 
 3.1 Termination for Any Reason Except Death, Disability or Cause. If Participant is Terminated for any reason, except
death, Disability or Cause, this Option, to the extent (and only to the extent) that it is exercisable by Participant on the Termination Date, may be exercised by Participant no later than three (3) months after the Termination Date, but in any
event no later than the Expiration Date. 
 3.2 Termination Because of Death or Disability. If Participant
is Terminated because of death or Disability of Participant (or Participant dies within three (3) months after Termination other than for Cause or because of Participant’s death or Disability), this Option, to the extent that it is
exercisable by Participant on the Termination Date, may be exercised by Participant (or Participant’s legal representative) no later than twelve (12) months after the Termination Date, but in any event no later than the Expiration Date.
Any exercise beyond (a) three (3) months after the Termination Date when the Termination is for any reason other than the Participant’s death or disability, within the meaning of Section 22(e)(3) of the Code; or (b) twelve
(12) months after the Termination Date when the termination is for Participant’s death or disability, within the meaning of Section 22(e)(3) of the Code, is deemed to be an NQSO. 
 3.3 Termination for Cause. If Participant is terminated for Cause, then this Option will expire on Participant’s Termination Date, or at
such later time and on such conditions as determined by the Committee. 
 3.4 No Obligation to Employ. Nothing in the
Plan or this Agreement shall confer on Participant any right to continue in the employ of, or other relationship with, the Company or any Parent or Subsidiary of the Company, or limit in any way the right of the Company or any Parent or Subsidiary
of the Company to terminate Participant’s employment or other relationship at any time, with or without Cause. 
 4.
Manner of Exercise. 
 4.1 Stock Option Exercise Agreement. To exercise this Option, Participant
(or in the case of exercise after Participant’s death or incapacity, Participant’s executor, administrator, heir or legatee, as the case may be) must deliver to the Company an executed stock option exercise agreement in the form attached
hereto as Exhibit A, or in such other form as may be approved by the Company from time to time (the “Exercise Agreement”), which shall set forth, inter alia, Participant’s election to exercise
this Option, the number of Shares being purchased, any restrictions imposed on the Shares and any representations, warranties and agreements regarding Participant’s investment intent and access to information as may be required by the Company
to comply with applicable securities laws. If someone other than Participant exercises this Option, then such person must submit documentation reasonably acceptable to the Company that such person has the right to exercise this Option. 

4.2 Limitations on Exercise. This Option may not be exercised unless such exercise is in compliance with all applicable federal and
state securities laws, as they are in effect on the date of exercise. This Option may not be exercised as to fewer than one hundred (100) Shares unless it is exercised as to all Shares as to which this Option is then exercisable. 
  

 - 2 - 

 4.3 Payment. The Exercise Agreement shall be accompanied by full payment of the Exercise Price
for the Shares being purchased in cash (by check), or where permitted by law: 
  

	 	(a)	by cancellation of indebtedness of the Company to the Participant; 

  

	 	(b)	by surrender of shares of the Company’s Common Stock that: (1) either (A) have been owned by Participant for more than six (6) months and have been paid for
within the meaning of SEC Rule 144 (and, if such shares were purchased from the Company by use of a promissory note, such note has been fully paid with respect to such shares); or (B) were obtained by Participant in the open public market; and
(2) are clear of all liens, claims, encumbrances or security interests; 

  

	 	(c)	by waiver of compensation due or accrued to Participant for services rendered; 

  

	 	(d)	provided that a public market for the Company’s stock exists, (1) through a “same day sale” commitment from Participant and a broker-dealer that is a member of
the National Association of Securities Dealers (an “NASD Dealer”) whereby Participant irrevocably elects to exercise this Option and to sell a portion of the Shares so purchased to pay for the Exercise Price and whereby
the NASD Dealer irrevocably commits upon receipt of such Shares to forward the Exercise Price directly to the Company, or (2) through a “margin” commitment from Participant and an NASD Dealer whereby Participant irrevocably
elects to exercise this Option and to pledge the Shares so purchased to the NASD Dealer in a margin account as security for a loan from the NASD Dealer in the amount of the Exercise Price, and whereby the NASD Dealer irrevocably commits upon receipt
of such Shares to forward the Exercise Price directly to the Company; or 

  

	 	(e)	by any combination of the foregoing. 

 4.4
Tax Withholding. Prior to the issuance of the Shares upon exercise of this Option, Participant must pay or provide for any applicable federal, state and local withholding obligations of the Company. If the Committee permits, Participant
may provide for payment of withholding taxes upon exercise of this Option by requesting that the Company retain Shares with a Fair Market Value equal to the minimum amount of taxes required to be withheld. In such case, the Company shall issue the
net number of Shares to the Participant by deducting the Shares retained from the Shares issuable upon exercise. 
 4.5
Issuance of Shares. Provided that the Exercise Agreement and payment are in form and substance satisfactory to counsel for the Company, the Company shall issue the Shares registered in the name of Participant, Participant’s
authorized assignee, or Participant’s legal representative, and shall deliver certificates representing the Shares with the appropriate legends affixed thereto. 
 5. Notice of Disqualifying Disposition of ISO Shares. If this Option 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 (a) the date two (2) years after the Date of Grant, and (b) the date one (1) year after transfer of such Shares to Participant upon exercise of this Option, Participant shall 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 from the early disposition by payment in cash or out of the
current wages or other compensation payable to Participant. 
 6. Compliance with Laws and Regulations. The
Plan and this Agreement are intended to comply with Section 25102(o) of the California Corporations Code. Any provision of this Agreement which is inconsistent with Section 25102(o) shall, without further act or amendment by the Company or
the Board, be reformed to comply with the requirements of Section 25102(o). The exercise of this Option and the issuance and transfer of Shares shall be subject to compliance by the Company and Participant with all applicable requirements of

  

 - 3 - 

 
federal and state securities laws and with all applicable requirements of any stock exchange on which the Company’s Common Stock may be listed at the
time of such issuance or transfer. Participant understands that the Company is under no obligation to register or qualify the Shares with the SEC, any state securities commission or any stock exchange to effect such compliance. 
 7. Nontransferability of Option. This Option may not be transferred in any manner other than by will or by the laws of descent
and distribution and may be exercised during the lifetime of Participant only by Participant. The terms of this Option shall be binding upon the executors, administrators, successors and assigns of Participant. 
 8. Company’s Repurchase Option for Unvested Shares. The Company, or its assignee, shall have the option to repurchase
Participant’s Unvested Shares (as defined in Section 2.2 of this Agreement) on the terms and conditions set forth in the Exercise Agreement (the “Repurchase Option”) if Participant is Terminated (as defined in the
Plan) for any reason, or no reason, including without limitation Participant’s death, Disability (as defined in the Plan), voluntary resignation or termination by the Company with or without Cause. 
 9. Company’s Right of First Refusal. Unvested Shares may not be sold or otherwise transferred by Participant
without the Company’s prior written consent. Before any Vested Shares held by Participant or any transferee of such Vested Shares (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred
(including without limitation a transfer by gift or operation of law), the Company and/or its assignee(s) shall have an assignable right of first refusal to purchase the Vested Shares to be sold or transferred (the “Offered Shares”)
on the terms and conditions set forth in the Exercise Agreement (the “Right of First Refusal”). The Company’s Right of First Refusal will terminate upon the Company’s initial public offering of Common Stock
pursuant to an effective registration statement filed under the U.S. Securities Act of 1933, as amended. 
 10.
Tax Consequences. Set forth below is a brief summary as of the Effective Date of the Plan of some of the federal and California tax consequences of the exercise of this Option and disposition of the Shares. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. PARTICIPANT SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
 10.1 Exercise of ISO. If this Option qualifies as an ISO, there will be no regular federal or California income tax liability upon the
exercise of this Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as a tax preference item for federal alternative minimum tax purposes and may subject the
Participant to the alternative minimum tax in the year of exercise. 
 10.2
Exercise of Nonqualified Stock Option. If this Option does not qualify as an ISO, there may be a regular federal and California income tax liability upon the exercise of this Option. Participant will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Participant is or was an employee of the Company, the Company
will be required to withhold from Participant’s compensation or collect from Participant and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 
 10.3 Disposition of Shares. The following tax consequences may apply upon disposition of Shares. 
 a. ISOs. If the Shares are held for more than twelve (12) months after the date of the transfer of the Shares pursuant to the exercise of an
ISO and are disposed of more than two years after the Date of Grant, any gain realized on disposition of the Shares will be treated as capital gain for federal and California income tax purposes. If Shares purchased under an ISO are disposed of
within the applicable one year or two year 

  

 - 4 - 

 
period, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the excess, if any,
of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. 
 b. Nonqualified Stock Options. If the
Shares are held for more than twelve (12) months after the date of the transfer of the Shares pursuant to the exercise of a Nonqualified Stock Option, any gain realized on disposition of the Shares will be treated as Long-Term Capital Gain.

 c. Withholding. The Company may be required to withhold from Participant’s compensation or collect from Participant and pay
to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 
 10.4.
Section 83(b) Election for Unvested Shares. With respect to Unvested Shares, which are subject to the Repurchase Option, unless an election is filed by the Participant with the Internal Revenue Service (and, if necessary, the proper
state taxing authorities), within 30 days of the purchase of the Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar state tax provisions, if applicable) to be taxed currently on any difference between the
Exercise Price of the Unvested Shares and their Fair Market Value on the date of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to the Participant, measured by the excess, if
any, of the Fair Market Value of the Unvested Shares at the time they cease to be Unvested Shares, over the Exercise Price of the Unvested Shares. 
 10.5 Section 409A. Participant acknowledges that, under Section 409A of the Code, receipt of a stock option with an exercise price per share that is less than the fair market value of the stock subject to the option at
the time of grant can result in significant adverse tax consequences to the Participant, including without limitation the imputation of taxable income to the Participant on the difference between the exercise price and fair market value as the
option vests and the imposition of an additional excise tax on the Participant. The Company does not make any representation to Participant that the Exercise Price of this Option was equal to the fair market value per share of the Shares as of
the Date of Grant. Participant acknowledges and agrees that neither the Company, nor its officers, directors, stockholders, employees, attorneys, agents, successors or assigns, shall have any liability to Participant should it be determined
hereafter that the Exercise Price of this Option is less than the fair market value per share of the Shares as of the Date of Grant. If Participant desires advice regarding Section 409A of the Code with respect to this Option, Participant
should consult with Participant’s own tax and/or financial advisors. Participant acknowledges that Participant is under no obligation to accept this Option. 
 11. Privileges of Stock Ownership. Participant shall not have any of the rights of a shareholder with respect to any Shares until the Shares are issued to Participant. 
 12. Interpretation. Any dispute regarding the interpretation of this Agreement shall be submitted by Participant or the Company to the
Committee for review. The resolution of such a dispute by the Committee shall be final and binding on the Company and Participant. 
 13.
Entire Agreement. The Plan is incorporated herein by reference. This Agreement and the Plan constitute the entire agreement of the parties and supersede all prior undertakings and agreements with respect to the subject matter hereof.

 14. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in
writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or delivered to Participant shall be in writing and addressed to Participant at the address indicated above or to
such other address as such party may designate in writing from time to time to the Company. All notices shall be deemed to have been given or delivered upon: personal delivery; three (3) days after deposit in the United States mail by certified
or registered mail (return receipt requested); one (1) business day after deposit with any return receipt express courier (prepaid); or one (1) business day after transmission by facsimile, rapifax or telecopier. 
  

 - 5 - 

 15. Successors and Assigns. The Company may assign any of its rights under this
Agreement, including its rights to repurchase Shares under the Repurchase Option and the Right of First Refusal. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer set forth herein, this Agreement shall be binding upon Participant and Participant’s heirs, executors, administrators, legal representatives, successors and assigns. 
 16. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of California as such
laws are applied to agreements between California residents entered into and to be performed entirely within California. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable, then such provision will be
enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable. 
 17.
Acceptance. Participant hereby acknowledges receipt of a copy of the Plan and this Agreement. Participant has read and understands the terms and provisions thereof, and accepts this Option subject to all the terms and conditions of the
Plan and this Agreement. Participant acknowledges that there may be adverse tax consequences upon exercise of this Option or disposition of the Shares and that Participant should consult a tax adviser prior to such exercise or disposition.

 IN WITNESS WHEREOF, the Company has caused this Agreement to be executed in triplicate by its duly authorized representative and
Participant has executed this Agreement in triplicate as of the Date of Grant.

Representations and Warranties of Purchaser. Purchaser represents and warrants to the Company that: 
 3.1
Agrees to Terms of the Plan. Purchaser has received a copy of the Plan and the Stock Option Agreement, has read and understands the terms of the Plan, the Stock Option Agreement and this Exercise Agreement, and agrees
to be bound by their terms and conditions. Purchaser acknowledges that there may be adverse tax consequences upon exercise of the Option or disposition of the Shares, and that Purchaser should consult a tax adviser prior to such exercise or
disposition. 
 3.2 Purchase for Own Account for Investment. Purchaser is purchasing the Shares for
Purchaser’s own account for investment purposes only and not with a view to, or for sale in connection with, a distribution of the Shares within the meaning of the Securities Act of 1933, as amended (the “Securities Act”).
Purchaser has no present intention of selling or otherwise disposing of all or any portion of the Shares and no one other than Purchaser has any beneficial ownership of any of the Shares. 
 3.3 Access to Information. Purchaser has had access to all information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that Purchaser reasonably considers important in making the decision to purchase the Shares, and Purchaser has had ample opportunity to ask questions of the Company’s representatives concerning such
matters and this investment. 
 3.4 Understanding of Risks. Purchaser is fully aware of: (i) the highly speculative
nature of the investment in the Shares; (ii) the financial hazards involved; (iii) the lack of liquidity of the Shares and the restrictions on transferability of the Shares (e.g., that Purchaser may not be able to sell or dispose of
the Shares or use them as collateral for loans); (iv) the qualifications and backgrounds of the management of the Company; and (v) the tax consequences of investment in the Shares. Purchaser is capable of evaluating the merits and risks of
this investment, has the ability to protect Purchaser’s own interests in this transaction and is financially capable of bearing a total loss of this investment.

solicitation in connection with the offer, sale and purchase of the Shares. 
 4. Compliance with Securities Laws.

 4.1 Compliance with Federal Securities Laws. Purchaser understands and acknowledges that the Shares have
not been registered with the Securities and Exchange Commission (“SEC”) under the Securities Act and that, notwithstanding any other provision of the Stock Option Agreement to the contrary, the exercise of any rights to purchase any
Shares is expressly conditioned upon compliance with the Securities Act and all applicable state securities laws. Purchaser agrees to cooperate with the Company to ensure compliance with such laws. The Shares are being issued under the Securities
Act pursuant to the exemption provided by SEC Rule 701. 

 4.2 Compliance with California Securities Laws. The Plan, The stock option
agreement, and this Agreement are intended to comply with Section 25102(o) of the California Corporations Code. Any provision of this Agreement which is inconsistent with Section 25102(o) shall, without further act or amendment by the
Company or the Board, be reformed to comply with the requirements of Section 25102(o). THE SALE OF THE SECURITIES THAT ARE THE SUBJECT OF THIS EXERCISE AGREEMENT, IF NOT YET QUALIFIED WITH THE CALIFORNIA COMMISSIONER OF CORPORATIONS AND NOT
EXEMPT FROM SUCH QUALIFICATION, IS SUBJECT TO SUCH QUALIFICATION, AND THE ISSUANCE OF SUCH SECURITIES, AND THE RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL UNLESS THE SALE IS EXEMPT. THE RIGHTS OF THE
PARTIES TO THIS EXERCISE AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION BEING AVAILABLE. 
 5.
Restricted Securities. 
 5.1 No Transfer Unless Registered or Exempt. Purchaser understands
that Purchaser may not transfer any Shares unless such Shares are registered under the Securities Act or qualified under applicable state securities laws or unless, in the opinion of counsel to the Company, exemptions from such registration and
qualification requirements are available. Purchaser understands that only the Company may file a registration statement with the SEC and that the Company is under no obligation to do so with respect to the Shares. Purchaser has also been advised
that exemptions from registration and qualification may not be available or may not permit Purchaser to transfer all or any of the Shares in the amounts or at the times proposed by Purchaser. 
 5.2 SEC Rule 144. In addition, Purchaser has been advised that SEC Rule 144 promulgated under the Securities Act, which permits certain
limited sales of unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for a minimum holding period, after they have been purchased and paid for (within
the meaning of Rule 144). Purchaser understands that Rule 144 may indefinitely restrict transfer of the Shares so long as Purchaser remains an “affiliate” of the Company or if “current public information” about the Company (as
defined in Rule 144) is not publicly available. Effective April 29, 1997, the Rule 144 holding period will be one year and in certain cases two years. 
 5.3 SEC Rule 701. The Shares are issued pursuant to SEC Rule 701 promulgated under the Securities Act and may become freely tradeable by non-affiliates (under limited conditions regarding the method
of sale) 90 days after the first sale of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the SEC, subject to the lengthier market standoff agreement contained in
Section 7 of this Exercise Agreement or any other agreement entered into by Purchaser. Affiliates must comply with the provisions (other than the holding period requirements) of Rule 144. 
 6. Restrictions on Transfers. 
 6.1 Disposition of Shares. Purchaser hereby agrees that Purchaser shall make no disposition of the Shares (other than as permitted by this Agreement) unless and until: 
 (a) Purchaser shall have notified the Company of the proposed disposition and provided a written summary of the terms and conditions of the proposed
disposition; 

 (b) Purchaser shall have complied with all requirements of this Exercise Agreement applicable to the
disposition of the Shares; 
 (c) Purchaser shall have provided the Company with written assurances, in form and substance satisfactory to
counsel for the Company, that (i) the proposed disposition does not require registration of the Shares under the Securities Act or (ii) all appropriate action necessary for compliance with the registration requirements of the Securities
Act or of any exemption from registration available under the Securities Act (including Rule 144) has been taken; and 
 (d) Purchaser shall
have provided the Company with written assurances, in form and substance satisfactory to the Company, that the proposed disposition will not result in the contravention of any transfer restrictions applicable to the Shares pursuant to the provisions
of the Commissioner Rules identified in Section 4.2. 
 6.2 Restriction on Transfer. Purchaser shall not transfer,
assign, grant a lien or security interest in, pledge, hypothecate, encumber or otherwise dispose of any of the Shares which are subject to the Company’s Repurchase Option or the Company’s Right of First Refusal, except as permitted by this
Exercise Agreement. 
 6.3 Transferee Obligations. Each person (other than the Company) to whom the Shares are transferred by
means of one of the permitted transfers specified in this Exercise Agreement must, as a condition precedent to the validity of such transfer, acknowledge in writing to the Company that such person is bound by the provisions of this Exercise
Agreement and that the transferred Shares are subject to (i) both the Company’s Repurchase Option and the Company’s Right of First Refusal granted hereunder and (ii) the market stand-off provisions of Section 7, to the same
extent such Shares would be so subject if retained by the Purchaser. 
 7. Market Standoff Agreement. Purchaser
agrees in connection with any registration of the Company’s securities that, upon the request of the Company or the underwriters managing any public offering of the Company’s securities, Purchaser will not sell or otherwise dispose of any
Shares without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed 180 days) after the effective date of such registration requested by such managing underwriters and subject to
all restrictions as the Company or the underwriters may specify. Purchaser will enter into any agreement reasonably required by the underwriters to implement the foregoing. 
 8. Company’s Repurchase Option for Unvested Shares. The Company, or its assignee, shall have the option to repurchase Purchaser’s
Unvested Shares (as defined in Section 2.2 of the Stock Option Agreement) on the terms and conditions set forth in this Section (the “Repurchase Option”) if Purchaser is Terminated (as defined in the Plan) for any reason,
or no reason, including without limitation Purchaser’s death, Disability (as defined in the Plan), voluntary resignation or termination by the Company with or without cause. 
 8.1 Termination and Termination Date. In case of any dispute as to whether Purchaser is Terminated, the Committee shall have
discretion to determine whether Purchaser has been Terminated and the effective date of such Termination (the “Termination Date”). 
 8.2 Exercise of Repurchase Option. At any time within ninety (90) days after the Purchaser’s Termination Date (or, in the case of securities issued upon exercise after the
Purchaser’s Termination Date, within ninety (90) days after the date of such exercise), the Company, or its assignee, may elect to repurchase the Purchaser’s Unvested Shares by giving Purchaser written notice of exercise of the
Repurchase Option. 

 8.3 Calculation of Repurchase Price for Unvested Shares. The Company or its
assignee shall have the option to repurchase from Purchaser (or from Purchaser’s personal representative as the case may be) the Unvested Shares at the Purchaser’s Exercise Price, proportionately adjusted for any stock split or similar
change in the capital structure of the Company as set forth in Section 2.2 of the Plan. 
 8.4
Payment of Repurchase Price. The repurchase price shall be payable, at the option of the Company or its assignee, by check or by cancellation of all or a portion of any outstanding indebtedness of Purchaser to the Company or
such assignee, or by any combination thereof. The repurchase price shall be paid without interest within sixty (60) days after exercise of the Repurchase Option. 
 8.5 Right of Termination Unaffected. Nothing in this Exercise Agreement shall be construed to limit or otherwise affect in any manner whatsoever the right or power of the Company (or any Parent or
Subsidiary of the Company) to terminate Purchaser’s employment or other relationship with Company (or the Parent or Subsidiary of the Company) at any time, for any reason or no reason, with or without cause. 
 9. Company’s Right of First Refusal. Unvested Shares may not be sold or otherwise transferred by Purchaser without
the Company’s prior written consent. Before any Vested Shares held by Purchaser or any transferee of such Vested Shares (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including
without limitation a transfer by gift or operation of law), the Company and/or its assignee(s) shall have an assignable right of first refusal to purchase the Vested Shares to be sold or transferred (the “Offered Shares”) on the
terms and conditions set forth in this Section (the “Right of First Refusal”). 
 9.1
Notice of Proposed Transfer. The Holder of the Offered Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer
the Offered Shares; (ii) the name of each proposed bona fide purchaser or other transferee (“Proposed Transferee”); (iii) the number of Offered Shares to be transferred to each Proposed Transferee; (iv) the bona
fide cash price or other consideration for which the Holder proposes to transfer the Offered Shares (the “Offered Price”); and (v) that the Holder will offer to sell the Offered Shares to the Company and/or its assignee(s)
at the Offered Price as provided in this Section. 
 9.2 Exercise of Right of First Refusal. At any time
within thirty (30) days after the date of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase the Offered Shares proposed to be transferred to any one or more of the Proposed Transferees
named in the Notice, at the purchase price determined as specified below. 
 9.3 Purchase Price. The purchase price for the
Offered Shares purchased under this Section will be the Offered Price. If the Offered Price includes consideration other than cash, then the cash equivalent value of the non-cash consideration shall conclusively be deemed to be the value of such
non-cash consideration as determined in good faith by the Company’s Board of Directors. 
 9.4 Payment. Payment of the purchase
price for the Offered Shares will be payable, at the option of the Company and/or its assignee(s) (as applicable), by check or by cancellation of all or a portion of any outstanding indebtedness of the Holder to the Company (or to such assignee, in

 
the case of a purchase of Offered Shares by such assignee) or by any combination thereof. The purchase price will be paid without interest within sixty
(60) days after the Company’s receipt of the Notice, or, at the option of the Company and/or its assignee(s), in the manner and at the time(s) set forth in the Notice. 
 9.5 Holder’s Right to Transfer. If all of the Offered Shares proposed in the Notice to be transferred to a given Proposed
Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Offered Shares to that Proposed Transferee at the Offered Price or at a higher price, provided
that such sale or other transfer is consummated within 120 days after the date of the Notice, and provided further, that (i) any such sale or other transfer is effected in compliance with all applicable securities laws and
(ii) the Proposed Transferee agrees in writing that the provisions of this Section will continue to apply to the Offered Shares in the hands of such Proposed Transferee. If the Offered Shares described in the Notice are not transferred to the
Proposed Transferee within such 120 day period, then a new Notice must be given to the Company, and the Company will again be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 

9.6 Exempt Transfers. Notwithstanding anything to the contrary in this Section, the following transfers of Vested Shares will be exempt
from the Right of First Refusal: (i) the transfer of any or all of the Vested Shares during Purchaser’s lifetime by gift or on Purchaser’s death by will or intestacy to Purchaser’s “immediate family” (as defined below)
or to a trust for the benefit of Purchaser or Purchaser’s immediate family, provided that each transferee or other recipient agrees in a writing satisfactory to the Company that the provisions of this Section will continue to apply to the
transferred Vested Shares in the hands of such transferee or other recipient; (ii) any transfer of Vested Shares made pursuant to a statutory merger or statutory consolidation of the Company with or into another corporation or corporations
(except that the Right of First Refusal will continue to apply thereafter to such Vested Shares, in which case the surviving corporation of such merger or consolidation shall succeed to the rights of the Company under this Section unless the
agreement of merger or consolidation expressly otherwise provides); or (iii) any transfer of Vested Shares pursuant to the winding up and dissolution of the Company. As used herein, the term “immediate family” will mean
Purchaser’s spouse, the lineal descendant or antecedent, father, mother, brother or sister, child, adopted child, grandchild or adopted grandchild of the Purchaser or the Purchaser’s spouse, or the spouse of any child, adopted child,
grandchild or adopted grandchild of Purchaser or the Purchaser’s spouse. 
 9.7 Termination of Right of First Refusal. The
Company’s Right of First Refusal will terminate upon the Company’s initial public offering of Common Stock pursuant to an effective registration statement filed under the U.S. Securities Act of 1933, as amended. 
 10. Rights as Shareholder. Subject to the terms and conditions of this Exercise Agreement, Purchaser will have all of the rights
of a shareholder of the Company with respect to the Shares from and after the date that Shares are issued to Purchaser until such time as Purchaser disposes of the Shares or the Company and/or its assignee(s) exercise(s) the Repurchase Option or
Right of First Refusal. Upon an exercise of the Repurchase Option or the Right of First Refusal, Purchaser will have no further rights as a holder of the Shares so purchased upon such exercise, except the right to receive payment for the Shares so
purchased in accordance with the provisions of this Exercise Agreement, and Purchaser will promptly surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation. 
 11. Escrow. As security for Purchaser’s faithful performance of this Agreement, Purchaser agrees, immediately upon receipt of the
stock certificate(s) evidencing the Shares, to deliver such certificate(s), together with the Stock Powers executed by Purchaser and by Purchaser’s spouse, if 

 
any (with the date and number of Shares left blank), to the Secretary of the Company or other designee of the Company
(“Escrow Holder”), who is hereby appointed to hold such certificate(s) and Stock Powers in escrow and to take all such actions and to effectuate all such transfers and/or releases of such Shares as are in accordance with the
terms of this Agreement. Purchaser and the Company agree that Escrow Holder will not be liable to any party to this Exercise Agreement (or to any other party) for any actions or omissions unless Escrow Holder is grossly negligent or intentionally
fraudulent in carrying out the duties of Escrow Holder under this Exercise Agreement. Escrow Holder may rely upon any letter, notice or other document executed by any signature purported to be genuine and may rely on the advice of counsel and obey
any order of any court with respect to the transactions contemplated by this Agreement. The Shares will be released from escrow upon termination of both the Repurchase Option and the Right of First Refusal. 
 12. Restrictive Legends and Stop-Transfer Orders. 
 12.1 Legends. Purchaser understands and agrees that the Company will place the legends set forth below or similar legends on any stock
certificate(s) evidencing the Shares, together with any other legends that may be required by state or federal securities laws, the Company’s Articles of Incorporation or Bylaws, any other agreement between Purchaser and the Company or any
agreement between Purchaser and any third party: 
 THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
1933, AS AMENDED (THE “SECURITIES ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER
THE SECURITIES ACT AND APPLICABLE STATE SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER
OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES LAWS. THE SHARES
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN RESTRICTIONS ON PUBLIC RESALE AND TRANSFER, RIGHT OF REPURCHASE AND RIGHT OF FIRST REFUSAL OPTIONS HELD BY THE ISSUER AND/OR ITS ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION EXERCISE AGREEMENT
BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH PUBLIC SALE AND TRANSFER RESTRICTIONS AND THE RIGHT OF REPURCHASE AND RIGHT OF FIRST REFUSAL ARE BINDING ON
TRANSFEREES OF THESE SHARES. 
 12.2 Stop-Transfer Instructions. Purchaser agrees that, to ensure compliance with the
restrictions imposed by this Agreement, the Company may issue appropriate “stop-transfer” instructions to its transfer agent, if any, and if the Company transfers its own securities, it may make appropriate notations to the same effect in
its own records. 

 12.3 Refusal to Transfer. The Company will not be required (i) to transfer on its
books any Shares that have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares, or to accord the right to vote or pay dividends to any purchaser or other transferee
to whom such Shares have been so transferred. 
 13. Tax Consequences. PURCHASER UNDERSTANDS THAT PURCHASER MAY SUFFER
ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER’S PURCHASE OR DISPOSITION OF THE SHARES. PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH ANY TAX ADVISER PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR DISPOSITION OF THE
SHARES AND THAT PURCHASER IS NOT RELYING ON THE COMPANY FOR ANY TAX ADVICE. IN PARTICULAR, IF THE UNVESTED SHARES ARE SUBJECT TO REPURCHASE BY THE COMPANY, PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH PURCHASER’S TAX ADVISER
CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION WITH THE INTERNAL REVENUE SERVICE. Set forth below is a brief summary as of the date the Plan was adopted by the Board of some of the federal and California tax consequences of exercise of the
Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. PURCHASER SHOULD CONSULT A TAX ADVISER BEFORE EXECUTING THIS OPTION OR DISPOSING OF THE SHARES. 
 13.1 Exercise of Incentive Stock Option. If the Option qualifies as an incentive stock option, there will be no regular
federal income tax liability or California income tax liability upon the exercise of the Option, although the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price will be treated as a tax preference
item for federal alternative minimum tax purposes and may subject Purchaser to the alternative minimum tax in the year of exercise. 
 13.2
Exercise of Nonqualified Stock Option. If the Option does not qualify as an incentive stock option, there may be a regular federal income tax liability and a California income tax liability upon the exercise of the Option.
Purchaser will be treated as having received compensation income (taxable at ordinary income tax rates) equal to the excess, if any, of the Fair Market Value of the Shares on the date of exercise over the Exercise Price. If Purchaser is or was an
employee of the Company, the Company will be required to withhold from Purchaser’s compensation or collect from Purchaser and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of
exercise. 
 13.3 Disposition of Shares. The following tax consequences may apply upon disposition of Shares. 
 a. ISOs. If the Shares are held for more than twelve (12) months after the date of the transfer of the Shares pursuant to the exercise of an
ISO and are disposed of more than two years after the Date of Grant, any gain realized on disposition of the Shares will be treated as capital gain for federal and California income tax purposes. If Shares purchased under an ISO are disposed of
within the applicable one year or two year period, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the excess, if any, of the Fair Market Value of the Shares on the
date of exercise over the Exercise Price. 
 b. Nonqualified Stock Options. If the Shares are held for more than twelve
(12) months after the date of the transfer of the Shares pursuant to the exercise of a Nonqualified Stock Option, any gain realized on disposition of the Shares will be treated as Long-Term Capital Gain. 

 c. Withholding. The Company may be required to withhold from Participant’s compensation or
collect from Participant and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. 
 13.4. Section 83(b) Election for Unvested Shares. With respect to Unvested Shares, which are subject to the Repurchase Option, unless an election is filed by the Purchaser with the Internal Revenue Service
(and, if necessary, the proper state taxing authorities), within 30 days of the purchase of the Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar state tax provisions, if applicable) to be taxed currently on
any difference between the Exercise Price of the Unvested Shares and their Fair Market Value on the date of purchase, there may be a recognition of taxable income (including, where applicable, alternative minimum taxable income) to the Purchaser,
measured by the excess, if any, of the Fair Market Value of the Unvested Shares at the time they cease to be Unvested Shares, over the Exercise Price of the Unvested Shares. 
 14. Compliance with Laws and Regulations. The issuance and transfer of the Shares will be subject to and conditioned
upon compliance by the Company and Purchaser with all applicable state and federal laws and regulations and with all applicable requirements of any stock exchange or automated quotation system on which the Company’s Common Stock may be listed
or quoted at the time of such issuance or transfer. 
 15. Successors and Assigns. The Company may assign any of its
rights under this Agreement, including its rights to repurchase Shares under the Repurchase Option and the Right of First Refusal. This Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to
the restrictions on transfer herein set forth, this Agreement will be binding upon Purchaser and Purchaser’s heirs, executors, administrators, legal representatives, successors and assigns. 
 16. Governing Law; Severability. This Agreement shall be governed by and construed in accordance with the internal laws of the
State of California as such laws are applied to agreements between California residents entered into and to be performed entirely within California. If any provision of this Agreement is determined by a court of law to be illegal or unenforceable,
then such provision will be enforced to the maximum extent possible and the other provisions will remain fully effective and enforceable. 
 17. Notices. Any notice required to be given or delivered to the Company shall be in writing and addressed to the Corporate Secretary of the Company at its principal corporate offices. Any notice required to be given or
delivered to Purchaser shall be in writing and addressed to Purchaser at the address indicated above or to such other address as Purchaser may designate in writing from time to time to the Company. All notices shall be deemed effectively given upon
personal delivery, three (3) days after deposit in the United States mail by certified or registered mail (return receipt requested), one (1) business day after its deposit with any return receipt express courier (prepaid), or one
(1) business day after transmission by rapifax or telecopier. 
 18. Further Instruments. The parties agree to
execute such further instruments and to take such further action as may be reasonably necessary to carry out the purposes and intent of this Agreement. 

 19. Headings. The captions and headings of this Agreement are included for ease of
reference only and will be disregarded in interpreting or construing this Agreement. All references herein to Sections will refer to Sections of this Agreement. 
 20. Entire Agreement. The Plan, the Stock Option Agreement and this Exercise Agreement, together with all its Exhibits, constitute the entire agreement and understanding of the parties with respect
to the subject matter of this Agreement, and supersede all prior understandings and agreements, whether oral or written, between the parties hereto with respect to the specific subject matter hereof. 
 IN WITNESS WHEREOF, the Company has caused this Agreement to be executed in triplicate by its duly authorized representative and Purchaser has executed
this Agreement in triplicate as of the Effective Date.
