2007 Stock Option Plan and forms of stock option agreement

 Exhibit 10.3 
 BRONCUS TECHNOLOGIES, INC. 
 2007 STOCK OPTION PLAN 
 Adopted by the Board on May 4, 2007 and amended through September 25, 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 6,093,919*. In addition, following the Effective Date (as
defined in Section 17), any Shares issued under the Company’s 1997 Stock Option Plan, as amended (the “Prior Plan”) that are forfeited or repurchased by the Company prior to vesting or that are issuable upon
exercise of options granted pursuant to the Prior Plan that expire or become unexercisable for any reason without having been exercised in full, will no longer be available for grant and issuance under the Prior Plan, but will be available for grant
and issuance under this Plan*. 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; 

	*	As of September 24, 2007, an additional 35,187 shares are reserved and available for grant pursuant to this Plan due to forfeiture, repurchase or otherwise unexercisable under the
Prior Plan. 

	 	(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. When permitted by applicable law, 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, and when required by applicable law, Participants who are non-officer
employees 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. 

 5.4 Exercise Price. The Exercise Price of an Option will be determined by the Committee when
the Option is granted and when required by applicable law 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 when required by applicable law, 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 when required by applicable law, 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. 

 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. To the extent required by the Code, ISOs may only be granted under the Plan during the ten-year period measured from the earlier of: (a) the date the Plan was approved by the Board; and (b) the date the Plan was
approved by the Company’s shareholders. In addition, no more than 20,000,000 Shares shall be issued pursuant to the exercise of ISOs. 
 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 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 

	 	(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 any tax withholding
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 applicable tax
withholding 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. To the extent required by applicable law, 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. 
 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. For the benefit of the Company and/or its assignee(s) the Committee may, in its sole discretion, reserve 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, 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 Shares were issued pursuant to exercise of an Option granted to a Participant who is a non-officer employee 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. The Committee may, in its sole discretion, provide rights for the recovery of Shares that are more
liberal (or restrictive) than the foregoing, in relation to Options granted to persons other than non-officer employees or Options that the Committee has determined that applicable law does not impose such restrictions on rights to recover Shares
held by non-officer employees. 
 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. Options granted under this Plan are intended to comply with Section 25102(o) of the California Corporations Code, unless the Committee has expressly determined
that the provisions of such Option are intended to comply with another of the exemptions from California’s securities qualification requirements. Excepting when the Committee has expressly determined that the provisions of such Option are
intended to comply with another of the exemptions from California’s securities qualification requirements, any provision of an Option (or of the Plan) which is inconsistent with Section 25102(o) shall, without further act or amendment by
the Company or the Board, be reformed (limited to when being applied to such Option in the case of a reformation of a provision of the Plan) 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 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. 
 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 automatically be canceled (and any issuances of Shares rescinded) to the extent then required by applicable law.

 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.

 Type of Stock Option 
  

					
	(Check one):	  	[    ] Incentive Stock Option	  	
		  	[    ] Nonqualified Stock Option	  	

 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 (subject to a 6-month delay on such exercisability if granted to an employee whose pay constitutes wages rather than salary) 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 one-fourth ( 1/4th) of the Shares on             , (the “First Vesting Date”) and
thereafter on the      day of each 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. 
 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 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; 

  

 2 

	 	(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 a requirement for compliance 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) then in effect. 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 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. 
  

 3 

 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. The maximum federal tax rate on capital gain is 15%
for shares held for more than twelve (12) months (“Long-Term Capital Gain”). 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. 
 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. 
  

 4 

 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. 
 10.6 PARTICIPANT ACKNOWLEDGES THAT PARTICIPANT IS NOT RELYING ON THE COMPANY OR
ITS REPRESENTATIVES FOR TAX OR LEGAL ADVICE, AND THAT THE FOREGOING SUMMARY IS NECESSARILY INCOMPLETE AND SUBJECT TO CHANGE. THE PARTICIPANT IS ADVISED TO CONSULT WITH A TAX ADVISOR WITH RESPECT TO THE TAX CONSEQUENCES OF RECEIVING OR EXERCISING THE
OPTIONS AS WELL AS A LATER SALE OF SHARES. 
 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. 
 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. 
  

 5 

 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.

 3. 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. 
 3.5 No General Solicitation. At no time was Purchaser presented with or
solicited by any publicly issued or circulated newspaper, mail, radio, television or other form of general advertising or 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 the requirements of Section 25102(o) that are then in effect shall, without further act or amendment
by the Company or the 

  

 3 

 
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 the
SEC’s Rule 144 (promulgated under the Securities Act) which regulates sales of unregistered securities by non-issuers, presently requires that the Shares be held for a minimum holding period (which varies depending on whether Purchaser is an
“affiliate” (as defined in Rule 144) of the Company) 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. 
 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 

  

 4 

 
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 

  

 5 

 
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. 
  

 6 

 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” has the meaning given “Family Member” under Rule 701 (promulgated under the Securities Act) in relation to Purchaser. 
 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 

  

 7 

 
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 

  

 8 

 
THAT PURCHASER HAS CONSULTED WITH PURCHASER’S TAX ADVISER CONCERNING THE ADVISABILITY OF FILING AN 83(b) ELECTION WITH THE INTERNAL REVENUE SERVICE.

 13.1. 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. 
  

 9 

 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.

 Exhibit 10.6 
 [DATE] 
 [Name of Employee]

 [Address] 
 Re: Vesting Acceleration on
Acquisition - Amendment of Option Agreements. 
 Dear
                    : 
 The Board
of Directors of Broncus Technologies, Inc. (the “Company”) at its September, 2001 meeting, undertook a review of its policies regarding employee equity compensation in connection with any possible acquisition of the Company.
Based on that review and in order to provide its employees with appropriate equity compensation in the event that they are terminated in connection with an acquisition, the Board has concluded that all existing and future stock option agreements
with certain employees under the Company’s 1997 Stock Option Plan (each an “Option Agreement”) should be amended to provide employees with a specified amount of vesting acceleration in such a situation. 
 Summary of the Acceleration Amendment. 
 A description of the acceleration amendment is as follows. However, this description is only a summary and the actual terms shall be as set forth below under “Acceleration Amendment.” 
 As amended, each of your existing and any future Option Agreements that may be awarded to you will provide that, in the event that your employment is
terminated without cause (including poor performance) or you otherwise resign for certain specified reasons (all as described below) within 12 months after the Company is acquired, then vesting under each Option Agreement you have will automatically
accelerate so that the total percentage of vested shares will be equal to the sum of (i) 50% of all option shares, plus (ii) 50% of all option shares multiplied by a fraction, the numerator of which is the number of whole months that you
have been continuously employed by the Company (and the Company’s successor, if applicable) and the denominator of which is 48 months, all on the terms and conditions set forth in more detail below. Such vesting acceleration will also be
automatically provided in the event that the corporation that acquires the Company elects not to assume or otherwise substitute equivalent options for the Option Agreement. 
 An example of the operation of this accelerated vesting is as follows: Assume that an employee who was hired on January 1, 2001 has an option
exercisable for a total of 10,000 shares, the Company is acquired on November 30, 2001 and the employee is terminated without cause on February 28, 2002. In that hypothetical case, 14 months would have passed from the date that the
employee was hired until his/her termination. Without vesting acceleration, the option would (assuming vesting commenced effective 

 
as of the employee’s hire date) be vested as to 2,916 of the original 10,000 shares (14/48ths (29.16%) of 10,000 = 2,916). However, as a result of
the vesting acceleration provided for here (and in lieu of regular vesting) the option will instead be vested upon termination as to 6,458 shares (i.e., (50% x 10,000) + (14/48 x (50% x 10,000)) = 6,458). 
 Acceleration Amendment 
 In order to
implement the foregoing, each existing Option Agreement you have and any future Option Agreements that may be awarded to you are hereby amended to provide that, in the event that (i) you are “Terminated” (as defined below) or
“Resign for a Specified Reason” (as defined below) within twelve (12) months after a “Corporate Transaction” (as defined below), or (ii) the successor entity of any such “Corporate Transaction” or its parent
fails to assume the Option Agreement or substitute a similar option, then in lieu of the existing vesting provided for in the Option Agreement, the aggregate total number of shares issued and issuable under the Option Agreement that are vested and
exercisable shall automatically be accelerated to a number that is equal to (50% x A) + [(B / 48) x (50% x A)]. 
 For purposes of the
foregoing formula: 
  

					
	A	  	=	  	The total number of shares originally issuable upon exercise in full of the Option Agreement on the date it was granted (as such number may be adjusted for any subsequent stock splits,
reverse stock splits, stock dividends, or like events).
			
	B	  	=	  	The total number of full months that you have been continuously employed by the Company (including any successor of the Company following the Corporate Transaction).

 As used herein, a “Corporate Transaction” means (i) a consolidation,
merger, reorganization or other transaction or series of related transactions involving the Company in which the holders of the Company’s outstanding voting stock immediately prior to such transaction or series of related transactions own,
immediately after such transaction or series of related transactions, securities representing less than fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction or series of related transactions, as
a result of voting stock of the Company held by them immediately prior to such transaction or series of related transactions (excluding any transaction whose primary purpose is to raise funds for the Company through the sale of stock or other
securities), (ii) a dissolution or liquidation of the Company, or (iii) the sale of substantially all of the assets of the Company. 
 As used herein, “Terminated” means a termination of your employment for any reason other than (1) “Cause” (as defined in the 1997 Stock Option 

 
Plan that was provided to you with your Option Agreement), or (2) because your job performance is below the level of performance reasonably expected by
your employer for your position (as determined by your employer in good faith). “Terminated” does not include your employment merely being transferred to any parent, subsidiary or affiliate of the corporation employing you.

 As used herein, “Resign for a Specified Reason” means a voluntary resignation by you as a result of (and within
thirty (30) days of) being notified by the Company, the successor corporation or its parent of (1) a material reduction in your base salary from your base salary prior to the Corporate Transaction, or (2) of a relocation of the
Company’s offices that you are required to work at to a location more than thirty (30) miles from the Company’s principal offices immediately prior to the closing of the Corporate Transaction. 
 Please sign below where indicated to confirm your acceptance of the foregoing amendment to each existing and any future Option Agreement held by you. By
signing below, you and the Company also agree that: 
 (a) Other than as expressly amended in this letter agreement, the terms and conditions
of each Option Agreement remain in full force and effect. 
 (b) This letter, together with each Option Agreement held by you (or that may be
awarded to you in the future) and the “Plan” (as defined in the Option Agreement) sets forth the entire agreement of the parties with respect to the subject matter hereof and supercedes any and all prior agreements and undertakings with
respect to the subject matter hereof.
