 EXHIBIT 4.6 
 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE AND DISTRIBUTION THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED
(THE “SECURITIES ACT”) OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY THAT SUCH REGISTRATION
IS NOT REQUIRED DUE TO AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 
 WARRANT TO PURCHASE 
 SHARES OF SERIES E PREFERRED STOCK OF 
 EMPHASYS
MEDICAL, INC. 
 (Void after January 31, 2015) 
 This certifies that VENTURE LENDING & LEASING V, LLC, a Delaware limited liability company, or assigns (“Holder”), for value received, is entitled to purchase from EMPHASYS MEDICAL, INC., a Delaware corporation
(“Company”), the Applicable Number of fully paid and nonassessable shares of Company’s Series E Preferred Stock or Next Round Shares, as such term is defined below (the “Preferred Stock”), at a price equal to
the Stock Purchase Price (as hereinafter defined). Holder may also exercise this Warrant on a cashless or “net issuance” basis as described in Section 1(b) below. This Warrant is being issued in connection with the Loan and Security
Agreement of even date herewith (as amended, restated and supplemented from time to time, the “Loan Agreement”) between the Company and Venture Lending & Leasing V, Inc., an affiliate of Holder
(“Lender”). Capitalized terms used herein and not otherwise defined in this Warrant shall have the meaning(s) ascribed to them in the Loan Agreement unless the context would otherwise require. 
 Additional defined terms for this Warrant. For purposes of this Warrant: 
 “IPO” means Company’s first underwritten public offering of its shares of Common Stock pursuant to an effective registration statement under the Securities Act of 1933, as amended. 
 “IPO Price” means the price per share to the public (prior to underwriting discounts and commissions) in the Company’s IPO.

 “Next Round” means the next transaction after the Closing Date, other than an IPO, in which the Company issues and sells
a class or series of preferred stock in connection with a bona fide round of equity financing resulting in net aggregate proceeds to Company of at least $2,000,000. 
 “Next Round Price” means the lowest price per share paid by an investor in the Next Round for Next Round Shares. 
 “Next Round Shares” means the class or series of preferred stock of the Company issued and sold in the Next Round. 
 “Series E Price” means $2.40 per share. 
 The “Stock Purchase Price” shall
be determined as follows: 

	 	a)	If (i) a Change of Control occurs prior to either the Next Round or an IPO; or (ii) neither the Next Round nor an IPO closes prior to March 31, 2008, then the Stock
Purchase Price shall be the Series E Price. 

  

	 	b)	If the Next Round occurs prior to March 31, 2008 and precedes an IPO, then the Stock Purchase Price shall equal to the lesser of (i) the sum of Series E Price plus the
Next Round Price divided by 2, or (ii) the Series E Price multiplied by 1.5. 

  

	 	c)	if an IPO occurs prior to March 31, 2008 and precedes the Next Round, then the Stock Purchase Price shall equal to the lesser of (i) the sum of the Series E Price plus the
IPO Price divided by 2, or (ii) the Series E Price multiplied by 1.5. 

 The “Applicable Number” of
shares purchasable hereunder shall be the number obtained by dividing (A) the sum of (i) $412,500 and (ii) the product of (x) 0.045 and (y) the aggregate original principal amount of the Growth Capital Loans funded to the
Company by Lender under the Loan Agreement, by (B) the Stock Purchase Price. If in any case such number includes a fraction, the fraction shall be adjusted to the closest integral number. 
 As soon as reasonably practicable after the occurrence or non-occurrence of the latest event or condition necessary to fully determine the Stock Purchase Price and the
Applicable Number, the Company shall execute and deliver a supplement to this Warrant in substantially the form of Exhibit “A” attached hereto, completed with such quantity and price terms and other information as have been
determined as a result of the occurrence or non-occurrence of such events or conditions. The provisions of such supplement, once completed and executed, shall control the interpretation and exercise of this Warrant; provided, however, that
the failure of the Company to deliver such supplement shall not affect the rights of Holder to receive the Applicable Number of shares of the Preferred Stock at the Stock Purchase Price as set forth herein. 
 This Warrant may be exercised at any time and from time to time up to and including 5:00 p.m. (Pacific time) on January 30, 2015 (the
“Expiration Date”), upon surrender to the Company at its principal office at 700 Chesapeake Drive, Redwood City, CA 94063 (or at such other location as the Company may advise Holder in writing) of this Warrant properly endorsed with
the Form of Subscription attached hereto duly completed and signed and upon payment in cash or by check of the aggregate Stock Purchase Price for the number of shares of Exercise Stock for which this Warrant is being exercised determined in
accordance with the provisions hereof. The Stock Purchase Price and the number of shares purchasable hereunder are subject to further adjustment as provided in Section 4 of this Warrant. 
 This Warrant is subject to the following terms and conditions: 
 1. Exercise; Issuance of Certificates; Payment for Shares. 
 (a) Unless an election is made pursuant
to clause (b) of this Section 1, this Warrant shall be exercisable at the option of Holder, at any time or from time to time, on or before the Expiration Date for all or any portion of the shares of Preferred Stock (but not for a fraction
of a share) which may be purchased hereunder for the Stock Purchase Price multiplied by the number of shares to be purchased. In the event, however, that pursuant to Company’s Certificate of Incorporation, as amended, an event causing automatic
conversion of Company’s Preferred Stock shall have occurred prior to the exercise of this Warrant, in whole or in part, then this Warrant shall be exercisable for the number of shares of Common Stock of Company into which the Preferred Stock
not purchased upon any prior exercise of this Warrant would have been so converted (and, where the context requires, reference to “Preferred Stock” shall be deemed to be or include such Common Stock, as may be appropriate). Company agrees
that the shares of Preferred Stock purchased under this Warrant shall be and are deemed to be issued to Holder hereof as the record owner of such shares as of the close of business on the date on which the form of subscription shall have been
delivered and payment made for such shares. Subject to the provisions of Section 2, certificates for the shares of Preferred Stock so purchased, together with any other securities or property to which Holder hereof is entitled upon such
exercise, shall be delivered to Holder hereof by Company at Company’s expense within a reasonable time after the rights represented by this Warrant have been so exercised. Except as provided in clause (b)

  

 2 

 
of this Section 1, in case of a purchase of less than all the shares which may be purchased under this Warrant, Company shall cancel this Warrant and
execute and deliver a new Warrant or Warrants of like tenor for the balance of the shares purchasable under this Warrant surrendered upon such purchase to Holder hereof within a reasonable time. Each stock certificate so delivered shall be in such
denominations of Preferred Stock as may be requested by Holder hereof and shall be registered in the name of such Holder or such other name as shall be designated by such Holder, subject to the limitations contained in Section 2. 
 (b) Holder, in lieu of exercising this Warrant by the cash payment of the Stock Purchase Price pursuant to clause (a) of this Section 1, may
elect, at any time on or before the Expiration Date, to surrender this Warrant and receive that number of shares of Preferred Stock computed using the following formula: 
 

 
  

							
	 Where:
	  	X	  	=	  	the number of shares of Preferred Stock to be issued to Holder.
				
		  	Y	  	=	  	the number of shares of Preferred Stock that Holder would otherwise have been entitled to purchase hereunder pursuant to Section 1(a) (or such lesser number of shares as Holder may
designate in the case of a partial exercise of this Warrant).
				
		  	A	  	=	  	the Per Share Price (as defined in Section 1(c) below) of one (1) share of Preferred Stock at the time the net issuance election under this Section 1(b) is
made.
				
		  	B	  	=	  	the Stock Purchase Price then in effect.

 Election to exercise under this Section 1(b) may be made by delivering a signed form of subscription to
Company via facsimile, to be followed by delivery of this Warrant. 
 (c) For purposes of Section 1(b), “Per Share
Price” means: 
 (i) If this Warrant is exercised on the date of Company’s initial public offering of Common Stock, and if
Company’s registration statement relating to such public offering has been declared effective by the Securities and Exchange Commission, then the Per Share Price shall be the product of (A) the initial “Price to Public” of the
Common Stock specified in the final prospectus with respect to the offering, and (B) the number of shares of Common Stock into which each share of Preferred Stock exercised is convertible at the date of calculation. 
 (ii) If this Warrant is exercised after, and not on the date of Company’s initial public offering of Common Stock, and if Company’s Common
Stock is traded on a securities exchange or actively traded over-the-counter: 
 (1) If Company’s Common Stock is traded on a securities
exchange, the Per Share Price shall be deemed to be the product of (A) the closing price of Company’s Common Stock as listed on such exchange and as published in the Western Edition of The Wall Street Journal for the trading day
immediately prior to the date of Holder’s election hereunder and, (B) the number of shares of Common Stock into which each share of Preferred Stock exercised is convertible on such date. 
 (2) If Company’s Common Stock is actively traded over-the-counter, the Per Share Price shall be deemed to be the product of (A) the closing
bid or sales price, whichever is applicable, of Company’s Common Stock for the trading day immediately prior to the date of Holder’s election hereunder and (B) the number of shares of Common Stock into which each share of Preferred
Stock exercised is convertible on such date. 
  

 3 

 (iii) If neither (i) nor (ii) is applicable, the Per Share Price shall be determined in good
faith by the Board of Directors of Company based on relevant facts and circumstances at the time of the net exercise under Section 1(b), including in the case of a Change of Control (as defined in Section 4.3 hereof) the consideration
receivable by the holders of the Preferred Stock in such Change of Control and the liquidation preference (including any declared but unpaid dividends), if any, then applicable to the Preferred Stock. 
 2. Limitation on Transfer. 
 (a) This
Warrant and the Preferred Stock shall not be transferable except upon the conditions specified in this Section 2, which conditions are intended to ensure compliance with the provisions of the Securities Act. Holder or any holder of the
Preferred Stock issuable hereunder will cause any proposed transferee of the Warrant or Preferred Stock to agree to take and hold such securities subject to the provisions and upon the conditions specified in this Section 2. Notwithstanding the
foregoing and any other provision of this Section 2, Holder may freely transfer all or part of this Warrant or the shares issuable upon exercise of this Warrant (or the securities issuable, directly or indirectly, upon conversion of the shares,
if any) at any time to any lender transferee of a portion of the loan commitment of Lender under the Loan Agreement, by giving Company notice of the portion of the Warrant being transferred setting forth the name, address and taxpayer identification
number of the transferee and surrendering this warrant to Company for reissuance to the transferees(s) (and Holder, if applicable). 
 (b)
Each certificate representing (i) this Warrant, (ii) the Preferred Stock, (iii) shares of Company’s Common Stock issued upon conversion of the Preferred Stock and (iv) any other securities issued in respect to the Preferred
Stock or Common Stock issued upon conversion of the Preferred Stock upon any stock split, stock dividend, recapitalization, merger, consolidation or similar event, shall (unless otherwise permitted by the provisions of this Section 2 or unless
such securities have been registered under the Securities Act or sold under Rule 144) be stamped or otherwise imprinted with a legend substantially in the following form (in addition to any legend required under applicable state securities laws):

 THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE AND DISTRIBUTION
THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OR ANY STATE SECURITIES LAWS. SUCH SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL IN A FORM REASONABLY ACCEPTABLE TO THE COMPANY
THAT SUCH REGISTRATION IS NOT REQUIRED DUE TO AN EXEMPTION THEREFROM UNDER SAID ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 
 (c) Holder
and each person to whom this Warrant is subsequently transferred represents and warrants to Company (by acceptance of such transfer) that it is an “accredited investor” (as defined in Rule 501 of Regulation D under the Securities Act) and
that it will not transfer this Warrant (or securities issuable upon exercise hereof unless a registration statement under the Securities Act was in effect with respect to such securities at the time of issuance thereof) except pursuant to
(i) an effective registration statement under the Securities Act, (ii) Rule 144 under the Securities Act (or any other rule under the Securities Act relating to the disposition of securities), or (iii) an opinion of counsel,
reasonably satisfactory to counsel for Company, that an exemption from such registration is available. 
 3. Shares to be Fully Paid;
Reservation of Shares. Company covenants and agrees that all shares of Preferred Stock which may be issued upon the exercise of the rights represented by this Warrant will, upon issuance, be duly authorized, validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder and free of all taxes, liens and charges with respect to the issue thereof. Company further covenants and agrees that during the period within which the rights represented by this
Warrant may be exercised, Company will at all times have authorized and reserved, for the purpose of issue or transfer upon exercise of the subscription rights evidenced by this Warrant, a sufficient number of shares of authorized but unissued
Preferred Stock, or other 

  

 4 

 
securities and property, when and as required to provide for the exercise of the rights represented by this Warrant. Company will take all such action as may
be necessary to assure that such shares of Preferred Stock may be issued as provided herein without violation of any applicable law or regulation, or of any requirements of any domestic securities exchange upon which the Preferred Stock may be
listed. Company will not take any action which would result in any adjustment of the Stock Purchase Price (as described in Section 4 hereof) (i) if the total number of shares of Preferred Stock issuable after such action upon exercise of
all outstanding warrants, together with all shares of Preferred Stock then outstanding and all shares of Preferred Stock then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding, would exceed
the total number of shares of Preferred Stock then authorized by Company’s Certificate of Incorporation, (ii) if the total number of shares of Common Stock issuable after such action upon the conversion of all such shares of Preferred
Stock together with all shares of Common Stock then outstanding and then issuable upon exercise of all options and upon the conversion of all convertible securities then outstanding would exceed the total number of shares of Common Stock then
authorized by Company’s Certificate of Incorporation or (iii) if the par value per share of the Preferred Stock would exceed the Stock Purchase Price. 
 4. Adjustment of Stock Purchase Price and Number of Shares. The Stock Purchase Price and the number of shares purchasable upon the exercise of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events described in this Section 4. Upon each adjustment of the Stock Purchase Price, Holder shall thereafter be entitled to purchase, at the Stock Purchase Price resulting from such adjustment, the number of shares
obtained by multiplying the Stock Purchase Price in effect immediately prior to such adjustment by the number of shares purchasable pursuant hereto immediately prior to such adjustment, and dividing the product thereof by the Stock Purchase Price
resulting from such adjustment. 
 4.1 Subdivision or Combination of Stock. In case Company shall at any time subdivide its
outstanding shares of Preferred Stock into a greater number of shares, the Stock Purchase Price in effect immediately prior to such subdivision shall be proportionately reduced, and conversely, in case the outstanding shares of Preferred Stock of
Company shall be combined into a smaller number of shares, the Stock Purchase Price in effect immediately prior to such combination shall be proportionately increased. 
 4.2 Dividends in Preferred Stock, Other Stock, Property, Reclassification. If at any time or from time to time the holders of Preferred Stock (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received or become entitled to receive, without payment therefor, 
 (a) Preferred Stock, or
any shares of stock or other securities whether or not such securities are at any time directly or indirectly convertible into or exchangeable for Preferred Stock, or any rights or options to subscribe for, purchase or otherwise acquire any of the
foregoing by way of dividend or other distribution, 
 (b) any cash paid or payable otherwise than as a cash dividend, or 
 (c) Preferred Stock or other or additional stock or other securities or property (including cash) by way of spin off, split-up, reclassification,
combination of shares or similar corporate rearrangement, (other than shares of Preferred Stock issued as a stock split, adjustments in respect of which shall be covered by the terms of Section 4.1 above), 
 then and in each such case, Holder hereof shall, upon the exercise of this Warrant, be entitled to receive, in addition to the number of shares of Preferred Stock
receivable thereupon, and without payment of any additional consideration therefore, the amount of stock and other securities and property (including cash in the cases referred to in clauses (b) and (c) above) which such Holder would hold
on the date of such exercise had he been the holder of record of such Preferred Stock as of the date on which holders of Preferred Stock received or became entitled to receive such shares and/or all other additional stock and other securities and
property.

 4.3 Change of Control. 
 (a) If any capital reorganization of the capital stock of Company, or any consolidation or merger of Company with another entity, or the sale of all or
substantially all of its assets to another entity (each, a “Change of Control”) shall be effected in such a way that holders of Preferred Stock shall be entitled to receive stock, securities or assets with respect to or in exchange
for Preferred Stock, then subject to Section 4.3(b), as a condition of such Change of Control, lawful and adequate provisions shall be made whereby Holder hereof shall thereafter have the right to purchase and receive (in lieu of the shares of
the Preferred Stock of Company immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby) such shares of stock, securities or assets as may be issued or payable with respect to or in exchange for a number
of outstanding shares of such Preferred Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the rights represented hereby. In any such case, appropriate provision shall be made
with respect to the rights and interests of Holder to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Stock Purchase Price and of the number of shares purchasable and receivable upon the exercise
of this Warrant) shall thereafter be applicable, as nearly as may be possible, in relation to any shares of stock, securities or assets thereafter deliverable upon the exercise hereof. Except as set forth in Section 4.3(b), Company will not
effect any such Change of Control unless, prior to the consummation thereof, the successor corporation (if other than Company) resulting from such Change of Control agrees by written instrument, executed and mailed or delivered to the registered
Holder hereof at the last address of such Holder appearing on the books of Company, to assume the obligation to deliver to such Holder such shares of stock, securities or assets as, in accordance with the foregoing provisions, such Holder may be
entitled to purchase. 
 (b) Notwithstanding anything to the contrary set forth in Section 4.3(a), if (A) there is a Change of
Control which consists of an acquisition of the Company by another corporation where 100% of the consideration payable by the acquirer is cash distributable to the Company’s shareholders, or (B) there is a Change of Control that satisfies
the following five (5) criteria: (1) the consideration received by holders of the Preferred Stock (or the underlying Common Stock issuable upon conversion thereof) in such Change of Control is at least two and one-half (2.5) times the
then-effective Stock Purchase Price, (2) the consideration received by the Company’s stockholders in such Change of Control consists of cash, shares of stock that are of a publicly traded company listed on a national exchange, or a
combination of cash and shares of stock that are of a publicly traded company listed on a national exchange, (3) the shares (if any) receivable by Holder were Holder to exercise this Warrant in full as of immediately prior to the closing of
such Change in Control may be publicly re-sold by Holder in their entirety following the closing of such transaction pursuant to Rule 144 or an effective registration statement under the Securities Act, (4) the Company’s stockholders own
less than 50% of the voting securities of the acquiring, successor or surviving entity as of immediately following the closing of such Change in Control and (5) the acquiring, successor or surviving entity does not assume any then-outstanding
warrants of the Company, then Holder agrees that it shall exercise this Warrant, upon not less than five (5) days prior written notice to Holder, in accordance with the provisions of either Section 1(a) or Section 1(b) upon closing of
the Change of Control. 
 (c) Notwithstanding anything to the contrary set forth in Section 4.3(a), in the event of a Change of Control
other than one covered by Section 4.3(b), at Company’s sole option, Holder shall surrender this Warrant in exchange for a number of shares of Company’s securities, such number of shares being equal to the maximum number of shares
issuable pursuant to the terms hereof (after taking into account all adjustments described herein) had Holder elected to exercise this Warrant immediately prior to the closing of such Change of Control and purchased all such shares pursuant to the
cash exercise provision set forth in Section 1(a) hereof (as opposed to the cashless exercise provision set forth in Section 1(b)). Company acknowledges and agrees that Holder shall not be required to make any additional payment (cash
or otherwise) for such shares as further consideration for their issuance in exchange for Holder’s surrender of this Warrant pursuant to the terms of the preceding sentence. 
 4.4 Sale or Issuance Below Purchase Price; “Pay-to-Play” Exemption. 
  

 6 

 (a) The other antidilution rights applicable to the shares of Preferred Stock purchasable hereunder are
set forth in Company’s Certificate of Incorporation, as amended through the date hereof (the “Charter”). Such antidilution rights shall not be restated, amended, modified or waived in any manner without Holder’s prior
written consent if the effect of such restatement, amendment, modification or waiver on Holder hereof would be more adverse to Holder hereof than, and substantially dissimilar to, its effect on the other holders of the same series of Company’s
Preferred Stock. Company shall promptly provide Holder hereof with any restatement, amendment, modification or waiver of the Charter promptly after the same has been made. 
 (b) In the event that any “pay to play” terms or conditions (i.e. terms or conditions that require a holder of Company’s Preferred Stock
to purchase securities in a future round of equity financing or else lose the benefit of antidilution protection applicable to the shares of Preferred Stock issuable upon the exercise of this Warrant or have such shares of Preferred Stock
automatically convert to common stock or convert to another class and series of Company’s capital stock) in Company’s Charter, as amended from time to time, or other agreement among the Company and its stockholders are triggered in
connection with the consummation of a Down Round (hereinafter defined) or otherwise after the date hereof, then in such event, this Warrant shall automatically adjust to provide Holder with the same securities and/or rights that Holder would have
received had Holder participated in the Down Round to its full pro rata share with respect to the Preferred Stock issuable upon exercise of this Warrant (e.g., if this Warrant provides for the purchase of Series B Preferred Stock, and Company after
the date hereof consummates a Down Round in which those holders of Series B Preferred Stock who participate to their full pro rata share in such Down Round become entitled to exchange such Series B Preferred Stock for Series B-1 Preferred Stock and
those holders of Series B Preferred Stock who do not participate to their full pro rata share will have their Series B Preferred Stock converted into Common Stock, then this Warrant would automatically adjust to provide the right to purchase Series
B-1 Preferred Stock instead of Common Stock). “Down Round” means any non-public offering of equity securities of Company after the original date of issuance of this Warrant at a price per share lower than the Stock Purchase Price
then in effect. 
 4.5 Notice of Adjustment. Upon any adjustment of the Stock Purchase Price, and/or any increase or decrease in the
number of shares purchasable upon the exercise of this Warrant Company shall give written notice thereof, by first class mail, postage prepaid, addressed to Holder at the address of Holder as shown on the books of Company. The notice, which may be
substantially in the form of Exhibit “A” attached hereto, shall be signed by Company’s chief financial officer and shall state the Stock Purchase Price resulting from such adjustment and the increase or decrease, if any, in the
number of shares purchasable at such price upon the exercise of this Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. 
 4.6 Other Notices. If at any time: 
 (a) Company shall declare any cash dividend upon its Preferred Stock; 
 (b) Company shall declare any dividend upon its Preferred
Stock payable in stock or make any special dividend or other distribution to the holders of its Preferred Stock; 
 (c) Company shall offer
for subscription pro rata to the holders of its Preferred Stock any additional shares of stock in connection with a Down Round or additional shares of stock of any class or other rights; 
 (d) there shall be any capital reorganization or reclassification of the capital stock of Company, or consolidation or merger of Company with, or sale
of all or substantially all of its assets to, another entity; 
  

 7 

 (e) there shall be a voluntary or involuntary dissolution, liquidation or winding-up of Company; or

 (f) Company shall take or propose to take any other action, notice of which is actually provided to holders of the Preferred Stock;

 then, in any one or more of said cases, Company shall give, by first class mail, postage prepaid, addressed to Holder of this Warrant at the address of
such Holder as shown on the books of Company, (i) at least 20 days’ prior written notice of the date on which the books of Company shall close or a record shall be taken for such dividend, distribution or subscription rights or for
determining rights to vote in respect of any such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or winding-up, or other action and (ii) in the case of any such reorganization, reclassification,
consolidation, merger, sale, dissolution, liquidation or winding-up, or other action, at least 20 days’ written notice of the date when the same shall take place. Any notice given in accordance with the foregoing clause (i) shall also
specify, in the case of any such dividend, distribution or subscription rights, the date on which the holders of Preferred Stock shall be entitled thereto. Any notice given in accordance with the foregoing clause (ii) shall also specify the
date on which the holders of Preferred Stock shall be entitled to exchange their Preferred Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation or
winding-up, or other action as the case may be. 
 4.7 Certain Events. If any change in the outstanding Preferred Stock of Company or
any other event occurs as to which the other provisions of this Section 4 are not strictly applicable or if strictly applicable would not fairly effect the adjustments to this Warrant in accordance with the essential intent and principles of
such provisions, then the Board of Directors of Company shall make in good faith an adjustment in the number and class of shares issuable under this Warrant, the Stock Purchase Price and/or the application of such provisions, in accordance with such
essential intent and principles, so as to protect such purchase rights as aforesaid. The adjustment shall be such as will give Holder upon exercise for the same aggregate Stock Purchase Price the total number, class and kind of shares as Holder
would have owned had this Warrant been exercised prior to the event and had Holder continued to hold such shares until after the event requiring adjustment. 
 5. Issue Tax. The issuance of certificates for shares of Preferred Stock upon the exercise of this Warrant shall be made without charge to Holder for any issue tax in respect thereof; provided, however, that
Company shall not be required to pay any tax which may be payable in respect of any transfer involved in the issuance and delivery of any certificate in a name other than that of Holder being exercised. 
 6. Closing of Books. Company will at no time close its transfer books against the transfer of this Warrant or of any shares of Preferred Stock
issued or issuable upon the exercise of this Warrant in any manner which interferes with the timely exercise of this Warrant. 
 7. No
Voting or Dividend Rights; Limitation of Liability. Nothing contained in this Warrant shall be construed as conferring upon Holder hereof the right to vote or to consent as a stockholder in respect of meetings of stockholders for the election of
directors of Company or any other matters or any rights whatsoever as a stockholder of Company. No dividends or interest shall be payable or accrued in respect of this Warrant or the interest represented hereby or the shares purchasable hereunder
until, and only to the extent that, this Warrant shall have been exercised. No provisions hereof, in the absence of affirmative action by Holder to purchase shares of Preferred Stock, and no mere enumeration herein of the rights or privileges of
Holder hereof, shall give rise to any liability of such Holder for the Stock Purchase Price or as a stockholder of Company, whether such liability is asserted by Company or by its creditors. 
 8. Intentionally Omitted. 
  

 8 

 9. Registration Rights. The Fourth Amended and Restated Investors’ Rights Agreement dated as
of June 29, 2006 (the “Rights Agreement”) shall be amended to grant certain registration rights as set forth in the Amendment to Fourth Amended and Restated Investors’ Rights Agreement in substantially the form attached
hereto as Exhibit C. 
 10. Rights and Obligations Survive Exercise of Warrant. The rights and obligations of Company, of
Holder and of the holder of shares of Preferred Stock issued upon exercise of this Warrant, contained in Sections 6 and 9 shall survive the exercise of this Warrant. 
 11. Modification and Waiver. This Warrant and any provision hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the party against which enforcement of the same is
sought. 
 12. Notices. Any notice, request or other document required or permitted to be given or delivered to Holder hereof or
Company shall be deemed to have been given (i) upon receipt if delivered personally or by courier (ii) upon confirmation of receipt if by telecopy or (iii) three business days after deposit in the US mail, with postage prepaid and
certified or registered, to each such Holder at its address as shown on the books of Company or to Company at the address indicated therefor in the first paragraph of this Warrant. 
 13. Binding Effect on Successors. Subject to Section 4.3, this Warrant shall be binding upon any corporation succeeding Company by merger,
consolidation or acquisition of all or substantially all of Company’s assets. All of the obligations of Company relating to the Preferred Stock issuable upon the exercise of this Warrant shall survive the exercise and termination of this
Warrant. All of the covenants and agreements of Company shall inure to the benefit of the successors and assigns of Holder hereof. Company will, at the time of the exercise of this Warrant, in whole or in part, upon request of Holder hereof but at
Company’s expense, acknowledge in writing its continuing obligation to Holder hereof in respect of any rights (including, without limitation, any right to registration of the shares of Common Stock) to which Holder hereof shall continue to be
entitled after such exercise in accordance with this Warrant; provided, that the failure of Holder hereof to make any such request shall not affect the continuing obligation of Company to Holder hereof in respect of such rights. 
 14. Descriptive Headings and Governing Law. The descriptive headings of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. This Warrant shall be construed and enforced in accordance with, and the rights of the parties shall be governed by, the laws of the State of California. 
 15. Lost Warrants or Stock Certificates. Company represents and warrants to Holder hereof that upon receipt of evidence reasonably satisfactory to
Company of the loss, theft, destruction, or mutilation of any Warrant or stock certificate and, in the case of any such loss, theft or destruction, upon receipt of an indemnity reasonably satisfactory to Company, or in the case of any such
mutilation upon surrender and cancellation of such Warrant or stock certificate, Company at its expense will make and deliver a new Warrant or stock certificate, of like tenor, in lieu of the lost, stolen, destroyed or mutilated Warrant or stock
certificate provided, however, that, if the Company’s stock is publicly traded, the Company may require the posting of a bond in an amount and nature as is customary and reasonable given the circumstances. 
 16. Fractional Shares. No fractional shares shall be issued upon exercise of this Warrant. Company shall, in lieu of issuing any fractional share,
pay the holder entitled to such fraction a sum in cash equal to such fraction multiplied by the then effective Stock Purchase Price. 
 17.
Representations of Holder. With respect to this Warrant, Holder represents and warrants to Company as follows:

constructions, interpretations and decisions shall be final and binding on all Participants;

 (xii) in order to fulfill the purposes of the Plan and without amending the Plan, to modify grants of Options or Stock Purchase Rights to Participants
who are foreign nationals or employed outside of the United States in order to recognize differences in local law, tax policies or customs. 
 5. Eligibility. 
 (a) Recipients of Grants. Nonstatutory Stock Options and Stock Purchase Rights may be
granted to Employees and Consultants. Incentive Stock Options may be granted only to Employees, provided that Employees of Affiliates shall not be eligible to receive Incentive Stock Options. 
 (b) Type of Option. Each Option shall be designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock
Option.

aggregate Fair Market Value of Shares with respect to which Options designated as Incentive Stock Options are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company or any Parent or Subsidiary)
exceeds $100,000, such excess Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 5(c), Incentive Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of
the Shares subject to an Incentive Stock Option shall be determined as of the date of the grant of such Option. 
 (d) No Employment
Rights. The Plan shall not confer upon any Participant any right with respect to continuation of an employment or consulting relationship with the Company, nor shall it interfere in any way with such Participant’s right or the

Agreement and provided further that, in the case of an Incentive Stock Option granted to a person who at the time of such grant is a Ten Percent Holder, the term of the Option shall be five years from the date of grant thereof or such shorter term
as may be provided in the Option Agreement. 
 8. Reserved. 
 9. Option Exercise Price and Consideration. 
 (a) Exercise Price. The per Share exercise price for the Shares to be issued pursuant to exercise of an Option shall be such price as is determined by the Administrator and set forth in the Option
Agreement, but shall be subject to the following: 
 (i) In the case of an Incentive Stock Option 
 (A) granted to an Employee who at the time of grant is a Ten Percent Holder, the per Share exercise price shall be no less than 110% of the Fair Market
Value per Share on the date of grant; or 
 (B) granted to any other Employee, the per Share exercise price shall be no less than 100% of
the Fair Market Value per Share on the date of grant. 
 (ii) In the case of a Nonstatutory Stock Option 
 (A) granted prior to the date, if any, on which the Common Stock becomes a Listed Security to a person who is at the time of grant is a Ten Percent
Holder, the per Share exercise price shall be no less than 110% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined by the Administrator;

 (B) granted prior to the date, if any, on which the Common Stock becomes a Listed Security to any other eligible person, the per Share
exercise price shall be no less than 85% of the Fair Market Value per Share on the date of grant if required by the Applicable Laws and, if not so required, shall be such price as is determined by the Administrator; or 
 (C) granted on or after the date, if any, on which the Common Stock becomes a Listed Security to any eligible person, the per share Exercise Price shall
be such price as determined by the Administrator provided that if such eligible person is, at the time of the grant of such Option, a Named Executive of the Company, the per share Exercise Price shall be no less than 100% of the Fair Market Value on
the date of grant if such Option is intended to qualify as performance-based compensation under Section 162(m) of the Code. 
  

 -7- 

 (iii) Notwithstanding the foregoing, Options may be granted with a per Share exercise price other than
as required above pursuant to a merger or other corporate transaction. 
 (b) Permissible Consideration. The consideration to
be paid for the Shares to be issued upon exercise of an Option, including the method of payment, shall be determined by the Administrator (and, in the case of an Incentive Stock Option, shall be determined at the time of grant) and may consist
entirely of (1) cash; (2) check; (3) delivery of Optionee’s promissory note with such recourse, interest, security and redemption provisions as the Administrator determines to be Emphasys Medical (subject to the provisions of
Section 153 of the Delaware General Corporation Law); (4) cancellation of indebtedness; (5) other Shares that have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Option
is exercised, provided that in the case of Shares acquired, directly or indirectly, from the Company, such Shares must have been owned by the Optionee for more than six months on the date of surrender (or such other period as may be required to
avoid the Company’s incurring an adverse accounting charge); (6) delivery of a properly executed exercise notice together with such other documentation as the Administrator and a securities broker approved by the Company shall require to
effect exercise of the Option and prompt delivery to the Company of the sale or loan proceeds required to pay the exercise price and any applicable withholding taxes; or (7) any combination of the foregoing methods of payment. In making its
determination as to the type of consideration to accept, the Administrator shall consider if acceptance of such consideration may be reasonably expected to benefit the Company and the Administrator may, in its sole discretion, refuse to accept a
particular form of consideration at the time of any Option exercise. 
 10. Exercise of Option. 
 (a) General. 
 (i)
Exercisability. Any Option granted hereunder shall be exercisable at such times and under such conditions as determined by the Administrator, consistent with the term of the Plan and reflected in the Option Agreement, including vesting
requirements and/or performance criteria with respect to the Company and/or the Optionee; provided however that, if required by the Applicable Laws, any Option granted prior to the date, if any, upon which the Common Stock becomes a Listed Security
shall become exercisable at the rate of at least 20% per year over five years from the date the Option is granted. In the event that any of the Shares issued upon exercise of an Option (which exercise occurs prior to the date, if any, upon
which the Common Stock becomes a Listed Security) should be subject to a right of repurchase in the Company’s favor, such repurchase right shall, if required by the Applicable Laws, lapse at the rate of at least 20% per year over five
years from the date the Option is granted. Notwithstanding the above, in the case of an Option granted to an officer, Director or Consultant of the Company or any Parent, Subsidiary or Affiliate of the Company, the Option may become fully
exercisable, or a repurchase right, if any, in favor of the Company shall lapse, at any time or during any 

  

 -8- 

 
period established by the Administrator. The Administrator shall have the discretion to determine whether and to what extent the vesting of Options shall be
tolled during any unpaid leave of absence; provided, however, that in the absence of such determination, vesting of Options shall be tolled during any such leave. 
 (ii) Minimum Exercise Requirements. An Option may not be exercised for a fraction of a Share. The Administrator may require that an Option be exercised as to a minimum number of Shares, provided that
such requirement shall not prevent an Optionee from exercising the full number of Shares as to which the Option is then exercisable. 
 (iii) Procedures for and Results of Exercise. An Option shall be deemed exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option by the person entitled to exercise
the Option and the Company has received full payment for the Shares with respect to which the Option is exercised. Full payment may, as authorized by the Administrator, consist of any consideration and method of payment allowable under
Section 9(b) of the Plan, provided that the Administrator may, in its sole discretion, refuse to accept any form of consideration at the time of any Option exercise. 
 Exercise of an Option in any manner shall result in a decrease in the number of Shares that thereafter may be available, both for purposes of the Plan and for sale under the Option, by the number of Shares as to which
the Option is exercised. 
 (iv) Rights as Stockholder. Until the issuance of the Shares (as evidenced by the Emphasys Medical
entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a stockholder shall exist with respect to the Optioned Stock, notwithstanding the exercise of the
Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the stock certificate is issued, except as provided in Section 14 of the Plan. 
 (b) Termination of Employment or Consulting Relationship. Except as otherwise set forth in this Section 10(b), the Administrator shall
establish and set forth in the applicable Option Agreement the terms and conditions upon which an Option shall remain exercisable, if at all, following termination of an Optionee’s Continuous Service Status, which provisions may be waived or
modified by the Administrator at any time. To the extent that the Optionee is not entitled to exercise an Option at the date of his or her termination of Continuous Service Status, or if the Optionee (or other person entitled to exercise the Option)
does not exercise the Option to the extent so entitled within the time specified in the Option Agreement or below (as applicable), the Option shall terminate and the Optioned Stock underlying the unexercised portion of the Option shall revert to the
Plan. In no event may any Option be exercised after the expiration of the Option term as set forth in the Option Agreement (and subject to Section 7). 
 The following provisions (1) shall apply to the extent an Option Agreement does not specify the terms and conditions upon which an Option shall terminate upon termination of an Optionee’s Continuous Service
Status, and (2) establish the minimum post-termination exercise periods that may be set forth in an Option Agreement: 
  

 -9- 

 (i) Termination other than Upon Disability or Death or for Cause. In the event of
termination of an Optionee’s Continuous Service Status, such Optionee may exercise an Option for 30 days following such termination to the extent the Optionee was entitled to exercise it at the date of such termination. No termination shall be
deemed to occur and this Section 10(b)(i) shall not apply if (i) the Optionee is a Consultant who becomes an Employee, or (ii) the Optionee is an Employee who becomes a Consultant. 
 (ii) Disability of Optionee. In the event of termination of an Optionee’s Continuous Service Status as a result of his or her
disability (including a disability within the meaning of Section 22(e)(3) of the Code), such Optionee may exercise an Option at any time within six months following such termination to the extent the Optionee was entitled to exercise it at the
date of such termination. 
 (iii) Death of Optionee. In the event of the death of an Optionee during the period of Continuous
Service Status since the date of grant of the Option, or within thirty days following termination of Optionee’s Continuous Service Status, the Option may be exercised by Optionee’s estate or by a person who acquired the right to exercise
the Option by bequest or inheritance at any time within twelve months following the date of death, but only to the extent of the right to exercise that had accrued at the date of death or, if earlier, the date the Optionee’s Continuous Service
Status terminated. 
 (iv) Termination for Cause. In the event of termination of an Optionee’s Continuous Service Status
for Cause, any Option (including any exercisable portion thereof) held by such Optionee shall immediately terminate in its entirety upon first notification to the Optionee of termination of the Optionee’s Continuous Service Status. If an
Optionee’s employment or consulting relationship with the Company is suspended pending an investigation of whether the Optionee shall be terminated for Cause, all the Optionee’s rights under any Option likewise shall be suspended during
the investigation period and the Optionee shall have no right to exercise any Option. This Section 10(b)(iv) shall apply with equal effect to vested Shares acquired upon exercise of an Option as follows: (A) with respect any
(1) Option granted to a Participant resident outside of the state of California at the time an Option is granted, whenever such grant date occurs, and (2) with respect to any Option granted to a Participant resident in California where the
grant date occurs on or after the date, if any, upon which the Common Stock becomes a Listed Security or granted to an officer, Director or Consultant resident in California prior to such date, the Company shall have a right to repurchase vested
Shares acquired upon exercise of an Option at any time within 90 days from termination of the Participant’s Continuous Service Status for Cause at the Participant’s original purchase price for the Shares; and (B) with respect to
Participants who are not officers, Directors or Consultants and who are resident in the state of California at the time an Option is granted where the grant date occurs prior to the date, if any, upon which the Common Stock becomes a Listed
Security, the Company shall have the right to repurchase such Shares from the Participant upon the following terms: (1) the repurchase shall be made within 90 days of termination of the Participant’s Continuous Service Status for Cause at
the Fair Market Value of the Shares as of the date of termination, (2) consideration for the repurchase shall consist of cash or cancellation of purchase money indebtedness, and (3) the repurchase right shall terminate upon the effective
date of the Company’s initial public offering of its Common Stock. 
  

 -10- 

 Nothing in this Section 10(b)(iv) shall in any way limit the Company’s right to purchase
unvested Shares issued upon exercise of an Option as set forth in the applicable Option Agreement. 
 (c) Buyout Provisions.
The Administrator may at any time offer to buy out for a payment in cash or Shares an Option previously granted under the Plan based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that
such offer is made. 
 11. Stock Purchase Rights. 
 (a) Rights to Purchase. When the Administrator determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree in writing of the terms, conditions and restrictions related
to the offer, including the number of Shares that such person shall be entitled to purchase, the price to be paid, and the time within which such person must accept such offer. In the case of a Stock Purchase Right granted prior to the date, if any,
on which the Common Stock becomes a Listed Security and if required by the Applicable Laws at that time, the purchase price of Shares subject to such Stock Purchase Rights shall not be less than 85% of the Fair Market Value of the Shares as of the
date of the offer, or, in the case of a Ten Percent Holder, the price shall not be less than 100% of the Fair Market Value of the Shares as of the date of the offer. If the Applicable Laws do not impose the requirements set forth in the preceding
sentence and with respect to any Stock Purchase Rights granted after the date, if any, on which the Common Stock becomes a Listed Security, the purchase price of Shares subject to Stock Purchase Rights shall be as determined by the Administrator.
The offer to purchase Shares subject to Stock Purchase Rights shall be accepted by execution of a Restricted Stock Purchase Agreement in the form determined by the Administrator. 
 (b) Repurchase Option. 
 (i)
General. Unless the Administrator determines otherwise, the Restricted Stock Purchase Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the purchaser’s employment
with the Company for any reason (including death or disability). The purchase price for Shares repurchased pursuant to the Restricted Stock Purchase Agreement shall be the original purchase price paid by the purchaser and may be paid by cancellation
of any indebtedness of the purchaser to the Company. The repurchase option shall lapse at such rate as the Administrator may determine, provided that with respect to a Stock Purchase Right granted prior to the date, if any, on which the Common Stock
becomes a Listed Security to a purchaser who is not an officer, Director or Consultant of the Company or of any Parent or Subsidiary of the Company, it shall lapse at a minimum rate of 20% per year if required by the Applicable Laws.

 (ii) Termination for Cause. In the event of termination of a Participant’s Continuous Service Status for Cause, the
Company shall have the right to repurchase from the Participant vested Shares issued upon exercise of a Stock Purchase Right as follows: (A) with respect any (1) Shares acquired upon exercise of a Stock Purchase Right granted to a
Participant resident outside of the state of California at the time the Stock Purchase 

  

 -11- 

 
Right is granted, whenever such grant date occurs, and (2) with respect to any Stock Purchase Right granted to a Participant resident in California
where the grant date occurs on or after the date, if any, upon which the Common Stock becomes a Listed Security or granted to an officer, Director or Consultant resident in California prior to such date, the Company shall have a right to repurchase
vested Shares acquired upon exercise of the Stock Purchase Right at any time within 90 days from termination of the Participant’s Continuous Service Status for Cause at the Participant’s original purchase price for the Shares; and
(B) with respect to Participants who are not officers, Directors or Consultants and who are resident in the state of California at the time a Stock Purchase Right is granted where the grant date occurs prior to the date, if any, upon which the
Common Stock becomes a Listed Security, the Company shall have the right to repurchase such Shares from the Participant upon the following terms: (1) the repurchase shall be made within 90 days of termination of the Participant’s
Continuous Service Status for Cause at the Fair Market Value of the Shares as of the date of termination, (2) consideration for the repurchase shall consist of cash or cancellation of purchase money indebtedness, and (3) the repurchase
right shall terminate upon the effective date of the Company’s initial public offering of its Common Stock. Nothing in this Section 11(b)(ii) shall in any way limit the Company’s right to purchase unvested Shares as set forth in the
applicable Restricted Stock Purchase Agreement. 
 (c) Other Provisions. The Restricted Stock Purchase Agreement shall contain
such other terms, provisions and conditions not inconsistent with the Plan as may be determined by the Administrator in its sole discretion. In addition, the provisions of Restricted Stock Purchase Agreements need not be the same with respect to
each purchaser. 
 (d) Rights as a Stockholder. Once the Stock Purchase Right is exercised, the purchaser shall have the rights
equivalent to those of a stockholder, and shall be a stockholder when his or her purchase is entered upon the records of the duly authorized transfer agent of the Company. No adjustment will be made for a dividend or other right for which the record
date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 14 of the Plan. 
 12.
Taxes. 
 (a) As a condition of the exercise of an Option or Stock Purchase Right granted under the Plan, the Participant (or in
the case of the Participant’s death, the person exercising the Option or Stock Purchase Right) shall make such arrangements as the Administrator may require for the satisfaction of any applicable federal, state, local or foreign withholding tax
obligations that may arise in connection with the exercise of the Option or Stock Purchase Right and the issuance of Shares. The Company shall not be required to issue any Shares under the Plan until such obligations are satisfied. If the
Administrator allows the withholding or surrender of Shares to satisfy a Participant’s tax withholding obligations under this Section 12 (whether pursuant to Section 12(c), (d) or (e), or otherwise), the Administrator shall not
allow Shares to be withheld in an amount that exceeds the minimum statutory withholding rates for federal and state tax purposes, including payroll taxes. 
 (b) In the case of an Employee and in the absence of any other arrangement, the Employee shall be deemed to have directed the Company to withhold or collect from his or her compensation an amount sufficient to satisfy
such tax obligations from the next payroll payment otherwise payable after the date of an exercise of the Option or Stock Purchase Right. 
  

 -12- 

 (c) This Section 12(c) shall apply only after the date, if any, upon which the Common Stock becomes
a Listed Security. In the case of Participant other than an Employee (or in the case of an Employee where the next payroll payment is not sufficient to satisfy such tax obligations, with respect to any remaining tax obligations), in the absence of
any other arrangement and to the extent permitted under the Applicable Laws, the Participant shall be deemed to have elected to have the Company withhold from the Shares to be issued upon exercise of the Option or Stock Purchase Right that number of
Shares having a Fair Market Value determined as of the applicable Tax Date (as defined below) equal to the amount required to be withheld. For purposes of this Section 12, the Fair Market Value of the Shares to be withheld shall be determined
on the date that the amount of tax to be withheld is to be determined under the Applicable Laws (the “Tax Date”). 
 (d) If
permitted by the Administrator, in its discretion, a Participant may satisfy his or her tax withholding obligations upon exercise of an Option or Stock Purchase Right by surrendering to the Company Shares that have a Fair Market Value determined as
of the applicable Tax Date equal to the amount required to be withheld. In the case of shares previously acquired from the Company that are surrendered under this Section 12(d), such Shares must have been owned by the Participant for more than
six (6) months on the date of surrender (or such other period of time as is required for the Company to avoid adverse accounting charges). 
 (e) Any election or deemed election by a Participant to have Shares withheld to satisfy tax withholding obligations under Section 12(c) or (d) above shall be irrevocable as to the particular Shares as to which the election is made
and shall be subject to the consent or disapproval of the Administrator. Any election by a Participant under Section 12(d) above must be made on or prior to the applicable Tax Date. 
 (f) In the event an election to have Shares withheld is made by a Participant and the Tax Date is deferred under Section 83 of the Code because no
election is filed under Section 83(b) of the Code, the Participant shall receive the full number of Shares with respect to which the Option or Stock Purchase Right is exercised but such Participant shall be unconditionally obligated to tender
back to the Company the proper number of Shares on the Tax Date. 
 13. Non-Transferability of Options and Stock Purchase
Rights. 
 (a) General. Except as set forth in this Section 13, Options and Stock Purchase Rights may not be sold,
pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will or by the laws of descent or distribution. The designation of a beneficiary by an Optionee will not constitute a transfer. An Option or Stock Purchase Right
may be exercised, during the lifetime of the holder of an Option or Stock Purchase Right, only by such holder or a transferee permitted by this Section 13. 
  

 -13- 

 (b) Limited Transferability Rights. Notwithstanding anything else in this Section 13,
prior to the date, if any, on which the Common Stock becomes a Listed Security, the Administrator may in its discretion grant Nonstatutory Stock Options that may be transferred by instrument to an inter vivos or testamentary trust in which the
Options are to be passed to beneficiaries upon the death of the trustor (settlor) or by gift to “Immediate Family” (as defined below), on such terms and conditions as the Administrator deems Emphasys Medical. Following the date, if any, on
which the Common Stock becomes a Listed Security, the Administrator may in its discretion grant transferable Nonstatutory Stock Options pursuant to Option Agreements specifying the manner in which such Nonstatutory Stock Options are transferable.
“Immediate Family” means any child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law, and shall include adoptive
relationships. 
 14. Adjustments Upon Changes in Capitalization, Merger or Certain Other Transactions. 
 (a) Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of Shares of Common Stock
covered by each outstanding Option or Stock Purchase Right, the number of Shares set forth in Section 3(a) above, and the number of Shares of Common Stock that have been authorized for issuance under the Plan but as to which no Options or Stock
Purchase Rights have yet been granted or that have been returned to the Plan upon cancellation or expiration of an Option or Stock Purchase Right, as well as the price per Share of Common Stock covered by each such outstanding Option or Stock
Purchase Right, shall be proportionately adjusted for any increase or decrease in the number of issued Shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination, recapitalization or reclassification of the
Common Stock, or any other increase or decrease in the number of issued Shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be
deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Administrator, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no
issuance by the Company of shares of stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares of Common Stock
subject to an Option or Stock Purchase Right. 
 (b) Dissolution or Liquidation. In the event of the dissolution or liquidation
of the Company, each Option and Stock Purchase Right will terminate immediately prior to the consummation of such action, unless otherwise determined by the Administrator. 
 (c) Corporate Transaction. In the event of a Corporate Transaction, each outstanding Option or Stock Purchase Right shall be assumed or an
equivalent option or right shall be substituted by such successor corporation or a parent or subsidiary of such successor corporation (the “Successor Corporation”), unless the Successor Corporation does not agree to assume the award
or to substitute an equivalent option or right, in which case such Option or Stock Purchase Right shall terminate upon the consummation of the transaction. 
  

 -14- 

 (d) Certain Distributions. In the event of any distribution to the Company’s
stockholders of securities of any other entity or other assets (other than dividends payable in cash or stock of the Company) without receipt of consideration by the Company, the Administrator may, in its discretion, Emphasys Medically adjust the
price per Share of Common Stock covered by each outstanding Option or Stock Purchase Right to reflect the effect of such distribution. 
 15.
Time of Granting Options and Stock Purchase Rights. The date of grant of an Option or Stock Purchase Right shall, for all purposes, be the date on which the Administrator makes the determination granting such Option or Stock Purchase
Right, or such other date as is determined by the Administrator, provided that in the case of any Incentive Stock Option, the grant date shall be the later of the date on which the Administrator makes the determination granting such Incentive Stock
Option or the date of commencement of the Optionee’s employment relationship with the Company. Notice of the determination shall be given to each Employee or Consultant to whom an Option or Stock Purchase Right is so granted within a reasonable
time after the date of such grant. 
 16. Amendment and Termination of the Plan. 
 (a) Authority to Amend or Terminate. The Board may at any time amend, alter, suspend or discontinue the Plan, but no amendment, alteration,
suspension or discontinuation (other than an adjustment pursuant to Section 14 above) shall be made that would materially and adversely affect the rights of any Optionee or holder of Stock Purchase Rights under any outstanding grant, without
his or her consent. In addition, to the extent necessary and desirable to comply with the Applicable Laws, the Company shall obtain stockholder approval of any Plan amendment in such a manner and to such a degree as required. 
 (b) Effect of Amendment or Termination. No amendment or termination of the Plan shall materially and adversely affect Options or Stock
Purchase Rights already granted, unless mutually agreed otherwise between the Optionee or holder of the Stock Purchase Rights and the Administrator, which agreement must be in writing and signed by the Optionee or holder and the Company. 

(c) Accounting Issues. Notwithstanding anything else to the contrary in this Section 16, the Administrator may at any time amend or
adjust the Plan or an outstanding award issued under the Plan without the consent of the affected Participant(s) if such amendment or adjustment is necessary to avoid the Company’s incurring adverse accounting charges. 
 17. Conditions Upon Issuance of Shares. Notwithstanding any other provision of the Plan or any agreement entered into by the Company
pursuant to the Plan, the Company shall not be obligated, and shall have no liability for failure, to issue or deliver any Shares under the Plan unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined
by the Company in consultation with its legal counsel. As a condition to the exercise of an Option or Stock Purchase Right, the Company may require the person exercising the award to represent and warrant at the time of any such exercise that the
Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by law. 
  

 -15- 

 18. Reservation of Shares. The Company, during the term of this Plan, will at all times
reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan. 
 19.
Agreements. Options and Stock Purchase Rights shall be evidenced by Option Agreements and Restricted Stock Purchase Agreements, respectively, in such form(s) as the Administrator shall from time to time approve. 
 20. Stockholder Approval. If required by the Applicable Laws, continuance of the Plan shall be subject to approval by the stockholders of
the Company within twelve (12) months before or after the date the Plan is adopted. Such stockholder approval shall be obtained in the manner and to the degree required under the Applicable Laws. 
 21. Information and Documents to Optionees and Purchasers. Prior to the date, if any, upon which the Common Stock becomes a Listed Security
and if required by the Applicable Laws, the Company shall provide financial statements at least annually to each Optionee and to each individual who acquired Shares pursuant to the Plan, during the period such Optionee or purchaser has one or more
Options or Stock Purchase Rights outstanding, and in the case of an individual who acquired Shares pursuant to the Plan, during the period such individual owns such Shares. The Company shall not be required to provide such information if the
issuance of Options or Stock Purchase Rights under the Plan is limited to key employees whose duties in connection with the Company assure their access to equivalent information.

 EMPHASYS MEDICAL, INC. 
 2000 STOCK PLAN 
 STOCK OPTION AGREEMENT 
 1. Grant of Option. Emphasys Medical, Inc, a Delaware corporation (the “Company”), hereby grants to «Optionee»
(“Optionee”), an option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”) set forth in the Notice of Stock Option Grant (the “Notice”), at the
exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions and provisions of the Emphasys Medical, Inc. 2000 Stock Plan (the “Plan”) adopted by the Company, which is
incorporated in this Agreement by reference. Unless otherwise defined in this Agreement, the terms used in this Agreement shall have the meanings defined in the Plan. 
 2. Designation of Option. This Option is intended to be an Incentive Stock Option as defined in Section 422 of the Code only to the extent so designated in the Notice, and to the extent it is not so
designated or to the extent the Option does not qualify as an Incentive Stock Option, it is intended to be a Nonstatutory Stock Option. 
 Notwithstanding the above, if designated as an Incentive Stock Option, in the event that the Shares subject to this Option (and all other Incentive Stock Options granted to Optionee by the Company or any Parent or Subsidiary, including
under other plans of the Company) that first become exercisable in any calendar year have an aggregate fair market value (determined for each Share as of the date of grant of the option covering such Share) in excess of $100,000, the Shares in
excess of $100,000 shall be treated as subject to a Nonstatutory Stock Option, in accordance with Section 5(c) of the Plan. 
 3.
Exercise of Option. This Option shall be exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the Notice and with the provisions of Section 10 of the Plan as follows: 
 (a) Right to Exercise. 
 (i)
This Option may not be exercised for a fraction of a share. 
 (ii) In the event of Optionee’s death, disability or other termination
of employment, the exercisability of the Option is governed by Section 5 below, subject to the limitations contained in this Section 3. 
 (iii) In no event may this Option be exercised after the Expiration Date of the Option as set forth in the Notice. 

 (b) Method of Exercise. 
 (i) This Option shall be exercisable by execution and delivery of the Early Exercise Notice and Restricted Stock Purchase Agreement attached hereto as
Exhibit A, the Exercise Notice and Restricted Stock Purchase Agreement attached hereto as Exhibit B, or any other form of written notice approved for such purpose by the Company which shall state Optionee’s election to
exercise the Option, the number of Shares in respect of which the Option is being exercised, and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company
pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be delivered to the Company by such means as are determined by the Plan Administrator in its discretion to constitute adequate delivery. The written
notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon receipt by the Company of such written notice accompanied by the Exercise Price. 
 (ii) As a condition to the exercise of this Option and as further set forth in Section 12 of the Plan, Optionee agrees to make adequate provision
for federal, state or other tax withholding obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise. 
 (iii) The Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise of the Option unless such
issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be exercised until such time as the Plan has been approved by the stockholders of
the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable federal or state securities or other law or regulation, including any rule
under Part 221 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the
Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on which the Option is exercised with respect to such Shares. 
 4. Method of Payment. Payment of the Exercise Price shall be by any of the following, or a combination of the following, at the election of
Optionee: 
 (a) cash or check; 
 (b) prior to the date, if any, upon which the Common Stock becomes a Listed Security, by surrender of other shares of Common Stock of the Company that have an aggregate Fair Market Value on the date of surrender equal to the Exercise Price
of the Shares as to which the Option is being exercised. In the case of shares acquired directly or indirectly from the Company, such shares must have been owned by Optionee for more than six (6) months on the date of surrender (or such other
period of time as is necessary to avoid the Company’s incurring adverse accounting charges); or 
  

 -2- 

 (c) following the date, if any, upon which the Common Stock is a Listed Security, delivery of a properly
executed exercise notice together with irrevocable instructions to a broker approved by the Company to deliver promptly to the Company the amount of sale or loan proceeds required to pay the exercise price. 
 5. Termination of Relationship. Following the date of termination of Optionee’s Continuous Service Status for any reason (the
“Termination Date”), Optionee may exercise the Option only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of the Termination Date, or if Optionee does not
exercise this Option within the Termination Period set forth in the Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as
set forth in the Notice. 
 (a) Termination. In the event of termination of Optionee’s Continuous Service Status other
than as a result of Optionee’s disability or death, Optionee may, to the extent otherwise so entitled at the date of such termination (the “Termination Date”), exercise this Option during the Termination Period set forth in the
Notice. 
 (b) Other Terminations. In connection with any termination other than a termination covered by Section 5(a),
Optionee may exercise the Option only as described below: 
 (i) Termination upon Disability of Optionee. In the event of
termination of Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within twelve months from the Termination Date, exercise this Option to the extent Optionee was entitled to exercise it as of
such Termination Date. 
 (ii) Death of Optionee. In the event of the death of Optionee (a) during the term of this
Option and while an Employee or Consultant of the Company and having been in Continuous Service Status since the date of grant of the Option, or (b) within thirty (30) days after Optionee’s Termination Date, the Option may be
exercised at any time within twelve months following the date of death by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent Optionee was entitled to exercise the
Option as of the Termination Date. 
 6. Non-Transferability of Option. Except as otherwise set forth in the Notice, this
Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of Optionee. 
 7. Tax Consequences. Below is a brief summary as of the date of
this Option of certain of the federal tax consequences of exercise of this Option and disposition of the Shares under the laws in effect as of the Date of Grant. THIS SUMMARY IS INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
  

 -3- 

 (a) Incentive Stock Option. 
 (i) Tax Treatment upon Exercise and Sale of Shares. If this Option qualifies as an Incentive Stock Option, there will be no regular federal
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 an adjustment to the alternative minimum tax for federal tax
purposes and may subject Optionee to the alternative minimum tax in the year of exercise. If Shares issued upon exercise of an Incentive Stock Option are held for at least one year after exercise and are disposed of at least two years after the
Option grant date, any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares issued upon exercise of an Incentive Stock Option are disposed of within such one-year period
or within two years after the Option grant date, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent of the difference between the Exercise Price and the lesser of
(i) the fair market value of the Shares on the date of exercise, or (ii) the sale price of the Shares. 
 (ii) Notice of
Disqualifying Dispositions. With respect to any Shares issued upon exercise of an Incentive Stock Option, if Optionee sells or otherwise disposes of such Shares on or before the later of (i) the date two years after the Option grant
date, or (ii) the date one year after the date of exercise, Optionee shall immediately notify the Company in writing of such disposition. Optionee acknowledges and agrees that he or she may be subject to income tax withholding by the Company on
the compensation income recognized by Optionee from the early disposition by payment in cash or out of the current earnings paid to Optionee. 
 (b) Nonstatutory Stock Option. If this Option does not qualify as an Incentive Stock Option, there may be a regular federal (and state) income tax liability upon the exercise of the Option. Optionee 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 Optionee is an Employee, the Company will be required to
withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a percentage of this compensation income at the time of exercise. If Shares issued upon exercise of a Nonstatutory
Stock Option are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain for federal income tax purposes. 
 8. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or the underwriters managing any underwritten offering of the
Company’s securities, Optionee hereby agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however and whenever acquired (other than those included in the
registration) 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) from the effective date of such registration as may be requested by the Company or such
managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 
  

 -4- 

 9. Effect of Agreement. Optionee acknowledges receipt of a copy of the Plan and represents
that he or she is familiar with the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be bound by its contractual terms as set forth herein and in
the Plan. Optionee hereby agrees to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to the Option. In the event of a conflict between the terms and provisions of
the Plan and the terms and provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. The Option, including the Plan, constitutes the entire agreement between Optionee and the Company on the subject matter hereof and
supersedes all proposals, written or oral, and all other communications between the parties relating to such subject matter.

 EXHIBIT A 
 EMPHASYS MEDICAL, INC. 
 2000 STOCK PLAN 
 EARLY EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 
 This Agreement (“Agreement”) is made as of                     , by and between Emphasys
Medical, Inc., a Delaware corporation (the “Company”), and «Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to
them in the 2000 Stock Plan. 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to
exercise his or her option to purchase                      shares of the Common Stock (the “Shares”) of the Company under
and pursuant to the Company’s 2000 Stock Plan (the “Plan”) and the Stock Option Agreement granted                     
(the “Option Agreement”). Of these Shares, Purchaser has elected to purchase                      of those Shares which have
become vested as of the date hereof under the Vesting Schedule set forth in the Notice of Stock Option Grant (the “Vested Shares”) and
                     Shares which have not yet vested under such Vesting Schedule (the “Unvested Shares”). The purchase price
for the Shares shall be $«ExercisePrice» per Share for a total purchase price of $                    . The term
“Shares” refers to the purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization,
exchange or the like, and all new, substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company
simultaneously with the execution and delivery of this Agreement in accordance with the provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be
purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the exercise price therefor by Purchaser by (a) check made payable to the Company, (b) cancellation of indebtedness of the Company to Purchaser,
(c) delivery of shares of the Common Stock of the Company in accordance with Section 4 of the Option Agreement, or (d) a combination of the foregoing. 
 3. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares while the
Shares are subject to the Company’s Repurchase Option (as defined below). After any Shares have been released from such Repurchase Option, Purchaser shall not assign, encumber or dispose of any interest in such Shares except in compliance with
the provisions below and applicable securities laws. 

 (a) Repurchase Option. 
 (i) In the event of the voluntary or involuntary termination of Purchaser’s employment or consulting relationship with the Company for any reason
(including death or disability), with or without cause, the Company shall upon the date of such termination (the “Termination Date”) have an irrevocable, exclusive option (the “Repurchase Option”) for a period of 90
days from such date to repurchase all or any portion of the Shares held by Purchaser as of the Termination Date which have not yet been released from the Company’s Repurchase Option at the original purchase price per Share specified in
Section 1 (adjusted for any stock splits, stock dividends and the like). 
 (ii) Unless the Company notifies Purchaser within 90 days
from the date of termination of Purchaser’s employment or consulting relationship that it does not intend to exercise its Repurchase Option with respect to some or all of the Shares, the Repurchase Option shall be deemed automatically exercised
by the Company as of the 90th day following such termination, provided that the Company may notify Purchaser that it is exercising its Repurchase Option as of a date prior to such 90th day. Unless Purchaser is otherwise notified by the Company
pursuant to the preceding sentence that the Company does not intend to exercise its Repurchase Option as to some or all of the Shares to which it applies at the time of termination, execution of this Agreement by Purchaser constitutes written notice
to Purchaser of the Company’s intention to exercise its Repurchase Option with respect to all Shares to which such Repurchase Option applies. The Company, at its choice, may satisfy its payment obligation to Purchaser with respect to exercise
of the Repurchase Option by either (A) delivering a check to Purchaser in the amount of the purchase price for the Shares being repurchased, or (B) in the event Purchaser is indebted to the Company, canceling an amount of such indebtedness
equal to the purchase price for the Shares being repurchased, or (C) by a combination of (A) and (B) so that the combined payment and cancellation of indebtedness equals such purchase price. In the event of any deemed automatic
exercise of the Repurchase Option pursuant to this Section 3(a)(ii) in which Purchaser is indebted to the Company, such indebtedness equal to the purchase price of the Shares being repurchased shall be deemed automatically canceled as of the
90th day following termination of Purchaser’s employment or consulting relationship unless the Company otherwise satisfies its payment obligations. As a result of any repurchase of Shares pursuant to this Section 3(a), the Company shall
become the legal and beneficial owner of the Shares being repurchased and shall have all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the number of Shares being repurchased by the
Company, without further action by Purchaser. 
 (iii) One hundred percent (100%) of the Shares shall initially be subject to the
Repurchase Option. The Unvested Shares shall be released from the Repurchase Option in accordance with the Vesting Schedule set forth in the Notice of Stock Option Grant until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share. 
 (b) Right of First Refusal. Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 3(b) (the “Right of First Refusal”). 
  

 -2- 

 (i) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a
written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed
Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered
Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 
 (ii)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 
 (iii) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(b) shall be the Offered Price. If the
Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (v) Holder’s Right to Transfer. If all of the 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 3(b), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the
provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to
change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred. 
 (vi) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section 3(b) notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of
Purchaser’s Immediate Family shall be exempt from the 

  

 -3- 

 
provisions of this Section 3(b). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother,
brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms
of this Section 3. 
 (c) Involuntary Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement, of any transfer
by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of the Shares on the date of transfer. Upon such a transfer, the person
acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by
the person acquiring the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be transferred pursuant
to Section 3(c)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The Company shall notify
Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined
by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company
and the Purchaser. 
 (d) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or
in part to any shareholder or shareholders of the Company or other persons or organizations. 
 (e) Restrictions Binding on
Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement, including, insofar as applicable, the Repurchase Option. In the event of any purchase
by the Company hereunder where the Shares or interest are held by a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Shares or interest to the Purchaser for consideration equal to the amount to be paid by
the Company hereunder. In the event the Repurchase Option is deemed exercised by the Company pursuant to Section 3(a)(ii) hereof, the Company may deem any transferee to have transferred the Shares or interest to Purchaser prior to their
purchase by the Company, and payment of the purchase price by the Company to such transferee shall be deemed to satisfy Purchaser’s obligation to pay such transferee for such Shares or interest, and also to satisfy the Company’s obligation
to pay Purchaser for such Shares or interest. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are satisfied. 
  

 -4- 

 (f) Termination of Rights. The right of first refusal granted the Company by
Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon 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 Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in
Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 6(a)(ii) herein and delivered to Purchaser. 
 4. Escrow of Unvested Shares. For purposes of facilitating the enforcement of the provisions of Section 3 above, Purchaser agrees,
immediately upon receipt of the certificate(s) for the Shares subject to the Repurchase Option, to deliver such certificate(s), together with an Assignment Separate from Certificate in the form attached to this Agreement as Attachment A
executed by Purchaser and by Purchaser’s spouse (if required for transfer), in blank, to the Secretary of the Company, or the Secretary’s designee, to hold such certificate(s) and Assignment Separate from Certificate in escrow and to take
all such actions and to effectuate all such transfers and/or releases as are in accordance with the terms of this Agreement. Purchaser hereby acknowledges that the Secretary of the Company, or the Secretary’s designee, is so appointed as the
escrow holder with the foregoing authorities as a material inducement to make this Agreement and that said appointment is coupled with an interest and is accordingly irrevocable. Purchaser agrees that said escrow holder shall not be liable to any
party hereof (or to any other party). The escrow holder may rely upon any letter, notice or other document executed by any signature purported to be genuine and may resign at any time. Purchaser agrees that if the Secretary of the Company, or the
Secretary’s designee, resigns as escrow holder for any or no reason, the Board of Directors of the Company shall have the power to appoint a successor to serve as escrow holder pursuant to the terms of this Agreement. 
 5. Investment and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the
following: 
 (a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information
about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in connection with, any
“distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 
 (b) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
  

 -5- 

 (c) Purchaser further acknowledges and understands that the securities must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. Purchaser understands
that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 

(d) Purchaser is familiar with the provisions of Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit
limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions.
Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require, among other things, that the Company be subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain circumstances, that
resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (e) below. 
 (e) Purchaser further understands that in the event all of the applicable requirements of Rule 144 or 701 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has
expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 
 (f) 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 any tax consultants
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 
 6. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. The certificate
or certificates representing the Shares shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
  

	 	(i)	 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN 

  

 -6- 

	 	 
ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT
AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE
WITH THE SECRETARY OF THE COMPANY. 

 (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall 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 shall have been so transferred. 
 7. No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 
 8. Section 83(b) Election. Purchaser understands that Section 83(a) of the Internal Revenue Code of 1986, as amended (the
“Code”), taxes as ordinary income for a Nonstatutory Stock Option and as alternative minimum taxable income for an Incentive Stock Option the difference between the amount paid for the Shares and the Fair Market Value of the Shares
as of the date any restrictions on the Shares lapse. In this context, “restriction” means the right of the Company to buy back the Shares pursuant to the Repurchase Option set forth in Section 3(a) of this Agreement. Purchaser
understands that Purchaser may elect to be taxed at the time the Shares are purchased, rather than when and as the Repurchase Option expires, by filing an election under Section 83(b) (an “83(b) Election”) of the Code with the
Internal Revenue Service within 30 days from the date of purchase. Even if the Fair Market Value of the Shares at the time of the execution of this Agreement equals the amount paid for the Shares, the election must be made to avoid income and
alternative minimum tax treatment under Section 83(a) in the future. Purchaser understands that failure to file such an election in a timely manner may result in adverse tax consequences for Purchaser. Purchaser further understands that an
additional copy of 

  

 -7- 

 
such election form should be filed with his or her federal income tax return for the calendar year in which the date of this Agreement falls. Purchaser
acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to purchase of the Shares hereunder, and does not purport to be complete. Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable provisions of the Code, the income tax laws of any municipality, state or foreign country in which Purchaser may reside, and the tax consequences of Purchaser’s death.

 Purchaser agrees that he or she will execute and deliver to the Company with this executed Agreement a copy of the Acknowledgment and
Statement of Decision Regarding Section 83(b) Election (the “Acknowledgment”) attached hereto as Attachment B. Purchaser further agrees that he or she will execute and submit with the Acknowledgment a copy of the
83(b) Election attached hereto as Attachment C (for tax purposes in connection with the early exercise of an option) if Purchaser has indicated in the Acknowledgment his or her decision to make such an election. 
 9. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or
the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however or
whenever acquired (other than those included in the registration) 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) from the effective date of such
registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 
 10. Miscellaneous. 
 (a)
Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California,
without giving effect to principles of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This Agreement sets
forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement,
shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 
 (c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 
  

 -8- 

 (d) Construction. This Agreement is the result of negotiations between and has been
reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the
parties hereto. 
 (e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed
sufficient when delivered personally or sent by telegram or fax or 48 hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such party’s address as set
forth below or as subsequently modified by written notice. 
 (f) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 
 (g) Successors
and Assigns. The rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the
prior written consent of the Company. 
 (h) California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS
AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS
THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS
SO EXEMPT.

 FOR VALUE RECEIVED and pursuant to that certain Early
Exercise Notice and Restricted Stock Purchase Agreement between the undersigned (“Purchaser”) and Emphasys Medical, Inc. (the “Company”) dated
                    ,          (the “Agreement”), Purchaser hereby sells,
assigns and transfers unto the Company
                                        
(                    ) shares of the Common Stock of the Company, standing in Purchaser’s name on the books of the Company and

 EXHIBIT B 
 EMPHASYS MEDICAL, INC. 
 2000 STOCK PLAN 
 EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 
 This Agreement (“Agreement”) is made as of                     , by and between Emphasys
Medical, Inc., a Delaware corporation (the “Company”), and «Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to
them in the 2000 Stock Plan. 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to
exercise his or her option to purchase                      shares of the Common Stock (the “Shares”) of the Company under
and pursuant to the Company’s 2000 Stock Plan (the “Plan”) and the Stock Option Agreement granted «Grant Date», (the “Option Agreement”). The purchase price for the Shares shall be
$«ExercisePrice» per Share for a total purchase price of $                    . The term “Shares” refers to the
purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of this Agreement in accordance with the
provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the
exercise price therefor by Purchaser by (a) check made payable to the Company, (b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of shares of the Common Stock of the Company in accordance with Section 4
of the Option Agreement, or (d) by a combination of the foregoing. 
 3. Limitations on Transfer. In addition to any other
limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the provisions below and applicable securities laws. 
 (a) Right of First Refusal. Before any Shares held by Purchaser or any transferee of Purchaser (either being sometimes referred to herein
as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth
in this Section 3(a) (the “Right of First Refusal”). 

 (i) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a
written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed
Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered
Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 
 (ii)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 
 (iii) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(a) shall be the Offered Price. If the
Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (v) Holder’s Right to Transfer. If all of the 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 3(a), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the
provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to
change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred. 
 (vi) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section 3(a) notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of
Purchaser’s Immediate Family shall be exempt from the provisions of this Section 3(a). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother, brother or sister. In such case,
the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms of this Section 3.

  

 -2- 

 (b) Involuntary Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement, of any transfer
by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(a)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the fair market value of the Shares on the date of transfer. Upon such a transfer, the person
acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by
the person acquiring the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be transferred pursuant
to Section 3(b)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The Company shall notify
Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined
by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company
and the Purchaser. 
 (c) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or
in part to any shareholder or shareholders of the Company or other persons or organizations. 
 (e) Restrictions Binding on
Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions
of this Agreement are satisfied. 
 (f) Termination of Rights. The right of first refusal granted the Company by
Section 3(a) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon 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 Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in
Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 5(a)(ii) herein and delivered to Purchaser. 
  

 -3- 

 4. Investment and Taxation Representations. In connection with the purchase of the Shares,
Purchaser represents to the Company the following: 
 (a) Purchaser is aware of the Company’s business affairs and financial condition
and has acquired sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for
resale in connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity.

 (b) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom,
which exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (c)
Purchaser further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and
understands that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are
registered or such registration is not required in the opinion of counsel for the Company. 
 (d) Purchaser is familiar with the provisions
of Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of
such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or
Rule 701, which rules require, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the
Shares for certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees
to the restrictions set forth in paragraph (e) below. 
 (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701
are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will
have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.

  

 -4- 

 (f) 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 any tax consultants 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. 
 5. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. The certificate or certificates representing the Shares shall bear the following legends (as well as any legends required by
applicable state and federal corporate and securities laws): 
  

	 	(i)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION
WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT
OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE
WITH THE SECRETARY OF THE COMPANY. 

 (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall 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 shall have been so transferred. 
 6. No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 
  

 -5- 

 7. Lock-Up Agreement. In connection with the initial public offering of the Company’s
securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any securities of the Company however or whenever acquired (other than those included in the registration) 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) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering.

 8. Miscellaneous. 
 (a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of
California, without giving effect to principles of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This
Agreement sets forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under
this Agreement, shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 
 (c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 
 (d) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be
deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 
 (e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient when delivered personally or sent by telegram or fax or forty-eight (48) hours after being deposited in
the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such party’s address as set forth below or as subsequently modified by written notice. 
 (f) Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original and all of which
together shall constitute one instrument. 
  

 -6- 

 (g) Successors and Assigns. The rights and benefits of this Agreement shall inure to the
benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the prior written consent of the Company. 
 (h) California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE
COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS THE SALE OF SECURITIES IS EXEMPT FROM
QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS SO EXEMPT.

Company is Involuntarily Terminated for any reason other than for Cause during the period beginning with the effective date of a Change of Control (as defined below) and ending on the first anniversary of such effective date, the vesting of the
Option shall automatically accelerate such that 100% of the shares then unvested at the effective time of termination. 

 (B) “Change of Control” shall mean any merger or consolidation of the Company (other
than a merger or consolidation in which the Company’s shareholders immediately before such merger own a majority of the voting stock of the surviving corporation immediately after the transaction), or any sale of all or substantially all of the
assets of the Company. 
 (C) “Involuntary Termination” shall include any termination of employment by the Company other
than (1) termination for Cause and (2) Optionee’s voluntary termination. Involuntary Termination also shall include Optionee’s voluntary termination following: (a) a substantial reduction in Optionee’s base salary
(other than in connection with a general decrease in base salaries for employees of the Company); (b) a material reduction in the kind or level of employee benefits with the result that the overall benefits package is significantly reduced;
(c) the relocation of Optionee’s place of employment to a facility or a location more than 50 miles from the Optionee’s then present location, without Optionee’s consent; (d) a material diminution of Optionee’s duties
or responsibilities; or (e) the failure of the Company to obtain the assumption of this Agreement by any successors. 
 (D)
“Cause” for Optionee’s termination of employment will exist at any time after the happening of one or more of the following events, in each case as determined in good faith by the Company’s Board of Directors:
(1) Optionee’s gross negligence or willful misconduct in performance of his duties hereunder where such gross negligence or unique misconduct has resulted or is likely to result in substantial and material damage to the Company or any of
its subsidiaries; (2) Optionee’s repeated or unjustified absence from the Company; (3) Optionee’s material and willful violation of any federal or state law; (4) The commission of any act of fraud by Optionee with respect to
the Company; (5) Optionee’s conviction of a felony or a crime involving moral turpitude causing material harm to the standing and reputation of the Company; or (6) Optionee’s incurable material breach of any element of the
Company’s Confidential Information and Invention Assignment Agreement, including without limitation, Optionee’s theft or other misappropriation of the Company’s proprietary information. 
 (iii) In no event may this Option be exercised after the Expiration Date of the Option as set forth in the Notice. 
 (b) Method of Exercise. 
 (i)
This Option shall be exercisable by execution and delivery of the Early Exercise Notice and Restricted Stock Purchase Agreement attached hereto as Exhibit A, the Exercise Notice and Restricted Stock Purchase Agreement attached hereto as
Exhibit B, or any other form of written notice approved for such purpose by the Company which shall state Optionee’s election to exercise the Option, the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder’s investment intent with respect to such Shares as may be required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be
delivered to the Company by such means as are determined by the Plan Administrator in its discretion to 

  

 -2- 

 
constitute adequate delivery. The written notice shall be accompanied by payment of the Exercise Price. This Option shall be deemed to be exercised upon
receipt by the Company of such written notice accompanied by the Exercise Price. 
 (ii) As a condition to the exercise of this Option and
as further set forth in Section 12 of the Plan, Optionee agrees to make adequate provision for federal, state or other tax withholding obligations, if any, which arise upon the vesting or exercise of the Option, or disposition of Shares,
whether by withholding, direct payment to the Company, or otherwise. 
 (iii) The Company is not obligated, and will have no liability for
failure, to issue or deliver any Shares upon exercise of the Option unless such issuance or delivery would comply with the Applicable Laws, with such compliance determined by the Company in consultation with its legal counsel. This Option may not be
exercised until such time as the Plan has been approved by the stockholders of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under Part 221 of Title 12 of the Code of Federal Regulations as promulgated by the Federal Reserve Board. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the Company as may be required by the Applicable Laws. Assuming such compliance, for income tax purposes the Shares shall be considered transferred to Optionee on the date on
which the Option is exercised with respect to such Shares. 
 4. Method of Payment. Payment of the Exercise Price shall be by
any of the following, or a combination of the following, at the election of Optionee: 
 (a) cash or check; 
 (b) prior to the date, if any, upon which the Common Stock becomes a Listed Security, by surrender of other shares of Common Stock of the Company that
have an aggregate Fair Market Value on the date of surrender equal to the Exercise Price of the Shares as to which the Option is being exercised. In the case of shares acquired directly or indirectly from the Company, such shares must have been
owned by Optionee for more than six (6) months on the date of surrender (or such other period of time as is necessary to avoid the Company’s incurring adverse accounting charges); or 
 (c) following the date, if any, upon which the Common Stock is a Listed Security, delivery of a properly executed exercise notice together with
irrevocable instructions to a broker approved by the Company to deliver promptly to the Company the amount of sale or loan proceeds required to pay the exercise price. 
 5. Termination of Relationship. Following the date of termination of Optionee’s Continuous Service Status for any reason (the “Termination Date”), Optionee may exercise the Option
only as set forth in the Notice and this Section 5. To the extent that Optionee is not entitled to exercise this Option as of the Termination Date, or if Optionee does not exercise this Option within the Termination Period set forth in the
Notice or the termination periods set forth below, the Option shall terminate in its entirety. In no event, may any Option be exercised after the Expiration Date of the Option as set forth in the Notice. 
  

 -3- 

 (a) Termination. In the event of termination of Optionee’s Continuous Service Status
other than as a result of Optionee’s disability or death, Optionee may, to the extent otherwise so entitled at the date of such termination (the “Termination Date”), exercise this Option during the Termination Period set forth
in the Notice. 
 (b) Other Terminations. In connection with any termination other than a termination covered by
Section 5(a), Optionee may exercise the Option only as described below: 
 (i) Termination upon Disability of Optionee. In
the event of termination of Optionee’s Continuous Service Status as a result of Optionee’s disability, Optionee may, but only within twelve months from the Termination Date, exercise this Option to the extent Optionee was entitled to
exercise it as of such Termination Date. 
 (ii) Death of Optionee. In the event of the death of Optionee (a) during the
term of this Option and while an Employee or Consultant of the Company and having been in Continuous Service Status since the date of grant of the Option, or (b) within thirty (30) days after Optionee’s Termination Date, the Option
may be exercised at any time within twelve months following the date of death by Optionee’s estate or by a person who acquired the right to exercise the Option by bequest or inheritance, but only to the extent Optionee was entitled to exercise
the Option as of the Termination Date. 
 6. Non-Transferability of Option. Except as otherwise set forth in the Notice, this
Option may not be transferred in any manner otherwise than by will or by the laws of descent or distribution and may be exercised during the lifetime of Optionee only by him or her. The terms of this Option shall be binding upon the executors,
administrators, heirs, successors and assigns of Optionee. 
 7. Tax Consequences. Below is a brief summary as of the date of
this Option of certain of the federal tax consequences of exercise of this Option and disposition of the Shares under the laws in effect as of the Date of Grant. THIS SUMMARY IS INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES. 
 (a) Incentive Stock Option.

 (i) Tax Treatment upon Exercise and Sale of Shares. If this Option qualifies as an Incentive Stock Option, there will be no
regular federal 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 an adjustment to the alternative minimum tax
for federal tax purposes and may subject Optionee to the alternative minimum tax in the year of exercise. If Shares issued upon exercise of an Incentive Stock Option are held for at least one year after exercise and are disposed of at least two
years after the Option grant date, 

  

 -4- 

 
any gain realized on disposition of the Shares will also be treated as long-term capital gain for federal income tax purposes. If Shares issued upon exercise
of an Incentive Stock Option are disposed of within such one-year period or within two years after the Option grant date, any gain realized on such disposition will be treated as compensation income (taxable at ordinary income rates) to the extent
of the difference between the Exercise Price and the lesser of (i) the fair market value of the Shares on the date of exercise, or (ii) the sale price of the Shares. 
 (ii) Notice of Disqualifying Dispositions. With respect to any Shares issued upon exercise of an Incentive Stock Option, if Optionee sells
or otherwise disposes of such Shares on or before the later of (i) the date two years after the Option grant date, or (ii) the date one year after the date of exercise, Optionee shall immediately notify the Company in writing of such
disposition. Optionee acknowledges and agrees that he or she may be subject to income tax withholding by the Company on the compensation income recognized by Optionee from the early disposition by payment in cash or out of the current earnings paid
to Optionee. 
 (b) Nonstatutory Stock Option. If this Option does not qualify as an Incentive Stock Option, there may be a
regular federal (and state) income tax liability upon the exercise of the Option. Optionee 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 Optionee is an Employee, the Company will be required to withhold from Optionee’s compensation or collect from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise. If Shares issued upon exercise of a Nonstatutory Stock Option are held for at least one year, any gain realized on disposition of the Shares will be treated as long-term capital gain
for federal income tax purposes. 
 8. Lock-Up Agreement. In connection with the initial public offering of the Company’s
securities and upon request of the Company or the underwriters managing any underwritten offering of the Company’s securities, Optionee hereby agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any securities of the Company however and whenever acquired (other than those included in the registration) 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) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering.

 9. Effect of Agreement. Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with
the terms and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option and agrees to be bound by its contractual terms as set forth herein and in the Plan. Optionee hereby agrees
to accept as binding, conclusive and final all decisions and interpretations of the Plan Administrator regarding any questions relating to the Option. In the event of a conflict between the terms and provisions of the Plan and the terms and
provisions of the Notice and this Agreement, the Plan terms and provisions shall prevail. The Option, including the Plan, constitutes the entire agreement between Optionee and the Company on the subject matter hereof and supersedes all proposals,
written or oral, and all other communications between the parties relating to such subject matter.

 EXHIBIT A 
 EMPHASYS MEDICAL, INC. 
 2000 STOCK PLAN 
 EARLY EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 
 This Agreement (“Agreement”) is made as of                     , by and between Emphasys
Medical, Inc., a Delaware corporation (the “Company”), and «Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to
them in the 2000 Stock Plan. 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to
exercise his or her option to purchase                      shares of the Common Stock (the “Shares”) of the Company under
and pursuant to the Company’s 2000 Stock Plan (the “Plan”) and the Stock Option Agreement granted «GrantDate» (the “Option Agreement”). Of these Shares, Purchaser has elected to purchase
                     of those Shares which have become vested as of the date hereof under the Vesting Schedule set forth in the Notice of
Stock Option Grant (the “Vested Shares”) and                      Shares which have not yet vested under such Vesting
Schedule (the “Unvested Shares”). The purchase price for the Shares shall be $«ExercisePrice» per Share for a total purchase price of $            . The
term “Shares” refers to the purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger,
reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company
simultaneously with the execution and delivery of this Agreement in accordance with the provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be
purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the exercise price therefor by Purchaser by (a) check made payable to the Company, (b) cancellation of indebtedness of the Company to Purchaser,
(c) delivery of shares of the Common Stock of the Company in accordance with Section 4 of the Option Agreement, or (d) a combination of the foregoing. 
 3. Limitations on Transfer. In addition to any other limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares while the
Shares are subject to the Company’s Repurchase Option (as defined below). After any Shares have been released from such Repurchase Option, Purchaser shall not assign, encumber or dispose of any interest in such Shares except in compliance with
the provisions below and applicable securities laws. 

 (a) Repurchase Option. 
 (i) In the event of the voluntary or involuntary termination of Purchaser’s employment or consulting relationship with the Company for any reason
(including death or disability), with or without cause, the Company shall upon the date of such termination (the “Termination Date”) have an irrevocable, exclusive option (the “Repurchase Option”) for a period of 90
days from such date to repurchase all or any portion of the Shares held by Purchaser as of the Termination Date which have not yet been released from the Company’s Repurchase Option at the original purchase price per Share specified in
Section 1 (adjusted for any stock splits, stock dividends and the like). 
 (ii) Unless the Company notifies Purchaser within 90 days
from the date of termination of Purchaser’s employment or consulting relationship that it does not intend to exercise its Repurchase Option with respect to some or all of the Shares, the Repurchase Option shall be deemed automatically exercised
by the Company as of the 90th day following such termination, provided that the Company may notify Purchaser that it is exercising its Repurchase Option as of a date prior to such 90th day. Unless Purchaser is otherwise notified by the Company
pursuant to the preceding sentence that the Company does not intend to exercise its Repurchase Option as to some or all of the Shares to which it applies at the time of termination, execution of this Agreement by Purchaser constitutes written notice
to Purchaser of the Company’s intention to exercise its Repurchase Option with respect to all Shares to which such Repurchase Option applies. The Company, at its choice, may satisfy its payment obligation to Purchaser with respect to exercise
of the Repurchase Option by either (A) delivering a check to Purchaser in the amount of the purchase price for the Shares being repurchased, or (B) in the event Purchaser is indebted to the Company, canceling an amount of such indebtedness
equal to the purchase price for the Shares being repurchased, or (C) by a combination of (A) and (B) so that the combined payment and cancellation of indebtedness equals such purchase price. In the event of any deemed automatic
exercise of the Repurchase Option pursuant to this Section 3(a)(ii) in which Purchaser is indebted to the Company, such indebtedness equal to the purchase price of the Shares being repurchased shall be deemed automatically canceled as of the
90th day following termination of Purchaser’s employment or consulting relationship unless the Company otherwise satisfies its payment obligations. As a result of any repurchase of Shares pursuant to this Section 3(a), the Company shall
become the legal and beneficial owner of the Shares being repurchased and shall have all rights and interest therein or related thereto, and the Company shall have the right to transfer to its own name the number of Shares being repurchased by the
Company, without further action by Purchaser. 
 (iii) One hundred percent (100%) of the Shares shall initially be subject to the
Repurchase Option. The Unvested Shares shall be released from the Repurchase Option in accordance with the Vesting Schedule set forth in the Notice of Stock Option Grant until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share. 
 (b) Right of First Refusal. Before any Shares held by Purchaser or any
transferee of Purchaser (either being sometimes referred to herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this Section 3(b) (the “Right of First Refusal”). 
  

 -2- 

 (i) Notice of Proposed Transfer. The Holder of the Shares shall deliver to the Company a
written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other transferee (“Proposed
Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the same price (the “Offered
Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 
 (ii)
Exercise of Right of First Refusal. At any time within thirty (30) days after receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of
the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the purchase price determined in accordance with subsection (iii) below. 
 (iii) Purchase Price. The purchase price (“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(b) shall be the Offered Price. If the
Offered Price includes consideration other than cash, the cash equivalent value of the non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv) Payment. Payment of the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or in the manner and at the times set forth in the Notice. 
 (v) Holder’s Right to Transfer. If all of the 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 3(b), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at the Offered Price or at a higher price, provided that such sale or other
transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable securities laws and the Proposed Transferee agrees in writing that the
provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to
change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the
Holder may be sold or otherwise transferred. 
 (vi) Exception for Certain Family Transfers. Anything to the contrary
contained in this Section 3(b) notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to Purchaser’s Immediate Family or a trust for the benefit of
Purchaser’s Immediate Family shall be exempt from the 

  

 -3- 

 
provisions of this Section 3(b). “Immediate Family” as used herein shall mean spouse, lineal descendant or antecedent, father, mother,
brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares except in accordance with the terms
of this Section 3. 
 (c) Involuntary Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement, of any transfer
by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(b)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of the Shares on the date of transfer. Upon such a transfer, the person
acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by
the person acquiring the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be transferred pursuant
to Section 3(c)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The Company shall notify
Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined
by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company
and the Purchaser. 
 (d) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or
in part to any shareholder or shareholders of the Company or other persons or organizations. 
 (e) Restrictions Binding on
Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement, including, insofar as applicable, the Repurchase Option. In the event of any purchase
by the Company hereunder where the Shares or interest are held by a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Shares or interest to the Purchaser for consideration equal to the amount to be paid by
the Company hereunder. In the event the Repurchase Option is deemed exercised by the Company pursuant to Section 3(a)(ii) hereof, the Company may deem any transferee to have transferred the Shares or interest to Purchaser prior to their
purchase by the Company, and payment of the purchase price by the Company to such transferee shall be deemed to satisfy Purchaser’s obligation to pay such transferee for such Shares or interest, and also to satisfy the Company’s obligation
to pay Purchaser for such Shares or interest. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are satisfied. 
  

 -4- 

 (f) Termination of Rights. The right of first refusal granted the Company by
Section 3(b) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon 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 Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in
Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 6(a)(ii) herein and delivered to Purchaser. 
 4. Escrow of Unvested Shares. For purposes of facilitating the enforcement of the provisions of Section 3 above, Purchaser agrees,
immediately upon receipt of the certificate(s) for the Shares subject to the Repurchase Option, to deliver such certificate(s), together with an Assignment Separate from Certificate in the form attached to this Agreement as Attachment A
executed by Purchaser and by Purchaser’s spouse (if required for transfer), in blank, to the Secretary of the Company, or the Secretary’s designee, to hold such certificate(s) and Assignment Separate from Certificate in escrow and to take
all such actions and to effectuate all such transfers and/or releases as are in accordance with the terms of this Agreement. Purchaser hereby acknowledges that the Secretary of the Company, or the Secretary’s designee, is so appointed as the
escrow holder with the foregoing authorities as a material inducement to make this Agreement and that said appointment is coupled with an interest and is accordingly irrevocable. Purchaser agrees that said escrow holder shall not be liable to any
party hereof (or to any other party). The escrow holder may rely upon any letter, notice or other document executed by any signature purported to be genuine and may resign at any time. Purchaser agrees that if the Secretary of the Company, or the
Secretary’s designee, resigns as escrow holder for any or no reason, the Board of Directors of the Company shall have the power to appoint a successor to serve as escrow holder pursuant to the terms of this Agreement. 
 5. Investment and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the
following: 
 (a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired sufficient information
about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in connection with, any
“distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 
 (b) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
  

 -5- 

 (c) Purchaser further acknowledges and understands that the securities must be held indefinitely unless
they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the Company is under no obligation to register the securities. Purchaser understands
that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or such registration is not required in the opinion of counsel for the Company. 

(d) Purchaser is familiar with the provisions of Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit
limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of such issuer), in a non-public offering subject to the satisfaction of certain conditions.
Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or Rule 701, which rules require, among other things, that the Company be subject to the
reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified time periods, and under certain circumstances, that
resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees to the restrictions set forth in paragraph (e) below. 
 (e) Purchaser further understands that in the event all of the applicable requirements of Rule 144 or 701 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701 are not exclusive, the Staff of the Securities and Exchange Commission has
expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will have a substantial burden of proof in establishing that an exemption from
registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk. 
 (f) 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 any tax consultants
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 
 6. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. The certificate
or certificates representing the Shares shall bear the following legends (as well as any legends required by applicable state and federal corporate and securities laws): 
  

	 	(i)	 THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN 

  

 -6- 

	 	 
ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT
AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE
WITH THE SECRETARY OF THE COMPANY. 

 (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall 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 shall have been so transferred. 
 7. No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 
 8. Section 83(b) Election. Purchaser understands that Section 83(a) of the Internal Revenue Code of 1986, as amended (the
“Code”), taxes as ordinary income for a Nonstatutory Stock Option and as alternative minimum taxable income for an Incentive Stock Option the difference between the amount paid for the Shares and the Fair Market Value of the Shares
as of the date any restrictions on the Shares lapse. In this context, “restriction” means the right of the Company to buy back the Shares pursuant to the Repurchase Option set forth in Section 3(a) of this Agreement. Purchaser
understands that Purchaser may elect to be taxed at the time the Shares are purchased, rather than when and as the Repurchase Option expires, by filing an election under Section 83(b) (an “83(b) Election”) of the Code with the
Internal Revenue Service within 30 days from the date of purchase. Even if the Fair Market Value of the Shares at the time of the execution of this Agreement equals the amount paid for the Shares, the election must be made to avoid income and
alternative minimum tax treatment under Section 83(a) in the future. Purchaser understands that failure to file such an election in a timely manner may result in adverse tax consequences for Purchaser. Purchaser further understands that an
additional copy of 

  

 -7- 

 
such election form should be filed with his or her federal income tax return for the calendar year in which the date of this Agreement falls. Purchaser
acknowledges that the foregoing is only a summary of the effect of United States federal income taxation with respect to purchase of the Shares hereunder, and does not purport to be complete. Purchaser further acknowledges that the Company has
directed Purchaser to seek independent advice regarding the applicable provisions of the Code, the income tax laws of any municipality, state or foreign country in which Purchaser may reside, and the tax consequences of Purchaser’s death.

 Purchaser agrees that he or she will execute and deliver to the Company with this executed Agreement a copy of the Acknowledgment and
Statement of Decision Regarding Section 83(b) Election (the “Acknowledgment”) attached hereto as Attachment B. Purchaser further agrees that he or she will execute and submit with the Acknowledgment a copy of the
83(b) Election attached hereto as Attachment C (for tax purposes in connection with the early exercise of an option) if Purchaser has indicated in the Acknowledgment his or her decision to make such an election. 
 9. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or
the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however or
whenever acquired (other than those included in the registration) 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) from the effective date of such
registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the public offering. 
 10. Miscellaneous. 
 (a)
Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall be governed, construed and interpreted in accordance with the laws of the State of California,
without giving effect to principles of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This Agreement sets
forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement,
shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement shall not be construed as a waiver of any rights of such party. 
 (c) Severability. If one or more provisions of this Agreement are held to be unenforceable under applicable law, the parties agree to
renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of
the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms. 
  

 -8- 

 (d) Construction. This Agreement is the result of negotiations between and has been
reviewed by each of the parties hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the
parties hereto. 
 (e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed
sufficient when delivered personally or sent by telegram or fax or 48 hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such party’s address as set
forth below or as subsequently modified by written notice. 
 (f) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 
 (g) Successors
and Assigns. The rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the
prior written consent of the Company. 
 (h) California Corporate Securities Law. THE SALE OF THE SECURITIES WHICH ARE THE SUBJECT OF THIS
AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF THE SECURITIES OR THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO THE QUALIFICATION IS UNLAWFUL, UNLESS
THE SALE OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED UPON THE QUALIFICATION BEING OBTAINED, UNLESS THE SALE IS
SO EXEMPT.

 EXHIBIT B 
 EMPHASYS MEDICAL, INC. 
 2000 STOCK PLAN 
 EXERCISE NOTICE AND RESTRICTED STOCK PURCHASE AGREEMENT 
 This Agreement (“Agreement”) is made as of                     , by and between Emphasys
Medical, Inc., a Delaware corporation (the “Company”), and «Optionee» (“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have the meaning ascribed to
them in the 2000 Stock Plan. 
 1. Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to
exercise his or her option to purchase                      shares of the Common Stock (the “Shares”) of the Company under
and pursuant to the Company’s 2000 Stock Plan (the “Plan”) and the Stock Option Agreement granted «GrantDate», (the “Option Agreement”). The purchase price for the Shares shall be
$«ExercisePrice» per Share for a total purchase price of $                    . The term “Shares” refers to the
purchased Shares and all securities received in replacement of the Shares or as stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. 
 2. Time and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with the execution and delivery of this Agreement in accordance with the
provisions of Section 3(b) of the Option Agreement. On such date, the Company will deliver to Purchaser a certificate representing the Shares to be purchased by Purchaser (which shall be issued in Purchaser’s name) against payment of the
exercise price therefor by Purchaser by (a) check made payable to the Company, (b) cancellation of indebtedness of the Company to Purchaser, (c) delivery of shares of the Common Stock of the Company in accordance with Section 4
of the Option Agreement, or (d) by a combination of the foregoing. 
 3. Limitations on Transfer. In addition to any other
limitation on transfer created by applicable securities laws, Purchaser shall not assign, encumber or dispose of any interest in the Shares except in compliance with the provisions below and applicable securities laws. 
 (a) Right of First Refusal. Before any Shares held by Purchaser or any transferee of Purchaser (either being sometimes referred to herein
as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth
in this Section 3(a) (the “Right of First Refusal”). 
 (i) Notice of Proposed Transfer. The Holder of
the Shares shall deliver to the Company a written notice (the “Notice”) stating: (i) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (ii) the name of each proposed purchaser or other
transferee (“Proposed Transferee”); (iii) the number of Shares to be transferred to each Proposed Transferee; and (iv) the terms and conditions of each proposed sale or transfer. The Holder shall offer the Shares at the
same price (the “Offered Price”) and upon the same terms (or terms as similar as reasonably possible) to the Company or its assignee(s). 

 (ii) Exercise of Right of First Refusal. At any time within thirty (30) days after
receipt of the Notice, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all, but not less than all, of the Shares proposed to be transferred to any one or more of the Proposed Transferees, at the
purchase price determined in accordance with subsection (iii) below. 
 (iii) Purchase Price. The purchase price
(“Purchase Price”) for the Shares purchased by the Company or its assignee(s) under this Section 3(a) shall be the Offered Price. If the Offered Price includes consideration other than cash, the cash equivalent value of the
non-cash consideration shall be determined by the Board of Directors of the Company in good faith. 
 (iv) Payment. Payment of
the Purchase Price shall be made, at the option of the Company or its assignee(s), in cash (by check), by cancellation of all or a portion of any outstanding indebtedness, or by any combination thereof within 30 days after receipt of the Notice or
in the manner and at the times set forth in the Notice. 
 (v) Holder’s Right to Transfer. If all of the 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 3(a), then the Holder may sell or otherwise transfer such Shares to that Proposed Transferee at
the Offered Price or at a higher price, provided that such sale or other transfer is consummated within 60 days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance with any applicable
securities laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 shall continue to apply to the Shares in the hands of such Proposed Transferee. If the Shares described in the Notice are not transferred to the
Proposed Transferee within such period, or if the Holder proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the Company and/or its assignees shall again
be offered the Right of First Refusal before any Shares held by the Holder may be sold or otherwise transferred. 
 (vi) Exception for
Certain Family Transfers. Anything to the contrary contained in this Section 3(a) notwithstanding, the transfer of any or all of the Shares during Purchaser’s lifetime or on Purchaser’s death by will or intestacy to
Purchaser’s Immediate Family or a trust for the benefit of Purchaser’s Immediate Family shall be exempt from the provisions of this Section 3(a). “Immediate Family” as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee or other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section, and there shall be no further transfer of such Shares
except in accordance with the terms of this Section 3. 
  

 -2- 

 (b) Involuntary Transfer. 
 (i) Company’s Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement, of any transfer
by operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(a)(vi) above) of all or a portion of the Shares by the record holder thereof, the Company
shall have an option to purchase all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement or the fair market value of the Shares on the date of transfer. Upon such a transfer, the person
acquiring the Shares shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the Company for a period of thirty (30) days following receipt by the Company of written notice by
the person acquiring the Shares. 
 (ii) Price for Involuntary Transfer. With respect to any stock to be transferred pursuant
to Section 3(b)(i), the price per Share shall be a price set by the Board of Directors of the Company that will reflect the current value of the stock in terms of present earnings and future prospects of the Company. The Company shall notify
Purchaser or his or her executor of the price so determined within thirty (30) days after receipt by it of written notice of the transfer or proposed transfer of Shares. However, if the Purchaser does not agree with the valuation as determined
by the Board of Directors of the Company, the Purchaser shall be entitled to have the valuation determined by an independent appraiser to be mutually agreed upon by the Company and the Purchaser and whose fees shall be borne equally by the Company
and the Purchaser. 
 (c) Assignment. The right of the Company to purchase any part of the Shares may be assigned in whole or
in part to any shareholder or shareholders of the Company or other persons or organizations. 
 (e) Restrictions Binding on
Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject to the provisions of this Agreement. Any sale or transfer of the Company’s Shares shall be void unless the provisions
of this Agreement are satisfied. 
 (f) Termination of Rights. The right of first refusal granted the Company by
Section 3(a) above and the option to repurchase the Shares in the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon 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 Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of the right of first refusal described in
Section 3(b) above, a new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred to in Section 5(a)(ii) herein and delivered to Purchaser. 
 4. Investment and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the
following: 
  

 -3- 

 (a) Purchaser is aware of the Company’s business affairs and financial condition and has acquired
sufficient information about the Company to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing these securities for investment for his or her own account only and not with a view to, or for resale in
connection with, any “distribution” thereof within the meaning of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer the Shares to any person or entity. 

(b) Purchaser understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein. 
 (c) Purchaser
further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands
that the Company is under no obligation to register the securities. Purchaser understands that the certificate(s) evidencing the securities will be imprinted with a legend which prohibits the transfer of the securities unless they are registered or
such registration is not required in the opinion of counsel for the Company. 
 (d) Purchaser is familiar with the provisions of
Rules 144 and 701, each promulgated under the Securities Act, which, in substance, permit limited public resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate of
such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144 or
Rule 701, which rules require, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, that resales of securities take place only after the holder of the Shares has held the
Shares for certain specified time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to brokered transactions. Notwithstanding this paragraph (d), Purchaser acknowledges and agrees
to the restrictions set forth in paragraph (e) below. 
 (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 144 or 701 are not satisfied, registration under the Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding the fact that Rules 144 and 701
are not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 or 701 will
have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who participate in such transactions do so at their own risk.

 (f) 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 any tax consultants 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. 

 

 -4- 

 5. Restrictive Legends and Stop-Transfer Orders. 
 (a) Legends. The certificate or certificates representing the Shares shall bear the following legends (as well as any legends required by
applicable state and federal corporate and securities laws): 
  

	 	(i)	THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION
WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL FOR THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT
OF 1933. 

  

	 	(ii)	THE SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE STOCKHOLDER, A COPY OF WHICH IS ON FILE
WITH THE SECRETARY OF THE COMPANY. 

 (b) Stop-Transfer Notices. Purchaser agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own securities, it may make appropriate notations to
the same effect in its own records. 
 (c) Refusal to Transfer. The Company shall 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 shall have been so transferred. 
 6. No Employment Rights. Nothing in this Agreement shall affect in any
manner whatsoever the right or power of the Company, or a parent or subsidiary of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason, with or without cause. 
 7. Lock-Up Agreement. In connection with the initial public offering of the Company’s securities and upon request of the Company or
the underwriters managing any underwritten offering of the Company’s securities, Purchaser agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the 

  

 -5- 

 
Company however or whenever acquired (other than those included in the registration) 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) from the effective date of such registration as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be
requested by the underwriters at the time of the public offering. 
 8. Miscellaneous. 
 (a) Governing Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall
be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of law. 
 (b) Entire Agreement; Enforcement of Rights. This Agreement sets forth the entire agreement and understanding of the parties relating to the subject matter herein and merges all prior discussions between
them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this
Agreement shall not be construed as a waiver of any rights of such party. 
 (c) Severability. If one or more provisions of
this Agreement are held to be unenforceable under applicable law, the parties agree to renegotiate such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such provision, then
(i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its
terms. 
 (d) Construction. This Agreement is the result of negotiations between and has been reviewed by each of the parties
hereto and their respective counsel, if any; accordingly, this Agreement shall be deemed to be the product of all of the parties hereto, and no ambiguity shall be construed in favor of or against any one of the parties hereto. 
 (e) Notices. Any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient when delivered
personally or sent by telegram or fax or forty-eight (48) hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed to the party to be notified at such party’s address as set forth
below or as subsequently modified by written notice. 
 (f) Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original and all of which together shall constitute one instrument. 
 (g) Successors
and Assigns. The rights and benefits of this Agreement shall inure to the benefit of, and be enforceable by the Company’s successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the
prior written consent of the Company.
