 WHEREAS, the Prior Investors have certain registration and other rights under the

 WHEREAS, the Company, to induce the Series D Investors to purchase shares of the Company’s Series D
Preferred Stock (the “Shares”) pursuant to the Series D Agreement, desires to grant certain registration rights and other rights to the Series D Investors, and the Prior Investors desire to facilitate such grant; 

WHEREAS, the sale of the Shares to the Series D Investors is conditioned upon the registration rights and other rights being extended to the
Series D Investors; and 
 WHEREAS, the Prior Rights Agreement may be amended, waived or modified as set forth in Section 4.7 thereof.

 NOW, THEREFORE, in consideration of the mutual promises and covenants hereinafter set forth, the parties agree as follows: 

 Section 1. Termination of Prior Rights. The Company and the Prior Investors, to
induce the Series D Investors to invest in the Company, accept and agree to the termination of all prior rights under the Prior Rights Agreement, and accept and agree to be bound by the terms of this Agreement. 

Section 2. Registration Rights. 

2.1 Definitions. As used in this Agreement:

“Act”). 
 (b) The term “Form S-3” means such form under the Act as in effect on the date hereof or

for purposes of meeting any threshold tests under this Agreement, including this Section 2.1(e) and 2.1(f) below. 
 (f) The term
“Major Series D Investor” means each Holder holding not less than 2,000 shares of Series D Preferred Stock or 825,000 shares of Common Stock (adjusted as each such number may be adjusted from time to time for stock splits, stock
dividends, combinations, subdivisions, recapitalizations and the like) issued upon conversion of the Series D Preferred Stock. 
 (g) The
term “person” means an individual, a partnership, a corporation, a limited liability company, an association, a joint stock company, a trust, a joint venture, an unincorporated organization and a Governmental Authority or any

Series C Preferred Stock and Series D Preferred Stock of the Company (the “Preferred Stock”), and 
 (ii) any other
shares of Common Stock of the Company issued as (or issuable upon the conversion or exercise of any warrant, right or other security which is issued as) a dividend or other distribution with respect to, or in exchange for or in replacement of, the
Preferred Stock excluding in all cases, however, any Registrable Securities sold by a person in a transaction in which his or her rights under this Agreement are not assigned; provided, however, that Common Stock or other securities
shall only be treated as Registrable Securities if and so long as they have not been (A) sold to or through a broker or dealer or underwriter in a public distribution or a public securities transaction, or (B) sold in a transaction exempt
from the registration and prospectus delivery requirements of the Act under Section 4(1) thereof so that all transfer restrictions, and restrictive legends with respect thereto, if any, are removed upon the consummation of such sale. 

(j) The number of shares of “Registrable Securities then outstanding” shall be determined by the number of shares of Common
Stock outstanding which are, and the number of shares of Common Stock issuable pursuant to then exercisable or convertible securities which are, Registrable Securities. 

(k) The term “Series D Initiating Holders” means any Holder or Holders who in the aggregate hold no less than fifty percent
(50%) of the shares of Common Stock issuable or issued upon conversion of the Series D Preferred Stock. 
 (l) The term
“WKSI” means a well-known seasoned issuer, as defined under SEC Rule 405. 
 2.2 Requested Registration. 

(a) If the Company shall receive at any time after six (6) months after the effective date of the first registration statement for a
public offering of securities of the Company (other than a registration statement relating either to the sale of securities to employees of the Company pursuant to a stock option, stock purchase or similar plan or a SEC Rule 145 transaction) (the
“Initial Public Offering”), a written request from the Initiating Holders or Series D Initiating Holders that the Company file a registration statement under the Act covering the registration of not less than fifty percent
(50%) of the Registrable Securities then outstanding and held by the holders of (i) Preferred Stock or (ii) Series D Preferred Stock, as applicable, (or any lesser number of shares if the anticipated aggregate offering price, net of
underwriting discounts and commissions would exceed $5,000,000) (such request by the Initiating Holders, a “Preferred Demand” and such request by the Series D Initiating Holders, a “Series D Demand” and such
requested securities in either case, the “Demand Securities”)) then the Company shall, within ten (10) days of the receipt thereof, give written notice of such request to all Holders and shall, subject to the limitations of
subsection 

 
2.2(b), use its best efforts to effect as soon as practicable, and in any event within sixty (60) days of the receipt of such request, the registration under the Act of all Registrable
Securities which the Holders request to be registered in a written request given within twenty (20) days of the mailing of such notice by the Company in accordance with Section 5.5. 

(b) If the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D Demand, intend to
distribute the Registrable Securities covered by their request by means of an underwriting, they shall so advise the Company as a part of their request made pursuant to this Section 2.2 and the Company shall include such information in the
written notice referred to in subsection 2.2(a). In such event, the right of any Holder to include such Holder’s Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the
inclusion of such Holder’s Registrable Securities in the underwriting (unless otherwise mutually agreed by a majority in interest of the Initiating Holders, pursuant to a Preferred Demand, or a majority in interest of the Series D Initiating
Holders, pursuant to a Series D Demand, and such Holder) to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the Company as provided in subsection 2.4(e)) enter into an
underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting by a majority in interest of the Initiating Holders, pursuant to a Preferred Demand, or a majority in interest of the Series D Initiating
Holders, pursuant to a Series D Demand. Notwithstanding any other provision of this Section 2.2, if the underwriter advises the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D
Demand, in writing that marketing factors require a limitation of the number of shares to be underwritten, then the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D Demand, shall so
advise all Holders of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares of Registrable Securities that may be included in the underwriting shall be allocated among all Holders thereof, including
the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D Demand, in proportion (as nearly as practicable) to the amount of Registrable Securities of the Company owned by each Holder (a
“Cutback Registration”). The Company shall not include in any registration pursuant to a Preferred Demand or Series D Demand that is an underwritten offering any securities that are held by an employee of the Company or any of its
subsidiaries or any person controlled by any such employee without the prior written consent of the managing underwriters and shall not include in any registration pursuant to a Preferred Demand or Series D Demand any securities that are not
Registrable Securities without the prior written consent of the holders of a majority of the Registrable Securities held by the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D Demand,
included in such registration. 
 (c) The Company is obligated to effect only one (1) such registration pursuant to a Preferred Demand
and two (2) such registrations pursuant to a Series D Demand; provided that a Cutback Registration shall not be deemed a registration pursuant to a Preferred Demand or Series D Demand if less than 75% of the securities requesting registration
in such demand are not registered pursuant to such registration. 

 (d) Notwithstanding the foregoing, if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 2.2, a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the Company, it would be materially and adversely detrimental to the
Company and its shareholders for such registration statement to be filed and it is therefore essential to defer the filing of such registration statement, the Company shall have the right to defer such filing for a period of not more than ninety
(90) days after receipt of the request of the Initiating Holders, pursuant to a Preferred Demand, or the Series D Initiating Holders, pursuant to a Series D Demand; provided, however, that the Company may not utilize this right more than once
in any twelve (12) month period. 
 (e) Notwithstanding the foregoing, the Company shall not be obligated to effect, or to take any
action to effect, any such registration pursuant to this Section 2.2 during the period starting with the date of filing of, and ending on a date ninety (90) days after the effective date of, a Company-initiated registration; provided the
Company is actively employing in good faith all reasonable efforts to cause such registration statement to become effective. 
 2.3
Company Registration. If (but without any obligation to do so) the Company proposes to register (including for this purpose a registration effected by the Company for shareholders other than the Holders) any of its Common Stock or other
securities under the Act in connection with a public offering of such securities (other than a registration relating either to the sale of securities to participants in a Company stock option, stock purchase or similar plan on Form S-8), the Company
shall, at least thirty (30) days prior to filing such registration statement, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within twenty (20) days after mailing of such notice
by the Company in accordance with Section 4.5, the Company shall, subject to the provisions of Section 2.8, use its best efforts to cause to be registered under the Act all of the Registrable Securities that each such Holder has requested
to be registered. 
 2.4 Obligations of the Company. Whenever required under this Section 2 to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably possible: 
 (a) Prepare and file with the SEC a registration
statement with respect to such Registrable Securities and use its best efforts to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep
such registration statement effective for up to one hundred twenty (120) days. 
 (b) Prepare and file with the SEC such amendments
and supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Act with respect to the disposition of all securities covered by such
registration statement. 
 (c) Furnish to the Holders such numbers of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the Act, and such other 

 
documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

(d) Use its best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue
Sky laws of such jurisdictions as shall be reasonably requested by the Holders, provided that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service of
process in any such states or jurisdictions. 
 (e) In the event of any underwritten public offering, enter into and perform its
obligations under an underwriting agreement, in usual and customary form, with the managing underwriter of such offering. Each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement. 

(f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact
required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. 

(g) Furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to this Section 2, on the date that
such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 2, if such securities are being sold through underwriters, or, if such securities are not being sold through
underwriters, on the date that the registration statement with respect to such securities becomes effective, (i) an opinion, dated such date, of the outside counsel representing the Company for the purposes of such registration, in form and
substance as is customarily given to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities and (ii) a letter dated such date, from the
independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the
Holders requesting registration of Registrable Securities. 
 (h) Provide a transfer agent and registrar for all Registrable Securities
registered pursuant to such registration statement and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 

(i) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed. 
 (j) In connection with any underwritten offering pursuant to a registration statement filed
pursuant to Section 2.2, enter into an underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided such underwriting agreement 

 
contains reasonable and customary provisions, and provided further, that each Holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

 2.5 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this
Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such customary information regarding itself, the Registrable Securities held by it, and the intended method of disposition
of such securities as shall be required to effect the registration of such Holder’s Registrable Securities. 
 2.6 Expenses of
Demand Registration. All expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Section 2.2, including (without limitation), all registration, filing and
qualification fees, printers and accounting fees, fees and disbursements of counsel for the Company, and the reasonable fees and disbursements of one counsel for the selling Holders shall be borne by the Company with respect to such registrations;
provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.2 if the registration request is subsequently withdrawn at the request of a majority in interest of the
Initiating Holders, if such request was a Preferred Demand, or a majority in interest of the Series D Initiating Holders, if such request was a Series D Demand (in which case all participating Holders shall bear such expenses) unless a majority in
interest of the Initiating Holders, if such request was a Preferred Demand, or a majority in interest of the Series D Initiating Holders, if such request was a Series D Demand, agrees to forfeit their right to the demand registration pursuant to
Section 2.2; provided further, however, that if at the time of such withdrawal, (i) the Holders have learned of a material and adverse change in the condition, business, or prospects of the Company from that known to the Holders at the
time of their request or (ii) the underwriters indicated that the registration would have likely been a Cutback Registration, then the Holders shall not be required to pay any of such expenses and shall retain their rights pursuant to
Section 2.2. 
 2.7 Expenses of Company Registration. The Company shall bear and pay all expenses incurred in connection with
any registration, filing or qualification of Registrable Securities with respect to registrations pursuant to Section 2.3 for each Holder (which right may be assigned as provided in Section 2.14), including (without limitation) all
registration, filing, and qualification fees, printers and accounting fees relating or apportionable thereto and the fees and disbursements of one counsel for the selling Holders selected by them, but excluding underwriting discounts and commissions
relating to Registrable Securities. 
 2.8 Underwriting Requirements. In connection with any offering involving an underwriting of
shares being issued by the Company, the Company shall not be required under Section 2.3 to include any of the Holders’ securities in such underwriting unless they accept the terms of the underwriting as agreed upon between the Company and
the underwriters selected by it (provided that such underwriters shall be of nationally recognized reputation), and then only in such quantity as will not, in the opinion of the underwriters, jeopardize the success of the offering by the Company. If
the total amount of securities, including Registrable Securities, requested by shareholders to be included in such offering exceeds the amount of securities sold other than by the 

 
Company that the underwriters reasonably believe compatible with the success of the offering, then the Company shall be required to include in the offering only that number of such securities,
including Registrable Securities, which the underwriters believe will not jeopardize the success of the offering (the securities so included to be apportioned pro rata (i) first among the selling shareholders holding Registrable
Securities and (ii) second among selling shareholders holding other equity securities. In no event shall the amount of securities of the selling Holders included in the offering be reduced below twenty percent (20%) of the total
amount of securities included in such offering, unless such offering is the Company’s first firm commitment underwritten public offering of the Company’s securities registered under the Act (the “Initial Public Offering”),
in which case the selling shareholders may be excluded if the underwriters make the determination described above and no other shareholder’s securities are included. Notwithstanding the foregoing, the Company shall not include in any
registration pursuant to this Section 2.3 that is an underwritten offering any securities that are held by an employee of the Company or any of its subsidiaries or any person controlled by any such employee without the prior written consent of
the underwriters. For purposes of the preceding parenthetical concerning apportionment, for any selling shareholder which is a holder of Registrable Securities and which is a partnership or corporation, the partners, retired partners and
shareholders of such holder, or the estates and family members of any such partners and retired partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling shareholder,” and any
pro rata reduction with respect to such “selling shareholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “selling
shareholder,” as defined in this sentence. 
 2.9 Delay of Registration. No Holder shall have any right to obtain or seek an
injunction restraining or otherwise delaying any such registration as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

2.10 Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 2: 

(a) To the fullest extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter (as defined in the Act)
for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Act or the Securities Exchange Act of 1934, as amended (the “1934 Act”), against any losses, claims, damages, or liabilities
(joint or several) to which they may become subject under the Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereof) arise out of or are based upon any of the
following statements, omissions or violations (collectively a “Violation”): (i) any untrue statement or alleged untrue statement of a material fact contained or incorporated by reference in such registration statement,
including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, any issuer free writing prospectus (as defined in Rule 433 of the Act), any issuer information (as defined in Rule 433 of the Act)
filed or required to be filed pursuant to Rule 433(d) under the Act or any other document incident to any such registration, qualification or compliance prepared by or on behalf of the Company or used or referred to by the Company, (ii) the
omission or alleged omission to state therein a material fact required to be stated therein, or necessary to make the statements 

 
therein not misleading, or (iii) any violation or alleged violation by the Company of the Act, the 1934 Act, any state securities law or any rule or regulation promulgated under the Act, the
1934 Act or any state securities law; and the Company will pay as incurred to each such Holder, underwriter or controlling person, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss,
claim, damage, liability, or action; provided that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability, or action arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by such Holder or underwriter and stated to be specifically for use therein; and provided further that the indemnity agreement contained in this subsection 2.10(a) shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability, or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld), nor shall the Company be liable in any such case for any such loss, claim,
damage, liability, or action to the extent that it arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such
Holder, underwriter or controlling person. 
 (b) To the extent permitted by law, each selling Holder, severally (and not jointly and
severally), will indemnify and hold harmless the Company, each of its directors, each of its officers who has signed the registration statement, each person, if any, who controls the Company within the meaning of the Act, any underwriter, any other
Holder selling securities in such registration statement and any controlling person of any such underwriter or other Holder, against any losses, claims, damages, or liabilities (joint or several) to which any of the foregoing persons may become
subject, under the Act, the 1934 Act or other federal or state law, insofar as such losses, claims, damages, or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with written information furnished by such Holder expressly for use in connection with such registration; and each such Holder will pay, as incurred, any legal or other expenses
reasonably incurred by any person intended to be indemnified pursuant to this subsection 2.10(b), in connection with investigating or defending any such loss, claim, damage, liability, or action; provided, however, that the indemnity agreement
contained in this subsection 2.10(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably
withheld; provided that in no event shall any indemnity under this subsection 2.10(b) exceed the net proceeds from the offering received by such Holder, except in the case of fraud by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 2.10 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this Section 2.10, deliver to the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the
parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the
indemnifying party 

 
would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the commencement of any such action, if prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified party under this
Section 2.10, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 2.10. No indemnifying party, in the
defense of any such claim or litigation, shall, except with the consent of each indemnified party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or
plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. Each indemnified party shall furnish such information regarding itself or the claim in question as an indemnifying party may reasonably
request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom. 
 (d)
If the indemnification provided for in this Section 2.10 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any loss, liability, claim, damage, or expense referred to therein, then the
indemnifying party, in lieu of indemnifying such indemnified party hereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such loss, liability, claim, damage, or expense in such proportion as is
appropriate to reflect the relative fault of the indemnifying party on the one hand and of the indemnified party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as
any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or
omission. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 

(e) Notwithstanding the foregoing, to the extent that the provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are in conflict with the foregoing provisions, as between the Company and the underwriters only, the provisions in the underwriting agreement shall control. 

(f) The obligations of the Company and Holders under this Section 2.10 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 2, and otherwise. 
 2.11 Restrictions on Transfer. 

(a) The holder of each certificate representing Registrable Securities by acceptance thereof agrees to comply in all respects with the
provisions of this Section 2.11. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Registrable Securities, or any beneficial interest therein, unless and until the transferee

 
thereof has agreed in writing for the benefit of the Company to take and hold such Registrable Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement,
including, without limitation, this Section 2.11 and Section 2.16, and: 
 (i) There is then in effect a registration statement
under the Act covering such proposed disposition and the disposition is made in accordance with the registration statement; or 
 (ii) The
Holder shall have given prior written notice to the Company of the Holder’s intention to make such disposition, and the Holder shall have furnished the Company, at the Holder’s expense, with (i) an opinion of counsel reasonably
satisfactory to the Company to the effect that such disposition will not require registration of such Registrable Securities under the Act or (ii) a “no action” letter from the Commission to the effect that the transfer of such
securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Registrable Securities shall be entitled to transfer such Registrable
Securities in accordance with the terms of the notice delivered by the Holder to the Company, whereupon the holder of such Registrable Securities shall be entitled to transfer such Registrable Securities in accordance with the terms of the notice
delivered by the Holder to the Company. 
 (b) Notwithstanding the provisions of Section 2.11(a), no such registration statement or
opinion of counsel or “no action” letter shall be necessary for (i) a transfer not involving a change in beneficial ownership, (ii) customary transfers pursuant to Rule 144 of the Act or (iii) transactions involving the
distribution without consideration of Registrable Securities by any Holder to (x) a parent, subsidiary or other affiliate of the Holder, if the Holder is a corporation or other entity, (y) any of the Holder’s partners, members or
other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of the Holder’s partners, members or other equity owners or retired partners, retired members or other equity owners, or (z) a person
that is controlled by or under common control with one or more general partners or managing members of, or shares the same management company with, the Holder; provided, in each case, that the Holder shall give written notice to the Company
of the Holder’s intention to effect such disposition. 
 (c) Each certificate representing Registrable Securities shall (unless
otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws): 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER
THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION
THEREFROM. THE ISSUER OF THESE SECURITIES 

 
MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE
SECURITIES LAWS. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A
LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS AGREEMENT, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. 

The Holders consent to the Company making a notation on its records and giving instructions to any transfer agent of the Registrable
Securities in order to implement the restrictions on transfer established in this Section 2.11. 
 (d) The first legend referring to
federal and state securities laws identified in Section 2.11(c) stamped on a certificate evidencing the Registrable Securities and the stock transfer instructions and record notations with respect to the Registrable Securities shall be removed
and the Company shall issue a certificate without such legend to the holder of Registrable Securities if (i) those securities are registered under the Act, or (ii) the holder provides the Company with a certificate to the effect that a
sale or transfer of those securities may be made without registration or qualification. 
 2.12 Reports Under Securities Exchange Act of
1934. With a view to making available to the Holders the benefits of Rule 144 promulgated under the Act and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to: 
 (a) make and keep public information available, as
those terms are understood and defined in SEC Rule 144, at all times after ninety (90) days after the effective date of the Initial Public Offering; 

(b) take such action, including the voluntary registration of its Common Stock under Section 12 of the 1934 Act, as is necessary to
enable the Holders to utilize Form S-3 for the sale of their Registrable Securities, such action to be taken as soon as practicable after the end of the fiscal year following the effective date of the Initial Public Offering; 

(c) file with the SEC in a timely manner all reports and other documents required of the Company under the Act and the 1934 Act; and 

(d) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) a certificate by an officer
of the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by the Company), the Act and the 1934 Act (at

 
any time after it has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any time after it so
qualifies), (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company, and (iii) such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC which permits the selling of any such securities without registration or pursuant to such form. 
 2.13
Form S-3 Registration. In case the Company shall receive from any Holder or Holders of the Registrable Securities a written request or requests that the Company effect a registration on Form S-3 and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by such Holder or Holders, the Company will: 
 (a) promptly
give written notice of the proposed registration, and any related qualification or compliance, to all other Holders; and 
 (b) as soon as
practicable, effect such registration and all such qualifications and compliances as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities
as are specified in such request, together with all or such portion of the Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such
written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration, qualification or compliance, pursuant to this Section 2.13, (i) if Form S-3 is not legally available for such
offering by the Holders; (ii) if the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate
price to the public (net of any underwriters’ discounts or commissions) of less than $1,000,000; or (iii) if the Company shall furnish to the Holders a certificate signed by the president of the Company stating that in the good faith
judgment of the Board of Directors of the Company it would be materially and adversely detrimental to the Company and its shareholders for such Form S-3 Registration to be effected at such time, in which event the Company shall have the right
to defer the filing of the Form S-3 registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 2.13; provided, however, that the Company shall not
utilize this right more than once in any twelve (12) month period. If for any reason the Company ceases to be a WKSI or becomes ineligible to utilize Form S-3, then the Company shall prepare and file with the Securities and Exchange Commission
one or more registration statements on such form that is available for the sale of Registrable Securities. All registrations pursuant to this Section 2.13 shall be underwritten registrations unless otherwise approved by the holders of a
majority of the Registrable Securities initially requesting registration. 
 (c) Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other securities so requested to be registered as soon as practicable after receipt of the request or requests of the Holders. All expenses other than underwriting discounts and
commissions incurred in connection with a registration requested pursuant to this Section 2.13, including (without limitation) all registration, filing, qualification, 

 
printer’s and accounting fees and the reasonable fees and disbursements of counsel for the Company and one counsel for the selling Holder or Holders, shall be borne by the Company; provided,
however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to this Section 2.13 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (in which case all participating Holders shall bear such expenses), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to the registration under this Section 2.13
for a six (6) month period; provided further, however, that if at the time of such withdrawal, (i) the Holders have learned of a material adverse change in the condition or business of the Company from that known to the Holders at the time
of their request or (ii) the underwriters indicated that the registration would have likely not included at least 75% of such Registrable Securities requested to be included in such registration, then the Holders shall not be required to pay
any of such expenses and shall retain their rights pursuant to this Section 2.13 for such a six (6) month period. 
 (d) The
Company is obligated to effect an unlimited number of registrations pursuant to this Section 2.13 and registrations effected pursuant to this Section 2.13 shall not be counted as demand registrations under Section 2.2 or 2.3. 

2.14 Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this
Section 2 may be assigned by a Holder to a transferee or assignee of at least 100,000 shares of such securities provided the Company is, within a reasonable time after such transfer, furnished with written notice of the name and address of such
assignee and the securities with respect to which such registration rights are being assigned. The foregoing 100,000 share limitation shall not apply, however, to transfers by a Holder to affiliates, shareholders, partners or retired partners of the
Holder (including spouses and ancestors, lineal descendants and siblings of such partners or spouses who acquire Registrable Securities by gift, will or intestate succession) if all such transferees or assignees agree in writing to appoint a single
representative as their attorney in fact for the purpose of receiving any notices and exercising their rights under this Section 2. 

2.15 Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior
written consent of the Holders of a majority of the outstanding Registrable Securities, enter into any agreement with any holder or prospective holder of any securities of the Company which would allow such holder or prospective holder (a) to
hold registration rights with respect to such securities unless such new registration rights, including standoff obligations, are subordinate to the registration rights granted Holders under this Agreement; or (b) to make a demand registration
which could result in such registration statement being declared effective prior to the earlier of either of the dates set forth in subsection 2.2(a) or within one hundred eighty (180) days of the effective date of any registration effected
pursuant to Section 2.2. 
 2.16 “Market Stand-Off” Agreement. 

(a) Initial Public Offering. Each Holder hereby agrees that during the period of duration (up to, but not exceeding 180 days) specified by
the Company and the lead 

 
underwriter following the effective date of the Initial Public Offering, it shall not, to the extent requested by the underwriter, sell or otherwise transfer, make any short sale of, grant any
option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale (other than with respect to transfers pursuant to Section 2.11(b)) any Common Stock of the Company held by it at any time
during such period except Common Stock included in such registration; provided, however, that such Holder’s obligation under this Section 2.16(a) shall be subject to Company causing each officer, director and all other persons with
registration rights (whether or not pursuant to this Agreement) to enter into a similar agreement. 
 (b) Other Public Offerings. If a
majority of the holders of Series D Preferred Stock agree (in their sole discretion) that during the period of duration (up to, but not exceeding 90 days) specified by the Company and the lead underwriter following the effective date of a
registration statement of the Company filed under the Act which covers the registration of the Registrable Securities, other than a registration statement filed in connection with the Initial Public Offering, then each Holder agrees that it shall
not, to the extent requested by the underwriter, sell or otherwise transfer, make any short sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale (other than with
respect to transfers pursuant to Section 2.11(b)) any Common Stock of the Company at any time during such period except Common Stock included in such registration, and the Company shall use commercially reasonable efforts to cause each officer,
director and holder of 5% of the equity of the Company and all other persons with registration rights (whether or not pursuant to this Agreement) to enter into a similar agreement. 

To enforce the foregoing covenants, the Company may impose stop-transfer instructions with respect to the Registrable Securities of the Holder
(and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. If required pursuant to this Agreement, each Holder agrees to execute a market standoff agreement with said underwriters in
customary form consistent with the provisions of this Section 2.16. 
 2.17 Subsidiary Public Offering. If, after an initial
public offering of the capital stock or other equity securities of one of the Company’s subsidiaries, the Company distributes securities of such subsidiary to its equity holders, then the rights of Holders hereunder and the obligations of the
Company pursuant to this Agreement shall apply, mutatis mutandis, to such subsidiary, and the Company shall cause such subsidiary to comply with such subsidiary’s obligations under this Agreement. 

Section 3. Information Rights.

3.1 Delivery of Financial Statements.

(a) The Company shall deliver to each Holder, as soon as practicable, but in any event within ninety (90) days after the end of each
fiscal year of the Company, an income statement for such fiscal year, a balance sheet of the Company as of the end of such year, and statements of income and cash flows for such year, such year-end financial reports to be in reasonable detail,
prepared in accordance with generally accepted accounting principles (“GAAP”), 

 
and, if deemed appropriate by the Board of Directors, audited and certified by independent public accountants of nationally recognized standing selected by the Company. 

(b) The Company shall deliver to each Major Investor: 

(i) as soon as practicable, but in any event within forty-five (45) days after the end of each of the first three (3) fiscal
quarters of each fiscal year of the Company, a balance sheet of the Company as of the end of each such quarterly period, and statements of income and cash flows for such period and for the current fiscal year to date, prepared in accordance with
GAAP, subject to changes resulting from normal year-end audit adjustments, all in reasonable detail and certified by the principal financial or accounting officer of the Company, except that such financial statements need not contain the notes
required by GAAP; 
 (ii) as soon as practicable, but in any event within thirty (30) days prior to the end of each fiscal year, a
budget and business plan for the next fiscal year, prepared on a monthly basis, including balance sheets and sources and applications of funds statements for such months and, as soon as prepared, any other budgets or revised budgets prepared by the
Company; and 
 (iii) such other information relating to the financial condition, business, prospects or corporate affairs of the Company
as the Holder may from time to time request. 
 3.2 Termination of Financial Statement Rights. The covenants set forth in
Section 3.1 shall terminate as to the Holders and be of no further force or effect (i) immediately upon the consummation of the Company’s Initial Public Offering in which all shares of the Company’s Series D Preferred Stock are
converted to Common Stock or (ii) when the Company is required to file reports pursuant to Section 13 or 15(d) of the 1934 Act. 

3.3 Confidentiality. Anything in this Agreement to the contrary notwithstanding, no Holder by reason of this Agreement shall have
access to any trade secrets of the Company not shared with other Holders (in their capacity as Holders). Each Holder acknowledges that the information received by it pursuant to this Agreement may be confidential and for its use only, and it will
not reproduce, disclose or disseminate such confidential information in violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than its employees or agents having a need to know the contents
of such information, and its attorneys), except in connection with the exercise of rights under this Agreement, unless the Company has made such information available to the public generally. Notwithstanding the foregoing, each Holder may include
summary financial information concerning the Company and general statements concerning the nature and progress of the Company’s business in such Holder’s reports to its limited partners. 

Section 4. Right of First Refusal. 

4.1 Right of First Refusal to Major Series D Investors. The Company hereby grants to each Major Series D Investor, the right of first
refusal to purchase its pro rata share of New Securities (as defined in Section 4.1(a)) which the Company may, from time to time, propose to sell 

 
and issue after the date of this Agreement. A Major Series D Investor’s pro rata share, for purposes of this right of first refusal, is equal to the ratio of (a) the number of
shares of Common Stock owned by such Major Series D Investor immediately prior to the issuance of New Securities (assuming full conversion of the Preferred Stock and full conversion or exercise of all outstanding convertible securities, rights,
options and warrants held by said Major Series D Investor, to the extent such securities are “in-the-money”) to (b) the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities (assuming
full conversion of the Preferred Stock and full conversion or exercise of all outstanding convertible securities, rights, options and warrants, to the extent such securities are “in-the-money”). 

(a) “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company or any of
its subsidiaries whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible into capital stock;
provided that the term “New Securities” does not include any securities of the Company that do not constitute “Additional Stock” (as defined in the Company’s Amended and Restated Articles of
Incorporation, as amended from time to time). 
 (b) In the event the Company proposes to undertake an issuance of New Securities, it shall
give each Major Series D Investor written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Major Series D Investor shall have thirty
(30) days after any such notice is mailed or delivered to agree to purchase such Holder’s pro rata share of such New Securities and to indicate whether such Holder desires to exercise its
over-allotment option for the price and upon the terms specified in the notice by giving written notice to the Company, in substantially the form attached as Schedule 1, and stating therein the quantity
of New Securities to be purchased. 
 (c) In the event the Holders fail to exercise fully the right of first refusal and over-allotment rights, if any within said thirty (30) day period (the “Election Period”), the Company shall have thirty (30) days thereafter to sell or enter into an agreement (pursuant to
which the sale of New Securities covered thereby shall be closed, if at all, within thirty (30) days from the date of said agreement) to sell that portion of the New Securities with respect to which the Major Series D Investors’ right of
first refusal option set forth in this Section 4.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Major Series D Investors delivered pursuant to
Section 4.1(b). In the event the Company has not sold within such thirty (30) day period following the Election Period, or such thirty (30) day period following the date of said agreement, the Company shall not thereafter issue or
sell any New Securities, without first again offering such securities to the Major Series D Investors in the manner provided in this Section 4.1. 

(d) The right of first refusal granted under this Agreement shall expire upon the consummation of the Company’s Initial Public Offering
in which all shares of the Company’s Series D Preferred Stock are converted to Common Stock. 

 Section 5. Miscellaneous. 

5.1 Successors and Assigns. The provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors,
assigns, heirs, executors and administrators of the parties hereto. 
 5.2 Third Parties. Nothing in this Agreement, express or
implied, is intended to confer upon any party, other than the parties hereto, and their respective successors and assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein.

 5.3 Governing Law. This Agreement shall be governed in all respects by the internal laws of the State of California as applied to
agreements entered into among California residents to be performed entirely within California, without regard to principles of conflicts of law. 

5.4 Counterparts. This Agreement and any amendments hereto may be executed in any number of counterparts, each of which shall be
enforceable against the parties that execute such counterparts, and all of which together shall constitute one instrument. 
 5.5
Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by facsimile or electronic mail or otherwise delivered by hand,
messenger or courier service addressed: 
 (a) if to an Investor, to the Investor’s address, facsimile number or electronic mail
address as shown on Exhibit A hereto, as may be updated in accordance with the provisions hereof, with a copy (which shall not constitute notice) to the counsel set forth on the signature pages hereto; 

(b) if to any other Holder, to such address, facsimile number or electronic mail address as shown in the Company’s records, or, until
any such Holder so furnishes an address, facsimile number or electronic mail address to the Company, then to the address of the last holder of such shares for which the Company has contact information in its records; or 

(c) if to the Company, to the attention of the President the Company at 3 W. Plumeria Dr., San Jose, CA 95134, or at such other current
address as the Company shall have furnished to the Investors or Holders, with a copy (which shall not constitute notice) to Herbert Fockler and Mark Baudler, Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, CA 94304.

 Each such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given (i) if
delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one business day after deposit with the courier), or
(ii) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained 

 
receptacle for the deposit of the United States mail, addressed and mailed as aforesaid, or (iii) if sent via facsimile, upon confirmation of facsimile transfer or, if sent via electronic
mail, upon confirmation of delivery when directed to the relevant electronic mail address if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business
day. In the event of any conflict between the Company’s books and records and this Agreement or any notice delivered hereunder, the Company’s books and records will control absent fraud or error. 

5.6 Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, portions of such provision, or such provision in its entirety, to the extent necessary, shall be severed from this Agreement, and such court will replace such illegal, void or unenforceable provision of this Agreement with a
valid and enforceable provision that will achieve, to the extent possible, the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Agreement shall be enforceable in accordance with its
terms. 
 5.7 Amendment. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended, waived,
discharged or terminated other than by a written instrument referencing this Agreement and signed by the Company and the Holders holding a majority of the Registrable Securities (excluding any of such shares that have been sold to the public or
pursuant to Rule 144, and excluding, with respect to Section 2 (other than Sections 2.11, 2.12 and 2.16), any of such shares held by any Holders whose rights to request registration or inclusion in any registration pursuant to
Section 2 have terminated in accordance with Section 2.17); provided, however, that this Agreement may not be amended, waived, discharged or terminated in any manner that adversely impacts any Series D Investor without the
consent of Series D Investors holding a majority of the shares of Series D Preferred Stock; provided further, however, that Brocade Communications Systems, Inc. or its affiliates (or their designees) (“Brocade”) may be added
as an Investor under this Agreement without any further consent of the Holders upon the issuance of Additional Brocade Stock (as defined in the Company’s Articles of Incorporation), but only to the extent that such party is issued Additional
Brocade Stock. To become a party to this Agreement pursuant to the prior sentence, Brocade shall execute a counterpart to this Agreement. Any such amendment, waiver, discharge or termination effected in accordance with this paragraph shall be
binding upon each Holder and each future holder of all such securities of Holder. Each Holder acknowledges that by the operation of this paragraph, the holders of a majority of the Registrable Securities (excluding any of such shares that have been
sold to the public or pursuant to Rule 144, and excluding, with respect to Section 2 (other than Sections 2.11, 2.12 and 2.16), any of such shares held by any Holders whose rights to request registration or inclusion in any registration
pursuant to Section 2 have terminated in accordance with Section 2.17) will have the right and power to diminish or eliminate all rights of such Holder under this Agreement. 

5.8 Rights of Holders. Each Holder of Registrable Securities shall have the absolute right to exercise or refrain from exercising
any right or rights that such Holder may have by reason of this Agreement, including, without limitation, the right to consent to the waiver or modification of any obligation under this Agreement, and such Holder shall not incur any liability to

 
any other holder of any securities of the Company as a result of exercising or refraining from exercising any such right or rights. 

5.9 Entire Agreement. This Agreement and the exhibits hereto constitute the full and entire understanding and agreement between the
parties with regard to the subjects hereof and supersedes in its entirety the Prior Rights Agreement, which shall have no further force and effect. No party hereto shall be liable or bound to any other party in any manner with regard to the subjects
hereof or thereof by any warranties, representations or covenants except as specifically set forth herein. 
 5.10 Delays or
Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to any party to this Agreement upon any breach or default of any other party under this Agreement shall impair any such
right, power or remedy of such non-defaulting party, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring, nor shall any waiver of any
single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement,
or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or
otherwise afforded to any party to this Agreement, shall be cumulative and not alternative. 
 5.11 Titles and Subtitles. The titles
and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. All references in this Agreement to sections, paragraphs and exhibits shall, unless otherwise provided,
refer to sections and paragraphs hereof and exhibits attached hereto. 
 5.12 Telecopy Execution and Delivery. A facsimile, telecopy
or other reproduction of this Agreement may be executed by one or more parties hereto and delivered by such party by facsimile or any similar electronic transmission device pursuant to which the signature of or on behalf of such party can be seen.
Such execution and delivery shall be considered valid, binding and effective for all purposes. At the request of any party hereto, all parties hereto agree to execute and deliver an original of this Agreement as well as any facsimile, telecopy or
other reproduction hereof. No party hereto shall raise the use of a facsimile machine or electronic transmission in pdf to deliver a signature or the fact that any signature or document was transmitted or communicated through the use of facsimile
machine as a defense to the formation of a contract, and each such party forever waives any such defense. 
 5.13 Jurisdiction;
Venue. With respect to any disputes arising out of or related to this Agreement, the parties consent to the exclusive jurisdiction of, and venue in, the state courts in Santa Clara County in the State of California (or in the event of exclusive
federal jurisdiction, the courts of the Northern District of California). 
 5.14 Further Assurances. Each party hereto agrees
to execute and deliver, by the proper exercise of its corporate, limited liability company, partnership or other powers, all such other 

 
and additional instruments and documents and do all such other acts and things as may be necessary to more fully effectuate this Agreement. 

5.15 Attorneys’ Fees. In the event that any suit or action is instituted to enforce any provision in this Agreement, the
prevailing party in such dispute shall be entitled to recover from the losing party such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals. 

5.16 Aggregation of Stock. All securities held or acquired by affiliated entities (including affiliated venture capital funds) or
persons shall be aggregated together for purposes of determining the availability of any rights under this Agreement. 
 5.17
Remedies. The Company acknowledges and agrees that the Investors would be damaged irreparably in the event any of the provisions of this Agreement are not performed in accordance with their specific terms or otherwise are breached and
money damages would not be an adequate remedy. Accordingly, in addition to the other remedies available to the Investors, the Company agrees that the Investors shall be entitled to an injunction or injunctions to prevent breaches of the provisions
of this Agreement and to enforce specifically this Agreement and the terms and provisions hereof (without the posting of bond or other security) in any action instituted in any court of the United States or any state thereof having jurisdiction over
the parties and the matter. 
 5.18 Jury Trial. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT
PERMITTED BY LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING (WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATED TO THIS AGREEMENT. If the waiver of jury trial set forth in this section is not enforceable,
then any claim or cause of action arising out of or relating to this Agreement shall be settled by judicial reference pursuant to California Code of Civil Procedure Section 638 et seq. before a referee sitting without a
jury, such referee to be mutually acceptable to the parties or, if no agreement is reached, by a referee appointed by the Presiding Judge of the California Superior Court for Santa Clara County. This paragraph shall not restrict a party from
exercising remedies under the Uniform Commercial Code or from exercising pre-judgment remedies under applicable law.

 Exhibit 10.1 

A10 NETWORKS, INC. 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is dated as of
[            , 20    ] (the “Effective Date”), and is between A10 Networks, Inc., a Delaware corporation (the “Company”), and
[insert name of indemnitee] (“Indemnitee”). 
 RECITALS 

A. Indemnitee’s service to the Company substantially benefits the Company. 

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

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

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

(a) A “Change in Control” shall be deemed to occur upon the earliest to occur after the date of this Agreement of any
of the following events: 
 (i) Acquisition of Stock by Third Party. Any Person (as defined below) is or becomes the Beneficial
Owner (as defined below), directly or indirectly, of securities of the Company representing [thirty percent (30%)] or more of the combined voting power of the Company’s then outstanding securities; 

(ii) Change in Board Composition. During any period of two (2) consecutive years (not including any period prior to the Effective
Date), individuals who at the beginning of such period constitute the Company’s board of directors, and any new directors (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction
described in Sections 1(a)(i), 1(a)(iii) or 1(a)(iv)) whose election by the board of directors or nomination for election by the Company’s stockholders was approved by a vote of at least [a majority] of the directors then-still in office,
who either were directors at the beginning of the period or whose election or nomination for election was 

 
previously so approved, cease for any reason to constitute at least a majority of the members of the Company’s board of directors; 

(iii) Corporate Transactions. A merger or consolidation of the Company with any other entity, other than a merger or consolidation
which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity)
[at least two thirds (2/3)] of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation [and with the power to elect at least a majority of the board of directors or other
governing body of such surviving entity]; 
 (iv) Liquidation. The approval by the stockholders of the Company of a complete
liquidation of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company’s assets; and 

(v) Other Events. Any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of
Regulation 14A (or in response to any similar item on any similar schedule or form) promulgated under the Securities Exchange Act of 1934, as amended, whether or not the Company is then subject to such reporting requirement. 

For purposes of this Section 1(a), the following terms shall have the following meanings: 

(1) “Person” shall have the meaning as set forth in Sections 13(d) and 14(d) of the Securities Exchange Act of
1934, as amended; provided, however, that “Person” shall exclude (i) the Company, (ii) any trustee or other fiduciary holding securities under an employee benefit plan of the Company, and (iii) any
corporation owned, directly or indirectly, by the stockholders of the Company in substantially the same proportions as their ownership of stock of the Company. 

(2) “Beneficial Owner” shall have the meaning given to such term in Rule 13d-3 under the Securities Exchange Act
of 1934, as amended; provided, however, that “Beneficial Owner” shall exclude any Person otherwise becoming a Beneficial Owner by reason of (i) the stockholders of the Company approving a merger of the Company
with another entity or (ii) the Company’s board of directors approving a sale of securities by the Company to such Person. 
 (b)
“Corporate Status” describes the status of a person who is or was a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company or any other Enterprise. 

(c) “DGCL” means the General Corporation Law of the State of Delaware. 

(d) “Disinterested Director” means a director of the Company who is not and was not a party to the Proceeding in
respect of which indemnification is sought by Indemnitee. 
 (e) “Enterprise” means the Company and any other
corporation, partnership, limited liability company, joint venture, trust, employee benefit plan or other enterprise of which Indemnitee is or was serving at the request of the Company as a director, trustee, general partner, managing member,
officer, employee, agent or fiduciary. 
 (f) “Expenses” include all attorneys’ fees, retainers, court costs,
transcript costs, fees and costs of experts, witness fees, travel expenses, duplicating costs, printing and binding costs, telephone charges, 

  
 -2- 

 
postage, delivery service fees, and all other disbursements or expenses actually and reasonably, and of the types customarily, incurred by Indemnitee, or on his or her behalf, in connection with
prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing to be a witness in, or otherwise participating in, a Proceeding. Expenses also include (i) Expenses incurred in connection with any appeal resulting
from any Proceeding, including without limitation the premium, security for, and other costs relating to any cost bond, supersedeas bond or other appeal bond or their equivalent, and (ii) for purposes of Section 12(d), Expenses incurred by
Indemnitee in connection with the interpretation, enforcement or defense of Indemnitee’s rights under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company [at any time]. Expenses,
however, shall not include amounts paid in settlement by Indemnitee or the amount of judgments or fines against Indemnitee. 
 (g)
“Independent Counsel” means a law firm, or a partner or member of a law firm, that is experienced in matters of corporation law and neither currently is, as of the time the request for indemnification is made nor in the
previous five (5) years has been, retained to represent (i) the Company or Indemnitee in any matter material to either such party (other than as Independent Counsel with respect to matters concerning Indemnitee under this Agreement, or
other indemnitees under similar indemnification agreements), or (ii) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel”
shall not include any person who, under the applicable standards of professional conduct then-prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s rights under
this Agreement. 
 (h) “Proceeding” means any threatened, pending or completed action, suit, arbitration, mediation,
alternate dispute resolution mechanism, investigation, inquiry, administrative hearing or proceeding, or claim, issue or matter therein, whether brought in the right of the Company, a Subsidiary or otherwise, and whether of a civil, criminal,
administrative or investigative nature, including any appeal therefrom, and including without limitation any such Proceeding pending as of the Effective Date, in which Indemnitee was, is or will be involved as a party, a potential party, a non-party
witness or otherwise by reason of (i) the fact that Indemnitee is or was a director or officer of the Company or of a Subsidiary, or (ii) the fact or assertion that he or she is or was serving at the request of the Company or of a
Subsidiary as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of the Company, a Subsidiary or any other Enterprise, in each case whether or not serving in such capacity at the time any liability or
Expense is incurred for which indemnification or advancement of expenses can be provided under this Agreement. 
 (i)
“Subsidiary” means any entity of which more than 50% of the outstanding voting securities is owned directly or indirectly by the Company. 

(j) Reference to “other enterprises” shall include employee benefit plans; references to
“fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director,

acted in good faith and in a manner he or she reasonably believed to be in the best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests
of the Company” as referred to in this Agreement. 
 2. Indemnity in Third-Party Proceedings. The Company shall
indemnify Indemnitee in accordance with the provisions of this Section 2 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding, other than a Proceeding by or in the right of the Company to procure a
judgment in its favor. Pursuant to this Section 2, Indemnitee shall be indemnified to the fullest extent permitted by 

  
 -3- 

 
applicable law against all Expenses, judgments, fines and amounts paid in settlement [(if, and only if, such settlement is approved in advance by the Company, which approval shall not be
unreasonably withheld)] in connection with such Proceeding, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company and, with respect to any criminal action or
proceeding, had no reasonable cause to believe that his or her conduct was unlawful. 
 3. Indemnity in Proceedings by or in the Right of
the Company. The Company shall indemnify Indemnitee in accordance with the provisions of this Section 3 if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding by or in the right of the Company to
procure a judgment in its favor. Pursuant to this Section 3, Indemnitee shall be indemnified to the fullest extent permitted by applicable law against all Expenses in connection with such Proceeding, if Indemnitee acted in good faith and in a
manner he or she reasonably believed to be in or not opposed to the best interests of the Company. No indemnification for Expenses shall be made under this Section 3 in respect of any claim, issue or matter as to which Indemnitee shall have
been adjudged by a court of competent jurisdiction to be liable to the Company, unless and only to the extent that the Delaware Court of Chancery shall determine upon application that, despite the adjudication of liability but in view of all the
circumstances of the case, Indemnitee is fairly and reasonably entitled to indemnification for such expenses as the Delaware Court of Chancery shall deem proper. 

4. Indemnification for Expenses of a Party Who is Wholly or Partly Successful. To the extent that Indemnitee is a party to or a
participant in and is successful (on the merits or otherwise) in defense of any Proceeding or any claim, issue or matter therein, the Company shall indemnify Indemnitee against all Expenses in connection therewith. To the extent permitted by
applicable law, if Indemnitee is not wholly successful in such Proceeding but is successful, on the merits or otherwise, in defense of one or more but fewer than all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses in connection with (a) each successfully resolved claim, issue or matter and (b) to the fullest extent permitted by applicable law, any claim, issue or matter related to any such successfully resolved claim,
issuer or matter. For purposes of this Section 4, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such claim, issue or matter. 

5. Indemnification for Expenses of a Witness. To the extent that Indemnitee is, by reason of his or her Corporate Status, a witness in
any Proceeding to which Indemnitee is not a party, Indemnitee shall be indemnified to the extent permitted by applicable law against all Expenses in connection therewith. 

6. Additional Indemnification. 

(a) Notwithstanding any limitation in Sections 2, 3 or 4, above, the Company shall indemnify Indemnitee to the fullest extent permitted
by applicable law if Indemnitee is, or is threatened to be made, a party to or a participant in any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against all Expenses, judgments, fines and
amounts paid in settlement [(if, and only if, such settlement is approved in advance by the Company, which approval shall not be unreasonably withheld)] in connection with the Proceeding. 

(b) For purposes of Section 6(a), the meaning of the phrase “to the fullest extent permitted by
applicable law” shall include, but not be limited to: 
 (i) the fullest extent permitted by the
provision of the DGCL that authorizes or contemplates additional indemnification by agreement, or the corresponding provision of any amendment to or replacement of the DGCL; and 

  
 -4- 

 (ii) the fullest extent authorized or permitted by any amendments to or replacements of the DGCL
adopted after the date of this Agreement that increase the extent to which a corporation may indemnify its officers and directors. 
 7.
Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated under this Agreement to make any indemnity or provide any benefit to Indemnitee under this Agreement or otherwise, in connection with any
Proceeding (or any part of any Proceeding): 
 (a) for which payment has actually been made to or on behalf of Indemnitee under any statute,
insurance policy, indemnity provision, vote or otherwise, except with respect to any excess beyond the amount paid[, subject to any subrogation rights set forth in Section 15]1; 

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

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

8. Advances of Expenses. To the extent indemnity is provided pursuant to Sections 2, 3 or 4, above, or otherwise in this Agreement, the
Company shall advance the Expenses incurred by Indemnitee in connection with any such Proceeding, and such advancement shall be made as soon as reasonably practicable, but in any event no later than [30] days, after the receipt by the Company of a
written statement or statements requesting such advances from time to time (which shall include invoices received by Indemnitee in connection with such Expenses but, in the case of invoices in connection with legal services, any references to legal
work performed or to expenditure made that would cause Indemnitee to waive any privilege accorded by applicable law shall not be included with the invoice). Reimbursements hereunder shall be deemed advances, and shall be unsecured and interest free
and made without regard to Indemnitee’s ability to repay such advances. Indemnitee hereby undertakes to repay any such advance to the extent that it is ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This
Section 8 shall not apply to prevent reimbursement to the extent advancement is prohibited by law, or with respect to any Proceeding for which indemnity is not permitted under this Agreement, but shall apply to any Proceeding referenced in
Section 7(b) or 7(c) prior to a determination that Indemnitee is not entitled to be indemnified by the Company.

 9. Procedures for Notification and Defense of Claim. 

(a) Indemnitee shall notify the Company in writing of any matter with respect to which Indemnitee intends to seek indemnification or
advancement of Expenses as soon as reasonably practicable following the receipt by Indemnitee of notice thereof. The written notification to the Company shall include, in reasonable detail, a description of the nature of the Proceeding and the facts
underlying the Proceeding. The failure by Indemnitee to notify the Company will not relieve the Company from any liability which it may have to Indemnitee hereunder or otherwise than under this Agreement, and any delay in so notifying the Company
shall not constitute a waiver by Indemnitee of any rights, except to the extent that such failure or delay materially prejudices the Company. 

(b) If, at the time of the receipt of a written notice of a Proceeding pursuant to the terms hereof, the Company has directors’ and
officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of the Proceeding to such insurers in accordance with the procedures set forth in the applicable policies. The Company shall thereafter take all
commercially-reasonable actions to cause such insurers to pay, on behalf of Indemnitee, all amounts payable as a result of such Proceeding in accordance with the terms of such policies. 

(c) In the event the Company may be obligated to make any indemnity in connection with a Proceeding, the Company shall be entitled to assume
the defense of such Proceeding with counsel approved by Indemnitee, which approval shall not be unreasonably withheld, conditioned or delayed, upon the delivery to Indemnitee of written notice of the Company’s election to do so. After delivery
of such notice, approval of such counsel by Indemnitee and the retention of such counsel by the Company, the Company will not be liable to Indemnitee for any fees or expenses of counsel subsequently incurred by Indemnitee with respect to the same
Proceeding. Notwithstanding the Company’s assumption of the defense of any such Proceeding, the Company shall be obligated to pay the fees and expenses of Indemnitee’s counsel to the extent (i) the employment of counsel by Indemnitee
is authorized by the Company, (ii) counsel for the Company or Indemnitee shall have reasonably concluded that there is a conflict of interest between the Company and Indemnitee in the conduct of any such defense, such that Indemnitee needs to
be separately represented, (iii) the fees and expenses are non-duplicative and reasonably incurred in connection with Indemnitee’s role in the Proceeding despite the Company’s assumption of the defense, (iv) the Company is not
financially or legally able to perform its defense obligations, or (v) the Company shall not have retained, or shall not continue to retain, such counsel to defend such Proceeding; provided that Indemnitee’s counsel conducts the
defense of such Proceeding actively and diligently. The Company shall have the right to conduct such defense as it sees fit in its sole discretion. Regardless of any provision in this Agreement, Indemnitee shall have the right to employ counsel in
any Proceeding at Indemnitee’s personal expense. The Company shall not be entitled, without the consent of Indemnitee, to assume the defense of any claim brought by or in the right of the Company. 

(d) Indemnitee shall give the Company such information and cooperation in connection with the Proceeding as may be reasonably appropriate.

 (e) The Company shall not be liable to indemnify Indemnitee for any settlement of any Proceeding (or any part thereof) without the
Company’s prior written consent, which shall not be unreasonably withheld. 
 (f) The Company shall have the right to settle any
Proceeding (or any part thereof) without the consent of Indemnitee.

 10. Procedures upon Application for Indemnification. 

(a) To obtain indemnification, Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and
information as is reasonably available to Indemnitee and as is reasonably necessary or as the Company may reasonably request to determine whether and to what extent Indemnitee is entitled to indemnification following the final disposition of the
Proceeding. The Company shall, as soon as reasonably practicable after receipt of such a request for indemnification, advise the board of directors that Indemnitee has requested indemnification. Any delay in providing the request will not relieve
the Company from its obligations under this Agreement, except to the extent such failure is prejudicial. 
 (b) Upon written request by
Indemnitee for indemnification pursuant to Section 10(a), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in the specific case (i) if a Change in Control shall have
occurred, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be delivered to Indemnitee or (ii) if a Change in Control shall not have occurred, (A) by a majority vote of the
Disinterested Directors, even though less than a quorum of the Company’s board of directors, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors, even though less than a quorum of the
Company’s board of directors, (C) if there are no such Disinterested Directors, or if such Disinterested Directors so direct, by Independent Counsel in a written opinion to the Company’s board of directors, a copy of which shall be
delivered to Indemnitee, or (D) if so directed by the Company’s board of directors, by the stockholders of the Company. If it is so determined that Indemnitee is entitled to indemnification, payment to Indemnitee shall be made within ten
(10) days after such determination. Indemnitee shall cooperate with the person, persons or entity making the determination with respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity
upon reasonable advance request any documentation or information that is not privileged or otherwise protected from disclosure and that is reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses incurred by
Indemnitee in so cooperating with the person, persons or entity making such determination shall be borne by the Company, to the extent permitted by applicable law. 

(c) In the event the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 10(b), the
Independent Counsel shall be selected as provided in this Section 10(c). If a Change in Control shall not have occurred, the Independent Counsel shall be selected by the Company’s board of directors, and the Company shall give written
notice to Indemnitee advising him or her of the identity of the Independent Counsel so selected. If a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee shall request that such selection
be made by the Company’s board of directors, in which event the preceding sentence shall apply), and Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected. In either event,
Indemnitee or the Company, as the case may be, may, within ten days after such written notice of selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to such selection; provided,
however, that such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel,” as defined in Section 1 of this Agreement, and the objection
shall set forth with particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If such written objection is so made and substantiated, the Independent Counsel so
selected may not serve as Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within 20 days after the later of (i) submission by Indemnitee of a written request
for indemnification pursuant to Section 10(a) hereof and (ii) the final disposition of the Proceeding, the parties have not agreed upon an Independent Counsel, either the Company or Indemnitee may petition a court of competent jurisdiction
for resolution of any objection which shall have been made by the Company or Indemnitee to the other’s selection of Independent Counsel and for the appointment as Independent Counsel of 

  
 -7- 

 
a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as
Independent Counsel under Section 10(b), above. Upon the due commencement of any judicial proceeding or arbitration pursuant to Section 12(a), below, the Independent Counsel shall be discharged and relieved of any further responsibility in
such capacity (subject to the applicable standards of professional conduct then-prevailing). 
 (d) The Company agrees to pay the reasonable
fees and expenses of any Independent Counsel and to fully indemnify such counsel against any and all Expenses, claims, liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto. 

11. Presumptions and Effect of Certain Proceedings. 

(a) In making a determination with respect to entitlement to indemnification hereunder, the person, persons or entity making such
determination shall, to the fullest extent not prohibited by applicable law, presume that Indemnitee is entitled to indemnification if Indemnitee has submitted a request for indemnification in accordance with Section 10(a) of this Agreement,
and the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proof to overcome that presumption in connection with the making by such person, persons or entity of any determination contrary to that presumption.

 (b) The termination of any Proceeding, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its
equivalent, shall not (except as otherwise expressly provided in this Agreement or as required by applicable law) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith
and in a manner which he or she reasonably believed to be in or not opposed to the best interests of the Company or, with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his or her conduct was unlawful. 

(c) For purposes of any determination of good faith, Indemnitee shall be deemed to have acted in good faith to the extent Indemnitee relied in
good faith on (i) the records or books of account of the Enterprise, including financial statements, (ii) information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, (iii) the advice of legal
counsel for the Enterprise or its board of directors, or counsel selected by any committee of the board of directors, or (iv) information or records given or reports made to the Enterprise by an independent certified public accountant, an
appraiser, investment banker or other expert selected with reasonable care by the Enterprise or its board of directors or any committee of the board of directors (including consultants or advisors formally engaged by the board or committee). The
provisions of this Section 11(c) shall not be deemed to be exclusive or to limit in any way the other circumstances in which Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement. 

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

(a) Subject to Section 12(e), in the event that (i) a determination is made pursuant to Section 10, above, that Indemnitee is
not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 8, above, or 12(d), below, (iii) no determination of entitlement to indemnification shall have been made
pursuant to Section 10, above, within 90 days after the later of the receipt by the Company of the request for indemnification or the final disposition of the Proceeding, (iv) payment of indemnification pursuant to this Agreement is not
made (A) within ten (10) days 

  
 -8- 

 
after a determination has been made that Indemnitee is entitled to indemnification or (B) with respect to indemnification pursuant to Sections 4 or 5, above, and 12(d), below, within 30
days after receipt by the Company of a written request therefor, or (v) the Company or any other person or entity takes or threatens to take any action to declare this Agreement void or unenforceable, or institutes any litigation or other
action or proceeding to deny, or to recover from, Indemnitee the benefits provided or intended to be provided to Indemnitee hereunder, Indemnitee shall be entitled to an adjudication in a court of competent jurisdiction of his or her entitlement to
such indemnification or advancement of Expenses. Alternatively, Indemnitee, at his or her option, may seek an award in arbitration with respect to his or her entitlement to such indemnification or advancement of Expenses, to be conducted by a single
arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding seeking an adjudication or an award in arbitration within 180 days following the date on which Indemnitee
first has the right to commence such proceeding pursuant to this Section 12(a); provided, however, that the foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his or her rights under
Section 4, above. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration in accordance with this Agreement. 

(b) Neither (i) the failure of the Company, its board of directors, any committee or subgroup of the board of directors, Independent
Counsel or stockholders to have made a determination that indemnification of Indemnitee is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor (ii) an actual determination by the Company, its board of
directors, any committee or subgroup of the board of directors, Independent Counsel or stockholders that Indemnitee has not met the applicable standard of conduct, may be asserted or offered into evidence as a defense to the action or to create a
presumption that Indemnitee has or has not met the applicable standard of conduct. In the event that a determination shall have been made pursuant to Section 10 of this Agreement that Indemnitee is not entitled to indemnification, any judicial
proceeding or arbitration commenced pursuant to this Section 12 shall be conducted in all respects as a de novo trial, or arbitration, on the merits, and Indemnitee shall not be prejudiced by reason of that adverse determination. In any
judicial proceeding or arbitration commenced pursuant to this Section 12, the Company shall, to the fullest extent not prohibited by applicable law, have the burden of proving Indemnitee is not entitled to indemnification or advancement of
Expenses, as the case may be. 
 (c) To the fullest extent not prohibited by applicable law, the Company shall be precluded from asserting
in any judicial proceeding or arbitration commenced pursuant to this Section 12 that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court or before any such arbitrator
that the Company is bound by all the provisions of this Agreement. If a determination shall have been made pursuant to Section 10, above, that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any
judicial proceeding or arbitration commenced pursuant to this Section 12, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statements not materially
misleading, in connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law. 

(d) To the extent not prohibited by applicable law, the Company shall indemnify Indemnitee against all Expenses that are incurred by
Indemnitee in connection with any action for indemnification or advancement of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company to the extent
Indemnitee is successful in such action, and, if requested by Indemnitee, the Company shall (as soon as reasonably practicable, but in any event no later than 60 days, after receipt by the Company of a written request therefor) advance such Expenses
to Indemnitee, subject to the provisions of Section 8, above. 

  
 -9- 

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

15. [Primary Responsibility. The Company acknowledges that Indemnitee has certain rights to indemnification and advancement of expenses
provided by [insert name of fund] [and certain affiliates thereof] ([collectively,] the “Secondary Indemnitor[s]”). The Company agrees that, as between the Company and the Secondary Indemnitor[s], the Company is
primarily responsible for amounts required to be indemnified or advanced under the Company’s certificate of incorporation or bylaws or this Agreement and any obligation of the Secondary Indemnitor[s] to provide indemnification or advancement
for the same amounts is secondary to those Company obligations. To the extent not in contravention of any insurance policy or policies providing liability or other insurance for the Company or any director, trustee, general partner, managing member,
officer, employee, agent or fiduciary of the Company or any other Enterprise, the Company waives any right of contribution or subrogation against the Secondary Indemnitor[s] with respect to the liabilities for which the Company is primarily
responsible under this Section 15. In the event of any payment by the Secondary Indemnitor[s] of amounts otherwise required to be indemnified or advanced by the Company under the Company’s certificate of incorporation or bylaws or this
Agreement, the Secondary Indemnitor[s] shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee for indemnification or advancement of expenses under the Company’s certificate of incorporation or bylaws or
this Agreement or, to the extent such subrogation is unavailable and contribution is found to be the applicable remedy, shall have a right of contribution with respect to the amounts paid. The Secondary Indemnitor[s] [are][is an] express third-party
[beneficiaries][beneficiary] of the terms of this Section 15.]2 
  

	2 	Note to Draft: If there is no Secondary Indemnitor for the officer or director, delete this section and replace with “Reserved.” 

  
 -10- 

 16. No Duplication of Payments. The Company shall not be liable under this Agreement to
make any payment of amounts otherwise indemnifiable hereunder (or for which advancement is provided hereunder) if and to the extent that Indemnitee has otherwise actually received payment for such amounts under any insurance policy, contract,
agreement or otherwise[, subject to any subrogation rights set forth in Section 15]3. 

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

20. Duration. This Agreement shall commence as of the Effective Date and continue until and terminate upon the later of (a) ten
(10) years after the date that Indemnitee shall have ceased to serve as a director or officer of the Company or a Subsidiary, or as a director, trustee, general partner, managing member, officer, employee, agent or fiduciary of any other
Enterprise, as applicable, or (b) one (1) year after the final termination of any Proceeding, including any appeal, then-pending in respect of which Indemnitee is granted rights of indemnification or advancement of Expenses hereunder and
of any proceeding commenced by Indemnitee pursuant to Section 12, above, relating thereto. 
 21. Successors. This Agreement
shall be binding upon the Company and its successors and assigns, including any direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company, and shall inure to the
benefit of Indemnitee and Indemnitee’s heirs, executors and administrators. The Company shall require and cause any successor (whether direct or indirect by purchase, merger, consolidation or otherwise) to all or substantially all of the
business or assets of the Company, by written agreement, expressly to assume and agree to perform this Agreement in the 
  

	3 	 Note to Draft: Delete if Section 15 is deleted due to there being no Secondary Indemnitor.

  
 -11- 

 
same manner and to the same extent that the Company would be required to perform if no such succession had taken place. 

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

25. Modification and Waiver. No supplement, modification or amendment to this Agreement shall be binding unless and only to the extent
executed in writing by the parties hereto. No amendment, alteration or repeal of this Agreement shall adversely affect any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in his or her Corporate
Status prior to such amendment, alteration or repeal. No waiver of any of the provisions of this Agreement shall constitute or be deemed a waiver of any other provision of this Agreement nor shall any waiver constitute a continuing waiver. 

26. Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered
or certified mail, postage prepaid, sent by facsimile or electronic mail or otherwise delivered by hand, messenger or courier service addressed: 

(a) if to Indemnitee, to Indemnitee’s address, facsimile number or electronic mail address as shown on the signature page of this
Agreement or in the Company’s records, as may be updated in accordance with the provisions hereof; or 
 (b) if to the Company, to the
attention of the Chief Executive Officer or Chief Financial Officer of the Company at 3 West Plumeria Drive, San Jose, CA 95134, or at such other current address as the Company shall have furnished to Indemnitee, with copies (which shall not
constitute notice) to Mark Baudler, Esq. or Herb Fockler, Esq., Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304. 

  
 -12- 

 Each such notice or other communication shall for all purposes of this Agreement be treated as
effective or having been given (i) if delivered by hand, messenger or courier service, when delivered (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one business
day after deposit with the courier), (ii) if sent via mail, at the earlier of its receipt or five days after the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and mailed
as aforesaid, or (iii) if sent via facsimile, upon confirmation of facsimile transfer or, if sent via electronic mail, upon confirmation of delivery when directed to the relevant electronic mail address, if sent during normal
business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day. 

27. Applicable Law and Consent to Jurisdiction. This Agreement and the legal relations among the parties shall be governed by, and
construed and enforced in accordance with, the laws of the State of Delaware, without regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section 12(a), above, or by the Company or
Indemnitee pursuant to a written agreement between the Company and Indemnitee providing for such, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action or proceeding arising out of or in connection with
this Agreement shall be brought only in the Delaware Court of Chancery, and not in any other state or federal court in the United States of America or any court in any other country, (ii) consent to submit to the exclusive jurisdiction of the
Delaware Court of Chancery for purposes of any action or proceeding arising out of or in connection with this Agreement, (iii) appoint, to the extent such party is not otherwise subject to service of process in the State of Delaware,
Corporation Service Company, Wilmington, Delaware, as its agent in the State of Delaware as such party’s agent for acceptance of legal process in connection with any such action or proceeding against such party with the same legal force and
validity as if served upon such party personally within the State of Delaware, (iv) waive any objection to the laying of venue of any such action or proceeding in the Delaware Court of Chancery, and (v) waive, and agree not to plead or to
make, any claim that any such action or proceeding brought in the Delaware Court of Chancery has been brought in an improper or inconvenient forum. 

28. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an
original but all of which together shall constitute one and the same Agreement. This Agreement may also be executed and delivered by facsimile signature and in counterparts, each of which shall for all purposes be deemed to be an original but all of
which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced to evidence the existence of this Agreement. 

29. Captions. The headings of the paragraphs of this Agreement are inserted for convenience only and shall not be deemed to constitute
part of this Agreement or to affect the construction thereof.
