 1.2    
Request for Registration. 
 (a)     If the Company shall receive at any time after
the earlier of (i) the fourth anniversary of the date hereof, or (ii) six months after the effective date of the Qualified IPO, a written request from the Holders of at least sixty percent (60%) of the Registrable Securities then
outstanding (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of Registrable Securities with an anticipated aggregate offering price to the public of at
least $10,000,000, then the Company shall, within 20 days after receiving such request, give written notice of such request to all Holders and shall, subject to the limitations of subsection 1.2(b), use all commercially reasonable efforts to
cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered within 20 days after the mailing of such notice by the Company. 

(b)     If the Initiating Holders 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 and the Company shall include such information in the written notice referred to in subsection 1.2(a). The underwriter will be selected by the Company, which
underwriter shall be reasonably acceptable to the holders of at least sixty percent (60%) of the outstanding shares of the Registrable Securities that are to be included in the underwriting. In such event, the right of any Holder to include his
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 at
least 

  
 -3-

 
sixty percent (60%) of the outstanding shares held by the Initiating Holders and such Holder) to the extent provided herein. The Company and all Holders proposing to distribute their
securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected for such underwriting. Notwithstanding any other provision of this Section 1.2, if the underwriter
advises the Company in good faith that marketing factors require a limitation of the number of shares to be underwritten, then the Company 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 participating Holders thereof, including the Initiating Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities of the Company owned by each participating Holder. In no event shall any Registrable Securities be excluded from such underwriting unless all other securities are first excluded from such offering. Any Registrable Securities
excluded from or withdrawn from such underwriting shall be withdrawn from the registration. 
 (c)    
Notwithstanding the foregoing, if the Company shall furnish to the Initiating 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 seriously
detrimental to the Company and its stockholders for such registration statement to be filed, the Company shall have the right to defer such filing for a period of not more than 45 days after receipt of the request of the Initiating Holders;
provided, however, that the Company may not utilize this right or the similar right set forth in Section 1.4(b)(iii) more than twice in any 12-month period, and provided, further, that the Company shall not register any
securities for the account of itself or any other stockholder during each such 45-day period (other than in a Qualified IPO or an Excluded Registration). 
 (d)     In addition, the Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to this Section 1.2: 

(i)     After the Company has effected two (2) registrations pursuant to this Section 1.2(a), provided,
however, that such registrations have been declared or ordered effective and that either (A) the conditions of Section 1.5(a) have been satisfied, or (B) the registration statements remain effective and there are no stop orders in
effect to such registration statements; 
 (ii)     During the period starting with the date 90 days prior
to the Company’s good faith estimate of the date of filing of, and ending on a date 180 days after the effective date of, a registration subject to Section 1.3 hereof unless such offering is not the initial public offering of the
Company’s securities, in which case, ending on a date 90 days after the effective date of such registration subject to Section 1.3 hereof; provided that the Company is actively employing in good faith all commercially reasonable efforts to
cause such registration statement to become effective; or 
 (iii)     If the Initiating Holders propose to
dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 1.4 below. 

  
 -4-

  

1.3     Company Registration. 

(a)     If (but without any obligation to do so) the Company proposes to register (including for this purpose a
registration effected by the Company for stockholders other than the Holders) any of its stock under the Securities Act in connection with the public offering of such securities solely for cash (other than an Excluded Registration), the Company
shall, at such time, promptly give each Holder written notice of such registration. Upon the written request of each Holder given within 20 days after mailing of such notice by the Company in accordance with Section 3.5, the Company shall,
subject to the provisions of Section 1.8, use all commercially reasonable efforts to cause to be registered under the Securities Act all of the Registrable Securities that each such Holder has requested to be registered if any stock of the
Company is registered. 
 (b)     The Company shall have the right to terminate or withdraw any
registration initiated by it under this Section 1.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. The expenses of such registration shall be borne by the
Company, in accordance with Section 1.7 hereof. 
 1.4     Form S-3 Registration. In
case the Company shall receive from Holders of at least 10% of Registrable Securities then outstanding 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)     use all commercially reasonable efforts to effect, as soon as practicable, 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 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 1.4: (i) if Form S-3 is not 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 of less than $1,000,000; (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 seriously detrimental to the Company and its stockholders for such registration statement to be filed, the Company
shall have the right to defer such filing for a period of not more than 45 days after receipt of the request of the Holder or Holders under this Section 1.4; provided, however, that the Company shall not utilize this right or the
similar right set forth in Section 1.2(c) more than twice in any 12-month period; (iv) if the Company has, within the 12-month period preceding the date of such request, already effected two registrations

  
 -5-

 
on Form S-3 for the Holders pursuant to this Section 1.4; (v) in any jurisdiction in which the Company would be required to qualify to do business or to execute a general consent
to service of process in effecting such registration, qualification or compliance unless the Company is already qualified to do business or subject to service of process in that jurisdiction; or (vi) during the period ending 180 days after the
effective date of a registration statement subject to Section 1.3. 
 (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. Registrations effected
pursuant to this Section 1.4 shall not be counted as demands for registration or registrations effected pursuant to Sections 1.2 or 1.3, respectively. 
 1.5     Obligations of the Company. Whenever required under this Section 1 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 all commercially reasonable efforts to cause such registration statement to become effective, and, upon the request of the Holders of at least sixty percent (60%) of the Registrable Securities
registered thereunder, keep such registration statement effective for up to 120 days, or until the distribution described in such registration statement is completed, if earlier. 

(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 Securities Act with respect to the disposition of all securities covered by such registration statement for up to 120 days, or
until the distribution described in such registration statement is completed, if earlier. 
 (c)    
Promptly notify the Holders of the effectiveness of such registration statement, and furnish to the Holders such numbers of copies of a prospectus, including any supplement to the prospectus, in conformity with the requirements of the Securities
Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 
 (d)     Following the effective date of such registration statement, notify the Holders of any request by the SEC that the Company amend or supplement such registration statement, or
the associated prospectus. 
 (e)     Use all commercially reasonable 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 unless the Company is already qualified to do business or subject to service of process in that jurisdiction.

  
 -6-

  

(f)     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 and other security holder participating in such underwriting shall also enter into and perform its obligations under such an agreement.

 (g)     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 Securities 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, such obligation to continue for 120 days or until the
distribution described in such registration statement is completed, if earlier. 
 (h)     Cause all such
Registrable Securities registered pursuant to this Section 1 to be listed on each national securities exchange or trading system on which similar securities issued by the Company are then listed. 

(i)     Provide a transfer agent and registrar for all Registrable Securities registered pursuant hereunder and a
CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 

(j)     Make generally available to its security holders, and to deliver to each Holder participating in the
registration statement, an earnings statement of the Company that will satisfy the provisions of Section 11(a) of the Securities Act covering a period of 12 months beginning after the effective date of such registration statement as soon as
reasonably practicable after the termination of such 12-month period. 
 1.6     Information From
Holders. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this Section 1 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company
such information regarding such Holder, 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. The Company shall
have no obligation with respect to any registration requested pursuant to Section 1.2 or Section 1.4 of this Agreement if, as a result of the application of the preceding sentence, the anticipated aggregate offering price of the
Registrable Securities to be included in the registration does not equal or exceed the anticipated aggregate offering price required to originally trigger the Company’s obligation to initiate such registration as specified in subsection 1.2(a)
or subsection 1.4(b)(ii), whichever is applicable. 
 1.7     Expenses of Registration. All
expenses other than underwriting discounts and commissions incurred in connection with registrations, filings or qualifications pursuant to Sections 1.2, 1.3 and 1.4 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 selected by them with the approval of the Company, which approval shall not
be unreasonably 

  
 -7-

 
withheld, 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
Section 1.2 or 1.4 if the registration request is subsequently withdrawn at the request of the Holders of at least sixty percent (60%) of the Registrable Securities to be registered (in which case all participating Holders shall bear such
expenses), unless the Holders of at least sixty percent (60%) of the Registrable Securities agree to forfeit their right to one demand registration pursuant to Section 1.2 or one right to a Form S-3 registration under Section 1.4, as
the case may be; provided further, however, that if at the time of such withdrawal, the Holders (i) have learned of a material adverse change in the condition, business, or prospects of the Company that was not known to the
Holders at the time of their request and (ii) have withdrawn the request with reasonable promptness following disclosure by the Company of such material adverse change, then the Holders shall not be required to pay any of such expenses and
shall not forfeit their rights pursuant to Section 1.2 or Section 1.4, as the case may be. 

1.8     Underwriting Requirements. In connection with any offering involving an underwriting of shares
of the Company’s capital stock, the Company shall not be required under Section 1.3 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 the Company (or by other persons entitled to select the underwriters), and then only in such quantity as the underwriters determine in their sole discretion will not jeopardize the success of the offering by the Company.
If the total amount of securities, including Registrable Securities, requested by stockholders to be included in such offering exceeds the amount of securities sold other than by the Company that the underwriters determine in their sole discretion
is 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 determine in their sole discretion will not
jeopardize the success of the offering (the securities so included to be apportioned pro rata among the selling stockholders according to the total amount of securities entitled to be included therein owned by each selling stockholder or in such
other proportions as shall mutually be agreed to by such selling stockholders) but in no event shall the amount of securities of the selling Holders included in the offering be reduced below 30% of the total amount of securities included in such
offering, unless such offering is the initial public offering of the Company’s securities, in which case, the selling stockholders may be excluded if the underwriters make the determination described above and no other stockholder’s
securities are included. For purposes of the preceding parenthetical concerning apportionment, for any selling stockholder which is a holder of Registrable Securities and which is a venture capital fund, or a partnership or corporation, the
Affiliated Funds, partners, retired partners and stockholders 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 stockholder,” and any pro-rata reduction with respect to such “selling stockholder” shall be based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in
such “selling stockholder,” as defined in this sentence. Notwithstanding the foregoing, in no event shall any Registrable Securities be excluded from such offering unless all other stockholders’ securities have first been excluded.

 1.9     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 

  
 -8-

 
controversy that might arise with respect to the interpretation or implementation of this Section 1. 
 1.10     Indemnification. In the event any Registrable Securities are included in a registration statement under this Section 1: 

(a)     To the extent permitted by law, the Company will indemnify and hold harmless each Holder, any underwriter
(as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several)
to which they may become subject under the Securities Act, the Exchange 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 in such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (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 Securities Act, the Exchange Act, any state securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law; and the
Company will pay to each such Holder, underwriter or controlling person, as incurred, any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability, or action;
provided, however, that the indemnity agreement contained in this subsection 1.10(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 to any Holder, underwriter or controlling person 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 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 Securities 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 Securities Act, the Exchange 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 1.10(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 1.10(b) shall not apply to amounts paid in settlement of any such loss, claim, damage, 

  
 -9-

 
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 1.10(b) exceed the net proceeds from the offering received by such Holder, except in the case of willful fraud by such Holder. 
 (c)     Promptly after receipt by an indemnified party under this Section 1.10 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 1.10, 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 (together with all other indemnified parties which may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the reasonable 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 1.10, 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 1.10. 
 (d)     If the indemnification provided for in this Section 1.10 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; provided, that in no event shall any
contribution by a Holder under this Subsection 1.10(d) when combined with any amounts paid by such Holder pursuant to Subsection 1.10(b) exceed the net proceeds from the offering received by such Holder, except in the case of willful fraud by such
Holder. 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 or alleged 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.

 (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, the provisions in the underwriting agreement shall control. 

  
 -10-

  

(f)     The obligations of the Company and Holders under this Section 1.10 shall survive the completion of any
offering of Registrable Securities in a registration statement under this Section 1, and otherwise. 

1.11     Reports Under the Exchange Act. With a view to making available to the Holders the benefits
of Rule 144 promulgated under the Securities 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 90 days after the effective date of the Qualified IPO so long as the Company remains subject to the periodic reporting requirements under Sections 13 or 15(d) of the Exchange
Act; 
 (b)     take such action, including the voluntary registration of its Common Stock under
Section 12 of the Exchange 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 in which the first
registration statement filed by the Company for the offering of its securities to the general public is declared effective; 

(c)     file with the SEC in a timely manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act; and 
 (d)     furnish to any Holder upon request, so long as the
Holder owns any Registrable Securities, (i) a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after 90 days after the effective date of the Qualified IPO), the Securities
Act and the Exchange 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. 
 1.12    
Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 1 may be assigned (but only with all related obligations) by a Holder to a transferee or assignee
(i) of at least 100,000 shares of such securities (subject to adjustment for stock splits, stock dividends, reclassification or the like), (or if the transferring Holder owns less than 100,000 shares of such securities, then all Registrable
Securities held by the transferring Holder), (ii) that is a subsidiary, parent, partner, limited partner, retired partner, member, retired member or stockholder of a Holder, (iii) that is an Affiliated Fund, (iv) who is a
Holder’s child, stepchild, grandchild, parent, stepparent, grandparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law, or sister-in-law (such a relation, a Holder’s “Immediate Family
Member”, which term shall include adoptive relationships), or (v) that is a trust for the benefit of an individual Holder or such Holder’s Immediate Family Member, provided the Company is, within a reasonable time

  
 -11-

 
after such transfer, furnished with written notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned; and
provided, further , that such assignment shall be effective only if the transferee agrees in writing to be bound by this Agreement and immediately following such transfer the further disposition of such securities by the transferee or
assignee is restricted under the Securities Act. For the purposes of determining the number of shares of Registrable Securities held by a transferee or assignee, the holdings of transferees and assignees of (x) a partnership who are partners or
retired partners of such partnership or (y) a limited liability company who are members or retired members of such limited liability company (including Immediate Family Members of such partners or members who acquire Registrable Securities by
gift, will or intestate succession) shall be aggregated together and with the partnership or limited liability company; provided that all assignees and transferees who would not qualify individually for assignment of registration rights shall have a
single attorney-in-fact for the purpose of exercising any rights, receiving notices or taking any action under Section 1. 

1.13     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 at least sixty percent (60%) 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 include any of such securities in any registration filed under Section 1.2, Section 1.3 or Section 1.4 hereof, unless under the terms of such agreement, such holder or
prospective holder may include such securities in any such registration only to the extent that the inclusion of his securities will not reduce the amount of the Registrable Securities of the Holders which is included 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 1.2(a) or within 120 days of the effective date of any registration effected pursuant to
Section 1.2. 
 1.14     Lock-Up Agreement.  

(a)     Lock-Up Period; Agreement. In connection with the initial public offering of the
Company’s securities and upon request of the Company or the underwriters managing such offering of the Company’s securities, each Holder agrees not to sell, make any short sale of, loan, grant any option for the purchase of, or otherwise
dispose of any securities of the Company, however or whenever acquired (other than those included in the registration) without the prior written consent of the Company or such underwriters, as the case may be, for such period of time (not to exceed
180 days but subject to such extension or extensions as may be required by the underwriters in order to publish research reports while complying with the Rule 2711 of the National Association of Securities Dealers, Inc.) from the effective date of
such registration statement as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of the Company’s initial public offering.

 (b)     Limitations. The obligations described in Section 1.14(a) shall apply only if
all officers and directors of the Company and all greater than 1% stockholders enter into similar agreements, and shall not apply to a registration relating solely to employee benefit 

  
 -12-

 
plans, or to a registration relating solely to a transaction pursuant to Rule 145 under the Securities Act. 
 (c)     Stop-Transfer Instructions. In order to enforce the foregoing covenants, the Company may impose stop-transfer instructions with respect to the securities of each
Holder (and the securities of every other person subject to the restrictions in Section 1.14(a)). 

(d)     Transferees Bound. Each Holder agrees that prior to the Company’s initial public offering
it will not transfer securities of the Company unless each transferee agrees in writing to be bound by all of the provisions of this Section 1.14. 
 (e)     Legends. Each Holder agrees that a legend reading substantially as follows shall be placed on all certificates representing all Registrable Securities of each
Holder (and the shares or securities of every other person subject to the restriction contained in this Section 1.14): 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS AFTER THE EFFECTIVE DATE OF THE
ISSUER’S REGISTRATION STATEMENT FILED UNDER THE ACT, AS AMENDED, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SECURITIES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE. SUCH LOCK-UP
PERIOD IS BINDING ON TRANSFEREES OF THESE SHARES. 
 1.15     Termination of Registration
Rights. No Holder shall be entitled to exercise any right provided for in this Section 1 after the earlier of (i) with respect to any Holder, at such time after the Qualified IPO as Rule 144 or another similar exemption under
the Securities Act is available for the sale of all of such Holder’s shares during a three-month period without registration, or (ii) upon termination of the Agreement, as provided in Section 3.1. 

2.     Covenants of the Company. 

2.1     Delivery of Financial Statements. The Company shall deliver to each Major Investor:

 (a) as soon as practicable, but in any event within 180 days after the end of each fiscal year of the Company (or such
longer period of time as may be required by the Company’s independent public accountants), an income statement for such fiscal year, a balance sheet of the Company and statement of stockholder’s equity as of the end of such year, and a
statement of 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 audited and certified by a public accounting firm
selected by the Company and reasonably acceptable to the holders of Preferred Stock; 

  
 -13-

  
 (b) within 30 days of
the end of each month, an unaudited income statement and a statement of cash flows and balance sheet for and as of the end of such month, in reasonable detail; and 
 (c) as soon as practicable, but in any event prior to 30 days before the end of each fiscal year, a budget and business plan for the next fiscal year, prepared on a monthly basis, and, as soon as
prepared, any other updated or revised budgets for such fiscal year prepared by the Company. 
 2.2    
Inspection. The Company shall permit each Major Investor, at such Major Investor’s expense, to visit and inspect the Company’s properties, to examine its books of account and records and to discuss the Company’s affairs,
finances and accounts with its officers, all at such reasonable times as may be requested by the Major Investor; provided, however, that the Company shall not be obligated pursuant to this Section 2.2 to provide access to any
information which it reasonably considers to be a trade secret or similar confidential information. 

2.3     Right of First Offer. Subject to the terms and conditions specified in this Section 2.3,
the Company hereby grants to each Major Investor a right of first offer with respect to future sales by the Company of its Shares (as hereinafter defined). For purposes of this Section 2.3, Major Investor includes any general partners, managing
members and affiliates of a Major Investor, including Affiliated Funds. A Major Investor who chooses to exercise the right of first offer may designate as purchasers under such right itself or its partners or affiliates, including Affiliated Funds,
in such proportions as it deems appropriate. 
 Each time the Company proposes to offer any shares of, or securities
convertible into or exercisable for any shares of, any class of its capital stock (“Shares”), the Company shall first make an offering of such Shares to each Major Investor in accordance with the following provisions: 

(a)     The Company shall deliver a notice (the “RFO Notice”) to the Major Investors stating
(i) its bona fide intention to offer such Shares, (ii) the number of such Shares to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such Shares. 

(b)     Within 15 days after delivery of the RFO Notice, the Major Investor may elect to purchase or obtain, at the
price and on the terms specified in the RFO Notice, up to that portion of such Shares which equals the proportion that the number of shares of Registrable Securities issued and held, or issuable upon conversion and exercise of all convertible or
exercisable securities then held, by such Major Investor on an as-converted basis bears to the sum of (A) the total number of shares of Common Stock then outstanding (assuming full conversion and exercise of all convertible or exercisable
securities) and (B) shares of Common Stock issuable to employees, consultants or directors pursuant to a stock option plan, restricted stock plan, or other stock plan approved by the Board of Directors. Such purchase shall be completed at the
same closing as that of any third party purchasers or at an additional closing. The Company shall promptly, in writing, inform each Major Investor that purchases all the shares available to it (each, a “Fully-Exercising Investor”)
of any other Major Investor’s 

  
 -14-

 
failure to do likewise. During the 10-day period commencing after receipt of such information, each Fully-Exercising Investor shall be entitled to obtain that portion of the Shares for which
Major Investors were entitled to subscribe but which were not subscribed for by the Major Investors that is equal to the proportion that the number of shares of Common Stock issued and held, or issuable upon conversion and exercise of all
convertible or exercisable securities then held, by such Fully-Exercising Investor bears to the total number of shares of Common Stock held by all Fully-Exercising Investors (assuming full conversion and exercise of all convertible or exercisable
securities). 
 (c)     The Company may, during the 45-day period following the expiration of the period
provided in subsection 2.3(b) hereof, offer the remaining unsubscribed portion of the Shares to any person or persons at a price not less than, and upon terms no more favorable to the offeree than those specified in the RFO Notice. If the
Company does not enter into an agreement for the sale of the Shares within such period, or if such agreement is not consummated within 60 days after the execution thereof, the right provided hereunder shall be deemed to be revived and such Shares
shall not be offered unless first reoffered to the Major Investors in accordance herewith. 
 (d)     The
right of first offer in this Section 2.3 shall not be applicable to 
 (i) the issuance of securities in connection
with stock dividends, stock splits or similar transactions; 
 (ii) the issuance of Common Stock, issued to or issuable to
employees, consultants and directors of the Company, pursuant to any stock option plan or agreement or other stock incentive program or agreement of the Company approved by the Board of Directors of the Company, including at least two of the
Preferred Director Representatives then in office; 
 (iii) the issuance of securities to financial institutions, equipment
lessors, brokers or similar persons in connection with commercial credit arrangements, equipment financings, commercial property lease transactions or similar transactions, provided such issuances are for other than primarily equity financing
purposes and provided further that the terms of which are approved by the Board of Directors of the Company, including at least two of the Preferred Director Representatives then in office; 

(iv) the issuance of securities pursuant to the conversion or exercise of convertible or exercisable securities outstanding as of the
date of this Agreement, including without limitation, warrants, notes or options; 
 (v) the issuance of the Common Stock
issuable upon conversion of the Preferred Stock; 
 (vi) the issuance of Common Stock in a Qualified IPO; 

(viii) the issuance of securities to an entity as a component of any business relationship with such entity primarily for the purpose of
(A) joint venture, technology 

  
 -15-

 
licensing or development activities, (B) distribution, supply or manufacture of the Company’s products or services, or (C) merger or asset purchase with such entity, provided that
the terms of such business relationship with such entity are approved by the Board of Directors including the approval of at least two of the Preferred Director Representatives then in office; or 

(ix) the issuance of securities that, with unanimous approval of the Company’s Board of Directors, are not offered to any existing
stockholder of the Company. 
 In addition to the foregoing, the right of first offer in this Section 2.3 shall not be
applicable with respect to any Major Investor and any subsequent securities issuance, if (i) at the time of such subsequent securities issuance, the Major Investor is not an “accredited investor,” as that term is then defined in Rule
501(a) under the Securities Act, and (ii) such subsequent securities issuance is otherwise being offered only to accredited investors. 
 2.4     Qualified Small Business Stock Status. In the event that the Company proposes to take an action or engage in a transaction that would reasonably be expected to
result in the Shares no longer being “qualified small business stock” within the meaning of Section 1202(c) of the Internal Revenue Code of 1986, as amended (the “Code”), the Company shall notify the Major Investors
and consult in good faith to devise a mutually agreeable and reasonable alternative course of action or transaction structure that would preserve such status. In addition, the Company shall submit to the Major Investors and to the Internal Revenue
Service any reports that may be required under Section 1202(d)(1)(C) of the Code and any related Treasury Regulations. In addition, within ten (10) days after any Major Investor has delivered to the Company a written request therefor, the
Company shall deliver to such Major Investor a written statement informing the Major Investor whether, in the Company’s good-faith judgment after a reasonable investigation, such Major Investor’s interest in the Company constitutes
“qualified small business stock” as defined in Section 1202(c) of the Code, or would constitute “qualified small business stock,” if determination of whether stock constitutes “qualified small business stock” were
made by taking into account the modifications set forth in Section 1045(b)(4) of the Code. The Company’s obligation to furnish a written statement pursuant to this Section 2.4 shall continue notwithstanding the fact that a class of
the Company’s stock may be traded on an established securities market. 
 2.5     Stock
Vesting. Unless otherwise approved by the Board of Directors, including at least two of the Preferred Director Representatives then in office, all stock options and other stock equivalents issued after the date of this Agreement to
employees, directors, consultants and service providers shall be subject to vesting as follows: (a) twenty-five percent (25%) of such stock shall vest at the end of the first year following the earlier of the date of issuance or, solely in
the case of an initial grant upon commencement of services, such person’s services commencement date with the Company, and (b) seventy-five percent (75%) of such stock shall vest in equal monthly installments over the remaining three
(3) years. The Company shall retain a right of first refusal on transfers of Common Stock until the Company’s initial public offering and the right to repurchase unvested shares at cost. 

2.6     Reservation of Next Round Stock. The Company will at all times reserve and keep available,
solely for issuance and delivery upon conversion of the Series C Preferred 

  
 -16-

 
Stock of the Company, all Next Round Stock (as defined in the Restated Charter) issuable from time to time upon such conversion. 

2.7     Termination of Covenants. 

(a)     The covenants set forth in Sections 2.1 through Section 2.6 shall terminate as to each Holder and be of
no further force or effect (i) immediately prior to the consummation of a Qualified IPO, or (ii) upon termination of the Agreement, as provided in Section 3.1. 
 (b)     The covenants set forth in Sections 2.1 and 2.2 shall terminate as to each Holder and be of no further force or effect when the Company first becomes subject to the
periodic reporting requirements of Sections 13 or 15(d) of the Exchange Act, if this occurs earlier than the events described in Section 2.7(a) above. 
 3.     Miscellaneous. 

3.1     Termination. This Agreement shall terminate, and have no further force and effect, when the
Company shall consummate a transaction or series of related transactions deemed to be a Liquidation Transaction pursuant to the Restated Charter. 
 3.2     Entire Agreement. This Agreement constitutes the entire agreement between the parties hereto pertaining to the subject matter hereof, and any and all other
written or oral agreements relating to the subject matter hereof existing between the parties hereto are expressly canceled. This Agreement amends and restates the Prior Agreement in its entirety and upon the effectiveness of this Agreement, the
Prior Agreement shall be of no further force or effect. 
 3.3     Successors and Assigns.
Except as otherwise provided in this Agreement, the terms and conditions of this Agreement shall inure to the benefit of and be binding upon the respective permitted successors and assigns of the parties (including transferees of any of the
Preferred Stock or any Common Stock issued upon conversion thereof). Nothing in this Agreement, express or implied, is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

3.4     Amendments and Waivers. Any term of this Agreement may be amended or waived only with the
written consent of the Company and the holders of at least sixty percent (60%) of the Registrable Securities then outstanding; provided, however, that if such amendment or waiver would adversely affect the rights of a specific
series of Preferred Stock in a manner different from the other series of Preferred Stock, then such amendment or waiver shall require the consent of the holders of at least sixty percent (60%) of the outstanding shares of such series of
Preferred Stock; and any amendment or waiver of the rights granted to the Major Investors in Section 2 above shall require the consent of the Major Investors holding at least sixty percent (60%) of the outstanding shares of Registrable
Securities then held by the Major Investors. Notwithstanding the foregoing, this Agreement may be amended with only the written consent of the Company for the sole purpose of including additional purchasers of Series

  
 -17-

 
C Preferred Stock as “Investors” and “Holders.” Any amendment or waiver effected in accordance with this paragraph shall be binding upon each party to the Agreement, whether
or not such party has signed such amendment or waiver, each future holder of all such Registrable Securities, and the Company. 

3.5     Waiver of Right of First Offer. Each Major Investor, on behalf of itself and all other
Major Investors, hereby waives the right of first offer contained in Section 2.3 of the Prior Agreement, including all notice provisions contained therein, with respect to the transactions contemplated by the Purchase Agreement, including the
sale of the Series C Preferred Stock pursuant to the terms thereof. 
 3.6    
Notices. Unless otherwise provided, any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient upon delivery, when delivered personally or by overnight courier or sent by facsimile, or 48
hours after being deposited in the U.S. mail, as certified or registered mail, with postage prepaid, and addressed (a) if to an Investor, at the Investor’s address or facsimile number as set forth on Exhibit A hereto, or as
subsequently modified by written notice, with a copy to Gunderson Dettmer Stough Villeneuve Franklin & Hachigian, LLP, 1200 Seaport Blvd, Redwood City, CA 94063, Attn: Marcia Hatch, (b) if to a Series B Holder, at the Series B
Holder’s address or facsimile number as set forth on Exhibit B hereto, (c) if to a Series A Holder, at the Series A Holder’s address or facsimile number as set forth on Exhibit C hereto and (d) if to the Company, at
575 Chesapeake Drive, Redwood City, CA 94063 or fax number (650) 216-6500, or as subsequently modified by written notice, with a copy to Cooley Godward Kronish LLP, 5 Palo Alto Square, 3000 El Camino Real, Palo Alto, CA 94306,
Attn: Mark Weeks. 
 3.7     Severability. If one or more provisions of this Agreement
are held to be unenforceable under applicable law, such provision shall be excluded from this Agreement, and the balance of the Agreement shall be interpreted as if such provision were so excluded and shall be enforceable in accordance with its
terms. 
 3.8     Governing Law. This Agreement and all acts and transactions pursuant hereto
shall be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles of conflicts of laws. 
 3.9     Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute
one and the same instrument. 
 3.10     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. 

3.11     Aggregation of Stock. All shares of the Preferred Stock held or acquired by affiliated
entities or persons, including Affiliated Funds, shall be aggregated together for the purpose of determining the availability of any rights under this Agreement.
