after the date of this Agreement or (ii) six (6) months after the effective date of the Initial Offering or, if earlier, a Direct Listing, a written request from the 

  
 3 

 
Holders of fifty percent (50%) or more of the Registrable Securities then outstanding (for purposes of this Section 1.2, the “Initiating Holders”) that the Company file a
registration statement under the Act covering the registration of Registrable Securities with an anticipated aggregate offering price of at least $15,000,000, then the Company shall, within twenty (20) days of the receipt thereof, give written
notice of such request to all Holders, and subject to the limitations of this Section 1.2, use all commercially reasonable efforts to effect, as soon as practicable, the registration under the Act of all Registrable Securities that the Holders
request to be registered in a written request received by the Company within twenty (20) days of the mailing of the Company’s notice pursuant to this Section 1.2(a). 

(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 made pursuant to this Section 1.2, and the Company shall include such information in the written notice referred to in Section 1.2(a). In such event the right of any Holder to include
its 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 and such Holder) to the extent provided herein. 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 by the Company (which underwriter or underwriters shall be reasonably acceptable to those Initiating Holders holding a majority of the Registrable Securities held by all Initiating Holders).
Notwithstanding any other provision of this Section 1.2, if the underwriter advises the Company that marketing factors require a limitation on the number of securities underwritten (including Registrable Securities), then the Company shall so
advise all Holders of Registrable Securities that would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated to the Holders of such Registrable Securities pro rata based on
the number of Registrable Securities held by all such Holders (including the Initiating Holders). In no event shall any Registrable Securities be excluded from such underwriting unless all other securities are first excluded. Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration. 
 (c) Notwithstanding the foregoing, the
Company shall not be required to effect a registration pursuant to this Section 1.2: 
 (i) in any particular jurisdiction in which
the Company would be required to execute a general consent to service of process in effecting such registration, unless the Company is already subject to service in such jurisdiction and except as may be required under the Act; or 

(ii) after the Company has effected one (1) registration pursuant to this Section 1.2, and such registration has been declared or
ordered effective; or 
 (iii) during the period starting with the date sixty (60) days prior to the Company’s good faith
estimate of the date of the filing of and ending on a date one hundred eighty (180) days following the effective date of a Company-initiated registration subject to Section 1.3 below, provided
that the Company is actively employing in good faith all commercially reasonable efforts to cause such registration statement to become effective; or 

  
 4 

 (iv) if the Initiating Holders propose to dispose of Registrable Securities that may be
registered on Form S-3 pursuant to Section 1.4 hereof; or 
 (v) if the Company shall
furnish to Holders requesting a registration statement pursuant to this Section 1.2 a certificate signed by the Company’s Chief Executive Officer or Chairman of the Board of Directors 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 effected at such time, in which event 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, provided that such right shall be exercised by the Company not more than once in any twelve (12) month period and provided further that
the Company shall not register any securities for the account of itself or any other stockholder during such ninety (90) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a
registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement
covering the sale of the Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered). 

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 or other securities under the Act in connection with the public offering of such securities (other than (i) a Direct Listing, (ii) a registration relating to a demand
pursuant to Section 1.2, or (iii) a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating to a corporate reorganization or transaction under Rule 145 of the Act, a
registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the Registrable Securities, or a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities that are also being registered), the Company shall, at such time, 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 3.5, the Company shall, subject to the provisions of Section 1.3(c), use all commercially reasonable efforts to cause to be registered
under the Act all of the Registrable Securities that each such Holder requests to be registered. 
 (b) Right to Terminate
Registration. 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 withdrawn registration shall be borne by the Company in accordance with Section 1.7 hereof. 

(c) 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 this Section 1.3 to include any of the Holders’ securities in such underwriting unless they accept the terms of 

  
 5 

 
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 enter into an underwriting agreement
in customary form with such 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, that the underwriters determine in their sole discretion will not jeopardize the success of the offering. In no event shall
any Registrable Securities be excluded from such offering unless all other stockholders’ securities have been first excluded. In the event that the underwriters determine that less than all of the Registrable Securities requested to be
registered can be included in such offering, then the Registrable Securities that are included in such offering shall be apportioned pro rata among the selling Holders based on the number of Registrable Securities held by all selling Holders or in
such other proportions as shall mutually be agreed to by all such selling Holders. Notwithstanding the foregoing, in no event shall (i) the amount of securities of the selling Holders included in the offering be reduced below thirty percent
(30%) of the total amount of securities included in such offering, unless such offering is the Initial Offering, in which case the selling Holders may be excluded if the underwriters make the determination described above and no other
stockholder’s securities are included in such offering or (ii) any securities held by a Common Holder be included in such offering if any Registrable Securities held by any Holder other than a Common Holder (and that such Holder has
requested to be registered) are excluded from such offering. For purposes of the preceding sentence concerning apportionment, for any selling stockholder that is a Holder of Registrable Securities and that is a venture capital or other investment
fund, partnership or corporation, the Affiliates of such venture capital or other investment funds, partners, retired partners, members and stockholders of such Holder, or the estates and family members of any such partners, members and retired
partners and any trusts for the benefit of any of the foregoing persons shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate amount of
Registrable Securities owned by all such related entities and individuals. 
 1.4 Form S-3
Registration. In case the Company shall receive from the Holders of at least thirty percent (30%) of the Registrable Securities (for purposes of this Section 1.4, the “S-3 Initiating
Holders”) 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 shall: 
 (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 Holders’ Registrable Securities as are specified in such request,
together with all or such portion of the Registrable Securities of any other 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 1.4: 

  
 6 

 (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 (net of any underwriters’ discounts or commissions) of less than $10,000,000; 

(iii) if the Company shall furnish to all Holders requesting a registration statement pursuant to this Section 1.4 a certificate signed
by the Company’s Chief Executive Officer or Chairman of the Board of Directors 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 effected at such time, in which event 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
S-3 Initiating Holders, provided that such right shall be exercised by the Company not more than once in any twelve (12) month period and provided further that the Company shall not
register any securities for the account of itself or any other stockholder during such ninety (90) day period (other than a registration relating solely to the sale of securities of participants in a Company stock plan, a registration relating
to a corporate reorganization or transaction under Rule 145 of the Act, a registration on any form that does not include substantially the same information as would be required to be included in a registration statement covering the sale of the
Registrable Securities, or a registration in which the only Common Stock being registered is Common Stock issuable upon conversion of debt securities that are also being registered); 

(iv) if the Company has, within the twelve (12) month period preceding the date of such request, already effected two
(2) registrations on Form S-3 pursuant to this Section 1.4; 
 (v) in any particular
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; or 

(vi) if the Company, within thirty (30) days of receipt of the request of such S-3 Initiating
Holders, gives notice of its bona fide intention to effect the filing of a registration statement with the SEC within one hundred twenty (120) days of receipt of such request (other than a registration effected solely to qualify an employee
benefit plan or to effect a business combination pursuant to Rule 145), provided that the Company is actively employing in good faith all commercially reasonable efforts to cause such registration statement to become effective; or 

(vii) during the period starting with the date thirty (30) days prior to the Company’s good faith estimate of the date of the
filing of and ending on a date ninety (90) days following the effective date of a Company-initiated registration subject to Section 1.3 above, provided that the Company is actively employing
in good faith all commercially reasonable efforts to cause such registration statement to become effective. 

  
 7 

 (c) If the S-3 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 made pursuant to this Section 1.4 and the Company shall include such information in the
written notice referred to in Section 1.4(a). The provisions of Section 1.2(b) shall be applicable to such request (with the substitution of Section 1.4 for references to Section 1.2). 

(d) 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 S-3 Initiating Holders. Registrations effected pursuant to this Section 1.4 shall not be counted as
requests for registration effected pursuant to Section 1.2. 
 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 a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to one
hundred twenty (120) days or, if earlier, until the distribution contemplated in the Registration Statement has been completed; 
 (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 number of copies of a prospectus,
including a preliminary prospectus and any Free Writing 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 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; 
 (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; 

  
 8 

 (f) notify each Holder of Registrable Securities covered by such registration statement at
any time when a prospectus or Free Writing Prospectus (to the extent prepared by or on behalf of the Company) 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, and, at the request of any such Holder, the Company will, as soon as reasonably practicable, file and furnish to all such Holders a supplement or amendment to such prospectus or Free Writing Prospectus (to the extent
prepared by or on behalf of the Company) so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus will not contain an untrue statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading in light of the circumstances under which they were made; 
 (g) promptly make available for inspection
by the selling Holders, any underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and
other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees, and independent accountants to supply all information reasonably requested by any such seller, underwriter,
attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 

(h) cause all such Registrable Securities registered pursuant to this Section 1 to be listed on a national exchange or trading system
and on each securities exchange and trading system on which similar securities issued by the Company are then listed; and 
 (i) provide a
transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and a CUSIP number for all such Registrable Securities, in each case not later than the effective date of such registration. 

Notwithstanding the provisions of this Section 1, the Company shall be entitled to postpone or suspend, for a reasonable period of time,
the filing, effectiveness or use of, or trading under, any registration statement if the Company shall determine that any such filing or the sale of any securities pursuant to such registration statement would in the good faith judgment of the Board
of Directors of the Company: 
 (i) materially impede, delay or interfere with any material pending or proposed financing, acquisition,
corporate reorganization or other similar transaction involving the Company for which the Board of Directors of the Company has authorized negotiations; 

(ii) materially adversely impair the consummation of any pending or proposed material offering or sale of any class of securities by the
Company; or 

  
 9 

 (iii) require disclosure of material nonpublic information that, if disclosed at such time,
would be materially harmful to the interests of the Company and its stockholders; provided, however, that during any such period all executive officers and directors of the Company are also prohibited from selling securities of the
Company (or any security of any of the Company’s subsidiaries or its Affiliates). 
 In the event of the suspension of effectiveness of
any registration statement pursuant to this Section 1.5, the applicable time period during which such registration statement is to remain effective shall be extended by that number of days equal to the number of days the effectiveness of such
registration statement was suspended. 
 1.6 Information from Holder. 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 itself, the Registrable Securities held by it, and
the intended method of disposition of such securities as shall be reasonably required to effect the registration of such Holder’s Registrable Securities. 

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 (not to exceed $50,000) shall be borne by the Company. Notwithstanding the foregoing, the Company shall not be required to pay for any expenses of any registration proceeding
begun pursuant to Section 1.2 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 pro
rata based upon the number of Registrable Securities that were to be included in the withdrawn registration), unless, in the case of a registration requested under Section 1.2 or Section 1.4, the Holders of a majority of the Registrable
Securities agree to forfeit their right to one demand registration pursuant to Section 1.2 and provided, however, that if at the time of such withdrawal, the Holders have learned of a material adverse change in the condition,
business or prospects of the Company from that known to the Holders at the time of their request and 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 retain their rights pursuant to Section 1.2 and Section 1.4. 
 1.8
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 1. 
 1.9 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, the partners, members, officers, directors and stockholders of each Holder, legal counsel and accountants for each Holder, any underwriter (as defined in the Act) if any, or, in the case 

  
 10 

 
of a Direct Listing, any financial advisor retained by the Company to assist in effecting such Direct Listing ,for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Act or 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, any state securities laws or any rule or regulation promulgated under
the Act, the 1934 Act or any state securities laws, 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, final prospectus, or Free Writing Prospectus contained
therein or any amendments or supplements thereto, 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 such registration prepared by or on
behalf of the Company or used or referred to by the Company, (ii) the omission or alleged omission to state in such registration statement 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 laws or any rule or regulation promulgated under the Act, the 1934 Act or any state securities laws, and the Company will reimburse each
such Holder, underwriter, controlling person or other aforementioned person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action as such expenses
are incurred; provided, however, that the indemnity agreement contained in this subsection l.9(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 that occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by any such Holder, underwriter, controlling person or other aforementioned person. 

(b) To the extent permitted by law, each selling Holder, severally and not jointly, 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, legal counsel and accountants for the Company, 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, any state securities laws or any rule or regulation promulgated under the Act, the 1934 Act or any state securities laws, insofar as such losses, claims, damages or liabilities (or actions, whether commenced or threatened, 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 reimburse any person intended to be indemnified pursuant to this subsection l.9(b) for any legal or other expenses reasonably incurred by such person in connection with investigating or
defending any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the indemnity agreement contained in this subsection l.9(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), and provided that in no event shall any indemnity under this
subsection l.9(b) exceed the net proceeds from the offering received by such Holder. 

  
 11 

 (c) Promptly after receipt by an indemnified party under this Section 1.9 of notice of
the commencement of any action (including any governmental action) for which a party may be entitled to indemnification, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this
Section 1.9, 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 that may be represented
without conflict by one counsel) shall have the right to retain one (1) separate 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 liability to the indemnified party under this Section 1.9 to the extent of such prejudice, but
the omission to so 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 1.9. 

(d) If the indemnification provided for in this Section 1.9 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 herein, 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 the indemnified party on the other hand 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, however, that (i) no contribution by any Holder, when combined
with any amounts paid by such Holder pursuant to Section 1.9(b), shall exceed the net proceeds from the offering received by such Holder and (ii) no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Act) will be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Section 1.9(d), when
combined with the amounts paid or payable by such Holder pursuant to Section 1.9(b), exceed the proceeds from the offering received by such Holder (net of any expenses paid by such Holder). The relative fault of the indemnifying party and 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. 

  
 12 

 (f) The obligations of the Company and Holders under this Section 1.9 shall survive
the completion of any offering of Registrable Securities in a registration statement under this Section 1, termination of any provision(s) of this Agreement, and otherwise. 

1.10 Reports Under the 1934 Act. With a view to making available to the Holders the benefits of Rule 144 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 Rule 144, at all times after the effective
date of the Initial Offering or Direct Listing; 
 (b) 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 
 (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith
upon request (i) a written statement by the Company that it has complied with the reporting requirements of 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 to avail
any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration or pursuant to such form. 

1.11 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 of such securities that (a) is an Affiliate, subsidiary, parent, partner, member, limited partner, retired partner or stockholder of
a Holder, or (b) is a Holder’s family member or trust for the benefit of an individual Holder, provided: (i) the Company is, within a reasonable time 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; (ii) such transferee or assignee agrees in writing to be bound by and subject to the terms and conditions of this Agreement,
including, without limitation, the provisions of Section 1.13 below; and (iii) such assignment shall be effective only if immediately following such transfer the further disposition of such securities by the transferee or assignee is
restricted under the Act. 
 1.12 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 holding a majority of the Registrable Securities then held by all Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that would
allow such holder or prospective holder (a) to include any of such securities in any 

  
 13 

 
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 such securities will not reduce the amount of the Registrable Securities of the Holders that are included or (b) to demand registration of their securities. 

1.13 “Market Stand-Off” Agreement. 

(a) Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing
on the date of the final prospectus relating to the Initial Offering and ending on the date specified by the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days) (i) lend, offer, pledge, sell,
contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any
securities convertible into or exercisable or exchangeable for Common Stock owned or controlled by such Holder immediately prior to the effectiveness of the Registration Statement for such offering or (ii) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Stock
or other securities, in cash or otherwise. The foregoing provisions of this Section 1.13 shall apply only to the Initial Offering, shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, and shall only
be applicable to the Holders if all officers, directors and greater than one percent (1%) stockholders of the Company enter into similar agreements. The underwriters in connection with the Initial Offering are intended
third-party beneficiaries of this Section 1.13 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such
agreements as may be reasonably requested by the underwriters in the Initial Offering that are consistent with this Section 1.13 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the restrictions
of any or all of such agreements by the Company or the underwriters shall apply to all Holders subject to such agreements pro rata based on the number of shares subject to such agreements. 

In order to enforce the foregoing covenant, the Company may impose stop-transfer instructions with
respect to the Registrable Securities of each Holder (and the shares or securities of every other person subject to the foregoing restriction) until the end of such period. 

(b) 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 1.13): 

THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD 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. 

  
 14 

 1.14 Termination of Registration Rights. No Holder shall be entitled to exercise any
right provided for in this Section 1 (a) after five (5) years following the consummation of the Qualified Public Offering (as defined in the Restated Certificate), (b) as to any Holder, such earlier time after the Initial Offering at which
such Holder (i) can sell all shares held by it in compliance with Rule 144(b)(1)(i) or (ii) holds one percent (1%) or less of the Company’s outstanding Common Stock and all Registrable Securities held by such Holder (together
with any Affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can be sold in any three (3) month period without registration in compliance with Rule 144 or (c) after the consummation of a
Liquidation Event pursuant to which the Investors receive cash and/or marketable securities. 
 2. Covenants of the Company. 

2.1 Delivery of Financial Statements. The Company shall, upon request, deliver to each Investor (or transferee of an Investor) that
holds at least 3,606,168 shares of Common Stock (assuming full conversion, exchange and exercise of all Company securities held by such Investor that are convertible, exchangeable or exercisable into shares of Common Stock, and appropriately
adjusted for any stock split, dividend, combination or other recapitalization) (a “Major Investor”); provided, however, that any entity that (i) is formed for the specific purpose of acquiring shares of the Company’s
capital stock and/or (ii) has assets, a majority of which consist of shares of the Company’s capital stock as of immediately following such entity’s acquisition of shares of the Company’s capital stock (each, an “SPV
Entity”), shall not constitute an Affiliate of such Investor for the purpose of qualifying as a Major Investor: 
 (a) as soon as
practicable, but in any event within one hundred twenty (120) days after the end of each fiscal year of the Company, an income statement for such fiscal year, a balance sheet of the Company and a statement of stockholders’ equity as of the
end of such year, and an 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 independent public accountants of nationally recognized standing selected by the Company; provided, however, the financial statements may be unaudited for any year with the
approval of the Board of Directors (including a least one of the Preferred Directors); 
 (b) as soon as practicable, but in any event
within forty-five (45) days after the end of each of the first three (3) quarters of each fiscal year of the Company, an unaudited income statement, statement of cash flows for such fiscal quarter and an unaudited balance sheet as of the
end of such fiscal quarter, all prepared in accordance with GAAP (except that such financial statements may (i) be subject to normal year-end audit adjustments and (ii) not contain all notes thereto
that may be required in accordance with GAAP); 
 (c) within thirty (30) days of the end of each month, an unaudited income statement
and statement of cash flows for such month, and an unaudited balance sheet as of the end of such month, all prepared in accordance with GAAP (except that such financial statements may (i) be subject to normal
year-end audit adjustments and (ii) not contain all notes thereto that may be required in accordance with GAAP); 

  
 15 

 (d) as soon as practicable, but in any event at least sixty (60) days prior to the end
of each fiscal year, a budget and business plan for the next fiscal year, approved by the Board of Directors (including at least one of the Preferred Directors) and prepared on a monthly basis, including balance sheets, income statements and
statements of cash flows for such months and, as soon as prepared, any other budgets or revised budgets prepared by the Company; 
 (e)
such other information relating to the financial condition, business or corporate affairs of the Company, as well as detailed capitalization information, as the Major Investor may from time to time request, provided, however, that the
Company shall not be obligated under this subsection (f) or any other subsection of Section 2.1 to provide information that (i) it deems in good faith to be a trade secret or similar confidential information or (ii) the
disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel; 
 If, for any period, the
Company has any subsidiary whose accounts are consolidated with those of the Company, then in respect of such period the financial statements delivered pursuant to the foregoing sections shall be the consolidated and consolidating financial
statements of the Company and all such consolidated subsidiaries. Notwithstanding anything else in this Section 2.1 to the contrary, the Company may cease providing the information set forth in this Section 2.1 during the period starting
with the date thirty (30) days before the Company’s good-faith estimate of the date of filing of a registration statement if it reasonably concludes it must do so to comply with the SEC rules applicable to such registration statement and
related offering; provided that the Company’s covenants under this Section 2.1 shall be reinstated at such time as the Company is no longer actively employing its commercially reasonable efforts to cause such registration statement
to become effective. 
 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 that it reasonably considers to be a trade secret or similar confidential information. 

2.3 Termination of Information and Inspection Covenants. The covenants set forth in Sections 2.1 and 2.2 shall terminate and be of
no further force or effect upon the earlier to occur of (a) the consummation of the Initial Offering or Direct Listing, (b) when the Company first becomes subject to the periodic reporting requirements of Sections 12(g) or 15(d) of
the 1934 Act, whichever event shall first occur or (c) the consummation of a Liquidation Event pursuant to which the Investors receive cash and/or marketable securities. 

2.4 Right of First Offer. Subject to the terms and conditions specified in this Section 2.4, 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 2.4, the term “Major Investor” includes any general partners and Affiliates
of a Major Investor. A Major Investor shall be entitled to apportion the right of first offer hereby granted it among itself and its partners and Affiliates in such proportions as it deems appropriate. 

  
 16 

 Each time the Company proposes to offer any shares of, or securities convertible into or
exchangeable or exercisable for any shares 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 in accordance with Section 3.5 (“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 upon which it proposes to offer such Shares. 

(b) By written notification received by the Company within twenty (20) calendar days after the giving of Notice, each Major Investor may
elect to purchase, at the price and on the terms specified in the Notice, up to that portion of such Shares (the “Pro Rata Share”) that equals the proportion of all Common Stock issued and held by such Major Investor (assuming full
conversion, exchange and exercise of all Company securities held by such Major Investor that are convertible, exchangeable or exercisable into shares of Common Stock) bears to the total number of shares of Common Stock of the Company then
outstanding (assuming full conversion, exchange and exercise of all Company securities then outstanding that are convertible, exchangeable or exercisable into shares of Common Stock). The Company shall promptly, in writing, inform each Major
Investor that elects to purchase all the shares available to it (a “Fully-Exercising Investor”) of any other Major Investor’s failure to do likewise. During the ten (10) day period commencing after such information is
given, each Fully-Exercising Investor may elect to purchase 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 by such Fully-Exercising Investor (assuming full conversion, exchange and exercise of all Company securities held by such
Fully-Exercising Investor that are convertible, exchangeable or exercisable into shares of Common Stock) bears to the total number of shares of Common Stock issued and held by all Fully-Exercising Investors
who wish to purchase some of the unsubscribed shares (assuming full conversion, exchange and exercise of all Company securities held by all such Fully-Exercising Investors that are convertible, exchangeable or exercisable into shares of Common
Stock). 
 (c) If all Shares that Major Investors are entitled to obtain pursuant to subsection 2.4(b) are not elected to be obtained
as provided in subsection 2.4(b) hereof, the Company may, during the ninety (90) day period following the expiration of the period provided in subsection 2.4(b) hereof, offer the remaining unsubscribed portion of such Shares to any
person or persons at a price not less than that, and upon terms no more favorable to the offeree than those, specified in the 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 sixty (60) days of 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 2.4 shall not be applicable to (i) issuances of Carve Out Stock (as defined in the
Restated Certificate) or (ii) the issuance and sale of Series F Preferred Stock pursuant to the Series F Agreement. In addition to the foregoing, the right of first offer in this Section 2.4 shall not be applicable with respect to any
Major Investor in any subsequent offering of Shares if (i) at the time of such offering, the Major Investor is not an “accredited investor,” as that term is then defined in Rule 501(a) of the Act and (ii) such offering of Shares
is otherwise being offered only to accredited investors. 

  
 17 

 (e) The rights provided in this Section 2.4 may not be assigned or transferred by any
Major Investor; provided, however, that a Major Investor that is a venture capital fund may assign or transfer such rights to its Affiliates that are not SPV Entities. 

2.5 Observer Rights. 

(a) As long as Institutional Venture Partners XV Executive Fund, L.P. and Institutional Venture Partners XV, L.P. (collectively with their
Affiliates, “IVP”) own not less than 664,496 shares of the Series C Preferred Stock it purchased under the Series C Stock Purchase Agreement dated on or around June 16, 2017 (or an equivalent amount of Common Stock issued upon
conversion thereof) (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification effected after the date hereof), the Company shall invite a representative of IVP to attend all meetings of its Board of
Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its directors at the same time and in the same manner as provided to
such directors; provided, however, that such representative shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information so provided; and provided further, that the Company reserves the right to
withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or
result in disclosure of trade secrets or a conflict of interest. 
 (b) As long as Jasmine Ventures Pte. Ltd (“GIC”) owns
not less than 314,143 shares of the Series E Preferred Stock (or an equivalent amount of Common Stock issued upon conversion thereof) (as adjusted for any stock split, stock dividend, combination, or other recapitalization or reclassification
effected after the date hereof), the Company shall invite a representative of GIC to attend all meetings of its Board of Directors in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes,
consents, and other materials that it provides to its directors at the same time and in the same manner as provided to such directors; provided, however, that such representative shall agree to hold in confidence and trust and to act in a fiduciary
manner with respect to all information so provided; and provided further, that the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or
attendance at such meeting could adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest. 

2.6 Proprietary Information and Inventions Agreements. The Company shall require all current and former employees and consultants with
access to confidential information to execute and deliver a Proprietary Information and Inventions Agreement or Confidential Invention Inventions Assignment Agreement in substantially the form approved by the Company’s Board of Directors. 

2.7 Employee Agreements. Unless approved by the Board of Directors of the Company (including at least one of the Preferred Directors),
all future employees of the Company who shall purchase, or receive options to purchase, shares of Common Stock following the date hereof shall be 

  
 18 

 
required to execute stock purchase or option agreements providing for (a) vesting of shares over a four (4) year period with the first twenty five percent (25%) of such shares vesting
following twelve (12) months of continued employment or services, and the remaining shares vesting in equal monthly installments over the following thirty-six (36) months thereafter and (b) a
one hundred and eighty (180)-day lockup period in connection with the Initial Offering. Prior to a Liquidation Event, the Company shall not allow unvested shares to be transferred without unanimous approval of
the Board of Directors. The Company shall retain a right of first refusal on transfers until the Initial Offering or a Direct Listing and the right to repurchase unvested shares at cost. In addition, no acceleration of vesting of any stock options
or shares of Company Common Stock issued following the date of this Agreement, shall occur without the unanimous approval of the Board of Directors. 

2.8 Confidentiality. Each Investor agrees, severally and not jointly, to use the same degree of care as such Investor (other than GIC)
uses to protect its own confidential information (and, as to GIC, GIC agrees severally and not jointly to use the same degree of care GIC uses to protect confidential information from third parties in similar transactions and in any event no less
than reasonable care) for any information obtained pursuant to Section 2.1 or Section 2.2 hereof which the Company identifies in writing as being proprietary or confidential and such Investor acknowledges that it will not, unless otherwise
required by law or the rules of any national securities exchange, association or marketplace, disclose such information without the prior written consent of the Company except such information that (a) was in the public domain prior to the time
it was furnished to such Investor, (b) is or becomes (through no breach of this Agreement inaction by such Investor) generally available to the public, (c) was in its possession or known by such Investor without restriction prior to
receipt from the Company, (d) was disclosed to such Investor by a third party without restriction or (e) was independently developed without any use of the Company’s confidential information. Notwithstanding the foregoing, each
Investor may disclose such proprietary or confidential information to any former partners or members who retained an economic interest in such Investor, current or prospective partner of the partnership or any subsequent partnership under common
investment management, limited partner, general partner, member management company or Affiliate of such Investor (or any employee, officer, director, advisor, agent or representative of any of the foregoing) (each of the foregoing persons, a
“Permitted Disclosee”) or legal counsel, tax advisors, accountants or representatives for such Investor. Furthermore, nothing contained herein shall prevent any Investor or any Permitted Disclosee from (i) entering into any
business, entering into any agreement with a third party, or investing in or engaging in investment discussions with any other company (whether or not competitive with the Company), provided that such Investor or Permitted Disclosee does not, except
as permitted in accordance with this Section 2.8, disclose or otherwise make use of any proprietary or confidential information of the Company in connection with such activities, or (ii) making any disclosures required by law, rule,
regulation or court or other governmental order. Notwithstanding the foregoing, the Investors shall not be required to (i) disclose any of its or any Permitted Disclosee’s confidential information, (ii) disclose the identity of any
Permitted Disclosee or (iii) initiate or participate in any legal action, suit or proceeding involving the Company. 
 2.9
Anti-Corruption. The Company represents that it shall not, and shall not permit any of its subsidiaries or Affiliates or any of its or their respective directors, officers, managers, employees, independent contractors, representatives or
agents to, promise, authorize or make any payment to, or 

  
 19 

 
otherwise contribute any item of value, directly or indirectly, to any third party, including any Non-U.S. Official, in each case, in violation of the FCPA
(as defined in the Series F Agreement), the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. The Company further represents that it shall, and shall cause each of its subsidiaries and Affiliates to, cease all of its or
their respective activities, as well as remediate any actions taken by the Company, its Subsidiaries or Affiliates, or any of their respective directors, officers, managers, employees, independent contractors, representatives or agents in violation
of the Applicable Laws (as defined in the Purchase Agreement). The Company further represents that it shall, and shall cause each of its Subsidiaries and Affiliates to, maintain systems of internal controls (including, but not limited to, accounting
systems, purchasing systems and billing systems) to ensure compliance with Applicable Laws. The Company hereby agrees to notify GIC if any of the Relevant Parties (as defined in the Purchase Agreement) is investigated or becomes subject to a pending
or threatened investigation in relation to any Applicable Laws by any law enforcement, regulatory or other governmental agency or any customer or supplier and the outcome, when resolved, or any such proceedings. 

2.10 Right to Conduct Activities. The Company hereby agrees and acknowledges that certain of the Investors (including, without
limitation, GIC) are professional investment funds (the “Funds”), and as such invest in numerous portfolio companies, some of which may be deemed competitive with the Company’s business (as currently conducted or as currently
propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, the Funds shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by such Funds in any entity
competitive with the Company, or (ii) actions taken by any partner, officer or other representative of such Funds to assist any such competitive company, whether or not such action was taken as a member of the board of directors of such
competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) such Funds from liability associated with (1) the unauthorized disclosure
of the Company’s confidential information or (2) bad faith or willful misconduct on the part of the Funds or (y) any director of the Company appointed by such Funds from any liability associated with his or her fiduciary duties to the
Company. 
 2.11 Additional Agreements with GIC.  

(a) Notwithstanding anything in this Agreement to the contrary, in no event shall GIC be required to (i) provide any investor consent
letter, legal opinion, letter of credit or guarantee to, or execute any document, instrument or certificate for the benefit of, any potential lender to the Company (ii) initiate or participate in any legal action, suit or proceeding
(“Litigation”), against a third-party or (iii) absent GIC’s consent, participate in Litigation in which the Company is a party unless (and solely to the extent) compelled to do so by applicable law. 

(b) The Company (directly or indirectly through its Affiliates or otherwise) shall not disclose, orally or in writing, (i) any
confidential information furnished to them by GIC or its Affiliates or (ii) the name of GIC, any of its Affiliates or any derivative thereof to any third party in connection with GIC’s investment in the Company or any other matter
contemplated under this Agreement, the Purchase Agreement, or the other Ancillary Agreements (as defined in the Purchase Agreement); provided, however, the Company may disclose the ownership of the Company’s

  
 20 

 
equity securities by GIC to (a) the Company’s accountants, consultants, and other professionals and representatives to the extent necessary to obtain their services, (b) the
Company’s stockholders, (c) potential investors or acquirors in connection with a bona fide negotiation regarding a financing or acquisition of the Company or (d) as may be required by law, rule, regulation or other binding
governmental order. 
 2.12 Tax.  

(a) Without the prior written consent of GIC, for so long as GIC owns equity in the Company, the Company shall not be liquidated, merged,
converted into a limited liability company treated as a pass-through for U.S. federal income tax purposes, or otherwise enter into a transaction pursuant to which the Company ceases to exist as an entity treated as a corporation for U.S. federal
income tax purposes (and state and local income tax purposes, where applicable) without GIC’s prior written approval, such approval not to be unreasonably withheld, conditioned or delayed. 

(b) The Company (and its applicable withholding agents and paying agents) shall only be entitled to deduct and withhold taxes on any payments
to GIC to the extent required by applicable tax law; provided that, if the Company determines that an amount is required to be deducted and withheld with respect to GIC, at least ten (10) business days prior to the date the applicable payment
is scheduled to be made, the Company shall (i) provide GIC with written notice of the intent to deduct and withhold, the basis for withholding, and the amount of anticipated withholding, and (ii) provide GIC with a reasonable opportunity
to provide forms or other evidence that would exempt such amounts from withholding. 
 (c) The Company shall use commercially reasonable
efforts to avoid becoming a “United States real property holding corporation” within the meaning of Section 897(c)(2) of the United States Internal Revenue Code of 1986, as amended (the “Code”). The Company shall
provide prompt notice to GIC following the end of each taxable year of the Company or any other determination by the Company that the Company is or has become a “United States real property holding corporation” within the meaning of
Section 897(c)(2) of the Code. In addition, upon any reasonable written request by GIC, the Company shall provide GIC with a written statement informing GIC whether its interest in the Company constitutes a “United States real property
interest” within the meaning of Section 897(c)(2) of the Code. The Company’s determination shall comply with the requirements of Treasury Regulation Section 1.897-2(h)(1) or any successor
regulation, and the Company shall provide timely notice to the Internal Revenue Service, in accordance with and to the extent required by Treasury Regulation Section 1.897-2(h)(2) or any successor
regulation, that such statement has been made. The Company’s written statement to GIC shall be delivered within 10 business days of GIC’s written request therefor. The Company’s obligation to furnish such written statement shall
continue notwithstanding the fact that a class of the Company’s stock may be regularly traded on an established securities market or the fact that there is no Preferred Stock of the Company then outstanding. 

(d) The Company and GIC agree that it is their intention that (i) the Series E Preferred Stock shall be treated as stock that is not
“preferred stock” within the meaning of Section 305 of the Code and (ii) based on GIC’s equity interest in the Company as of the date hereof, the 

  
 21 

 
Company is not a “controlled commercial entity” with respect to GIC within the meaning of Section 892 of the Code. The Company agrees to take no positions or actions inconsistent
with such intended tax treatment (including on any IRS Form 1099), unless otherwise required by law, and in any such case the Company will notify GIC in writing prior to taking any position inconsistent with foregoing. The Company shall use

Agreement may be waived (either generally or in a particular instance and either retroactively or prospectively) only with the written consent of the Company and the Investors holding a majority of the Common Stock held by all Investors (assuming
full conversion, exchange and exercise of all Company securities convertible, exchangeable or exercisable into shares of Common Stock); provided, however, that in the event that such amendment or waiver adversely affects the
obligations or rights of the Common Holders in a different manner than the other Holders, such amendment or waiver shall also require the written consent of the Common Holders holding a majority of the shares of Common Stock held by all Common
Holders provided that amendments that merely add additional Investors to this Agreement shall not by itself be deemed as adversely affecting the obligations or rights of common Holders in a different manner than the other holders. The provisions of

  
 23 

 
Section 2.1, Section 2.2, Section 2.3, and Section 2.4 may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) only
with the written consent of the Company and the Major Investors holding a majority of the shares of Common Stock that are held by all of the Major Investors (assuming full conversion, exchange and exercise of all Company securities held by the Major
Investors that are convertible, exchangeable or exercisable into shares of Common Stock). The provisions of Section 2.5(a) may be amended or waived (either generally or in a particular instance and either retroactively or prospectively) only
with the written consent of the Company and IVP. The provisions of Sections 2.5(b), 2.8 (solely as it relates to GIC), 2.9, 2.11, 2.12, and this sentence may be amended or waived (either generally or in a particular instance and either retroactively
or prospectively) only with the written consent of the Company and GIC. Any amendment or waiver effected in accordance with this paragraph shall be binding upon each holder of any Registrable Securities, each future holder of all such Registrable
Securities and the Company. 
 3.8 Severability. Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement. 
 3.9 Aggregation of
Stock; Apportionment. All shares of Registrable Securities held or acquired by Affiliates, excluding any Registrable Securities held by an SPV Entity, shall be aggregated together for the purpose of determining the availability of any rights
under this Agreement and all such Affiliates may apportion such rights among them in their discretion. 
 3.10 Additional Investors.
Notwithstanding Section 3.7, no consent shall be necessary to add additional Investors as signatories to this Agreement, provided that such Investors have purchased Series F Preferred Stock pursuant to the subsequent closing provisions of
Section 1.3 of the Series F Agreement. 
 3.11 Dispute Resolution. Any unresolved controversy or claim arising out of or
relating to this Agreement, except as (i) otherwise provided in this Agreement, or (ii) any such controversies or claims arising out of either party’s intellectual property rights for which a provisional remedy or equitable relief is
sought, shall be submitted to arbitration by one arbitrator mutually agreed upon by the parties, and if no agreement can be reached within thirty (30) days after names of potential arbitrators have been proposed by the American Arbitration
Association (the “AAA”), then by one arbitrator having reasonable experience in corporate finance transactions of the type provided for in this Agreement and who is chosen by the AAA. The arbitration shall take place in the State of
California, County of San Francisco, in accordance with the AAA rules then in effect, and judgment upon any award rendered in such arbitration will be binding and may be entered in any court having jurisdiction thereof. There shall be limited
discovery prior to the arbitration hearing as follows: (a) exchange of witness lists and copies of documentary evidence and documents relating to or arising out of the issues to be arbitrated, (b) depositions of all party witnesses and
(c) such other depositions as may be allowed by the arbitrators upon a showing of good cause. Depositions shall be conducted in accordance with Section 3.2 hereof, the arbitrator shall be required to provide in writing to the parties the
basis for the award or order of such arbitrator, and a court reporter shall record all hearings, with such record constituting the official transcript of such proceedings. The prevailing party shall be entitled to reasonable attorney’s fees,
costs, and necessary disbursements in addition to any other relief to which such party may be entitled.

(as amended, the “Rights Agreement”) is made and entered into as of August 28, 2021 (the “Effective Date”) by and among Amplitude, Inc., a Delaware corporation (the “Company”), and the
Requisite Holders (as defined below). Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Rights Agreement. 

RECITAL 
 Pursuant to
Section 3.7 of the Rights Agreement, subject to certain provisions, the Rights Agreement and any term thereof may be amended or waived by written consent of the Company and the Investors holding a majority of the Common Stock held by all
Investors (assuming full conversion, exchange and exercise of all Company securities convertible, exchangeable or exercisable into shares of Common Stock) (the “Requisite Holders”). 

AGREEMENT 
 NOW,
THEREFORE, in consideration of the promises and mutual covenants and obligations hereinafter set forth, the Company and the Investors party hereto, constituting the Requisite Holders, hereby agree as follows: 

 

	 	1.	 Section 1.14 of the Rights Agreement is amended and restated to read in its entirety as follows:

 “1.14 Termination of Registration Rights. No Holder shall be entitled to exercise any right
provided for in this Section 1 (a) after five (5) years following the consummation of a Qualified Public Offering (as defined in the Restated Certificate), (b) as to any Holder, such earlier time after a Direct Listing or the Initial
Offering at which such Holder (i) can sell all shares held by it in compliance with Rule 144(b)(1)(i) or (ii) holds one percent (1%) or less of the Company’s outstanding Common Stock and all Registrable Securities held by such Holder
(together with any Affiliate of the Holder with whom such Holder must aggregate its sales under Rule 144) can be sold in any three (3) month period without registration in compliance with Rule 144 or (c) after the consummation of a
Liquidation Event pursuant to which the Investors receive cash and/or marketable securities.” 
  

	 	2.	 Except as specifically amended herein, the remaining terms and provisions of the Rights Agreement shall not be
affected by this Amendment and shall continue in full force and effect. 

  

	 	3.	 This Amendment shall be governed by and construed under the laws of the State of California as applied to
agreements among California residents entered into and to be performed entirely within California. 

	 	4.	 This Amendment may be executed in one or more counterparts, each of which shall be deemed an original, but all
of which together will constitute one and the same and shall become effective when one or more counterparts have been signed by each of the parties and delivered to the other party.

	SECTION 1.	 GENERAL PURPOSE OF THE PLAN; DEFINITIONS 

The name of the plan is the Amplitude, Inc. 2014 Stock Option and Grant Plan, as amended and restated December 30, 2014 (the
“Plan”). The purpose of the Plan is to encourage and enable the officers, employees, directors, Consultants and other key persons of Amplitude, Inc., a Delaware corporation (including any successor entity, the “Company”) and its
Subsidiaries, upon whose judgment, initiative and efforts the Company largely depends for the successful conduct of its business, to acquire a proprietary interest in the Company. 

The following terms shall be defined as set forth below: 

“Affiliate” of any Person means a Person that directly or indirectly, through one or more intermediaries, controls, is
controlled by or is under common control with the first mentioned Person. A Person shall be deemed to control another Person if such first Person possesses directly or indirectly the power to direct, or cause the direction of, the management and
policies of the second Person, whether through the ownership of voting securities, by contract or otherwise. 
 “Award” or
“Awards,” except where referring to a particular category of grant under the Plan, shall include Incentive Stock Options, Non-Qualified Stock Options, Restricted Stock Awards, Unrestricted
Stock Awards, Restricted Stock Units or any combination of the foregoing. 
 “Award Agreement” means a written or
electronic agreement setting forth the terms and provisions applicable to an Award granted under the Plan. Each Award Agreement may contain terms and conditions in addition to those set forth in the Plan; provided, however, in the event of
any conflict in the terms of the Plan and the Award Agreement, the terms of the Plan shall govern. 
 “Board” means
the Board of Directors of the Company. 
 “Cause” shall have the meaning as set forth in the Award Agreement(s). In the

customers, suppliers vendors or other third parties with which such entity does business; (ii) the grantee’s commission of (A) a felony or (B) any misdemeanor involving moral turpitude, deceit, dishonesty or fraud; (iii) the
grantee’s failure to perform his assigned duties and responsibilities to the reasonable satisfaction of the Company which failure continues, in the reasonable judgment of the Company, after written notice given to the grantee by the Company;
(iv) the grantee’s gross negligence, willful misconduct or insubordination with respect to the Company or any Affiliate of the Company; or (v) the grantee’s material violation of any provision of any agreement(s) between the
grantee and the Company relating to noncompetition, nonsolicitation, nondisclosure and/or assignment of inventions.

Committee of the Board referred to in Section 2. 
 “Consultant” means any natural person that provides bona fide
services to the Company (including a Subsidiary), and such services are not in connection with the offer or sale of securities in a capital-raising transaction and do not directly or indirectly promote or maintain a market for the Company’s
securities.

“Effective Date” means the date on which the Plan is adopted as set forth on the final page of the Plan.

Committee based on the reasonable application of a reasonable valuation method not inconsistent with Section 409A of the Code. If the Stock is admitted to trade on a national securities exchange, the determination shall be made by reference to
the closing price reported on such exchange. If there is no closing price for such date, the determination shall be made by reference to the last date preceding such date for which there is a closing price. If the date for which Fair Market Value is
determined is the first day when trading prices for the Stock are reported on a national securities exchange, the Fair Market Value shall be the “Price to the Public” (or equivalent) set forth on the cover page for the final prospectus
relating to the Company’s Initial Public Offering. 
 “Good Reason” shall have the meaning as set forth in the Award
Agreement(s). In the case that any Award Agreement does not contain a definition of “Good Reason,” it shall mean (i) a material diminution in the grantee’s base salary except for across-the-board salary reductions similarly affecting all or substantially all similarly situated employees of the Company or (ii) a change of more than 50 miles in the geographic location at which the
grantee provides services to the Company, so long as the grantee provides at least 90 days notice to the Company following the initial occurrence of any such event and the Company fails to cure such event within 30 days thereafter. 

“Grant Date” means the date that the Committee designates in its approval of an Award in accordance with applicable law as
the date on which the Award is granted, which date may not precede the date of such Committee approval.

shares of Stock granted pursuant to Section 5.

distribution of any Shares during the term of the Award Agreement unless subject to its terms. Upon the death of the Holder, the term Permitted Transferees shall also include such deceased Holder’s estate, executors, administrators, personal
representatives, heirs, legatees and distributees, as the case may be. 
 “Person” shall mean any individual, corporation,
partnership (limited or general), limited liability company, limited liability partnership, association, trust, joint venture, unincorporated organization or any similar entity.

consolidation pursuant to which the holders of the Company’s outstanding voting power immediately prior to such transaction do not own a majority of the outstanding voting power of the surviving or resulting entity (or its ultimate parent, if
applicable), (iv) the acquisition of all or a majority of the outstanding voting stock of the Company in a single transaction or a series of related transactions by a Person or group of Persons, or (v) any other acquisition of the business of
the Company, as determined by the Board; provided, however, that the Company’s Initial Public Offering, any subsequent public offering or another capital raising event, or a merger effected solely to change the Company’s domicile
shall not constitute a “Sale Event.”

service or sickness, or for any other purpose approved by the Committee, if the individual’s right to re-employment is guaranteed either by a statute or by contract or under the policy pursuant to which

by a committee of the Board, comprised of not less than two directors. All references herein to the “Committee” shall be deemed to refer to the group then responsible for administration of the Plan at the relevant time (i.e., either the
Board of Directors or a committee or committees of the Board, as applicable). 

  

	(b)	 Powers of Committee. The Committee shall have the power and authority to grant Awards consistent with
the terms of the Plan, including the power and authority: 

 (i)    to select the individuals to whom
Awards may from time to time be granted; 

  
 4 

 (ii)    to determine the time or times of grant, and the amount, if any,
of Incentive Stock Options, Non-Qualified Stock Options, Restricted Stock Awards, Unrestricted Stock Awards, Restricted Stock Units, or any combination of the foregoing, granted to any one or more grantees;

 (iii)    to determine the number of Shares to be covered by any Award and, subject to the provisions of the Plan, the
price, exercise price, conversion ratio or other price relating thereto; 
 (iv)    to determine and, subject to
Section 12, to modify from time to time the terms and conditions, including restrictions, not inconsistent with the terms of the Plan, of any Award, which terms and conditions may differ among individual Awards and grantees, and to approve the
form of Award Agreements; 
 (v)    to accelerate at any time the exercisability or vesting of all or any portion of any
Award; 
 (vi)    to impose any limitations on Awards, including limitations on transfers, repurchase provisions and the
like, and to exercise repurchase rights or obligations; 
 (vii)    subject to Section 5(a)(ii) and any
restrictions imposed by Section 409A, to extend at any time the period in which Stock Options may be exercised; and 

(viii)    at any time to adopt, alter and repeal such rules, guidelines and practices for administration of the Plan and
for its own acts and proceedings as it shall deem advisable; to interpret the terms and provisions of the Plan and any Award (including Award Agreements); to make all determinations it deems advisable for the administration of the Plan; to decide
all disputes arising in connection with the Plan; and to otherwise supervise the administration of the Plan. 
 All decisions and interpretations of the
Committee shall be binding on all persons, including the Company and all Holders. 
 (c)    Award Agreement.
Awards under the Plan shall be evidenced by Award Agreements that set forth the terms, conditions and limitations for each Award. 

(d)    Indemnification. Neither the Board nor the Committee, nor any member of either or any delegate thereof,
shall be liable for any act, omission, interpretation, construction or determination made in good faith in connection with the Plan, and the members of the Board and the Committee (and any delegate thereof) shall be entitled in all cases to
indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including, without limitation, reasonable attorneys’ fees) arising or resulting therefrom to the fullest extent permitted by law and/or under the
Company’s governing documents, including its certificate of incorporation or bylaws, or any directors’ and officers’ liability insurance coverage which may be in effect from time to time and/or any indemnification agreement between
such individual and the Company. 

  
 5 

 (e)    Foreign Award Recipients. Notwithstanding any provision of
the Plan to the contrary, in order to comply with the laws in other countries in which the Company and any Subsidiary operate or have employees or other individuals eligible for Awards, the Committee, in its sole discretion, shall have the power and
authority to: (i) determine which Subsidiaries, if any, shall be covered by the Plan; (ii) determine which individuals, if any, outside the United States are eligible to participate in the Plan; (iii) modify the terms and conditions
of any Award granted to individuals outside the United States to comply with applicable foreign laws; (iv) establish subplans and modify exercise procedures and other terms and procedures, to the extent the Committee determines such actions to
be necessary or advisable (and such subplans and/or modifications shall be attached to the Plan as appendices); provided, however, that no such subplans and/or modifications shall increase the share limitation contained in
Section 3(a) hereof; and (v) take any action, before or after an Award is made, that the Committee determines to be necessary or advisable to obtain approval or comply with any local governmental regulatory exemptions or approvals. 

 

	SECTION 3.	 STOCK ISSUABLE UNDER THE PLAN; MERGERS AND OTHER TRANSACTIONS; SUBSTITUTION 

(a)    Stock Issuable. The maximum number of Shares reserved and available for issuance under the Plan shall be
46,406,328 Shares, subject to adjustment as provided in Section 3(b). For purposes of this limitation, the Shares underlying any Awards that are forfeited, canceled, reacquired by the Company prior to vesting, satisfied without the issuance of
Stock or otherwise terminated (other than by exercise) and Shares that are withheld upon exercise of an Option or settlement of an Award to cover the exercise price or tax withholding shall be added back to the Shares available for issuance under
the Plan. Subject to such overall limitations, Shares may be issued up to such maximum number pursuant to any type or types of Award, and no more than 464,063,280 Shares may be issued pursuant to Incentive Stock Options. The Shares available for
issuance under the Plan may be authorized but unissued Shares or Shares reacquired by the Company. Beginning on the date that the Company becomes subject to Section 162(m) of the Code, Options with respect to no more than 46,406,328 Shares
shall be granted to any one individual in any calendar year period. 
 (b)    Changes in Stock. Subject to
Section 3(c) hereof, if, as a result of any reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock, the outstanding Shares are increased
or decreased or are exchanged for a different number or kind of shares or other securities of the Company, or additional Shares or new or different shares or other securities of the Company or other non-cash
assets are distributed with respect to such Shares or other securities, in each case, without the receipt of consideration by the 

  
 6 

 
Company, or, if, as a result of any merger or consolidation, or sale of all or substantially all of the assets of the Company, the outstanding Shares are converted into or exchanged for other
securities of the Company or any successor entity (or a parent or subsidiary thereof), the Committee shall make an appropriate and proportionate adjustment in (i) the maximum number of Shares reserved for issuance under the Plan, (ii) the
number and kind of Shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price, if any, per Share subject to each outstanding Award, and (iv) the exercise price for each Share subject to any
then outstanding Stock Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number of Stock Options) as to which such Stock Options remain exercisable. The Committee shall in any event
make such adjustments as may be required by Section 25102(o) of the California Corporation Code and the rules and regulations promulgated thereunder. The adjustment by the Committee shall be final, binding and conclusive. No fractional Shares
shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion may make a cash payment in lieu of fractional shares. 

(c)    Sale Events. 
  

	 	(i)	 Options. 

(A)    In the case of and subject to the consummation of a Sale Event, the Plan and all outstanding Options
issued hereunder shall terminate upon the effective time of any such Sale Event unless assumed or continued by the successor entity, or new stock options or other awards of the successor entity or parent thereof are substituted therefor, with an
equitable or proportionate adjustment as to the number and kind of shares and, if appropriate, the per share exercise prices, as such parties shall agree (after taking into account any acceleration hereunder and/or pursuant to the terms of any Award
Agreement). 
 (B)    In the event of the termination of the Plan and all outstanding Options issued
hereunder pursuant to Section 3(c), each Holder of Options shall be permitted, within a period of time prior to the consummation of the Sale Event as specified by the Committee, to exercise all such Options which are then vested and exercisable
or will become vested and exercisable as of the effective time of the Sale Event; provided, however, that the exercise of Options not exercisable prior to the Sale Event shall be subject to the consummation of the Sale Event. 

(C)    Notwithstanding anything to the contrary in Section 3(c)(i)(A), in the event of a Sale Event,
the Company shall have the right, but not the obligation, to make or provide for a cash payment to the Holders of Options, without any consent of the Holders, in exchange for the cancellation thereof, in an amount equal to the difference between
(A) the value as determined by the Committee of the consideration payable per share of Stock pursuant to the Sale Event (the “Sale Price”) times the number of Shares subject to outstanding Options being cancelled (to the extent then
vested and exercisable, including by reason of acceleration in connection with such Sale Event, at prices not in excess of the Sale Price) and (B) the aggregate exercise price of all such outstanding vested and exercisable Options. 

  
 7 

 (D)    For avoidance of doubt, the Committee may cancel
Options, to the extent not vested immediately prior to the consummation of the Sale Event, without the payment of consideration. The Committee need not take the same action or actions with respect to all Awards or portions thereof or with respect to
all grantees. The Committee may take different actions with respect to the vested and unvested portions of an Award. 
  

	 	(ii)	 Restricted Stock and Restricted Stock Unit Awards. 

(A)    In the case of and subject to the consummation of a Sale Event, all unvested Restricted Stock and
unvested Restricted Stock Unit Awards (other than those becoming vested as a result of the Sale Event) issued hereunder shall be forfeited immediately prior to the effective time of any such Sale Event unless assumed or continued by the successor
entity, or awards of the successor entity or parent thereof are substituted therefor, with an equitable or proportionate adjustment as to the number and kind of shares subject to such awards as such parties shall agree (after taking into account any
acceleration hereunder and/or pursuant to the terms of any Award Agreement). 
 (B)    In the event of
the forfeiture of Restricted Stock pursuant to Section 3(c)(ii)(A), such Restricted Stock shall be repurchased from the Holder thereof at a price per share equal to the original per share purchase price paid by the Holder (subject to adjustment
as provided in Section 3(b)) for such Shares. 
 (C)    Notwithstanding anything to the contrary in
Section 3(c)(ii)(A), in the event of a Sale Event, the Company shall have the right, but not the obligation, to make or provide for a cash payment to the Holders of Restricted Stock or Restricted Stock Unit Awards, without consent of the
Holders, in exchange for the cancellation thereof, in an amount equal to the Sale Price times the number of Shares subject to such Awards, to be paid at the time of such Sale Event or upon the later vesting of such Awards. 

 

	SECTION 4.	 ELIGIBILITY 

Grantees under the Plan will be such full or part-time officers and other employees, directors, Consultants and key persons of the Company and
any Subsidiary who are selected from time to time by the Committee in its sole discretion; provided, however, that Awards shall be granted only to those individuals described in Rule 701(c) of the Securities Act. 

 

	SECTION 5.	 STOCK OPTIONS 

Upon the grant of a Stock Option, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each such Award
Agreement shall be determined by the Committee, and such terms and conditions may differ among individual Awards and grantees. 
 Stock
Options granted under the Plan may be either Incentive Stock Options or Non- Qualified Stock Options. Incentive Stock Options may be granted only to employees of the Company or any Subsidiary that is a “subsidiary corporation” within the
meaning of Section 424(f) of the Code. To the extent that any Option does not qualify as an Incentive Stock Option, it shall be deemed a Non-Qualified Stock Option. 

  
 8 

 (a)    Terms of Stock Options. The Committee in its discretion
may grant Stock Options to those individuals who meet the eligibility requirements of Section 4. Stock Options shall be subject to the following terms and conditions and shall contain such additional terms and conditions, not inconsistent with
the terms of the Plan, as the Committee shall deem desirable. 
 (i)    Exercise Price. The exercise price per
share for the Shares covered by a Stock Option shall be determined by the Committee at the time of grant but shall not be less than 100 percent of the Fair Market Value on the Grant Date. In the case of an Incentive Stock Option that is granted
to a Ten Percent Owner, the exercise price per share for the Shares covered by such Incentive Stock Option shall not be less than 110 percent of the Fair Market Value on the Grant Date. 

(ii)    Option Term. The term of each Stock Option shall be fixed by the Committee, but no Stock Option shall be
exercisable more than ten years from the Grant Date. In the case of an Incentive Stock Option that is granted to a Ten Percent Owner, the term of such Stock Option shall be no more than five years from the Grant Date. 

(iii)    Exercisability; Rights of a Stockholder. Stock Options shall become exercisable and/or vested at such time
or times, whether or not in installments, as shall be determined by the Committee at or after the Grant Date. The Award Agreement may permit a grantee to exercise all or a portion of a Stock Option immediately at grant; provided that the Shares
issued upon such exercise shall be subject to restrictions and a vesting schedule identical to the vesting schedule of the related Stock Option, such Shares shall be deemed to be Restricted Stock for purposes of the Plan, and the optionee may be
required to enter into an additional or new Award Agreement as a condition to exercise of such Stock Option. An optionee shall have the rights of a stockholder only as to Shares acquired upon the exercise of a Stock Option and not as to unexercised
Stock Options. An optionee shall not be deemed to have acquired any Shares unless and until a Stock Option shall have been exercised pursuant to the terms of the Award Agreement and this Plan and the optionee’s name has been entered on the
books of the Company as a stockholder. 
 (iv)    Method of Exercise. Stock Options may be exercised by an
optionee in whole or in part, by the optionee giving written or electronic notice of exercise to the Company, specifying the number of Shares to be purchased. Payment of the purchase price may be made by one or more of the following methods (or any
combination thereof) to the extent provided in the Award Agreement: 
 (A)    In cash, by certified or
bank check, by wire transfer of immediately available funds, or other instrument acceptable to the Committee; 

(B)    If permitted by the Committee, by the optionee delivering to the Company a promissory note, if the
Board has expressly authorized the loan of funds to the optionee for the purpose of enabling or assisting the optionee to effect the exercise of his or her Stock Option; provided, that at least so much of the exercise price as represents the
par value of the Stock shall be paid in cash if required by state law; 

  
 9 

 (C)    If permitted by the Committee and the Initial
Public Offering has occurred (or the Stock otherwise becomes publicly-traded), through the delivery (or attestation to the ownership) of Shares that have been purchased by the optionee on the open market or that are beneficially owned by the
optionee and are not then subject to restrictions under any Company plan. To the extent required to avoid variable accounting treatment under ASC 718 or other applicable accounting rules, such surrendered Shares if originally purchased from the
Company shall have been owned by the optionee for at least six months. Such surrendered Shares shall be valued at Fair Market Value on the exercise date; 

(D)    If permitted by the Committee and the Initial Public Offering has occurred (or the Stock otherwise
becomes publicly-traded), by the optionee delivering to the Company a properly executed exercise notice together with irrevocable instructions to a broker to promptly deliver to the Company cash or a check payable and acceptable to the Company for
the purchase price; provided that in the event the optionee chooses to pay the purchase price as so provided, the optionee and the broker shall comply with such procedures and enter into such agreements of indemnity and other agreements as
the Committee shall prescribe as a condition of such payment procedure; or 
 (E)    If permitted by the
Committee, and only with respect to Stock Options that are not Incentive Stock Options, by a “net exercise” arrangement pursuant to which the Company will reduce the number of Shares issuable upon exercise by the largest whole number of
Shares with a Fair Market Value that does not exceed the aggregate exercise price. 
 Payment instruments will be received subject to
collection. No certificates for Shares so purchased will be issued to the optionee or, with respect to uncertificated Stock, no transfer to the optionee on the records of the Company will take place, until the Company has completed all steps it has
deemed necessary to satisfy legal requirements relating to the issuance and sale of the Shares, which steps may include, without limitation, (i) receipt of a representation from the optionee at the time of exercise of the Option that the
optionee is purchasing the Shares for the optionee’s own account and not with a view to any sale or distribution of the Shares or other representations relating to compliance with applicable law governing the issuance of securities, (ii) the
legending of the certificate (or notation on any book entry) representing the Shares to evidence the foregoing restrictions, and (iii) obtaining from optionee payment or provision for all withholding taxes due as a result of the exercise of the
Option. The delivery of certificates representing the shares of Stock (or the transfer to the optionee on the records of the Company with respect to uncertificated Stock) to be purchased pursuant to the exercise of a Stock Option will be contingent
upon (A) receipt from the optionee (or a purchaser acting in his or her stead in accordance with the provisions of the Stock Option) by the Company of the full purchase price for such Shares and the fulfillment of any other requirements
contained in the Award Agreement or applicable provisions of laws and (B) if required by the Company, the optionee shall have entered into any stockholders agreements or other agreements with the Company and/or certain other of the
Company’s stockholders relating to the Stock. In the event an optionee chooses to pay the purchase price by previously-owned Shares through the attestation method, the number of Shares transferred to the optionee upon the exercise of the Stock
Option shall be net of the number of Shares attested to. 

  
 10 

 (b)    Annual Limit on Incentive Stock Options. To the extent
required for “incentive stock option” treatment under Section 422 of the Code, the aggregate Fair Market Value (determined as of the Grant Date) of the Shares with respect to which Incentive Stock Options granted under the Plan and
any other plan of the Company or its parent and any Subsidiary that become exercisable for the first time by an optionee during any calendar year shall not exceed $100,000 or such other limit as may be in effect from time to time under
Section 422 of the Code. To the extent that any Stock Option exceeds this limit, it shall constitute a Non-Qualified Stock Option. 

(c)    Termination. Any portion of a Stock Option that is not vested and exercisable on the date of termination of
an optionee’s Service Relationship shall immediately expire and be null and void. Once any portion of the Stock Option becomes vested and exercisable, the optionee’s right to exercise such portion of the Stock Option (or the
optionee’s representatives and legatees as applicable) in the event of a termination of the optionee’s Service Relationship shall continue until the earliest of: (i) the date which is: (A) 12 months following the date on which the
optionee’s Service Relationship terminates due to death or Disability (or such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (B) three months following the date on which the
optionee’s Service Relationship terminates if the termination is due to any reason other than death or Disability (or such longer period of time as determined by the Committee and set forth in the applicable Award Agreement), or (ii) the
Expiration Date set forth in the Award Agreement; provided that notwithstanding the foregoing, an Award Agreement may provide that if the optionee’s Service Relationship is terminated for Cause, the Stock Option shall terminate immediately and
be null and void upon the date of the optionee’s termination and shall not thereafter be exercisable. 
  

	SECTION 6.	 RESTRICTED STOCK AWARDS 

(a)    Nature of Restricted Stock Awards. The Committee may, in its sole discretion, grant (or sell at par value or
such other purchase price determined by the Committee) to an eligible individual under Section 4 hereof a Restricted Stock Award under the Plan. The Committee shall determine the restrictions and conditions applicable to each Restricted Stock
Award at the time of grant. Conditions may be based on continuing employment (or other Service Relationship), achievement of pre-established performance goals and objectives and/or such other criteria as the
Committee may determine. Upon the grant of a Restricted Stock Award, the Company and the grantee shall enter into an Award Agreement. The terms and conditions of each such Award Agreement shall be determined by the Committee, and such terms and
conditions may differ among individual Awards and grantees. 
 (b)    Rights as a Stockholder. Upon the grant of
the Restricted Stock Award and payment of any applicable purchase price, a grantee of Restricted Stock shall be considered the record owner of and shall be entitled to vote the Restricted Stock if, and to the extent, such Shares are entitled to
voting rights, subject to such conditions contained in the Award Agreement. The grantee shall be entitled to receive all dividends and any other distributions 

  
 11 

 declared on the Shares; provided, however, that the Company is under no duty to declare any
such dividends or to make any such distribution. Unless the Committee shall otherwise determine, certificates evidencing the Restricted Stock shall remain in the possession of the Company until such Restricted Stock is vested as provided in
subsection (d) below of this Section, and the grantee shall be required, as a condition of the grant, to deliver to the Company a stock power endorsed in blank and such other instruments of transfer as the Committee may prescribe. 

(c)    Restrictions. Restricted Stock may not be sold, assigned, transferred, pledged or otherwise encumbered or
disposed of except as specifically provided herein or in the Award Agreement. Except as may otherwise be provided by the Committee either in the Award Agreement or, subject to Section 12 below, in writing after the Award Agreement is issued, if
a grantee’s Service Relationship with the Company and any Subsidiary terminates, the Company or its assigns shall have the right, as may be specified in the relevant instrument, to repurchase some or all of the Shares subject to the Award at
such purchase price as is set forth in the Award Agreement. 
 (d)    Vesting of Restricted Stock. The Committee
at the time of grant shall specify in the Award Agreement the date or dates and/or the attainment of pre-established performance goals, objectives and other conditions on which the substantial risk of
forfeiture imposed shall lapse and the Restricted Stock shall become vested, subject to such further rights of the Company or its assigns as may be specified in the Award Agreement. 

 

	SECTION 7.	 UNRESTRICTED STOCK AWARDS 

The Committee may, in its sole discretion, grant (or sell at par value or such other purchase price determined by the Committee) to an eligible
person under Section 4 hereof an Unrestricted Stock Award under the Plan. Unrestricted Stock Awards may be granted in respect of past services or other valid consideration, or in lieu of cash compensation due to such grantee. 

 

	SECTION 8.	 RESTRICTED STOCK UNITS 

(a)    Nature of Restricted Stock Units. The Committee may, in its sole discretion, grant to an eligible person
under Section 4 hereof Restricted Stock Units under the Plan. The Committee shall determine the restrictions and conditions applicable to each Restricted Stock Unit at the time of grant. Vesting conditions may be based on continuing employment
(or other Service Relationship), achievement of pre-established performance goals and objectives and/or other such criteria as the Committee may determine. Upon the grant of Restricted Stock Units, the grantee
and the Company shall enter into an Award Agreement. The terms and conditions of each such Award Agreement shall be determined by the Committee and may differ among individual Awards and grantees. On or promptly following the vesting date or dates
applicable to any Restricted Stock Unit, but in no event later than March 15 of the year following the year in which such vesting occurs, such Restricted Stock Unit(s) shall be settled in the form of cash or shares of Stock, as specified in the
Award Agreement. Restricted Stock Units may not be sold, assigned, transferred, pledged, or otherwise encumbered or disposed of. 

  
 12 

 (b)    Rights as a Stockholder. A grantee shall have the rights
of a stockholder only as to Shares, if any, acquired upon settlement of Restricted Stock Units. A grantee shall not be deemed to have acquired any such Shares unless and until the Restricted Stock Units shall have been settled in Shares pursuant to
the terms of the Plan and the Award Agreement, the Company shall have issued and delivered a certificate representing the Shares to the grantee (or transferred on the records of the Company with respect to uncertificated stock), and the
grantee’s name has been entered in the books of the Company as a stockholder. 
 (c)    Termination. Except
as may otherwise be provided by the Committee either in the Award Agreement or in writing after the Award Agreement is issued, a grantee’s right in all Restricted Stock Units that have not vested shall automatically terminate upon the
grantee’s cessation of Service Relationship with the Company and any Subsidiary for any reason. 
  

	SECTION 9.	 TRANSFER RESTRICTIONS; COMPANY RIGHT OF FIRST REFUSAL; COMPANY REPURCHASE RIGHTS 

 

	 	(a)	 Restrictions on Transfer. 

(i)    Non-Transferability of Stock Options. Stock Options and, prior to
exercise, the Shares issuable upon exercise of such Stock Option, shall not be transferable by the optionee otherwise than by will, or by the laws of descent and distribution, and all Stock Options shall be exercisable, during the optionee’s
lifetime, only by the optionee, or by the optionee’s legal representative or guardian in the event of the optionee’s incapacity. Notwithstanding the foregoing, the Committee, in its sole discretion, may provide in the Award Agreement
regarding a given Stock Option that the optionee may transfer by gift, without consideration for the transfer, his or her Non-Qualified Stock Options to his or her family members (as defined in Rule 701 of the
Securities Act), to trusts for the benefit of such family members, or to partnerships in which such family members are the only partners (to the extent such trusts or partnerships are considered “family members” for purposes of Rule 701 of
the Securities Act), provided that the transferee agrees in writing with the Company to be bound by all of the terms and conditions of this Plan and the applicable Award Agreement, including the execution of a stock power upon the issuance of
Shares. Stock Options, and the Shares issuable upon exercise of such Stock Options, shall be restricted as to any pledge, hypothecation, or other transfer, including any short position, any “put equivalent position” (as defined in the
Exchange Act) or any “call equivalent position” (as defined in the Exchange Act) prior to exercise. 

  
 13 

 (ii)    Shares. No Shares shall be sold, assigned, transferred,
pledged, hypothecated, given away or in any other manner disposed of or encumbered, whether voluntarily or by operation of law, unless (i) the transfer is in compliance with the terms of the applicable Award Agreement, all applicable securities
laws (including, without limitation, the Securities Act), and with the terms and conditions of this Section 9, (ii) the transfer does not cause the Company to become subject to the reporting requirements of the Exchange Act, and (iii) the
transferee consents in writing to be bound by the provisions of the Plan and the Award Agreement, including this Section 9. In connection with any proposed transfer, the Committee may require the transferor to provide at the transferor’s
own expense an opinion of counsel to the transferor, satisfactory to the Committee, that such transfer is in compliance with all foreign, federal and state securities laws (including, without limitation, the Securities Act). Any attempted transfer
of Shares not in accordance with the terms and conditions of this Section 9 shall be null and void, and the Company shall not reflect on its records any change in record ownership of any Shares as a result of any such transfer, shall otherwise
refuse to recognize any such transfer and shall not in any way give effect to any such transfer of Shares. The Company shall be entitled to seek protective orders, injunctive relief and other remedies available at law or in equity including, without
limitation, seeking specific performance or the rescission of any transfer not made in strict compliance with the provisions of this Section 9. Subject to the foregoing general provisions, and unless otherwise provided in the applicable Award
Agreement, Shares may be transferred pursuant to the following specific terms and conditions (provided that with respect to any transfer of Restricted Stock, all vesting and forfeiture provisions shall continue to apply with respect to the original
recipient): 
 (A)    Transfers to Permitted Transferees. The Holder may transfer any or all of
the Shares to one or more Permitted Transferees; provided, however, that following such transfer, such Shares shall continue to be subject to the terms of this Plan (including this Section 9) and such Permitted Transferee(s)
shall, as a condition to any such transfer, deliver a written acknowledgment to that effect to the Company and shall deliver a stock power to the Company with respect to the Shares. Notwithstanding the foregoing, the Holder may not transfer any of
the Shares to a Person whom the Company reasonably determines is a direct competitor or a potential competitor of the Company or any of its Subsidiaries. 

(B)    Transfers Upon Death. Upon the death of the Holder, any Shares then held by the Holder at the
time of such death and any Shares acquired after the Holder’s death by the Holder’s legal representative shall be subject to the provisions of this Plan, and the Holder’s estate, executors, administrators, personal representatives,
heirs, legatees and distributees shall be obligated to convey such Shares to the Company or its assigns under the terms contemplated by the Plan and the Award Agreement. 

(b)    Right of First Refusal. In the event that a Holder desires at any time to sell or otherwise transfer all or
any part of his or her Shares (other than shares of Restricted Stock which by their terms are not transferrable), the Holder first shall give written notice to the Company of the Holder’s intention to make such transfer. Such notice shall state
the number of Shares that the Holder proposes to sell (the “Offered Shares”), the price and the terms at which the proposed sale is to be made and the name and address of the proposed transferee. At any time within 30 days after the
receipt of such notice by the Company, the Company or its assigns may elect to purchase all or any portion of the Offered Shares at the price and on the terms offered by the proposed transferee and specified in the notice. The Company or its assigns
shall exercise this right by mailing or delivering written notice to the Holder within the foregoing 30- day period. If the Company or its assigns elect to exercise its purchase rights under this Section 9(b), the closing for such purchase
shall, in any event, take place within 45 days after the receipt by the Company of the initial notice from the Holder. In the event that the Company or its assigns do not elect to exercise such purchase right, or in the event that the Company or its
assigns do not pay the full purchase price within such 45-day period, the Holder shall be required to pay a transaction processing fee of $10,000 to the Company (unless waived by the Committee) and then may,
within 60 days thereafter, sell the Offered Shares to the proposed transferee and at the same price and on the same terms as specified in the Holder’s notice. Any Shares not sold to the proposed transferee shall remain subject to the Plan. If
the Holder is a party to any stockholders agreements or other agreements with the Company and/or certain other of the Company’s stockholders relating to the Shares, (i) the transferring Holder shall comply with the requirements of such
stockholders agreements or other agreements relating to any proposed transfer of the Offered Shares, and (ii) any proposed transferee that purchases Offered Shares shall enter into such stockholders agreements or other agreements with the
Company and/or certain of the Company’s stockholders relating to the Offered Shares on the same terms and in the same capacity as the transferring Holder. 

  
 14 

	 	(c)	 Company’s Right of Repurchase. 

(i)    Right of Repurchase for Unvested Shares Issued Upon the Exercise of an Option. Upon a Termination
Event, the Company or its assigns shall have the right and option to repurchase from a Holder of Shares acquired upon exercise of a Stock Option which are still subject to a risk of forfeiture as of the Termination Event. Such repurchase rights may
be exercised by the Company within the later of (A) six months following the date of such Termination Event or (B) seven months after the acquisition of Shares upon exercise of a Stock Option. The repurchase price shall be equal to the
lower of the original per share price paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights. 

(ii)    Right of Repurchase With Respect to Restricted Stock. Upon a Termination Event, the Company or its assigns
shall have the right and option to repurchase from a Holder of Shares received pursuant to a Restricted Stock Award any Shares that are still subject to a risk of forfeiture as of the Termination Event. Such repurchase right may be exercised by the
Company within six months following the date of such Termination Event. The repurchase price shall be the lower of the original per share purchase price paid by the Holder, subject to adjustment as provided in Section 3(b) of the Plan, or the
current Fair Market Value of such Shares as of the date the Company elects to exercise its repurchase rights. 

(iii)    Procedure. Any repurchase right of the Company shall be exercised by the Company or its assigns by giving
the Holder written notice on or before the last day of the repurchase period of its intention to exercise such repurchase right. Upon such notification, the Holder shall promptly surrender to the Company, free and clear of any liens or encumbrances,
any certificates representing the Shares being purchased, together with a duly executed stock power for the transfer of such Shares to the Company or the Company’s assignee or assignees. Upon the Company’s or its assignee’s receipt of
the certificates from the Holder, the Company or its assignee or assignees shall deliver to him, her or them a check for the applicable repurchase price; provided, however, that the Company may pay the repurchase price by offsetting and
canceling any indebtedness then owed by the Holder to the Company. 
  

	 	(d)	 Reserved. 

  

	 	(e)	 Escrow Arrangement. 

(i)    Escrow. In order to carry out the provisions of this Section 9 of this Plan more effectively, the
Company shall hold any Shares issued pursuant to Awards granted under the Plan in escrow together with separate stock powers executed by the Holder in blank for transfer. The Company shall not dispose of the Shares except as otherwise provided in
this Plan. In the event of any repurchase by the Company (or any of its assigns), the Company is hereby authorized by the Holder, as the Holder’s attorney-in-fact,
to date and complete the stock powers necessary for the transfer of the Shares being purchased and to transfer such Shares in accordance with the terms hereof. At such time as any Shares are no longer subject to the Company’s repurchase and
first refusal rights, the Company shall, at the written request of the Holder, deliver to the Holder a certificate representing such Shares with the balance of the Shares to be held in escrow pursuant to this Section. 

  
 15 

 (ii)    Remedy. Without limitation of any other provision of this
Plan or other rights, in the event that a Holder or any other Person is required to sell a Holder’s Shares pursuant to the provisions of Sections 9(b) or (c) hereof and in the further event that he or she refuses or for any reason fails to
deliver to the Company or its designated purchaser of such Shares the certificate or certificates evidencing such Shares together with a related stock power, the Company or such designated purchaser may deposit the applicable purchase price for such
Shares with a bank designated by the Company, or with the Company’s independent public accounting firm, as agent or trustee, or in escrow, for such Holder or other Person, to be held by such bank or accounting firm for the benefit of and for
delivery to him, her, them or it, and/or, in its discretion, pay such purchase price by offsetting any indebtedness then owed by such Holder as provided above. Upon any such deposit and/or offset by the Company or its designated purchaser of such
amount and upon notice to the Person who was required to sell the Shares to be sold pursuant to the provisions of Sections 9(b) or (c), such Shares shall at such time be deemed to have been sold, assigned, transferred and conveyed to such purchaser,
such Holder shall have no further rights thereto (other than the right to withdraw the payment thereof held in escrow, if applicable), and the Company shall record such transfer in its stock transfer book or in any appropriate manner. 

(f)    Lockup Provision. If requested by the Company, a Holder shall not sell or otherwise transfer or dispose of
any Shares (including, without limitation, pursuant to Rule 144 under the Securities Act) held by him or her for such period following the effective date of a public offering by the Company of Shares as the Company shall specify reasonably and in
good faith. If requested by the underwriter engaged by the Company, each Holder shall execute a separate letter confirming his or her agreement to comply with this Section. 

(g)    Adjustments for Changes in Capital Structure. If, as a result of any reorganization, recapitalization,
reclassification, stock dividend, stock split, reverse stock split or other similar change in the Common Stock, the outstanding Shares are increased or decreased or are exchanged for a different number or kind of securities of the Company, the
restrictions contained in this Section 9 shall apply with equal force to additional and/or substitute securities, if any, received by Holder in exchange for, or by virtue of his or her ownership of, Shares. 

(h)    Termination. The terms and provisions of Section 9(b) and Section 9(c) (except for the
Company’s right to repurchase Shares still subject to a risk of forfeiture upon a Termination Event) shall terminate upon the closing of the Company’s Initial Public Offering or upon consummation of any Sale Event, in either case as a
result of which Shares are registered under Section 12 of the Exchange Act and publicly-traded on any national security exchange. 

  
 16 

	SECTION 10.	 TAX WITHHOLDING 

(a)    Payment by Grantee. Each grantee shall, no later than the date as of which the value of an Award or of any
Shares or other amounts received thereunder first becomes includable in the gross income of the grantee for income tax purposes, pay to the Company, or make arrangements satisfactory to the Committee regarding payment of, any Federal, state, or
local taxes of any kind required by law to be withheld by the Company with respect to such income. The Company and any Subsidiary shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise
due to the grantee. The Company’s obligation to deliver stock certificates (or evidence of book entry) to any grantee is subject to and conditioned on any such tax withholding obligations being satisfied by the grantee. 

(b)    Payment in Stock. The Company’s minimum required tax withholding obligation may be satisfied, in whole
or in part, by the Company withholding from Shares to be issued pursuant to an Award a number of Shares having an aggregate Fair Market Value (as of the date the withholding is effected) that would satisfy the minimum withholding amount due. 

 

	SECTION 11.	 SECTION 409A AWARDS. 

To the extent that any Award is determined to constitute “nonqualified deferred compensation” within the meaning of Section 409A
(a “409A Award”), the Award shall be subject to such additional rules and requirements as may be specified by the Committee from time to time. In this regard, if any amount under a 409A Award is payable upon a “separation from
service” (within the meaning of Section 409A) to a grantee who is considered a “specified employee” (within the meaning of Section 409A), then no such payment shall be made prior to the date that is the earlier of
(i) six months and one day after the grantee’s separation from service, or (ii) the grantee’s death, but only to the extent such delay is necessary to prevent such payment from being subject to interest, penalties and/or
additional tax imposed pursuant to Section 409A. The Company makes no representation or warranty and shall have no liability to any grantee under the Plan or any other Person with respect to any penalties or taxes under Section 409A that
are, or may be, imposed with respect to any Award. 
  

	SECTION 12.	 AMENDMENTS AND TERMINATION 

The Board may, at any time, amend or discontinue the Plan and the Committee may, at any time, amend or cancel any outstanding Award for the
purpose of satisfying changes in law or for any other lawful purpose, but no such action shall adversely affect rights under any outstanding Award without the consent of the holder of the Award. The Committee may exercise its discretion to reduce
the exercise price of outstanding Stock Options or effect repricing through cancellation of outstanding Stock Options and by granting such holders new Awards in replacement of the cancelled Stock Options. To the extent determined by the Committee to
be required either by the Code to ensure that Incentive Stock Options granted under the Plan are qualified under Section 422 of the Code or otherwise, Plan amendments shall be subject to approval by the Company stockholders entitled to vote at
a meeting of stockholders. Nothing in this Section 12 shall limit the Board’s or Committee’s authority to take any action permitted pursuant to Section 3(c). The Board reserves the right to amend the Plan and/or the terms of any
outstanding Stock Options to the extent reasonably necessary to comply with the requirements of the exemption pursuant to paragraph (f)(4) of Rule 12h-1 of the Exchange Act. 

  
 17 

	SECTION 13.	 STATUS OF PLAN 

With respect to the portion of any Award that has not been exercised and any payments in cash, Stock or other consideration not received by a
grantee, a grantee shall have no rights greater than those of a general creditor of the Company unless the Committee shall otherwise expressly so determine in connection with any Award. 

 

	SECTION 14.	 GENERAL PROVISIONS 

(a)    No Distribution; Compliance with Legal Requirements. The Committee may require each person acquiring Shares
pursuant to an Award to represent to and agree with the Company in writing that such person is acquiring the Shares without a view to distribution thereof. No Shares shall be issued pursuant to an Award until all applicable securities law and other
legal and stock exchange or similar requirements have been satisfied. The Committee may require the placing of such stop-orders and restrictive legends on certificates for Stock and Awards as it deems appropriate. 

(b)    Delivery of Stock Certificates. Stock certificates to grantees under the Plan shall be deemed delivered for
all purposes when the Company or a stock transfer agent of the Company shall have mailed such certificates in the United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company; provided that stock
certificates to be held in escrow pursuant to Section 9 of the Plan shall be deemed delivered when the Company shall have recorded the issuance in its records. Uncertificated Stock shall be deemed delivered for all purposes when the Company or
a stock transfer agent of the Company shall have given to the grantee by electronic mail (with proof of receipt) or by United States mail, addressed to the grantee, at the grantee’s last known address on file with the Company, notice of
issuance and recorded the issuance in its records (which may include electronic “book entry” records). 

(c)    No Employment Rights. The adoption of the Plan and the grant of Awards do not confer upon any Person
any right to continued employment or Service Relationship with the Company or any Subsidiary. 
 (d)    Trading
Policy Restrictions. Option exercises and other Awards under the Plan shall be subject to the Company’s insider trading policy-related restrictions, terms and conditions as may be established by the Committee, or in accordance with policies
set by the Committee, from time to time. 
 (e)    Designation of Beneficiary. Each grantee to whom an Award has
been made under the Plan may designate a beneficiary or beneficiaries to exercise any Award on or after the grantee’s death or receive any payment under any Award payable on or after the grantee’s death. Any such designation shall be on a
form provided for that purpose by the Committee and shall not be effective until received by the Committee. If no beneficiary has been designated by a deceased grantee, or if the designated beneficiaries have predeceased the grantee, the beneficiary
shall be the grantee’s estate. 

  
 18 

 (f)    Legend. Any certificate(s) representing the Shares shall
carry substantially the following legend (and with respect to uncertificated Stock, the book entries evidencing such shares shall contain the following notation): 

The transferability of this certificate and the shares of stock represented hereby are subject to the restrictions, terms and conditions
(including repurchase and restrictions against transfers) contained in the Amplitude, Inc. 2014 Stock Option and Grant Plan and any agreements entered into thereunder by and between the company and the holder of this certificate (a copy of which is
available at the offices of the company for examination). 
 (g)    Information to Holders of Options. In the
event the Company is relying on the exemption from the registration requirements of Section 12(g) of the Exchange Act contained in paragraph (f)(1) of Rule 12h-1 of the Exchange Act, the Company shall
provide the information described in Rule 701(e)(3), (4) and (5) of the Securities Act to all holders of Options in accordance with the requirements thereunder. The foregoing notwithstanding, the Company shall not be required to provide such
information unless the optionholder has agreed in writing, on a form prescribed by the Company, to keep such information confidential. 
  

	SECTION 15.	 EFFECTIVE DATE OF PLAN 

The Plan shall become effective upon adoption by the Board and shall be approved by stockholders in accordance with applicable state law and
the Company’s articles of incorporation and bylaws within 12 months thereafter. If the stockholders fail to approve the Plan within 12 months after its adoption by the Board of Directors, then any Awards granted or sold under the Plan shall be
rescinded and no additional grants or sales shall thereafter be made under the Plan. Subject to such approval by stockholders and to the requirement that no Shares may be issued hereunder prior to such approval, Stock Options and other Awards may be
granted hereunder on and after adoption of the Plan by the Board. No grants of Stock Options and other Awards may be made hereunder after the tenth anniversary of the date the Plan is adopted by the Board or the date the Plan is approved by the
Company’s stockholders, whichever is earlier. 
  

	SECTION 16.	 GOVERNING LAW 

This Plan, all Awards and any controversy arising out of or relating to this Plan and all Awards shall be governed by and construed in
accordance with the General Corporation Law of the State of Delaware as to matters within the scope thereof, and as to all other matters shall be governed by and construed in accordance with the internal laws of the State of California, without
regard to conflict of law principles that would result in the application of any law other than the law of the State of California.
