Registration Rights 

2.1 Requested Registration. 

(a) Request for Registration. Subject to the conditions set forth in this Section 2.1, if the Company shall receive from
Initiating Holders a written request signed by such Initiating Holders that the Company effect any registration with respect to all or a part of the Registerable Securities (such request shall state the number of shares of Registerable Securities to
be disposed of by such Initiating Holders), the Company will: 
 (i) promptly give written notice of the proposed registration to all other
Holders; and 

  
 -4- 

 (ii) as soon as practicable, file and use its commercially reasonable efforts to effect such
registration (including, without limitation, filing post-effective amendments, appropriate qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the
sale and distribution of all or such portion of such Registerable Securities as are specified in such request, together with all or such portion of the Registerable Securities of any Holder or Holders joining in such request as are specified in a
written request received by the Company within twenty (20) days after such written notice from the Company is mailed or delivered. 

(b) Limitations on Requested Registration. The Company shall not be obligated to effect, or to take any action to effect, any such
registration pursuant to this Section 2.1: 
 (i) Prior to the earlier of (A) the five (5) year anniversary of the date of
this Agreement or (B) one hundred and eighty (180) days following the effective date of the first registration statement filed by the Company covering an underwritten offering of any of its securities to the general public (or the
subsequent date on which all market stand-off agreements applicable to the offering have terminated); 
 (ii) If the Initiating Holders,
together with the holders of any Other Shares entitled to inclusion in such registration statement, propose to sell Registerable Securities and such Other Shares (if any) the aggregate proceeds of which (after deduction for underwriter’s
discounts and expenses related to the issuance) are less than $30,000,000; 
 (iii) In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in effecting such registration, qualification, or compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities
Act; 
 (iv) After the Company has initiated two (2) such registrations pursuant to this Section 2.1 (counting for these purposes
only (x) registrations which have been declared or ordered effective and pursuant to which securities have been sold, and (y) Withdrawn Registrations); 

(v) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of,
and ending on a date one hundred eighty (180) days after the effective date of, a Company-initiated registration (or ending on the subsequent date on which all market stand-off agreements applicable to the offering have terminated);
provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; 

(vi) If the Initiating Holders propose to dispose of shares of Registerable Securities which may be immediately registered on Form S-3
pursuant to a request made under Section 2.3 hereof; 
 (vii) If the Initiating Holders do not request that such offering be firmly
underwritten by underwriters selected by the Initiating Holders (subject to the consent of the Company); and 
 (viii) If the Company and
the Initiating Holders are unable to obtain the commitment of the underwriter described in clause (b)(vii) above to firmly underwrite the offer. 

  
 -5- 

 (c) Deferral. If (i) in the good faith judgment of the Board of Directors of the
Company, the filing of a registration statement covering the Registerable Securities would be materially detrimental to the Company and the Board of Directors of the Company concludes, as a result, that it is in the best interests of the Company to
defer the filing of such registration statement at such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be materially detrimental to the Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in
addition to the limitations set forth in Section 2.1(b)(v) above) 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, and, provided
further, that the Company shall not defer its obligation in this manner more than two (2) times in any twelve-month period. 
 (d)
Other Shares. The registration statement filed pursuant to the request of the Initiating Holders may, subject to the provisions of Section 2.1(e), include Other Shares, and may include securities of the Company being sold for the account
of the Company. 
 (e) Underwriting. The right of any Holder to include all or any portion of its Registerable Securities in a
registration pursuant to this Section 2.1 shall be conditioned upon such Holder’s participation in an underwriting and the inclusion of such Holder’s Registerable Securities to the extent provided herein. If the Company shall request
inclusion in any registration pursuant to Section 2.1 of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders shall, on behalf of all
Holders, offer to include such securities in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other
securities of the Company and their acceptance of the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders and other persons proposing to distribute their securities through
such underwriting) enter into an underwriting agreement in customary form with the representative(s) of the underwriter or underwriters selected for such underwriting by the Company, which underwriters are reasonably acceptable to a
majority-in-interest of the Initiating Holders. 
 Notwithstanding any other provision of this Section 2.1, if the underwriters advise
the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, the number of Registerable Securities and Other Shares that may be so included shall be allocated as follows: (i) first,
among all Holders requesting to include Registerable Securities in such registration statement based on the pro rata percentage of Registerable Securities held by such Holders, assuming conversion; and (ii) second, to the Company, which the
Company may allocate, at its discretion, for its own account, or for the account of other holders or employees of the Company. 
 If a
person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Company, the underwriter or the Initiating Holders.
The securities so excluded shall also be withdrawn from registration. Any Registerable Securities or other securities excluded or withdrawn from such underwriting shall also be withdrawn from such registration. If shares are so withdrawn from the
registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to this Section 2.1(e), then the Company shall then offer to all Holders and Other Selling
Stockholders who have retained rights to include securities in the registration the right to include additional Registerable Securities or Other Shares in the registration in an aggregate amount equal to the number of shares so withdrawn, with such
shares to be allocated among such Holders and Other Selling Stockholders requesting additional inclusion, as set forth above. 

  
 -6- 

 2.2 Company Registration. 

(a) Company Registration. If the Company shall determine to register any of its securities either for its own account or the account of
a security holder or holders, other than a registration pursuant to Sections 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a registration relating to a
corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will: 

(i) promptly give written notice of the proposed registration to all Holders; and 

(ii) use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other
compliance), except as set forth in Section 2.2(b) below, and in any underwriting involved therein, all of such Registerable Securities as are specified in a written request or requests made by any Holder or Holders received by the Company
within fifteen (15) days after such written notice from the Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registerable Securities. 

(b) Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an underwriting,
the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s
participation in such underwriting and the inclusion of such Holder’s Registerable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with
the Company and the Other Selling Stockholders distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative(s) of the underwriter or underwriters selected by the Company.

 (A) Notwithstanding any other provision of this Section 2.2, if the underwriters advise the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the underwriters may (subject to the limitations set forth below) limit the number of Registerable Securities to be included in the registration and underwriting. The Company
shall so advise all holders of securities requesting registration, and the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for
securities being sold for its own account, and (ii) second, to the Holders requesting to include Registerable Securities in such registration statement based on the pro rata percentage of Registerable Securities held by such Holders, assuming
conversion. Notwithstanding the foregoing, no such reduction shall reduce the value of the Registerable Securities of the Holders included in such registration below twenty five percent (25%) of the total value of securities included in such
registration, unless such offering is the Company’s Initial Public Offering and such registration does not include shares of any other selling stockholders (excluding shares registered for the account of the Company), in which event any or all
of the Registerable Securities of the Holders may be excluded. 
 If a person who has requested inclusion in such registration as provided
above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice from the Company or the underwriter. The Registerable Securities or other securities so excluded shall also be withdrawn from
such registration. Any Registerable Securities or other securities excluded or withdrawn from such underwriting shall be withdrawn from such registration. 

  
 -7- 

 (c) Right to Terminate Registration. The Company shall have the right to terminate or
withdraw any registration initiated by it under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration. 

2.3 Registration on Form S-3.

(a) Request for Form S-3 Registration. After its Initial Public Offering, the Company shall use
its commercially reasonable efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form S-3, in addition to the rights contained in the foregoing provisions of
this Section 2 and subject to the conditions set forth in this Section 2.3, if the Company shall receive from a Holder or Holders of Registerable Securities a written request that the Company effect any registration on Form S-3 or any similar short form registration statement with respect to all or part of the Registerable Securities (such request shall state the number of shares of Registerable Securities to be disposed of and the
intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect to such Registerable Securities as required by Sections 2.1(a)(i) and (ii). 

(b) Limitations on Form S-3 Registration. The Company shall not be obligated to effect, or take
any action to effect, any such registration pursuant to this Section 2.3: 
 (i) In the circumstances described in either
Sections 2.1(b)(iii) or 2.1(b)(v); 
 (ii) If the Holders, together with the holders of any other securities of the Company entitled
to inclusion in such registration, propose to sell Registerable Securities and such other securities (if any) on Form S-3 at an aggregate price to the public of less than $3,000,000; or 

(iii) If, in a given twelve-month period, the Company has effected two (2) such registrations in such period. 

(c) Deferral. The provisions of Section 2.1(c) shall apply to any registration pursuant to this Section 2.3. 

(d) Underwriting. If the Holders of Registerable Securities requesting registration under this Section 2.3 intend to distribute
the Registerable Securities covered by their request by means of an underwriting, the provisions of Section 2.1(e) shall apply to such registration. Notwithstanding anything contained herein to the contrary, registrations effected pursuant to
this Section 2.3 shall not be counted as requests for registration or registrations effected pursuant to Section 2.1. 
 2.4
Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 hereof shall be borne by the Company; provided, however, that the Company shall not be
required to pay for any expenses of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the request of the Holders of a majority of the Registerable Securities to be
registered or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set forth in Sections 2.1 and 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata
among each other based on the number of Registerable Securities requested to be so registered), unless the Holders of a majority of the Registerable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1;
provided, however, in the event that a withdrawal by the Holders is based upon material adverse information relating to the 

  
 -8- 

 
Company that is different from the information known or available (upon request from the Company or otherwise) to the Holders requesting registration at the time of their request for registration
under Section 2.1, such registration shall not be treated as a counted registration for purposes of Section 2.1 hereof, even though the Holders do not bear the Registration Expenses for such registration. All Selling Expenses relating to
securities registered on behalf of the Holders shall be borne by the holders of securities included in such registration pro rata among each other on the basis of the number of Registerable Securities so registered. 

2.5 Registration Procedures. In the case of each registration effected by the Company pursuant to Section 2, the Company will
keep each Holder advised in writing as to the initiation of each registration and as to the completion thereof. At its expense, the Company will use its commercially reasonable efforts to: 

(a) Keep such registration effective for a period of ending on the earlier of the date which is sixty (60) days from the effective date
of the registration statement or such time as the Holder or Holders have completed the distribution described in the registration statement relating thereto; 

(b) To the extent the Company is a well-known seasoned issuer (as defined in Rule 405 under the Securities Act) (a “WKSI”) at
the time any request for registration is submitted to the Company in accordance with Section 2.3, (i) if so requested, file an automatic shelf registration statement (as defined in Rule 405 under the Securities Act) (an “automatic shelf
registration statement”) to effect such registration, and (ii) remain a WKSI (and not become an ineligible issuer (as defined in Rule 405 under the Securities Act)) during the period during which such automatic shelf registration
statement is required to remain effective in accordance with this Agreement; 
 (c) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by
such registration statement for the period set forth in subsection (a) above; 
 (d) Furnish such number of prospectuses, including any
preliminary prospectuses, and other documents incident thereto, including any amendment of or supplement to the prospectus, as a Holder from time to time may reasonably request; 

(e) Use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities
or Blue Sky laws of such jurisdiction 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; 
 (f) Notify each seller of Registerable Securities covered by such registration
statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an
untrue statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing, and following such notification
promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include
an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing;

 2.6 Indemnification.

(a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, each of its officers, directors and partners,
legal counsel and accountants, Affiliates, and each person controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this
Section 2, and each underwriter, if any, and each person who controls within the meaning of Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages and liabilities (or actions, proceedings or
settlements in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or other document (including any
related registration statement, notification or the like) incident to any such registration, qualification or compliance, including any registration statement, any prospectus included in the registration statement, any issuer free writing prospectus
(as defined in Rule 433 of the Securities Act), any issuer information (as defined in Rule 433 of the Securities Act) filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any other document incident to any
such registration, qualification or compliance prepared by or on behalf of the Company or used or referred to by the Company, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, or (iii) any violation (or alleged violation) by the Company of the Securities Act, any state securities laws or any rule or regulation thereunder applicable to the Company and relating to action or
inaction required of the Company in connection with any offering covered by such registration, qualification or compliance, and the Company will reimburse each such Holder, each of its officers, directors, partners, legal counsel and accountants,
Affiliates, and each person controlling such Holder, each such underwriter and each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any
such claim, loss, damage, liability or action; provided that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or action arises directly out of or is based directly on any untrue
statement or omission provided in written information furnished to the Company by such Holder, any of such Holder’s officers, directors, partners, legal counsel or accountants, any person controlling such Holder, such underwriter or any person
who controls any such underwriter, and stated to be specifically for use therein; and provided, further that, the indemnity agreement contained in this Section 2.6(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, conditioned or delayed). 

(b) To the extent permitted by law, each Holder will, if Registerable Securities held by such Holder are included in the securities as to
which such registration, qualification or compliance is being effected, indemnify and hold harmless the Company, each of its directors, officers, partners, legal counsel and accountants and each underwriter, if any, of the Company’s securities
covered by such a registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, each other such Holder, and each of their officers, directors and partners, Affiliates
and each person controlling each other such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact
contained or incorporated by reference in any prospectus, offering circular or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification or compliance, or (ii) any
omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and such Holders, directors, officers, partners, Affiliates, legal counsel and
accountants, persons, underwriters, Affiliates, or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent,
but only to the extent, 

  
 -11- 

 
that such untrue statement or omission is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder and stated to be specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in settlement of any such claims, losses, damages
or liabilities or actions in respect thereof if such settlement is effected without the consent of such Holder which consent shall not be unreasonably withheld; and provided that in no event shall any indemnity under this Section 2.6
exceed the gross proceeds from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder. 

(c) Each party entitled to indemnification under this Section 2.6 (the “Indemnified Party”) shall give notice to the
party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the
defense of such claim or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the Indemnified Party
(whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; and provided further that the failure of any Indemnified Party to give notice as provided herein
shall not relieve the Indemnifying Party of its obligations under this Section 2.6, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each
Indemnified Party, consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to
such claim or litigation. Each Indemnified Party shall furnish such information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of
such claim and litigation resulting therefrom. 
 (d) If the indemnification provided for in this Section 2.6 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 of the
Indemnified Party on the other in connection with the statements or omissions that resulted in such loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and
of the Indemnified Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or
by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and opportunity to correct or prevent such statement or omission. No person or entity will be required under this Section 2.6(d) to contribute any
amount in excess of the gross proceeds from the offering received by such person or entity, except in the case of fraud or willful misconduct by such person or entity. No person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation. 

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

(a) The holder of each certificate representing Registerable Securities by acceptance thereof agrees to comply in all respects with the
provisions of this Section 2.8. Each Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of Restricted Securities, or any beneficial interest therein, unless and until (x) the

furnished the Company with a detailed description of the manner and circumstances of the proposed disposition, and, if requested by the Company, such Holder shall have furnished the Company, at its expense, with (i) an opinion of counsel,
reasonably satisfactory to the Company, to the effect that such disposition will not require registration of such Restricted Securities under the Securities Act or (ii) a “no action” letter from the Commission to the effect that the
transfer of such securities without registration will not result in a recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such
Restricted Securities in accordance with the terms of the notice delivered by the Holder to the Company. 
 (b) Permitted transfers include
(i) a transfer not involving a change in beneficial ownership; (ii) transactions involving the distribution without consideration of Restricted Securities by any Holder to (x) a parent, subsidiary or other Affiliate of a Holder that

retired partners, retired members or other equity owners, or (z) a venture capital fund or other private investment fund that is controlled by or under common control with one or more general partners or managing members of, or shares the same
management company with, such Holder; or (iii) transfers in compliance with Rule 144(b), as long as the Company is furnished with satisfactory evidence of compliance with such Rule; provided, in each case, that the Holder thereof
shall give written notice to the Company of such Holder’s intention to effect such disposition and shall have furnished the Company with a detailed description of the manner and circumstances of the proposed disposition. 

(c) Each certificate representing Registerable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped or
otherwise imprinted with a legend substantially similar to the following (in addition to any legend required under applicable state securities laws): 

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR

  
 -13- 

 
UNDER THE SECURITIES LAWS OF CERTAIN STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE
SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES
WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. 
 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO (1) RESTRICTIONS ON
TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A VOTING AGREEMENT AMONG THE COMPANY AND THE ORIGINAL

 The Holders consent to the Company
making a notation on its records and giving instructions to any transfer agent of the Restricted Securities in order to implement the restrictions on transfer established in this Section 2.8. 

(d) The first legend referring to federal and state securities laws identified in Section 2.8(c) hereof stamped on a certificate
evidencing the Restricted Securities and the stock transfer instructions and record notations with respect to such Restricted Securities shall be removed and the Company shall issue a certificate without such legend to the holder of such Restricted
Securities if (i) such securities are registered under the Securities Act, (ii) such holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a public sale or transfer of such
securities may be made without registration under the Securities Act, or (iii) such holder provides the Company with reasonable assurances, which shall, at the option of the Company, include an opinion of counsel satisfactory to the Company,
that such securities can be sold pursuant to Section (b) of Rule 144 under the Securities Act. 
 (e) Each Investor agrees not to
make any sale, assignment, transfer, pledge or other disposition of any securities of the Company, or any beneficial interest therein, to any person other than the Company unless and until the proposed transferee confirms to the reasonable
satisfaction of the Company that neither the proposed transferee nor any of its directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members nor any
person that would be deemed a beneficial owner of those securities (in accordance with Rule 506(d) of the Securities Act) is subject to any Bad Actor Disqualification, except as set forth in Rule 506(d)(2)(ii) or (iii) or (d)(3) under

and regulations of the Commission that may permit the sale of the Restricted Securities to the public without registration, the Company agrees to use its commercially reasonable efforts to: 

(a) Make and keep public information regarding the Company available as those terms are understood and defined in Rule 144 under the
Securities Act, at all times from and after ninety (90) days following the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public; 

(b) File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the
Exchange Act at any time after it has become subject to such reporting requirements; and

of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the
most recent annual or quarterly report of the Company, and such other reports and documents so filed as a Holder may reasonably request in availing itself of any rule or regulation of the Commission allowing a Holder to sell any such securities
without registration. 
 2.10 Market Stand-Off Agreement. Each Holder shall not sell or otherwise transfer, make any short sale of,
grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Common Stock (or other securities) of the Company held by such Holder (other than those included in the
registration) during the one hundred and eighty (180) day period following the effective date of the registration statement for the Company’s Initial Public Offering filed under the Securities Act (or such other period as may be requested
by the Company or an underwriter to accommodate regulatory restrictions on (i) the publication or other distribution of research reports and (ii) analyst recommendations and opinions, including, but not limited to, the restrictions
contained in NASD Rule 2711(f)(4) or NYSE Rule 472(f)(4), or any successor provisions or amendments thereto), provided that all officers and directors of the Company and all holders of at least one percent (1%) of the
Company’s voting securities are bound by and have entered into similar agreements. The obligations described in this Section 2.10 shall not apply to a registration relating solely to employee benefit plans on Form S-l or Form S-8 or
similar forms that may be promulgated in the future, or a registration relating solely to a transaction on Form S-4 or similar forms that may be promulgated in the future. The Company may impose stop-transfer instructions and may stamp each such
certificate with the second legend set forth in Section 2.8(c) hereof with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one hundred and eighty (180) day (or other)

2.11 Delay of Registration. No Holder shall have any right to take any action to restrain, enjoin, or otherwise delay any registration
as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 
 2.12
Transfer or Assignment of Registration Rights. The rights to cause the Company to register securities granted to a Holder by the Company under this Section 2 may be transferred or assigned by a Holder to any transferee or assignee of
Registerable Securities; provided that (i) such transfer or assignment of Registerable Securities is effected in accordance with the terms of Section 2.8 hereof, the Right of First Refusal and Co-Sale Agreement, and applicable
securities laws, (ii) the Company is given written notice prior to said transfer or assignment, stating the name and address of the transferee or assignee and identifying the securities with respect to which such registration rights are

transferee or assignee of such rights assumes in writing the obligations of such Holder under this Agreement, including without limitation the obligations set forth in Section 2.10;
provided further that the right to request a registration pursuant to Section 2.1 may not be transferred unless the transferee or assignee holds at least 500,000 shares of Registerable Securities (as presently constituted and subject to
subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like). 
 2.13 Limitations on Subsequent
Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of Holders holding a majority of the Registerable Securities, enter into any agreement with any holder or prospective holder
of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are senior to the registration rights granted to the Holders hereunder. 

2.14 Termination of Registration Rights. The right of any Holder to request registration or inclusion in any registration pursuant to
Sections 2.1, 2.2 or 2.3 shall terminate on the earlier of (i) such date, on or after the closing of the Company’s first registered public offering of Common Stock, on which all shares of Registerable Securities held or entitled to be held
upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90) day period and (ii) five (5) years after the closing of the Company’s Initial Public Offering. 

Section 3 

Information Covenants of the Company 

The Company hereby covenants and agrees, as follows: 

3.1 Basic Financial Information and Inspection Rights. 

(a) Basic Financial Information. The Company will furnish the following reports to each Holder who owns at least 5,000,000 Shares
and/or shares of Conversion Stock (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits, and the like) (each such Holder, a “Significant Holder”): 

(i) As soon as practicable after the end of each fiscal year of the Company, and in any event within one hundred eighty (180) days after
the end of each fiscal year of the Company, an audited consolidated balance sheet of the Company and its subsidiaries, if any, as at the end of such fiscal year, and audited consolidated statements of income and cash flows of the Company and its

following the date of this Agreement, and in any event within forty-five (45) days after the end of the first, second, and third quarterly accounting periods in each fiscal year of the Company, an unaudited consolidated balance sheet of the
Company and its subsidiaries, if any, as of the end of each such quarterly period, and unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S.
generally accepted accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments; 

  
 -16- 

 (iii) As soon as practicable after the end of each month following the date of this Agreement,
and in any event within thirty (30) days after the end of each month, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of such monthly period, and unaudited consolidated statements of income and
cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting from normal year-end audit adjustments; 

(iv) An operating plan prior to the beginning of each fiscal year following the date of this Agreement; and 

(v) Copies of all other reports and information that are delivered to all other stockholders of the Company. 

3.2 Inspection Rights. The Company will afford to each Significant Holder and to such Significant Holder’s accountants and
counsel, reasonable access during normal business hours to all of the Company’s respective properties, books and records. Each such Significant Holder shall have such other access to management and information as is necessary for it to comply
with applicable laws and regulations and reporting obligations. Pursuant to any requests under this Section 3.2, the Company shall not be required to disclose details of contracts with or work performed for specific customers and other business
partners where to do so would violate confidentiality obligations to those parties. Significant Holders may exercise their rights under this Section 3.2 only for purposes reasonably related to their interests under the Agreements (as defined in
the Purchase Agreement). The rights granted pursuant to this Section 3.2 may not be assigned or otherwise conveyed by the Holders or by any subsequent transferee of any such rights without the prior written consent of the Company except to an
Affiliate or as authorized in this Section 3.2. 
 3.3 Confidentiality. Anything in this Agreement to the contrary
notwithstanding, no Holder by reason of this Agreement shall have access to any trade secrets or similar confidential information of the Company. The Company shall not be required to comply with any information rights of Section 3 in respect of
any Holder whom the Company reasonably determines to be a competitor or an officer, employee, director or holder of more than ten percent (10%) of a competitor. Each Holder acknowledges that the information received by them pursuant to this
Agreement may be confidential and for its use only, and it will not use such confidential information or reproduce, disclose or disseminate such information to any other person (other than its employees, Affiliates or agents having a need to know
the contents of such information, and its attorneys), except in connection with the exercise of rights under this Agreement, unless the Company has made such information available to the public generally or such Holder is required to disclose such
information by a governmental authority. 
 3.4 FCPA. 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, representatives or agents to) promise, authorize or make any payment to, or otherwise contribute any item of value to, directly or indirectly, to
any third party, including any foreign official (as such term is defined in the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”)), in each case, in violation of the FCPA, 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, representatives or agents in violation of the FCPA, 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) maintain systems of internal controls (including, but 

  
 -17- 

 
not limited to, accounting systems, purchasing systems and billing systems) to ensure compliance with the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law.
Upon request, the Company agrees to provide responsive information and/or certifications concerning its compliance with applicable anti-corruption laws. The Company shall promptly notify each Investor if the Company becomes aware of any allegation
or investigation made or initiated by any government, voluntary disclosure, prosecution or other enforcement action related to the FCPA or any other anti-corruption law. The Company shall require any direct or indirect subsidiary or entity
controlled by it, whether now in existence or formed in the future, to comply with the FCPA. 
 3.5 Termination of Covenants. The
covenants set forth in this Section 3 shall terminate and be of no further force and effect upon a Qualified Public Offering or a Liquidation Event. 

Section 4 
 Right
of First Refusal 
 4.1 Right of First Refusal to Significant Holders. The Company hereby grants to each Significant Holder,
the right of first refusal to purchase its pro rata share of New Securities (as defined Section 4.1(a)) which the Company may, from time to time, propose to sell and issue after the date of this Agreement (“ROFR”). A
Significant Holder’s pro rata share for purposes of this right of first refusal is equal to the ratio of (a) the number of shares of Common Stock owned by such Significant Holder immediately prior to the issuance of New Securities
(assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly, into Common Stock held by said Significant Holder) to (b) the total number of shares of Common
Stock outstanding immediately prior to the issuance of New Securities (assuming full conversion of the Shares and exercise of all outstanding convertible securities, rights, options and warrants, directly or indirectly). This right of first refusal
shall be subject to the following provisions: 
 (a) “New Securities” shall mean any capital stock (including Common Stock
and/or Preferred Stock) of the Company whether now authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible
into capital stock; provided that the term “New Securities” does not include: 
 (i) the Shares and
the Conversion Stock; 
 (ii) the Excluded Issuances (as defined in the Company’s Certificate of Incorporation as in effect on the
date of this Agreement); and 
 (iii) any right, option or warrant to acquire any security convertible into the Excluded Issuances. 

(b) If the Company proposes to undertake an issuance of New Securities, it shall give each Significant Holder written notice (the
“ROFR Notice”) of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Significant Holder shall have twenty (20) days after any such
ROFR Notice is mailed or delivered (the “Election Period”) to elect to purchase such Holder’s pro rata share of such New Securities for the price and upon the terms specified in the ROFR Notice by giving written notice to the
Company, in substantially the form attached hereto as Schedule 1, and stating therein the quantity of New Securities to be purchased. 

  
 -18- 

 (c) If the New Securities are being issued at a price per share less than the then Conversion
Price (as defined in the Company’s certificate of incorporation) of the Series D Preferred Stock, and one or more Significant Holders does not exercise its ROFR in full within the Election Period (such unexercised portion of the Significant
Holders’ ROFR, the “Unexercised ROFR Shares”), TPG Zookeeper (A), LP and TPG Zookeeper (B), LP (together, “TPG”) shall have the right to purchase the Unexercised ROFR Shares (the “TPG Over-Allotment
Right”) for the price and upon the terms specified in the ROFR Notice. Promptly after the expiration of the Election Period, the Company shall notify TPG of the number of Unexercised ROFR Shares. TPG shall have ten (10) days after any
such ROFR Notice is mailed or delivered (the “TPG Over-Allotment Period”) to elect to purchase all or any portion of the Unexercised ROFR Shares for the price and upon the terms specified in the ROFR Notice by giving written notice
to the Company, and stating therein the quantity of Unexercised ROFR Shares to be purchased. 
 (d) If a Significant Holder fails to elect
to exercise fully its ROFR within the Election Period and, if applicable, TPG subsequently fails to elect to exercise fully its TPG Over-Allotment Right within the TPG Over-Allotment Period, the Company shall have ninety (90) days thereafter to
sell or enter into an agreement (pursuant to which the sale of New Securities covered thereby shall be closed, if at all, within ninety (90) days from the date of said agreement) to sell that portion of the New Securities with respect to which
the Significant Holders’ ROFR and, if applicable, the TPG Over-allotment Right, was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the ROFR Notice. In the event the Company has not sold
such new securities within such ninety (90) day period, the Company shall not thereafter issue or sell any New Securities, without first again offering such securities to the Significant Holders in the manner provided in this Section 4.1.

 (e) The right of first refusal granted under this Agreement shall not be applicable to the Company’s Initial Public Offering and
shall terminate upon a Qualified Public Offering or a Liquidation Event. 
 (f) A Holder will not have a right of first refusal to purchase
a pro rata share of New Securities in accordance with this Section 4 and will not be a Significant Holder for purposes of the right of first refusal granted under this Section 4 if, and for so long as, the Holder, any of its
directors, executive officers, other officers that may serve as a director or officer of any company in which it invests, general partners or managing members or any person that would be deemed a beneficial owner of the securities of the Company

Section 5 

Miscellaneous 
 5.1
Amendment. Neither this Agreement nor any term hereof may be amended, terminated, waived or discharged other than by a written instrument referencing this Agreement and signed by (i) the Company and (ii) Holders holding a majority
of the Registerable Securities (excluding any of such shares that have been sold to the public or pursuant to Rule 144); provided, however, that if such amendment, termination, waiver or discharge would adversely affect the rights, or add to
the obligations, of any existing series of Preferred Stock (whether or not any other existing series of Preferred Stock is being treated in a similar manner) or any Holder in a manner differently from other Holders, as the case may be, then such
amendment, termination, waiver or discharge shall require the consent of the Holders holding a majority in interest of such series of Preferred Stock or such Holder, as the case may be, provided however that an amendment that adds another
series of preferred stock with rights and preferences pari passu with the existing Preferred Stock shall not be 

  
 -19- 

 
considered to adversely affect the rights of the existing Preferred Stock or a particular series of Preferred Stock; and provided, further, that Holders purchasing shares of Series D
Preferred Stock in a Closing after the Initial Closing (each as defined in the Purchase Agreement) may become parties to this Agreement by executing a counterpart of this Agreement without any amendment of this Agreement pursuant to this paragraph
or any consent or approval of any other Holder; provided, further, Sections 4, 5.1 and 5.4 may not be amended in a manner that adversely affects EMC Corporation, waived, or terminated without the prior written consent of EMC Corporation;
provided, further, Sections 3.1, 3.2, 4, 5.1 and 5.4 may not be amended in a manner that adversely affects TPG, waived, or terminated without the prior written consent of TPG; provided, further, that any increase in the number of
shares set forth in the definition of “Significant Holder” in Section 3.1(a) and any amendment, termination or waiver of Sections 5.3 or 5.11 shall require the consent of EMC Corporation and TPG; and provided further, that any
amendment of Section 4.1(c) in a manner that adversely affects TPG shall require the consent of TPG. Any amendment, waiver, termination, or discharge effected in accordance with this paragraph shall be binding upon each Holder and each future
holder of all such securities of Holder. Each Holder acknowledges that by the operation of this paragraph and subject to the conditions set forth above, the Holders holding a majority of the Registerable Securities (excluding any of such shares that
have been sold to the public or pursuant to Rule 144) will have the right and power to diminish or eliminate all rights of such Holder under this Agreement; provided, however, that if this Agreement is terminated in accordance with the provisions
hereof, the Company may not enter into another agreement relating to the subject matter of this Agreement containing provisions that would not have been permissible as an amendment or waiver to this Agreement without obtaining the consents that
would have been required by this Section 5.1 had that new agreement been an amendment or waiver of this Agreement. 
 5.2
