have entered into a License Agreement dated as of July 25, 2006 and subsequently amended on January 5, 2009 (collectively the “License Agreement”); 

The Restoration, HSC and Harris each desire to modify the License Agreement to accurately reflect their current business arrangement. 

AMENDMENT 
 NOW,
THEREFORE, in consideration of the mutual promises contained herein and for other consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows: 

1. Modification of License Agreement. Restoration, HSC and Harris each agree to modify the License Agreement as follows: 

Section 4.1 Restoration’s Right of Patent Enforcement in Field of Use. 

Section 4.1 is hereby deleted and replaced with the following: 

“Section 4.1 Restoration’s Right of Patent Enforcement. 

(a) [***], Restoration and its Affiliates (collectively “Restoration” for the remainder of this Section 4.0) shall have the
right but not the obligation to bring suit against third parties who infringe a Licensed Patent [***] in its own name and on its own behalf. In addition, for any Licensed Patent resulting from a patent or patent application that [***] (including but
not limited to [***]), Restoration shall have the right but not the obligation to bring suit against third parties who infringe such Licensed Patent [***] in its own name and on its own behalf. 

(b) Harris and HSC shall have the first right, but not the obligation, to enforce the Licensed Patents against any third party infringing
[***]. Upon learning of such infringement of any Licensed Patent by third parties [***], Harris and/or HSC shall inform Restoration in writing of that fact, and within [***] ([***]) days after learning of such possible infringement shall notify
Restoration of its decision whether to pursue any infringement suit against such third party. In the event that Harris and/or HSC fails or decides not to enforce such Licensed Patent within the above-mentioned [***] ([***]) days, Restoration shall
have the right, but not the obligation to bring suit against third parties who infringe such Licensed Patent [***] in its own name and on its own behalf. 

 (c) Before communicating to any third party about the possible infringement of a Licensed Patent
including serving a complaint filed in any court on such third party alleging infringement of a Licensed Patent per subsections (a) and (b) above, Restoration must first notify HSC and/or Harris, as applicable, in writing. Harris and/or
HSC shall supply Restoration with any evidence (e.g., data, records, samples or the like) available in its possession and control pertaining to the third party infringement, including both enforcement and potential defense of such Licensed Patent.
If so requested, Restoration, HSC and/or Harris agree to enter into a Joint Defense and Prosecution Agreement, the same or substantially similar to that provided in Exhibit B, for the purpose of allowing the respective parties to share confidential
and attorney-client privileged information regarding the possible infringement of one or more Licensed Patents by third parties. 

Section 4.4 Settlement. 

Section 4.4 is hereby deleted and replaced with the following: 

“Section 4.4 Settlement. Restoration agrees to not settle any suit or other enforcement, defense or maintenance action brought by Restoration
against a third party pursuant to Section 4.1 without the prior written consent of HSC and/or Harris, as applicable, [***]. However, for settlement of those Licensed Patents resulting from a patent or patent application that HSC and/or Harris
decides not to continue patent prosecution, appeal or maintenance per Section 6.0 below and for which Restoration decides at its option and sole discretion to continue prosecution, appeal or maintenance (as stated in Section 4.1(a) above),
Restoration is not required to obtain any prior written consent of HSC and/or Harris. HSC and Harris each agrees to not enter into any agreement or make any binding statement [***] that [***] impact on the scope, validity, or enforceability of a
Licensed Patent, without the prior written consent of Restoration, [***]. 
 2. No Further Amendments. Except as expressly set
forth in this Second Amendment to License Agreement, the License Agreement shall remain unmodified and in full force and effect (including any Exhibits thereto). In the event of any conflict, ambiguity or inconsistency between the terms and
provisions of this Second Amendment to License Agreement and the terms and provisions of the License Agreement, the terms and provisions of this Second Amendment to License Agreement shall govern and control. 

3. Counterparts. This Second Amendment to License Agreement may be executed in any number of counterparts, each of which shall be
considered an original and all of which shall constitute one and the same instrument.

 RESTORATION ROBOTICS, INC. 

AMENDED AND RESTATED 

INVESTORS’ RIGHTS AGREEMENT 

This Amended and Restated Investors’ Rights Agreement (this “Agreement”) is made and entered into as of February
7th, 2013 by and among Restoration Robotics, Inc., a Delaware corporation (the “Company”), and the holders of the Company’s Preferred Stock identified on Exhibit A attached hereto (the
“Investors”). Other capitalized terms used in this Agreement have the meanings ascribed to them in Section 4.1. 

Recitals 
 WHEREAS,
the Company proposes to sell shares of the Company’s Series AA Preferred Stock to one or more new investors; 
 WHEREAS, the
Company and certain of the Investors (the “Existing Investors”) are parties to the Amended and Restated Investor Rights Agreement dated August 2, 2011, by and among the Company and the Investors set forth therein (the
“Prior Rights Agreement”); 
 WHEREAS, as a condition to purchasing shares of Series AA Preferred Stock, each
such new investor shall become a party to this Agreement by executing a countersignature page or joinder to the Agreement and becoming a Stockholder hereunder; and 

WHEREAS, the Company and the Investors have mutually agreed to enter into this Agreement. 

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

Section 1 

Restrictions on Transferability of Securities; Registration Rights 

1.1 Restrictions on Transfer 

(a) Each Holder agrees not to make any disposition of all or any portion of the Registrable Securities unless and until (i) there is then
in effect a registration statement under the Securities Act covering such proposed disposition and such disposition is made in accordance with such registration statement or (ii) such Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of the circumstances surrounding the proposed disposition, and if reasonably requested by the Company, such Holder shall have furnished the Company with an opinion of
counsel, reasonably satisfactory to the 

 
Company, that such disposition will be exempt from registration under the Securities Act. Notwithstanding the foregoing, no such registration statement or opinion of counsel shall be necessary
for a transfer without consideration by such Holder: 
 (i) to a fund, partnership, limited liability company or other entity that is
affiliated with such transferring Holder; 
 (ii) to a partner or member (or retired partner or member) of such transferring Holder, or to
the estate of any such partner or member (or retired partner or member); 
 (iii) to such transferring Holder’s spouse, siblings,
lineal descendants or ancestors by gift, will or intestate succession; or 
 (iv) in compliance with Rule 144 (or any successor provision)
of the Securities Act so long as the Company is furnished with satisfactory evidence of compliance with such rule; 
 provided, however,
that, in the case of (i), (ii) or (iii), the transferee is not a competitor of the Company as determined in good faith by the Board of Directors and agrees in writing to be subject to the terms hereof to the same extent as if he or she were an
original Investor hereunder. Each Holder shall cause any proposed purchaser, assignee, transferee or pledgee of any Registrable Securities held by the Holder to take and hold such securities subject to the provisions and upon the conditions of this
Agreement, the Amended and Restated Right of First Refusal and Co-Sale Agreement dated as of August 2, 2011 (the “Right of First Refusal Agreement”), the Amended and Restated
Voting Agreement dated of even date herewith (the “Voting Agreement”) and the applicable purchase agreement pursuant to which such Holder acquired the Registrable Securities. Each Holder consents to the Company’s making
a notation on its records and giving instructions to any transfer agent for its capital stock to implement the restrictions on transfer established in this Agreement, the Right of First Refusal Agreement and Voting Agreement. 

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

THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED (THE “ACT”) AND
MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION
OTHERWISE COMPLIES WITH THE ACT. 

  
 2 

 THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS
FOLLOWING THE EFFECTIVE DATE OF A REGISTRATION STATEMENT OF THE COMPANY FILED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR FOR A LONGER PERIOD NOT TO EXCEED 34 DAYS IF THE ISSUER’S TRANSFER AGENT IS NOTIFIED BY THE ISSUER OR THE
ISSUER’S COUNSEL THAT THIS LOCK-UP PERIOD RESTRICTION HAS BEEN EXTENDED FOR THE PURPOSE OF COMPLYING WITH NASD RULE 2711(F)(4) OR ANY SUCCESSOR PROVISIONS OR AMENDMENTS THERETO, AS SET FORTH IN AN
AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY. SUCH LOCK-UP PERIOD IS BINDING ON TRANSFEREES OF THESE SHARES.

 (c) The Company shall be obligated to reissue unlegended certificates at the request of any Holder thereof if the Holder shall have
obtained (i) an opinion of counsel at such Holder’s expense (which counsel may be counsel to the Company) reasonably acceptable to the Company to the effect that the securities proposed to be disposed of may lawfully be so disposed of
without 
 (d) registration, qualification or legend, and (ii) delivered such securities to the Company or its transfer agent. 

(e) Any legend endorsed on an instrument pursuant to applicable state securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the appropriate blue sky authority authorizing such removal. 

1.2 Requested Registration 

(a) Request for Registration. If the Company shall receive from Initiating Holders at any time not earlier than the first to
occur of (i) one hundred eighty (180) days following the Company’s initial public offering and (ii) July 31, 2016, a written request that the Company effect any registration with respect to such number of shares having an
aggregate offering price of at least $5,000,000, the Company will: 
 (i) within thirty (30) days of the receipt of such written
request give written notice of the proposed registration to all other Holders; and 
 (ii) as soon as practicable, 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 as would permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are specified in such request, together with all or such portion of the Registrable 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. Notwithstanding anything to the contrary contained herein, if

  
 3 

 
the registration requested is to be an underwritten offering and if the underwriters have not limited the number of Registrable Securities to be underwritten, the Company shall be entitled, at
its election, to join in any such registration with respect to securities to be offered by it or any other party. 
 The Company shall not
be obligated to effect, or to take any action to effect, any such registration pursuant to this Section 1.2: 
 (A) 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; 
 (B) After the Company has initiated two (2) such registrations pursuant to this
Section 1.2(a) (counting for these purposes only registrations which have been declared or ordered effective and pursuant to which securities have been sold and registrations which have been withdrawn by the Holders as to which the
Holders have not elected to bear the Registration Expenses pursuant to Section 1.4 hereof and would, absent such election, have been required to bear such expenses); 

(C) During the period starting with the date of filing, and ending on a date one hundred eighty (180) days after the effective date of,
the Company’s initial public offering; 
 (D) If, within thirty (30) days of receipt of any registration request, the Company
furnishes to the Holders a notice of the Company’s intent to file such a registration statement for a Qualified Public Offering within ninety (90) days of such notice; or 

(E) If the Initiating Holders propose to dispose of shares of Registrable Securities which may be immediately registered on Form S-3 pursuant to a request made under Section 1.5 hereof. 
 (b) Subject to the foregoing
clauses, the Company shall file a registration statement covering the Registrable Securities so requested to be registered as soon as practicable after receipt of the request or requests of the Initiating Holders; provided, however,
that if (i) in the good faith judgment of the Board of Directors of the Company, such registration would be 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 within thirty (30) days of receipt of any registration request a certificate signed by an officer of the Company
stating that in the good faith judgment of the Board of Directors of the Company, it would be 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 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 once in any twelve (12) month period. 

  
 4 

 The registration statement filed pursuant to the request of the Initiating Holders may, subject
to the provisions of Sections 1.2(c) and 1.13 hereof, include other securities of the Company, with respect to which registration rights have been granted, and may include securities of the Company being sold for the account of the
Company. 
 (c) Underwriting. 

(i) 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 part of their request and the Company shall include such information in its written notice to the other Holders. The right of any Holder to registration pursuant to Section 1.2 shall be conditioned upon
such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. Subject to the provisions set forth herein, a Holder may elect to include in such
underwriting all or part of the Registrable Securities they hold. 
 (ii) If the Company shall request inclusion in any registration
pursuant to Section 1.2(a) of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 1.2(a), the Initiating Holders shall, on behalf of all Holders,
offer to include such securities in the underwriting and may condition such offer on their acceptance of the further applicable provisions of this Section 1 (including Section 1.12). 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 of the underwriter or underwriters selected for such underwriting by a majority in interest of
the Initiating Holders, which underwriters are reasonably acceptable to the Company. Notwithstanding any other provision of this Section 1.2, if the representative of the underwriters advises the Initiating Holders in writing that marketing
factors require a limitation on the number of shares to be underwritten, the number of shares to be included in the underwriting or registration shall be allocated as set forth in Section 1.13 hereof. 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 Registrable 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 1.2(c), then the Company shall offer to all holders who have retained rights to include securities in the registration the
right to include additional securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among such Holders requesting additional inclusion in accordance with
Section 1.13. 

  
 5 

 1.3 Company Registration 

(a) 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
exercising their respective demand registration rights (other than pursuant to Section 1.2 or 1.5 hereof), other than a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, or
a registration relating to a corporate reorganization or other transaction on Form S-4, or a registration on any registration form that does not permit secondary sales, the Company will: 

(i) within fifteen (15) days prior to the filing of any registration statement pursuant thereto give to each Holder written notice
thereof; 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 1.3(b) below, and in any underwriting involved therein, all the Registrable Securities specified in a written request or requests, made by any Holder and received by the Company
within ten (10) days after the written notice from the Company described in clause (i) above is mailed or delivered by the Company. Such written request may specify all or a part of a Holder’s Registrable Securities. If a Holder
decides not to include all of its Registrable Securities in any registration statement thereafter filed by the Company, such Holder shall nevertheless continue to have the right to include any Registrable Securities in any subsequent registration
statement or registration statements as may be filed by the Company with respect to offerings of its securities, all upon the terms and conditions set forth herein. 

(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 1.3(a)(i). In such event, the right of any Holder to registration pursuant to this Section 1.3 shall be conditioned upon such
Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable 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 holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the
representative of the underwriter or underwriters selected by the Company. 
 Notwithstanding any other provision of this
Section 1.3, if the representative of the underwriters advises the Company in writing that marketing factors require a limitation on the number of shares to be underwritten, the representative may (subject to the limitations set forth
below) exclude all Registrable Securities from, or limit the number of Registrable 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 first to the Company for securities being sold for its own account and thereafter as set forth in Section 1.13;
provided, however, that (i) the underwriter may completely cut back any Registrable Securities in connection with the Company’s initial public offering so long as such registration does not include shares of any other selling
stockholders and 

  
 6 

 
(ii) in connection with any other registration, the underwriter may not cut back the Registrable Securities so that they constitute less than thirty percent (30%) of the shares to be included in
such registration. If any person does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from the Company or the underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. To facilitate the allocation of shares in accordance with the above provisions, the Company or the underwriter(s) may round the number of shares allocated to any Holder to
the nearest 100 shares. 
 If shares are so withdrawn from the registration and if the number of shares of Registrable Securities to be
included in such registration was previously reduced as a result of marketing factors, the Company shall then offer to all persons who have retained the right to include securities in the registration the right to include additional securities in
the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares to be allocated among the persons requesting additional inclusion in accordance with Section 1.13 hereof. 

(c) 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. 

1.4 Expenses of Registration All Registration Expenses incurred in connection with any registration, qualification or compliance
pursuant to Sections 1.2, 1.3, and 1.5 hereof shall be borne by the Company. All Selling Expenses relating to securities so registered shall be borne by the holders of such securities pro rata on the basis of the number
of shares of securities so registered on their behalf, as shall any other expenses in connection with the registration required to be borne by the holders of such securities. The Company shall not, however, be required to pay for expenses of any
registration proceeding begun pursuant to Section 1.2 or Section 1.5, the request of which has been subsequently withdrawn by the Holders unless the withdrawal is based upon material adverse information concerning the Company
of which the Holders were not aware at the time of such request. If the Holders bear the Registration Expenses for any registration proceeding begun pursuant to Section 1.2 or Section 1.5 and subsequently withdrawn by the
Holders registering shares therein, such registration proceeding shall not be counted as a requested registration pursuant to Section 1.2 or Section 1.5 hereof. If the Holders are required to pay the Registration Expenses,
such expenses shall be borne by the holders of securities (including Registrable Securities) requesting such registration in proportion to the number of shares for which registration was requested. If the Company is required to pay the Registration
Expenses of a withdrawn offering as provided above, then the Holders shall not forfeit their rights pursuant to Section 1.2 or Section 1.5 to a demand registration. 

1.5 Registration on Form S-3 

(a) 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 1, each of the Major Holders shall have the right to 

  
 7 

 request registrations on Form S-3 (such requests shall be in writing and
shall state the number of shares of Registrable Securities to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), provided, however, that the Company shall not be obligated to effect any
such registration (i) if the Major 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) on Form S-3 at an aggregate price to the public of less than $l0,000,000, (ii) in the circumstances described in clauses (A) and (C) of Section 1.2(a); (iii) if the Company shall furnish the certification
described in Section 1.2(b) (but subject to the limitations set forth therein), or (iv) if, in a given twelve month period, the Company has effected two (2) such registrations. 

(b) If a request complying with the requirements of Section 1.5(a) hereof is delivered to the Company, the provisions of Sections
1.2(a)(i) and (ii) and Section 1.2(b) hereof shall apply to such registration. If the registration is for an underwritten offering, the provisions of Sections 1.2(c) hereof shall apply to such registration. 

1.6 Registration Procedures In the case of each registration effected by the Company pursuant to Section 1, 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 one hundred twenty (120) days or until the Holder or Holders have completed the
distribution described in the registration statement relating thereto, whichever first occurs; 
 (b) 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; 
 (c) Furnish such number of 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; 
 (d) Use 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) Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed; 

  
 8 

 (f) In connection with any underwritten public offering, the Company will enter into an
underwriting agreement in form reasonably necessary to effect the offer and sale of Common Stock, provided such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder participating in such
underwriting shall also enter into and perform its obligations under such an agreement; provided, further, however, that a Holder will not by any provision in this Agreement be required to enter into any agreement or undertaking in connection with
any registration in this Section 1 providing for any indemnification or contribution on the part of the Holder greater than the Holder’s obligations under Section 1.7 hereof; 

(g) notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes any untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, such obligation to continue for ninety (90) days; and 

(h) use commercially reasonable efforts to furnish, at the request of any Holder requesting registration of Registrable Securities pursuant to
this Section 1, on the date that such Registrable Securities are delivered to the underwriters for sale in connection with a registration pursuant to this Section 1, if such securities are being sold through underwriters, (i) an
opinion, dated such date, of the counsel representing the Company for the purposes of such registration, in form and substance as is customarily given to underwriters in an underwritten public offering addressed to the underwriters and to the
Holders requesting registration of Registrable Securities and (ii) a letter dated such date, from the independent certified public accountants of the Company, in form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering, addressed to the underwriters, if any, and to the Holders requesting registration of Registrable Securities. 

1.7 Indemnification 

(a) The Company will indemnify each Holder, each of its officers, directors and partners, members, legal counsel, and accountants 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 1, 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 any untrue statement (or alleged untrue statement) of a material fact contained 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 based on 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 any violation by the Company of the Securities
Act, the Exchange Act, any state securities law, or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration, qualification, or
compliance, and the Company will reimburse each such Holder, each of its officers, directors, members, partners, 

  
 9 

 
legal counsel, and accountants 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
expense arises out of or is based on any untrue statement or omission based upon written information furnished to the Company by such Holder or underwriter and stated to be specifically for use therein. It is agreed that the indemnity agreement
contained in this Section 1.7(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). 
 (b) Each Holder will, if Registrable Securities held by such Holder are included in the securities as to which
such registration, qualification, or compliance is being effected, indemnify 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 Other Stockholder, and each of their officers, directors, partners, members, and
each person controlling such Holder or Other Stockholder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on any untrue statement (or alleged untrue statement) of a material fact contained
in any such registration statement, prospectus, offering circular, or other document, or 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,
and such Holder will reimburse the Company and such other Holders, Other Stockholders, directors, officers, partners, legal counsel, and accountants, persons, underwriters, 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, that such untrue statement (or alleged untrue statement) or omission (or alleged 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 1.7 exceed the net proceeds from the offering received by such Holder, except in the case of willful
fraud by such Holder. 
 (c) Each party entitled to indemnification under this Section 1.7 (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

  
 10 

 
any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this Section 1, 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 1.7 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; provided, that in no event shall any contribution by a Holder hereunder exceed the net proceeds from the
offering received by such Holder, except in the case of willful fraud by such Holder. 
 (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. 
 (f) The obligations of the Company and Holders under this Section 1.7 shall survive the completion
of any offering of Registrable Securities in a registration statement under this Section 1. 
 1.8 Information by
Holder Each Holder of Registrable Securities shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification, or compliance referred to in this Section 1. 
 1.9
Limitations on Subsequent Registration Rights From and after the date of this Agreement, the Company shall not, without the prior written consent of Holders representing at least fifty-three percent (53%) of the Registrable Securities
then outstanding, 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 pari passu or senior to the

  
 11 

 
registration rights granted to the Holders hereunder except for pari passu registration rights unanimously approved by the Company’s Board of Directors and granted for
securities issuable upon the exercise of warrants issued in connection with debt financing by banks or equipment lessors. 
 1.10 Rule
144 Reporting With a view to making available the benefits of certain rules 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 available, as those terms are understood and defined in Rule 144
of the Securities Act or any similar or analogous rule promulgated under the Securities Act, at all times after the effective date of the first registration 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 
 (c) So long as a Holder owns any Restricted
Securities, furnish to the Holder forthwith upon written request: (i) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 of the Securities Act and the Exchange Act (at any time after it has
become subject to such reporting requirements), (ii) a copy of the most recent annual or quarterly report of the Company and (iii) 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. 
 1.11 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 1 may be transferred or assigned by a Holder only to a Permitted Transferee, provided that the Company
is given written notice at the time of or within a reasonable time after 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 being
transferred or assigned, and, provided further, that the transferee or assignee of such rights assumes in writing the obligations of such Holder under this Section 1. 

1.12 “Market Stand-Off” Agreement Each Holder hereby agrees that such Holder shall not sell, offer, pledge, contract
to sell, grant any option or contract to purchase, purchase any option or contract to sell, grant any right or warrant to purchase, lend or otherwise transfer or encumber, directly or indirectly, any Common Stock (or other securities) of the Company
held by such Holder as of the date of such “lock-up” or “market-standoff” agreement, nor shall the Holder enter into any swap, hedging or other arrangement that transfers to another, in
whole or in part, any of the economic consequences of ownership of any Common Stock (or other securities) during the one hundred eighty (180) day period following the effective date of a registration statement of the Company filed in connection
with the Company’s initial public offering under the Securities Act (the “Lock-Up Period”); provided that all officers and directors of the Company and holders of at least
one percent (1%) of the Company’s voting securities are either bound by, or have agreed to be bound 

  
 12 

 
by, similar agreements; and provided further, that, if applicable to the Company, for the purpose of compliance with NASD Rule 2711(f)(4) or any successor provisions or amendments
thereto, if (i) during the last 17 days of the initial Lock-Up Period, the Company releases earnings results or material news or a material event relating to the Company occurs or (ii) prior to the
expiration of the initial Lock-Up Period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the initial Lock-Up Period, then in each case, Purchaser hereby consents to an extension to the Lock-Up Period until the expiration of the 18-day
period beginning on the date of release of the earnings results or the occurrence of the material news or material event, as applicable, unless such extension is waived in writing. The obligations described in this Section 1.12 shall not
apply to a registration relating solely to employee benefit plans on Form S-1 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 1.1(b) hereof with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one hundred eighty (180) day period. Any discretionary waiver or
termination of the restrictions of such “lock-up” or “market-standoff” agreements (including this Agreement) by the Company or the managing underwriter shall apply to all Holders subject to
such agreements on a pro rata basis, based upon the number of shares held by such Holder. Each Holder agrees, if so requested by the Company or any representative of the underwriters, to execute such underwriters standard form of “lock-up” or “market standoff” agreement in a form satisfactory to the underwriters and the Company and consistent with the provisions of this Section 1.12. 

1.13 Allocation of Registration Opportunities Subject to compliance with Sections 1.2(c) and 1.3(b), in any circumstance in
which all of the Registrable Securities requested to be included in a registration on behalf of the Holders cannot be so included as a result of limitations of the aggregate number of shares of Registrable Securities that may be so included, the
number of shares of Registrable Securities that may be so included shall be allocated among the Holders requesting inclusion of shares pro rata on the basis of the number of shares of Registrable Securities that would be held by such Holders,
assuming conversion; provided, however, that such allocation shall not operate to reduce the aggregate number of Registrable Securities to be included in such registration, if any Holder does not request inclusion of the maximum number
of shares of Registrable Securities allocated to him pursuant to the above-described procedure, in which case the remaining portion of his allocation shall be reallocated among those requesting Holders whose allocations did not satisfy their
requests pro rata on the basis of the number of shares of Registrable Securities which would be held by such Holders, assuming conversion, and this procedure shall be repeated until all of the shares of Registrable Securities which may be
included in the registration on behalf of the Holders have been so allocated. The Company shall not limit the number of Registrable Securities to be included in a registration pursuant to this Agreement in order to include shares held by
stockholders with no registration rights pursuant to this Agreement or to include shares of stock issued to founders of the Company or to employees, officers, directors, or consultants pursuant to the Company’s stock, option or other equity
incentive plans, or in the case of registrations under Sections 1.2 or 1.5 hereof, in order to include in such registration securities registered for the Company’s own account, without the consent of Holders holding at least
fifty-three percent (53%) of the Registrable Securities. 

  
 13 

 1.14 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 1. 

1.15 Termination of Registration Rights The right of any Holder to request registration or inclusion in any registration
pursuant to Section 1.2, 1.3 or 1.5 shall terminate on the earlier of (i) such date after the closing of the first registered public offering of Common Stock of the Company as all shares of Registrable Securities held
or entitled to be held upon conversion by such Holder, together with its affiliates, 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.

of the liability of director to the maximum extent permitted by law and (b) for indemnification of directors for acts on behalf of the Company to the maximum extent permitted by law. Upon the approval by the Board of Directors of the Company,
including a majority of the directors designated by the holders of Preferred Stock, the Company shall obtain Director and Officer Liability Insurance in an amount reasonable for a company its size and in its industry as determined by the
Company’s Board of Directors.  
 2.7 Termination of Covenants  

The covenants set forth in this Section 2 (other than Sections 2.2 and 2.6) shall terminate and be of no further force and effect upon
the earlier to occur of (i) a Qualified Public Offering or (ii) a Liquidation Event as defined in Article V of the Company’s Certificate of Incorporation. Notwithstanding the forgoing, the covenants set forth in Section 2.1 will
terminate on the first date on which the Company becomes subject to the reporting requirements of the Exchange Act of 1934. 

Section 3 
 Right
of First Refusal 
 3.1 Right of First Refusal 

The Company hereby grants to each Major Holder, the right of first refusal to purchase a pro rata share of New Securities (as defined
in this Section 3.1) which the Company may, from time to time, propose to sell and issue. A Major Holder’s “pro rata share”, for purposes of this right of 

  
 16 

 
first refusal, is the ratio of the number of shares of Common Stock owned by such Major Holder immediately prior to the issuance of New Securities issued or issuable upon conversion of the
Shares, to the total number of shares of Common Stock owned by all Major Holders immediately prior to the issuance of New Securities, assuming full conversion of the Shares and all shares of Preferred Stock then owned by the Major Holders. Each
Major Holder shall have a right of over-allotment such that if any Major Holder fails to exercise its right hereunder to purchase its pro rata share of New Securities, then the Company shall promptly notify in writing (the “Company
Notice”) the Major Holders who have exercised such rights of the unsubscribed shares of New Securities and shall offer such Major Holders the right to acquire such unsubscribed New Securities on a pro rata basis within ten
(10) days from the date of receipt of the Company Notice. 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, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, convertible into capital stock; provided that the term “New
Securities” does not include: 
 (i) shares of Common Stock issued or issuable upon conversion of Preferred Stock; 

(ii) up to 25,975,000 shares of Common Stock (as presently constituted and subject to subsequent adjustment for stock splits, stock
dividends, reverse stock splits and the like) issued or issuable to officers, directors and employees of, or consultants to, the Company pursuant to stock grants, option plans, purchase plans or other employee stock incentive programs or
arrangements unanimously approved by the Board of Directors of the Company, or upon exercise of options or warrants granted to such parties pursuant to any such plan or arrangement (provided that any options for such shares that expire or terminate
unexercised or any restricted stock repurchased by the Company at cost shall not be counted toward such maximum number unless and until such shares are regranted as new stock grants (or as new options) pursuant to the terms of any such plan,
incentive program or arrangement); provided, further that a greater number of shares of Common Stock may be issued pursuant to such plans, incentive programs or arrangements if approved by the Board of Directors of the Company, including at least
two (2) of the Preferred Directors; 
 (iii) shares of Common Stock, options or convertible securities issued to financial
institutions or lessors in connection with commercial credit arrangements, equipment financings, commercial property lease transactions or similar transactions approved unanimously by the Board of Directors of the Company;

date of this Agreement; 
 (v) shares of Common Stock issued in a Qualified Public Offering; 

  
 17 

 (vi) shares of Common Stock issued or issuable as a dividend or distribution on Preferred Stock
or pursuant to any event for which adjustment is made pursuant to paragraph 4(e), 4(f), 4(g) and 4(h) of the Certificate of Incorporation of the Company; 

(vii) shares of Common Stock, options or convertible securities issued in connection with bona fide acquisitions, mergers or similar
transactions, the terms of which are approved by the Board of Directors of the Company, including a majority of the directors designated by the holders of Preferred Stock; 

(viii) shares of Common Stock issued or issuable to any entity as a component of any business relationship with such entity for the purpose
of (A) joint venture, technology licensing or development activities, (B) distribution, supply or manufacture of the Company’s products or services or (C) any other arrangement involving corporate partners that are primarily for
purposes other than raising capital, the terms of which business relationship with such entity are approved unanimously by the Board of Directors of the Company. 

(ix) shares of Common Stock or Preferred Stock of the Company which are otherwise excluded by the affirmative vote or consent of the holders
of at least fifty-three percent (53%) of the Registrable Securities; 
 (x) up to 15,000,000 shares of Series AA Preferred Stock (as
presently constituted and subject to subsequent adjustment for stock splits, stock dividends, reverse stock splits and the like); and 

(xi) any right, option or warrant to acquire any security convertible into the securities excluded from the definition of New Securities
pursuant to subsections (i) through (x) above. 
 (b) In the event the Company proposes to undertake an issuance of New Securities, it
shall give each Holder written notice of its intention, describing the type of New Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Holder shall have fifteen (15) days after any such
notice is mailed or delivered to agree to purchase such Holder’s pro rata share of such New Securities for the price and upon the terms specified in the notice by giving written notice to the Company and stating therein the quantity of New
Securities to be purchased. 
 (c) In the event the Holders fail to exercise fully the right of first refusal within said fifteen
(15) day period and after the expiration of the additional ten (10) day period for the exercise of the over-allotment provisions of this Section 3.1, 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 the New Securities respecting which the Holders’ right of first refusal
option set forth in this Section 3.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to the Holders pursuant to Section 3.1(b). In the event
the Company has not sold within such ninety (90) day period or entered into an agreement to sell the 

  
 18 

 
New Securities in accordance with the foregoing within sixty (60) days from the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first again
offering such securities to the Holders in the manner provided in Section 3.1(b) above. 
 (d) The right of first refusal
granted under this Agreement shall expire and be of no further force and effect upon a Qualified Public Offering or a Liquidation Event as defined in Article V of the Company’s Certificate of Incorporation. 

(e) The right of first refusal set forth in this Section 3.1 may only be assigned or transferred pursuant to the provisions relating to
the transfer of registration rights set forth in Section 1.11 hereof. 
 (f) The right of first refusal set forth in this
Section 3.1 shall not be applicable with respect to any Holder and any subsequent securities issuance, if (i) at the time of such subsequent securities issuance, the Holder is not an “accredited investor,” as that term is
defined in Rule 501(a) under the Securities Act, and (ii) such subsequent securities issuance is otherwise being offered only to accredited investors.

140 Scott Drive, California 94025, facsimile number (650) 463-2600. 
 Each such notice or other

regularly maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid. 
 4.4 Governing
Law This Agreement shall be governed in all respects by the internal laws of the State of California as applied to agreements entered into among California residents to be performed entirely within California, without regard to principles of
conflicts of law. 
 4.5 Successors and Assigns This Agreement, and any and all rights, duties and obligations hereunder,
shall not be assigned, transferred, delegated or sublicensed by any Holder without the prior written consent of the Company, except to a Permitted Transferee. Except as set forth in the preceding sentence, any attempt by a Holder to assign,
transfer, delegate or sublicense 

  
 22 

 
any rights, duties or obligations that arise under this Agreement shall be void. Subject to the foregoing and except as otherwise provided herein, the provisions of this Agreement shall inure to
the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties. 
 4.6 Waiver of
Right of First Refusal By signing this Agreement, the Existing Investors, representing at least sixty percent (60%) of the Registrable Securities (excluding any of such shares that have been sold to the public pursuant to Rule 144)
immediately prior to the date of this Agreement, hereby waive the Right of First Refusal set forth in Section 3 of the Prior Rights Agreement and any notice requirements related thereto with respect to the Company’s issuance and sale of
shares of Series AA Preferred Stock. 
 4.7 Entire Agreement The Company and the Existing Investors representing more than
sixty percent (60%) of the Registrable Securities held by all Holders (excluding any of such shares that have been sold to the public or pursuant to Rule 144) hereby amend and restate the Prior Rights Agreement with this Agreement pursuant to
Section 4.2 of the Prior Rights Agreement. This Agreement and the exhibits hereto, the Purchase Agreement and the documents delivered pursuant thereto constitute the full and entire understanding and agreement between the parties with regard to
the subjects hereof. No party hereto shall be liable or bound to any other party in any manner with regard to the subjects hereof or thereof by any warranties, representations or covenants except as specifically set forth herein or therein. Each
party expressly represents and warrants that it is not relying on any oral or written representations, warranties, covenants or agreements outside of this Agreement. 

4.8 Delays or Omissions Except as expressly provided herein, no delay or omission to exercise any right, power or remedy
accruing to any party to this Agreement upon any breach or default of any other party under this Agreement shall impair any such right, power or remedy of such non-defaulting party, nor shall it be construed
to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of
this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies, either under this Agreement or by law or otherwise afforded to any party to this Agreement, shall be cumulative and
not alternative. 
 4.9 Severability Unless otherwise expressly provided herein, the rights of the Holders hereunder are
several rights, not rights jointly held with any of the other Holders. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue
in full force and effect without said provision, and the parties agree to negotiate, in good faith, a legal and enforceable substitute provision which most nearly effects the parties’ intent in entering into this Agreement. 

4.10 Titles and Subtitles The titles and subtitles used in this Agreement are used for convenience only and are not to be
considered in construing or interpreting this Agreement. All references in this Agreement to sections, paragraphs and exhibits shall, unless otherwise provided, refer to sections and paragraphs hereof and exhibits attached hereto.

number of counterparts, each of, which shall be enforceable against the parties that execute such counterparts, and all of which together shall constitute one instrument. This Agreement may be executed via facsimile.

exclusive jurisdiction of, and venue in, the state courts in Santa Clara County in the State of California (or in the event of exclusive federal jurisdiction, the courts of the Northern District of California). 

4.13 Further Assurances Each party hereto agrees to execute and deliver, by the proper exercise of its corporate, limited
liability company, partnership or other powers, all such other and additional instruments and documents and do all such other acts and things as may be necessary to more fully effectuate this Agreement. 

4.14 Attorney’s Fees In the event that any suit or action is instituted under or in relation to this Agreement, including
without limitation to enforce any provision in this Agreement, the prevailing party in such dispute shall be entitled to recover from the losing party all fees, costs and expenses of enforcing any right of such prevailing party under or with respect
to this Agreement, including without limitation, such reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals. 

4.15 Aggregation All shares held or acquired by affiliated persons, funds and entities and constituent partners and members will
