the Company, that such disposition will not require registration of such shares under the Securities Act. It is agreed that the Company will not require opinions of counsel for transactions made
pursuant to Rule 144, except in unusual circumstances. After its Initial Offering, the Company will not require any transferee pursuant to Rule 144 to be bound by the terms of this Agreement if the shares so transferred do not remain Registrable
Securities hereunder following such transfer. 
 (b) Notwithstanding the provisions of subsection (a) above, no such restriction shall
apply to a transfer by a Holder that is (A) a partnership transferring to its partners or former partners in accordance with partnership interests, (B) a corporation transferring to a wholly-owned subsidiary or its stockholders in
accordance with their ownership interest, (C) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company, or (D) an individual transferring to the

OFFERED, SOLD OR OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS AND UNTIL REGISTERED UNDER THE ACT OR UNLESS THE COMPANY HAS RECEIVED AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT
REQUIRED. 
 THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
CONDITIONS OF A CERTAIN INVESTOR RIGHTS AGREEMENT BY AND BETWEEN THE STOCKHOLDER AND THE COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY. 

(d) The Company shall be obligated to reissue promptly unlegended certificates at the request of any Holder thereof if the Company has
completed its Initial Offering and the Holder shall have obtained an opinion of counsel (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 registration, qualification and legend, and provided that second legend listed above shall be removed only at such time as the Holder of such certificate is no longer subject to any restrictions hereunder. 

(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.

 2.2 Demand Registration. 

(a) Subject to the conditions of Section 2.2(c), if the Company shall receive a written request from the holders of at least a majority of the
Shares (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of all or part of the Registrable Securities then outstanding having an aggregate offering
price of at least $5,000,000, then the Company shall, within thirty (30) days of the receipt thereof, give written notice of such request to all Holders, and subject to the limitations of this Section 2.2, effect, as expeditiously as
reasonably possible, the registration under the Securities Act of all Registrable Securities that all Holders request to be registered. 

(b) If the Initiating Holders intend to distribute the Registrable Securities covered by their request by means of an underwriting, they shall
so advise the Company as a part of their request made pursuant to this Section 2.2 or any request pursuant to Section 2.4 and the Company shall include such information in the written notice referred to in Section 2.2(a) or Section 2.4(a),
as applicable. In such event, the right of any Holder to include its Registrable Securities in such registration shall be conditioned upon such Holder’s participation in such underwriting and the inclusion of such Holder’s Registrable
Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall enter into an underwriting agreement in customary form with the underwriter or underwriters selected
for such underwriting by the Holders of a majority of the Registrable Securities held by all Initiating Holders (which underwriter or underwriters shall be reasonably acceptable to the Company). Notwithstanding any other provision of this
Section 2.2 or Section 2.4, if the underwriter advises the Company that marketing factors require a limitation of the number of securities to be underwritten (including Registrable Securities) then the Company shall so advise all Holders
of Registrable Securities which would otherwise be underwritten pursuant hereto, and the number of shares that may be included in the underwriting shall be allocated to the Holders of such Registrable Securities on a pro rata basis based on
the number of Registrable Securities held by all such Holders (including the Initiating Holders); provided, however, that the number of shares of Registrable Securities to be included in such underwriting and registration shall not be reduced
unless all other securities of the Company are first entirely excluded from the underwriting and registration. Any Registrable Securities excluded or withdrawn from such underwriting shall be withdrawn from the registration. 

(c) The Company shall not be required to effect a registration pursuant to this Section 2.2: 

(i) prior to the earlier of (A) the third anniversary of the date of this Agreement or
(B) one hundred eighty (180) days following the effective date of the registration statement pertaining to the Initial Offering; 

  
 - 5 - 








 (ii) after the Company has effected two
(2) registrations pursuant to this Section 2.2, and such registrations have been declared or ordered effective; 

(iii) if the Company shall furnish to Holders requesting a registration statement pursuant to this Section 2.2, a
certificate signed by the Chairman of the Board (or, if no Chairman has been appointed, then the Chief Executive Officer or President of the Company) stating that in the good faith judgment of the Board, it would be seriously detrimental to the
Company and its stockholders for such registration statement to be effected at such time, in which event the Company shall have the right to defer such filing for a period of not more than ninety (90) days after receipt of the request of the
Initiating Holders; provided that such right to delay a request shall be exercised by the Company not more than once in any twelve (12) month period; 

(iv) if within thirty (30) days of receipt of a written request from Initiating Holders pursuant to Section 2.2(a),
the Company gives notice to the Holders of the Company’s intention to file a registration statement for its Initial Offering within ninety (90) days; 

(v) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be
immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.4 below; or 
 (vi) in any
particular jurisdiction in which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 

2.3 Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in
writing at least fifteen (15) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company solely for cash (excluding Special Registration Statements) and will
afford each such Holder an opportunity to include in such registration statement all or part of such Registrable Securities held by such Holder; provided that such notice and inclusion rights shall not apply to the Initial Offering unless
stockholders other than the Holders are offered the opportunity to include their shares in the Initial Offering and related registration. In no event shall the proviso in the preceding sentence be construed as an obligation of the Company to offer
all stockholders other than Holders the opportunity to participate in the Initial Offering and related registration. Each Holder desiring to include in any such registration statement all or any part of the Registrable Securities held by it shall,
within fifteen (15) days after the above-described notice from the Company, so notify the Company in writing. Such notice shall state the intended method of disposition of the Registrable Securities by such Holder. 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. 

  
 - 6 - 








 (a) Underwriting. If the registration statement under which the Company gives notice under
this Section 2.3 is for an underwritten offering, the Company shall so advise the Holders of Registrable Securities. In such event, the right of any such Holder to include Registrable Securities in a registration pursuant to this
Section 2.3 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 Registrable Securities through such underwriting shall enter into an underwriting agreement with the underwriter or underwriters selected for such underwriting by the Company reflecting the terms of the underwriting as agreed upon between the
Company and such underwriters. Notwithstanding any other provision of this Agreement, if the underwriter determines in good faith that marketing factors require a limitation of the number of shares to be underwritten, the number of shares that may
be included in the underwriting shall be allocated, first, to the Company; second, to the Holders on a pro rata basis based on the total number of Registrable Securities held by such Holders; and third, to any stockholder of the Company
(other than a Holder) on a pro rata basis; provided, however, that no such reduction shall reduce the amount of securities of the selling Holders included in the registration below thirty-three percent (33%) of the total amount of
securities included in such registration, unless such registration relates to the Initial Offering, in which case the selling Holders may be excluded further if the underwriters make the determination described above and no other stockholders’
securities are included in such registration. In no event will shares of any other selling stockholder be included in such registration without the written consent of those Holders of a majority of the Registrable Securities held by the Investors
and proposed to be sold in the offering if such inclusion would reduce the number of shares that may be included by Holders. If any Holder disapproves of the terms of any such underwriting, such Holder may elect to withdraw therefrom by written
notice to the Company and the underwriter, delivered at least ten (10) business days prior to the effective date of the registration statement. Any Registrable Securities excluded or withdrawn from such underwriting shall be excluded and
withdrawn from the registration. For any Holder which is a partnership, limited liability company or corporation, the partners, retired partners, members, retired members and stockholders of such Holder, or the estates and family members of any such
partners, retired partners, members and retired members and any trusts for the benefit of any of the foregoing person shall be deemed to be a single “Holder,” and any pro rata reduction with respect to such “Holder” shall be
based upon the aggregate amount of shares carrying registration rights owned by all entities and individuals included in such “Holder,” as defined in this sentence. 

(b) Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it under
this Section 2.3 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration, and shall promptly notify any Holder that has elected to include shares in such registration of
such termination or withdrawal. The Registration Expenses of such withdrawn registration shall be borne by the Company in accordance with Section 2.5 hereof. 

2.4 Form S-3 Registration. In case the Company shall receive from any Holder or Holders of
Registrable Securities a written request or requests that the Company effect a registration on Form S-3 (or any successor to Form S-3) or any similar short-form registration statement and any related qualification or compliance with respect to all
or a part of the Registrable Securities owned by such Holder or Holders, the Company will: 
 (a) promptly give written notice of the
proposed registration, and any related qualification or compliance, to all other Holders of Registrable Securities; and 

  
 - 7 - 








 (b) as soon as practicable, effect such registration and all such qualifications and compliances
as may be so requested and as would permit or facilitate the sale and distribution of all or such portion of such Holder’s or Holders’ Registrable Securities as are specified in such request, together with all or such portion of the
Registrable Securities of any other Holder or Holders joining in such request as are specified in a written request given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company
shall not be obligated to effect any such registration, qualification or compliance pursuant to this Section 2.4: 
 (i) if
Form S-3 is not available for such offering by the Holders, or 
 (ii) if the Holders, together
with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other securities (if any) at an aggregate price to the public of less than one million dollars
($1,000,000), or 
 (iii) if within thirty (30) days of receipt of a written request from any Holder or Holders
pursuant to this Section 2.4, the Company gives notice to such Holder or Holders of the Company’s intention to make a public offering within ninety (90) days, other than pursuant to a Special Registration Statement, provided
that such Holders will be permitted to register such shares in such public offering as requested to be registered pursuant to Section 2.3 hereof without reduction by the underwriter thereof, or 

(iv) if the Company shall furnish to the Holders a certificate signed by the Chairman of the Board stating that in the
good faith judgment of the Board, it would be seriously detrimental to the Company and its stockholders for such Form S-3 registration to be effected at such time, in which event the Company shall have the right to defer the filing of the Form S-3
registration statement for a period of not more than ninety (90) days after receipt of the request of the Holder or Holders under this Section 2.4; provided, that such right to delay a request shall be exercised by the Company not
more than once in any twelve (12) month period, or 
 (v) in any particular jurisdiction in
which the Company would be required to qualify to do business or to execute a general consent to service of process in effecting such registration, qualification or compliance. 

(c) Subject to the foregoing, the Company shall file a Form S-3 registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt of the requests of the Holders. Registrations effected pursuant to this Section 2.4 shall not be counted as demands for registration or registrations effected
pursuant to Section 2.2. 
 2.5 Expenses of Registration. Except as
specifically provided herein, all Registration Expenses incurred in connection with any registration, qualification or compliance pursuant to Section 2.2 or any registration under Section 2.3 or Section 2.4 herein shall be borne


  
 - 8 - 








 
by the Company. All Selling Expenses incurred in connection with any registrations hereunder, shall be borne by the holders of the securities so registered pro rata on the basis of the
number of shares so registered. The Company shall not, however, be required to pay for expenses of any registration proceeding begun pursuant to Section 2.2 or 2.4, the request of which has been subsequently withdrawn by the Initiating Holders
unless (a) the withdrawal is based upon material adverse information concerning the Company of which the Initiating Holders were not aware at the time of such request or (b) the Holders of a majority of Registrable Securities agree to deem
such registration to have been effected as of the date of such withdrawal for purposes of determining whether the Company shall be obligated pursuant to Section 2.2(c) to undertake any subsequent registration, in which event such right shall be
forfeited by all Holders). 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 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 pursuant to clause (a) above, then such registration shall not be deemed to have been effected for purposes of
determining whether the Company shall be obligated pursuant to Section 2.2(c) to undertake any subsequent registration. 
 2.6
Obligations of the Company. Whenever required to effect the registration of any Registrable Securities, the Company shall, as expeditiously as reasonably possible: 

(a) prepare and file with the SEC a registration statement with respect to such Registrable Securities and use commercially reasonable efforts
to cause such registration statement to become effective, and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement effective for a period of up to 270 days or, if
earlier, until the Holder or Holders have completed the distribution related thereto; provided, however, that at any time, upon written notice to the participating Holders and for a period not to exceed sixty (60) days thereafter (the
“Suspension Period”), the Company may delay the filing or effectiveness of any registration statement or suspend the use or effectiveness of any registration statement (and the Initiating Holders hereby agree not to offer or sell any
Registrable Securities pursuant to such registration statement during the Suspension Period) if the Company reasonably believes that there is or may be in existence material nonpublic information or events involving the Company, the failure of which
to be disclosed in the prospectus included in the registration statement could result in a Violation (as defined below). In the event that the Company shall exercise its right to delay or suspend the filing or effectiveness of a registration
hereunder, the applicable time period during which the registration statement is to remain effective shall be extended by a period of time equal to the duration of the Suspension Period. The Company may extend the Suspension Period for an additional
consecutive sixty (60) days with the consent of the holders of a majority of the Registrable Securities registered under the applicable registration statement, which consent shall not be unreasonably withheld. In no event shall any Suspension
Period, when taken together with all prior Suspension Periods, exceed 120 days in the aggregate. If so directed by the Company, all Holders registering shares under such registration statement shall (i) not offer to sell any Registrable
Securities pursuant to the registration statement during the period in which the delay 

  
 - 9 - 








 
or suspension is in effect after receiving notice of such delay or suspension; and (ii) use their best efforts to deliver to the Company (at the Company’s expense) all copies, other
than permanent file copies then in such Holders’ possession, of the prospectus relating to such Registrable Securities current at the time of receipt of such notice. Notwithstanding the foregoing, the Company shall not be required to file,
cause to become effective or maintain the effectiveness of any registration statement other than a registration statement on Form S-3 that contemplates a distribution of securities on a delayed or continuous basis pursuant to Rule 415 under the
Securities Act. 
 (b) Prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used
in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection
(a) above. 
 (c) Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with
the requirements of the Securities Act, and such other documents as they may reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 

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

 (f) Notify each Holder of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing. The Company will use commercially reasonable efforts to amend or supplement such prospectus in
order to cause such prospectus not to include any 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 in the light of the circumstances then
existing. 
 (g) Use commercially reasonable efforts to furnish, on the date that such Registrable Securities are delivered to the
underwriters for sale, if such securities are being sold through underwriters, (i) an opinion, dated as of 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, if any, and (ii) a 

  
 - 10 - 








 
letter, dated as of 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. 
 2.7 Termination
of Registration Rights. All registration rights granted under this Section 2 shall terminate and be of no further force and effect five (5) years after the date of the Company’s Initial Offering. 

2.8 Delay of Registration; Furnishing Information. 

(a) No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of
any controversy that might arise with respect to the interpretation or implementation of this Section 2. 
 (b) It shall be a condition
precedent to the obligations of the Company to take any action pursuant to Section 2.2, 2.3 or 2.4 that the selling Holders shall furnish to the Company such information regarding themselves, the Registrable Securities held by them and the
intended method of disposition of such securities as shall be reasonably required to effect the registration of their Registrable Securities. 

(c) The Company shall have no obligation with respect to any registration requested pursuant to Section 2.2 or Section 2.4 if, due
to the operation of subsection 2.2(b), the number of shares or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of shares or the anticipated aggregate
offering price required to originally trigger the Company’s obligation to initiate such registration as specified in Section 2.2 or Section 2.4, whichever is applicable. 

2.9 Indemnification. In the event any Registrable Securities are included in a registration statement under Sections 2.2, 2.3 or
2.4: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each Holder, the partners, members, officers and
directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of
or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue statement or alleged untrue statement of a material fact contained in such
registration statement or incorporated by reference therein, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged omission to state therein a material
fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement; and the Company will reimburse each such Holder, partner, member, officer,
director, underwriter or controlling 

  
 - 11 - 








 
person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action if it is judicially determined
that there was such a Violation by the Company; provided, however, that the indemnity agreement contained in this Section 2.9(a) shall not apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it arises out of
or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, member, officer, director, underwriter or controlling
person of such Holder. 
 (b) To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included
in the securities as to which such registration qualifications or compliance is being effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Holder selling securities under such registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages
or liabilities (joint or several) to which the Company or any such director, officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the
Securities Act, the Exchange Act or other federal or state law, insofar as such losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information furnished by such Holder and stated to be specifically for use in connection with such registration (a “Holder Violation”); and each such Holder
will reimburse any legal or other expenses reasonably incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with
investigating or defending any such loss, claim, damage, liability or action if it is judicially determined that there was such a Holder Violation; provided, however, that the indemnity agreement contained in this Section 2.9(b) shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided further, that in no event
shall any indemnity under this Section 2.9 exceed the net proceeds from the offering received by such Holder. 
 (c) Promptly after
receipt by an indemnified party under this Section 2.9 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party
under this Section 2.9, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent the indemnifying party so desires, jointly with any
other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right to retain its own counsel, with the fees and
expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any
other party represented by such 

  
 - 12 - 








 
counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party
of any liability to the indemnified party under this Section 2.9 to the extent, and only to the extent, prejudicial to its ability to defend such action, but the omission so to deliver written notice to the indemnifying party will not relieve
it of any liability that it may have to any indemnified party otherwise than under this Section 2.9. 
 (d) If the indemnification
provided for in this Section 2.9 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of
indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability 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 Violation(s) or Holder Violation(s) that resulted in such loss, claim, damage or liability, as well
as any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law 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. 

(e) The obligations of the Company and Holders under this Section 2.9 shall survive completion of any offering of Registrable Securities
in a registration statement and, with respect to liability arising from an offering to which this Section 2.9 would apply that is covered by a registration filed before termination of this Agreement, such termination. 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 which 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. 
 2.10
Assignment of Registration Rights. The rights to cause the Company to register Registrable Securities pursuant to this Section 2 may be assigned by a Holder to (i) any partner or retired partner of such Holder which is a
partnership, (ii) any member or former member of such Holder which is a limited liability company, (iii) any affiliate of such Holder; (iv) any family member or trust for the benefit of such individual Holder or (v) any Holder
that acquires a sufficient number of shares of Registrable Securities to qualify as a Major Investor; provided, however, (i) the transferor shall, within ten (10) days after such transfer, furnish to the Company written notice of
the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement. 

2.11 Amendment of Registration Rights. Any provision of this Section 2 may be amended and the observance thereof may
be waived (either generally or in a particular instance and either retroactively or prospectively), only with the written consent of the Company and those Investors holding at least 75% of the Registrable


  
 - 13 - 








 
Securities then held by Investors. Any amendment or waiver effected in accordance with this Section 2.11 shall be binding upon each Holder and the Company. By acceptance of any benefits
under this Section 2, Holders of Registrable Securities hereby agree to be bound by the provisions hereunder. 
 2.12
Limitation on Subsequent Registration Rights. Other than as provided in Section 5.10, after the date of this Agreement, the Company shall not, without the prior written consent of those Holders of at least 75% of the Registrable
Securities then outstanding held by the Investors, enter into any agreement with any holder or prospective holder of any securities of the Company that would grant such holder registration rights on a parity with or senior to those granted to the
Holders hereunder, other than the right to a Special Registration Statement. 
 2.13 “Market Stand-Off”
Agreement. Each Holder hereby agrees that such Holder shall not, without the prior written consent of the managing underwriter, sell, 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, any Common Stock (or other securities) of the Company held by such Holder (other than those included in the registration) for a period specified by the representative of the underwriters
of Common Stock (or other securities) of the Company not to exceed one hundred eighty (180) days following the effective date of a registration statement of the Company filed under the Securities Act; provided that: 

(i) such agreement shall apply only to the Company’s Initial Offering; 

(ii) all officers and directors of the Company and holders of at least one percent (1%) of the
Company’s voting securities enter into similar agreements; and 
 (iii) such agreement shall provide that any
discretionary waiver or termination of the restrictions of such agreement by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company shall apply pro rata to all Holders subject to such agreement,
based on the number of Registrable Securities then subject to such agreement. 
 2.14 Agreement to Furnish Information.
Each Holder agrees to execute and deliver such other agreements as may be reasonably requested by the Company or the underwriter that are consistent with the Holder’s obligations under Section 2.13 or that are necessary to give further
effect thereto. In addition, if requested by the Company or the representative of the underwriters of Common Stock (or other securities) of the Company, each Holder shall provide, within ten (10) days of such request, such information as may be
required by the Company or such representative in connection with the completion of any public offering of the Company’s securities pursuant to a registration statement filed under the Securities Act. The obligations described in
Section 2.13 and this Section 2.14 shall not apply to a Special Registration Statement. The Company may impose stop-transfer instructions with respect to the shares of Common Stock (or other securities) subject to the foregoing restriction
until the end of said one hundred eighty (180) day period. Each Holder agrees that any transferee of any shares of Registrable Securities shall be bound by Sections 2.13 and 2.14. The underwriters of the Company’s stock are intended third
party beneficiaries of Sections 2.13 and 2.14 and shall have the right, power and authority to enforce the provisions hereof as though they were a party hereto.

 2.15 Rule 144 Reporting. With a view to making available to the Holders the
benefits of certain rules and regulations of the SEC which may permit the sale of the Registrable Securities to the public without registration, the Company agrees that, at all times when the Company is subject to the reporting requirements of the
Securities Act and of the Exchange Act, it shall use its best efforts to: 
 (a) Make and keep public information available, as those terms
are understood and defined in SEC Rule 144 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 SEC, in a timely manner, all reports and other documents required of the Company under the Exchange Act; and

 (c) So long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request: a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144 of the Securities Act, and of 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 filed with the Commission; and such other reports and documents as a Holder may reasonably request in connection with availing itself of any rule or regulation of the SEC allowing it to sell any such securities without
registration.

often as may be reasonably requested; provided, however, that the Company shall not be obligated under this Section 3.3 with respect to a competitor of the Company (as reasonably determined by the Board) or with respect to information
which the Board determines in good faith is confidential or attorney-client privileged and should not, therefore, be disclosed. 

3.4 Confidentiality of Records. Each Investor agrees to keep confidential, and to use the same
degree of care as such Investor uses to protect its own confidential information to keep confidential any information furnished to such Investor pursuant to Section 3.1 and 3.2 hereof that the Company identifies as being confidential or
proprietary (so long as such information is not in the public domain), except that such Investor may disclose such proprietary or confidential information (i) to any partner, subsidiary or parent of such Investor as long as such partner,
subsidiary or parent is advised of and agrees or has agreed to be bound by the confidentiality provisions of this Section 3.3 or comparable restrictions; (ii) at such time as it enters the public domain through no fault of such Investor;
(iii) that is communicated to it free of any obligation of confidentiality; (iv) that is developed by Investor or its agents independently of and without reference to any confidential information communicated by the Company; or (v) as
required by applicable law.

the date of issuance or such person’s services commencement date with the company, and (b) eighty percent (80%) of such stock shall vest in equal annual installments over the remaining four (4) years. With respect to any shares of
stock purchased by any such person, the Company’s repurchase option shall provide that upon such person’s termination of employment or service with the Company, with or without cause, the Company or its assignee shall have the option to
purchase at cost any unvested shares of stock held by such person. 
 3.7 Key Man Insurance. The
Company shall maintain in full force and effect term life insurance in the amount of one million dollars ($1,000,000) on the life of Matthew Calkins (for so long as Mr. Calkins remains an employee of the Company); naming the Company as

3.8 Directors and Officers Insurance. The Company shall maintain, during the term of this Agreement,
its director and officer liability insurance with coverage limits of at least three million dollars ($3,000,000) per occurrence or such other coverage limits as may be reasonably determined by the Board to be acceptable (including the affirmative
approval of the Preferred Stock Designees). If requested by any of the Preferred Stock Designees, the Company will add one designee of NBVP or NEA 14, as applicable, as a notice party for such policy and shall request that the issuer of such policy
provide such designee with ten (10) days notice before such policy is terminated (for failure to pay premiums or otherwise) or assigned or before any change is made in the beneficiary thereof. In the event of a Change in Control (as defined
below), proper provisions shall be made so that successors of the Company assume the Company’s obligations with respect to the indemnification of Directors for a period of not less than five years. 

3.9 Board of Directors.

the committees thereof) and any other meetings or events attended on behalf of the Company at the Company’s request (such as trade shows) as a director.

(“NEA 14”) to attend and participate in all meetings of the Board and any committee thereof in a nonvoting capacity, and in connection therewith, the Company shall give such representatives copies of all notices, minutes,
consents and other materials, financial or otherwise, which the Company provides to its Board; provided, however, that the Company reserves the right to exclude such representatives from access to any


  
 - 18 - 








 
material or meeting or portion thereof if the Company believes upon advice of counsel that such exclusion is reasonably necessary to preserve the attorney-client privilege, to protect highly
confidential information or for other similar reasons; and provided, further, that such rights shall terminate in the event NBVP or NEA 14 no longer owns at least 20% of the Shares (or Registrable Securities issued upon conversion or exchange
therefor) it will have purchased pursuant to the Purchase Agreements. The decision of the Board with respect to the privileged or confidential nature of such information shall be final and binding. 

3.11 Compensation and Audit Committees. The Company shall maintain a Compensation Committee and an Audit Committee of the Board, each
consisting of no more than three (3) members of the Board. One Series A Designee and the Series B Designee shall be a member of each such committee. The Compensation Committee shall make recommendations to the Board with respect to (i) the
compensation or other remuneration at an annual rate in excess of two hundred fifty thousand dollars ($250,000), (ii) any severance pay or right to continued compensation from the Company following termination of services to the Company other than
that consistent with the Company’s then current policies, (iii) cash bonuses or sales commissions, (iv) salaries or positions which cannot be immediately changed by the Company, and (v) issuances or grants of capital stock (or

Company shall require all employees and consultants of the Company who begin work after the date hereof at the time they first begin working for the Company (whether as an employee or as a consultant) to execute and deliver a Proprietary Information

3.14 Directors’ Liability and Indemnification. 

(a) The Company’s Second Amended and Restated Certificate of Incorporation and Bylaws (as such Second Amended and Restated Certificate of
Incorporation and Bylaws may be amended from time to time) shall provide (a) for limitation of the liability of directors 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. In the event any suit is filed or claim is asserted against a director or former director of the Company as a result of such director’s or former director’s service on the Board, the Company will
provide such director or former director access to all records and files of the Company as he or she may reasonably request in defending against or preparing to defend against any such suit or claim. 

(b) The Company further agrees that it shall deliver an indemnification agreement in the form previously approved by the Board of Directors to
any person who becomes a member of the Board of Directors as a director elected by the holders of Preferred Stock after the date hereof. 

3.15 Qualified Small Business. The Company will use its commercially reasonable efforts to comply with the reporting and
recordkeeping requirements of Section 1202 of the Internal Revenue Code of 1986, as amended (the “Code”), any regulations promulgated thereunder and any similar state laws and regulations, and agrees not to repurchase
any stock of the Company if such repurchase would cause the Shares not to so qualify as “Qualified Small Business Stock,” so long as the Board (including all of the Preferred Stock Designees) determines that it is in the best
interests of and not unduly burdensome to the Company to comply with the provisions of Section 1202 of the Code. The Company further covenants to submit to state and federal taxation authorities, and to each Major Investor upon its reasonable
request, such form and filings as may be required to document the Company’s compliance with its franchise or income tax return for the current income year. 

3.16 Real Property Holding Corporation. The Company shall provide prompt notice to NEA 14 following any
“determination date” (as defined in Treasury Regulation Section 1.897-2(c)(1)) on which the Company becomes a United States real property holding corporation. In addition, upon a written request by NEA, the Company shall provide NEA 14

successor regulation, and the Company shall provide timely notice to the Internal Revenue Service, in accordance with and to the extent required by Treasury Regulation Section 1.897-2(h)(2) or any successor regulation, that such statement has been
made. 

  
 - 20 - 








 3.17 Use of Proceeds. The Company agrees that it will use the proceeds of
the sale of the Series B Preferred Stock for repurchases of 3,060,025 shares of its Common Stock, working capital and general corporate purposes, unless a majority of the Board, including the Preferred Stock Designees, approves other uses thereof.
For the avoidance of doubt, the Company agrees that it will repurchase all of such shares of Common Stock no later than two weeks after the date of this Agreement at a price of $12.2548 such that NEA 14 and/or its affiliates will own ten percent of
the Company on a fully-diluted basis once the repurchases are complete. 
 3.18 Market Stand-off. All outstanding
shares of Common Stock and preferred stock, and all future shares of Common Stock and preferred stock issuable upon the exercise or conversion of outstanding options, warrants or other exercisable or convertible securities shall be subject to a
market standoff or “lockup” agreement of not less than 180 days following the Company’s initial public offering. 

3.19 Press Release. Any press release issued by the Company in connection with, or referencing the Financing, must be
previously approved by NEA 14. Expenses in connection with such press release shall be paid for by the Company. 
 3.20 IPO Purchase
Rights. 
 (a) In the event the Company effects the Initial Offering, and to the extent permitted by applicable law, the Company shall
consult with the underwriters selected for such underwriting by the Company and request that such underwriters designate a number of shares equal to ten percent (10%) of the Common Stock to be offered in the Initial Offering (including any shares
eligible to be purchased by the underwriters upon exercise of their over-allotment option and any shares registered under a registration statement filed with the SEC pursuant to Rule 462(b) promulgated under the Securities Act) for sale under a
“directed shares program” and further request such underwriter to allocate fifty percent (50%) of such directed shares program to the Investors, providing to each Investor (or such Investor’s designees) the right to purchase in such
Initial Offering its pro rata portion (based on the ratio of (i) the number of shares of Common Stock of which such Investor is deemed to be a holder immediately prior to such Initial Offering (calculated on an as-converted to Common
Stock basis) to (ii) the total number of shares of Common Stock of which all Investors are deemed to be holders immediately prior to such offering (calculated on an as-converted to Common Stock basis)) of such allocation of publicly offered
securities (the “Reserved IPO Shares”). In this regard, the Company will use its commercially reasonable efforts to obtain the approval of the underwriters of the Initial Offering to the Investors’ purchase rights set
forth in this Section 3.20. In the selection of underwriters for the Initial Offering, in no event shall the willingness of any candidate for underwriter to agree to establish the Reserved IPO Shares be used as a condition for selection or a
requirement of an underwriter once selected. 
 (b) The sale of the Reserved IPO Shares shall be made under the then-applicable rules and
regulations of federal and applicable state securities laws and the Financial Industry Regulatory Authority (“FINRA”). Notwithstanding any other provision of this Section 3.20, if the underwriter advises the Company that
market factors require a limitation of the sale of Reserved IPO Shares, then the Company shall so advise each Investor and the number of Reserved IPO Shares shall be so reduced. 

  
 - 21 - 








 (c) In the event the Company is advised by the SEC or any other regulatory body with jurisdiction
over the Initial Offering that the offering or sale of Reserved IPO Shares to the Investors as described in paragraph (a) above is contrary to any U.S. federal or state securities laws or the rules or regulations of the SEC, FINRA, the Nasdaq
Stock Market, Inc. or any other regulatory body having jurisdiction over the Initial Offering, the Company shall provide written notice of such event to the Investors, and the Investors agree that their right to purchase Reserved IPO Shares pursuant
to paragraph (a) above shall be deemed waived without any further action by the Investors but only to the extent necessary to comply with such applicable laws, rules and regulations; provided that (x) the Company has used its
commercially reasonable efforts to timely resolve any regulatory issues that arise in connection with this arrangement, and (y) to the extent reasonably requested by any Investor, the Company has included such Investor or such Investor’s
legal counsel in such a process. 
 3.21 Termination of Covenants. All covenants of the Company and the Investors
contained in Section 3 of this Agreement (other than the provisions of Section 3.4) shall expire and terminate as to each Investor upon the earlier of (i) the effective date of the registration statement pertaining to the Initial
Offering, which results in the Preferred Stock being converted into Common Stock or (ii) upon an Acquisition or Asset Transfer (each as defined in the Company’s Certificate of Incorporation as in effect as of the date hereof ) (a
“Change of Control”). 
 SECTION 4. PREEMPTIVE RIGHTS. 

4.1 Subsequent Offerings. Subject to applicable securities laws, each Participating Investor shall
have the right to purchase its pro rata share of all Equity Securities, as defined below, that the Company may, from time to time, propose to sell and issue after the date of this Agreement, other than the Equity Securities excluded by
Section 4.6 hereof. Each Participating Investor’s pro rata share is equal to the ratio of (a) the total number of outstanding shares of the Company’s Common Stock (including shares of Common Stock that have been issued or
may be issued upon conversion of Shares or other convertible securities which such Participating Investor is deemed to be a holder immediately prior to the issuance of such Equity Securities) to (b) the total number of shares of the
Company’s outstanding Common Stock (including all shares of Common Stock issued or issuable upon conversion of the Shares or upon conversion or exchange of other securities convertible into or exchangeable for Common Stock immediately prior to
the issuance of the Equity Securities). The term “Equity Securities” shall mean (i) any Common Stock, preferred stock or other equity security of the Company, (ii) any security convertible into or exercisable or
exchangeable for, with or without consideration, any Common Stock, preferred stock or other equity security (including any option to purchase such a convertible security), (iii) any security carrying any warrant or right to subscribe to or purchase
any Common Stock, preferred stock or other equity security or (iv) any such warrant or right. 
 4.2
Exercise of Rights. If the Company proposes to issue any Equity Securities, it shall give each Investor written notice of its intention, describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same. Each Investor shall have fifteen (15) days from the giving of such notice to agree to purchase its pro rata share of the Equity Securities for the price not lower and upon the terms and
conditions specified in the notice by giving written notice to the Company and stating therein the quantity of 

  
 - 22 - 








 
Equity Securities to be purchased. Notwithstanding the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Participating Investor who would cause the
Company to be in violation of applicable federal securities laws by virtue of such offer or sale. 
 4.3
Issuance of Equity Securities to Other Persons. If not all of the Participating Investors elect to purchase their pro rata share of the Equity Securities, then the Company shall promptly notify in writing the
Participating Investors who do so elect and shall offer such Participating Investors the right to acquire such unsubscribed shares based on their relative pro rata shares as computed in Section 4.1 hereof. The Participating Investors
shall have ten (10) days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of the unsubscribed shares. If the Participating Investors fail to exercise in full the rights of first refusal,
the Company shall have ninety (90) days thereafter to sell the Equity Securities in respect of which the Participating Investor’s rights were not exercised, at a price and upon general terms and conditions not materially more favorable to
the purchasers thereof than specified in the Company’s notice to the Participating Investors pursuant to Section 4.2 hereof. If the Company has not sold such Equity Securities within ninety (90) days of the notice provided pursuant to

remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement shall impair any such right, power, or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or
