2.1. Restrictions on Transfer. 

(a) Each Holder agrees not to make any disposition of all or any portion of the Preferred Units or 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

is made pursuant to Rule 144; or 
 (iii) (A) The transferee has agreed in writing to be bound by the terms of this Agreement,
(B) 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, provided that no such notice shall be
required in connection if the intended sale, pledge or transfer complies with Rule 144, and (C) 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 not require registration of such units 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 units so transferred do not remain Registrable Securities hereunder following such transfer. 

  
 3 

 (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 a parent corporation
that owns all of the capital stock of the Holder, (C) a limited liability company transferring to its members or former members in accordance with their interest in the limited liability company, (D) an individual transferring to the
Holder’s family member or trust for the benefit of an individual Holder; or (E) a Holder transferring to such Holder’s Affiliates; provided that in each case the transferee will agree in writing to be subject to the terms of this
Agreement to the same extent as if he were an original Holder hereunder. 
 (c) If and to the extent any of the Preferred Units or
Registrable Securities are certificated, each certificate representing such Preferred Units or Registrable Securities, as applicable, shall be stamped or otherwise imprinted with legends 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 (THE “ACT”) AND MAY NOT BE 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 SECURITYHOLDER 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, provided that the 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 this Section 2.2, if the Company shall receive a written request from the Holders of a majority
of the Registrable Securities then outstanding (the “Initiating Holders”) that the Company file a registration statement under the Securities Act covering the registration of at least a majority of
the Registrable Securities then outstanding (or a lesser percent if the anticipated aggregate offering price, net of underwriting discounts and commissions, would exceed $7,500,000), 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. 

  
 4 

 (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 then 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 that would otherwise be underwritten pursuant hereto, and the number of securities 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). 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 fifth anniversary of the date of this Agreement or (B) of the
expiration of the restrictions on transfer set forth in Section 2.11 following the Initial Offering; 
 (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) during the period starting with the date of filing or confidential draft submission of, and ending on the date one hundred
eighty (180) days following the effective date of the registration statement pertaining to the Initial Offering, other than pursuant to a Special Registration Statement; provided that the Company makes reasonable good faith efforts to cause
such registration statement to become effective; 
 (iv) 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 of Managers of the Company (the “Board”) stating that in the good faith judgment of the Board, it would be seriously detrimental to the
Company and its securityholders for such registration statement to be effected at such time because such action would (i) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the
Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act or
Exchange Act, 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; 
 (v) if the Initiating Holders propose to
dispose of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.4 below; or 

  
 5 

 (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 unless already so qualified or consented to. 

2.3. Piggyback Registrations. The Company shall notify all Holders of Registrable Securities in writing at least
twenty (20) days prior to the filing of any registration statement under the Securities Act for purposes of a public offering of securities of the Company (including, but not limited to, registration statements relating to secondary offerings
of securities of the Company, but 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. 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. 
 (a) Underwriting. If the registration statement of 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 in customary form with the underwriter or underwriters selected for such underwriting by the Company; provided, however, that the liability of each Holder
of Registrable Securities in respect of any indemnification, contribution or other obligation of such Holder arising under such underwriting agreement (i) shall be limited to losses arising out of or based upon an untrue statement or alleged
untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement, incorporated document or other such disclosure document or other
document or report, in reliance upon and in conformity with written information furnished to the Company by or on behalf of, and relating to, such Holder expressly for inclusion therein and (ii) shall not in any event exceed an amount equal to
the net proceeds to such Holder (after deduction of all underwriters’ discounts and commissions paid by such Holder) from the disposition of the Registrable Securities disposed of by such Holder pursuant to such registration. Notwithstanding
any other provision of this Agreement, if the Company determines in good faith, based on consultation with the underwriter, that marketing factors require a limitation of the number of securities to be underwritten, the number of securities 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 the Holders; and third, to any securityholder 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 twenty percent (20%) of the total amount of
securities included in such registration, unless such offering is the Initial Offering and such registration does not include securities of any other selling securityholders, in which event any or all of the Registrable Securities of the Holders may
be excluded in accordance with the immediately preceding clause. 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,

  
 6 

 
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 securities 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 whether or not any Holder has elected to include securities in such registration, and shall promptly notify any Holder that has elected to include securities 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 the Holders of Registrable Securities then outstanding a written request or requests that the Company effect a registration on Form S-3 (or any successor to
Form S-3) with respect to at least two million dollars ($2,000,000) of Registrable Securities 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 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 
 (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 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 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 securityholders for such Form S-3 registration to be effected at such time because such action would (i) materially
interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving
as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act or Exchange Act, 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 
 (iv) if the Company has,
within the twelve (12) month period preceding the date of such request, already effected two (2) registrations on Form S-3 for the Holders pursuant to this Section 2.4, or 

  
 7 

 (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 unless already so qualified or consented to. 

(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, 2.3 or 2.4 herein shall be borne 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 securities 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) or 2.4(b)(v), as applicable, 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 securities 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) or
2.4(b)(v), as applicable, 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 all 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 up to thirty (30) 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. If so directed by the Company, all Holders registering securities 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 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

  
 8 

 
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 its 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 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 its 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 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. 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 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
the number of securities or the anticipated aggregate offering price of the Registrable Securities to be included in the registration does not equal or exceed the number of securities 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. 

2.8. 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, legal
counsel, accountants, officers and directors of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls or is alleged to control 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 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, legal counsel, accountant, officer, director, underwriter or controlling 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; provided however, that the indemnity agreement contained in this Section 2.8(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 or on behalf of, and relating to, such Holder, partner, member, legal counsel, accountant,
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 

  
 10 

 
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 of the following statements: (i) any untrue statement or alleged untrue statement of a material fact contained in such registration
statement or incorporated 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 (collectively, a “Holder Violation”), in each case to the
extent (and only to the extent) that such Holder Violation occurs in reliance upon and in conformity with written information furnished by or on behalf of, and relating to, such Holder under an instrument duly executed by such Holder and stated to
be specifically for use in connection with such registration; 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 2.8(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 2.8 exceed the net proceeds from the offering received by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 2.8 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 2.8, 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 thereof to be paid by the indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such action shall relieve such indemnifying party of any liability to the indemnified party under this Section 2.8 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 2.8. 

(d) If the indemnification provided for in this Section 2.8 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. 

  
 11 

 (e) The obligations of the Company and Holders under this Section 2.8 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 2.8 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. 

2.9. 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 a transferee or assignee of Registrable Securities (for so long as such securities remain Registrable Securities) that (a) is a subsidiary, parent, general
partner, limited partner, retired partner, member or retired member, or stockholder of a Holder that is a corporation, partnership or limited liability company, (b) is a Holder’s family member or trust for the benefit of an individual
Holder, or (c) acquires at least one hundred thousand (100,000) Registrable Securities (as adjusted for unit splits and combinations); or (d) is an Affiliate of such Holder; 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. 
 2.10. Limitation on Subsequent
Registration Rights. Other than as provided in Section 5.10, after the date of this Agreement, the Company shall not enter into any agreement with any holder or prospective holder of any securities of the Company that would grant such
holder rights to demand the registration of securities of the Company, or to include such securities in a registration statement that would reduce the number of securities includable by the Holders. 

2.11. Market Stand-Off Agreement. Each Holder hereby agrees that, during the Standoff
Period, such Holder shall not, without the prior written consent of the Company or the managing underwriter, 
 (a) lend, offer,
pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right, or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, any Common Units of the
Company, or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Units of the Company, held immediately before the effective date of the registration statement for such offering; or 

(b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of
ownership of such securities, whether any such transaction described in clause (a) above is to be settled by delivery of Common Units of the Company or other securities, in cash, or otherwise. 

The foregoing provisions of this Section 2.11 shall not apply to the sale of any securities of the Company to an underwriter pursuant to an underwriting
agreement, and shall be applicable to the Holders only if all officers, directors, and securityholders individually owning more than one percent (1%) of the Company’s voting securities (after giving effect to conversion into Common Units of all
outstanding Preferred Units) are similarly bound. For purposes of this Section 2.11 and Section 2.12, the term “Company” shall include any wholly-owned subsidiary of the Company into which the Company merges or consolidates. In
order to enforce the covenants in this Section 2.11, the Company shall have the right to place restrictive legends on the certificates representing the securities of the Company subject to these Sections and to impose stop transfer instructions
with respect to such securities until the end of such period. The underwriters in connection with such registration are intended third-party beneficiaries of Section 2.11 and Section 2.12 

  
 12 

 
hereof and shall have the right, power, and authority to enforce the provisions hereof as though they were a party hereto. Each Holder further agrees to execute such agreements as may be
reasonably requested by the underwriters in connection with such registration that are consistent with this Section 2.11 and Section 2.12 or that are necessary to give further effect thereto. Any discretionary waiver or termination of the
restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Holders subject to such agreements, based on the number of units subject to such agreements. Each Holder agrees that any transferee of any
Registrable Securities shall be bound by Sections 2.11 and 2.12 hereof. 
 2.12. Agreement to Furnish Information. If
reasonably requested by the Company or the representative of the underwriters of securities of the Company, each Holder participating in the offering shall provide, within ten (10) days of such request, such information as may be legally
required 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 2.11 and this Section 2.12 shall not apply to a
Special Registration Statement. 
 2.13. 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 to 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. 
 2.14. Termination of Registration Rights. The right of any Holder to request registration or inclusion of
Registrable Securities in any registration pursuant to Section 2.2, Section 2.3, or Section 2.4 hereof shall terminate upon the earlier of (i) the date three (3) years following an initial public offering that results in the
conversion of all outstanding Preferred Units, or (ii) such time as the Company has completed its Initial Offering and all Registrable Securities of the Company issuable or issued upon conversion of the Preferred Units held by and issuable to
such Holder (and its Affiliates) may be sold pursuant to Rule 144 during any ninety (90) day period. Upon such termination, such securities shall cease to be “Registrable Securities” hereunder for all purposes.

3.2. Inspection Rights. Each Major Investor shall have the right to visit and inspect any of the properties of the
Company or any of its subsidiaries, and to discuss the affairs, finances and accounts of the Company or any of its subsidiaries with its officers, and to review such information as is reasonably requested all at such reasonable times and as often as
may be reasonably requested; provided, however, that the Company shall not be obligated under Section 3.1 or this Section 3.2 with respect to a competitor of the Company or with respect to information which the Board
determines in good faith is highly confidential, a trade secret or attorney-client privileged and should not, therefore, be disclosed; provided, further, that Sands Capital Private Growth Fund III, L.P., Sands Capital Private Growth Fund III-DC, L.P.

of the Company for any purpose under this Agreement. 
 3.3. Confidentiality of Records. Each Investor agrees 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 of such Investor’s attorneys, accountants and other advisors in
connection with their services and advice related to the same, and to any existing or prospective partner, limited partner, Affiliate, subsidiary or parent of such Investor as long as such partner, limited partner, Affiliate, 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. 
 3.4. Reservation of Common Units. The Company will at all times
reserve and keep available, solely for issuance and delivery upon the conversion of the Preferred Units, all Common Units issuable from time to time upon such conversion. 

3.5. Proprietary Information and Inventions Agreement. The Company shall require all employees and consultants to execute and
deliver a Proprietary Information and Inventions Agreement substantially in a form approved by the Company’s counsel or the Board. 

3.6. Directors’ Liability, Indemnification and Insurance. The Company’s limited liability company
agreement then in effect (the “LLC Agreement”) shall provide (a) for elimination 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. The Company shall use commercially reasonable efforts to maintain, from financially sound and reputable insurers, Directors and Officers liability insurance in an amount and on terms and conditions
satisfactory to the Board, until such time as the Board determines that such insurance should be discontinued

incurred (consistent with the Company’s travel policy) in connection with attending meetings of the Board and for other meetings or events attended at the request of the Company. 

3.8. Successor Indemnification. If the Company or any of its successors or assignees consolidates with or merges
into any other Person and is not the continuing or surviving corporation or entity of such consolidation or merger, then to the extent necessary, proper provision shall be made so that the successors and assignees of the Company assume the
obligations of the Company with respect to indemnification of members of the Board of Managers as in effect immediately before such transaction, whether such obligations are contained in the LLC Agreement, or elsewhere, as the case may be. 

3.9. Employee Equity. Unless otherwise approved by the Board of Managers, all future employees of the Company who purchase,
receive options to purchase, or receive awards of the Company’s Units after the date hereof shall be required to execute agreements, as applicable, providing for (i) vesting of the Units over a four (4) year period, with the first
twenty-five percent (25%) of such Units vesting 

  
 15 

 
following twelve (12) months of continued employment or service, and the remaining shares vesting in equal monthly installments over the following
thirty-six (36) months, and (ii) a market stand-off provision substantially similar to that in Section 2.11. Without the prior approval by the Board of
Managers, the Company shall not amend, modify, terminate, waive or otherwise alter, in whole or in part, any unit purchase, grant or profits interest agreement with any existing employee or service provider if such amendment would cause it to be
inconsistent with this Section 3.9. In addition, unless otherwise approved by the Board of Managers, the Company (x) shall not offer or allow any acceleration of vesting, and (y) shall retain (and not waive) a “right of first
refusal” on employee transfers until the Company’s Initial Offering. 
 3.10. Right to Conduct Activities. The
Company hereby agrees and acknowledges that each Fund Investor (together with its respective Affiliates) is a professional investment organization, and as such reviews the business plans and related proprietary information of many enterprises, some
of which may compete directly or indirectly with the Company’s business (as currently conducted or as currently propose to be conducted). Nothing in this Agreement shall preclude or in any way restrict the Investors from evaluating or
purchasing securities, including publicly traded securities, of a particular enterprise, or investing or participating in any particular enterprise whether or not such enterprise has products or services which compete with those of the Company; and
the Company hereby agrees that, to the extent permitted under applicable law, no Fund Investor (nor its respective Affiliates) shall be liable to the Company for any claim arising out of, or based upon, (i) the investment by such Fund Investor
(or any of such Fund Investor’s Affiliates) in any entity competitive with the Company, or (ii) actions taken by any partner, officer, employee or other representative of such Fund Investor (or its Affiliates) to assist any such
competitive company, whether or not such action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided, however, that
the foregoing shall not relieve (x) any of the Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained pursuant to this Agreement, or (y) any Manager or officer of the
Company from any liability associated with his or her fiduciary duties to the Company. 
 3.11. Anti-Harassment Policy. The
Company shall maintain in effect (i) a Code of Conduct governing appropriate workplace behavior and (ii) an Anti-Harassment and Discrimination Policy prohibiting discrimination and harassment at the Company. Such policy shall be reviewed
and approved by the Board of Managers. 
 3.12. FCPA. The Company covenants that it shall not (and shall not permit any of its
subsidiaries or Affiliates or any of its or their respective directors, officers, managers, employees, independent contractors, representatives or agents to) promise, authorize or make any payment to, or otherwise contribute any item of value to,
directly or indirectly, to any third party, including any Non-U.S. Official (as such term is defined in the U.S. Foreign Corrupt Practices Act of 1977, as amended (the “FCPA”)), in each
case, in violation of the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. The Company further covenants that it shall (and shall cause each of its subsidiaries and Affiliates to) cease all of its or their
respective activities, as well as remediate any actions taken by the Company, its subsidiaries or Affiliates, or any of their respective directors, officers, managers, employees, independent contractors, representatives or agents in violation of the
FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. The Company further covenants that it shall use commercially reasonable efforts to (and shall take commercially reasonable efforts to cause each of its
subsidiaries and Affiliates to) maintain systems of internal controls (including, but not limited to, accounting systems, purchasing systems and billing systems) that are customary and appropriate for companies similarly situated to the Company to
ensure compliance with the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. 

  
 16 

 3.13. Cybersecurity. The Company shall, within one hundred eighty
(180) days following the Initial Closing (as defined in the Purchase Agreement), use commercially reasonable efforts to (a) identify and restrict access (including through physical and/or technical controls) to the Company’s
confidential business information and trade secrets and any information about identified or identifiable natural persons maintained by or on behalf of the Company (collectively, “Protected Data”)
to those individuals who have a need to access it and (b) implement reasonable physical, technical and administrative safeguards designed to protect the confidentiality, integrity and availability of its technology and systems (including
servers, laptops, desktops, cloud, containers, virtual environments and data centers) and all Protected Data. The Company shall evaluate on a periodic basis at least annually whether such safeguards should be updated to maintain a level of security
appropriate to the risk posed to Company systems and Protected Data. The Company shall educate its employees about the proper use and storage of Protected Data, including periodic training as determined reasonably necessary by the Company or the
Board of Managers. 
 3.14. Expenses of Counsel. In the event of a Deemed Liquidation Event (as
defined in the LLC Agreement), the reasonable fees and disbursements, not to exceed $50,000, of one counsel for the Major Investors (“Investor Counsel”), in their capacities as members, shall be borne and paid by the Company.
At the outset of considering a transaction which, if consummated would constitute a Deemed Liquidation Event, the Company shall obtain the ability to share with the Investor Counsel (and such counsel’s clients) and shall share the confidential
information (including, without limitation, the initial and all subsequent drafts of memoranda of understanding, letters of intent and other transaction documents and related noncompete, employment, consulting and other compensation agreements and
plans) pertaining to and memorializing any of the transactions which, individually or when aggregated with others would constitute the Deemed Liquidation Event. The Company shall be obligated to share (and cause the Company’s counsel and
investment bankers to share) such materials when distributed to the Company’s executives and/or any one (1) or more of the other parties to such transaction(s). In the event that Investor Counsel deems it appropriate, in its reasonable
discretion, to enter into a joint defense (or common interest) agreement or other arrangement to enhance the ability of the parties to protect their communications and other reviewed materials under the attorney client privilege, the Company shall,
and shall direct its counsel to, execute and deliver to Investor Counsel and its clients such an agreement in form and substance reasonably acceptable to Investor Counsel and the Company’s counsel. In the event that one (1) or more of the
other party or parties to such transactions require the clients of Investor Counsel to enter into a confidentiality agreement and/or joint defense (or common interest) agreement in order to receive such information, then the Company shall share
whatever information can be shared without entry into such agreement and shall, at the same time, in good faith work expeditiously to enable Investor Counsel and its clients to negotiate and enter into the appropriate agreement(s) without undue
burden to the clients of Investor Counsel. 
 3.15. Termination of Covenants. All covenants of the Company contained in
Section 3 of this Agreement (other than the provisions of Section 3.3, 3.6 and 3.8) shall expire and terminate as to each Investor upon the earlier of (i) the effective date of the registration statement pertaining to an Initial
Offering that results in the Preferred Units being converted into Common Units or (ii) upon an “Acquisition” as defined in the LLC Agreement as in effect as of the date hereof. 

SECTION 4. RIGHTS OF FIRST REFUSAL. 

4.1. Subsequent Offerings. Subject to applicable securities laws, each Major Investor shall have a right of first refusal 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 Investor’s pro rata share is equal to the ratio of (a) the number of the Company’s Common Units (including all Common Units issuable or issued upon conversion of the Preferred Units or upon the
exercise of outstanding warrants, options or any other securities or rights convertible into, or exercisable or exchangeable for (in each case, directly or indirectly) 

  
 17 

 
Common Units) of which such Investor is deemed to be a holder immediately prior to the issuance of such Equity Securities to (b) the total number of the Company’s outstanding Common
Units (including all Common Units issued or issuable upon conversion of the Preferred Units or upon the exercise of any outstanding warrants, options or any other securities or rights convertible into, or exercisable or exchangeable for (in each
case, directly or indirectly) Common Units)) immediately prior to the issuance of the Equity Securities. The term “Equity Securities” shall mean (i) any Common Units, Preferred Units or other security of the Company,
(ii) any security convertible into or exercisable or exchangeable for, with or without consideration, any Common Units, Preferred Units or other 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 Units, Preferred Units or other 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 Major 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 Major 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 and upon the terms and conditions specified in the notice by giving written notice to the Company and stating therein the quantity of Equity Securities to be purchased. Notwithstanding
the foregoing, the Company shall not be required to offer or sell such Equity Securities to any Major 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 Major Investors elect to purchase their pro rata share of the Equity Securities, then the Company shall promptly notify in writing the Major Investors who do so elect and shall offer such Major Investors
the right to acquire such unsubscribed Equity Securities on a pro rata basis. The Major Investors shall have five (5) days after receipt of such notice to notify the Company of its election to purchase all or a portion thereof of the
unsubscribed Equity Securities. The Company shall have ninety (90) days thereafter to sell the Equity Securities in respect of which the Major Investor’s rights were not exercised, at a price not lower and upon general terms and conditions
not materially more favorable to the purchasers thereof than specified in the Company’s notice to the Major 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 Section 4.2, the Company shall not thereafter issue or sell any Equity Securities, without first offering such Equity Securities to the Major Investors in the manner provided above. 

4.4. Termination and Waiver of Rights of
First Refusal. The rights of first refusal established by this Section 4 shall not apply to, and shall terminate upon the earlier of (i) the effective date of the registration statement pertaining to the
Company’s Initial Offering or (ii) an Acquisition. Notwithstanding Section 5.5 hereof, the rights of first refusal established by this Section 4 may be amended, or any provision waived with and only with the written consent of
the Company and the Major Investors holding a majority of the Registrable Securities then held by all Major Investors or as permitted by Section 5.5. 

4.5. Assignment of Rights of First Refusal. The rights of first refusal of each Major Investor under this Section 4 may be
assigned to the same parties, subject to the same restrictions as any transfer of registration rights pursuant to Section 2.9. 

4.6. Excluded Securities. The rights of first refusal established by this Section 4 shall have no application to (a) any of the
securities excluded from the definition of “Additional Common Units” as set forth in Exhibit B of the LLC Agreement or (b) any Series C-1 Preferred Units issued pursuant to
Section 2 of the Purchase Agreement. 

  
 18 

 SECTION 5. MISCELLANEOUS. 

5.1. Governing Law. This Agreement shall be governed by and construed under the laws of the State of California in all respects
as such laws are applied to agreements among California residents entered into and to be performed entirely within California, without reference to conflicts of laws or principles thereof. 

5.2. Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of,
and be binding upon, the parties hereto and their respective successors, assigns, heirs, executors, and administrators and shall inure to the benefit of and be enforceable by each person who shall be a holder of Registrable Securities from time to
time; provided, however, that prior to the receipt by the Company of adequate written notice of the transfer of any Registrable Securities specifying the full name and address of the transferee, the Company may deem and treat the
person listed as the holder of such securities in its records as the absolute owner and holder of such securities for all purposes, including the payment of dividends or any redemption price. 

5.3. Entire Agreement. This Agreement, the Exhibits and Schedules hereto, the LLC Agreement, the Purchase
Agreement and the other documents delivered pursuant thereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable or bound to any other in any manner by any
oral or written representations, warranties, covenants and agreements (including the Prior Agreement) except as specifically set forth herein and 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. 
 5.4. Severability. In the event one or more
of the provisions of this Agreement should, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provisions of this Agreement, and this Agreement
shall be construed as if such invalid, illegal or unenforceable provision had never been contained herein. 
 5.5. Amendment and Waiver.

 (a) Except as otherwise expressly provided herein, this Agreement may be amended or modified, and the obligations of the
Company and the rights of the Holders under this Agreement may be waived, only upon the written consent of the Company and (a) with respect to Sections 3 and 4 and any other provision of this Agreement to the extent such provision pertains to
Section 3 or 4, the Major Investors who own at least a majority of the Units then owned by Major Investors or (b) with respect to Section 2 and any other provision of this Agreement to the extent such provision pertains to
Section 2, the holders of at least a majority of the then-outstanding Registrable Securities, which majority must include the Requisite Series C Holders (as defined in the LLC Agreement). Any amendment or waiver effected in accordance with this
paragraph shall be binding upon each party to the Agreement, whether or not such party has signed such amendment or waiver, each future holder of all such Registrable Securities and the Company. Notwithstanding the foregoing, this Agreement may not
be amended, modified or terminated and the observance of any term hereunder may not be waived with respect to any Investor without the written consent of such Investor, if such amendment, modification, termination or waiver would alter or change the
rights or obligations of such Investor so as to affect such Investor in an adverse manner without similarly and proportionally affecting the rights and obligations of the other Investors under this Agreement. 

(b) For the purposes of determining the number of Holders or Investors entitled to vote or exercise any rights hereunder, the Company
shall be entitled to reasonably rely on the list of record holders of its securities as maintained by or on behalf of the Company. 

  
 19 

 5.6. Delays or Omissions. It is agreed that no delay or omission to exercise
any right, power, or 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 any acquiescence therein, or of any similar breach, default or noncompliance thereafter occurring. It is further agreed that any waiver, permit, consent, or approval of any kind or character on any party’s part of any breach,
default or noncompliance under the Agreement or any waiver on such party’s part 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, by law, or otherwise afforded to any party, shall be cumulative and not alternative. 
 5.7.
Notices. All notices required or permitted hereunder shall be in writing and shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) upon confirmation of receipt when sent by confirmed
electronic mail or facsimile if sent during normal business hours of the recipient; if not, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or

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. 

5.9. Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only
and are not to be considered in construing this Agreement.

contrary contained herein, if the Company shall issue additional Preferred Units after the date hereof, any purchaser of such Preferred Units may become a party to this Agreement by executing and delivering an additional counterpart signature page
to this Agreement and upon doing so shall be deemed an “Investor,” a “Holder” and a party hereunder. No action or consent by the Investors shall be required for such joinder to this Agreement by such
additional Investor, so long as such additional Investor has agreed in writing to be bound by all of the obligations as an “Investor” hereunder. 

5.11. Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of
which together shall constitute one instrument. Counterparts may be delivered via electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission method and

arising out of or based upon this Agreement (an “Agreement Dispute”) except in the federal or state courts located in the Northern District of California, (b) hereby irrevocably and
unconditionally submits to the jurisdiction of the federal or state courts located in the Northern District of California for the purpose of any such Agreement Dispute, and (c) hereby waives, and agrees not to assert, by way of motion, as a
defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or
proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement, or the subject matter hereof and thereof may not be enforced in or by such court. 

5.16. Amendment of Prior Agreement. Pursuant to Section 5.5 of the Prior Agreement, effective and contingent upon execution
of this Agreement by the Company, the holders of a majority of the Registrable Securities then outstanding, which majority shall include the Requisite Series C Holders (as defined in the LLC Agreement), and the Major Investors who own at least a

Award grants to whom shall be determined by the compensation committee of the Board, or before the appointment of compensation committee,
by the Board);

 

		(iv)	to approve forms of agreement for use under the Plan;

 

		(v)	to determine the terms and conditions, of any Awards granted hereunder. Such terms and conditions include, but are not limited to,
the exercise price (where applicable), the time or times when an Award may be exercised (which may be based on performance criteria or
a pre-determined vesting period), any forfeiture restrictions, any vesting acceleration or waiver of forfeiture restrictions, and any
restriction or limitation regarding any Awards or the Ordinary Shares relating thereto, based in each case on such factors as the Administrative

		(vi)	to determine whether and under what circumstances an Option may be settled in cash under subsection 9(e) below instead of Ordinary

		(viii)	to prescribe, amend and rescind rules and regulations relating to the Plan (but not the Plan per se), including rules and regulations

		(ix)	to allow Grantees to satisfy withholding tax obligations by electing to have the Company withhold from the Ordinary Shares to be issued
upon exercise of or in relation to an Award that number of Ordinary Shares having a Fair Market Value equal to the amount required to
be withheld. The Fair Market Value of the Ordinary Shares to be withheld shall be determined on the date that the amount of tax to be
withheld is to be determined or the tax liability arises or the tax is due to be paid, or any other date as the Administrative Committee
may deem appropriate. All elections by Grantees to have Ordinary Shares withheld for this purpose shall be made in such form and under
such conditions as the Administrative Committee may deem necessary or advisable;

 

     

     

    

 

Page 6

All decisions, determinations and interpretations of the Administrative
Committee pursuant to the provisions of the Plan shall be final conclusive and binding on all Grantees.

 

		5.	Eligibility

 

		(a)	Awards may be granted to Service Providers.

 

		(b)	Neither the Plan nor any Awards shall confer upon any Grantee any right with respect to continuing the Grantee’s relationship
as a Service Provider with the Company, nor shall it interfere in any way with his or her right or the Company’s right to terminate
such relationship at any time, with or without cause.

 

		6.	Term of Plan

 

The Plan shall become effective on August 27, 2021, upon
its adoption by the Board. It shall continue in effect for a term of twenty (20) years unless sooner terminated under Section 16 below.

 

		7.	Term of Award

 

The term of each Award shall be stated in the Award Agreement.

 

		8.	Option Exercise Price and Consideration

 

		(a)	The per share exercise price for the Ordinary Shares to be issued upon exercise of an Option shall be such price as is determined
by the Administrative Committee.

 

		(b)	The terms, conditions and restrictions for the issuance of the Ordinary Shares upon exercise of an Option, including the method of
payment, shall be determined by the Administrative Committee. The Administrative Committee may at its sole discretion authorize or accept
payment in one or more of the following manners:

 

		(i)	cash,

 

		(ii)	check payable to the order of the Company,

 

		(iii)	promissory note,

 

		(iv)	surrender to the Company of other Ordinary Shares which (x) in the case of Ordinary Shares acquired upon exercise of an Option, have
been owned by the Grantee for more than six (6) months on the date of surrender, and (y) have a Fair Market Value on the date of surrender
equal to the aggregate exercise price of the Ordinary Shares as to which such Option shall be exercised,

 

     

     

    

 

Page 7

 

		(v)	consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan, or

 

		(vi)	any combination of the foregoing methods of payment.

 

In making its determination as to the above, the Administrative
Committee shall consider the best interest of and advantage to the Company.

 

		9.	Exercise of Option

 

		(a)	Procedure for Exercise; Rights as a Shareholder

 

Any Option granted hereunder shall be exercisable according
to the terms hereof at such times and under such conditions as determined by the Administrative Committee and set forth in the Award Agreement.
An Option may not be exercised for a fraction of an Ordinary Share.

 

An Option shall be deemed exercised when the Company receives:

 

		(i)	written or electronic notice of exercise (in accordance with the Award Agreement) from the person entitled to exercise the Option,
and

 

		(ii)	full payment for the Ordinary Shares with respect to which the Option is exercised.

 

Full payment may consist of any consideration and method of
payment authorized by the Administrative Committee and permitted by the Award Agreement and the Plan. After the Option is exercised, the
Company shall promptly issue (or cause to be issued) such number of Ordinary Shares as covered by such Option. Ordinary Shares issued
upon exercise of an Option shall be issued in the name of the Grantee or, if requested by the Grantee, in the joint name of the Grantee
and his or her spouse. Until the Ordinary Shares are issued (as evidenced by the appropriate entry on the books of the Company or of a
duly authorized transfer agent of the Company), no right to attend general meeting of the Company, vote or receive dividends or other
distributions or any other rights as a shareholder shall exist with respect to the Ordinary Shares, notwithstanding the exercise of the
Option. No adjustment will be made for a dividend or other right for which the record date is prior to the date the Ordinary Shares are
issued, except as provided in Section 14 below.

 

Exercise of an Option in any manner shall result in a decrease
in the number of Ordinary Shares thereafter available, both for purposes of the Plan and for sale under the Option, by the number of Ordinary
Shares as to which the Option is exercised.

 

		(b)	Termination of Relationship as Service Provider

 

If a Grantee ceases to be a Service Provider (save and except
due to the Grantee’s Disability, in which event subsection 9(c) below shall apply or due to the Grantee’s death, in which
event subsection 9(d) below shall apply), such Grantee may exercise his or her Option within such period of time as is specified in the
Award Agreement (of at least thirty (30) days but in no event later than the expiration of the term of the Option as set forth in the
Award Agreement) to the extent that the Option is vested on the date of such cessation . In the absence of a specified time in the Award
Agreement, the Option shall remain exercisable for three (3) months following the Grantee’s cessation as aforesaid (but in no event
later than the expiration of the term of the Option as set forth in the Award Agreement). If, on the date of cessation, the Grantee is
not vested as to his or her entire Option, the Ordinary Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after the cessation, the Grantee does not exercise his or her Option to the fullest extent vested within the time specified in the
Award Agreement or stipulated herein as the case may be, the Option shall lapse automatically, and the Ordinary Shares covered by such
unexercised portion of the Option shall revert to the Plan and the Grantee shall have no claim for compensation or otherwise against the
Company whatsoever.

 

     

     

    

 

Page 8

 

		(c)	Disability of Grantee

 

If a Grantee ceases to be a Service Provider as a result of
the Grantee’s Disability, the Grantee may exercise his or her Option within such period of time as is specified in the Award Agreement
(of at least six (6) months but in no event later than the expiration of the term of such Option as set forth in the Award Agreement)
to the extent the Option is vested on the date of such cessation. In the absence of a specified time in the Award Agreement, the Option
shall remain exercisable for twelve (12) months following the Grantee’s cessation as aforesaid (but in no event later than the expiration
of the term of such Option as set forth in the Award Agreement). If, on the date of cessation, the Grantee is not vested as to his or
her entire Option, the Ordinary Shares covered by the unvested portion of the Option shall revert to the Plan. If, after the cessation,
the Grantee does not exercise his or her Option to the fullest extent vested within the time specified in the Award Agreement or stipulated
herein as the case may be, the Option shall lapse automatically, and the Ordinary Shares covered by such unexercised portion of the Option
shall revert to the Plan and the Grantee shall have no claim for compensation or otherwise against the Company whatsoever.

 

		(d)	Death of Grantee

 

If a Grantee dies while being a Service Provider, the Option
may be exercised within such period of time as is specified in the Award Agreement (of at least six (6) months but in no event later than
the expiration of the term of such Option as set forth in the Award Agreement) to the extent that the Option is vested on the date of
death by the Grantee’s estate or by a person who acquires the right to exercise the Option by bequest or inheritance (collectively,
the “Grantee’s Representative”). In the absence of a specified time in the Award Agreement, the Option shall remain
exercisable for twelve (12) months following the Grantee’s death (but in no event later than the expiration of the term of such
Option as set forth in the Award Agreement). If, at the time of death, the Grantee is not vested as to the entire Option, the Ordinary
Shares covered by the unvested portion of the Option shall immediately revert to the Plan. If the Option is not exercised by the Grantee’s
Representative to the fullest extent vested within the time specified in the Award Agreement or stipulated herein as the case may be,
the Option shall lapse automatically, and the Ordinary Shares covered by such unexercised portion of the Option shall revert to the Plan
and the Grantee’s estate and the Grantee’s Representative shall have no claim for compensation or otherwise against the Company
whatsoever.

		(e)	Buyout Provisions

 

The Administrative Committee may at any time offer to buy out
an Option previously granted for a payment in cash or Ordinary Shares, based on such fair and reasonable terms and conditions as the Administrative
Committee shall establish and communicate to the Grantee at the time that such offer is made or as set forth in the Award Agreement.

 

		10.	Stock Purchase Rights

 

		(a)	Rights to Purchase

 

Stock Purchase Rights may be issued in favor of the Grantees
either alone, in addition to, or in tandem with other awards granted under the Plan and/or cash awards made by the Company outside of
the Plan. After the Administrative Committee determines that it will offer Stock Purchase Rights under the Plan, it shall advise the offeree
in writing or electronically of the terms, conditions and restrictions related to the offer, including the number of Ordinary Shares that
such person shall be entitled to purchase, the price to be paid, the forfeiture restrictions, the time limit for the exercise of the Stock
Purchase Rights and the time within which such person must accept such offer.

 

		(b)	Repurchase Option

 

Unless the Administrative Committee determines otherwise, the
Award Agreement shall grant the Company a repurchase option exercisable upon the voluntary or involuntary termination of the Grantee as
a Service Provider for any reason (including death or Disability). The purchase price for Ordinary Shares repurchased pursuant to the
Award Agreement shall be the original price paid by the Grantee and may be paid by cancellation of any indebtedness of the Grantee to
the Company.

 

(c)        Other Provisions

 

The Award Agreement shall contain such other terms, provisions
and conditions not inconsistent with the Plan as may be determined by the Administrative Committee at its sole discretion.

 

(d)        Rights as
a Shareholder

 

Once the Stock Purchase Right is exercised, the purchaser shall
have rights equivalent to those of a shareholder and shall be a shareholder when his or her purchase and personal particulars are entered
upon the records of the Company or of the duly authorized transfer agent of the Company. No adjustment shall be made for a dividend or
other right for which the record date is prior to the date the Stock Purchase Right is exercised, except as provided in Section 14 below.

		11.	Restricted Shares

 

		(a)	Grant of Restricted Shares

 

The Administrative Committee, at any time and from time to
time, may grant Restricted Shares to Service Providers as the Administrative Committee, in its sole discretion, shall determine. The Administrative
Committee, in its sole discretion, shall determine the number of Restricted Shares to be granted to each Service Provider.

 

		(b)	Award Agreement

 

Each award of Restricted Shares shall be evidenced by an Award
Agreement that shall specify the period of restriction, the number of Restricted Shares granted, and such other terms and conditions as
the Administrative Committee, in its sole discretion, shall determine. Unless the Administrative Committee determines otherwise, Restricted
Shares shall be held by the Company as escrow agent until the restrictions on such Restricted Shares have lapsed.

 

		(c)	Issuance and Restrictions

 

Restricted Shares shall be subject to such restrictions on
transferability and other restrictions as the Administrative Committee may impose (including, without limitation, limitations on the right
to vote Restricted Shares or the right to receive dividends on the Restricted Share). These restrictions may lapse separately or in combination
at such times, pursuant to such circumstances, in such installments, or otherwise, as the Administrative Committee determines at the time
of the grant of the Restricted Shares or thereafter.

 

		(d)	Forfeiture/Repurchase

 

Except as otherwise determined by the Administrative Committee
at the time of the grant of the Restricted Shares or thereafter, upon termination of employment or service during the applicable restriction
period, Restricted Shares that are at that time subject to restrictions shall be forfeited or repurchased in accordance with the Award
Agreement; provided, however, the Administrative Committee may (i) provide in any Award Agreement that restrictions or forfeiture and
repurchase conditions relating to Restricted Shares will be waived in whole or in part in the event of terminations resulting from specified
causes, and (ii) in other cases waive in whole or in part restrictions or forfeiture and repurchase conditions relating to Restricted
Shares.

 

		(e)	Certificates for Restricted Shares

 

Restricted Shares granted pursuant to the Plan may be evidenced
in such manner as the Administrative Committee shall determine. If certificates representing Restricted Shares are registered in the name
of the Service Provider, certificates must bear an appropriate legend referring to the terms, conditions, and restrictions applicable
to such Restricted Shares, and the Company may, at its discretion, retain physical possession of the certificate until such time as all
applicable restrictions lapse.

 

     

     

    

 

Page 11

 

		(f)	Removal of Restrictions

 

Except as otherwise provided in this Section 11, Restricted
Shares granted under the Plan shall be released from escrow as soon as practicable after the last day of the period of restriction. The
Administrative Committee, in its discretion, may accelerate the time at which any restrictions shall lapse or be removed. After the restrictions
have lapsed, the Service Provider shall be entitled to have any legend or legends under Subsection 11(e) removed from his or her certificate
for Restricted Shares, and the underlying Ordinary Shares shall be freely transferable by the Service Provider, subject to applicable
legal restrictions. The Committee (in its discretion) may establish procedures regarding the release of the underlying Ordinary Shares
from escrow and the removal of legends, as necessary or appropriate to minimize administrative burdens on the Company.

 

		12.	Restricted Share Units

 

		(a)	Grant of Restricted Share Units

 

The Administrative Committee, at any time and from time to
time, may grant Restricted Share Units to Service Providers as the Administrative Committee, in its sole discretion, shall determine.
The Administrative Committee, in its sole discretion, shall determine the number of Restricted Share Units to be granted to each Service
Provider.

 

		(b)	Award Agreement

 

Each award of Restricted Share Units shall be evidenced by
an Award Agreement that shall specify any vesting conditions, the number of Restricted Share Units granted, and such other terms and conditions
as the Administrative Committee, in its sole discretion, shall determine.

 

		(c)	Performance Objectives and Other Terms

 

The Administrative Committee, in its discretion, may set performance
objectives or other vesting criteria which, depending on the extent to which they are met, will determine the number or value of Restricted
Share Units that will be paid out to the Service Providers.

 

		(d)	Form and Timing of Payment of Restricted Share Units

 

At the time of grant, the Administrative Committee shall specify
the date or dates on which the Restricted Share Units shall become fully vested and nonforfeitable. Upon vesting, the Administrative Committee,
in its sole discretion, may pay Restricted Share Units in the form of cash, in Ordinary Shares or in a combination thereof.

 

		(e)	Forfeiture/Repurchase

 

Except as otherwise determined by the Administrative Committee
at the time of the grant of the Restricted Share Units or thereafter, upon termination of employment or service during the applicable
restriction period, Restricted Share Units that are at that time unvested shall be forfeited or repurchased in accordance with the Award
Agreement; provided, however, the Administrative Committee may (i) provide in any Award Agreement that restrictions or forfeiture and
repurchase conditions relating to Restricted Share Units will be waived in whole or in part in the event of terminations resulting from
specified causes, and (ii) in other cases waive in whole or in part restrictions or forfeiture and repurchase conditions relating to Restricted
Share Units.

		13.	Non-Transferability of Awards

 

The Awards may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of succession and may be exercised, during the lifetime of
the Grantee, only by the Grantee except as provided in subsection 9(d) above.

 

		14.	Adjustments Upon Changes in Capitalization, Merger or Asset Sale

 

		(a)	(i)Changes in Capitalization

 

Subject to any action of the shareholders of the Company
as necessitated by the Applicable Laws, the number of Ordinary Shares covered by each outstanding Award and the number of Ordinary Shares
which have been authorized for issuance under the Plan but as to which no Awards have yet been granted or which have been reverted to
the Plan upon cancellation or expiration of an Award as well as the price per Ordinary Share covered by each such outstanding Award shall
be proportionately adjusted for any increase or decrease in the number of issued Ordinary Shares effected without receipt of consideration
by the Company. The conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt
of consideration”. Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Ordinary
Shares subject to an Award.

 

		(ii)	Adjustments for Stock Split, Stock Dividend, Etc.

 

If the Company shall at any time increase or decrease the
number of its outstanding Ordinary Shares, or change in any way the rights and privileges of its outstanding Ordinary Shares, by means
of the payment of a stock dividend or any other distribution upon such Ordinary Shares, or through a stock split, subdivision, consolidation,
combination, reclassification or recapitalization involving such Ordinary Shares, then in relation to the Ordinary Shares that are covered
by the Awards granted or available under the Plan and are affected by one or more of the above events, the numbers, rights and privileges
of the following shall be increased, decreased or changed in like manner as if such Ordinary Shares had been issued and outstanding, fully
paid and non-assessable at the time of such occurrence.

 

		(b)	Dissolution or Liquidation

 

In the event of the proposed dissolution or liquidation of
the Company, the Administrative Committee shall notify each Grantee as soon as practicable prior to the effective date of such proposed
dissolution or liquidation. The Administrative Committee may at its sole discretion provide for an Grantee to have the right to exercise
his or her Option or Stock Purchase Right at any time until fifteen (15) days prior to the commencement of such proposed dissolution or
liquidation. In addition, the Administrative Committee may at its sole discretion provide that any repurchase option of the Company applicable
to any Award and/or any right of the Company to buy out outstanding Options under subsection 9(e) shall lapse upon dissolution or liquidation
of the Company, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated.

 

     

     

    

 

Page 13

 

		(c)	Merger or Asset Sale

 

In the event of a merger of the Company with or into another
corporation, or the sale of substantially all of the assets of the Company, each outstanding Award shall be assumed or an equivalent option
or share award substituted by the successor corporation or its holding company (meaning any entity which holds directly or indirectly
at least fifty point one percent of the voting equity of the successor corporation) or subsidiary (meaning any entity in which the successor
corporation holds directly or indirectly fifty point one percent or more of the voting equity). In the event that the successor corporation
or its holding company or subsidiary refuses to assume or substitute for the Award, the Grantee shall fully vest in and have the right
to exercise (where applicable) all of the Award, including such part of the Award as to which it would not otherwise be vested or exercisable
and the repurchase option of the Company applicable to any Award and/or any right of the Company to buy out outstanding Options under
subsection 9(e) shall lapse upon consummation of such merger or sale of assets. If an Award becomes fully vested and exercisable in lieu
of assumption or substitution in the event of a merger or sale of assets, the Administrative Committee shall accordingly notify the Grantee
in writing or electronically in which event the Award shall be fully exercisable for a period of fifteen (15) days from the date of such
notice, and the Award shall terminate upon the expiration of such fifteen (15) day period. For the purposes of this paragraph, the Award
shall be considered assumed if, following the merger or sale of assets, the outstanding Award confers the right to purchase or receive
proportionately the consideration (whether stock, cash, or other securities or property) received by holders of Ordinary Shares in the
merger or sale of assets; provided, however, that if such consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its holding company or subsidiary, the Administrative Committee may, with the consent of the successor
corporation, provide for the consideration to be received upon the exercise of the Award to be solely common stock of the successor corporation
or its holding company or subsidiary equal in fair market value to the per share consideration received by holders of Ordinary Shares
in the merger or sale of assets, such fair market value to be conclusively determined by the Administrative Committee.

 

		(d)	General Adjustment Rules

 

If any adjustment or substitution provided for in this Section
14 shall result in the creation of a fractional Ordinary Share under any Award, the Company shall, in lieu of issuing such fractional
Ordinary Share, pay to the Grantee a cash sum in the amount equal to the product of such fraction multiplied by the Fair Market Value
of an Ordinary Share on the date the fractional Ordinary Share otherwise would have been issued.

 

     

     

    

 

Page 14

 

		(e)	Determination by Administrative Committee

 

Adjustments under this Section 14 shall be made by the Administrative
Committee whose determinations with regard thereto shall be final, conclusive and binding upon all parties.

 

		15.	Time of Granting Awards

 

The date of grant of an Award shall, for all purposes, be
the date on which the Administrative Committee makes the determination granting such Award, or such other date as determined by the Administrative
Committee. Notice of the determination shall be given to each Service Provider to whom an Award is so granted within a reasonable time
after the date of such grant.

 

		16.	Amendment, Modification and Termination of the Plan

 

		(a)	Amendment, Modification and Termination

 

With the approval of the Board, at any time and from time to
time, the Committee may terminate, amend or modify the Plan; provided, however, that to the extent necessary and desirable to comply with
any applicable law, regulation, or stock exchange rule, unless the Company decides to follow home country practice pursuant to Rule 5615(a)(3)
of the Nasdaq listing rules applicable to foreign private issuers, the Company shall obtain shareholder approval of any Plan amendment
in such a manner and to such a degree as required.

 

		(b)	Awards Previously Granted

 

Except with respect to amendments made pursuant to Subsection
16(a), no termination, amendment, or modification of the Plan shall adversely affect in any material way any Awards previously granted
pursuant to the Plan without the prior written consent of the Service Provider.

 

		(c)	Effect of Amendment, Modification or Termination

 

No amendment, modification, suspension or termination of the
Plan shall impair the rights of any Grantee, unless mutually agreed otherwise between the Grantee and the Administrative Committee. Termination
of the Plan shall not affect the Administrative Committee’s ability to exercise the powers granted to it hereunder with respect
to Options, Restricted Shares or Restricted Share Units granted under the Plan prior to the date of such termination.

 

		17.	Conditions Upon Issuance of Shares

 

		(a)	Legal Compliance

 

Ordinary Shares shall not be issued pursuant to any Award unless
the vesting and/or exercise of such Award and the issuance and delivery of such Ordinary Shares shall comply with Applicable Laws and
shall be further subject to the approval of legal counsel for the Company with respect to such compliance.

 

     

     

    

 

Page 15

 

		(b)	Cash Payment

 

The payment of cash pursuant to the Plan shall be subject to
all Applicable Laws.

 

		(c)	Investment Representations

 

The Company may require any person to whom an Award is granted,
as a condition of exercising such Award or receiving Ordinary Shares pursuant to the Plan, to give written assurances, in the substance
and form satisfactory to the Company and its legal counsel, to the effect that such person is acquiring the Ordinary Shares subject to
the Award for his own account for investment and not with any present intention of selling or otherwise distributing the same, and to
such other effects as the Company deems necessary or appropriate in order to comply with applicable securities laws.

 

		(d)	Restrictions

 

The Administrative Committee may provide that Ordinary Shares
issuable upon the vesting and/or exercise of an Award shall, under certain conditions, be subject to restrictions whereby the Company
has a right of first refusal with respect to such Ordinary Shares, which restrictions may survive an Grantee’s term of employment,
engagement, appointment or service with the Company.

 

		18.	Inability to Obtain Regulatory Approval

 

The inability of the Company to obtain approval from any
regulatory body having jurisdiction over the Company with respect to issuance of Ordinary Shares pursuant to this Plan shall relieve the
Company of any liability in respect of the failure to issue such Ordinary Shares as to which such requisite approval shall not have been
obtained.

 

		19.	Information to Grantees and Purchasers

 

The Company shall provide to each Grantee and to each individual
who acquires Ordinary Shares pursuant to the Plan, not less frequently than annually during the period such Grantee or purchaser has one
or more Award outstanding, and, in the case of an individual who acquires Ordinary Shares pursuant to the Plan, during the period such
individual owns such Ordinary Shares, copies of annual financial statements. The Company shall not be required to provide such statements
to key employees whose duties in connection with the Company assure their access to equivalent information.

 

		20.	Withholding

 

The Company’s obligations to deliver Ordinary Shares
upon the exercise of an Option or Stock Purchase Right shall be subject to the Grantee’s satisfaction of all Applicable Laws related
to tax withholding as a result of such exercise.

 

		21.	Non-exclusivity of the Plan

 

The adoption of the Plan by the Board shall not be construed
as creating any limitations on the power or authority of the Board to adopt such other or additional incentive or other compensation arrangements
of whatever nature as the Board may deem necessary or desirable or preclude or limit the continuation of any other plan, practice or arrangement
for the payment of compensation or fringe benefits to employees generally, or to any class or group of employees, which the Company or
any Subsidiary now has lawfully put into effect, including, without limitation, any retirement, pension, savings and stock purchase plan,
insurance, death and disability benefits and executive short-term incentive plans.

assigned without the approval in writing of the Administrative Committee.
