Section 10.08Conflicts of Laws. The laws of the State of Delaware shall control the interpretation and performance of the terms of the Plan. The Plan is not intended to qualify under Section 401(a) of the Code or the Employee Retirement Income Security Act of 1974, as amended.

(10) days after the date such request is given, give notice thereof (the “Demand Notice”) to all Holders other than the Initiating Holders; and (y) as soon as practicable, and in any event within sixty (60) days
after the date such request is given by the Initiating Holders, file a Form S-1 registration statement under the Securities Act covering all Registrable Securities that the Initiating Holders requested to be
registered and any additional Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within twenty (20) days of the date the Demand Notice is
given, and in each case, subject to the limitations of Sections 2.01(c) and 2.3. 
 (b) Form
S-3 Demand. If, at any time after one hundred eighty (180) days after the consummation of the Company’s IPO, when it is eligible to use a Form S-3
registration statement, the Company receives a request from the Required Holders that the Company file a Form S-3 registration statement with respect to outstanding Registrable Securities of such Holders
having an anticipated aggregate offering price, net of Selling Expenses, of at least $2,500,000, then the Company shall (i) within ten (10) days after the date such request is given, give a Demand Notice to all Holders other than the
Initiating Holders; and (ii) as soon as practicable, and in any event within 45 days after the date such request is given by the Initiating Holders, file a Form S-3 registration statement under the
Securities Act covering all Registrable Securities requested to be included in such registration by any other Holders, as specified by notice given by each such Holder to the Company within twenty (20) days of the date the Demand Notice is
given, and in each case, subject to the limitations of Sections 2.01(c) and 2.03. 
 (c) Notwithstanding the foregoing
obligations, if the Company furnishes to Holders requesting a registration pursuant to this Section 2.01 a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the
Board of Managers it would be materially detrimental to the Company and its members for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain
effective, because it would be materially detrimental to the Company and its members for such registration statement to be filed and it is therefore necessary to defer the filing of such registration statement, then the Company 

 shall have the right to defer taking action with respect to such filing, and any time periods with respect
to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than one hundred twenty (120) days after the request of the Initiating Holders is given; provided, however, that the Company may not invoke this
right more than once in any 12 month period. 
 (d) The Company shall not be obligated to effect, or to take any action to effect, any
registration pursuant to Section 2.01(a) (i) during the period that is sixty (60) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is one hundred eighty (180)
days after the effective date of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; (ii) after the
Company has effected two registrations pursuant to Section 2.01(a); or (iii) if the Initiating Holders propose to dispose of shares of Registrable Securities that may be immediately registered on Form S-3 pursuant to a request made pursuant to Section 2.01(b). The Company shall not be obligated to effect, or to take any action to effect, any registration pursuant to
Section 2.01(b) (i) during the period that is thirty (30) days before the Company’s good faith estimate of the date of filing of, and ending on a date that is ninety (90) days after the effective date
of, a Company-initiated registration, provided that the Company is actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective; or (ii) if the Company has effected two
registrations pursuant to Section 2.1(b) within the twelve (12) month period immediately preceding the date of such request. A registration shall not be counted as “effected” for purposes of this
Section 2.01(d) until such time as the applicable registration statement has been declared effective by the SEC, unless the Initiating Holders withdraw their request for such registration, elect not to pay the registration
expenses therefor, and forfeit their right to one demand registration statement pursuant to Section 2.06, in which case such withdrawn registration statement shall be counted as “effected” for purposes of this
Section 2.01(d); provided, that if such withdrawal is during a period the Company has deferred taking action pursuant to Section 2.01(c), then the Initiating Holders may withdraw their
request for registration and such registration will not be counted as “effected” for purposes of this Section 2.01(d). 

2.02 Company Registration. If the Company proposes to register (including, for this purpose, a registration effected by the Company for
members other than the Holders) any of its securities under the Securities Act in connection with the public offering of such securities solely for cash (other than in an Excluded Registration), the Company shall, at such time, promptly give each
Holder notice of such registration. Upon the request of each Holder given within twenty (20) days after such notice is given by the Company, the Company shall, subject to the provisions of Section 2.03, cause to be
registered all of the Registrable Securities that each such Holder has requested to be included in such registration. The Company shall have the right to terminate or withdraw any registration initiated by it under this
Section 2.02 before the effective date of such registration, whether or not any Holder has elected to include Registrable Securities in such registration. The expenses (other than Selling Expenses) of such withdrawn
registration shall be borne by the Company in accordance with Section 2.06. 
 2.03 Underwriting
Requirements. 
 (a) If, pursuant to Section 2.01, 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 Section 2.01, and the Company shall include such information in the Demand
Notice. The underwriter(s) will be selected by the Company and shall be reasonably acceptable to a majority in interest of the Initiating Holders. In such event, the right of any Holder to include such Holder’s 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 (together with the Company as provided in Section 2.04(e)) enter into an underwriting 

 agreement in customary form with the underwriter(s) selected for such underwriting. Notwithstanding any
other provision of this Section 2.03, if the managing underwriter(s) advise(s) the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be underwritten, then the Initiating
Holders shall so advise all Holders of Registrable Securities that otherwise would be underwritten pursuant hereto, and the number of Registrable Securities that may be included in the underwriting shall be allocated among such Holders of
Registrable Securities, including the Initiating Holders, in proportion (as nearly as practicable) to the number of Registrable Securities owned by each Holder or in such other proportion as shall mutually be agreed to by all such selling Holders;
provided, however, that the number of Registrable Securities held by the Holders to be included in such underwriting shall not be reduced unless all other securities are first entirely excluded from the underwriting. To facilitate the
allocation of shares in accordance with the above provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. 

(b) In connection with any offering involving an underwriting of shares of the Company’s capital shares pursuant to
Section 2.02, the Company shall not be required to include any of the Holders’ Registrable Securities in such underwriting unless the Holders accept the terms of the underwriting as agreed upon between the Company and
its underwriters, and then only in such quantity as the underwriters in their sole discretion determine will not jeopardize the success of the offering by the Company. If the total number of securities, including Registrable Securities, requested by
members to be included in such offering exceeds the number of securities to be sold (other than by the Company) that the underwriters in their reasonable discretion determine is compatible with the success of the offering, then the Company shall be
required to include in the offering only that number of such securities, including Registrable Securities, which the underwriters and the Company in their sole discretion determine will not jeopardize the success of the offering. If the underwriters
determine that less than all of the Registrable Securities requested to be registered can be included in such offering, then the Registrable Securities that are included in such offering shall be allocated among the selling Holders in proportion (as
nearly as practicable to) the number of Registrable Securities owned by each selling Holder or in such other proportions as shall mutually be agreed to by all such selling Holders. To facilitate the allocation of shares in accordance with the above
provisions, the Company or the underwriters may round the number of shares allocated to any Holder to the nearest one hundred (100) shares. Notwithstanding the foregoing, in no event shall (i) the number of Registrable Securities included
in the offering be reduced unless all other securities (other than securities to be sold by the Company) are first entirely excluded from the offering, or (ii) the number of Registrable Securities included in the offering be reduced below 20%
of the total number of securities included in such offering, unless such offering is the IPO, in which case the selling Holders may be excluded further if the underwriters make the determination described above and no other member’s securities
are included in such offering For purposes of the provision in this Section 2.03(b) concerning apportionment, for any selling Holder that is a partnership, limited liability company, or corporation, the partners, members,
retired partners, retired members, members, and Affiliates of such Holder, or the estates and Immediate Family Members of any such partners, retired partners, members, and retired members and any trusts for the benefit of any of the foregoing
Persons, shall be deemed to be a single “selling Holder,” and any pro rata reduction with respect to such “selling Holder” shall be based upon the aggregate number of Registrable Securities owned by all Persons included in such
“selling Holder,” as defined in this sentence. 
 (c) For purposes of Section 2.01, a registration shall
not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Section 2.03(a), fewer than 50% of the total number of Registrable Securities that Holders have requested
to be included in such registration statement are actually included. 
 2.04 Obligations of the Company. Whenever required under this
Section 2 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 its commercially reasonable efforts to cause such registration statement to become effective and, upon the request of the Holders of a majority of the Registrable Securities registered thereunder, keep such registration statement
effective for a period of up to one hundred twenty (120) days or, if earlier, until the distribution contemplated in the registration statement has been completed; provided, however, that such one hundred twenty (120) day period
shall be extended for a period of time equal to the period the Holder refrains, at the request of an underwriter of Common Shares (or other securities) of the Company, from selling any securities included in such registration; 

(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 Securities Act in order to enable the disposition of all securities covered by such registration statement; 

(c) furnish to the selling Holders such numbers of copies of a prospectus, including a preliminary prospectus, as required by the Securities
Act, and such other documents as the Holders may reasonably request in order to facilitate their disposition of their Registrable Securities; 

(d) use its commercially reasonable efforts to register and qualify the securities covered by such registration statement under such other
securities or blue-sky laws of such jurisdictions as shall be reasonably requested by the selling Holders; provided that the Company shall not be required to qualify to do business or to file a general
consent to service of process in any such states or jurisdictions, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act; 

(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 underwriter(s) of such offering; 
 (f) use its commercially reasonable efforts to cause all such Registrable
Securities covered by such registration statement to be listed on a national securities exchange or trading system and each securities exchange and trading system (if any) on which similar securities issued by the Company are then listed; 

(g) provide a transfer agent and registrar for all Registrable Securities registered pursuant to this Agreement and provide a CUSIP number for
all such Registrable Securities, in each case not later than the effective date of such registration; 
 (h) promptly make available for
inspection by the selling Holders, any managing underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or accountant or other agent retained by any such underwriter or selected by the selling
Holders, all financial and other records, pertinent company documents, and properties of the Company, and cause the Company’s officers, managers, employees, and independent accountants to supply all information reasonably requested by any such
seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration statement and to conduct appropriate due diligence in connection therewith; 

(i) notify each selling Holder, promptly after the Company receives notice thereof, of the time when such registration statement has been
declared effective or a supplement to any prospectus forming a part of such registration statement has been filed; and 

 (j) after such registration statement becomes effective, notify each selling Holder of any
request by the SEC that the Company amend or supplement such registration statement or prospectus. In addition, the Company shall ensure that, at all times after any registration statement covering a public offering of securities of the Company
under the Securities Act shall have become effective, its insider trading policy shall provide that the Company’s managers may implement a trading program under Rule 10b5-1 of the Exchange Act. 

2.05 Furnish Information. It shall be a condition precedent to the obligations of the Company to take any action pursuant to this
Section 2 with respect to the Registrable Securities of any selling Holder that such Holder shall furnish to the Company such information regarding itself, the Registrable Securities held by it, and the intended method of
disposition of such securities as is reasonably required to effect the registration of such Holder’s Registrable Securities. 
 2.06
Expenses of Registration. All expenses (other than Selling Expenses) incurred in connection with registrations, filings, or qualifications pursuant to Section 2, including all registration, filing, and qualification
fees; printers’ and accounting fees; fees and disbursements of counsel for the Company; and the reasonable fees and disbursements of one counsel for the selling Holders (“Selling Holder Counsel”), shall be borne and paid
by the Company; provided, however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Section 2.01 if the registration request is subsequently withdrawn at
the request of the Holders of a majority of the Registrable Securities to be registered (in which case all selling Holders shall bear such expenses pro rata based upon the number of Registrable Securities that were to be included in the withdrawn
registration), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one registration pursuant to Sections 2.01(a) or 2.01(b), as the case may be; provided further that if, at the time of
such withdrawal, the Holders have learned of a material adverse change in the condition, business, or prospects of the Company from that known to the Holders at the time of their request and have withdrawn the request with reasonable promptness
after learning of such information, then the Holders shall not be required to pay any of such expenses and shall not forfeit their right to one registration pursuant to Sections 2.01(a) or 2.01(b). All Selling Expenses relating to
Registrable Securities registered pursuant to this Section 2 shall be borne and paid by the Holders pro rata on the basis of the number of Registrable Securities registered on their behalf. 

2.07 Delay of Registration. No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any
registration pursuant to this Agreement as the result of any controversy that might arise with respect to the interpretation or implementation of this Section 2. 

2.08 Indemnification. If any Registrable Securities are included in a registration statement under this
Section 2: 
 (a) To the extent permitted by law, the Company will indemnify and hold harmless each selling
Holder, and the partners, members, officers, directors, managers, members and stockholders of each such Holder; legal counsel and accountants for each such Holder; any underwriter (as defined in the Securities Act) for each such Holder; and each
Person, if any, who controls such Holder or underwriter within the meaning of the Securities Act or the Exchange Act, against any Damages, and the Company will pay to each such Holder, underwriter, controlling Person, or other aforementioned Person
any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages may result, as such expenses are incurred; provided, however, that the indemnity agreement
contained in this Section 2.08(a) shall not apply to amounts paid in settlement of any such claim or proceeding if such settlement is effected without the consent of the Company, which consent shall not be unreasonably
withheld, nor shall the Company be liable for any Damages to the extent that they arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of any such Holder,
underwriter, controlling Person, or other aforementioned Person expressly for use in connection with such registration. 

 (b) To the extent permitted by law, each selling Holder, severally and not jointly, will
indemnify and hold harmless the Company, and each of its managers, each of its officers who has signed the registration statement, each Person (if any), who controls the Company within the meaning of the Securities Act, legal counsel and accountants
for the Company, any underwriter (as defined in the Securities Act), any other Holder selling securities in such registration statement, and any controlling Person of any such underwriter or other Holder, against any Damages, in each case only to
the extent that such Damages arise out of or are based upon actions or omissions made in reliance upon and in conformity with written information furnished by or on behalf of such selling Holder expressly for use in connection with such
registration; and each such selling Holder will pay to the Company and each other aforementioned Person any legal or other expenses reasonably incurred thereby in connection with investigating or defending any claim or proceeding from which Damages
may result, as such expenses are incurred; provided, however, that the indemnity agreement contained in this Section 2.08(b) shall not apply to amounts paid in settlement of any such claim or proceeding if such
settlement is effected without the written consent of such Holder, which consent shall not be unreasonably withheld; and provided further that in no event shall the aggregate amounts payable by any Holder by way of indemnity or contribution
under Section 2.8(b) and 2.8(d) exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of fraud or willful misconduct by such Holder. 

(c) Promptly after receipt by an indemnified party under this Section 2.08 of notice of the commencement of any
action (including any governmental action) for which a party may be entitled to indemnification hereunder, such indemnified party will, if a claim in respect thereof is to be made against any indemnifying party under this
Section 2.08, give the indemnifying party notice of the commencement thereof. The indemnifying party shall have the right to participate in such action and, to the extent the indemnifying party so desires, participate
jointly with any other indemnifying party to which notice has been given, and to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party (together with all other indemnified
parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel
retained by the indemnifying party would be inappropriate due to actual or potential differing interests between such indemnified party and any other party represented by such counsel in such action. The indemnifying party shall not be entitled to
assume or maintain control of the defense of any claim and shall pay the fees and expenses of one counsel retained by the indemnified party if (i) the claim relates to or arises in connection with any criminal proceeding, action, indictment or
allegation or (ii) the claim seeks an injunction or equitable relief against the indemnified party or any of its affiliates. No indemnifying party in the defense of any such action shall, except with the consent of each indemnified party,
consent to entry of any judgment or enter into any settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party or a release from all liability in respect to such action. The
failure to give 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 2.08, to
the extent that such failure materially prejudices the indemnifying party’s ability to defend such action. The failure to give 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) To provide for just and equitable contribution to joint liability
under the Securities Act in any case in which either: (i) any party otherwise entitled to indemnification hereunder makes a claim for indemnification pursuant to this Section 2.08 but it is judicially determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and the expiration of time to appeal or the denial of the last right of appeal) that such indemnification may not be enforced in such case, notwithstanding the fact that
this Section 2.08 provides for indemnification in such case, or (ii) contribution 

 under the Securities Act may be required on the part of any party hereto for which indemnification is
provided under this Section 2.08, then, and in each such case, such parties will contribute to the aggregate losses, claims, damages, liabilities, or expenses to which they may be subject (after contribution from others) in
such proportion as is appropriate to reflect the relative fault of each of the indemnifying party and the indemnified party in connection with the statements, omissions, or other actions that resulted in such loss, claim, damage, liability, or
expense, as well as to reflect any other relevant equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by reference to, among other things, whether the untrue or allegedly untrue
statement of a material fact, or the omission or alleged omission of 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, however, that, in any such case (x) no Holder will be required to contribute any amount in excess of the public offering price of all such Registrable Securities
offered and sold by such Holder pursuant to such registration statement, and (y) no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) will be entitled to contribution from any Person
who was not guilty of such fraudulent misrepresentation; and provided further that in no event shall a Holder’s liability pursuant to this Section 2.08(d), when combined with the amounts paid or payable by such
Holder pursuant to Section 2.08(b), exceed the proceeds from the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder. 

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

(f) Unless otherwise superseded by an underwriting agreement entered into in connection with the underwritten public offering, the obligations
of the Company and Holders under this Section 2.08 shall survive the completion of any offering of Registrable Securities in a registration under this Section 2, and otherwise shall survive the
termination of this Agreement. 
 2.09 Reports Under Exchange Act. With a view to making available to the Holders the benefits of SEC
Rule 144 and any other rule or regulation of the SEC that may at any time permit a Holder to sell securities of the Company to the public without registration or pursuant to a registration on Form S-3, the
Company shall: 
 (a) make and keep available adequate current public information, as those terms are understood and defined in SEC Rule
144, at all times after the effective date of the registration statement filed by the Company for the IPO; 
 (b) use commercially
reasonable efforts to file with the SEC in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act (at any time after the Company has become subject to such reporting requirements); and

 (c) furnish to any Holder, so long as the Holder owns any Registrable Securities, forthwith upon request (i) to the extent accurate,
a written statement by the Company that it has complied with the reporting requirements of SEC Rule 144 (at any time after ninety (90) days after the effective date of the registration statement filed by the Company for the IPO), the Securities
Act, and the Exchange Act (at any time after the Company has become subject to such reporting requirements), or that it qualifies as a registrant whose securities may be resold pursuant to Form S-3 (at any
time after the Company so qualifies); and (ii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the SEC that permits the selling of any such securities without registration (at any time
after the Company has become subject to the reporting requirements under the Exchange Act) or pursuant to Form S-3 (at any time after the Company so qualifies to use such form). 

 2.10 Limitations on Subsequent Registration Rights. From and after the date of this
Agreement, the Company shall not, without the prior written consent of the Required Holders, enter into any agreement with any holder or prospective holder of any securities of the Company that would (i) provide to such holder or prospective
holder the right to include securities in any registration on other than a subordinate basis after all Holders have had the opportunity to include in the registration and offering all shares of Registrable Securities that they wish to so include or
(ii) allow such holder or prospective holder to include such securities in any registration unless, under the terms of such agreement, such holder or prospective holder may include such securities in any such registration only to the extent
that the inclusion of such securities will not reduce the number of the Registrable Securities of the Holders that are included. 
 2.11
“Market Stand-off” Agreement. Each Holder hereby agrees that it will not, without the prior written consent of the managing underwriter, during the period commencing on the date of the final
prospectus relating to the registration by the Company of its Common Shares or any other equity securities under the Securities Act on a registration statement on Form S-1 and ending on the date specified by
the Company and the managing underwriter (such period not to exceed one hundred eighty (180) days in the case of the IPO), (i) lend; offer; pledge; sell; contract to sell; sell any option or contract to purchase; purchase any option or contract
to sell; grant any option, right, or warrant to purchase; or otherwise transfer or dispose of, directly or indirectly, any Common Shares or any securities convertible into or exercisable or exchangeable (directly or indirectly) for Common Shares
held immediately before the effective date of the registration statement for such offering or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of such
securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Shares or other securities, in cash, or otherwise. The foregoing provisions of this Section 2.11
shall apply only to the IPO, and shall not apply to the sale of any shares to an underwriter pursuant to an underwriting agreement, to the establishment of a trading plan pursuant to Rule 10b5-1, provided that
such plan does not permit transfers during the restricted period, or to the transfer of any shares to an Affiliate of the Holder or to a trust for the direct or indirect benefit of the Holder or the Immediate Family Member of the Holder, provided
that the Affiliate or trustee of the trust (as applicable) agrees to be bound in writing by the restrictions set forth herein, and shall be applicable to the Holders only if all officers, directors and managers are subject to the same restrictions
and the Company uses commercially reasonable efforts to obtain a similar agreement from all members individually owning more than one percent (1%) of the Company’s then- outstanding Common Shares (after giving effect to conversion into Common
Shares of all outstanding Preferred Shares). The underwriters in connection with such registration are intended third-party beneficiaries of this Section 2.11 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 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 shares subject to such agreements, unless otherwise approved by the Required Holders. 

2.12 Termination of Registration Rights. The right of any Holder to request registration or inclusion of Registrable Securities in any
registration pursuant to Sections 2.01 or 2.02 shall terminate upon the earliest to occur of: 
 (a) the closing of a Deemed
Liquidation Event (as defined in the Operating Agreement); 

 (b) such time after consummation of the IPO as SEC Rule 144 or another similar exemption
under the Securities Act is available for the sale of all of such Holder’s shares without limitation during a three-month period without registration; and 

(c) the fifth anniversary of the IPO.

thereto that may be required in accordance with GAAP); 
 (c) as soon as practicable, but in any event within forty-five (45) days

 If, for any period, the Company has any subsidiary whose accounts are consolidated with
those of the Company, then in respect of such period the financial statements delivered pursuant to the foregoing sections shall be the consolidated and consolidating financial statements of the Company and all such consolidated subsidiaries. 

Notwithstanding anything else in this Section 3.01 to the contrary, the Company may cease providing the information
set forth in this Section 3.01 during the period starting with the date sixty (60) days before the Company’s good-faith estimate of the date of filing of a registration statement if it reasonably concludes it must
do so to comply with the SEC rules applicable to such registration statement and related offering; provided that the Company’s covenants under this Section 3.01 shall be reinstated at such time as the Company is
no longer actively employing its commercially reasonable efforts to cause such registration statement to become effective. 
 3.02
Inspection. The Company shall permit each Investor, provided that the Board of Managers has not reasonably determined that such Investor is a Competitor of the Company, at such Investor’s expense, to visit and inspect the
Company’s properties; examine its books of account and records; and discuss the Company’s affairs, finances, and accounts with its officers, during normal business hours of the Company as may be reasonably requested by the Investor;
provided, however, that the Company shall not be obligated pursuant to this Section 3.02 to provide access to any information that it reasonably and in good faith considers to be a trade secret or confidential
information (unless covered by an enforceable confidentiality agreement, in form acceptable to the Company) or the disclosure of which would adversely affect the attorney-client privilege between the Company and its counsel. 

3.03 Observer Rights. The Company shall invite a representative of Atlas, for so long as such Investor owns not less than 500,000
Preferred Shares (or an equivalent amount of Common Shares issued upon conversion thereof), which number is subject to appropriate adjustment for any share splits, share dividends, combinations, recapitalizations and the like, to attend all meetings
of the Board of Managers in a nonvoting observer capacity and, in this respect, shall give such representative copies of all notices, minutes, consents, and other materials that it provides to its managers at the same time and in the same manner as
provided to such managers; provided, however, that such representative shall agree to hold in confidence and trust and to act in a fiduciary manner with respect to all information so provided; and provided further, that
the Company reserves the right to withhold any information and to exclude such representative from any meeting or portion thereof if access to such information or attendance at such meeting could adversely affect the attorney-client privilege
between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest, or if such Investor or its representative is a competitor of the Company. 

3.04 Termination of Information and Observer Rights. The covenants set forth in Section 3.01,
Section 3.02 and Section 3.03 shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, (ii) when the Company first becomes subject to the
periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act, or (iii) upon the closing of a Deemed Liquidation Event, whichever event occurs first. 

3.05 Confidentiality. Each Investor severally agrees that such Investor will keep confidential and will not disclose, divulge, or use
for any purpose (other than to monitor its investment in the Company or to enforce its rights under this Agreement or any other agreement between the Company and the Investors) any confidential information obtained from the Company pursuant to the
terms of this Agreement (including notice of the Company’s intention to file a registration statement), unless such confidential information (a) is known or becomes known to the public in general (other than as a result of a breach of this
Section 3.05 by such Investor), (b) is or has been independently developed or conceived by such Investor without use of the Company’s confidential information, or (c) is or has been made known or disclosed to such
Investor by a third party without a breach of any obligation of confidentiality such third 

 party may have to the Company; provided, however, that an Investor may disclose confidential
information (i) to its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company or to enforce its rights under this Agreement or any
other agreement between the Company and the Investors; (ii) to any prospective purchaser of any Registrable Securities from such Investor, if such prospective purchaser is subject to a confidentiality agreement with such Investor or is
otherwise bound to keep such information confidential by obligations at least as restrictive as the provisions of this Section 3.05 and provided that such prospective purchaser is not a Competitor of the Company;
(iii) to any regulator, existing or prospective Affiliate, partner, member, stockholder, or wholly owned subsidiary of such Investor in the ordinary course of business, provided that, to the extent permitted by applicable law, such
Investor informs such Person that such information is confidential and directs such Person to maintain the confidentiality of such information; or (iv) as may otherwise be required by law, regulation, rule, court order or subpoena,
provided, to the extent permitted by applicable law, that such Investor promptly notifies the Company of such disclosure and takes reasonable steps to minimize the extent of any such required disclosure. 

ARTICLE IV. Rights to Future Share Issuances 

4.01 Right of First Offer. Subject to the terms and conditions of this Section 4.1 and applicable securities
laws, if the Company proposes to offer, issue or sell any New Securities, the Company shall first offer such New Securities to each Investor. An Investor shall be entitled to apportion the right of first offer hereby granted to it in such
proportions as it deems appropriate, among itself and its Affiliates; provided that each such Affiliate agrees to become a party to the Operating Agreement. 

(a) The Company shall give written notice (the “Offer Notice”) to each Investor, stating (i) its bona fide
intention to offer such New Securities, (ii) the number of such New Securities to be offered, and (iii) the price and terms, if any, upon which it proposes to offer such New Securities. 

(b) By notification to the Company within twenty (20) days after the Offer Notice is given, each Investor may elect to purchase or
otherwise acquire, at the price and on the terms specified in the Offer Notice, up to that portion of such New Securities which equals the proportion that the total number of Common Shares then held by such Investor (including all Common Shares then
issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Shares and any other Derivative Securities then held by such Investor) bears to the total number of Common Shares and Incentive Shares of the Company
then outstanding (assuming full conversion and/or exercise, as applicable, of all Preferred Shares and any other Derivative Securities then outstanding) (such proportion, the “Relative Percentage”). At the expiration
of such twenty (20) day period, the Company shall promptly notify in writing each Investor that elects to purchase or acquire all the shares available to it (each, a “Fully Exercising Investor”) of any other
Investor’s failure to do likewise. During the ten (10) day period commencing after the Company has given such notice, each Fully Exercising Investor may, by giving notice to the Company, elect to purchase or acquire, in addition to the
number of shares specified above, up to that portion of the New Securities for which Investors were entitled to subscribe but that were not subscribed for by the Investors which is equal to the proportion that the total number of Common Shares
issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of Preferred Shares and any other Derivative Securities then held, by such Fully Exercising Investor bears to the total number of Common Shares
issued and held, or issuable (directly or indirectly) upon conversion and/or exercise, as applicable, of the Preferred Shares and any other Derivative Securities then held, by all Fully Exercising Investors who wish to purchase such unsubscribed New
Securities. The closing of any sale pursuant to this Section 4.1(b) shall occur within the later of one hundred and twenty (120) days of the date that the Offer Notice is given and the date of the initial sale of New
Securities pursuant to Section 4.01(c). 

 (c) If all New Securities referred to in the Offer Notice are not elected to be purchased
or acquired as provided in Section 4.01(b), the Company may, during the ninety (90) day period following the expiration of the periods provided in Section 4.01(b), offer and sell the remaining
unsubscribed portion of such New Securities to any Person or Persons at a price not less than, and upon terms no more favorable to the offeree than, those specified in the Offer Notice. If the Company does not enter into an agreement for the sale of
the New Securities within such period, or if such agreement is not consummated within thirty (30) days of the execution thereof, the right provided hereunder shall be deemed to be revived and such New Securities shall not be offered unless
first reoffered to the Investors in accordance with this Section 4.01. 
 (d) The right of first offer in this
Section 4.01 shall not be applicable to (i) Exempted Securities (as defined in the Operating Agreement); (ii) Common Shares issued in the IPO; (iii) and the issuance of Series B Preferred Shares pursuant to the
Purchase Agreement. 
 4.02 Termination. The right of first offer set forth in Section 4.01 shall terminate
and be of no further force or effect (i) immediately before the consummation of the IPO or (ii) upon the closing of a Deemed Liquidation Event, as such term is defined in the Operating Agreement, whichever event occurs first. 

ARTICLE V. Additional Covenants. 

5.01 Insurance. The Company shall continue to maintain, from financially sound and reputable insurers, Managers and Officers liability
insurance in an amount (which shall be no less than $3,000,000) and on terms and conditions satisfactory to the Board of Managers, including at least two of the Preferred Managers (as defined in the Operating Agreement), and will use commercially
reasonable efforts to cause such insurance policies to be maintained until such time as the Board of Managers, including at least two of the Preferred Managers, determine that such insurance should be discontinued. The policy will not be cancelable
by the Company without prior approval by the Board of Managers, including at least two of the Preferred Managers. 
 5.02 Employee
Incentive Shares. Unless otherwise approved by the Board of Managers, including at least two of the Preferred Managers, all future employees and consultants of the Company and its subsidiaries who purchase or receive awards of incentive shares
after the date hereof shall be required to execute award agreements providing for (i) vesting of incentive shares over a four year period, with the first 25% of such incentive shares vesting following twelve (12) months of continued
employment or service, and the remaining incentive shares vesting in equal monthly installments over the following thirty-six (36) months (which may, at the discretion of the Board of Managers, include
double- trigger acceleration) or such other standard vesting schedule as has been approved by the Board of Managers, including at least two of the Preferred Managers, and (ii) a market stand-off provision
substantially similar to that in Section 2.15 of the Operating Agreement. 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 award agreement with any existing employee or service provider if such amendment would cause it to be inconsistent with this Section 5.02. 

5.03 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 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 Operating Agreement, or elsewhere, as the case may be. 

 5.04 Right to Conduct Activities. The Company hereby agrees and acknowledges that
certain of the Investors, including RA Capital, AI Day1 LLC, Viking, Franklin Strategic Series – Franklin Biotechnology Discovery Fund, Boxer Capital, LLC, and MVA Investors, LLC and their Affiliates, and representatives are professional
investment organizations, and as such review 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). The Company hereby agrees that, to the extent permitted under applicable law, such Investor (or their Affiliates) shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by
such Investors (or their Affiliates) in any entity competitive with the Company, or (ii) actions taken by any partner, manager, officer, employee or other representative of such Investor (or their 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. 
 5.05 Harassment Policy. The Company shall, and shall cause any of its
subsidiaries with employees to, within sixty (60) days following the Initial Closing (as defined in the Purchase Agreement), adopt and thereafter 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 policies shall be reviewed and approved by the Board of Managers. 

5.06 Publicity. The Company shall not use the name of any Investor or any of their respective Affiliates in any trade publication,
marketing materials or otherwise to the general public, in each case without the prior written consent of such Investor, which consent may be withheld by such Investor in its sole discretion; provided that (a) the parties anticipate that there
will be a mutually-agreed press release announcing the closing of the transaction contemplated in the Purchase Agreement and (b) following the public announcement contemplated in clause (a), the Company may confirm that such Investor is an
investor in the Company (but not the amount or terms thereof) in a form of disclosure that has been previously approved by such Investor. Notwithstanding the foregoing, the Company may disclose the terms and/or amount of the investment by an
Investor, without the prior approval of such Investor, (x) to a bona fide potential investor in or acquirer of the Company in connection with such potential investor’s or acquirer’s due diligence process or (y) as required by
law, rule, regulation or listing standard to do so; in which case the Company (i) shall promptly notify such Investor of such requirement and will cooperate with such Investor, to the extent practicable to limit the information disclosed to
only such information that the Company, as advised by counsel, is required by law to be disclosed and (ii) will, to the extent practicable and at the request and expense of such Investor, as applicable, seek to obtain a protective order over,
or confidential treatment of, such information. 
 5.07 FCPA. The Company represents that it shall not (and shall not permit any of
its subsidiaries or affiliates or any of its or their respective directors, officers, managers, employees, 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 represents that it shall (and shall cause each of its subsidiaries and affiliates to) cease all of its or their respective activities, as well as
remediate any actions taken by the Company, its subsidiaries or affiliates, or any of their respective directors, officers, managers, employees, independent contractors, representatives or agents in violation of the FCPA, the U.K. Bribery Act, or
any other applicable anti-bribery or anti-corruption law. The Company further represents that it shall 

 (and shall cause each of its subsidiaries and affiliates to) maintain systems of internal controls
(including, but not limited to, accounting systems, purchasing systems and billing systems) to ensure compliance with the FCPA, the U.K. Bribery Act, or any other applicable anti-bribery or anti-corruption law. Upon request, the Company agrees to
provide responsive information and/or certifications concerning its compliance with applicable anti-corruption laws. The Company shall promptly notify each Investor if the Company becomes aware of any enforcement action. The Company shall, and shall
cause any direct or indirect subsidiary or entity controlled by it, whether now in existence or formed in the future, to comply with the FCPA. The Company shall use its best efforts to cause any direct or indirect subsidiary, whether now in
existence or formed in the future, to comply in all material respects with all applicable laws. 
 5.08 Termination of Covenants. The
covenants set forth in this Section 5, except for Section 5.03, shall terminate and be of no further force or effect (i) immediately before the consummation of the IPO, (ii) when the
Company first becomes subject to the periodic reporting requirements of Section 12(g) or 15(d) of the Exchange Act, or (iii) upon a Deemed Liquidation Event, whichever event occurs first. In addition, the covenant set forth in
Section 5.04 shall terminate and be of no further force or effect upon the conversion of the Company from a limited liability company to a C corporation, whether by way of a statutory conversion, merger or otherwise. 

ARTICLE VI. Miscellaneous. 

6.01 Successors and Assigns. The rights under this Agreement may be assigned (but only with all related obligations) by a Holder to a
transferee of Registrable Securities that (i) is an Affiliate of a Holder; (ii) is a Holder’s Immediate Family Member or trust for the benefit of an individual Holder or one or more of such Holder’s Immediate Family Members; or
(iii) after such transfer, holds at least 500,000 shares of Registrable Securities (subject to appropriate adjustment for share splits, share dividends, combinations, and other recapitalizations); provided, however, that (x) the Company
is, within a reasonable time after such transfer, furnished with written notice of the name and address of such transferee and the Registrable Securities with respect to which such rights are being transferred; and (y) such transferee agrees in
a written instrument delivered to the Company to be bound by and subject to the terms and conditions of this Agreement, including the provisions of Section 2.11. For the purposes of determining the number of shares of
Registrable Securities held by a transferee, the holdings of a transferee (1) that is an Affiliate or stockholder of a Holder; (2) who is a Holder’s Immediate Family Member; or (3) that is a trust for the benefit of an individual
Holder or such Holder’s Immediate Family Member shall be aggregated together and with those of the transferring Holder; provided further that all transferees who would not qualify individually for assignment of rights shall, as a condition to
the applicable transfer, establish a single attorney-in-fact for the purpose of exercising any rights, receiving notices, or taking any action under this Agreement. The
terms and conditions of this Agreement inure to the benefit of and are binding upon the respective successors and permitted assignees of the parties. Nothing in this Agreement, express or implied, is intended to confer upon any party other than the
parties hereto or their respective successors and permitted assignees any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided herein. 

6.02 Governing Law. This Agreement shall be governed by the internal law of the State of Delaware, without regard to conflict of law
principles that would result in the application of any law other than the law of the State of Delaware. 
 6.03 Counterparts. This
Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or
any electronic signature complying with the U.S. federal ESIGN Act of 2000, the Uniform Electronic Transactions Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed
to have been duly and validly delivered and be valid and effective for all purposes. 

 6.04 Titles and Subtitles. The titles and subtitles used in this Agreement are for
convenience only and are not to be considered in construing or interpreting this Agreement. 
 6.05 Notices. 

(a) All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given
upon the earlier of actual receipt or (i) personal delivery to the party to be notified; (ii) when sent, if sent by electronic mail during the recipient’s normal business hours, and if not sent during normal business hours, then on
the recipient’s next business day; (iii) five days after having been sent by registered or certified mail, return receipt requested, postage prepaid; or (iv) one business day after the business day of deposit with a nationally
recognized overnight courier, freight prepaid, specifying next-day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their addresses (and with such
copies, which shall not constitute notice) as set forth on Schedule A hereto, or to the principal office of the Company and to the attention of the Chief Executive Officer, in the case of the Company, or to such email address, facsimile
number, or address as subsequently modified by written notice given in accordance with this Section 6.05. If notice is given to the Company, it shall be sent to 395 Oyster Point Blvd, Suite 217, South San Francisco, CA
9408, Attention: Jeremy Bender, CEO; and a copy (which shall not constitute notice) shall also be sent to Fenwick & West LLP, 555 California Street, San Francisco, CA 94104, Attention: Effie Toshav. 

(b) Consent to Electronic Notice. Each Investor consents to the delivery of any notice to such Investor pursuant to the Delaware
Limited Liability Company Act (the “Act”), as amended or superseded from time to time, by electronic transmission pursuant to Section 18-113 of the Act (or any successor thereto)
at the electronic mail address or the facsimile number set forth below such Investor’s name on the Schedules hereto, as updated from time to time by notice to the Company, or as on the books of the Company. Each Investor agrees to promptly
notify the Company of any change in such Investor’s electronic mail address, and that failure to do so shall not affect the foregoing. 

6.06 Amendments and Waivers. 

(a) Any term of this Agreement may be amended, modified or terminated and the observance of any term of this Agreement may be waived (either
generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the Company and the Required Holders; provided that any provision hereof may be waived by any waiving party on such
party’s own behalf, without the consent of any other party; provided further that Section 5.07 hereof may only be amended, modified or terminated and the observance of Section 5.07 as
it relates to any Investor, may be waived only with the prior consent of such Investor. Notwithstanding the foregoing, this Agreement may not be amended, modified or terminated and the observance of any term hereof may not be waived with respect to
any Investor without the written consent of such Investor, unless such amendment, modification, termination, or waiver applies to all Investors in the same fashion. Notwithstanding the foregoing, Schedule A hereto may be amended by the
Company from time to time to add transferees of any Registrable Securities in compliance with the terms of this Agreement without the consent of the other parties. The Company shall give prompt notice of any amendment, modification or termination
hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, modification, termination, or waiver. Any amendment, modification, termination, or waiver effected in accordance with this Section 6.06
shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or
construed as a further or continuing waiver of any such term, condition, or provision 

 (b) In the event of any waiver of the provisions of Section 4 with respect to a
particular issuance of New Securities that an Investor does not consent to in writing (each, a “Non- Participating Investor”), if any of the Investors participate in such waiver and also purchase New Securities in such
particular offering (the “Participating Investors”) then each Non-Participating Investor shall have the right to purchase its Relative Percentage of the New Securities, calculated in
accordance with the provisions of Section 4, absent such waiver and on the same terms and conditions as the Participating Investor. The Company shall provide written notice to each Non-Participating
Investor of such right, if applicable in connection with a particular issuance of New Securities, no later than the date of the initial closing of such issuance (the “Participation Rights Notice”). The Participation Rights
Notice shall state the number of New Securities issued, or to be issued, to the Participating Investors (as well as any other investors) and shall include any term sheet and all definitive documents entered into in connection with such issuance of
New Securities. Each Non-Participating Investor may exercise its rights pursuant to the provisions of this Section 6.06(b) by providing written notice to the Company of its intent to do so within twenty
(20) days of receipt of the particular Participation Rights Notice, and will forfeit such rights with respect to such Participation Rights Notice in the event that it does not do so. 

6.07 Severability. In case any one or more of the provisions contained in this Agreement is for any reason held to be invalid,
illegal or unenforceable in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid, illegal, or unenforceable provision shall be reformed and construed so that it will
be valid, legal, and enforceable to the maximum extent permitted by law. 
 6.08 Aggregation of Shares. All shares of
Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and such Affiliates may apportion such rights as among themselves in any manner
they deem appropriate. 
 6.09 Entire Agreement. This Agreement (including any Schedules and Exhibits hereto) constitutes the
full and entire understanding and agreement among the parties with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled. 

6.10 Dispute Resolution. The parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of
Delaware and to the jurisdiction of the United States District Court for the District of Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or
other proceeding arising out of or based upon this Agreement except in the state courts of Delaware or the United States District Court for the District of Delaware, and (c) hereby waive, and agree 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 may not be enforced in or by such court. 

WAIVER OF JURY TRIAL: EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS
AGREEMENT, THE OTHER TRANSACTION DOCUMENTS, THE SECURITIES OR THE SUBJECT MATTER HEREOF OR THEREOF. THE SCOPE OF THIS WAIVER IS INTENDED TO BE ALL-ENCOMPASSING OF ANY AND ALL DISPUTES THAT MAY BE FILED IN ANY

 COURT AND THAT RELATE TO THE SUBJECT MATTER OF THIS TRANSACTION, INCLUDING, WITHOUT LIMITATION, CONTRACT
CLAIMS, TORT CLAIMS (INCLUDING NEGLIGENCE), BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. THIS SECTION HAS BEEN FULLY DISCUSSED BY EACH OF THE PARTIES HERETO AND THESE PROVISIONS WILL NOT BE SUBJECT TO ANY EXCEPTIONS. EACH
PARTY HERETO HEREBY FURTHER WARRANTS AND REPRESENTS THAT SUCH PARTY HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT SUCH PARTY KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. 

To the extent permitted by applicable law, the prevailing party shall be entitled to reasonable attorney’s fees, costs, and necessary disbursements in
addition to any other relief to which such party may be entitled. 
 6.11 Delays or Omissions. No delay or omission to exercise any
right, power, or remedy accruing to any party under this Agreement, upon any breach or default of any other party under this Agreement, shall impair any such right, power, or remedy of such non-breaching or non-defaulting party, nor shall it be construed to be a waiver of or acquiescence to any such breach or default, or to any similar breach or default thereafter occurring, nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or thereafter occurring. All remedies, whether under this Agreement or by law or otherwise afforded to any party, shall be cumulative and not alternative.
