2.4    Charitable Purposes. 

(a)    The Company shall at all times be operated and managed in a manner that furthers ISMMS’s charitable mission.
ISMMS’s charitable mission shall take precedence over the duty of the Company or the Board of Managers of the Company to operate for the financial benefit of the Members of the Company. In the event of a conflict between the ISMMS’s

to the profitability of the Company. 
 (b)    The Company shall be operated and managed in a manner that will not, in
the reasonable opinion of ISMMS, on advice of its legal and/or tax counsel, cause the Company to (i) act other than in furtherance of the tax-exempt purposes of ISMMS, or (ii) act in any manner that
would adversely affect ISMMS’s tax exempt status under Section 501(c)(3) of the Code. 

(c)    Notwithstanding any power vested in the Board of Managers by applicable law or by the provisions of this Agreement,
the Board of Managers shall not take any action that would conflict with the provisions of this Section 2.4.

tax-exempt status of ISMMS or any of its Affiliates (a

“Jeopardy Event”), ISMMS may elect to renegotiate this Agreement by giving written notice thereof to Renalytix. If such notice is provided, ISMMS and Renalytix shall negotiate in good
faith during the sixty (60) day period after the date the written notice is given, in an effort to develop a revised agreement or modify the activities or operations of the Company, that, to the extent reasonably practicable, when implemented
will adequately resolve and avoid the Jeopardy Event, in the reasonable discretion of ISMMS, while at the same time keeping ISMMS and Renalytix in a position that is substantially similar to the position in which each was in prior to such
renegotiation. 
 (e)    In the event ISMMS and Renalytix are unable in good faith to develop a revised agreement, or to
otherwise correct the offending conduct, upon expiration of the sixty (60) day period described above, unless such period is extended by the mutual agreement of the parties, ISMMS shall have the option to redeem its interests in the Company,
terminate the ISMMS IP License Agreement and ISMMS TM License Agreement, assign the Approved Manufacturer Agreements to ISMMS or an Affiliate of ISMMS, and withdraw.

Class A Units at fair market value as determined by the Board of Managers in its reasonable discretion and having such attributes as the Board of Managers shall determine, in each case, with any approval of the Board as shall be required by
this Agreement. The Board of Managers is authorized to accept Capital Contributions from Members from time to time in its discretion in order to capitalize the Company with Capital Contributions that are in the judgment of the Board of Managers
sufficient to enable the Company to undertake and operate the Business. Each such Member shall be deemed admitted to the Company when the Board of Managers has accepted its Capital Contribution. 

3.2    Issuance of Profits Interests. 

(a)    The Company hereby issues 250 Class A Profits Interests Units to Renalytix in respect of the services to be
rendered under the ASA. The Company hereby issues 

  
 12 













 
750 Class A Profits Interests Units to ISMMS as partial consideration for the rights granted by ISMMS to the Company under the ISMMS IP License Agreement. For purposes of the determination
of the Value Increase for all Class A Profits Interest Units issued pursuant to this Section 3.3(a), the value of the Company as of the date hereof shall be deemed to be $0.00 (Zero Dollars). 

(b)    Of the 250 Class A Profits Interest issued to Renalytix pursuant to Section 3.2(a), sixty-three
Class A Profits Interests shall not be subject to forfeiture. The remaining one hundred eighty-seven Class A Profits Interest Units issued to Renalytix pursuant to Section 3.2(a) (the “Unvested Units”) shall be subject to
forfeiture as follows: if prior to December 31, 2020, the Company shall terminate the ASA in accordance with the terms of the ASA as a result of Renalytix’s material breach of the ASA (after giving the notice and affording the opportunity
to cure that is contemplated by the ASA) or pursuant to Section 12.1(b)(iii) of the ASA, then Renalytix shall retain a percentage of such Unvested Units determined by dividing the number of full calendar months commencing with May 1, 2020,
and ending December 31, 2020, for which the ASA was in effect prior to such termination by eight, and the balance of the Unvested Units shall be deemed to have been forfeited as of the date of such termination. If as of December 31, 2020,
the ASA has not been terminated by the Company in accordance with the terms of the ASA as a result of Renalytix’s material breach of the ASA (after giving the notice and affording the opportunity to cure that is contemplated by the ASA) or
pursuant to Section 12.1(b)(iii) of the ASA, then thereafter none of such one hundred eighty-seven Class A Profits Interest Units issued to Renalytix pursuant to Section 3.2(a) shall be subject to forfeiture. Even if any Class A
Profits Interest Units issued to Renalytix pursuant to Section 3.2(a) shall be forfeited, Renalytix shall not as a result of such forfeiture be required to return any distributions of Available Cash that have theretofore been made by the
Company to Renalytix in respect of such forfeited Class A Profits Interest Units. 
 (c)    If there occurs a
Change of Control at any time while the Unvested Units are subject to forfeiture as prescribed in Section 3.2(b) hereof, such Unvested Units shall become fully vested and no longer subject to forfeiture upon the entry into the definitive
agreement governing such Change of Control. No Class A Profits Interests issued to Renalytix pursuant to Section 3.2(a) that have not been forfeited as of the date of a Change of Control shall be subject to forfeiture from and after the
date of a Change of Control. 
 (d)    The 750 Class A Profits Units Interests issued to ISMMS pursuant to
Section 3.2(a) shall not be subject to forfeiture. 
 (e)    The Class A Profits Interest Units are intended
to be treated as “profits interests” in the Company as defined in Revenue Procedure 93-27. A Class A Unit Holder may make an election pursuant to Section 83(b) of the Code upon the grant of
any Class A Profits Interest Units. In the event of a change of law in respect of the tax treatment of the grant of a “profits interest” to a service provider, the Board of Managers and each Member shall take all actions as may
reasonably be required to maintain, to the extent possible, the tax treatment of grants of “profits interests” in return for services provided to, or for the benefit, of the Company as contemplated by Revenue Procedures 93-27 and 2001-43. For the avoidance of doubt, such actions shall include necessary or advisable amendments of this Agreement. Notwithstanding anything to the contrary
contained herein, the Company and the Members agree to treat each 

  
 13 













 
holder of Class A Profits Interest Units, even if subject to forfeiture, as the owner of the Class A Profits Interest Units issued to such holder from the date such Class A Profits
Interest Units are issued to such holder, within the meaning of Section 4.01 of Rev. Proc. 2001-43, 2001-2 C.B. 191. Each holder of Class A Profits Interest
Units will take into account its distributive share of Company income, gain, loss, deduction and credit associated with the Class A Units issued to each such holder from the date such Class A Units are issued in computing each such
holder’s income tax liability for the entire period during which such holder holds such Class A Profits Interest Units, as provided for in Article III of this Agreement. Neither the Company nor any Members will deduct the fair market value
of the Class A Profits Interest Units as wages, compensation or otherwise, at the time Class A Profits Interest Units are issued or at any other time. By executing this Agreement, each holder of Class A Profits Interest Units
acknowledges that it is responsible for determining the income tax consequences to it of acquiring or holding its Class A Profits Interest Units. 

3.3    Capital Accounts. 

(a)    The Company established and shall maintain a capital account (“Capital Account”) for each Member in
accordance with Section 704(b) of the Code and Treasury Regulations Section 1.704-1(b)(2)(iv). There shall be credited to the Capital Account of each Member the Capital Contribution made by such
Member, which upon the formation of the Company the Members acknowledge and agree shall be zero for each Member. Except as otherwise provided in this Agreement, and in any event pursuant to the requirements of Treasury Regulations Section 1.704-1(b)(2)(iv), the Capital Account balance of each Member shall be credited (increased) by (i) the amount of money contributed by such Member to the capital of the Company as a Capital
Contribution or as an Additional Capital Contribution, (ii) the fair market value of property contributed by such Member to the capital of the Company net of liabilities secured by such property that the Company assumes or takes subject to, and
(iii) such Member’s allocable share of Company income and gain (or items thereof), including income and gain exempt from taxation; and the Capital Account balance of each Member has been and shall be debited (decreased) by (x) the
amount of cash distributed to such Member, (y) the fair market value of property distributed to such Member (net of liabilities secured by such property that the Member assumes or takes subject to), and (z) such Member’s share of
Company losses, depreciation and other deductions, including such Member’s share of expenditures of the Company described in Section 705(a)(2)(B) of the Code. Notwithstanding the foregoing, a Member’s Capital Account shall not be
adjusted to reflect gain or loss attributable to the disposition of property contributed by such Member to the extent such Member’s Capital Account reflected such inherent gain or loss in the property on the date of its contribution to the
Company. 
 (b)    Upon the Transfer of a Company Interest, the transferee shall succeed to the Capital Account of the
transferor to the extent it relates to the transferred interest, except to the extent provided in Treasury Regulations Section 1.704-1(b)(2)(iv)(m). 

(c)    In the absolute discretion of the Board of Managers, the property of the Company shall be revalued in accordance
with Treasury Regulations Section 1.704-1(b)(2)(iv)(f) and the Capital Accounts of all Members shall be adjusted upon occurrence of any of the events set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(f)(5) to reflect the manner in which 

  
 14 













 
the unrealized income, gain, loss and deduction inherent in all the Company’s property (that has not previously been reflected in the Capital Accounts) would be allocated among the Members
if there was a taxable disposition of all such property on the date of the occurrence of any such event. 

3.4    Issuance of Additional Units. 

(a)    If after the initial capitalization of the Company the Board of Managers determines in its absolute discretion that
it is in the best interest of the Company to raise additional capital, then, the Board of Managers may in its absolute discretion, and is hereby granted all requisite authority to, raise additional capital for the Company by issuing additional Units
pursuant to the terms of this Section 3.4. 
 (b)    If the Board of Managers determines to issue additional Units
(the “Additional Units”) in accordance with the provisions of Section 3.4(a), then prior to offering the Additional Units to any Person (a “Third Party”) other than the Members and their Affiliates, the Board of Managers
shall offer such Additional Units to the Members in writing. The Members shall have the right for ten (10) days following the giving of notice of such offer in writing to purchase all or any portion of such Additional Units for a purchase price
equal to the Additional Units Purchase Price. Each Member that elects to purchase Additional Units shall be entitled to purchase, for a pro rata portion of the Additional Unit Purchase Price (such pro rata portion for each electing Member, its
“Additional Capital Contribution”), a portion of the Additional Units equal to the Additional Units to be issued multiplied by a fraction, the numerator of which shall be the Member Percentage Interest of such Member, and the denominator
of which shall be the sum of the Percentage Interests of all the Members electing to purchase Additional Units. To the extent a Member does not elect to purchase all the Additional Units to which such Member is entitled, then other Members may
purchase such excess Additional Units in the same proportion that each such other Member’s Percentage Interest bears to the aggregate Member Percentage Interests of all the other Members that elect to purchase such excess Additional Units. 

(c)    Any Additional Units not purchased by the Members under subsection (b) above may, if the Board of Managers so
elects in its absolute discretion, be offered and sold to Third Parties for the Additional Unit Purchase Price. The Board of Managers shall determine whether to refuse or admit any such Third Party to the Company and such determination shall be
conclusive and binding upon the Company and the Members. Each Third Party offeree that the Board of Managers determines to admit as a Member shall become a Member and be reflected as such on the records of the Company at such time as such individual
or entity (i) makes the representations set forth in Section 3.7 of this Agreement, (ii) subject to Section 3.4(d), pays the Company cash in the amount of the portion of the Additional Units Purchase Price payable upon admission
that is allocable to the Additional Units to be acquired by such Third Party, (iii) executes and delivers a counterpart of this Agreement or an instrument of joinder to this Agreement that is approved by the Board of Managers, and
(iv) performs or satisfies such other conditions as the Board of Managers may in its absolute discretion deem appropriate. 

(d)    The “Additional Unit Purchase Price” and the Percentage Interest to be assigned to the Additional
Investor Unit shall each be based on the fair market value of the Additional Investor Unit, as determined by the Board of Managers in its reasonable discretion on 

  
 15 













 
the date of its decision to issue Additional Units on the basis of its determination of the fair market value of the assets of the Company and the Percentage Interests of the Members, subject to
Section 3.4(f). The Additional Unit Purchase Price shall be payable in cash at the time of the issuance of the Additional Units and/or in installments and at times as determined by the Board of Managers in its absolute discretion. 

(e)    Upon the issuance of any Additional Units, the Board of Managers is authorized to reflect the Capital Contributions
of each of the additional Members and to restate the Percentage Interests of each of the Members. Upon the issuance of any Additional Units, the Board of Managers is authorized to restate the Capital Accounts of the Members to reflect their
respective shares of the fair market value of the assets of the Company as determined pursuant to this Section 3.4. 

(f)    The determinations of the fair market value of the Additional Units and of the deemed fair market value of the
Company described in this Section 3.5 shall lie within the reasonable discretion of the Board of Managers, it being recognized by the Members that there will be no market for the Units. 

3.5    Other Matters Relating to Capital Contributions. 

(a)    Loans by a Member to the Company shall not be considered Capital Contributions. 

(b)    Subject to Article X and subject to Section 2.4, no Member shall be entitled to withdraw, or to obtain a
return of, any part of his contribution to the capital of the Company, or to receive Company property or assets other than cash in return thereof, and no Member shall be liable to any other Member for a return of his contributions to the capital of
the Company. 
 (c)    No Member shall be entitled to priority over any other Member, either with respect to a return of
his contributions to the capital of the Company, or to allocations of taxable income, gains, losses or credits, or to distributions, except as provided in this Agreement. 

(d)    No interest shall be paid on any Member’s Capital Contribution. 

(e)    Subject to Article X, the Board of Managers shall have no liability to any Member to return such Member’s
Capital Contribution. 
 3.6    Deficit Capital Account Balances. Upon liquidation of a Member’s Company
Interest, no Member with a deficit balance in its Capital Account shall have any obligation to restore such deficit balance, or to make any contribution to the capital of the Company. 

3.7    Investment Representation of Members. Each Member represents and warrants to, and agrees with, the Company
as follows: 
 (a)    that such Member is acquiring its Company Interest for its own account solely for investment and
not with a view to distribution thereof; 

  
 16 













 (b)    that such Member has participated in the development of the
business plan of the Company, is fully familiar with the risks and opportunities associated with an investment in the Company and is not relying on the other Member(s) in making a decision to invest in the Company; 

(c)    that such Member understands that the Company Interests have not been registered under the Securities Act or the
securities statutes of any state, and accordingly may not be sold, transferred, pledged, hypothecated or otherwise disposed of without first complying with the provisions of Section 9.2(e) hereof; 

(d)    that such Member shall indemnify and hold the Company harmless from and against all of the costs and expenses,
including reasonable attorneys’ fees, incurred by the Company as a result of such Member’s breach of the provisions of this Section 3.7 or any other breaches of written representations or warranties made for purposes of complying with
applicable federal or state securities laws; and 
 (e)    that, where applicable, such Member has delivered a true and
correct form of a Certificate of Non-Foreign Status, attached as Exhibit E. 

3.8    Liability of Members. The liability of each Member for the losses, debts, liabilities and obligations of the
Company shall be limited to his, her or its obligations to make Capital Contributions as contemplated hereby and to his, her or its share of any assets and undistributed profits of the Company; provided, however, that under applicable law a Member
may be liable under certain circumstances to the extent of previous money or other distributions made to him, her or it. It is the intention of this Agreement that no Member shall have any liability as a result of the receipt of any distribution
except to the express extent provided in Sections 18-804(c) and (d) of the Act. No Member shall be required to lend any funds to the Company or, after his, her or its entire Capital Contribution required
to be paid hereunder has been paid, to make any further contribution to the Company. It is the intent of the Members that no distribution (or any part of any distribution) made to any Member pursuant to Section 7.1 hereof shall be deemed a
return or withdrawal of such Member’s Capital Contribution for purposes of the Act, even if such distribution represents, in full or in part, an allocation of depreciation or any other non-cash item
accounted for as a loss or deduction from or offset to the Company’s income, and that no Member shall be obligated to pay any such amount to or for the account of the Company or any creditor of the Company. If any court of competent
jurisdiction holds, however, that, notwithstanding the provisions of this Agreement, any Member is obligated to make any such payment, such obligation shall be the obligation of such Member and not of the Board of Managers. Nothing in this
Section 3.9 shall limit or restrict any liability that Renalytix would otherwise have pursuant to the ASA, or any liability that ISMMS would otherwise have pursuant to the ISMMS IP License Agreement and/or the ISMMS TM License Agreement. 

3.9    Uncertificated Units. The Board of Managers shall act as registrar for the Units. At all times while any
Units remain outstanding, the Board of Managers shall keep or cause to be kept books of registry for the registration of Units and registration of transfer of Units at the Company’s principal place of business. Upon compliance with the terms
and conditions of Article IX hereof with respect to a Unit, the Board of Managers shall register the transfer of such Units. Prior to the due presentment for registration of transfer, the Board of Managers may treat 

  
 17 













 the registered owner of any Units as the absolute owner of such Units for the purpose of making
distributions and for all other purposes whatsoever. Class A Profits Interests Units shall be considered “general intangibles” as such term is defined in Section 9-102(a)(42) of the Uniform
Commercial Code as adopted in the State of Delaware. 
 3.10    Loans to the Company. 

(a)    Any Member (the “Lending Member”) may lend funds to the Company on such terms as may be deemed reasonable
by the Board of Managers; provided, however, that the Board of Managers shall offer each other Member the right to participate in any such loan of funds to the Company upon the same terms as agreed upon with the Lending Member. 

(b)    Initial Loans. 

(i)    ISMMS hereby agrees to lend to the Company the aggregate amount of $750,000 (Seven Hundred Fifty
Thousand Dollars) (the “ISMMS Loan”), payable (i) $250,000 (Two Hundred Fifty Thousand Dollars) as of the date hereof, and (ii) the balance of the ISMMS Loan payable as and when called for by the Board of Managers (provided that each
such call for the ISMMS Loan shall be made by the Board of Managers upon all Initial Loans (as defined below) on a pro rata basis). When ISMMS has made an aggregate loan to the Company equal to $750,000 (Seven Hundred Fifty Thousand Dollars), ISMMS
shall have no further obligation to lend any funds to the Company except as ISMMS may agree in writing in its sole discretion. 

(ii)    Renalytix hereby agrees to lend to the Company the aggregate amount of $250,000 (Two Hundred Fifty
Thousand Dollars) (the Renalytix Loan” and together with the ISMMS Loan, the “Initial Loans”), payable (i) $83,333 (Eighty-Three Thousand Three Hundred Thirty-Three Dollars) as of the date hereof, and (ii) the balance of the
Renalytix Loan as and when called for by the Board of Managers (provided that each such call for the Renalytix Loan shall be made by the Board of Managers upon all Initial Loans on a pro rata basis). When Renalytix has made aggregate loan to the
Company equal to $250,000 (Two Hundred Fifty Thousand Dollars), Renalytix shall have no further obligation to lend any funds to the Company except as Renalytix may agree in writing in its sole discretion. 

(iii)    The Initial Loans will bear interest at 0.25%, compounded monthly, and will be repayable from the
first amounts that would otherwise constitute Available Cash for distribution to the Members of the Company (provided that the Loans will be repaid on a pro rata basis). The Initial Loans shall be issued pursuant to the terms of that certain
Promissory Note attached hereto as Exhibit F (the “Promissory Note”). 
 3.11    Renalytix Disqualifying
Event. Notwithstanding anything to the contrary contained herein, in the event that the ASA is terminated pursuant to Section 12.1(b)(iii) of the ASA, the parties hereby agree and acknowledge that the rights granted to Renalytix pursuant to
the Voting Agreement and Section 4.4(c) shall become null and void.

of the Members or their Affiliates otherwise existing at law or in equity, are agreed by the Members to replace such other duties and liabilities of such Person. 

(c)    Same Interests. Without limiting the generality of Section 4.12(a), in anticipation that the Company
and ISMMS may have an interest in the same areas of corporate opportunities, and in recognition of the benefits to be derived by the Company through its 

  
 24 













 continued contractual, corporate and business relations with ISMMS (including potentially service of
officers and trustees of ISMMS as Board Members of the Corporation), the provisions of this Section 4.12(c) are set forth to regulate and define the conduct of certain affairs of the Company as they may involve ISMMS and its officers and
trustees, and the powers, rights, duties and liabilities of the Company and its officers, Board Members and Members in connection therewith. 

(i)    Subject to any provisions herein to the contrary and in any negotiated commercial agreements to
which ISMMS is a party, ISMMS shall have the right to, and shall have no duty to refrain from, conducting and carrying on its business, activities and transactions and doing and performing all and everything which may be necessary, advisable or
suitable and proper for the conduct of its business. Neither ISMMS nor any officer or trustee thereof (except as provided in Section 4.12(c)(ii)) shall be liable to the Company or its Members for breach of any fiduciary duty by reason of any
such business, activities or transactions of ISMMS or of such person’s participation therein. In the event that ISMMS acquires knowledge of a potential transaction or matter which may be a corporate opportunity for both ISMMS and the Company,
ISMMS shall have no duty to communicate or present such corporate opportunity to the Company and shall not be liable to the Company or its Members for breach of any fiduciary duty as a Member of the Company by reason of the fact that ISMMS pursues
or acquires such corporate opportunity for itself, directs such corporate opportunity to another person or entity (including, without limitation, an Affiliate of ISMMS) or does not present such corporate opportunity to the Company. 

(ii)    In the event that a Board Member or officer of the Company who is also a trustee or officer of
ISMMS acquires knowledge of a potential transaction or matter which may be a corporate opportunity for both the Company and ISMMS, such Board Member or officer of the Company: (i) shall have fully satisfied and fulfilled such person’s
fiduciary duty to the Company and its Members with respect to such corporate opportunity; (ii) shall not be liable to the Company or its Members for breach of any fiduciary duty by reason of the fact that ISMMS pursues or acquires such
corporate opportunity for itself or directs such corporate opportunity to another person or does not present such corporate opportunity to the Company; (iii) shall be deemed to have acted in good faith and in a manner such person reasonably
believes to be in and not opposed to the best interests of the Company for the purposes of this Agreement; and (iv) shall be deemed not to have breached such person’s duty of loyalty to the Company or its Members or to have derived an
improper personal benefit therefrom for the purposes of this Agreement, if such trustee or officer acts in good faith in a manner consistent with the following policy: 

(A)    a corporate opportunity offered to any person who is an officer of the Company and who is also a
trustee but not an officer of ISMMS shall belong to the Company, unless such opportunity is expressly offered to such person solely in his or her capacity as a trustee of ISMMS in which case such opportunity shall belong to ISMMS; 

  
 25 













 (B)    a corporate opportunity offered to any person
who is a Board Member but not an officer of the Company and who is also a trustee or officer of ISMMS shall belong to the Company only if such opportunity is expressly offered to such person solely in his or her capacity as a Board Member of the
Company and otherwise shall belong to ISMMS; and 
 (C)    a corporate opportunity offered to any person
who is an officer of both the Company and ISMMS shall belong to ISMMS unless such opportunity is expressly offered to such person solely in his or her capacity as an officer of the Company, in which case such opportunity shall belong to the Company.

 (iii)    For purposes of this Section 4.12(c), “corporate opportunities” shall include,
but not be limited to, business opportunities that the Company is legally and financially able to undertake, which are, from their nature, in the line of the Company’s business, are of practical advantage to it and are ones in which the Company
has an interest or a reasonable expectancy, and in which, by embracing the opportunities, the self-interest of ISMMS or its officers or trustees will be brought into conflict with that of the Company. 

(iv)    Any person or entity purchasing or otherwise acquiring any Units of the Company shall be deemed to
have notice of and consented to the provisions of this Section 4.12(c). 
 (v)    If any contract,
agreement, arrangement or transaction between the company and ISMMS involves a corporate opportunity and is approved in accordance with the procedures set forth in this Agreement, ISMMS and its officers and trustees shall also for the purposes of
this Section 4.12(c) and the other provisions of this Agreement: (i) have fully satisfied and fulfilled their fiduciary duties to the Company and its Members; (ii) be deemed to have acted in good faith and in a manner such persons
reasonably believe to be in and not opposed to the best interests of the Company; and (iii) be deemed not to have breached their duties of loyalty to the Company and its Members and not to have derived an improper personal economic gain
therefrom. Any such contract, agreement, arrangement or transaction involving a corporate opportunity not so approved shall not by reason thereof result in any such breach of any fiduciary duty or duty of loyalty or failure to act in good faith or
in the best interests of the Company or derivation of any improper personal benefit, but shall be governed by the other provisions of this Section 4.12(c), this Agreement, or the Act. 

(vi)    Notwithstanding anything in this Agreement to the contrary and in addition to any vote of the Board
of Managers required by this Agreement or the Act, until the occurrence of the first date on which ISMMS ceases to beneficially own Units entitled to twenty percent (20%) or more of the votes entitled to be cast by the Members, the affirmative vote
of at least seventy-five percent (75%) of the votes entitled to be cast thereon by the Members of the then outstanding Units of the Company shall be required to amend, alter or repeal, or adopt any provision inconsistent with, any provision of this
Section 4.12(c). 

  
 26 













 Neither the amendment, alteration, termination or repeal of this Section 4.12(c) nor
the adoption of any provision inconsistent with this Section 4.12(c) shall eliminate or reduce the effect of this Section 4.12(c) in respect of any matter occurring, or any cause of action, suit or claim that, but for this
Section 4.12(c), would accrue or arise, prior to such amendment, alteration, termination, repeal or adoption. 

(vii)    Neither the alteration, amendment, termination, expiration or repeat of this Section 4.12(c)
nor the adoption of any provision inconsistent with this Section 4.12(c) shall eliminate or reduce the effect of this Section 4.12(c) in respect of any matter occurring, or any cause of action, suit or claim that, but for this
Section 4.12(c), would accrue or arise, prior to such alteration, amendment, termination, expiration, repeal or adoption.

Section 4.12, in anticipation that the Company and ISMMS may enter into contracts or otherwise transact business with each other and that the Company may derive benefits therefrom, the provisions of this Section 4.12(d) are set forth to
regulate and define certain contractual relations and other business relations of the Company as they may involve ISMMS, and the powers, rights, duties and liabilities of the Company in connection therewith. The provisions of this
Section 4.12(d) are in addition to, and not in limitation of, the provisions of the Act and the other provisions of this Agreement. Any contract or business relation that does not comply with the procedures set forth in this
Section 4.12(d) shall not by reason thereof be deemed void or voidable or result in any breach of any fiduciary duty or duty of loyalty or failure to act in good faith or in the best interests of the Company or derivation of any improper
personal economic gain, but shall be governed by the provisions of this Agreement, the Act, and other applicable law. 

(i)    No contract, agreement, arrangement or transaction between the Company and ISMMS (including without
limitation the ISMMS IP License Agreement and the ISMMS TM License Agreement) shall be void or voidable solely for the reason that ISMMS is a party thereto or a contract or agreement has been executed by an officer or trustee of ISMMS who is also an
officer or a Board Member of the Company, and ISMMS (i) shall have fully satisfied and fulfilled its fiduciary duties to the Company and its Members with respect thereto; (ii) shall not be liable to the Company or its Members for any
breach of fiduciary duty by reason of the entering into, performance or consummation of any such contract, agreement, arrangement or transaction; (iii) shall be deemed to have acted in good faith and in a manner it reasonably believed to be in
and not opposed to the best interests of the Company for purposes of this Agreement; and (iv) shall be deemed not to have breached its duties of loyalty to the Company and its Members and not to have derived an improper personal benefit
therefrom for the purposes of this Agreement, if: 
 (A)    the material facts as to the contract,
agreement, arrangement or transaction are disclosed or are known to the Board of Managers or the committee thereof that authorizes the contract, agreement, arrangement or transaction, 

  
 27 













 and the Board of Managers or such committee in good faith authorizes the contract,
agreement, arrangement or transaction by the affirmative vote of a majority of the disinterested Board Members, even if the disinterested Board Members constitute less than a quorum, if such contract, agreement, arrangement or transaction has been
approved by a Supermajority Vote as contemplated by Section 4.4(c); 
 (B)    the material facts as
to the contract, agreement, arrangement or transaction are disclosed or are known to the holders of Units entitled to vote thereon, and the contract, agreement, arrangement or transaction is specifically approved in good faith by the affirmative
vote of the holders of a majority of the votes entitled to be cast thereon, except Units that are beneficially owned or the voting of which is controlled by ISMMS or one of its Affiliates; or 

(C)    the transaction, judged according to the circumstance at the time of the commitment, is established
to have been fair to the Company. 
 (ii)    Board Members of the Company who are also trustees or
officers of ISMMS may be counted in determining the presence of a quorum at a meeting of the Board of Managers or of a committee that authorizes the contract, agreement, arrangement or transaction. Units owned by ISMMS may be counted in determining
the presence of a quorum at a meeting of Members that authorizes the contract, agreement, arrangement or transaction. 

(iii)    Any person or entity purchasing or otherwise acquiring any interest in any Units of the Company
will be deemed to have notice of and to have consented to the provisions of this Section 4.12(d). 

(iv)    For purposes of this Section 4.12(d), any contract, agreement, arrangement or transaction with
any corporation, partnership, joint venture, limited liability company, trust, association or other entity in which the Company owns (directly or indirectly) fifty percent (50%) or more of the outstanding voting stock, voting power, partnership
interests or similar ownership interests, or with any officer or director thereof, shall be deemed to be a contract, agreement, arrangement or transaction with the Company. 

(v)    Notwithstanding anything in this Agreement to the contrary and in addition to any vote of the Board
of Managers required by this Agreement or the Act, the affirmative vote of at least seventy-five percent (75%) of the votes entitled to be cast thereon by the holders of the then outstanding Units of the Company shall be required to alter, amend or
repeal, or adopt any provision inconsistent with, any provision of this Section 4.12(d). Neither the alteration, amendment or repeal of this Section 4.12(d) nor the adoption of any provision inconsistent with this Section 4.12(d)
shall eliminate or reduce the effect of this Section 4.12(d) in respect of any matter occurring, or any cause of action, suit or claim that, but for this Section 4.12(d), would accrue or arise, prior to such alteration, amendment, repeal
or adoption. 

  
 28 













 (e)    Conduct of Certain Company Affairs. Without limiting the
generality of the foregoing provisions of this Section 4.12, in anticipation that ISMMS will remain a Member of the Company and may have continued contractual, corporate and business relations with the Company, the provisions of this
Section 4.12(e) are set forth to regulate and define the conduct of certain affairs of the Company as they may impact ISMMS and its legal and regulatory status. 

(i)    the Company shall not, without the written consent of ISMMS, engage, directly or indirectly, in any
act or activity which would result, either alone or after giving effect to the business, operations, properties, activities and legal and regulatory status of ISMMS and the Company, in: (i) ISMMS being required to file any notice, report or
other document or make any registration with, obtain any approval, consent or authorization of or otherwise become subject to any statutes, rules, regulations, ordinances, orders, decrees or other legal restrictions of any federal, state, local or

also a trustee or officer of ISMMS being ineligible to serve or prohibited from serving as a Board Member of the Company or trustee or officer of ISMMS under or pursuant to any Applicable Law. ISMMS shall not be liable to the Company or its Members
for breach of any fiduciary duty by reason of the fact that ISMMS gives or withholds any consent for any reason in connection with this Section 4.12(e). No vote cast or other action taken by any person who is an officer, trustee or other
representative of ISMMS which vote is cast or action is taken by such person in his or her capacity as a Board Member of the Company shall constitute a consent of ISMMS for the purpose of this Section 4.12(e).

be deemed to have notice of and to have consented to the provisions of this Section 4.12(e).

Board of Managers required by this Agreement or the Act, the affirmative vote of the holders of at least seventy-five percent (75%) of the votes entitled to be cast thereon by the holders of the then outstanding Units of the Company shall be
required to alter, amend or repeal, or adopt any provision inconsistent with, any provision of this Section 4.12(e). Neither the alteration, amendment or repeal of this Section 4.12(e) nor the adoption of any provision inconsistent with
this Section 4.12(e) shall eliminate or reduce the effect of this Section 4.12(e) in respect of any matter occurring, or any cause of action, suit or claim that, but for this Section 4.12(e), would accrue or arise, prior to such
alteration, amendment, repeal or adoption. 
 4.13    Member Rights. The Members in their capacities as such will
not have any voting or approval rights with respect to the management of the Company. 

  
 29 













 4.14    Exculpation of Certain Member Liability. Notwithstanding
any other provision to the contrary contained in this Agreement, no Member, nor any Representative of a Member shall be liable, responsible, or accountable in damages or otherwise to the Company or any other Member or their Representatives, for any
loss, damage, cost, liability or expense incurred by reason of or caused by any act or omission performed or omitted by such Member or Representative whether based upon or arising from errors in judgment or breach of duty (including breach of any
duty of care or duty of loyalty) as a Member or Representative thereof, unless such Member shall be guilty of (i) willful or intentional misconduct in the performance of such Member’s duties to the Company or the other Members hereunder,
or (ii) such Member’s having improperly received personal benefit, or (iii) material breach of this Agreement or (iv) such Member’s failing to conduct itself with good faith and fairness in its dealing with the Company or

Agreement, (y) by reason of any action or omission based upon the advice of legal counsel or otherwise undertaken in good faith or in a manner reasonably believed by such person to be either in or not opposed to the Company’s best
interest, or (z) for any misconduct or negligence on the part of any agents appointed by such person in good faith. Nothing in this Section 4.14 shall apply to limit any responsibility of (a) Renalytix under and pursuant to the ASA,

ISMMS is hereby designated the Partnership Representative for the Company and it will serve in such capacity for so long as it is a Member of the Company and shall act as “tax matters partner” of the Company, with the same duties and

 CERTAIN MEMBER
MATTERS 
 6.1    Limitation of Liability of Members. Except as otherwise provided in the Act or by other
applicable law, no Member shall be bound by, or personally liable for, the obligations or liabilities of the Company, and no Member shall be required to contribute any capital to the Company other than such Member’s Capital Contributions and
agreed-upon Mandatory Additional Capital Contributions (if any). In voting its Units, a Member shall be entitled to take account of its own interests in lieu of those of the Company, and in no event shall any Member have any liability to the Company

6.2    Death, Bankruptcy, Etc. In no event shall the death, incompetency, bankruptcy, insolvency or other
incapacity of a Member operate to dissolve the Company. 
 6.3    Encumbrance of Member’s
Interest. Any Member may pledge, mortgage, hypothecate or otherwise encumber his, her or its Company Interest for any purpose whatsoever as long as such pledge, mortgage, hypothecation or other encumbrance shall in no manner entitle any assignee
or successor Member, in this regard either before or after foreclosure, to admission as a substituted Member. 

6.4    Tag-Along Rights. 

  
 32 













 (a)    So long as this Agreement remains in effect, if any Member
proposes to transfer any Units to a Third Party as a result of which a Change of Control would result from such transfer (the “Selling Member”), the Selling Member will have the obligation, and each of the other Members will have the
right, to require the proposed transferee or acquiring Person to purchase from each of the other Members who exercises its rights under Section 6.4(b) (a “Tagging Member”) a number of Units determined by multiplying the percentage of
the Selling Member’s Units being sold to such Third Party (a “Proposed Transferee”) by the number of Units owned by such Tagging Member. In each case, the sale of the Tagging Member’s Company Interest shall be upon the same terms
and conditions (including, without limitation, time of payment and form of consideration) as govern the proposed Transfer the Selling Member (as applicable), except that the purchase price of the Company Interest of each Tagging Member to be sold
under this Section 6.4(a) shall be the amount that would be received by such Tagging Member pursuant to Section 7.5 of this Agreement if (x) the Company sold all of its assets for a gross purchase price equal to the Enterprise Value
of the Company, and (y) the proceeds from such hypothetical sale were applied to the payment of the Company’s liabilities and distributions to the Members in accordance with Section 7.5. In order to be entitled to exercise its right
to sell shares of Company Interests to the Proposed Transferee pursuant to this Section 6.4(a), each Tagging Member must agree to make to the Proposed Transferee the same covenants, indemnities (with respect to all matters other than the
Selling Member’s ownership of Company Interests and representations relating solely to the business of the Company and not the Company Interests being sold) and agreements as the Selling Member agrees to make in connection with the Transfer and
such representations and warranties (and related indemnification) as to its ownership of its Company Interests as are given by the Selling Member with respect to such party’s ownership of Company Interests; provided, that all such covenants,
indemnities and agreements shall be made by the Tagging Members severally and not jointly and that the liabilities thereunder (other than with respect to the ownership of each Member’s shares being transferred, which shall be several
obligations) shall be borne on a pro rata basis based on the Company Interests Transferred by each of the Selling Member and the Tagging Members. Each Tagging Member will be responsible for its proportionate share of the reasonable out-of-pocket costs incurred by the Selling Member in connection with the proposed sale to the extent not paid or reimbursed by the Company or the Proposed Transferee. 

(b)    The Selling Member will give notice to each Tagging Member of each proposed sale at least 15 business days prior to
the proposed consummation of such sale, setting forth the Company Interests proposed to be so Transferred, the name and address of the Proposed Transferee, the proposed amount and form of consideration and the calculation of the consideration and
enterprise value which calculation is subject to the reasonable approval of the Tagging Member (and if such consideration consists in part or in whole of property other than cash, the transferring member will provide such information, to the extent
reasonably available to it, relating to such consideration as the Tagging Member may reasonably request in order to evaluate such non-cash consideration) and other terms and conditions of payment offered by
the Proposed Transferee. The tag-along rights provided by this Section 6.4(b) must be exercised by each Tagging Member within fifteen (15) business days following receipt of the notice required by
the preceding sentence and the agreement on the calculation of the consideration, if applicable, by delivery of an irrevocable written notice to the transferring member indicating such Tagging Member’s exercise of its, her or his rights and
specifying the maximum Company Interests it, she or he desires to sell. The Tagging Member will be entitled under this Section 6.4(b) to Transfer to the Proposed Transferee the Company Interests determined in accordance with
Section 6.4(a). 

  
 33 













 (c)    If any Tagging Member exercises its, her or his rights under
Section 6.4(b), the closing of the purchase of the Company Interests with respect to which such rights have been exercised is subject to, and will take place concurrently with, the closing of the sale of the Selling Member’s Company
Interests to the Proposed Transferee. 
 6.5    Drag Along Rights. 

(a)    Subject to the last sentence hereof, if a Member receives an offer from a Third Party that would constitute a Change
of Control (whether via an equity purchase, merger or otherwise) and such offer is accepted (the Member in such capacity, the “Dragging Party”), then each of the other Members hereby agrees that, if requested by the Dragging Party, it will
Transfer to such Third Party on the same terms and conditions (including, without limitation, time of payment and form of consideration) as to be paid and given to the Dragging Party, a number of Units determined by multiplying the percentage of the
Dragging Members Units being sold to the Proposed Transferee by the number of Units owned by such Tagging Member. The sale of the other Members’ Company Interests shall be upon the same terms and conditions (including, without limitation, time
of payment and form of consideration) as govern the proposed Transfer by the Dragging Party, except that the purchase price of the Company Interest of each other Member to be sold under this Section 6.5(a) shall be the amount that would be
received by such Member pursuant to Section 7.5 of this Agreement if (x) the Company sold all of its assets for a gross purchase price equal to the Enterprise Value of the Company, and (y) the proceeds from such hypothetical sale were
applied to the payment of the Company’s liabilities and distributions to the Members in accordance with Section 7.5. 

(b)    The Dragging Party that received the initial offer will give notice (the “Drag-Along Notice”) to each of
the other Members of any proposed Transfer giving rise to the rights of the Dragging Party set forth in Section 6.5(a) as soon as practicable following the acceptance of the offer referred to in Section 6.5(a). The Drag-Along Notice will
set forth the Units proposed to be so Transferred, the name of the Proposed Transferee or acquiring Person, the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the
Dragging Party providing the Drag-Along Notice will provide such information, to the extent reasonably available to the Dragging Party, relating to such consideration as the other Members may reasonably request in order to evaluate such non-cash consideration), the Company Interests (of each class) sought and the other terms and conditions of the offer. The Dragging Party providing the Drag-Along Notice will notify the other Members at least
fifteen (15) business days in advance of the closing of the sale of Company Interests to the Third Party. In any such agreement, such other Members will be required (i) to make or agree to the same covenants, indemnities (with respect to
all matters other than the Dragging Party’s ownership of Company Interests and representations relating solely to the business of the Company and not the Company Interests being sold) and agreements as the Dragging Party so long as they are
made severally and not jointly and the liabilities thereunder are borne on a pro rata basis based on the Company Interests Transferred by each Member, and (ii) to make representations and warranties (and provide related indemnification) as to
their ownership of their Company Interests as are given by the Dragging Party with respect to such 

  
 34 













 party’s ownership of Company Interests, provided, however, that (x) any such agreement shall
expressly provide that in no event shall the liability of any Member pursuant to such agreement exceed the amount of the purchase price actually received by such Member pursuant to such agreement, and (y) no Member (other than a Member that is
or was an employee of the Company or its subsidiaries) shall be required to enter into or agree to be bound by any restrictive covenant that would obligate such Member not to engage in any business activity that is competitive with that of the
Transferee. The Company shall pay all costs incurred in connection with a sale under this Section 6.5. If the Transfer referred to in the Drag-Along Notice is not consummated within ninety (90) days from the date of the Drag-Along Notice,
the Dragging Party must deliver another Drag-Along Notice in order to exercise its rights under this Section 6.5(b) with respect to such Transfer or any other Transfer. 

(c)    In order to secure the obligation of each of the Members to comply with this Section 6.5, and for other good
and valuable consideration, each of the Members hereby appoints ISMMS (the “Proxy”), as its true and lawful proxy and attorney-in-fact, with full power of
substitution, to take such actions as may be reasonably necessary hereunder to fulfill the obligations of such Member in accordance with the terms of this Section 6.5. The Proxy may exercise the irrevocable proxy granted to it hereunder at any
time any Member fails to comply with the provisions of this Section 6.5 within five (5) business days after the date on which the Proxy gives notice to such Member demanding that such Member execute documentation that is in accordance with
this Section 6.5, provided that, if within such five (5) business day period such Member gives notice to the Proxy that such documentation is not in accordance with this Section 6.5 specifying the respects in which such documentation
is not in accordance with this Section 6.5, then the Proxy shall not have the authority to execute such documentation on behalf of such Member. The proxies and powers granted by each of the Members pursuant to this Section 6.5 are coupled
with an interest and are given to secure the performance of its obligations to the Company under this Agreement. Such proxies and powers will be irrevocable for the term of this Agreement. 

ARTICLE VII 
 ALLOCATIONS AND
DISTRIBUTIONS 
 7.1    Distributions of Available Cash. 

(a)    The Board of Managers shall distribute Available Cash from Operations when the Board of Managers in its discretion
determines that such Available Cash is available for distribution. Any Available Cash shall be distributed to the Members in accordance with their respective Percentage Interests as of the date of distribution. 

(b)    The Board shall approve a Distribution by April 5 of each year to each Member of an amount at least equal to
the federal, state and local income taxes that would be payable by a corporation subject to tax in New York City with respect to the income of the Company allocated to such Member with respect to the preceding calendar year assuming each such Member
is taxed at the highest federal, state and local effective marginal income tax rate applicable to any Member, provided, however, that (i) such amount shall be reduced by the amount of any prior distributions to such Member with respect to such
calendar year and by any 

  
 35 













 losses of the Company previously allocated to such Member which have not been taken into account in
determining the federal, state and local income taxes payable by such Member with respect to the income of the Company and (ii) such amount shall not exceed the amount of Available Cash from Operations as of the date of Distribution. Any
distribution to any Member pursuant to this Section 7.1(b) shall be credited against the entitlement of such Member to distributions pursuant to Section 7.1(a). 

7.2    Allocations of Net Income and Gain. Except as provided in Section 7.5: 

(a)    items of income and gain from other than from a Liquidating Event shall be allocated to the Members as follows:

 (i)    first, to the Members having deficits in their Capital Accounts in excess of their respective
shares of Company Minimum Gain in the ratio of such excess deficits until such excess deficits are eliminated; 

(ii)    next, to the Members in the ratio of, and in an aggregate amount not to exceed, the amounts of
Available Cash from Operations distributed to them in such fiscal year and in prior fiscal years to the extent not previously matched by an allocation of income pursuant to this Section 7.2(a)(ii); and 

(iii)    finally, to the extent of any remaining income or gain, to the Members in accordance with the
manner in which Available Cash from Operations would be distributed to the Members if an amount of Available Cash from Operations equal to such remaining income were available for distribution. 

(b)    items of income and gain from a Liquidating Event shall be allocated, after giving effect to all other allocations
and distributions for the fiscal year in which such Liquidating Event occurs, as follows: 

(i)    first, to the Members having deficits in their Capital Accounts in the ratio of such deficits until
such deficits are eliminated; 
 (ii)    next, to the Members as necessary to cause the balances in their
Capital Accounts to be as nearly as possible in the same ratio as they would need to be to result in each Member receiving total distributions from the Company, on a cumulative basis as if all distributions, including liquidating distributions, were
made in the manner provided for Available Cash under Section 7.1 hereof. 
 7.3    Allocation of Losses.
Except as provided in Section 7.4, all items of loss for each fiscal year of the Company shall be allocated: 

(i)    first, to the Members in a manner so that the Capital Accounts of the Members have balances which
are as close as possible to the total distributions each Member would receive in the manner provided in Section 7.1 above as if the Company were liquidated at the end of such fiscal year (assuming solely for the purpose of this allocation that
there would be no additional gain or loss on liquidation of the Company); and 

  
 36 













 (ii)    next, to the Members in the ratio of their
Percentage Interests as of the last day of such fiscal year. 
 7.4    Minimum Gain and Qualified Income Offset.

 (a)    Definitions. The following terms shall have the meanings set forth below: 

(i)    “Company Minimum Gain” has the meaning set forth in Treasury Regulation Section 1.704-2(b)(2) for the phrase “partnership minimum gain”. 

(ii)    “Nonrecourse Debt” has the meaning described in Treasury Regulation Section 1.704-2(b)(3) for the phrase “nonrecourse liability”. 

(iii)    “Nonrecourse Deduction” has the meaning described in Treasury Regulation Section l.704-2(b)(1). 
 (iv)    “Adjusted Capital Account Balance”
means, as to any Member, the sum of such Member’s Adjusted Capital Account Balance increased by such Member’s share of Company Minimum Gain and such Member’s minimum gain attributable to Member Nonrecourse Debt. 

(v)    “Member Nonrecourse Debt” shall have the meaning ascribed thereto in Treasury Regulations Section 1.704-2(b)(4) for the phrase “partner nonrecourse debt”. 

(b)    Company Minimum Gain Chargeback. Notwithstanding anything contained in this Article VII to the contrary, if
there is a net decrease in Company Minimum Gain during any taxable year of the Company, except as otherwise permitted by Treasury Regulation Section 1.704-2(f)(2), (3), (4) and (5), items of Company
income and gain for such taxable year (and subsequent years, if necessary) in the order provided in Treasury Regulation Section 1.704-2(j)(2)(i) shall be allocated among all Members whose shares of
Company Minimum Gain decreased during that year in proportion to and to the extent of such Member’s share of the net decrease in Company Minimum Gain during such year. The allocation contained in this Section 7.4(b) is intended to be a
minimum gain chargeback within the meaning of Section 1.704-2 of the Treasury Regulations, and shall be interpreted consistently therewith. 

(c)    Qualified Income Offset Provision. Notwithstanding anything else to the contrary contained in this
Agreement, to the extent the allocation of any loss or deduction would cause any Member to have a deficit Adjusted Capital Account Balance, such Member will not be allocated a loss or deduction which will cause or increase such Member’s deficit
Adjusted Capital Account Balance in excess of any dollar amount of such deficit balance that the Member is obligated to restore upon liquidation, as of the end of the Company’s taxable year to which such allocation relates. For purposes of this
Section 7.4(c), the Capital Account of each Member shall be reduced (i) for any distributions that, as of the end of such year, reasonably are expected 

  
 37 













 to be made to such Member to the extent they exceed offsetting increases to such Member’s Capital
Account that reasonably are expected to occur during (or prior to) the Company taxable years in which such distributions reasonably are expected to be made, (ii) adjustments that as of the end of such year reasonably are expected to be made for
depletion adjustments, and (iii) allocations that, as of the end of such year, reasonably are expected to be made pursuant to Code Section 704(e)(2) (dealing with purchases of interests by family members), Code Section 706(d) (dealing
with changes in Members’ interests) and Treasury Regulations Section 1.751-1 (dealing with unrealized receivables and inventory items), all as described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d). A Member who unexpectedly receives an adjustment, allocation or distribution described immediately above which causes or increases such Member’s deficit Adjusted Capital
Account Balance (in excess of any dollar amount of such deficit balance that such Member is obligated to restore upon liquidation, as of the end of the Company’s taxable year to which such allocation relates), will be allocated items of income
and gain in an amount and manner sufficient to eliminate such deficit balance as quickly as possible. 
 To the extent this
Section 7.4(c) prevents the allocation of a deduction or loss to a Member, such deduction or loss shall be allocated among the Members in accordance with their interests in the Company as determined under Treasury Regulations Section 1.704-1(b)(3). 
 This Section 7.4(c) is intended to constitute a “qualified income
offset” within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be so interpreted and applied. 

7.5    Distributions Upon Liquidation of Company. 

(a)    Upon liquidation (as defined in Section 7.5(c) hereof) of the Company, the assets of the Company shall be
distributed no later than the later of 90 days after the date of such liquidation or the end of the Company’s taxable year in which the liquidation occurs and shall be applied in the following order of priority: 

(i)    first, to the creditors of the Company (including Members or former Members who are creditors, to
the extent permitted by law) in accordance with Section 18-804 of the Act; 

(ii)    next, subject to Treasury Regulations
Section 1.704-1(b)(2)(ii)(b), to set up any reserves which the Board of Managers deems reasonably necessary for contingent or unforeseen liabilities or obligations of the Company arising out of or in
connection with the business of the Company; and 
 (iii)    thereafter, after all Capital Account
adjustments for the Company’s taxable year in which the liquidation occurs (including without limitation adjustments required under Treasury Regulations Section 1.704-1(b)(2)(iv)(e)), relating to
distributions in kind), to the Members in accordance with Section 7.1(a). 
 (b)    [Reserved] 

  
 38 













 (c)    For purposes of this Section 7.5, a liquidation of the
Company shall occur upon the earlier of: 
 (i)    the date on which the Company is terminated under
Section 708(b)(1) of the Code; 
 (ii)    the date upon which the Company is terminated under
Article X; and 
 (iii)    the date upon which a Liquidating Event occurs (and all payments, including
payments on any promissory notes, have been received). 
 7.6    Additional Tax Allocation Provisions. 

(a)    Notwithstanding anything to the contrary contained in this Agreement, and as stated in Treasury Regulations Section 1.704-1(b)(4)(i), when any property of the Company is reflected in the Capital Accounts of the Members and on the books of the Company at a book value that differs from the adjusted tax basis of such
property, then certain book items with respect to such property will differ from certain tax items with respect to that property. Since the Capital Accounts of the Members are required to be adjusted solely for allocation of the book items, the
Members’ shares of the corresponding tax items are not independently reflected by adjustments to the Capital Accounts. Accordingly, items of income, gain, loss and deduction for tax purposes with respect to property, other than cash,
contributed to the Company by a Member or with respect to an adjustment to the Members’ Capital Accounts to reflect a revaluation of the property of the Company, shall be allocated among the Members so as to take into account the variation
between the basis of the contributed property to the Company and its fair market value at the time of contribution or, in the case of a revaluation of the property of the Company, so as to take into account the adjustments to the Members’
Capital Accounts as provided in Section 704(c) of the Code and Regulations thereunder and Treasury Regulations Sections 1.704-1(b)(2)(iv)(f) and
1.704-1(b)(2)(iv)(g). 
 (b)    As between a Member who has Transferred all or
part of his, her or its Company Interest and its transferee, all items of income, gain, deduction and loss, for any year shall be apportioned on the basis of the number of days in each such year that each was the holder of such Company Interest
(making adjustments necessary to comply with the provisions of Section 706(d)(2) of the Code), without regard to the results of the Company’s Operations during the period before and after the date of such transfer, provided that if both
the transferor and transferee consent thereto a special closing of the books shall be had as of the effective date of such transfer and the apportionment of items of income and gain, and deduction and loss, shall be made on the basis of actual
operating results, and provided further that in the case of a dilution of a Member’s Percentage Interest pursuant to Section 3.5, a special closing of the books shall be had as of the effective date of the dilution, and the apportionment
of items of income and gain and deduction and loss shall be made on the basis of actual operating results. Notwithstanding the above, gain or loss resulting from a Liquidating Event shall be allocated only to those persons who are Members as of the
date on which such transaction is consummated. 

  
 39 













 (c)    Depreciation recapture shall, to the extent possible, be
allocated to those Members to whom the corresponding depreciation deductions were allocated. 
 7.7    Intention of
Allocation Provisions. The purposes of the allocation provisions contained in Sections 7.2, 7.3, 7.4 and 7.6 are to properly reflect for book and tax purposes the rights of each of the Members to receive cumulative distributions throughout the
life of the Company and in the liquidation of the Company in a manner consistent with the provisions of Section 7.1, and, accordingly, such allocation provisions shall be interpreted, subject to any applicable tax law, in a manner which results
as closely as possible to such intended distribution scheme. 
 7.8    Restricted Payments. The Company and the
Board of Managers on behalf of the Company shall not make a distribution to a Member on account of his, her or its interest in the Company if such distribution would violate Section 18-607 of the Act or
other applicable law.

Company with the property and assets of any other party.

entitled to determine all federal income tax elections available to the Company.

withholding of tax is otherwise required, the Company shall deduct and withhold a tax at the applicable rate provided in the Code with respect to each Member who has not executed and delivered to the Company a Certification of Non-Foreign Status prior to the realization of such income. The Members shall timely supplement or re-execute the certifications as required by the Board of Managers or the
Internal Revenue Service. Each Member agrees to notify the Board of Managers of any change in its status within 60 days of such change. Such tax shall be withheld from distributions which otherwise would be made to such Member at the time of such
withholding; provided, however, that if no such distributions are to be made, or any such distributions are insufficient in amounts to satisfy such withholding obligation, such Member shall contribute to the Company an amount sufficient to satisfy
such obligation. 
 ARTICLE IX 

TRANSFERS 

9.1    Restriction on Transfers and Withdrawals. Except as otherwise provided in Sections 9.2, 9.3, 9.4, and 9.5 of
this Agreement, no Member may Transfer a Company Interest, in whole or in part, without the written consent of the Board of Managers. No transferee of a Company Interest shall be admitted as a substitute Member of the Company except as provided by
Section 9.6 (and any transferee not so admitted shall succeed only to the economic rights of his, her or its transferor). No Member may withdraw from the Company. This provision shall not apply to a withdrawal by ISMMS in connection with a
Jeopardy Event. 

  
 41 













 9.2    Transfers Requiring Consent. The following dispositions of
a Company Interest shall require the consent or compliance with the conditions stated below: 
 (a)    No Transfer of
any Company Interest in whole or in part will be permitted if it would cause the Company to be taxed other than as a partnership. Counsel for the Company may give its opinion to the Board of Managers as to whether or not such Transfer would cause
such a tax effect for federal income tax purposes and the opinion shall be conclusive and binding upon all Members. 

(b)    No transfer of the Class A Profits Interest Units issued to Renalytix shall be made without the consent of the
Board of Managers except that without the consent of the Board of Managers Renalytix shall have the right to transfer all or a portion of the Class A Profits Interest Units to (i) the 100% parent company of Renalytix or (ii) a
100%-owned subsidiary of Renalytix, provided that in either case no such transfer will relieve Renalytix of its obligations under this Agreement with respect to the transferred Units. 

(c)    ISMMS shall have the right to transfer all or a portion of the Class A Profits Interest Units to an Affiliate
of ISMMS without the consent of Renalytix, provided that no such transfer will relieve ISMMS of its obligations under this Agreement with respect to the transferred Units. 

(d)    ISMMS shall not transfer Class A Profits Interests such that a Change of Control would take place unless ISMMS
complies with the requirements of Section 6.4, Section 6.5 and Section 9.2. Subject to compliance with the requirements of Section 6.4, Section 6.5 and Section 9.2, ISMMS shall have the right to transfer its
Class A Profits Interest Units without the consent of Renalytix. 
 (e)    Unless waived in whole or in part by the
Board of Managers in its absolute discretion, no sale or exchange of a Company Interest may be made unless the transferee of such Company Interest provides the Company the following: 

(i)    an opinion of counsel, in form and substance satisfactory to counsel for the Company, which may
reasonably rely on representations and information supplied by the Board of Managers or the Company, that neither the offering nor the assignment of the Company Interest, or part thereof, to such transferee is required to be registered or qualified
pursuant to the provisions of federal or state securities laws, nor causes the loss of any exemption from federal or state securities laws which may be available to the Company Interests, nor violates the laws of any state whose laws apply to such
transfer, nor causes the Company to be taxed as a corporation rather than a partnership under the Code, nor causes the Company to be deemed an Investment Company or an affiliated or controlling person thereof under the Investment Company Act of
1940, nor causes the Company to be an Affiliate of, or causes the Manager, its employees or Affiliates to become fiduciaries of, an employee benefit plan subject to ERISA or the rules and regulations of the U.S. Department of Labor; 

  
 42 













 (ii)    a written representation of such transferee that
he, she or it is acquiring the Company Interest for his, her or its own account for investment and not with a view to distribution and such other representations and warranties as the Board of Managers may require in their absolute discretion to
ensure compliance with applicable federal and state securities laws; and 
 (iii)    payment of such
reasonable expenses as may be incurred by the Company in connection with such transferee’s admission as a Member. 

9.3    Permitted Sales after Right of First Refusal is Given. 

(a)    To the extent that such Transfer is permitted by Section 9.2 above, if a Member receives from a Third Party
(the “Offeror”) a bona fide offer (the “Offer”) in writing signed by the Offeror for the purchase of all or a part of such Member’s Company Interest or involving a transfer that would result in a Change of Control of such
Member (the “Offered Interest”), then the Selling Member, or the Controlling person or persons of such Member, who received such Offer shall, if it wishes to accept the Offer and prior to accepting such Offer or entering into a contract
with respect to such Offer, promptly forward a true and correct copy thereof to the Company within ten (10) days of the date of the Offer. The Company shall have the exclusive right and option for twenty (20) days following the receipt of
said Offer from the Selling Member (the “Company ROFR Notice Period”) to elect to purchase some or all of the Offered Interest on the terms and conditions set forth in the Offer. The Company shall exercise its option to purchase all, but
not less than all, of the Offered Interest and thereby accept the Offer of the Selling Member within the Company ROFR Notice Period by written notice of such election to the Selling Member. The Company shall be deemed to have elected not to purchase
the Offered Interest if it fails to timely provide written acceptance. If the Company elects to purchase the Offered Interest, then the closing of said purchase shall take place at the office of the Company. Any election to purchase shall be made
only upon the approval of the majority of the Board of Managers excluding the Board Member(s) affiliated with the Selling Member or the Offeror. 

(b)    If the Company does not elect to purchase all of the Offered Interest pursuant to Section 9.3(a), then Selling
Member shall promptly forward a true and correct copy of the Offer to the Class A Unit Holder if it is not the offeror (the “Non-Selling Member(s)”) within five (5) days of the end of the
Company ROFR Notice Period. The Offer shall be sent by certified or registered mail, return receipt requested. Each Non-Selling Member shall have the exclusive right and option for twenty (20) days
following the receipt of said Offer from the Selling Member (the “Non-Selling Member ROFR Notice Period”) to elect to purchase all, but not less than all, of the Offered Interest on the terms and
conditions set forth in the Offer. Each Non-Selling Member shall exercise its option to purchase the Offered Interest and thereby accept the Offer of the Selling Member by actual delivery to the Selling
Member, within the Non-Selling Member ROFR Notice Period, written notice of such election or by sending such written notice of election by certified or registered mail, return receipt requested, properly
stamped and addressed to the address of the Selling Member. Each Non-Selling Member shall be deemed to 

  
 43 













 have elected not to purchase the Offered Interest if it fails to timely provide written acceptance. Each Non-Selling Member who elects to so purchase the Offered Interest pursuant to the Offer (the “Electing Member”) shall have the right to purchase that proportion of the Offered Interest which the Percentage
Interest of such Electing Member bears to the total Percentage Interests of all Electing Members. The Electing Member shall be obligated to close no later than ninety (90) days after the date of the Offer. If the
Non-Selling Members elect to purchase the Offered Interest, then the closing of said purchase shall take place at the office of the Company. 

(c)    If the Non-Selling Members do not elect to purchase all of the Offered
Interest, the Selling Member may sell the Offered Interest to a Third Party; provided, however, that the sale (i) shall not be made at a price lower than the price offered to the Company and Non-Selling
Members, (ii) is not made to any person other than the original Offeror, (iii) is on the same terms and conditions as those specified in the Offer, and (iv) is consummated within ninety (90) days after the lapse of all options
arising in connection with the Offer. 
 (d)    If the Offeror or the terms or conditions of the proposed sale are
changed or the Offered Interest has not been sold prior to the lapse of the aforesaid period, the Selling Member must make a new Offer, pursuant to the procedures in this Section 9.3, to first the Company and then the Non-Selling Members prior to selling the Offered Interest. 
 9.4    Assumption by
Transferee. Any transferee to whom all or any part of a Company Interest may be transferred pursuant to this Agreement shall take such Company Interest subject to and be liable for all of the terms and conditions of this Agreement and any
unperformed obligations of the transferring Member under the terms of this Agreement (including, but not limited to, any obligation to make Capital Contributions) and shall not be considered to have title thereto until said transferee shall have
accepted and assumed the terms and conditions of this Agreement by a written agreement to that effect delivered to the other Members, at which time such transferee shall, subject to the provisions of Section 9.6 of this Agreement, be admitted
as a substitute Member and shall succeed to all rights of its transferor except as such rights may be otherwise limited by other provisions of this Agreement. Anything contained in this Section 9.4 to the contrary notwithstanding, the
assumption by the transferee of the Company Interest being transferred shall not relieve the transferor of such Company Interest of its obligations hereunder unless such transferor is released by written consent of the Board of Managers . 

9.5    Effect of Attempted Disposition in Violation of this Agreement. Any attempted Transfer of any Company
Interest in breach of this Agreement shall be null and void and of no effect whatsoever. 
 9.6    Substitute
Member. Notwithstanding the terms of this Article IX, no transferee of any Company Interest of a Member shall be admitted as a substitute Member without the prior written consent of the Board of Managers which consent may be granted or withheld
in the Board of Managers’ absolute discretion. 

  
 44 













 ARTICLE X 

DISSOLUTION 

10.1    Dissolution. 

(a)    It is the intention of the Members that the business of the Company be conducted pursuant to the provisions of this
Agreement, notwithstanding the occurrence of any event that would result in a statutory dissolution of the Company pursuant to the laws of the State of Delaware, and no Member shall be released or relieved of any duty or obligation hereunder by
reason thereof; provided, however, that the Company shall be dissolved, the business of the Company shall be terminated, its affairs wound-up and its property and assets distributed in liquidation on the
earlier to occur of: 
 (i)    the occurrence of a Liquidating Event; 

(ii)    a determination by the Board of Managers that the business of the Company should be terminated; or 

(iii)    the entry of a decree of judicial dissolution under Section 18-802
of the Act. 
 10.2    Wind-Up of Affairs. As expeditiously as possible
following the occurrence of an event giving rise to a liquidation or winding up of the Company, the Board of Managers (or a special liquidator who may be appointed by the Board if the termination or winding up results from the circumstance described
in Section 10.1(a)(iii) above) shall wind-up the affairs of the Company, sell its property and assets for cash at the highest price reasonably obtainable and distribute the proceeds, or distribute the
assets of the Company in kind, in accordance with Section 7.5 of this Agreement in liquidation of the Company. 
 ARTICLE XI 

INDEMNIFICATION 

11.1    Rights to Indemnification of Members and Representatives. 

(a)    The Company shall, to the fullest extent authorized or permitted by the Act as the same exists or may hereafter be
amended (but, in the case of any such amendment, only to the extent such amendment permits the Company to provide broader indemnification rights than permitted prior thereto), indemnify and hold harmless each member of the Board of Managers, each
Member and any Representative of a Member (whether such Member or Representative is acting on behalf of the Company or serving at the request of the Company as the Representative of another enterprise) (any such Member, or Representative or Member
being referred to herein as “Indemnitee”), against any and all expenses, liability and loss (including attorneys’ fees, judgments, fines, excise or other taxes or penalties) in connection with (including where such person is, was, or
is threatened to be made a defendant or respondent in) a threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative, arbitrative, or investigative, any appeal in such action, suit or proceeding and any


  
 45 













 inquiry or investigation that could lead to such an action, suit or proceeding (hereinafter a
“Proceeding”), by reason of the fact that such person was or is a Member or Representative thereof. The rights created by this Article XI shall continue as to an Indemnitee who has ceased to be a Member or Representative thereof and shall
inure to the benefit of an Indemnitee’s heirs, executors and administrators. 
 (b)    Without limiting any other
provisions of this Article XI, the Company shall pay or reimburse, and indemnify and hold harmless any Member and its Representatives against, expenses incurred by such person in connection with his appearances as a witness or other participation in
a Proceeding involving or affecting the Company at a time when such Member or its Representative is not a named defendant or respondent in the Proceeding. 

(c)    Without limiting any other provisions of this Article XI the provisions hereof shall for all applicable purposes of
the Act make mandatory any indemnification now or hereafter permitted or deemed permitted by the Act and shall constitute authorization of such indemnification to the fullest extent that authorization may be required for such indemnification
permitted thereby. Notwithstanding any other provision of this Article XI, any indemnification hereunder shall be provided out of and to the extent of Company assets only, and no Member (or Representative thereof) shall have personal liability on
account thereof. 
 (d)    Nothing in this Article XI shall apply to provide any right of indemnification (i) to
Renalytix in respect of any liability or obligation of Renalytix under or pursuant to the ASA, or (ii) to ISMMS in respect of any liability or obligation of ISMMS under or pursuant to the ISMMS IP License Agreement and/or the ISMMS TM License
Agreement. 
 11.2    Indemnification Procedures. 

(a)    Any person seeking indemnification pursuant to Section 11.1 (including any Advancement of Expenses as provided
in Section 11.3) shall be entitled to the procedures of this Section 11.2 for indemnification. 
 (b)    To
claim indemnification under this Article XI, an Indemnitee shall submit to the Company a written request for indemnification, including therein or therewith (or affirming that there will be made available to the Company) such documentation and
information as is reasonably available to the Indemnitee and as the Company may reasonably request to enable it make the determinations hereinafter provided for. If at the time of receipt of such request, the Company has in effect or is entitled to
claim reimbursement for such request under any policy of insurance covering such claim, the Company shall thereafter take proper action to cause such insurers to accept coverage and thereafter shall take all necessary action to cause such insurers
to pay such claim to or on behalf of the Indemnitee. 
 (c)    Upon any written request under subsection (a) above
by an Indemnitee for indemnification, if a determination is required by the Act (either (i) with respect to whether indemnification is permissible under the Act or (ii) as to the reasonableness of expenses for which indemnification is
requested), then in such event the Company shall proceed further (A) to notify the Indemnitee of such requirement (unless Indemnitee’s request shall confirm such fact), and (B) to make or cause to be made the determinations required
by the Act. The Indemnitee 

  
 46 













 and the Company shall cooperate with each other and the person or entity making such determination,
including providing upon reasonable advance request such information which is not privileged or otherwise protected from disclosure and which is reasonably necessary to such determination. 

(d)    Any “special legal counsel” selected to make any determination required under the Act shall be a law
firm, or member of a law firm, experienced in matters of corporation and limited liability company law and which neither presently is, nor in the past five (5) years has been, retained to represent the Company, the Indemnitee or any other party
to the Proceeding giving rise to the claim for indemnification, and shall not include any person who, under prevailing applicable standards of professional conduct, would have a conflict of interest with the Indemnitee or the Company or any other
party to the Proceeding. Any determination required by the Act, if the Indemnitee has so requested, (i) shall be made by special legal counsel reasonably satisfactory to the Indemnitee, and (ii) in the case of determination of
reasonableness of expenses, to the extent permitted by the Act, shall be determined by an independent, major national or international accounting firm which otherwise satisfies the requirements of this subsection (d). 

(e)    Notwithstanding the foregoing, no Indemnitee shall be indemnified and held harmless unless (i) it is
determined in accordance with the Act that the Indemnitee (A) acted in good faith, (B) reasonably believed that its conduct was in the best interests of the Company or at least not opposed to the best interests of the Company and
(C) in the case of a criminal proceeding, had no cause to believe that its conduct was unlawful, and (ii) the Indemnitee’s conduct did not constitute fraud, gross negligence, willful misconduct or breach of a contractual obligation or
duty on the part of the Indemnitee. The termination of any proceeding by judgment, order, settlement, conviction or on a plea of nolo contendere or its equivalent shall not alone determine that an Indemnitee did not meet the requirements set forth
in the preceding sentence. 
 (f)    An Indemnitee shall not be denied indemnification in whole or in part under this
Section 11.2 solely on the grounds that he, she or it had an interest in the transaction with respect to which the indemnification applies, if the transaction is one otherwise permitted to be carried out by the terms of this Agreement. 

(g)    Except as provided in Section 11.5 of this Agreement, the indemnification provided in this Article XI is
solely for the benefit of Indemnitees and shall not give rise to any right to indemnification in favor of any other persons. 

11.3    Advance Payment of Expenses. To the extent and under conditions approved by the Board of Managers, the
rights to indemnification conferred in this Article XI shall include the right to be paid by the Company the expenses incurred in defending any Proceeding in advance of its final disposition (an “Advancement of Expenses”). 

11.4    Right of the Indemnitee to Bring Suit. 

(a)    If a claim under Section 11.1 of this Agreement is not paid in full by the Company within sixty (60) days
after a written claim has been received by the Company, except 

  
 47 













 in the case of a claim for an Advancement of Expenses, in which case the applicable period shall be twenty
(20) days, an Indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the Company to recover an Advancement of
Expenses, the Indemnitee (or his, her or its Representative) shall also be entitled to be paid the expense of prosecuting or defending such suit. 

(b)    In any suit brought by an Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by
the Indemnitee to enforce a right to an Advancement of Expenses) it shall be a defense that (and in any suit by the Company to recover an Advancement of Expenses, the Company shall be entitled to recover such expenses upon a final adjudication that)
the Indemnitee has not met the requirements of the Act for indemnification; provided, however, that in any such suit, none of (i) the failure of the Company, its agents or legal representatives to have made a determination prior to the
commencement of such suit that indemnification of the Indemnitee is proper in the circumstances, because the Indemnitee has met the applicable requirements for indemnification, (ii) an actual determination by the Company, its agents or legal
representatives, that the Indemnitee has not met such applicable requirements, nor (iii) termination of any Proceeding by any judgment, order, settlement, or plea therein shall, of itself, create a presumption that the Indemnitee has not met
such liable legal requirements or, in the case of such a suit brought by the Indemnitee, be a defense to such suit. 

(c)    In any suit brought by the Indemnitee to enforce a right to indemnification or to an Advancement of Expenses
hereunder, or by the Company to recover an Advancement of Expenses, the burden of proving that the Indemnitee is not entitled to be indemnified, or to such Advancement of Expenses, under this Article XI or otherwise shall be on the Company. 

(d)    Without limiting the foregoing, any action commenced pursuant to this Section 11.4 shall be conducted in all
respects as a de novo adjudication on the merits. If a determination shall have been made, or deemed to have been made pursuant to Section 11.2 of this Agreement, that a person is entitled to indemnification, the Company shall be bound thereby.
The Company (or any Member on its behalf) shall be precluded from asserting in any action pursuant to this Section 11.4 that the procedures and presumptions of this Article XI are not valid, binding and enforceable. 

11.5    Non-Exclusivity of Rights. The rights to indemnification and to the
Advancement of Expenses conferred in this Article XI shall not be exclusive of any other right which any person may have or hereafter acquire under applicable law, under any other agreement, pursuant to any vote of Members or otherwise. 

11.6    Insurance. The Board of Managers shall be authorized to cause the Company to maintain insurance, in
reasonable amounts and with responsible carriers, at the Company’s expense, to insure any amounts indemnifiable hereunder as well as to protect itself and any Member or Representative thereof or any employee or agent of the Company or another
enterprise against any expense, liability or loss of the kind referred to in Section 11.1 of this Agreement, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Act. 

  
 48 













 11.7    Contribution by Company. The Company hereby agrees that,
in the event that the indemnification provided for in this Article XI hereof is for any reason finally judicially determined to be unavailable, the Company shall contribute to the payment of any and all expenses, liability and loss (including
attorneys’ fees, judgments, fines, ERISA or other excise taxes or penalties, and amounts paid in settlement) in such proportion as is appropriate to reflect the relative fault of the Company and the Indemnitee with respect to such expenses,
liability and loss. 
 11.8    Limitation of Indemnity. Anything in this Article XI to the contrary
notwithstanding, the Members and or Board Members shall not be entitled to receive or be paid any amount pursuant to this Article XI that would be prohibited by Section 18-108 of the Act. 

ARTICLE XII 
 MISCELLANEOUS 

12.1    Loans to the Company. Any Member (the “Lending Member”) may lend funds to the Company on such
terms as may be deemed reasonable by the Board of Managers; provided, however, that the Board of Managers shall offer each other Member the right to participate in any such loan of funds to the Company upon the same terms as agreed upon with the
Lending Member.

Class A Units shall be required to amend this Agreement. 
 12.3    Benefits of Agreement. Nothing in this
Agreement, expressed or implied, is intended or shall be construed to give to any creditor of the Company, to any creditor of any Member or any person Controlling any Member or to any other person or entity whatsoever, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any covenant, Condition or provisions herein contained, and such provisions are and shall be held to be for the sole and exclusive benefit of the Members, the persons Controlling the Members
(other than creditors of such persons) and the Company, subject to the provisions of Article XI of this Agreement.

required or permitted hereunder shall be in writing, and shall be delivered or sent, as the case may be, by any of the following methods: (a) personal delivery; (b) email; (c) registered or certified mail, postage prepaid, return receipt
requested or (d) nationally recognized courier service. Any notice required or permitted to be delivered to any Member under the provisions of this Agreement shall be deemed delivered upon the actual receipt of written notice by the Member to

 49 













 12.6    Provisions Severable. Every provision of this agreement
is intended to be severable and, if any term or provision hereof is illegal or invalid for any reason whatsoever, such illegality or invalidity shall not affect the validity of the remainder of this Agreement. 

12.7    Counterparts. This Agreement, any amendments hereto, may be executed in counterparts, each of which shall
be deemed an original, and such counterparts shall constitute but one and the same instrument. A signature page hereof that are transmitted by facsimile or portable document (.pdf) format shall have the same effect as delivery of a manually signed
counterpart hereof. An electronic or mechanical signature of this Agreement shall have the same effect as a manual signature. 

12.8    Headings. The headings of the various sections of this Agreement are intended solely for convenience of

12.9    Amendment of Certificate. If this Agreement is amended or there is a change in circumstances that must be
reflected in an amendment to the Certificate pursuant to the terms of the Act, then the Board of Managers shall promptly thereafter cause to be filed with the proper authority an amendment to the Certificate and such other certificates of fictitious

12.10    Applicable Law. This Agreement shall be governed by and construed in accordance with the laws of the State
