Section 2.22    LIBOR Successor. 

(a)     Benchmark Replacement. (i) Notwithstanding anything to the contrary herein or in any
other Loan Document, if a Benchmark Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting
of the then-current Benchmark, then (x) if a Benchmark Replacement is determined in accordance with clause (1) or (2) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement
will replace such Benchmark for all purposes hereunder and under any Loan Document in respect of such Benchmark setting and subsequent Benchmark settings without any amendment to, or further action or consent of any other party to, this Agreement or
any other Loan Document and (y) if a Benchmark Replacement is determined in accordance with clause (3) of the definition of “Benchmark Replacement” for such Benchmark Replacement Date, such Benchmark Replacement will replace such
Benchmark for all purposes hereunder and under any Loan Document in respect of any Benchmark setting at or after 5:00 p.m. (New York City time) on the fifth Business Day after the date notice of such Benchmark Replacement is provided to the Lenders
without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document so long as the Administrative Agent has not received, by such time, written notice of objection to such Benchmark Replacement
from Lenders comprising the Required Lenders. 
 (ii)    Notwithstanding anything to the contrary herein or in any other
Loan Document and subject to the proviso below in this paragraph, if a Term SOFR Transition Event and its related Benchmark Replacement Date have occurred prior to the Reference Time in respect of any setting of the then-current Benchmark, then, to
the extent the Borrower and the Administrative Agent mutually agree, the applicable Benchmark Replacement may replace the then-current Benchmark for all purposes hereunder or under any Loan Document in respect of such Benchmark setting and
subsequent Benchmark settings, without any amendment to, or further action or consent of any other party to, this Agreement or any other Loan Document; provided that, this clause (a)(ii) shall not be effective unless the Administrative Agent
has delivered to the Lenders and the Borrower a Term SOFR Notice. 
 (b)     Benchmark Replacement Conforming
Changes. In connection with the implementation of a Benchmark Replacement, the Administrative Agent will have the right to make Benchmark Replacement Conforming Changes from time to time and, notwithstanding anything to the contrary
herein or in any other Loan Document, any amendments implementing such Benchmark Replacement Conforming Changes will become effective without any further action or consent of any other party to this Agreement or any other Loan Document. 

  
 -3- 

 (c)    Notices; Standards for Decisions and
Determinations. The Administrative Agent will promptly notify the Borrower and the Lenders of (i) any occurrence of a Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in
Election, as applicable, and its related Benchmark Replacement Date, (ii) the implementation of any Benchmark Replacement, (iii) the effectiveness of any Benchmark Replacement Conforming Changes, (iv) the removal or reinstatement of
any tenor of a Benchmark pursuant to clause (d) below and (v) the commencement or conclusion of any Benchmark Unavailability Period. Any determination, decision or election that may be made by the Administrative Agent or, if applicable,
any Lender (or group of Lenders) pursuant to this Section 2.22, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or
date and any decision to take or refrain from taking any action or any selection, will be conclusive and binding absent manifest error and may be made in its or their sole discretion and without consent from any other party to this Agreement or any
other Loan Document, except, in each case, as expressly required pursuant to this Section 2.22. 
 (d)
    Unavailability of Tenor of Benchmark. Notwithstanding anything to the contrary herein or in any other Loan Document, at any time (including in connection with the implementation of a Benchmark Replacement), (i)
if the then-current Benchmark is a term rate (including Term SOFR or LIBO Rate) and either (A) any tenor for such Benchmark is not displayed on a screen or other information service that publishes such rate from time to time as selected by the
Administrative Agent in its reasonable discretion or (B) the regulatory supervisor for the administrator of such Benchmark has provided a public statement or publication of information announcing that any tenor for such Benchmark is or will be
no longer representative, then the Administrative Agent may modify the definition of “Interest Period” for any Benchmark settings at or after such time to remove such unavailable or
non-representative tenor and (ii) if a tenor that was removed pursuant to clause (i) above either (A) is subsequently displayed on a screen or information service for a Benchmark (including a
Benchmark Replacement) or (B) is not, or is no longer, subject to an announcement that it is or will no longer be representative for a Benchmark (including a Benchmark Replacement), then the Administrative Agent may modify the definition of
“Interest Period” for all Benchmark settings at or after such time to reinstate such previously removed tenor. 

(e)    Benchmark Unavailability Period. Upon the Borrower’s receipt of notice of the commencement of a
Benchmark Unavailability Period, the Borrower may revoke any request for a Eurocurrency Borrowing of, conversion to or continuation of Eurocurrency Loans to be made, converted or continued during any Benchmark Unavailability Period and, failing
that, the Borrower will be deemed to have converted any such request into a request for a Borrowing of or conversion to ABR Loans. During any Benchmark Unavailability Period or at any time that a tenor for the then-current Benchmark is not an
Available Tenor, the component of ABR based upon the then-current Benchmark or such tenor for such Benchmark, as applicable, will not be used in any determination of ABR. 

(f)    Certain Defined Terms. As used in this Section 2.22: 

“Available Tenor” means, as of any date of determination and with respect to the then-current Benchmark, as applicable, any
tenor for such Benchmark or payment period for interest calculated with reference to such Benchmark, as applicable, that is or may be used for determining the length of an Interest Period pursuant to this Agreement as of such date and not including,
for the avoidance of doubt, any tenor for such Benchmark that is then-removed from the definition of “Interest Period” pursuant to Section 2.22(d). 

  
 -4- 

 “Benchmark” means, initially, LIBO Rate; provided that if a
Benchmark Transition Event, a Term SOFR Transition Event or an Early Opt-in Election, as applicable, and its related Benchmark Replacement Date have occurred with respect to LIBO Rate or the then-current
Benchmark, then “Benchmark” means the applicable Benchmark Replacement to the extent that such Benchmark Replacement has replaced such prior benchmark rate pursuant to Section 2.22(a). 

“Benchmark Replacement” means, for any Available Tenor, one of the alternatives listed in clauses (1) through (3) below
that has been mutually selected by the Administrative Agent and the Borrower, provided that in the case of clauses (1) and (2), it can be determined by the Administrative Agent for the applicable Benchmark Replacement Date: 

(1)     the sum of: (a) Term SOFR and (b) the related Benchmark Replacement Adjustment; 

(2)     the sum of: (a) Daily Simple SOFR and (b) the related Benchmark Replacement Adjustment; or 

(3)     the sum of: (a) the alternate benchmark rate that has been selected by the Administrative Agent and the
Borrower as the replacement for the then-current Benchmark for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a replacement benchmark rate or the mechanism for determining such a rate by
the Relevant Governmental Body or (ii) any evolving or then-prevailing market convention for determining a benchmark rate as a replacement for the then-current Benchmark for U.S. dollar-denominated syndicated credit facilities at such time and
(b) the related Benchmark Replacement Adjustment; 
 provided that, in the case of clause (1), such Unadjusted Benchmark
Replacement is displayed on a screen or other information service that publishes such rate from time to time as selected by the Administrative Agent in its reasonable discretion; provided, further, that notwithstanding anything to the
contrary in this Agreement or in any other Loan Document, upon the occurrence of a Term SOFR Transition Event, and the delivery of a Term SOFR Notice, on the applicable Benchmark Replacement Date, the “Benchmark Replacement” shall revert
to and shall be deemed to be the sum of (a) Term SOFR and (b) the related Benchmark Replacement Adjustment, as set forth in clause (1) of this definition (subject to the first proviso above). 

If the Benchmark Replacement as determined pursuant to clause (1), (2) or (3) above would be less than the Floor, the Benchmark
Replacement will be deemed to be the Floor for the purposes of this Agreement and the other Loan Documents. 
 “Benchmark Replacement
Adjustment” means, with respect to any replacement of the then-current Benchmark with an Unadjusted Benchmark Replacement for any applicable Interest Period and Available Tenor for any setting of such Unadjusted Benchmark Replacement:

“Benchmark Replacement,” the first alternative set forth in the order below that can be determined by the Administrative Agent: 

(a)     the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive
or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that has been selected or recommended by the Relevant Governmental Body for the replacement of such Benchmark with the applicable
Unadjusted Benchmark Replacement for the applicable Corresponding Tenor; 
 (b)     the spread adjustment (which may be
a positive or negative value or zero) as of the Reference Time such Benchmark Replacement is first set for such Interest Period that would apply to the fallback rate for a derivative transaction referencing the ISDA Definitions to be effective upon
an index cessation event with respect to such Benchmark for the applicable Corresponding Tenor; and 
 (2)     for
purposes of clause (3) of the definition of “Benchmark Replacement,” the spread adjustment, or method for calculating or determining such spread adjustment, (which may be a positive or negative value or zero) that has been selected by
the Administrative Agent and the Borrower for the applicable Corresponding Tenor giving due consideration to (i) any selection or recommendation of a spread adjustment, or method for calculating or determining such spread adjustment, for the
replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement by the Relevant Governmental Body on the applicable Benchmark Replacement Date or (ii) any evolving or then-prevailing market convention for determining a spread
adjustment, or method for calculating or determining such spread adjustment, for the replacement of such Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar-denominated syndicated credit facilities; 

provided that, in the case of clause (1) above, such adjustment is displayed on a screen or other information service that
publishes such Benchmark Replacement Adjustment from time to time as selected by the Administrative Agent in its reasonable discretion. 

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or
operational changes (including changes to the definitions of “Adjusted LIBO Rate,” “ABR,” “Business Day,” “Interest Period” and “LIBO Rate,” the timing and frequency of determining rates and making
payments of interest, timing of borrowing requests or prepayment, conversion or continuation notices, length of lookback periods, the applicability of breakage provisions, and other technical, administrative or operational matters) that the
Administrative Agent decides may be appropriate to reflect the adoption and implementation of such Benchmark Replacement and to permit the administration thereof by the Administrative Agent in a manner substantially consistent with market practice
(or, if the Administrative Agent decides that adoption of any portion of such market practice is not administratively feasible or if the Administrative Agent determines that no market practice for the administration of such Benchmark Replacement
exists, in such other manner of administration as the Administrative Agent decides is reasonably necessary in connection with the administration of this Agreement and the other Loan Documents).

the calculation thereof) permanently or indefinitely ceases to provide all Available Tenors of such Benchmark (or such component thereof); 

(2)    in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public
statement or publication of information referenced therein; 
 (3)    in the case of a Term SOFR Transition Event, the

date notice of such Early Opt-in Election is provided to the Lenders, so long as the Administrative Agent has not received, by 5:00 p.m. (New York City time) on the fifth Business Day after the date notice of
such Early Opt-in Election is provided to the Lenders, written notice of objection to such Early Opt-in Election from Lenders comprising the Required Lenders. 

For the avoidance of doubt, (i) if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than,
the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination and (ii) the “Benchmark Replacement Date” will be deemed to have
occurred in the case of clause (1) or (2) with respect to any Benchmark upon the occurrence of the applicable event or events set forth therein with respect to all then-current Available Tenors of such Benchmark (or the published component used
in the calculation thereof).

(2)     a public statement or publication of information by the regulatory supervisor for the administrator of such

statement or publication, there is no successor administrator that will continue to provide any Available Tenor of such Benchmark (or such component thereof); or 

(3)     a public statement or publication of information by the regulatory supervisor for the administrator of such
Benchmark (or the published component used in the calculation thereof) announcing that all Available Tenors of such Benchmark (or such component thereof) are no longer representative.

MANAGEMENT

 

Section
4.1 Board of Managers.

 

(a)
The Company will be managed by a board of Managers (the “Board”) and the Board initially will be comprised of four
(4) Managers. Atomwise will have the right to designate two (2) Managers (each an “Atomwise Manager”) and StemoniX
will have the right to designate two (2) Managers (each a “StemoniX Manager”). The initial Atomwise Managers are Han
Lim and Izhar Wallach and the initial StemoniX Managers are Ryan Gordon, Ph.D. and Yung-Ping Yeh. Each Manager is entitled to
one (1) vote.

 

(b)
Any Manager shall be deemed to have resigned from the Board (without requiring any further action by the Board or the other Members)
at such time as the Member that appointed such Manager ceases to be a Member, or by giving ten (10) days written notice to the
Board, which prior notice period may be waived by the Board. A Manager may otherwise only be removed and/or replaced by written
notice to the Board at any time by the Member that appointed such Manager.

 

(c)
Subject to Section 3.8, all actions required or permitted to be taken by the Board shall be so taken only with the approval of
a majority of all of the Managers and with at least one Atomwise Manager and at least one StemoniX Manager included in the majority
voting in favor of the action, which approval may be given at a duly-called meeting of the Board or by written consent without
a meeting pursuant to Section 4.1(h). With respect to any matter that is not a Reserved Matter, in the event of a deadlock, the
Atomwise Managers and the StemoniX Managers shall meet in person or telephonically and discuss in good faith to try to resolve
any such deadlock matter within thirty (30) days. If the deadlock is unresolved within such thirty (30) days, then such claim,
controversy or dispute will be resolved in accordance with Section 10.1.

 

(d)
The Board shall memorialize their actions in a manner that is appropriate under the circumstances, and to the extent that such
actions are memorialized in written form (including as minutes), such documents shall be incorporated into the books and records
of the Company, which books and records shall be maintained in duplicate at the offices of each of the Members. Without limiting
the foregoing, all matters submitted for the approval of the Board shall be notified to all Managers in accordance with Section
4.1(f).

 

    	10

     

    

  

(e)
Managers may participate in any regularly scheduled or special meetings of the Board telephonically or through other similar communications
equipment, as long as all of the representatives participating in the meeting can hear one another. Participation in a meeting
pursuant to the preceding sentence shall constitute presence in person at such meeting for all purposes of this LLC Agreement.
Regular meetings of the Board shall be held at least once every six (6) months.

 

(f)
Notice of any meeting of, or of any action to be taken by written consent without a meeting pursuant to Section 4.1(h) by, the
Board shall be given as far in advance of the meeting or such proposed action as is reasonably practicable and may be given by
email, certified mail (return receipt requested) or personal delivery. Managers shall give notice of any meeting at least two
(2) Business Days prior to such meeting, unless otherwise agreed by the Managers. A Manager may waive notice of the date, time,
place and purpose or purposes of a meeting of the Board. A waiver of notice is effective whether given before, at or after a meeting,
and whether given in writing, orally or by attendance. Attendance by a Manager at a meeting is a waiver of notice of that meeting,
unless the Manager objects at the beginning of the meeting to the transaction of business because the meeting is not properly
called or convened, or objects before a vote on an item of business because the item may not properly be considered at that meeting
and does not participate in the consideration of the item at that meeting.

 

(g)
A quorum shall be required to conduct any business at any meeting of the Board, and shall be deemed present at any such meeting
so long as Managers entitled to cast at least a majority of the total number of votes entitled to be cast by the full Board are
in attendance and at least one (1) Atomwise Manager and one (1) StemoniX Manager are in attendance. Each party shall use commercially
reasonable efforts to cause its designated Managers to attend (in person or by other means permitted under this LLC Agreement)
each duly called meeting of the Board.

 

(h)
Any action required or permitted to be taken at a meeting of the Board may be taken without a meeting by the written consent of
the requisite number of Managers required to approve the applicable matter, which consent shall set forth the actions to be so
taken; provided that the Company shall endeavor to provide at least two (2) Business Days’ advance written notice of the
proposed action and the purpose therefor to all Managers, to the extent reasonably practicable given any relevant exigencies of
time. Any such written consent shall have the same effect as an act of a vote of the requisite number of Managers required to
approve the applicable matter, as appropriate, at a properly called and constituted meeting of the Board. Copies of any executed
written consent shall be delivered to all Managers promptly after execution thereof; provided, that, failure to do so shall not
affect the validity of the action taken.

 

(0
Notwithstanding anything in this LLC Agreement to the contrary, no Manager shall vote or otherwise act by proxy unless approved
by the Board on a case-by-case basis.

 

Section
4.2 Management. Except as otherwise provided in the Act or this LLC Agreement, all authority, power and discretion to manage
and control the business, Property and affairs of the Company, to make all decisions regarding those matters and to perform any
and all other acts or activities customary or incident to the management of the Company’s business, Property and affairs
shall be vested in the Board. The Parties anticipate that one of the first orders of business for the Board will be to establish
an operating structure and a process for setting budgets and determining contributions of cash.

4.4 Waiver of Fiduciary Duties; Performance of Duties. As set forth in ARTICLE 9, no Manager shall owe any fiduciary duties
to the Company or any of its subsidiaries, the Members or any other Person who is a party to or is otherwise bound by this LLC
Agreement. Subject to ARTICLE 9, whenever in this LLC Agreement or any other agreement any Manager is permitted or required to
make a decision, provide a consent or take an action in its own discretion, judgment or other determination, such Manager shall,
to the fullest extent permitted by law, be entitled to make such decision, provide consent or take or not take such action in
its sole and absolute discretion (regardless of whether there is a reference to “sole discretion” or “discretion”),
and shall be entitled to consider only such interests and factors as it desires, including its own interests, shall have no duty
or obligation (fiduciary or otherwise) to give any consideration to any interest of or factors affecting the Company or any of
its subsidiaries or the Members and shall not be subject to any other or different standards imposed by this LLC Agreement or
any other agreement contemplated hereby, under the Act or under any other law, rule or regulation or in equity. In performing
his or her duties as a Manager, each Manager is entitled to rely on information, opinions, reports or statements, including financial
statements and other financial data, prepared or presented by (a) officers, employees or agents of the Company whom the Manager
believes to be reliable and competent in the matters presented, and (b) legal counsel, independent accountants or other Persons
as to matters which the Manager believes to be within such Person’s professional or expert competence; so long as, in any
such case, the Manager acts in good faith, after reasonable inquiry when a need is indicated by the circumstances and without
knowledge that would cause such reliance to be unwarranted.

 

Section
4.5 Officers. Subject in each case to the terms and conditions of this LLC Agreement (including the approval rights of the
Board) the Board may appoint at any time, one or more individuals to manage the day-to-day business affairs of the Company (each,
an “Officer”), may assign titles to such Officers as the Board may deem necessary or advisable, and may delegate to
such Officers such powers, authority and responsibilities as the Board may determine. Each Officer shall serve at the pleasure
of the Board, and any appointment or delegation pursuant to this Section 4.5 may be modified and/or revoked by the Board at any
time (with or without giving notice) and for any reason or no reason.

a distribution of Property in kind, subject to the amounts and priorities set forth in Section 8.2(b), the liquidating trustee

required by any non-waivable provision of the Act or other applicable law: (a) no Member in its capacity as such shall be liable
in any manner whatsoever for any debt, liability or other obligation of the Company, whether such debt, liability or other obligation

competence, including information, opinions, reports or statements as to the value and amount of the assets, liabilities, profits
or losses of the Company, the value and amount of assets or reserves or contracts, agreements or other undertakings that would
be sufficient to pay claims and obligations of the Company or to make reasonable provision to pay such claims and obligations
or any other facts pertinent to the existence and amount of assets from which distributions to Members or creditors might properly
be paid.

Section
9.3 Indemnification.

 

(a)
Subject to Section 9.1, the Company shall, to the fullest extent permitted under the Act, indemnify, defend and hold harmless
each Covered Person against any losses, claims, damages, liabilities, costs, expenses (including all reasonable fees and expenses
of counsel selected by the indemnified party), judgments, fines, penalties, settlements and other amounts (“Damages”)
arising from any and all claims, demands, actions, suits, proceedings or investigations (“Proceedings”), in which
such Covered Person may be involved or become subject to, in connection with any matter arising out of or in connection with or
related to the Company’s business or affairs, a Covered Person’s services (whether as an employee, agent, officer,
corporate director, member, manager, shareholder, partner or in any other capacity) to the Company or any Person owned or Controlled
by the Company or as to which such Covered Person has provided services on behalf of any of the foregoing, any other Company assets,
this LLC Agreement or any related document (including the Collaboration Agreement) unless, in each case, a court of competent
jurisdiction determines in a final, nonappealable judgment that (i) such Damages are a result of such Covered Person breaching
a covenant or other express obligation set forth in this LLC Agreement or a representation, warranty, covenant or other express
obligation set forth in any other agreement with the Company to which such Covered Person is a party including, as applicable,
the Collaboration Agreement, (ii) in the case of all Covered Persons other than any Officer, an act or omission of such Covered
Person constituted Malfeasance, a material breach of any agreement (other than this LLC Agreement) between such Covered Person
and the Company or any of the Company’s subsidiaries, subject to any notice and cure rights expressly set forth in such
agreement or a bad faith violation of the implied contractual covenant of good faith and fair dealing, or (iii) in the case of
any Officer, (x) such Officer did not act in good faith and in a manner he or she believed to be in, or not contrary to, the best
interests of the Company, or (y) the conduct of such Officer constituted Malfeasance or a material breach of any agreement (other
than this LLC Agreement) between such Covered Person and the Company or any of the Company’s subsidiaries, subject to any
notice and cure rights expressly set forth in such agreement. Each Covered Person shall have the right to employ separate counsel
selected by such Covered Person in connection with any such Proceedings. If any Covered Person becomes involved in or subject
to any such Proceedings, the Company shall reimburse such Covered Person for its reasonable legal and other reasonable out-of-pocket
expenses (including the cost of any investigation and preparation) as they are incurred in connection therewith; provided that
such Covered Person shall promptly repay to the Company the amount of any such reimbursed expenses paid to it if it shall be finally
judicially determined that such Covered Person was not entitled to be indemnified by the Company in connection with such Proceedings.
If for any reason (other than as expressly contemplated in the first sentence of this Section 9.3(a)) the foregoing indemnification
is unavailable to such Covered Person, or insufficient to hold it harmless, then the Company shall pay to the Covered Person the
full amount paid or payable by such Covered Person as a result of such Damages. If the Company is required to make an indemnification
payment to a Covered Person pursuant to this Section 9.3(a) such payment shall be increased to take into account any tax imposed
on such Covered Person with respect to such payment such that the Covered Person shall be in the same position it would have been
in had no tax been imposed on such indemnification payment. The obligations of the Company under this Section 9.3(a) shall be
satisfied solely out of and to the extent of the Company assets or any insurance policy maintained by the Company and no Covered
Person shall have any personal liability on account thereof.

 

(b)
Certain of the Covered Persons may have certain rights to indemnification, advancement of expenses and/or insurance provided
by Members or their Affiliates (collectively, the “Secondary Indemnitors”). Notwithstanding anything to the contrary
in this ARTICLE 9, the Members hereby agree that (a) as among the Secondary Indemnitors and the Company, the Company (including
its insurance carriers, to the extent of any insurance policies maintained by the Company) is the indemnitor of first resort (i.e.,
its obligations to the Covered Persons are primary and any obligation of the Secondary Indemnitors to advance expenses or to provide
indemnification for the same expenses or liabilities incurred by the Covered Persons are secondary), (b) the Company shall be
liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement by or on behalf of any
such Covered Persons to the extent required by this LLC Agreement (or any agreement between the Company and such Covered Persons),

and releases the Secondary Indemnitors from any and all claims against the Secondary Indemnitors for contribution, subrogation

Indemnitors on behalf of any Covered Person with respect to any claim for which such Covered Person has sought indemnification
from the Company shall affect the foregoing and the Secondary Indemnitors shall have a right of contribution and/or be subrogated
to the extent of such advancement or payment to all of the rights of recovery of such Covered Person against the Company.

(c)

had an interest in the transaction with respect to which the indemnification applies; provided, the transaction was otherwise
permitted by the terms of this LLC Agreement.

 

Section
9.4 Survival of Rights. Notwithstanding any other provision of this LLC Agreement, any repeal or modification (including by
operation of law) of the provisions of this ARTICLE 9 shall not adversely affect any right or protection hereunder of any Covered
Person in respect of any act or omission occurring prior to the time of such repeal or modification, the Covered Persons shall
be third party beneficiaries of this LLC Agreement for purposes of this ARTICLE 9; provided the provisions of this Section 9.4
are for the benefit of the Covered Persons and shall not be deemed to create any rights for the benefit of any other Person.

Section
10.1 Dispute Resolution.

 

(a)
The parties hereto shall negotiate in good faith and use reasonable efforts to settle any dispute, controversy or claim arising
from or related to this LLC Agreement or the breach thereof. If the parties do not fully settle, and a party wishes to pursue
the matter, each such dispute, controversy or claim that is not an Excluded Claim shall be finally resolved by binding arbitration
administered by the American Arbitration Association (“AAA”) pursuant to Commercial Arbitration Rules of the
AAA then in effect, and judgment on the arbitration award may be entered in any court having jurisdiction thereof. The arbitration
shall be conducted by single arbitrator experienced in small molecule drug development. If the parties are unable to agree on
such arbitrator within thirty (30) days after initiation of arbitration, the arbitrator shall be appointed by AAA. The place of
arbitration shall be Denver, Colorado and all proceedings and communications shall be in English.

 

(b)
Any party may apply to the arbitrator for interim injunctive relief until the arbitration award is rendered or the controversy
is otherwise resolved. Any party also may, without waiving any remedy under this LLC Agreement, seek from any court having jurisdiction
any injunctive or provisional relief necessary to protect the rights or property of that party pending the arbitration award.
The arbitrator shall have no authority to award punitive or any other type of damages not measured by a party’s compensatory
damages. Each party shall bear its own costs and expenses and attorneys’ fees. Each party shall initially bear equal shares
of the arbitrator’s fees and any administrative fees of arbitration, and upon the conclusion of the arbitration proceeding,
the party (or parties) against which the decision is rendered shall reimburse the other parties (or party) for its or their share
of the arbitrator’s fees and any administrative fees of arbitration (but not the attorneys’ fees or other costs and
expenses).

 

    	20

     

    

 

(c)
Except to the extent necessary to confirm an award or as may be required by law, neither a party nor an arbitrator may disclose
the existence, content, or results of an arbitration without the prior written consent of all parties. In no event shall an arbitration
be initiated after the date when commencement of a legal or equitable proceeding based on the dispute, controversy or claim would
be barred by the applicable Delaware statute of limitations.

 

(d)
With respect to each Excluded Claim arising out of, relating to or based upon this LLC Agreement, each party hereto hereby irrevocably
and unconditionally submits, for itself and its Property, to the exclusive jurisdiction of the Court of Chancery of the State
of Delaware (or, if the Court of Chancery of the State of Delaware declines to accept jurisdiction over a particular Excluded
Claim, any federal court within the State of Delaware, or, if no federal court in the State of Delaware accepts jurisdiction,
any state court within the State of Delaware), and each of the parties hereto irrevocably and unconditionally agrees that all
Excluded Claims may be heard and determined in such courts. Each of the parties hereto agrees that a final judgment in any such
action of proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Each party hereby waives any right it may have to assert the doctrine of forum non conveniens or similar
doctrine or to object to venue with respect to any proceeding brought in accordance with this Section 10.1(d), and stipulates
that the courts stated above in this Section 10.1(d) shall have in personam jurisdiction and venue over each of the parties
for the purpose of litigating any Excluded Claim arising out of or relating in any way whatsoever to this LLC Agreement. Each
party hereby authorizes and agrees to accept service of process sufficient for personal jurisdiction in any Excluded Claim against
it as contemplated by this Section 10.01(d) by the giving of notices as set forth in Section 10.2 of this LLC Agreement.

 

Section
10.2 Notices. Except as otherwise expressly provided in this LLC Agreement, all notices, requests and other communications
to any party hereunder shall be in writing (including e-mail) and if to the Company, shall be to the address set forth in Section
2.6, and if to the Members, shall be to the addresses set forth for such Members in Exhibit B, or as such party shall hereafter
specify for the purpose by notice to the other parties in a manner as provided under this Section 10.2. Each such notice, request
or other communication shall be effective (a) if given by e mail, at the time such e mail is transmitted and e mail confirmation
is received (or, if such time is not on a Business Day or is on a Business Day but after 5 p.m. in the location of the primary
office of the recipient, at the beginning of the next such Business Day), (b) if given by mail, three (3) Business Days (or, if
to an address outside the United States, seven (7) calendar days) after such communication is deposited in the mail with first-class
postage prepaid, addressed as aforesaid, or (c) if given by any other means, when delivered at the address specified pursuant
to this Section 10.2.

 

Section
10.3 No Third Party Beneficiaries. This LLC Agreement is not intended to confer any rights or remedies hereunder upon, and
shall not be enforceable by, any Person other than (i) the Members and the Company, (ii) with respect to the provisions of ARTICLE
9, each Covered Person, or (iii) any other Person expressly designated as a third party beneficiary in this LLC Agreement.

 

Section

The Company shall maintain a separate Capital Account for each Member in accordance with the principles and requirements set forth
in Section 1.704-1(b)(2)(iv) of the Treasury Regulations.

 

(b)
For purposes of computing the amount of any item of Company income, gain, loss or deduction to be allocated pursuant to ARTICLE
5 of the LLC Agreement and to be reflected in the Capital Accounts, the determination, recognition and classification of any such
item shall be the same as its determination, recognition and classification for federal income tax purposes (including any method
of depreciation, cost recovery or amortization used for this purpose); provided that: (i) the computation of all items of income,
gain, loss and deduction shall include those items described in Code Section 705(a)(1)(B) or Code Section 705(a)(2)(B) and Treasury
Regulations Section 1.704-1(b)(2)(iv)(i), without regard to the fact that such items are not includable in gross income or are
not deductible for federal income tax purposes; (ii) if the Book Value of any Company Property is adjusted pursuant to Treasury
Regulations Section 1.704-1(b)(2)(iv)(e) or (f), the amount of such adjustment shall be taken into account as gain or loss from
the disposition of such Property; (iii) items of income, gain, loss or deduction attributable to the disposition of Company Property
having a Book Value that differs from its adjusted basis for tax purposes shall be computed by reference to the Book Value of
such Property; (iv) items of depreciation, amortization and other cost recovery deductions with respect to Company Property having
a Book Value that differs from its adjusted basis for tax purposes shall be computed by reference to the Property’s Book
Value in accordance with Treasury Regulations Section 1.704-1(b)(2)(iv)(g); and (v) to the extent an adjustment to the adjusted
tax basis of any Company asset pursuant to Code Sections 732(d), 734(b) or 743(b) is required, pursuant to Treasury Regulations
Section 1.704-1(b)(2)(iv)(m), to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital
Accounts shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases
such basis).

 

SECTION

ALLOCATIONS

 

3.1
Allocations. Except as otherwise provided in Section 3.2 of this Tax Appendix, Profits and Losses (and, if necessary, items
of income, gain, loss, and deduction) for any Taxable Year shall be allocated among the Members in such a manner that, as of the
end of such Taxable Year, the sum of (i) the Capital Account of each Member, (ii) such Member’s share of Minimum Gain (as
determined according to Treasury Regulations Section 1.704-2(g)) and (iii) such Member’s partner nonrecourse debt minimum
gain (as defined in Treasury Regulations Section 1.704-2(i)(3)) shall be equal to the respective net amounts, positive or negative,
which would be distributed to them or for which they would be liable to the Company under the Act, determined as if the Company
were to (i) liquidate the assets of the Company for an amount equal to their Book Value and (ii) distribute the proceeds of liquidation
pursuant to Section 8.2(b) of the LLC Agreement.

 

    	3

     

    

  

3.2
Special Allocations. The provisions of the Treasury Regulations promulgated under Code Section 704(b) relating to the qualified
income offset, minimum gain chargeback, minimum gain chargeback with respect to member nonrecourse debt (as defined in Treasury
Regulations Section 1.704-2(b)(4)), the allocation of member nonrecourse deductions (as defined in Treasury Regulations Section
1.704-2(i)), the allocation of items of deduction, loss or expenditure relating to member nonrecourse debt and the limitation
on the allocation of Losses relating to a Member’s Adjusted Capital Account Deficit are hereby incorporated by reference
and shall be applied to the allocation of Company items of income, gain, loss or deduction in the manner provided in such Treasury
Regulations. However, the Members do not intend that the “deficit restoration obligation” described in Section 1.704-1(b)(2)(ii)(c)
of the Treasury Regulations be incorporated into this LLC Agreement. To the extent an amount of income, gain, loss or deduction
has been allocated pursuant to this Section 3.2, the Company shall make offsetting allocations in an amount and manner determined
appropriate by the Board so as to cause the net amount of all such allocations to be the same (to the maximum extent possible)
as the allocations that would have occurred in the event that no allocations had been made pursuant to the foregoing provisions
of this Section 3.2.

 

3.3
Tax Allocations.

 

(a)
The income, gains, losses, deductions and credits of the Company will be allocated, for federal, state and local income tax purposes,
among the Members in accordance with the allocation of such income, gains, losses, deductions and credits among the Members for
computing their Capital Accounts.

 

(b)
In accordance with Code Section 704(c) and the Treasury Regulations thereunder, income, gain, loss and deduction with respect
to any Property contributed to the capital of the Company or owned by the Company upon the occurrence of any of the events described
in Treasury Regulations Section 1.704-1(b)(2)(iv)(f)(5) shall, solely for tax purposes, be allocated among the Members so as to
take into account any variation between the adjusted basis of such Property to the Company for federal income tax purposes and
its Book Value using any reasonable method (within the meaning of Treasury Regulations Section 1.704-3) as determined by the Board.

 

SECTION

OTHER
TAX MATTERS

obligations under applicable law.
