NEW YORK CITY TIME, FIVE YEARS FROM THE CLOSING DATE OF THE COMPANY’S INITIAL 

BUSINESS COMBINATION) 
 VINCERA
PHARMA, INC. 
 CUSIP __________ 

WARRANT 
 THIS WARRANT CERTIFIES THAT, for value
received                 , or registered agents, is the registered holder of a Warrant or Warrants (the “Warrant”), expiring on a date which is five
(5) years from the completion of the Company’s initial business combination, to purchase one-half of one fully paid and non-assessable share (the “Warrant
Shares”), of common stock, $0.0001 par value per share (the “Common Stock”), of VINCERA PHARMA, INC., a Delaware corporation (the “Company”), for each Warrant evidenced by this Warrant Certificate. This Warrant Certificate
is subject to and shall be interpreted under the terms and conditions of the Warrant Agreement (as defined below). 
 The Warrant entitles
the holder thereof to purchase from the Company, from time to time, in whole or in part, commencing on the later to occur of (i) the completion of the Company’s initial business combination or (ii) twelve (12) months following the
closing of the Company’s initial public offering, such number of Warrant Shares at the price of $11.50 per share (the “Warrant Price”), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or
agency of Continental Stock Transfer & Trust Company (the “Warrant Agent”), such payment to be made subject to the conditions set forth herein and in the Warrant Agreement, dated March 5, 2020, between the Company and the
Warrant Agent (the “Warrant Agreement”). In no event shall the registered holder(s) of this Warrant be entitled to receive a net-cash settlement in lieu of physical settlement in Warrant Shares of
the Company. The Warrant Agreement provides that, upon the occurrence of certain events, the Warrant Price and the number of Warrant Shares purchasable hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions. The term
Warrant Price as used in this Warrant Certificate refers to the price per full Warrant Share at which Warrant Shares may be purchased at the time the Warrant is exercised. 

This Warrant will expire on the date first referenced above if it is not exercised prior to such date by the registered holder pursuant to the
terms of the Warrant Agreement or if it is not redeemed by the Company prior to such date. 
 No fraction of a Share will be issued upon any
exercise of a Warrant. If, upon exercise of a Warrant, a holder would be entitled to receive a fractional interest in a Share, the Company will, upon exercise, issue or cause to be issued only the largest whole number of Warrant Shares issuable on
such exercise (and such fraction of a Share will be disregarded). 
 Upon any exercise of the Warrant for less than the total number of full
Warrant Shares provided for herein, there shall be issued to the registered holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Warrant Shares for which the Warrant has not been exercised. 

Warrant Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by
attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor
and evidencing in the aggregate a like number of Warrants. 

 Upon due presentment for registration of transfer of the Warrant Certificate at the office or agency of the
Warrant Agent, a new Warrant Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the limitations
provided in the Warrant Agreement, without charge except for any applicable tax or other governmental charge. 
 The Company and the Warrant
Agent may deem and treat the registered holder(s) as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof, of any distribution to
the registered holder(s), and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. 

This Warrant does not entitle the registered holder(s) to any of the rights of a stockholder of the Company. 

After the Warrant becomes exercisable and prior to its expiration date, the Company reserves the right to call the Warrant at any time, with a
notice of call in writing to the holder(s) of record of the Warrant, giving thirty (30) days’ written notice of such call if the last reported sale price of the Common Stock has been equal to or greater than $16.50 per share for any twenty
(20) trading days within a thirty (30) trading day period ending on the third (3rd) trading day prior to the date on which notice of such call is given, provided that (i) a registration statement under the Securities Act of 1933, as
amended (the “Act”) with respect to the shares of Common Stock issuable upon exercise must be effective and a current prospectus must be available for use by the registered holders hereof or (ii) the Warrants may be exercised on
cashless basis as set forth in the Warrant Agreement and such cashless exercise is exempt from registration under the Act. The call price is $0.01 per Warrant Share. No fractional shares will be issued upon exercise of the Warrant. 

If the foregoing conditions are satisfied and the Company calls the Warrant for redemption, each holder will then be entitled to exercise his,
her or its Warrant prior to the date scheduled for redemption; provided that the Company may require the Registered Holder who desires to exercise the Warrant, to elect cashless exercise as set forth in the Warrant Agreement, and such Registered
Holder must exercise the Warrants on a cashless basis if the Company so requires. Any Warrant either not exercised or tendered back to the Company by the end of the date specified in the notice of call shall be canceled on the books of the Company
and have no further value except for the $0.01 call price.

 2. REGISTRATION RIGHTS. 

2.1 Demand Registration. 

2.1.1 Request for Registration. At any time and from time to time on or after the Closing, the holders of a majority-in-interest of the aggregate of the Closing Payment Shares, Earnout Shares (if any), Initial Shares and shares underlying the Private Warrants may make a written
demand for registration under the Securities Act of all or part of their Registrable Securities (a “Demand Registration”). Any demand for a Demand Registration shall specify the number of shares of Registrable Securities
proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all holders of Registrable Securities of the demand, and each holder of Registrable Securities who wishes to include all or a portion of such
holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such registration, a “Demanding Holder”) shall so notify the Company within fifteen
(15) days after the receipt by the holder of the notice from the Company. Upon any such request, the Demanding Holders shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section 2.1.4 and
the provisos set forth in Section 3.1.1. The Company shall not be obligated to effect more than three (3) Demand Registrations under this Section 2.1.1 in respect of all Registrable Securities. 

2.1.2 Effective Registration. A registration will not count as a Demand Registration until the Registration Statement filed with the
Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has
been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the Registration Statement with respect
to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering; provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration
Statement that has been filed is counted as a Demand Registration or is terminated. 
 2.1.3 Underwritten Offering. If a majority-in-interest of the Demanding Holders so elect and such holders so advise the Company as part of their written demand for a Demand Registration, the offering of such
Registrable Securities pursuant to such Demand Registration shall be in the form of an underwritten offering. In such event, the right of any holder to include its Registrable Securities in such registration shall be conditioned upon such
holder’s participation in such underwriting and the inclusion of such holder’s Registrable Securities in the underwriting to the extent provided herein. All Demanding Holders proposing 

  
 3 

 
to distribute their Registrable Securities through such underwriting shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such
underwriting by a majority-in-interest of the holders initiating the Demand Registration. 

2.1.4 Reduction of Offering. If the managing Underwriter or Underwriters for a Demand Registration that is to be an underwritten
offering advises the Company and the Demanding Holders in writing that the dollar amount or number of shares of Registrable Securities which the Demanding Holders desire to sell, taken together with all other shares of Common Stock or other
securities which the Company desires to sell and the shares of Common Stock, if any, as to which registration has been requested pursuant to written contractual piggy-back registration rights held by other stockholders of the Company who desire to
sell, exceeds the maximum dollar amount or maximum number of shares that can be sold in such offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such
maximum dollar amount or maximum number of shares, as applicable, the “Maximum Number of Shares”), then the Company shall include in such registration: (i) first, the Registrable Securities as to which Demand
Registration has been requested by the Demanding Holders (pro rata in accordance with the number of shares that each such Person has requested be included in such registration, regardless of the number of shares held by each such Person (such
proportion is referred to herein as “Pro Rata”)) that can be sold without exceeding the Maximum Number of Shares; (ii) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing
clause (i), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; and (iii) third, to the extent that the Maximum Number of Shares has not been reached
under the foregoing clauses (i) and (ii), the shares of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons and that can be
sold without exceeding the Maximum Number of Shares. 
 2.1.5 Withdrawal. If a majority-in-interest of the Demanding Holders disapprove of the terms of any underwriting or are not entitled to include all of their Registrable Securities in any offering, such majority-in-interest of the Demanding Holders may elect to withdraw from such offering by giving written notice to the Company and the Underwriter or Underwriters of their
request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the
majority-in-interest of the Demanding Holders withdraws from a proposed offering relating to a Demand Registration, then such registration shall not count as a Demand
Registration provided for in Section 2.1. 
 2.2 Piggy-Back Registration. 

2.2.1 Piggy-Back Rights. If at any time on or after the Closing, the Company proposes to file a Registration Statement under the
Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for
their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.1), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan,
(ii) for an exchange offer or 

  
 4 

 
offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend
reinvestment plan, then the Company shall (x) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which
notice shall describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, of the offering, and (y) offer to the
holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a
“Piggy-Back Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed underwritten
offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities
in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an
underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration. 
 2.2.2
Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number
of shares of Common Stock which the Company desires to sell, taken together with the shares of Common Stock, if any, as to which registration has been demanded pursuant to written contractual arrangements with persons other than the holders of
Registrable Securities hereunder, the Registrable Securities as to which registration has been requested under this Section 2.2, and the shares of Common Stock, if any, as to which registration has been requested pursuant to the written
contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Shares, then the Company shall include in any such registration: 

(a) If the registration is undertaken for the Company’s account: (A) first, the shares of Common Stock or other
securities that the Company desires to sell that can be sold without exceeding the Maximum Number of Shares; (B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common
Stock or other securities, if any, comprised of Registrable Securities, as to which registration has been requested pursuant to the applicable written contractual piggy-back registration rights of such security holders, Pro Rata, that can be sold
without exceeding the Maximum Number of Shares; and (C) third, to the extent that the Maximum Number of shares has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other securities for the account of
other persons that the Company is obligated to register pursuant to written contractual piggy-back registration rights with such persons and that can be sold without exceeding the Maximum Number of Shares; 

  
 5 

 (b) If the registration is a “demand” registration undertaken at
the demand of persons other than either the holders of Registrable Securities, (A) first, the shares of Common Stock or other securities for the account of the demanding persons that can be sold without exceeding the Maximum Number of Shares;
(B) second, to the extent that the Maximum Number of Shares has not been reached under the foregoing clause (A), the shares of Common Stock or other securities that the Company desires to sell that can be sold without exceeding the Maximum
Number of Shares; (C) third, to the extent that the Maximum Number of Shares has not been reached under the foregoing clauses (A) and (B), collectively the shares of Common Stock or other securities comprised of Registrable Securities, Pro
Rata, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Shares; and (D) fourth, to the extent that the Maximum Number of Shares has not been reached under the
foregoing clauses (A), (B) and (C), the shares of Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without
exceeding the Maximum Number of Shares. 
 2.2.3 Withdrawal. Any holder of Registrable Securities may elect to withdraw such
holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement. The Company (whether on its
own determination or as the result of a withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement at any time prior to the effectiveness of such Registration Statement. Notwithstanding
any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 3.3. 

2.2.4 Registrations on Form S-3. The holders of Registrable Securities may at any time and from
time to time after the date that is twelve (12) months from the date the Company files a Current Report on Form 8-K following the Closing containing information required in a Form 10 registration
statement, request in writing that the Company register the resale of any or all of such Registrable Securities on Form S-3 or any similar short-form registration which may be available at such time
(“Form S-3”); provided, however, that the Company shall not be obligated to effect such request through an underwritten offering. Upon receipt of such written request, the Company will
promptly give written notice of the proposed registration to all other holders of Registrable Securities, and, as soon as practicable thereafter, effect the registration of all or such portion of such holder’s or holders’ Registrable
Securities as are specified in such request, together with all or such portion of the Registrable Securities or other securities of the Company, if any, of any other holder or holders joining in such request as are specified in a written request
given within fifteen (15) days after receipt of such written notice from the Company; provided, however, that the Company shall not be obligated to effect any such registration pursuant to this Section 2.2.4: (i) if Form S-3 is not available for such offering; or (ii) if the holders of the Registrable Securities, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose
to sell Registrable 

  
 6 

 
Securities and such other securities (if any) at any aggregate price to the public of less than $500,000. Registrations effected pursuant to this Section 2.2.4 shall not be counted as Demand
Registrations effected pursuant to Section 2.1. 
 3. REGISTRATION PROCEDURES. 

3.1 Filings; Information. Whenever the Company is required to effect the registration of any Registrable Securities pursuant to
Section 2, the Company shall use its best efforts to effect the registration and sale of such Registrable Securities in accordance with the intended method(s) of distribution thereof as expeditiously as practicable, and in connection with any
such request: 
 3.1.1 Filing Registration Statement. The Company shall use its best efforts to, as expeditiously as possible after
receipt of a request for a Demand Registration pursuant to Section 2.1, prepare and file with the Commission a Registration Statement on any form for which the Company then qualifies or which counsel for the Company shall deem appropriate and
which form shall be available for the sale of all Registrable Securities to be registered thereunder in accordance with the intended method(s) of distribution thereof, and shall use its best efforts to cause such Registration Statement to become
effective and use its best efforts to keep it effective for the period required by Section 3.1.3; provided, however, that the Company shall have the right to defer any Demand Registration for up to thirty (30) days, and any Piggy-Back
Registration for such period as may be applicable to deferment of any demand registration to which such Piggy-Back Registration relates, in each case if the Company shall furnish to the holders a certificate signed by the President or Chairman of
the Company stating that, in the good faith judgment of the Board, it would be materially detrimental to the Company and its stockholders for such Registration Statement to be effected at such time; provided further, however, that the Company shall
not have the right to exercise the right set forth in the immediately preceding proviso more than once in any 365-day period in respect of a Demand Registration hereunder. 

3.1.2 Copies. The Company shall, prior to filing a Registration Statement or prospectus, or any amendment or supplement thereto,
furnish without charge to the holders of Registrable Securities included in such registration, and such holders’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration
Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the prospectus included in such Registration Statement (including each preliminary prospectus), and such other documents as the holders of
Registrable Securities included in such registration or legal counsel for any such holders may request in order to facilitate the disposition of the Registrable Securities owned by such holders. 

3.1.3 Amendments and Supplements. The Company shall prepare and file with the Commission such amendments, including post-effective
amendments, and supplements to such Registration Statement and the prospectus used in connection therewith as may be necessary to keep such Registration Statement effective and in compliance with the provisions of the Securities Act until all
Registrable Securities and other securities covered by such Registration Statement have been disposed of in accordance with the intended method(s) of distribution set forth in such Registration Statement or such securities have been withdrawn. 

  
 7 

 3.1.4 Notification. After the filing of a Registration Statement, the Company shall
promptly, and in no event more than two (2) business days after such filing, notify the holders of Registrable Securities included in such Registration Statement of such filing, and shall further notify such holders promptly and confirm such
advice in writing in all events within two (2) business days of the occurrence of any of the following: (i) when such Registration Statement becomes effective; (ii) when any post-effective amendment to such Registration Statement
becomes effective; (iii) the issuance or threatened issuance by the Commission of any stop order (and the Company shall take all actions required to prevent the entry of such stop order or to remove it if entered); and (iv) any request by
the Commission for any amendment or supplement to such Registration Statement or any prospectus relating thereto or for additional information or of the occurrence of an event requiring the preparation of a supplement or amendment to such prospectus
so that, as thereafter delivered to the purchasers of the securities covered by such Registration Statement, such prospectus will not contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading, and promptly make available to the holders of Registrable Securities included in such Registration Statement any such supplement or amendment; except that before filing with the Commission a
Registration Statement or prospectus or any amendment or supplement thereto, including documents incorporated by reference, the Company shall furnish to the holders of Registrable Securities included in such Registration Statement and to the legal
counsel for any such holders, copies of all such documents proposed to be filed sufficiently in advance of filing to provide such holders and legal counsel with a reasonable opportunity to review such documents and comment thereon, and the Company
shall not file any Registration Statement or prospectus or amendment or supplement thereto, including documents incorporated by reference, to which such holders or their legal counsel shall object. 

3.1.5 State Securities Laws Compliance. The Company shall use its best efforts to (i) register or qualify the Registrable
Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the holders of Registrable Securities included in such Registration Statement (in light of their
intended plan of distribution) may request and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be
necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the holders of Registrable Securities included in such Registration Statement to consummate the
disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this
paragraph or subject itself to taxation in any such jurisdiction. 
 3.1.6 Agreements for Disposition. The Company shall enter into
customary agreements (including, if applicable, an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of such Registrable Securities. The
representations, warranties and covenants of the Company in any underwriting agreement which are made to or for the benefit of any Underwriters, to the extent applicable, shall also be made to and for the benefit of the holders of Registrable
Securities included in such registration statement. No holder of Registrable 

  
 8 

 
Securities included in such registration statement shall be required to make any representations or warranties in the underwriting agreement except, if applicable, with respect to such
holder’s organization, good standing, authority, title to Registrable Securities, lack of conflict of such sale with such holder’s material agreements and organizational documents, and with respect to written information relating to such
holder that such holder has furnished in writing expressly for inclusion in such Registration Statement. 
 3.1.7 Cooperation. The
principal executive officer of the Company, the principal financial officer of the Company, the principal accounting officer of the Company and all other officers and members of the management of the Company shall cooperate fully in any offering of
Registrable Securities hereunder, which cooperation shall include, without limitation, the preparation of the Registration Statement with respect to such offering and all other offering materials and related documents, and participation in meetings
with Underwriters, attorneys, accountants and potential investors. 
 3.1.8 Records. The Company shall make available for inspection
by the holders of Registrable Securities included in such Registration Statement, any Underwriter participating in any disposition pursuant to such registration statement and any attorney, accountant or other professional retained by any holder of
Registrable Securities included in such Registration Statement or any Underwriter, all financial and other records, pertinent corporate documents and properties of the Company, as shall be necessary to enable them to exercise their due diligence
responsibility, and cause the Company’s officers, directors and employees to supply all information requested by any of them in connection with such Registration Statement. 

3.1.9 Opinions and Comfort Letters. Upon request, the Company shall furnish to each holder of Registrable Securities included in any
Registration Statement a signed counterpart, addressed to such holder, of (i) any opinion of counsel to the Company delivered to any Underwriter and (ii) any comfort letter from the Company’s independent public accountants delivered
to any Underwriter. In the event no legal opinion is delivered to any Underwriter, the Company shall furnish to each holder of Registrable Securities included in such Registration Statement, at any time that such holder elects to use a prospectus,
an opinion of counsel to the Company to the effect that the Registration Statement containing such prospectus has been declared effective and that no stop order is in effect. 

3.1.10 Earnings Statement. The Company shall comply with all applicable rules and regulations of the Commission and the Securities Act,
and make available to its stockholders, as soon as practicable, an earnings statement covering a period of twelve (12) months, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158
thereunder. 
 3.1.11 Listing. The Company shall use its best efforts to cause all Registrable Securities included in any
registration to be listed on such exchanges or otherwise designated for trading in the same manner as similar securities issued by the Company are then listed or designated or, if no such similar securities are then listed or designated, in a manner
satisfactory to the holders of a majority of the Registrable Securities included in such registration. 

  
 9 

 3.1.12 Road Show. If the registration involves the registration of Registrable
Securities involving gross proceeds in excess of $5,000,000, the Company shall use its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably
requested by the Underwriter in any underwritten offering. 
 3.2 Obligation to Suspend Distribution. Upon receipt of any notice from
the Company of the happening of any event of the kind described in Section 3.1.4(iv), or, in the case of a resale registration on Form S-3 pursuant to Section 2.3 hereof, upon any suspension by the
Company, pursuant to a written insider trading compliance program adopted by the Company’s Board of Directors, of the ability of all “insiders” covered by such program to transact in the Company’s securities because of the
existence of material non-public information, each holder of Registrable Securities included in any registration shall immediately discontinue disposition of such Registrable Securities pursuant to the
Registration Statement covering such Registrable Securities until such holder receives the supplemented or amended prospectus contemplated by Section 3.1.4(iv) or the restriction on the ability of “insiders” to transact in the
Company’s securities is removed, as applicable, and, if so directed by the Company, each such holder will deliver to the Company all copies, other than permanent file copies then in such holder’s possession, of the most recent prospectus
covering such Registrable Securities at the time of receipt of such notice. 
 3.3 Registration Expenses. The Company shall bear all
costs and expenses incurred in connection with any Demand Registration pursuant to Section 2.1, any Piggy-Back Registration pursuant to Section 2.2, and any registration on Form S-3 effected pursuant
to Section 2.3, and all expenses incurred in performing or complying with its other obligations under this Agreement, whether or not the Registration Statement becomes effective, including, without limitation: (i) all registration and
filing fees; (ii) fees and expenses of compliance with securities or “blue sky” laws (including fees and disbursements of counsel in connection with blue sky qualifications of the Registrable Securities); (iii) printing expenses;
(iv) the Company’s internal expenses (including, without limitation, all salaries and expenses of its officers and employees); (v) the fees and expenses incurred in connection with the listing of the Registrable Securities as required
by Section 3.1.11; (vi) Financial Industry Regulatory Authority fees; (vii) fees and disbursements of counsel for the Company and fees and expenses for independent certified public accountants retained by the Company (including the
expenses or costs associated with the delivery of any opinions or comfort letters requested pursuant to Section 3.1.9); (viii) the reasonable fees and expenses of any special experts retained by the Company in connection with such registration
and (ix) the reasonable fees and expenses of one legal counsel selected by the holders of a majority-in-interest of the Registrable Securities included in such
registration. The Company shall have no obligation to pay any underwriting discounts or selling commissions attributable to the Registrable Securities being sold by the holders thereof, which underwriting discounts or selling commissions shall be
borne by such holders. Additionally, in an underwritten offering, all selling stockholders and the Company shall bear the expenses of the Underwriter pro rata in proportion to the respective amount of shares each is selling in such offering. 

3.4 Information. The holders of Registrable Securities shall provide such information as may reasonably be requested by the Company, or
the managing Underwriter, if 

  
 10 

 
any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the
Securities Act pursuant to Section 2 and in connection with the Company’s obligation to comply with Federal and applicable state securities laws. 

4. INDEMNIFICATION AND CONTRIBUTION. 

4.1 Indemnification by the Company. The Company agrees to indemnify and hold harmless each Stockholder and each other holder of
Registrable Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Stockholder and each other holder of Registrable Securities (within
the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, a “Stockholder Indemnified Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether
joint or several, arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities
Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission) to
state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and
relating to action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Stockholder Indemnified Party for any legal and any other expenses reasonably incurred by such Stockholder
Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss,
claim, damage or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any
such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein. The Company also shall indemnify any Underwriter of the Registrable Securities,
their officers, affiliates, directors, partners, members and agents and each person who controls such Underwriter on substantially the same basis as that of the indemnification provided above in this Section 4.1. 

4.2 Indemnification by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any
registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless the Company, each of its directors and officers and each Underwriter (if any),
and each other selling holder and each other person, if any, who controls another selling holder or such Underwriter within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, whether joint or several,
insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under
which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus 

  
 11 

 
contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material
fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by such selling holder
expressly for use therein, and shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigation or
defending any such loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling
holder. 
 4.3 Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage
or liability or any action in respect of which indemnity may be sought pursuant to Section 4.1 or 4.2, such person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other person for
indemnification hereunder, notify such other person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the
Indemnifying Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure.
If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes,
jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the
defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of
investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate
counsel) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and
expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing
interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the
Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out
of such claim or proceeding. 
 4.4 Contribution. 

4.4.1 If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any
loss, claim, damage, 

  
 12 

 
liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party
as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in
such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access
to information and opportunity to correct or prevent such statement or omission. 
 4.4.2 The parties hereto agree that it would not be just
and equitable if contribution pursuant to this Section 4.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding
Section 4.4.1. 
 4.4.3 The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action
referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action
or claim. Notwithstanding the provisions of this Section 4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts,
commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. 
 5.
[Reserved.] 
 6. RULE 144. 

6.1 Rule 144. The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange
Act and shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holders to sell Registrable Securities without registration under the Securities Act
within the limitation of the exemptions provided by Rule 144 under the Securities Act, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission. 

7. MISCELLANEOUS. 
 7.1
Other Registration Rights. The Company represents and warrants that, except as disclosed in the Company’s registration statement on Form S-1 (File
