      (n)          “Janus Investors” shall mean Investors, or permitted transferees of Registrable Securities held by Janus Investors, that are

        with this Agreement.

      SECTION 2

      

      

      REGISTRATION RIGHTS

      

      

      2.1  Requested Registration.

      

      

      (a)          Request for Registration. Subject to the conditions set forth in this Section 2.1, if the Company shall receive from
        Initiating Holders a written request signed by such Initiating Holders that the Company effect any registration with respect to all or a part of the Registrable Securities (such request shall state the number of shares of Registrable Securities to
        be disposed of and the intended methods of disposition of such shares by such Initiating Holders), the Company will:

      
        -3-

        
          


      

      (i)          promptly give written notice of the proposed registration to all other Holders; and

      

      

      (ii)          as soon as practicable, file and use its commercially reasonable efforts to effect such registration (including, without limitation, filing post-effective amendments, appropriate
        qualifications under applicable blue sky or other state securities laws, and appropriate compliance with the Securities Act) and to permit or facilitate the sale and distribution of all or such portion of such Registrable Securities as are
        specified in such request, together with all or such portion of the Registrable Securities of any Holder or Holders joining in such request as are specified in a written request received by the Company within twenty (20) days after such written
        notice from the Company is mailed or delivered.

      

      

      (b)          Limitations on Requested Registration. The Company shall not be obligated to effect, or to take any action to effect, any
        such registration pursuant to this Section 2.1:

      

      

      (i)          Prior to the earlier of (A) the four (4) year anniversary of the date of this Agreement or (B) 180 days following the effective date of the first registration statement filed by the
        Company covering an underwritten offering of any of its securities to the general public (or the subsequent date on which all market stand-off agreements applicable to the offering have terminated);

      

      

      (ii)          If the Initiating Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration statement, propose to sell Registrable
        Securities and such other securities (if any) the aggregate proceeds of which (after deduction for underwriter’s discounts and expenses related to the issuance) are less than $15,000,000;

      

      

      (iii)          In any particular jurisdiction in which the Company would be required to execute a general consent to service of process in effecting such registration, qualification, or
        compliance, unless the Company is already subject to service in such jurisdiction and except as may be required by the Securities Act;

      

      

      (iv)          After the Company has effected two such registrations pursuant to this Section 2.1;

      

      

      (v)          During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of filing of, and ending on a date one hundred eighty (180) days after
        the effective date of, a Company-initiated registration (or ending on the subsequent date on which all market stand-off agreements applicable to the offering have terminated); provided that the Company is
        actively employing in good faith commercially reasonable efforts to cause such registration statement to become effective;

      

      

      (vi)          If the Initiating Holders propose to dispose of shares of Registrable Securities that may be registered on Form S-3 pursuant to a request made under Section 2.3;

      

      

      (vii)          If the Initiating Holders do not request that such offering be firmly underwritten by underwriters selected by the Initiating Holders (subject to the reasonable consent of the
        Company); provided, however, that such requirement shall not apply in the event the Company requests inclusion pursuant to Section 2.1(d); and

      
        -4-

        
          


      

      (viii)          If the Company and the Initiating Holders are unable to obtain the commitment of the underwriter described in clause (b)(vii) above to firmly underwrite the offer.

      

      

      (c)          Deferral. If (i) in the good faith judgment of the board of directors of the Company, the filing of a registration statement
        covering the Registrable Securities would be materially detrimental to the Company and the board of directors of the Company concludes, as a result, that it is in the best interests of the Company to defer the filing of such registration statement
        at such time, and (ii) the Company shall furnish to such Holders a certificate signed by the President of the Company stating that in the good faith judgment of the board of directors of the Company, it would be materially detrimental to the
        Company for such registration statement to be filed in the near future and that it is, therefore, in the best interests of the Company to defer the filing of such registration statement, then (in addition to the limitations set forth in Section
        2.1(b)(v) above) the Company shall have the right to defer such filing, and the time periods with respect to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than 90 days after receipt of the request of the
        Initiating Holders, and, provided further, that the Company shall not defer its obligation in this manner more than two times in any twelve-month period.

      

      

      (d)          Underwriting. The right of any Holder to include all or any portion of its Registrable Securities in a registration pursuant
        to this Section 2.1 shall be conditioned upon such Holder’s participation in an underwriting and the inclusion of such Holder’s Registrable Securities to the extent provided herein. If the Company shall request inclusion in any registration
        pursuant to Section 2.1 of securities being sold for its own account, or if other persons shall request inclusion in any registration pursuant to Section 2.1, the Initiating Holders shall, on behalf of all Holders, offer to include such securities
        in the underwriting and such offer shall be conditioned upon the participation of the Company or such other persons in such underwriting and the inclusion of the Company’s and such person’s other securities of the Company and their acceptance of
        the further applicable provisions of this Section 2 (including Section 2.10). The Company shall (together with all Holders proposing to distribute their securities through such underwriting) enter into an underwriting agreement in customary form
        with the representative of the underwriter or underwriters selected for such underwriting by the Company, which underwriters are reasonably acceptable to a majority-in-interest of the Initiating Holders.

      

      

      Notwithstanding any other provision of this Section 2.1, if the underwriters advise the Initiating Holders in writing that marketing factors require a limitation on the number of shares to be
        underwritten, the number of Registrable Securities that may be so included shall be allocated as follows: (i) first, among all Holders requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, assuming conversion; and (ii) second, to the Company, which the Company may allocate, at its discretion, for its own account, or for the
        account of other holders or employees of the Company.

      

      

      If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall be excluded therefrom by written notice from
        the Company, the underwriter or the Initiating Holders. The securities so excluded shall also be withdrawn from registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall also be withdrawn from
        such registration. If shares are so withdrawn from the registration and if the number of shares to be included in such registration was previously reduced as a result of marketing factors pursuant to this Section 2.1(d), then the Company shall then
        offer to all Holders who have retained rights to include securities in the registration the right to include additional Registrable Securities in the registration in an aggregate amount equal to the number of shares so withdrawn, with such shares
        to be allocated among such Holders requesting additional inclusion, as set forth above.

      
        -5-

        
          


      

      For purposes of Section 2.1, a registration shall not be counted as “effected” if, as a result of an exercise of the underwriter’s cutback provisions in Section 2.2(b), fewer than all of the total
        number of Registrable Securities that Holders have requested to be included in such registration statement are actually included.

      

      

      2.2  Company Registration

       

      

      (a)          Company Registration. If the Company shall determine to register any of its securities either for its own account or the
        account of a security holder or holders, other than a registration pursuant to Section 2.1 or 2.3, a registration relating solely to employee benefit plans, a registration relating to the offer and sale of debt securities, a registration relating
        to a corporate reorganization or other Rule 145 transaction, or a registration on any registration form that does not permit secondary sales, the Company will:

      

      

      (i)          promptly give written notice of the proposed registration to all Holders; and

      

      

      (ii)          use its commercially reasonable efforts to include in such registration (and any related qualification under blue sky laws or other compliance), except as set forth in Section 2.2(b)
        below, and in any underwriting involved therein, all of such Registrable Securities as are specified in a written request or requests made by any Holder or Holders received by the Company within ten (10) days after such written notice from the
        Company is mailed or delivered. Such written request may specify all or a part of a Holder’s Registrable Securities.

      

      

      (b)          Underwriting. If the registration of which the Company gives notice is for a registered public offering involving an
        underwriting, the Company shall so advise the Holders as a part of the written notice given pursuant to Section 2.2(a)(i). In such event, the right of any Holder to registration pursuant to this Section 2.2 shall be conditioned upon such Holder’s
        participation in such underwriting and the inclusion of such Holder’s Registrable Securities in the underwriting to the extent provided herein. All Holders proposing to distribute their securities through such underwriting shall (together with the
        Company and other holders of securities of the Company with registration rights to participate therein distributing their securities through such underwriting) enter into an underwriting agreement in customary form with the representative of the
        underwriter or underwriters selected by the Company.

      

      

      Notwithstanding any other provision of this Section 2.2, if the underwriters advise the Company in writing that marketing factors require a limitation on the number of shares to be underwritten,
        the underwriters may (subject to the limitations set forth below) limit the number of Registrable Securities to be included in, the registration and underwriting. The Company shall so advise all holders of securities requesting registration, and
        the number of shares of securities that are entitled to be included in the registration and underwriting shall be allocated, as follows: (i) first, to the Company for securities being sold for its own account, and (ii) second, to the Holders
        requesting to include Registrable Securities in such registration statement based on the pro rata percentage of Registrable Securities held by such Holders, assuming conversion. Notwithstanding the
        foregoing, no such reduction shall reduce the value of the Registrable Securities of the Holders included in such registration below 30% of the total value of securities included in such registration, unless such offering is the Initial Public
        Offering and such registration does not include shares of any other selling stockholders (excluding shares registered for the account of the Company), in which event any or all of the Registrable Securities of the Holders may be excluded.

      

      

      If a person who has requested inclusion in such registration as provided above does not agree to the terms of any such underwriting, such person shall also be excluded therefrom by written notice
        from the Company or the underwriter. The Registrable Securities or other securities so excluded shall also be withdrawn from such registration. Any Registrable Securities or other securities excluded or withdrawn from such underwriting shall be
        withdrawn from such registration.

      
        -6-

        
          


      

      (c)          Right to Terminate Registration. The Company shall have the right to terminate or withdraw any registration initiated by it
        under this Section 2.2 prior to the effectiveness of such registration whether or not any Holder has elected to include securities in such registration.

      

      

      2.3  Registration on Form S-3

       

      

      (a)          Request for Form S‐3 Registration. After the Initial Public
        Offering, the Company shall use its commercially reasonable efforts to qualify for registration on Form S-3 or any comparable or successor form or forms. After the Company has qualified for the use of Form S-3, in addition to the rights contained
        in the foregoing provisions of this Section 2 and subject to the conditions set forth in this Section 2.3, if the Company shall receive from a Holder or Holders who in the aggregate hold at least 20% of the outstanding Registrable Securities a
        written request that the Company effect any registration on Form S‐3 or any similar short form registration statement with respect to all or part of the Registrable Securities (such request shall state the number of shares of Registrable Securities
        to be disposed of and the intended methods of disposition of such shares by such Holder or Holders), the Company will take all such action with respect to such Registrable Securities as required by Section 2.1(a)(i) and 2.1(a)(ii).

      

      

      (b)          Limitations on Form S‐3 Registration. The Company shall not be
        obligated to effect, or take any action to effect, any such registration pursuant to this Section 2.3:

      

      

      (i)          In the circumstances described in either Sections 2.1(b)(i), 2.1(b)(iii) or 2.1(b)(v);

      

      

      (ii)          If the Holders, together with the holders of any other securities of the Company entitled to inclusion in such registration, propose to sell Registrable Securities and such other
        securities (if any) on Form S‐3 at an aggregate price to the public of less than $3,000,000; or

      

      

      (iii)          If, in a given twelve-month period, the Company has effected two (2) such registrations in such period.

      

      

      (c)          Deferral. The provisions of Section 2.1(c) shall apply to any registration pursuant to this Section 2.3.

      

      

      (d)          Underwriting. If the Holders of Registrable Securities requesting registration under this Section 2.3 intend to distribute
        the Registrable Securities covered by their request by means of an underwriting, the provisions of Section 2.1(d) shall apply to such registration. Notwithstanding anything contained herein to the contrary, registrations effected pursuant to this
        Section 2.3 shall not be counted as requests for registration or registrations effected pursuant to Section 2.1.

      

      

      2.4  Expenses of Registration. All Registration Expenses incurred in connection with registrations pursuant to Sections 2.1, 2.2 and 2.3 shall be borne by the Company; provided,
        however, that the Company shall not be required to pay for any expenses of any registration proceeding begun pursuant to Sections 2.1 and 2.3 if the registration request is subsequently withdrawn at the
        request of the Holders of a majority of the Registrable Securities to be registered or because a sufficient number of Holders shall have withdrawn so that the minimum offering conditions set forth in Sections 2.1

        and 2.3 are no longer satisfied (in which case all participating Holders shall bear such expenses pro rata among each other based on the number of Registrable Securities requested to be so registered),
        unless the Holders of at least 77% of the Registrable Securities agree to forfeit their right to a demand registration pursuant to Section 2.1; provided, however,
        in the event that a withdrawal by the Holders is based upon material adverse information relating to the Company that is different from the information known to the Holders requesting registration at the time of their request for registration under
        Section 2.1, such registration shall not be treated as a counted registration for purposes of Section 2.1, even though the Holders do not bear the Registration Expenses for such registration. All Selling Expenses relating to securities registered
        on behalf of the Holders shall be borne by the holders of securities included in such registration pro rata among each other on the basis of the number of Registrable Securities so registered.

      
        -7-

        
          


      

      2.5  Registration Procedures. In the case of each registration effected by the Company pursuant to Section 2, the Company will keep each Holder advised in writing as to the initiation of each registration and
        as to the completion thereof. At its expense, the Company will use its commercially reasonable efforts to:

      

      

      (a)          Keep such registration effective for a period ending on the earlier of the date which is ninety (90) days from the effective date of the registration statement or such time as the
        Holder or Holders have completed the distribution described in the registration statement relating thereto; provided, however, that (i) such ninety (90) day period shall be extended for a period of time equal to the period the
        Holder refrains, at the request of an underwriter of Common Stock (or other securities) of the Company, from selling any securities included in such registration, and (ii) in the case of any registration of Registrable Securities on Form S-3 that
        are intended to be offered on a continuous or delayed basis, subject to compliance with applicable SEC rules, such ninety (90) day period shall be extended for up to one hundred eighty (180) days, if necessary, to keep the registration statement
        effective until all such Registrable Securities are sold;

      

      

      (b)          Prepare and file with the Commission such amendments and supplements to such registration statement and the prospectus used in connection with such registration statement as may be
        necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the period set forth in subsection (a) above;

      

      

      (c)          Furnish such number of prospectuses, including any preliminary prospectuses, and other documents incident thereto, including any amendment of or supplement to the prospectus, as a
        Holder from time to time may reasonably request;

      

      

      (d)          Use its reasonable best efforts to register and qualify the securities covered by such registration statement under such other securities or Blue Sky laws of such jurisdiction as shall
        be reasonably requested by the Holders; provided, that the Company shall not be required in connection therewith or as a condition thereto to qualify to do business or to file a general consent to service
        of process in any such states or jurisdictions;

      

      

      (e)          Promptly make available for inspection by the selling Holders, any underwriter(s) participating in any disposition pursuant to such registration statement, and any attorney or
        accountant or other agent retained by any such underwriter or selected by the selling Holders, all financial and other records, pertinent corporate documents, and properties of the Company, and cause the Company’s officers, directors, employees,
        and independent accountants to supply all information reasonably requested by any such seller, underwriter, attorney, accountant, or agent, in each case, as necessary or advisable to verify the accuracy of the information in such registration
        statement and to conduct appropriate due diligence in connection therewith;

      

      

      (f)          Notify each seller of Registrable Securities covered by such registration statement at any time when a prospectus relating thereto is required to be delivered under the Securities Act
        of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue statement of a material fact or omits to state a material fact required to be stated therein or
        necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing, and following such notification promptly prepare and furnish to such seller a reasonable number of copies of a supplement to or an
        amendment of such prospectus as may be necessary so that, as thereafter delivered to the purchasers of such shares, such prospectus shall not include an untrue statement of a material fact or omit to state a material fact required to be stated
        therein or necessary to make the statements therein not misleading or incomplete in light of the circumstances then existing;

      
        -8-

        
          


      

      (g)          Provide a transfer agent and registrar for all Registrable Securities registered pursuant to such registration statement and a CUSIP number for all such Registrable Securities, in each
        case not later than the effective date of such registration;

      

      

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

      

      

      (i)          After such registration statement becomes effective, notify each selling Holder of any request by the SEC that the Company amend or supplement such registration statement or
        prospectus.

      

      

      (j)          Cause all such Registrable Securities registered pursuant hereunder to be listed on each securities exchange on which similar securities issued by the Company are then listed; and

      

      

      (k)          In connection with any underwritten offering pursuant to a registration statement filed pursuant to Section 2.1, enter into an underwriting agreement in form reasonably necessary to
        effect the offer and sale of Common Stock, provided such underwriting agreement contains reasonable and customary provisions, and provided further, that each Holder
        participating in such underwriting shall also enter into and perform its obligations under such an agreement.

      

      

      2.6  Indemnification

       

      

      (a)          To the extent permitted by law, the Company will indemnify and hold harmless each Holder, each of its officers, directors and partners, legal counsel and accountants and each person
        controlling such Holder within the meaning of Section 15 of the Securities Act, with respect to which registration, qualification or compliance has been effected pursuant to this Section 2, and each underwriter, if any, and each person who controls
        within the meaning of Section 15 of the Securities Act any underwriter, against all expenses, claims, losses, damages and liabilities (or actions, proceedings or settlements in respect thereof) arising out of or based on: (i) any untrue statement
        (or alleged untrue statement) of a material fact contained or incorporated by reference in any prospectus, offering circular or other document (including any related registration statement, notification or the like) incident to any such
        registration, qualification or compliance, (ii) any omission (or alleged omission) to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any violation (or alleged
        violation) by the Company of the Securities Act, the Exchange Act, any state securities laws or any rule or regulation thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any offering
        covered by such registration, qualification or compliance, and the Company will reimburse each such Holder, each of its officers, directors, partners, legal counsel and accountants and each person controlling such Holder, each such underwriter and
        each person who controls any such underwriter, for any legal and any other expenses reasonably incurred in connection with investigating and defending or settling any such claim, loss, damage, liability or action; provided
        that the Company will not be liable in any such case to the extent that any such claim, loss, damage, liability, or action arises out of or is based on any untrue statement or omission based upon and in conformity with written information furnished
        to the Company by such Holder, any of such Holder’s officers, directors, partners, legal counsel or accountants, any person controlling such Holder, such underwriter or any person who controls any such underwriter, and stated to be specifically for
        use therein; and provided, further that, the indemnity agreement contained in this Section 2.6(a) shall not apply to amounts paid in settlement of any such loss,
        claim, damage, liability or action if such settlement is effected without the consent of the Company (which consent shall not be unreasonably withheld).

      
        -9-

        
          


      

      (b)          To the extent permitted by law, each Holder will, severally and not jointly, if Registrable Securities held by such Holder are included in the securities as to which such registration,
        qualification or compliance is being effected, indemnify and hold harmless the Company, each of its directors, officers, partners, legal counsel and accountants and each underwriter, if any, of the Company’s securities covered by such a
        registration statement, each person who controls the Company or such underwriter within the meaning of Section 15 of the Securities Act, each other such Holder, and each of their officers, directors and partners, and each person controlling each
        other such Holder, against all claims, losses, damages and liabilities (or actions in respect thereof) arising out of or based on: (i) any untrue statement (or alleged untrue statement) of a material fact contained or incorporated by reference in
        any prospectus, offering circular or other document (including any related registration statement, notification, or the like) incident to any such registration, qualification or compliance, or (ii) any omission (or alleged omission) to state
        therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and will reimburse the Company and such Holders, directors, officers, partners, legal counsel and accountants, persons, underwriters,
        or control persons for any legal or any other expenses reasonably incurred in connection with investigating or defending any such claim, loss, damage, liability or action, in each case to the extent, but only to the extent, that such untrue
        statement (or alleged untrue statement) or omission (or alleged omission) is made in such registration statement, prospectus, offering circular or other document in reliance upon and in conformity with written information furnished to the Company
        by such Holder and stated to be specifically for use therein; provided, however, that the obligations of such Holder hereunder shall not apply to amounts paid in
        settlement of any such claims, losses, damages or liabilities (or actions in respect thereof) if such settlement is effected without the consent of such Holder (which consent shall not be unreasonably withheld); and provided that in no event shall any indemnity under this Section 2.6 exceed the net proceeds from the offering received by such Holder, except in the case of fraud or willful misconduct by such Holder.

      

      

      (c)          Each party entitled to indemnification under this Section 2.6 (the “Indemnified Party”) shall give notice to the party required to provide indemnification (the “Indemnifying Party”) promptly after such Indemnified Party has actual knowledge of any claim as to which indemnity may be sought, and shall permit the Indemnifying Party to assume the defense of such claim
        or any litigation resulting therefrom; provided that counsel for the Indemnifying Party, who shall conduct the defense of such claim or any litigation resulting therefrom, shall be approved by the
        Indemnified Party (whose approval shall not be unreasonably withheld), and the Indemnified Party may participate in such defense at such party’s expense; provided, however, that an Indemnified Party
        (together with all other Indemnified Parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and expenses to be paid by the Indemnifying Party, if representation of such
        Indemnified Party by the counsel retained by the Indemnifying Party would be inappropriate due to actual or potential differing interests between such Indemnifying Party and any other party represented by such counsel in such action; and provided further that the failure of any Indemnified Party to give notice as provided herein shall not relieve the Indemnifying Party of its obligations under this
        Section 2.6, to the extent such failure is not prejudicial. No Indemnifying Party, in the defense of any such claim or litigation, shall, except with the consent of each Indemnified Party, consent to entry of any judgment or enter into any
        settlement that does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect to such claim or litigation. Each Indemnified Party shall furnish such
        information regarding itself or the claim in question as an Indemnifying Party may reasonably request in writing and as shall be reasonably required in connection with defense of such claim and litigation resulting therefrom.

      
        -10-

        
          


      

      (d)          If the indemnification provided for in this Section 2.6 is held by a court of competent jurisdiction to be unavailable to an Indemnified Party with respect to any loss, liability,
        claim, damage, or expense referred to herein, then the Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, liability,
        claim, damage, or expense in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and of the Indemnified Party on the other in connection with the statements or omissions that resulted in such
        loss, liability, claim, damage, or expense as well as any other relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference to, among other things, whether the untrue
        or alleged untrue statement of a material fact or the omission to state a material fact relates to information supplied by the Indemnifying Party or by the Indemnified Party and the parties’ relative intent, knowledge, access to information, and
        opportunity to correct or prevent such statement or omission. No person or entity will be required under this Section 2.6(d) to contribute any amount in excess of the net proceeds from the offering received by such person or entity, except in the
        case of fraud or willful misconduct by such person or entity. In no event shall a Holder’s liability pursuant to this Section 2.6(d), when combined with the amounts paid or payable by such Holder pursuant to Section 2.6(b), exceed the proceeds from
        the offering received by such Holder (net of any Selling Expenses paid by such Holder), except in the case of willful misconduct or fraud by such Holder. No person or entity guilty of fraudulent misrepresentation (within the meaning of Section
        11(f) of the Securities Act) will be entitled to contribution from any person or entity who was not guilty of such fraudulent misrepresentation.

      

      

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

      

      

      2.7  Information by Holder. Each Holder of Registrable Securities shall furnish to the Company such information regarding such Holder and the distribution proposed by such Holder as the Company may reasonably
        request in writing and as shall be reasonably required in connection with any registration, qualification, or compliance referred to in this Section 2.

      

      

      2.8  Restrictions on Transfer

      (a)          The holder of each certificate representing Registrable Securities, by acceptance of ownership thereof, agrees to comply in all respects with the provisions of this Section 2.8. Each
        Holder agrees not to make any sale, assignment, transfer, pledge or other disposition of all or any portion of the Restricted Securities, or any beneficial interest therein, unless and until the transferee thereof has agreed in writing for the
        benefit of the Company to take and hold such Restricted Securities subject to, and to be bound by, the terms and conditions set forth in this Agreement, including, without limitation, this Section 2.8 and Section 2.10, and:

      

      

      (i)          There is then in effect a registration statement under the Securities Act covering such proposed disposition and the disposition is made in accordance with the registration statement;
        or

      
        -11-

        
          


      

      (ii)          The Holder shall have given prior written notice to the Company of the Holder’s intention to make such disposition and shall have furnished the Company with a detailed description of
        the manner and circumstances of the proposed disposition, and, if requested by the Company, the Holder shall have furnished the Company, at the Holder’s expense, with (i) an opinion of counsel, reasonably satisfactory to the Company, to the effect
        that such disposition will not require registration of such Restricted Securities under the Securities Act or (ii) a “no action” letter from the Commission to the effect that the transfer of such securities without registration will not result in a
        recommendation by the staff of the Commission that action be taken with respect thereto, whereupon the holder of such Restricted Securities shall be entitled to transfer such Restricted Securities in accordance with the terms of the notice
        delivered by the Holder to the Company. It is agreed that the Company will not require opinions of counsel for transactions made pursuant to Rule 144, except in unusual circumstances.

      

      

      Notwithstanding the foregoing, the Company shall not require any transferee of shares pursuant to an effective registration statement or, following the Initial Public Offering, Rule 144 to be bound by the terms of
        this Agreement.

      

      

      (b)          Notwithstanding the provisions of Section 2.8(a), no such registration statement, opinion of counsel, or “no action” letter shall be necessary for (i) a transfer not involving a change
        in beneficial ownership, or (ii) transactions involving the distribution without consideration of Restricted Securities by any Holder to (x) a parent, subsidiary or other Affiliate of the Holder, if the Holder is a corporation, (y) any of the
        Holder’s partners, members or other equity owners, or retired partners, retired members or other equity owners, or to the estate of any of the Holder’s partners, members or other equity owners or retired partners, retired members or other equity
        owners, or (z) a venture capital fund or other investment fund that is controlled by or under common control with one or more general partners or managing members of, or shares the same management company with, the Holder; provided, in each case, that the Holder shall give written notice to the Company of the Holder’s intention to effect such disposition and shall have furnished the Company with a detailed description of the manner and circumstances
        of the proposed disposition.

      

      

      (c)          Each certificate representing Registrable Securities shall (unless otherwise permitted by the provisions of this Agreement) be stamped or otherwise imprinted with a legend
        substantially similar to the following (in addition to any legend required under applicable state securities laws):

      

      

      THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “ACT”), OR UNDER THE SECURITIES LAWS OF CERTAIN
        STATES. THESE SECURITIES MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED EXCEPT AS PERMITTED UNDER THE ACT AND APPLICABLE STATE SECURITIES LAWS PURSUANT TO REGISTRATION OR AN EXEMPTION THEREFROM. THE ISSUER OF THESE
        SECURITIES MAY REQUIRE AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER THAT SUCH OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION OTHERWISE COMPLIES WITH THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

      

      

      THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO (1) RESTRICTIONS ON TRANSFERABILITY AND RESALE, INCLUDING A LOCK-UP PERIOD IN THE EVENT OF A PUBLIC OFFERING, AS SET FORTH IN AN INVESTORS’ RIGHTS
        AGREEMENT, AND (2) VOTING RESTRICTIONS AS SET FORTH IN A VOTING AGREEMENT AMONG THE COMPANY AND THE ORIGINAL HOLDERS OF THESE SHARES, COPIES OF WHICH MAY BE OBTAINED AT THE PRINCIPAL OFFICE OF THE COMPANY.

      
        -12-

        
          


      

      (d)          The first legend referring to federal and state securities laws identified in Section 2.8(b) stamped on a certificate evidencing the Restricted Securities and the stock transfer
        instructions and record notations with respect to the Restricted Securities shall be promptly removed, and the Company shall issue a certificate without such legend to the holder of Restricted Securities, if (i) those securities are registered
        under the Securities Act, or (ii) the holder provides the Company with an opinion of counsel reasonably acceptable to the Company to the effect that a sale or transfer of those securities may be made without registration, qualification or legend.

      

      

      (e)          Each Investor agrees not to make any sale, assignment, transfer, pledge or other disposition of any securities of the Company, or any beneficial interest therein, to (i) any person
        whom the Board of Directors of the Company (the “Board of Directors”), including at least one Preferred Director, reasonably determines to be a competitor, or an officer, director, or holder of more than 10%
        of a competitor (each, a “Competitor”); provided, however, that for purposes of this Agreement, no person or entity or any of its Affiliates that is a venture capital
        fund or other investment fund whose primary business is making investments in operating companies shall be deemed a Competitor of the Company (or an officer, director, or holder of more than 10% of a Competitor), or to (ii) any person other than
        the Company unless and until the proposed transferee confirms to the reasonable satisfaction of the Company that neither the proposed transferee nor any of its directors, executive officers, other officers that may serve as a director or officer of
        any company in which it invests, general partners or managing members nor any person that would be deemed a beneficial owner of those securities (in accordance with Rule 506(d) of the Securities Act) is subject to any Bad Actor Disqualification,
        except as set forth in Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act and disclosed, reasonably in advance of the transfer, in writing in reasonable detail to the Company.

      

      

      (f)          The Company shall not be obligated to recognize any attempted sale, assignment, transfer, pledge or other disposition of all or any portion of the Restricted Securities, or any
        beneficial interest therein, made other than in compliance with the terms and conditions of this Agreement. The Holders consent to the Company making a notation on its records and giving instructions to any transfer agent of the Restricted
        Securities in order to implement the restrictions on transfer established in this Agreement.

      

      

      2.9  Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the Commission that may permit the sale of the Restricted Securities to the public without registration,
        the Company agrees to use its commercially reasonable efforts to:

      

      

      (a)          Make and keep adequate current public information with respect to the Company available in accordance with Rule 144 under the Securities Act, at all times from and after ninety (90)
        days following the effective date of the first registration under the Securities Act filed by the Company for an offering of its securities to the general public;

      

      

      (b)          File with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act at any time after it has become
        subject to such reporting requirements; and

      
        -13-

        
          


      

      (c)          So long as a Holder owns any Restricted Securities, furnish to the Holder forthwith upon written request a written statement by the Company as to its compliance with the reporting
        requirements of Rule 144 (at any time from and after ninety (90) days following the effective date of the first registration statement filed by the Company for an offering of its securities to the general public), and of the Securities Act and the
        Exchange Act (at any time after it has become subject to such reporting requirements), a copy of the most recent annual or quarterly report of the Company, and such other reports and documents so filed as a Holder may reasonably request in availing
        itself of any rule or regulation of the Commission allowing a Holder to sell any such securities without registration.

      

      

      2.10  Market Stand-Off Agreement. Each Holder shall not, without the prior written consent of the Company and the managing underwriter of the Initial Public Offering, sell or otherwise transfer, make any short
        sale of, grant any option for the purchase of, or enter into any hedging or similar transaction with the same economic effect as a sale, of any Common Stock (or other securities) of the Company held by such Holder (other than those included in the
        registration) during the period from the filing of the registration statement for the Initial Public Offering filed under the Securities Act that includes securities to be sold on behalf of the Company to the public in an underwritten public
        offering under the Securities Act through the end of the 180-day period following the filing of the final prospectus, provided that all officers and directors of the Company and all holders of at least 1%
        of the Company’s voting securities are bound by and have entered into similar agreements. The Company may impose stop-transfer instructions and may stamp each such certificate with the second legend set forth in Section 2.8(c) with respect to the
        shares of Common Stock (or other securities) subject to the foregoing restriction until the end of such one hundred eighty (180) day (or other) period. Each Holder agrees to execute a market standoff agreement with said underwriters in customary
        form consistent with the provisions of this Section 2.10.  Any discretionary waiver or termination of the restrictions of any or all of such agreements by the Company or the underwriters shall apply pro rata to all Company stockholders that are
        subject to such agreements, based on the number of shares subject to such agreements, except that, notwithstanding the foregoing, the Company and the underwriters may, in their sole discretion, waive or terminate these restrictions with respect to
        up to $1,000,000 of shares of the Common Stock. Notwithstanding the foregoing, the obligations in this Section 2.10 shall not apply to shares acquired by a Holder either in the Initial Public Offering or on the open market following the Initial
        Public Offering, or to the sale of any shares to an underwriter pursuant to an underwriting agreement.

      

      

      2.11  Delay of Registration. No Holder shall have any right to take any action to restrain, enjoin, or otherwise delay any registration as the result of any controversy that might arise with respect to the
        interpretation or implementation of this Section 2.

      

      

      2.12  Transfer or Assignment of Registration Rights. The rights to cause the Company to register securities granted to a Holder by the Company under this Section 2 may be transferred or assigned by a Holder only
        with the prior written consent of the Company, to an Affiliate of such Holder or to a transferee or assignee of not less than 1,000,000 shares of Registrable Securities (as presently constituted and subject to subsequent adjustments for stock
        splits, stock dividends, reverse stock splits, and the like) (each a “Permitted Transferee”); provided that (i) such transfer or assignment of
        Registrable Securities is effected in accordance with the terms of Section 2.8, the Right of First Refusal and Co-Sale Agreement, and applicable securities laws, (ii) the Company is given written notice prior to said transfer or assignment, stating
        the name and address of the transferee or assignee and identifying the securities with respect to which such registration rights are intended to be transferred or assigned, (iii) the transferee or assignee of such rights assumes in writing the
        obligations of such Holder under this Agreement, including without limitation the obligations set forth in Section 2.10, and (iv) the proposed transferee or assignee of such rights is not a Competitor of the Company.

      

      

      2.13  Limitations on Subsequent Registration Rights. From and after the date of this Agreement, the Company shall not, without the prior written consent of Holders holding at least 77% of the Registrable
        Securities (excluding any of such shares held by any Holders whose rights to request registration or inclusion in any registration pursuant to this Section 2 have terminated in accordance with Section 2.14), enter into any agreement with any holder
        or prospective holder of any securities of the Company giving such holder or prospective holder any registration rights the terms of which are pari passu or senior to the registration rights granted to the
        Holders hereunder.

      
        -14-

        
          


      

      2.14 Termination of Registration Rights. The right of any
        Holder to request registration or inclusion in any registration pursuant to Sections 2.1, 2.2 or 2.3 shall terminate on the earlier of (i) such date, on or after the closing of the Initial Public Offering, on
        which all shares of Registrable Securities held or entitled to be held upon conversion by such Holder may immediately be sold under Rule 144 during any ninety (90) day period and (ii) four (4) years after the closing of the Initial Public Offering.

      

      

      SECTION 3

      

      

      INFORMATION COVENANTS

      

      

      3.1  Basic Financial Information and Inspection Rights

      

      

      (a)          Basic Financial Information. The Company will furnish the following reports to each Holder that, individually or together
        with such Holder’s Affiliates, holds at least 1,000,000 Shares or Conversion Stock (as presently constituted and subject to subsequent adjustments for stock splits, stock dividends, reverse stock splits and the like) (the “Significant Holders”):

      (ii)          As soon as practicable after the end of the first, second and third quarterly accounting periods in each fiscal year of the Company, and in any event within forty-five (45) days
        after the end of the first, second, and third quarterly accounting periods in each fiscal year of the Company, an unaudited consolidated balance sheet of the Company and its subsidiaries, if any, as of the end of each such quarterly period, and
        unaudited consolidated statements of income and cash flows of the Company and its subsidiaries, if any, for such period, prepared in accordance with U.S. generally accepted accounting principles consistently applied, subject to changes resulting

        or exercisable for Common Stock, and the number of shares of issued stock options and stock options not yet issued but reserved for issuance, if any, all in sufficient detail as to permit the respective Investor to calculate their respective
        percentage equity ownership in the Company; and

      
        -15-

        
          


      

      (v)          At least thirty (30) days prior to the beginning of each fiscal year, an annual budget and business plan for such fiscal year.

      

      

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

      

      

      (b)          Inspection Rights. The Company will afford to each Significant Holder and to such Significant Holder’s accountants and
        counsel, reasonable access during normal business hours to all of the Company’s respective properties, books and records. Each Significant Holder shall have such other access to management and information as is necessary for it to comply with
        applicable laws and regulations and reporting obligations. The Company shall not be required to disclose details of contracts with or work performed for specific customers and other business partners where to do so would violate confidentiality
        obligations to those parties. Significant Holders may exercise their rights under this Section 3.1(b) only for purposes reasonably related to their interests as a stockholder or under this Agreement and related agreements. The rights granted
        pursuant to this Section 3.1(b) may not be assigned or otherwise conveyed by the Holders or by any subsequent transferee of any such rights without the prior written consent of the Company except to Permitted Transferees.

      

      

      3.2  Confidentiality. Anything in this Agreement to the contrary notwithstanding, no Holder by reason of Section 3.1(b) shall have access to any trade secrets or classified information of the Company unless
        covered by an enforceable confidentiality agreement. The Company shall not be required to comply with any information rights of Section 3 in respect of any Holder who is a Competitor. Each Holder acknowledges that the information received by them
        pursuant to this Agreement may be confidential and for its use only, and it will not use such confidential information in violation of the Exchange Act or reproduce, disclose or disseminate such information to any other person (other than as
        provided below), except in connection with the exercise of rights under this Agreement, or unless such information (a) is known or becomes known to the public in general (other than as a result of a breach of this Section 3.2 by such Holder), (b)
        is or has been independently developed or conceived by such Holder, without use of the Company’s confidential information, and as demonstrated by contemporaneous written records, or (c) is or has been made known or disclosed to such Holder by a
        third party on a non-confidential basis and without a breach of any obligation of confidentiality such third party may have to the Company. A Holder may disclose the Company’s confidential information (i) to its attorneys, accountants, consultants,
        and other professionals to the extent necessary to obtain their services in connection with monitoring its investment in the Company and provided that such persons agree to be bound by the provisions of this Section 3.2 or are otherwise bound by an
        agreement or applicable law to maintain such information in confidence; (ii) to any prospective purchaser of any Registrable Securities from such Holder, if such prospective purchaser agrees to be bound by the provisions of this Section 3.2; (iii) to any existing or prospective Affiliate, partner, member, stockholder, or wholly owned subsidiary of such Holder if necessary in the ordinary course of business in order to monitor, or report on the
        status of, such Holder’s investment in the Company, provided that such Holder informs such person or entity that such information is confidential and directs such person or entity to maintain the
        confidentiality of such information; or (iv) to the extent required in connection with any routine or periodic examination or similar process by any regulatory or self-regulatory body or authority not specifically directed at the Company or the
        confidential information obtained from the Company pursuant to the terms of the Agreement, including, without limitation, quarterly or annual reports, or (v) as may otherwise be required by law, regulation, rule, court order or subpoena, provided that, with respect to this clause (v), such Holder promptly notifies the Company of such required disclosure and takes reasonable steps to minimize the extent of any such required disclosure.

      
        -16-

        
          


      

      3.3  Matters Requiring Investor Director Approval. So long as the holders of Preferred Stock or any series thereof are entitled to elect a Preferred Director, the Company hereby covenants and agrees with each
        of the Investors that it shall not, without approval of the Board of Directors, including at least one Preferred Director, enter into, be a party to, or amend, modify or terminate any transaction or agreement with Fount Therapeutics, LLC, Fount
        Service Corp. or any affiliate or subsidiary of the foregoing.

      

      

      3.4  Termination of Covenants. The covenants set forth in this Section 3 shall terminate and be of no further force and effect immediately before the closing of the Initial Public Offering.

      

      

      SECTION 4

      

      

      RIGHT OF FIRST REFUSAL

      

      

      4.1  Right of First Refusal to Significant Holders. The Company hereby grants to each Significant Holder the right of first refusal to purchase its pro rata share of
        New Securities (as defined in this Section 4.1(a)) which the Company may, from time to time, propose to sell and issue after the date of this Agreement. A Significant Holder’s pro rata share, for purposes
        of this right of first refusal, is equal to the ratio of (a) the number of shares of Common Stock owned by such Significant Holder immediately prior to the issuance of New Securities (assuming full conversion of the Shares and full conversion or
        exercise of all outstanding convertible securities, rights, options and warrants held by such Significant Holder) to (b) the total number of shares of Common Stock outstanding immediately prior to the issuance of New Securities (assuming full
        conversion of the Shares and full conversion or exercise of all outstanding convertible securities, rights, options and warrants and all securities reserved for issuance under the Company’s stock plans). Each Significant Holder shall have a right
        of over-allotment such that if any Significant Holder fails to exercise its right hereunder to purchase its pro rata share of New Securities, the other Significant Holders may purchase the non-purchasing
        Significant Holder’s portion on a pro rata basis. This right of first refusal shall be subject to the following provisions:

      

      

      (a)          “New Securities” shall mean any capital stock (including Common Stock and/or Preferred Stock) of the Company whether now
        authorized or not, and rights, convertible securities, options or warrants to purchase such capital stock, and securities of any type whatsoever that are, or may become, exercisable or convertible into capital stock; provided that the term “New Securities” does not include any securities excluded from the definition of “Additional Shares of Common” in the Restated Certificate (as
        defined below).

      

      

      (b)          In the event the Company proposes to undertake an issuance of New Securities, it shall give each Significant Holder written notice of its intention, describing the type of New
        Securities, and their price and the general terms upon which the Company proposes to issue the same. Each Significant Holder shall have ten (10) days after any such notice is delivered to agree to purchase such Holder’s pro rata share of such New Securities and to indicate whether such Holder desires to exercise its over‐allotment option for the price and upon the terms specified in the notice by giving written notice to the Company, in
        substantially the form attached as Schedule 1, and stating therein the quantity of New Securities to be purchased.

      

      

      (c)          In the event the Holders fail to exercise fully the right of first refusal and over‐allotment rights, if any, within said ten (10) day period (the “Election Period”), the Company shall have ninety (90) days thereafter to sell or enter into an agreement (pursuant to
        which the sale of New Securities covered thereby shall be closed, if at all, within ninety (90) days from the date of said agreement) to sell that portion of the New Securities with respect to which the Significant Holders’ right of first refusal
        option set forth in this Section 4.1 was not exercised, at a price and upon terms no more favorable to the purchasers thereof than specified in the Company’s notice to Significant Holders delivered pursuant to Section 4.1(b). In the event the
        Company has not sold within such ninety (90) day period following the Election Period, or such ninety (90)day period following the date of said agreement, the Company shall not thereafter issue or sell any New Securities, without first again
        offering such securities to the Significant Holders in the manner provided in this Section 4.1.

      
        -17-

        
          


      

      

      

      (d)          The right of first refusal granted under this Agreement shall expire upon, and shall not be applicable to, the Company’s Initial Public Offering. Subject to Section 2.12 above, the
        right of first refusal granted under this Agreement may be assigned or transferred, in whole or in part, by any Significant Holder to any Permitted Transferee.

      

      

      (e)          A Holder will not have a right of first refusal to purchase a pro rata share of New Securities in accordance with this Section 4 and will not
        be a Significant Holder for purposes of the right of first refusal granted under this Section 4 if, and for so long as, the Holder, any of its directors, executive officers, other officers that may serve as a director or officer of any company in
        which it invests, general partners or managing members or, to such Holder’s knowledge, any person that would be deemed a beneficial owner of the securities of the Company held by the Holder (in accordance with Rule 506(d) of the Securities Act) is
        subject to any Bad Actor Disqualification, except as set forth in Rule 506(d)(2)(ii) or (iii) or (d)(3) under the Securities Act.

      

      

      SECTION 5

      5.1  Directors and Officers Liability Insurance. The Company shall maintain a directors and officers liability insurance policy in the amount and with terms acceptable to the Board of Directors, including at
        least one of the Preferred Directors (as defined in the Company’s Amended and Restated Certificate of Incorporation, as may be amended from time to time (the “Restated Certificate”)).

      

      

      5.2  Reimbursement to Outside Directors. The Company shall reimburse outside directors for all reasonable expenses incurred in their services as a director of the Company in accordance with the Company’s
        standard policies and procedures.

        shares of early exercised stock options at cost. The Company’s Equity Incentive Plan shall provide that the Board has the ultimate discretion with respect to the treatment of options in a Deemed Liquidation Event (as defined in the Restated
        Certificate). In addition, at the time of a Deemed Liquidation Event, all unallocated options shall be terminated.

      

      

      5.4  Board Matters. The Company hereby agrees that each committee of the Company’s board of directors shall include at least one director nominated by the holders of Series B Preferred Stock.

        of the above-referenced agreements, without the approval of the Board of Directors, including at least one Preferred Director.

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

      

      

      5.7  Right to Conduct Activities. The Company hereby agrees and acknowledges that each of RA Capital Management, L.P., Viking Global Opportunities Illiquid Investments Sub-Master LP, Venrock Healthcare Capital

        is a professional investment organization, and as such reviews the business plans and related proprietary information of many enterprises, some of which may compete directly or indirectly with the Company’s business (as currently conducted or as
        currently propose to be conducted). The Company hereby agrees that, to the extent permitted under applicable law, each Fund (and its Affiliates) shall not be liable to the Company for any claim arising out of, or based upon, (i) the investment by
        any Fund (or its Affiliates) in any entity competitive with the Company, or (ii) actions taken by any partner, officer, employee or other representative of any Fund (or its Affiliates) to assist any such competitive company, whether or not such
        action was taken as a member of the board of directors of such competitive company or otherwise, and whether or not such action has a detrimental effect on the Company; provided, however, that the foregoing shall not relieve (x) any of the
        Investors from liability associated with the unauthorized disclosure of the Company’s confidential information obtained pursuant to this Agreement, or (y) any director or officer of the Company from any liability associated with his or her
        fiduciary duties to the Company.

      

      

      5.8  Termination of Additional Covenants. The covenants set forth in this Section 5 (other than Sections 5.7 and 5.9) shall terminate and be of no further force and effect immediately prior to the closing of

        Company constitutes a United States real property interest.  The Company’s determination shall comply with the requirements of Treasury Regulation Section 1.897-2(h)(1) or any successor regulation, and the Company shall provide timely notice to the
        Internal Revenue Service, in accordance with and to the extent required by Treasury Regulation Section 1.897-2(h)(2) or any successor regulation, that such statement has been made.  The Company’s written statement to an Investor shall be delivered
        to such Investor within ten (10) days of such Investor’s written request therefor.  The Company’s obligation to furnish such written statement shall continue notwithstanding the fact that a class of the Company’s stock may be regularly traded on an
        established securities market or the fact that there is no Preferred Stock then outstanding.

      SECTION 6

      

      

      MISCELLANEOUS

      

      

      6.1  Amendment. Except as expressly provided herein, neither this Agreement nor any term hereof may be amended, waived, discharged or terminated other than by a written instrument referencing this Agreement and
        signed by the Company and the Holders holding at least 77% of the Common Stock issued or issuable upon conversion of the Shares (excluding any of such shares that have been sold to the public either pursuant to a registration statement or,
        following the Initial Public Offering, pursuant to Rule 144, and excluding, with respect to Section 2 (other than Sections 2.8, 2.9 and 2.10), any of such shares held by any Holders whose rights to request registration or inclusion in any
        registration pursuant to Section 2 have terminated in accordance with Section 2.14); provided, however, that Holders purchasing shares of Series C Preferred Stock
        in a Closing after the Initial Closing (each as defined in the Purchase Agreement) may become parties to this Agreement, by executing a counterpart of this Agreement without any amendment of this Agreement pursuant to this paragraph or any consent
        or approval of any other Holder. Any such amendment, waiver, discharge or termination effected in accordance with this paragraph shall be binding upon each Holder and each future holder of all such securities of Holder. Each Holder acknowledges
        that by the operation of this paragraph, the holders of at least 77% of the Common Stock issued or issuable upon conversion of the Shares (excluding any of such shares that have been sold to the public either pursuant to a registration statement
        or, following the Initial Public Offering, pursuant to Rule 144, and excluding, with respect to Section 2 (other than Sections 2.8, 2.9 and 2.10), any of such shares held by any Holders whose rights to request registration or inclusion in any
        registration pursuant to Section 2 have terminated in accordance with Section 2.14) will have the right and power to diminish or eliminate all rights of such Holder under this Agreement. Notwithstanding the foregoing, the definition of “Affiliate”
        (as it pertains to the Janus Investors), the definition of “Janus Investors,” and this sentence of Section 6.1 shall not be amended, modified, terminated or waived without the prior written consent of the Janus Investors. Notwithstanding the
        foregoing, this Agreement may not be amended, modified or terminated and the observance of any term hereof may not be waived with respect to any Holder without the written consent of such Holder, unless such amendment, modification, termination, or
        waiver applies to all Holders in the same fashion (it being agreed that a waiver of the provisions of Section 4.1 with respect to a particular transaction shall be deemed to apply to all Holders in the same fashion if such waiver does so by its
        terms, notwithstanding the fact that certain Holders may nonetheless, by agreement with the Company, purchase securities in such transaction; provided, however, that if, after giving effect to such waiver of Section 4.1 with respect to a particular
        transaction, a Significant Holder purchases securities in such transaction or issuance (such Significant Holder, a “Participating Investor”), such waiver of the provisions of Section 4.1
        shall be deemed to apply to each other Significant Holder whose rights were waived or amended only if such other Significant Holder has been provided the opportunity to purchase a proportional number of the New Securities being offered by the
        Company in such transaction based on the pro rata purchase right of such other Significant Holder set forth in Section 4.1, assuming a transaction size determined based upon the amount purchased by the Participating Investor that invested the
        largest percentage in such transaction, it being agreed that such opportunity may be provided subsequent to the initial closing in which such Participating Investor(s) purchase securities).

      

      

      6.2  Notices. All notices and other communications required or permitted hereunder shall be in writing and shall be mailed by registered or certified mail, postage prepaid, sent by facsimile or electronic mail
        (if to an Investor or Holder) or otherwise delivered by hand, messenger or courier service addressed:

      

      

      (a)          if to an Investor, to the Investor’s address, facsimile number or electronic mail address as shown in the Company’s records, as may be updated in accordance with the provisions hereof;

      
        -20-

        
          


      

      

      

      (b)          if to any Holder, to such address, facsimile number or electronic mail address as shown in the Company’s records, or, until any such Holder so furnishes an address, facsimile number or
        electronic mail address to the Company, then to the address, facsimile number or electronic mail address of the last holder of such shares for which the Company has contact information in its records; or

      

      

      (c)          if to the Company, to the attention of the Chief Executive Officer or General Counsel of the Company at 11975 El Camino Real, Ste 101, San Diego, CA 92103, or at such other current
        address as the Company shall have furnished to the Investors or Holders, with a copy (which shall not constitute notice) to Kenneth Clark, Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, CA 94304-1050.

      

      

      Each such notice or other communication shall for all purposes of this Agreement be treated as effective or having been given (i) if delivered by hand, messenger or courier service, when delivered
        (or if sent via a nationally-recognized overnight courier service, freight prepaid, specifying next-business-day delivery, one business day after deposit with the courier), or (ii) if sent via mail, at the earlier of its receipt or five days after
        the same has been deposited in a regularly-maintained receptacle for the deposit of the United States mail, addressed and mailed as aforesaid, or (iii) if sent via facsimile, upon confirmation of facsimile transfer or, if sent via electronic mail,
        upon confirmation of delivery when directed to the relevant electronic mail address, if sent during normal business hours of the recipient, or if not sent during normal business hours of the recipient, then on the recipient’s next business day. In
        the event of any conflict between the Company’s books and records and this Agreement or any notice delivered hereunder, the Company’s books and records will control absent fraud or error.

      

      

      Subject to the limitations set forth in Delaware General Corporation Law §232(e), each Investor and Holder consents to the delivery of any notice to stockholders given by the Company under the
        Delaware General Corporation Law or the Company’s certificate of incorporation or bylaws by (i) facsimile telecommunication to the facsimile number set forth on Exhibit A (or to any other facsimile number for the Investor or Holder in the Company’s
        records), (ii) electronic mail to the electronic mail address set forth on Exhibit A (or to any other electronic mail address for the Investor or Holder in the Company’s records), (iii) posting on an electronic network together with separate notice
        to the Investor or Holder of such specific posting or (iv) any other form of electronic transmission (as defined in the Delaware General Corporation Law) directed to the Investor or Holder. This consent may be revoked by an Investor or Holder by
        written notice to the Company and may be deemed revoked in the circumstances specified in Delaware General Corporation Law §232.

      

      

      6.3  Governing Law. This Agreement shall be governed in all respects by the internal laws of the State of California as applied to agreements entered into among California residents to be performed entirely
        within California, without regard to principles of conflicts of law.

      

      

      6.4  Successors and Assigns. This Agreement, and any and all rights, duties and obligations hereunder, shall not be assigned, transferred, delegated or sublicensed by any Investor without the prior written
        consent of the Company, except to a Permitted Transferee. Any attempt by an Investor without such permission to assign, transfer, delegate or sublicense any rights, duties or obligations that arise under this Agreement shall be void. Subject to the
        foregoing and except as otherwise provided herein, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the successors, assigns, heirs, executors and administrators of the parties hereto.

      

      

      6.5  Entire Agreement. This Agreement and the exhibits hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof. No party hereto shall be liable
        or bound to any other party in any manner with regard to the subjects hereof or thereof by any warranties, representations or covenants except as specifically set forth herein.

      
        -21-

        
          


      

      6.6  Delays or Omissions. Except as expressly provided herein, no delay or omission to exercise any right, power or remedy accruing to any party to this Agreement upon any breach or default of any other party
        under this Agreement shall impair any such right, power or remedy of such non-defaulting party, nor shall it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or default thereafter
        occurring, nor shall any waiver of any single breach or default be deemed a waiver of any other breach or default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of any party of any
        breach or default under this Agreement, or any waiver on the part of any party of any provisions or conditions of this Agreement, must be in writing and shall be effective only to the extent specifically set forth in such writing. All remedies,
        either under this Agreement or by law or otherwise afforded to any party to this Agreement, shall be cumulative and not alternative.

      

      

      6.7  Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, portions of such provision, or such provision in its
        entirety, to the extent necessary, shall be severed from this Agreement, and such court will replace such illegal, void or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible,
        the same economic, business and other purposes of the illegal, void or unenforceable provision. The balance of this Agreement shall be enforceable in accordance with its terms.

      

      

      6.8  Titles and Subtitles. The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement. All references in this
        Agreement to sections, paragraphs and exhibits shall, unless otherwise provided, refer to sections and paragraphs hereof and exhibits attached hereto.

      

      

      6.9  Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be enforceable against the parties that execute such counterparts, and all of which together shall constitute
        one instrument.

      

      

      6.10  Telecopy Execution and Delivery. A facsimile, telecopy or other reproduction of this Agreement may be executed by one or more parties hereto and delivered by such party by facsimile or any similar
        electronic transmission device pursuant to which the signature of or on behalf of such party can be seen. Such execution and delivery shall be considered valid, binding and effective for all purposes. At the request of any party hereto, all parties
        hereto agree to execute and deliver an original of this Agreement as well as any facsimile, telecopy or other reproduction hereof.

      

      

      6.11  Jurisdiction; Venue. With respect to any disputes arising out of or related to this Agreement, the parties consent to the exclusive jurisdiction of, and venue in, the state courts in San Diego County in

      6.12  Further Assurances. Each party hereto agrees to execute and deliver, by the proper exercise of its corporate, limited liability company, partnership or other powers, all such other and additional
        instruments and documents and do all such other acts and things as may be necessary to more fully effectuate this Agreement.

      

      

      6.13  Termination Upon Change of Control. Notwithstanding anything to the contrary herein, this Agreement (excluding any then‐existing obligations) shall terminate upon a Deemed Liquidation Event (as defined in
        the Restated Certificate, as amended, modified or restated from time to time).

      
        -22-

        
          


      

      6.14  Conflict. In the event of any conflict between the terms of this Agreement and the Company’s Restated Certificate or its bylaws, the terms of the Company’s Restated Certificate or its bylaws, as the case
        may be, will control.

        reasonable fees and expenses of attorneys and accountants, which shall include, without limitation, all fees, costs and expenses of appeals.

      

      

      6.16  Aggregation of Stock. All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the purpose of determining the availability of any rights under this Agreement and
        such Affiliated persons may apportion such rights as among themselves in any manner they deem appropriate.

      

      

      6.17  Amendment and Restatement of Prior Agreement. The Prior Agreement is hereby amended in its entirety and restated herein. All provisions of, rights granted and covenants made in the Prior Agreement are
