    CHANGE IN CONTROL AND SEVERANCE AGREEMENT

      effective as of the Effective Date, as defined in Section 7 below.

    

    

    This Agreement provides certain protections to Executive in connection with a change in control of the Company or in connection with the termination of Executive’s employment under the circumstances

    2.

    At-Will Employment.  The Company and Executive acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law.  No payments,
      benefits, or provisions under this Agreement will confer upon Executive any right to continue Executive’s employment with the Company, nor will they interfere with or limit in any way the right of the Company or Executive to terminate such
      relationship at any time, with or without cause, to the extent permitted by applicable laws.

    

    

    3.

    Salary Severance.  A single, lump sum, cash payment equal to nine (9) months of Executive’s Salary.

    

    

    (ii)

      and further subject to Section 5(c), Executive will receive Company-paid group health, dental and vision coverage for Executive and any of Executive’s eligible dependents, as applicable (the “COBRA Severance”), following the Non-CIC Qualifying
      Termination until the earliest of:  (A) twelve (12) months following the date of the Non-CIC Qualifying Termination, (B) the date on which Executive and Executive’s eligible dependents (as applicable) become covered under similar plans, or (C) the
      expiration of Executive’s (and any of Executive’s eligible dependents, as applicable) eligibility for continuation coverage under COBRA.

    

    

    (iii)

    Bonus Severance.  A single, lump sum, cash payment equal to a pro-rated portion of Executive’s Target Bonus for the year in which the Non-CIC Qualifying Termination
      occurs, based on the number of days in such year for which Executive was employed by, or provided service to, the Company.

    

    

    
      
        

    

    
    

    

    (b)

    (iii)

    COBRA Severance.  Subject to Executive timely electing continuation coverage under COBRA and further subject to Section 5(c), Executive will receive COBRA Severance
      until the earliest of:  (A) twelve (12) months following the date of the Qualifying Termination, (B) the date on which Executive and Executive’s eligible dependents (as applicable) become covered under similar plans, or (C) the expiration of
      Executive’s (and any of Executive’s eligible dependents, as applicable) eligibility for continuation coverage under COBRA.

    

    

    (iv)

    Vesting Acceleration of Service-based Equity Awards.  Vesting acceleration of one hundred percent (100%) of any Equity Awards that are outstanding and unvested as of
      the date of the Qualifying Termination.  For the avoidance of doubt, in the event Executive’s Non-CIC Qualifying Termination occurs prior to a Change in Control, any then outstanding and unvested portion of Executive’s
        Awards will remain outstanding (and unvested) until the earlier of (x) three (3) months following the Non-CIC Qualifying Termination, or (y) a Change in Control that occurs within three (3) months following the Non-CIC Qualifying
      Termination, solely so that any benefits due on a CIC Qualifying Termination can be provided if the Non-CIC Qualifying Termination occurs during the Change in Control Period (provided that in no event will Executive’s stock option Equity Awards or
      similar Equity Awards remain outstanding beyond the Award’s maximum term to expiration).  If no Change in Control occurs within three (3) months following a Non-CIC Qualifying Termination, any unvested portion of

    (c)

    Termination Other Than a Qualifying Termination.  If the termination of Executive’s employment does not constitute a Qualifying Termination, then Executive will not be
      entitled to receive any severance or other benefits in connection with such termination except for those, if any, as may then be established under the Company’s then existing severance and benefits plans or programs.  Notwithstanding the foregoing,
      if the termination of Executive’s employment is due to Executive’s death or Disability, then subject to Executive (or Executive’s eligible dependents (as applicable)) timely electing continuation coverage under COBRA and further subject to Section
      5(c), Executive (and/or Executive’s eligible dependents (as applicable)) will receive COBRA Severance until the earliest of:  (i) twelve (12) months following the date of termination, (ii) the date on which Executive and Executive’s eligible
      dependents (as applicable) become covered under similar plans, or (iii) the expiration of Executive’s (and any of Executive’s eligible dependents, as applicable) eligibility for continuation coverage under COBRA.

    

    

    
      2

      
        

    

    

    

    (d)

    Non-duplication of Payment or Benefits.  For
        purposes of clarity, in the event of a Qualifying Termination that occurs during the period within three (3) months prior to a Change in Control, any severance payments and benefits to be provided to Executive under Section 3(b) will be reduced by
        any amounts that already were provided to Executive under Section 3(a).  Notwithstanding any provision of this Agreement to the contrary, if Executive is entitled to any cash severance, continued health coverage benefits, vesting acceleration of
        any Awards, or other severance or separation benefits similar to those provided under this Agreement, by operation of applicable law or under a plan, policy, contract, or arrangement sponsored by or to which the Company is a party other than this
        Agreement (“Other Benefits”), then the corresponding severance payments and benefits under this Agreement will be reduced by the amount of Other Benefits paid or
        provided to Executive.

    

    

    (e)

    Death of Executive.  In the event of Executive’s death before all payments or benefits Executive is entitled to receive under this Agreement have been provided, the
      unpaid amounts will be provided to Executive’s designated beneficiary, if living, or otherwise to Executive’s personal representative in accordance with the terms of this Agreement.

    

    

    4.

    Accrued Compensation.  On any termination of Executive’s employment with the Company, Executive will be entitled to receive all accrued but unpaid vacation, expense
      reimbursements, wages, and other benefits due to Executive under any Company-provided plans, policies, and arrangements.

    

    

    5.

    Conditions to Receipt of Severance.

    

    

    (a)

    Separation Agreement and Release of Claims.  Executive’s receipt of any severance payments or benefits upon a Qualifying Termination
        under Section 3 is subject to Executive signing and not revoking the Company’s then standard separation agreement and release of claims with the Company (the “Release”),
        which must become effective and irrevocable no later than the sixtieth (60th) day following the date of the
        Qualifying Termination (the “Release Deadline Date”).  If the Release does not become effective and irrevocable by the Release Deadline Date, Executive will forfeit
        any right to severance payments or benefits under Section 3.

    

    

    (b)

    Payment Timing.  Any lump sum cash severance payments under Section 3 relating to salary severance and any bonus severance will be
        provided to Executive on the first regularly scheduled payroll date of the Company following the date the Release becomes effective and irrevocable, subject to any delay required by Section 5(d) below.  Any Equity Awards that are restricted stock
        units, performance shares, performance units, and/or similar full value awards (“Full Value Awards”) that accelerate vesting under Section 3(b)(iv) will be settled,
        subject to any delay required by Section 5(d) below (or the terms of the Full Value Award agreement or other Company plan, policy, or arrangement governing the settlement timing of the Full Value Award to the extent such terms specifically require
        any such delay in order to comply with the requirements of Section 409A, as applicable (the “FVA Terms”)), (i) on a date within ten (10) days following the date the
        Release becomes effective and irrevocable, or (ii) if later, in the event of a Non-CIC Qualifying Termination that occurs prior to a Change in Control, on a date on or before the date of completion of the Change in Control.  Any Full Value Awards
        that accelerate vesting under Section 3(b)(iv) will be settled, subject to any delay required by Section 5(d) below (or any applicable FVA Terms), on a date on or before the date of completion of the Change in Control.

    

    

    (c)

    COBRA Severance Limitations.  If the Company determines in its sole discretion that it cannot provide the COBRA Severance without potentially violating, or being
      subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of such COBRA Severance, subject to any delay required by Section 5(d) below, the Company will provide to
      Executive a taxable monthly payment payable on the last day of a given month (except as provided by the immediately following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s
      group health coverage in effect on the date of the Qualifying Termination (which amount will be based on the premium rates applicable for the first month of COBRA Severance for Executive and any eligible dependents of Executive) (each, a “COBRA
        Replacement Payment”), which COBRA Replacement Payments will be made regardless of whether Executive elects COBRA continuation coverage and will end on the earlier of (i) the date upon which Executive obtains other employment, or (ii) the date
      the Company has paid an amount totaling the number of COBRA Replacement Payments equal to the number of months in the applicable COBRA Severance period set forth in clause (A) of Section 3(a)(ii) or Section 3(b)(iii), as applicable.  For the
      avoidance of doubt, the COBRA Replacement Payments may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to any applicable withholdings.  Notwithstanding anything to the contrary under this
      Agreement, if the Company determines in its sole discretion at any time that it cannot provide the COBRA Replacement Payments without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), Executive
      will not receive the COBRA Replacement Payments or any further COBRA Severance.

    

    

    
      3

      
        

    

    

    

    (d)

    Section 409A.  The Company intends that all payments and benefits provided under this Agreement or otherwise are exempt from, or comply
        with, the requirements of Section 409A so that none of the payments or benefits will be subject to the additional tax imposed under Section 409A, and any ambiguities and ambiguous terms in this Agreement will be interpreted in accordance with this
        intent.  No payments or benefits to be provided to Executive, if any, under this Agreement or otherwise, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A
        (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A.  To the
        extent required to be exempt from or comply with Section 409A, references to the termination of Executive’s employment or similar phrases used in this Agreement will mean Executive’s “separation from service” within the meaning of Section 409A.

    

    

    (i)

    Any payments or benefits paid or provided under this Agreement that satisfy the requirements of the “short-term deferral” rule under Treasury Regulations Section
      1.409A-1(b)(4), or that qualify as payments made as a result of an involuntary separation from service under Treasury Regulations Section 1.409A-1(b)(9)(iii) that is within the limit set forth thereunder, will not constitute Deferred Payments for
      purposes of this Section 5(d).

    

    

    (ii)

    Notwithstanding any provisions to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s
      separation from service (other than due to death), then any payments or benefits under this Agreement that constitute Deferred Payments payable within the first six (6) months after Executive’s separation from service instead will be payable on the
      date six (6) months and one (1) day after Executive’s separation from service; provided that in the event of Executive’s death within such six (6) month period, any payments delayed by this subsection (ii) will be paid to Executive in a lump sum as
      soon as administratively practicable after the date of Executive’s death.  To the extent that Executive is not a specified employee but Executive’s Qualifying Termination occurs at a time during the year whereby the Release Deadline Date will occur
      in the year immediately following the year in which the Qualifying Termination occurs, then any payments or benefits under this Agreement that constitute Deferred Payments that otherwise would be payable prior to the Release Deadline Date instead
      will be paid on the first regularly scheduled payroll date of the Company following the Release Deadline Date.

    

    

    (iii)

    The Company reserves the right to amend this Agreement as it considers necessary or advisable, in its sole discretion and without the consent of Executive or any other
      individual, to comply with any provision required to avoid the imposition of the additional tax imposed under Section 409A or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any
      additional tax.  Each payment, installment, and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Treasury Regulations Section 1.409A-2(b)(2).  In no event will Executive have any discretion to choose
      Executive’s taxable year in which any payments or benefits are provided under this Agreement.  In no event will the Company or any parent, subsidiary or other affiliate of the Company have any responsibility, liability or obligation to reimburse,
      indemnify or hold harmless Executive for any taxes, penalties or interest that may be imposed, or other costs that may be incurred, as a result of Section 409A.

    6.

    Limitation on Payments.

    

    

    (a)

    Reduction of Severance Benefits.  If any payment or benefit that Executive would receive from the Company or any other party whether in connection with the provisions
      in this Agreement or otherwise (the “Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise
        Tax”), then the Payments will be either delivered in full, or delivered as to such lesser extent that would result in no portion of the Payments being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the
      applicable federal, state and local income taxes and the Excise Tax, results in Executive’s receipt, on an after-tax basis, of the greatest amount of Payments, notwithstanding that all or some of the Payments may be subject to the Excise Tax.  If a
      reduction in Payments is made in accordance with the immediately preceding sentence, the reduction will occur, with respect to the Payments considered parachute payments within the meaning of Code Section 280G, in the following order:  (A) reduction
      of cash payments in reverse chronological order (that is, the cash payment owed on the latest date following the occurrence of the event triggering the Excise Tax will be the first cash payment to be reduced); (B) cancellation of equity awards that
      were granted “contingent on a change in ownership or control” within the meaning of Section 280G of the Code in the reverse order of date of grant of the equity awards (that is, the most recently granted equity awards will be cancelled first); (C)
      reduction of the accelerated vesting of equity awards in the reverse order of date of grant of the equity awards (that is, the vesting of the most recently granted equity awards will be cancelled first); and (D) reduction of employee benefits in
      reverse chronological order (that is, the benefit owed on the latest date following the occurrence of the event triggering the Excise Tax will be the first benefit to be reduced).  In no event will Executive have any discretion with respect to the
      ordering of Payment reductions.  Executive will be solely responsible for the payment of all personal tax liability that is incurred as a result of the payments and benefits received under this Agreement, and neither the Company nor any parent,
      subsidiary or other affiliate of the Company have any responsibility, liability or obligation to reimburse, indemnify or hold harmless Executive for any of those payments of personal tax liability.

    

    

    (b)

    Determination of Excise Tax Liability.  Unless the Company and Executive otherwise agree in writing, any determinations required under this Section 6 will be made in
      writing by a nationally recognized accounting or valuation firm (the “Firm”) selected by the Company, whose determinations will be conclusive and binding upon Executive and the Company for all purposes.  For purposes of making the calculations
      required by this Section 6, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.  The Company
      and Executive will furnish to the Firm such information and documents as the Firm reasonably may request in order to make determinations under this Section 6.  The Company will bear the costs and make all payments required to be made to the Firm for
      the Firm’s services that are rendered in connection with any calculations contemplated by this Section 6.  The Company will have no liability to Executive for the determinations of the Firm.

        policy or procedure that has been provided to Executive causing substantial injury to the Company, and/or (v) gross negligence or willful misconduct by Executive with respect to Executive’s performance of his or her assigned duties for the Company,
        following written notice of such negligence or misconduct by the Company and a period of fifteen (15) days to cure the same and Executive’s failure to cure during such time period.

    Change in Ownership of the Company.  A change in the ownership of the Company which occurs on the date that any one person, or
      more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the
      Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to already own more than fifty percent (50%) of the total voting power of the stock of the Company will not be
      considered a Change in Control; provided, further, that any change in the ownership of the stock of the Company as a result of a private financing of the Company that is approved by the Board also will not be considered a Change in Control.  Further,
      if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately
      prior to the change in ownership, direct or indirect beneficial ownership of fifty percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event shall not be considered a
      Change in Control under this subsection (i).  For this purpose, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities
      which own the Company, as the case may be, either directly or through one or more subsidiary corporations or other business entities; or

    

    

    (ii)

    Change in Effective Control of the Company.  If the Company has a class of securities registered pursuant to Section 12 of the U.S. Securities Exchange Act of 1934, as
      amended, a change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the
      members of the Board prior to the date of the appointment or election.  For purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same
      Person will not be considered a Change in Control; or

    

    

    (iii)

    Change in Ownership of a Substantial Portion of the Company’s Assets.  A change in the ownership of a substantial portion of the Company’s assets which occurs on the
      date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such Person or Persons) assets from the Company that have a total gross fair market value equal to or more than
      fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following will not constitute a
      change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a stockholder of
      the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (3) a
      Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is
      owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3).  For purposes of this subsection (iii), gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of,
      determined without regard to any liabilities associated with such assets.

    

    

    For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or
      similar business transaction with the Company.

    

    

    Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Section 409A.  Further and for
      the avoidance of doubt, a transaction will not constitute a Change in Control if: (x) its sole purpose is to change the jurisdiction of the Company’s incorporation, or (y) its sole purpose is to create a holding company that will be owned in
      substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.

    CHANGE IN CONTROL AND SEVERANCE AGREEMENT

    

    

    This Change in Control and Severance Agreement (the “Agreement”) is made by and between Kinnate Biopharma Inc., a Delaware corporation (the “Company”), and Richard Williams (“Executive”),
      effective as of the Effective Date, as defined in Section 7 below.

    

    

    This Agreement provides certain protections to Executive in connection with a change in control of the Company or in connection with the termination of Executive’s employment under the circumstances
      described in this Agreement.  Certain capitalized terms used in this Agreement are defined in Section 7 below.

    

    

    The Company and Executive agree as follows:

    

    

    1.

    Term of Agreement.  This Agreement will continue indefinitely until terminated by written consent of the parties hereto, or if earlier, upon the date that all of the
      obligations of the parties hereto with respect to this Agreement have been satisfied.

    

    

    2.

    At-Will Employment.  The Company and Executive acknowledge that Executive’s employment is and will continue to be at-will, as defined under applicable law.  No payments,
      benefits, or provisions under this Agreement will confer upon Executive any right to continue Executive’s employment with the Company, nor will they interfere with or limit in any way the right of the Company or Executive to terminate such
      relationship at any time, with or without cause, to the extent permitted by applicable laws.

    

    

    3.

    Severance Benefits.

    

    

    (a)

    Non-CIC Qualifying Termination.  In the event of a Non-CIC Qualifying Termination (as defined below) Executive will receive the following
        payments and benefits from the Company, subject to the requirements of this Agreement:

    

    

    (i)

    Salary Severance.  A single, lump sum, cash payment equal to nine (9) months of Executive’s Salary.

    

    

    (ii)

    COBRA Severance.  Subject to Executive timely electing continuation coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”)
      and further subject to Section 5(c), Executive will receive Company-paid group health, dental and vision coverage for Executive and any of Executive’s eligible dependents, as applicable (the “COBRA Severance”), following the Non-CIC Qualifying
      Termination until the earliest of:  nine (9) months following the date of the Non-CIC Qualifying Termination, (B) the date on which Executive and Executive’s eligible dependents (as applicable) become covered under similar plans, or (C) the
      expiration of Executive’s (and any of Executive’s eligible dependents, as applicable) eligibility for continuation coverage under COBRA.

    

    

    (iii)

    Vesting Acceleration of Service-based Equity Awards.  Vesting acceleration of any Awards that are outstanding and unvested as of the date of the Non-CIC Qualifying
      Termination that would have otherwise vested had Executive remained employed by the Company for nine (9) months following the Non-CIC Qualifying Termination.

    

    

    
      
        

    

    
    

    

    (b)

    CIC Qualifying Termination.  In the event of a CIC Qualifying Termination (as defined below), Executive will receive the following
        payments and benefits from the Company, subject to the requirements of this Agreement:

    

    

    (i)

    Salary Severance.  A single, lump sum, cash payment equal to twelve (12) or months of Executive’s Salary.

    

    

    (ii)

    Bonus Severance.  A single, lump sum, cash payment equal to the sum of (x) one hundred percent (100%) Executive’s Target Bonus, plus (y) a pro-rated portion of
      Executive’s Target Bonus for the year in which the Change in Control occurs, based on the number of days in such year for which Executive was employed by, or provided service to, the Company.

    

    

    (iii)

    COBRA Severance.  Subject to Executive timely electing continuation coverage under COBRA and further subject to Section 5(c), Executive will receive COBRA Severance
      until the earliest of:  (A) twelve (12) months following the date of the Qualifying Termination, (B) the date on which Executive and Executive’s eligible dependents (as applicable) become covered under similar plans, or (C) the expiration of
      Executive’s (and any of Executive’s eligible dependents, as applicable) eligibility for continuation coverage under COBRA.

    

    

    (iv)

    Vesting Acceleration of Service-based Equity Awards.  Vesting acceleration of one hundred percent (100%) of any Equity Awards that are outstanding and unvested as of
      the date of the Qualifying Termination.  For the avoidance of doubt, in the event Executive’s Non-CIC Qualifying Termination occurs prior to a Change in Control, any then outstanding and unvested portion of Executive’s
        Awards will remain outstanding (and unvested) until the earlier of (x) three (3) months following the Non-CIC Qualifying Termination, or (y) a Change in Control that occurs within three (3) months following the Non-CIC Qualifying
      Termination, solely so that any benefits due on a CIC Qualifying Termination can be provided if the Non-CIC Qualifying Termination occurs during the Change in Control Period (provided that in no event will Executive’s stock option Equity Awards or
      similar Equity Awards remain outstanding beyond the Award’s maximum term to expiration).  If no Change in Control occurs within three (3) months following a Non-CIC Qualifying Termination, any unvested portion of
        Executive’s Equity Awards automatically and permanently will be forfeited on the date three (3) months following the date of the Non-CIC Qualifying Termination without having vested.  In the event any of Executive’s Awards vest pursuant to Section
        3(a)(iii) above, the vesting acceleration rights provided in this Section 3(b)(iv) will be in addition to any vesting provided pursuant to Section 3(a)(iii) above.

    

    

    (c)

    Termination Other Than a Qualifying Termination.  If the termination of Executive’s employment does not constitute a Qualifying Termination, then Executive will not be
      entitled to receive any severance or other benefits in connection with such termination except for those, if any, as may then be established under the Company’s then existing severance and benefits plans or programs.

    

    

    
      2

      
        

    

    

    

    (d)

    Non-duplication of Payment or Benefits.  For
        purposes of clarity, in the event of a Qualifying Termination that occurs during the period within three (3) months prior to a Change in Control, any severance payments and benefits to be provided to Executive under Section 3(b) will be reduced by
        any amounts that already were provided to Executive under Section 3(a).  Notwithstanding any provision of this Agreement to the contrary, if Executive is entitled to any cash severance, continued health coverage benefits, vesting acceleration of
        any Awards, or other severance or separation benefits similar to those provided under this Agreement, by operation of applicable law or under a plan, policy, contract, or arrangement sponsored by or to which the Company is a party other than this
        Agreement (“Other Benefits”), then the corresponding severance payments and benefits under this Agreement will be reduced by the amount of Other Benefits paid or
        provided to Executive.

    

    

    (e)

    Death of Executive.  In the event of Executive’s death before all payments or benefits Executive is entitled to receive under this Agreement have been provided, the
      unpaid amounts will be provided to Executive’s designated beneficiary, if living, or otherwise to Executive’s personal representative in accordance with the terms of this Agreement.

    

    

    4.

    Accrued Compensation.  On any termination of Executive’s employment with the Company, Executive will be entitled to receive all accrued but unpaid vacation, expense
      reimbursements, wages, and other benefits due to Executive under any Company-provided plans, policies, and arrangements.

    

    

    5.

    Conditions to Receipt of Severance.

    

    

    (a)

    Separation Agreement and Release of Claims.  Executive’s receipt of any severance payments or benefits upon a Qualifying Termination
        under Section 3 is subject to Executive signing and not revoking the Company’s then standard separation agreement and release of claims with the Company (the “Release”),
        which must become effective and irrevocable no later than the sixtieth (60th) day following the date of the
        Qualifying Termination (the “Release Deadline Date”).  If the Release does not become effective and irrevocable by the Release Deadline Date, Executive will forfeit
        any right to severance payments or benefits under Section 3.

    

    

    (b)

    Payment Timing.  Any lump sum cash severance payments under Section 3 relating to salary severance and any bonus severance will be
        provided to Executive on the first regularly scheduled payroll date of the Company following the date the Release becomes effective and irrevocable, subject to any delay required by Section 5(d) below.  Any Equity Awards that are restricted stock
        units, performance shares, performance units, and/or similar full value awards (“Full Value Awards”) that accelerate vesting under Section 3(b)(iv) will be settled,
        subject to any delay required by Section 5(d) below (or the terms of the Full Value Award agreement or other Company plan, policy, or arrangement governing the settlement timing of the Full Value Award to the extent such terms specifically require
        any such delay in order to comply with the requirements of Section 409A, as applicable (the “FVA Terms”)), (i) on a date within ten (10) days following the date the
        Release becomes effective and irrevocable, or (ii) if later, in the event of a Non-CIC Qualifying Termination that occurs prior to a Change in Control, on a date on or before the date of completion of the Change in Control.  Any Full Value Awards
        that accelerate vesting under Section 3(b)(iv) will be settled, subject to any delay required by Section 5(d) below (or any applicable FVA Terms), on a date on or before the date of completion of the Change in Control.

    

    

    (c)

    COBRA Severance Limitations.  If the Company determines in its sole discretion that it cannot provide the COBRA Severance without potentially violating, or being
      subject to an excise tax under, applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then in lieu of such COBRA Severance, subject to any delay required by Section 5(d) below, the Company will provide to
      Executive a taxable monthly payment payable on the last day of a given month (except as provided by the immediately following sentence), in an amount equal to the monthly COBRA premium that Executive would be required to pay to continue Executive’s
      group health coverage in effect on the date of the Qualifying Termination (which amount will be based on the premium rates applicable for the first month of COBRA Severance for Executive and any eligible dependents of Executive) (each, a “COBRA
        Replacement Payment”), which COBRA Replacement Payments will be made regardless of whether Executive elects COBRA continuation coverage and will end on the earlier of (i) the date upon which Executive obtains other employment, or (ii) the date
      the Company has paid an amount totaling the number of COBRA Replacement Payments equal to the number of months in the applicable COBRA Severance period set forth in clause (A) of Section 3(a)(ii) or Section 3(b)(iii), as applicable.  For the
      avoidance of doubt, the COBRA Replacement Payments may be used for any purpose, including, but not limited to continuation coverage under COBRA, and will be subject to any applicable withholdings.  Notwithstanding anything to the contrary under this
      Agreement, if the Company determines in its sole discretion at any time that it cannot provide the COBRA Replacement Payments without violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), Executive
      will not receive the COBRA Replacement Payments or any further COBRA Severance.

    

    

    
      3

      
        

    

    

    

    (d)

    Section 409A.  The Company intends that all payments and benefits provided under this Agreement or otherwise are exempt from, or comply
        with, the requirements of Section 409A so that none of the payments or benefits will be subject to the additional tax imposed under Section 409A, and any ambiguities and ambiguous terms in this Agreement will be interpreted in accordance with this
        intent.  No payments or benefits to be provided to Executive, if any, under this Agreement or otherwise, when considered together with any other severance payments or separation benefits that are considered deferred compensation under Section 409A
        (together, the “Deferred Payments”) will be paid or otherwise provided until Executive has a “separation from service” within the meaning of Section 409A.  To the
        extent required to be exempt from or comply with Section 409A, references to the termination of Executive’s employment or similar phrases used in this Agreement will mean Executive’s “separation from service” within the meaning of Section 409A.

    

    

    (i)

    Any payments or benefits paid or provided under this Agreement that satisfy the requirements of the “short-term deferral” rule under Treasury Regulations Section
      1.409A-1(b)(4), or that qualify as payments made as a result of an involuntary separation from service under Treasury Regulations Section 1.409A-1(b)(9)(iii) that is within the limit set forth thereunder, will not constitute Deferred Payments for
      purposes of this Section 5(d).

    

    

    (ii)

    Notwithstanding any provisions to the contrary in this Agreement, if Executive is a “specified employee” within the meaning of Section 409A at the time of Executive’s
      separation from service (other than due to death), then any payments or benefits under this Agreement that constitute Deferred Payments payable within the first six (6) months after Executive’s separation from service instead will be payable on the
      date six (6) months and one (1) day after Executive’s separation from service; provided that in the event of Executive’s death within such six (6) month period, any payments delayed by this subsection (ii) will be paid to Executive in a lump sum as
      soon as administratively practicable after the date of Executive’s death.  To the extent that Executive is not a specified employee but Executive’s Qualifying Termination occurs at a time during the year whereby the Release Deadline Date will occur
      in the year immediately following the year in which the Qualifying Termination occurs, then any payments or benefits under this Agreement that constitute Deferred Payments that otherwise would be payable prior to the Release Deadline Date instead
      will be paid on the first regularly scheduled payroll date of the Company following the Release Deadline Date.

    

    

    (iii)

    The Company reserves the right to amend this Agreement as it considers necessary or advisable, in its sole discretion and without the consent of Executive or any other
      individual, to comply with any provision required to avoid the imposition of the additional tax imposed under Section 409A or to otherwise avoid income recognition under Section 409A prior to the actual payment of any benefits or imposition of any
      additional tax.  Each payment, installment, and benefit payable under this Agreement is intended to constitute a separate payment for purposes of Treasury Regulations Section 1.409A-2(b)(2).  In no event will Executive have any discretion to choose
      Executive’s taxable year in which any payments or benefits are provided under this Agreement.  In no event will the Company or any parent, subsidiary or other affiliate of the Company have any responsibility, liability or obligation to reimburse,
      indemnify or hold harmless Executive for any taxes, penalties or interest that may be imposed, or other costs that may be incurred, as a result of Section 409A.

    6.

    Limitation on Payments.

    

    

    (a)

    Reduction of Severance Benefits.  If any payment or benefit that Executive would receive from the Company or any other party whether in connection with the provisions
      in this Agreement or otherwise (the “Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise
        Tax”), then the Payments will be either delivered in full, or delivered as to such lesser extent that would result in no portion of the Payments being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the
      applicable federal, state and local income taxes and the Excise Tax, results in Executive’s receipt, on an after-tax basis, of the greatest amount of Payments, notwithstanding that all or some of the Payments may be subject to the Excise Tax.  If a
      reduction in Payments is made in accordance with the immediately preceding sentence, the reduction will occur, with respect to the Payments considered parachute payments within the meaning of Code Section 280G, in the following order:  (A) reduction
      of cash payments in reverse chronological order (that is, the cash payment owed on the latest date following the occurrence of the event triggering the Excise Tax will be the first cash payment to be reduced); (B) cancellation of equity awards that
      were granted “contingent on a change in ownership or control” within the meaning of Section 280G of the Code in the reverse order of date of grant of the equity awards (that is, the most recently granted equity awards will be cancelled first); (C)
      reduction of the accelerated vesting of equity awards in the reverse order of date of grant of the equity awards (that is, the vesting of the most recently granted equity awards will be cancelled first); and (D) reduction of employee benefits in
      reverse chronological order (that is, the benefit owed on the latest date following the occurrence of the event triggering the Excise Tax will be the first benefit to be reduced).  In no event will Executive have any discretion with respect to the
      ordering of Payment reductions.  Executive will be solely responsible for the payment of all personal tax liability that is incurred as a result of the payments and benefits received under this Agreement, and neither the Company nor any parent,
      subsidiary or other affiliate of the Company have any responsibility, liability or obligation to reimburse, indemnify or hold harmless Executive for any of those payments of personal tax liability.

    

    

    (b)

    Determination of Excise Tax Liability.  Unless the Company and Executive otherwise agree in writing, any determinations required under this Section 6 will be made in
      writing by a nationally recognized accounting or valuation firm (the “Firm”) selected by the Company, whose determinations will be conclusive and binding upon Executive and the Company for all purposes.  For purposes of making the calculations
      required by this Section 6, the Firm may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.  The Company
      and Executive will furnish to the Firm such information and documents as the Firm reasonably may request in order to make determinations under this Section 6.  The Company will bear the costs and make all payments required to be made to the Firm for
      the Firm’s services that are rendered in connection with any calculations contemplated by this Section 6.  The Company will have no liability to Executive for the determinations of the Firm.

    

    

    7.

    Definitions.  The following terms referred to in this Agreement will have the following meanings:

    

    

    (a)

    “Award” means any stock option or other equity award covering shares of Company common stock granted to Executive.

    

    

    (b)

    “Board” means the Company’s Board of Directors.

    (d)

    “Change in Control” means the first occurrence of any of the following events on or after the Effective Date:

    

    

    (i)

    Change in Ownership of the Company.  A change in the ownership of the Company which occurs on the date that any one person, or
      more than one person acting as a group (“Person”), acquires ownership of the stock of the Company that, together with the stock held by such Person, constitutes more than fifty percent (50%) of the total voting power of the stock of the
      Company; provided, however, that for purposes of this subsection, the acquisition of additional stock by any one Person, who is considered to already own more than fifty percent (50%) of the total voting power of the stock of the Company will not be
      considered a Change in Control; provided, further, that any change in the ownership of the stock of the Company as a result of a private financing of the Company that is approved by the Board also will not be considered a Change in Control.  Further,
      if the stockholders of the Company immediately before such change in ownership continue to retain immediately after the change in ownership, in substantially the same proportions as their ownership of shares of the Company’s voting stock immediately
      prior to the change in ownership, direct or indirect beneficial ownership of fifty percent (50%) or more of the total voting power of the stock of the Company or of the ultimate parent entity of the Company, such event shall not be considered a
      Change in Control under this subsection (i).  For this purpose, indirect beneficial ownership shall include, without limitation, an interest resulting from ownership of the voting securities of one or more corporations or other business entities
      which own the Company, as the case may be, either directly or through one or more subsidiary corporations or other business entities; or

    

    

    (ii)

    Change in Effective Control of the Company.  If the Company has a class of securities registered pursuant to Section 12 of the U.S. Securities Exchange Act of 1934, as
      amended, a change in the effective control of the Company which occurs on the date that a majority of members of the Board is replaced during any twelve (12) month period by Directors whose appointment or election is not endorsed by a majority of the
      members of the Board prior to the date of the appointment or election.  For purposes of this subsection (ii), if any Person is considered to be in effective control of the Company, the acquisition of additional control of the Company by the same
      Person will not be considered a Change in Control; or

    

    

    (iii)

    Change in Ownership of a Substantial Portion of the Company’s Assets.  A change in the ownership of a substantial portion of the Company’s assets which occurs on the
      date that any Person acquires (or has acquired during the twelve (12) month period ending on the date of the most recent acquisition by such Person or Persons) assets from the Company that have a total gross fair market value equal to or more than
      fifty percent (50%) of the total gross fair market value of all of the assets of the Company immediately prior to such acquisition or acquisitions; provided, however, that for purposes of this subsection (iii), the following will not constitute a
      change in the ownership of a substantial portion of the Company’s assets: (A) a transfer to an entity that is controlled by the Company’s stockholders immediately after the transfer, or (B) a transfer of assets by the Company to: (1) a stockholder of
      the Company (immediately before the asset transfer) in exchange for or with respect to the Company’s stock, (2) an entity, fifty percent (50%) or more of the total value or voting power of which is owned, directly or indirectly, by the Company, (3) a
      Person, that owns, directly or indirectly, fifty percent (50%) or more of the total value or voting power of all the outstanding stock of the Company, or (4) an entity, at least fifty percent (50%) of the total value or voting power of which is
      owned, directly or indirectly, by a Person described in this subsection (iii)(B)(3).  For purposes of this subsection (iii), gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of,
      determined without regard to any liabilities associated with such assets.

    

    

    For purposes of this definition, persons will be considered to be acting as a group if they are owners of a corporation that enters into a merger, consolidation, purchase or acquisition of stock, or
      similar business transaction with the Company.

    

    

    Notwithstanding the foregoing, a transaction will not be deemed a Change in Control unless the transaction qualifies as a change in control event within the meaning of Section 409A.  Further and for
      the avoidance of doubt, a transaction will not constitute a Change in Control if: (x) its sole purpose is to change the jurisdiction of the Company’s incorporation, or (y) its sole purpose is to create a holding company that will be owned in
      substantially the same proportions by the persons who held the Company’s securities immediately before such transaction.
