  KARYOPHARM THERAPEUTICS INC.

  Nonstatutory Stock Option Agreement

  Granted Under 2022 Inducement Stock Incentive Plan

  Incorporated Terms and Conditions

  1.Grant of Option.


  This agreement evidences the grant by the Company, on the grant date (the “Grant Date”) set forth in the Notice of Grant that forms part of this agreement (the “Notice of Grant”) to the Participant of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s 2022 Inducement Stock Incentive Plan (the “Plan”), the number of Shares set forth in the Notice of Grant of common stock, $0.0001 par value per share, of the Company (“Common Stock”) at the exercise price per Share set forth in the Notice of Grant.  Unless earlier terminated, this option shall expire at 5:00 p.m., Eastern time, on the Final Exercise Date set forth in the Notice of Grant (the “Final Exercise Date”).

  The option evidenced by this agreement was granted to the Participant pursuant to the inducement grant exception under Nasdaq Stock Market Rule 5635(c)(4) as an inducement that is material to the Participant’s entering into employment with the Company. 

  It is intended that the option evidenced by this agreement shall not be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”).  Except as otherwise indicated by the context, the term “Participant”, as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms.

  2.Vesting Schedule.


  This option will become exercisable (“vest”) in accordance with the vesting schedule set forth on the cover page of this agreement (the “Vesting Schedule”).  Any fractional shares resulting from the application of any percentages used in the Vesting Table shall be rounded down to the nearest whole number of shares of Common Stock (except for the last vesting tranche).  

  Notwithstanding the foregoing, to the extent that the Participant is a party to an employment agreement or other agreement with the Company that provides vesting terms that differ from the Vesting Schedule, the terms set forth in such employment agreement or other agreement shall prevail.

  The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan.

   

  3.Exercise of Option.


  - 2 -

   

  

   

  a.Form of Exercise. Each election to exercise this option shall be in writing in the form of the Stock Option Exercise Notice attached hereto as Exhibit A, signed by the Participant, and received by the Company at its principal office, accompanied by this agreement, or in such other form, which may be electronic, as determined by the Company, together with payment in full of the exercise price and any applicable tax withholding in the manner provided in the Plan. The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than ten whole shares.


  b.Continuous Relationship with the Company Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant to, the Company or any other entity the service providers of which are eligible to receive option grants under the Plan (an “Eligible Participant”).


  c.Termination of Relationship with the Company. If the Participant ceases to be an Eligible Participant for any reason, then, except as provided in paragraphs (d) and (e) below, the right to exercise this option shall terminate three months after such cessation (but in no event after the Final Exercise Date), provided that this option shall be exercisable only to the extent that the Participant was entitled to exercise this option on the date of such cessation. Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the non-competition or confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon written notice to the Participant from the Company describing such violation.


  d.Exercise Period Upon Death or Disability.  If the Participant dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below, this option shall be exercisable, within the period of one year following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date.


  e.Termination for Cause.  If, prior to the Final Exercise Date, the Participant’s employment or other relationship with the Company is terminated by the Company for Cause (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such termination of employment or other relationship.  “Cause” shall mean, in the good faith determination of the Company, the Participant has: (i) committed gross negligence or willful malfeasance in the performance of the Participant’s work or duties; (ii) committed a breach of fiduciary duty or a breach of any non-competition, non-solicitation or confidentiality obligations to the Company; (iii) failed to follow the proper directions of the Participant’s direct or indirect supervisor after written notice of such failure; (iv) been convicted of, or pleaded “guilty” or “no contest” to, any misdemeanor relating to the affairs of the Company or any felony; (v) disregarded the material rules or material policies of the Company which has not been

  cured within 15 days after notice thereof from the Company; or (vi) engaged in intentional acts that have generated material adverse publicity toward or about the Company.


  4.Withholding.  


  No Shares will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company, or makes provision satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of this option.

   

  5.	Reporting.

  The Participant acknowledges and agrees to comply with all necessary reporting

  obligations in the Participant’s jurisdiction in relation to all taxes, social security contributions and any other similar charges which arise in relation to this option.

   

  6.   Transfer Restrictions.

  	This option may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant.  

   

  7.	Participant’s Acknowledgement of Clawback.

  The Participant acknowledges that in accepting this award, the Participant agrees to be bound by any clawback policy that the Company has in place or may adopt in the future.

  8.       Provisions of the Plan.

  	This option is subject to the provisions of the Plan (including the provisions relating to amendments to the Plan), a copy of which is furnished to the Participant with this option.
