Dear Mr. Mahmood:

I am pleased to offer you a position with Nkarta, Inc. (the "Company"), as Senior Vice President, Corporate Development, reporting to the Chief Executive Officer of the Company.  If you decide to join us, your employment would commence on a mutually agreeable starting date (the "Effective Date"). You will receive an annual base salary of $250,000 (the "Base Salary"), which will be paid periodically in accordance with the Company's normal payroll practices and be subject to the usual, required withholdings. Your Base Salary will be subject to review and adjustments will be made based upon the Company' s normal performance review practices.

As of the Effective Date, you will be eligible to receive an annual bonus of up to 25% of your Base Salary then in effect upon achievement of performance objectives to be determined by the Board in its sole discretion (the "Target Bonus"). Your Target Bonus shall be pro-rated for 2018. The Target Bonus, or any portion thereof, will be paid, less applicable withholdings, as soon as practicable after the Board of Directors of the Company (the "Board'') determines that the Target Bonus has been earned, but in no event shall the Target Bonus be paid after the later of (i) the fifteenth (15th) day of the third (3rd) month following the close of the Company's fiscal year (which currently is December 31^st) in which the Target Bonus is earned or (ii) March 15 following the calendar year in which the Target Bonus is earned. Any bonuses will be subject to your continued employment with the Company through the date the bonus is earned.

If you decide to join the Company, the Company shall recommend that the Board grant to you an option to purchase, pursuant to an option agreement subject to an early exercise provision, 94,000  shares of Common Stock, par value $0.0001 per share, of the Company (the "Common Stock") at a price per share equal to the fair market value per share of the Common Stock on the date of grant, as determined by the Board (the "Option Grant"). The Option Grant is intended to represent approximately 0.7% of the Fully Diluted Shares (as defined below) currently outstanding. For the purposes of this offer letter, ''Fully Diluted Shares" shall be calculated by adding (x) the number of outstanding shares of capital stock of the Company, plus (y) the number of shares of Company common stock subject  to  issuance  under outstanding options or warrants, plus (z) the number of unallocated shares of Company common stock reserved for issuance pursuant to the Company's stock option plans, in each case, as of the close of the business day preceding the date of determination. Subject to the vesting acceleration terms described in this offer letter, twenty-five percent (25%) of the Option Grant shall vest (or be released from the Company's repurchase right, as applicable) one year from the Effective Date, subject to your continuing employment with the Company, and none of the Option Grant shall vest (or be released from the Company' s repurchase right, as applicable) before such date. The remaining shares subject to the Option Grant shall vest (or be released from the Company's repurchase right, as applicable) monthly over the next thirty-six (36) months in equal monthly amounts subject to your continuing employment with the Company. Any shares acquired upon exercise of the Option

Grant, will be subject to the terms and conditions of the Company's 2015 Equity Incentive Plan and option agreement to be entered into between you and the Company.

If you accept this offer of employment, from and after the Effective Date, you will be entitled to participate in any employee benefit plans hereafter maintained by the Company of general applicability to other senior executives of the Company, including, without limitation, any group medical, dental, vision, disability, life insurance plans maintained by the Company, subject to the terms and conditions of the applicable plans.
