(a)As Chief Medical Officer, you will perform  such duties as are customarily  provided by a Chief Medical Officer of a similarly situated company in the United States and shall have such  other  responsibilities   and  duties  as  may  be  from  time  to  time  directed  by  the Company.    You  shall  report  directly  to the  Company's  President  &  Chief Executive Officer.

Any  such outside  business activities  that  you may  wish  to  pursue  during  the term  of your  employment  with  the Company  shall  require  the  prior  written  consent  of the  Company's  Chief Executive Officer. Notwithstanding  the  foregoing, you  may  continue  to  provide  the  services  set forth on  Exhibit  A, attached  hereto  and  made  a part  hereof,  in  the  capacity  set forth thereon.
(c)Your duties shall be performed primarily at the Company's corporate  offices, which are currently  located  at  1300  S.  El Camino  Real, Suite 300, San Mateo CA 94402, or such other place as the parties may agree.
2.Start Date.   Your employment shall commence on November 18, 2019, or such other date as may be agreed to by you and the Company.
3.Compensation.
(a)Base Salary.  You shall  receive an annual base salary equal to Three Hundred Eighty Seven  Thousand  Five  Hundred  Dollars  (US$387,500),   which  shall  be  payable  in accordance with the Company's payroll practices.

(c)Withholding.  Except  as  expressly  stated  otherwise,  the  Company  shall  withhold  all applicable  federal,  state and local  taxes and  social  security  and such other amounts  as may be required by law from all amounts payable under this Section 3.
4.Equity Awards.
(a)Subject to the approval of the Board of Directors  of the Company  (the "Board"),  or an authorized  committee  thereof,  you  shall  be  granted  a  stock  option  (the  "Option")  to purchase 360,000 shares of the Company's common stock (the "Option Shares") pursuant to  the  Company's  2017  Equity  Incentive   Plan  (the  "Plan").     Such  grant  shall  be evidenced  by an option agreement  (the "Option  Agreement")  to be entered  into by and between you and the Company.   In  the event of a conflict  between this Agreement  and the  Option  Agreement, the terms  of the Option  Agreement  shall control.  The exercise price per Option Share will be equal to the fair market value per share of the Company's Common Stock as of the date that such Option is granted by the Board.  The Option shall have a 10-year term and shall vest and become exercisable  as follows:  (i) 25% upon the first anniversary  date of your Start Date (the "Initial  Vesting  Date");  and thereafter  (ii) the remaining unvested Options Shares shall vest in 36 substantially equal monthly installments as of the last calendar day of each month following the Initial Vesting Date.
(b)All Options shall be immediately exercisable with respect to one hundred percent (100%) of the Option Shares in exchange for restricted shares of Common Stock of the Company (the "Restricted  Shares"); provided, however, that the Restricted  Shares will be subject to a  repurchase  right (the  "Repurchase   Right")  in  favor of the  Company  that  lapses  in accordance  with the schedule  described  above.   Upon termination  of your employment, the  Company  may exercise  its Repurchase  Right with  respect  to  any  or all  Restricted Shares for which the Repurchase  Right has lapsed  at a price equal to the exercise price per Option Share.
(c)All Options  and Option  Shares shall become one hundred  percent  ( 100%)  vested  upon the consummation  of a Change of Control (as defined in the Plan) that occurs at any time prior to the date that the Company becomes a publicly reporting company.   Thereafter,  in the event that your employment is terminated without Cause or you terminate your employment  for Good Reason, in either case at any time beginning on the date that is 90 days prior to the effective date of a Change of Control (as defined in the Plan) and ending on the  date  that  is  12 months  following the  Change  of Control,  then  (i) all  unvested Restricted Shares and/or Option Shares shall immediately vest in full, and (ii) all Options will remain  exercisable for a period  of 90 calendar days following the date of such termination, after which time the Option  shall expire;  provided, however, that no such Option shall be exercisable after the expiration of its  maximum term. In order to give effect to the foregoing provision, notwithstanding anything to the contrary set forth in any agreement governing an equity award regarding immediate forfeiture of unvested shares upon termination  of service or  the  duration  of post-termination  of service  exercise periods, following any termination of your employment, none of your equity incentive awards shall terminate with respect to any vested or unvested portion subject to such equity award before 90 days following such termination.

(c)The  failure  of either  party to  insist upon the  strict  performance  of any  of the  terms, conditions  and  provisions  of this  agreement  shall  not  be  construed  as  a  waiver  or relinquishment  of future compliance therewith, and such terms, conditions and provisions shall  remain  in  full  force  and  effect.

No representation, promise  or  inducement  has  been  made  by  either  party  that  is  not  embodied  in  this agreement,  and neither party shall be bound by or liable for any alleged representation, promise or inducement not so set forth.

(c)satisfying the requirements of the Immigration Control and Reform Act, which may be accomplished by showing your proof of right to work in the U.S. within three days of commencing employment (see http://www.uscis.gov/i-9 for a list of acceptable proof, such as (i) an original drivers license and social security card, or (ii) a passport).
(d)Notwithstanding the foregoing, this offer may be withdrawn by the Company at any time prior to its execution by the Company.

Accordingly, you may terminate your employment with the Company at any time and for any reason whatsoever, without or without advance notice, simply by notifying the Company in writing. Similarly, the Company may terminate your employment at any time and for any reason whatsoever, with or without cause or advance notice. This at-will relationship cannot be changed except in a writing signed by a duly authorized office of the Company and you.

(ii)continue to pay your Base Salary at the rate in effect at the time of termination (without regard to any reduction in Base Salary that served as the basis for a 
4

(iii)to the extent permitted by applicable healthcare laws and provided that you make a timely election to continue coverage, the Company shall pay directly to the insurance provider the premium for COBRA continuation coverage for you and your dependents (if any), less the amount payable by an active employee for such coverage, during the Severance Period or until you obtain new employment, whichever comes first (the benefits described in this Section 11(a)(iii)shall be referred to as the “Continued Benefits”). Notwithstanding the foregoing, in the event applicable healthcare laws do not permit continuation of coverage, then the Company shall reimburse you for the costs of obtaining coverage in an amount not to exceed the coverage amounts paid or payable by you immediately prior to the date of termination; and
(iv)the vesting applicable to all Equity Awards shall cease immediately and you shall have a period of 90 days to exercise any vested Equity Awards, after which time all Equity Awards shall expire; provided, however, that no such Equity Award shall be exercisable after the expiration of its maximum term pursuant to the terms thereof.

(d)This Section 11 sets forth the only obligations of the Company with respect to the termination of your employment with the Company, and you acknowledge that, upon the termination of your employment, you shall not be entitled to any payments or benefits which are not explicitly provided in this Section 11. Further, notwithstanding anything to the contrary contained herein, the Company shall have no obligation to pay, and you shall have no right to receive, any compensation, benefits or other consideration provided for in this Section 11 (other than any accrued but unpaid Base Salary through the date of termination and any reimbursement of unreimbursed expenses incurred prior to the date of termination, and your option to elect COBRA benefits provided that you pay the premium) (the “Severance Payments”) unless you execute an agreement substantially in the form attached hereto as Exhibit C (the “Release Agreement”) releasing the Company from any and all liability in connection with the your employment or the termination thereof that becomes effective no later than 60 days following your termination (the “Release Deadline”). Except as required by Section 12, the Severance Payments will commence on the first payroll period following the Release Agreement becoming effective; provided, that (i) if the Severance Payments (or any portion thereof) constitute “deferred compensation” within the meaning of Section 409A (as defined in Section 12) and (ii) the period commencing on the date of termination and ending on the Release Deadline spans two calendar years, then the Severance Payments (or such portion thereof that constitute “deferred compensation”) will commence on the later of the Release Agreement becoming effective and the first payroll date of the Company in the second calendar year. Any portion of the Severance Payments that is delayed due to the application of the preceding sentence shall be made on the date that the Severance Payments commence.
(e)Effective as of the date of any termination of your employment, unless otherwise agreed to by you and the Company, upon termination of your employment hereunder for any reason, you shall be deemed to have resigned from all offices held at the Company or any subsidiary or other affiliate of the Company at the date of such termination, including without limitation the position of Chief Business Officer.
(f)The Company shall withhold all applicable federal, state and local taxes and social security and such other amounts as may be required by law from all amounts payable to you under this Section 11.
(g)The provisions of this Section 11 shall survive any termination of this Employment Letter.
(h)For purposes of this Employment Letter “Good Reason” shall mean (A) any material diminution by the Company of your title, duties, authority or Base Salary; or (B) a material breach by the Company of any of the provisions contained in this Employment Letter, which, if capable of being cured, is not cured by the Company within 30 days after written notice thereof by you to the Company; or (C) relocation of your principal place of employment more than 50 miles without your consent. Notwithstanding the foregoing, should you wish to terminate your employment for Good Reason, you must provide the Company with written notice of such Good Reason within 30 days of the occurrence of the condition alleged to have caused such Good Reason and reasonably cooperate with the Company in remedying the condition causing Good Reason for a period of 30 days (the “Cure Period”). If, following the Cure Period, the condition 
6

causing Good Reason remains uncured, a termination of employment by you for Good Reason shall be effective on the day following the expiration of such Cure Period.
12.Section 409A.  Notwithstanding anything to the contrary set forth herein, any payments and benefits provided under this Employment Letter that constitute “deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations and other guidance thereunder and any state law of similar effect (collectively, “Section 409A”) and that are payable in connection with your termination of employment shall not commence unless and until you have also incurred a “separation from service” within the meaning of Section 409A, unless the Company reasonably determines that such amounts may be provided to you without causing you to incur the additional 20% tax under Section 409A. If you are, upon a separation from service, a “specified employee” within the meaning of Section 409A, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A, the payment of any deferred compensation shall not commence until the earlier to occur of: (i) the date that is six months and one day after your separation from service, or (ii) the date of your death. Any payments that are delayed due to the application of the preceding sentence shall be made on the date that payments commence. For purposes of Section 409A, the right to a series of installment payments under this Employment Letter shall be treated as a right to a series of separate payments.
13.No Reliance by You on Promise or Representation Not in this Agreement.  In accepting employment with the Company and signing this Employment Letter, you agree that you are not relying on any representation, promise or inducement that has been made by the Company or any representative on its behalf that is not explicitly stated in this Employment Letter.

14.Governing Law; Arbitration.  The terms of this offer letter shall be governed by, and construed and interpreted in accordance with, the laws of the State of California without regard to principles of conflict of laws.

The Federal Arbitration Act shall govern the interpretation, enforcement and all proceedings pursuant to the Mutual Agreement to Arbitrate Claims. To the extent that the Federal Arbitration Act is inapplicable, the terms of the Mutual Agreement to Arbitrate Claims shall be construed in accordance with California law.
15.Miscellaneous.
