NON-STATUTORY
STOCK OPTION AGREEMENT


 


1. Grant
of Option. Effective March 1, 2013 (“Date of Grant”), FELICITEX THERAPEUTICS, INC., a Delaware corporation (the “Corporation”),
hereby grants to Yuriy Gankin (the “Optionee”) an option, pursuant to the Corporation’s 2012 Stock Option and Restricted
Stock Plan (the “Plan”), to purchase an aggregate of Sixty Eight Thousand Forty One (68,041) shares of the Corporation’s
$0.0001 par value common stock (“Common Stock”) at a price of Two (0.02¢) cents per share, purchasable as set forth
in and subject to the terms and conditions of this option and the Plan. Except where the context otherwise requires, the term “Corporation”
shall include the all present and future subsidiaries of the Corporation as defined in Sections 424(e) and 424(f) of the Internal Revenue
Code of 1986, as amended or replaced from time to time (the “Code”).


 


2. Non-Statutory
Stock Option. This option is not intended to qualify as an incentive stock option within the meaning of Section 422 of the Code.


 


 3. Exercise of option and Provisions for Termination.




 


(a) Vesting
Schedule. Except as otherwise provided in this Agreement, this option may be exercised prior to the tenth (10th) anniversary of the
Date of Grant (hereinafter the “Expiration Date”). Effective as of the Date of Grant, all of the shares covered by this Option
Agreement shall be deemed fully vested and not subject to repurchase by the Corporation.


 


The
right of exercise shall be cumulative so that if the option is not exercised to the maximum extent permissible during any exercise period,
it shall be exercisable, in whole or in part, with respect to all shares not so purchased at any time prior to the Expiration Date or
the earlier termination of this option. This option may not be exercised at any time on or after the Expiration Date, except as otherwise
provided in Section 3(e) below.


 


(b) Exercise
Procedure. Subject to the conditions set forth in this Agreement, this option shall be exercised by the Optionee’s delivery
of a written notice of exercise in the form attached hereto and marked as Exhibit 1 to the Treasurer of the Corporation, specifying
the number of shares to be purchased and the purchase price to be paid therefor and accompanied by payment in full in accordance with
Section 4. Such exercise shall be effective upon receipt by the Treasurer of the Corporation of such written notice together with the
required payment. The Optionee 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 (10) whole shares.


 


(c) Continuous
Relationship with the Corporation. Except as otherwise provided in this Section 3, this option may not be exercised unless the Optionee,
at the time it exercises this option, is, and has been at all times since the date of grant of this option, an employee, officer or director
of, or consultant or advisor to, the Corporation or any subsidiary (an “Eligible Optionee”).


 






     


    	



    

 





(d) Exercise
Period Upon Termination of Relationship with the Corporation. If the Optionee ceases to be an Eligible Optionee for any reason, then,
except as provided in paragraphs (e) and (f) below, the right to exercise this option shall terminate ten (10) years after such cessation
(but in no event after the Expiration Date), provided that this option shall be exercisable only to the extent that the Optionee
was entitled to exercise this option on the date of such cessation. The Corporation’s obligation to deliver shares upon the exercise
of this option shall be subject to the satisfaction of all applicable federal, state and local income and employment tax withholding
requirements. Notwithstanding the foregoing, if the Optionee, prior to the Expiration Date, materially violates the noncompetition or
confidentiality provisions of any employment contract, confidentiality and nondisclosure agreement or other agreement between the Optionee
and the Corporation or any subsidiary, the right to exercise this option shall terminate immediately upon written notice to the Optionee
from the Corporation or any subsidiary describing such violation.


 


(e) Exercise
Period Upon Death or Disability. If the Optionee dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior
to the Expiration Date while it is an Eligible Optionee, or if the Optionee dies within three (3) months after the Optionee ceases to
be an Eligible Optionee (other than as the result of a termination of such relationship by the Corporation or any subsidiary for “cause”
as specified in paragraph (f) below), this option shall be exercisable, within the period of one (1) year following the date of death
or disability of the Optionee (whether or not such exercise occurs before the Expiration Date), by the Optionee or by the person to whom
this option is transferred by will or the laws of descent and distribution, provided that this option shall be exercisable only to the
extent that this option was exercisable by the Optionee on the date of his death or disability. Except as otherwise indicated by the
context, the term “Optionee,” as used in this option, shall be deemed to include the estate of the Optionee or any person
who acquires the right to exercise this option by bequest or inheritance or otherwise by reason of the death of the Optionee.


 


(f) Discharge
for Cause. If the Optionee, prior to the Expiration Date, is discharged by the Corporation or any subsidiary for “cause”
(as defined below), the right to exercise this option shall terminate immediately upon such cessation of employment. “Cause”
shall mean willful misconduct by the Optionee or willful failure to perform his responsibilities in the best interests of the Corporation
or any subsidiary (including, without limitation, breach by the Optionee of any provision of any employment, consulting, advisory, nondisclosure,
non- competition or other similar agreement between the Optionee and the Corporation or any subsidiary), as determined by the Corporation
or any subsidiary, which determination shall be conclusive. The Optionee shall be considered to have been discharged for “cause”
if the Corporation or any subsidiary determines, within thirty (30) days after the Optionee’s resignation, that discharge for cause
was warranted.

 4. Payment of Purchase Price.




 


(a) Method
of Payment. Payment of the purchase price for shares purchased upon exercise of this option shall be made: (i) by delivery to
the Corporation of cash or a check to the order of the Corporation in an amount equal to the purchase price of such shares, (ii)
subject to the consent of the Corporation, by delivery to the Corporation of shares of Common Stock of the Corporation then owned by
the Optionee having a fair market value equal in amount to the purchase price of such shares, (iii) by any other means which the
Administrator (as that term is defined in the Plan) determines are consistent with the purpose of the Plan and with applicable laws
and regulations (including, without limitation, the provisions of Rule 16b-3 under the Securities Exchange Act of 1934 and
Regulation T promulgated by the Federal Reserve Board), or (iv) by any combination of such methods of payment.


 


(b) Valuation
of Shares or Other Non-Cash Consideration Tendered in Payment of Purchase Price. For the purposes hereof, the fair market value of
any share of the Corporation’s Common Stock or other non-cash consideration which may be delivered to the Corporation in exercise
of this option shall be determined in good faith by the Administrator.


 


(c) Delivery
of Shares Tendered in Payment of Purchase Price. If the Optionee exercises this option by delivery of shares of Common Stock of the
Corporation, the certificate or certificates representing the shares of Common Stock of the Corporation to be delivered shall be duly
executed in blank by the Optionee or shall be accompanied by a stock power duly executed in blank suitable for purposes of transferring
such shares to the Corporation. Fractional shares of Common Stock of the Corporation will not be accepted in payment of the purchase
price of shares acquired upon exercise of this option.


 


(d) Restrictions
on Use of Option Stock. Notwithstanding the foregoing, no shares of Common Stock of the Corporation may be tendered in payment of
the purchase price of shares purchased upon exercise of this option if the shares to be so tendered were acquired within twelve (12)
months before the date of such tender through the exercise of an option granted under the Plan or any other stock option or restricted
stock plan of the Corporation.


 


 5. Delivery of Shares; Compliance with Securities Laws, Etc.




 


(a) General.
The Corporation shall, upon payment of the option price for the number of shares purchased and paid for, make prompt delivery of such
shares to the Optionee, provided that if any law or regulation requires the Corporation to take any action with respect to such shares
before the issuance thereof, then the date of delivery of such shares shall be extended for the period necessary to complete such action.


 


(b) Listing,
Qualification, Etc. This option shall be subject to the requirement that if, at any time, counsel to the Corporation shall
determine that the listing, registration or qualification of the shares subject hereto upon any securities exchange or under any
state or federal law, or the consent or approval of any governmental or regulatory body, or that the disclosure of non-public
information or the satisfaction of any other condition is necessary as a condition of, or in connection with, the issuance or
purchase of shares hereunder, this option may not be exercised, in whole or in part, unless such listing, registration,
qualification, consent or approval, disclosure or satisfaction of such other condition shall have been effected or obtained on terms
acceptable to the Administrator. Nothing herein shall be deemed to require the Corporation to apply for, effect or obtain such
listing, registration, qualification or disclosure, or to satisfy such other condition.

6. Nontransferability
of Option. Except as provided in paragraph (e) of Section 3, this option is personal and no rights granted hereunder may be transferred,
assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) nor shall any such rights be subject to execution,
attachment or similar process, except that this option may be transferred: (i) by will or the laws of descent and distribution or (ii)
pursuant to a qualified domestic relations order as defined in Section 414(p) of the Code. Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of this option or of such rights contrary to the provisions hereof, or upon the levy of any attachment
or similar process upon this option or such rights, this option and such rights shall, at the election of the Corporation, become null
and void.


 


7. No
Special Employment or Similar Rights. Nothing contained in the Plan or this option shall be construed or deemed by any person under
any circumstances to create or to bind the Corporation or any subsidiary to enter into or continue any relationship (whether employment,
independent contractor, agency, or other) of the Optionee with the Corporation or any subsidiary for the period within which this option
may be exercised.


 


8. Rights
as a Shareholder. The Optionee shall have no rights as a shareholder with respect to any shares which may be purchased by exercise
of this option (including, without limitation, any rights to receive dividends or non-cash distributions with respect to such shares)
unless and until a certificate representing such shares is duly issued and delivered to the Optionee. No adjustment shall be made for
dividends or other rights for which the record date is prior to the date such stock certificate is issued.


 


 9. Adjustment Provisions.




 


(a) General.
In the event of a merger, consolidation, sale of all or substantially all of the securities or assets, or reorganization, recapitalization,
etc. the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to an appropriate adjustment of the
shares to be issued pursuant to this option.


 


(b) Administrator
Authority to Make Adjustments. Any adjustments under this Section 9 will be made by the Administrator, whose determination as to
what adjustments, if any, will be made and the extent thereof will be final, binding and conclusive. No fractional shares will be issued
pursuant to this option on account of any such adjustments.


 


10. Mergers,
Consolidation, Distributions, Liquidations Etc. In the event of a merger, consolidation, distribution, liquidation or other similar
event, the Optionee shall, with respect to this option or any unexercised portion hereof, be entitled to the rights and benefits, and
be subject to the limitations, set forth in Article 9 of the Plan.

exemption from registration is then available; (C) in any event, an exemption from registration under Rule 144 or otherwise under
the Securities Act may not be available for at least two years and even then will not be available unless a public market then
exists for the Common Stock, adequate information concerning the Corporation is then available to the public, and other terms and
conditions of Rule 144 are complied with; and (D) there is now no registration statement on file with the Securities and Exchange
Commission with respect to any stock of the Corporation and the Corporation has no obligation or current intention to register any
shares acquired pursuant to the exercise of this option under the Securities Act.
