Options underlying an Option Grant shall vest over four years, commencing on the vesting commencement date (the "Vesting
Commencement Date") as determined by the Committee.

		7.	TERMINATION OF EMPLOYMENT WITH THE GROUP 



 


In the event

for whatever reason but subject to Section 7.6 (including but not limited to (i) dismissal of a Participant or (ii) a Participant’s
resignation, or (iii) death of a Participant or (iv) disability of a Participant), then the following provisions shall apply:

    	-5-



    

 


		7.3.	In the event that the Participant's termination of employment is not due to the Participant's death
(but does include termination due to Disability), then the Participant will be entitled to exercise all, or part of, the vested
Options that have not expired, for a period of thirty (30) days after the Employment Termination Date. After such thirty days period,
all unexercised Options will automatically expire.



For purposes
of this Section 7.3, "Disability" shall mean the inability in 100%, due to illness or injury, to engage in any gainful
occupation for which the individual is suited by education, training or experience, which condition continues for at least six
(6) months.

or Disability, the Participant (if applicable) or Participant's estate, or other person who acquired the right to exercise the
Options by way of bequest or inheritance, may, but only within six (6) months after the date of such death or the Employment Termination
Date (in the case of Disability), exercise all, or part of, the vested Options that have not expired. After such six (6) months
period, all unexercised options shall automatically expire.



		7.5.	Notwithstanding Section 7.3 above, all Options granted to a certain Employee (whether vested or
unvested) will immediately expire if the termination of the Participant’s employment is due to Participant’s breach
of his/her employment agreement (whether written or oral) including without limitation, a breach of non compete obligations, or
breach of his/her fiduciary duties towards the Company or a Related Entity as determined by the Committee or the Board, in their
sole discretion, or in the case that competent court or other authority resolves that such employee is not entitled to discharge
compensation.



		7.6.	For the purposes of this Plan, the Committee or Board is authorized to determine if and when a
Participant terminated his/her employment with the Company, and due to what reason, subject to the provisions of Israeli labor
laws with respect to Israeli employees.



		7.7.	The Committee or the Board shall be entitled, prospectively and retroactively, to extend the periods
in which Options (either vested or unvested) do not expire and remain exercisable after the Employment Termination Date.



 


		8.	TERMINATION OF ENGAGEMENT WITH THE GROUP 



 


In the event that a Participant
is not an Employee, and the agreement of such Participant with the Group is terminated, then, unless otherwise specified in the
Option Grant Letter Agreement, or otherwise determined by the Committee, on the date of such termination, all Options that have
not vested by then shall expire and the vested options shall remain exercisable as specified in sections 7.3, 7.4 or 7.5, as the
case may be, which shall apply mutatis mutandis to such Participant (where if such Participant has more than one agreement
with the Group, then the foregoing shall apply to the Options underlying the terminated agreement or issued in connection therewith).

		9.	ADJUSTMENTS

party or the sale of all, or substantially all of the assets of the Company (each of them, a “Transaction”),
then the following provisions shall apply:


		9.1.1.	Each outstanding Option shall be assumed by, or an equivalent option shall be substituted by the
successor corporation or a parent or subsidiary of the successor corporation.



		9.1.2.	In the event that the successor corporation does not agree to assume the Options or to substitute
them with equivalent options, the Committee may in lieu of such assumption or substitution, provide for the Participant to have
the right to exercise the Options as to all, or part of the Shares, including certain Shares as to which it would not otherwise
be exercisable.



		9.1.3.	In addition to Section 9.1.2 above, and if Section 9.1.1 does not apply, the Committee may notify
the Participants that all Options that are exercisable shall remain so for a period of no less then seven (7) days from the date
of such notice, and that all Options will terminate upon the expiration of such period. In any case, the Committee may condition
the termination of all said Options upon consummation of the Transaction.



		9.2.	Bonus Shares



In the event
that the Company issues any of its shares as bonus shares to all its shareholders, on a pro rata basis, then the number of Shares
received upon exercise of certain Options shall be increased to the number of Shares the Participant would have held after the
issuance of the bonus shares had such Participant exercised such Options immediately before the issuance of the bonus shares.


		9.3.	Reorganization; Separation



If the Company
is separated, reorganized, or consolidated with another corporation (other than as part of a Transaction) while Options which were
not yet exercised remain outstanding under this Plan, the Company shall use reasonable efforts to maintain the rights of each Participant
through such separations, reorganizations or consolidations, or compensate the Participant for such event in lieu of the Options
such Participant holds. The Committee, at its sole discretion, shall determine what steps shall be taken according to this section
9.3.

shares of the Company shall at anytime be changed or exchanged by declaration of a share split, reverse share split, combination
or reclassification of Ordinary Shares, or any other increase or decrease in the number Company’s Ordinary Shares effected
without receipt of consideration by the Company from the shareholders, then the number, class and kind of Shares subject to this
Plan or subject to any Options therefore granted, and the Exercise Prices of the Options, shall be appropriately and equitably
adjusted so as to maintain the proportionate number of Shares without changing the aggregate Exercise Prices of the Options (except
in case the Exercise Price is equal to the par value of the shares, in which case the Exercise Price will be increased respectively).
However no adjustment shall be made by reason of the distribution of subscription rights on outstanding shares, or conversion of
securities into shares of the Company.


		9.5.	Other terms and conditions



		9.5.1.	The allocation of each Option Grant hereunder is subject to the relevant Participant’s agreement

benefit shall immediately expire.

in such respect shall be final, binding and conclusive.



		9.5.3.	Anything herein to the contrary notwithstanding, if prior to an IPO, there is a bona fide offer
to purchase all or substantially all of the issued and outstanding shares of the Company, or upon a reorganization separation or
the like, all or substantially all of the shares of the Company are to be exchanged for securities of another company, then each
Participant shall be obliged to sell or exchange (in accordance with the value of such Participant’s Options and Shares pursuant
to the terms of such transaction) as the case may be, any Shares such Participant purchases hereunder, in accordance with the instructions
issued by the Board in connection with such transaction, which will be given according to a policy of the Board concerning all
of the Participants under the Plan.

rights to purchase Shares hereunder shall be exercisable only by such Participant.

to establish further processes for the purchase of the Options as set forth above, provided, however, that if the Company receives

to release any Share certificates or transfer any Shares to a Participant until all required tax payments have been fully made.

proceeds the Participant is entitled to receive from the Group or other proceeds such Participant owns and are held by the Group,
including from Participant’s salary or other proceeds he/she is entitled to receive from the Company or a Related Entity.
It is explicitly stated herein that each Participant who is an Employee, by accepting an Option Grant agrees to the deduction from

in the Plan or in any Option Grant shall confer upon any Participant any right to continue to be employed by the Group or to maintain
any other business engagement with it, or restrict the right of any entity included in the Group to terminate such employment or
business engagement at any time.

ADDENDUM


 


Terms of Options granted
to United States

Employees and Service Providers


 


		10.	Purpose of the Addendum



 


This Addendum (also referred
to as the "Addendum") is part of the 2010 Incentive Option Plan of Alocbra Ltd. (the "Plan").
All terms not otherwise defined herein shall have the meaning ascribed to them in the Plan. This Addendum governs grants of Options
to United States Employees and other Service Providers.


 


		11.	Provisions of the Addendum 



 


The provisions of the Addendum
shall supersede and govern in the case of inconsistency between the provisions of the Addendum and the provisions of the Plan,
provided, however, that this Addendum shall not be construed to grant to any Participant rights not consistent with the terms of
the Plan, unless specifically provided herein.


 


		12.	Eligibility





The individuals who shall be eligible to receive Option Grants under the Plan that are subject to the provisions of this Addendum
shall be employees, directors and other individuals and entities who are United States citizens or who are resident aliens of the
United States for United States federal tax purposes (collectively, “U.S. Persons”), and who render services
to the management, operation or development of the Company or a Subsidiary and who have contributed or may be expected to contribute
materially to the success of the Company or a Subsidiary. ISOs (as defined in Section 4 below) shall not be granted to any individual
who is not an employee of a corporation for United States federal tax purposes. The term “Subsidiary” as used
in this Addendum means a corporation or other business entity of which the Company owns, directly or indirectly through an unbroken
chain of ownership, fifty percent or more of the total combined voting power of all classes of stock.


 


		13.	Terms and Conditions of Options



 


Every Option
granted to a U.S. Person shall be evidenced by a written stock option agreement (the "Stock Option Agreement")
in such form as the Committee shall approve from time to time, specifying the number of Shares that may be purchased pursuant to
the Option, the time or times at which the Option shall become exercisable in whole or in part, whether the Option is intended
to be an incentive stock option (“ISO”) or a nonqualified stock option (“NSO”) and such other
terms and conditions as the Committee shall approve, and containing or incorporating by reference the following terms and conditions.
The Plan and this Addendum shall be administered in such a manner as to permit those Options granted hereunder and specially designated
as an ISO to qualify as incentive stock options as described in Section 422 of the Internal Revenue Code of 1986, as amended (the
“Code”).


 






    	 



    	-20-



    

 


(a)
Duration. Each Option shall expire no later than ten (10) years from its grant date; provided, however, that no ISO granted
to an Employee who owns (directly or under the attribution rules of Section 424(d) of the Code) stock possessing more than ten
percent of the total combined voting power of all classes of stock of the Company or any Subsidiary shall expire later than five
(5) years from its date of grant.


 


(b)
Exercise Price. The exercise price of each Option shall be as specified by the Committee in its discretion; provided, however,
that the price shall be at least 100 percent of the Fair Market Value (as hereinafter defined) of the Shares on the date on which
the Board grants the Option (or shareholders resolution to grant such options, if such resolution is required), which shall be
considered the date of grant of the Option for purposes of fixing the price; and provided, further, that the price with respect
to an ISO granted to an Employee who at the time of grant owns (directly or under the attribution rules of Section 424(d) of the
Code) stock representing more than ten percent (10%) of the voting power of all classes of stock of the Company or of any Subsidiary
shall be at least 110 percent of the Fair Market Value of the Shares on the date of grant of the ISO. For purposes of the Plan,
except as may be otherwise explicitly provided in the Plan or in any Stock Option Agreement, the “Fair Market Value”
of a Share at any particular date shall be determined according to the following rules: (i) if the Shares are not at the time listed
or admitted to trading on a stock exchange, the Fair Market Value shall be the closing price of the Shares on the date in question
in the over-the-counter market, as such price is reported in a publication of general circulation selected by the Board and regularly
reporting the price of the Shares in such market; provided, however, that if the price of the Shares is not so reported, the Fair
Market Value shall be determined in good faith by the Board, which may take into consideration (1) the price paid for the Shares
in the most recent trade of a substantial number of shares known to the Board to have occurred at arm’s length between willing
and knowledgeable investors, (2) an appraisal by an independent party or (3) any other method of valuation undertaken in good faith
by the Board, or some or all of the above as the Board shall in its discretion elect; or (ii) if the Shares are at the time listed
or admitted to trading on any stock exchange, then the Fair Market Value shall be the last known closing price of the Shares when
the relevant Option Grant is approved by the Company. Notwithstanding Subsection (ii) above, the Administrator may adopt any other
method in order to determine the Fair Market Value of a Share, as long as use of such method will not give rise to adverse tax
consequences under Internal Revenue Code Section 409A. 


 


(c)Notice
of ISO Stock Disposition. The Participant must notify the Company promptly in the event that he sells, transfers, exchanges
or otherwise disposes of any Shares issued upon exercise of an ISO before the later of (i) the second anniversary of the date of
grant of the ISO or (ii) the first anniversary of the date the shares were issued upon his exercise of the ISO.


 






    	 



    	-21-



    

 


(d)Effect
of Cessation of Employment or Service Relationship. The Committee shall determine in its discretion and specify in each Stock
Option Agreement the effect, if any, of the termination of the Participant’s employment with or performance of services for
the Company or any Subsidiary on the exercisability of the Option.


 


(e)No
Rights as Stockholder. A Participant shall have no rights as a stockholder with respect to any Shares covered by an Option
until the date of issuance of a stock certificate to him for the Shares. No adjustment shall be made for dividends or other rights
for which the record date is earlier than the date the stock certificate is issued, other than as required or permitted by the
Plan.


 


(f)Transferability
of Options. Except as permitted by the Committee, and set forth in the terms of a Participant’s Stock Option Agreement,
an Option shall not be assignable or transferable by the Participant except by will or by the laws of descent and distribution.
During the life of the Participant, an Option shall be exercisable only by him, by a conservator or guardian duly appointed for
him by reason of his incapacity or by the person appointed by the Participant in a durable power of attorney acceptable to the
Company’s counsel.


 


		14.	Requirements
of Law



 


		(a)	The Company shall not be required to transfer Shares or to sell or issue any Shares upon the exercise
of any Option if the issuance of such Shares will result in a violation by the Participant or the Company of any provisions of
any law, statute or regulation of any governmental authority. Specifically, in connection with the Securities Act of 1933, as amended
from time to time (the “Securities Act”), upon the exercise of any Option, the Company will not be required
to issue Shares unless the Committee has received evidence satisfactory to it to the effect that the holder of the Option will
not transfer such shares except pursuant to a registration statement in effect under the Securities Act or unless an opinion of
counsel satisfactory to the Company has been received by the Company to the effect that registration is not required. Any determination
in this connection by the Committee shall be conclusive. The Company shall not be obligated to take any other affirmative action
in order to cause the exercise of an Option to comply with any law or regulations of any governmental authority, including, without
limitation, the Securities Act or applicable state securities laws.



 


		(b)	All other provisions of this Addendum and the Plan notwithstanding, this Addendum and the Plan
shall be administered and construed so as to avoid any person who receives an Option Grant incurring any adverse tax consequences
under Internal Revenue Code Section 409A. The Administrator shall suspend the application of any provisions of the Plan which could,
in its sole determination, result in an adverse tax consequence to any person under Internal Revenue Code Section 409A.



 






    	 



    	-22-



    

 


		15.	Forfeiture for Dishonesty or Termination for Cause 



 


Notwithstanding
any provision of the Plan to the contrary, if the Committee determines, after full consideration of the facts, that:


 


(a)
the Participant has been engaged in fraud, embezzlement, theft or commission of a felony in the course of his or her employment
by or involvement with the Company, a Subsidiary or a parent corporation as defined in Section 424 of the Code or any direct or
indirect subsidiary of such parent (an “Affiliate”) or has made unauthorized disclosure of trade secrets or
other proprietary information of the Company, a Subsidiary, an Affiliate or of a third party who has entrusted such information
to the Company, a Subsidiary or an Affiliate; or


 


(b)
the Participant has violated the terms of any employment, noncompetition, nonsolicitation or proprietary information agreement
to which he is a party; or


 


(c)
the Participant’s employment or involvement with the Company, a Subsidiary or an Affiliate was terminated for “cause,”
as defined in any employment agreement with the Participant, if applicable, or if there is no such agreement, as determined by
the Committee, which may determine that “cause” includes among other matters the willful failure or refusal of the
Participant to perform and carry out his or her assigned duties and responsibilities diligently and in a manner satisfactory to
the Committee;


 


then the Participant’s
right to exercise an Option shall terminate as of the date of such act (in the case of (a) or (b)) or such termination (in the
case of (c)), the Participant shall forfeit all unexercised Options and shall be required to sell to the Company or, in the case
the Company is not allowed to repurchase its own shares, to a third party approved by the Company, all or any part of the Shares
acquired by the Participant prior to such event, at a price equal to the lesser of their Fair Market Value or the amount paid to
the Company upon such transfer or exercise. If a Participant whose behavior the Company asserts falls within the provisions of
(a), (b) or (c) above has exercised or attempts to exercise an Option prior to consideration of the application of this Section
6 or prior to a decision of the Committee, the Company shall not be required to recognize such exercise until the Committee has
made its decision and, in the event any exercise shall have taken place, it shall be of no force and effect (and shall be void
ab initio) if the Committee makes an adverse determination, provided, however, that if the Committee finds in favor
of the Participant then the Participant will be deemed to have exercised the Option retroactively as of the date he or she originally
gave notice of his or her attempt to exercise or actual exercise, as the case may be. The decision of the Committee as to the cause
of a Participant’s discharge and the damage done to the Company shall be final, binding and conclusive. No decision of the
Committee, however, shall affect in any manner the finality of the discharge of such Participant by the Company. For purposes of
this Section 6, reference to the Company shall include any Subsidiary or Affiliate.


 





		16.	Tax Withholding 



 


To the extent required by law,
the Company may withhold or cause to be withheld income and other taxes with respect to any income recognized by a Participant
by reason of the exercise of an Option, and as a condition to the receipt of any Option the Participant shall agree that if the
amount payable to him by the Company and any Subsidiary in the ordinary course is insufficient to pay such taxes, then he shall
upon the request of the Company pay to the Company an amount sufficient to satisfy its tax.
