4. Shares Subject To Plan.


LR17.03(3) 


 


4.1
(a) Maximum Number of Shares Issuable. Subject to adjustments and requirements of the Listing Rules, in particular
Section 4.2 and Section 4.1(b) to 4.1(d) in the Addendum A, the maximum aggregate number of shares of Stock that may be
issued under the Plan shall be, subject to the separate approval of the shareholders of the Company and the shareholders of
ASL and the requirements of applicable law, no more than 5,000,000 (five million), which shall consist of authorized but
unissued or reacquired shares of Stock or any combination thereof. If an
outstanding Award for any reason expires or is terminated or canceled or if shares of Stock are acquired upon the exercise of
an Award subject to a Company repurchase option and are repurchased by the Company at the Participant’s exercise or
purchase price, the shares of Stock allocable to the unexercised portion of such Award or such repurchased shares of Stock
shall again be available for issuance under the Plan. Notwithstanding the foregoing, at any such time as the offer and sale
of securities pursuant to the Plan is subject to compliance with Section 260.140.45 of Title 10 of the California Code of
Regulations (“Section 260.140.45”), the total number of shares of Stock issuable upon
the exercise of all outstanding Awards (together with options outstanding under any other stock plan of the Company) and the
total number of shares provided for under any stock bonus or similar plan of the Company shall not exceed thirty percent
(30%) (or such other higher percentage limitation as may be approved by the shareholders of the Company pursuant to Section
260.140.45) of the then outstanding shares of the Company as calculated in accordance with the conditions and exclusions of
Section 260.140.45.


 


4.2 Adjustments
for Changes in Capital Structure. Subject to any required action by the shareholders of the Company, in the event of any change
in the Stock effected without receipt of consideration by the Company, whether through merger, consolidation, reorganization, reincorporation,
recapitalization, reclassification, stock dividend, stock split, reverse stock split, split-up, split-off, spin-off, combination
of shares, exchange of shares, or similar change in the capital structure of the Company, or in the event of payment of a dividend
or distribution to the shareholders of the Company in a form other than Stock (excepting normal cash dividends) that has a material
effect on the Fair Market Value of shares of Stock, appropriate and proportionate adjustments shall be made in the number and class
of shares subject to the Plan and to any outstanding Awards, in the ISO Share Limit set forth in Section 5.3(a), and in the exercise
or purchase price per share of any outstanding Awards in order to prevent dilution or enlargement of Participants’ rights
under the Plan. For purposes of the foregoing, conversion of any convertible securities of the Company shall not be treated as
“effected without receipt of consideration by the Company.” If a majority of the shares which are of the same class
as the shares that are subject to outstanding Awards are exchanged for, converted into, or otherwise become (whether or not pursuant
to an Ownership Change Event) shares of another corporation (the “New Shares”), the Committee may unilaterally
amend the outstanding Awards to provide that such Awards are for New Shares. In the event of any such amendment, the number of
shares subject to, and the exercise or purchase price per share of, the outstanding Awards shall be adjusted in a fair and equitable
manner as determined by the Committee, in its discretion. Any fractional share resulting from an adjustment pursuant to this Section
4.2 shall be rounded down to the nearest whole number, and the exercise price per share shall be rounded up to the nearest whole
cent. In no event may the exercise price of any Award be decreased to an amount less than the par value, if any, of the stock subject
to the Award. Such adjustments shall be determined by the Board, and its determination shall be final, binding and conclusive.


 


5. Eligibility
and Option Limitations.


 


5.1 Persons
Eligible for Awards. Awards may be granted only to Employees, Consultants and Directors.


 






    8


     


    

 


5.2 Participation
in Plan. Awards are granted solely at the discretion of the Board. Eligible persons may be granted more than one Award.
However, eligibility in accordance with this Section shall not entitle any person to be granted an Award, or, having been
granted an Award, to be granted an additional Award.


 


5.3 Incentive
Stock Option Limitations.


 


(a) Maximum
Number of Shares Issuable Pursuant to Incentive Stock Options. The maximum aggregate number of shares of Stock that may be
issued under the Plan pursuant to all Awards other than Incentive Stock Options shall be the number of shares reserved for issuance
under the Plan and determined in accordance with Section 4.1 (the “ISO Share Limit”), subject to adjustment
as provided in Section 4.2.


 


(b) Persons
Eligible. An Incentive Stock Option may be granted only to a person who, on the effective date of grant, is an Employee. Any
person who is not an Employee on the effective date of the grant of an Option to such person may be granted only a Nonstatutory
Stock Option. An Incentive Stock Option granted to a prospective Employee upon the condition that such person become an Employee
shall be deemed granted effective on the date such person commences Service as an Employee, with an exercise price determined as
of such date in accordance with Section 6.1.


 


(c) Fair
Market Value Limitation. To the extent that options designated as Incentive Stock Options (granted under all stock plans of
the Participating Company Group, including the Plan) become exercisable by a Participant for the first time during any calendar
year for stock having a Fair Market Value greater than One Hundred Thousand Dollars ($100,000), the portions of such options which
exceed such amount shall be treated as Nonstatutory Stock Options. For purposes of this Section 5.3, options designated as Incentive
Stock Options shall be taken into account in the order in which they were granted, and the Fair Market Value of stock shall be
determined as of the time the option with respect to such stock is granted. If the Code is amended to provide for a different limitation
from that set forth in this Section, such different limitation shall be deemed incorporated herein effective as of the date and
with respect to such Options as required or permitted by such amendment to the Code. If an Option is treated as an Incentive Stock
Option in part and as a Nonstatutory Stock Option in part by reason of the limitation set forth in this Section, the Participant
may designate which portion of such Option the Participant is exercising. In the absence of such designation, the Participant shall
be deemed to have exercised the Incentive Stock Option portion of the Option first. Separate certificates representing each such
portion shall be issued upon the exercise of the Option.


 


6. Terms
and Conditions of Options.


 


Options shall be evidenced by Award Agreements specifying the number of shares of Stock covered thereby, in such form as the Board shall from time to time establish. Award Agreements may incorporate all or any of the terms of the Plan by reference and shall comply with and be subject to the following terms and conditions:


 


LR17.03(9) 


 


6.1 Exercise
Price. The exercise price for each Option shall be established in the discretion of the Board; provided, however, that
the exercise price per share for an Option shall be not less than the Fair Market Value of a share of Stock on the effective
date of grant of the Option. Notwithstanding the foregoing, an Option (whether an Incentive Stock Option or a Non statutory
Stock Option) may be granted with an exercise price lower than the minimum
exercise price set forth above if such Option is granted pursuant to an assumption or substitution for another option in a
manner qualifying under the provisions of Section 424(a) of the Code.


 






    9


     


    

 


6.2 Exercisability and
Term of Options. Options shall be exercisable at such time or times, or upon such event or events, and subject to such
terms, conditions, performance criteria and restrictions (including, without limitation, any minimum period for which an
Award must be held before it can be exercised and/or any performance targets which must be achieved before an Award can be
exercised) as shall be determined by the Board and set forth in the Award Agreement evidencing such Option; provided,
however, that (a) no Option shall be exercisable after the expiration of ten (10) years after the effective date of grant of
such Option, (b) no Incentive Stock Option granted to a Ten Percent Shareholder shall be exercisable after the expiration of
five (5) years after the effective date of grant of such Option, and (c) with the exception of (i) an Option granted to an
Officer, a Director or a Consultant and (ii) an Option that is exercisable based on the accomplishment of specific
performance-based milestones, no Option shall become exercisable at a rate less than twenty percent (20%) per year over a
period of five (5) years from the effective date of grant of such Option, subject to the Participant’s continued
Service. Subject to the foregoing, unless otherwise specified by the Board in the grant of an Option, any Option granted
hereunder shall terminate ten (10) years after the effective date of grant of the Option, unless earlier terminated in
accordance with its provisions. Any Awards granted but not exercised may be cancelled if the Participant so agrees and new
Awards may be granted to the Participant provided that such new Awards fall within the limits prescribed by Section 4.1,
excluding the cancelled Awards, and are otherwise granted in accordance with the terms of the Plan.


 


 6.3 Payment of Exercise
Price.


 


(a) Forms
of Consideration Authorized. Except as otherwise provided below, payment of the exercise price for the number of shares
of Stock being purchased pursuant to any Option shall be made (i) in cash or by check or cash equivalent, (ii) by tender to the
Company, or attestation to the ownership, of shares of Stock owned by the Participant having a Fair Market Value not less than
the exercise price, (iii) by delivery of a properly executed notice together with irrevocable instructions to a broker providing
for the assignment to the Company of the proceeds of a sale or loan with respect to some or all of the shares being acquired upon
the exercise of the Option (including, without limitation, through an exercise complying with the provisions of Regulation T as
promulgated from time to time by the Board of Governors of the Federal Reserve System) (a “Cashless Exercise”),
(iv) by promissory note, (v) by such other consideration as may be approved by the Board from time to time to the extent permitted
by applicable law, or (vi) by any combination thereof. The Board may at any time or from time to time, by approval of or by amendment
to the standard forms of Award Agreement described in Section 8, or by other means, grant Options which do not permit all of the
foregoing forms of consideration to be used in payment of the exercise price or which otherwise restrict one or more forms of consideration.


 






    10


     


    

 


(b) Limitations
on Forms of Consideration.


 


(i) Tender of
Stock. Notwithstanding the foregoing, an Option may not be exercised by tender to the Company, or attestation to the
ownership, of shares of Stock to the extent such tender or attestation would constitute a violation of the provisions of any
law, regulation or agreement restricting the redemption of the Company’s stock. Unless otherwise provided by the Board,
an Option may not be exercised by tender to the Company, or attestation to the ownership, of shares of Stock unless such
shares either have been owned by the Participant for more than six (6) months (and were not used for another Option exercise
by attestation during such period) or were not acquired, directly or indirectly, from the Company.


 


(ii) Cashless Exercise. The
Company reserves, at any and all times, the right, in the Company’s sole and absolute discretion, to establish, decline
to approve or terminate any program or procedures for the exercise of Options by means of a Cashless Exercise.


 


6.4 Lapse
of Options.


 


(a) Option
Exercisability. Subject to earlier termination
of the Option as otherwise provided by this Plan and unless a longer exercise period is provided by the Board in the grant of an
Option and set forth in the Award Agreement, an Option shall terminate immediately upon the Participant’s termination of
Service to the extent that it is then unvested and shall be exercisable after the Participant’s termination of Service to
the extent it is then vested only during the applicable time period determined in accordance with this Section and thereafter shall
terminate:


 


(i) Disability.
If the Participant’s Service terminates because of the Disability of the Participant, the Option, to the extent unexercised
and exercisable on the date on which the Participant’s Service terminated, may be exercised by the Participant (or the Participant’s
guardian or legal representative) at any time prior to the expiration of the Option’s term as set forth in the Award Agreement
evidencing such Option (the “Option Expiration Date”) or such other period of time as is
set forth in the Notice of Grant of Stock Option.


 


(ii) Death.
If the Participant’s Service terminates because of the death of the Participant, the Option, to the extent unexercised
and exercisable on the date on which the Participant’s Service terminated, may be exercised by the Participant’s legal
representative or other person who acquired the right to exercise the Option by reason of the Participant’s death at any
time prior to the expiration of the Option Expiration Date or such other period of time as is set forth in the Notice of Grant
of Stock Option. The Participant’s Service shall be deemed to have terminated on account of death if the Participant dies
within three (3) months (or such longer period of time as determined by the Board, in its discretion) after the Participant’s
termination of Service.


 


(iii) Termination
for Cause. Notwithstanding any other provision of the Plan to the contrary, if the Participant’s Service with the Participating
Company Group is terminated for Cause, the Option shall terminate and cease to be exercisable immediately upon such termination
of Service.


 


(iv)
Other Termination of Service. If the Participant’s Service terminates for any reason, except Disability, death or
Cause, the Option, to the extent unexercised and exercisable by the Participant on the date on which the Participant’s
Service terminated, may be exercised by the Participant at any time prior to the expiration of the Option Expiration Date or
such other period of time as is set forth in the Notice of Grant of Stock Option.


 






    11


     


    

 


(b) Extension
if Exercise Prevented by Law. Notwithstanding the foregoing other than termination for Cause, if the exercise of an Option
within the applicable time periods set forth in Section 6.4(a) is prevented by the provisions of Section 11 below, the Option shall
remain exercisable until thirty (30) days after the date such exercise first would no longer be prevented by such provisions, but
in any event no later than the Option Expiration Date.


 


6.5 Transferability
of Options. During the lifetime of the Participant, an Option shall be exercisable only by the Participant or the Participant’s
guardian or legal representative. No Option shall be assignable or transferable by the Participant, except by will or by the laws
of descent and distribution or to a revocable trust. Notwithstanding the foregoing, to the extent permitted by the Board, in its
discretion, and set forth in the Award Agreement evidencing such Option, a Nonstatutory Stock Option shall be assignable or transferable
subject to the applicable limitations, if any, described in Section 260.140.41 of Title 10 of the California Code of Regulations,
Rule 701 under the Securities Act, and the General Instructions to Form S-8 Registration Statement under the Securities Act.


 


7. True-up
Policy.


 


7.1. Covenant
to Grant True-up Options. Covenant to Grant True-up Options. Subject to separate approval by its shareholders in connection
with the adoption of the Plan, the Board has adopted a True-Up Option Policy (“Policy”), which provides
as follows:


 


(a) The
purpose of the Policy is to protect Participants under the Plan from the dilutive effects of subsequent qualified equity financings
(“Financings”) by the Company.


 


(b) For
the purposes of this Policy, a Financing is qualified if it results in an issuance of a new stock or recapitalization of existing
stock leading to dilution of the Participant’s share of the Company value, regardless of the value of the consideration tendered
for the stock, if any.


 


(c) The
Policy will be implemented by granting options for shares of Stock after each Financing to all eligible Participants under the
Plan, provided such Participants (a) have received options under this Plan before the latest Financing and (b) remain eligible
to receive options under the regular eligibility criteria of the Plan (“Qualified Participants”).


 


(d) The
options will be granted at the then fair market value of the Stock.


 


(e) The
number of shares of Stock that may be issued upon exercise of all Options to be granted to each Qualified Participant as may reasonably
be determined by the Board at each Financing will be calculated based on the dilution of the equity value of such Participant.


 


(f) This
Policy shall remain in effect until such time as the Company has raised one hundred million U.S. Dollars ($100,000,000) in aggregate
Financings.


 






    12


     


    

 


(g) Upon exceeding
one hundred million U.S. Dollars ($100,000,000) in aggregate Financing, the Policy will no longer apply to the extent any Financing
(or part thereof) exceeded the aforesaid aggregate threshold.


 


Notwithstanding anything
to the contrary contained herein, this Section 7.1 may not be amended without the approval of the Board, including the chief executive
officer of the Company.


 


8. Standard
Forms of Award Agreements.


 


8.1 Award Agreements. Each
Award shall comply with and be subject to the terms and conditions set forth in the appropriate form of Award Agreement
approved by the Board and as amended from time to time. No Award or purported Award shall be a valid and binding obligation
of the Company unless evidenced by a fully executed Award Agreement. Any Award Agreement may consist of an appropriate form
of Notice of Grant and a form of Agreement incorporated therein by reference, or such other form or forms, including
electronic media, as the Committee may approve from time to time.


 


8.2 Authority to Vary
Terms. The Board shall have the authority from time to time to vary the terms of any standard form of Award Agreement
either in connection with the grant or amendment of an individual Award or in connection with the authorization of a new
standard form or forms; provided, however, that the terms and conditions of any such new, revised or amended standard form or
forms of Award Agreement are not inconsistent with the terms of the Plan.


 


9. Change
in Control.


 


 9.1 Effect of Change
in Control on Awards.


 


(a) Accelerated
Vesting. The Board may, in its sole discretion, provide in any Award Agreement or, in the event of a Change in Control,
may take such actions as it deems appropriate to provide for the acceleration of the exercisability and vesting in connection with
such Change in Control of any or all outstanding Awards and shares acquired upon the exercise thereof upon such conditions, including
termination of the Participant’s Service prior to, upon, or following such Change in Control, and to such extent as the Board
shall determine.


 


(b)
Assumption or Substitution of Awards. In the event of a Change in Control, the surviving, continuing, successor, or
purchasing corporation or other business entity or parent thereof, as the case may be (the
“Acquiror”), may, without the consent of any Participant, either assume or continue the
Company’s rights and obligations under each or any Award or portion thereof outstanding immediately prior to the Change
in Control or substitute for each or any such outstanding Award or portion thereof a substantially equivalent award for the
Acquiror’s stock; provided however, that in the event any cash is to be paid by the Acquiror to the Company’s
shareholders in connection with the Change of Control, the Company must, unless otherwise agreed to by the Participant, cash
out the vested portion of the Award (and unvested portion of the Award, to the extent determined by the Board in accordance
with Subsection (c) below) pursuant to Subsection (c) below. For purposes of this Section, an Award shall be deemed assumed
if, following the Change in Control, the Award confers the right to receive, subject to the terms and conditions of the Plan
and the applicable Award Agreement, for each share of Stock subject to the Award immediately prior to the Change in Control,
the consideration (whether stock, cash, other securities or property or a combination thereof) to which a holder of a share
of Stock on the effective date of the Change in Control was entitled. Any Award or portions thereof which are neither assumed
or continued by the Acquiror in connection with the Change in Control nor exercised nor cashed out pursuant to Subsection (c)
below as of the time of consummation of the Change in Control shall terminate and cease to be outstanding effective as of the
time of consummation of the Change in Control. Notwithstanding the foregoing, shares acquired upon exercise of an Award prior
to the Change in Control and any consideration received pursuant to the Change in Control with respect to such shares shall
continue to be subject to all applicable provisions of the Award Agreement evidencing such Award except as otherwise provided
in such Award Agreement.


 






    13


     


    

 


(c) Cash-Out
of Awards. The Board may, in its sole discretion and without the consent of any Participant, determine that, upon the occurrence
of a Change in Control, each or any Award outstanding immediately prior to the Change in Control shall be canceled in exchange
for a payment with respect to each vested share (and each unvested share, if so determined by the Board) of Stock subject to such
canceled Award in cash in an amount having a Fair Market Value equal to the Fair Market Value of the consideration to be paid per
share of Stock in the Change in Control over the exercise price per share under such Award (the “Spread”).
In the event such determination is made by the Board, the Spread (reduced by applicable withholding taxes, if any) shall be paid
to Participants in respect of their canceled Awards as soon as practicable following the date of the Change in Control and in respect
of the unvested portion of their canceled Awards in accordance with the vesting schedule applicable to such Awards as in effect
prior to the Change in Control.


 


9.2 Federal
Excise Tax Under Section 4999 of the Code.


 


(a) Excess
Parachute Payment. In the event that any acceleration of vesting pursuant to an Award and any other payment or benefit
received or to be received by a Participant would subject the Participant to any excise tax pursuant to Section 4999 of the Code
due to the characterization of such acceleration of vesting, payment or benefit as an “excess parachute payment” under
Section 280G of the Code, the Participant may elect, in his or her sole discretion, to reduce the amount of any acceleration of
vesting called for under the Award in order to avoid such characterization.


 


(b)
Determination by Independent Accountants. To aid the Participant in making any election called for under Section
9.2(a), no later than the date of the occurrence of any event that might reasonably be anticipated to result in an
“excess parachute payment” to the Participant as described in Section 9.2(a), the Company shall request a
determination in writing by independent public accountants selected by the Company (the “Accountants”). As
soon as practicable thereafter, the Accountants shall determine and report to the Company and the Participant the amount of
such acceleration of vesting, payments and benefits which would produce the greatest after-tax benefit to the Participant.
For the purposes of such determination, the Accountants may rely on reasonable, good faith interpretations concerning the
application of Sections 280G and 4999 of the Code. The Company and the Participant shall furnish to the Accountants such
information and documents as the Accountants may reasonably request in order to make their required determination. The
Company shall bear all fees and expenses the Accountants may reasonably charge in connection with their services contemplated
by this Section 9.2(b).


 






    14


     


    

 


10. Tax
Withholding.


 


10.1 Tax
Withholding in General. The Company shall have the right to deduct from any and all payments made under the Plan,
or to require the Participant, through payroll withholding, cash payment or otherwise, including by means of a Cashless
Exercise of an Option, to make adequate provision for, the federal, state, local and foreign taxes (including income taxes,
payment on account and employment taxes or social insurance contributions), if any, required by law to be withheld by the
Participating Company Group with respect to an Award or the shares acquired pursuant thereto. The Company shall have no
obligation to deliver shares of Stock or to release shares of Stock from an escrow established pursuant to an Award Agreement
until the Participating Company Group’s tax withholding obligations have been satisfied by the Participant.


 


10.2 Withholding in
Shares. The Company shall have the right, but not the obligation, to deduct from the shares of Stock issuable to a Participant
upon the exercise of an Award, or to accept from the Participant the tender of, a number of whole shares of Stock having a Fair
Market Value, as determined by the Company, equal to all or any part of the tax withholding obligations of the Participating Company
Group. The Fair Market Value of any shares of Stock withheld or tendered to satisfy any such tax withholding obligations shall
not exceed the amount determined by the applicable minimum statutory withholding rates.


 


11. Compliance
with Securities Law.


 


The grant of Awards and
the issuance of shares of Stock upon exercise of Awards shall be subject to compliance with all applicable requirements of federal,
state and foreign law with respect to such securities. Awards may not be exercised if the issuance of shares of Stock upon exercise
would constitute a violation of any applicable federal, state or foreign securities laws or other law or regulations or the requirements
of any stock exchange or market system upon which the Stock may then be listed. In addition, no Award may be exercised unless (a)
a registration statement under the Securities Act shall at the time of exercise of the Award be in effect with respect to the shares
issuable upon exercise of the Award or (b) in the opinion of legal counsel to the Company, the shares issuable upon exercise of
the Award may be issued in accordance with the terms of an applicable exemption from the registration requirements of the Securities
Act. The inability of the Company to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s
legal counsel to be necessary to the lawful issuance and sale of any shares hereunder shall relieve the Company of any liability
in respect of the failure to issue or sell such shares as to which such requisite authority shall not have been obtained. As a
condition to the exercise of any Award, the Company may require the Participant to satisfy any qualifications that may be necessary
or appropriate, to evidence compliance with any applicable law or regulation and to make any representation or warranty with respect
thereto as may be requested by the Company.


 






    15


     


    

 


In connection with
the foregoing, the terms set forth in Addendum A shall only apply for so long as ASL is required to impose such provisions
under applicable laws and/or the Listing Rules.


 


12. Amendment
or Termination of Plan.


 


12.1 Amendment
or Termination of the Plan. The Board may amend, suspend or terminate the Plan at any time. However, subject to changes in
applicable law, regulations or rules that would permit otherwise, without the approval of the Company’s shareholders, there
shall be (a) no increase in the maximum aggregate number of shares of Stock that may be issued under the Plan (except as may be
permitted by the Listing Rules and by operation of the provisions of Section 4.2), (b) no change in the class of persons eligible
to receive Incentive Stock Options, and (c) no other amendment of the Plan that would require approval of the Company’s shareholders
under any applicable law, regulation or rule, including the rules of any stock exchange or market system upon which the Stock may
then be listed. No amendment, suspension or termination of the Plan shall affect any then outstanding Award unless expressly provided
by the Board. Except as provided by the next sentence, no amendment, suspension or termination of the Plan may adversely affect
any then outstanding Award without the consent of the Participant. Notwithstanding any other provision of the Plan to the contrary,
the Board may, in its sole and absolute discretion and without the consent of any participant, amend the Plan or any Award Agreement,
to take effect retroactively or otherwise, as it deems necessary or advisable for the purpose of conforming the Plan or such Award
Agreement to any present or future law, regulation or rule applicable to the Plan, including, but not limited to, Section 409A
of the Code.


 


13. Miscellaneous
Provisions.


 


13.1 Repurchase
Rights. Shares issued under the Plan may be subject to a right of first refusal, one or more repurchase options, or other conditions
and restrictions as determined by the Board in its discretion at the time the Award is granted. The Company shall have the right
to assign at any time any repurchase right it may have, whether or not such right is then exercisable, to one or more persons as
may be selected by the Company. Upon request by the Company, each Participant shall execute any agreement evidencing such transfer
restrictions prior to the receipt of shares of Stock hereunder and shall promptly present to the Company any and all certificates
representing shares of Stock acquired hereunder for the placement on such certificates of appropriate legends evidencing any such
transfer restrictions.


 


13.2 Provision
of Information. At least annually, copies of the Company’s balance sheet and income statement for the just completed
fiscal year shall be made available to each Participant and purchaser of shares of Stock upon the exercise of an Award. The Company
shall not be required to provide such information to key employees whose duties in connection with the Company assure them access
to equivalent information. Furthermore, the Company shall deliver to each Participant such disclosures as are required in accordance
with Rule 701 under the Securities Act.


 






    16


     


    

 


13.3 Rights as
Employee, Consultant or Director. No person, even though eligible pursuant to Section 5, shall have a right to be
selected as a Participant, or, having been so selected, to be selected again as a Participant. Nothing in the Plan or any
Award granted under the Plan shall confer on any Participant a right to remain an Employee, Consultant or Director or
interfere with or limit in any way any right of a Participating Company to terminate the Participant’s Service at any
time. To the extent that an Employee of a Participating Company other than the Company receives an Award under the Plan, that
Award shall in no event be understood or interpreted to mean that the Company is the Employee’s employer or that the
Employee has an employment relationship with the Company.


 


13.4 Rights as
a Shareholder. A Participant shall have no rights as a shareholder with respect to any shares covered by an Award until the
date of the issuance of such shares (as evidenced by the appropriate entry on the books of the Company or of a duly authorized
transfer agent of the Company). No adjustment shall be made for dividends, distributions or other rights for which the record date
is prior to the date such shares are issued, except as provided in Section 4.2 or another provision of the Plan. The shares of
Stock to be allotted upon the exercise of an Award shall be subject to all the provisions of the Bylaws of the Company for the
time being in force and shall rank pari passu in all respects with the existing fully paid shares in issue on the date on
which those shares of Stock are allotted on exercise of the Award and accordingly shall entitle the holders to participate in all
dividends or other distributions paid or made after the date on which shares are allotted other than any dividends or distributions
previously declared or recommended or resolved to be paid or made if the record date thereof shall be on or before the date on
which the shares are allotted.


 


13.5 Fractional
Shares. The Company shall not be required to issue fractional shares upon the exercise or settlement of any Award.


 


13.6 Retirement
and Welfare Plans. Neither Awards made under this Plan nor shares of Stock or cash paid pursuant to such Awards shall be included
as “compensation” for purposes of computing the benefits payable to any Participant under any Participating Company’s
retirement plans (both qualified and non-qualified) or welfare benefit plans unless such other plan expressly provides that such
compensation shall be taken into account in computing such benefits.


 


13.7 Severability.
If any one or more of the provisions (or any part thereof) of this Plan shall be held invalid, illegal or unenforceable in
any respect, such provision shall be modified so as to make it valid, legal and enforceable, and the validity, legality and enforceability
of the remaining provisions (or any part thereof) of the Plan shall not in any way be affected or impaired thereby.


 


13.8 No Constraint
on Corporate Action. Nothing in this Plan shall be construed to: (a) limit, impair, or otherwise affect the Company’s
or another Participating Company’s right or power to make adjustments, reclassifications, reorganizations, or changes of
its capital or business structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its
business or assets; or (b) limit the right or power of the Company or another Participating Company to take any action which such
entity deems to be necessary or appropriate.


 






    17


     


    

 


13.9 Choice of
Law. Except to the extent governed by applicable U.S. federal law, the validity, interpretation, construction and
performance of the Plan and each Award Agreement shall be governed by the laws of the State of California, without regard to
its conflict of law rules. Any disputes under the Plan shall be resolved only in the state and federal courts located in
Contra Costa County, California.


 


13.10 Shareholder
Approval. The Plan or any increase in the maximum aggregate number of shares of Stock issuable thereunder as provided in Section
4.1 (the “Authorized Shares”) shall be approved by a majority of the outstanding securities of
the Company entitled to vote by the later of (i) within twelve (12) months before or after the date of adoption of the Plan or
the date the agreement is entered into or (ii) prior to or within twelve (12) months of the granting of any Option or issuance
of any security under the Plan or agreement in California. Any options granted to any person in California that is exercised before
security holder approval is obtained shall be rescinded if security holder approval is not obtained as the manner described in
the preceding sentence. Awards granted prior to security holder approval of the Plan or in excess of the Authorized Shares previously
approved by the security holders shall become exercisable no earlier than the date of security holder approval of the Plan or such
increase in the Authorized Shares, as the case may be.

of ASL (excluding the independent non-executive director of ASL who is the relevant Participant).


 


(b) Where
the Board proposes to grant Options to a Participant who is a substantial shareholder or an independent non-executive director
of ASL, or any of their respective associates, which would result in the shares issued and to be issued upon exercise of all Awards
already granted and to be granted (including options exercised, cancelled and outstanding) to such Participant under the Plan and

new Section 12.2 as follows:



 


12.2 Any amendment of the Plan

GRID DYNAMICS INTERNATIONAL, INC.

2018 STOCK PLAN

STOCK OPTION AGREEMENT

FOR U.S. GRANTS


 


1. Grant
of Option. Grid Dynamics International, Inc., a California corporation (the “Company”), hereby grants to
the person (“Optionee”), named in the Notice of Grant of Stock Option (the “Notice”), an
option (the “Option”) to purchase the total number of shares of Common Stock (the “Shares”),
at the exercise price per Share set forth in the Notice (the “Exercise Price”) subject to the terms, definitions
and provisions of the Grid Dynamics International, Inc. 2018 Stock Plan (including Addendum A attached thereto, the “Plan”),
which is incorporated in this Stock Option Agreement (this “Agreement”) by reference. Unless otherwise defined
in this Agreement, the terms used in this Agreement or the Notice shall have the meanings defined in the Plan. The vested Shares
and the Unvested Shares (as defined below) are entitled to the same rights as shares of the Company’s Common Stock, including
rights to receive dividends or other distributions to shareholders as well as the right to vote the vested Shares and Unvested
Shares.


 


2. Designation
of Option. This Option is intended to be an Incentive Stock Option as defined in Section 422 of the Code only to the extent
so designated in the Notice, and to the extent it is not so designated or to the extent this Option does not qualify as an Incentive
Stock Option, it is intended to be a Nonstatutory Stock Option.


 


Notwithstanding
the above, if designated as an Incentive Stock Option, in the event that the Shares subject to this Option (and all other incentive
stock options granted to Optionee by the Company or any Parent or Subsidiary, including under other plans) that first become exercisable
in any calendar year have an aggregate fair market value (determined for each Share as of the date of grant of the option covering
such Share) in excess of $100,000, the Shares in excess of $100,000 shall be treated as subject to a nonstatutory stock option,
in accordance with the Plan.


 


3. Exercise
of Option. This Option shall be exercisable during its term in accordance with the Vesting/Exercise Schedule set out in the
Notice and with the provisions of Section 6.4 of the Plan as follows:


 


(a) Right
to Exercise.


 


(i) This
Option may not be exercised for a fraction of a share.


 


(ii) In
the event of Optionee’s death, Disability or other termination of Service, the exercisability of this Option is governed
by Section 5 below, subject to the limitations contained in this Section 3.


 


(iii) In
no event may this Option be exercised after the Option Expiration Date set forth in the Notice.


 






    23


     


    

 


(b) Method
of Exercise.


 


(i) This
Option shall be exercisable by execution and delivery of the exercise notice attached hereto as Exhibit A, the exercise
agreement attached hereto as Exhibit B or of any other form of written notice approved for such purpose by the Company which
shall state Optionee’s election to exercise this Option, the number of Shares in respect of which this Option is being exercised,
and such other representations and agreements as to the holder’s investment intent with respect to such Shares as may be
required by the Company pursuant to the provisions of the Plan. Such written notice shall be signed by Optionee and shall be delivered
to the Company by such means as are determined by the Company in its discretion to constitute adequate delivery. The written notice
shall be accompanied by payment of the aggregate Exercise Price for the purchased Shares.


 


(ii) As
a condition to the exercise of this Option and as further set forth in the Plan, Optionee agrees to make adequate provision for
federal, state or other applicable tax, withholding, required deductions or other payments, if any, which arise upon the grant,
vesting or exercise of this Option, or disposition of Shares, whether by withholding, direct payment to the Company, or otherwise,
as determined by the Company in its sole discretion.


 


(iii) The
Company is not obligated, and will have no liability for failure, to issue or deliver any Shares upon exercise of this Option unless
such issuance or delivery would comply with any applicable laws, with such compliance determined by the Company in consultation
with its legal counsel. This Option may not be exercised until such time as the Plan has been approved by the holders of capital
stock of the Company, or if the issuance of such Shares upon such exercise or the method of payment of consideration for such Shares
would constitute a violation of any applicable laws, including any applicable U.S. federal or state or foreign securities laws
or any other law or regulation, including any rule under Part 221 of Title 12 of the Code of Federal Regulations as promulgated
by the Federal Reserve Board, or the requirements of any stock exchange or market system upon which the Shares may then be listed.
As a condition to the exercise of this Option, the Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable laws. Assuming such compliance, for income tax purposes the Shares shall be considered
transferred to Optionee on the date on which this Option is exercised with respect to such Shares.


 


(iv) Subject
to compliance with all applicable laws, this Option shall be deemed to be exercised upon receipt by the Company of the appropriate
written notice of exercise accompanied by the Exercise Price and the satisfaction of any applicable obligations described in Section
3(b)(ii) above.


 


4. Method
of Payment. Unless otherwise specified by the Company in its sole discretion to comply with Applicable Laws or facilitate the
administration of the Plan, payment of the Exercise Price shall be in any form authorized by the terms of the Plan.


 


Optionee
understands and agrees that, if required by the Company or Applicable Laws, any cross-border cash remittance made to exercise
this Option or transfer proceeds received upon the sale of Shares must be made through a locally authorized financial
institution or registered foreign exchange agency and may require Optionee to provide to such entity certain information
regarding the transaction. Moreover, Optionee understands and agrees that the future value of the underlying Shares is
unknown and cannot be predicted with certainty and may decrease in value, even below the Exercise Price. Optionee understands
that neither the Company nor any Subsidiary Corporations or affiliate is responsible for any foreign exchange fluctuation
between local currency and the United States Dollar or the selection by the Company or any Subsidiary Corporations or
affiliate in its sole discretion of an applicable foreign currency exchange rate that may affect the value of the Option (or
the calculation of income or tax-related items thereunder).

other period of time as is set forth in the Notice.


 


(c) Death
of Optionee. In the event of termination of Optionee’s Service as a result of Optionee’s death, or in the event

or other person who acquired the right to exercise the Option by reason of the Optionee’s death at any time prior to the
expiration of the Option Expiration Date or such other period of time as is set forth in the Notice.


 


(d) Termination
for Cause. In the event of termination of Optionee’s Service for Cause, the Option (including any vested portion thereof)

Company’s securities registered under the Securities Act of 1933, as amended, Optionee shall not sell, make any short
sale of, loan, grant any option for the purchase of, or otherwise dispose of any securities of the Company however or
whenever acquired (except for those being registered) without the prior written consent of the Company or such underwriters,
as the case may be, for 180 days from the effective date of the registration statement, plus such additional period, to the
extent required by FINRA rules, up to a maximum of 216 days from the effective date of the registration statement, and
Optionee shall execute an agreement reflecting the foregoing as may be requested by the underwriters at the time of such
offering.


 


8. Effect
of Agreement. Optionee acknowledges receipt of a copy of the Plan and represents that he or she is familiar with the terms
and provisions thereof (and has had an opportunity to consult counsel regarding the Option terms), and hereby accepts this Option
and agrees to be bound by its contractual terms as set forth herein and in the Plan. Optionee hereby agrees to accept as binding,
conclusive and final all decisions and interpretations of the Administrator regarding any questions relating to this Option. In
the event of a conflict between the terms and provisions of the Plan and the terms and provisions of the Notice and this Agreement,
the Plan terms and provisions shall prevail.


 


9. Imposition
of Other Requirements. The Company reserves the right to impose other requirements on Optionee’s participation in the
Plan, on the Option and on any award or Shares acquired under the Plan, to the extent the Company determines it is necessary or
advisable in order to comply with any applicable laws or facilitate the administration of the Plan. Optionee agrees to sign any
additional agreements or undertakings that may be necessary to accomplish the foregoing. Furthermore, Optionee acknowledges that
the laws of the country in which Optionee is working at the time of grant, vesting and exercise of the Option or the sale of Shares
received pursuant to this Agreement (including any rules or regulations governing securities, foreign exchange, tax, labor, or
other matters) may subject Optionee to additional procedural or regulatory requirements that Optionee is and will be solely responsible
for and must fulfill.


 


10. Electronic
Delivery. The Company may, in its sole discretion, decide to deliver any documents related to Optionee’s current or future
participation in the Plan by electronic means or to request Optionee’s consent to participate in the Plan by electronic means.
Optionee hereby consents to receive such documents by electronic delivery and agrees to participate in the Plan through an on-line
or electronic system established and maintained by the Company or a third party designated by the Company.


 


11. Unvested
Share Repurchase Option.


 


(a) Grant
of Unvested Share Repurchase Option. In the event the Optionee’s Service is terminated for any reason or no reason,
with or without cause, or, if the Optionee, the Optionee’s legal representative, or other holder of shares acquired pursuant
to this Agreement, attempts to sell, exchange, transfer, pledge, or otherwise dispose of (other than pursuant to an Ownership Change
Event) any Unvested Shares, as defined in Section 11(b) below, the Company shall have the right to repurchase the Unvested Shares
under the terms and subject to the conditions set forth in this Section 11 (the “Unvested Share Repurchase Option”).


 


(b) Unvested
Shares Defined. The “Unvested
Shares” shall mean, on any given date, the number of Shares acquired upon exercise of the Option which exceed
the vested portion determined as of such date.


 






    26


     


    

 


(c) Exercise
of Unvested Share Repurchase Option. The
Company may exercise the Unvested Share Repurchase Option by written notice to the Optionee within sixty (60) days after (a) termination
of the Optionee’s Service or (b) the Company has received notice of the attempted disposition of Unvested Shares. If the
Company fails to give notice within such sixty (60) day period, the Unvested Share Repurchase Option shall terminate unless the
Company and the Optionee have extended the time for the exercise of the Unvested Share Repurchase Option. The Unvested Share Repurchase
Option must be exercised, if at all, for all of the Unvested Shares, except as the Company and the Optionee otherwise agree.


 


(d) Payment
for Shares and Return of Shares to Company. The
purchase price per share being repurchased by the Company shall be an amount equal to the Optionee’s original cost per share,
as adjusted for stock splits, stock dividends and the like (the “Repurchase Price”). The Company
shall pay the aggregate Repurchase Price to the Optionee in cash within thirty (30) days after the date of the written notice to
the Optionee of the Company’s exercise of the Unvested Share Repurchase Option. For purposes of the foregoing, cancellation
of any purchase money indebtedness of the Optionee to any Participating Company for the shares shall be treated as payment to the
Optionee in cash to the extent of the unpaid principal and any accrued interest canceled. The shares being repurchased shall be
delivered to the Company by the Optionee at the same time as the delivery of the Repurchase Price to the Optionee.


 


(e) Assignment
of Unvested Share Repurchase Option. The
Company shall have the right to assign the Unvested Share Repurchase Option at any time, whether or not such option is then exercisable,
to one or more persons as may be selected by the Company.


 


(f) Ownership
Change Event. Upon the occurrence of
an Ownership Change Event, any and all new, substituted or additional securities or other property to which the Optionee is entitled
by reason of the Optionee’s ownership of Unvested Shares shall be immediately subject to the Unvested Share Repurchase Option
and included in the terms “Shares” and “Unvested Shares” for all purposes of the Unvested Share Repurchase
Option with the same force and effect as the Unvested Shares immediately prior to the Ownership Change Event. While the aggregate
Repurchase Price shall remain the same after such Ownership Change Event, the Repurchase Price per Unvested Share upon exercise
of the Unvested Share Repurchase Option following such Ownership Change Event shall be adjusted as appropriate.


 


(g)
Election under Section 83(b) of the Code. If the Optionee exercises this Option to purchase Shares are both
nontransferable and subject to the Company’s Unvested Share Repurchase Option, which constitutes a substantial risk of
forfeiture, the Optionee understands that the Optionee should consult with the Optionee’s tax advisor regarding the
advisability of filing with the Internal Revenue Service an election under Section 83(b) of the Code, which must be filed no
later than thirty (30) days after the date on which the Optionee exercises the Option. Shares acquired upon exercise of the
Option are nontransferable and subject to a substantial risk of forfeiture if they are unvested and are subject to a right of
the Company to repurchase such shares at the Optionee’s original purchase price if the Optionee’s Service
terminates. Failure to file an election under Section 83(b), if appropriate, may result in adverse tax consequences to the
Optionee. However, an election under Section 83(b) may, under certain circumstances, result in adverse tax consequences to
the Optionee. The Optionee acknowledges that the Optionee has been advised to consult with a tax advisor prior to the
exercise of the Option regarding the tax consequences to the Optionee of the exercise of the Option and the effect of filing
or not filing an election under Section 83(b). AN ELECTION UNDER SECTION 83(b) MUST BE FILED, IF AT ALL, WITHIN 30 DAYS AFTER
THE DATE ON WHICH THE OPTIONEE PURCHASES SHARES. THIS TIME PERIOD CANNOT BE EXTENDED. THE OPTIONEE ACKNOWLEDGES THAT TIMELY
FILING OF A SECTION 83(b) ELECTION, IF APPROPRIATE, IS THE OPTIONEE’S SOLE RESPONSIBILITY, EVEN IF THE OPTIONEE
REQUESTS THE COMPANY OR ITS REPRESENTATIVE TO FILE SUCH ELECTION ON HIS OR HER BEHALF.

GRID DYNAMICS INTERNATIONAL,
INC.


 


EARLY EXERCISE NOTICE
AND RESTRICTED STOCK PURCHASE AGREEMENT


 


This Agreement
(“Agreement”) is made as of____________ by and between Grid Dynamics International, Inc., a California
corporation (the “Company”), and_____________________ (“Purchaser”). To the extent any capitalized
terms used in this Agreement are not defined, they shall have the meaning ascribed to them in the Company’s 2018 Stock Plan
(the “Plan”) and the Option Agreement (as defined below).


 


1. Exercise of
Option. Subject to the terms and conditions hereof, Purchaser hereby elects to exercise his or her option to purchase
shares of the Common Stock (the “Shares”) of the Company under and pursuant to the Plan, the Notice of
Stock Option Grant and the Stock Option Agreement granted____________________ (the “Option Agreement”). Of
these Shares, Purchaser has elected to purchase_______________________ of those Shares which have become vested as of the
date hereof under the Vesting/Exercise Schedule set forth in the Notice of Stock Option Grant (the “Vested
Shares”) and Shares which have not yet vested under such Vesting/Exercise Schedule (the “Unvested
Shares”). The purchase price for the Shares shall be $___________ per Share for a total purchase price of $ The term “Shares” refers to the purchased Shares and all securities received in connection with the Shares
pursuant to stock dividends or splits, all securities received in replacement of the Shares in a recapitalization, merger,
reorganization, exchange or the like, and all new, substituted or additional securities or other properties to which
Purchaser is entitled by reason of Purchaser’s ownership of the Shares. The Vested Shares and the Unvested Shares are
entitled to the same rights as shares of the Company’s Common Stock, including rights to receive dividends or other
distributions to shareholders as well as the right to vote the Vested Shares and Unvested Shares.


 


2. Time
and Place of Exercise; Section 83(b) Election.


 


(a) The
purchase and sale of the Shares under this Agreement shall occur at the principal office of the Company simultaneously with
the execution and delivery of this Agreement, the payment of the aggregate exercise price by any method listed in Section 3
of the Option Agreement, and the satisfaction of any applicable tax, withholding, required deductions or other payments, all
in accordance with the provisions of Section 2(b) of the Option Agreement. The Company shall issue the Shares to Purchaser by
entering such Shares in Purchaser’s name as of such date in the books and records of the Company or, if applicable, a
duly authorized transfer agent of the Company, against payment of the exercise price therefor by Purchaser. If applicable,
the Company will deliver to Purchaser a certificate representing the Shares as soon as practicable following such date.


 


(b)
Purchaser understands that Purchaser may elect to be taxed at the time the Unvested Shares are purchased, rather than when
and as the Repurchase Option expires, by filing an election under Section 83(b) (an "83(b) Election ") of the
Internal Revenue Code of 1986, as amended (the "Code"), with the Internal Revenue Service within 30 days from the
date of purchase. Even if the fair market value of the Unvested Shares at the time of the execution of this Agreement equals
the amount paid for the Unvested Shares, the election must be made to avoid income tax treatment under Section 83(a) in the
future. Purchaser understands that failure to file such an election in a timely manner may result in adverse tax consequences
for Purchaser. Purchaser further understands that an additional copy of such election form should be filed with his federal
income tax return for the calendar year in which the date of this Agreement falls. Purchaser acknowledges that the foregoing
is only a summary of the effect of United States federal income taxation with respect to purchase of the Unvested Shares
hereunder, and does not purport to be complete.


 






    29


     


    

 


Purchaser
further agrees that he will execute and file a copy of the 83(b) Election attached hereto as Attachment A (for tax purposes in
connection with the early exercise of an option) within 30 days from the date of exercise.


 


3. Limitations
on Transfer. In addition to any other limitation on transfer created by any applicable laws, Purchaser shall not assign, encumber
or dispose of any interest in the Shares while the Shares are subject to the Company’s Repurchase Option (as defined below).
After any Shares have been released from such Repurchase Option, Purchaser shall not assign, encumber or dispose of any interest
in such Shares except in compliance with the provisions below and any applicable laws.


 


(a) Repurchase
Option.


 


(i) In
the event of the voluntary or involuntary termination of Purchaser’s Continuous Service Status with the Company for any reason
(including death or Disability), with or without Cause, the Company shall upon the date of such termination (the “Termination
Date”) have an irrevocable, exclusive option (the “Repurchase Option”) for a period of sixty (60)
days from such date to repurchase all or any portion of the Unvested Shares (as defined below) held by Purchaser as of the Termination
Date at the original purchase price per Share (adjusted for any stock splits, stock dividends and the like) specified in Section
1. As used herein, “Unvested Shares” means Shares that have not yet been released from the Repurchase Option.


 


(ii)
Unless the Company notifies Purchaser within sixty (60) days from the Termination Date that it does not intend to exercise
its Repurchase Option with respect to some or all of the Unvested Shares, the Repurchase Option shall be deemed automatically
exercised by the Company as of the end of such sixty (60) day period following such termination, provided that the Company
may notify Purchaser that it is exercising its Repurchase Option as of a date prior to the end of such sixty (60) day period.
Unless Purchaser is otherwise notified by the Company pursuant to the preceding sentence that the Company does not intend to
exercise its Repurchase Option as to some or all of the Unvested Shares to which it applies at the time of termination,
execution of this Agreement by Purchaser constitutes written notice to Purchaser of the Company’s intention to exercise
its Repurchase Option with respect to all Unvested Shares to which such Repurchase Option applies. The Company, at its
choice, may satisfy its payment obligation to Purchaser with respect to exercise of the Repurchase Option by either(A)
delivering a check to Purchaser in the amount of the purchase price for the Unvested Shares being repurchased, or (B) in the
event Purchaser is indebted to the Company, canceling an amount of such indebtedness equal to the purchase price for the
Unvested Shares being repurchased, or (C) by a combination of (A) and (B) so that the combined payment and cancellation of
indebtedness equals such purchase price. In the event of any deemed automatic exercise of the Repurchase Option pursuant to
this Section 3(a)(ii) in which Purchaser is indebted to the Company, such indebtedness equal to the purchase price of the
Unvested Shares being repurchased shall be deemed automatically canceled as of the end of such sixty (60) day period
following termination of Purchaser’s employment or consulting relationship unless the Company otherwise satisfies its
payment obligations. As a result of any repurchase of Unvested Shares pursuant to this Section 3(a), the Company shall become
the legal and beneficial owner of the Unvested Shares being repurchased and shall have all rights and interest therein or
related thereto, and the Company shall have the right to transfer to its own name the number of Unvested Shares being
repurchased by the Company, without further action by Purchaser.


 






    30


     


    

 


(iii) One
hundred percent (100%) of the Shares shall initially be subject to the Repurchase Option. The Unvested Shares shall be released
from the Repurchase Option in accordance with the Vesting/Exercise Schedule set forth in the Notice of Stock Option Grant until
all Shares are released from the Repurchase Option. Fractional shares shall be rounded to the nearest whole share.


 


(b) Right
of First Refusal. Before any Shares held by Purchaser or any transferee of Purchaser (either being sometimes referred to herein
as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of law), the
Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions set forth in
this Section 3(b) (the “Right of First Refusal”).


 


(i) Notice
of Proposed Transfer. The Holder of the Shares shall deliver to the Company a notice (the “Notice”) stating:
(A) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (B) the name of each proposed purchaser or
other transferee (“Proposed Transferee”); (C) the number of Shares to be transferred to each Proposed Transferee;
and (D) the terms and conditions of each proposed sale or transfer, including (without limitation) the purchase price for such
Shares (the “Purchase Price”). The Holder shall offer the Shares at the Purchase Price and upon the same terms
(or terms as similar as reasonably possible) to the Company or its assignee(s).


 


(ii) Exercise
of Right of First Refusal. At any time within 30 days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase any or all of the Shares proposed to be transferred to any one or more
of the Proposed Transferees, at the Purchase Price. If the Purchase Price includes consideration other than cash, the cash equivalent
value of the non-cash consideration shall be determined by the Board in good faith.


 


(iii) Payment.
Payment of the Purchase Price shall be made, at the election of the Company or its assignee(s), in cash (by check), by cancellation
of all or a portion of any outstanding indebtedness, or by any combination thereof within 60 days after receipt of the Notice or
in the manner and at the times set forth in the Notice, unless otherwise restricted pursuant to the Option Agreement.


 


(iv)
Holder’s Right to Transfer. If any of the Shares proposed in the Notice to be transferred to a given Proposed
Transferee are not purchased by the Company and/or its assignee(s) as provided in this Section 3 (b), then the Holder may
sell or otherwise transfer any unpurchased Shares to that Proposed Transferee at the Purchase Price or at a higher price,
provided that such sale or other transfer is consummated within 120 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any Applicable Laws and the Proposed Transferee agrees in
writing that the provisions of this Section 3 and the waiver of statutory information rights in Section 9 shall continue to
apply to the Shares in the hands of such Proposed Transferee. The Company, in consultation with its legal counsel, may
require the Holder to provide an opinion of counsel evidencing compliance with Applicable Laws. If the Shares described in
the Notice are not transferred to the Proposed Transferee within such period, or if the Holder proposes to change the price
or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given to the Company, and the
Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by the Holder may be
sold or otherwise transferred.


 






    31


     


    

 


(v) Exception
for Certain Family Transfers. Anything to the contrary contained in this Section 3(b) notwithstanding, the transfer of any
or all of the Shares during Holder’s lifetime or on Holder’s death by will or intestacy to Holder’s Immediate
Family or a trust for the benefit of Holder’s Immediate Family shall be exempt from the provisions of this Section 3(b).
“Immediate Family” as used herein shall mean Holder themselves, lineal descendant or antecedent, spouse (or
spouse’s antecedents), father, mother, brother or sister (or their descendants), stepchild (or their antecedents or descendants),
aunt or uncle (or their antecedents or descendants), brother-in-law or sister-in-law (or their antecedents or descendants) and
shall include adoptive relationships. In such case, the transferee or other recipient shall receive and hold the Shares so transferred
subject to the provisions of this Section 3, and there shall be no further transfer of such Shares except in accordance with the
terms of this Section 3.


 


(c) Company’s
Right to Purchase upon Involuntary Transfer. In the event, at any time after the date of this Agreement, of any transfer by
operation of law or other involuntary transfer (including death or divorce, but excluding a transfer to Immediate Family as set
forth in Section 3(b)(v) above) of all or a portion of the Shares by the record holder thereof, the Company shall have an option
to purchase any or all of the Shares transferred at the greater of the purchase price paid by Purchaser pursuant to this Agreement
or the Fair Market Value of the Shares on the date of transfer (as determined by the Company). Upon such a transfer, the Holder
shall promptly notify the Secretary of the Company of such transfer. The right to purchase such Shares shall be provided to the
Company for a period of 30 days following receipt by the Company of notice from the Holder.


 


(d) Assignment.
The right of the Company to purchase any part of the Shares may be assigned in whole or in part to any shareholder or shareholders
of the Company or other persons or organizations.


 


(e) Restrictions
Binding on Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject
to the provisions of this Agreement and the terms of the Option Agreement, including Section 6 of the Option Agreement and, insofar
as applicable, the Repurchase Option. In the event of any purchase by the Company hereunder where the Shares or interest are held
by a transferee, the transferee shall be obligated, if requested by the Company, to transfer the Shares or interest to the Purchaser
for consideration equal to the amount to be paid by the Company hereunder. In the event the Repurchase Option is deemed exercised
by the Company pursuant to Section 3 (a)(ii) hereof, the Company may deem any transferee to have transferred the Shares or interest
to Purchaser prior to their purchase by the Company, and payment of the purchase price by the Company to such transferee shall
be deemed to satisfy Purchaser’s obligation to pay such transferee for such Shares or interest, and also to satisfy the Company’s
obligation to pay Purchaser for such Shares or interest. Any sale or transfer of the Shares shall be void unless the provisions
of this Agreement are satisfied.


 






    32


     


    

(f) Termination
of Rights. The Right of First Refusal granted the Company by Section 3(b) above and the option to repurchase the Shares in
the event of an involuntary transfer granted the Company by Section 3(c) above shall terminate upon the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and
Exchange Commission under the Securities Act of 1933, as amended (the “Securities Act”). Upon termination of
such transfer restrictions, the Company will remove any stop-transfer notices referred to in Section 6(b) below and related to
the restrictions in this Section 3 and, if certificates are issued, a new certificate or certificates representing the Shares not
repurchased shall be issued, on request, without the legend referred to in Section 6(a)(ii) below and delivered to Holder.


 


4. Escrow
of Unvested Shares. For purposes of facilitating the enforcement of the provisions of Section 3 above, Purchaser agrees, immediately
upon receipt of the certificate(s) for the Shares subject to the Repurchase Option, to deliver such certificate(s), together with
an Assignment Separate from Certificate in the form attached to this Agreement as Attachment B executed by Purchaser and
by Purchaser’s spouse (if required for transfer), in blank, to the Secretary of the Company, or the Secretary’s designee,
to hold such certificate(s) and Assignment Separate from Certificate in escrow and to take all such actions and to effectuate all
such transfers and/or releases as are in accordance with the terms of this Agreement. Purchaser hereby acknowledges that the Secretary
of the Company, or the Secretary’s designee, is so appointed as the escrow holder with the foregoing authorities as a material
inducement to make this Agreement and that said appointment is coupled with an interest and is accordingly irrevocable. Purchaser
agrees that said escrow holder shall not be liable to any party hereof (or to any other party). The escrow holder may rely upon
any letter, notice or other document executed by any signature purported to be genuine and may resign at any time. Purchaser agrees
that if the Secretary of the Company, or the Secretary’s designee, resigns as escrow holder for any or no reason, the Board
shall have the power to appoint a successor to serve as escrow holder pursuant to the terms of this Agreement.


 


5. Investment
and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the following:


 


(a) Purchaser
is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing the Shares for investment for Purchaser’s
own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning
of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer
the Shares to any other person or entity.


 


(b) Purchaser
understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein.


 


(c) Purchaser
further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the
Company is under no obligation to register the securities.


 






    33


     


    

 


(d) Purchaser
is familiar with the provisions of Rule 144, promulgated under the Securities Act, which, in substance, permits limited public
resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate
of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company
provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144, which rule
requires, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934,
as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified
time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to
brokered transactions. Notwithstanding this Section 5(d), Purchaser acknowledges and agrees to the restrictions set forth in Section
5(e) below.


 


(e) Purchaser
further understands that in the event all of the applicable requirements of Rule 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration exemption will be required; and that, notwithstanding
the fact that Rule 144 is not exclusive, the Staff of the Securities and Exchange Commission has expressed its opinion that persons
proposing to sell private placement securities other than in a registered offering and otherwise than pursuant to Rule 144 will
have a substantial burden of proof in establishing that an exemption from registration is available for such offers or sales, and
that such persons and their respective brokers who participate in such transactions do so at their own risk.


 


(f) Purchaser
understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or disposition of the
Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the
purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax advice.


 


6. Restrictive
Legends and Stop-Transfer Orders.


 


(a) Legends.
Any certificate or certificates representing the Shares shall bear the following legends (as well as any legends required by the
Company or applicable state and federal corporate and securities laws):


 


(i) “THE
SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT
AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT
AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION
IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933


 






    34


     


    

(ii) “THE
SHARES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY
AND THE SHAREHOLDER, A COPY OF WHICH IS ON FILE WITH AND MAY BE OBTAINED FROM THE SECRETARY OF THE COMPANY AT NO CHARGE.’


 


(b) Stop-Transfer
Notices. Purchaser agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue
appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own
securities, it may make appropriate notations to the same effect in its own records.


 


(c) Refusal
to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote
or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.


 


7. No
Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever any right with respect to continuation of
an employment or consulting relationship with the Company (any parent, subsidiary or affiliate), nor shall it interfere in any
way with such employee’s or consultant’s right or the Company’s (parent’s, subsidiary’s or affiliate’s)
right to terminate his or her employment or consulting relationship at any time, with or without cause.


 


8. Lock-Up
Agreement. The lock-up provisions set forth in Section 6 of the Option Agreement shall apply to the Shares issued upon exercise
of the Option hereunder and Purchaser reaffirms Purchaser’s obligations set forth therein.


 


9. Waiver
of Statutory Information Rights. Optionee acknowledges and understands that, but for the waiver made herein, Optionee would
be entitled, upon written demand stating the purpose thereof, to inspect for any proper purpose the accounting books and records
and minutes of proceedings of the shareholders and the board and committees of the board, and such books and records of subsidiaries
of the Company, if any, under the circumstances and in the manner provided in Section 1601 of the General Corporation Law of California
(any and all such rights, and any and all such other rights of Optionee as may be provided for in Section 1601, the “Inspection
Rights”). In light of the foregoing, until the first sale of Common Stock of the Company to the general public pursuant
to a registration statement filed with and declared effective by the Securities and Exchange Commission under the Securities Act
of 1933, as amended, Optionee hereby unconditionally and irrevocably waives the Inspection Rights, whether such Inspection Rights
would be exercised or pursued directly or indirectly pursuant to Section 1601 or otherwise, and covenants and agrees never to directly
or indirectly commence, voluntarily aid in any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause
of action, or other proceeding to pursue or exercise the Inspection Rights. The foregoing waiver applies to the Inspection Rights
of Optionee in Optionee’s capacity as a shareholder and shall not affect any rights of a director, in his or her capacity
as such, under Section 1601. The foregoing waiver shall not apply to any contractual inspection rights of Optionee under any written
agreement with the Company.


 






    35


     


    

 


10. Miscellaneous.


 







(a) Governing
Law. This Agreement and all acts and transactions pursuant hereto and the rights and obligations of the parties hereto shall
be governed, construed and interpreted in accordance with the laws of the State of California, without giving effect to principles
of conflicts of law. For purposes of litigating any dispute that may arise directly or indirectly from this Agreement, the parties
hereby submit and consent to the exclusive jurisdiction of the State of California and agree that any such litigation shall be
conducted only in the courts of Contra Costa County, California, or the federal courts of the United States located in Contra Costa
County, California, and no other courts.


 


(b) Entire
Agreement; Enforcement of Rights. This Agreement, together with the Option Agreement and the Plan, sets forth the entire agreement
and understanding of the parties relating to the subject matter herein and merges all prior or contemporaneous discussions between
them. No modification of or amendment to this Agreement, nor any waiver of any rights under this Agreement, shall be effective
unless in writing signed by the parties to this Agreement. The failure by either party to enforce any rights under this Agreement
shall not be construed as a waiver of any rights of such party.


 


(c) Severability.
If one or more provisions of this Agreement are held to be unenforceable under Applicable Laws, the parties agree to renegotiate
such provision in good faith. In the event that the parties cannot reach a mutually agreeable and enforceable replacement for such
provision, then (i) such provision shall be excluded from this Agreement, (ii) the balance of the Agreement shall be interpreted
as if such provision were so excluded and (iii) the balance of the Agreement shall be enforceable in accordance with its terms.


 


(d) Notices.
Any notice required or permitted by this Agreement shall be in writing and shall be deemed sufficient when delivered personally
or by overnight courier or sent by email or fax (upon customary confirmation of receipt), or forty-eight (48) hours after being

successors and assigns. The rights and obligations of Purchaser under this Agreement may only be assigned with the prior written
consent of the Company.

EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105 OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO

EXHIBIT B

GRID DYNAMICS INTERNATIONAL, INC.

2018 STOCK PLAN

EXERCISE AGREEMENT 


 


This
Exercise Agreement (this “Agreement”) is made as of_________________ by and between Grid Dynamics
International, Inc., a California corporation (the “Company”), and___________________
(“Purchaser”). To the extent any capitalized terms used in this Agreement are not defined, they shall have
the meaning ascribed to them in the Company’s 2018 Stock Plan (the “Plan”) and the Option Agreement
(as defined below).


 


1.
Exercise of Option. Subject to the terms and conditions hereof, Purchaser hereby elects to exercise his or her option to
purchase ______________________ shares of the Common Stock (the “Shares”) of the Company under and
pursuant to the Plan, the Notice of Stock Option Grant and the Stock Option Agreement granted ______________________ (the
“Option Agreement”). The purchase price for the Shares shall be $_____________ per Share for a total
purchase price of $______________ . The term “Shares” refers to the purchased Shares and all securities
received in connection with the Shares pursuant to stock dividends or splits, all securities received in replacement of the
Shares in a recapitalization, merger, reorganization, exchange or the like, and all new, substituted or additional securities
or other property to which Purchaser is entitled by reason of Purchaser’s ownership of the Shares. To the extent the
Option Agreement permits the exercise of Unvested Shares (as defined in the Option Agreement) and Purchaser elects to
purchase such unvested Shares, then such Unvested Shares shall be subject to repurchase in accordance with Section 11 of the
Option Agreement. The vested Shares and the Unvested Shares are entitled to the same rights as shares of the Company’s
Common Stock, including rights to receive dividends or other distributions to shareholders as well as the right to vote the
vested Shares and Unvested Shares.


 


2. Time
and Place of Exercise. The purchase and sale of the Shares under this Agreement shall occur at the principal office of the
Company simultaneously with the execution and delivery of this Agreement, the payment of the aggregate exercise price by any method
listed in Section 3 of the Option Agreement, and the satisfaction of any applicable tax, withholding, required deductions or other
payments, all in accordance with the provisions of Section 2(b) of the Option Agreement. The Company shall issue the Shares to
Purchaser by entering such Shares in Purchaser’s name as of such date in the books and records of the Company or, if applicable,
a duly authorized transfer agent of the Company, against payment of the exercise price therefor by Purchaser. If applicable, the
Company will deliver to Purchaser a certificate representing the Shares as soon as practicable following such date.


 






    41


     


    

 


3. Limitations
on Transfer. In addition to any other limitation on transfer created by Applicable Laws, Purchaser shall not assign, encumber
or dispose of any interest in the Shares except in compliance with the provisions below and Applicable Laws.


 


(a) Right
of First Refusal. Before any Shares held by Purchaser or any transferee of Purchaser (either being sometimes referred to
herein as the “Holder”) may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to purchase the Shares on the terms and conditions
set forth in this Section 3(a) (the “Right of First Refusal”).


 


(i) Notice
of Proposed Transfer. The Holder of the Shares shall deliver to the Company a written notice (the “Notice”)
stating: (A) the Holder’s bona fide intention to sell or otherwise transfer such Shares; (B) the name of each proposed purchaser
or other transferee (“Proposed Transferee”); (C) the number of Shares to be transferred to each Proposed Transferee;
and (D) the terms and conditions of each proposed sale or transfer, including (without limitation) the purchase price for such
Shares (the “Purchase Price”). The Holder shall offer the Shares at the Purchase Price and upon the same terms
(or terms as similar as reasonably possible) to the Company or its assignee(s).


 


(ii) Exercise
of Right of First Refusal. At any time within 30 days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all or none of the Shares proposed to be transferred to any one or more
of the Proposed Transferees, at the Purchase Price. If the Purchase Price includes consideration other than cash, the cash equivalent
value of the non-cash consideration shall be determined by the Board in good faith.


 


(iii) Payment.
Payment of the Purchase Price shall be made, at the election of the Company or its assignee(s), in cash (by check), by cancellation
of all or a portion of any outstanding indebtedness, or by any combination thereof within 60 days after receipt of the Notice or
in the manner and at the times set forth in the Notice unless otherwise restricted pursuant to the Option Agreement.


 


(iv) Holder’s
Right to Transfer. If any of the Shares proposed in the Notice to be transferred to a given Proposed Transferee are not purchased
by the Company and/or its assignee(s) as provided in this Section 3(a), then the Holder may sell or otherwise transfer any unpurchased
Shares to that Proposed Transferee at the Purchase Price or at a higher price, provided that such sale or other transfer is consummated
within 120 days after the date of the Notice and provided further that any such sale or other transfer is effected in accordance
with any Applicable Laws and the Proposed Transferee agrees in writing that the provisions of this Section 3 and the waiver of
statutory information rights in Section 8 shall continue to apply to the Shares in the hands of such Proposed Transferee. The Company,
in consultation with its legal counsel, may require the Holder to provide an opinion of counsel evidencing compliance with Applicable
Laws. If the Shares described in the Notice are not transferred to the Proposed Transferee within such period, or if the Holder
proposes to change the price or other terms to make them more favorable to the Proposed Transferee, a new Notice shall be given
to the Company, and the Company and/or its assignees shall again be offered the Right of First Refusal before any Shares held by
the Holder may be sold or otherwise transferred.


 


(v)
Exception for Certain Family Transfers. Anything to the contrary contained in this Section 3(a) notwithstanding, the
transfer of any or all of the Shares during Holder’s lifetime or on Holder’s death by will or intestacy to
Holder’s Immediate Family or a trust for the benefit of Holder’s Immediate Family shall be exempt from the
provisions of this Section 3(a). “Immediate Family” as used herein shall mean Holder themselves, lineal
descendant or antecedent, spouse (or spouse’s antecedents), father, mother, brother or sister (or their descendants),
stepchild (or their antecedents or descendants), aunt or uncle (or their antecedents or descendants), brother-in-law or
sister-in-law (or their antecedents or descendants) and shall include adoptive relationships. In such case, the transferee or
other recipient shall receive and hold the Shares so transferred subject to the provisions of this Section 3, and there shall
be no further transfer of such Shares except in accordance with the terms of this Section 3.


 






    42


     


    

 


(b) Company’s
Right to Purchase upon Involuntary Transfer. In the event of any transfer by operation of law or other involuntary transfer
(including death or divorce, but excluding a transfer to Immediate Family as set forth in Section 3(a)(v) above) of all or a portion
of the Shares by the record holder thereof, the Company shall have an option to purchase any or all of the Shares transferred at
the greater of the purchase price paid by Purchaser pursuant to this Agreement or the Fair Market Value of the Shares on the date
of transfer (as determined by the Company). Upon such a transfer, the Holder shall promptly notify the Secretary of the Company
of such transfer. The right to purchase such Shares shall be provided to the Company for a period of 30 days following receipt
by the Company of written notice from the Holder.


 


(c) Assignment.
The right of the Company to purchase any part of the Shares may be assigned in whole or in part to any holder or holders of capital
stock of the Company or other persons or organizations.


 


(d) Restrictions
Binding on Transferees. All transferees of Shares or any interest therein will receive and hold such Shares or interest subject
to the provisions of this Agreement and the terms of the Option Agreement, including, without limitation, Section 7 of the Option
Agreement. Any sale or transfer of the Shares shall be void unless the provisions of this Agreement are satisfied.


 


(e) Termination
of Rights. The Right of First Refusal granted the Company by Section 3(a) above and the option to repurchase the Shares in
the event of an involuntary transfer granted the Company by Section 3(b) above shall terminate upon the first sale of Common Stock
of the Company to the general public pursuant to a registration statement filed with and declared effective by the Securities and
Exchange Commission under the Securities Act. Upon termination of such transfer restrictions, the Company will remove any stop-transfer
notices referred to in Section 5(b) below and related to the restrictions in this Section 3 and, if certificates are issued, a
new certificate or certificates representing the Shares not repurchased shall be issued, on request, without the legend referred
to in Section 5(a)(ii) below and delivered to Holder.


 


4. Investment
and Taxation Representations. In connection with the purchase of the Shares, Purchaser represents to the Company the following:


 


(a) Purchaser
is aware of the Company’s business affairs and financial condition and has acquired sufficient information about the Company
to reach an informed and knowledgeable decision to acquire the Shares. Purchaser is purchasing the Shares for investment for Purchaser’s
own account only and not with a view to, or for resale in connection with, any “distribution” thereof within the meaning
of the Securities Act or under any applicable provision of state law. Purchaser does not have any present intention to transfer
the Shares to any other person or entity.


 






    43


     


    

 


(b) Purchaser
understands that the Shares have not been registered under the Securities Act by reason of a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser’s investment intent as expressed herein.


 


(c) Purchaser
further acknowledges and understands that the securities must be held indefinitely unless they are subsequently registered under
the Securities Act or an exemption from such registration is available. Purchaser further acknowledges and understands that the
Company is under no obligation to register the securities.


 


(d) Purchaser
is familiar with the provisions of Rule 144, promulgated under the Securities Act, which, in substance, permits limited public
resale of “restricted securities” acquired, directly or indirectly, from the issuer of the securities (or from an affiliate
of such issuer), in a non-public offering subject to the satisfaction of certain conditions. Purchaser understands that the Company
provides no assurances as to whether he or she will be able to resell any or all of the Shares pursuant to Rule 144, which rule
requires, among other things, that the Company be subject to the reporting requirements of the Securities Exchange Act of 1934,
as amended, that resales of securities take place only after the holder of the Shares has held the Shares for certain specified
time periods, and under certain circumstances, that resales of securities be limited in volume and take place only pursuant to
brokered transactions. Notwithstanding this Section 4(d), Purchaser acknowledges and agrees to the restrictions set forth in Section
4(e) below.


 


(e) Purchaser
further understands that in the event all of the applicable requirements of Rule 144 are not satisfied, registration under the


Securities Act, compliance with Regulation
A, or some other registration exemption will be required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the Securities and Exchange Commission has expressed its opinion that persons proposing to sell private placement securities
other than in a registered offering and otherwise than pursuant to Rule 144 will have a substantial burden of proof in establishing
that an exemption from registration is available for such offers or sales, and that such persons and their respective brokers who
participate in such transactions do so at their own risk.


 


(f) Purchaser
understands that Purchaser may suffer adverse tax consequences as a result of Purchaser’s purchase or disposition of the
Shares. Purchaser represents that Purchaser has consulted any tax consultants Purchaser deems advisable in connection with the
purchase or disposition of the Shares and that Purchaser is not relying on the Company for any tax advice.


 






    44


     


    

 


5. Restrictive
Legends and Stop-Transfer Orders.


 


(a) Legends.
Any certificate or certificates representing the Shares shall bear the following legends (as well as any legends required by the
Company or applicable state and federal corporate and securities laws):


 







		i.	“THE SECURITIES REPRESENTED HEREBY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION
WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT
RELATED THERETO OR AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE
SECURITIES ACT OF 1933.”

MAY BE TRANSFERRED ONLY IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT BETWEEN THE COMPANY AND THE SHAREHOLDER, A COPY OF WHICH

(b) Stop-Transfer
Notices. Purchaser agrees that, in order to ensure compliance with the restrictions referred to herein, the Company may issue
appropriate “stop transfer” instructions to its transfer agent, if any, and that, if the Company transfers its own
securities, it may make appropriate notations to the same effect in its own records.


 


(c) Refusal
to Transfer. The Company shall not be required (i) to transfer on its books any Shares that have been sold or otherwise transferred
in violation of any of the provisions of this Agreement or (ii) to treat as owner of such Shares or to accord the right to vote
or pay dividends to any purchaser or other transferee to whom such Shares shall have been so transferred.


 


6. No
Employment Rights. Nothing in this Agreement shall affect in any manner whatsoever the right or power of the Company, or a
parent, subsidiary or affiliate of the Company, to terminate Purchaser’s employment or consulting relationship, for any reason,
with or without cause.

Waiver of Statutory Information Rights. Optionee acknowledges and understands that, but for the waiver made herein,
Optionee would be entitled, upon written demand stating the purpose thereof, to inspect for any proper purpose the accounting
books and records and minutes of proceedings of the shareholders and the board and committees of the board, and such books
and records of subsidiaries of the Company, if any, under the circumstances and in the manner provided in Section 1601 of the
General Corporation Law of California (any and all such rights, and any and all such other rights of Optionee as may be
provided for in Section 1601, the “Inspection Rights”). In light of the foregoing, until the first sale of
Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by
the Securities and Exchange Commission under the Securities Act of 1933, as amended, Optionee hereby unconditionally and
irrevocably waives the Inspection Rights, whether such Inspection Rights would be exercised or pursued directly or indirectly
pursuant to Section 1601 or otherwise, and covenants and agrees never to directly or indirectly commence, voluntarily aid in
any way, prosecute, assign, transfer, or cause to be commenced any claim, action, cause of action, or other proceeding to
pursue or exercise the Inspection Rights. The foregoing waiver applies to the Inspection Rights of Optionee in
Optionee’s capacity as a shareholder and shall not affect any rights of a director, in his or her capacity as such,
under Section 1601. The foregoing waiver shall not apply to any contractual inspection rights of Optionee under any written
agreement with the Company.
