WARRANT

 

THIS
WARRANT CERTIFICATE CERTIFIES THAT, for value received _______________________ or registered agents, is the registered holder
of a Warrant or Warrants expiring on a date which is five years from the date of the Company’s initial public offering of
units, of which this warrant (the “Warrant”) forms a part thereof, to purchase ___________ fully paid and non-assessable
shares (the “Shares”) of common stock, par value $0.00001 per share (the “Common Stock”),
of HANCOCK JAFFE LABORATORIES, INC., a Delaware corporation (the “Company”), for each Warrant evidenced by
this Warrant Certificate.

 

The
Warrant entitles the holder thereof to purchase from the Company, commencing upon consummation of the Company’s initial
public offering of this warrant, such number of Shares at the price of $[____]2 per whole share of Common Stock (the
“Warrant Price”), upon surrender of this Warrant Certificate with duly completed subscription form (see reverse)
(or, in the case of a Book-Entry Warrant Certificate, the Book-Entry Warrants to be exercised shown on the records of the Depository
to an account of the Warrant Agent at the Depository designated for such purpose in writing by the Warrant Agent to the Depository
from time to time),and payment of the Warrant Price at the office or agency of the Warrant Agent, VStock Transfer, LLC (such payment
to be made by check made payable to the Warrant Agent), but only subject to the conditions set forth herein and in the Warrant
Agreement between the Company and VStock Transfer, LLC. In no event shall the registered holder(s) of this Warrant be entitled
to receive a net-cash settlement, Shares or other consideration in lieu of physical settlement in Shares of the Company. The Warrant
Agreement provides that, upon the occurrence of certain events, the Warrant Price and the number of Warrant Shares purchasable
hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions. The term Warrant Price as used in this
Warrant Certificate refers to the price per Share at which Shares may be purchased at the time the Warrant is exercised.

 

This
Warrant will expire on the date first above written if it is not exercised prior to such date by the registered holder pursuant
to the terms of the Warrant Agreement or if it is not redeemed by the Company prior to such date.

 

No
fraction of a share of the Common Stock will be issued upon any exercise of a Warrant. If, upon exercise of a Warrant, a holder
would be entitled to receive a Share or Shares representing a fractional interest in a share of Common Stock, the Company will,
upon exercise, issue or cause to be issued only the largest whole number of Shares issuable on such exercise (and such fractional
remainders will be disregarded).

 

	 	 
	1Insert
    date five years from the date of closing of the initial public offering of the Units.
	2The
    exercise price shall be 120% of the initial public offering price per Unit.

 

    	 	 	 

    	 

    

 

Notwithstanding
anything to the contrary contained in the Warrant Agreement and herein, the number of Warrant Shares that may be acquired by the
registered holder upon any exercise of this Warrant (or otherwise in respect hereof) shall be limited to the extent necessary
to insure that, following such exercise (or other issuance), the total number of shares of Common Stock then beneficially owned
by such registered holder and its affiliates (as defined under the rules and regulations promulgated under the Securities Act
of 1933, as amended) and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with such
beneficial owner as a group for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended (“Beneficial
Ownership”), does not exceed [9.999]% of the total number of issued and outstanding shares of Common Stock (including
for such purpose the shares of Common Stock issuable upon such exercise), unless the registered holder’s Beneficial Ownership
already exceeds [9.999]%. For such purposes, Beneficial Ownership shall be determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder. This restriction may not be
waived. This provision shall not restrict the number of shares of Common Stock which a registered holder may receive or beneficially
own in order to determine the amount of securities or other consideration that such registered holder may receive in the event
of a Fundamental Transaction. “Fundamental Transaction” means any of the following: (i) the Company effects
any merger or consolidation of the Company with or into another person, (ii) the Company effects any sale of all or substantially
all of its assets in one or a series of related transactions, (iii) any tender offer or exchange offer (whether by the Company
or another person) is completed pursuant to which holders of Common Stock are permitted to tender or exchange their shares for
other securities, cash or property, or (iv) the Company effects any reclassification of the Common Stock or any compulsory share
exchange pursuant to which the Common Stock is effectively converted into or exchanged for other securities, cash or property.

 

Upon
any exercise of the Warrant for less than the total number of full Shares provided for herein, there shall be issued to the registered
holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Shares for which the Warrant has not been
exercised.

 

Warrant
Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by
attorney duly authorized in writing, may be exchanged in the manner and subject to the limitations provided in the Warrant Agreement,
but without payment of any service charge, for another Warrant Certificate or Warrant Certificates of like tenor and evidencing
in the aggregate a like number of Warrants.

 

Upon
due presentment for registration of transfer of the Warrant Certificate at the office or agency of the Warrant Agent, a new Warrant
Certificate or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to
the transferee(s) in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without
charge except for any applicable tax or other governmental charge.

 

The
Company and the Warrant Agent may deem and treat the registered holder(s) as the absolute owner(s) of this Warrant Certificate
(notwithstanding any notation of ownership or other writing hereon made by anyone) for the purpose of any exercise hereof, of
any distribution to the registered holder(s), and for all other purposes, and neither the Company nor the Warrant Agent shall
be affected by any notice to the contrary.

Jaffe Laboratories, Inc. sets forth herein the terms of its 2016 Omnibus Incentive Plan (as Amended and Restated Effective April
26, 2018), as follows:

 

	1.	PURPOSE

 

The
Plan is intended to enhance the ability of the Company and its Affiliates to attract and retain qualified officers, Non-employee
Directors, employees, consultants and advisors, and to motivate such individuals to serve the Company and its Affiliates and to
expend effort to improve the business results and earnings of the Company, by providing to such persons an opportunity to acquire
or increase a direct proprietary interest in the Company. To this end, the Plan provides for the grant of stock options, stock
appreciation rights, restricted stock, restricted stock units, unrestricted stock, other share-based awards and cash awards. Any
of these awards may, but need not, be made as performance incentives to reward attainment of performance goals in accordance with
the terms hereof. Stock options granted under the Plan may be non-qualified stock options or incentive stock options, as provided
herein.

General. The Board shall have such powers and authorities related to the administration of the Plan as are consistent
with the Company’s certificate of incorporation and bylaws and applicable law. The Board shall have the power and
authority to delegate its responsibilities hereunder to the Committee, which shall have full authority to act in accordance
with its charter (as in effect from time to time), and with respect to the power and authority of the Board to act hereunder,
all references to the Board shall be deemed to include a reference to the Committee, unless such power or authority

by applicable law, regulatory requirement or the certificate of incorporation or the bylaws of the Company, the Board shall
have full power and authority to take all actions and to make all determinations required or provided for under the Plan,
any Award or any Award Agreement, and shall have full power and authority to take all such other actions and make all such
other determinations not inconsistent with the specific terms and provisions of the Plan that the Board deems to be necessary

the extent consistent with applicable law and the applicable requirements of any securities exchange on which the Common
Stock may then be listed. All actions, determinations and decisions by the Board or the Committee under the Plan or any
Award Agreement, or with respect to any Award, shall be in the sole discretion of the Board and shall be final, binding and
conclusive on all persons. Without limitation, the Board shall have full and final power and authority, subject to the other

amend, modify or supplement the terms of any outstanding Award, including the authority, in order to effectuate the purposes of
the Plan, to modify Awards to foreign nationals or individuals who are employed outside the United States to recognize differences

    	 	5	 

     

    

 

3.2.
Award Agreements; Clawbacks.

 

The
grant of any Award may be contingent upon the Grantee executing the appropriate Award Agreement. The Company may retain the right
in an Award Agreement to cause a forfeiture of the gain realized by a Grantee on account of actions taken by the Grantee in violation
or breach of or in conflict with any employment agreement, non-competition agreement, any agreement prohibiting solicitation of
employees or clients of the Company or any Affiliate thereof or any confidentiality obligation with respect to the Company or
any Affiliate thereof, or otherwise in competition with the Company or any Affiliate thereof, to the extent specified in such
Award Agreement applicable to the Grantee. Furthermore, the Company may annul an Award if the Grantee is terminated for Cause.

 

All
awards, amounts or benefits received or outstanding under the Plan shall be subject to clawback, cancellation, recoupment, rescission,
payback, reduction or other similar action in accordance with the terms of any Company clawback or similar policy or any applicable
law related to such actions, as may be in effect from time to time. A Grantee’s acceptance of an Award shall be deemed to
constitute the Grantee’s acknowledgement of and consent to the Company’s application, implementation and enforcement
of any applicable Company clawback or similar policy that may apply to the Grantee, whether adopted prior to or following the
Effective Date, and any provision of applicable law relating to clawback, cancellation, recoupment, rescission, payback or reduction
of compensation, and the Grantee’s agreement that the Company may take such actions as may be necessary to effectuate any
such policy or applicable law, without further consideration or action.

 

3.3.
Deferral Arrangement.

 

The
Board may permit or require the deferral of any Award payment into a deferred compensation arrangement, subject to such rules
and procedures as it may establish and in accordance with Section 409A, which may include provisions for the payment or crediting
of interest or dividend equivalents, including converting such credits into deferred Share units.

 

3.4.
No Liability.

 

No
member of the Board or of the Committee shall be liable for any action or determination made in good faith with respect to the
Plan, any Award or Award Agreement.

any other provision of the Plan to the contrary, the Company may elect to satisfy any requirement under the Plan for the delivery
of stock certificates through the use of book entry.

Subject
to adjustment under Section 15, the total number of Shares authorized to be awarded under the Plan shall not exceed 4,500,000,
plus an annual increase on each anniversary of the Effective Date before the Termination Date equal to 3% of the total issued
and outstanding Shares as of such anniversary (or such lesser number of Shares as may be determined by the Board). Shares issued
under the Plan shall consist in whole or in part of authorized but unissued Shares, treasury Shares, or Shares purchased on the
open market or otherwise, all as determined by the Company from time to time.

 

    	 	6	 

     

    

 

4.2.
Share Counting.

 

Each
Share granted in connection with an Award shall be counted as one Share against the limit in Section 4.1, subject to this
Section 4.2. Share-based Performance Awards shall be counted assuming maximum performance results (if applicable) until
such time as actual performance results can be determined. Any Award settled in cash shall not be counted as issued Shares for
any purpose under the Plan. If any Award expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued
Shares covered by such Award shall again be available for the grant of Awards. If Shares issued pursuant to the Plan are repurchased
by, or are surrendered or forfeited to the Company at no more than cost, or are surrendered pursuant to an Option Exchange Program,
such Shares shall again be available for the grant of Awards. If Shares issuable upon exercise, vesting or settlement of an Award,
or Shares owned by a Grantee (which are not subject to any pledge or other security interest), are surrendered or tendered to
the Company in payment of the Option Price or Purchase Price of an Award or any taxes required to be withheld in respect of an
Award, in each case, in accordance with the terms and conditions of the Plan and any applicable Award Agreement, such surrendered
or tendered Shares shall again be available for the grant of Awards. Substitute Awards shall not be counted against the number
of Shares available for the grant of Awards.

    	 	7	 

     

    

 

6.2.
Successive Awards.

 

An
eligible person may receive more than one Award, subject to such restrictions as are provided herein.

 

6.3.
Stand-Alone, Additional, Tandem, and Substitute Awards.

 

Awards
may be granted either alone or in addition to, in tandem with, or in substitution or exchange for, any other Award or any award
granted under another plan of the Company, any Affiliate or any business entity to be acquired by the Company or an Affiliate,
or any other right of a Grantee to receive payment from the Company or any Affiliate. Such additional, tandem or substitute or
exchange Awards may be granted at any time. If an Award is granted in substitution or exchange for another award, the Board shall
have the right to require the surrender of such other award in consideration for the grant of the new Award. Subject to the requirements
of applicable law, the Board may make Awards in substitution or exchange for any other award under another plan of the Company,
any Affiliate or any business entity to be acquired by the Company or an Affiliate. In addition, Awards may be granted in lieu
of cash compensation, including in lieu of cash amounts payable under other plans of the Company or any Affiliate, in which the
value of Shares subject to the Award is equivalent in value to the cash compensation (for example, RSUs or Restricted Stock).

 

	7.	AWARD
                                         AGREEMENT

 

The
grant of any Award may be contingent upon the Grantee executing an appropriate Award Agreement, in such form or forms as the Board
shall from time to time determine. Without limiting the foregoing, an Award Agreement may be provided in the form of a notice
which provides that acceptance of the Award constitutes acceptance of all terms of the Plan and the notice. Award Agreements granted
from time to time or at the same time need not contain similar provisions but shall be consistent with the terms of the Plan.
Each Award Agreement evidencing an Award of Options shall specify whether such Options are intended to be Non-qualified Stock
Options or Incentive Stock Options, and in the absence of such specification such options shall be deemed Non-qualified Stock
Options.

 

	8.	TERMS
                                         AND CONDITIONS OF OPTIONS

 

8.1.
Option Price.

 

The
Option Price of each Option shall be fixed by the Board and stated in the related Award Agreement. The Option Price of each Option
intended to be an Incentive Stock Option (except those that constitute Substitute Awards) shall be at least the Fair Market Value
on the Grant Date; provided, however, that in the event that a Grantee is a Ten Percent Stockholder as of the Grant
Date, the Option Price of an Option granted to such Grantee that is intended to be an Incentive Stock Option shall be not less
than 110 percent of the Fair Market Value on the Grant Date. In no case shall the Option Price of any Option be less than the
par value of a Share.

 

8.2.
Vesting.

 

Subject
to Section 8.3, each Option shall become exercisable at such times and under such conditions (including performance requirements)
as stated in the Award Agreement.

 

8.3.
Term.

 

Each
Option shall terminate, and all rights to purchase Shares thereunder shall cease, upon the expiration of the Option term stated
in the Award Agreement not to exceed 10 years from the Grant Date, or under such circumstances and on such date prior thereto
as is set forth in the Plan or as may be fixed by the Board and stated in the related Award Agreement; provided, however,
that in the event that the Grantee is a Ten Percent Stockholder, an Option granted to such Grantee that is intended to be an Incentive
Stock Option at the Grant Date shall not be exercisable after the expiration of five years from its Grant Date.

 

    	 	8	 

     

    

 

8.4.
Limitations on Exercise of Option.

 

Notwithstanding
any other provision of the Plan, in no event may any Option be exercised, in whole or in part, (i) prior to the date the Plan
is approved by the Stockholders as provided herein or (ii) after the occurrence of an event which results in termination of the
Option.

 

8.5.
Method of Exercise.

 

An
Option that is exercisable may be exercised by the Grantee’s delivery of a notice of exercise to the Company, setting forth
the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares. To be effective,
notice of exercise must be made in accordance with procedures established by the Company from time to time.

 

8.6.
Rights of Holders of Options.

 

Unless
otherwise provided in the applicable Award Agreement, an individual holding or exercising an Option shall have none of the rights
of a Stockholder (for example, the right to receive cash or dividend payments or distributions attributable to the subject Shares
or to direct the voting of the subject Shares) until the Shares covered thereby are fully paid and issued to him. Except as provided
in Section 15 or the related Award Agreement, no adjustment shall be made for dividends, distributions or other rights
for which the record date is prior to the date of such issuance.

 

8.7.
Delivery of Stock Certificates.

 

Subject
to Section 3.5, promptly after the exercise of an Option by a Grantee and the payment in full of the Option Price, such
Grantee shall be entitled to the issuance of a stock certificate or certificates evidencing his or her ownership of the Shares
subject to the Option.

 

8.8.
Limitations on Incentive Stock Options.

 

An
Option shall constitute an Incentive Stock Option only (i) if the Grantee of such Option is an employee of the Company or any
Subsidiary of the Company; (ii) to the extent specifically provided in the related Award Agreement; and (iii) to the extent that
the aggregate Fair Market Value (determined at the time the Option is granted) of the Shares with respect to which all Incentive
Stock Options held by such Grantee become exercisable for the first time during any calendar year (under the Plan and all other
plans of the Grantee’s employer and its Affiliates) does not exceed $100,000. This limitation shall be applied by taking
Options into account in the order in which they were granted. No Option shall be treated as an Incentive Stock Option unless the
Plan has been approved by the Stockholders in a manner intended to comply with the stockholder approval requirements of Code Section
422, provided that any Option intended to be an Incentive Stock Option shall not fail to be effective solely on account
of a failure to obtain such approval, but rather such Option shall be treated as a Nonstatutory Stock Option unless and until
such approval is obtained.

 

8.9.
Early Exercise.

 

An
Option may, but need not, include a provision whereby the Grantee may elect at any time before the Grantee’s Separation
from Service to exercise the Option as to any part or all of the Shares subject to the Option prior to the full vesting of the
Option. Any unvested Shares so purchased may be subject to a repurchase option in favor of the Company or to any other restriction
the Board determines to be appropriate.

9.1.
Right to Payment.

 

A
SAR shall confer on the Grantee a right to receive, upon exercise thereof, the excess of (i) the Fair Market Value on the date
of exercise over (ii) the SAR Exercise Price. The Award Agreement for a SAR shall specify the SAR Exercise Price. SARs may be
granted alone or in conjunction with all or part of an Option or at any subsequent time during the term of such Option or in conjunction
with all or part of any other Award.

 

9.2.
Other Terms.

 

The
Board shall determine at the Grant Date or thereafter, the time or times at which and the circumstances under which a SAR may
be exercised in whole or in part (including based on achievement of performance goals and/or future service requirements), the
time or times at which SARs shall cease to be or become exercisable following Separation from Service or upon other conditions,
the method of exercise, whether or not a SAR shall be in tandem or in combination with any other Award and any other terms and
conditions of any SAR.

 

9.3.
Term of SARs.

 

The
term of a SAR granted under the Plan shall be determined by the Board; provided, however, that such term shall not
exceed 10 years.

 

9.4.
Payment of SAR Amount.

 

Upon
exercise of a SAR, a Grantee shall be entitled to receive payment from the Company (in cash or Shares, as set forth in the Award
Agreement) in an amount determined by multiplying:

 

(i)
the difference between the Fair Market Value on the date of exercise over the SAR Exercise Price; by

 

(ii)
the number of Shares with respect to which the SAR is exercised.

 

	10.	TERMS
                                         AND CONDITIONS OF RESTRICTED STOCK AND RESTRICTED STOCK UNITS

 

10.1.
Restrictions.

 

At
the time of grant, the Board may establish a period of time (a “Restricted Period”) and any additional restrictions
including the satisfaction of corporate or individual performance objectives applicable to an Award of Restricted Stock or RSUs.
Each Award of Restricted Stock or RSUs may be subject to a different Restricted Period and additional restrictions. Neither Restricted
Stock nor RSUs may be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the Restricted Period
or prior to the satisfaction of any other applicable restrictions.

 

10.2.
Restricted Stock Certificates.

 

Subject
to Section 3.5, the Company shall issue Shares, in the name of each Grantee to whom Restricted Stock has been granted,
stock certificates or other evidence of ownership representing the total number of Shares of Restricted Stock granted to the Grantee,
as soon as reasonably practicable after the Grant Date. The Board may provide in an Award Agreement that either (i) the Secretary
of the Company shall hold such certificates for the Grantee’s benefit until such time as the Restricted Stock is forfeited
to the Company or the restrictions lapse or (ii) such certificates shall be delivered to the Grantee; provided, however,
that such certificates shall bear a legend or legends that comply with the applicable securities laws and regulations and make
appropriate reference to the restrictions imposed under the Plan and the Award Agreement.

10.4.
Rights of Holders of RSUs.

 

10.4.1.
Settlement of RSUs.

 

RSUs
may be settled in cash or Shares, as set forth in the Award Agreement. The Award Agreement shall also set forth whether the RSUs
shall be settled (i) within the time period specified in Section 17.9 for short term deferrals or (ii) otherwise within
the requirements of Section 409A, in which case the Award Agreement shall specify upon which events such RSUs shall be settled.

 

10.4.2.
Voting and Dividend Rights.

 

Unless
otherwise provided in the applicable Award Agreement, holders of RSUs shall not have rights as Stockholders, including voting
or dividend or dividend equivalents rights.

 

10.4.3.
Creditor’s Rights.

 

A
holder of RSUs shall have no rights other than those of a general creditor of the Company. RSUs represent an unfunded and unsecured
obligation of the Company, subject to the terms and conditions of the applicable Award Agreement.

 

10.5.
Purchase of Restricted Stock.

 

The
Grantee shall be required, to the extent required by applicable law, to purchase the Restricted Stock from the Company at a Purchase
Price equal to the greater of (i) the aggregate par value of the Shares represented by such Restricted Stock or (ii) the Purchase
Price, if any, specified in the related Award Agreement. If specified in the Award Agreement, the Purchase Price may be deemed
paid by Services already rendered. The Purchase Price shall be payable in a form described in Section 11 or, if so determined
by the Board, in consideration for past Services rendered.

 

10.6.
Delivery of Shares.

 

Subject
to Section 3.5, upon the expiration or termination of any Restricted Period and the satisfaction of any other conditions
prescribed by the Board, the restrictions applicable to Shares of Restricted Stock or RSUs settled in Shares shall lapse, and,
unless otherwise provided in the applicable Award Agreement, a stock certificate for such Shares shall be delivered, free of all
such restrictions, to the Grantee or the Grantee’s beneficiary or estate, as the case may be.

 

	11.	FORM
                                         OF PAYMENT FOR OPTIONS AND RESTRICTED STOCK

 

11.1.

    	 	11	 

     

    

 

11.2.
Surrender of Shares.

 

To
the extent the Award Agreement so provides, payment of the Option Price for Shares purchased pursuant to the exercise of an Option
or the Purchase Price for Restricted Stock may be made all or in part through the tender to the Company of Shares, which Shares
shall be valued, for purposes of determining the extent to which the Option Price or Purchase Price for Restricted Stock has been
paid thereby, at their Fair Market Value on the date of exercise or surrender. Notwithstanding the foregoing, in the case of an
Incentive Stock Option, the right to make payment in the form of already-owned Shares may be authorized only at the time of grant.

 

11.3.
Cashless Exercise.

 

With
respect to an Option only (and not with respect to Restricted Stock) following the Initial Public Offering, to the extent permitted
by law and to the extent the Award Agreement so provides, payment of the Option Price may be made all or in part by delivery (on
a form acceptable to the Company) of an irrevocable direction to a licensed securities broker acceptable to the Company to sell
Shares and to deliver all or part of the sales proceeds to the Company in payment of the Option Price and any withholding taxes
described in Section 17.3.

 

11.4.
Other Forms of Payment.

 

To
the extent the Award Agreement so provides, payment of the Option Price or the Purchase Price for Restricted Stock may be made
in any other form that is consistent with applicable laws, regulations and rules, including the Company’s withholding of

	12.	TERMS
                                         AND CONDITIONS OF PERFORMANCE AWARDS

 

The
right of a Grantee to exercise or receive a grant or settlement of any Award, and the timing thereof, may be subject to such performance
conditions as may be specified by the Board. The Board may use such business criteria and other measures of performance as it
may deem appropriate in establishing any performance conditions, and may reduce the amounts payable under any Award subject to
performance conditions.

 

	13.	other
                                         SHARE-based awards

 

13.1.
Grant of Other Share-based Awards.

 

Other
Share-based Awards may be granted either alone or in addition to or in conjunction with other Awards. Other Share-based Awards
may be granted in lieu of other cash or other compensation to which a Service Provider is entitled from the Company or may be
used in the settlement of amounts payable in Shares under any other compensation plan or arrangement of the Company, including
any other Company incentive compensation plan. The Board shall determine the persons to whom and the time or times at which such
Awards will be made, the number of Shares to be granted pursuant to such Awards, and all other terms and conditions of such Awards.
Unless the Board determines otherwise, any such Award shall be confirmed by an Award Agreement, which shall contain such provisions
as the Board determines to be necessary or appropriate to carry out the intent of the Plan with respect to such Award.

 

13.2.
Terms of Other Share-based Awards.

 

Any
Common Stock subject to Awards made under this Section 13 may not be sold, assigned, transferred, pledged or otherwise

	14.	REQUIREMENTS
                                         OF LAW

 

14.1.
General.

 

The
Company shall not be required to sell or issue any Shares under any Award if the sale or issuance of such Shares would constitute
a violation by the Grantee, any other individual exercising an Option or the Company of any provision of any law or regulation
of any governmental authority, including any federal or state securities laws or regulations. If at any time the Board determines
that the listing, registration or qualification of any Shares subject to an Award upon any securities exchange or under any governmental
regulatory body is necessary or desirable as a condition of, or in connection with, the issuance or purchase of Shares hereunder,
no Shares may be issued or sold to the Grantee or any other individual exercising an Option pursuant to such Award unless such
listing, registration, qualification, consent or approval shall have been effected or obtained free of any conditions not acceptable
to the Company, and any delay caused thereby shall in no way affect the date of termination of the Award. Specifically, in connection
with the Securities Act, upon the exercise of any Option or the delivery of any Shares underlying an Award, unless a registration
statement under such Act is in effect with respect to the Shares covered by such Award, the Company shall not be required to sell
or issue such Shares unless the Board has received evidence satisfactory to it that the Grantee or any other individual exercising
an Option may acquire such Shares pursuant to an exemption from registration under the Securities Act. The Company may, but shall
in no event be obligated to, register any securities covered hereby pursuant to the Securities Act. The Company shall not be obligated
to take any affirmative action in order to cause the exercise of an Option or the issuance of Shares pursuant to the Plan to comply
with any law or regulation of any governmental authority. As to any jurisdiction that expressly imposes the requirement that an
Option shall not be exercisable until the Shares covered by such Option are registered or are exempt from registration, the exercise
of such Option (under circumstances in which the laws of such jurisdiction apply) shall be deemed conditioned upon the effectiveness
of such registration or the availability of such an exemption. The Board may require the Grantee to sign such additional documentation,
make such representations, and furnish such information as the Board may consider appropriate in connection with the grant of
Awards or issuance or delivery of Shares in compliance with applicable laws.

 

14.2.
Section 25102(o) of the California Corporations Code.

 

The
Plan is intended to comply with Section 25102(o) of the California Corporations Code. In that regard, to the extent required by
Section 25102(o), (i) the terms of any Options or SARs, to the extent vested and exercisable upon a Grantee’s Separation
from Service, shall include any minimum exercise periods following Separation from Service specified by Section 25102(o), and
(ii) any repurchase right of the Company with respect to Shares issued under the Plan shall include a minimum 90-day notice requirement.
Any provision of the Plan which is inconsistent with Section 25102(o) shall, without further act or amendment by the Company or
the Board, be reformed to comply with the requirements of Section 25102(o).

 

14.3.
Rule 16b-3.

 

During
any time when the Company has a class of equity security registered under Section 12 of the Exchange Act, it is the intent of
the Company that Awards and the exercise of Options will qualify for the exemption provided by Rule 16b-3 under the Exchange Act.
To the extent that any provision of the Plan or action by the Board or Committee does not comply with the requirements of Rule
16b-3, it shall be deemed inoperative to the extent permitted by law and deemed advisable by the Board, and shall not affect the
validity of the Plan. In the event that Rule 16b-3 is revised or replaced, the Board may modify the Plan in any respect necessary
to satisfy the requirements of, or to take advantage of any features of, the revised exemption or its replacement.

	15.	EFFECT
                                         OF CHANGES IN CAPITALIZATION

 

15.1.
Adjustments for Changes in Capital Structure.

 

Subject
to any required action by the Stockholders, in the event of any change in the Common 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 Stockholders in
a form other than Shares (excepting normal cash dividends) that has a material effect on the Fair Market Value, appropriate and
proportionate adjustments shall be made in the number and class of shares subject to the Plan and to any outstanding Awards, and
in the Option Price, SAR Exercise Price or Purchase Price per Share of any outstanding Awards in order to prevent dilution or
enlargement of Grantees’ 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 a Change in Control) shares of another corporation (the “New Shares”),
the Board 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 Option Price, SAR Exercise Price or Purchase Price per Share of, the outstanding
Awards shall be adjusted in a fair and equitable manner. Any fractional share resulting from an adjustment pursuant to this Section
15.1 shall be rounded down to the nearest whole number and the Option Price, SAR Exercise Price or Purchase 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. The Board may also make such adjustments in the terms of any Award
to reflect, or related to, such changes in the capital structure of the Company or distributions as it deems appropriate. Adjustments
determined by the Board pursuant to this Section 15.1 shall be made in accordance with Section 409A to the extent applicable.

 

15.2.
Change in Control.

 

15.2.1.
Consequences of a Change in Control.

 

Subject
to the requirements and limitations of Section 409A if applicable, the Board may provide for any one or more of the following
in connection with a Change in Control, which such actions need not be the same for all Grantees:

 

(a)
Accelerated Vesting. The Board may 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, vesting and/or settlement in connection
with such Change in Control of each or any outstanding Award or portion thereof and Shares acquired pursuant thereto upon such
terms and conditions, including termination of the Grantee’s Service prior to, upon, or following such Change in Control,
to such extent as determined by the Board.

 

(b)
Assumption, Continuation or Substitution. 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 Grantee, 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 with respect to the Acquiror’s stock, as applicable. For purposes
of this Section 15.2.1, an Award denominated in Shares 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 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 Stockholder on the effective date of the Change in Control was entitled; provided,
however, that if such consideration is not solely common stock of the Acquiror, the Board may, with the consent of the
Acquiror, provide for the consideration to be received upon the exercise or settlement of the Award, for each Share subject to
the Award, to consist solely of common stock of the Acquiror equal in Fair Market Value to the per Share consideration received
by Stockholders pursuant to the Change in Control. If any portion of such consideration may be received by Stockholders pursuant
to the Change in Control on a contingent or delayed basis, the Board may determine such Fair Market Value as of the time of the
Change in Control on the basis of the Board’s estimate of the present value of the probable future payment of such consideration.
Any Award or portion thereof which is neither assumed or continued by the Acquiror in connection with the Change in Control nor
exercised or settled 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.

 

    	 	14	 

     

    

 

(c)
Cash-Out of Awards. The Board may, without the consent of any Grantee, determine that, upon the occurrence of a Change
in Control, each or any Award or a portion thereof outstanding immediately prior to the Change in Control and not previously exercised
or settled shall be canceled in exchange for a payment with respect to each vested Share (and each unvested Share, if so determined
by the Board) subject to such canceled Award in (i) cash, (ii) stock of the Company or of a corporation or other business entity
a party to the Change in Control or (iii) other property which, in any such case, shall be in an amount having a Fair Market Value
equal to the Fair Market Value of the consideration to be paid per Share in the Change in Control, reduced by the exercise or
purchase price per Share, if any, under such Award. If any portion of such consideration may be received by Stockholders pursuant
to the Change in Control on a contingent or delayed basis, the Board may determine such Fair Market Value as of the time of the
Change in Control on the basis of the Board’s estimate of the present value of the probable future payment of such consideration.
In the event such determination is made by the Board, the amount of such payment (reduced by applicable withholding taxes, if
any) shall be paid to Grantees in respect of the vested portions of their canceled Awards as soon as practicable following the
date of the Change in Control and in respect of the unvested portions of their canceled Awards in accordance with the vesting
schedules applicable to such Awards. For avoidance of doubt, if the amount determined pursuant to this Section 15.2.1(c)
for an Option or SAR is zero or less, the affected Option or SAR may be cancelled without any payment therefore.

 

15.2.2.
Change in Control Defined.

 

Unless
other provided in the applicable Award Agreement, a “Change in Control” means the consummation of any of the
following events:

 

(a)
the acquisition, other than from the Company, by any individual, entity or group (within the meaning of Section 13(d)(3) or Section
14(d)(2) of the Exchange Act), other than the Company or any subsidiary, affiliate (within the meaning of Rule 144 promulgated
under the Securities Act) or employee benefit plan of the Company, of beneficial ownership (within the meaning of Rule 13d-3 promulgated
under the Exchange Act) of more than 50% of the combined voting power of the then outstanding voting securities of the Company
entitled to vote generally in the election of directors (the “Voting Securities”); or

 

(b)
a reorganization, merger, consolidation or recapitalization of the Company (a “Business Combination”), other
than a Business Combination in which more than 50% of the combined voting power of the outstanding voting securities of the surviving
or resulting entity immediately following the Business Combination is held by the persons who, immediately prior to the Business
Combination, were the holders of the Voting Securities; or

 

(c)
a complete liquidation or dissolution of the Company, or a sale of all or substantially all of the assets of the Company; or

 

    	 	15	 

     

    

 

(d)
during any period of 24 consecutive months, the Incumbent Directors cease to constitute a majority of the Board ; “Incumbent
Directors” means individuals who were members of the Board at the beginning of such period or individuals whose election
or nomination for election to the Board by the Stockholders was approved by a vote of at least a majority of the then Incumbent
Directors (but excluding any individual whose initial election or nomination is in connection with an actual or threatened proxy
contest relating to the election of directors).

 

Notwithstanding
the foregoing, if it is determined that an Award is subject to the requirements of Section 409A and payable upon a Change in Control,
the Company will not be deemed to have undergone a Change in Control for purposes of the Plan unless the Company is deemed to
have undergone a “change in control event” pursuant to the definition of such term in Section 409A.

 

15.3.
Adjustments.

 

Adjustments
under this Section 15 related to Shares or other securities of the Company shall be made by the Board. No fractional Shares
or other securities shall be issued pursuant to any such adjustment, and any fractions resulting from any such adjustment shall
be eliminated in each case by rounding downward to the nearest whole Share.

 

16.
No Limitations on Company

 

The
making of Awards shall not affect or limit in any way the right or power of the Company to make adjustments, reclassifications,
reorganizations or changes of its capital or business structure or to merge, consolidate, dissolve or liquidate, or to sell or
transfer all or any part of its business or assets.

 

17.
TERMS APPLICABLE GENERALLY TO AWARDS GRANTED UNDER THE PLAN

 

17.1.
Disclaimer of Rights.

 

No
provision in the Plan or in any Award Agreement shall be construed to confer upon any individual the right to remain in the employ
or service of the Company or any Affiliate, or to interfere in any way with any contractual or other right or authority of the
Company or any Affiliate either to increase or decrease the compensation or other payments to any individual at any time, or to
terminate any employment or other relationship between any individual and the Company or any Affiliate. In addition, notwithstanding
anything contained in the Plan to the contrary, unless otherwise provided in the applicable Award Agreement, no Award granted
under the Plan shall be affected by any change of duties or position of the Grantee, so long as such Grantee continues to be a
Service Provider. The obligation of the Company to pay any benefits pursuant to the Plan shall be interpreted as a contractual
obligation to pay only those amounts described herein, in the manner and under the conditions prescribed herein. The Plan shall
in no way be interpreted to require the Company to transfer any amounts to a third party trustee or otherwise hold any amounts
in trust or escrow for payment to any Grantee or beneficiary under the terms of the Plan.

 

17.2.
Nonexclusivity of the Plan.

 

Neither
the adoption of the Plan nor the submission of the Plan to the Stockholders for approval shall be construed as creating any limitations
upon the right or authority of the Board or its delegate to adopt such other compensation arrangements as the Board or its delegate
determines desirable.

 

    	 	16	 

     

    

 

17.3.
Withholding Taxes.

 

The
Company or an Affiliate, as the case may be, shall have the right to deduct from payments of any kind otherwise due to a Grantee
any federal, state or local taxes of any kind required by law to be withheld (i) with respect to the vesting of or other lapse
of restrictions applicable to an Award, (ii) upon the issuance of any Shares upon the exercise of an Option or SAR or (iii) otherwise
due in connection with an Award. At the time of such vesting, lapse or exercise, the Grantee shall pay to the Company or the Affiliate,
as the case may be, any amount that the Company or the Affiliate may reasonably determine to be necessary to satisfy such withholding
obligation. Subject to the prior approval of the Board, the Grantee may elect to satisfy such obligations, in whole or in part,
(i) by causing the Company or the Affiliate to withhold the minimum required number of Shares otherwise issuable to the Grantee
as may be necessary to satisfy such withholding obligation or (ii) by delivering to the Company or the Affiliate Shares already
owned by the Grantee. The Shares so delivered or withheld shall have an aggregate Fair Market Value equal to such withholding
obligations. The Fair Market Value of the Shares used to satisfy such withholding obligation shall be determined by the Company
or the Affiliate as of the date that the amount of tax to be withheld is to be determined. A Grantee who has made an election
pursuant to this Section 17.3 may satisfy his or her withholding obligation only with Shares that are not subject to any
repurchase, forfeiture, unfulfilled vesting or other similar requirements.

 

17.4.
Right of First Refusal; Right to Repurchase.

 

17.4.1.
Right of First Refusal.

 

Unless
otherwise provided in the applicable Award Agreement, stockholders’ agreement or other agreement to which a Holder is a
party, at any time prior to registration by the Company of its Common Stock under Section 12 of the Exchange Act, in the event
that the Holder desires at any time to sell or otherwise transfer all or any part of such Holder’s Issued Shares (to the
extent vested), the Holder first shall give written notice to the Company of the Holder’s intention to make such transfer.
Such notice shall state the number of Issued Shares which the Holder proposes to sell (the “Offered Shares”),
the price and the terms at which the proposed sale is to be made and the name and address of the proposed transferee. At any time
within 30 days after the receipt of such notice by the Company, the Company or its assigns may elect to purchase all or any portion
of the Offered Shares at the price and on the terms offered by the proposed transferee and specified in the notice. The Company
or its assigns shall exercise this right by mailing or delivering written notice to the Holder within the foregoing 30-day period.
If the Company or its assigns elect to exercise its purchase rights under this Section 17.4.1, the closing for such purchase
shall, in any event, take place within 45 days after the receipt by the Company of the initial notice from the Holder. In the
event that the Company or its assigns do not elect to exercise such purchase right, or in the event that the Company or its assigns
do not pay the full purchase price within such 45-day period, the Holder may, within 60 days thereafter, sell the Offered Shares
to the proposed transferee at the same price and on the same terms as specified in the Holder’s notice. Any Issued Shares
purchased by such proposed transferee shall continue to be subject to the terms of the Plan. Any Issued Shares not sold to the
proposed transferee shall remain subject to the Plan.

 

17.4.2.
Right of Repurchase.

 

Unless
otherwise provided in the applicable Award Agreement, stockholders’ agreement or other agreement to which a Grantee is a
party, at any time prior to registration by the Company of its Common Stock under Section 12 of the Exchange Act, in the case
of any Grantee whose Separation from Service is for Cause, or where the Grantee has, in the Board’s reasonable determination,
taken any action prior to or following his Separation of Service which would have constituted grounds for Cause, the Company shall
have the right, exercisable at any time and from time to time thereafter, to repurchase from the Grantee (or any successor in
interest by purchase, gift or other mode of transfer) any Shares issued to such Grantee under the Plan for the purchase price
paid by the Grantee for such Shares (or the Fair Market Value of such Common Stock at the time of repurchase, if lower).

 

    	 	17	 

     

    

 

17.5.
Market Standoff Requirement.

 

Unless
otherwise provided in the applicable Award Agreement, stockholders’ agreement or other agreement to which a Grantee is a
party, in connection with any underwritten public offering of its Common Stock (“Offering”) and upon request
of the Company or the underwriters managing the Offering, Grantees shall not be permitted to sell, make any short sale of, loan,
grant any option for the purchase of, or otherwise directly or indirectly dispose of any Shares delivered under the Plan (other
than those Shares included in the Offering) without the prior written consent of the Company or such underwriters, as the case
may be, for such period of time (not to exceed 180 days) from the effective date of the registration statement with respect to
such Offering as may be requested by the Company or such managing underwriters and to execute an agreement reflecting the foregoing
as may be requested by the underwriters in connection with such Offering.

 

17.6.
Other Provisions.

 

Each
Award Agreement may contain such other terms and conditions not inconsistent with the Plan as may be determined by the Board.
In the event of any conflict between the terms of an employment agreement and the Plan, the terms of the employment agreement
shall govern.

 

17.7.
Severability.

 

If
any provision of the Plan or any Award Agreement shall be determined to be illegal or unenforceable by any court of law in any
jurisdiction, the remaining provisions hereof and thereof shall be severable and enforceable in accordance with their terms, and
all provisions shall remain enforceable in any other jurisdiction.

 

17.8.
Governing Law.

 

The
Plan and all Award Agreements shall be construed in accordance with and governed by the laws of the State of California without
regard to the principles of conflicts of law that could cause the application of the laws of any jurisdiction other than the State
of California. For purposes of resolving any dispute that arises under the Plan, each Grantee, by virtue of receiving an Award,
shall be deemed to have submitted to and consented to the exclusive jurisdiction of the State of California and to have agreed
that any related litigation shall be conducted solely in the courts of Orange County, California or the federal courts for the
U.S. for the Central District of California, where the Plan is made and to be performed, and no other courts. The Plan is not
intended to be subject to the Employee Retirement Income Security Act of 1974.

 

17.9.
Section 409A.

 

The
Plan is intended to comply with Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted,
the Plan shall be interpreted and administered to be in compliance therewith. Any payments described in the Plan that are due
within the “short-term deferral period” as defined in Section 409A shall not be treated as deferred compensation unless
applicable laws require otherwise. For purposes of Section 409A, each installment payment under the Plan shall be treated as a
separate payment. Notwithstanding anything to the contrary in the Plan, to the extent required to avoid accelerated taxation and
tax penalties under Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided pursuant
to the Plan during the six-month period immediately following the Grantee’s Separation from Service shall instead be paid
on the first payroll date after the six-month anniversary of the Grantee’s Separation from Service (or the Grantee’s
death, if earlier). Notwithstanding the foregoing, neither the Company nor the Committee shall have any obligation to take any
action to prevent the assessment of any excise tax or penalty on any Grantee under Section 409A and neither the Company nor the
Board shall have any liability to any Grantee for such tax or penalty.

 

    	 	18	 

     

    

 

17.10.
Separation from Service.

 

The
Board shall determine the effect of a Separation from Service upon Awards, and such effect shall be set forth in the applicable
Award Agreement. Without limiting the foregoing, the Board may provide in the Award Agreements at the time of grant, or any time
thereafter with the consent of the Grantee, the actions that will be taken upon the occurrence of a Separation from Service, including
accelerated vesting or termination, depending upon the circumstances surrounding the Separation from Service.

 

17.11.
Transferability of Awards and Issued Shares.

 

17.11.1.
Transfers in General.

 

Except
as provided in Section 17.11.2, no Award shall be assignable or transferable by the Grantee to whom it is granted, other
than by will or the laws of descent and distribution, and, during the lifetime of the Grantee, only the Grantee personally (or
the Grantee’s personal representative) may exercise rights under the Plan.

 

17.11.2.
Family Transfers.

 

If
authorized in the applicable Award Agreement, a Grantee may transfer, not for value, all or part of an Award (other than Incentive
Stock Options) to any Family Member. For the purpose of this Section 17.11.2, a “not for value” transfer is
a transfer which is (i) a gift, (ii) a transfer under a domestic relations order in settlement of marital property rights or (iii)
a transfer to an entity in which more than 50% of the voting interests are owned by Family Members (or the Grantee) in exchange
for an interest in that entity. Following a transfer under this Section 17.11.2, any such Award shall continue to be subject
to the same terms and conditions as were applicable immediately prior to transfer. Subsequent transfers of transferred Awards
are prohibited except to Family Members of the original Grantee in accordance with this Section 17.11.2 or by will or the
laws of descent and distribution.

 

17.11.3.
Issued Shares.

 

No
Issued Shares shall be sold, assigned, transferred, pledged, hypothecated, given away or in any other manner disposed of or encumbered,
whether voluntarily or by operation of law, unless (i) such transfer is in compliance with the terms of the applicable Award,
all applicable securities laws, and with the terms and conditions of the Plan (including Sections 17.4 and 17.5
and this Section 17.11.3), (ii) such transfer does not cause the Company to become subject to the reporting requirements
of the Exchange Act, and (iii) the transferee consents in writing to be bound by the terms and conditions of the Plan (including
Sections 17.4 and 17.5 and this Section 17.11.3). In connection with any proposed transfer, the Board may
require the transferor to provide at the transferor’s own expense an opinion of counsel to the transferor, satisfactory
to the Board, that such transfer is in compliance with all foreign, federal and state securities laws. Any attempted disposition
of Issued Shares not in accordance with the terms and conditions of this Section 17.11.3 shall be null and void, and the
Company shall not reflect on its records any change in record ownership of any Issued Shares as a result of any such disposition,
shall otherwise refuse to recognize any such disposition and shall not in any way give effect to any such disposition of Issued
Shares. Subject to the foregoing general provisions, and unless otherwise provided in the applicable Award Agreement, Issued Shares
may be transferred pursuant to the following specific terms and conditions:

 

    	 	19	 

     

    

 

(a)
Transfers to Permitted Transferees. The Holder may sell, assign, transfer or give away any or all of the Issued Shares
to Permitted Transferees; provided, however, that following such sale, assignment or other transfer, such Issued Shares
shall continue to be subject to the terms of the Plan (including Sections 17.4 and 17.5 and this Section 17.11.3)
and such Permitted Transferee(s) shall, as a condition to any such transfer, deliver a written acknowledgment to that effect to
the Company.

 

(b)
Transfers upon Death. Upon the death of the Holder, any Issued Shares then held by the Holder at the time of such death
and any Issued Shares acquired thereafter by the Holder’s legal representative shall be subject to the terms and conditions
of the Plan, and the Holder’s estate, executors, administrators, personal representatives, heirs, legatees and distributees
shall be obligated to convey such Issued Shares to the Company or its assigns under the terms contemplated hereby.

 

17.12.
Dividends and Dividend Equivalent Rights.

 

If
specified in the Award Agreement, the recipient of an Award may be entitled to receive, currently or on a deferred basis, dividends
or dividend equivalents with respect to the Common Stock or other securities covered by an Award. The terms and conditions of
a dividend equivalent right may be set forth in the Award Agreement. Dividend equivalents credited to a Grantee may be paid currently
or may be deemed to be reinvested in additional Shares or other securities of the Company at a price per unit equal to the Fair
Market Value on the date that such dividend was paid to Stockholders. Notwithstanding the foregoing, dividends or dividend equivalents
shall not be paid on any Award or portion thereof that is unvested or on any Award that is subject to the achievement of performance
criteria before the Award has become earned and payable.

 

17.13.
Plan Construction.

 

In
the Plan, unless otherwise stated, the following uses apply: (i) references to a statute or law refer to the statute or law and
any amendments and any successor statutes or laws, and to all valid and binding governmental regulations, court decisions and
other regulatory and judicial authority issued or rendered thereunder, as amended, or their successors, as in effect at the relevant
time; (ii) in computing periods from a specified date to a later specified date, the words “from” and “commencing
on” (and the like) mean “from and including,” and the words “to,” “until” and “ending
on” (and the like) mean “to and including”; (iii) indications of time of day shall be based upon the time applicable
to the location of the principal headquarters of the Company; (iv) the words “include,” “includes” and
“including” (and the like) mean “include, without limitation,” “includes, without limitation”
and “including, without limitation” (and the like), respectively; (v) all references to articles and sections are
to articles and sections in the Plan; (vi) all words used shall be construed to be of such gender or number as the circumstances
and context require; (vii) the captions and headings of articles and sections have been inserted solely for convenience of reference
and shall not be considered a part of the Plan, nor shall any of them affect the meaning or interpretation of the Plan or any
of its provisions; (viii) any reference to an agreement, plan, policy, form, document or set of documents, and the rights and
obligations of the parties under any such agreement, plan, policy, form, document or set of documents, shall mean such agreement,
plan, policy, form, document or set of documents as amended from time to time, and any and all modifications, extensions, renewals,
substitutions or replacements thereof; and (ix) all accounting terms not specifically defined shall be construed in accordance
with GAAP.

 

17.14.
Data Protection

 

A
Grantee’s acceptance of an Award shall be deemed to constitute the Grantee’s acknowledgement of and consent to the
collection and processing of personal data relating to the Grantee so that the Company can meet its obligations and exercise its
rights under the Plan and generally administer and manage the Plan. This data shall include data about participation in the Plan
and Shares offered or received, purchased, or sold under the Plan and other appropriate financial and other data (such as the
date on which the Awards were granted) about the Grantee and the Grantee’s participation in the Plan.

 

17.15.
Company Cancellation Right.

 

Subject
to applicable laws (including U.S. federal state, and local laws, rules and regulations, and those of any other country or jurisdiction
where Options are granted, and the rules and requirements of any stock exchange on which the Common Stock is traded at that time),
if the Fair Market Value for Shares subject to any Option is more than 50% below their exercise price for more than 90 consecutive
business days, the Board unilaterally may declare the Option terminated, effective on the date the Board provides written notice
to the Grantee. The Board may take such action with respect to any or all Options and with respect to any individual Option holder
or class(es) of Option holders.
