in this Plan to the “Committee” shall mean the Board if no Committee has been appointed.

 

4.2.           
Duties of Administrator. Subject to ratification of the grant or authorization of each Award by the Committee (if
so required by applicable state law), and subject to the terms of the Plan, the Committee shall have the authority to (i) determine
to whom (from among the class of persons eligible under Section 5 to receive Awards) Awards shall be granted; (ii) determine the
time or times at which Awards shall be granted; (iii) determine the purchase price of Shares subject to each Award, (iv) determine
whether each Option granted shall be an ISO or a NQO; (v) determine the time or times when each Award shall become exercisable
and the duration of the exercise period; (vi) determine any other provisions applicable to the Award and the shares of Common Stock
issuable upon exercise thereof; (vii) interpret the Plan and prescribe and rescind rules and regulations relating to it; and (viii)
make all other determinations necessary or advisable for administration of the Plan. The interpretation and construction by the

Section

Eligibility

 

The Committee may grant Awards to those
employees, officers, directors, consultants and advisors whom the Committee, in its sole discretion, identifies as being in a position
which enables such individuals to contribute to the continued growth, development and future financial success of the Company.
A director, officer or other person who is not also an employee of the Company shall not be eligible to receive an ISO. The granting
of any Award to any individual shall neither entitle that individual to, nor disqualify him or her from, participation in any other
grant of Awards.

 

Section

Stock Reserved For Awards

Aggregate Number of Shares Available for Awards. Subject to adjustment as provided in Section 10, the maximum number
of Shares to be reserved for issuance under the Plan as Awards, including Incentive Stock Options, shall be 1,350,000 Shares. Any
or all of the Shares subject to Awards under the Plan may be authorized but unissued Shares, or issued Shares that have been or
shall have been reacquired by the Company, as the Board may from time to time determine.

6.2.

without having been exercised in full or shall cease for any reason to be exercisable in whole or in part, the unpurchased shares
subject to such Award shall again be available for grants of Awards under the Plan unless the Plan shall have been terminated.

 

Section
7

Stock Options

 

7.1.           
Grant of Options. Subject to the limitations of the Plan, the Committee may, after consultation with and consideration
of the recommendations of management and the Board as the Committee deems desirable, select those individuals to be granted Options
and determine the time when each such Option shall be granted and such other terms of each Option. The Committee shall clearly
designate and identify each Option at the time it is granted as either an ISO or a Non-Qualified Option, as the case may be. The
Grant Date of an Option under the Plan will be the date specified by the Committee at the time it grants the Option; provided,
however, that such date shall not be prior to the date on which the Committee acts to approve the grant. ISOs may be granted only
to persons who are employees of the Company on the Grant Date. The Company shall have no liability to a Participant or to any other
party if an Option (or any portion thereof) that is intended to be an ISO is determined not to be an ISO (including, without limitation,
due to the determination that the exercise price per share of the Option was less than the fair market value per share as of the
Grant Date). The Committee may grant both ISOs and NQOs to the same employee, and the exercise of one such Option does not in any
way affect the employee’s right to exercise the other.

 

7.2.           
Exercise Price. Unless the Committee determines otherwise, the exercise price specified in the Option Agreement relating
to each Option granted under the Plan shall be not less than one hundred percent (100%) of the Fair Market Value on the Grant Date.
In the case of an ISO, the exercise price of an ISO shall be not less than 100% of the Fair Market Value on the Grant Date; provided
however that if on the Grant Date, the Participant owns or is deemed to own (by reason of the attribution rules of Section 424(d)
of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company
or any parent or subsidiary, the exercise price per share specified in the agreement relating to such ISO shall not be less than
one hundred ten percent (110%) of the Fair Market Value per share of Common Stock on the Grant Date.

 

7.3.           
Exercise of Options. Options shall become exercisable at such time or times as shall be determined by the Committee
at or after the Grant Date. The Committee may at any time accelerate the exercisability of all or any portion of any Option.

 

    -4-

     

    

 

7.4.           
Method of Exercise. An Option (or any part or installment thereof) shall be exercised by giving written notice to
the Company at its principal office address, or to such transfer agent as the Company shall designate. Such notice shall identify
the Option being exercised and specify the number of shares as to which such Option is being exercised, accompanied by full payment
of the purchase price therefore either (a) in United States dollars in cash or by check, (b) subject to the Committee’s discretion
at the time of exercise, by the Optionee’s full recourse promissory note in a form approved by the Committee, (c) subject
to the Committee’s discretion, delivery of a properly executed exercise notice together with irrevocable instructions to
a broker to deliver to the Company promptly the amount of the proceeds of the sale of all or a portion of the Option Shares or
of a loan from the broker to the Optionee required to pay the exercise price, (d) subject to the Committee’s discretion at
the time of exercise, by tender to the Company of Common Stock owned by the Optionee, having a Fair Market Value on the date of
tender not less than the exercise price, or (e) at the discretion of the Committee, by any combination of (a), (b), (c) and (d).

 

7.5.           
Option Term. The term of each Option shall be fixed by the Committee; provided however that unless otherwise provided
on the Option Agreement, no Option shall be exercisable more than ten (10) years after the date the Option is granted provided,
further that if an ISO is granted to an Participant who, together with persons whose stock ownership is attributed to the Participant
pursuant to Section 424(d) of the Code, owns stock possessing more than ten percent (10%) of the total combined voting power of
all classes of stock of the Company, the ISO may not be exercised after the expiration of five (5) years from the Grant Date. The
only exception to the Option Term is for the Scientific Founder, Daniel Kalman, PhD, who will be permitted to exercise his Option
up to twenty (20) years after the date the Option is granted.

 

7.6.           
Annual Limit on Incentive Stock Options. Each eligible employee may be granted Options treated as ISOs only to the
extent that, in the aggregate under this Plan and all incentive stock option plans of the Company, ISOs do not become exercisable
for the first time by such employee during any calendar year with respect to stock having a fair market value (determined at the
time the ISOs were granted) in excess of $100,000. The Company intends to designate any Options granted in excess of such limitation
as NQOs.

 

7.7.           
Termination of Employment, Death and Disability

 

7.7.1.     
ISO. Unless otherwise specified in the agreement relating to such ISO, if a Participant ceases to be employed by
the Company (including retirement) other than by reason of death or Disability, no further installments of his or her ISOs shall
become exercisable, and his or her ISOs shall terminate on the earlier of (a) ninety (90) days after the date of termination of
his or her employment provided, however, if such termination occurs by reason of death or Disability, such period
shall be extended to one (1) year following the date of such event, or (b) their specified expiration dates, except to the extent
that such ISOs (or unexercised installments thereof) have been converted into Non-Qualified Options pursuant to Section 7.8 hereof.

 

7.7.2.     
Non-Qualified Option. The Committee, in its discretion, shall determine the extent, if any, to which the grantee
of a Non-Qualified Option may exercise said Option upon his or her termination of employment with the Company. If not otherwise
specified in the Award Agreement, a Non-Qualified Option must be exercised no later than the thirtieth (30th) day after
the Participant’s cessation of service with the Company.

 

    -5-

     

    

 

7.7.3.     
Leave of Absence. For purposes of this Section, employment shall be considered as continuing uninterrupted during
any bona fide leave of absence (such as those attributable to illness, military obligations or governmental service) provided that
the period of such leave does not exceed ninety (90) days or, if longer, any period during which such Participant’s right
to reemployment is guaranteed by statute. A bona fide leave of absence with the written approval of the Committee shall not be
considered an interruption of employment, provided that such written approval contractually obligates the Company to continue the
employment of the Participant after the approved period of absence.

 

7.8.           
Transferability of Options. Except as otherwise provided in an Award Agreement pertaining to NQOs, (i) no Option
shall be assignable or transferable by the grantee except by will or by the laws of descent and distribution nor shall an Option
be subject to attachment, execution or similar process. Except as set forth in the previous sentence and except as otherwise provided
in an Award Agreement pertaining to NQOs, during the lifetime of a grantee, each Option shall be exercisable only by such grantee.
In the event of (a) any attempt by the Participant to alienate, assign, pledge, hypothecate or otherwise dispose of the Option,
except as provided in this Plan, or (b) the levy of any attachment, execution or similar process upon the rights or interest hereby
conferred, the Company may terminate the Option by notice to the Participant and it shall thereupon become null and void.

 

7.9.           
Conversion of ISOs to Non-Qualified Options. The Committee, at the written request or with the written consent of
any Participant, may in its discretion take such actions as may be necessary to convert such Participant’s ISOs (or any installments
or portions of installments thereof) that have not been exercised on the date of conversion into Non-Qualified Options at any time
prior to the expiration of such ISOs, regardless of whether the Participant is an employee of the Company at the time of such conversion.
Such actions may include, but shall not be limited to, extending the exercise period or reducing the exercise price of the appropriate
installments of such ISOs. At the time of such conversion, the Committee (with the consent of the Participant) may impose such
conditions on the exercise of the resulting Non-Qualified Options as the Committee in its discretion may determine, provided that
such conditions shall not be inconsistent with this Plan. Nothing in the Plan shall be deemed to give any Participant the right
to have such Participant’s ISOs converted into Non-Qualified Options, and no such conversion shall occur until and unless
the Committee takes appropriate action.

 

7.10.       
Cancellation of Options. Except as otherwise expressly provided in the agreement pursuant to which an Option is issued,
the Committee may, in its sole discretion, in cases involving a serious breach of conduct by an employee or former employee, or
activity of a former employee in competition with the business of the Company, cancel any Option, whether vested or not, in whole
or in part. Such cancellation shall be effective as of the date specified by the Committee.

Section
8

Restricted Stock

 

8.1.           
Grant of Restricted Stock. The Committee may award shares of Restricted Stock and determine the purchase price, if
any, therefor, the duration of the restricted period during which the shares are subject to forfeiture or restrictions on transferability,
if any, the conditions, if any, under which the Shares may be forfeited to or repurchased by the Company and any other terms and
conditions of the Awards. The Committee may modify or waive any restrictions, terms and conditions with respect to any Restricted
Stock. Shares of Restricted Stock may be issued for such consideration, if any, as is determined by the Committee, subject to applicable
law.

 

8.2.           
Transferability. Except as set forth in the applicable Award Agreement, Shares of Restricted Stock may not
be sold, assigned, transferred, pledged or otherwise encumbered. Furthermore, the Award of Shares of Restricted Stock may be made
subject to a repurchase right or right of first refusal, with respect to the Shares of Restricted Stock, in favor of the Company
and certain stockholders of the Company upon the occurrence of certain specified events.

 

8.3.           
Evidence of Award. Shares of Restricted Stock shall be evidenced in such manner as the Committee may determine. Any
certificates issued in respect of Shares of Restricted Stock shall be registered in the name of the Participant and, unless otherwise
determined by the Committee, deposited by the Participant, together with a stock power endorsed in blank, with the Company (or
its designee). At the expiration of the restricted period(s), the Company (or such designee) shall deliver the certificates no
longer subject to such restrictions to the Participant.

 

8.4.           
Shareholder Rights. A Participant shall have all the rights of a shareholder with respect to Restricted Stock awarded,
including voting and dividend rights, unless otherwise provided in the Award Agreement.

 

Section
9

Other Stock-Based Awards

 

The Committee shall have the right to grant
other Awards based upon the Common Stock having such terms and conditions as the Committee may determine, including, without limitation,
the grant of Shares based upon certain conditions, the grant of securities convertible into Common Stock and the grant of stock
appreciation rights.

 

Section
10

ADJUSTMENTS UPON CHANGES IN CAPITALIZATION AND “TERMINATING TRANSACTION” EVENTS

 

10.1.         
Upon the occurrence of any of the following events, a Participant’s rights with respect to Awards granted to such
participant hereunder shall be adjusted as hereinafter provided, unless otherwise specifically provided in the Award Agreement:

 

    -7-

     

    

 

10.1.1.   
Recapitalization or Reorganization. Subject to Section 10.1.2 below, if, as a result of any recapitalization, reorganization,
reclassification, stock dividend, stock split, reverse stock split or other similar change in the Company’s capital stock,
the outstanding shares of Stock are increased or decreased or are exchanged for a different number or kind of shares or other securities
of the Company, or additional shares or new or different shares or other securities of the Company or other non-cash assets are
distributed with respect to such Shares or other securities, or, if, as a result of any merger, consolidation or sale of all or
substantially all of the assets of the Company, the outstanding shares of Stock are converted into or exchanged for a different
number or kind of securities of the Company or any successor entity (or a parent or subsidiary thereof), the Committee shall make
an appropriate or proportionate adjustment in (i) the maximum number of shares reserved for issuance under the Plan, (ii) the number
and kind of shares or other securities subject to any then outstanding Awards under the Plan, (iii) the repurchase price per share
subject to each outstanding Award, if any, and (iv) the exercise price and/or exchange price for each share subject to any then
outstanding Options under the Plan, without changing the aggregate exercise price (i.e., the exercise price multiplied by the number
of Options) as to which such Options remain exercisable. The adjustment by the Committee shall be final, binding and conclusive.
No fractional shares of Stock shall be issued under the Plan resulting from any such adjustment, but the Committee in its discretion
may make a cash payment in lieu of fractional shares. The Committee may also adjust the number of shares subject to outstanding
Awards and the exercise price and the terms of outstanding Awards to take into consideration material changes in accounting practices
or principles, extraordinary dividends, acquisitions or dispositions of stock or property or any other event if it is determined
by the Committee that such adjustment is appropriate to avoid distortion in the operation of the Plan, provided that no such adjustment
shall be made in the case of an Incentive Stock Option, without the consent of the grantee, if it would constitute a modification,
extension or renewal of the Option within the meaning of Section 424(h) of the Code.

 

10.1.2.   
Change in Control. Notwithstanding any other provision of the Plan, but subject to the provisions of any particular
Award Agreement, in the event of any Change in Control (as defined below) of the Company, and in anticipation thereof if required
by the circumstances, the Committee, in its sole discretion (and in addition to or in lieu of any actions permitted to be taken
by the Company under the terms of any particular Award Agreement), may, on either an overall or a Participant by Participant basis,
(i) accelerate the exercisability, prior to the effective date of such Change in Control, of any outstanding Options (and/or terminate
the restrictions applicable to any Shares of Restricted Stock), (ii) upon written notice, provide that any outstanding Options
must be exercised, to the extent then exercisable, within a specified number of days after the date of such notice, at the end
of which period such Options shall terminate, (iii) if there is a surviving or acquiring entity, and subject to the consummation
of such Change in Control, cause that entity or an affiliate of that entity to grant replacement Awards having such terms and conditions
as the Committee determines to be appropriate in its sole discretion, upon which replacement the replaced Options or Restricted
Stock shall be terminated or cancelled, as the case may be, (iv) terminate any outstanding Options and make such payments, if any,
therefor (or cause the surviving or acquiring entity to make such payments, if any, therefor) as the Committee determines to be
appropriate in its sole discretion (including, without limitation, with respect to only the then exercisable portion of such Options
based on the Fair Market Value of the underlying Shares as determined by the Board in good faith), upon which termination such
Options shall immediately cease to have any further force or effect, (v) repurchase (or cause the surviving or acquiring entity
to purchase) any Shares of Restricted Stock for such amounts, if any, as the Board determines to be appropriate in its sole discretion
(including, without limitation, an amount with respect to only the vested portion of such Shares (i.e., the portion that is not
then subject to forfeiture or repurchase at a price less than their value), based on the Fair Market Value of such vested portion
as determined by the Board in good faith), upon which purchase the holder of such Shares shall surrender such Shares to the purchaser,
or (vi) take any combination (or none) of the foregoing actions. For purposes of this Plan, a “Change in Control” shall
mean a single transaction or series of related transactions, other than an Initial Public Offering, pursuant to which a person
or persons, other than existing stockholders of the Company (i) acquires capital stock of the Company possessing the voting power
to elect a majority of the Board, (ii) consummates a merger, amalgamation or consolidation with the Company as a result of which
the stockholders of the Company who own common stock or other voting securities prior to such transaction(s) shall own, directly
or indirectly, less than fifty percent (50%) of the voting securities of the surviving entity, or (iii) acquire all or substantially
all of the assets of the Company.

 

    -8-

     

    

 

10.1.3.   
Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, each Award will
terminate immediately prior to the consummation of such proposed action or at such other time and subject to such other conditions
as shall be determined by the Committee.

 

10.2.       
Assumption of Options Upon Certain Events. In connection with a merger or consolidation of an entity with the Company
or the acquisition by the Company of property or stock of an entity, the Committee may grant Awards under the Plan in substitution
for stock and stock based awards issued by such entity or affiliate thereof.

 

10.3.       
No Effect. Except as expressly provided herein, no issuance by the Company of shares of stock of any class, or securities
convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares subject to Options. No adjustments shall be made for dividends paid in cash or in property other
than securities of the Company.

 

10.4.       
Appropriate Adjustments. Upon the happening of any of the events described in Section 10.1 above, the class and aggregate
number of shares set forth in Section 6 hereof that are subject to Options which previously have been or subsequently may be granted
under the Plan shall also be appropriately adjusted to reflect the events described in such subparagraphs. The Committee or the
Board shall determine the specific adjustments to be made under this Section 10 and, subject to Section 3, its determination shall
be conclusive.

the Optionee may exercise the Option for such additional numbers of Shares as have become exercisable pursuant to such schedule.
Notwithstanding the foregoing, the Board may, in its discretion, accelerate the date on which any portion of the Option becomes
exercisable, subject to the requirements of section 409A of the Code if the Option granted hereunder is a Non-Qualified Stock Option.
The foregoing rights are cumulative and may be exercised only before the expiration date set forth on the Signature page of this
Agreement. For purposes of this section 2(a) only, the definition of a Change in Control shall not include a liquidation or dissolution
of the Company.

 

2.            
Purpose and Waiver. The purpose of this Option is to encourage the Optionee to enter into and/or maintain a continuing
and long-term relationship with the Company. It is not a purpose of this Option to reward the Optionee for the completion
of any specific project or of any discrete period of service which may fall between consecutive vesting periods of this Option.
By signing this Agreement, the Optionee hereby waives any claims to any Shares that have not become exercisable pursuant to Section
2(a) of this Agreement as of the date of the termination of the Optionee’s service to the Company.

3.            
Exercise.

 

(a)         
General. Within the limits set forth in Section 2, above, the Option may be exercised from time to time with respect to
all or any part of the Shares as to which it is exercisable at the time; provided, however, that the Option may not be exercised
as to less than 10% of the total number of Shares subject to this Option at any one time, except with respect to the remaining
Shares then purchasable under the Option, if less than 10% of such total number of Shares. No fractional Shares may be purchased
except in combination with a fraction or fractions under another currently exercisable option or options granted under the Plan,
and then only to the extent that such combination equals a full Share. Shares purchased upon exercise of this Option will be subject
to restrictions on transfer and a Right of First Refusal. In addition, the exercise of the Option shall be subject to satisfaction
of all conditions the Board may impose on the exercise of the Option pursuant to this Agreement or the Plan, and any such exercise
shall be effective only after all such conditions have been satisfied.

 

(b)         
Deliveries. To exercise the Option, the Optionee (or other person exercising the Option) must deliver to the Company
the following:

 

(i)                
a completed and signed Notice of Stock Option Exercise, in the form of Attachment A hereto (the “Exercise Notice”).
If the Option is being exercised pursuant to Section 8.1 of the Plan by a person other than the Optionee, the Exercise Notice must
be accompanied by proof of the right of such person to exercise the Option and such other pertinent information as the Company
deems necessary;

 

(ii)          
payment in full of the aggregate Exercise Price of the Shares being purchased:

 

(A)       in
cash or by check made payable to the order of the Company;

 

(B)       subject
to Section 3(c), below, by delivery of shares of Common Stock having an aggregate Fair Market Value on the date of exercise equal
to the aggregate Exercise Price;

 

(C)       subject
to Section 3(c), below, by a combination of cash, check and/or shares of Common Stock;

 

(D)       at
the discretion of the Administrator, by delivery of a full- recourse promissory note bearing interest (at no less than such rate
as shall then preclude the imputation of interest under the Code) and payable upon such terms as presented by the Administrator;

 

(E)        subject
to Section 3(c), below, if previously approved by the Board, by a combination of cash, check, shares of Common Stock and a promissory
note in accordance with the terms of the Plan; or

 

    -12-

     

    

 

(F)        if
the Common Stock is then traded on a national securities exchange or on the NASDAQ National Market (or successor trading system),
by delivery of an irrevocable undertaking, satisfactory in form and substance to the Company, by a creditworthy securities broker
to sell such Shares and to deliver promptly to the Company sufficient funds to pay the aggregate Exercise Price and any applicable
withholding taxes, or delivery by the Optionee to the Company of a copy of irrevocable instructions, satisfactory in form and substance
to the Company, to a creditworthy securities broker to sell such Shares and to deliver promptly to the Company sufficient funds
to pay the aggregate Exercise Price and any applicable withholding or employment taxes; or

 

(G)       if
the Common Stock is then traded on a national securities exchange or on the NASDAQ National Market (or successor trading system),
by delivery by the Optionee to the Company of a copy of irrevocable instructions, satisfactory in form and substance to the Company,
to pledge such Shares to a securities broker or lender approved by the Company as security for a loan, and to deliver promptly
to the Company sufficient funds to pay the aggregate Exercise Price and any applicable withholding or employment taxes;

 

(c)         
Limitations on Payment by Delivery of Common Stock. If clause (B) or (C) or (D) of Section 3(b)(ii) is applicable, and if
the Optionee wishes to deliver shares of Common Stock held by the Optionee (“Old Stock”) to the Company in full or
partial payment of the aggregate Exercise Price, then:

 

(i)            
the certificate or certificates representing such Old Stock shall be duly endorsed for transfer to the Company and such
Old Stock shall be free of all transfer restrictions, liens, encumbrances and other legal or equitable interests;

 

(ii)           
if the Old Stock so delivered is subject to restrictions or limitations imposed by agreement between the Optionee and the
Company, an equivalent number of Shares shall be subject to all restrictions and limitations applicable to the Old Stock to the
extent that the Optionee paid for the Shares by delivery of Old Stock, in addition to any restrictions or limitations imposed by
this Agreement; and

 

(iii)          
notwithstanding any provision of this Agreement to the contrary, the Optionee may not pay any part of the aggregate Exercise
Price hereof by transferring Old Stock to the Company (A) unless such Old Stock has been owned by the Optionee free of any substantial
risk of forfeiture for at least six (6) months and (B) the Board determines that payment of the aggregate Exercise Price by delivery
of such Old Stock will not result in a charge to earnings for financial accounting purposes.

 

(d)         
Share Certificate(s).

 

(i)            
Delivery. Subject to Section 3(e), below, the Company shall deliver a certificate or certificates representing the
Shares to the Treasurer of the Company, as custodian (the “Custodian”) as soon as practicable after receipt of the
deliveries specified in Section 3(b), above. Such certificate or certificates shall be registered in the name of the person or
persons so exercising this Option. The certificate or certificates so delivered to the Custodian shall be held by the Custodian
for the benefit and in favor of the Optionee, subject to the provisions of this Section 3(d). Notwithstanding the escrow, the Optionee
shall retain the right to vote and enjoy all other rights and incidents of ownership of the Shares represented by said certificates.
The Custodian shall issue a receipt to the Optionee evidencing the delivery of the stock certificates and transfer powers. The
Custodian shall arrange to keep any stock certificates and stock transfer powers delivered to him under this Section 3(d) in a
secure place and shall keep true and accurate records of all such certificates and powers.

 

    -13-

     

    

 

(ii)           
Concerning the Custodian. The Company shall indemnify and hold harmless the Custodian against any and all costs or
expenses (including attorneys’ fees expenses), judgments, fines, losses, claims, damages, liabilities and amounts paid in
settlement in connection with any claim, action, suit, proceeding or investigation arising out of or pertaining to this Agreement.
Any person succeeding to the office of Treasurer shall succeed to and assume the rights and obligations of Custodian hereunder.

 

(iii)          
Release. At such times as may be authorized by the Board, upon the written request of the Optionee, the Custodian
shall deliver to the Optionee stock certificates and stock transfer powers executed by the Optionee representing such number of
Shares. The Optionee shall execute such additional stock transfer powers and take such additional action as the Custodian shall
request to enable the Custodian to maintain possession of stock certificates and, stock transfer powers duly executed by the Optionee
representing the remainder of the Shares, if any.

 

(e)         
Legal and Regulatory Matters. The Plan, this Agreement, the Option and the obligation of the Company to sell and
deliver the Shares upon exercise of the Option are and shall be subject to (i) all applicable laws, government regulations and
rules and (ii) all applicable regulations and rules adopted by the Board in accordance with the Plan. Without limiting the generality
of the foregoing, no Shares shall be issued upon the exercise of this Option unless and until the Company has determined in its
sole discretion that:

 

(i)            
The Company and the Optionee have taken all actions required to register the Shares under the Securities Act of 1933, as
amended, or any successor statute (the “Securities Act”), or to perfect an exemption from the registration requirements
of the Securities Act;

 

(ii)           
Any applicable listing requirements of any stock exchange or other securities market on which the Common Stock is listed
have been satisfied; and

 

(iii)          
All other applicable provisions of federal and state law have been satisfied.

 

(f)          
The Company may require, as a condition to the exercise of this Option, that Optionee agree to be bound by any shareholders
agreement among all or certain shareholders of the Company that may then be in effect, or certain provisions of any such agreement
that may be specified by the Company, in addition to the provisions of Sections 7, 8 and 9 hereof.

 

    -14-

     

    

 

4.            
Termination.

 

(a)         
Termination of Service. Except as otherwise extended by the Board, upon the termination of the service of the Optionee,
the Optionee’s Option shall expire on the earliest of the following occasions:

 

(i)            
the date that is three months after the voluntary termination of the Optionee’s service or the termination of the
Optionee’s service by the Company (or by an Subsidiary) other than for Cause;

 

(ii)           
the date of the termination of the Optionee’s service by the Company (or by an Subsidiary) for Cause;

 

(iii)          
the date one year after the termination of the Optionee’s service by reason of Disability; or

 

(iv)         
the date one year after the termination of the Optionee’s service by reason of the Optionee’s death.

 

The Optionee may exercise all or any part of the Optionee’s
Option at any time before the expiration of such Option under this Section 4, but only to the extent that such Option had become
exercisable before the Optionee’s service terminated (or became exercisable as a result of the termination) and the underlying
Shares had vested before the Optionee’s service terminated (or vested as a result of the termination). The balance of such
Option shall lapse when the Optionee’s service terminates. In the event that the Optionee dies during the Optionee’s
service, or after the termination of the Optionee’s service but before the expiration of the Optionee’s Option, all
or part of such Option may be exercised (prior to expiration) by the executors or administrators of the Optionee’s estate
or by any person who has acquired such Option directly from the Optionee by beneficiary designation, bequest or inheritance, but
only to the extent that such Option had become exercisable before the Optionee’s service terminated (or became exercisable
as a result of the termination) and the underlying Shares had vested before the Optionee’s service terminated (or vested
as a result of the termination).

 

(b)         
Termination on Change in Control. Except as otherwise determined by the Board, in the case of a Change in Control,
this Option shall terminate on the effective date of such transaction or event, unless provision is made in such transaction in
the sole discretion of the parties thereto for the assumption of this Option or the substitution for this Option of a new stock
option of the successor person or entity or a parent or subsidiary thereof, with appropriate adjustment as to the number and kind
of shares and the per share exercise price, as provided in Section 13 of this Agreement. In the event of any transaction that will
result in such termination, the Company shall give to the Optionee written notice thereof at least ten (10) days prior to the effective
date of such transaction. Until such effective date, the Optionee may exercise any portion of this Option that is or becomes vested
on or prior to such effective date, but after such effective date the Optionee may not exercise this Option unless it is assumed
or substituted by the successor entity (or a parent or subsidiary thereof) as provided above.

 

    -15-

     

    

 

(c)         
Termination of Employment; Voting Trust. If the Optionee ceases to be an employee or consultant of the Company for
any reason, including death or disability, (such Optionee is a “Terminated Optionee” for purposes of this section)
all of the Shares held by such Terminated Optionee or his transferees as a result of exercising all or any portion of this Option,
at the election of the Company, shall be subject to the following procedures:

 

(i)            
the Company shall have the right and option (“Purchase Option”) to purchase from the Optionee and his transferees
(the “Seller”), free and clear of all liens and encumbrances, any or all of the Shares for a purchase price equal to
the Exercise Price paid for such Shares (“Option Price”). The Company may exercise the Purchase Option by delivering
or mailing to the Seller a written notice of exercise of the Purchase Option, within ninety (90) days after the termination date
of the employment or consultancy of such Terminated Optionee. Such notice shall specify the number of Shares to be purchased and
the aggregate Option Price for such Shares. If and to the extent the Purchase Option is not so exercised by the giving of such
a notice within such ninety (90) day period, the Purchase Option shall automatically expire and terminate effective upon the expiration
of such ninety (90) day periodAfter the time at which any Shares are required to be delivered to the Company for transfer to
the Company pursuant to this clause (i) above, the Company shall not pay any dividend to the holder thereof on account of such
Shares or permit the holder thereof to exercise any of the privileges or rights of a stockholder with respect to such Shares, but
shall, in so far as permitted by law, treat the Company as the owner of such The Option Price may be payable, at the option of
the Company, in cancellation of all or a portion of any outstanding indebtedness of the Seller to the Company or in cash (by check)
or both Shares.

 

(ii)           
in the event that the Company does not exercise the Purchase Option, the Shares shall automatically put into a voting trust
(the “Voting Trust”), with a trustee to be designated by the Company. The Optionee for himself or herself agrees
to execute a Voting Trust Agreement in form and substance substantially as set forth at Attachment B attached hereto. Such Shares
shall be held by the Voting Trust for the benefit of the Terminated Optionee, and all voting rights shall be granted to one or
more voting trustees to be designated solely by the Board. If determined by the Board in its sole discretion, Optionee may also
be required to execute an irrevocable proxy in connection with the provisions of this Section 4(c)(ii).

 

5.            
No Rights as Shareholder. The Optionee (or any other person entitled to exercise the Option) shall not be entitled
to any rights as a shareholder of the Company with respect to any Shares issuable upon exercise of this Option until such Shares
shall have been registered on the stock transfer books of the Company in the name of the Optionee (or such other person).

 

6.            
Notice of Premature Disposition. If this Option is intended to qualify as an Incentive Stock Option, as provided
on the signature page of this Agreement, then if, within the later of (2) two years from the Grant Date or within one (1) year
after the transfer of Shares to the Optionee upon exercise of the Option, the Optionee makes a disposition (as defined in Section
424(c) of the Code) of any Shares, the Optionee shall notify the Treasurer of the Company within ten (10) days after such disposition.

 

    -16-

     

    

 

7.            
Right of First Refusal; Drag Along Right.

 

(a)         
Right of First Refusal. If the Optionee shall propose to transfer any Option Shares held by him to any Person (a
 “Transferee”), such proposed transfer shall be conditioned upon the following:

 

(i)            
The Optionee shall not transfer any Option Shares unless the Optionee has owned such shares for a period of at least six
(6) months on the date of transfer. Any transfer of Option Shares owned by the Optionee for less than six (6) months on the date
of transfer shall be null and void.

 

(ii)           
The Optionee (the “Offeror”) shall offer to the Company or the Company’s designee(s) the Option Shares
which it desires to sell, transfer or convey (the “Offered Securities”), at the same price and on the same terms that
the Optionee intends to sell, transfer or convey the Offered Securities to the Transferee; provided that the Company or its designee(s)
shall have no rights to acquire the Offered Securities unless all of the Offered Stock is acquired. Such offer shall be made by
a written notice (the “Notice of Proposed Transfer”) delivered to the Company not less than sixty (60) days prior to
the proposed sale, transfer or conveyance. Such notice shall set forth the identity of the Transferee, the price and other terms
and conditions of the proposed sale or transfer and such other information as the Company or its designee(s) shall reasonably request,
including but not limited to the provisions of Section 7(b) hereof.

 

(iii)          
If the Company or its designee(s) do not accept the offer made by the Offeror with respect to all of the Offered Securities
within sixty (60) days following the Company’s receipt of the Notice of the Proposed Transfer, then the Offeror shall have
the right for a period of thirty (30) days following the aforementioned sixty (60) day period to sell, transfer or convey such
Offered Securities, but only to the Transferee, at not less than the price, and upon terms not more favorable to the Transferee
that were contained in the Notice of Proposed.

 

(b)         
Drag Along Rights. If, upon the approval of the Board of Directors of the Company, the holders of shares equal to
a majority of the issued and outstanding Common Stock, determined on an as converted basis (i.e., assuming the conversion of all
shares of capital stock which can be converted into Common Stock at the time of the determination, into Common Stock), elect to
effect a sale of all of their shares of capital stock (the “Subject Shares”), the Optionee shall sell all Option Shares
held by him or her on the terms and conditions approved by such other selling stockholders; provided, however, that the Option
Shares being sold by the Optionee are sold for the same price and upon the same terms and conditions in all material respects as
those applicable to the Subject Shares being sold by such other selling stockholders, adjusting for the conversion of all shares
of capital stock which can be converted into Common Stock. The Optionee will take all action necessary and desirable in connection
with the consummation of the sale of the Option Shares in connection with a sale of the Subject Shares, including, without limitation,
execution and delivery of agreements relating to such sale of Subject Shares and the Option Shares. The Optionee will bear its
pro rata share of the cost of any sale of Subject Shares or other equity securities pursuant to a sale of Subject Shares and the
Option Shares to the extent such costs are incurred for the benefit generally of all stockholders of the Company and are not otherwise
paid by the Company or the acquiring party. Costs incurred by stockholders of Company on their own behalf will not be considered
costs of the transaction hereunder. The Company shall have no duty or obligation to disclose to the Optionee, and the Optionee
shall have no right to be advised of, any material information regarding the Company or any of its subsidiaries or affiliates,
at any time prior to, upon or in connection with the exercise of the rights hereunder by the Company.

 

    -17-

     

    

 

(c)         
This Section 7 shall terminate upon an underwritten public offering pursuant to an effective registration statement under
the Securities Act, covering the offer and sale by the Company of Common Stock.

 

8.            
Restrictions on Transfer.

 

(a)         
No Transfer of Options. This Option is not transferable by the Optionee except by will or the laws of descent and
distribution, and is exercisable, during the Optionee’s lifetime, only by the Optionee. Notwithstanding the foregoing, if
this Option is a Non-Qualified Stock Option, such Non- Qualified Stock Option is transferable to the extent permitted by the Plan.

 

(b)         
No Transfer of Shares. The Optionee shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose of,
by operation of law or otherwise (collectively “transfer”), any of the Shares, or any interest therein, unless such
transfer is made in compliance with the provisions of this Agreement.

 

(c)         
Permitted Transfers of Shares. The Optionee shall have the right to make Permitted Transfers of Shares. For purposes
of this Agreement, “Permitted Transfer” shall mean any transfer of all or any portion of the Optionee’s Shares
by will or the laws of descent and distribution and any transfer by the Optionee during his or her lifetime of all or any portion
of his or her Shares to or for the benefit of any spouse, child or grandchild (including any natural born, adopted or step-child
or step- grandchild) of the Optionee, or to a trust for the benefit of the Optionee and/or any of the foregoing or to a partnership
or limited liability company, the partners or members of which include only the Optionee and/or any of the foregoing or any other
person or entity determined by the Board; provided, however, that it shall be a condition of each such Permitted Transfer
that (i) the transferee agrees to be bound by the terms of this Agreement and (ii) the Optionee has complied with all applicable
laws in connection with such Permitted Transfer. For purposes of this Agreement, (a) any donee or transferee of the Optionee’s
Shares shall be treated as the “Optionee,” and (b) notwithstanding the foregoing clause, the circumstances or events
giving rise to any forfeiture or repurchase right shall be determined with respect to the original “Optionee” who was
first issued such Shares and transferred them to the transferee, and the transferee shall be subject to forfeiture or a repurchase
right upon such circumstance or event. For purposes of an example of the foregoing clause (b) and not in any way as a limitation,
if a termination of employment gives rise to a repurchase right with respect to Shares held by a transferee, it shall be the termination
of the original Shareholder’s employment that creates the repurchase right and not the termination of employment of such
transferee.

 

    -18-

     

    

 

 

(d)              
Effect of Prohibited Transfer of Shares. Any transfer of Shares in violation of this Agreement shall be void. The
Company shall not be required (i) to transfer on its books any of the Shares which shall have been transferred in violation of
this Agreement or (ii) to treat as the owner of such Shares or pay dividends to any transferee to whom any such Shares shall have
been so transferred.

 

9.               
Securities Law Restrictions on Resale.

 

(a)              
Optionee’s Representations and Agreements. The Optionee represents and agrees that (i) unless and until registered
under the Securities Act, the Shares will be of an illiquid nature and will be deemed to be “restricted securities”
for purposes of the Securities Act; (ii) the Shares to be acquired upon exercising this Option will be acquired for investment,
and not with a view to the sale or distribution thereof, and (iii) such Shares may not be sold except in compliance with the registration
requirements of the Securities Act or an exemption therefrom.

 

(b)              
Legends on Certificates. Unless the Shares have been registered under the Securities Act, each certificate evidencing
any of the Shares shall bear a legend referring to the restrictions on transfer imposed by the Securities Act, and any applicable
state securities laws, as well as a legend to the following effect:

 

“THE SHARES OF STOCK
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS UPON TRANSFER AND MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED,
HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE WITH AND SUBJECT TO ALL OF THE TERMS AND CONDITIONS OF A CERTAIN STOCK
OPTION AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED OWNER OF THIS CERTIFICATE AND THE COMPANY’S 2011 EQUITY INCENTIVE
PLAN. THE COMPANY WILL FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER OF THIS CERTIFICATE UPON WRITTEN REQUEST AND WITHOUT CHARGE.”

 

(c)              
Removal of Legends. If, in the opinion of counsel to the Company, any legend placed on a stock certificate representing
Shares issued under this Agreement is no longer required, then the holder of such certificate shall be entitled to exchange such
certificate for a certificate representing the same number of Shares but without such legend.

 

(d)              
Lock-up Agreement. The Optionee agrees that, in the event that the Company effects any underwritten public offering
of Common Stock registered under the Securities Act, neither the Shares nor any interest in the Shares may be sold, offered for
sale, pledged or otherwise disposed of, directly or indirectly (including through the granting of options or any hedging transactions),
without the prior written consent of the managing underwriter(s) of the offering, for the same period of time after the execution
of an underwriting agreement in connection with such offering, and on the same terms, that all of the Company’s then directors
and executive officers agree to be restricted.

 

    -19- 

     

    

 

10.             
No Retention Rights. Nothing in the Plan, the Option or this Agreement confers upon the Optionee any right to continue
in the service of the Company for any period of specific duration or shall be construed to interfere with or otherwise restrict
in any way the rights of the Company or of the Optionee, which rights are expressly reserved by each, to terminate the Optionee’s
service at any time and for any reason, with or without cause.

 

11.             
Taxes. As a condition to the issuance of Shares upon exercise of this Option, the Optionee hereby agrees that, if
the Company in its discretion determines that it is or could be obligated to withhold any tax in connection with the exercise of
this Option, or in connection with the transfer of, or the lapse of restrictions on, any Shares or other property acquired pursuant
to the Option, the Company may, in its discretion, withhold the appropriate amount of tax (a) in cash from the Optionee’s
wages or other remuneration or (b) in kind from the Shares or other property otherwise deliverable to the Optionee on exercise
of this Option. The Optionee further agrees that, if the Company does not withhold an amount sufficient to satisfy the withholding
obligation of the Company, the Optionee will on demand, and as a condition to the issuance of Shares upon the exercise of this
Option, make reimbursement in cash for the amount underwithheld or, if permitted by the Board, provide such cash or other security
as the Board deems adequate to meet the liability or potential liability of the Company for the withholding of tax, and to augment
such cash or other security from time to time in any amount reasonably deemed necessary by the Board to preserve the adequacy of
such cash or other security.

 

12.             
Amendments. The Board may at any time or times amend the Plan, the Option granted hereunder, or this Agreement for
the purpose of satisfying the requirements of any changes in applicable laws or regulations or for any other purpose which at the
time may be permitted by law. No termination, amendment of the Plan, amendment of the Option or this Agreement shall, without the
Optionee’s consent, materially adversely affect the Optionee’s rights under the Option or this Agreement. Notwithstanding
the foregoing, this Agreement shall be amended as required by Section 15(g) below to the extent required by regulatory or statutory
guidance.

 

13.             
Adjustments for Stock Splits, Stock Dividends, Etc. If from time to time while this Agreement remains in force and
effect there is any stock split-up, stock dividend, stock distribution or other reclassification of the Common Stock of the Company,
(a) any and all new, substituted or additional securities to which the Optionee is entitled by reason of his ownership of Shares
shall be immediately subject to the restrictions on transfer and other provisions of this Agreement in the same manner and to the
same extent as such Shares and (b) appropriate adjustment shall be made to the Exercise Price, subject to compliance with section
409A of the Code, if applicable. Except as is expressly provided in the Plan with respect to certain changes in the capitalization
of the Company, no adjustment shall be made for dividends or similar rights for which the record date is prior to such date of
exercise.

 

    -20- 

     

    

 

14.             
Consistency with Plan. If there is any inconsistency between the provisions of this Agreement and the provisions
of the Plan, the latter shall control.

 

15.             
Miscellaneous.

 

(a)              
Severability; Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the
State of Delaware without regard to conflict of law principles

 

(b)              
Injunctive Relief. It is acknowledged that it will be impossible to measure the damages that would be suffered by
the Company if the Optionee fails to comply with the provisions of this Agreement and that, in the event of any such failure, the
Company will not have an adequate remedy at law. The Company shall, therefore, be entitled to obtain specific performance of each
of the Optionee’s obligations hereunder and to obtain immediate injunctive relief. The Optionee shall not urge, as a defense
to any proceeding for such specific performance or injunctive relief, that the Company has an adequate remedy at law.

 

(c)              
Binding Effect. This Agreement shall be binding upon and inure to the benefit of the parties and their respective
heirs, executors, administrators, successors and permitted assigns.

 

(d)              
Notices. All notices required or permitted hereunder shall be in writing and be effective upon personal delivery,
upon deposit with the United States Post Office, by registered or certified mail, postage prepaid, or upon deposit with a recognized

Restricted Stock Agreement

under the 2011 Equity Incentive Plan

 

Incorporated Terms and Conditions

 

1.                 
Issuance of Shares. On the terms and conditions set forth in this Agreement, the Company grants to the Shareholder on the
Award Date, at the price per share set forth on the signature page of this Agreement, the number of shares of the Company’s
Common Stock set forth on said signature page (the “Shares”). The award of the Shares is made pursuant to and is governed
by the Plan (including any applicable sub-plan), the terms of which are incorporated into this Agreement by this reference. To
the extent there is any inconsistency between the terms of the Plan and this Agreement, the terms of the Plan shall control. Unless
the context otherwise requires, capitalized terms used herein without definitions shall have the respective meanings assigned to
them in the Plan. By signing this Agreement, the Shareholder acknowledges receipt of a copy of the Plan.

 

2.                 
Award Restrictions. The Shares covered by this restricted stock award shall be subject to the vesting schedule set forth
on the signature page. During the restriction period, the Shares covered by the restricted stock award are not transferable by
the Shareholder by means of sale, assignment, exchange, pledge, or otherwise, except by will or the laws of descent and distribution.
The naming of a designated beneficiary under the Plan does not constitute a transfer.

 

3.                 
Investment Representations. In connection with the issuance of the Shares contemplated by Section 1 above, the Shareholder
hereby represents and warrants to the Company as follows:

 

(a)              
The Shareholder is receiving the Shares for the Shareholder’s own account for investment only, and not with a view
to, or for sale in connection with, any distribution of the Shares in violation of the Securities Act, or any rule or regulation
under the Securities Act.

 

(b)              
The Shareholder has had such an opportunity as he or she has deemed adequate to obtain from the Company such information
as is necessary to permit him or her to evaluate the merits and risks of the Shareholder’s investment in the Company and
has consulted with the Shareholder’s own advisers with respect to the Shareholder’s investment in the Company.

 

(c)              
The Shareholder has sufficient experience in business, financial and investment matters to be able to evaluate the risks
involved in the purchase of the Shares and to make an informed investment decision with respect to such purchase.

 

(d)              
The Shareholder can afford a complete loss of the value of the Shares and is able to bear the economic risk of holding such
Shares for an indefinite period.

 

(e)              
The Shareholder understands that the Shares are not registered under the Securities Act (it being understood that the Shares
are being issued and sold in reliance on the exemption provided in Rule 701 thereunder) or any applicable state securities or “blue
sky” laws and may not be sold or otherwise transferred or disposed of in the absence of an effective registration statement
under the Act and under any applicable state securities or “blue sky” laws (or exemptions from the registration requirements
thereof). The Shareholder further acknowledges that certificates representing the Shares will bear restrictive legends reflecting
the foregoing.

 

     

     

    

 

4.                 
Restrictions on Transfer.

 

(a)              
No Transfer of Shares. The Shareholder shall not sell, assign, transfer, pledge, hypothecate or otherwise dispose
of, by operation of law or otherwise (collectively “transfer”), any of the Shares, or any interest therein, unless
such transfer is made in compliance with the provisions of this Agreement.

 

(b)              
Permitted Transfers of Shares. The Shareholder shall have the right to make Permitted Transfers of Shares. For purposes
of this Agreement, “Permitted Transfer” shall mean any transfer of all or any portion of the Shareholder’s Shares
by will or the laws of descent and distribution and any transfer by the Shareholder during his or her lifetime of all or any portion
of his or her Shares to or for the benefit of any spouse, child or grandchild (including any natural born, adopted or step-child
or step-grandchild) of the Shareholder, or to a trust for the benefit of the Shareholder and/or any of the foregoing or to a partnership
or limited liability company, the partners or members of which include only the Shareholder and/or any of the foregoing or any
other person or entity determined by the Board; provided, however, that it shall be a condition of each such Permitted Transfer
that (i) the transferee agrees to be bound by the terms of this Agreement and (ii) the Shareholder has complied with all applicable
laws in connection with such Permitted Transfer. For purposes of this Agreement, (a) any donee or transferee of the Shareholder’s
Shares shall be treated as the “Shareholder,” and (b) notwithstanding the foregoing clause, the circumstances or events
giving rise to any forfeiture or repurchase right shall be determined with respect to the original “Shareholder” who
was first issued such Shares and transferred them to the transferee, and the transferee shall be subject to forfeiture or a repurchase
right upon such circumstance or event. For purposes of an example of the foregoing clause (b) and not in any way as a limitation,
if a termination of employment gives rise to a repurchase right with respect to Shares held by a transferee, it shall be the termination
of the original Shareholder’s employment that creates the repurchase right and not the termination of employment of such
transferee.

 

(c)              
Effect of Prohibited Transfer of Shares. Any transfer of Shares in violation of this Agreement shall be void. The
Company shall not be required (i) to transfer on its books any of the Shares which shall have been transferred in violation of
this Agreement or (ii) to treat as the owner of such Shares or pay dividends to any transferee to whom any such Shares shall have
been so transferred.

 

5.                 
Cancellation of Unvested Shares; Repurchase Right; Voting Trust.

 

(a)              
Cancellation of Unvested Shares. Upon the termination of the Shareholder’s services with the Company (or an
Affiliate), no further portion of the Restricted Shares shall become vested pursuant to this Agreement and all unvested Restricted
Shares shall be cancelled and forfeited effective as of the date that such services are terminated. .

 

(b)              
Repurchase of Vested Shares.

 

     

     

    

 

(i)                
Repurchase Right. Upon the termination of the Shareholder’s services with the Company (or an Affiliate), the
Company or its assigns shall have the right and option to repurchase all or any portion of the Shares held by the Shareholder that
have vested (the “Vested Restricted Shares”). The purchase and sale arrangements contemplated by the preceding sentences
of this Section 5(b)(i) are referred to herein as the “Vested Share Repurchase.” The per share purchase price of the
Vested Restricted Shares subject to the Vested Share Repurchase (the “Vested Shares Repurchase Price”) shall be the
Fair Market Value of such Vested Restricted Shares as of the date of the award of such shares, as determined by the Board of Directors,
in its sole discretion..

 

(ii)             
Closing Procedure. The Company or its assigns shall effect the Vested Share Repurchase by delivering or mailing to
the Shareholder written notice within ninety (90) days after the termination of service, specifying a date within such ninety day
period in which the Vested Share Repurchase shall be effected. Upon such notification, the Shareholder shall promptly surrender
to the Company any certificates representing the Shares being purchased, together with a duly executed stock power for the transfer
of such Shares to the Company or the Company’s assignee or assignees. Upon the Company’s or its assignee’s receipt
of the certificates from the Shareholder, the Company or its assignee or assignees shall deliver to him, her or them a check for
the applicable Repurchase Price (as determined by Section 5(b)(i)) of the Shares being purchased, provided, however, that
the Company may pay the applicable Repurchase Price (as determined by Section 5(b)(i) above) for such Shares by offsetting and
canceling any indebtedness then owed by the Shareholder to the Company. At such time, the Shareholder shall deliver to the Company
the certificate or certificates representing the Shares so repurchased, duly endorsed for transfer, free and clear of any liens
or encumbrances. The Repurchase right shall survive and remain in effect as to the Vested Restricted Shares under Section 5(b)
following and notwithstanding any public offering by or merger or other transaction involving the Company. Certificates representing
such Shares shall bear legends to such effect.

 

(iii)           
Voting Trust. Upon the termination of the Shareholder’s services with the Company (or an Affiliate, the Shares
shall automatically put into a voting trust (the “Voting Trust”), with a trustee to be designated by the Company.
The Shareholder for himself or herself agrees to execute a Voting Trust Agreement in form and substance substantially as set forth
at Exhibit B attached hereto. Such Shares shall be held by the Voting Trust for the benefit of the Shareholder, and all
voting rights shall be granted to one or more voting trustees to be designated solely by the Board of the Company. If determined
by the Board in its sole discretion, the Shareholder may also be required to execute an irrevocable proxy in connection with the
provisions of this Section 5(b)(iii).

 

6.                 
Right of First Refusal; Drag Along Right .

 

(a)              
Right of First Refusal. If the Shareholder shall propose to transfer any Shares held by him to any Person (a “Transferee”),
such proposed transfer shall be conditioned upon the following:

 

(i)              
The Shareholder shall not transfer any Shares unless the Shareholder has owned such shares for a period of at least six
(6) months on the date of transfer. Any transfer of Shares owned by the Shareholder for less than six (6) months on the date of
transfer shall be null and void.

 

     

     

    

 

(ii)             
The Shareholder (the “Offeror”) shall offer to the Company or the Company’s designee(s) the Shares which
it desires to sell, transfer or convey (the “Offered Securities”), at the same price and on the same terms that the
Shareholder intends to sell, transfer or convey the Offered Securities to the Transferee; provided that the Company or its designee(s)
shall have no rights to acquire the Offered Securities unless all of the Offered Stock is acquired. Such offer shall be made by
a written notice (the “Notice of Proposed Transfer”) delivered to the Company not less than sixty (60) days prior to
the proposed sale, transfer or conveyance. Such notice shall set forth the identity of the Transferee, the price and other terms
and conditions of the proposed sale or transfer and such other information as the Company or its designee(s) shall reasonably request,
including but not limited to the provisions of Section 6(b) hereof.

 

(iii)            
If the Company or its designee(s) do not accept the offer made by the Offeror with respect to all of the Offered Securities
within sixty (60) days following the Company’s receipt of the Notice of the Proposed Transfer, then the Offeror shall have
the right for a period of thirty (30) days following the aforementioned sixty (60) day period to sell, transfer or convey such
Offered Securities, but only to the Transferee, at not less than the price, and upon terms not more favorable to the Transferee
that were contained in the Notice of Proposed Transfer.

 

(b)              
Drag Along Rights. If, upon the approval of the Board of Directors of the Company, the holders of shares equal to
a majority of the issued and outstanding Common Stock, determined on an as converted basis (i.e., assuming the conversion of all
shares of capital stock which can be converted into Common Stock at the time of the determination, into Common Stock), elect to
effect a sale of all of their shares of capital stock (the “Subject Shares”), the Shareholder shall sell all Shares
held by him or her on the terms and conditions approved by such other selling stockholders; provided, however, that the Shares
being sold by the Shareholder are sold for the same price and upon the same terms and conditions in all material respects as those
applicable to the Subject Shares being sold by such other selling stockholders, adjusting for the conversion of all shares of capital
stock which can be converted into Common Stock. The Shareholder will take all action necessary and desirable in connection with
the consummation of the sale of the Shares in connection with a sale of the Subject Shares, including, without limitation, execution
and delivery of agreements relating to such sale of Subject Shares and the Shares. The Shareholder will bear its pro rata share
of the cost of any sale of Subject Shares or other equity securities pursuant to a sale of Subject Shares and the Shares to the
extent such costs are incurred for the benefit generally of all stockholders of the Company and are not otherwise paid by the Company
or the acquiring party. Costs incurred by stockholders of Company on their own behalf will not be considered costs of the transaction
hereunder. The Company shall have no duty or obligation to disclose to the Shareholder, and the Shareholder shall have no right
to be advised of, any material information regarding the Company or any of its subsidiaries or affiliates, at any time prior to,
upon or in connection with the exercise of the rights hereunder by the Company.

 

(c)              
This Section 6 shall terminate upon an underwritten public offering pursuant to an effective registration statement under
the Securities Act, covering the offer and sale by the Company of Common Stock.

 

     

     

    

 

7.                 
Securities Law Restrictions on Resale.

 

(a)              
Shareholder’s Representations and Agreements. The Shareholder represents and agrees that (i) unless and until
registered under the Securities Act, the Shares will be of an illiquid nature and will be deemed to be “restricted securities”
for purposes of the Securities Act; (ii) the Shares will be acquired for investment, and not with a view to the sale or distribution
thereof, and (iii) such Shares may not be sold except in compliance with the registration requirements of the Securities Act or
an exemption therefrom.

 

(b)              
Legends on Certificates. Unless the Shares have been registered under the Securities Act, each certificate evidencing
any of the Shares shall bear a legend referring to the restrictions on transfer imposed by the Securities Act, and any applicable
state securities laws, as well as a legend to the following effect:

 

“THE SHARES OF STOCK
REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS UPON TRANSFER AND MAY NOT BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED,
HYPOTHECATED OR OTHERWISE DISPOSED OF EXCEPT IN ACCORDANCE WITH AND SUBJECT TO ALL OF THE TERMS AND CONDITIONS OF A CERTAIN RESTRICTED
STOCK AGREEMENT BETWEEN THE COMPANY AND THE REGISTERED OWNER OF THIS CERTIFICATE AND THE COMPANY’S 2011 EQUITY INCENTIVE
PLAN. THE COMPANY WILL FURNISH A COPY OF SUCH AGREEMENT TO THE HOLDER OF THIS CERTIFICATE UPON WRITTEN REQUEST AND WITHOUT CHARGE.”

 

(c)              
Removal of Legends. If, in the opinion of counsel to the Company, any legend placed on a stock certificate representing
Shares issued under this Agreement is no longer required, then the holder of such certificate shall be entitled to exchange such
certificate for a certificate representing the same number of Shares but without such legend.

 

(d)              
Lock-up Agreement. The Shareholder agrees that, in the event that the Company effects any underwritten public offering
of Common Stock registered under the Securities Act, neither the Shares nor any interest in the Shares may be sold, offered for
sale, pledged or otherwise disposed of, directly or indirectly (including through the granting of options or any hedging transactions),
without the prior written consent of the managing underwriter(s) of the offering, for the same period of time after the execution
of an underwriting agreement in connection with such offering, and on the same terms, that all of the Company’s then directors
and executive officers agree to be restricted.

 

8.                 
No Retention Rights. Nothing in the Plan or this Agreement confers upon the Shareholder any right to continue in
the service of the Company for any period of specific duration or shall be construed to interfere with or otherwise restrict in
any way the rights of the Company or of the Shareholder, which rights are expressly reserved by each, to terminate the Shareholder’s
service at any time and for any reason, with or without cause.

 

9.                 
Section 83(b) Election and Withholding of Taxes. The Participant shall provide the Company with a copy of any timely
election made pursuant to Section 83(b) of the Internal Revenue Code or similar provision of state law (collectively, an “83(b)
Election”), a form of which is attached hereto as Exhibit A. If the Participant makes a timely 83(b) Election, the Participant
shall immediately pay the Company the amount necessary to satisfy any applicable foreign, federal, state, and local income and
employment tax withholding obligations. If the Grantee does not make a timely 83(b) Election, the Participant shall, as Restricted
Shares shall vest or at the time withholding is otherwise required by any applicable law, pay the Company the amount necessary
to satisfy any applicable foreign, federal, state, and local income and employment tax withholding obligations. The Participant
hereby represents that he or she understands (a) the contents and requirements of the 83(b) Election, (b) the application of Section
83(b) to the receipt of the Shares by the Participant pursuant to this Agreement, (c) the nature of the election to be made by
the Participant under Section 83(b), and (d) the effect and requirements of the 83(b) Election under relevant state and local tax
laws.

 

     

     

    

 

10.               
Amendment. The Board may at any time or times amend the Plan or this Agreement for the purpose of satisfying the
requirements of any changes in applicable laws or regulations or for any other purpose which at the time may be permitted by law.
No termination, amendment of the Plan or amendment of this Agreement shall, without the Shareholder’s consent, materially
adversely affect the Shareholder’s rights under this Agreement.

 

11.               
Notices. All notices, requests, consents and other communications shall be in writing and be deemed given when delivered
personally, by telex or facsimile transmission or when received if mailed by first class registered or certified mail, postage
prepaid. Notices to the Company or the Shareholder shall be addressed as set forth underneath their signatures below, or to such
other address or addresses as may have been furnished by such party in writing to the other.

 

12.               
Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware
without regard to conflict of law principles.

 

13.

part at any time and for any reason; provided, however, that any amendment of the Plan which is necessary to comply with
any applicable tax or regulatory requirement, shall be subject to the approval of the Company’s stockholders. Stockholder
approval shall not be required for any other amendment of the Plan. No amendment, suspension or termination of the Plan shall materially
adversely affect the rights of a Participant, without such Participant’s consent, with respect to any Award previously made.
Unless terminated earlier by the Board, the Plan shall terminate on the tenth anniversary of the Plan’s date of adoption
by the Board. In no event shall any Awards be made under the Plan after such expiration date, but Awards previously granted may
extend beyond such date.

 

     

     

    

 

12.2.            
Amendment, Suspension, Termination of an Award. The Committee may modify, amend or terminate any outstanding Award,
including, without limitation, substituting therefor another Award of the same or a different type and changing the date of exercise
or realization; provided, however, that the Participant’s consent to such action shall be required unless the Committee
determines that the action, taking into account any related action, would not materially adversely affect the Participant.

The Committee will have the authority to adopt,
alter and repeal such administrative rules, guidelines and practices governing the Plan as it, from time to time, deems advisable;
to establish the terms and form of each Award Agreement; to interpret the terms and provisions of the Plan and any Award issued

any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award Agreement in the manner and to the extent
it deems necessary to carry out the intent of the Plan.

 

The Committee may delegate to one or more
officers of the Company the authority to grant Awards to Participants who are not subject to the requirements of Section 16
of the Exchange Act and the rules and regulations thereunder, provided that the Committee shall have fixed the total number
of Shares subject to such delegation. Any such delegation shall be subject to the applicable corporate laws of the State of Delaware.
The Committee may revoke any such allocation or delegation at any time for any reason with or without prior notice.

determination, act or omission in connection with the Plan or any Award.

 

Section 3.     Shares
Subject to the Plan.

 

(a)            Shares
Subject to the Plan. Subject to adjustment as provided in Section 3(c) of the Plan, the maximum number of
Shares that may be issued in respect of Awards under the Plan is 8,650,000 Shares (the “Plan Limit”). Subject
to adjustment as provided in Section 3(c) of the Plan, the maximum aggregate number of Shares that may be issued in respect
of Incentive Stock Options under the Plan is 8,650,000. Any shares issued hereunder may consist, in whole or in part, of authorized
and unissued shares or treasury shares. Any shares issued by the Company through the assumption or substitution of outstanding
grants in connection with the acquisition of another entity shall not reduce the maximum number of shares available for delivery
under the Plan.

 

(i)            If
any award granted under the Inhibikase Therapeutics, Inc. 2011 Equity Incentive Plan, as amended (the “2011 Plan”)
expires, terminates, is canceled or is forfeited for any reason after the Effective Date, the Shares subject to that award will
be added to the Plan Limit and become available for issuance hereunder.

 

(ii)            The
maximum total grant date fair value of Awards (as measured by the Company for financial accounting purposes) granted to any Participant
in his or her capacity as a Non-Employee Director in any single calendar year shall not exceed $250,000.

 

(b)            Effect
of the Expiration or Termination of Awards. If and to the extent that an Option or a Stock Appreciation Right expires, terminates
or is canceled or forfeited for any reason without having been exercised in full, the Shares associated with that Award will again
become available for grant under the Plan. Similarly, if and to the extent an Award of Restricted Stock or Restricted Stock Units
is canceled or forfeited for any reason, the Shares subject to that Award will again become available for grant under the Plan.
Shares withheld in settlement of a tax withholding obligation associated with an Award, or in satisfaction of the exercise price
payable upon exercise of an Option, will not again become available for grant under the Plan.

 

    	 	-5-	 

     

    

 

(c)            Other
Adjustment. In the event of any corporate event or transaction such as a merger, consolidation, reorganization, recapitalization,
stock split, reverse stock split, split up, spin-off, combination of shares, exchange of shares, stock dividend, dividend in kind,
or other like change in capital structure (other than ordinary cash dividends) to shareholders of the Company, or other similar
corporate event or transaction affecting the Shares, the Committee, to prevent dilution or enlargement of Participants’ rights
under the Plan, shall, in such manner as it deems equitable, substitute or adjust, in its sole discretion, the number and kind
of shares that may be issued under the Plan or under any outstanding Awards, the number and kind of shares subject to outstanding
Awards, the exercise price, grant price or purchase price applicable to outstanding Awards, and/or any other affected terms and
conditions of this Plan or outstanding Awards.

 

(d)            Change
in Control. Notwithstanding anything to the contrary set forth in the Plan, upon or in anticipation of any Change in Control,
the Committee may, in its sole and absolute discretion and without the need for the consent of any Participant, take one or more
of the following actions contingent upon the occurrence of that Change in Control:

 

(i)            cause
any or all outstanding Awards to become vested and immediately exercisable (as applicable), in whole or in part;

 

(ii)            cause
any outstanding Option or Stock Appreciation Right to become fully vested and immediately exercisable for a reasonable period in
advance of the Change in Control and, to the extent not exercised prior to that Change in Control, cancel that Option or Stock
Appreciation Right upon closing of the Change in Control;

 

(iii)          cancel
any unvested Award or unvested portion thereof, with or without consideration;

 

(iv)          cancel
any Award in exchange for a substitute award;

 

(v)          redeem
any Restricted Stock or Restricted Stock Unit for cash and/or other substitute consideration with value equal to the Fair Market
Value of an unrestricted Share on the date of the Change in Control;

 

(vi)          cancel
any Option or Stock Appreciation Right in exchange for cash and/or other substitute consideration with a value equal to: (A) the
number of Shares subject to that Option or Stock Appreciation Right, multiplied by (B) the difference, if any, between the
Fair Market Value per Share on the date of the Change in Control and the exercise price of that Option or the base price of the
Stock Appreciation Right; provided, that if the Fair Market Value per Share on the date of the Change in Control does not
exceed the exercise price of any such Option or the base price of any such Stock Appreciation Right, the Committee may cancel that
Option or Stock Appreciation Right without any payment of consideration therefor; and/or

 

    	 	-6-	 

     

    

 

(vii)            take
such other action as the Committee shall determine to be reasonable under the circumstances.

 

Notwithstanding any provision of this Section 3(d),
in the case of any Award subject to Section 409A of the Code, the Committee shall only be permitted to take actions under
this Section 3(d) to the extent that such actions would be consistent with the intended treatment of such Award under
Section 409A of the Code.

 

In the discretion of the Committee, any cash
or substitute consideration payable upon cancellation of an Award may be subjected to (i) vesting terms substantially identical
to those that applied to the cancelled Award immediately prior to the Change in Control, or (ii) earn-out, escrow, holdback
or similar arrangements, to the extent such arrangements are applicable to any consideration paid to stockholders in connection
with the Change in Control.

 

(e)            Foreign
Holders. Notwithstanding any provision of the Plan to the contrary, in order to comply
with the laws in countries other than the United States in which the Company and its Affiliates operate or have employees,
directors and consultants, or in order to comply with the requirements of any foreign securities
exchange or other Applicable Law, the Committee, in its sole discretion, shall have the power and authority to: (i) modify
the terms and conditions of any Award granted to employees, directors and consultants outside
the United States to comply with Applicable Law (including, without limitation, applicable foreign laws or listing requirements
of any foreign securities exchange); (ii) establish subplans and modify exercise procedures and other terms and procedures,
to the extent such actions may be necessary or advisable; provided, however, that no such subplans and/or
modifications shall increase the share limitations contained in Section 3(a); and (iii) take any action, before
or after an Award is made, that it deems advisable to obtain approval or comply with any necessary local governmental regulatory
exemptions or approvals or listing requirements of any foreign securities exchange.

 

Section 4.     Eligibility.
Employees, Directors, consultants, and other individuals who provide services to the Company or its Affiliates are eligible to
be granted Awards under the Plan; provided, however, that only employees of the Company, any Parent or a Subsidiary are
eligible to be granted Incentive Stock Options.

 

Section 5.     Options.
Options granted under the Plan may be of two types: (i) Incentive Stock Options or (ii) Non-Qualified Stock Options.
The Award Agreement shall state whether such grant is an Incentive Stock Option or a Non-Qualified Stock Option. Any Option granted
under the Plan will be in such form as the Committee may at the time of such grant approve.

 

The Award Agreement evidencing any Option
will incorporate the following terms and conditions and will contain such additional terms and conditions, not inconsistent with
the terms of the Plan, as the Committee deems appropriate in its sole and absolute discretion:

 

(a)            Option
Price. The exercise price per Share under an Option will be determined by the Committee and will not be less than 100% of the
Fair Market Value of a Share on the date of the grant. However, any Incentive Stock Option granted to any Participant who, at the
time the Option is granted, owns, either directly and/or within the meaning of the attribution rules contained in Section 424(d) of
the Code, stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, will have an
exercise price per Share of not less than 110% of Fair Market Value per Share on the date of the grant.

 

    	 	-7-	 

     

    

 

(b)            Option
Term. The term of each Option will be fixed by the Committee, but no Option will be exercisable more than 10 years after the
date the Option is granted. However, any Incentive Stock Option granted to any Participant who, at the time such Option is granted,
owns, either directly and/or within the meaning of the attribution rules contained in Section 424(d) of the Code,
stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, may not have a term of
more than 5 years. No Option may be exercised by any Person after expiration of the term of the Option.

 

(c)            Exercisability.
Options will vest and be exercisable at such time or times and subject to such terms and conditions as determined by the Committee.
Such terms and conditions may include the continued employment or service of the Participant, the attainment of specified individual
or corporate performance goals, or such other factors as the Committee may determine in its sole discretion (the “Vesting
Conditions”).

 

(d)            Method
of Exercise. Subject to the terms of the applicable Award Agreement, the exercisability provisions of Section 5(c) and
the termination provisions of Section 7, Options may be exercised in whole or in part from time to time during their
term by the delivery of written notice to the Company specifying the number of Shares to be purchased. Such notice will be accompanied
by payment in full of the purchase price, either by certified or bank check, or such other means as the Committee may accept. The
Committee may, in its sole discretion, permit payment of the exercise price of an Option in the form of previously acquired Shares
based on the Fair Market Value of the Shares on the date the Option is exercised or through means of a “net settlement,”
whereby the Option exercise price will not be due in cash and where the number of Shares issued upon such exercise will be equal
to: (A) the product of (i) the number of Shares as to which the Option is then being exercised, and (ii) the excess,
if any, of (a) the then current Fair Market Value per Share over (b) the Option exercise price, divided by (B) the
then current Fair Market Value per Share.

 

No Shares will be issued upon exercise of
an Option until full payment therefor has been made. A Participant will not have the right to distributions or dividends or any
other rights of a stockholder with respect to Shares subject to the Option until the Participant has given written notice of exercise,
has paid in full for such Shares, if requested, has given the representation described in Section 16(a) hereof
and fulfills such other conditions as may be set forth in the applicable Award Agreement.

 

(e)            Incentive
Stock Option Limitations. In the case of an Incentive Stock Option, the aggregate Fair Market Value (determined as of the time
of grant) of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Participant during
any calendar year under the Plan and/or any other plan of the Company, its Parent or any Subsidiary will not exceed $100,000. For
purposes of applying the foregoing limitation, Incentive Stock Options will be taken into account in the order granted. To
the extent any Option does not meet such limitation, that Option will be treated for all purposes as a Non-Qualified Stock Option.

 

    	 	-8-	 

     

    

 

(f)            Termination
of Service. Unless otherwise specified in the applicable Award Agreement or as otherwise provided by the Committee at or after
the time of grant, Options will be subject to the terms of Section 7 with respect to exercise upon or following termination
of employment or other service.

 

Section 6.     Stock
Appreciation Right. Subject to the other terms of the Plan, the Committee may grant
Stock Appreciation Rights to eligible individuals. Each Stock Appreciation Right shall represent the right to receive, upon exercise,
an amount equal to the number of Shares subject to the Award that is being exercised multiplied by the excess of (i) the Fair
Market Value of a Share on the date the Award is exercised, over (ii) the base price specified in the applicable Award Agreement.
Distributions may be made in cash, Shares, or a combination of both, at the discretion of the Committee. Each Stock Appreciation
Right shall be evidenced by an Award Agreement in a form that is approved by the Committee. Such Award Agreement shall indicate
the base price, the term and the Vesting Conditions for such Award. A Stock Appreciation Right base price may never be less than
the Fair Market Value of the underlying common stock of the Company on the date of grant of such Stock Appreciation Right. The
term of each Stock Appreciation Right will be fixed by the Committee, but no Stock Appreciation Right will be exercisable more
than 10 years after the date the Stock Appreciation Right is granted. Subject to the terms and conditions of the applicable Award
Agreement, Stock Appreciation Rights may be exercised in whole or in part from time to time during their term by the delivery of
written notice to the Company specifying the number of Shares to be exercised. Unless otherwise specified in the applicable Award
Agreement or as otherwise provided by the Committee at or after the time of grant, Stock Appreciation Rights will be subject to
the terms of Section 7 with respect to exercise upon or following termination of employment or other service.

 

Section 7.     Termination
of Service. Unless otherwise specified with respect to a particular Option or Stock
Appreciation Right in the applicable Award Agreement or otherwise determined by the Committee, any portion of an Option or Stock
Appreciation Right that is not exercisable upon termination of service will expire immediately and automatically upon such termination
and any portion of an Option or Stock Appreciation Right that is exercisable upon termination of service will expire on the date
it ceases to be exercisable in accordance with this Section 7.

 

(a)            Termination
by Reason of Death. If a Participant’s service with the Company or any Affiliate terminates by reason of death, any Option
or Stock Appreciation Right held by such Participant may thereafter be exercised, to the extent it was exercisable at the time
of his or her death or on such accelerated basis as the Committee may determine at or after grant, by the legal representative
of the estate or by the legatee of the Participant, for a period expiring (i) at such time as may be specified by the Committee
at or after grant, or (ii) if not specified by the Committee, then 12 months from the date of death, or (iii) if sooner
than the applicable period specified under (i) or (ii) above, upon the expiration of the stated term of such Option or
Stock Appreciation Right.

 

    	 	-9-	 

     

    

 

(b)            Termination
by Reason of Disability. If a Participant’s service with the Company or any Affiliate terminates by reason of Disability,
any Option or Stock Appreciation Right held by such Participant may thereafter be exercised by the Participant or his or her personal
representative, to the extent it was exercisable at the time of termination, or on such accelerated basis as the Committee may
determine at or after grant, for a period expiring (i) at such time as may be specified by the Committee at or after grant,
or (ii) if not specified by the Committee, then 12 months from the date of termination of service, or (iii) if sooner
than the applicable period specified under (i) or (ii) above, upon the expiration of the stated term of such Option or
Stock Appreciation Right.

  

(c)            Cause.
If a Participant’s service with the Company or any Affiliate is terminated for Cause or if a Participant resigns at a time
that there was a Cause basis for such Participant’s termination: (i) any Option or Stock Appreciation Right, or portion
thereof, not already exercised will be immediately and automatically forfeited as of the date of such termination, and (ii) any
Shares for which the Company has not yet delivered share certificates will be immediately and automatically forfeited and the Company
will refund to the Participant the Option exercise price paid for such Shares, if any.

 

(d)            Other
Termination. If a Participant’s service with the Company or any Affiliate terminates for any reason other than death,
Disability or Cause, any Option or Stock Appreciation Right held by such Participant may thereafter be exercised by the Participant,
to the extent it was exercisable at the time of such termination, or on such accelerated basis as the Committee may determine at
or after grant, for a period expiring (i) at such time as may be specified by the Committee at or after grant, or (ii) if
not specified by the Committee, then 90 days from the date of termination of service, or (iii) if sooner than the applicable
period specified under (i) or (ii) above, upon the expiration of the stated term of such Option or Stock Appreciation
Right.

 

Section 8.     Restricted
Stock.

 

(a)            Issuance.
Restricted Stock may be issued either alone or in conjunction with other Awards. The Committee will determine the time or times
within which Restricted Stock may be subject to forfeiture, and all other conditions of such Awards. The purchase price for Restricted
Stock may, but need not, be zero. The prospective recipient of an Award of Restricted Stock will not have any rights with respect
to such Award, unless and until such recipient has delivered to the Company an executed Award Agreement and has otherwise complied
with the applicable terms and conditions of such Award.

 

(b)            Certificates.
Upon the Award of Restricted Stock, the Committee may direct that a certificate or certificates representing the number of shares
of common stock subject to such Award be issued to the Participant or placed in a restricted stock account (including an electronic
account) with the transfer agent and in either case designating the Participant as the registered owner. The certificate(s), if
any, representing such shares shall be physically or electronically legended, as applicable, as to sale, transfer, assignment,
pledge or other encumbrances during the Restriction Period and if issued to the Participant, returned to the Company, to be held
in escrow during the Restriction Period. As a condition to any Award of Restricted Stock, the Participant may be required to deliver
to the Company a share power, endorsed in blank, relating to the Shares covered by such Award.

(c)            Restrictions
and Conditions. The Award Agreement evidencing the grant of any Restricted Stock will incorporate the following terms and conditions
and such additional terms and conditions, not inconsistent with the terms of the Plan, as the Committee deems appropriate in its
sole and absolute discretion:

 

(i)            During
a period commencing with the date of an Award of Restricted Stock and ending at such time or times as specified by the Committee
(the “Restriction Period”), the Participant will not be permitted to sell, transfer, pledge, assign or otherwise
encumber Restricted Stock awarded under the Plan. The Committee may condition the lapse of restrictions on Restricted Stock upon
one or more Vesting Conditions.

 

(ii)         While
any Share of Restricted Stock remains subject to restriction, the Participant will have, with respect to the Restricted Stock,
the right to vote the Shares. If any cash distributions or dividends are payable with respect to the Restricted Stock, the Committee,
in its sole discretion, may require the cash distributions or dividends to be subjected to the same Restriction Period as is applicable
to the Restricted Stock with respect to which such amounts are paid, or, if the Committee so determines, reinvested in additional
Restricted Stock to the extent Shares are available under Section 3(a) of the Plan. A Participant shall not be
entitled to interest with respect to any dividends or distributions subjected to the Restriction Period. Any distributions or dividends
paid in the form of securities with respect to Restricted Stock will be subject to the same terms and conditions as the Restricted
Stock with respect to which they were paid, including, without limitation, the same Restriction Period.

 

(iii)         Subject
to the provisions of the applicable Award Agreement or as otherwise determined by the Committee, if a Participant’s service
with the Company and its Affiliates terminates prior to the expiration of the applicable Restriction Period, the Participant’s
Restricted Stock that then remains subject to forfeiture will then be forfeited automatically.

 

Section 9.     Restricted
Stock Units. Subject to the other terms of the Plan, the Committee may grant Restricted
Stock Units to eligible individuals and may impose one or more Vesting Conditions on such units. Each Restricted Stock Unit shall
be evidenced by an Award Agreement in the form that is approved by the Committee and that is not inconsistent with the terms and
conditions of the Plan. Each Restricted Stock Unit will represent a right to receive from the Company, upon fulfillment of any
applicable conditions, an amount equal to the Fair Market Value (at the time of the distribution) of one Share. Distributions may
be made in Shares. All other terms governing Restricted Stock Units, such as Vesting Conditions, time and form of payment and termination
of units shall be set forth in the applicable Award Agreement. The Participant shall not have any shareholder rights with respect
to the Shares subject to a Restricted Stock Unit Award until that Award vests and the Shares are actually issued thereunder, provided,
however, that an Award Agreement may provide for the inclusion of dividend equivalent payments or unit credits with respect to
the Award in the discretion of the Committee. Subject to the provisions of the applicable Award Agreement or as otherwise determined
by the Committee, if a Participant’s service with the Company terminates prior to the Restricted Stock Unit Award vesting
in full, any portion of the Participant’s Restricted Stock Units that then remain subject to forfeiture will then be forfeited
automatically.

Section 10.     Amendments
and Termination. The Board may amend, alter or discontinue the Plan at any time. However,
except as otherwise provided in Section 3, no amendment, alteration or discontinuation will be made which would impair
the rights of a Participant with respect to an Award without that Participant’s consent or which, without the approval of
such amendment within 365 days of its adoption by the Board or by the Company’s stockholders in a manner consistent with
Treas. Reg. § 1.422-3 (or any successor provision), would: (i) increase the total number of Shares reserved for issuance
hereunder, or (ii) change the persons or class of persons eligible to receive Awards.

 

Section 11.     Prohibition
on Repricing Programs. Neither the Committee nor the Board shall (i) implement
any cancellation/re-grant program pursuant to which outstanding Options or Stock Appreciation Rights under the Plan are cancelled
and new Options or Stock Appreciation Rights are granted in replacement with a lower exercise or base price per share, (ii) cancel
outstanding Options or Stock Appreciation Rights under the Plan with exercise prices or base prices per share in excess of the
then current Fair Market Value per Share for consideration payable in equity securities of the Company or (iii) otherwise
directly reduce the exercise price or base price in effect for outstanding Options or Stock Appreciation Rights under the Plan,
without in each such instance obtaining shareholder approval.

 

Section 12.     Conditions
Upon Grant of Awards and Issuance of Shares.

 

(a)            The
implementation of the Plan, the grant of any Award and the issuance of Shares in connection with the issuance, exercise or vesting
of any Award made under the Plan shall be subject to the Company’s procurement of all approvals and permits required by regulatory
authorities having jurisdiction over the Plan, the Awards made under the Plan and the Shares issuable pursuant to those Awards.

 

(b)            No
Shares or other assets shall be issued or delivered under the Plan unless and until there shall have been compliance with all applicable
requirements of Applicable Law, including the filing and effectiveness of the Form S-8 registration statement for the Shares
issuable under the Plan, and all applicable listing requirements of any stock exchange on which Shares are then listed for trading.

 

Section 13.     Limits
on Transferability; Beneficiaries. No Award or other right or interest of a Participant
under the Plan shall be pledged, encumbered, or hypothecated to, or in favor of, or subject to any lien, obligation, or liability
of such Participant to, any party, other than the Company, any Subsidiary or Affiliate, or assigned or transferred by such Participant
other than by will or the laws of descent and distribution, and such Awards and rights shall be exercisable during the lifetime
of the Participant only by the Participant or his or her guardian or legal representative. Notwithstanding the foregoing, the Committee
may, in its discretion, provide that Awards or other rights or interests of a Participant granted pursuant to the Plan (other than
an Incentive Stock Option) be transferable, without consideration, to immediate family members (i.e., children, grandchildren or
spouse), to trusts for the benefit of such immediate family members and to partnerships in which such family members are the only
partners. The Committee may attach to such transferability feature such terms and conditions as it deems advisable. In addition,
a Participant may, in the manner established by the Committee, designate a beneficiary (which may be a person or a trust) to exercise
the rights of the Participant, and to receive any distribution, with respect to any Award upon the death of the Participant. A
beneficiary, guardian, legal representative or other person claiming any rights under the Plan from or through any Participant
shall be subject to all terms and conditions of the Plan and any Award Agreement applicable to such Participant, except as otherwise
determined by the Committee, and to any additional restrictions deemed necessary or appropriate by the Committee.

Section 14.     Withholding.
No later than the date as of which an amount first becomes includible in the gross income of the Participant for federal income
tax purposes with respect to any Award under the Plan, the Participant will pay to the Company, or make arrangements satisfactory
to the Company regarding the payment of, any federal, state or local taxes of any kind required by law to be withheld with respect
to such amount. To the extent authorized by the Committee, the required tax withholding may be satisfied by the withholding of
Shares subject to the Award based on the Fair Market Value on the date of withholding, but in any case not in excess of the amount
determined based on the maximum statutory tax rate in the applicable jurisdiction. The obligations of the Company under the Plan
will be conditioned on such payment or arrangements and the Company will have the right to deduct any such taxes from any payment
of any kind otherwise due to the Participant.

 

Section 15.     Liability
of Company.

 

(a)            Inability
to Obtain Authority. If the Company cannot, by the exercise of commercially reasonable efforts, obtain authority from any regulatory
body having jurisdiction for the sale of any Shares under this Plan, and such authority is deemed by the Company’s counsel
to be necessary to the lawful issuance of those Shares, the Company will be relieved of any liability for failing to issue or sell
those Shares.

 

(b)            Rights
of Participants and Beneficiaries. The Company will pay all amounts payable under this Plan only to the applicable Participant,
or beneficiaries entitled thereto pursuant to this Plan. The Company will not be liable for the debts, contracts, or engagements
of any Participant or his or her beneficiaries, and rights to cash payments under this Plan may not be taken in execution by attachment
or garnishment, or by any other legal or equitable proceeding while in the hands of the Company.

 

Section 16.     General
Provisions.

 

(a)            The
Board may require each Participant to represent to and agree with the Company in writing that the Participant is acquiring securities
of the Company for investment purposes and without a view to distribution thereof and as to such other matters as the Board believes
are appropriate.

 

    	 	-13-	 

     

    

 

(b)            The
Awards shall be subject to the Company’s stock ownership policies, as in effect from time to time.

 

(c)            All
certificates for Shares or other securities delivered under the Plan will be subject to such share-transfer orders and other restrictions
as the Board may deem advisable under the rules, regulations and other requirements of the Securities Act of 1933, as amended,
the Exchange Act, any stock exchange upon which the Shares are then listed, and any other Applicable Law, and the Board may cause
a legend or legends to be put on any such certificates to make appropriate reference to such restrictions.

 

(d)            Nothing
contained in the Plan will prevent the Board from adopting other or additional compensation arrangements, subject to stockholder
approval if such approval is required.

 

(e)            Neither
the adoption of the Plan nor the execution of any document in connection with the Plan will: (i) confer upon any employee
or other service provider of the Company or an Affiliate any right to continued employment or engagement with the Company or such
Affiliate, or (ii) interfere in any way with the right of the Company or such Affiliate to terminate the employment or engagement
of any of its employees or other service providers at any time.

 

(f)            The
Awards (whether vested or unvested) shall be subject to rescission, cancellation or recoupment, in whole or in part, under any
current or future “clawback” or similar policy of the Company that is applicable to the Participant. Notwithstanding
any other provisions in this Plan, any Award which is subject to recovery under any law, government regulation or stock exchange
listing requirement, will be subject to such deductions and clawback as may be required to be made pursuant to such law, government
regulation or stock exchange listing requirement.

 

Section 17.     Effective
Date of Plan. The Plan will become effective upon the execution of an underwriting
agreement with respect to the Company’s initial public offering of common stock (the date upon which the execution of such
agreement occurs, the “Effective Date”).

 

Section 18.     Term
of Plan. Unless the Plan shall theretofore have been terminated in accordance with
Section 10, the Plan shall terminate on the 10-year anniversary of the effective date, and no Awards under the Plan
shall thereafter be granted.

 

Section 19.     Invalid
Provisions. In the event that any provision of this Plan is found to be invalid or
otherwise unenforceable under any Applicable Law, such invalidity or unenforceability will not be construed as rendering any other
provisions contained herein as invalid or unenforceable, and all such other provisions will be given full force and effect to the
same extent as though the invalid or unenforceable provision was not contained herein.

 

Section 20.     Governing
Law. The Plan and all Awards granted hereunder will be governed by and construed in
accordance with the laws and judicial decisions of the State of Delaware, without regard to the application of the principles of
conflicts of laws.

 

    	 	-14-	 

     

    

 

Section 21.     Notices.
Any notice to be given to the Company pursuant to the provisions of this Plan must be given in writing and addressed, if to the
Company, to its principal executive office to the attention of its Chief Financial Officer (or such other Person as the Company
may designate in writing from time to time), and, if to a Participant, to the address contained in the Company’s personnel
files, or at such other address as that Participant may hereafter designate in writing to the Company. Any such notice will be
deemed duly given: if delivered personally or via recognized overnight delivery service, on the date and at the time so delivered;
if sent via telecopier or email, on the date and at the time telecopied or emailed with confirmation of delivery; or, if mailed,
five (5) days after the date of mailing by registered or certified mail.
