COGNITION THERAPEUTICS, INC.


 


AMENDED AND RESTATED

2007 EQUITY INCENTIVE PLAN


 


The purpose of the Cognition Therapeutics, Inc.
Amended and Restated 2007 Equity Incentive Plan (this “Plan”) is to provide (i) designated employees of Cognition Therapeutics, Inc.
(the “Company”) and its parents and subsidiaries, (ii) certain consultants and advisors who perform services for the
Company or its parents or subsidiaries and (iii) non-employee members of the Board of Directors of the Company (the “Board”)
with the opportunity to receive grants of incentive stock options, nonqualified stock options and stock awards. The Company believes that
the Plan will encourage the participants to contribute materially to the growth of the Company, thereby benefitting the Company’s
stockholders, and will align the economic interests of the participants with those of the stockholders.


 


1.            Administration.


 


(a)            Committee.
This Plan shall be administered and interpreted by the Board or by a committee consisting of
members of the Board, which shall be appointed by the Board. After an initial public offering of the Company’s stock as described
in Section 17(b) (a “Public Offering”), this Plan shall be administered by a committee of Board members, which may
consist of “outside directors” as defined under section 162(m) of the Internal Revenue Code of 1986, as amended (the
 “Code”), and related Treasury regulations, and “non-employee directors” as defined under Rule 16b-3 under
the Securities Exchange Act of 1934, as amended (the “Exchange Act”). However, the Board may ratify or approve any grants
as it deems appropriate, and the Board shall approve and administer all grants made to non-employee directors. The committee may delegate
authority to one or more subcommittees as it deems appropriate. To the extent that a committee or subcommittee administers this Plan,
references in this Plan to the “Board” shall be deemed to refer to the committee or subcommittee.


 


(b)            Board
Authority. The Board shall have the sole authority to (i) determine the individuals
to whom grants shall be made under this Plan, (ii) determine the type, size and terms of the grants to be made to each such individual,
(iii) determine the time when the grants will be made and the duration of any applicable exercise or restriction period, including
the criteria for exercisability and the acceleration of exercisability, (iv) amend the terms of any previously issued grant, and
(v) deal with any other matters arising under this Plan.


 






     


     


    

 


(c)            Board
Determinations. The Board shall have full power and authority to administer and interpret
this Plan, to make factual determinations and to adopt or amend such rules, regulations, agreements and instruments for implementing this
Plan and for the conduct of its business as it deems necessary or advisable, in its sole discretion. The Board’s interpretations
of this Plan and all determinations made by the Board pursuant to the powers vested in it hereunder shall be conclusive and binding on
all persons having any interest in this Plan or in any awards granted hereunder. All powers of the Board shall be executed in its sole
discretion, in the best interest of the Company, not as a fiduciary, and in keeping with the objectives of this Plan and need not be uniform
as to similarly situated individuals.


 


2.            Grants.
Awards under this Plan may consist of grants of incentive stock options as described in Section 5
(“Incentive Stock Options”), nonqualified stock options as described in Section 5 (“Nonqualified Stock Options”)
(Incentive Stock Options and Nonqualified Stock Options are collectively referred to as “Options”) and stock awards as described
in Section 6 (“Stock Awards”) (hereinafter collectively referred to as “Grants”). All Grants shall be subject
to the terms and conditions set forth herein and to such other terms and conditions consistent with this Plan as the Board deems appropriate
and as are specified in writing by the Board to the individual in a grant instrument or an amendment to the grant instrument (the “Grant
Instrument”). All Grants shall be made conditional upon the Grantee’s acknowledgement, in writing or by acceptance of the
Grant, that all decisions and determinations of the Board shall be final and binding on the Grantee, his or her beneficiaries and any
other person having or claiming an interest under such Grant. The Board shall approve the form and provisions of each Grant Instrument.
Grants under a particular Section of this Plan need not be uniform as among the grantees.


 


3.            Shares
Subject to This Plan.


 


(a)            Shares
Authorized. Subject to adjustment as described below, the aggregate number of shares of common
stock of the Company (“Company Stock”) that may be issued under this Plan is 11,189,392 shares, all of which may be issued
as incentive stock options. After a Public Offering, the maximum aggregate number of shares of Company Stock that shall be subject to
Grants made under this Plan to any individual during any calendar year shall be 3,900,000 shares, subject to adjustment as described below.
Shares issued under this Plan may be authorized but unissued shares of Company Stock or reacquired shares of Company Stock, including
shares purchased by the Company on the open market for purposes of this Plan. If and to the extent Options granted under this Plan terminate,
expire, or are canceled, forfeited, exchanged or surrendered without having been exercised or if any Stock Awards (including restricted
Stock Awards received upon the exercise of Options) are forfeited, the shares subject to such Grants shall again be available for purposes
of this Plan.


 


(b)            Adjustments.
If there is any change in the number or kind of shares of Company Stock
outstanding (i) by reason of a stock dividend, spinoff, recapitalization, stock split, or combination or exchange of shares, (ii) by
reason of a merger, reorganization or consolidation, (iii) by reason of a reclassification or
change in par value, or (iv) by reason of any other extraordinary or unusual event affecting the outstanding Company Stock as a class
without the Company’s receipt of consideration, or if the value of outstanding shares of Company Stock is substantially reduced
as a result of a spinoff or the Company’s payment of an extraordinary


 






    	 	2	 



     


    

 


dividend or distribution, the maximum number of shares of
Company Stock available for Grants, the maximum number of shares of Company Stock that any individual participating in this Plan may be
granted in any year, the number of shares covered by outstanding Grants, the kind of shares issued under this Plan, and the price per
share of such Grants may be appropriately adjusted by the Board to reflect any increase or decrease in the number of, or change in the
kind or value of, issued shares of Company Stock to preclude, to the extent practicable, the enlargement or dilution of rights and benefits
under such Grants; provided, however, that any fractional shares resulting from such adjustment shall be eliminated. Any adjustments determined
by the Board shall be final, binding and conclusive.


 


4.            Eligibility
for Participation.


 


(a)            Eligible
Persons. All employees of the Company and its parents or subsidiaries (“Employees”),
including Employees who are officers or members of the Board, and members of the Board who are not Employees (“Non-Employee Directors”)
shall be eligible to participate in this Plan. Consultants and advisors who perform services for the Company or any of its parents or
subsidiaries (“Key Advisors”) shall be eligible to participate in this Plan if the Key Advisors render bona fide services
to the Company or its parents or subsidiaries, the services are not in connection with the offer and sale of securities in a capital-raising
transaction, and the Key Advisors do not directly or indirectly promote or maintain a market for the Company’s securities.


 


(b)            Selection
of Grantees. The Board shall select the Employees, Non-Employee Directors and Key Advisors
to receive Grants and shall determine the number of shares of Company Stock subject to a particular Grant in such manner as the Board
determines. Employees, Key Advisors and Non-Employee Directors who receive Grants under this Plan shall hereinafter be referred to as
 “Grantees.”


 


5.            Granting
of Options.


 


(a)            Number
of Shares. The Board shall determine the number of shares of Company Stock that will be subject
to each Grant of Options to Employees, Non-Employee Directors and Key Advisors.


 


(b)            Type
of Option and Price.


 


(i)            The
Board may grant Incentive Stock Options that are intended to qualify as “incentive stock options” within the meaning of section
422 of the Code or Nonqualified Stock Options that are not intended so to qualify or any combination of Incentive Stock Options and Nonqualified
Stock Options, all in accordance with the terms and conditions set forth herein. Incentive Stock Options may be granted only to employees
of the Company or its parents or subsidiaries, as defined in Section 424 of the Code. Nonqualified Stock Options may be granted to
Employees, Non-Employee Directors and Key Advisors.


 


(ii)            The
purchase price (the “Exercise Price”) of Company Stock subject to an Option shall be determined by the Board and may be equal
to or greater than the Fair Market Value (as defined below) of a share of Company Stock on the date the Option is granted; provided,
however, that (x) the Exercise Price of an Incentive Stock Option shall be equal to, or


 






    	 	3	 



     


    

 


greater than, the Fair Market Value of a share of Company Stock on
the date the Incentive Stock Option is granted and (y) an Incentive Stock Option may not be granted to an Employee who, at the time
of grant, owns stock possessing more than ten percent of the total combined voting power of all classes of stock of the Company or any
parent or subsidiary of the Company, unless the Exercise Price per share is not less than 110% of the Fair Market Value of Company Stock
on the date of grant.


 


(iii)            If
the Company Stock is publicly traded, then the Fair Market Value per share shall be determined as follows: (x) if the principal trading
market for the Company Stock is a national securities exchange or the Nasdaq National Market, the last reported sale price thereof on
the relevant date or (if there were no trades on that date) the latest preceding date upon which a sale was reported, or (y) if the
Company Stock is not principally traded on such exchange or market, the mean between the last reported “bid” and “asked”
prices of Company Stock on the relevant date, as reported on Nasdaq or, if not so reported, as reported by the National Daily Quotation
Bureau, Inc. or as reported in a customary financial reporting service, as applicable and as the Board determines. If the Company
Stock is not publicly traded or, if publicly traded, is not subject to reported transactions or “bid” or “asked”
quotations as set forth above, the Fair Market Value per share shall be as determined by the Board.


 


(c)            Option
Term. The Board shall determine the term of each Option. The term of any Option shall not
exceed ten years from the date of grant. However, an Incentive Stock Option that is granted to an Employee who, at the time of grant,
owns stock possessing more than 10% of the total combined voting power of all classes of stock of the Company, or any parent or subsidiary
of the Company, may not have a term that exceeds five years from the date of grant.


 


(d)            Exercisability
of Options.


 


(i)            Options
shall become exercisable in accordance with such terms and conditions, consistent with this Plan, as may be determined by the Board and
specified in the Grant Instrument. The Board may accelerate the exercisability of any or all outstanding Options at any time for any reason.


 


(ii)            The
Board may provide in a Grant Instrument that the Grantee may elect to exercise part or all of an Option before it otherwise has become
exercisable. Any shares so purchased shall be restricted shares and shall be subject to a repurchase right in favor of the Company during
a specified restriction period, with the repurchase price equal to the lesser of (i) the Exercise Price or (ii) the Fair Market
Value of such shares at the time of repurchase, or such other restrictions as the Board deems appropriate.


 


(e)            Grants
to Non-Exempt Employees. Notwithstanding the foregoing, Options granted to persons who are
non-exempt employees under the Fair Labor Standards Act of 1938, as amended, shall have an Exercise Price not less than the Fair Market
Value of the Company Stock on the date of grant, and may not be exercisable for at least six months after the date of grant (except that
such Options may become exercisable, as determined by the Board, upon the Grantee’s death, Disability or retirement, or upon a Change
of Control or other circumstances permitted by applicable regulations).


 






    	 	4	 



     


    

 


(f)            Termination
of Employment, Disability or Death.


 


(i)            Except
as provided below, an Option may only be exercised while the Grantee is employed by, or providing service to, the Employer (as defined
below) as an Employee, Key Advisor or member of the Board. In the event that a Grantee ceases to be employed by, or provide service to,
the Employer for any reason other than Disability, death, or termination for Cause, any Option which is otherwise exercisable by the Grantee
shall terminate unless exercised within 90 days after the date on which the Grantee ceases to be employed by, or provide service to, the
Employer (or within such other period of time as may be specified by the Board), but in any event no later than the date of expiration
of the Option term. Except as otherwise provided by the Board, any of the Grantee’s Options that are not otherwise exercisable as
of the date on which the Grantee ceases to be employed by, or provide service to, the Employer shall terminate as of such date.


 


(ii)            In
the event the Grantee ceases to be employed by, or provide service to, the Employer on account of a termination for Cause by the Employer,
any Option held by the Grantee shall terminate as of the date the Grantee ceases to be employed by, or provide service to, the Employer.
In addition, notwithstanding any other provisions of this Section 5, if the Board determines that the Grantee has engaged in conduct
that constitutes Cause at any time while the Grantee is employed by, or providing service to, the Employer or after the Grantee’s
termination of employment or service, any Option held by the Grantee shall immediately terminate, and the Grantee shall automatically
forfeit all shares underlying any exercised portion of an Option for which the Company has not yet delivered the share certificates, upon
refund by the Company of the Exercise Price paid by the Grantee for such shares. Upon any exercise of an Option, the Company may withhold
delivery of share certificates pending resolution of an inquiry that could lead to a finding resulting in a forfeiture.


 


(iii)            In
the event the Grantee ceases to be employed by, or provide service to, the Employer because the Grantee is Disabled, any Option which
is otherwise exercisable by the Grantee shall terminate unless exercised within one year after the date on which the Grantee ceases to
be employed by, or provide service to, the Employer (or within such other period of time as may be specified by the Board), but in any
event no later than the date of expiration of the Option term. Except as otherwise provided by the Board, any of the Grantee’s Options
which are not otherwise exercisable as of the date on which the Grantee ceases to be employed by, or provide service to, the Employer
shall terminate as of such date.


 


(iv)            If
the Grantee dies while employed by, or providing service to, the Employer or within 90 days after the date on which the Grantee ceases
to be employed or provide service on account of a termination specified in Section 5(f)(i) above (or within such other period
of time as may be specified by the Board), any Option that is otherwise exercisable by the Grantee shall terminate unless exercised within
one year after the date on which the Grantee ceases to be employed by, or provide service to, the Employer (or within such other period
of time as may be specified by the Board), but in any event no later than the date of expiration of the Option term. Except as otherwise
provided by the Board, any of the Grantee’s Options that are not otherwise exercisable as of the date on which the Grantee ceases
to be employed by, or provide service to, the Employer shall terminate as of such date.


 






    	 	5	 



     


    

 


(v)            For
purposes of this Section 5(f) and Section 6:


 


(A)            The
term “Employer” shall include the Company and its parent and subsidiary corporations or other entities, as appropriate and
as determined by the Board.


 


(B)            “Employed
by, or provide service to, the Employer” shall mean employment or service as an Employee, Key Advisor or member of the Board (so
that, for purposes of exercising Options and satisfying conditions with respect to Stock Awards, a Grantee shall not be considered to
have terminated employment or service until the Grantee ceases to be an Employee, Key Advisor or member of the Board), unless the Board
determines otherwise.


 


(C)            “Disability”
shall mean a Grantee’s becoming disabled within the meaning of section 22(e)(3) of the Code, within the meaning of the Employer’s
long-term disability plan applicable to the Grantee, or as otherwise determined by the Board.


 


(D)            “Cause”
shall mean, except to the extent specified otherwise by the Board, a finding by the Board that the Grantee (i) has breached his or
her employment or service contract with the Employer, (ii) has engaged in disloyalty to the Company, including, without limitation,
fraud, embezzlement, theft, commission of a felony or proven dishonesty, (iii) has disclosed trade secrets or confidential information
of the Employer to persons not entitled to receive such information, (iv) has breached any written noncompetition or nonsolicitation
agreement between the Grantee and the Employer or (v) has engaged in such other behavior detrimental to the interests of the Employer
as the Board determines.


 


(g)            Exercise
of Options. A Grantee may exercise an Option that has become exercisable, in whole or in
part, by delivering a notice of exercise to the Company with payment of the Exercise Price. The Grantee shall pay the Exercise Price for
an Option as specified by the Board (w) in cash, (x) with the approval of the Board, by delivering shares of Company Stock owned
by the Grantee (including Company Stock acquired in connection with the exercise of an Option, subject to such restrictions as the Board
deems appropriate) and having a Fair Market Value on the date of exercise equal to the Exercise Price or by attestation (on a form prescribed
by the Board) to ownership of shares of Company Stock having a Fair Market Value on the date of exercise equal to the Exercise Price,
(y) after a Public Offering, payment through a broker in accordance with procedures permitted by Regulation T of the Federal Reserve
Board, or (z) by such other method as the Board may approve. The Board may authorize loans by the Company to Grantees in connection
with the exercise of an Option, upon such terms and conditions as the Board, in its sole discretion, deems appropriate. Shares of Company
Stock used to exercise an Option shall have been held by the Grantee for the requisite period of time to avoid adverse accounting consequences
to the Company with respect to the Option. The Grantee shall pay the Exercise Price and the amount of any withholding tax due (pursuant
to Section 7) at the time of exercise.


 


(h)            Limits
on Incentive Stock Options. Each Incentive Stock Option shall provide that, if the aggregate
Fair Market Value of the stock on the date of the grant with respect to which Incentive Stock Options are exercisable for the first time
by a Grantee during any calendar


 






    	 	6	 



     


    

 


year, under this Plan or any other stock option plan of the Company or a parent or subsidiary, exceeds
$100,000, then the Option, as to the excess, shall be treated as a Nonqualified Stock Option. An Incentive Stock Option shall not be granted
to any person who is not an Employee of the Company or a parent or subsidiary (within the meaning of section 424(f) of the Code)
of the Company.


 


6.            Stock
Awards. The Board may issue shares of Company Stock to an Employee, Non-Employee Director
or Key Advisor under a Stock Award, upon such terms as the Board deems appropriate. The following provisions are applicable to Stock Awards:


 


(a)            General
Requirements. Shares of Company Stock issued pursuant to Stock Awards may be issued for consideration
or for no consideration, and subject to restrictions or no restrictions, as determined by the Board. The Board may establish conditions
under which restrictions on Stock Awards shall lapse over a period of time or according to such other criteria as the Board deems appropriate.
The period of time during which the Stock Award will remain subject to restrictions will be designated in the Grant Instrument as the
 “Restriction Period.”


 


(b)            Number
of Shares. The Board shall determine the number of shares of Company Stock to be issued pursuant
to a Stock Award and the restrictions applicable to such shares.


 


(c)            Requirement
of Employment or Service. If the Grantee ceases to be employed by, or provide service to,
the Employer (as defined in Section 5(f)) during a period designated in the Grant Instrument as the Restriction Period, or if other
specified conditions are not met, the Stock Award shall terminate as to all shares covered by the award as to which the restrictions have
not lapsed, and those shares of Company Stock must be immediately returned to the Company. The Board may, however, provide for complete
or partial exceptions to this requirement as it deems appropriate.


 


(d)            Restrictions
on Transfer and Legend on Stock Certificate. During the Restriction Period, a Grantee may
not sell, assign, transfer, pledge or otherwise dispose of the shares of the Stock Award except to a successor under Section 8(a).
Each certificate for Stock Awards shall contain a legend giving appropriate notice of the restrictions in the Grant. The Grantee shall
be entitled to have the legend removed from the stock certificate covering the shares subject to restrictions when all restrictions on
such shares have lapsed. The Board may determine that the Company will not issue certificates for Stock Awards until all restrictions
on such shares have lapsed, or that the Company will retain possession of certificates for Stock Awards until all restrictions on such
shares have lapsed.


 


(e)            Right
to Vote and to Receive Dividends. During the Restriction Period, the Grantee shall have the
right to vote shares subject to Stock Awards and to receive any dividends or other distributions paid on such shares, subject to any restrictions
deemed appropriate by the Board.


 


(f)            Lapse
of Restrictions. All restrictions imposed on Stock Awards shall lapse upon the expiration
of the applicable Restriction Period and the satisfaction of all conditions imposed by the Board. The Board may determine, as to any or
all Stock Awards, that the restrictions shall lapse without regard to any Restriction Period.


 






    	 	7	 



     


    

 


7.            Withholding
of Taxes.


 


(a)            Required
Withholding. All Grants under this Plan shall be subject to applicable federal (including
FICA), state and local tax withholding requirements. The Employer may require that the Grantee or other person receiving or exercising
Grants pay to the Employer the amount of any federal, state or local taxes that the Employer is required to withhold with respect to such
Grants, or the Employer may deduct from other wages paid by the Employer the amount of any withholding taxes due with respect to such
Grants.


 


(b)            Election
to Withhold Shares. If the Board so permits, a Grantee may elect to satisfy the Employer’s
income tax withholding obligation with respect to a Grant by having shares withheld up to an amount that does not exceed the Grantee’s
minimum applicable withholding tax rate for federal (including FICA), state and local tax liabilities. The election must be in a form
and manner prescribed by the Board and may be subject to the prior approval of the Board.


 


8.            Transferability
of Grants.


 


(a)            Nontransferability
of Grants. Except as provided below, only the Grantee may exercise rights under a Grant during
the Grantee’s lifetime. A Grantee may not transfer those rights except (i) by will or by the laws of descent and distribution
or (ii) with respect to Grants other than Incentive Stock Options, if permitted in any specific case by the Board, pursuant to a
domestic relations order or otherwise as permitted by the Board. When a Grantee dies, the personal representative or other person entitled
to succeed to the rights of the Grantee may exercise such rights. Any such successor must furnish proof satisfactory to the Company of
his or her right to receive the Grant under the Grantee’s will or under the applicable laws of descent and distribution.


 


(b)            Transfer
of Nonqualified Stock Options. Notwithstanding the foregoing, the Board may provide, in a
Grant Instrument, that a Grantee may transfer Nonqualified Stock Options to family members, or one or more trusts or other entities for
the benefit of or owned by family members, consistent with applicable securities laws, according to such terms as the Board may determine;
provided that the Grantee receives no consideration for the transfer of an Option and the transferred Option shall continue to be subject
to the same terms and conditions as were applicable to the Option immediately before the transfer.


 


9.            Right
of First Refusal; Repurchase Right.


 


(a)            Offer.
Prior to a Public Offering, if at any time an individual desires to sell, encumber, or otherwise
dispose of shares of Company Stock that were distributed to him or her under this Plan and that are transferable, the individual may do
so only pursuant to a bona fide written offer, and the individual shall first offer the shares to the Company by giving the Company written
notice disclosing: (i) the name of the proposed transferee of the Company Stock; (ii) the certificate number and number of shares
of Company Stock proposed to be transferred or encumbered; (iii) the proposed price; (iv) all other terms of the proposed transfer;
and (v) a written copy of the proposed offer. Within 60 days after receipt of such notice, the Company shall have the option to purchase
all or part of such Company Stock at the price and on


 






    	 	8	 



     


    

 


the terms described in the written notice; provided that the Company may pay such
price in installments over a period not to exceed four years, at the discretion of the Board.


 


(b)            Sale.
In the event the Company (or a stockholder, as described below) does not exercise the option
to purchase Company Stock, as provided above, the individual shall have the right to sell, encumber, or otherwise dispose of the shares
of Company Stock described in subsection (a) at the price and on the terms of the transfer set forth in the written notice to the
Company, provided such transfer is effected within 15 days after the expiration of the option period. If the transfer is not effected
within such period, the Company must again be given an option to purchase, as provided above.


 


(c)            Assignment
of Rights. The Board, in its sole discretion, may waive the Company’s right of first
refusal and repurchase right under this Section 9. If the Company’s right of first refusal or repurchase right is so waived,
the Board may, in its sole discretion, assign such right to the remaining stockholders of the Company in the same proportion that each
stockholder’s stock ownership bears to the stock ownership of all the stockholders of the Company, as determined by the Board. To
the extent that a stockholder has been given such right and does not purchase his or her allotment, the other stockholders shall have
the right to purchase such allotment on the same basis.


 


(d)            Purchase
by the Company. Prior to a Public Offering, if a Grantee ceases to be employed by, or provide
service to, the Employer, the Company shall have the right to purchase all or part of any Company Stock distributed to him or her under
this Plan at its then current Fair Market Value (as defined in Section 5(b)) (or at such other price as may be established in the
Grant Instrument); provided, however, that such repurchase shall be made in accordance with applicable accounting rules to avoid
adverse accounting treatment.


 


(e)            Public
Offering. On and after a Public Offering, the Company shall have no further right to purchase
shares of Company Stock under this Section 9.


 


(f)            Stockholders
Agreement. Notwithstanding the provisions of this Section 9, if the Board requires that
a Grantee execute a Stockholders Agreement (or other agreement containing first refusal or repurchase rights) with respect to any Company
Stock distributed pursuant to this Plan, such Grantee shall execute such Stockholders Agreement (or other such agreement) as a condition
to retaining his or her rights to such Company Stock. If such Stockholders Agreement (or other such agreement) contains a right of first
refusal or repurchase right, the provisions of this Section 9 shall not apply to such Company Stock for as long as those provisions
of the Stockholders Agreement (or other agreement) are in effect, unless the Board determines otherwise.


 


10.            Change
of Control of the Company.


 


(a)            Definitions.


 


As used in this Plan, a “Change of Control”
shall mean:


 


(i)            any
merger or consolidation in which voting securities of the Company possessing more than 50% of the total combined voting power of the Company’s
outstanding


 






    	 	9	 



     


    

 


securities are Transferred to a person or persons different from the person holding those securities immediately prior to
such transaction and the composition of the Board following such transaction is such that the directors of the Company prior to the transaction
constitute less than 50% of the Board membership following the transaction;


 


(ii)            any
acquisition, directly or indirectly, by a person or related group of persons (other than the Company or a person that directly or indirectly
controls, is controlled by, or is under common control with, the Company) of beneficial ownership of voting securities of the Company
possessing more than 50% of the total combined voting power of the Company’s outstanding securities; provided, however, that, no
Change of Control shall be deemed to occur by reason of the acquisition of shares of the Company’s capital stock by an investor
in the Company in a capital-raising transaction;


 


(iii)            any
acquisition, directly or indirectly, by a person or related group of persons of the right to appoint a majority of the directors of the
Company or otherwise directly or indirectly control the management, affairs and business of the Company;


 


(iv)            any
sale transfer or other disposition of all or substantially all of the assets of the Company; or


 


(v)            a
complete liquidation or dissolution of the Company.


 


As used in this Section 10, “Transfer”
shall include any sale, exchange, assignment, gift, bequest, disposition, mortgage, charge, pledge, encumbrance, grant of a security interest
or other arrangement by which possession, legal title or beneficial ownership passes from one Person to another, or to the same Person
in a different capacity, whether or not voluntarily and whether or not for value, and including without limitation any merger or amalgamation
and any agreement to effect any of the foregoing.


 


(b)            Assumption
of Grants. Upon a Change of Control where the Company is not the surviving corporation (or
survives only as a subsidiary of another corporation), unless the Board determines otherwise, all outstanding Options that are not exercised
shall be assumed by, or replaced with comparable options by the surviving corporation (or a parent or subsidiary of the surviving corporation),
and outstanding Stock Awards shall be converted to Stock Awards of the surviving corporation (or a parent or subsidiary of the surviving
corporation).


 


(c)            Other
Alternatives. Notwithstanding the foregoing, in the event of a Change of Control, the Board
may take any of the following actions with respect to any or all outstanding Grants: the Board may (i) determine that outstanding
Options shall accelerate and become exercisable, in whole or in part, upon the Change of Control or upon such other event as the Board
determines, (ii) determine that the restrictions and conditions on outstanding Stock Awards shall lapse, in whole or in part, upon
the Change of Control or upon such other event as the Board determines, (iii) require that Grantees surrender their outstanding Options
in exchange for a payment by the Company, in cash or stock as determined by the Board, in an amount equal to the amount by which the then
Fair Market Value of the shares of Company Stock subject to the Grantee’s unexercised Options exceeds the Exercise Price of the
Options or (iv) after giving Grantees an opportunity to exercise their outstanding Options, terminate any or all unexercised


 






    	 	10	 



     


    

 


Options
at such time as the Board deems appropriate. Such surrender or termination shall take place as of the date of the Change of Control or
such other date as the Board may specify. The Board shall have no obligation to take any of the foregoing actions, and, in the absence
of any such actions, outstanding Options and Stock Awards shall continue in effect according to their terms (subject to any assumption
pursuant to subsection (b)).


 


11.            Requirements
for Issuance of Shares.


 


(a)            Stockholders
Agreement/Voting Agreement. The Board may require that a Grantee execute a stockholders agreement
and/or a voting agreement, in each case, with such terms as the Board deems appropriate, with respect to any Company Stock issued pursuant
to this Plan.


 


(b)            Limitations
on Issuance of Shares. No Company Stock shall be issued in connection with any Grant hereunder
unless and until all legal requirements applicable to the issuance of such Company Stock have been complied with to the satisfaction of
the Board. The Board shall have the right to condition any Grant made to any Grantee hereunder on such Grantee’s undertaking in
writing to comply with such restrictions on his or her subsequent disposition of such shares of Company Stock as the Board shall deem
necessary or advisable, and certificates representing such shares may be legended to reflect any such restrictions. Certificates representing
shares of Company Stock issued under this Plan will be subject to such stop-transfer orders and other restrictions as may be required
by applicable laws, regulations and interpretations, including any requirement that a legend be placed thereon.


 


(c)            Lock-Up
Period. If so requested by the Company or any representative of the underwriters (the “Managing
Underwriter”) in connection with any underwritten offering of securities of the Company under the Securities Act of 1933, as amended
(the “Securities Act”), a Grantee (including any successor or assigns) shall not sell or otherwise transfer any shares or
other securities of the Company during the 30-day period preceding and the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act for such underwriting (or such shorter period as may be requested by the Managing
Underwriter and agreed to by the Company) (the “Market Standoff Period”). If so requested, the Grantee shall enter into a
separate written agreement to such effect in form and substance requested by the Company or the Managing Underwriter. The Company may
impose stoptransfer instructions with respect to securities subject to the foregoing restrictions until the end of such Market Standoff
Period. Notwithstanding the foregoing, the Company may require that a Grantee execute a Stockholders Agreement or other agreement containing
lock-up provisions. If such Stockholders Agreement or other agreement contains any lock-up or market standoff provisions that differ from
the provisions of this Section 11(c), for as long as the provisions of such other agreement are in effect, the provisions of this
Section 11(c) shall not apply to such Company Stock, unless the Board determines otherwise.


 


12.            Amendment
and Termination of This Plan.


 


(a)            Amendment.
The Board may amend or terminate this Plan at any time; provided, however, that the Board shall
not amend this Plan without stockholder approval if such


 






    	 	11	 



     


    

 


approval is required in order to comply with the Code or other applicable laws,
or, after a Public Offering, to comply with applicable stock exchange requirements.


 


(b)            Termination
of This Plan. This Plan shall terminate on the day immediately preceding the tenth anniversary
of its effective date, unless this Plan is terminated earlier by the Board or is extended by the Board with the approval of the stockholders.


 


(c)            Termination
and Amendment of Outstanding Grants. A termination or amendment of this Plan that occurs
after a Grant is made shall not materially impair the rights of a Grantee unless the Grantee consents or unless the Board acts under Section 18(b).
The termination of this Plan shall not impair the power and authority of the Board with respect to an outstanding Grant. Whether or not
this Plan has terminated, an outstanding Grant may be terminated or amended under Section 18(b) or may be amended by agreement
of the Company and the Grantee consistent with this Plan.


 


(d)            Governing
Document. This Plan shall be the controlling document. No other statements, representations,
explanatory materials or examples, oral or written, may amend this Plan in any manner. This Plan shall be binding upon and enforceable
against the Company and its successors and assigns.


 


13.            Funding
of This Plan. This Plan shall be unfunded. The Company shall not be required to establish
any special or separate fund or to make any other segregation of assets to assure the payment of any Grants under this Plan. In no event
shall interest be paid or accrued on any Grant, including unpaid installments of Grants.


 


14.            Rights
of Participants. Nothing in this Plan shall entitle any Employee, Key Advisor, Non-Employee
Director or other person to any claim or right to be granted a Grant under this Plan. Neither this Plan nor any action taken hereunder
shall be construed as giving any individual any rights to be retained by or in the employ of the Employer or any other employment rights.


 


15.            No
Fractional Shares. No fractional shares of Company Stock shall be issued or delivered pursuant
to this Plan or any Grant. The Board shall determine whether cash, other awards or other property shall be issued or paid in lieu of such
fractional shares or whether such fractional shares or any rights thereto shall be forfeited or otherwise eliminated.


 


16.            Headings.
Section headings are for reference only. In the event of a conflict between a title and
the content of a Section, the content of the Section shall control.


 


17.            Effective
Date of this Plan.


 


(a)            Effective
Date. The 2007 Equity Incentive Plan of the Company was originally effective as of October 1,
2007. This Plan shall be effective as of January 10, 2017.


 


(b)            Public
Offering. The provisions of this Plan that refer to a Public Offering, or that refer to,
or are applicable to persons subject to, section 16 of the Exchange Act or section 162(m) of the Code, shall be effective, if at
all, upon the initial registration of the Company


 






    	 	12	 



     


    

 


Stock under section 12(g) of the Exchange Act, and shall remain
effective thereafter for as long as such stock is so registered.


 


18.            Miscellaneous.


 


(a)            Grants
in Connection with Corporate Transactions and Otherwise. Nothing contained in this Plan shall
be construed to (i) limit the right of the Board to make Grants under this Plan in connection with the acquisition, by purchase,
lease, merger, consolidation or otherwise, of the business or assets of any corporation, firm or association, including Grants to employees
thereof who become Employees, or for other proper corporate purposes, or (ii) limit the right of the Company to grant stock options
or make other awards outside of this Plan. Without limiting the foregoing, the Board may make a Grant to an employee of another corporation
who becomes an Employee by reason of a corporate merger, consolidation, acquisition of stock or property, reorganization or liquidation
involving the Company, the Parent or any of their subsidiaries in substitution for a stock option or Stock Awards grant made by such corporation.
The terms and conditions of the substitute grants may vary from the terms and conditions required by this Plan and from those of the substituted
stock incentives. The Board shall prescribe the provisions of the substitute grants.


 


(b)            Compliance
with Law. This Plan, the exercise of Options and the obligations of the Company to issue
shares of Company Stock under Grants shall be subject to all applicable laws and to approvals by any governmental or regulatory agency
as may be required. With respect to persons subject to section 16 of the Exchange Act, after a Public Offering it is the intent of the
Company that this Plan and all transactions under this Plan comply with all applicable provisions of Rule 16b-3 or its successors
under the Exchange Act. In addition, it is the intent of the Company that this Plan and applicable Grants under this Plan comply with
the applicable provisions of section 162(m) of the Code, after a Public Offering, and section 422 of the Code. To the extent that
any legal requirement of section 16 of the Exchange Act or section 162(m) or 422 of the Code as set forth in this Plan ceases to
be required under section 16 of the Exchange Act or section 162(m) or 422 of the Code, that Plan provision shall cease to apply.
The Board may revoke any Grant if it is contrary to law or modify a Grant to bring it into compliance with any valid and mandatory government
regulation. The Board may also adopt rules regarding the withholding of taxes on payments to Grantees. The Board may, in its sole
discretion, agree to limit its authority under this Section.


 


(c)            Employees
Subject to Taxation Outside the United States. With respect to Grantees who are subject to
taxation in countries other than the United States, the Board may make Grants on such terms and conditions as the Board deems appropriate
to comply with the laws of the applicable countries, and the Board may create such procedures, addenda and subplans and make such modifications
as may be necessary or advisable to comply with such laws.


 


(d)            Governing
Law. The validity, construction, interpretation and effect of this Plan and Grant Instruments
issued under this Plan shall be governed and construed by and determined in accordance with the laws of the State of Delaware, without
giving effect to the conflict of laws provisions thereof.
