4. Administration of the Plan.

 

(a) Procedure.

 

(A) The Plan shall be administered
by the Board. The Board may appoint a Committee consisting of not less than two (2) members of the Board to administer the Plan, subject
to such terms and conditions as the Board may prescribe. Once appointed, the Committee shall continue to serve until otherwise directed
by the Board. From time to time, the Board may increase the size of the Committee and appoint additional members thereof; remove members
(with or without cause) and appoint new members in substitution therefor; fill vacancies, however caused; and remove all members of the
Committee; and, thereafter, directly administer the Plan.

 

(B) Members of the Board or
Committee, who are either eligible for Options or have been granted Options, may vote on any matters affecting the administration of the
Plan or the grant of Options pursuant to the Plan, except that no such member shall act upon the granting of an Option to himself, but
any such member may be counted in determining the existence of a quorum at any meeting of the Board or the Committee during which action
is taken with respect to the granting of an Option to him or her.

 

    -4-

     

    

 

(C) The Committee shall meet at such
times and places and upon such notice as the chairperson of the Committee determines. A majority of the Committee shall constitute a
quorum. Any acts by the Committee may be taken at any meeting at which a quorum is present and shall be by majority vote of those members
entitled to vote. Additionally, any acts reduced to writing or approved in writing by all of the members of the Committee shall be valid
acts of the Committee.

 

(b) Procedure After Registration
Date. Notwithstanding subsection (a) above, after the date of registration of the Company’s Common Stock on a national securities
exchange or the Registration Date, the Plan shall be administered either by: (i) the full Board; or (ii) a Committee of two (2) or more
directors, each of whom is a Non-Employee Director. After such date, the Board shall take all action necessary to administer the Plan
in accordance with the then effective provisions of Rule 16b-3 promulgated under the Exchange Act; provided that any amendment
to the Plan required for compliance with such provisions shall be made consistent with the provisions of Section 13 of the Plan and applicable
regulations.

 

(c) Procedure After Section
162(m) Effective Date. Notwithstanding subsections (a) and (b) immediately above, after the Section 162(m) Effective Date, the Plan and all Option grants shall be administered
and approved by a Committee comprised solely of two or more Outside Directors.

 

(d) Powers of the Committee.
Subject to the provisions of the Plan, the Committee shall have the authority: (i) to determine, upon review of relevant information,
the Fair Market Value of the Common Stock; (ii) to determine the exercise price of Options to be granted; the Employees, Non-Employee
Directors or Consultants to whom and the time or times at which Options shall be granted; and the number of Shares to be represented by
each Option; (iii) to interpret the Plan; (iv) to prescribe, amend and rescind rules and regulations relating to the Plan; (v) to determine
the terms and provisions of each Option granted under the Plan (which need not be identical) and, with the consent of the holder thereof,
to modify or amend any Option; (vi) to authorize any individual to execute on behalf of the Company any instrument required to effectuate
the grant of an Option previously granted by the Committee; (vii) to determine whether Options granted under the Plan will be Incentive
Stock Options or Non-Statutory Stock Options; (viii) to extend an Option exercise period, subject to Section 7(a) and 7(b) hereof, and
(ix) to make all other determinations deemed necessary or advisable for the administration of the Plan.

 

(e) Acceleration of Vesting.
In addition to its other powers, the Board (or the Committee), in its discretion, has the right, but not the obligation, to accelerate
unvested Options in connection with (i) any tender offer for a majority of the outstanding shares of Common Stock by any Person; (ii)
any proposed sale or conveyance of all or substantially all of the property and assets of the Company; or (iii) any proposed consolidation
or merger of the Company with or into any other corporation, unless the Company is the surviving corporation. In the case of such accelerated
vesting, the Company shall give written notice to the holder of any Option that such Option may be exercised even though the Option or
portion thereof would not otherwise have been exercisable had the foregoing event not occurred. In such event, the Company shall permit
the holder of any Option to exercise during the time period specified in the Company’s notice, which period shall not be less than
ten (10) days following the date of notice. Upon consummation of a tender offer or proposed sale, conveyance, consolidation or merger
to which such notice shall relate, all rights under the Option which shall not have been so exercised shall terminate unless the agreement
governing the transaction shall provide otherwise.

 

    -5-

     

    

 

(f) Effect of Committee’s Decision.
All decisions, determinations and interpretations of the Committee shall be final and binding on all potential and actual Optionees,
any other holder of an Option or other equity security of the Company, and all other Persons.

 

5. Eligibility.

 

(a) Persons Eligible for Options.
Options under the Plan may be granted only to Employees, Non-Employee Directors or Consultants whom the Committee, in its sole discretion,
may designate from time to time. Incentive Stock Options may be granted only to Employees. An Employee who has been granted an Option,
if he or she is otherwise eligible, may be granted an additional Option or Options.

 

(b) No Right to Grant; No Uniformity.
No Employee, Non-Employee Director, or Consultant shall have any claim to be granted an Option under the Plan, and there is no obligation
for uniformity of treatment of Employees, Non-Employee Directors, or Consultants under the Plan.

 

(c) Additional Limitations.

 

(A) The aggregate Fair Market
Value (determined as of the time each respective Incentive Stock Option is granted) of Shares with respect to which Incentive Stock Options
are exercisable for the first time by any Optionee during any calendar year (under all plans of the Company and its Parent and Subsidiary
companies) shall not exceed the sum of $100,000. In the event that the Incentive Stock Option, or portion thereof, shall exceed the sum
of $100,000 as provided in the preceding sentence, such excess portion shall be treated as Non-Statutory Stock Options.

 

(B) As of the Section 162(m)
Effective Date, Options under the Plan shall be granted to Covered Employees upon satisfaction of the conditions to such grants provided
pursuant to Section 162(m) and any Treasury Regulations promulgated thereunder.

 

(d) No Right to Continuing
Employment. Neither the establishment nor the operation of the Plan shall confer upon any Optionee or any other Person any right
with respect to continuation of employment or other service with the Company, any Parent of the Company, any Subsidiary of the
Company, or any Subsidiary of any Parent of the Company, nor shall the Plan interfere in any way with the right of the Optionee or
the right of the Company (or of any Parent of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the
Company) to terminate such employment or service at any time, with or without cause.

 

6. Term of Plan. The
Plan shall become effective upon its adoption by the Board or its approval by vote of the holders of the outstanding shares of the Company
entitled to vote on the adoption of the Plan (in accordance with the provisions of Section 19 hereof), whichever is earlier. It shall
continue in effect for a term of ten (10) years unless sooner terminated under Section 13 of the Plan. No Option shall be granted under
the Plan after the close of business on the day immediately preceding the tenth (10th) anniversary of the effective date of the Plan,
or if earlier, the tenth (10th) anniversary of the date this Plan is approved by the stockholders. Subject to other applicable provisions
of the Plan, all Options granted under the Plan prior to such termination of the Plan shall remain in effect until such Options have
been exercised or terminated in accordance with the Plan and the terms of such Options.

 

    -6-

     

    

 

7. Term of Option.

 

(a) In General. The term
of each Option granted under the Plan shall be determined by the Committee and shall be no more than ten (10) years from the date of grant
of such Option. The term of the Option shall be set forth in the Option Agreement (if not set forth in the Option Agreement, then the
term shall be ten (10) years from the date of grant).

 

(b) Incentive Stock Options.
No Incentive Stock Option shall be exercisable after the expiration of ten (10) years from the date such Option is granted; provided
that no Incentive Stock Option granted to any Employee who, at the date such Option is granted, owns (within the meaning of Section
424(d) of the Code) more than ten percent (10%) of the total combined voting power of all classes of stock of the Company, any Parent
of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the Company shall be exercisable after the expiration
of five (5) years from the date such Option is granted.

 

8. Exercise Price and Consideration.

 

(a) Exercise Price. Except
as provided in subsection (b) below, the exercise price for the Shares to be issued pursuant to any Option shall be such price as is determined
by the Committee, which shall in no event be less than one hundred percent (100%) of the Fair Market Value of such Shares on the date
the Option is granted.

 

(b) Incentive Stock Options
Granted to Ten Percent Stockholders. No Incentive Stock Option shall be granted to any Employee who, at the date such Option is granted,
owns (within the meaning of Section 424(d) of the Code) more than ten percent (10%) of the total combined voting power of all classes
of stock of the Company, any Parent of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the Company, unless
the exercise price for the Shares to be issued pursuant to such Option is at least equal to one hundred ten percent (110%) of the Fair
Market Value of such Shares on the grant date.

 

(c) Consideration. The
consideration to be paid for the Shares shall be payment in cash or by check unless payment in some other manner, including by promissory
note, other shares of the Company’s Common Stock or such other consideration and method of payment for the issuance of Shares as
may be permitted under the Delaware General Corporation Law, is authorized by the Committee at the time of the grant of the Option and
specified in the Option Agreement. Any cash or other property received by the Company from the sale of Shares pursuant to the Plan shall
constitute part of the general assets of the Company.

 

(d) Loans. To the extent
permitted by law, the Company may make or guarantee loans to Optionees to assist Optionees in exercising Options and satisfying any withholding
tax obligations.

9. Exercise of Option.

 

(a) Vesting Period. Any Option
granted hereunder shall be exercisable at such times and under such conditions as determined by the Committee and as shall be permissible
under the terms of the Plan, which shall be specified in the Option Agreement evidencing the Option.

 

(b) Exercise Procedures.

 

(A) An Option shall be deemed
to be exercised when written notice of such exercise has been given to the Company in accordance with the terms of the Option Agreement
evidencing the Option, and full payment for the Shares with respect to which the Option is exercised has been received by the Company.
After the Registration Date, in lieu of delivery of a cash payment for the purchase price of the Shares with respect to which the Option
is exercised, the Optionee may deliver to the Company a sell order to a broker for the Shares being purchased and an agreement to pay
(or have the broker remit payment for) the purchase price for the Shares being purchased on or before the settlement date for the sale
of such shares to the broker.

 

(B) Pursuant to the terms
of the Option Agreement, the Committee may, but is not obligated to require that any Option may be exercised only upon the execution of
a stock restriction agreement which gives the Company a right to repurchase the Option Shares at the lesser of the Fair Market Value of
the Shares at the date of repurchase or their original exercise price. Any such stock restriction agreement shall contain such other provisions
as the Committee may approve in its sole discretion.

 

(C) An Option may not be exercised
for fractional shares. As soon as practicable following the exercise of an Option in the manner set forth above, the Company shall issue
or cause its transfer agent to issue stock certificates representing the Shares purchased. Until the issuance of such stock certificates
(as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to
vote or receive dividends or any other rights as a stockholder shall exist with respect to the Shares notwithstanding the exercise of
the Option. No adjustment will be made for a dividend or other rights for which the record date is prior to the date of the transfer by
the Optionee of the consideration for the purchase of the Shares, except as provided in Section 11 of the Plan. After the Registration
Date, the exercise of an Option by any Optionee subject to short-swing trading liability under Section 16(b) of the Exchange Act shall
be subject to compliance with all applicable requirements of Rule 16b-3 promulgated under the Exchange Act.

 

(c) Death of Optionee.
In the event of the death during the Option period of an Optionee who is at the time of his death, or was within the ninety (90)-day
period immediately prior thereto, an Employee or Non-Employee Director, and who was in Continuous Employment as such from the date of
the grant of the Option until the date of termination or death, this Option may be exercised, at any time within one (1) year following
the date of death, by the Optionee’s estate or by any Person who acquired the right to exercise the Option by bequest or inheritance,
but only to the extent of the accrued right to exercise at the time of the termination or death, whichever comes first, subject to the
condition that no Option shall be exercised after the expiration of the term of the Option.

 

    -8-

     

    

 

(d) Disability of Optionee.
In the event of the permanent and total disability during the Option period of an Optionee who is at the time of such disability, or was
within the ninety (90)-day period prior thereto, an Employee or Non-Employee Director, and who was in Continuous Employment as such from
the date of the grant of the Option until the date of disability or termination, the Option may be exercised at any time within one (1)
year following the date of such permanent and total disability, but only to the extent of the accrued right to exercise at the time of
the termination or disability, whichever comes first, subject to the condition that no Option shall be exercised after the expiration
of the term of the Option.

 

(e) Termination of Status
as Employee, Non-Employee Director or Consultant. If an Optionee shall cease to be an Employee or Non-Employee Director for any reason
other than permanent and total disability or death and at such time also cease to be in Continuous Employment, or if an Optionee shall
cease to be a Consultant for any reason and at such time also cease to be in Continuous Employment, the Optionee may, but only within
thirty (30) days (or such other period of time as is determined by the Committee) after such date exercise his or her Option to the extent
that the Optionee was entitled to exercise it at the date of such termination, subject to the condition that no Option shall be exercisable
after the expiration of the term of the Option; provided, however, that if an Optionee shall cease to be an Employee, Non-Employee
Director or Consultant during the Option period due to termination for Cause, the Option shall terminate in its entirety, and shall not
be exercisable whatsoever, upon such termination for Cause, regardless of whether the Option was exercisable immediately prior to such
termination.

 

(f) Exercise of Option with
Stock After Registration Date. After the Registration Date, the Committee may permit an Optionee to exercise an Option by delivering
shares of the Company’s Common Stock. If the Optionee is so permitted, the Option Agreement covering such Option may include provisions
authorizing the Optionee to exercise the Option, in whole or in part, by: (i) delivering whole shares of the Company’s Common Stock
previously owned by such Optionee (whether or not acquired through the prior exercise of a stock option) having a Fair Market Value equal
to the aggregate exercise price for the Shares issuable on exercise of the Option; and/or (ii) directing the Company to withhold from
the Shares that would otherwise be issued upon exercise of the Option that number of whole Shares having a Fair Market Value equal to
the aggregate exercise price for the Shares issuable on exercise of the Option. Shares of the Company’s Common Stock so delivered
or withheld shall be valued at their Fair Market Value at the close of the last business day immediately preceding the date of exercise
of the Option, as determined by the Committee. Any balance of the exercise price shall be paid in cash. Any shares delivered or withheld
in accordance with this provision shall not again become available for purposes of the Plan and for Options subsequently granted thereunder.

 

(g) Taxes.

 

(A) The Company shall be authorized
to report all income with respect to an Option.

 

(B) Before the Registration
Date, an Optionee, whether or not a current Employee, shall pay to the Company in cash the amount of his or her tax withholding obligations
in connection with the exercise of an Option as determined by the Company in its sole discretion. The Company shall be authorized to
deduct, to the extent permitted by law, any tax obligations required to be withheld in respect of an Option from any payment of any kind
otherwise due to an Optionee and take such other action as may be necessary in the opinion of the Company to satisfy all withholding
obligations.

 

    -9-

     

    

 

(C) After the Registration
Date, an Optionee, whether or not a current Employee, shall pay to the Company the amount of his or her tax withholding obligations in
connection with the exercise of an Option as determined by the Company in its sole discretion. The Optionee may elect prior to the date
the amount of such withholding tax is determined (the “Tax Date”) to make such payment, or such increased payment
as the Optionee elects to make up to the maximum Federal, state and local marginal tax rates, including any related FICA obligation, applicable
to the Optionee and the particular transaction, by: (i) delivering cash; (ii) delivering part or all of the payment in previously owned
shares of Common Stock (whether or not acquired through the prior exercise of an Option); and/or (iii) irrevocably directing the Company
to withhold from the Shares that would otherwise be issued upon exercise of the Option that number of whole Shares having a Fair Market
Value equal to the amount of tax required or elected to be withheld (a “Withholding Election”). If an Optionee’s
Tax Date is deferred beyond the date of exercise and the Optionee makes a Withholding Election, the Optionee will initially receive the
full amount of Shares otherwise issuable upon exercise of the Option, but will be unconditionally obligated to surrender to the Company
on the Tax Date the number of Shares necessary to satisfy his or her minimum withholding requirements, or such higher payment as he or
she may have elected to make, with adjustments to be made in cash after the Tax Date.

 

(D) Any withholding of Shares
with respect to taxes arising in connection with the exercise of an Option by any Optionee subject to short-swing trading liability under
Section 16(b) of the Exchange Act shall satisfy the requirements of Section 16b-3(e).

 

(E) Any adverse consequences
incurred by an Optionee with respect to the use of shares of Common Stock to pay any part of the exercise price or of any tax in connection
with the exercise of an Option, including without limitation any adverse tax consequences arising as a result of a disqualifying disposition
within the meaning of Section 422 of the Code shall be the sole responsibility of the Optionee. Shares withheld in accordance with this
provision shall not again become available for purposes of the Plan and for Options subsequently granted thereunder.

 

10. Non-Transferability
of Options. An Option may not be sold, pledged, assigned, hypothecated, transferred or disposed of in any manner other than by will
or by the laws of descent and distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee.

 

11. Adjustments Upon Changes
in Capitalization.

 

(a) Proportionate Adjustments.
Subject to any required action by the stockholders of the Company, the number of Shares covered by each outstanding Option, and the
per share exercise price of each such Option, shall be proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, recapitalization, combination, reclassification, the payment
of a stock dividend on the Common Stock or any other increase or decrease in the number of such shares of Common Stock effected without
receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall
not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose
determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue 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 of Common Stock subject to an Option.

 

    -10-

     

    

 

(b) Equitable Adjustments.
The Committee shall equitably adjust the number or class of securities covered by any Option, as well as the price to be paid therefor,
in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings, or other increases or reductions
of shares of its outstanding Common Stock, and in the event of the Company being consolidated with or merged into any other corporation.

 

(c) Adjustments for Unusual
or Nonrecurring Events. The Committee is authorized to make, in its discretion and without the consent of Optionees, adjustments in
the terms and conditions of, and the criteria included in, Options in recognition of unusual or nonrecurring events affecting the Company,
or the financial statements of the Company, or of changes in applicable laws, regulations, or accounting principles, whenever the Committee
determines that such adjustments are appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended
to be made available under the Plan.

 

(d) Termination Upon Dissolution
or Liquidation. Unless otherwise

determined by the Committee, upon the dissolution or liquidation of the Company, the Options granted under the Plan shall terminate and
thereupon become null and void. The Optionee shall be given not less than ten (10) days’ notice of such event and the opportunity
to exercise each outstanding Option before such event is effected.

 

(e) Adjustment Upon Merger
or Consolidation. Except to the extent provided otherwise in an Option Agreement, upon a merger or consolidation of the Company all
outstanding Options held by an Optionee may, in the sole discretion of the Committee, be (i) immediately vested and exercisable, (ii)
cancelled and the Optionee paid the amount by which the Fair Market Value of the Shares exceeds the exercise price, or (iii) assumed by,
or converted to options of the surviving corporation or its parent company. A merger or consolidation shall not cause the acceleration
of vesting of Options except to the extent provided under the Plan and in an Option Agreement or other written contract between the Company
and an Optionee.

 

(f) Substitutions Resulting
From Mergers and Acquisitions. Options may be granted under the Plan from time to time in substitution for options held by employees,
officers, consultants or directors of entities who become or are about to become employees, officers, consultants or directors of the
Company, any Parent of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the Company as the result of a
merger or consolidation of the employing entity with the Company, any Parent of the Company, any Subsidiary of the Company, or any Subsidiary
of any Parent of the Company, or the acquisition by the Company or by any Parent of the Company, any Subsidiary of the Company, or any
Subsidiary of any Parent of the Company of the assets or stock of the employing entity. The terms and conditions of any substitute Options
so granted may vary from the terms and conditions set forth herein to the extent that the Committee deems appropriate at the time of
grant to conform the substitute Options to the provisions of the options for which they are substituted.

 

    -11-

     

    

 

12. Date of Grant.
References in the Plan to “date of grant,” “the date such Option is granted,” “grant date,” and the
like mean the date the Committee has fixed, for each Option the identity of the Optionee, the maximum number of shares subject to the
Option, and the minimum Option price of the Option. Notice of the grant shall be given to each Optionee to whom an Option is so granted
within a reasonable time after the date of such grant.

 

13. Amendment and Termination
of the Plan. The Board may amend or terminate the Plan, or any portion thereof, from time to time in such respects as the Board may
deem advisable, except that, without approval of the holders of a majority of the outstanding capital stock, no such revision or amendment
shall change the number of Shares subject to the Plan, change the designation of the class of employees eligible to receive Options or
add any material benefit to Optionees under the Plan. Subject to Section 11(e) of the Plan, any such amendment or termination of the Plan
shall not affect Options already granted, and such Options shall remain in full force and effect as if the Plan had not been amended or
terminated. Except as otherwise determined by the Board, termination of the Plan shall not affect the Board’s ability to exercise
the powers granted to it hereunder with respect to Options granted under the Plan prior to the date of such termination. After the Section
162(m) Effective Date, the modification or addition of a material term of the Plan (as determined under Section 162(m) and any applicable
Treasury Regulations promulgated thereunder) shall be approved by the stockholders in the manner provided in Section 19 of the Plan.

 

14. Conditions Upon Issuance
of Shares.

 

(a) Compliance with Law.
Shares shall not be issued with respect to an Option granted under the Plan unless the exercise of such Option and the issuance and delivery
of such Shares pursuant thereto shall comply with all relevant provisions of law, including, without limitation, the Securities Act, the
Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then
be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance.

 

(b) Suspension of Right to
Exercise. If at any time the Committee determines that the issuance and delivery of Common Stock under the Plan is or may be unlawful
under the laws of any applicable jurisdiction, or Federal, state or foreign securities laws, the right to exercise an Option or receive
shares of Common Stock pursuant to an Option shall be suspended until the Committee determines that such issuance and delivery are lawful.
If at any time the Committee determines that the issuance and delivery of Common Stock under the Plan is or may violate the rules of the
national exchange on which the shares of the Company are then listed for trade, the right to exercise an Option or receive shares of Common
Stock pursuant to an Option shall be suspended until the Committee determines that such delivery would not violate such rules. The Company
shall have no obligation to effect any registration or qualification of the Common Stock under Federal, state or foreign laws.

 

    -12-

     

    

 

(c) Representations and
Information. The Company may require that an Optionee, as a condition to exercise of an Option, and as a condition to the delivery
of any share certificate, make such written representations (including representations to the effect that the Shares are being purchased
only for investment and without any present intention to sell or distribute such Shares and that the Optionee will not dispose of the
Common Stock so acquired in violation of Federal, state or foreign securities laws) and furnish such information as may, in the opinion
of counsel for the Company, be appropriate to permit the Company to issue the Common Stock in compliance with applicable Federal, state
or foreign securities laws. The stock certificates for any shares of Common Stock issued pursuant to this Plan may bear a legend restricting
transferability of the shares of Common Stock unless such shares are registered or an exemption from registration is available under
the Securities Act of 1933, as amended, and applicable state or foreign securities laws.

 

(d) Party to Agreements.
Further, as a condition to the grant of any Option, the exercise of such an Option, or to the delivery of certificates for shares
issued pursuant to any Option, the Committee may require the Optionee or the Optionee’s successor or permitted transferee, as the
case may be, to become a party to a stock restriction agreement, stockholders’ agreement, voting trust agreement or other agreement(s)
regarding the Common Stock in such form(s) as the Committee may determine from time to time.

 

15. Reservation of Shares.
During the term of the Plan the Company will at all times reserve and keep available the number of Shares as shall be sufficient to satisfy
the requirements of the Plan. Inability of the Company to obtain from any regulatory body having jurisdiction and authority deemed by
the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder shall relieve the Company of any liability
in respect of the nonissuance or sale of such Shares as to which such requisite authority shall not have been obtained.

 

16. Information to Optionee.
During the term of any Option granted under the Plan, the Company shall provide or otherwise make available to each Optionee a copy of
such financial statements as it generally provides to its stockholders, at least annually; provided, however, that the foregoing
shall not apply to the extent that the Company complies with Rule 701 of the Securities Act with respect to the Plan; provided, further,
that for purposes of determining compliance, any registered domestic partner shall be considered a “family member,” as
that term is defined in Rule 701.

 

17. Option Agreement.
Options granted under the Plan shall be evidenced by Option Agreements.

 

18. Indemnification of
Board (or Committee, if applicable). In addition to such other rights of indemnification as they may have as directors or as members
of the Committee, the members of the Board (or the Committee, if applicable) shall be indemnified by the Company against the reasonable
expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding,
or in connection with any appeal therein, to which they or any of them may be a party by reason of any action taken or failure to act
under or in connection with the Plan or any Option granted thereunder, and against all amounts paid by them in settlement thereof (provided
such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in
any such action, suit or proceeding except in relation to matters as of which it shall be adjudged in such action, suit or proceeding
that such Board (or Committee, if applicable) member is liable for negligence or misconduct in the performance of his duties; provided
that within sixty (60) days after institution of any such action, suit or proceeding a Board (or Committee, if applicable) member
shall in writing offer the Company the opportunity, at its own expense, to handle and defend the same.

 

    -13-

     

    

 

19. Stockholder Approval.
The Plan shall be subject to approval by the affirmative vote of the holders of a majority of the outstanding capital stock of the Company
entitled to vote within twelve (12) months before or after the Plan is adopted. All Options must be cancelled, and any Option exercised
before stockholder approval is obtained must be rescinded, if stockholder approval is not obtained within twelve (12) months before or
after the Plan is adopted. Shares issued upon the exercise of such Options shall not be counted in determining whether such approval is
obtained. Any amendments to the Plan which require stockholder approval shall be by the affirmative vote of the holders of a majority
of the outstanding capital stock of the Company entitled to vote.

 

20. No Deferral. No
Option shall include any feature for the deferral of compensation, other than the deferral of recognition of income until the later of
(i) the exercise of the Option or (ii) the time the Shares acquired pursuant to the exercise of the Option first become substantially
vested (as defined in Treasury Regulation Section 1.83-3(b)).

 

21. No Trust or Fund Created.
Neither the Plan nor any Option shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship
between the Company and an Optionee or any other Person. To the extent that any Optionee or other Person acquires a right to receive payments
from the Company pursuant to an Option, such right shall be no greater than the right of any unsecured general creditor of the Company.

 

22. 409A Savings Clause.
The Plan and all Options granted under the Plan are intended to comply with, or otherwise be exempt from, Section 409A. The Plan and all
Options granted under the Plan shall be administered, interpreted, and construed in a manner consistent with Section 409A to the extent
necessary to avoid the imposition of additional taxes under Section 409A(a)(1)(B). Should any provision of the Plan, any Option Agreement,
or any other agreement or arrangement contemplated by the Plan be found not to comply with, or otherwise be exempt from, Section 409A,
such provision shall be modified and given effect (retroactively if necessary), in the sole discretion of the Committee, and without the
consent of the holder of the Option, in such manner as the Optionee determines to be necessary or appropriate to comply with, or to effectuate
an exemption from, Section 409A. Notwithstanding anything in the Plan to the contrary, in no event shall the Committee exercise its discretion
to accelerate the payment or settlement of an Option where such payment or settlement constitutes deferred compensation within the meaning
of Section 409A unless, and solely to the extent that, such accelerated payment or settlement is permissible under Treasury Regulation
section 1.409A-3(j)(4) or any successor provision. Notwithstanding any other provision of the Plan, although the Board and any designee
of the Board shall use their best efforts to avoid the imposition of taxation, penalties, and interest under Section 409A and other provisions
of the Code, the tax treatment of Options under the Plan shall not be, and is not, warranted or guaranteed. None of the Company, the Board,
the Committee, or any of their designees shall be held liable for any taxes, penalties, or other monetary amounts owed by an Employee,
Non-Employee Director, Consultant, Optionee, beneficiary, or other Person as a result of any exercise, purchase, or payment under the
Plan or the administration of the Plan.

 

    -14-

     

    

 

23. Disqualifying Dispositions.
If Shares of Common Stock acquired upon exercise of an Incentive Option are disposed of within two (2) years following the date of grant
or one (1) year following the transfer of such Shares to an Employee or former Employee, the Employee or former Employee shall within
fifteen (15) days following such disposition notify the Company in writing of such disposition and provide such other information regarding
the disposition as the Company may reasonably require.

 

24. Severability. If
any provision of the Plan is or becomes or is deemed invalid, illegal, or unenforceable in any jurisdiction, or would disqualify the Plan
or any Option under any applicable law, such provision shall be construed or deemed amended to conform to applicable laws or if it cannot
be construed or deemed amended without materially altering the intent of the Plan, it shall be stricken and the remainder of the Plan
shall remain in full force and effect.

 

25. Governing Law.
The validity, construction and effect of the Plan, of Option Agreements entered into pursuant to the Plan, and of any rules, regulations,
determinations or decisions made by the Committee relating to the Plan or such Option Agreements, and the rights of any and all Persons
having or claims to have any interest therein or thereunder, shall be determined exclusively in accordance with applicable Federal laws
and the laws of the State of Delaware, without regard to its conflict of laws principles.

 

26. Effective Date; Termination
Date. The Plan is effective as of the date on which the Plan is adopted by the Board, subject to approval of the stockholders of the
Company within twelve (12) months before or after such date.

2. Method of Exercise.

 

(a) Notice. Optionee
may exercise this Option by delivering a signed Notice of Exercise in substantially the form attached hereto as Exhibit B to the
officer of the Company designated in such form of Notice. Such Notice of Exercise shall be accompanied by payment in full of the aggregate
purchase price for the Shares as provided in Section 2(c) of this Agreement.

 

(b) Restriction on Exercise.
This Option may not be exercised if the issuance of the Shares upon such exercise or the method of payment of consideration for such Shares
would constitute a violation of any applicable Federal or state securities law or any other law or regulation. Furthermore, the method
and manner of payment of the Option Price will be subject to the rules under Part 207 of Title 12 of the Code of Federal Regulations (“Regulation
G”) as promulgated by the Federal Reserve Board if such rules apply to the Company at the date of exercise. As a condition
to the exercise of this Option, the Company may require Optionee to make any representation or warranty to the Company at the time of
exercise of the Option as in the opinion of legal counsel for the Company may be required by any applicable law or regulation, including
the execution and delivery of an appropriate representation statement. Accordingly, the stock certificates for the Shares issued upon
exercise of this Option may bear appropriate legends restricting transfer.

 

(c) Method of Payment.
Payment of the exercise price shall be by any of the following, or a combination thereof, at the election of Optionee:

 

(i) cash;

 

(ii) certified or bank cashier’s
check; or

 

(iii) in the event there exists
a public market for the Company’s Common Stock on the date of exercise, by surrender of outstanding shares of the Company’s

the holding period requirements under Section 422(a)(1) of the Code. If payment is made with shares of stock already owned by Optionee,
payment shall be made as follows:

 

(A)
Optionee shall deliver to the officer of the Company designated in the form of Notice of Exercise a written notice which shall set forth
the portion of the purchase price Optionee wishes to pay with Common Stock, and the number of outstanding shares of such Common Stock
Optionee intends to surrender pursuant to the exercise of this Option, which shall be determined by dividing the aforementioned portion
of the purchase price by the Fair Market Value per Share of the Common Stock at the close of the last business day immediately preceding
the date of exercise of the Option, as determined by the Committee;

 

    -2-

from the date of the Notice of Exercise;

 

(D) Optionee hereby authorizes
and directs the Secretary of the Company to transfer so many of the outstanding shares represented by such certificate(s) and to record
the transfer to the Company of such shares in the books of the Company or its transfer agent as are necessary to pay the purchase price
in accordance with the provisions herein;

 

(E) If any such transfer of
outstanding shares requires the consent of any governmental agency under the securities laws of any state, or an opinion of counsel for
the Company or Optionee that such transfer may be effected under applicable Federal and state securities laws, the time periods specified
herein shall be extended for such periods as the necessary request for consent to transfer is pending before said Commission or other
agency, or until counsel renders such an opinion, as the case may be. All parties agree to cooperate in making such request for transfer,
or in obtaining such opinion of counsel, and no transfer shall be effected without such consent or opinion if required by law; and

 

(F) Notwithstanding any other
provision herein, Optionee shall be permitted to pay the purchase price only with shares of the Company’s Common Stock owned by
him as of the exercise date and only in the manner and within the time periods allowed under 17 CFR § 240.16b-3 promulgated under
the Securities Exchange Act of 1934 as such regulation is presently constituted, as it is amended from time to time, and as it is interpreted
now or hereafter by the Securities and Exchange Commission.

 

(d) Agreement to Execute Other
Agreements. Optionee agrees to execute, as a condition precedent to the exercise of the Option and at any time thereafter as may
reasonably be requested by the Board, any and all agreements that may be common among some or all of the Company’s
stockholders, including, without limitation, a stockholders agreement and a voting agreement (collectively, the
“Stockholders Agreements”), with respect to any shares Optionee acquired pursuant to this Agreement, provided,
however, that execution of such Stockholders Agreements will not be required upon any exercise that occurs after the closing of
the first public offering of capital stock of the Company that is effected pursuant to a registration statement filed with, and
declared effective by, the Securities and Exchange Commission under the Securities Act or, if later, the expiration of any market
stand-off agreement that applies to other stockholders of the Company with respect to such public offering of capital stock.

 

3. Term and Expiration. This
Option, if it has not earlier expired pursuant to the terms of this Agreement or the Plan, shall expire in all events on the tenth (10th)
anniversary of the Date of Grant set forth on the first page hereof.

 

    -3-

     

    

 

4. Compliance with State
and Federal Securities Laws. No Shares shall be issued upon the exercise of this Option unless and until the Company has determined
that all applicable provisions of state and Federal securities laws have been satisfied.

 

5. Adjustment Upon Changes
in Capitalization or Merger. The number of Shares covered by this Option shall be adjusted in accordance with the provisions of Section
11 of the Plan in the event of changes in the capitalization or organization of the Company, or if the Company is a party to a merger
or other corporate reorganization.

 

6. Not Employment Contract.
Nothing in this Agreement or in the Plan shall confer upon Optionee any right to continue in the employ of or as a service provider to
the Company (or of any Parent of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the Company) or shall
interfere with or restrict in any way the rights of the Company (or of any Parent of the Company, any Subsidiary of the Company, or any
Subsidiary of any Parent of the Company), which are hereby expressly reserved, to discharge Optionee at any time for any reason whatsoever,
with or without cause, subject to the provisions of applicable law. This is not an employment or service provider contract.

 

7. Income Tax Withholding.
Optionee authorizes the Company to report income and to withhold in accordance with applicable law from any compensation payable to him
or her any and all taxes required to be withheld by Federal, state, local and/or foreign laws as a result of the exercise of this Option
and further agrees that the Company and the Company’s agents shall not be required to deliver any shares purchased by Optionee upon
exercise of this Option unless and until Optionee’s tax obligations have been satisfied to the Company’s satisfaction or Optionee
has provided the Company with such payments. Optionee understands and agrees that the Company may require Optionee to make a cash payment
to cover any withholding tax obligations as a condition of exercise of the Option. Furthermore, in the event of any determination that
the Company has failed to withhold a sum sufficient to pay all withholding taxes due in connection with the exercise of this Option, Optionee
agrees to pay the Company the amount of any such deficiency in cash within five (5) days after receiving a written demand from the Company
to do so, whether or not Optionee is an Employee or service provider of the Company at that time. In addition, to ensure compliance with
applicable state corporate law, the Company may require Optionee to furnish consideration in the form of cash or cash equivalents equal
to the par value of the Shares issued upon exercise of this Option, and Optionee hereby authorizes the Company to withhold such amount
from remuneration otherwise due Optionee from the Company.

 

8. Market Stand-Off
Agreement. Optionee agrees that following the effective date of a registration statement of the Company filed under the
Securities Act, Optionee, for the duration specified by and to the extent requested by the Company and an underwriter of Common
Stock or other securities of the Company, shall not offer, sell, contract to sell, pledge or otherwise dispose of, directly or
indirectly, any equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such
securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that
transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned
transaction is to be settled by delivery of such securities or other securities, in cash or otherwise, or publicly disclose the
intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other
arrangement, in each case during the seven (7) days prior to and the one hundred eighty (180) days after the effectiveness of any
underwritten offering of the Company’s equity securities (or such longer or shorter period as may be requested in writing by
the managing underwriter and agreed to in writing by the Company) (the “Market Stand-Off Period”), except
as part of such underwritten registration if otherwise permitted. In addition, Optionee agrees to execute any further letters,
agreements and/or other documents requested by the Company or its underwriters that are consistent with the terms of this Section 8.
The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of
such Market Stand-Off Period.

the name of Optionee.

 

(b) Electronic Delivery of

(c) Resolution of Disputes.
Optionee acknowledges and agrees that the Plan is and shall be administered in accordance with Section 4 of the Plan and that all decisions,
determinations and interpretations of the Committee shall be final and binding on all potential and actual Optionees (including Optionee),
any and all other holders of an Option or other equity security of the Company, and all other persons. Optionee agrees that before Optionee
may bring any legal action arising under, as a result of, pursuant to or relating to, this Agreement or the Plan, Optionee will first
exhaust Optionee’s administrative remedies before the Committee. Optionee further agrees that in the event that the Committee does
not resolve any dispute or disagreement arising under, as a result of, pursuant to or relating to, this Agreement or the Plan to Optionee’s
satisfaction, no legal action may be commenced or maintained relating to this Agreement or the Plan more than twenty-four (24) months
after the Committee’s decision.

(e) Governing Law. This
Agreement and the rights and duties of the parties hereunder shall be governed and controlled as to validity, enforcement, interpretation,

This Agreement and the Plan supersede all other prior agreements, communications, and statements, whether written or oral, express or
implied, pertaining to that subject matter. This Agreement and the Plan may not be contradicted by evidence of any prior or contemporaneous
statements or agreements, oral or written, and may not be explained or supplemented by evidence of consistent additional terms.

 

(g) Counterparts. This
Agreement may be executed in one or more counterparts all of which together shall constitute one and the same instrument.

understands that what constitutes Service Provider status, other than as an officer, employee or consultant as set forth above,
shall be determined entirely by the Board of Directors and the decision of such Board shall be final. Options shall be rounded down
to the nearest whole Share.

 

(b) In the event of Optionee’s
death, disability or other termination of Service Provider status, the exercisability of this Option shall be governed by Sections 9(c),
9(d) and 9(e) of the Plan.

 

    -1-

     

    

 

(c) The Option may not be exercised
for fractional shares or for less than one hundred (100) Shares unless the remaining number of Shares subject to exercise is less
than one hundred (100).

 

1. No Transfer or Assignment
of Option. This Option and the rights and privileges conferred hereby shall not be transferred, assigned, pledged, or hypothecated
in any way (whether by operation of law or otherwise) and shall not be subject to sale under execution, attachment, or similar process.
Upon any attempt to transfer, assign, pledge, hypothecate, or otherwise dispose of this option, or of any right or privilege conferred
hereby, contrary to the provisions of this Agreement, or upon any attempted sale under any execution, attachment, or similar process upon
the rights and privileges conferred hereby, this Option and the rights and privileges conferred hereby shall immediately become null and
void.

 

2. Method of Exercise.

 

(a) Notice. Optionee
may exercise this Option by delivering a signed Notice of Exercise in substantially the form attached hereto as Exhibit B to the
officer of the Company designated in such form of Notice. Such Notice of Exercise shall be accompanied by payment in full of the aggregate
purchase price for the Shares as provided in Section 2(c) of this Agreement.

 

(b) Restriction on Exercise.
This Option may not be exercised if the issuance of the Shares upon such exercise or the method of payment of consideration for such Shares
would constitute a violation of any applicable Federal or state securities law or any other law or regulation. Furthermore, the method
and manner of payment of the Option Price will be subject to the rules under Part 207 of Title 12 of the Code of Federal Regulations (“Regulation
G”) as promulgated by the Federal Reserve Board if such rules apply to the Company at the date of exercise. As a condition
to the exercise of this Option, the Company may require Optionee to make any representation or warranty to the Company at the time of
exercise of the Option as in the opinion of legal counsel for the Company may be required by any applicable law or regulation, including
the execution and delivery of an appropriate representation statement. Accordingly, the stock certificates for the Shares issued upon
exercise of this Option may bear appropriate legends restricting transfer.

 

(c) Method of Payment.
Payment of the exercise price shall be by any of the following, or a combination thereof, at the election of Optionee:

 

(i) cash;

 

(ii) certified or bank cashier’s
check; or

 

    -2-

     

    

 

(iii) in the event there exists
a public market for the Company’s Common Stock on the date of exercise, by surrender of outstanding shares of the Company’s
Common Stock; provided that if such shares were acquired upon exercise of an incentive stock option, Optionee must have first satisfied
the holding period requirements under Section 422(a)(1) of the Code. If payment is made with shares of stock already owned by Optionee,
payment shall be made as follows:

 

(A) Optionee shall deliver to
the officer of the Company designated in the form of Notice of Exercise a written notice which shall set forth the portion of the purchase
price Optionee wishes to pay with Common Stock, and the number of outstanding shares of such Common Stock Optionee intends to surrender
pursuant to the exercise of this Option, which shall be determined by dividing the aforementioned portion of the purchase price by the
Fair Market Value per Share of the Common Stock at the close of the last business day immediately preceding the date of exercise of the
Option, as determined by the Committee;

 

(B) Fractional shares shall
be disregarded, and Optionee shall pay any balance in cash;

 

(C) The written notice shall
be accompanied by a duly endorsed blank stock power with respect to the number of outstanding shares set forth in the notice to be surrendered,
and the certificate(s) representing said shares shall be delivered to the Company at its principal offices within three (3) working days
from the date of the Notice of Exercise;

 

(D) Optionee hereby authorizes
and directs the Secretary of the Company to transfer so many of the outstanding shares represented by such certificate(s) and to record
the transfer to the Company of such shares in the books of the Company or its transfer agent as are necessary to pay the purchase price
in accordance with the provisions herein;

 

(E) If any such transfer of
outstanding shares requires the consent of any governmental agency under the securities laws of any state, or an opinion of counsel for
the Company or Optionee that such transfer may be effected under applicable Federal and state securities laws, the time periods specified
herein shall be extended for such periods as the necessary request for consent to transfer is pending before said Commission or other
agency, or until counsel renders such an opinion, as the case may be. All parties agree to cooperate in making such request for transfer,
or in obtaining such opinion of counsel, and no transfer shall be effected without such consent or opinion if required by law; and

 

(F) Notwithstanding any other
provision herein, Optionee shall be permitted to pay the purchase price only with shares of the Company’s Common Stock owned by
him as of the exercise date and only in the manner and within the time periods allowed under 17 CFR § 240.16b-3 promulgated under
the Securities Exchange Act of 1934 as such regulation is presently constituted, as it is amended from time to time, and as it is interpreted
now or hereafter by the Securities and Exchange Commission.

 

(d) Agreement
to Execute Other Agreements. Optionee agrees to execute, as a condition precedent to the exercise of the Option and at any time
thereafter as may reasonably be requested by the Board, any and all agreements that may be common among some or all of the
Company’s stockholders, including, without limitation, a stockholders agreement and a voting agreement (collectively, the
“Stockholders Agreements”), with respect to any shares Optionee acquired pursuant to this Agreement, provided,
however, that execution of such Stockholders Agreements will not be required upon any exercise that occurs after the closing of
the first public offering of capital stock of the Company that is effected pursuant to a registration statement filed with, and
declared effective by, the Securities and Exchange Commission under the Securities Act or, if later, the expiration of any market
stand-off agreement that applies to other stockholders of the Company with respect to such public offering of capital stock.

 

    -3-

     

    

 

3. Term and Expiration.
This Option, if it has not earlier expired pursuant to the terms of this Agreement or the Plan, shall expire in all events on the tenth
(10th) anniversary of the Date of Grant set forth on the first page hereof.

 

4. Compliance with State
and Federal Securities Laws. No Shares shall be issued upon the exercise of this Option unless and until the Company has determined
that all applicable provisions of state and Federal securities laws have been satisfied.

 

5. Adjustment Upon Changes
in Capitalization or Merger. The number of Shares covered by this Option shall be adjusted in accordance with the provisions of Section
11 of the Plan in the event of changes in the capitalization or organization of the Company, or if the Company is a party to a merger
or other corporate reorganization.

 

6. Not Employment Contract.
Nothing in this Agreement or in the Plan shall confer upon Optionee any right to continue in the employ of or as a service provider to
the Company (or of any Parent of the Company, any Subsidiary of the Company, or any Subsidiary of any Parent of the Company) or shall
interfere with or restrict in any way the rights of the Company (or of any Parent of the Company, any Subsidiary of the Company, or any
Subsidiary of any Parent of the Company), which are hereby expressly reserved, to discharge Optionee at any time for any reason whatsoever,
with or without cause, subject to the provisions of applicable law. This is not an employment or service provider contract.

 

7. Income Tax Withholding.
Optionee authorizes the Company to report income and to withhold in accordance with applicable law from any compensation payable to him
or her any and all taxes required to be withheld by Federal, state, local and/or foreign laws as a result of the exercise of this Option
and further agrees that the Company and the Company’s agents shall not be required to deliver any shares purchased by Optionee upon
exercise of this Option unless and until Optionee’s tax obligations have been satisfied to the Company’s satisfaction or Optionee
has provided the Company with such payments. Optionee understands and agrees that the Company may require Optionee to make a cash payment
to cover any withholding tax obligations as a condition of exercise of the Option. Furthermore, in the event of any determination that
the Company has failed to withhold a sum sufficient to pay all withholding taxes due in connection with the exercise of this Option, Optionee
agrees to pay the Company the amount of any such deficiency in cash within five (5) days after receiving a written demand from the Company
to do so, whether or not Optionee is an Employee or service provider of the Company at that time. In addition, to ensure compliance with
applicable state corporate law, the Company may require Optionee to furnish consideration in the form of cash or cash equivalents equal
to the par value of the Shares issued upon exercise of this Option, and Optionee hereby authorizes the Company to withhold such amount
from remuneration otherwise due Optionee from the Company.

 

    -4-

     

    

 

8. Market Stand-Off
Agreement. Optionee agrees that following the effective date of a registration statement of the Company filed under the
Securities Act, Optionee, for the duration specified by and to the extent requested by the Company and an underwriter of Common
Stock or other securities of the Company, shall not offer, sell, contract to sell, pledge or otherwise dispose of, directly or
indirectly, any equity securities of the Company, or any securities convertible into or exchangeable or exercisable for such
securities, enter into a transaction which would have the same effect, or enter into any swap, hedge or other arrangement that
transfers, in whole or in part, any of the economic consequences of ownership of such securities, whether any such aforementioned
transaction is to be settled by delivery of such securities or other securities, in cash or otherwise, or publicly disclose the
intention to make any such offer, sale, pledge or disposition, or to enter into any such transaction, swap, hedge or other
arrangement, in each case during the seven (7) days prior to and the one hundred eighty (180) days after the effectiveness of any
underwritten offering of the Company’s equity securities (or such longer or shorter period as may be requested in writing by
the managing underwriter and agreed to in writing by the Company) (the “Market Stand-Off Period”), except
as part of such underwritten registration if otherwise permitted. In addition, Optionee agrees to execute any further letters,
agreements and/or other documents requested by the Company or its underwriters that are consistent with the terms of this Section 8.
The Company may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of

Seller’s principal place of business is located at the address set forth in the Recitals of this Agreement.

 

Section

representatives) that, other than the representations and warranties of the Seller expressly made in Article 4, there are no representations
or warranties of the Seller or any other Person either expressed, statutory, or implied with respect to the Transferred Assets or the

the place they are located on the Effective Date based on its own inspection, examination, and determination with respect to all matters,
and without reliance upon any express or implied representations or warranties of any nature made by, on behalf of, or imputed to the
Seller. Without limiting the generality of the foregoing, the Purchaser acknowledges that the Seller makes no representation or warranty
with respect to: (i) any forecasts, projections, estimates, or budgets delivered or made available to the Purchaser of future revenues,
future results of operations (or any component thereof), future cash flows, or future financial condition (or any component thereof)
of the Transferred Assets; or (ii) any other information or documents made available to the Purchaser or its counsel, accountants or

    24

     

    

 

Section
8.3 Indemnification Procedures. In the event that any Person entitled to indemnification under Section 8.1 or Section
8.2 (an “Indemnified Party”) is seeking indemnification, the Indemnified Party shall (a) inform, in writing,
the indemnifying Party under Section 8.1 or Section 8.2 (the “Indemnifying Party”) as soon as
reasonably practicable after the Indemnified Party receives any written notice of any Action against or involving the Indemnified
Party by a Governmental Authority or other Person, or otherwise discovers the Liability, obligation or facts giving rise to such
claim for indemnification (the “Claim”), (b) permit the Indemnifying Party to assume direction and control of the
defense of the Claim (provided, that the Indemnifying Party may not enter into a settlement of the Claim that would adversely
affect the Indemnified Party’s rights hereunder, or impose any obligations on the Indemnified Party in addition to those set
forth in the Transaction Documents, without the prior consent of the Indemnified Party, not to be unreasonably withheld), (c)
cooperate as reasonably requested (at the expense of the Indemnifying Party) in the defense of the Claim and
(d) undertake all reasonable steps to mitigate any loss, damage or expense with respect to
the Claim(s). Without limiting the foregoing, any Indemnified Party will be entitled to participate in the defense of a Claim for
which it has sought indemnification hereunder and to employ counsel of its choice for such purpose; provided, that such
employment will be at the Indemnified Party’s own expense unless (i) the employment thereof has been specifically authorized
by the Indemnifying Party in writing or (ii) the Indemnifying Party has failed to assume the defense (or has failed to continue to
defend such Claim in good faith) and employ counsel in accordance with this Section 8.3, in which case the indemnified Party
will be allowed to control the defense.

 

Section
8.4 Survival. The representations and warranties of the Parties contained herein shall survive for a period of twelve (12) months
following the Closing, except that (a) each of the Seller’s and the Purchaser’s Fundamental Representations shall survive
indefinitely and (b) the representations and warranties of the Seller set forth in Section 4.11 shall survive for the longer of
twelve (12) months or the statutory period. Any claim for indemnification on account of breach of a representation, warranty or covenant
will survive the applicable termination date if a Party, prior to such termination date, advises the other Party in writing of facts
that constitute or may give rise to an alleged claim for indemnification, specifying in reasonable detail the basis under this Agreement
for such claim.

 

Section
8.5 Insurance Proceeds. The amount of any Losses required to be reimbursed under this Article 8 sustained by an Indemnified
Party shall be reduced by any amount received by such Indemnified Party with respect thereto under any insurance coverage or from any
other Person alleged to be responsible therefore (net of any expenses incurred in recovering such monies, any deductible and any increase
in premiums as a result of such claim); provided, the amount of such reduction shall not exceed the amount of such Losses; provided,
further, the Indemnified Party shall be entitled to seek indemnification pursuant to this Article 8 for the amount of such
Losses net of the amount of such reductions (net of any expenses incurred in recovering such monies, any deductible and any increase
in premiums as a result of such claim). The Indemnified Parties shall use commercially reasonable efforts to collect any amounts available
under such insurance coverage and from such other Person alleged to have responsibility. If an Indemnified Party receives an amount under
insurance coverage or from such other Person with respect to Losses sustained at any time subsequent to any indemnification payment pursuant
to this Article 8, then such Indemnified Party shall promptly reimburse the applicable Indemnifying Party for any payment made
or expense incurred by such Indemnifying Party in connection with providing such indemnification up to such amount received by the Indemnified
Party.

 

    25

     

    

 

Section
8.6 Duty to Mitigate. Each Indemnified Party shall be obligated to use its commercially reasonable efforts to mitigate to the
fullest extent reasonably practicable the amount of any Losses for which it is entitled to seek indemnification under this Article
8, and the Indemnifying Party shall not be required to make any payment to an Indemnified Party in respect of such Losses to the
extent such Losses arise from the failure of the Indemnified Party to comply with the foregoing obligation. All reasonable costs and
expenses incurred in connection with such mitigation shall be included as indemnifiable Losses to the extent reasonably incurred in an
effort to mitigate an indemnifiable Loss.

 

Section
8.7 Limitation of Liability. EXCEPT FOR A BREACH OF ARTICLE 7, A PARTY’S INDEMNIFICATION OBLIGATIONS UNDER SECTION
8.1 OR 8.2, OR FOR ACTS OF GROSS NEGLIGENCE OR WRONGFUL INTENTIONAL ACTS OR OMISSIONS, (A) NEITHER
PARTY, NOR ANY OF THEIR AFFILIATES SHALL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES FOR ANY INDIRECT, CONSEQUENTIAL, SPECIAL, RELIANCE OR PUNITIVE DAMAGES, WHETHER
LIABILITY IS ASSERTED IN CONTRACT OR TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), AND IRRESPECTIVE OF WHETHER THAT PARTY
OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE,
AND (B) THE ENTIRE LIABILITY OF EITHER PARTY TO THE OTHER IN CONNECTION WITH THIS AGREEMENT SHALL NOT EXCEED,
IN THE AGGREGATE, ALL OF THE AMOUNTS PAID OR PAYABLE BY THE PURCHASER TO THE SELLER (INCLUDING THE FAIR MARKET VALUE OF ANY EQUITY OF
THE PURCHASER ISSUED TO THE SELLER UNDER SECTION 3.1) UNDER THE TRANSACTION DOCUMENTS AS OF THE DATE OF THE ALLEGED BREACH.

 

Section
8.8 Remedies.

 

(a) Notwithstanding
anything to the contrary contained in the foregoing, nothing herein shall (i) limit the liability of any Party for gross negligence or
wrongful intentional acts or (ii) prevent any Party from seeking the remedies of specific performance or injunctive relief in connection
with a breach of a covenant or agreement of any Party contained herein, except as otherwise provided herein.

 

(b) Except
as otherwise provided herein, any and all remedies herein expressly conferred upon a Party will be deemed cumulative with and not exclusive
of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude
the exercise of any other remedy. The Parties agree that irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were otherwise breached. The Parties accordingly agree that they
shall be entitled to seek a temporary injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the
performance of the terms and provisions hereof in any court in the State of New York, in addition to any other remedy to which they are
entitled at Law or in equity.

Section
9.1 Governing Law. This Agreement and all disputes arising out of or related to this Agreement or any breach hereof shall be
governed by and construed under the laws of the State of New York, without giving effect to any choice of law principles that would

Section
9.2 Dispute Resolution. Except for any claims or disputes arising out of or relating to Article 7 of this Agreement (which
may be brought in any court of competent jurisdiction immediately), any claim or dispute arising out of or under this Agreement shall
be resolved through binding arbitration before JAMS, Inc. (“JAMS”), unless the Parties agree otherwise. Except as
provided in this Agreement, arbitration shall be the exclusive means for resolution of such claim or dispute. The Streamlined Arbitration
Rules & Procedures of JAMS in effect at the time the arbitration is initiated shall apply. The arbitration shall be before a single
arbitrator, who: (a) is a lawyer of not less than fifteen (15) years’ standing who is knowledgeable in the law concerning the subject
matter at issue in the dispute, (b) is not, and have never been, an employee, consultant, officer, director or stockholder of either
Party or of any Affiliate of either Party, and (c) does not have a conflict of interest under any applicable rules of ethics. The place

the arbitration reward is rendered or the controversy is otherwise resolved. The arbitrator shall have no authority to award punitive
or any other type of damages not measured by a Party’s compensatory damages. Each Party shall pay for its own attorneys’
fees, costs and expenses incurred in connection with the arbitration. The decision of the arbitrator shall be final and binding, and
such decision may be confirmed in any court having competent jurisdiction.

 

Section
9.3 Force Majeure. Neither Party shall be liable for failure of or delay in performing obligations set forth in this Agreement,
and neither shall be deemed in breach of its obligations, if such failure or delay is due to any occurrence beyond the reasonable control
of such Party that (a) prevents or substantially interferes with the performance by such Party of any of its obligations hereunder and
(b) occurs by reason of any act of God, flood, fire, explosion, earthquake, strike, lockout, labor dispute, casualty or accident, war,
revolution, civil commotion, act of terrorism, blockage or embargo, or injunction, law, order, proclamation, regulation, ordinance, demand
or requirement of any government or of any subdivision, authority or representative of any such government. In event of such force majeure,
the Party affected shall use reasonable efforts to cure or overcome the same and resume performance of its obligations hereunder.

 

Section
9.4 Assignment. This Agreement may not be assigned by either Party to any other Person, including as a result of a Change of Control
or by operation of law, without the prior written consent of the other Party, which consent shall not be unreasonably withheld. Any permitted
assignee will expressly assume, in writing, all obligations imposed on the assigning Party by this Agreement, including Sections 3.1
and 3.2. This Agreement shall bind and inure to the benefit of the Parties hereto and their respective permitted assigns.
Any purported assignment in violation of this Section 9.4 shall be null and void.

 

    27

     

    

 

Section
9.5 Severability. If any provision hereof should be held invalid, illegal or unenforceable in any jurisdiction, the Parties shall
negotiate in good faith a valid, legal and enforceable substitute provision that most nearly reflects the original intent of the Parties
and all other provisions hereof shall remain in full force and effect in such jurisdiction and shall be liberally construed in order
to carry out the intentions of the Parties hereto as nearly as may be possible. Such invalidity, illegality or unenforceability shall
not affect the validity, legality or enforceability of such provision in any other jurisdiction.

Section

have been or may from time to time hereafter be amended, restated, modified, supplemented, or re-enacted. The Exhibits and other attachments
form part of the operative provisions of this Agreement and references to this Agreement shall, unless the context otherwise requires,
include references to the recitals and the Exhibits and attachments.

 

Section
9.9 Independent Contractors. Nothing herein shall be construed to create any relationship of employer and employee, agent and
principal, partnership, or joint venture between the Parties. Each Party is an independent contractor. Neither Party shall assume, either
directly or indirectly, any liability of or for the other Party. The Parties shall not have the authority to bind or obligate the other
Party and neither Party shall represent that it has such authority.

 

Section
9.10 Performance by Affiliates. Each Party may discharge any obligations and exercise any right hereunder through any of its Affiliates.
Each Party hereby guarantees the performance by its Affiliates of such Party’s obligations under this Agreement, and shall cause
its Affiliates to comply with the provisions of this Agreement in connection with such performance. Any breach by a Party’s Affiliate
of any of such Party’s obligations under this Agreement shall be deemed a breach by such Party, and the other Party may proceed
directly against such Party without any obligation to first proceed against such Party’s Affiliate.

 

Section
9.11 Waiver. Neither Party may waive or release any of its rights or interests in this Agreement except in writing. The failure
of either Party to assert a right hereunder or to insist upon compliance with any term or condition of this Agreement shall not constitute
a waiver of that right or excuse a similar subsequent failure to perform any such term or condition. No waiver by either Party of any
condition or term in any one or more instances shall be construed as a continuing waiver of such condition or term or of another condition
or term.

 

Section
9.12 Counterparts. This Agreement may be signed in counterparts, each and every one of which shall be deemed an original, notwithstanding
variations in format or file designation which may result from the electronic transmission, storage and printing of copies of this Agreement
from separate computers or printers. Signatures transmitted via .pdf shall be treated as original signatures.

and preparation of this Agreement and, except as set forth in this Agreement, the performance of the obligations contemplated hereby
and thereby.

sets forth the complete, final and exclusive agreement and all the covenants, promises, agreements, warranties, representations, conditions
and understandings between the Parties with respect to the subject matter hereof and supersedes, as of the Closing Date, all prior and

the Patent Rights (including rights resulting from any post-grant proceedings relating to any of the foregoing for all jurisdictions
throughout the world), and (h) all rights under the Paris Convention for the Protection of Industrial Property, all to be held and
enjoyed by Assignee, its successors and assigns, as fully and entirely as the same would have been held and enjoyed by Assignor had
this Assignment not been made.

 

     

     

    

 

3. Recordation.
From and after the date hereof, Assignee shall be responsible for and shall pay all costs relating to the registration, maintenance and
prosecution of the Patent Rights, including payment of any associated fees therefor, for the notarization, authentication, legalization
or consularization of Assignee’s signatures hereof, and for the recording of such assignment documents with the appropriate Governmental
Authorities. Assignor hereby authorizes the applicable patent offices or other relevant Governmental Authority to register and record
Assignee as the assignee and owner of the Patent Rights, including any issuances, reissuances, continuations, divisions, continuations-in
part, revisions, renewals, extensions and reexaminations with respect thereto.

 

4. No
Warranty. For the sake of clarity and as part of this Assignment, Assignor makes no representations or warranties, either express
or implied, as the adequacy or sufficiency of the Patent Rights, their freedom from defects of any kind, including freedom from any claim
of patent or trade secret infringement and may result from the use thereof. This Assignment provides no warranties, including warranties
of title.

 

5. Further
Assurances. Assignor further agrees that Assignor will, without demanding any further consideration therefor, at the request but
at the expense of Assignee, do all lawful and just acts, including without limitation the execution and acknowledgment of instruments
that may be or become necessary to effect or formalize the transfer of the Patent Rights or as may be necessary to prosecute, obtain,
maintain or enforce the Patent Rights.

 

6. Miscellaneous.
This Assignment is executed and delivered pursuant to, and is given to further evidence (and give immediate effect to) the transfers
and assignments contemplated by the Purchase Agreement upon the terms and conditions specified therein. In the event that any provision
of this Assignment shall be construed to conflict with a provision in the Purchase Agreement, the provision in the Purchase Agreement
shall control. This Assignment may be executed in counterparts, each of which shall be deemed to be an original, and all of which shall
be deemed to constitute the same agreement. If any signature is delivered by facsimile transmission or by email in PDF, such signature
shall create a valid and binding obligation of the Party executing (or on whose behalf the signature is executed) with the same force
and effect as if such facsimile or PDF signature were an original thereof. This Assignment shall be binding upon and shall inure to the
benefit of the Parties and their respective successors and assigns. This Assignment and the rights and obligations of the Parties shall
be construed in accordance with and governed by the laws of the State of New York, without regard to its conflict of laws principles,
and shall be subject to the provisions of Section 9.2 (Dispute Resolution) of the Purchase Agreement.
