from the Company, and Company hereby sells to Purchaser, an aggregate of 164,108 (one hundred sixty thousand one hundred and eight) shares

per Share (the “Purchase Price Per Share”). As used in this Agreement, the term “Shares”
refers to the Shares purchased under this Agreement and includes all securities received (a) in substitution of the Shares, (b) as
a result of stock dividends or stock splits with respect to the Shares, and (c) in replacement of the Shares in a merger, recapitalization,
reorganization or similar corporate transaction.


 


2. PAYMENT

2.1 Deliveries
by Purchaser. Purchaser hereby delivers to the Company: (a) a duly executed copy of this Agreement, (b) two (2) copies of a blank
Stock Power and Assignment Separate from Stock Certificate in the form of Exhibit 1 attached hereto (the “Stock
Powers”), both executed by Purchaser (and Purchaser’s spouse, if any), (c) if Purchaser is married, a Spouse Consent
in the form of Exhibit 2 attached hereto (the “Spouse Consent”) duly executed by Purchaser’s
spouse, and (d) payment of the Purchase Price by delivery to the Company of a check in the amount of the Purchase Price a copy of which

2.2 Deliveries
by the Company. Upon its receipt of the entire Purchase Price and all the documents to be executed and delivered by Purchaser
to the Company under Section 2.1, the Company will issue a duly executed stock certificate evidencing the Shares in the name of Purchaser,
registered in Purchaser’s name, with such certificate to be placed in escrow as provided in Section 8 until expiration or termination
of both the Company’s Right of First Refusal and Repurchase Option as described in Sections 5 and 6.


 


3. REPRESENTATIONS
AND WARRANTIES OF PURCHASER. Purchaser hereby represents and warrants to the Company as follows.


 


3.1 Purchase
for Own Account for Investment. Purchaser is purchasing the Shares for Purchaser’s own account for investment purposes only
and not with a view to, or for sale in connection with, a distribution of the Shares within the meaning of the Securities Act of 1933,
as amended (the “1933 Act”). Purchaser has no present intention of selling or otherwise disposing of all or
any portion of the Shares and no one other than Purchaser has any beneficial ownership of any of the Shares.


 


3.2 Access
to Information. Purchaser has had access to all information regarding the Company and its present and prospective business, assets,
liabilities and financial condition that Purchaser reasonably considers important in making the decision to purchase the Shares, and Purchaser
has had ample opportunity to ask questions of the Company’s representatives concerning such matters and this investment.


 






     


     


    

 


3.3 Understanding
of Risks. Purchaser is fully aware of: (a) the highly speculative nature of the investment in the Shares; (b) the financial hazards
involved; (c) the lack of liquidity of the Shares and the restrictions on transferability of the Shares (e.g., that Purchaser may
not be able to sell or dispose of the Shares or use them as collateral for loans); (d) the qualifications and backgrounds of the management
of the Company; and (e) the tax consequences of investment in the Shares.


 


3.4 Purchaser’s
Qualifications. Purchaser has a preexisting personal or business relationship with the Company and/or certain of its officers
and/or directors of a nature and duration sufficient to make Purchaser aware of the character, business acumen and general business and
financial circumstances of the Company and/or such officers and directors. By reason of Purchaser’s business or financial experience,
Purchaser is capable of evaluating the merits and risks of this investment, has the ability to protect Purchaser’s own interests
in this transaction and is financially capable of bearing a total loss of this investment.


 


3.5 No
General Solicitation. At no time was Purchaser presented with or solicited by any publicly issued or circulated newspaper, mail,
radio, television or other form of general advertising or solicitation in connection with the offer, sale and purchase of the Shares.


 


3.6 Compliance
with Securities Laws. Purchaser understands and acknowledges that, in reliance upon the representations and warranties made by
Purchaser herein, the Shares are not being registered with the Securities and Exchange Commission (“SEC”)
under the 1933 Act or being qualified under applicable state securities laws, but instead are being issued under an exemption or exemptions
from the registration and qualification requirements of the 1933 Act and applicable state securities laws which impose certain restrictions
on Purchaser’s ability to transfer the Shares.


 


3.7 Restrictions
on Transfer. Purchaser understands that Purchaser may not transfer any Shares unless such Shares are registered under the 1933
Act and qualified under applicable state securities laws or unless, in the opinion of counsel to the Company, exemptions from such registration
and qualification requirements are available. Purchaser understands that only the Company may file a registration statement with the SEC
or applicable state securities commissioners and that the Company is under no obligation to do so with respect to the Shares. Purchaser
has also been advised that exemptions from registration and qualification may not be available or may not permit Purchaser to transfer
all or any of the Shares in the amounts or at the times proposed by Purchaser.


 


3.8 Rule 144.
In addition, Purchaser has been advised that SEC Rule 144 promulgated under the 1933 Act, which permits certain limited sales of
unregistered securities, is not presently available with respect to the Shares and, in any event, requires that the Shares be held for
a minimum of six months, and in certain cases one year, after they have been purchased and paid for (within the meaning of Rule 144),
before they may be resold under Rule 144. Purchaser understands that Rule 144 may indefinitely restrict transfer of the Shares
so long as Purchaser remains an “affiliate” of the Company and certain information about the Company (as defined in Rule 144)
is not publicly available.


 






    2


     


    

 


4. MARKET
STANDOFF AGREEMENT. Purchaser agrees in connection with any registration of the Company’s securities under
the 1933 Act that, upon the request of the Company or the underwriters managing any registered public offering of the Company’s
securities, Purchaser will not sell or otherwise dispose of any Shares without the prior written consent of the Company or such underwriters,
as the case may be, for such period of time (not to exceed one hundred eighty (180) days) after the effective date of such registration
requested by such managing underwriters and subject to all restrictions as the Company or the managing underwriters may specify for employee-shareholders
generally. For purposes of this Section 4, the term “Company” shall include any wholly owned subsidiary of the Company into
which the Company merges or consolidates. In order to enforce the foregoing covenant, the Company shall have the right to place restrictive
legends on the certificates representing the Shares subject to this Section and to impose stop transfer instructions with respect to the
Shares until the end of such period. Purchaser further agrees to enter into any agreement reasonably required by the underwriters to implement
the foregoing and that such underwriters are express third party beneficiaries of this Section 4.


 


5. RIGHT
OF FIRST REFUSAL. Unvested Shares (defined in Section 6.2 below) may not be sold or otherwise transferred by Purchaser
without the Company’s prior written consent. Before any Vested Shares (defined in Section 6.2 below) held by Purchaser or any transferee
of such Vested Shares (either sometimes referred to herein as the “Holder”) may be sold or otherwise transferred
(including without limitation a transfer by gift or operation of law), the Company and/or its assignee(s) will have a right of first refusal
to purchase the Shares to be sold or transferred (the “Offered Shares”) on the terms and conditions set forth
in this Section (the “Right of First Refusal”).


 


5.1 Notice
of Proposed Transfer. The Holder of the Offered Shares will deliver to the Company a written notice (the “Notice”)
stating: (a) the Holder’s bona fide intention to sell or otherwise transfer the Offered Shares; (b) the name and address
of each proposed purchaser or other transferee (the “Proposed Transferee”); (c) the number of Offered Shares
to be transferred to each Proposed Transferee; (d) the bona fide cash price or other consideration for which the Holder proposes
to transfer the Offered Shares (the “Offered Price”); and (e) that the Holder acknowledges this Notice
is an offer to sell the Offered Shares to the Company and/or its assignee(s) pursuant to the Company’s Right of First Refusal at
the Offered Price as provided for in this Agreement.


 


5.2 Exercise
of Right of First Refusal. At any time within thirty (30) days after the date the Notice was effective in accordance with Section
12.1 hereof, the Company and/or its assignee(s) may, by giving written notice to the Holder, elect to purchase all (or, with the consent
of the Holder, less than all) the Offered Shares proposed to be transferred to any one or more of the Proposed Transferees named in the
Notice, at the purchase price determined in accordance with Section 5.3 below.


 


5.3 Purchase
Price. The purchase price for the Offered Shares purchased under this Section will be the Offered Price, provided that if the
Offered Price consists of no legal consideration (as, for example, in the case of a transfer by gift), the purchase price will be the
fair market value of the Offered Shares as determined in good faith by the Company’s Board of Directors. If the Offered Price includes
consideration other than cash, then the value of the non-cash consideration, as determined in good faith by the Company’s Board
of Directors, will conclusively be deemed to be the cash equivalent value of such non-cash consideration.


 






    3


     


    

 


5.4 Payment.
Payment of the purchase price for the Offered Shares will be payable, at the option of the Company and/or its assignee(s) (as applicable),
by check or by cancellation of all or a portion of any outstanding indebtedness owed by the Holder to the Company (or to such assignee,
in the case of a purchase of Offered Shares by such assignee) or by any combination thereof. The purchase price will be paid without interest
within sixty (60) days after the Company’s receipt of the Notice, or, at the option of the Company and/or its assignee(s), in the
manner and at the time(s) set forth in the Notice.


 


5.5 Holder’s
Right to Transfer. If all of the Offered Shares proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section, then the Holder may sell or otherwise transfer such Offered
Shares to each Proposed Transferee at the Offered Price or at a higher price, provided that (a) such sale or other transfer
is consummated within one hundred twenty (120) days after the date of the Notice, (b) any such sale or other transfer is effected
in compliance with all applicable securities laws, and (c) each Proposed Transferee agrees in writing that the provisions of this
Section will continue to apply to the Offered Shares in the hands of such Proposed Transferee. If the Offered Shares described in the
Notice are not transferred to each Proposed Transferee within such one hundred twenty (120) day period, then a new Notice must be given
to the Company, pursuant to which the Company will again be offered the Right of First Refusal before any Shares held by the Holder may
be sold or otherwise transferred.


 


5.6 Exempt
Transfers. Notwithstanding anything to the contrary in this Section, the following transfers of Vested Shares will be exempt from
the Right of First Refusal: (a) the transfer of any or all of the Vested Shares during Purchaser’s lifetime by gift or on Purchaser’s
death by will or intestacy to Purchaser’s “Immediate Family” (as defined below) or to a trust for the benefit of Purchaser
or Purchaser’s Immediate Family, provided that each transferee or other recipient agrees in a writing satisfactory to the Company
that the provisions of this Section will continue to apply to the transferred Vested Shares in the hands of such transferee or other recipient;
(b) except as provided in Section 5.7 clause (b) below, any transfer or conversion of Vested Shares made pursuant to a statutory
merger or statutory consolidation of the Company with or into another corporation or corporations; or (c) any transfer of Vested
Shares pursuant to the winding up and dissolution of the Company. As used herein, the term “Immediate Family”
will mean Purchaser’s spouse or Spousal Equivalent, the lineal descendant or antecedent, brother or sister, of Purchaser or Purchaser’s
spouse or Spousal Equivalent, or the spouse or Spousal Equivalent, of any lineal descendant or antecedent, brother or sister of Purchaser,
or Purchaser’s spouse or Spousal Equivalent, whether or not any of the above are adopted. As used herein, a person is deemed to
be a “Spousal Equivalent” if the relevant person and the related party are registered as “domestic partners”
under the laws of the State of New York or any other law having similar effect or provided the following circumstances are true: (a) irrespective
of whether or not the relevant person and the Spousal Equivalent are the same sex, they are the sole spousal equivalent of the other for
the last twelve (12) months, (b) they intend to remain so indefinitely, (c) neither are married to anyone else, (d) both
are at least eighteen (18) years of age and mentally competent to consent to contract, (e) they are not related by blood to a degree
of closeness that which would prohibit legal marriage in the state in which they legally reside, (f) they are jointly responsible
for each other’s common welfare and financial obligations, and (g) they reside together in the same residence for the last
twelve (12) months and intend to do so indefinitely.


 






    4


     


    

 


5.7 Termination
of Right of First Refusal. The Right of First Refusal will terminate as to all Shares (a) on the effective date of the first sale
of Common Stock of the Company to the general public pursuant to a registration statement filed with and declared effective by the SEC
under the 1933 Act (other than a registration statement relating solely to the issuance of Common Stock pursuant to a business combination
or an employee incentive or benefit plan) or (b) on any transfer or conversion of Shares made pursuant to a statutory merger or statutory
consolidation of the Company with or into another corporation or corporations if the common stock of the surviving corporation or any
direct or indirect parent corporation thereof is registered under the Securities Exchange Act of 1934, as amended.


 


6. COMPANY’S
REPURCHASE OPTION. The Company and/or its assignees shall have the option to repurchase all or a portion of the
Unvested Shares (defined in Section 6.2 below) on the terms and conditions set forth in this Section (the “Repurchase Option”)
if Purchaser ceases to be employed (as defined herein) by the Company for any reason, or no reason, including without limitation Purchaser’s
death, disability, voluntary resignation or termination by the Company with or without cause.


 


6.1 Definition
of “Employed by the Company”; “Termination Date”. For purposes of this Agreement, Purchaser will be considered
to be “employed by the Company” if the Board of Directors of the Company (the “Board”) determines
that Purchaser is rendering services as an officer, employee, advisor, consultant or independent contractor to the Company or to any Affiliate
of the Company. In case of any dispute as to whether Purchaser is employed by the Company, the Board shall have sole discretion to determine
whether Purchaser has ceased to be employed by the Company or any Affiliate and the effective date on which Purchaser’s employment
terminated (the “Termination Date”). An “Affiliate” means any entity that owns, directly
or indirectly, stock representing more than fifty percent (50%) of the total combined voting power of all classes of stock of the Company
or any entity in which the Company owns, directly or indirectly, equity interests representing more than fifty percent (50%) of the voting
power of such entity.


 


6.2 Unvested
and Vested Shares.


 


6.2.1 Vesting
Schedule. Shares that are vested pursuant to the schedule set forth herein are “Vested Shares”. Shares that
are not vested pursuant to the schedule set forth herein are “Unvested Shares.” Unvested Shares may not be sold
or otherwise transferred by Purchaser without the Company’s prior written consent. On the Effective Date all of the Shares are Unvested
Shares. If Purchaser has continuously been employed by the Company or any Affiliate at all times from the Effective Date until June 30
(the “First Vesting Date”), then on the First Vesting Date 1/24th of the Unvested Shares will become
Vested Shares; and thereafter, for so long (and only for so long) as Purchaser remains continuously employed by the Company or any Affiliate
or successor (referred to collectively with the Company in this Section 6.2 as the “Company”) at all times after
the First Vesting Date, on the last day of each succeeding calendar month after the First Vesting Date, an additional 1/24th of the Unvested
Shares will become Vested Shares. No Unvested Shares will become Vested Shares after the Termination Date. If the application of the vesting
percentage results in a fractional share, such share shall be rounded down to the nearest whole share for each month except for the last
month in such vesting period, at the end of which last month the balance of Unvested Shares shall become fully Vested Shares.


 






    5


     


    

 


6.2.2 Acceleration of
Vesting Following Change of Control and Termination. In addition to any Shares that have become Vested Shares pursuant to Section
6.2.1 hereof, if there is a Change of Control while Purchaser is still employed by the Company 100% of the Shares that are Unvested Shares
as of the closing of the Change of Control will become Vested Shares at the time of or immediately before such closing. “Change
of Control” means (a) any transaction or series of related transactions resulting in a liquidation, dissolution or winding
up of the Company, (b) a sale of all or substantially all of the assets of the Company that is followed by a liquidation, dissolution
or winding up of the Company, (c) any sale or exchange of the capital stock of the Company by the stockholders of the Company in one
transaction or a series of related transactions where more than fifty percent (50%) of the outstanding voting power of the Company is
acquired by a person or entity or group of related persons or entities (other than pursuant to a recapitalization of the Company solely
with its equity holders) or (d) any merger or consolidation (each, a “combination transaction”), in which the
Company is a constituent entity or is a party with another entity if, as a result of such combination transaction, in one transaction
or series of related transactions, the voting securities of the Company that are outstanding immediately prior to the consummation of
such combination transaction (other than any such securities that are held by an “Acquiring Stockholder,” as defined
below) do not represent, or are not converted into, securities of the surviving entity in such combination transaction (or such surviving
entity’s parent entity if the surviving entity is owned by the parent) that, immediately after the consummation of such combination
transaction, together possess at least a majority of the total voting power of all voting securities of such surviving entity (or its
parent, if applicable) that are outstanding immediately after the consummation of such combination transaction, including securities
of such surviving entity (or its parent, if applicable) that are held by the Acquiring Stockholder; provided, however, that the
Merger described in that non-binding Term Sheet dated April 5, 2021 to which the Company and Montrose Capital Partners Limited are parties
shall not be a Change of Control under this Section 6.2.2 and no acceleration of vesting of Shares shall occur in connection with
the closing of such Merger notwithstanding that the Merger might otherwise qualify as a Change of Control under the definition set forth
in clauses (a) through (d) of this Section 6.2.2. For purposes of this paragraph, an “Acquiring Stockholder”
means a stockholder or stockholders of the Company that (i) merges or combines with the Company in such combination transaction or (ii)
directly or indirectly owns or controls a majority of the voting power of another entity that merges or combines with the Company
in such combination transaction.


 


6.3 Adjustments.
The number of Shares that are Vested Shares or Unvested Shares will be proportionally adjusted to reflect any stock dividend, stock split,
reverse stock split or recapitalization of the common stock of the Company occurring after the Effective Date.


 


6.4 Exercise
of Repurchase Option at Original Price. At any time within ninety (90) days after the Termination Date, the Company may elect
to repurchase any or all of the Unvested Shares by giving Purchaser written notice of exercise of the Repurchase Option. The Company and/or
its assignee(s) will then have the option to repurchase from Purchaser (or from Purchaser’s personal representative as the case
may be) any or all of the Unvested Shares at the Purchase Price Per Share specified in Section 1 above, as adjusted to reflect any
stock dividend, stock split, reverse stock split or recapitalization of the common stock of the Company occurring after the Effective
Date (the “Repurchase Price”). Notwithstanding anything to the contrary in the foregoing, unless the Company
notifies the Purchaser within ninety (90) days from the Termination Date that it does not intend to exercise its Repurchase Option with
respect to some or all of the Unvested Shares, the Repurchase Option shall be deemed automatically exercised by the Company at the end
of such ninety (90) day period from the Termination Date and the execution of this Agreement shall constitute deemed notice of the Company’s
intention to exercise its Repurchase Option with respect to all Unvested Shares to which its Repurchase Option applies (the “Deemed
Notice”). If the Company neither notifies Purchaser prior to the end of such ninety (90) day period of the Company’s
decision not to exercise its Repurchase Option, nor delivers payment of the aggregate Repurchase Price to Purchaser after the actual or
deemed exercise of the Repurchase Option, then the sole remedy of Purchaser thereafter shall be to receive the aggregate Repurchase Price
from the Company in the manner set forth above for the Unvested Shares that are deemed repurchased, and in no case shall Purchaser have
any claim of ownership as to any of such Unvested Shares.


 






    6


     


    

 


6.5 Payment
of Repurchase Price. The Repurchase Price will be payable, at the option of the Company and/or its assignee(s), as the case may
be, by check or by cancellation of all or a portion of any outstanding indebtedness owed by Purchaser to the Company (or to such assignee)
or by any combination thereof. The Repurchase Price will be paid without interest within ninety (90) days after the Company gives the
Purchaser written notice of the exercise of its Repurchase Option or the effectiveness of the Deemed Notice.


 


6.6 Right
of Termination Unaffected. Nothing in this Agreement will be construed to limit or otherwise affect in any manner whatsoever the
right or power of the Company (or any Affiliate) to terminate Purchaser’s employment with the Company (or any Affiliate) at any
time for any reason or no reason, with or without cause.


 


7. RIGHTS
AS OWNER OF SHARES.


 


7.1 Encumbrances
on Vested Shares. Purchaser may grant a lien or security interest in, or pledge, hypothecate or encumber Vested Shares only if
each party to whom such lien or security interest is granted, or to whom such pledge, hypothecation or other encumbrance is made, agrees
in a writing satisfactory to the Company that: (a) such lien, security interest, pledge, hypothecation or encumbrance will not apply to
such Vested Shares after they are acquired by the Company and/or its assignees under this Agreement; and (b) the provisions of this
Agreement will continue to apply to such Vested Shares in the hands of such party and any transferee of such party. Purchaser may not
grant a lien or security interest in, or pledge, hypothecate or encumber, any Unvested Shares.


 


7.2 Encumbrance
on Shares. Subject to the terms and conditions of this Agreement, Purchaser will have all of the rights to the Shares from and
after the date that Purchaser delivers payment of the Purchase Price until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercise(s) the Right of First Refusal or the Repurchase Option. Upon an exercise of the Right of First Refusal
or the Repurchase Option, Purchaser will have no further rights as a holder of the Shares so purchased upon such exercise, except the
right to receive payment for the Shares so purchased in accordance with the provisions of this Agreement, and Purchaser will promptly
surrender the stock certificate(s) evidencing the Shares so purchased to the Company for transfer or cancellation.


 


8. ESCROW.
As security for Purchaser’s faithful performance of this Agreement, Purchaser agrees, immediately upon receipt of the stock certificate(s)
evidencing the Shares, to deliver such certificate(s), together with the Stock Powers executed by Purchaser and by Purchaser’s spouse,
if any (with the date, transferee, stock certificate number and number of Shares left blank), to the Secretary of the Company or other
designee of the Company (the “Escrow Holder”), who is hereby appointed to hold such certificate(s) and Stock
Powers in escrow and to take all such actions and to effectuate all such transfers and/or releases of such Shares as are in accordance
with the terms of this Agreement. Escrow Holder will act solely for the Company as its agent and not as a fiduciary. Purchaser and the
Company agree that Escrow Holder will not be liable to any party to this Agreement (or to any other party) for any actions or omissions
unless Escrow Holder is grossly negligent or intentionally fraudulent in carrying out the duties of Escrow Holder under this Agreement.
Escrow Holder may rely upon any letter, notice or other document executed with any signature purported to be genuine and may rely on the
advice of counsel and obey any order of any court with respect to the transactions contemplated by this Agreement. The Shares will be
released from escrow upon termination of the Right of First Refusal and the Repurchase Option.


 


9. TAX
CONSEQUENCES. PURCHASER UNDERSTANDS THAT PURCHASER MAY SUFFER ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER’S
PURCHASE OR DISPOSITION OF THE SHARES. PURCHASER REPRESENTS (a) THAT PURCHASER HAS CONSULTED WITH A TAX ADVISER THAT PURCHASER DEEMS
ADVISABLE IN CONNECTION WITH THE PURCHASE OR DISPOSITION OF THE SHARES AND (b) THAT PURCHASER IS NOT RELYING ON THE COMPANY FOR ANY
TAX ADVICE. Purchaser hereby acknowledges that Purchaser has been informed that, in addition to receiving taxable income upon the
receipt of any Shares paid for by the cancellation of compensation for services rendered, unless an election is filed by the Purchaser
with the Internal Revenue Service (and, if necessary, the proper state taxing authorities) within 30 days after the purchase of
the Shares to be effective, electing pursuant to Section 83(b) of the Internal Revenue Code (and similar state tax provisions, if applicable)
to be taxed currently on any difference between the Purchase Price of the Shares and their fair market value on the date of purchase,
there will be a recognition of taxable income to the Purchaser, measured by the excess, if any, of the fair market value of the Shares,
at the time they cease to be Unvested Shares, over the Purchase Price for such Shares. Purchaser represents that Purchaser has consulted
any tax advisors Purchaser deems advisable in connection with Purchaser’s purchase of the Shares and the filing of the election
under Section 83(b) and similar tax provisions. A form of Election under Section 83(b) is attached hereto as Exhibit 3 for
reference. PURCHASER HEREBY ASSUMES ALL RESPONSIBILITY FOR PROPERLY COMPLETING AND TIMELY FILING SUCH ELECTION AND PAYING ANY TAXES
RESULTING FROM SUCH ELECTION OR FROM FAILURE TO FILE THE ELECTION AND PAYING TAXES RESULTING FROM THE LAPSE OF THE REPURCHASE RESTRICTIONS
ON THE UNVESTED SHARES.

Law. This Agreement will be governed by and construed in accordance with the laws of the State of California, without giving effect
to that body of laws pertaining to conflict of laws.


 


12.5 Assignments;
Successors and Assigns. The Company may assign any of its rights and obligations under this Agreement, including but not limited
to its rights to repurchase Shares under the Right of First Refusal and the Repurchase Option. Any assignment of rights and obligations
by any other party to this Agreement requires the Company’s prior written consent. This Agreement, and the rights and obligations
of the parties hereunder, will be binding upon and inure to the benefit of their respective successors, assigns, heirs, executors, administrators
and legal representatives.


 


12.6 Entire
Agreement. This Agreement and the documents referred to herein constitute the entire agreement and understanding of the parties
with respect to the subject matter of this Agreement, and supersede all prior and contemporaneous understandings and agreements, whether
oral or written, between or among the parties hereto with respect to the specific subject matter hereof.


 


12.7 Amendment
and Waivers. This Agreement may be amended only by a written agreement executed by each of the parties hereto. No amendment of
or waiver of, or modification of any obligation under this Agreement will be enforceable unless set forth in a writing signed by the party
against which enforcement is sought. Any amendment effected in accordance with this Section will be binding upon all parties hereto and
each of their respective successors and assigns. No delay or failure to require performance of any provision of this Agreement shall constitute
a waiver of that provision as to that or any other instance. No waiver granted under this Agreement as to any one provision herein shall
constitute a subsequent waiver of such provision or of any other provision herein, nor shall it constitute the waiver of any performance
other than the actual performance specifically waived.


 


12.8 Severability.
If any provision of this Agreement is determined by any court or arbitrator of competent jurisdiction to be invalid, illegal or unenforceable
in any respect, such provision will be enforced to the maximum extent possible given the intent of the parties hereto. If such clause
or provision cannot be so enforced, such provision shall be stricken from this Agreement and the remainder of this Agreement shall be
enforced as if such invalid, illegal or unenforceable clause or provision had (to the extent not enforceable) never been contained in
this Agreement. Notwithstanding the forgoing, if the value of this Agreement based upon the substantial benefit of the bargain for any
party is materially impaired, which determination as made by the presiding court or arbitrator of competent jurisdiction shall be binding,
then both parties agree to substitute such provision(s) through good faith negotiations.


 


12.9 Counterparts;
Signatures. This Agreement may be executed in any number of counterparts, each of which when so executed and delivered will be
deemed an original, and all of which together shall constitute one and the same agreement. Counterparts may be delivered via facsimile,
electronic mail (including pdf or any electronic signature complying

with the U.S. federal ESIGN Act of 2000, e.g., www.docusign.com) or other transmission
