reasonable out-of-pocket expenses incurred in attending each meeting of the Board or any committee thereof.

Board shall meet on at least a monthly basis, unless otherwise agreed by a majority of the members of the Board who are not employees

(the “Plan”). The Plan shall comply with the following rules:


 


(a)          Subject
to (b), the total number of shares of Common Stock subject to options or other awards granted or offered to be granted under the
Plan shall not, assuming each outstanding option will be exercised, when aggregated with all shares of capital stock issued as

4.            Confidentiality.
Each Stockholder agrees that he, she or it will keep confidential and will not disclose, divulge or use for any purpose, other
than to monitor its investment in the Company, any Confidential Information, unless such Confidential Information (a) is known
or becomes known to the public in general (other than as a result of a breach of this Section 4 by such Stockholder), (b) is or
has been independently developed or conceived by the Stockholder without use of the Company’s Confidential Information or (c) is
or has been made known or disclosed to the Stockholder by a third party without a breach of any obligation of confidentiality such
third party may have to the Company; provided, however, that a Stockholder may disclose Confidential Information (i) to
its attorneys, accountants, consultants, and other professionals to the extent necessary to obtain their services in connection
with monitoring its investment in the Company, (ii) to any prospective purchaser of any Shares from such Stockholder as long as
such prospective purchaser agrees to be bound by the provisions of this Section 4, (iii) to any Affiliated Party of such Stockholder,
provided that such party is obligated not to disclose, divulge or use any Confidential Information to the same extent as the Stockholders,
or (iv) as may otherwise be required by law, provided that the Stockholder takes reasonable steps to minimize the extent of any
such required disclosure. Notwithstanding the foregoing, such information shall not be deemed confidential for the purpose of enforcing
this Agreement. Notwithstanding anything to the contrary, in the event of a pending, threatened or actual breach of a Stockholder’s
obligations under this Section 4, the Company shall have the right to seek injunctive relief in a court of competent jurisdiction
to enjoin such breach.

5.1           Transfer
of Rights. This Agreement, and the rights and obligations of each Stockholder hereunder, may be assigned by such Stockholder
to (a) any person or entity to which Shares are transferred by such Stockholder, or (b) to any Affiliated Party of such Stockholder,
and, in each case, such transferee shall be deemed a “Stockholder” for purposes of this Agreement; provided that
such assignment of rights shall be contingent upon the transferee providing a written instrument to the Company notifying the Company
of such transfer and assignment and agreeing in writing to be bound by the terms of this Agreement.

more than one entity or person within any such group of affiliated entities or persons).


 


6.            General.


 


6.1          Severability.
The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other

Performance. In addition to any and all other remedies that may be available at law in the event of any breach of this Agreement,
each Stockholder shall be entitled to specific performance of the agreements and obligations of the Company hereunder and to such
other injunctive or other equitable relief as may be granted by a court of competent jurisdiction.


 


6.3          Governing Law. This Agreement shall be governed

of Prior Agreement; Complete Agreement. The Company and the Existing Stockholders holding Shares (as defined in the Prior Agreement)
representing at least 66 2/3% of the voting power of all Shares (as defined in the Prior Agreement) held by Stockholders (as defined
in the Prior Agreement) agree that, as of the date of this Agreement, (i) the Prior Agreement is hereby amended and restated in
its entirety by this Agreement, (ii) the provisions of the Prior Agreement shall no longer be of any force or effect and (iii)
this Agreement constitutes the entire agreement and understanding of the parties hereto with respect to the subject matter hereof

and Waivers. This Agreement may be amended or terminated and the observance of any term of this Agreement may be waived with
respect to all parties to this Agreement (either generally or in a particular instance and either retroactively or prospectively),
with the written consent of the Company and Stockholders holding Shares representing at least 66 2/3% of the voting power of all
Shares then held by Stockholders. Notwithstanding the foregoing, this Agreement may not be amended or terminated and the observance
of any term hereunder may not be waived with respect to any Stockholder without the written consent of such Stockholder unless
such amendment, termination or waiver applies to all Stockholders in the same fashion (it being agreed that a waiver of the provisions
of Section 2 with respect to a particular transaction shall be deemed to apply to all Qualified Stockholders in the same fashion
if such waiver does so by its terms, notwithstanding the fact that certain Qualified Stockholders may nonetheless, by agreement
with the Company, purchase securities in such transaction). The Company shall give prompt written notice of any amendment or termination
hereof or waiver hereunder to any party hereto that did not consent in writing to such amendment, termination or waiver. Any amendment,
termination or waiver effected in accordance with this Section 6.6 shall be binding on all parties hereto, even if they do not
execute such consent. No waivers of or exceptions to any term, condition or provision of this Agreement, in any one or more instances,
shall be deemed to be, or construed as, a further or continuing waiver of any such term, condition or provision.


 


6.7           Pronouns.

forms, and the singular form of nouns and pronouns shall include the plural, and vice versa.

Facsimile Signatures. This Agreement may be executed in any number of counterparts (including, in the case of the Stockholders,
a counterpart signature page to the Transaction Documents (as defined in the subscription agreements between the Company and individual
Stockholders)), each of which shall be deemed to be an original, and all of which together shall constitute one and the same document.
This Agreement (including such counterpart signature pages) may be executed by facsimile signatures.


 


6.9           Section
Headings and References. The section headings are for the convenience of the parties and in no way alter, modify, amend, limit
