Officer, or in any case to such email address or address as subsequently modified by written notice given in accordance with this Section
6.5. If notice is given to the Company, a copy (which copy shall not constitute notice) shall also be sent to White Summers Caffee

Law (the “DGCL”), as amended or superseded from time to time, by electronic transmission pursuant to Section 232 of
the DGCL (or any successor thereto) at the electronic mail address set forth below such Investor’s name on the Schedules hereto,
as updated from time to time by notice to the Company, or as on the books of the Company. To the extent that any notice given by means
of electronic transmission is returned or undeliverable for any reason, the foregoing consent shall be deemed to have been revoked until
a new or corrected electronic mail address has been provided, and such attempted electronic notice shall be ineffective and deemed to
not have been given. Each Investor agrees to promptly notify the Company of any change in such stockholder’s electronic mail address,
and that failure to do so shall not affect the foregoing.

6.6 Amendments
and Waivers. Any term of this Agreement may be amended, modified or terminated and the observance of any term of this Agreement may
be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of
(i) the Company, (ii) the holders of at least 60% of the then-outstanding shares of Series A Preferred Stock, and (iii) the holders of
at least 50% of the then-outstanding shares of Common Stock and Series A Preferred Stock, voting together as a single class on an as-converted
basis; provided that the Company may in its sole discretion waive compliance with Section 2.12(c) (and the Company’s
failure to object promptly in writing after notification of a proposed assignment allegedly in violation of Section 2.12(c) shall
be deemed to be a waiver); and provided further that any provision hereof may be waived by any waiving party on such party’s
own behalf, without the consent of any other party. Notwithstanding the foregoing, (a) this Agreement may not be amended, modified or
terminated and the observance of any term hereof may not be waived with respect to any Investor without the written consent of such Investor,
unless such amendment, modification, termination, or waiver applies to all Investors in the same fashion (it being agreed that a waiver
of the provisions of Section 4 with respect to a particular transaction shall be deemed to apply to all Investors in the same
fashion if such waiver does so by its terms, notwithstanding the fact that certain Investors may nonetheless, by agreement with the Company,
purchase securities in such transaction) and (b) Sections 3.1 and 3.2 and any other section of this Agreement applicable to the
Major Investors (including this clause (b) of this Section 6.6) may be amended, modified, terminated or waived with only
the written consent of the Company and the holders of at least a majority of the Registrable Securities then outstanding and held by
the Major Investors. Notwithstanding the foregoing, Schedule A hereto may be amended by the Company from time to time to add transferees
of any Registrable Securities in compliance with the terms of this Agreement without the consent of the other parties; and Schedule
A hereto may also be amended by the Company after the date of this Agreement without the consent of the other parties to add information
regarding any additional Investor who becomes a party to this Agreement in accordance with Section 6.9. The Company shall give
prompt notice of any amendment, modification or termination hereof or waiver hereunder to any party hereto that did not consent in writing
to such amendment, modification, termination, or waiver. Any amendment, modification, termination, or waiver effected in accordance with
this Section 6.6 shall be binding on all parties hereto, regardless of whether any such party has consented thereto. No waivers
of or exceptions to any term, condition, or provision of this Agreement, in any one (1) 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 Severability.
In case any one (1) or more of the provisions contained in this Agreement is for any reason held to be invalid, illegal or unenforceable
in any respect, such invalidity, illegality, or unenforceability shall not affect any other provision of this Agreement, and such invalid,
illegal, or unenforceable provision shall be reformed and construed so that it will be valid, legal, and enforceable to the maximum extent
permitted by law.

6.8 Aggregation
of Stock; Apportionment. All shares of Registrable Securities held or acquired by Affiliates shall be aggregated together for the
purpose of determining the availability of any rights under this Agreement and such Affiliated Persons may apportion such rights as among
themselves in any manner they deem appropriate.

6.9 Additional
Investors. Notwithstanding anything to the contrary contained herein, if the Company issues additional shares of Series A Preferred
Stock after the date hereof, pursuant to the Purchase Agreement, any purchaser of such shares of Series a Preferred Stock may become
a party to this Agreement by executing and delivering an additional counterpart signature page to this Agreement, and thereafter shall
be deemed an “Investor” for all purposes hereunder. No action or consent by the Investors shall be required for such joinder
to this Agreement by such additional Investor, so long as such additional Investor has agreed in writing to be bound by all of the obligations
as an “Investor” hereunder.
