bond, debenture, note or other evidence of indebtedness, lease, contract, indenture, mortgage, deed of trust, loan agreement, joint
venture or other agreement or instrument to which the Company or any Subsidiary is a party or by which it or any of its Subsidiaries

by the Investors with the terms and conditions hereof and the truthfulness and accuracy of the Investors’ representations
and warranties set forth in Section 5 hereof, except in the case of clauses (i), (iii) and (iv) for any such conflicts, violations
or defaults which are not reasonably likely to have a Material Adverse Effect, individually or in the aggregate, or (B) result
in the creation or imposition of any lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material
properties or assets of the Company or any Subsidiary or an acceleration of indebtedness pursuant to any obligation, agreement
or condition contained in any material bond, debenture, note or any other evidence of indebtedness or any material indenture, mortgage,
deed of trust or any other agreement or instrument to which the Company or any Subsidiary is a party or by which any of them is
bound or to which any of the material property or assets of the Company or any Subsidiary is subject. No consent, approval, authorization

Each Investor, severally and not jointly, represents and warrants to, and covenants with, the Company that: (i) the Investor
is an “accredited investor” as defined in Rule 501(a) of Regulation D under the Securities Act and is also knowledgeable,
sophisticated and experienced in making, and is qualified to make, decisions with respect to investments in shares presenting an
investment decision like that involved in the purchase of the Preferred Stock, including investments in securities issued by the
Company and investments in comparable companies, and has requested, received, reviewed and considered all information it deemed
relevant in making an informed decision to purchase the Preferred Stock; (ii) the Investor is acquiring the Preferred Stock set
forth in Annex I to the Agreement in the ordinary course of business and for its own account for investment only and with no present
intention of distributing any of such Preferred Stock or the Securities or any arrangement or understanding with any other persons
regarding the distribution of such Preferred Stock or the Securities, except in accordance with applicable securities law; (iii)
the Investor will not, directly or indirectly, offer, sell, pledge, transfer or otherwise dispose of (or solicit any offers to

hereby and has taken all necessary action to authorize the execution, delivery and performance of this Agreement, (ii) the execution
and delivery of this Agreement, the purchase of the Preferred Stock under the Agreement, the fulfillment of the terms of the Agreement
and the consummation of the transactions contemplated hereby will not conflict with or constitute a violation of, or default (with

constitutes a valid and binding obligation of the Investor enforceable against the Investor in accordance with its terms, except
as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’
and contracting parties’ rights generally and except as enforceability may be subject to general principles of equity (regardless
of whether such enforceability is considered in a proceeding in equity or at law) and except as the indemnification agreements
of the Investors herein may be legally unenforceable.

5.5             
Investor will not use any of the restricted Preferred Stock or underlying Common Stock acquired pursuant to this Agreement
to cover any short position in the Common Stock of the Company if doing so would be in violation of applicable securities laws.

5.6             
Each Investor understands that nothing in the Exchange Act Documents, this Agreement or any other materials presented to
the Investors in connection with the purchase and sale of the Preferred Stock constitutes legal, tax or investment advice. The
Investor has consulted such legal, tax and investment advisors as it, in its sole discretion, has deemed necessary or appropriate
in connection with its purchase of Preferred Stock.

5.7

at any seminar or any other general solicitation or general advertisement.

 

5.9             
Each Investor has independently evaluated the merits of its decision to purchase Preferred Stock, such decision has been
independently made by such Investor and such Investor confirms that it has only relied on the advice of its own business and/or
legal counsel and not on the advice of the Company’s or any other Investor’s business and/or legal counsel in making
such decision.

6.                 
Survival of Representations, Warranties and Agreements. Notwithstanding any investigation made by any party
to this Agreement, all covenants, agreements, representations and warranties made by the Company and the Investors herein shall
survive the execution of this Agreement, the delivery to the Investors of the Preferred Stock being purchased and the payment therefor.

7.                 
Right to Appoint Board Members. Marc Lehmann, a current member of the Company’s
board of directors, shall tender his resignation effective as of the Closing and Meisel shall have the right to name such replacement

or its right to purchase the Securities that would constitute a sale within the meaning of the Securities Act except as otherwise

Non-Contravention. The execution and delivery of the Agreement, the issuance and sale of the Preferred Stock under

bond, debenture, note or other evidence of indebtedness, lease, contract, indenture, mortgage, deed of trust, loan agreement, joint
venture or other agreement or instrument to which the Company or any Subsidiary is a party or by which it or any of its Subsidiaries
or their respective properties are bound, (ii) the charter, bylaws or other organizational documents of the Company or any Subsidiary,

by the Investors with the terms and conditions hereof and the truthfulness and accuracy of the Investors’ representations
and warranties set forth in Section 5 hereof, except in the case of clauses (i), (iii) and (iv) for any such conflicts, violations
or defaults which are not reasonably likely to have a Material Adverse Effect, individually or in the aggregate, or (B) result
in the creation or imposition of any lien, encumbrance, claim, security interest or restriction whatsoever upon any of the material
properties or assets of the Company or any Subsidiary or an acceleration of indebtedness pursuant to any obligation, agreement
or condition contained in any material bond, debenture, note or any other evidence of indebtedness or any material indenture, mortgage,
