 (b) Authority. The execution, delivery and performance by the Company of this
Agreement and the consummation of the transactions contemplated hereby (i) are within the power of the Company and (ii) have been duly authorized by all necessary corporate action on the part of the Company. 

(c) Enforceability. This Agreement has been duly executed and delivered by the Company and constitutes a legal, valid and binding
obligation of the Company, enforceable against the Company in accordance with its terms, except as limited by bankruptcy, insolvency or other laws 







 
of general application relating to or affecting the enforcement of creditors’ rights generally and general principles of equity. 

3. Representations and Warranties of Investor. Investor represents and warrants to the Company on the date hereof and on
the Closing Date: 
 (a) Binding Obligation. Such Investor has full legal capacity, power and authority to execute and deliver this
Agreement and to perform its obligations hereunder. This Agreement is a valid and binding obligation of such Investor, enforceable in accordance with its terms, except as limited by bankruptcy, insolvency or other laws of general application
relating to or affecting the enforcement of creditors’ rights generally and general principles of equity. 
 (b) Securities Law
Compliance. Such Investor has been advised that the Shares are characterized as “restricted securities” under the federal securities laws and have not been registered under the Securities Act, or any state securities laws and,
therefore, cannot be resold unless they are registered under the Securities Act and applicable state securities laws or unless an exemption from such registration requirements is available. Such Investor is aware that the Company is under no
obligation to effect any such registration with respect to the Shares, or to file for or comply with any exemption from registration. Such Investor has not been formed solely for the purpose of making this investment and is purchasing the Shares for
its own account for investment, not as a nominee or agent, and not with a view to, or for resale in connection with, any immediate distribution thereof, and that such Investor has no present intention of selling, granting any participation in, or
otherwise distributing the same. Such Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participation to such person or to any third person, with respect to any of the Shares. Such
Investor is an investor in securities of companies in the development stage and acknowledges that it has such knowledge and experience in financial and business matters that such Investor is capable of evaluating the merits and risks of such
investment, is able to incur a complete loss of such investment and is able to bear the economic risk of such investment for an indefinite period of time. Such Investor is an “accredited investor” as such term is defined in Rule 501 of
Regulation D under the Securities Act. The offer to sell the Shares was directly communicated to such Investor by the Company. At no time was such Investor presented with or solicited by any leaflet, advertisement, article, notice or other
communication published in any newspaper, magazine, or similar media or broadcast over television or radio, or any other form of general advertising, or solicited or invited to attend a promotional meeting or any seminar or meeting by any general
solicitation or general advertising. 
 (c) Access to Information. Such Investor acknowledges that the Company has given such
Investor access to the corporate records and accounts of the Company and to all information in its possession relating to the Company, has made its officers and representatives available for interview by such Investor, and has furnished such
Investor with all documents and other information required for such Investor to make an informed decision with respect to the purchase of the Shares. 

(d) Brokers or Finders. Such Investor has not engaged any brokers, finders or agents, and the Company has not and will not incur,
directly or indirectly, as a result of any action taken by Investor, any liability for brokerage or finders’ fees or agents’ commissions or any similar charges in connection with this Agreement or the Shares.

(2) Investor has notified the Company of the proposed transfer and has furnished the Company with an opinion of counsel, reasonably satisfactory to the Company, that such transfer will not require registration of such shares under the
