Section 3.2 Title to Shares. Seller has good and valid title to the Stock free and clear of any lien, encumbrance, pledge, charge, security interest, mortgage, title retention agreement, option, equity or other adverse claim, and has not, in whole or in part, (a) assigned, transferred, hypothecated, pledged or otherwise disposed of the Stock or its ownership rights in such Stock or (b) given any person or entity any transfer order, power of attorney or other authority of any nature whatsoever with respect to such Stock.

Seller has duly taken all necessary action to authorize the execution, delivery and performance of this Agreement and the transactions contemplated hereby.

Section 3.4 Sophistication; Due Diligence. Seller acknowledges and agrees that the Company is not making any express or implied representations or warranties about the Company or in connection with the Repurchase. Seller has such knowledge and experience in financial and business matters and in making investment decisions of this type that it is capable of evaluating the merits and risks of making its investment decision regarding the Repurchase and of making an informed investment decision. Seller and/or Seller’s advisor(s) have had a reasonable opportunity to (a) evaluate all information and documents filed by the Company with the Securities and Exchange Commission pursuant to the Securities Act of 1933, as amended, and/or the Exchange Act of 1934, as amended, and (b) ask questions of and receive answers from a person or persons acting on behalf of the Company concerning the Stock and the Company and all such questions have been answered to Seller’s full satisfaction. Seller is not relying on the Company with respect to the tax and other economic considerations of the Repurchase, and Seller has relied on the advice of, or has consulted with, Seller’s own advisors.

Section 3.5 No Solicitation by Company. Seller acknowledges and agrees that the Company did not solicit Seller with respect to the Repurchase and that Seller contacted the Company concerning the Repurchase.

Section 3.6 Certain Information. Seller acknowledges and understands that the Company may possess material non-public information not known to Seller that may impact the value of the Stock that the Company has not disclosed to Seller, including, without limitation (i) certain financial and operational reports from management, (ii) information received by principals and employees of the Company in their capacities as directors, officers, significant stockholders and/or affiliates of the Company, (iii) information otherwise received on a confidential basis, and (iv) information received on a privileged basis from the attorneys and financial advisers representing the Company and the Board. Seller acknowledges that (a) the Company is under no obligation, fiduciary or otherwise, to disclose any information to Seller other than such information that the Company discloses publicly to all stockholders at such times as that information is in fact publicly disclosed by the Company and (b) the Company is relying on the representations, warranties and acknowledgments in this Section 3.6 in entering into this Agreement and engaging in the transactions contemplated hereby, and would not execute or deliver this Agreement or engage in such transactions in the absence of such representations, warranties and acknowledgements. Seller understands, based on its experience, the disadvantage to which Seller is subject due to the disparity of information between the Company and Seller, but nevertheless acknowledges that Seller has deemed it appropriate to engage in the Repurchase. Without limitation to the foregoing, Seller acknowledges that he was a member of the board of directors of the Company until June 5, 2017, and therefore, in addition to any publicly available information and information available to him as a stockholder of the Company, Seller had access to the same information with respect to the Company as was generally available to the Company’s directors through June 5, 2017.

Section 3.7 No Consents Required.

Section 3.8 No Conflicts. The execution, delivery and performance by Seller of this Agreement, and the consummation of the transactions contemplated hereby, will not result in a violation or breach of any provision of any law, rule, regulation, judgment, order or decree of any governmental authority as of the date hereof by the Seller.
