3.2 Representations and Warranties of CPRIT. CPRIT hereby represents and warrants as of the date hereof to the Company as follows:

(a) Organization; Authority. CPRIT is an entity established under Article III, Section 67 of the Texas Constitution with the requisite statutory power and authority to enter into and to consummate the transactions contemplated by each of the Transaction Documents to which it is a party and otherwise to carry out its obligations hereunder and thereunder. The execution and delivery of each of the Transaction Documents to which it is a party and the consummation by it of the transactions contemplated hereby and thereby have been duly authorized by all necessary statutory action on the part of CPRIT. Each Transaction Document to which it is a party has been duly executed by CPRIT, and when delivered by CPRIT in accordance with the terms hereof, will constitute the legal, valid and binding obligation of CPRIT, enforceable against it in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium, liquidation or similar laws relating to, or affecting generally the enforcement of, creditors’ rights and remedies or by other equitable principles of general application.

(b) No Conflicts. The execution, delivery and performance by CPRIT of the Transaction Documents to which it is a party and the consummation by CPRIT of the transactions contemplated hereby and thereby do not and will not (i) result in a violation of the organizational documents of CPRIT, or (ii) result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority (including federal and state securities laws) to which CPRIT is subject, except in the case of clause (ii) such as would not, individually or in the aggregate, have or reasonably be expected to have a material adverse effect on the ability of CPRIT to perform its obligations hereunder.

(c) Government Consents and Approvals. CPRIT is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any federal, state, local or other governmental authority or other similar Person in connection with the execution, delivery and performance by CPRIT of the Transaction Documents to which it is a party, other than those that have been made or obtained prior to the Effective Date.

(d) Investment Intent. CPRIT understands that the Shares are “restricted securities” and have not been registered under the Securities Act or any applicable state securities law and is acquiring the Shares for its own account and not with a view to, or for distributing or reselling such Shares or any part thereof in violation of the Securities Act or any applicable state securities laws. CPRIT is acquiring the Shares hereunder in the ordinary course of its business. CPRIT does not presently have any agreement, plan or understanding, directly or indirectly, with any Person to distribute or effect any distribution of any of the Shares (or any securities which are derivatives thereof) to or through any Person; CPRIT is not a registered broker-dealer under Section 15 of the Exchange Act or an entity engaged in a business that would require it to be so registered as a broker-dealer.

(e) Status. At the time CPRIT was offered the Shares, it was, and at the date hereof it is an “accredited investor” as defined in Rule 501(a) under the Securities Act.

(f) General Solicitation. CPRIT is not purchasing the Shares as a result of any advertisement, article, notice or other communication regarding Shares published in any newspaper, magazine or similar media or broadcast over television or radio or presented at any seminar or any other general advertisement.

(g) Experience. CPRIT, either alone or together with its representatives, has such knowledge, sophistication and experience in business and financial matters so as to be capable of evaluating the merits and risks of the prospective investment in the Shares, and has so evaluated the merits and risks of such investment. CPRIT is able to bear the economic risk of an investment in the Shares and, at the present time, is able to afford a complete loss of such investment.

(h) Access to Information. CPRIT acknowledges that it has had the opportunity to review any materials that it has requested from the Company and has been afforded (i) the opportunity to ask such questions as it has deemed necessary of, and to receive answers from, representatives of the Company concerning the terms and conditions of the offering of the Shares and the merits and risks of investing in the Shares; (ii) access to information about the Company and its financial condition, results of operations, business, properties, management and prospects sufficient to enable CPRIT to evaluate its investment; and (iii) the opportunity to obtain such additional information that the Company possesses or can acquire without unreasonable effort or expense that is necessary to make an informed investment decision with respect to the investment. Neither such inquiries nor any other investigation conducted by or on behalf of CPRIT or its representatives or counsel shall modify, amend or affect CPRIT’s right to rely on the truth, accuracy and completeness of any such materials and the Company’s representations and warranties contained in the Transaction Documents. CPRIT has sought such accounting, legal and tax advice as it has considered necessary to make an informed decision with respect to its acquisition of the Shares.

(i) Independent Investment Decision. CPRIT has independently evaluated the merits of its decision to purchase Shares pursuant to the Transaction Documents CPRIT 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 the Shares.
