9. Confidential Information. The Consultant recognizes and acknowledges that certain information, including, but not limited to, information pertaining to the financial condition of the Company, its systems, methods of doing business, agreements with customers or suppliers, or other aspects of the business of the Company or which are sufficiently secret to derive economic value from not being disclosed (hereinafter “Confidential Information”) may be made available or otherwise come into the possession of the Consultant by reason of this engagement with the Company. Accordingly, the Consultant agrees that no agent, employee, or representative will (either during or after the term of this Agreement) disclose any Confidential Information to any person, firm, corporation, association, or other entity for any reason or purpose whatsoever or make use to its or their personal advantage or to the advantage of any third party, of any Confidential Information, without the prior written consent of the Company. The parties hereto agree that the provisions of this Section shall not apply with respect to any information that the Consultant can document (i) is or becomes (through no improper action or inaction by the Consultant or any affiliate, agent, consultant or employee) generally available to the public, or (ii) was in its possession or known by it without any limitation on use or disclosure prior to the Effective Date. The Consultant shall, upon termination of this engagement, return to the Company, and shall cause his agents, employees, and representatives to return to the Company, all documents which reflect Confidential Information (including copies thereof). Notwithstanding anything heretofore stated in this paragraph, the Consultant’s obligations under this Agreement shall not, after termination of Consultant’s engagement with the Company, apply to information which has become generally available to the public without any action or omission of the Consultant (except that any Confidential Information which is disclosed to any third party by an employee or representative of the Company who is authorized to make such disclosure shall be deemed to remain confidential and protectable under this provision).

10. Trading Practices. So long as the Consultant is in possession of any material non-public information of the Company, the Consultant shall not, directly or indirectly engage in the purchase or sale the common stock of the Company. During the Term of this Agreement, and for a period of one year after the termination of this Agreement, the Consultant shall not, directly or indirectly, engage in any short selling activities of the common stock of the Company.

11. Independent Contractor. The Consultant agrees that in performing this Agreement, it is acting as an independent contractor and not as an employee, representative, or agent of the Company and shall provide all facilities and equipment necessary to fulfill its obligations hereunder. As an independent contractor, the Consultant shall make no representation as an agent or employee of the Company, shall have no authority to bind the Company or incur other obligations on behalf of the Company, and shall not be eligible for any benefits which the Company may provide to its employees. Likewise, the Company shall have no authority to bind or incur obligations on behalf of the Consultant. All persons hired or retained by Consultant to perform this Agreement, including, but not limited to, its employees, representatives, and agents, shall be employees or contractors of the Consultant and shall not be construed as employees or agents of the Company in any respect. The Consultant shall be responsible for all taxes, insurance and other costs and payments legally required to be withheld or provided in connection with Consultant’s performance of this Agreement, including without limitation, all withholding taxes, worker’s compensation insurance, and similar costs. The Consultant shall abide by all laws, rules, and regulations pertaining to the Services to be provided hereunder.

12. Securities Law Representations and Warranties. The Consultant has been advised that the issuance of the Shares is not registered under the Securities Act of 1933, as amended (the “Act”), or applicable state securities laws, but are being sold pursuant to exemptions from such laws, and that the Company’s reliance upon such exemptions is predicated in part on the Consultant’s representations contained herein. The Consultant acknowledges that the Company is relying, in part, upon the Consultant’s representations and warranties contained herein for the purpose of qualifying the issuance of the Shares for applicable exemptions from registration or qualification pursuant to federal or state securities laws, rules and regulations.

12.1 Acquired Entirely for Own Account. The Shares will be acquired for the Consultant’s own account, not as a nominee or agent, and not with a view to distributing all or any part thereof. The Consultant has no present intention of selling, granting any participation in or otherwise distributing any of the Shares in a manner contrary to the Act or any applicable state securities law. The Consultant 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.

12.2 Due Diligence. The Consultant has been solely responsible for its own due diligence investigation of the Company and its business, and its analysis of the merits and risks of the investment made pursuant to this Agreement, and are not relying on anyone else’s analysis or investigation of the Company, its business or the merits and risks of the Shares other than professional advisors employed specifically by the Consultant to assist the Consultant.

12.3 Access to Information. The Consultant believes it has been given access to full and complete information regarding the Company, including, in particular, the current financial condition and lack of tangible assets of the the Company and the risks associated therewith, and has utilized such access to its satisfaction for the purpose of obtaining information about the Company; particularly, the Consultant has either attended or been given reasonable opportunity to attend a meeting with management of the Company, for the purpose of asking questions of, and receiving answers from, such persons concerning the terms and conditions of the issuance of the Shares and to obtain any additional information, to the extent reasonably available, necessary to verify the accuracy of information provided to the Consultant about the Company.

12.4 Sophistication. The Consultant, either alone or with the assistance of its professional advisors, is a sophisticated investor, is able to fend for itself in the transactions contemplated by this Agreement, and has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the prospective investment in the Shares.

12.5 Suitability. The investment in the Shares is suitable for the Consultant based upon its investment objectives and financial needs, and the Consultant has adequate net worth and means for providing for their current financial needs and contingencies and has no need for liquidity of investment with respect to the Shares. The Consultant’s overall commitment to investments that are illiquid or not readily marketable is not disproportionate to its net worth, and investment in the Shares will not cause such overall commitment to become excessive.

12.6 Professional Advice. The Consultant has obtained, to the extent it deems necessary, its own professional advice with respect to the risks inherent in the investment in the Shares, the condition of the Company and the suitability of the investment in the Shares in light of the Consultant’s financial condition and investment needs.

12.7 Ability to Bear Risk. The Consultant is in a financial position to purchase and hold the Shares and is able to bear the economic risk and withstand a complete loss of its investment in the Shares.

12.8 Accredited Investor. The Consultant is an “accredited investor” within the meaning of Rule 501(a)(3) of Regulation D promulgated under the Act.

12.9 Restricted Securities. The Consultant realizes that (a) the Shares have not been registered under the Act, are characterized under the Act as “restricted securities” and, therefore, cannot be sold or transferred unless subsequently registered under the Act or an exemption from such registration is available, and (b) there is presently a limited public market for the Shares and the Consultant would most likely not be able to liquidate its investment in the event of an emergency or to pledge the Shares as collateral security for loans. The Consultant’s financial condition is such that it is unlikely that the Consultant would need to dispose of any of the Shares in the foreseeable future. In this connection, the Consultant represents that it is familiar with Rule 144 of the SEC, as presently in effect, and understands the resale limitations imposed thereby and by the Act.
