Ability to Bear Risk. The Investor is in a financial position to hold the Securities and is able to bear the economic risk and withstand a complete loss of his/her/its investment in the Securities.

Risk Factors; High Degree of Risk; Risk Factors. THE RISK FACTORS OF THE COMPANY SET FORTH IN THE COMPANY’S PUBLICLY AVAILABLE 10-Q FILING DATED AUGUST 15, 2014 ARE INCORPORATED HEREIN BY REFERENCE. THE INVESTOR RECOGNIZES THAT THE SECURITIES AS INVESTMENTS INVOLVE A HIGH DEGREE OF RISK. There can be no assurance that the Company will be able meet its business and financial objectives and commitments and the Company will need significant additional capital to continue as a going concern and/or to repay the Bridge Instrument in cash, which capital may not be available and will be difficult to obtain. The Investor recognizes that if the Company does not secure sufficient additional financing, it will likely be unable to continue as a going concern.

Professional Advice. The Investor has obtained, to the extent he/she/it deems necessary, his/her/its own professional advice with respect to the risks inherent in the investment in the Securities, the condition of the Company and the suitability of the investment in the Securities in light of his/her/its financial condition and investment needs.

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

Access to Information. The Investor has been given access to information relating the current financial condition of the Company and the risks associated therewith, and has utilized such access to his or her satisfaction for the purpose of obtaining information about the Company; particularly, the Investor has either attended (by phone or in person) or been given reasonable opportunity to attend a meeting with the management of the Company for the purpose of asking questions of, and receiving answers from, such management concerning the current condition and prospects of the Company NS the terms and conditions of the offering of the Securities, and has had the opportunity to obtain any additional information requested by investor regarding (a) the condition and prospects of the Company, and/or (b) necessary to verify the accuracy of information provided about the Company.

Purchase Entirely for Own Account. The Securities will be acquired for investment for the Investor’s own account, not as a nominee or agent, and not with a view to the distribution of any part thereof; the Investor has no present intention of selling, granting any participation in or otherwise distributing the Securities in a manner contrary to the Securities Act of 1933, as amended (the “Act”), or any applicable state securities or Blue Sky law, and the Investor does not have any contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any third person, with respect to any of the Securities.

Due Diligence. The Investor has been responsible for his/her/its own due diligence investigation of the Company and its business, and his/her/its analysis of the merits and risks of the investment made pursuant to this Agreement, including through the review of publicly available information about the Company, and is not relying on anyone else’s analysis or investigation of the Company, its business or the merits and risks of the Securities. In taking any action or performing any role relative to the arranging of the investments being made pursuant to this Agreement, the Investor has acted solely in his/her/its own interest and not in that of any of the Other Investors, and none of the Other Investors (or any of their respective employees or agents) has acted as an agent or fiduciary for the Investor.

Restricted Securities. The Investor realizes that (a) there are substantial restrictions on the transferability of the Securities (together with the securities issuable upon the exercise of the Warrants or the conversion of the Bridge Instrument (the “Conversion Securities”)) imposed by law and that such Securities or the Conversion Securities cannot be sold or transferred unless they are subsequently registered under the Act or an exemption from such registration is available. In this connection, the Investor represents that he/she/it is familiar with Rule 144 of the Securities and Exchange Commission (the “SEC”), as presently in effect, and understands the resale limitations imposed thereby and by the Act.

Exemption Reliance. The Investor has been advised that neither the Securities nor any of the Conversion Securities are being registered under the Act or the applicable state securities laws, but each is being offered and sold pursuant to exemptions from such laws, and that the Company’s reliance upon such exemptions is predicated in part on the Investor’s representations contained herein. If other than an individual, the Investor represents that it has not been organized for the purpose of investing in the Securities.

Further Limitations on Disposition. Without in any way limiting the representations set forth above, the Investor further agrees not to make any disposition of all or any portion of the Securities or the Conversion Securities unless and until such may be sold under the provisions of Rule 144 or there is then in effect a registration statement under the Act covering such proposed disposition and such disposition is made in accordance with such registration statement.

Residency. For purposes of the application of state securities laws, the Investor represents that he or she is a bona fide resident of, and is domiciled in, the state set forth in such investor’s address on page 6.
