The Purchaser understands that the offering and sale of the Units is intended to be exempt from registration under the Securities Act, by virtue of Section 4(2) thereof and the provisions of Regulation D (“Regulation D”) as promulgated by the United States Securities and Exchange Commission (the “SEC”) thereunder, based, in part, upon the representations, warranties and agreements of the Purchaser contained in this Subscription Agreement;

(b) Prior to the execution of this Subscription Agreement, the Purchaser and the Purchaser's attorney, accountant, purchaser representative and/or tax adviser, if any (collectively, the “Advisers”), have received the Memorandum and all other documents requested by the Purchaser, have carefully reviewed them and understand the information contained therein;

(c) Neither the SEC nor any state securities commission or other regulatory authority has approved the Units, the Common Stock, the Warrants or the Warrant Shares, or passed upon or endorsed the merits of the offering of Units or confirmed the accuracy or determined the adequacy of the Memorandum.

(d) All documents, records, and books pertaining to the investment in the Units (including, without limitation, the Memorandum) have been made available for inspection by such Purchaser and its Advisers, if any;

(e) The Purchaser and its Advisers, if any, have had a reasonable opportunity to ask questions of and receive answers from a person or persons acting on behalf of the Company concerning the offering of the Units and the business, financial condition and results of operations of the Company and Matinas, and all such questions have been answered to the full satisfaction of the Purchaser and its Advisers, if any;

(q) The Purchaser and the Advisers, if any, have had the opportunity to obtain any additional information, to the extent the Company and/or Matinas have such information in its possession or could acquire it without unreasonable effort or expense, necessary to verify the accuracy of the information contained in the Memorandum and all documents received or reviewed in connection with the purchase of the Units and have had the opportunity to have representatives of the Company and Matinas provide them with such additional information regarding the terms and conditions of this particular investment and the financial condition, results of operations, business of the Company and Matinas deemed relevant by the Purchaser or the Advisers, if any, and all such requested information, to the extent the Company had such information in its possession or could acquire it without unreasonable effort or expense, has been provided to the full satisfaction of the Purchaser and the Advisers, if any;

(r) Any information which the Purchaser has heretofore furnished or is furnishing herewith to the Company, Matinas or the Placement Agent is complete and accurate and may be relied upon by the Company, Matinas and the Placement Agent in determining the availability of an exemption from registration under federal and state securities laws in connection with the offering of securities as described in the Memorandum. The Purchaser further represents and warrants that it will notify and supply corrective information to the Company, Matinas and the Placement Agent immediately upon the occurrence of any change therein occurring prior to the Company's issuance of the securities contained in the Units;

(s) The Purchaser has significant prior investment experience, including investment in non-listed and non-registered securities. The Purchaser is knowledgeable about investment considerations in development-stage companies with limited operating histories. The Purchaser has a sufficient net worth to sustain a loss of its entire investment in the Company in the event such a loss should occur.

(w) Within five (5) days after receipt of a request from the Company, Matinas or the Placement Agent, the Purchaser will provide such information and deliver such documents as may reasonably be necessary to comply with any and all laws and ordinances to which the Company, Matinas or the Placement Agent is subject;

(x) The Purchaser's substantive relationship with the Placement Agent or subagent through which the Purchaser is subscribing for Units predates the Placement Agent's or such subagent's contact with the Purchaser regarding an investment in the Units;

(y) THE SECURITIES OFFERED HEREBY HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND ARE BEING OFFERED AND SOLD IN RELIANCE ON EXEMPTIONS FROM THE REGISTRATION REQUIREMENTS OF SAID ACT AND SUCH LAWS. THE SECURITIES ARE SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER SAID ACT AND SUCH LAWS PURSUANT TO REGISTRATION OR EXEMPTION THEREFROM. THE SECURITIES HAVE NOT BEEN RECOMMENDED, APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION, ANY STATE SECURITIES COMMISSION OR ANY OTHER REGULATORY AUTHORITY, NOR HAVE ANY OF THE FOREGOING AUTHORITIES PASSED UPON OR ENDORSED THE MERITS OF THIS OFFERING OR THE ACCURACY OR ADEQUACY OF THE MEMORANDUM OR THIS SUBSCRIPTION AGREEMENT. ANY REPRESENTATION TO THE CONTRARY IS UNLAWFUL;

(z) In making an investment decision investors must rely on their own examination of the Company, Matinas and the terms of the Offering, including the merits and risks involved. The Purchaser should be aware that it will be required to bear the financial risks of this investment for an indefinite period of time;

(aa) (For ERISA plans only) The fiduciary of the ERISA plan (the “Plan”) represents that such fiduciary has been informed of and understands the Company’s investment objectives, policies and strategies, and that the decision to invest “plan assets” (as such term is defined in ERISA) in the Company is consistent with the provisions of ERISA that require diversification of plan assets and impose other fiduciary responsibilities. The Purchaser fiduciary or Plan (a) is responsible for the decision to invest in the Company; (b) is independent of the Company or any of its affiliates; (c) is qualified to make such investment decision; and (d) in making such decision, the Purchaser fiduciary or Plan has not relied primarily on any advice or recommendation of the Company or any of its affiliates;

(bb) The Purchaser should check the Office of Foreign Assets Control (“OFAC”) website at <http://www.treas.gov/ofac> before making the following representations. The Purchaser represents that the amounts invested by it in the Company in the Offering were not and are not directly or indirectly derived from activities that contravene federal, state or international laws and regulations, including anti-money laundering laws and regulations. Federal regulations and Executive Orders administered by OFAC prohibit, among other things, the engagement in transactions with, and the provision of services to, certain foreign countries, territories, entities and individuals. The lists of OFAC prohibited countries, territories, persons and entities can be found on the OFAC website at <http://www.treas.gov/ofac>.

Please be advised that the Company may not accept any amounts from a prospective investor if such prospective investor cannot make the representation set forth in the preceding paragraph. The Purchaser agrees to promptly notify the Company and the Placement Agent should the Purchaser become aware of any change in the information set forth in these representations. The Purchaser understands and acknowledges that, by law, the Company may be obligated to “freeze the account” of the Purchaser, either by prohibiting additional subscriptions from the Purchaser, declining any redemption requests and/or segregating the assets in the account in compliance with governmental regulations, and the Placement Agent may also be required to report such action and to disclose the Purchaser’s identity to OFAC. The Purchaser further acknowledges that the Company may, by written notice to the Purchaser, suspend the redemption rights, if any, of the Purchaser if the Company reasonably deems it necessary to do so to comply with anti-money laundering regulations applicable to the Company and the Placement Agent or any of the Company’s other service providers. These individuals include specially designated nationals, specially designated narcotics traffickers and other parties subject to OFAC sanctions and embargo programs;

(dd) To the best of the Purchaser’s knowledge, none of: (1) the Purchaser; (2) any person controlling or controlled by the Purchaser; (3) if the Purchaser is a privately-held entity, any person having a beneficial interest in the Purchaser; or (4) any person for whom the Purchaser is acting as agent or nominee in connection with this investment is a senior foreign political figure,² or any immediate family³ member or close associate⁴ of a senior foreign political figure, as such terms are defined in the footnotes below; and
