SELLER is duly qualified as a foreign corporation to do business and is in good standing in each jurisdiction where the nature of the business conducted or property owned by it makes such qualification necessary, unless the failure to be so qualified or in good standing, as the case may be, would not have or would not reasonably be expected to result in (i) a material adverse effect on the legality, validity or enforceability of this Agreement or any other document in connection with the Placement, (ii) a material adverse effect on the results of operations, assets, business or financial condition of SELLER, or (iii) a material adverse effect on SELLER’s ability to perform in any material respect on a timely basis its obligations under this Agreement (any of (i), (ii) or (iii), constituting a “Material Adverse Effect”).

ARTICLE 3

REPRESENTATIONS AND COVENANTS OF PURCHASER

3.1.         The PURCHASER hereby represents and warrants that:

(a)          PURCHASER acknowledges that it has been provided with, and has carefully read, the Certificate of Designation attached hereto as Exhibit A, which describes all of the rights and other features of the Preferred Shares. Although I have been given a copy of the SELLER’S Registration Statement on Form S-1 filed with the SEC. I had a pre-existing relationship with the SELLER and did not learn of the SELLER through this filing with the SEC. PURCHASER and its representatives have had the opportunity to meet with or talk with representatives of SELLER and have had the opportunity to ask questions of, and receive answers from, representatives of SELLER concerning SELLER, and the terms and conditions of this transaction, as well as to obtain any information requested by PURCHASER. PURCHASER believes that any questions raised by PURCHASER or its representatives have been answered to the satisfaction of PURCHASER and its representatives. PURCHASER’s decision to purchase the Preferred Shares is based, in part, on the answers to such questions as PURCHASER and its representatives have raised concerning the transaction, and is based in part on its own evaluation of the risks and merits of the purchase and SELLER’s proposed business activities.

3.2.          PURCHASER has been advised that the Preferred Shares have not been registered under the 1933 Act, or qualified under the securities law of any state, on the ground, among others, that no distribution or public offering of the Preferred Shares is to be effected and the Preferred Shares will be issued by SELLER in connection with a transaction that does not involve any public offering within the meaning of section 4(a)(2) of the Act and/or Rule 506 of Regulation D as promulgated by the SEC under the 1933 Act, and under any applicable state blue sky authority. PURCHASER understands that SELLER is relying in part on PURCHASER's representations as set forth herein for purposes of claiming such exemptions and that the basis for such exemptions may not be present if, notwithstanding PURCHASER's representations, PURCHASER has in mind merely acquiring Shares for resale on the occurrence or nonoccurrence of some predetermined event. PURCHASER has no such intention.

3.3.          PURCHASER acknowledges that the securities underlying the Preferred Shares will be "restricted securities" (as such term is defined in Rule 144 promulgated under the 1933Act ("Rule 144")), that the securities underlying the Preferred Shares will include the foregoing restrictive legend, and, except as otherwise set forth in this Agreement, that the securities underlying the Preferred Shares cannot be sold for a period of one year, notwithstanding other restrictions that apply to the Preferred Shares as more fully set forth in this Agreement, from the date of issuance unless registered with the SEC and qualified by appropriate state securities regulators, or unless PURCHASER obtains written consent from the SELLER and otherwise complies with an exemption from such registration and qualification (including, without limitation, compliance with Rule 144).

3.4.          The PURCHASER has the full right, power and authority to enter into this Agreement and to carry out and consummate the transaction contemplated herein. This Agreement constitutes the legal, valid and binding obligation of PURCHASER.

3.5.          The PURCHASER acknowledges that investment in the Preferred Shares involves substantial risks and is suitable only for persons of adequate financial means who can bear the economic risk of an investment in the Preferred Shares for an indefinite period of time. PURCHASER further represents that he or she:

(1)         has adequate means of providing for his or her current needs and possible personal contingencies, has no need for liquidity in his or her investment in the Preferred Shares, is able to bear the substantial economic risks of an investment in the Preferred Shares for an indefinite period, and, at the present time, can afford a complete loss of his investment;

(2)         does not have an overall commitment to investments which are not readily marketable that is disproportionate to his or her net worth, and that his or her investment in the Preferred Shares will not cause such overall commitment to become excessive;

(3)         is acquiring the Preferred Shares for his or her own account, for investment purposes only and not with a view toward resale, assignment or distribution thereof, and no other person has a direct or indirect, beneficial interest, in whole or in part, in such Preferred Shares;

(4)         has such knowledge and experience in financial, tax and business matters that he or she is capable of evaluating the merits and risks of an investment in the Preferred Shares; and

(5)         has been given the opportunity to ask questions of and to receive answers from persons acting on the SELLER’S behalf concerning the terms and conditions of this transaction and also has been given the opportunity to obtain any additional information which the SELLER possesses or can acquire without unreasonable effort or expense. As a result, PURCHASER has available sufficient information concerning the affairs of the SELLER and has been able to evaluate the merits and risks of the investment in the Preferred Shares.

ARTICLE 4

AMENDMENT AND WAIVER

4.1           Waiver and Amendment. Any term, provision, covenant, representation, warranty or condition of this Agreement may be waived, but only by a written instrument signed by the party entitled to the benefits thereof. The failure or delay of any party at any time or times to require performance of any provision hereof or to exercise its rights with respect to any provision hereof shall in no manner operate as a waiver of or affect such party's right at a later time to enforce the same. No waiver by any party of any condition, or of the breach of any term, provision, covenant, representation or warranty contained in this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such condition or breach or waiver of any other condition or of the breach of any other term, provision, covenant, representation or warranty.

PURCHASER understands that the Company is relying in part on PURCHASER's representations as set forth herein for purposes of claiming such exemptions and that the basis for such exemptions may not be present if, notwithstanding PURCHASER's representations, PURCHASER has in mind merely acquiring Shares for resale on the occurrence or nonoccurrence of some predetermined event. PURCHASER has no such intention.

(b)          PURCHASER acknowledges that the securities underlying the Shares will be "restricted securities" (as such term is defined in Rule 144 promulgated under the Securities Act of 1933, as amended ("Rule 144")), that the securities underlying the Shares will include the foregoing restrictive legend, and, except as otherwise set forth in this Agreement, that the securities underlying the Shares cannot be sold for a period of one year, notwithstanding other restrictions that apply to the Shares as more fully set forth in this Agreement, from the date of issuance unless registered with the SEC and qualified by appropriate state securities regulators, or unless PURCHASER obtains written consent from the SELLER and otherwise complies with an exemption from such registration and qualification (including, without limitation, compliance with Rule 144).

(c)          The PURCHASER has the full right, power and authority to enter into this Agreement and to carry out and consummate the transaction contemplated herein. This Agreement constitutes the legal, valid and binding obligation of PURCHASER.

(d)          The PURCHASER acknowledges that investment in the Shares involves substantial risks and is suitable only for persons of adequate financial means who can bear the economic risk of an investment in the Shares for an indefinite period of time. PURCHASER further represents that he or she:

(1)         has adequate means of providing for his or her current needs and possible personal contingencies, has no need for liquidity in his or her investment in the Shares, is able to bear the substantial economic risks of an investment in the Shares for an indefinite period, and, at the present time, can afford a complete loss of his investment;

(2)         does not have an overall commitment to investments which are not readily marketable that is disproportionate to his or her net worth, and that his or her investment in the Shares will not cause such overall commitment to become excessive;

(3)         is acquiring the Shares for his or her own account, for investment purposes only and not with a view toward resale, assignment or distribution thereof, and no other person has a direct or indirect, beneficial interest, in whole or in part, in such Shares;

(4)         has such knowledge and experience in financial, tax and business matters that he or she is capable of evaluating the merits and risks of an investment in the Shares; and

(5)         has been given the opportunity to ask questions of and to receive answers from persons acting on each of the SELLERS' behalf concerning the terms and conditions of this transaction and also has been given the opportunity to obtain any additional information which each of the SELLERS possess or can acquire without unreasonable effort or expense. As a result, PURCHASER has available sufficient information concerning the affairs of the SELLER and has been able to evaluate the merits and risks of the investment in the Shares.
