Subscriber hereby acknowledges and agrees to the entire terms of the Certificate of Designation, including, without limitation, the voting rights in Section 3 thereof, the restrictions on transfer of the Securities in Section 5 thereof and the redemption of the Securities pursuant to Section 6 thereof. The purchase price for the Securities will be paid by Subscriber to the Company in cash in the aggregate amount of One Hundred Dollars ($100).

2.

Voting Agreement. Subscriber agrees to (a) attend any meeting of the stockholders of the Company upon which the Authorized Stock Increase (as defined in the Certificate of Designation) is scheduled to be voted, (b) vote all Securities with regard to the Authorized Stock Increase in the manner set forth in the Certificate of Designation and (c) upon request by the Company, grant an irrevocable proxy to vote the Securities in accordance with the foregoing to a designee of the Company.

3.

Representations and Warranties of Subscriber. In consideration of the Company’s offer to sell the Securities, and in addition to the purchase price to be paid, Subscriber hereby covenants, represents and warrants to the Company as follows:

a.

Information About the Company. Subscriber has had an opportunity to ask questions of, and receive answers from, the Company concerning the business, management, and financial and compliance affairs of the Company and the terms and conditions of the purchase of the Securities contemplated hereby. Subscriber has had an opportunity to obtain, and has received, any additional information deemed necessary by Subscriber to verify such information in order to form a decision concerning an investment in the Company.

b.

Restrictions on Transfer. Subscriber covenants, represents and warrants that the Securities are being purchased for Subscriber’s own personal account and for Subscriber’s individual investment and without the intention of reselling or redistributing the same, that Subscriber has made no agreement with others regarding any of such Securities, and that Subscriber’s financial condition is such that it is not likely that it will be necessary to dispose of any of the Securities in the foreseeable future. Moreover, Subscriber acknowledges that any of the aforementioned actions may require the prior written consent of the Company’s board of directors pursuant to the Certificate of Designation. Subscriber is aware that, in the view of the Securities and Exchange Commission, a purchase of the Securities with an intent to resell by reason of any foreseeable specific contingency or anticipated change in market values, or any change in the condition of the Company, or in connection with a contemplated liquidation or settlement of any loan obtained by Subscriber for the acquisition of the Securities and for which the Securities were pledged as security, would represent an intent inconsistent with the covenants, warranties and representations set forth above. Subscriber understands that the Securities have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state or foreign securities laws in reliance on exemptions from registration under these laws, and that, accordingly, the Securities may not be resold by the undersigned (i) unless they are registered under both the Securities Act and applicable state or foreign securities laws or are sold in transactions which are exempt from, or not subject to, such registration, and (ii) except in compliance with Section 5 of the Certificate of Designation, which may require the prior written consent of the Company’s board of directors. Subscriber therefore agrees not to sell, assign, transfer or otherwise dispose of the Securities (i) unless a registration statement relating thereto has been duly filed and become effective under the Securities Act and applicable state or foreign securities laws, or unless in the opinion of counsel satisfactory to the Company no such registration is required under the circumstances, and (ii) except in compliance with Section 5 of the Certificate of Designation. There is not currently, and there will not in the future exist, a public market for the Securities; and accordingly, for the above and other reasons, Subscriber may not be able to liquidate an investment in the Securities for an indefinite period.

d.

High Degree of Economic Risk. Subscriber realizes that an investment in the Securities involves a high degree of economic risk to Subscriber, including the risks of receiving no return on the investment and/or of losing Subscriber’s entire investment in the Company. Subscriber is able to bear the economic risk of investment in the Securities, including the total loss of such investment. Subscriber understands that the Securities are subject to redemption at Subscriber’s aggregate purchase price as provided in the Certificate of Designation and accordingly should in no event expect to have any economic gain from its investment in the Securities.

e.

Suitability. Subscriber has such knowledge and experience in financial, legal and business matters that Subscriber is capable of evaluating the merits and risks of an investment in the Securities. Subscriber understands that no federal or state agency has made any finding or determination as to the fairness for investment, nor any recommendation or endorsement, of the Securities.

f.

Tax Liability. Subscriber will rely solely on its own advisors, and not on any statements or representations of the Company or any of its agents, representatives, employees, affiliates or subsidiaries, in respect of the federal, state, local and foreign tax consequences of this investment. Subscriber understands that Subscriber (and not the Company) shall be responsible for Subscriber’s own tax liability that may arise as a result of this investment or the transactions contemplated by this Agreement. Under penalties of perjury, Subscriber certifies that Subscriber is not subject to back-up withholding either because Subscriber has not been notified that Subscriber is subject to back-up withholding as a result of a failure to report all interest and dividends, or because the Internal Revenue Service has notified Subscriber that Subscriber is no longer subject to back-up withholding.

g.

Limitation Regarding Representations. Except as set forth in this Agreement, no covenants, representations or warranties have been made to Subscriber by the Company or any agent, representative, employee, director or affiliate or subsidiary of the Company and in entering into this transaction, Subscriber is not relying on any information, other than that contained herein and the results of independent investigation by Subscriber without any influence by Company or those acting on Company’s behalf. Subscriber agrees it is not relying on any oral or written information not expressly included in this Agreement, including but not limited to the information which has been provided by the Company, its directors, its officers or any affiliate or subsidiary of any of the foregoing.

h.

Authority. Subscriber is a natural person of legal age and capacity.

4.

The Securities represented hereby have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), and have not been registered under any state securities laws.

The expenses of Indemnitees must be paid by the Company or through insurance purchased and maintained by the Company or through other financial arrangements made by the Company, as such expenses are incurred and in advance of the final disposition of any Proceeding, upon receipt of an undertaking by or on behalf of such Indemnitee to repay the amount if it is ultimately determined by a court of competent jurisdiction that such Indemnitee is not entitled to be indemnified by the Company. To the extent that an Indemnitee is successful on the merits or otherwise in defense of any Proceeding, or in the defense of any claim, issue or matter therein, the Company shall indemnify such Indemnitee against expenses, including attorneys’ fees, actually and reasonably incurred in by such Indemnitee in connection with the defense.

11.

Modifications. This Agreement may not be changed, modified, released, discharged, abandoned or otherwise amended, in whole or in part, except by an instrument in writing, signed by Subscriber and the Company.
