If any provision of this Agreement is prohibited by law or otherwise determined to be invalid or unenforceable by a court of competent jurisdiction, the provision that would otherwise be prohibited, invalid or unenforceable shall be deemed amended to apply to the broadest extent that it would be valid and enforceable, and the invalidity or unenforceability of such provision shall not affect the validity of the remaining provisions of this Agreement so long as this Agreement as so modified continues to express, without material change, the original intentions of the parties as to the subject matter hereof and the prohibited nature, invalidity or unenforceability of the provision(s) in question does not substantially impair the respective expectations or reciprocal obligations of the parties or the practical realization of the benefits that would otherwise be conferred upon the parties. The parties will endeavor in good faith negotiations to replace the prohibited, invalid or unenforceable provision(s) with a valid provision(s), the effect of which comes as close as possible to that of the prohibited, invalid or unenforceable provision(s).

(d) Governing Law; Jurisdiction; Jury Trial. All questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by the internal laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdictions) that would cause the application of the laws of any jurisdictions other than the State of New York. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of New York, Borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY DISPUTE HEREUNDER OR IN CONNECTION WITH OR ARISING OUT OF THIS AGREEMENT OR ANY TRANSACTION CONTEMPLATED HEREBY.

(g) No Strict Construction. The language used in this Agreement will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction will be applied against any party.

(h) Entire Agreement; Effect on Prior Agreements; Amendments. Except for the Transaction Documents (to the extent any such Transaction Document in effect prior to this Agreement is not amended by this Agreement), this Agreement supersedes all other prior oral or written agreements between the Investor, the Company, their affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Agreement and the instruments referenced herein contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither the Company nor the Investor makes any representation, warranty, covenant or undertaking with respect to such matters. No provision of this Agreement may be amended other than by an instrument in writing signed by the Company and the Investor. No provision hereof may be waived other than by an instrument in writing signed by the party against whom enforcement is sought. The Company has not, directly or indirectly, made any agreements with any of the Buyers of Series A Warrants and Series B Warrants listed in the Existing Securities Purchase Agreement relating to the terms or conditions of the transactions contemplated by this Agreement on terms more favorable, in form or substance, than those offered in this Agreement. The Company hereby represents and warrants as of the date hereof and covenants and agrees from and after the date hereof until the expiration of forty-five (45) days from the Closing, that none of the terms offered to any other holder of the Investor Warrants relating to the exchange, amendment or early exercise thereof (the “Future Warrant Agreement”) is or will be more favorable to such person than those provided to the Investor and this Agreement shall be, without any further action by Investor or Company, deemed amended and modified in an economically and legally equivalent manner such that the Investor shall receive the benefit of the more favorable terms contained in such Future Warrant Agreement and issued and/or paid any such more favorable consideration.

EXCHANGE AGREEMENT

DISCLOSURE SCHEDULE

Schedule 2(b)(v)

On July 2, 2010, AMEX notified the Company that the Company was not in compliance with AMEX’s continued listing standards for the three month period ended March 31, 2010, because the Company’s stockholders’ equity was less than $6,000,000 and the Company had experienced losses from continuing operations and net losses in its five most recent fiscal years. The Company’s trading symbol has been appended with the indicator (.BC) to signify such noncompliance for trades reported on the "consolidated tape," which is an electronic service that provides last sale and trade data throughout the day for stocks listed on exchanges.

On August 2, 2010, the Company submitted a plan to regain compliance with Section 1003(a)(iii) of the Company Guide. On October 5, 2010, NYSE Amex notified us that it had accepted our plan and had granted an extension until March 31, 2011, for continued listing of our common stock and for us to regain compliance with the continued listing standards.
