(c)         No Conflicts.  The execution, delivery and performance of this Agreement by the Company and the consummation by the Company of the transactions contemplated hereby do not and will not: (i) conflict with or violate any provision of the Company’s or any of its subsidiaries’ certificate or articles of incorporation, bylaws or other organizational or charter documents, or (ii) conflict with, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, result in the creation of any lien upon any of the properties or assets of the Company or any subsidiary, or give to others any rights of termination, amendment, acceleration or cancellation (with or without notice, lapse of time or both) of, any material agreement, credit facility, debt or other material instrument (evidencing a Company or subsidiary debt or otherwise) or other material understanding to which the Company or any subsidiary is a party or by which any property or asset of the Company or any subsidiary is bound or affected, or (iii) conflict with or result in a violation of any law, rule, regulation, order, judgment, injunction, decree or other restriction of any court or governmental authority to which the Company or a subsidiary is subject (including federal and state securities laws and regulations), or by which any property or asset of the Company or a subsidiary is bound or affected; except in the case of each of clauses (ii) and (iii), such as could not have or reasonably be expected to result in a Material Adverse Effect.
 
(d)        Issuance of the Securities.  The shares of Series F-1 Preferred Stock are duly authorized and, when issued in accordance with this Agreement, will be duly and validly issued, fully paid and nonassessable, free and clear of all liens imposed by the Company.  The Underlying Shares, when issued in accordance with the terms of the Transaction Documents, will be validly issued, fully paid and nonassessable, free and clear of all liens imposed by the Company other than restrictions on transfer provided for in the Transaction Documents.  The Company has reserved from its duly authorized capital stock a sufficient number of shares of Common Stock for issuance of all of the Underlying Shares.
 
(e)         Filings, Consents and Approvals.  The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority or other person in connection with the execution, delivery and performance by the Company of the Transaction Documents, other than: (i) the filings required pursuant to Sections 5 and 8(a) of this Agreement, (ii) the filing of the Series F-1 Certificate of Designation with the Delaware Secretary of State, and (iii) filings in certain states under “blue sky” laws (collectively, the “Required Approvals”).

4.          Representations and Warranties of the Holder.  The Holder hereby represents and warrants as of the date hereof to the Company as follows (unless as of a specific date therein):

(a)        Organization; Authority.  The Holder is an individual with the authority to enter into and to consummate the transactions contemplated by this Agreement and otherwise to carry out the obligations hereunder and thereunder. This Agreement has been duly executed by the Holder, and when delivered by the Holder in accordance with the terms hereof, will constitute the valid and legally binding obligation of the Holder, enforceable in accordance with its terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law.

(b)        Holder Status.  At the time the Holder was offered the Securities, he was, and as of the date hereof is, an “accredited investor” as defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities Act.

The Company acknowledges and agrees that the representations contained in Section 3 shall not modify, amend or affect the Holder’s right to rely on the Company’s representations and warranties contained in this Agreement or any other document or instrument executed and/or delivered in connection with this Agreement or the consummation of the transaction contemplated hereby.

8.           Miscellaneous.

(a)         The Company shall by 9:00 a.m. (New York City time) within four days of the trading day immediately following the date hereof file a Current Report on Form 8-K with the Securities and Exchange Commission disclosing the material terms of the transactions contemplated hereby, and shall attach this Agreement as an exhibit thereto.

(b)        This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and shall become effective when counterparts have been signed by each party and delivered to the other parties hereto, it being understood that all parties need not sign the same counterpart. Signature pages to this Agreement may be delivered by facsimile or other means of electronic transmission.

(c)          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)      Except as expressly set forth herein, all of the terms and conditions of the Purchase Agreement and the Transaction Documents (as such term is defined in the Purchase Agreement) shall continue in full force and effect after the execution of this Agreement and shall not be in any way changed, modified or superseded by the terms set forth herein.
 
(e)         This Agreement shall be governed by and construed in accordance with the internal laws of the State of New York, without giving effect to any of the conflicts of law principles that would result in the application of the substantive law of another jurisdiction.
