This Note shall be binding upon the Company and its successors and permitted assigns and shall inure to the benefit of the Holder and its successors and assigns.  The Company may not assign or delegate any of its duties or obligations under this Note without the written consent of the Holder.  This Note is one of a series of 10% convertible promissory notes of like tenor and ranking made by the Company in favor of certain investors and issued, from time to time (collectively, the Notes) pursuant to that certain Securities Purchase Agreement by and between the Company and certain investors, including the Holder, of even date herewith (the Securities Purchase Agreement).  Each of the Notes shall rank equally without preference or priority of any kind over one another, and all payments on account of principal and interest with respect to any of the Notes shall be applied ratably and proportionately on the outstanding Notes on the basis of the principal amount of the outstanding indebtedness represented thereby.  1. Maturity.  Unless otherwise converted into Preferred Stock, as hereinafter defined, this Note shall mature on July 31, 2011 (such date, the Maturity Date).  On the Maturity Date, unless, and to the extent, converted into Preferred Stock, any and all outstanding principal and Interest due and owing under the Note shall be immediately paid by the Company.  2. Conversion.  (a) General. The entire Principal Amount of this Note, along with all accrued Interest thereon, shall, at the option of the Holder, be convertible at any time prior to the Maturity Date into the Companys Series A Convertible Redeemable Preferred Stock (Preferred Stock) at a conversion price (the Conversion Price) equal to $30.00 per share of Preferred Stock.  To exercise such optional conversion, Holder must complete the attached Optional Conversion Notice Addendum (the Addendum), and deliver the original of this Note (or an affidavit of loss reasonably acceptable to the Company) and the executed Addendum to the Company on or before that date that is within 10 business days following the Maturity Date.  Subject to the terms below, the conversion will be effective two (2) business days following the Companys receipt of the original of this Note and the Addendum.  If such conversion is effected in connection with an offering (the Next Round Financing) of Preferred Stock by the Company, the Preferred Stock issued to the Holder shall have rights, preferences, privileges and restrictions (including, without limitation, registration rights, preemptive rights and any other contractual rights) identical to those granted to or received by the other investors in the Next Round Financing.

Holder shall not be entitled to vote or receive distributions or be deemed the holder of Preferred Stock or any other securities of the Company which may at any time be issuable upon the conversion of this Note for any purpose, nor shall anything contained herein be construed to confer upon Holder, as such, any of the rights of a stockholder of the Company or any right to vote as a stockholder of the Company or upon any matter submitted to stockholders at any meeting thereof, or to give or withhold consent to any corporate action (whether upon any recapitalization, issuance of equity securities of the Company, reclassification of equity securities of the Company, consolidation, merger, transfer of assets or otherwise) or to receive notice of meetings, or to receive distributions or subscription rights or otherwise unless and until this Note is converted in accordance with the terms hereof.  (c) Reservation of Preferred Stock. The Company shall reserve and keep available out of its authorized but unissued shares of Preferred Stock, solely for the purpose of conversion of this Note, that number of shares of Preferred Stock equal to the number of shares of Preferred Stock into which the Note is convertible based upon the Conversion Price.  3.

Any adjustment made pursuant to this Section 3(a) shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.  (b) Mergers, Consolidations, Etc.
