This Note is subject to the following additional provisions:

1. This Note is exchangeable for an equal aggregate principal amount of Notes of different authorized denominations, as requested by the Holder surrendering the same. No service charge will be made for such registration or transfer or exchange, except that Holder shall pay any tax or other governmental charges payable in connection therewith. To the extent that Holder subsequently transfers, assigns, sells or exchanges any of the multiple lesser denomination notes, Holder acknowledges that it will provide the Company with Opinions of Counsel as provided for in Section 2(f) of the Securities Purchase Agreement.

2. The Company shall be entitled to withhold from all payments any amounts required to be withheld under applicable laws.

3. This Note may be transferred or exchanged only in compliance with the Securities Act of 1933, as amended (“Act”), applicable state securities laws and Sections 2(f) and 5(f) of the Securities Purchase Agreement. Any attempted transfer to a non-qualifying party shall be treated by the Company as void. Prior to due presentment for transfer of this Note, the Company and any agent of the Company may treat the person in whose name this Note is duly registered on the Company’s records as the owner hereof for all other purposes, whether or not this Note be overdue, and neither the Company nor any such agent shall be affected or bound by notice to the contrary. Any Holder of this Note electing to exercise the right of conversion set forth in Section 4(a) hereof, in addition to the requirements set forth in Section 4(a), and any prequalified prospective transferee of this Note, also is required to give the Company written confirmation that this Note is being converted (“Notice of Conversion”) in the form annexed hereto as Exhibit A. The date of receipt (including receipt by telecopy) of such Notice of Conversion shall be the Conversion Date. All notices of conversion will be accompanied by an Opinion of Counsel.

4. (a) The Holder of this Note is entitled, at its option, at any time after 180 days, to convert all or any amount of the principal face amount of this Note then outstanding into shares of the Company’s common stock (the “Common Stock”) at a price (“Conversion Price”) for each share of Common Stock equal to 50% of the lowest closing bid price of the Common Stock as reported on the National Quotations Bureau OTCQB exchange which the Company’s shares are traded or any exchange upon which the Common Stock may be traded in the future (“Exchange”), for the lower of (i) twenty prior trading days immediately preceding the issuance date of this note or (ii) the twenty prior trading days including the day upon which a Notice of Conversion is received by the Company or its transfer agent (provided such Notice of Conversion is delivered together with an Opinion of Counsel, by fax or other electronic method of communication to the Company after 4 P.M. Eastern Standard or Daylight Savings Time if the Holder wishes to include the same day closing price). If the shares have not been delivered within 3 business days, the Notice of Conversion may be rescinded. Such conversion shall be effectuated by the Company delivering the shares of Common Stock to the Holder within 3 business days of receipt by the Company of the Notice of Conversion. Accrued, but unpaid interest shall be subject to conversion. No fractional shares or scrip representing fractions of shares will be issued on conversion, but the number of shares issuable shall be rounded to the nearest whole share. To the extent the Conversion Price of the Company’s Common Stock closes below the par value per share, the Company will take all steps necessary to solicit the consent of the stockholders to reduce the par value to the lowest value possible under law. The Company agrees to honor all conversions submitted pending this increase. In the event the Company experiences a DTC “Chill” on its shares, the conversion price shall be decreased to 40% instead of 50% while that “Chill” is in effect. In no event shall the Holder be allowed to effect a conversion if such conversion, along with all other shares of Company Common Stock beneficially owned by the Holder and its affiliates would exceed 9.9% of the outstanding shares of the Common Stock of the Company.

The dollar amount converted into Interest Shares shall be all or a portion of the accrued interest calculated on the unpaid principal balance of this Note to the date of such notice.

(c) This Note may not be prepaid, except that if the $68,000 Rule 144 convertible redeemable note issued by the Company of even date herewith is redeemed by the Company within 6 months of the issuance date of such Note, all obligations of the Company under this Note and all obligations of the Holder under the Holder issued Back End Note will be automatically be deemed satisfied and this Note and the Holder issued Back End Note will be automatically be deemed cancelled and of no further force or effect.

(e) In case of any Sale Event (not to include a sale of all or substantially all of the Company’s assets) in connection with which this Note is not redeemed or converted, the Company shall cause effective provision to be made so that the Holder of this Note shall have the right thereafter, by converting this Note, to purchase or convert this Note into the kind and number of shares of stock or other securities or property (including cash) receivable upon such reclassification, capital reorganization or other change, consolidation or merger by a holder of the number of shares of Common Stock that could have been purchased upon exercise of the Note and at the same Conversion Price, as defined in this Note, immediately prior to such Sale Event.
