Capitalized terms used and not otherwise immediately defined are defined in Section 9 below.

1.

Designation, Amount and Par Value.  The series of Preferred Stock shall be designated as the "Series B Convertible Preferred Stock" (the "Series B Preferred Stock") and the number of shares so designated shall be Three Thousand Six Hundred Eight-Three (3,683).

2

Stated Value; Dividends.

a.

Stated Value.  The par value of each issued share of Series B Preferred Stock shall be $0.001 per share, and the stated value of each issued share of Series B Preferred Stock shall be deemed to be Ninety One Dollars and Forty One Cents ($91.41) (the "Stated Value").

b.

Dividends.  The Holders of Series B Preferred Stock shall be entitled to receive dividends and other distributions when, as and if declared by the Board of Directors out of funds legally available for such purposes. If at any time the Corporation declares any dividend or other distribution on the Common Stock or any other Junior Security and there are shares of its Series B Preferred Stock issued and outstanding, then a dividend or other distribution shall also be declared on the Series B Preferred Stock payable prior to the dividend or other distribution on the Common Stock or any other Junior Security, entitling each Holder of Series B Preferred Stock to receive the dividend or distribution such holder would have received had such holder converted the Series B Preferred Stock into Conversion Shares as of the record date for determining shareholders entitled to receive such dividend or distribution.

Dividends shall be payable to Holders of record, as they appear on the stock books of the Corporation on such record dates as may be declared by the Board of Directors, not more than sixty (60) days, nor less than ten (10) days preceding the payment dates of such dividends. If the dividend on the Series B Preferred Stock shall not have been paid or set apart in full for the Series B Preferred Stock when payable, the aggregate deficiency shall be cumulative and shall be fully paid or set apart for payment before any dividends shall be paid upon or set apart for, or any other distributions paid made on, or any payments made on account of the purchase, redemption or retirement of, the Common Stock or any other Junior Security. When dividends are not paid in full upon the shares or fractions of a share of Series B Preferred Stock and any shares pari passu with the Series B Preferred Stock, all dividends declared upon this Series Bnd any other shares pari passu with the Series B Preferred Stock shall be declared, pro rata, so that the amount of dividends declared per share or fraction of a share on this Series B Preferred Stock and such other shares pari passu with the Series B Preferred Stock shall in all cases bear to each other the same rates that accrued dividends per share on the shares of Series B Preferred Stock and such other shares pari passu with the Series B Preferred Stock bear to each other.

3.

Voting Rights.  Except as otherwise required by law, each Holder of the shares of Series B Preferred Stock shall have no voting rights.

If the holder chooses to exercise its option to convert the Series B Preferred Stock prior to the one (1) year anniversary of the Original Issue Date, then such conversion must be approved by written consent of the Board of Directors of the Company. The "Series B Conversion Price" shall initially be $0.0000102796985970042 per share; provided, however that the Series B Conversion Price, and the rate at which shares of Series B Preferred Stock may be converted into shares of Common Stock, shall be subject to adjustment as provided in Section 6 below.

Each Notice of Conversion shall specify the number of shares of Series B Preferred Stock to be converted, the number of shares of Series B Preferred Stock owned prior to the conversion at issue, the number of shares of Series B Preferred Stock owned subsequent to the conversion at issue and the date on which such conversion is to be effected, which date may not be prior to the date the applicable Holder delivers by facsimile such Notice of Conversion to the Corporation (such date, the "Conversion Date"). If no Conversion Date is specified in a Notice of Conversion, the Conversion Date shall be the date that such Notice of Conversion to the Corporation is deemed delivered hereunder.

In lieu of any fractional shares to which the holder would otherwise be entitled, the Corporation shall pay cash equal to such fraction multiplied by the fair market value of a share of Common Stock as determined in good faith by the Board of Directors, or round-up to the next whole number of shares of Common Stock, at the Corporation's option. Whether or not fractional shares would be issuable upon such conversion shall be determined on the basis of the total number of shares of Series B Preferred Stock the Holder is at the time converting into Common Stock and the aggregate number of shares of Common Stock issuable upon such conversion.

e.

Reservation of Shares Issuable Upon Conversion.  The Corporation covenants that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of the Series B Preferred Stock, free from preemptive rights or any other actual contingent purchase rights of Persons other than the Holders of the Series B Preferred Stock, not less than such aggregate number of shares of the Common Stock as shall be issuable upon the conversion of all outstanding shares of Series B Preferred Stock. The Corporation covenants that all shares of Common Stock that shall be so issuable shall, upon issue, be duly authorized, validly issued, fully paid and nonassessable.

(ii)

additional stock or other securities or property (other than cash in respect of which shall be covered by the terms of Section 3(c) above) by way of spin-off, split-up, reclassification, combination of shares or similar corporate rearrangement (other than shares of Common Stock issued as a stock split or adjustments in respect of which shall be covered by the terms of Section 6(a) above), then and in each such case, the Series B Conversion Price shall be adjusted proportionately, and the Holder hereof shall, upon the conversion of the Series B Preferred Stock, be entitled to receive, in addition to the number of shares of Common Stock receivable thereupon, and without payment of any additional consideration therefor, the amount of stock and other securities and property that such Holder would hold on the date of such exercise had such Holder been the holder of record of such Common Stock as of the date on which holders of Common Stock received or became entitled to receive such shares or all other additional stock and other securities and property. The Series B Conversion Price, as so adjusted, shall be readjusted in the same manner upon the happening of any successive event or events described in this Section 6(b).

c.

Reorganization. Reclassification, Consolidation. Merger or Sale.  At any time while the Series B Preferred Stock is outstanding, if any recapitalization, reclassification or reorganization of the capital stock of the Corporation, or any consolidation or merger of the Corporation with another corporation, or the sale of all or substantially all of its assets or other transaction shall be effected in such a way that holders of Common Stock shall be entitled to receive stock, securities or other assets or property (an "Organic Change"), then lawful and adequate provisions shall be made by the Corporation whereby the Holders shall thereafter have the right to purchase and receive (in lieu of the shares of the Common Stock of the Corporation immediately theretofore purchasable and receivable upon the conversion of the Series B Preferred Stock) such shares of stock, securities or other assets or property as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable assuming the full conversion of the Series B Preferred Stock. In the event of any Organic Change, appropriate provision shall be made by the Corporation with respect to the rights and interests of the Holders to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Series B Conversion Price) shall thereafter be applicable, in relation to any shares of stock, securities or assets thereafter deliverable upon the conversion thereof.

Price be reduced below the par value of the Common Stock. Upon each such adjustment of the Series B Conversion Price hereunder, the number of Conversion Shares issuable upon conversion of this Note shall be adjusted to the number of shares determined by multiplying the Series B Conversion Price in effect immediately prior to such adjustment by the number of Conversion Shares issuable upon conversion immediately prior to such adjustment and dividing the product thereof by the Series B Conversion Price resulting from such adjustment.

Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 6(d) in respect of an Exempt Issuance. The Corporation shall notify the Holder in writing, no later than the third (3rd) Trading Day following the issuance of any Common Stock or Common Stock Equivalent subject to this section, indicating therein the applicable issuance price, or of applicable reset price, exchange price, conversion price and other pricing terms.

Notwithstanding anything to the contrary contained herein, any good faith issuance of shares of Common Stock issued or issuable to any employees, officers or directors of the Company pursuant to stock grants, option plans, purchase plans, or other employees stock incentive programs or arrangements approved by the Board of Directors, or upon any subsequent exercise of options or warrants granted to such parties pursuant to any such plan or arrangement shall not be deemed a Dilutive Issuance.

e.

Subsequent Rights Offerings.  If the Corporation, at any time while the Series B Preferred Stock is outstanding, shall issue rights, options or warrants to all holders of Common Stock (and not to the Holders) entitling them to subscribe for or purchase shares of Common Stock at a price per share less than the VWAP as of the record date mentioned below, then the Series B Conversion Price shall be reduced, concurrently with such issue, to a price (calculated to the nearest cent) determined by multiplying such Series B Conversion Price by a fraction, (A) the numerator of which shall be (1) the number of shares of Common Stock outstanding immediately prior to such issue plus (2) the number of shares of Common Stock which the aggregate consideration received or to be received by the Corporation for the total number of additional shares of Common Stock so issued would purchase at such VWAP; and (B) the denominator of which shall be the number of shares of Common Stock outstanding immediately prior to such issue plus the number of such additional shares of Common Stock so issued; provided that, (i) for the purpose of this Section 6(e), all shares of Common Stock issuable upon conversion or exchange of convertible securities outstanding immediately prior to such issue shall be deemed to be outstanding, and (ii) the number of shares of Common Stock deemed issuable upon conversion or exchange of such outstanding convertible securities shall be determined without giving effect to any adjustments to the conversion or exchange price or conversion or exchange rate of such convertible securities resulting from the issuance of rights, options or warrants that is the subject of this calculation. Such adjustment shall be made whenever such rights, options or warrants are issued, and shall become effective immediately after the record date for the determination of shareholders entitled to receive such rights, options or warrants.

f.
