This Note may not be prepaid in whole or in part except as otherwise provided herein. Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a Business Day (as defined below), the same shall instead be due on the next succeeding day which is a Business Day.

For purposes hereof the following terms shall have the meanings ascribed to them below:

“Business Day” shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the City of New York are authorized or required by law or executive order to remain closed.

“Conversion Price” shall be equal to the lower of $.002 or 50% of the lowest trading price of the Company’s common stock during the 20 consecutive trading days prior to the date on which Holder elects to convert all or part of the Note. If the Company is placed on “chilled” status with the Depository Trust Company (“DTC”), the discount shall be increased by 10% until such chill is remedied. If the Company is not Deposits and Withdrawal at Custodian (“DWAC”) eligible through their Transfer Agent and the Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer (“FAST”) system, the discount will be increased by 5%. In the case of both, the discount shall be a cumulative 15%.

(i) Stock Certificates or DWAC. The Company will deliver to the Holder, or Holder’s authorized designee, no later than two 2 Trading Days after the Conversion Date, a certificate or certificates (which certificate(s) shall be free of restrictive legends and trading restrictions) representing the number of shares of Common Stock being acquired upon the conversion of this Note. In lieu of delivering physical certificates representing the shares of Common Stock issuable upon conversion of this Note, provided the Company’s transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon request of the Holder, the Company shall use commercially reasonable efforts to cause its transfer agent to electronically transmit such shares issuable upon conversion to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) prime broker with DTC through its Deposits and Withdrawal at Custodian (“DWAC”) program (provided that the same time periods herein as for stock certificates shall apply).

(ii) Charges, Expenses. Issuance of Common Stock to Holder, or any of its assignees, upon the conversion of this Note shall be made without charge to the Holder for any issuance fee, transfer tax, postage/mailing charge or any other expense with respect to the issuance of such Common Stock. Company shall pay all Transfer Agent fees incurred from the issuance of the Common stock to Holder and acknowledges that this is a material obligation of this Note.

If the Company fails to deliver to the Holder such certificate or certificates (or shares through DTC) pursuant to this Section (free of any restrictions on transfer or legends) prior to 3 Trading Days after the Conversion Date, the Company shall pay to the Holder as liquidated damages an amount equal to $2,000 per day, until such certificate or certificates are delivered. The Company acknowledges that it would be extremely difficult or impracticable to determine the Holder’s actual damages and costs resulting from a failure to deliver the Common Stock and the inclusion herein of any such additional amounts are the agreed upon liquidated damages representing a reasonable estimate of those damages and costs. Such liquidated damages will be automatically added to the Principal Amount of the Note.

(c) Reservation and Issuance of Underlying Securities. The Company covenants that it will at all times reserve and keep available out of its authorized and unissued Common Stock solely for the purpose of issuance upon conversion of this Note (and repayments in Common Stock), free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder, not less than three times the number of shares of Common Stock as shall be issuable (taking into account the adjustments under this Section 1 but without regard to any ownership limitations contained herein) upon the conversion of this Note to Common Stock (the “Required Reserve”). The Company covenants that all shares of Common Stock that shall be issuable will, upon issue, be duly authorized, validly issued, fully-paid, non-assessable and freely-tradable. If the amount of shares on reserve at the Transfer Agent for this Note in Holder’s name shall drop below the Required Reserve, the Company will, within two (2) business days of written notification from Holder, instruct the Transfer Agent to increase the number of shares so that the Required Reserve is met. The Company agrees that this is a material term of this Note and any breach of this will result in a default of the Note.

(d) Conversion Limitation. The Holder will not submit a conversion to the Company that would result in the Holder owning more than 9.99% of the then total outstanding shares of the Company (“Restricted Ownership Percentage”).

The Company acknowledges that it would be extremely difficult or impracticable to determine the Holder’s actual damages and costs resulting from an Event of Default and any such additional amounts are the agreed upon liquidated damages representing a reasonable estimate of those damages and costs. The remedies under this Note shall be cumulative and automatically added to the principal value of the Note.
