Payment due on any date that is not a business day at the Payor's principal place of business shall be due and payable on the next business day.
  1.            Upon an Event of Default (as defined below) or after October 30, 2010, interest shall accrue on this Note until payment in full thereof, both before and after judgment, at a rate equal to eight percent (8%) per annum.
  2.            Each of the following shall constitute an Event of Default: (a) Payor's failure to pay the full principal amount and accrued but unpaid interest or any other amount payable hereunder when the same shall become due and payable; (b) the filing of any petition in bankruptcy against Payor or the appointment of a receiver or trustee in bankruptcy for Payor or the initiation of a similar proceeding against Payor, and the failure of Payor to cause such proceeding to be dismissed within 60 days thereafter; (c) the filing of any petition in bankruptcy by Payor; (d) Payor shall admit in writing its inability, or shall fail generally, to pay debts as they become due; or (e) Payor shall fail to perform any term, covenant, condition or agreement contained in this Note or any agreement or instrument executed by Payor in connection with this Note.

At any time on or after the date of issuance of this Note and on or prior to the date of the payment in full thereof, Holder may, by written notice to the Company, convert the outstanding principal balance and all unpaid accrued interest into the number of shares of Common Stock, par value $0.001 per share ("Common Stock") of the Company equal to (i) the outstanding principal balance and all unpaid accrued interest of this Note, divided by (ii) $0.40 (as adjusted for any Common Stock splits, stock dividends, recapitalizations, combinations or the like). The Company shall not issue fractional shares, and any unconverted amounts resulting shall be paid at the time of such conversion.
  4.           All payments of interest and principal shall be in lawful money of the United States of America. All payments shall be applied first to accrued interest, and thereafter to principal.
  5.            Payor may prepay this Note in full or in part without premium or penalty at any time after the date hereof and prior to the Maturity Date to Holder at the address set forth below. If prepaid in part, Payor shall first pay all accrued unpaid interest on and then principal of the Note.
  6.           Payor hereby waives demand, notice presentment, protest and notice of dishonor.
  7.           The Company shall not, after the date hereof and until this Note is paid in full, issue any indebtedness, debentures, notes or other evidence of indebtedness that is or purports to be superior or senior in right of payment or priority to the indebtedness evidenced by this Note.
  8.            The Holder has the right to declare the entire unpaid principal and interest under this Note due immediately after an Event of Default by Payor in its payment obligations hereunder and upon thirty (30) days' written notice to the Payor.
