      FOR
        VALUE RECEIVED, the undersigned, DRTATTOFF, LLC (the "Company"), with its
        registered office in the state of California located at 8500 Wilshire Blvd
        Suite
        105, Beverly Hills, CA 90211 hereby promises to pay to the order of Christopher
        Knight or
        permitted assigns (the "Payee"), the principal amount of One
        Hundred and Thirty Eight
        Thousand
($138,000)
        (the
        "Principal Amount") with interest from the date hereof on the Principal Amount
        at the rate of five percent (5%) per annum. Interest on this Note shall be
        calculated based upon a year of 360 days. All payments of principal and interest
        shall be made in lawful money of the United States of America.

      

      In
        addition, the Company shall with 30 days of above date, assign 2.3%
        equity
        ownership stake in Company as per the terms of Company Operating
        Agreement.

      

      This
        Note is due and payable as follows: Nine
        Months
        from above date all Principal and all accrued but unpaid interest shall be
        due
        and payable in full. All payments hereunder shall be applied first to the
        payment of interest and then to the outstanding Principal Amount.

      

      Conversion.
        Upon the completion by the Company of a transaction, or series of related
        transactions, in which the Company sells equity securities resulting securities
        resulting in gross proceeds to the Company equal to or exceeding Two Million
        Dollars ($2,000,000) (excluding the aggregate amount of principal represented
        by
        the Notes) (a “Next
        Equity Financing”),
        before the Maturity Date, the outstanding Principal Amount and unpaid, accrued
        interest on this Note may be converted into fully paid and nonassessable
        shares
        of that type of the Company’s equity securities issued in the Next Equity
        Financing. The number of shares of such equity securities to be issued upon
        such
        conversion shall be equal to the quotient obtained by dividing (a) the aggregate
        outstanding Principal Amount and unpaid, accrued interest due on this Note
        on
        the date of conversion by (b) the price per share of such equity securities
        sold
        to the investors in the Next Equity Financing. The shares of equity securities
        to be issued upon conversion of this Note pursuant to this Section 4 shall
        be
        entitled to the same rights and subject to the same obligations provided
        in the
        purchase agreement entered into with investors in the Next Equity Financing.
        In
        conjunction with such conversion, the Holder shall become a party to and
        shall
        execute all related Next Equity Financing documentation, including, but not
        limited to, a definitive stock purchase agreement.
