        Company shall reserve and keep available out of its authorized but un-issued
        shares of Common Stock, solely for the purpose of effecting the conversion

| | c. | Mandatory Redemption. In the event that
        the Company shall merge into, be acquired by, or transfer a majority of
        its assets to any other company or individual buyer, then the Company
        shall, within thirty (30) days of the date the Company effects any of
        these events, redeem the entire outstanding convertible debenture at an
        amount equal to one hundred twenty percent (120%) of the amount redeemed
        plus accrued interest.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                         
| |    |                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                             
| | d. | Interest Payments. The interest so payable
        will be paid at the time of maturity or conversion to the person in whose
        name this Debenture is registered. At the time such interest is payable,
        the Holder, in its sole discretion, may elect to receive the interest
        in cash (via wire transfer or certified funds) or in the form of Common
        Stock. In the event of default, as described in Article III Section 3.01
        hereunder, the Holder may elect that the interest be paid in cash (via
        wire transfer or certified funds) or in the form of Common Stock. If paid
        in the form of Common Stock, the amount of stock to be issued will be
        calculated on the $0.50. A number of shares of Common Stock with a
        value equal to the amount of interest due shall be issued. No fractional
        shares will be issued; therefore, in the event that the value of the Common
        Stock per share does not equal the total interest due, the Company will
        pay the balance in cash.

---

| | e. | Paying Agent and Registrar. Initially,
        the Company will act as paying agent and registrar. The Company may change
        any paying agent, registrar, or Company-registrar by giving the Holder
        not less than ten (10) business days written notice of its election
        to do so, specifying the name, address, telephone number and facsimile
        number of the paying agent or registrar. The Company may act in any such
        capacity.

| | h. | Amendments and Waiver of Default.The
        Debenture may not be amended. Notwithstanding the above, without the consent
        of the Holder, the Debenture may be amended to cure any ambiguity, defect
