At any time prior to the Maturity Date, the holders of the Notes can convert the principal amount of the Notes plus accrued and unpaid interest into shares of Series D Preferred Stock (or, if necessary under Delaware law, a new class of preferred stock having the same rights, preferences, and privileges as the Series D Preferred Stock) at a conversion price equal to $1.20 per share (as adjusted for stock splits, combinations, stock dividends and the like) of Series D Preferred Stock.

In the event that the holders of the Notes do not own Common Stock at the time of the conversion to Series D Preferred Stock pursuant to the Notes, then, in addition to the shares of Series D Preferred Stock issuable as stated above, the holders of the Notes shall receive 0.0342 shares of Series D Preferred Stock for each dollar of the Notes plus accrued and unpaid interest converted. Alternatively, in the event that the Company enters into an agreement to issue "Qualified Financing Securities" prior to the Maturity Date, then the holders of the Notes can convert the principal amount of the Notes plus accrued and unpaid interest into Qualified Financing Securities at a conversion price equal to the purchase price per Qualified Financing Security. A "Qualified Financing Security" means a security issued by the Company pursuant to an agreement executed after March 6, 2003 that provides the Company debt or equity financing in connection with the issuance of securities by the Company consisting of common stock or other securities that are convertible, exercisable, or exchangeable into shares of the Company's common stock.

In addition to the shares of New Preferred Stock described above, Americas III and UBS Capital LLC are entitled to exchange shares of series B preferred stock of Tutopia for up to 527,775 and 27,778 shares of Series D Preferred Stock, respectively.
