(B) The Company's obligation to include Restricted Securities in a Company's Registration Statement pursuant to Section 7(a) shall be subject to the following limitations: (1) The Company may elect, at its sole option and for any reason, not to register holder's Restricted Shares, provided however, that this right is limited to one (1) time and relative to one (1) particular Company Registration Statement.

For purposes of the foregoing proviso, the aggregate number of shares of Common Stock beneficially owned by the holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of this Note with respect to which the determination of such proviso is being made, but shall exclude the number of shares of Common Stock which would be issuable upon (i) conversion of the remaining, unconverted Note beneficially owned by such holder and its affiliates, and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company (including without limitation any warrants) which are beneficially owned by the holder and its affiliates and which are subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended.
