Restriction. Notwithstanding anything to the contrary set forth in
Section 5 of this Certificate of Designation, at no time may a holder of shares
of Series A Preferred Stock convert shares of the Series A Preferred Stock if
the number of shares of Common Stock to be issued pursuant to such conversion
would cause the number of shares of Common Stock owned by such holder and its
affiliates at such time to exceed, when aggregated with all other shares of
Common Stock owned by such holder and its affiliates at such time, the number of
shares of Common Stock which would result in such holder and its affiliates
beneficially owning (as determined in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended, and the rules thereunder) in excess
of 9.9% of the then issued and outstanding shares of Common Stock outstanding at
such time; provided, however, that upon a holder of Series A Preferred Stock
providing the Company with sixty-one (61) days notice (pursuant to Section 5(i)
hereof) (the “Waiver Notice”) that such holder would like to waive Section 7 of
this Certificate of Designation with regard to any or all shares of Common Stock
issuable upon conversion of the Series A Preferred Stock, this Section 7 shall
be of no force or effect with regard to those shares of Series A Preferred Stock
referenced in the Waiver Notice.”
