         holders of any class or classes of the capital stock of the Company
         with respect to any proposed Senior Equity Financing, (A) it shall vote
         (or cause to be voted) all of its Shares in favor of and/or consent in

         convertible, exercisable or exchangeable for or into common stock at an
         effective price of less than the Benchmark Price, and any options,

              acquiror and (1) such equity is not traded on an Authorized Stock
              Exchange (as defined below) or, (2) if such equity is traded on an
              Authorized Stock Exchange, (A) the consideration shares have not
              been registered pursuant to an effective registration statement
              (if registration is required for such consideration shares to
              trade on the applicable Authorized Stock Exchange) or (B) the
              average daily trading volume for such acquiror's listed equity
              during the 180-trading day period immediately preceding the
              closing of such Non-Qualifying Sale is less than $1,000,000 per
              day (as determined by multiplying the daily number of shares
              traded by the average of the high and low bid prices each day), in
              each case unless the consideration also includes cash in an amount
              equal to or greater than the Benchmark Price; or

                   (y) the consideration takes the form of cash and the purchase
              price is less than the Benchmark Price.
