Based
on 166,017,599 shares outstanding as of September 9, 2005, and
assumes the
issuance of common stock offered in this prospectus. The number
set forth
above does not include approximately 24,540,000 shares of our
common stock
that, as of September 9, 2005, are issuable upon the exercise
of
outstanding options and warrants. These options and warrants
are
exercisable at prices ranging from $0.34 to $5.28 per share,
with an
average exercise price of $1.71 per share. With regard to options
to

standstill
agreements from the holders of these options pursuant to which
they have
agreed not to exercise such options until we have obtained approval
from
our stockholders to increase our authorized shares of common
stock. In
the event that stockholder approval to increase our authorized
shares is
not obtained at our annual stockholder meeting to be held on
October 24,
2005, then we may need to file a post-effective amendment to
the
registration statement of which this prospectus is a part to
de-register
up to 3,100,000 shares. Prior to receiving stockholder approval, we
will not offer to sell more than 8,900,000 shares covered by
