Part IV, Item 3


The registrant expects to report significantly increased expenses and net loss
for the 3 and 9 month periods ended June 30, 2008.

The registrant expects to report operating expenses of approximately $923,831
for the three months ended June 30, 2008, an increase of $471,351 or
approximately 104%, as compared to $452,480 for the three months ended June 30,
2007 and of approximately $7,626,805 for the nine months ended June 30, 2008, an
increase of $6,670,414 or approximately 697%, as compared to $956,391 for the
nine months ended June 30, 2007. General and administrative expenses are
expected to be approximately $634,702 for the three months ended June 30, 2008,
an increase of $190,158 or approximately 43%, as compared to $444,544 for the
three months ended June 30, 2007 and approximately $6,755,429 for the nine
months ended June 30, 2008, an increase of $5,822,761 or approximately 624%, as
compared to $932,668 for the nine months ended June 30, 2007. The increase in
general and administrative expenses is primarily due to the issuance of warrants
and options.

Due to a decrease in warrant liability associated with the decrease in the fair
value of option and warrant liability for the three months ended June 30, 2008,
the registrant expects to report other income and (expense) of $(1,858,881) for
the three months ended June 30, 2008, an increase of $1,784,630 or approximately
2,404%, as compared to $(74,251) for the three months ended June 30, 2007. Due
to an increase in warrant liability and beneficial conversion feature liability,
the registrant expects to report other income and (expense) of approximately
$2,818,497 for the nine months ended June 30, 2008, an increase of $2,962,726 or
approximately 2,054%, as compared to $(144,229) for the nine months ended June
30, 2007. Interest expense is expected to increase to $313,696 during the three
months ended June 30, 2008, an increase of $239,389 or approximately 322%, as
compared to $74,307 for the three months ended June 30, 2007 and to $977,912
during the nine months ended June 30, 2008, an increase of $833,017 or
approximately 575%, as compared to $144,895 for the nine months ended June 30,
2007. The increase is primarily due to the amortization of the beneficial
conversion features discount.


Net loss is expected to be approximately $2,782,712 for the three months ended
June 30, 2008, an increase of $2,255,981 or approximately 428%, as compared to
$526,731 for the three months ended June 30, 2007, and approximately $4,809,208
for the nine months ended June 30, 2008, an increase of $3,707,688 or
approximately 337%, as compared to $1,101,520 for the nine months ended June 30,
