    Financial Results

    For the three months ended September 30, 2007 ("Q3 2007"), the Company
reported a net loss of $1,709,450 or $0.03 per share, compared to $1,351,490
or $0.04 per share for the three months ended September 30, 2006 ("Q3 2006")
and a net loss of $1,817,019 or $0.03 per share for the preceding quarter
ended June 30, 2007 ("Q2 2007"). The net loss for the nine months ended
September 30, 2007 ("Q3 YTD 2007") was $5,133,571 or $0.09 per share compared
to $3,684,687 or $0.10 per share for the nine months ended September 30, 2006
("Q3 YTD 2006"). The $357,960 (26%) and $1,448,884 (39%) increase in net loss
for Q3 2007 and Q3 YTD 2007, respectively, is primarily attributable to
increased research and development costs from expanded drug development and
clinical activities.
    Research and development costs of $1,045,269 were incurred during Q3 2007
compared to $851,924 for the Q3 2006 comparative period and $1,098,890 during
the preceding quarter, Q2 2007. Research and development costs for the Q3 YTD
2007 period totaled $3,185,453 representing a $1,136,927 (55%) increase from
$2,048,526 incurred during the Q3 YTD 2006 comparative period. Similar to Q3
2007, the Q3 YTD 2007 comparative cost increase reflects the expanded scope of
Protox's drug development and clinical trial activities. Q3 YTD 2007 R&D costs
reflect three full quarters of PRX302 Phase 1 prostate cancer clinical trial
costs versus one and a half quarters for Q3 YTD 2006 as the study was
initiated in mid Q2 2006. In addition, incremental costs have been incurred
during Q3 YTD 2007 leading up to the initiation near the end of Q1 2007 of the
Company's PRX302 Phase 1 BPH clinical and for PRX321 CMC activities in advance
of an anticipated H1 2008 PRX321 Phase 2b study for primary brain cancer.
Direct costs for the prostate cancer and BPH Phase 1 clinical studies and
PRX321 Phase 2b preparatory activities totaled approximately $1,876,000 during
Q3 YTD 2007 compared to approximately $1,199,000 for Q3 YTD 2006, contributing
$677,000 (60%) to the overall increase in R&D costs.
    General and administration costs of $427,477 were incurred during Q3 2007
representing a 4% increase compared to $409,656 incurred for the Q3 2006
comparative period. On a Q3 YTD basis, total general and administration costs
of $1,384,939 for the current fiscal year closely approximated the costs of
$1,386,559 incurred during the Q3 YTD 2006 comparative period.
    During Q3 2007 and Q3 YTD 2007, the Company earned interest income of
$63,692 and $252,725, respectively, compared to $32,991 and $102,525 for the
corresponding 2006 comparative periods. The increase in interest income is the
result of higher interest rates earned on higher average amounts held in
interest bearing accounts or investments during the periods.
    During Q3 2007 and Q3 YTD 2007, the Company recorded cumulative foreign
exchange losses of $125,540 and $316,394, respectively, compared to $8,363 and
$41,921 for the corresponding 2006 comparative periods. During Q3 2007, the
U.S. dollar declined approximately 7% against the Canadian dollar contributing
toward the overall year-to-date decline of approximately 15% as of
September 30, 2007.
    As at September 30, 2007, the Company had cash and cash equivalents of
$6.4 million compared to $7.9 and $10.0 million as at June 30, 2007 and
December 31, 2006, respectively. The Company had working capital of
$5.9 million at September 30, 2007, compared to $6.5 million at the end of the
preceding quarter and $8.9 million at December 31, 2006. Excluding warrant and
option exercise proceeds of $0.9 million received, the Company consumed cash
of $2.4 million during Q3 2007 to finance continuing operations compared to
$1.5 million for Q3 2006. Following the exercise of approximately $7.6 million
of a potential $7.7 million worth of warrants issued as a result of the two
tranches of a unit private placement financing closed on November 4 and 17,
2005, the Company's current cash position is approximately $12.0 million.
    As at November 23, 2007, the Company had approximately 68.5 million
common shares issued and outstanding. In addition, the Company had 4.9 million
options to purchase common shares of the Company outstanding, of which
approximately 2.5 million were exercisable into an equivalent number of common
shares of the Company at exercise prices ranging from $0.10 to $1.00 and an
average exercise price of $0.71.
