Protox has not earned any revenue in any of its previous fiscal years, other than income from interest earned on the Company's cash balances. During 2008 Q3 and the nine months ended September 30, 2008 ("2008 YTD") the Company earned interest income of $0.09 million and $0.23 million, respectively, compared to $0.06 million and $0.25 million for the corresponding 2007 comparative periods. The variance in interest income is a result of the investment products, interest rate and/or average cash balanced invested. Interest income is anticipated to continue to vary given the current and expected near term market environment.


The Company reported a net loss for 2008 Q3 of $2.5 million or $0.03 per share compared to $1.7 million or $0.03 per share for the three months ended September 30, 2007 comparative period ("2007 Q3"). The net loss for 2008 YTD totaled $6.4 million or $0.09 per share compared to $5.1 million or $0.09 per share for the nine months ended September 30, 2007 ("2007 YTD").


Research and development ("R&D") costs of nearly $2.0 million were incurred during 2008 Q3, as compared to $1.0 million incurred for the 2007 Q3 comparative period. For the 2008 YTD period, R&D costs totaled $4.6 million representing a $1.4 million (45%) increase from $3.2 million incurred during the 2007 YTD comparative period. The increase for both the 2008 Q3 and 2008

YTD periods reflects the continuing effect of the expanded scope and advancement of Protox's drug development and clinical trial activities.


Since the beginning of the year, incremental costs have been incurred for clinical and regulatory preparation activities. During the first three quarters of 2007, the scope and related cost of PRX321 CMC/drug supply manufacturing activities were significantly less while GBM Phase 2b clinical trial planning activities were nominal on a comparative basis. In addition, the early 2008 initiation of the PRX302 Phase 2a BPH study and enrolment completion during 2008 Q3 resulted in higher costs compared to 2007 YTD during which the predecessor Phase 1 study was initiated in mid 2007 Q2 and only partially enrolled by the end of 2007 Q3. A milestone payment relating to the PRX302 prostate cancer program also contributed to increased R&D costs earlier in 2008. Discovery research costs for 2008 Q3 were $0.2 million compared to $0.1 million for 2007 Q3, and increased roughly 50% from $0.4 million for 2007 YTD to $0.6 million for the 2008 YTD period. The increases in Discovery research costs reflect incremental spending associated with expanded CRADA and collaborative research activities for the Company's technology platforms.


General and administrative ("G&A") costs for 2008 Q3 declined 13% to $0.48 million from $0.55 million last quarter, however, increased 12% from $0.43 million incurred during the 2007 Q3 comparative period. YTD G&A costs have also increased at a similar rate to $1.57 million from $1.38 million for the 2007 YTD comparative period, although half of the increase is attributable to a one-time listing fee of $0.1 million incurred during 2008 Q1 when the Company graduated from the TSX Venture Exchange to the Toronto Stock Exchange. G&A costs will generally vary from period to period depending on the specific business development, market research and shareholder relations initiatives undertaken and related travel required at such time to support the Company's corporate objectives. The 2008 Q3 and 2008 YTD G&A costs increase is commensurate with the growth of the Company and its operations and also reflects an increase in business development personnel and activities.


During 2008 Q3 and 2008 YTD, the Company recorded nominal foreign exchange losses as the relative value of the U.S. and Canadian dollar changed marginally. However, during the 2007 Q3 and 2007 YTD comparative periods, $0.13 and $0.32 million of losses were recorded respectively with the majority representing unrealized losses on the Company's then more significant U.S. dollar reserves due to an approximate 15% relative decline in the value of the U.S. dollar during the first three quarters of 2007. The foreign exchange loss or gain recorded for a particular period and difference between comparative periods is a function of prevailing foreign exchange rates in effect at such time compared to the comparative period(s) as well as the amount of net financial assets or liabilities held or transacted during the subject periods.


At September 30, 2008, the Company had cash and cash equivalents of $9.8 million, a net decrease of $1.7 million from December 31, 2007. The Company had working capital of $8.5 million at September 30, 2008, a decrease of $1.2 million from the December 31, 2007.


As at November 11, 2008, the Company has 75,894,044 common shares issued and outstanding. In addition, the Company has 5,032,500 options outstanding to purchase common shares of the Company. Of the options currently outstanding, approximately 3.2 million are exercisable into an equivalent number of common shares of the Company at exercise prices ranging from $0.50 to $1.00 and with an average exercise price of $0.81. The Company also has warrants outstanding entitling warrant holders to purchase common shares as follows: i) 10,938,882 warrants
with an exercise price of $0.65 per common share and an expiry date of December 22, 2008 and ii) 584,413 warrants with an exercise price of $0.71 and expiry date of May 23, 2010.
