[AETERNA ZENTARIS LOGO] - September - Appointment of Juergen Engel, Ph.D., as Company President and CEO, succeeding Juergen Ernst who, at the same time, was appointed as Executive Chairman of the Company. - October and November - Completion of patient recruitment for the second efficacy trial of the Phase 3 program with cetrorelix in BPH. - Initiation of the second stage of patient recruitment for AEZS-108 Phase 2 trial in advanced ovarian and endometrial cancers. - December - Sale of AEterna Zentaris rights to royalties on future sales of Cetrotide(R), covered by the Company's license agreement with Merck Serono, to Cowen Healthcare Royalty Partners L.P. ("Cowen") for gross consideration of $52.5 million. - Completion of patient recruitment for the safety trial of the Phase 3 program in BPH with cetrorelix. - Appointment of Matthias Seeber, MBA, as Company Senior Vice President, Administration and Legal Affairs. - Subsequent to year end - The Company entered into a development, commercialization and license agreement with sanofi-aventis for the development, registration and marketing of cetrorelix in BPH for the United States market. The agreement includes an initial upfront payment of $30 million and up to $135 million in additional payments upon achieving certain pre-established regulatory and commercial milestones, as well as escalating double-digit royalties on future net sales of cetrorelix for BPH in the United States. Juergen Engel, Ph. D., AEterna Zentaris' President and Chief Executive Officer commented, "I am proud of our achievements of the past 12 months. At the financial level, we generated nearly $100 million in 2008 and in the first few months of 2009, through multiple non-dilutive transactions and a major pharmaceutical partnership with sanofi-aventis for our lead compound, cetrorelix. At the drug development level, we completed the recruitment of over 1,600 patients for our Phase 3 program in BPH with cetrorelix, according to schedule. We now look forward to disclosing results of this program throughout the second half of 2009. We also made significant progress with our lead oncology compound, AEZS-108, in endometrial and ovarian cancer with results expected by the end of this year. Moving forward, we will continue to concentrate our efforts on bringing cetrorelix closer to market in collaboration with our partner, sanofi-aventis. We believe that this compound could prove to be a novel treatment for the benefit of millions of men with BPH and also build value for our shareholders." Dennis Turpin, Senior Vice President and Chief Financial Officer of AEterna Zentaris added, "The non-dilutive transactions and the recent partnership with sanofi-aventis have provided the Company with an overall stronger financial position and with the necessary funds to pursue our growth strategy." -2- [AETERNA ZENTARIS LOGO] CONSOLIDATED RESULTS FOR THE FOURTH QUARTER ENDED DECEMBER 31, 2008 CONSOLIDATED REVENUES were $7.2 million for the quarter ended December 31, 2008, compared to $10.2 million for the same quarter in 2007. The decrease in revenues is primarily due to lower quarter-over-quarter royalties related to our license agreement with Merck Serono. Subsequent to the sale of the Company's rights to royalties on future sales of Cetrotide(R), covered by the Company's license agreement with Merck Serono, to Cowen, which was effective, for royalty determination purposes, on October 1, 2008, our periodic amortization of the gross proceeds received from Cowen, while still recognized as royalty revenues, has been lower than the royalty revenues recognized in the past, as receivable directly from Merck Serono. Additionally, quarter-over-quarter sales and royalties decreased due to the absence of sales of Impavido(R) in the fourth quarter of 2008, while license revenues witnessed a decrease due to the non-recurrence in 2008 of milestone payments received from one of our partners, related to the perifosine Phase 2 trials. CONSOLIDATED SELLING, GENERAL AND ADMINISTRATIVE ("SG&A") EXPENSES were $3.0 million for the quarter ended December 31, 2008, compared to $5.1 million for the same quarter in 2007. The decrease in SG&A expenses is mainly related to the continued results of cost-saving measures that were implemented beginning in the second quarter of 2008. CONSOLIDATED RESEARCH AND DEVELOPMENT ("R&D") EXPENSES were $12.3 million for the quarter ended December 31, 2008, compared to $13.6 million for the same quarter in 2007. The decrease in R&D expenses primarily relates to the comparative reduction in expenses incurred in connection with our Phase 3 program with cetrorelix in BPH, which by the fourth quarter of 2008 was fully enrolled and less subject to larger front-end expenditures that were necessary in the earlier, fourth quarter 2007 stage of the program. CONSOLIDATED NET LOSS was $14.5 million, or $0.27 per basic and diluted share for the quarter ended December 31, 2008, compared to $13.6 million, or $0.26 per basic and diluted share, for the same quarter in 2007. The increase in consolidated net loss is largely attributable to a combination of lower sales and royalties, lower license fee revenues, lower manufacturing margins on Cetrotide(R) due in part to a $0.7 million write-down to net realizable value of certain components of inventory, as well as to higher amortization expense, partly offset by lower quarter-over-quarter SG&A expenses, higher net foreign exchange gains and lower income tax expense. CONSOLIDATED CASH, CASH EQUIVALENTS AND SHORT-TERM INVESTMENTS were $49.7 million as at December 31, 2008. CONSOLIDATED RESULTS FOR THE FULL YEAR ENDED DECEMBER 31, 2008 CONSOLIDATED REVENUES were $38.5 million for the year ended December 31, 2008, compared to $42.1 million for the year ended December 31, 2007. The decrease in consolidated revenues in 2008 compared to 2007 is primarily related to lower sales of Impavido(R), a decrease in consolidated license fee revenues mainly attributable to non-recurring milestone payments and the termination of a partner licensing agreement in 2007, partly offset by an increase in sales of Cetrotide(R). CONSOLIDATED SG&A EXPENSES decreased to $17.3 million for the year ended December 31, 2008, compared to $20.4 million for the year ended December 31, 2007. The decrease in SG&A expenses is primarily related to the organizational changes and cost-saving measures that were implemented beginning in the second quarter of 2008. -3- [AETERNA ZENTARIS LOGO] CONSOLIDATED R&D COSTS were $57.4 million for the year ended December 31, 2008, compared to $39.2 million for the year ended December 31, 2007. The increase in consolidated R&D costs for the year 2008 compared to 2007 is mainly attributable to the advancement of our Phase 3 program with our lead compound, cetrorelix, in BPH. CONSOLIDATED NET LOSS was $59.8 million, or $1.12 per basic and diluted share, for the year ended December 31, 2008, compared to $32.3 million, or $0.61 per basic and diluted share, for the year ended December 31, 2007. The increase in consolidated net loss is attributable to a combination of lower license fee revenues, lower manufacturing margins, higher R&D costs, higher depreciation and amortization and higher income tax expense, partly offset by lower SG&A expenses and higher net foreign exchange gains.
