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."

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.

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.
