AETERNA ZENTARIS TO FILE RESTATED INTERIM 2006 THIRD QUARTER FINANCIALS

NET LOSS FOR THE THIRD QUARTER AND THE NINE-MONTH PERIOD ENDED SEPTEMBER 30,
2006 DECREASES BY $4.9 MILLION

ALL AMOUNTS ARE IN U.S. DOLLARS

QUEBEC CITY, CANADA, FEBRUARY 12, 2007 - AEterna Zentaris Inc. (TSX: AEZ;
NASDAQ: AEZS) today announced that the Company, after discussions with its
external auditors relating to the Company's and the auditors' interpretation of
Section 3465 of the Canadian Institute of Chartered Accountants ("CICA")
Handbook, has determined to restate its interim unaudited consolidated financial
statements for the third quarter and nine-month period ended September 30, 2006.
This non-cash restatement will reduce the Company's future income tax expense
and its net loss by $4.9 million for the third quarter and nine-month period
ended September 30, 2006. AEterna Zentaris' restated net loss will be $1.6
million for the three-month period and $5.7 million for the nine-month period
ended September 30, 2006, compared to the previously reported net loss of $6.5
million and $10.6 million for such periods, respectively. The Company's net loss
per share on a basic and fully-diluted basis will be $0.03 for the three-month
period and $0.11 for the nine-month period ended September 30, 2006, compared to
the previously reported $0.12 and $0.21 for such periods, respectively. The
impact on the consolidated balance sheet will be a decrease in the future income
tax liabilities of $5 million, a decrease in the deficit of $4.9 million and an
increase in the cumulative translation adjustment of $0.1 million.

Section 3465 of the CICA Handbook provides guidance related to the valuation of
future income tax assets in connection with income tax losses. The valuation of
the $4.9 million allowance previously recorded in the Company's consolidated
statement of operations as future income tax expense in the third quarter ended
September 30, 2006 has been reversed. Furthermore, in conjunction with the
aforementioned restatement, future income tax assets and liabilities arising
from within the same jurisdiction have also been offset as required by Section
3465.

The Company anticipates filing the restated third quarter 2006 interim financial
statements and the corresponding Management's Discussion and Analysis (MD&A)
later today. These documents will be available on www.sedar.com and on the
Company's website at www.aeternazentaris.com. A summary of certain restated
financial information is attached to this press release.
