            AETERNA ENTERS INTO A $25 MILLION CONVERTIBLE TERM LOAN
                  AND COMPLETES THE INTEGRATION OF ZENTARIS AG

                  CERTAIN WARRANTS ISSUED IN APRIL 2002 EXPIRE

ALL AMOUNTS ARE IN CANADIAN DOLLARS

QUEBEC CITY (CANADA), APRIL 1, 2003 -- Aeterna Laboratories Inc. (TSX: AEL,
NASDAQ: AELA) today announced that, on March 31, 2003, it entered into a term
loan facility with two strategic investors: SGF Sante Inc. and Solidarity Fund
QFL. The term loan is in a principal amount of $25 million ($12.5 million per
investor), matures on March 31, 2006 and bears interest at an annual rate of
12%. Interest is payable once a year on the anniversary date of the term loan,
subject to Aeterna's right to defer payment of interest on the term loan until
March 31, 2006. SGF Sante and Solidarity Fund QFL have the option to convert all
or any part of the loan, plus accrued and unpaid interest thereon, into
subordinate voting shares of Aeterna, at a price of $5.05 per share. This
represents a 25% premium over the 10-day weighted average trading price ending
on March 28, 2003, the last trading day prior to the completion of this
transaction. The term loan is secured by certain of Aeterna's assets. The
proceeds of this loan will be used for current operating activities of the
Company.

Aeterna also announced today the merger of its subsidiaries Aeterna GmbH and
Zentaris AG, thus completing the integration of Zentaris AG, which was acquired
in December 2002, providing Aeterna with eleven additional products ranging from
preclinical stage up to marketing, as well as several pharmaceutical partners.
The company resulting from this merger will be called Zentaris GmbH. As
previously announced, this merger has enabled Aeterna to settle the balance of
purchase price for Zentaris AG of $40 million to Degussa AG.

"With the combination of today's term loan with SGF Sante and Solidarity Fund
QFL and the settlement of the balance of purchase price for Zentaris, Aeterna's
cash position is in excess of $50 million. Our financial strength and cash
position is bolstered through the profitable activities of Atrium
Biotechnologies and the cash flow generated by Zentaris," commented Dennis
Turpin, CA, Aeterna's Vice President and CFO.

"We are very pleased with the continued support from SGF Sante and Solidarity
Fund QFL. With this financing, as well as the integration of Zentaris and the
magnitude and




quality of our new product portfolio, we are well positioned to pursue our
growth strategy, along with the collaboration of all our partners," stated
Gilles Gagnon, Aeterna's President and CEO.

During the last three months, several important events took place following the
acquisition of Zentaris:

     o    Agreement with Hainan Tianwang International Pharmaceutical for the
          manufacturing and marketing of Lobaplatin(R), throughout the Chinese
          territory. Lobaplatin(R) is an agent derived from platinum used for
          cancer treatment. This agreement provides, among other things, a cash
          receipt of $4.5 million.

     o    Appointment of Zentaris' key employees to Board of Directors and
          management positions of Aeterna Laboratories Inc.

     o    Agreement with Baxter Healthcare granting exclusive worldwide rights
          to product D-63153 for all forms of cancer and for endocrinological
          use. This agreement provides for undisclosed payments, assumption of
          100% of the clinical development costs, and a certain number of
          additional milestone payments.

     o    Exclusive distribution and marketing agreement with German Remedies
          Limited for marketing Impavido(R) (Miltefosine) in India and
          Bangladesh. This marks the beginning of worldwide marketing of
          Miltefosine, which will soon be available in all countries afflicted
          by Leishmaniasis, better known as the Black Fever.

     o    Confirmation of positive financial results of Zentaris for the year
          2002, with more than $30 million in revenue and a positive cash flow.

     o    Agreement with LG Life Sciences Ltd. for marketing Neovastat in the
          Korean territory.

In addition, Aeterna announced today that the 2,000,000 warrants and 1,666,667
warrants issued to SGF Sante and Solidarity Fund QFL, respectively, on April 9,
2002 in connection with a $57 million private placement of subordinate voting
shares expired in accordance with their terms on March 31, 2003 and have been
cancelled. SGF Sante and Solidarity Fund QFL still own 2,000,000 and 1,666,667
warrants, respectively, which may be exercised on or before December 31, 2003 at
an exercise price of $20 per subordinate voting share.
