       Contractual Arrangements Between Shareholders with Respect
       to the S&P/TSX Composite Index

                                                                  PRESS RELEASE
                                                          FOR IMMEDIATE RELEASE

                    AEterna Details Contractual Arrangements
        Between Shareholders with Respect to the S&P/TSX Composite Index

QUEBEC CITY, QUEBEC, SEPTEMBER 18, 2002 - AEterna Laboratories Inc. (TSX: AEL;
Nasdaq: AELA) wishes to confirm that, with respect to shareholders' contractual
arrangements entered into in connection with the $55 million private placement
transaction completed on April 9, 2002, there is no control block, voting group,
single shareholder or combination of related shareholders holding more than 20%
of AEterna's outstanding subordinate voting shares. Therefore, in AEterna's
view, 100% of AEterna's outstanding subordinate voting shares should be
considered as its float for the purposes of the S&P/TSX Composite Index.

As part of the private placement transaction, Dr. Eric Dupont, Chairman and CEO
of AEterna, in his capacity as a shareholder of AEterna, entered into an
agreement with SGF Sante under which he agreed not to take certain corporate
actions without the prior written consent of SGF Sante, among them modifications
to the articles and by-laws of AEterna, the relocation of AEterna's principal
place of business outside of Quebec, a material change to the nature of
AEterna's business, a sale of all or substantially all of the assets of AEterna,
and any corporate reorganizations involving AEterna. Under the terms of the SGF
Sante agreement, Dr. Dupont also agreed to vote all equity shares held by him in
favour of an SGF Sante nominee to the board of directors of AEterna, which is
currently composed of 8 members, and to select jointly with SGF Sante an
additional candidate for AEterna`s board at the annual meeting to be held in
2003. At no time did SGF Sante or Dr. Dupont agree, directly or indirectly, to
vote their shares in AEterna together, to consult with one another prior to
exercising such voting rights or to give instructions to one another as to how
their respective shares should be voted.

Concurrently with the entering into of the SGF Sante agreement, Dr. Dupont
entered into a separate, stand-alone agreement with Solidarity Fund QFL,
pursuant to which he agreed not to relocate AEterna's principal place of
business outside of Quebec without the prior consent of Solidarity Fund. Under
this agreement, the consent of Solidarity Fund is not required with respect to
any other corporate matters involving AEterna. In addition, this agreement, does
not afford Solidarity Fund the right to appoint a nominee to the board of
directors of

AEterna, nor does it provide Solidarity Fund with any voting rights with respect
to AEterna.

Solidarity Fund is not a party to the SGF Sante agreement, and SGF Sante is not
a party to the Solidarity Fund agreement. There are no agreements or
arrangements between SGF Sante and Solidarity Fund concerning the manner in
which either of them will exercise the rights conferred to them under their
respective agreements. AEterna is not a party to either agreement.

AEterna therefore wishes to confirm that, with respect to the contractual
arrangements entered into in connection with the private placement transaction,
there are no voting arrangements among SGF Sante, Solidarity Fund and Dr. Dupont
as a group.

As at August 30, 2002, SGF Sante beneficially owned 5,333,334 subordinate voting
shares of AEterna (representing 14.98% of the issued and outstanding subordinate
voting shares of AEterna), Solidarity Fund beneficially owned 4,996,525
subordinate voting shares (representing 14.04% of the outstanding subordinate
voting shares) and Dr. Dupont beneficially owned 151,200 subordinate voting
shares (representing 0.42% of the outstanding subordinate voting shares).
Moreover, Dr. Dupont is the beneficial owner of 4,850,623 multiple voting shares
of AEterna.
