1.          AEterna's Interim Report 2003 - Third Quarter (Q3)
---------  ---------------------------------------------------------------------
















November 5, 2003

To our stockholders,

At the financial level, this quarter was marked mainly by substantial revenues
from Cetrotide(R), a marketed novel treatment for in vitro fertilization, and by
the strong growth in sales and net earnings from our subsidiary Atrium, which
acquired Chimiray/Interchemical in August of this year.

At the clinical development level, our kidney cancer Phase III trial with
Neovastat did not meet its main clinical endpoint. However, we are pursuing our
non-small cell lung cancer Phase III trial, whereby Neovastat is administered on
a first-line basis in combination with standard treatment.

In addition, many other products in oncology, endocrinology and infectious
diseases ensure a constant flow of high potential projects. Two already marketed
products are gaining new market share; Cetrotide(R), a novel treatment for IN
VITRO fertilization, and Impavido(R), sold in India as the first oral treatment
for the visceral form of leishmaniasis, better known as black fever, which can
prove life-threatening. Last July, we released positive Phase III trial results
still with Impavido(R), this time for the cutaneous form of leishmaniasis, a
severe parasitic skin disease prevalent in South America. As a matter of fact,
we are currently preparing to file for its eventual approval on that continent.
Finally, we are completing Phase II trials with Cetrorelix for uterus myoma,
endometriosis and benign prostatic hyperplasia, diseases that affect millions of
people worldwide.

Considering the scope of our pipeline, the strength of our international
partnership network, the profitability of our subsidiary Atrium and our $75
million cash position, I am confident that the Company is well positioned to
pursue its long-term growth.

THIRD QUARTER 2003 HIGHLIGHTS

o    PHASE III TRIAL RESULTS FOR NEOVASTAT IN KIDNEY CANCER - In September, we
     reported Phase III trial results for Neovastat in renal cell carcinoma, a
     form of kidney cancer. The study involved 305 patients and did not reach
     its primary endpoint, which was to increase the median survival time of
     treated patients by 50%.

o    POSITIVE PHASE III RESULTS FOR IMPAVIDO(R) IN CUTANEOUS LEISHMANIASIS
     (PARASITIC SKIN DISEASE) - In July, we reported positive results of a Phase
     III trial evaluating Impavido(R) (Miltefosine) for the treatment of
     cutaneous leishmaniasis, a severe skin disease. The data showed that
     patients taking Impavido(R) had a 220% better cure rate than those in the
     placebo group. These favorable data enable the Company to apply for
     marketing authorization in South American countries where the cutaneous
     form of the disease is predominant. Impavido(R) is currently sold in India
     and is the only oral cure for the life-threatening visceral form of
     leishmaniasis.





o    CLOSING OF A $35.6 MILLION BOUGHT DEAL - In July, we closed a $35.6 million
     bought deal, issuing 4.5 million subordinate voting shares at $7.90 per
     share. The net proceeds of $33.8 million of this financing will be used to
     further develop the product pipeline, pursue the Company's growth strategy
     and general corporate purposes.

o    ACQUISITION OF CHIMIRAY/INTERCHEMICAL BY ATRIUM BIOTECHNOLOGIES - In
     August, our subsidiary, Atrium, acquired 100% of all issued and outstanding
     shares of Chimiray/Interchemical for E11.5 million ($18.4 million), payable
     by the issuance of a long-term debt of E5 million ($8 million) and the
     residual of E6.5 million ($10.4 million) in cash. Based in Paris,
     Chimiray/Interchemical is focused mainly in the distribution of fine
     chemicals and active ingredients. Net sales for the last twelve-month
     period were approximately E35 million ($52 million). The company generated
     net earnings and was cash flow positive.

On behalf of my colleagues and our Board of Directors, I thank you for your
continued interest and support.


Sincerely,


/s/ GILLES GAGNON

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION

The following analysis explains the variations in the Company's results of
operations, financial condition and cash flow. It provides an update to the
discussion and analysis contained in our Annual Report of 2002. This discussion
and analysis should be read in conjunction with the information contained in
AEterna Laboratories Inc.'s interim consolidated financial statements and
related notes for the nine-month periods ended September 30, 2003 and 2002. All
figures are in Canadian dollars.

CRITICAL ACCOUNTING POLICIES

Our critical accounting policies are disclosed in the "Management's Discussion
and Analysis of Financial Condition and Results of Operations" section and the
annual consolidated financial statements contained in our 2002 Annual Report.
Our financial statements are prepared in accordance with the Canadian Generally
Accepted Accounting Principles (GAAP) and access to a summary of differences
between Canadian and US GAAP is possible by consulting note 20 of our annual
2002 financial statements.

RESULTS OF OPERATIONS

REVENUES

Revenues for the third quarter ended September 30, 2003 were $37.8 million
compared to $24.4 million for the same period last year. For the nine-month
period ended September 30, 2003, the consolidated revenues were $117.5 million
compared to $73.2 million in 2002. This increase for the quarter as well as for
the first nine months of the year comes from the Biopharmaceutical segment with
revenues totalling $34.7 million, as of September 30, 2003. The balance of $9.6
million comes from the Cosmetics & Nutrition (C&N) and the Distribution
segments, representing an increase of 13% compared to the same period of 2002
for these segments.

The acquisition, in December 2002, of Frankfurt-based Zentaris provided most of
the revenues in the Biopharmaceutical segment for this quarter as well as for
the nine-month period. Revenues in this segment were generated by the marketing
of Cetrotide(R) and Impavido(R), milestone payments, research and development
contract fees and the amortization of up-front payments.

The increase of revenues in the C&N and the Distribution segments is generated
by a continued growth of the C&N segment and by the acquisition, last August, of
Chimiray/Interchemical in the Distribution segment.

OPERATING EXPENSES

The cost of sales during this quarter amounted to $23.5 million compared to
$18.9 million for the same quarter in 2002. For the nine-month period ended
September 30, 2003, the cost of sales has raised from $56.3 million to $67.2
million. The gross margin totalled $8.2 million (25.7%) in the third quarter of
2003 in comparison with $5.5 million (22.7%) in 2002, representing an increase
of 47%. These costs are in direct proportion to corresponding revenues and their





percentage decreased by 3%. For the nine-month period, the gross margin has
raised from $16.8 million in 2002 to $22.2 million this year, for an increase
of 31%.

Selling, general and administrative expenses amounted to $7.5 million during
this quarter compared to $3.9 million in 2002. Regarding the nine-month period,
selling, general and administrative expenses were $19.4 million compared to
$12.1 million in 2002. This increase is attributed to the Biopharmaceutical
segment for an amount of $5.1 million, as a result of the acquisition of
Zentaris made last December. In addition, the C&N and Distribution segments
increased their selling expenses by $2 million as a result of the acquisition of
Chimiray/Interchemical as well as the increase in their sales force.

Research and Development (R&D) investments, net of R&D tax credits and grants,
amounted to $9.8 million during this quarter in comparison with $6.5 million
last year. As of September 30, 2003, net R&D investments reached $31.7 million
in comparison with $17.1 million in 2002. This increase is attributed to the
acquisition of Zentaris, whereby the net investment in R&D amounted to $4.3
million for this quarter and $15.6 million for the nine-month period ended
September 30, 2003. Therefore, the level of investment for Neovastat, our lead
antiangiogenic compound in oncology, was approximately the same as last year
since the Phase III program was actively ongoing for renal cell carcinoma and
non-small cell lung cancer during this period.

Depreciation and amortization (D&A) for this third quarter amounted to $2.3
million compared to $0.6 million in 2002. For the nine-month period ended
September 30, 2003, D&A amounted to $6.9 million compared to $1.7 million for
the same period last year. This significant increase is mainly related to the
amortization of Zentaris technologies acquired in December 2002 with an amount
of $3.8 million for the nine-month period ended September 30, 2003. The purchase
price allocation has been completed during the second quarter and an amount of
$12 million was allocated to goodwill from identified intangible assets. We
expect that the amortization expense for 2003 will increase significantly over
that of the 2002 fiscal year due to the intangible additions incurred at the end
of 2002.

The operating loss (before financial items, income tax expenses and
non-controlling expenses) amounted to $5.3 million during this quarter in
comparison with $5.5 million in 2002. For the nine-month period of 2003, the
operating loss was $7.6 million compared to $14 million in 2002 resulting in a
decrease of $6.4 million. This significant reduction is related to the increase
of gross margin within our C&N and Distribution segments, as well as to new
revenues generated by our Biopharmaceutical segment.

Interest income has decreased from $0.7 million to $0.5 million for this quarter
compared to the same quarter of 2002. The decrease for this quarter, as well as
for the nine-month period ended September 30, 2003, is primarily due to the cash
used for the Zentaris transaction, as well as to the reduction in market yield
available on short-term investments. The interest and financial expenses, for
this quarter as well as for the nine-month period, mainly include the financing
cost on the convertible term loans, the balance of purchase price settled in
March 2003 and the promissory note of $43 million reimbursed last January as
interim financing related to Zentaris' acquisition.






A net foreign exchange gain of $0.1 million was recorded during the quarter
ended September 30, 2003 as well as for last year. This gain is attributable to
the stability of the Canadian dollar over the US dollar during the last quarter.
For the nine-month period ended September 30, 2003, the net foreign exchange
loss amounted to $1.3 million compared to a loss of $0.2 million in 2002. This
loss is attributable to the effect of the strengthening Canadian dollar on our
US investment portfolio and working capital denominated in US dollars. We are
maintaining US dollar cash and cash equivalent and short-term investments to
meet our future expenditures in US dollars.

Income tax expense was $2.1 million during this quarter compared to $0.9 million
in 2002. From the beginning of the year, income tax expense amounted to $5.3
million in comparison to $3.1 million in 2002. Income tax expense relates to
profitable companies within our group.

The net loss for this quarter amounted to $9.2 million or $0.20 per share in
2003 compared to a net loss of $6.2 million or $0.15 per share for the same
quarter in 2002. For the nine-month period ended September 30, 2003, the net
loss was $18.6 million or $0.43 per share compared to $17.8 million or $0.46 per
share last year.

LIQUIDITY AND CAPITAL RESOURCES

The financial position of the Company remains strong with $75.4 million in cash
and short-term investments as at September 30, 2003. During this quarter, we
closed a bought deal financing on July 24, 2003 with the issuance of 4.5 million
subordinate voting shares at $7.90 per share. This financing will be used to
further develop our product pipeline, to pursue our growth strategy based on
strategic alliances and acquisition of new technologies and for general
corporate purposes.

During this quarter, an amount of $1.1 million was used for operating
activities. The cash flow used in investing activities amounted to $14.7 million
of which an amount of $14.4 million was used for the acquisition of
Chimiray/Interchemical and an additional portion of Unipex Finance S.A.
Furthermore, an amount of $0.3 million was used for the acquisition of
long-lived assets. The cash flow from financing activities amounted to $42
million in this quarter and is explained by the bought deal mentioned above, for
net proceeds of $34.1 million, and by the issuance of a long-term debt of $7.9
million related to the acquisition of Chimiray/Interchemical.

For the nine-month period ended September 30, 2003, an amount of $8.5 million
was used in operational activities. The cash flow used in investing activities
amounted to $18.3 million of which $17 million were used for the acquisition of
Chimiray/Interchemical and an additional portion of Unipex Finance S.A.
Furthermore, an amount of $1.3 million was used for the acquisition of
long-lived assets. The cash flow from financing activities amounted to $20.9
million as a result of inflows generated by the bought deal, the convertible
loan and the issuance of a long-term debt totalling $66.3 million, as well as
outflows for the reimbursement of the promissory note and the balance of
purchase price for an amount of $45.4 million.

research and development (R&D) were valued using a discounted cash flow approach
resulting in an allocated fair value of $66.9 M. The in-process R&D would
require further development. The goodwill related to this transaction was valued
at $12 M and, according to GAAP, it will be not amortized but tested annually
for impairment in relation to the fair value this reporting unit to which
goodwill applies.
