EXHIBIT 2 REPORT OF INDEPENDENT AUDITORS TO THE SHAREHOLDERS OF AETERNA LABORATORIES INC. We have audited the consolidated balance sheets of AETERNA LABORATORIES INC. as at December 31, 2003 and 2002 and the consolidated statements of operations, deficit, other capital and cash flows for each of the years in the three-year period ended December 31, 2003. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with Canadian generally accepted auditing standards. Those standards require that we plan and perform an audit to obtain reasonable assurance whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. In our opinion, these consolidated financial statements present fairly, in all material respects, the financial position of the Company as at December 31, 2003 and 2002 and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2003 in accordance with Canadian generally accepted accounting principles. /s/ PricewaterhouseCoopers LLP CHARTERED ACCOUNTANTS Quebec, Quebec, Canada February 25, 2004, except as to note 25 which is as of March 3, 2004 COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. REPORTING DIFFERENCES In the United States of America, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when there are changes in accounting principles that have a material effect on the comparability of the Company's financial statements, such as the changes described in note 3 to the consolidated financial statements.
