       On December 8, 2005, the Corporation announced the acquisition by its
       subsidiary, Atrium Biotechnologies Inc. ("Atrium"), of HVL Parent
       Incorporated and subsidiary, a company located in Pittsburgh, PA and

2.3 -- CONSIDERATION

       The price of the acquisition was US$86,922,000. A part of this purchase
       price (US$8,632,000) was paid by the issuance of Atrium's subordinate
       voting shares at a price of CAN$10.95 per share; thus, 917,532 shares of
       the Atrium's capital stock were issued to some of the sellers. These
       shares cannot be sold or transferred as per the following conditions. One
       third of the shares will be allowed to be sold or transferred on the next
       three anniversaries of the closing of the transaction. In addition,
       Atrium reimbursed the existing debt of the HVL group of companies for an
       amount of US$8,904,000 in principal.

       The cash portion of the purchase price as well as the reimbursement by
       Atrium of HVL's existing debt were funded by Atrium using cash on hand
       and financed through a credit facility provided and arranged by National
       Bank of Canada, Royal Bank of Canada and HSBC Bank Canada.

[KPMG LETTERHEAD]

                            INDEPENDENT AUDITORS' REPORT

The Board of Directors
HVL Parent Incorporated and Subsidiary:

We have audited the accompanying consolidated balance sheets of HVL Parent
Incorporated and subsidiary (the Company) as of September 30, 2005 and 2004
and the related consolidated statements of operations and comprehensive
income, stockholders' equity, and cash flows for the years then ended. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these consolidated
financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States of America. Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the
financial statements are free of material misstatement. An audit includes
consideration of internal control over financial reporting as a basis for
designing audit procedures that are appropriate in the circumstances, but not
for the purpose of expressing an opinion on the effectiveness of the Company's
internal control over financial reporting. Accordingly, we express no such
opinion. 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. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of HVL
Parent Incorporated and subsidiary as of September 30, 2005 and 2004 and the
results of their operations and their cash flows for the years then ended, in
conformity with accounting principles generally accepted in the United States
of America.

                     HVL PARENT INCORPORATED AND SUBSIDIARY
                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     (a) DESCRIPTION OF BUSINESS

         HVL Parent Incorporated and subsidiary (the Company) is a manufacturer
         and distributor of quality nutritional supplements with customers
         worldwide. The Company's business activity is primarily with
         alternative health care providers and distributors.

     (b) PRINCIPLES OF CONSOLIDATION

         The accompanying consolidated financial statements, presented in United
         States dollars, include the consolidated accounts of HVL Parent
         Incorporated (HVL) and its wholly owned subsidiary HVL, Incorporated
         (Inc.); Inc.'s nonincorporated trading divisions: Douglas
         Laboratories, Professional Series, and Doctor's Care and its wholly
         owned subsidiaries: Hi-Vidomin Laboratories, Inc of Delaware, HVL -
         FSC, Inc., Douglas Laboratories Europe, B.V., and Advanced Medical
         Nutrition, Inc., (AMNI). All intercompany balances and transactions
         have been eliminated. The consolidated group is herein referred to as
         "the Company".

     (c) REVENUE RECOGNITION

         The Company recognizes revenue when products are shipped and the
         customer takes ownership and assumes risk of loss, collection of the
         relevant receivable is probable, persuasive evidence of an arrangement
         exists and the sales price is fixed or determinable.

     (d) CASH AND CASH EQUIVALENTS

         The Company considers money market accounts with original maturities of
         less than three months as cash equivalents.

     (e) INVENTORIES

         Inventories are valued at the lower of cost (first-in, first-out) or
         market.

     (f) PROPERTY, PLANT, AND EQUIPMENT

         Property, plant, and equipment is stated at cost less accumulated
         depreciation. For financial statement purposes, the Company provides
         for depreciation using the straight-line method, based on the estimated
         useful lives of the related assets as follows:



                                                             YEARS
                                                             ------
                                                          
         Building and improvements                           5 - 40
         Equipment and machinery                             3 - 15
         Automobiles                                           5


         Maintenance and repairs, which are not considered to extend the useful
         lives of the assets, are charged to operations as incurred.
         Expenditures for additions and improvements are capitalized. Upon sale
         or retirement, the cost and related accumulated depreciation are
         removed from the accounts, and any resulting gains or losses are
         included in other income (expense) for the year.


                                       7                            (Continued)



                     HVL PARENT INCORPORATED AND SUBSIDIARY
                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

     (g) GOODWILL

         Goodwill represents the excess of the purchase price paid over the fair
         value of the net assets of businesses acquired. In accordance with
         Statement of Financial Accounting Standards (SFAS) No. 142, GOODWILL
         AND OTHER INTANGIBLE ASSETS, which was adopted on October 1, 2002 (the
         beginning of HVL's fiscal year 2003), goodwill and purchased
         intangibles with indefinite useful lives are no longer amortized but
         are reviewed periodically (at least annually) for impairment.
         Accordingly, HVL ceased to amortize approximately $10 million of net
         goodwill during fiscal 2003.

     (h) DEBT ISSUE COSTS

         The Company incurred legal, consulting, and bank fees related to the
         issuance of debt (note 4). These debt issue costs are amortized over
         the remaining life of the respective loans. Amortization expense was
         $205,308 and $259,641 during 2005 and 2004, respectively.

     (i) FOREIGN CURRENCY TRANSLATION

         Foreign exchange gains and losses as a result of translating a foreign
         entity's balance sheet from its functional currency into U.S. dollars
         are included as other comprehensive income in the consolidated
         statements of operations and comprehensive income. Accumulated other
         comprehensive income (loss) is reported in the consolidated statements
         of stockholders' equity. The functional currency for all of the
         Company's foreign operations is the Euro.

     (j) INCOME TAXES

         The Company accounts for income taxes in accordance with the provisions
         of Statement of Financial Accounting Standards No. 109, ACCOUNTING FOR
         INCOME TAXES (Statement 109). Under the asset and liability method of
         Statement 109, deferred tax assets and liabilities are recognized for
         the future tax consequences attributable to differences between the
         financial statement carrying amounts of existing assets and liabilities
         and their respective tax bases and operating loss and tax credit
         carryforwards. Deferred tax assets and liabilities are measured using
         enacted tax rates expected to apply to taxable income in the years in
         which those temporary differences are expected to be recovered or
         settled. Under Statement 109, the effect on deferred tax assets and
         liabilities of a change in tax rates is recognized in income in the
         period that includes the enactment date.

     (k) CREDIT AND PRODUCT CONCENTRATION RISK

         Sales of $11,702,181 or 17% of the Company's 2005 total net sales, were
         accounted for by one customer and one product. Accounts receivable
         relating to this customer were $1,150,550 as of September 30, 2005.

         Sales of $16,851,932 or 25% of the Company's 2004 total net sales were
         accounted for by one customer and one product. Accounts receivable
         relating to this customer were $2,151,258 as of September 30, 2004.

     (l) IMPAIRMENT OF LONG-LIVED ASSETS

         In accordance with SFAS No. 144, long-lived assets, such as property,
         plant, and equipment, are reviewed for impairment whenever events or
         changes in circumstances indicate that the carrying


                                       8                            (Continued)



                     HVL PARENT INCORPORATED AND SUBSIDIARY
                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

         amount of the asset may not be recoverable. Recoverability of assets to
         be held and used is measured by a comparison of the carrying amount of
         an asset to estimated undiscounted future cash flows expected to be
         generated by the asset. If the carrying amount of an asset exceeds its
         estimated future cash flows, an impairment charge is recognized by the
         amount by which the carrying amount of an asset exceeds the fair value
         of the asset.

     (m) STOCK-BASED COMPENSATION

         The Company accounts for its stock-based compensation plans under APB
         25. For stock options granted, the option price was not less than the
         fair market value of shares on the grant date, therefore, no
         compensation cost has been recognized. Had compensation cost been
         determined under the provisions of SFAS No. 123, the Company's net
         income would have been the following on a pro forma basis:



                                                               
         Net income, as reported                     $7,530,963      6,642,309
         Deduct total stock-based employee
           compensation expense determined under
           fair-value-based method for all awards,
           net of tax                                   (26,455)       (63,446)
                                                     ----------      ---------
         Pro forma net income                        $7,504,508      6,578,863
                                                     ----------      ---------
                                                     ----------      ---------


     (n) USE OF ESTIMATES

         The preparation of financial statements in conformity with generally
         accepted accounting principles requires management to make estimates
         and assumptions that affect the reported amounts of assets and
         liabilities and disclosure of contingent assets and liabilities at the
         date of the financial statements and the reported amounts of revenues
         and expenses during the reported period. Actual results could differ
         from those estimates.

     (o) RECLASSIFICATION

         Certain amounts in the 2004 financial statements have been reclassified
         to conform with the current year's presentation.


                                       9                            (Continued)

     The credit agreements for both the line-of-credit facility and the term
     loans contain restrictive convenants which, among other things, require the
     Company to maintain certain leverage and debt service ratios as well as
     certain levels of earnings and cash flows. The credit agreements have
     cross-collateral and cross-default provisions. The term loan agreement
     requires excess cash flows, as defined in the agreement, to be paid against
     the Term Loan A. The Company plans to finance such additional payment of
     $81,032 due for fiscal 2005 by borrowing against the revolving line of
     credit. The Company was in compliance with all covenants as of September
     30, 2005 and 2004. Accrued interest outstanding totaled $31,369 and $48,679
     as of September 30, 2005 and 2004, respectively.

(5)  STOCKHOLDERS' EQUITY

     During 2002, 2000, and 1998, the Board authorized the grant of stock
     options for 152,000, 332,500, and 424,000 shares, respectively, of Class A
     nonvoting common stock in accordance with the Company's Stock Option and
     Grant Plan. Of the 1998 stock options issued, 120,000 were for restricted
     shares (as defined below). All options were issued with an exercise price
     equal to fair market value at the date of grant, based on an appraisal. All
     options vest at a rate of 25% per year (although options on restricted
     shares may be exercised early subject to various restrictions) with
     immediate vesting upon the occurrence of certain defined transactions and
     expire ten years from the date of grant.

     Subsequent to issuance, the options were exercised for the 120,000 of
     restricted shares, bringing the total number of issued restricted shares of
     Class A nonvoting common stock to 240,000. These restricted total shares
     were issued to Company officers and members of management. Various
     restrictions exist as to the transferability of the shares. In addition,
     upon termination of the management member's employment with the Company,
     any nonvested shares must be sold back to the Company. During 1999, 94,000
     shares were repurchased by the Company. These shares were cancelled as
     part of the merger and reorganization during 2002. The restricted shares
     vest at the rate of 25% per year with 100% immediate vesting upon the
     occurrence of certain defined transactions.

     As of September 30, 2005, 494,000 of the outstanding options were vested
     and exercisable. All options granted in 1998 have a remaining contractual
     life of 2.75 years as of September 30, 2005. All options granted in 2000
     have a remaining contractual life of 4.6 years as of September 30, 2005.
     All options granted in 2002 have a remaining contractual life of 6.8 years
     as of September 30, 2005.

     The liquidation preference for the Series A and Series B convertible
     participating preferred stock is $9,208,000 and $792,000, respectively.
     Dividends are not cumulative, and the stock has voting rights. The stock
     has various conversion features into shares of common stock, Class A
     nonvoting common stock, and redeemable preferred stock, if 66-2/3% of the
     voting power of outstanding convertible participating preferred stock votes
     to have a conversion take place. The stock also has automatic conversion
     features in certain circumstances. The stock is redeemable by the Company
     on or after August 22, 2002, if 66-2/3% of the voting power of outstanding
     convertible participating preferred stock votes to have a conversion. The
     stock was redeemable prior to August 22, 2002, if certain "extraordinary
     transactions" (as defined) took place.

     The Series A and Series B redeemable preferred stock, if issued, would
     provide for 5% cumulative dividends.

     The Class C redeemable preferred stock provided for a cumulative dividend
     of $10 per share per annum commencing as of December 31, 1999, and the
     stock had no voting rights. The stock was redeemable by the Company on or
     after July 31, 2004 if a majority of the outstanding Class C redeemable
     preferred stock elected to have a redemption. The stock was redeemable
     prior to July 31, 2004, if certain "extraordinary transactions" (as
     defined) take place. During 2003, the bank issued an original,
     fully-executed consent with respect to the redemption of Class C redeemable
     preferred stock in the amount of $3,000,000. During 2003, the Class C
     redeemable preferred stock was redeemed in the amount of $3,000,000.

(6)  DEFINED CONTRIBUTION PLAN

     The Company sponsors a defined contribution 401(k) and profit sharing plan
     covering substantially all of its employees who have met certain
     eligibility requirements. Employees are allowed to contribute up to 15% of
     their compensation for the plan year to the 401(k) plan. The Company's
     matching contributions to the 401(k) plan as well as the contributions to
     the profit sharing plan are at the discretion of the board of directors and
     are allocated at 50% of the first 10% of the contributions made by each
     employee. Matching contributions to the 401(k) plan were $143,298 and
     $133,136 in 2005 and 2004, respectively.

(7)  LITIGATION AND CLAIMS

     The Company is party to various ongoing, pending, and threatened litigation
     along with other contingencies arising out of the normal course of
     business. Certain of these claims are against a major customer for product
     liability to which the Company has been named as a co-defendant. The
     ultimate disposition of these claims cannot be determined at this time.
     Management believes that these claims, when resolved, will not have any
     material adverse effect on the consolidated financial position or results
     of operations of the Company.

                     HVL PARENT INCORPORATED AND SUBSIDIARY
                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

     In assessing the recoverability of deferred tax assets, management
     considers whether it is more likely than not that some portion or all of
     the deferred tax assets will not be realized. The ultimate realization of
     deferred tax assets is dependent upon the generation of future taxable
     income during the periods in which those temporary differences become
     deductible. Management considers the scheduled reversal of deferred tax
     liabilities, projected future taxable income, and tax planning strategies
     in making this assessment.

     It is the Company's intention to continue to reinvest the undistributed
     earnings of its foreign subsidiaries; and, as such, no provision has been
     made for U.S. taxes on $2,545,000 of cumulative undistributed earnings of
     these foreign subsidiaries. Determination of the potential deferred tax
     liability is not practicable as foreign tax credits are expected to be
     available to offset any U.S. tax if and when these earnings are
     distributed.

     The provision for income taxes allocated to pretax income differs from tax
     calculated by applying the U.S. statutory federal income tax rate to pretax
     income due principally to state income taxes, net of the federal income tax
     benefit, foreign income taxed at rates other than the federal income tax
     rate, nondeductible expenses, extraterritorial income exclusion, and
     research and development tax credits.

     There was no tax expense or benefit allocated to the components of
     comprehensive income.

(9)  LEASING ARRANGEMENTS

     The Company leases various facilities, equipment, and vehicles through
     noncancelable operating leases. Approximate future minimum lease
     obligations under the noncancelable operating leases are as follows:



                                                        
         Year ending September 30:
           2006                                            $1,160,926
           2007                                             1,010,729
           2008                                               635,790
           2009                                                 9,422
           2010 and thereafter                                      -
                                                           ----------
                                                           $2,816,867
                                                           ----------
                                                           ----------


     The total rent and lease expense charged to operations was approximately
     $1,284,824 and $1,521,412 in 2005 and 2004, respectively.

(10) RESEARCH AND DEVELOPMENT

     In the course of normal operations, the Company routinely incurs various
     costs that are related to the development and testing of new products. The
     total research and development expense charged to operations was
     approximately $1,540,083 and $1,482,953 in 2005 and 2004, respectively.

(11) RELATED PARTY TRANSACTIONS

     The Company conducts its manufacturing operations at facilities leased from
     one of the Company's major stockholders. The lease, accounted for as an
     operating lease, provides for an approximate annual base rent of $764,000.
     The lease expires on May 31, 2008.


                                      15                            (Continued)

                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

(12) NOTES RECEIVABLE FOR SHARES SOLD

     Certain employees exercised their options to purchase Class A nonvoting
     common stock in exchange for an interest-bearing note (5.9%) secured by the
     shares. The principal balance and any unpaid interest shall be due and
     payable on the earlier of July 6, 2008 or when the related shares are
     redeemed. The outstanding principal balances of these notes amounted to
     $132,592 as of September 30, 2005 and 2004 and are classified as a
     reduction of stockholders' equity.

(13) SUBSEQUENT EVENTS

     In August 2005, the Company signed a non-binding letter of intent to sell
     all of the outstanding stock of the Company to Atrium Biotechnologies, Inc.
     (Atrium). As a result of this transaction, the outstanding debt of the
     Company will be paid in full, the shareholders of the Company will receive
     consideration in cash and shares of Atrium common stock, and the Company
     will become a wholly-owned subsidiary of Atrium.

     Subsequent to the balance sheet date, on December 8, 2005, all of the
     outstanding shares of common stock, common stock Class A nonvoting, and
     Series A and Series B convertible participating preferred stock were
     acquired by Atrium Biotechnologies, Inc. (Atrium). Atrium paid
     approximately $94,000,000 for the Company, of which approximately
     $9,000,000 was used to pay the balances outstanding on the revolving line
     of credit, term loan A, and term loan B (see note 4), and to pay for legal
     expenses related to the sale. Approximately $7,000,000 of the proceeds was
     placed in escrow pending resolution of various open items. Upon settlement
     of such open items, the remaining escrow amounts will be distributed to the
     stockholders of the Company. The remaining $78,000,000 was distributed to
     the stockholders of the Company based on their pro rata ownership after
     satisfaction of the liquidation preference related to the Series A and
     Series B convertible participating preferred stock (see note 5). The
     distribution to the stockholders of the Company consists of approximately
     $69,000,000 in cash and approximately $9,000,000 in shares of Atrium for
     certain of the stockholders.

     The balances outstanding on the revolving line of credit, term loan A, and
     term loan B were paid in full subsequent to the balance sheet date.

     As a result of this transaction, the Company became a wholly owned
     subsidiary of Atrium effective December 8, 2005.

(14) RECONCILIATION OF UNITED STATES AND CANADIAN GENERALLY ACCEPTED ACCOUNTING
     PRINCIPLES

     The financial statements of the Company have been prepared in accordance
     with accounting principles generally accepted in the United States of
     America (US GAAP). For the year ended September 30, 2005 and 2004, these
     principles do not differ materially from Canadian generally accepted
     accounting principles (Canadian GAAP) except:


                                      16                            (Continued)



                     HVL PARENT INCORPORATED AND SUBSIDIARY
                   Notes to Consolidated Financial Statements
                           September 30, 2005 and 2004

     The Series A and Series B convertible participating preferred stock is
     convertible, at the option of the holder, into redeemable preferred stock.
     Therefore, pursuant to Canadian GAAP, the Series A and Series B convertible
     participating preferred stock is classified as a current liability. For US
     GAAP purposes, the Series A and Series B convertible participating
     preferred stock is classified as equity. In accordance with Canadian GAAP,
     the balance sheet would reflect an increase in current liabilities of
     $10,000,000 and an equivalent decrease in additional paid-in capital in
     stockholders' equity. The consolidated statement of operations and
     comprehensive income and consolidated statement of cash flows for the years
     ended September 30, 2005 and 2004 would not differ under Canadian GAAP.

AETERNA ZENTARIS INC.

                                      18



                               COMPILATION REPORT

TO THE DIRECTORS
AETERNA ZENTARIS INC.

We have read the accompanying unaudited consolidated pro forma balance sheet of
AETERNA ZENTARIS INC. (the "Company") as at September 30, 2005 and the unaudited
consolidated pro forma statement of earnings for the nine-month period ended
September 30, 2005 and the year ended December 31, 2004, and have performed the
following procedures:

1.   Concerning the unaudited consolidated pro forma balance sheet as at
     September 30, 2005:

     o   Compared and recalculated the figures in the column captioned "AEterna
         Zentaris" to the unaudited consolidated balance sheet of the Company as
         at September 30, 2005, translated from Canadian dollars into US dollars
         using the appropriate CAN to US dollars exchange rate as at
         September 30, 2005 and found them to be in agreement;

     o   Compared the figures in the column captioned "Douglas" to the audited
         consolidated balance sheet of HVL Parent Incorporated and subsidiary
         ("Douglas") as at September 30, 2005, taking into account the US to
         Canadian GAAP difference described in the notes thereto, and found them
         to be in agreement.

2.   Concerning the unaudited consolidated pro forma statement of earnings for
     the nine-month period ended September 30, 2005:

     o   Compared and recalculated the figures in the column captioned "AEterna
         Zentaris" to the unaudited consolidated statement of earnings of the
         Company for the nine-month period ended September 30, 2005, translated
         from Canadian into US dollars using the appropriate CAN to US dollars
         average exchange rate for that period and found them to be in
         agreement;

     o   Compared the figures in the column captioned "Douglas - Year ended
         September 30, 2005" to the audited statement of earnings of Douglas for
         the year ended September 30, 2005, and found them to be in agreement;

     o   Compared the figures in the column captioned "Douglas - Three-month
         period ended December 31, 2004" to the unaudited internal statement of
         earnings of Douglas, for the three-month period ended December 31,
         2004, and found them to be in agreement.

3.   Concerning the unaudited consolidated pro forma statement of earnings for
     the year ended December 31, 2004:

     o   Compared and recalculated the figures in the column captioned "AEterna
         Zentaris" to the audited consolidated statement of earnings of the
         Company for the year ended December 31, 2004, translated from CAN into
         US dollars using the appropriate CAN to US dollars average exchange
         rate for that year and found them to be in agreement;

     o   Compared the figures in the column captioned "Douglas" to the audited
         statement of earnings of Douglas, for the year ended September 30,
         2004, and found them to be in agreement;


                                      19



4.   Made enquiries of certain officials of the Company who have responsibility
     for financial and accounting matters about:

     (a)  the basis for determination of the pro forma adjustments; and

     (b)  whether the consolidated pro forma financial statements comply as to
          form in all material respects with Canadian generally accepted
          accounting principles.

     The officials:

     (a)  described to us the basis for determination of the pro forma
          adjustments; and

     (b)  stated that the consolidated pro forma financial statements comply as
          to form in all material respects with Canadian generally accepted
          accounting principles.

5.   Read the notes to the consolidated pro forma financial statements, and
     found them to be consistent with the basis described to us for
     determination of the pro forma adjustments.

6.   Recalculated the application of the pro forma adjustments to the aggregate
     of the amounts in the columns captioned "AEterna Zentaris" and "Douglas",
     and found the amounts in the column captioned "AEterna Zentaris Pro forma"
     to be arithmetically correct.

The consolidated pro forma financial statements are based on management
assumptions and adjustments which are inherently subjective. The foregoing
procedures are substantially less than either an audit or a review, the
objective of which is the expression of assurance with respect to management's
assumptions, the pro forma adjustments and the application of the adjustments to
the historical financial information. Accordingly, we express no such assurance.
The foregoing procedures would not necessarily reveal matters of significance to
the consolidated pro forma financial statements, and we therefore make no
representation about the sufficiency of the procedures for the purposes of a
reader of such financial statements.

              NOTES TO CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
                      (Unaudited - See Compilation Report)
                     (expressed in thousands of US dollars)

1.   BASIS OF PRESENTATION

     The unaudited consolidated pro forma financial statements of AEterna
     Zentaris Inc. (the "Company") have been prepared in accordance with
     Canadian generally accepted accounting principles to give effect to the
     transactions described below as if they had occurred on September 30, 2005
     for the unaudited consolidated pro forma balance sheet and on January 1,
     2005 or January 1, 2004 for the unaudited consolidated pro forma statement
     of earnings.

     On December 8, 2005, the Company's subsidiary, Atrium Biotechnologies Inc.
     ("Atrium"), acquired all of the outstanding shares of HVL Parent
     Incorporated ("Douglas") whose main brand is Douglas Laboratories. This
     company markets health and nutrition products through healthcare
     practitioners mainly in the United States.

     This acquisition was made for a total consideration of $86,922,000 of which
     an amount of $75,365,000, including all acquisition-related costs, was paid
     in cash and $8,632,000 was paid by Atrium's subordinate voting shares
     issued to certain Douglas management shareholders at the price of CAN$10.95
     per share. The cash portion came from cash on hand and from the newly
     renegotiated revolving credit facility.

     This acquisition has been accounted for using the purchase method whereby
     the purchase price was allocated between the assets acquired and
     liabilities assumed based on management's estimate of the fair value on the
     date of acquisition. The excess of the price over the net identifiable
     tangible assets acquired has been included in the identifiable and
     non-identifiable intangible assets according to management's best estimate.
     The purchased price allocation will be finalized upon the reception of an
     independent valuation report.

     On November 8, 2005, Atrium amended its revolving credit facility, to
     increase the authorized amount from $64,488,000 (CAN$75,000,000) to
     $107,481,000 (CAN$125,000,000) and concluded in the same period an interest
     swap for an amount of $43,003,000 (CAN$50,000,000) converting a variable
     interest rate to a fixed interest rate.

     The unaudited consolidated pro forma balance sheet as at September 30, 2005
     has been prepared by combining the unaudited consolidated balance sheet of
     AEterna Zentaris as at September 30, 2005 translated from CAN to US dollars
     using the appropriate exchange rate stated below and the audited
     consolidated balance sheet of Douglas as at September 30, 2005 prepared in
     accordance with accounting principles accepted in the United States
     (U.S.GAAP) and taking into account the reconciliation to Canadian Generally
     Accepted Accounting Principles (CAN GAAP) disclosed in Note 14 thereto. The
     unaudited consolidated pro forma statement of earnings for the nine-month
     period ended September 30, 2005 has been prepared by combining the
     unaudited consolidated statement of earnings for the nine-month period
     ended September 30, 2005 of the Company, translated from CAN to US dollars
     using the appropriate exchange rate stated below, plus the Douglas audited
     consolidated statement of earnings for the year ended September 30, 2005
     less the Douglas internal unaudited consolidated statement of earnings for
     the three-month period ended December 31, 2004. As indicated in note 14 to
     the audited financial statements of Douglas, no adjustments are necessary
     from U.S.GAAP to CAN GAAP in the statements of earnings for the periods
     presented in such financial statements. The unaudited consolidated pro
     forma statement of earnings for the year ended December 31, 2004 has been
     prepared by combining the audited consolidated statement of earnings of the
     Company for the same period, translated from CAN to US dollars using the
     appropriate exchange rate stated below and the audited statement of
     earnings of Douglas for the year ended September 30, 2004.

              NOTES TO CONSOLIDATED PRO FORMA FINANCIAL STATEMENTS
                      (Unaudited - See Compilation Report)
                     (expressed in thousands of US dollars)

In December 2005, the Company decided to change its reporting currency from
Canadian dollars to US dollars to provide more relevant information considering
its predominant operations in the United States and its US dollar denominated
debt. Accordingly, the unaudited consolidated balance sheet of the Company as at
September 30, 2005, the unaudited consolidated statement of earnings for the
nine-month period ended September 30, 2005 and the audited consolidated
statement of earnings ended December 31, 2004 of the Company had been translated
to US dollars using the current rate method using the exchange rates disclosed
below. Under this method, assets and liabilities are translated into US dollars
using the exchange rate in effect at the balance sheet date. Revenues and
expenses are translated at the average rate in effect during the period. Gains
and losses are included in cumulative translation adjustments account in the
shareholders' equity. The functional currencies of the Company and each of its
subsidiaries remained unchanged.


                                                                       
Rate as at September 30, 2005                                             1.1627
Average rate for the nine-month period ended September 30, 2005           1.2240
Average rate for 2004                                                     1.3015


The unaudited consolidated pro forma financial statements should be read in
conjunction with the audited financial statements of the Company for the year
ended December 31, 2004 with the audited financial statements of Douglas for the
year ended September 30, 2005 and 2004 incorporated in the Business Acquisition
Report.

The unaudited consolidated pro forma financial statements have been prepared for
illustrative purposes only and are based on the assumptions set forth in the
accompanying notes to such statements. These financial statements are not
necessarily indicative of the operating results that would have been obtained or
the financial position that would have prevailed had the applicable transactions
actually taken place on the date indicated or of actual operating results or
financial position of the stand-alone or combined entities. The pro forma
adjustments are based on currently available information and management's
estimates and assumptions. Actual adjustments will differ from the pro forma

                            (expressed in US dollars)


     FINANCING OF THE ACQUISITION OF DOUGLAS

     (f)  This acquisition was financed by Atrium's amended revolving credit
          facility. For the pro forma, the old debt of Douglas totalling
          $10,225,000 (short term of $516,000 and long-term of $9,709,000) has
          been repaid and an increase of Atrium's amended revolving credit
          facility has been recorded for a total amount of $88,515,000. An
          interest rate of 6.27 % has been used, which is the current rate of
          borrowing under this revolving credit facility as of December 31,
          2005. This increase of long term debt, taking into account the
          reimbursement of the old Douglas debt by Atrium's amended credit
          facility produces a net interest expense increase of $3,802,000 in the
          pro forma consolidated statement of earnings for the nine-month period
          ended September 30, 2005 and $5,062,000 for the year ended December
          31, 2004.

     (g)  The interest expense adjustment takes into account the amortization
          related to financing fees. The old debt of Douglas related deferred
          financing costs totalling $273,000 has not been considered in the
          purchased price allocation. For the new amended credit facility, the
          financing cost totals $719,000 and is amortized over the new revolving
          credit facility period of 3 years. An amortization expense totalling
          $180,000 for the nine-month period ended September 30, 2005 and
          $240,000 for the year ended December 31, 2004 is accounted for in the
          pro forma consolidated statement of earnings as interest expense. The
          net increase of the deferred financing costs is therefore $446,000 for
          the adjustment in the pro forma consolidated balance sheet as of
          September 30, 2005.

     (h)  The income tax expense has been adjusted by of $1,595,000 for the
          nine-month period ended September 30, 2005 and of $2,125,000 for the
          year ended December 31, 2004 to reflect the increase of interest
          expense deductible for income tax purposes and the tax effect on
          amortization of intangible assets with finite lives.

     RECLASSIFICATION OF DEPRECIATION

     (i)  The depreciation included in the cost of goods of Douglas has been
          reclassified on the line Depreciation of the pro forma consolidated
          statements of earnings to reflect the same presentation used by the
          Company.

     GAIN ON DILUTION

     (j)  Pursuant to the issuance of Atrium's subordinate voting shares, a gain
          on dilution of investments was recognized in the balance sheet and due
          to the non-recurring nature, the gain on dilution was not reflected in
          the proforma statements of earnings.
