The accrual for discounts amounting to a $ CONFIDENTIAL TREATMENT REQUESTED BY
THE COMPANY [C2] as of September 30, 2004 and $ CONFIDENTIAL TREATMENT REQUESTED
BY THE COMPANY [C3] as of September 30, 2003 is reported in the balance sheet
separately from the other accruals listed above. The provisions for product
returns, chargebacks, contract rebates and discounts are based on estimates
derived from historical experience. Quarterly, the Company validates the ending
balance for each provision with an estimate based on historical experience and
updated to include the most recent transactions.

<Page>

CONFIDENTIAL TREATMENT REQUESTED BY THE COMPANY [C4], we consider historical
experience as the most reliable and therefore most appropriate information to
estimate product returns, chargebacks, contract rebates and discounts. Because
we believe our historical experience is our most reliable information at this
time, we believe that calculating the accruals using a different method or
assumptions could be misleading.

     (b)  EXPLAIN TO US THE FACTORS THAT YOU CONSIDER IN ESTIMATING EACH ACCRUAL
          SUCH AS HISTORICAL RETURN OF PRODUCTS, LEVELS OF INVENTORY IN THE
          DISTRIBUTION CHANNEL, ESTIMATED REMAINING SHELF LIFE, PRICE CHANGES
          FROM COMPETITORS, AND INTRODUCTIONS OF GENERICS AND/OR NEW PRODUCTS.

RESPONSE:

Factors considered in estimating each accrual:

   i)   For product returns, CONFIDENTIAL TREATMENT REQUESTED BY THE COMPANY
        [C5].

   ii)  Chargebacks are paid by Axcan to the wholesalers CONFIDENTIAL TREATMENT
        REQUESTED BY THE COMPANY [C6].

   iii) Contract rebates are issued CONFIDENTIAL TREATMENT REQUESTED BY THE
        COMPANY [C7].

   iv)  The accrual for discounts is calculated using the assumption that
        CONFIDENTIAL TREATMENT REQUESTED BY THE COMPANY [C8].

     (c)  TO THE EXTENT THAT INFORMATION YOU CONSIDER IN (b) IS QUANTIFIABLE,
          TELL US BOTH THE QUANTITATIVE AND QUALITATIVE INFORMATION AND DISCUSS
          TO WHAT EXTENT INFORMATION IS FROM EXTERNAL SOURCES (E.G.,
          END-CUSTOMER PRESCRIPTION DEMAND, THIRD-PARTY MARKET RESEARCH DATA
          COMPARING WHOLESALER INVENTORY LEVELS TO END-CUSTOMER DEMAND). FOR
          EXAMPLE, IN DISCUSSING YOUR ESTIMATE OF PRODUCT THAT MAY BE RETURNED,
          TELL US BY PRODUCT AND IN TABULAR FORMAT, THE TOTAL AMOUNT OF PRODUCT
          IN SALES DOLLARS THAT COULD POTENTIALLY BE RETURNED AS OF THE BALANCE
          SHEET DATE AND DISAGGREGATED BY EXPIRATION PERIOD.

RESPONSE:

Most of the information used to establish the accruals is internal and based on
historical experience. Management considers such information to be the most
reliable available.

CONFIDENTIAL TREATMENT REQUESTED BY THE COMPANY [C9].

     (d)  IF APPLICABLE, TELL US ABOUT ANY SHIPMENTS MADE AS A RESULT OF
          INCENTIVES AND/OR IN EXCESS OF YOUR CUSTOMER'S ORDINARY COURSE OF
          BUSINESS INVENTORY LEVEL. DISCUSS YOUR REVENUE RECOGNITION POLICY FOR
          SUCH SHIPMENTS.

<Page>

RESPONSE:

As already discussed in our MD&A, "wholesaler buying patterns, including a
tendency to increase inventory levels prior to an anticipated or announced price
increase, affect Axcan's operating results by shifting revenue between quarters.
To maintain good relations with wholesalers, Axcan typically gives prior notice
of price increases."

CONFIDENTIAL TREATMENT REQUESTED BY THE COMPANY [C10].

As mentioned in our MD&A, under "Revenue Recognition", revenue is recognized
when the product is shipped to the Company's customer, provided the Company has
not retained any significant risks of ownership or future obligations with
respect to the product shipped. Revenue from product sales is recognized net of
sales discounts, allowances, returns, rebates and chargebacks.

     (e)  PROVIDE US WITH A ROLL FORWARD OF THE ACCRUAL OF EACH ESTIMATE FOR
          EACH PERIOD PRESENTED SHOWING THE FOLLOWING:
          -  BEGINNING BALANCE,
          -  CURRENT PROVISION RELATED TO SALES MADE IN CURRENT PERIOD,
          -  CURRENT PROVISION RELATED TO SALES MADE IN PRIOR PERIODS,
          -  ACTUAL RETURNS OR CREDITS IN CURRENT PERIOD RELATED TO SALES MADE
          IN CURRENT PERIOD,
          -  ACTUAL RETURNS OR CREDITS IN CURRENT PERIOD RELATED TO SALES MADE
          IN PRIOR PERIODS, AND
          -  ENDING BALANCE.

The same method was used to estimate accruals for product returns, chargebacks,
contract rebates and discounts during the last three fiscal years, and changes
in our estimates of these items had a negligible impact on the company's
revenues and operations.

     (g)  TELL US WHY YOU DID NOT PROVIDE THE ABOVE INFORMATION IN YOUR MD&A TO
          GIVE INVESTORS INFORMATION ABOUT THESE CRITICAL ACCOUNTING ESTIMATES.

RESPONSE:

The Company disclosed in note 14 to consolidated financial statements the amount
of accrued contract rebates, product returns and chargebacks at year end. In
order to enhance the Company's disclosures, we will include in our next 40-F
filing a discussion on contract rebates, product returns and chargebacks
deducted against revenue, their fluctuations and basis of calculation. We do not
believe that the detailed information regarding the deductions from gross
revenue provided above is material, and consequently, we believe that providing
this level of detail is not useful to investors.

     OF TOTAL ASSETS. WE BELIEVE YOUR CRITICAL ACCOUNTING ESTIMATES ABOUT THESE
     ASSETS COULD BE IMPROVED TO PROVIDE MORE TRANSPARENT, RELEVANT, AND USEFUL
     DISCLOSURES, ESPECIALLY CONSIDERING THE SIGNIFICANCE OF THESE ASSETS TO
     YOUR BALANCE SHEET AND OPERATIONS. PLEASE TELL US THE FOLLOWING AS IT
     RELATES TO YOUR INTANGIBLES.

     (a)  BY SIGNIFICANT PRODUCT AND BY THERAPEUTIC CATEGORY IN THE CASE OF
          INSIGNIFICANT PRODUCTS:
          - THE GROSS CARRYING AMOUNT AND ACCUMULATED AMORTIZATION AS OF
          YEAR-END;
          - AMORTIZATION PERIOD USED;
          - COMPARISON OF THE REMAINING PATENT LIFE FOR PATENTS UNDERLYING THE
          TRADEMARKS, LICENSES, AND MANUFACTURING RIGHTS TO THAT OF THE
          REMAINING ESTIMATED USEFUL LIFE USED TO AMORTIZE THE INTANGIBLE. IF
          APPLICABLE, EXPLAIN THE REASON FOR DIFFERENCES;
          - YOUR METHOD OF AMORTIZATION, SUCH AS STRAIGHT-LINE OR ACCELERATED.
          IF YOU USE STRAIGHT-LINE, DISCLOSE THE BASIS FOR USING STRAIGHT-LINE
          RATHER THAN AN ACCELERATED METHOD OF AMORTIZATION (E.G., CONSIDERING
          THE LIKELY ENTRY OF GENERIC COMPETITION AND OTHER FACTORS);

For most acquisitions of products already on the market, the trademark or brand
represented most of the value. Trademarks or brands are amortized over their
useful life on a straight-line basis, management re-evaluates the remaining
useful life annually and it is possible that the remaining life could be
reviewed.

In addition, management evaluates the value of intangible assets annually, by
comparing the carrying value to the future benefits of the company's activities
or the expected sales of pharmaceutical products. Should there be a permanent
impairment in value or if unamortized amount exceeds recoverable amounts, a
write-down will be recognized for the current year.

The Company choose to use straight-line amortization for the intangible assets
with a finite life because this method of amortization reflects, in the opinion
of the management, the pattern in which the intangible assets are used. See
comments in answer 2b) concerning the Company's products.

     (b)  PLEASE PROVIDE ANY OTHER QUANTITATIVE AND QUALITATIVE INFORMATION THAT
          YOU BELIEVE WOULD BE APPROPRIATE TO HELP US UNDERSTAND YOUR DISCLOSURE
          FOR THESE INTANGIBLE ASSETS; AND

RESPONSE:

The Company seeks well-established products that are not actively promoted by
larger pharmaceutical companies and that complement our existing portfolio or
could be used in conjunction with some of our existing products. For past
product acquisitions, intellectual property protection was limited and some
already had generic competition. The value of these products was more related to
our ability to maintain or increase sales focusing on gastroenterology, our main
market, leveraging our sales force, or adding a new indication or dosage form.
Therefore the remaining patent life was not a major criteria in the evaluation
of the useful life of the products.

     (c)  EXPLAIN TO US WHY YOU HAVE NOT PROVIDED THE ABOVE INFORMATION IN YOUR
          MD&A TO GIVE INVESTORS INFORMATION ABOUT THESE CRITICAL ACCOUNTING
          ESTIMATES.

RESPONSE:

The Company disclosed in note 11 to its consolidated financial statements the
amount of trademarks, trademark licenses and manufacturing rights with a finite
life and the amount of trademarks, trademark licenses and manufacturing rights
with an indefinite life. The Company disclosed also the annual amortization
expenses for fiscal years 2005 through 2009 and the weighted-average remaining
amortization period of approximately 18 years.

As you can see in the table in answer 2 a), the information already disclosed
above gives the investors a fair view of the detailed information.

We did not include the more detailed information because we do not think that it
is material, and consequently, we believe that the inclusion of such information
is not useful to investors. We will however add a discussion on the choice of
the straight-line amortization method rather than the accelerated method of
amortization in our next annual financial statements.


                                                 Sincerely,
