                              BIOVAIL CORPORATION

            CONDENSED NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

        IN ACCORDANCE WITH U.S. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
      (TABULAR AMOUNTS EXCEPT PER SHARE DATA ARE EXPRESSED IN THOUSANDS OF
                                 U.S. DOLLARS)
                                  (UNAUDITED)

1.  SIGNIFICANT ACCOUNTING POLICIES

    BASIS OF PRESENTATION

    The accompanying unaudited consolidated financial statements have been
    prepared by the Company in U.S. dollars and in accordance with
    U.S. generally accepted accounting principles ("GAAP"). The interim
    financial statements have been prepared using accounting policies that are
    consistent with policies used in preparing the 2000 annual consolidated
    financial statements. Accordingly, these unaudited condensed notes to the
    consolidated financial statements should be read in conjunction with the
    audited consolidated financial statements and notes on Form 20-F for the
    year ended December 31, 2000. Certain of the prior year's interim figures
    have been reclassified to conform to the current interim period's
    presentation.

    In preparing the Company's consolidated financial statements, management is
    required to make estimates and assumptions that affect the reported amounts
    of assets and liabilities, the disclosure of contingent assets and
    liabilities at the date of the financial statements and the reported amounts
    of revenue and expenses during the reporting period. Actual results could
    differ from these estimates and the operating results for the interim
    periods presented are not necessarily indicative of the results expected for
    the full year.

2.  CHANGES IN ACCOUNTING POLICIES

    REVENUE RECOGNITION

    Non-refundable, up-front fees for access to the Company's proprietary
    technology in connection with certain research and development arrangements
    are deferred and recognized as revenue on a straight-line basis over the
    term of the relevant arrangement. License revenue is deferred and recognized
    on a straight-line basis over the license period. If there are future
    performance obligations of the Company, or contingent future events relating
    to the amounts received or receivable under license agreements, revenue
    attributable to these obligations or future events is deferred and
    recognized upon the completion of the specific event.

    In the fourth quarter of 2000, the Company implemented the provisions of the
    U.S. Securities and Exchange Commission's, Staff Accounting Bulletin
    No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements",
    retroactively to January 1, 2000, as required. Accordingly, the Company
    changed its method of accounting to that described above for up-front
    research and development, product license and certain other fees. The
    Company historically recognized these fees as revenues when all the
    conditions to payment had been met, and there were no further performance
    contingencies or conditions to the Company's receipt of payment. These fees
    were not creditable against future payments. At January 1, 2000, the
    cumulative effect of the change in accounting principle on prior years
    resulted in a charge of $43,500,000, which is included in the net loss for
    the three months ended March 31, 2000. The related deferred revenue
    recognized for the three months ended March 31, 2001 and 2000 was $1,575,000
    and $1,825,000, respectively.

    ACCOUNTING FOR DERIVATIVES

    The Company implemented the Financial Accounting Standards Board's,
    Statement of Financial Accounting Standard ("SFAS") No. 133, "Accounting for
    Derivative Instruments and Hedging Activities". SFAS No. 133 requires a
    company to recognize all derivative instruments as assets or liabilities in
    its balance sheet and to measure them at fair value. The adoption of SFAS
    No. 133 did not result in any cumulative effect adjustment in the
    consolidated statements of income (loss), and did not have a material impact
    on the Company's financial position or results of operation for the three
    months ended March 31, 2001.

8.  EARNINGS (LOSS) PER SHARE

    Earnings (loss) per share is determined in accordance with SFAS No. 128,
    "Earnings Per Share". Earnings (loss) per share is based on net income
    (loss). Basic earnings per share is computed using the weighted average
    number of common shares outstanding during the reporting period. Diluted
    earnings (loss) per share is computed after giving effect to the potentially
    dilutive warrants, stock options and convertible securities. The computation
    of basic and diluted earnings (loss) per share was as follows:

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
        IN ACCORDANCE WITH U.S. GENERALLY ACCEPTED ACCOUNTING PRINCIPLES
               (ALL DOLLAR AMOUNTS ARE EXPRESSED IN U.S. DOLLARS)

The following Management's Discussion and Analysis of Financial Condition and
Results of Operations ("MD&A") should be read in conjunction with the
accompanying unaudited consolidated financial statements and condensed notes
thereto. This MD&A should also be read in conjunction with the MD&A and audited
consolidated financial statements and notes thereto on Form 20-F for the year
ended December 31, 2000.

                                    OVERVIEW

    Our results for the first quarter 2001 reflected the impact of the strategic
business acquisitions completed during 2000. Most notably the increase in our
product sales reflected the addition of the Cardizem-Registered Trademark-
product line ("Cardizem-Registered Trademark-") which we acquired from Aventis
Pharmaceuticals Inc. ("Aventis"). Cardizem-Registered Trademark- is being
marketed in Canada through Crystaal, and in the United States through Biovail
Pharmaceuticals, Inc. ("Biovail Pharmaceuticals"), formerly DJ Pharma, Inc. ("DJ
Pharma") which we acquired in October 2000. In addition to
Cardizem-Registered Trademark-, our first quarter 2001 product sales included
the incremental revenue from Biovail Pharmaceuticals' existing product
portfolio. The decline in research and development revenue reflected our
December 2000 acquisition of Intelligent Polymers Limited ("Intelligent
Polymers") and its development pipeline of branded generic products, which we
were developing on their behalf prior to September 29, 2000.

    Our revenues are derived from sales of pharmaceutical products, providing
research and development services, and from royalties and license fees. Product
sales include sales of products developed and manufactured by us for our
licensees, direct marketing in Canada and the United States of proprietary and
in-licensed products, and revenue derived from product co-promotion. Research
and development revenues relate to product development activity on behalf of
third parties, and pharmaceutical contract research services. Royalties
primarily arise on sales of the products we developed. License fees are derived
from the license of our technologies or product rights.

                        CHANGES IN ACCOUNTING PRINCIPLES

REVENUE RECOGNITION

    We have adopted the U.S. Securities and Exchange Commission's ("SEC"), Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements", retroactively applied to January 1, 2000. Accordingly, we have
changed our revenue recognition accounting policy for up-front research and
development, product license and certain other fees. Historically, we had
recognized these fees as revenues when all the conditions to payment had been
met, and there were no further performance contingencies or conditions to our
receipt of payment. These fees were not creditable against future payments. At
January 1, 2000, the cumulative effect of the change in accounting principle on
prior years resulted in a charge of $43.5 million, which is included in the net
loss for the three months ended March 31, 2000. The related deferred revenue
recognized for the three months ended March 31, 2001 and 2000, was $1.6 million
and $1.8 million, respectively.

ACCOUNTING FOR DERIVATIVES

    We implemented the Financial Accounting Standards Board's, Statement of
Financial Accounting Standard ("SFAS") No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 requires a company to
recognize all derivative instruments as assets or liabilities in its balance
sheet and to measure them at fair value. The adoption of SFAS No. 133 did not
result in any cumulative effect adjustment in the consolidated statements of
income (loss), and did not have a material impact on our financial position or
results of operation for the three months ended March 31, 2001.

                                       11

                             RESULTS OF OPERATIONS

    Total revenue for the first quarter 2001 was $119.2 million, an increase of
$68.4 million or 134% from $50.8 million for the first quarter 2000. Income
before extraordinary item and cumulative effect of change in accounting
principle for the first quarter 2001 was $29.2 million, or diluted earnings per
share of $0.20, compared to $15.0 million, or diluted earnings per share of
$0.11, for the first quarter 2000. Income before extraordinary item and
cumulative effect of change in accounting principle and diluted earnings per
share increased by 95% and 81%, respectively for the first quarter 2001 compared
to the first quarter 2000.

    The results for the first quarter 2000 include charges of $20.0 million for
the premium paid to extinguish our 10 7/8% U.S. Dollar Senior Notes (the "Senior
Notes"), and $43.5 million for the cumulative effect of the adoption of
SAB 101.

                                    REVENUE

PRODUCT SALES

    Product sales for the first quarter 2001 were $111.9 million compared to
$35.9 million for the first quarter 2000, an increase of $76.0 million or 212%.
The increase in product sales was due to a combination of the contribution from
Cardizem-Registered Trademark-, incremental revenues from Biovail
Pharmaceuticals' Dura-Vent, Rondec and Cedax products, and strong sales from our
generic product portfolio, which were favourably impacted by the February 2001
launch of Procardia XL 30mg dosage and the 2000 launches of Voltaren XR, Adalat
CC 30mg and 60mg dosages, and Procardia XL 60mg dosage.

    Product sales were negatively impacted by lost sales of Biovail
Pharmaceuticals' Keftab product. On March 7, 2001, Eli Lilly & Company ("Eli
Lilly") announced a voluntary recall of Keftab tablets because of undefined
problems with stability. We believe Eli Lilly is responsible for manufacturing
and supplying acceptable products to us, as well as for the cost of the recall.

RESEARCH AND DEVELOPMENT

    Research and development revenue for the first quarter 2001 was
$1.6 million, a decline of $10.1 million or 87% from $11.7 million for the first
quarter 2000. This decline reflects our acquisition of Intelligent Polymers in
December 2000, and the elimination of revenue from development activities
performed on their behalf. We earned revenue of $9.7 million from Intelligent
Polymers in the first quarter of 2000.

ROYALTY AND LICENSING

    Net royalty and licensing revenue for the first quarter 2001 was
$5.7 million compared to $3.3 million for the first quarter 2000, an increase of
$2.4 million or 75%. In both quarters, most of our royalties were derived from
sales of Tiazac-Registered Trademark- to Forest Laboratories Inc. The increase
in the first quarter of 2001 reflected higher Tiazac-Registered Trademark-
product sales, and the inclusion of a royalty associated with sales of
Cardizem-Registered Trademark- by a third party.

                               OPERATING EXPENSES

COST OF GOODS SOLD AND GROSS MARGINS

    Cost of goods sold was $26.6 million for the first quarter 2001 compared to
$11.0 million for the first quarter 2000. The $15.6 million, or 141%, quarter
over quarter increase was the result of increased product sales volumes from the
additions of Cardizem-Registered Trademark-, Biovail Pharmaceuticals' products,
and generic product launches.

    Gross margins based on product sales for the first quarter 2001 and 2000
were 76% and 69%, respectively. Our gross margins are impacted quarter to
quarter by sales volumes, pricing, product mix and manufacturing volumes. The
increase in gross margin for the first quarter 2001 compared to the first
quarter 2000 reflected the positive impact of Cardizem-Registered Trademark-
sales, and the inclusion of Biovail Pharmaceuticals' directly marketed products.

                                       12

RESEARCH AND DEVELOPMENT

    Research and development expenses for the first quarter 2001 were
$11.4 million compared to $11.8 million for the first quarter 2000. Research and
development expenses reflected direct spending on the development of branded
generic and generic products, and rapid dissolve products utilizing our
FlashDose technology. The slight quarter over quarter decline in the research
and development expenses reflected a reduction in overhead costs at Biovail
Technologies Ltd., formerly Fuisz Technologies Ltd. ("Fuisz") following a period
of transition and integration in the first quarter of 2000.

SELLING, GENERAL AND ADMINISTRATIVE

    Selling, general and administrative expenses for the first quarter 2001 were
$36.9 million, an increase of $25.0 or 209% from $11.9 million for the first
quarter 2000. The increase in selling, general and administrative expenses
reflected the acquisitions of, and the related amortization expense associated
with, DJ Pharma and Cardizem-Registered Trademark-.

                              NON-OPERATING ITEMS

INTEREST EXPENSE

    For the first quarter 2001, net interest expense of $12.5 million was
comprised of interest expense of $13.1 million net of interest income of
$578,000, compared to net interest expense of $266,000 for the first quarter of
2000, comprised of interest expense of $4.2 million net of interest income of
$3.9 million.

    The increase in interest expense primarily reflected interest on advances
under our revolving term Senior Secured Credit Facility (the "Credit Facility")
and the amortization of the discount on the obligation to Aventis for
Cardizem-Registered Trademark-.

    The decrease in interest income reflected a decline in the average size of
our investment portfolio following the acquisitions of DJ Pharma and Intelligent
Polymers in the fourth quarter of 2000, and after the first quarterly instalment
payment to Aventis and repayments made under the Credit Facility in the first
quarter of 2001.

INCOME TAXES

    Our tax rate was affected by the relative profitability of our operations in
various foreign tax jurisdictions. We recorded provisions for income taxes of
$2.8 million and $813,000 in the first quarter of 2001 and 2000, respectively.
These provisions reflect effective tax rates on income before taxes, excluding
non-deductible amounts, of approximately 9% and 6% in the first quarter of 2001
and 2000, respectively. The low effective tax rate reflected that most of our
income was derived from foreign subsidiaries with lower statutory tax rates than
those that apply in Canada. The benefit of tax losses historically incurred by
our Canadian operations has not been recognized for accounting purposes to date.
With our acquisitions of DJ Pharma and Fuisz we have experienced some upward
movement in our effective tax rate, as these operations earn income
predominately in the United States.

EXTRAORDINARY ITEM

    The total consideration paid to repurchase our Senior Notes was
$141.0 million of which $16.0 million was an inducement premium to the holders.
As a result of this transaction, we replaced our high yield debt with
convertible debt at a significantly lower cost of borrowing. The extraordinary
item reported in the first quarter of 2000 included the premium paid, and
$4.0 million of deferred financing costs associated with the Senior Notes that
were written-off.

                                     EBITDA

    EBITDA, which is defined as earnings before interest, taxes, depreciation
and amortization, increased by $36.2 million or 168% to $57.8 million for the
first quarter 2001 from $21.6 million for the first quarter 2000.

                        LIQUIDITY AND CAPITAL RESOURCES

    At March 31, 2001, we had cash and cash equivalents of $49.6 million
compared to cash and cash equivalents of $125.1 million at December 31, 2000. In
December 2000, we arranged a $300 million Credit Facility that, subject to
certain covenants, permits us to borrow funds for general corporate purposes
including acquisitions.

    At March 31, 2001, we had total long-term obligations of $313.5 million,
including the current portion thereof. Long-term obligations consisted of
$133.9 million drawn on the Credit Facility, $122.9 million discounted amount
owing to Aventis for Cardizem-Registered Trademark-, $48.2 million discounted
amount owing to Elan Corporation, plc ("Elan") for the exclusive marketing
rights to generic Adalat CC 30mg, and $8.5 million of other obligations. At
December 31, 2000, we had $438.7 million of long-term obligations, including the
current portion thereof, which consisted of $210 million drawn on the Credit
Facility, $161.8 million discounted amount owing to Aventis, $58.1 million
discounted amount owing to Elan, and $8.8 million of other obligations.

    Also at March 31, 2001 and December 31, 2000, we had $300.0 million of
Convertible Subordinated Preferred Equivalent Debentures (the "Debentures")
outstanding, which are due March 31, 2025. The Debentures are convertible at any
time into our common shares at $30.337 per common share, and may be redeemed at
our option beginning on March 31, 2003 at prescribed redemption prices. We have
the special right to redeem the Debentures if the trading price of our common
shares equals or exceeds $45.505 on the New York Stock Exchange for a specified
period, subject to certain restrictions. Interest on the Debentures is payable
quarterly in arrears. Subject to certain conditions, we have the right to defer
the payment of interest for up to twenty consecutive quarters. Interest and
principal are payable in cash or, at our option, using the proceeds from the
sale of our common shares or other equity securities.

    At March 31, 2001, our working capital ratio was 0.7:1 compared to 0.9:1 at
December 31, 2000. This decline was primarily due to a lower cash and cash
equivalents balance reflecting repayments made under the Credit Facility.

    Cash provided by operating activities, after changes in non-cash operating
items, was $65.3 million for the first quarter 2001 compared to cash used in
operating activities of $2.0 million for the first quarter 2000. This increase
reflects net income, after adjustments for non-cash items, of $48.5 million for
the first quarter 2001 compared to $20.5 million in the first quarter 2000.
Changes in non-cash operating items provided cash of $16.9 million in the first
quarter of 2001, and used cash of $22.5 million in the first quarter of 2000.

    Net cash used in investing activities was $18.3 million for the first
quarter 2001 compared to cash provided by investing activities of $57.4 million
for the first quarter 2000. Additions to property, plant and equipment were
$13.0 million and $3.9 million in the first quarter of 2001 and 2000,
respectively. Additions in the first quarter of 2001 included the payment of the
remaining purchase price of $10 million for the Dorado, Puerto Rico,
pharmaceutical manufacturing facility. We settled $4.0 million of acquisition
costs related to Cardizem-Registered Trademark-, and acquired other product
rights for $10.0 million in the first quarter of 2001, offset by $8.8 million
recovered from Elan as a reduction to the minimum license payments otherwise
payable under the Adalat CC 30mg marketing agreement. The net activity in
short-term investments provided cash of $46.3 million in the first quarter of
2000. During 2000, as our short-term investments matured we generally converted
them into cash equivalents with original maturities of 90 days or less. In the
first quarter of 2000, we received proceeds of $17 million on the disposal of
Clonmel Healthcare Limited, a subsidiary of Fuisz.

    Net cash used in financing activities was $122.5 million for the first
quarter 2001 compared to cash provided by financing activities of
$242.2 million for the first quarter 2000. Proceeds from issue of common shares
on the exercise of stock options and through our Employee Stock Purchase Plan
were $7.4 million and $6.2 million for the first quarter of 2001 and 2000,
respectively. Net proceeds from the concurrent offering in March 2000 were
$96.1 million from the issue of common shares, and $290.3 million from the issue
of Debentures. A portion of these proceeds was used to repurchase our Senior
Notes for $141.0 million. In the first quarter of 2001, we repaid $76.1 million
under our Credit Facility, and $53.8 million of other long-term obligations,
including the first quarterly instalment to Aventis of $42.5 million and
$10.9 million to Elan. In the first quarter of 2000, we repaid the debt assumed
on the acquisition of Fuisz and other long-term obligations of $10.7 million. We
collected $1.3 million of the warrant subscription receivable in the first
quarter of 2000.

                                       14

    Overall, our cash and cash equivalents decreased by $75.6 million in the
first quarter of 2001, and increased by $297.6 million in the first quarter of
2000.

    We believe we have adequate capital resources and sources of financing to
support our ongoing operational and interest requirements, investment
objectives, and to meet our obligations as they become due. We believe we will
be able to raise additional capital, if necessary, to support our objectives.

           QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

    We are exposed to financial market risks, including changes in foreign
currency exchange rates, interest rates on investments and debt obligations and
equity market prices on long-term investments. We do not use derivative
financial instruments for speculative or trading purposes.

    Inflation has not had a significant impact on our results of operations.

FOREIGN CURRENCY RISK

    We operate internationally, however a substantial portion of our revenue and
expense activities and capital expenditures are transacted in U.S. dollars. Our
only other significant transactions are in Canadian dollars, and we do not
believe we have a material exposure to foreign currency risk because of the
relative stability of the Canadian dollar in relation to the U.S. dollar. A 10%
adverse change in foreign currency exchange rates would not have a material
effect on our consolidated results of operations, financial position, or cash
flows.

INTEREST RATE RISK

    The primary objective of our investment policy is the protection of
principal, and accordingly we invest in high-grade commercial paper and
U.S. government treasury bills with varying maturities, but typically less than
90 days. External independent fund administrators manage our investments. As it
is our intent and policy to hold these investments until maturity, we do not
have a material exposure to interest rate risk. Therefore, a 100 basis-point
adverse change in interest rates would not have a material effect on our
investment portfolio.

    We are exposed to interest rate risk on borrowings from our Credit Facility.
The Credit Facility bears interest based on LIBOR, U.S. dollar base rate,
Canadian dollar prime rate, or Canadian dollar Bankers' Acceptances. Based on
projected advances under the Credit Facility, a 100 basis-point adverse change
in interest rates would increase interest expense by approximately $2 million on
an annual basis. This risk is mitigated by our ability, at our option, to lock
in a rate of interest for a period of up to one year.

    The interest rate on our Debentures is fixed and therefore not subject to
interest rate risk. Likewise, the imputed rate of interest used to discount our
long-term obligations to Aventis and Elan is fixed and therefore not subject to
interest rate risk.

EQUITY MARKET PRICE RISK

    We are exposed to equity market price risks on our long-term,
available-for-sale investments in traded companies. We do not hold significant
investments in these types of securities, and therefore our equity market price
risk is not material. Therefore, a 10% adverse change in equity market prices
would not have a material effect on our financial position.

                           FORWARD LOOKING STATEMENTS

    To the extent any statements made in this document contain information that
is not historical, these statements are essentially forward looking and are
subject to risks and uncertainties, including the difficulty of predicting FDA
approvals, acceptance and demand for new pharmaceutical products, the impact of
competitive products and pricing, new product development and launch, reliance
on key strategic alliances, availability of raw materials, the regulatory
environment, fluctuations in operating results and other risks. Many risks and
uncertainties are inherent in the pharmaceutical industry; others are more
specific to our business. Many of the significant risks related to our business
are described in Item 1 of our Form 20-F filing with the SEC.
