BIOVAIL PROVIDES UPDATE ON SHARE REPURCHASE PROGRAM

TORONTO, Canada, June 13, 2008 – Biovail Corporation (NYSE, TSX: BVF) today announced that, as of June 12, 2008, the Company has purchased over 1,000,000 of its common shares under its previously announced share repurchase program. Open-market purchases continue under the program.

On May 8, 2008, Biovail announced that the Company’s Board of Directors had approved a share repurchase program of up to 14,000,000 common shares, representing approximately 10% of the Company’s public float (as defined by applicable rules). The share repurchase program was launched on June 2, 2008 and will terminate on June 1, 2009 or upon such time as Biovail completes its purchases.

Under the share repurchase program, Biovail may repurchase shares for cash on the open market from time to time, if it is considered advisable, through the facilities of the New York Stock Exchange and, following additional filings, the Toronto Stock Exchange. The specific timing and amount of share repurchases vary based on market conditions, regulatory requirements and other factors. The share repurchases are funded using Biovail’s existing cash resources. The program does not require Biovail to repurchase a minimum number of shares, and it may be modified, suspended or terminated at any time without prior notice. All common shares purchased by Biovail under this program will be cancelled. Biovail’s Board of Directors believes that such purchases are in the best interests of the Company and are a desirable use of corporate funds.
