(1)	On November 27, 2012, Patheon Inc. (the "Company") issued, to each holder of record as of such date, subscription rights to acquire additional restricted voting shares of the Company (the "Rights Offering"). On December 18, 2012, the reporting person fully exercised his basic subscription privilege to purchase 87,348 restricted voting shares. In addition, the reporting person also exercised his over-subscription privilege to purchase additional restricted voting shares unclaimed by other rights holders. Following the expiration of the Rights Offering on December 28, 2012, the reporting person was allocated an additional 8,704 shares as a result of the exercise of his over-subscription privilege. Accordingly, as a result of the reporting person's participation in the Rights Offering, the reporting person will be issued a total of 96,052 restricted voting shares.
(2)	The subscription price was converted from C$3.19 based on the December 18, 2012 closing rate of exchange of 0.9856 Canadian dollars per U.S. dollars as quoted by Reuters.
