NEWS RELEASE

The dismissal of the litigation follows IntelGenx' previous announcement on January 4th, 2011 that the court had ruled in favor of IntelGenx regarding claim construction for the two patent terms at issue in the patent infringement action brought forward by Biovail under the Drug Price Competition and Patent Term Restoration Act ("Hatch-Waxman Act"). The ruling arose from a special proceeding required under U.S. patent law called a "Markman Hearing" where both sides presented to the court their arguments on how they believed the patent terms at issue should be interpreted. Subsequent to the ruling on the Markman Hearing, Biovail agreed to dismissal of the action.

"The litigation was a major obstacle in our partnership discussions for CPI-300, so we are delighted to have this legal process behind us," commented Horst Zerbe, President and CEO of IntelGenx. "We are in the final steps of accumulating the data necessary to address FDA's questions from the Complete Response Letter and submit our response to the Agency in the coming months."

About CPI-300

CPI-300 is a novel, high strength formulation of Bupropion hydrochloride ("HCl"), the active ingredient in Wellbutrin XL®. CPI-300 would be the only single pill, high strength, formulation of Bupropion hydrochloride on the market. At present, patients requiring a high dosage are prescribed multiples of the lower strengths of HCl tablets.
