Unilife Announces Dismissal of Shareholder Class Action Lawsuit

-            -             -

York, PA (January 23, 2014) Unilife Corporation (“Unilife”) (NASDAQ: UNIS, ASX: UNS) announced today that a recent shareholder class action lawsuit against the Company and certain corporate officers in the United States District Court for the Middle District of Pennsylvania alleging violations of federal securities laws was voluntarily dismissed by the plaintiff.

The notice of voluntary dismissal was filed by the plaintiff after no additional shareholders of the Company petitioned the court to serve as lead plaintiff in the lawsuit before the December 31, 2013 deadline.

As previously reported, the class action lawsuit was always considered to be frivolous and based mainly on the meritless allegations made by a former employee of the Company.
