Retains Wilson Sonsini as Counsel

RICHLAND, WA--(Marketwired - Jun 23, 2015) - IsoRay, Inc. (NYSE MKT: ISR) has retained Wilson Sonsini Goodrich & Rosati to defend the Company and certain officers named in several lawsuits filed against it related to a press release on May 20, 2015.

The lawsuits relate to a May 20 Company press release, regarding a May 19 online publication of the peer-reviewed article in the journal Brachytherapy titled "Analysis of Stereotactic Radiation vs. Wedge Resection vs. Wedge Resection Plus Cesium-131 Brachytherapy in Early-Stage Lung Cancer" by Dr. Bhupesh Parashar, et al.
