The Warrants were issued in relation to a non-brokered private placement of units comprised of one common share and a common share purchase warrant, completed on August 21, 2014. Each Warrant currently entitles the holder to purchase one common share of Microbix at a price of $0.55 until August 21, 2019. Microbix has applied to the TSX to amend the exercise price of the Warrants to $0.32, and to extend their term to August 21, 2021. The five day volume-weighted average price of Microbix's share is $0.28 as at the date of TSX application.

The Warrants were acquired by Mr. Joseph D. Renner in relation to his participation in the 2014 private placement. Mr. Renner has been an independent member of Microbix's board of directors since 2003 and, like Microbix's other independent directors, has invested significant time in the course of executing his responsibilities: Notably, while he has participated in many directors' meetings over the past 30 months, he has taken no cash or option compensation in that interval.

"The warrant repricing application announced today is intended to acknowledge Mr. Renner's services to Microbix without increasing our fully-diluted share count," said William J. Gastle, Executive Chairman. "We need to encourage the active participation of the board members who can help us accelerate the growth of Microbix while remaining responsible to our shareholders. We believe this application serves both those imperatives."

Mr. Renner will not be permitted to exercise the Warrants under the amended terms unless and until disinterested shareholder approval is obtained, along with TSX approval. Disinterested shareholder approval will be sought at the next annual meeting of shareholders, anticipated to be held in early 2018.

The Toronto Stock Exchange (TSX) does not accept responsibility for the adequacy or accuracy of this release.
