OTTAWA, ONTARIO, April 12, 2013 - Avivagen Inc. (VIV.V), a wellness company committed to developing and delivering products that support and improve the health and quality of life for animals and the people who care for them, is pleased to announce its applications for the conversion of liabilities into common shares and to extend the term of certain common share purchase warrants. These actions are intended to strengthen the company's financial position and are subject to regulatory approval.

Conversion of Liabilities

Avivagen has reached agreements for the conversion of $721,668 of payables into common shares, which will result in the issuance of 10,612,757 common shares at a price of $0.068 per share. On approval, this action will reduce Avivagen's balance sheet liabilities and increase its shareholders' equity by that same dollar amount.

Chris Boland, CFO of Avivagen commented "This action enhances the financial strength of our company and should improve our ability to achieve stated objectives. We appreciate the support of our business partners in undertaking these conversions."

Extension of Common Share Purchase Warrants

Avivagen has applied to extend the expiry date of 3,975,000 outstanding common share purchase warrants. The warrants were issued by Avivagen in April and May of 2011 by way of private placement and currently have expiry dates of April 29, 2013 and May 27, 2013. Each warrant entitles the holder to acquire one common share of Avivagen at a price of $0.10. The expiry date of the warrants is proposed to be extended to June 30, 2013. All other terms and conditions of the warrants will remain unchanged.

Cameron Groome, CEO and President noted "Financial sustainability and supportive shareholders are important to our company, helping us develop and maintain all types of business relationships. Increasing Avivagen`s equity base and reducing its liabilities assists with the supply, distribution and marketing alliances needed to realize our many animal health opportunities."

Regulatory Approvals

The conversions and extensions referenced above are effective April 11, 2013 subject to the necessary TSX Venture Exchange and Ontario Securities Commission approvals.
