Warnex Provides an Update on its Operations

LAVAL, QUEBEC--(Marketwire -04/04/12)- Warnex Inc. (TSX: WNX.TO - News) ("Warnex") wishes to provide the following update regarding its operations.

Financial Situation

Warnex announces that it has reached an agreement with Persistence Capital Partners LP ("PCP"), the holder of its outstanding debentures (the "Debentures"), regarding the conversion of a portion of the Debentures and the repayment of the remaining balance. The conversion of CDN$725,000 in principal amount of the Debentures into an aggregate of 46,178,344 common shares of Warnex ("Common Shares") pursuant to a notice of conversion received by Warnex on March 16, 2012, will be effected on or about April 5, 2012. As a result, PCP will own approximately 51.56% of the outstanding Common Shares of Warnex.

Furthermore, PCP has agreed to allow Warnex until April 13, 2012 to repay the remaining balance of approximately $959,420 owing under the Debentures, with the expectation that by such time, Warnex will be able to put into place an operating line of credit with a financial institution for up to CDN$2,000,000 in order to provide Warnex with the funds necessary to repay such outstanding balance and to support future working capital requirements. While Warnex is well advanced towards putting this credit facility into place, no assurances can be given that Warnex will be successful in this regard.

Appointment of Interim Chief Executive Officer

Warnex also announces that Marc Lebel has been appointed as the Interim Chief Executive Officer of the company. Mr. Lebel is the co-founder of Anapharm, a Phase I contract research organization that employed as many as 1,200 personnel. Mr. Lebel was Executive Vice-President of Pharmanet from 2005 to 2007, following its acquisition of Anapharm. Mr. Lebel is currently a director of Acasti Pharma Inc. and Nuchem Inc. His primary role within Warnex will be to ensure the integrity of the company's operations as the Board of Directors continues its assessment of the strategic alternatives available for the company.

Exchange Listing

As a result of the new developments described above, the Toronto Stock Exchange has agreed to extend the deadline for the delisting of the Common Shares to April 16, 2012. Warnex continues to explore its various options in light of this scheduled delisting.
