(TSX:WNX)("Warnex") today announced that it has sold the assets of its Medical Laboratories division to Gamma-Dynacare Medical Laboratories ("Gamma-Dynacare"), one of Canada's largest providers of medical laboratory services, for gross proceeds of $7.5 million (the "Transaction"). Warnex also announced that, in obtaining the requisite approvals for proceeding with the Transaction, it has reached an agreement with the four holders (collectively, the "Debentureholders") of all of its outstanding debentures (collectively, the "Debentures") whereby the Debentureholders have consented to the Transaction and Warnex has agreed to use a portion of the sale proceeds generated from the Transaction to fully repay and settle the Debentures of three of the Debentureholders and to repay a substantial portion of the Debentures held by the remaining Debentureholder.

The Transaction

Pursuant to the Transaction by which Gamma-Dynacare has acquired Warnex's Medical Laboratories division, Gamma-Dynacare has also assumed certain liabilities of the division and will provide employment to the 25 employees specific to the division. Warnex may also receive up to an additional $2.6 million in consideration in the form of an earn-out based upon the financial performance of the Medical Laboratories division in the 12 months following the closing of the Transaction. The terms of the Transaction also provide that Warnex will lease to Gamma-Dynacare certain dedicated laboratory and office space for a period of three years and will assist in the smooth transition of the operations to Gamma-Dynacare in order to provide uninterrupted service to customers.

Repayment of Debentureholders

With respect to the agreement on the repayment of the Debentures, three Debentureholders were owed approximately US$3,135,481, US$1,091,097 and US$363,699, respectively, in principal and interest on their 18% convertible Debentures due January 31, 2012 (the "January 2012 Debentures"). Each of such three Debentureholders agreed to accept a one-time payment from Warnex equal to 91% of the amount of principal and interest owed on its January 2012 Debenture in full payment and settlement of such Debenture, which payments were collectively equal to approximately US$4,177,152. The fourth Debentureholder, Persistence Capital Partners LP ("PCP"), was owed prior to the closing of the Transaction approximately CDN$2,140,815 on the January 2012 Debenture it holds and approximately CDN$602,960 on the 18% convertible Debenture due February 29, 2012 (the "February 2012 Debenture") it holds. PCP agreed to accept a one-time payment from Warnex of CDN$1,166,104, which was equal to approximately 42.5% of the collective amount of principal and interest owed on its January 2012 Debenture and February 2012 Debenture, with the 57.5% balance owing on such Debentures remaining outstanding.

Warnex intends to use the remaining proceeds from the Transaction for working capital purposes.

"Warnex has been working diligently over the past few months to improve its balance sheet and position the Company for the future. The sale of the Medical Laboratories division and the agreement with the debentureholders are key steps in this process, and over the coming months we will continue to focus our efforts on positioning the company for future success and increasing shareholder value," said Michael Singer, Chairman of the Executive Committee of the Board of Directors.
