WEX Pharmaceuticals Inc.: Option Amendments Approved

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 10, 2007) -

NOT FOR DISSEMINATION IN THE UNITED STATES

WEX Pharmaceuticals Inc. ("WEX" or the "Company") (TSX:WXI) today announced that the Toronto Stock Exchange (the "TSX") has conditionally approved certain amendments to the exercise prices and terms of 1,877,999 stock options (the "Prior Options") that were previously granted to certain directors, employees and consultants who are non-insiders of the Company. These amendments to the Prior Options are intended to coincide with the Company's planned rights offering to its existing shareholders (the "Rights Offering") and will only be effective if the Rights Offering proceeds.

If the Rights Offering proceeds, documents regarding the Rights Offering should be mailed to shareholders in the first quarter of 2007, with the rights expected to be exercisable for a period which is not less than 21 days (the "Rights Offering Period"). WEX intends to grant shareholders of record as of the relevant date one right for each common share held. Five rights would entitle the holder thereof to acquire one common share at a subscription price per common share equal to the volume weighted average trading price of the Company's shares on the Toronto Stock Exchange for the five trading days immediately preceding the date the Rights Offering is launched, less a discount of 20% (the "Rights Exercise Price").

All of the Prior Options that were set to expire prior to the end of the Rights Offering Period will be extended so that they expire on the earlier of June 29, 2007 and the last day of the Rights Offering Period. Those Prior Options that expire after that date are not being extended.

During the Rights Offering Period, the exercise prices of the Prior Options will be temporarily reduced to the greater of the Rights Exercise Price and $0.195, which was the market price (calculated in accordance with the Company's Stock Option Plan) of the Company's common shares on December 19, 2006, the day prior to the amendments. After the Rights Offering Period, the exercise prices of those Prior Options that remain outstanding will revert back to their original exercise prices until their expiry.

The amendments to the Prior Options are intended to increase the likelihood that the Prior Options will be exercised, potentially resulting in additional capital being raised by the Company. For additional information regarding the amendments, please contact Helen Chai, Associate Manager, Corporate Communications, at 604-676-7910.

Due to regulatory concerns, WEX will not proceed with the warrant amendments described in the Company's Management Proxy Circular for its Annual and Special Meeting of Shareholders that took place on September 29, 2006.
