Tyler Adopts Shareholder Rights Plan

CALGARY, ALBERTA--(Marketwire - Sept. 26, 2007) - Jean Pierre Jutras, President and Chief Executive Officer of Tyler Resources Inc. (the "Corporation") (TSX VENTURE:TYS) is pleased to announce the adoption by the Board of Directors of the Corporation of a Shareholder Rights Plan to protect the Corporation's shareholders from unfair, abusive or coercive take-over strategies, including the acquisition of control of the Corporation through a take-over bid that may not treat all shareholders equally or fairly. The Corporation is not aware of any specific take-over bid for the Corporation that has been made or is contemplated. The Board of Directors approved the adoption of the Plan on September 6, 2007, subject to receipt of regulatory approval which was received on September 25, 2007.

To implement the Plan, the Board of Directors of the Corporation authorized the issue of one Right in respect of each common share of the Corporation outstanding to holders of record on September 25, 2007, as well as one Right in respect of each common share issued after the record date. Initially, the Rights will attach to and trade with the common shares and be represented by certificates representing common shares.

The Plan is similar to shareholder rights plans adopted by a number of other Canadian companies. The Plan is not intended to block take-over bids. The Plan includes "Permitted Bid" provisions which do not invoke the dilutive effects of the Plan if a take-over bid is made by way of a take-over bid circular to all shareholders that remains open for a minimum of 60 days and is accepted by not less than 50 percent of the common shares held by independent shareholders. The Plan will be invoked by an acquisition, other than pursuant to a Permitted Bid, of 20% or more of the outstanding common shares of the Corporation or the commencement of a take-over bid that is not a Permitted Bid, in which case the Rights separate from the common shares and will entitle holders (other than the acquiring person or group persons) to acquire shares of the Corporation at a 50% discount to the prevailing market price of the shares.

Although the Rights Plan is effective immediately, the Corporation intends to submit the Plan to the shareholders of the Corporation for confirmation at the Corporation's next annual general meeting of shareholders expected to be held in the first quarter of 2008. If confirmed by the shareholders at this meeting, the Plan will be effective until the annual general meeting of shareholders to be held in 2010 and, if reconfirmed by shareholders at that meeting, will continue in effect until the annual general meeting of shareholders to be held in 2012.
