Pursuant to a fundamental change review, the common shares of CDG Investments ("CDGI") have re-qualified for listing.  CDG and Preo Software Inc. have completed the previously announced plan of arrangement, and the shares will resume trading on Tuesday, July 29, 2008 under the new name of Preo Software Inc. 

Under the terms of the Arrangement, each shareholder of CDG (subject to a small shareholder buy-back) will receive one (1) new share of Amalco for each share of CDG currently held after giving effect to a four for one (4:1) consolidation of the CDG common shares that was approved by the CDG shareholders on July 23, 2008 (the "CDG Consolidation"). Each shareholder of Preo will receive two (2) new shares of Amalco for each share of Preo currently held. The Arrangement has resulted in the conversion into common shares of all outstanding convertible debentures and preferred shares of Preo prior to giving effect to the merger.

With the merger now completed, CDG shareholders hold an aggregate of approximately 10,239,965 Amalco shares representing 27.3% of the Amalco shares and Preo shareholders hold an aggregate of approximately 27,338,141 Amalco shares representing 72.7% of the Amalco shares. The final number of Amalco shares issued to the former CDG shareholders will be subject to the small shareholder buy-back and fractional rounding. All Preo options now represent options of Amalco on the same basis as the Preo shares were treated under the Arrangement.

Preo will continue to trade under the symbol CDGI.  All open orders on CDGI will be purged from the book at the close of business today.  Dealers are reminded to verify orders prior to entry, taking into consideration the effect of the consolidation.
