The question that arises in my mind upon reading his comment is whether a "regulatory" filing is required if the placement is completed

Yes, the company would have to file the short form prospectus -- look on sedar at the filing for the notes due -- which actually mature on Dec 31, 2011 according to the final filed prospectus:

"The Notes will bear interest at the rate of 9.375% per year, payable semi-annually in arrears in equal instalments on January 15 and July 15 of each year, beginning July 15, 2005. The Notes will mature on December 30, 2011."

The company would not have to file if the deal fell through, except that they would have to file a copy of the PR that it fell through.

You can get a copy from Sedar -- it was filed 12/17/2004, or I put a pdf copy on hotfile and linked it to the board DD links.
