In the document, you will see the following two nominations for Director:
Norman Storm (son of Walter), who was a Director at Osisko, but also COO of EurAsia Holding AG which provided funding for Osisko under Walter Storm who was Head of the Supervisory Committee at EurAsia Holding AG.
Sean Roosen, who was COO of Osisko, but also COO of EurAsia Holding.
As majority shareholder of EurAsia Holding, Walter Storm provided funding for Osisko and delegated the management duties. Osisko was his most profitable investment and it's quite reasonable to conclude that he was very actively involved in the company that provided him with several hundred million $ when it was sold.
Here's also a note from the Osisko MD&A of November 2005:
"Eurasia Holdings AG of Germany, principal shareholder of the Company, exercised an additional lot of 1,600,000 warrants at a price of $0.30 per share in October 2005, yielding gross proceeds of $480,000. Eurasia holds 17,612,500 shares of the Company, or 47.5% of issued shares, as a result of this transaction. Funds will be used for general corporate purposes and ongoing drilling on the Canadian Malartic property."
Finally, Sean Roosen stayed with Osisko Royalties after the sale of the Malartic Mine. Here's an update on his more recent activities showing that he was named "Best CEO in North America" by Mines and Money Americas and one of the Top 20 Most Influential Individuals in Global Mining.
