You don't convert notes at a 1:1 ratio... those 7,000,000 convertible notes were each worth a certain amount in $$$, and thus were exchanged for however many shares would equal that amount, based on closing prices on a few previous trading days... usually at a deep discount, so those few million notes were worth several hundred million shares.

Need to read up on how that works... it's pretty common, and has a major effect on share price (as we've seen here).
