Ann: Appendix 3B - Conversion of Convertible Notes, page-5

They have convertable notes and have to cough up interest until they are converted to shares or paid in full.

These ones come from 2012. So that means someone lent them 750k back in 2012 for 5 years. Time has run out so they decided to convert to shares rather than being paid in full. Therefore that means whoever has those shares thinks they are worth more than 3c so that is the good part, the sad part is if they don't want to invest in NAG then theres 21 million shares waiting to be sold hopefully above 3c so they make more money on top of the interest they've earned.
