how to sell bltra

Hi

Hoping some of you more experienced in these matters can shine some light on this subject for those of us who now find ourselves with these BLTRA's.

Can someone please explain firstly how many BLTRA's a shareholder has the ability to sell if they hold the following number of ordinary BLT shares.

100,000 BLT?

200,000 BLT?

500,000 BLT?

1,000,000 BLT?

I'm trying to get my head around whether I can sell BLTRA's based on the conversion ratios from the issue offer or based on actual number of BLT shares held???
