Ahjay here are the two offerings. Notice Viralytics placement has no Warrants or  convertable note.  No seat on the board.  No Chance at giving over controlling interest of the company to a Hedge fund if warrants are taken up.  Yes there was a bigger discount given to VLA shares and that to me was the only difference.
VLA
The Placement and the Entitlement Offer price of $0.28 represents a 12.5% discount to the weighted average closing price for the fifteen trading days to 24 January 2014 (being the last trading day before the capital raising was announced by the company).
The Placement comprises two Tranches.

1. Tranche 1 is a $6.1 million placement to professional and sophisticated investors using Viralytics' existing placement capacity under the ASX Listing Rules (First Tranche Placement);
2. Tranche 2 is a $16.9 million placement to professional and sophisticated investors and is subject to shareholder approval (Second Tranche Placement). A shareholder meeting is expected to be held on or around 6 March 2014.
3. Under the Entitlement Offer, eligible shareholders will be able to subscribe for 1 new ordinary share in Viralytics for every 6 existing shares held at 7.00 pm (AEDT) on Friday, 7 February 2014 (Record Date) at the offer price (Entitlements).  

PRR
