One of my concerns is that Prime will gain majority ownership. The will buy-out the rest of the shareholders for a knock-down price. I got caught on Ecorp (a few years ago - owned ebay and a few other top growth busineesses). Consolidated Press Holding (CPH) post dot-com bust starting pick up the stock at bargain basement prices.

The got a majority holding (as PRT are now) and made an offer to minority shareholders, quite a substantial amount had sh1t themselves with decent paper losses on their hands. They took it (even though it was relatively p1ss poor) it was above the then market price by 20% or so, and CPH compulsory acquired my shares. Albeit at a knock down price, and even though I didn't want to sell them. A similar situation here concerns me, although admittedly PRT hold relatively a much smaller stake.
