Here is what I have found regarding "public to private"....
If a company is turning private, it either means someone else is buying them out,(probably behind the scene scenario here) or they've made enough gain to make themselves self-sufficient (not the case for UOIP). Either way, your stocks are safe. To address the scenarios in reverse order: if they've gained enough profit without passing them onto the shareholders, they basically have to buy back their own stock. If they're being bought out, that newfound parent (be it another company or a single person with lots of money/way too much free time) can only demonstrate its ownership by taking stock in the company. It's technically impossible to render a share completely null and void without the company going utterly bust; that share, by definition, entitles you to any success the company enjoys, especially when it's doing well enough to be made desirable by an outside force.
A good example of this is Rareware (the guys who made the Donkey Kong Country games); they were owned 60% by Nintendo. Rare bought that 60% back from Nintendo, then turned around and sold themselves 100% to Microsoft. They went from being a Second-party developer (like Retro Studios or, once upon a time, Silicon Knights), to being (briefly) a Third-party developer, to finally becoming a First-party developer!
So the worry about public to private should not "worry" any of the long here!
Just my opinion!
