That would probably be illegal, though I am sure these things go on and are not discovered.
In any case, since your post, PDN have extended the bid thus telegraphed the fact that they want (or are resigned to getting?) the whole company and proceeding with compulsory acquisition. They are at 87% as of 19th October and are virtually certain to reach 90% so there is a low risk arbitrage for those who want it. NGM at 16 cents => PDN at 382.4 under the terms of the take over (as compared with PDN at just over 400 at the moment). -- My advice is free and worth every cent.
