Number of point:
If the stock is halted because of news (good news) and the halt is longer than a day, that means there is a imbalance of buys over sell that the market makers will not or can not fill. You can then expect the market to open significantly higher (we are not talking $5 0r $10!!!). If the stock price trades more than 33% above the strike price, then ina margin account this stock becomes a free exercise (no more money needs to be put up).
When a call option is exercised, the stock must be delivered to you - you are calling it. If you have it on margin, your broker could loan it immediatly.
If you sell an 'in the money put, the stock is either put to you or you get to keep the money. You can not demand a 'put'. Hope this helps.
