Query: Lots about taxes, little about other regulations

I bought this book and was hoping to see a clear description of SEC Rule 144 and other rules restricting sale of nonregistered stock. In the 80s Rule 144 meant you had to exercise your options and then hold them two years before you could sell them to anyone except the company that issued them. This is different now, but I am not clear on how. I would also have liked to see something on insider trading restrictions and lock-up agreements (which also restrict sale). This book does not tell the stock option novice what he/she needs to know at all about what the best approach is. In my experience I have made the most when I exercised as early as possible and then held the stock for 5+ years, but if that's the right strategy, what do we need options for?
