At what point will you sell your shares? During a merger, do you want to sell prior to or after the merger?

I own 90,000 shares of stock in a bio fuel (ethanol & bio diesel) and commercial development company. I have always been interested in a good stock investment due to the highest rate of return on your money. This company is very small. I am sure it will grow over the years. The President & CEO is a personal friend of mine. Question (2). Since I own so many shares, does this qualify me to sit on the Board of Directors?
