I have the opportunity to buy into the business I work for. The stock?

[Jamiee]

shares were frozen at a value 4 years ago (or about 3 times less than they are worth now). They rate is frozen for another 3 years. I run the major division of the company and the day to day operations and have grown it substantially. The company holds two divisions, the division I am responsible for (which has grown in value 3x) and a second division I am not responsible for (break even profit, if lucky). I now own about 10% and there is a total of 40% more percent available to 4 of us who an buy on a first come, first serve basis. I am slated to own the most as I am paid a bonus based on performance and my performance has been strong, where others have been weak. Thus, allowing me the money to buy into the company. I did not receive dividends the first 2 years, but rather just enough of a dividend to pay the percentage of the taxes I would own on my portion of the business. This last year I was offered 6% dividend against that year's investment. My question is first: if the stock prices are frozen and I am not getting dividends, why would I buy now but rather hold onto the cash and let it generate additional income and buy all right before the cut off date is lifted? (The price is frozen for 7 years at the fixed stock value rate). Second, the company is extremely profitable and continues to be so and the money is not being reinvested for growth. We do not have a board, so there is one majority shareholder who determines the dividends, what should I expect as shareholder? Many more questions - but let's start with these.
