How much will it cost me to take my money out of my 401K?

I will be laid off at the end of December and I have been contribuiting to my 401K at my job for the last 2 1/2 years. What is the penalty for taking my money and not enrolling it into a new IRA or other account? Please note that all the money that is in my 401K is money that I have contributed alone no additional monies were dispursed from my employer.
