UT state partnership law, winding down, partnership buyout

Partnership buyout: I am part owner of a startup Corporation. I own 10% of the company. The agreement was that we would keep track of our time and money spent for the company and it would go towards our ownership. In my case I need to provide $50K of time and/or money to be fully vested for my 10%. I have spent about $5K of my time and money and am asking to be bought out. The others only want to pay me $1K now instead of the full 5K I have put in.

What's my options? Do I have to take the $1K? - Is this your question? Add additional information
