From your perspective I think the most powerful thing you can do is let them know you're willing to walk away. I don't know what to tell you to ask for in terms of price but I do know $10k is the starting point of the negotiation and is probably not their best offer by any means. Don't automatically assume you have to accept their terms and negotiate on price. You can ask for anything you want. You don't get what you don't ask for. If it's a publicly traded company why not ask for stock? A stock deal might be more valuable than a cash deal. Something to consider.
