Agreed. The Bay Area lawyer I've used for a dozen years is Adam Slote: http://slotelaw.com/

I strongly recommend that you talk to someone like him. An experienced lawyer will be able to put this in perspective for you in short order: industry norms and expectations, legal options, negotiating tactics.

This could go all sorts of ways. On one memorable occasion, this lawyer wrote a short letter and got me $20k in wages owed. On others he's advised me to just walk away.

I'd also suggest you consider cash instead of equity, especially payment for expenses. You may prefer a longer runway (or a month recovering on a Mexican beach) instead of more lottery tickets.
