Well that is why making up these "quasi pretendo companies" is not a good idea.  If it was actually a partnership then yes all partners are equally and fully liable.  Of course that would require a partnership agreement and partnerships don't have shares, stock, or shareholders.   It is almost like Nefaro took the worst aspects of a partnership, sole proprietorship, limited liability company, and corporation and turned it into some franken company.  

Maybe that is the lesson in all this.  Forming a real discrete (i.e. seperate from the owners) legal entity is trivial these days and cost a norminal amount of money.  It then lets us answer questions like the above and prevents any ambiguity.  I mean how many "shareholders" realized that under a partnership they have unlimited personal liability (i.e. you can lose everything you own, your house, your car, all your assets, the money from your bank account, and even the clothes from your closets).
