Can bad board voting put a condo association in a lawsuit?

I'm on my condo board in Colorado. The board will vote on a 7 year contract even though our bylaws say a contract can only be 5 years and the attorney has made this clear. As a board member who will vote no, am I personally liable if we are sued? Should I resign from the board to avoid liablity? I would consider this gross neglegence if it passes - would the D&O insurance protect me if I vote no?
