Give feedback. Explain to your co-worker what you're seeing and experiencing. Describe the impact of his behavior on you and provide suggestions for how he might change.
Focus on work, not the person. You need to get the work done despite your peer's style, so don't waste time wishing he would change. Concentrate on completing the work instead.
Ask for commitment. At the end of a meeting ask everyone (not just the troublemaker) to reiterate what they are going to do and by when. Sometimes peer pressure can keep even the most passive-aggressive person on task.
