No vesting schedules, so that makes it all the more hairy from a founder leaving stand-point. At the time we started working with him he was a responsible individual who knew what he was doing. It is only recently that these issues have popped up.

Considering that you do NOT have vesting agreement and have serious troubles in communication with one of key founders -- you should consider your company dead. Try to cut losses: dissolve the corporation, distribute the funds, save your time, and start another company with the remaining founders you trust.
