If this was me, I would tell him to take her 10% out of his 50% because they will be acting as a unit and constantly overriding you if they have majority control of the company. It's really bad news. If he doesn't want to do that then tell him to pound sand, share structure is not changing and be prepared for this enterprise to eat it before it even takes off (It is generally better for things like this to be stillborn rather than die five years down the line when you are older and less able to start over/take risks because you are further along in your personal life cycle).
