Operating Agreement Amendment -- Adding member

[Rick L.]

I've reach the point where my profession career is becoming too busy to be as hand on managing my rental properties as I once did. I'd like my father to begin dealing with day to day operations fielding, -ie, maintenance calls, running to banks/dealing with lenders, showing vacant units, etc, etc.  

I need to amend my LLC's operating agreement adding him as some sort of member. Does anyone have any "example" of their operating agreement they could provide? Perhaps a multiple member operating agreement?
