Silent Partner vs. Buyout

One of our business partners is resigning as a manager of our LLC, so she becomes a silent partner. Is there any harm to having a silent partner or is it better to negotiate a buyout? She wants to be a supporter of the farm, but her equity is so small that she doesn’t have the rights to sway the business in one direction or the other.

Also, do you all have examples of any buy-sell agreements for withdrawing members? Thank you!
