JVP agreement doesn't require practitioners remain at the practice. Practitioners could leave the practice and still retain profit share, obviously in most cases as the practice principal this would be like shooting yourself in the foot in respect to the profit share (if they are actually benefitting from the profit share anyway).
There is a substantial risk that dissatisfied JVP's exercise their buy-out clause, which would require SIL to find a buyer for the JVP within 12 months or buy-out the JVP themselves. This could be an issue in aprox. 12 months time. Certainly enough problems right now with cash flow issues.
