Leased Employees w/401k

[DP]

We have a medical practice that was bought out by the hospital. The group of doctors at the practice have incorporated and now lease the NHCE's from the hospital. The hospital has a 401k plan with an employer match which the NHCE's participate in. There is no employer discretionary contribution from the hospital.

The doctors have set up their own 401k plan. There is no match, but they do have an employer discretionary contribution. Would the doctors have to make a discretionary contribution for all of the eligible leased employees?

Does the doctors 401k stand on its own for testing? I need help in understanding how all this works (in plain English, please).
