Under Cornerstone, a **Key Person Clause** is typically triggered if the named key person:

- dies
- becomes disabled or incapacitated
- resigns, departs, or is removed
- or stops devoting the required substantial business time to the fund

The usual LP remedy is:

- **automatic suspension of the investment period**
- meaning **new investments pause**
- often with **ongoing portfolio management and administration continuing**
- and LPs then typically **vote to resume investing or wind down / appoint a successor**, depending on the documents
