PID Provider dtrace script

I'm just starting to mess about with dtrace on Solaris. How do I configure a probe in a PID provider dtrace script to trigger when the process being traced exits? I've tried pid$1:::exit where $1 is the PID but I get 'exit' is an invalid probe name

NAME

       lockstat - DTrace kernel lock instrumentation provider

DESCRIPTION

       The  lockstat  driver is a DTrace dynamic tracing provider that performs dynamic instrumentation for locking primitives in the Solaris ker-
       nel.

       The lockstat provider makes probes available that you can use to discern lock contention statistics, or to understand virtually any  aspect
       of locking behavior inside the operating system kernel. The lockstat(1M) command is implemented as a DTrace consumer that uses the lockstat
       provider to gather raw data.

       The lockstat driver is not a public interface and you access the instrumentation offered by this provider  through  DTrace.  Refer  to  the
       Solaris	Dynamic  Tracing  Guide  for  a  description  of the public documented interfaces available for the DTrace facility and the probes
       offered by the lockstat provider.
