I observed a Mode C intruder code XXXX enter my airspace from the Shoshone MOA.  The code was at FL222 the MOAs were active up to FL230.  The code spilled out approximately 3 miles into my airspace then I called Joshua (the controlling agency) and asked what the aircraft was doing.  They responded that they did not know; but would find out.  In the meantime; I was also working Aircraft Y climbing out of LAS and was out of approximately FL200 for FL380.  I stopped Aircraft Y's climb at FL210 until I observed the code return to the MOA.  I observed Aircraft X about 10 miles outside the MOA before it turned back.Joshua should have called me to point out the aircraft.  It is somewhat disconcerting to have an active MOA only 4 miles away from the LAS departures especially when spill outs are possible.
ZLA Controller describes scenario where a spill out happens close to a busy airport's departure path.
