Narrative:

On climb out on mar/mon/03 at XA10 at 20 NM southeast of pit airport, around 8000 ft, we queried ATC about an aircraft 5-10 mi at our 4 O'clock position if that aircraft had us in sight. We heard ATC clear him to a higher altitude and to maintain visual with us. He said he had us in sight and to level off at 10000 ft instead of our original 11000 ft. We leveled off and I told the captain to descend (or don't climb). He pushed the nose of the aircraft over and then we got an RA to climb. At that moment, the other aircraft passed over us at +100 ft, according to the TCASII display. This incident was caused by the failure of the other aircraft to maintain visual conditions with us (as cleared) and leveling off at a lower altitude than assigned to accelerate to a cruise climb.
