Aircraft cleared for takeoff on runway 19R. Aircraft lifted off approximately 4000 ft from approach end of runway. Immediately after lift-off; tower control announced; 'stay low;' followed by 'stay low; aircraft departing runway 25R.' PIC in left seat looked left to observe a regional jet at 10 O'clock position; just lifting off runway 25R. PIC leveled aircraft at approximately 300 ft; while aircraft departing runway 25R continued to climb. At leveloff; egpws announced 'sink rate.' PIC continued to monitor conflict aircraft's position. As our aircraft crossed extended centerline of runway 25R; conflict aircraft was at 9 O'clock position; approximately 1 mi; and above our altitude.
