Narrative:
On approach to lex, we were given a vector to a visual approach for runway 22. I had previously heard an aircraft completing VFR practice ILS approachs. He then requested to proceed back to their home airport. I looked on my mfd and noticed his path would cross ours at some point. Traffic was called out 9 O'clock position, 1000 ft low. We had that traffic on TCASII. We saw another target that was not called out on TCASII. It was 10 O'clock and 500 ft low. I saw the traffic as we got a TA. I soon lost the traffic and we got an RA to 'climb, climb now.' I disconnected the autoplt, increased pitch and added power. We were soon clear of conflict. We asked ATC about the traffic and he said he forgot. Better callouts would help prevent.

Title: POTENTIAL CONFLICT BTWN A DO-328 AND A C172 TRAINING FLT CLBING NEAR 6000 FT, JUST ABOVE THE CLASS C AIRSPACE OF LEX, KY.
Narrative: ON APCH TO LEX, WE WERE GIVEN A VECTOR TO A VISUAL APCH FOR RWY 22. I HAD PREVIOUSLY HEARD AN ACFT COMPLETING VFR PRACTICE ILS APCHS. HE THEN REQUESTED TO PROCEED BACK TO THEIR HOME ARPT. I LOOKED ON MY MFD AND NOTICED HIS PATH WOULD CROSS OURS AT SOME POINT. TFC WAS CALLED OUT 9 O'CLOCK POS, 1000 FT LOW. WE HAD THAT TFC ON TCASII. WE SAW ANOTHER TARGET THAT WAS NOT CALLED OUT ON TCASII. IT WAS 10 O'CLOCK AND 500 FT LOW. I SAW THE TFC AS WE GOT A TA. I SOON LOST THE TFC AND WE GOT AN RA TO 'CLB, CLB NOW.' I DISCONNECTED THE AUTOPLT, INCREASED PITCH AND ADDED PWR. WE WERE SOON CLR OF CONFLICT. WE ASKED ATC ABOUT THE TFC AND HE SAID HE FORGOT. BETTER CALLOUTS WOULD HELP PREVENT.
