A military F16 departed restr airspace requesting IFR clearance. The data controller coordinated for higher altitude and was given a pointout on a C650 at 12000 ft. The F16 was cleared to 11000 ft, then issued a higher altitude when the C650 was observed descending in close proximity.

Narrative:
Fgt X departed R3403 on a west heading looking for his IFR clearance to mtc. I called indy approach to point out fgt X climbing. They accepted the pointout. Next I called shb sector to coordinate fgt X climbing to the altitude of their choice and on the heading of their choice. They requested a 310 degree heading and climbing to FL230 with respect to cga Y who was at 12000 ft, eastbound. I then coordinated this information to the radar man who assigned fgt X 11000 ft and heading 310 degrees. A min or so later we both noticed cga Y descending and the radar man turned fgt X to a 270 degree heading and told him to expedite to FL230. A few seconds later he asked fgt X his altitude. He (fgt X) replied 'leaving 160.' he was then cleared on course.

Title: A MIL F16 DEPARTED RESTR AIRSPACE REQUESTING IFR CLRNC. THE DATA CTLR COORDINATED FOR HIGHER ALT AND WAS GIVEN A POINTOUT ON A C650 AT 12000 FT. THE F16 WAS CLRED TO 11000 FT, THEN ISSUED A HIGHER ALT WHEN THE C650 WAS OBSERVED DSNDING IN CLOSE PROX.
Narrative: FGT X DEPARTED R3403 ON A W HEADING LOOKING FOR HIS IFR CLRNC TO MTC. I CALLED INDY APCH TO POINT OUT FGT X CLBING. THEY ACCEPTED THE POINTOUT. NEXT I CALLED SHB SECTOR TO COORDINATE FGT X CLBING TO THE ALT OF THEIR CHOICE AND ON THE HEADING OF THEIR CHOICE. THEY REQUESTED A 310 DEG HDG AND CLBING TO FL230 WITH RESPECT TO CGA Y WHO WAS AT 12000 FT, EBOUND. I THEN COORDINATED THIS INFO TO THE RADAR MAN WHO ASSIGNED FGT X 11000 FT AND HEADING 310 DEGS. A MIN OR SO LATER WE BOTH NOTICED CGA Y DSNDING AND THE RADAR MAN TURNED FGT X TO A 270 DEG HDG AND TOLD HIM TO EXPEDITE TO FL230. A FEW SECONDS LATER HE ASKED FGT X HIS ALT. HE (FGT X) REPLIED 'LEAVING 160.' HE WAS THEN CLRED ON COURSE.
