- if the 'entry' is 3 - you don't want to consider it?

pretty easy in two steps ...
step 1 to count ... occurrences for file2
something like ( adjust for Your environment )
Code:
 000004 //s       EXEC PGM=SORT
 000005 //SYSOUT    DD SYSOUT=*
 000006 //SYSPRINT  DD SYSOUT=*
 000007 //SORTIN    DD *
 000008 AAAA
 000009 BBBB
 000010 BBBB
 000011 CCCC
 000012 CCCC
 000013 CCCC
 000014 EEEE
 000015 EEEE
 000016 FFFF
 000017 FFFF
 000018 FFFF
 000019 FFFF
 000020 //SORTOUT   DD SYSOUT=*
 000021 //SYSIN     DD *
 000022   SORT  FIELDS(01,4,CH,A)
 000023   INREC OVERLAY=(11:C'0001')
 000024   SUM   FIELDS(11,4,ZD)
 000025   OUTFIL  OMIT=(11,4,ZD,NE,2)

step 2 use join key to match with file 1

Well, the two steps can be done in one, using JNFnCNTL (if DFSORT, or SyncSort with support for JNFnCNTL).

Subject to a full description of the problem, it is straightforward with what enrico has suggested, just "compressed into one step" if possible, else as two.
