You need to export data from 11g or 12c and import into 9iR2. For this reason, the exp utility version 9iR2 is used to extract data from 11g or 12c. There are two aspects of this problem:

1. On some Unix platforms, the exp utility either returns no errors or crashes with core dumps.

2. On Windows platforms, exp crashes with core dumps.

Both created dumps are corrupt, the imp utility crashes immediately after the export dump header is read.
