You are getting this error because there is no extent large enough in your target tablespace that will hold the INITIAL extent. You could either add more space to your tablespace or pre-create your table and import with ignore=y.

To pre-create your table, add the indexfile option to the exp command:
exp system/yourpw@yourdb file=yourexpfile.dmp indexfile=yourdb.sql tables=...

Then, in yourdb.sql will be a bunch of DDL that you can edit and pre-create your tables.
