@EXPORT hold the symbols that are exported by default when you don't mention explicitly any symbols.

use one; # will import the symbols in @EXPORT

while @EXPORT_OK hold the symbols that can be exported on demand.

use one qw(m1 m2); # m1 and m2 should be in @EXPORT or @EXPORT_OK

Read more about it in the Exporter documentation.
