You can find it in "contacts.ezpkg" in: http://packages.ez.no/ezpublish/3.8/
Its a package used in old versions of eZ Publish, shoudl be possible to import in a new site using Setup -> Packages -> Import (in admin). If not, you can open the file in any zip program ( 7zip is a free archiver that handles it, I think WinRar and WinZip does open it as well as it's just a renamed .tar file ), and open file ezcontentclass/class-company.xml in any proper xml/text reader (Notepad++ or even Firefox / IE).
