KnowledgeWorks is integrated with LispWorks so you cannot exit from KnowledgeWorks independently. You can close individual KnowledgeWorks windows by Window > Close Window. You can exit LispWorks by choosing LispWorks > Quit LispWorks. If you have any unsaved edited files you will be asked whether you wish to save them. There will be a final confirmation before KnowledgeWorks quits.
