The prosecutor must give written notice at least 7 days before the Omnibus Hearing of intent to seek an aggravated sentence. Notice may be given later if permitted by the court on good cause and on conditions that will not unfairly prejudice the defendant. The notice must include the grounds or statutes relied upon and a summary statement of the factual basis supporting the aggravated sentence.
