2. (2) a statement that any answer shall be signed by the respondent or his attorney, and that any affirmative defenses, including exemptions to permit requirements, will be waived unless raised in the answer; and that the failure to answer or to appear at the hearing will result in a default and a waiver of respondent's right to a hearing; and
3. (3) a statement that the respondent may appear at the hearing either in person or by counsel, and be heard concerning any disputed matter of fact or law or with respect to the nature of any proposed resolution.
