Is any compensated lobbyist exempt from registering?

Yes. Registration is waived if the lobbyist:

• limits activities to public legislative committee sessions or state agency public hearings;
• participates in an effort, at the request of an agency, to reach a consensus on possible rule making but once the agency files notice of the proposed rule, efforts to influence action are no longer exempt; or
• restricts lobbying to no more than four days or parts of four days during any three consecutive months and spends no more than $100 during the three month period for or on behalf of the state officials or employees in connection with the lobbying effort
