2. (2) a legislative or executive agent registered pursuant to section forty-one of chapter three, or a lobbying group or organization registered pursuant to section forty-four of chapter three, or an officer, employee, or agent of such legislative or executive agent or lobbying group or organization acting in its behalf; or
3. (3) any person charged with the responsibility of delivering individual contributions from a group of officers or employees or a combination thereof of a corporation who have pooled such contributions.

(d) Nothing in this section shall prohibit:

1. (1) a bona fide joint fund-raising effort conducted solely for the purpose of sponsorship of a fund-raising reception, dinner, or other event, in accordance with the rules prescribed by the director by 2 or more state or local committees of a political party acting on their own behalf; or
