Informal Assessment - Is there a conflict of interest?

I'm looking for feedback via an informal survey from Business Brokers/Intermediaries, Investors, Searchers / Bankers / Tax Advisors, Business Attorneys, and anyone who has experienced the M&A process up close. Do you feel that the nature of the listing agreement, whereby a commission is paid only if there is a sale, creates a possible conflict of interest? Is there a better way to structure the listing agreement to achieve the objective of the highest price and best terms? Yes, No, or Maybe. Would love to get your thoughts based on your answer -- and greatly appreciate your expertise and insights. Kindest regards and Happy Holidays!
