An attorney may serve as a director, officer or member of a legal services organization, apart from the law firm in which the attorney practices, notwithstanding that the organization serves persons having interests adverse to a client of the attorney. The attorney shall not knowingly participate in a decision or action of the organization:

(a) if participating in the decision would be incompatible with the attorney's obligations to a client under Rule 19-301.7 (1.7); or

(b) where the decision could have a material adverse effect on the representation of a client of the organization whose interests are adverse to a client of the attorney.
