I am trying to find an example of "Administrative Guidelines" to be used on the behalf of a 401(k) Administrative Committee. Would anybody know where I could locate an example?

Your document provider should provide as part of the document both a compliance kit and an administrative manual with all forms, if that is your question.

If you question is what does an administrative committee do, then they handle the day to day operations of the plan in accord with the administrative kit.

I am actually looking for guidelines that the committee may use when they meet. For example, should there be a secretary? What should be done with the minutes? Are there certain procedures that the committee must follow when they meet?

Roberts Rules or ORder, just like any meeting. Keep accurate, detailed minutes. You may be challenged by any participant or fiduciary on your decisions. Actually the committee is a plan fiduciary so act as if you will have your a** sued off for anything.
