(2) reasonable compensation to a witness for the witness' loss of time in attending or testifying; or

(f) in pretrial procedure, make a frivolous discovery request or fail to make reasonably diligent effort to comply with a legally proper discovery request by an opposing party;

(g) in trial, allude to any matter that the lawyer does not reasonably believe is relevant or that will not be supported by admissible evidence, assert personal knowledge of facts in issue except when testifying as a witness, or state a personal opinion as to the justness of a cause, the credibility of a witness, the culpability of a civil litigant or the guilt or innocence of an accused;

(h) request a person other than a client to refrain from voluntarily giving relevant information to another party unless:

(1) the person is a relative or an employee or other agent of a client; and

(2) the lawyer reasonably believes that the person's interests will not be adversely affected by refraining from giving such information; or

(i) present, participate in presenting, or threaten to present criminal charges solely to obtain an advantage in a civil matter.
