(b) fabricate evidence, counsel or assist a witness to testify falsely, or offer an inducement to a witness, except a lawyer may pay a witness reasonable expenses incurred by the witness in attending or testifying at proceedings; a reasonable, noncontingent fee for professional services of an expert witness; and reasonable compensation to reimburse a witness for the loss of compensation incurred by reason of preparing for, attending, or testifying at proceedings;
