Upon a showing of good cause, the party sponsoring the expert witness may be permitted to amplify the written direct testimony during the hearing.
(c) Cross-examination and redirect examination of expert witness. Cross-examination, redirect examination, and re-cross-examination of an expert witness shall proceed in due course based upon the written testimony and any amplifying oral testimony.
(d) Failure to file or exchange written testimony.
