        (g)  to restate the articles of incorporation as currently
             amended.  (Section 10.15)

NOTE 4: All amendments not adopted under Section 10.10 or Section 10.15 require
        (1) that the board of directors adopt a resolution setting forth the
        proposed amendment and (2) that the shareholders approve the amendment.

        Shareholder approval may be (1) by vote at a shareholders' meeting
        (either annual or special) or (2) by consent, in writing, without a
        meeting.

        To be adopted, the amendment must receive the affirmative vote or
        consent of the holders of at least 2/3 of the outstanding shares
        entitled to vote on the amendment (but if class voting applies, then
        also at least a 2/3 vote within each class is required).

        The articles of incorporation may supersede the 2/3 vote requirement by
        specifying any smaller or larger vote requirement not less than a
        majority of the outstanding shares entitled to vote and not less than a
        majority within each class when class voting applies. (Section 10.20)

NOTE 5: When shareholder approval is by consent, all shareholders must be given
        notice of the proposed amendment at least 5 days before the consent is
        signed. If the amendment is adopted, shareholders who have not signed
        the consent must be promptly notified of the passage of the amendment.
