     Pursuant to the provisions of Article 4.04 of the Texas Business

     The following amendment to the Articles of Incorporation was adopted by the

     "A director of the Corporation shall not be liable to the Corporation or
     its shareholders for monetary damages for any act or omission in the
     director's capacity as a director, except that this Article Nine does not
     eliminate or limit the liability of a director for:

        (a) a breach of a director's duty of loyalty to the Corporation or its
            shareholders;

        (b) an act or omission not in good faith or that involves intentional
            misconduct or a knowing violation of the law;

        (c) a transaction for which a director received an improper benefit,
            whether or not the benefit resulted from an action taken within the
            scope of a director's office;

        (d) an act or omission for which the liability of a director is
            expressly provided for by statute; or

        (e) an act related to the unlawful stock purchase or payment of a
            dividend.

     If the Texas Miscellaneous Corporation Laws Act or the Texas Business
     Corporation Act, as amended, further eliminates or limits the personal
     liability of directors, then the liability of a director of the corporation
     shall be eliminated or limited to the fullest extent permitted by such
     statute, as so amended. Any repeal or modification of the foregoing
     provisions of this Article Nine shall not adversely affect any right of
