ITEM 5.03  Amendments to Articles of Incorporation or Bylaws

         On October 30, 2007, the BOK Financial Corporation ("BOKF") board of
directors approved an amendment to the BOKF bylaws to allow for the election of
directors in uncontested elections by a majority vote of those shareholders
voting. Previously, the bylaws provided for the election of directors by
plurality vote in all cases. Election of directors by a plurality vote will
continue to apply for contested elections.

         The board also approved amendments to the BOKF bylaws to provide for
uncertificated shares, thus permitting book-entry ownership, as required by Rule
3450(l) of the Nasdaq Stock Market, LLC.

          Finally, the board approved certain administrative changes to update
the bylaws including expressly providing that i) voting lists shall be made
available to shareholders at least ten calendar days prior to a shareholder
meeting, ii) the board may form committees other than an executive committee,
iii) directors may participate in meetings by electronic means, and iv) the
determination of record holders and the timeframe within which to establish
record dates is consistent with current Oklahoma state law.
