                    INFORMATION TO BE INCLUDED IN THE REPORT

ITEM 1.01  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT

On May 27, 2008, BOK Financial Corporation (the "Company") entered into a 10b5-1
Repurchase  Plan with BOSC,  Inc., a registered  broker/dealer  and wholly owned
subsidiary,  to purchase  Company common stock in compliance with Rule 10b5-1 of
the Securities  Exchange Act of 1934, as amended (the "10b5-1 Plan"). The 10b5-1
Plan will allow the Company's Rule 10b-18 share  repurchase  program to continue
during  periods when the Company would  normally not be active in the market due
to its internal trading black out periods and may be aware of material nonpublic
information.

On April 26, 2005,  the Company's  board of directors  authorized the Company to
repurchase  up to two million  shares of the  Company's  common  stock under the
repurchase  program.  As of March 31, 2008, the Company had repurchased  709,073
shares under the repurchase program.

Pursuant to the terms of the 10b5-1 Plan,  BOSC,  Inc., as agent for the Company
and through a mirrored  execution  agreement  with  Pershing  LLC, will purchase
varying percentages of the maximum daily volume allowable under Rule 10b-18 when
the Company is trading at various price ranges.  Any purchases  under the 10b5-1
Plan will be disclosed publicly through  appropriate filings with the Securities
and Exchange Commission.

The  description  of the Plan in this Item 1.01 is  qualified in its entirety by
reference  to the text of the plan,  a copy of which is filed as Exhibit 10.1 to
this Form 8-K and incorporated herein by reference.

          with  the  Purchases  of Stock in the  open  market  pursuant  to this
          Repurchase  Plan.  The Issuer agrees not to take any action that would

          foregoing;

     (5)  The public announcement of a tender or exchange offer for the Stock or
          of a merger,  acquisition,  recapitalization or other similar business
          combination  as a result of which the Stock would be exchanged  for or
          converted into cash,  securities or other property; or

     (6)  The failure of the issuer to comply with Section 2 hereof.

     (b)  Sections 2 and 12 of the Repurchase Plan shall survive any termination
          hereof. In addition, the Issuer's obligation under Section 2 hereof in
          respect  of any  shares of Stock  purchased  prior to any  termination
          thereof shall survive any termination hereof.

4.   The Issuer  understands  that BOSC may not be able to effect a Purchase due
     to market  disruption or legal,  regulatory or contractual  restrictions or
     internal policy applicable to BOSC or otherwise.  If any Purchase cannot be
     executed  as  required  by Section 1 due to a market  disruption,  a legal,
     regulatory or contractual restriction or internal policy applicable to BOSC
     or any other  event,  such  Purchase  shall be  cancelled  and shall not be

     to the Issuer or any of its subsidiaries or any of its or their property or
     assets.
