Item 5.  Other Events.

Amendments to Stock Option Plan

On April 26, 2001, the Board of Directors of BancFirst Corporation (the
"Company") approved  amendments to the BancFirst Corporation Stock Option Plan
(the "Plan").  The amendments increase the number of shares authorized under the
Plan from 850,000 to 1,100,000 and extend the term of the Plan to December 31,
2011.  The amendments were approved by the shareholders of the Company at the
Annual Shareholders' Meeting on May 24, 2001.

Amendments to BancFirst Corporation Employee Stock Ownership and Thrift Plan

On May 24, 2001, the Board of Directors of the Company approved amendments to
the BancFirst Corporation Employee Stock Ownership and Thrift Plan. The
amendments changed the eligibility requirements from age 18 and 1000 hours of
service in the 12 consecutive month period following commencement of employment,
in age 21 and 500 hours of service in the six consecutive month period following
commencement of employment.

Increase to Stock Repurchase Program

The Board of Directors approved an increase of 277,916 shares for the Company's
Stock Repurchase Program in its meeting on May 24, 2001.  The Program was
originally adopted in November 1999 for 300,000 shares.  This increase raises
the shares remaining to be repurchased under the plan back to the original level
of 300,000 shares.  The Program will remain in effect until the 300,000 shares
are repurchased, which may be over as much as a two to three year period.  The
stock repurchases may be funded from existing funds, dividends from the
Company's subsidiaries, or from borrowings.
