               BANCFIRST CORPORATION REPORTS THIRD QUARTER RESULTS

    OKLAHOMA CITY, Oct. 19 /PRNewswire-FirstCall/ -- BancFirst Corporation
(Nasdaq: BANF) reported net income for the third quarter of 2006 of $12.7
million or $0.79 diluted earnings per share. This is a $3.5 million increase
over the third quarter a year ago of $9.2 million or $0.58 diluted earnings per
share. Net income for the first nine months of 2006 was $35.8 million or $2.23
diluted earnings per share versus $31.3 million, or $1.96 diluted earnings per
share for the same period in 2005.

    Net interest income for the quarter was $36.4 million, an increase of $3.4
million, or 10.2% over a year ago. The company's earning assets were $3.1
billion, an increase of $293.6 million, or 10.6% over September 30, 2005. Loans
were up $65.8 million from the third quarter of 2005. The growth in loans and
earning assets was supported by core deposit growth of $286.7 million. The loan
loss provision was $315,000 down $558,000 from the same period a year ago.
Nonperforming and restructured assets, 0.38% of assets, and third quarter net
charge-offs, 0.01% of loans, remain at historically low levels. Noninterest
income totaled $15.5 million, an increase of $615,000 or 4.1% over the third
quarter of 2005. The increase is due to growth in revenues from Trust,
electronic banking services, and securities gains from venture capital
activities. Noninterest expenses were $31.6 million, a decrease of $1.6 million
or 4.9%. Noninterest expense for the third quarter of 2005 included a one time
write-off of a $3 million receivable. Net of this write-off, expenses increased
$1.4 million or 4.5% and was due to growth and expansion of the branch delivery
system.

    The Company is expanding its branch delivery system, primarily in the
metropolitan areas of Oklahoma City and Tulsa. A new branch in south Oklahoma
City, 134th and May Avenue, opened in August. Construction of new branches are
underway in eastern Oklahoma County and in south Tulsa which are expected to
open in late 2006 or early 2007.

    The Company also completed the acquisition of First Bartlesville Bank,
Bartlesville, Oklahoma effective August 4, 2006. First Bartlesville Bank had
total assets of $45.3 million and deposits of $39.4 million as of September 30.
First Bartlesville Bank will be merged into BancFirst in early December 2006.

    BancFirst and Pickard Limited Partnership have entered into an agreement to
sell their ownership in Century Life Assurance Company, 75% and 25%,
respectively, to American Underwriters Life Insurance Company. Pickard Limited
Partnership is an affiliate of BancFirst Corporation. The transaction is
expected to be completed in the fourth quarter, subject to regulatory approvals.
The sale will result in an after-tax gain approximating $400,000 to $600,000,
and will not have a significant impact on its results of operations for 2007.

    At September 30, 2006 BancFirst Corporation had total assets of $3.4
billion, an increase of $347 million or 11.3% over a year ago. Loans totaled
$2.3 billion and deposits were $3.0 billion. The Company's stockholders equity
was $335 million, or 9.79% of total assets.

    BancFirst Corporation is an Oklahoma based financial services holding
company. The Company's principal subsidiary bank, BancFirst, is Oklahoma's
largest state-chartered bank with 85 banking locations serving 47 communities
across Oklahoma.
