EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES

     We maintain disclosure controls and procedures that are designed to ensure
that information required to be disclosed in our Exchange Act reports is
recorded, processed, summarized and reported within the time periods specified
in the SEC's rules and forms, and that such information is accumulated and
communicated to our management, including our CEO and CFO, as appropriate, to
allow timely decisions regarding required disclosure. In designing and
evaluating the disclosure controls and procedures, management recognized that
any controls and procedures, no matter how well designed and operated, can
provide only reasonable assurance of achieving the desired control objectives.

     We conducted an evaluation (the "Evaluation") as of the end of the period
covered by this annual report of the effectiveness of the design and operation
of our disclosure controls and procedures under the supervision and with the
participation of our management, including our CEO and CFO. Based upon the
Evaluation, our CEO and CFO have concluded that, subject to the limitations
noted below, our disclosure controls and procedures are effective to ensure that
material information relating to The Banc Corporation and its subsidiaries is
made known to management, including the CEO and CFO, particularly during the
period when our periodic reports are being prepared.

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

     Section 404 of the Sarbanes-Oxley Act of 2002 requires public companies, in
their annual reports on Form 10-K, to provide reports on their management's
assessment of such companies' internal control over financial reporting and for
such companies' independent registered public accountants to attest to such
reports by management. Our management is responsible for establishing and
maintaining adequate internal control over financial reporting, as defined in
Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. Our
internal control over financial reporting is designed to provide reasonable
assurance regarding the reliability of financial reporting and the preparation
of financial statements for external purposes in accordance with generally
accepted accounting principles, and includes those policies and procedures that

     - Pertain to the maintenance of records that, in reasonable detail,
       accurately and fairly reflect the transactions and dispositions of our
       assets;

     - Provide reasonable assurance that transactions are recorded as necessary
       to permit preparation of financial statements in accordance with GAAP,
       and that our receipts and expenditures are being made only in accordance
       with authorizations of our management and directors; and

     - Provide reasonable assurance regarding prevention or timely detection of
       unauthorized acquisition, use or disposition of our assets that could
       have a material effect on the financial statements.

     Our management has implemented a process to monitor and assess both the
design and operating effectiveness of our internal control over financial
reporting. Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness as to future financial reporting periods are subject
to the risk that controls may become

                                        3
<PAGE>

inadequate because of changes in conditions or that the degree of compliance
with the policies and procedures may deteriorate.

     Under the supervision of and with the participation of our Chief Executive
Officer and Chief Financial Officer, management has conducted a review,
evaluation and assessment of the effectiveness of our internal control over
financial reporting as of December 31, 2004, using the criteria set forth for
effective internal control over financial reporting as described in Internal
Control -- Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on such review, evaluation and
assessment, our management believes that we maintained effective internal
control over financial reporting as of December 31, 2004.

     Our independent registered public accounting firm, Carr, Riggs & Ingram
LLC, has issued an attestation report on such management's assessment, which is
set forth below.

            REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders of The Banc Corporation:

     We have audited management's assessment, included in the accompanying
Management's Report on Internal Control Over Financial Reporting, that The Banc
Corporation and Subsidiaries (Corporation) maintained effective internal control
over financial reporting as of December 31, 2004, based on criteria established
in Internal Control -- Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). The Corporation's
management is responsible for maintaining effective internal control over
financial reporting and for its assessment of the effectiveness of internal
control over financial reporting. Our responsibility is to express an opinion on
management's assessment and an opinion on the effectiveness of the Corporation's
internal control over financial reporting based on our audit.

     We conducted our audit in accordance with the standards of the Public
Company Accounting Oversight Board (United States). Those standards require that
we plan and perform the audit to obtain reasonable assurance about whether
effective internal control over financial reporting was maintained in all
material respects. Our audit included obtaining an understanding of internal
control over financial reporting, evaluating management's assessment, testing
and evaluating the design and operating effectiveness of internal control, and
performing such other procedures as we considered necessary in the
circumstances. We believe that our audit provides a reasonable basis for our
opinion.

     A company's internal control over financial reporting is a process designed
to provide reasonable assurance regarding the reliability of financial reporting
and the preparation of financial statements for external purposes in accordance
with generally accepted accounting principles. A company's internal control over
financial reporting includes those policies and procedures that (1) pertain to
the maintenance of records that, in reasonable detail, accurately and fairly
reflect the transactions and dispositions of the assets of the company; (2)
provide reasonable assurance that transactions are recorded as necessary to
permit preparation of financial statements in accordance with generally accepted
accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of
the company; and (3) provide reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use, or disposition of the company's
assets that could have a material effect on the financial statements.

     Because of its inherent limitations, internal control over financial
reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the
degree of compliance with the policies or procedures may deteriorate.

     In our opinion, management's assessment that The Corporation maintained
effective internal control over financial reporting as of December 31, 2004, is
fairly stated, in all material respects, based on criteria established in
Internal Control -- Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). Also in our opinion, The
Corporation maintained, in all material respects, effective internal control
over financial reporting as of December 31, 2004, based on criteria established
in Internal Control -- Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO).

     We have also audited, in accordance with the standards of the Public
Company Accounting Oversight Board (United States), the consolidated statement
of financial condition as of December 31, 2004 and the related consolidated
statements of operations, changes in stockholders' equity, and cash flows for
the year then ended of The Corporation, and our report dated March 15, 2005,
expressed an unqualified opinion.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

     During the quarter ended December 31, 2004, there were no changes in our
internal control over financial reporting identified in connection with
management's evaluation of internal control over financial reporting as of
December 31, 2004 that have materially affected, or are reasonably likely to
materially affect, our internal control over financial reporting.

10A-3(b)(1) under the Securities Exchange Act of 1934. The Board of Directors
has determined that Mr. Barker qualifies as an "audit committee financial
expert", under the Rules of the Securities and Exchange Commission. In January
2004, the Board of Directors adopted a revised Audit Committee Charter, a copy
of which was attached as Appendix A to the Proxy Statement relating to our 2004
Annual Meeting of Stockholders.

COMPENSATION COMMITTEE

     The Compensation Committee is responsible for reviewing the performance of
all of our officers and recommending to the Board of Directors annual salary and
bonus amounts for them. The Compensation Committee also administers the Third
Amended and Restated 1998 Incentive Stock Plan of The Banc Corporation and the
Commerce Bank of Alabama Stock Option Plan. The Compensation Committee currently
comprises Messrs. Barker, Smith and Stephens, all of whom are independent
directors as defined under NASDAQ Rule 4200. During 2004, the Compensation
Committee held four meetings.

NOMINATING COMMITTEE

     The Nominating Committee recommends to the Board of Directors and evaluates
potential candidates to serve as directors of The Banc Corporation. The
Nominating Committee was established in March 2004 and consists of Messrs.
Barker, Smith and Stephens. Each of the members of the Nominating Committee is
an independent director, as defined under NASDAQ Rule 4200. The Nominating
Committee met once during 2004.

     The Nominating Committee has a written charter, adopted by the Board in
March 2004, which was attached as Appendix B to the Proxy Statement relating to
our 2004 Annual Meeting of Stockholders. The Nominating Committee is charged
with developing and recommending criteria to be considered in identifying and
evaluating potential candidates to serve as directors of The Banc Corporation as
well as establishing policies and procedures for identifying, recruiting,
interviewing and recommending to the Board qualified candidates to serve as
directors. The Committee will also develop and recommend to the Board criteria
to be used in reviewing and evaluating candidates recommended by shareholders of
The Banc Corporation and is responsible for reviewing and evaluating such
candidates and making recommendations to the Board. The Nominating Committee is
currently developing such criteria, policies and procedures.

DIRECTOR COMPENSATION

     All non-employee directors receive $1,500 compensation for each meeting of
the board attended and a retainer of $1,500 per quarter for serving as
directors. In addition, all non-employee directors who are members of standing
or ad hoc committee of the Board of Directors receive $100 per committee
meeting. Directors are eligible to receive grants of stock options and
restricted stock under the Third Amended and Restated 1998 Stock Incentive Plan
of The Banc Corporation.

     The following directors have entered into Deferred Compensation Agreements
with us originally effective as of September 1, 1999: Andrews, Campbell, Carter,
Durden, Jernigan, Jr., Jones, Kent, Orso, Ripps, Stephens, Striplin, Swift,
Taylor and Taylor, Jr. Directors Taylor, Kent and Jernigan also have Deferred
Compensation Agreements with The Bank. With the exception of the agreements
relating to Mr. Taylor,

                                        9
<PAGE>

Mr. Taylor, Jr. and Mr. Carter, these agreements provide that we will establish
and fund investments in a Deferral Account for the director as provided in the
agreements. Upon termination of a director's service other than by reason of
death or following a change in control, we will pay the director within 60 days
of termination the amount equal to the Deferral Account Balance. If the director
is terminated following a change in control, we must pay the director the
primary and secondary benefits. The primary benefit is the Deferral Account
balance at the end of the plan year immediately preceding the director's
termination of service, which is payable to the director in ten equal annual
installments. The secondary benefit is the amount equal to the growth in the
Deferral Account and must be paid within 60 days of the end of each plan year.
The agreements relating to Mr. Taylor, Mr. Taylor, Jr. and Mr. Carter were
amended in 2004 to provide for payment of a defined benefit based on
then-current projections rather than the variable benefit applicable to the
other directors.

CODE OF ETHICS

     We have adopted a code of ethics that applies to all of our employees,
including our principal executive, financial and accounting officers. A copy of
our code of ethics is available on our website. We intend to disclose
information about any amendments to, or waivers from, our code of ethics that
are required to be disclosed under applicable Securities and Exchange Commission
regulations by providing appropriate information on our website. If at any time
our code of ethics is not available on our website, we will provide a copy of it
free of charge upon written request.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934 requires our officers
and directors and persons who beneficially own more than 10% of a registered
class of our equity securities, to file reports of ownership and changes in
ownership with the Securities and Exchange Commission. Officers, directors and
beneficial owners of more than 10% of our common stock are required by SEC
regulations to furnish The Banc Corporation with copies of all Section 16(a)
forms that they file. Based on a review of the copies of the forms furnished to
us, or written representations that no reports on Form 5 were required, we
believe that during 2004, all of our officers, directors and greater-than-10%
beneficial owners complied with all applicable filing requirements except Roger
D. Barker, an outside director. Due to an inadvertent error in obtaining his
electronic filing codes from the Securities and Exchange Commission, Mr. Barker
did not timely file his Form 3, which was due in December 2003, and a report on
Form 4 due June 17, 2004, relating to grants of stock options covering an
aggregate of 5,000 shares.

    maintained by The Banc Corporation.
(4) During the first quarter of 2002, The Banc Corporation transferred to Mr.
    Taylor a 50% interest in the key man life insurance policy The Banc
    Corporation maintains on Mr. Taylor. This amount includes the cash value of
    50% of the insurance policy transferred to Mr. Taylor during the first
    quarter of 2002, 50% of the cost of the insurance policy premiums plus a
    "gross-up" payment to make the transaction tax neutral to Mr. Taylor. Mr.
    Taylor had no life insurance policy prior to this transfer even though his
    employment agreements beginning in 1997 have provided for a life insurance
    policy. These amounts were non-cash compensation.

(1) This number excludes 142,500 shares of restricted stock granted under the
    Third Amended and Restated 1998 Stock Incentive Plan of The Banc
    Corporation.
(2) Shares authorized and issued under the Commerce Bank of Alabama Stock Option
    Plan, which we assumed in the merger with Commerce Bank of Alabama in
    November 1998. We do not intend to grant any additional options under this
    plan.

     Third Amended and Restated 1998 Stock Incentive Plan.  The objectives of
the Third Amended and Restated 1998 Stock Incentive Plan of The Banc Corporation
are to further our growth and development by (i) encouraging selected
participants who contribute or are expected to contribute materially to our
success to obtain shares of our common stock and to encourage them to promote
our best interests and (ii) affording us a means of attracting qualified
personnel. The plan authorizes the grant of incentive stock options,
nonqualified stock options and other awards, including stock appreciation
rights, restricted stock and performance shares. The plan covers 2,500,000
shares of our common stock. As of December 31, 2004, the Compensation Committee
has granted options to purchase 1,625,500 shares of our common stock and
restricted stock awards covering 142,500 shares of our common stock which remain
outstanding. Those shares may be, in whole or in part, authorized but unissued
shares or issued shares that we have reacquired.

     Our Compensation Committee, which administers the Third Amended and
Restated 1998 Stock Incentive Plan, may grant options or other awards to
employees, officers, directors, consultants, agents, independent contractors and
other persons who contributed or are expected to contribute materially to our
success. The Compensation Committee, subject to the approval of the board of
directors and the provisions of the plan, has full power to determine the types
of awards to be granted, to select the individuals to whom awards will be
granted, to fix the number of shares that each optionee may purchase, to set the
terms and conditions of each option, and to determine all other matters relating
to the plan.

     The Commerce Bank of Alabama Stock Incentive Compensation Plan.  We assumed
the Commerce Bank of Alabama Incentive Compensation Plan in our acquisition of
Commerce Bank of Alabama on November 6, 1998. This plan authorized the grant of
incentive and nonqualified options to purchase common stock of The Banc
Corporation. As of December 31, 2004, there were options outstanding under this
plan to purchase 29,009 shares of common stock at a price of $6.24 per share. We
have not granted and do not intend to grant any additional options under this
plan.

EMPLOYMENT AGREEMENTS

     C. Stanley Bailey.  Mr. Bailey and The Banc Corporation have entered into
an Employment Agreement, dated January 24, 2005, under which The Banc
Corporation has agreed to employ Mr. Bailey as Chief Executive Officer of The
Banc Corporation and The Bank for a term expiring January 31, 2008. The
Employment Agreement automatically renews for successive one-year extensions on
each anniversary of the commencement of the term unless either party gives the
other 30 days' prior written notice of nonrenewal. Under the Employment
Agreement, Mr. Bailey is entitled to an initial base salary at the annual rate
of $400,000 per year and to an annual target bonus of 50% of his base salary,
subject to the achievement of agreed-upon performance goals. Mr. Bailey is also
entitled to participate in other bonus or long-term incentive plans applicable
to similarly situated executive officers, and to participate in such insurance,
medical and other employee benefit plans as may be provided to such executive
officers. The Banc Corporation is also required to provide Mr. Bailey with
certain other benefits, including a term life insurance policy in the amount of
at least $1 million, an automobile and customary automobile-related benefits,
and initiation fees, dues and assessments for approved club memberships, and to
pay certain relocation expenses. The agreement restricts Mr. Bailey's ability to
engage in various activities competitive with The Banc Corporation's business
for one year after Mr. Bailey ceases to be employed by The Banc Corporation.

     If Mr. Bailey's employment is terminated other than for Cause (as defined)
or as a result of his death or disability, or if Mr. Bailey terminates the
agreement as a result of certain adverse changes in his functions, duties or
responsibilities or of another material breach by The Banc Corporation of its
obligations, Mr. Bailey is entitled to continued compensation at the
then-current rate (including bonus compensation) for the then-remaining term of
the agreement, provided that Mr. Bailey may elect to receive such payment in a
lump sum

                                        13
<PAGE>

discounted to present value using a 6% discount rate, and to the continuation of
other benefits during such remaining term. If Mr. Bailey's employment is
terminated as a result of his disability, he is entitled to continued
compensation at his then-current rate (including bonus compensation) and the
continuation of other benefits for one year. If Mr. Bailey's employment by The
Banc Corporation is terminated within two years following a Change in Control
(as defined), other than for Cause or as a result of his death, disability or
retirement, or if Mr. Bailey terminates such employment following the occurrence
of specified events within two years after a Change in Control, Mr. Bailey will
be entitled to receive a lump sum payment equal to three times the sum of (i)
his then-current base salary plus (ii) the target bonus he would have been
entitled to receive, and he will be entitled to receive other benefits specified
in the agreement. In addition, he will be entitled to a gross-up payment equal
to the amount of any excise taxes imposed upon him as a result of such payments
upon termination following a Change in Control.

     The agreement obligates The Banc Corporation to appoint Mr. Bailey to the
Board of Directors of The Banc Corporation, and further provides that Mr. Bailey
will be appointed as Chairman of the Board of The Banc Corporation at such time,
if any, as James A. Taylor ceases to serve as Chairman of the Board.

     C. Marvin Scott and Rick D. Gardner.  Mr. Scott and Mr. Gardner have
entered into employment agreements with The Banc Corporation and the Bank
providing for terms substantially identical to those described above with
respect to Mr. Bailey, except that (a) Mr. Scott's initial annual base salary is
$300,000 and Mr. Gardner's initial annual base salary is $250,000; (b) The Banc
Corporation is obligated to provide term life insurance policies to Mr. Scott in
the amount of $750,000 and to Mr. Gardner in the amount of $600,000; and (c)
each of Mr. Scott and Mr. Gardner will be appointed as a director of The Banc
Corporation effective on or before December 31, 2005, if then permitted by the
NASDAQ Stock Market Marketplace Rules, or, if not so permitted on or before
December 31, 2005, then as soon thereafter as is permitted by the NASDAQ Stock
Market Marketplace Rules.

     Stock Option Grants to Messrs. Bailey, Scott and Gardner.  Under their
respective employment agreements, The Banc Corporation is obligated to grant,
and has granted as of January 24, 2005, options to acquire 711,970 shares of
common stock to Mr. Bailey, 355,985 shares to Mr. Scott, and 355,985 shares to
Mr. Gardner, each at an exercise price of $8.17 per share, the market price on
the date of grant. Such options have a ten-year term. Such options vest and
become exercisable as follows:

     - 50% on April 24, 2005;

     - 20% on the later of (x) the date on which the average closing price per
       share of The Banc Corporation common stock over a
       15-consecutive-trading-day period (the "Market Value price") is at least
       $10 but less than $12, and (y) June 29, 2005 (the "Alternate Vesting
       Date");

     - 15% on the later of (x) the date on which the Market Value price is at
       least $12 but less than $14, and (y) the Alternate Vesting Date; and

     - 15% on the later of (x) the date on which the Market Value price is at
       least $14, and (y) the Alternate Vesting Date.

     - To the extent not otherwise vested, on January 24, 2010.

     If an executive's employment is terminated for any reason other than (i)
voluntarily by the executive (other than after a Change in Control) or (i) by
The Banc Corporation with Cause, (a) the portion of such options that becomes
vested on April 24, 2005 will immediately vest, to the extent not previously
vested, (b) if the Alternate Vesting Date has not occurred but any Market Value
price has been reached, the shares that would vest upon attainment of such
Market Value price will be immediately vested notwithstanding that the Alternate
Vesting Date has not yet occurred, and (c) vesting will continue through any
remaining term of the employment agreement in accordance with its terms.

     David R. Carter.  We have entered into an employment agreement with David
R. Carter, effective as of September 19, 2000. Under his employment agreement,
Mr. Carter serves as the Executive Vice President and Chief Financial Officer of
The Banc Corporation and Executive Vice President and Chief Financial Officer of
The Bank. Mr. Carter will receive a base salary of $243,500 per year plus an
incentive payment of
                                        14
<PAGE>

5% of the base amount per quarter. He is also entitled to receive other
benefits, including a car allowance and country club or athletic club dues, and
may participate in all other executive compensation plans. The term of the
agreement is three years, which is renewable daily for an additional three-year
period. If Mr. Carter is terminated for any reason other than "cause" as defined
in the agreement (including constructive termination), he shall receive three
years' base compensation, directors' fees and all benefits or their cash
equivalents. He would be entitled to a "gross up" payment to cover any excise
tax imposed on any severance payment to him.

     F. Hampton McFadden, Jr.  We have entered into an employment agreement with
F. Hampton McFadden, Jr. effective as of January 15, 2001. Under his employment
agreement, Mr. McFadden serves as the Executive Vice President and General
Counsel and Secretary of The Banc Corporation and The Bank. Mr. McFadden will
receive a base salary of $220,000 per year plus an incentive payment of 5% of
the base amount per quarter. He is also entitled to receive other benefits,
including a car allowance and country club or athletic club dues, and may
participate in all other executive compensation plans. The term of the agreement
is three years, which is renewable daily for an additional three-year period. If
Mr. McFadden is terminated for any reason other than "cause" as defined in the
agreement (including constructive termination), he shall receive three years'
base compensation and all benefits or their cash equivalents. He would be
entitled to a "gross up" payment to cover any excise tax imposed on any
severance payment to him.

     Standstill Agreements with Messrs. Carter and McFadden.  In addition, on
January 24, 2005, we entered into certain Employment Agreement Standstill
Agreements ("standstill agreements") with Messrs. Carter and McFadden (the
"executives"). The management changes described above gave the executives the
right to exercise certain provisions under their employment agreements. Under
the standstill agreements, the executives have agreed to remain in their present
positions and their employment agreements remain in full force. We and the
executives have agreed as part of the standstill agreements to discuss any
proposed changes in the executives' continued employment relationship with us.
At any time following the first anniversary of the standstill agreements, if we
and the executive have not reached a new agreement, such executive may terminate
his employment for any reason and receive all rights, payments, privileges and
benefits currently provided for under his employment agreement.

     Deferred Compensation Agreements.  We have entered into deferred
compensation agreements with Messrs. Carter, McFadden, Taylor and Taylor, Jr.
These agreements provide that we will pay the executive officers a defined
benefit over a period of years following their attainment of the retirement age
specified in the individual agreements, subject to applicable vesting periods.
In general, the vested percentages are payable whether or not the executive
remains employed through such retirement age.

PRIOR EMPLOYMENT AGREEMENTS WITH JAMES A. TAYLOR AND JAMES A. TAYLOR, JR.

     The Banc Corporation was a party to an Employment Agreement, dated January
1, 2002, with James A. Taylor, formerly Chairman of the Board and Chief
Executive Officer of The Banc Corporation, and an Employment Agreement, dated
September 19, 2000, with James A. Taylor, Jr., formerly President and Chief
Operating Officer of The Banc Corporation. These agreements are described in The
Banc Corporation's previous filings with the Securities and Exchange Commission,
including The Banc Corporation's Proxy Statement in connection with its 2004
Annual Meeting of Stockholders. Under these agreements, the transactions
described above triggered various obligations of The Banc Corporation to Mr.
Taylor and Mr. Taylor, Jr. In order to resolve certain issues that arose in the
construction of provisions of the agreements and to facilitate the equity
investment and management transition described above, Mr. Taylor and Mr. Taylor,
Jr. engaged in discussions with a committee of independent directors appointed
by The Banc Corporation's Board of Directors and, after such discussions,
entered into new agreements with The Banc Corporation which supersede the
obligations of The Banc Corporation under their employment agreements and which
provide for payments to Mr. Taylor of a lesser amount over a longer period of
time than would have been provided for under his employment agreement. Material
terms of the new agreements are described below.

                                        15
<PAGE>

     Agreement with James A. Taylor.  The Banc Corporation's employment
agreement with Mr. Taylor entitled him to certain payments based on his current
compensation upon the occurrence of specified circumstances, and gave him the
option to demand the discounted present value of such payments in a lump sum.
The transactions described above would have triggered The Banc Corporation's
obligations to make such payments to Mr. Taylor. On January 24, 2005, The Banc
Corporation entered into an agreement with Mr. Taylor that provided that, in
lieu of the payments to which he would have been entitled under his employment
agreement, The Banc Corporation would pay to Mr. Taylor $3,940,154.90 on January
24, 2005, $3,152,123.92 on January 24, 2006, and $788,030.98 on January 24,
2007. The agreement also provides for the provision of certain insurance
benefits to Mr. Taylor, the transfer of a "key man" life insurance policy to Mr.
Taylor, and the maintenance of such policy by The Banc Corporation for five
years (with the cost of maintaining such policy included in the above amounts),
in each case substantially as required by his employment agreement. The Banc
Corporation's obligation to provide such payments and benefits to Mr. Taylor is
absolute and will survive the death or disability of Mr. Taylor.

     The agreement provides for various covenants by Mr. Taylor that were not
contained in his employment agreement, including an agreement that Mr. Taylor
will not engage in specified activities that are or could be competitive with
the business of The Banc Corporation or The Bank so long as he is receiving any
benefits under the agreement or providing services to The Banc Corporation or
the Bank, as a director, consultant, employee or otherwise, and an agreement
that he will not sell any shares of The Banc Corporation's common stock or other
securities of The Banc Corporation for a year without the prior written consent
of The Banc Corporation. The agreement also contains customary covenants by Mr.
Taylor concerning noninterference, nonsolicitation and nondisparagement. Mr.
Taylor is permitted to be a passive investor (a) owning up to 5% of publicly
traded entities which may be competitors of The Banc Corporation or The Bank and
(b) owning up to 10% of any bank(s) in which James A. Taylor, Jr. acts in an
executive capacity, in each case without relinquishing his position as Chairman
and a director of The Banc Corporation.

     Mr. Taylor will continue to serve as non-executive Chairman of the Board of
The Banc Corporation until January 2007.

     Agreement with James A. Taylor, Jr.  The Banc Corporation's employment
agreement with Mr. Taylor, Jr. entitled him to certain payments based on his
current compensation upon the occurrence of specified circumstances, and gave
him the option to demand the discounted present value of such payments in a lump
sum. The transactions described above would have triggered The Banc
Corporation's obligations to make such payments to Mr. Taylor, Jr. On January
24, 2005, The Banc Corporation entered into an agreement with Mr. Taylor, Jr.
that provided that, in lieu of the payments to which he would have been entitled
under his employment agreement, The Banc Corporation would pay to Mr. Taylor,
Jr., $1,382,872.17 on January 24, 2005. The agreement also provides for the
provision of certain insurance benefits to Mr. Taylor, Jr. and for the immediate
vesting of his unvested incentive awards and deferred compensation in each case
substantially as required by his employment agreement. The Banc Corporation's
obligation to provide such payments and benefits to Mr. Taylor, Jr. is absolute
and will survive the death or disability of Mr. Taylor.

     The agreement provides for various covenants by Mr. Taylor, Jr. that were
not contained in his employment agreement, including an agreement that Mr.
Taylor, Jr. will not engage in specified activities that are or could be
competitive with the business of The Banc Corporation or The Bank so long as he
is receiving any benefits under the agreement or providing services to The Banc
Corporation or the Bank, as a director, consultant, employee or otherwise, and
an agreement that he will not sell any shares of The Banc Corporation's common
stock or other securities of The Banc Corporation for a year without the prior
written consent of The Banc Corporation. The agreement also contains customary
covenants by Mr. Taylor, Jr. concerning noninterference, nonsolicitation and
nondisparagement. Mr. Taylor, Jr. is permitted to be a passive investor owning
up to 5% of publicly traded entities which may be competitors of The Banc
Corporation or The Bank.

     Mr. Taylor, Jr. will continue to serve as a director of The Banc
Corporation until January 2006 subject to the following limitations. The
agreement acknowledges that Mr. Taylor, Jr. may in the future serve as an

                                        16
<PAGE>

investor, director and officer of a de novo bank or bank(s) in certain specified
areas, but provides that he must resign as a director of The Banc Corporation
immediately upon initiating any such undertaking.

ITEM 13.  CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS.

     The Banc Corporation and The Bank have entered into transactions with
certain directors or officers of The Banc Corporation or their affiliates. Such
transactions were made in the ordinary course of business on substantially the
same terms and conditions, including interest rates and collateral, as those
prevailing at the same time for comparable transactions with other customers,
and did not, in the opinion of management involve more than normal credit risk
or present other unfavorable features.

     Brett Taylor was the vice president of Morris Avenue Management Group,
Inc., a wholly-owned subsidiary of The Banc Corporation until April 30, 2005.
Mr. Taylor's salary for 2004 was $80,355. Mr. Taylor is the son of James A.
Taylor and the brother of James A. Taylor, Jr.

     The law firm of Campbell and Douglas performed legal services for The Bank
in Sylacauga, Alabama during 2004 and received fees of $6,192 for such services.
W. T. Campbell, Jr., is a partner of Campbell and Douglas. It is anticipated
that Mr. Campbell will continue to perform legal services for The Bank in
Sylacauga, Alabama from time to time.

     The Mailon Kent Insurance Agency received commissions of approximately
$180,400 from the sale of insurance to The Banc Corporation during 2004.

     The Banc Corporation believes that all the foregoing transactions were made
on terms and conditions reflective of arms' length transactions.
