                               SEVERANCE AGREEMENT

     This SEVERANCE AGREEMENT (this "Agreement") is entered into this 1st day of
August, 2002, by and between Unizan Financial Corp., an Ohio corporation (the
"Corporation"), and Roger L. Mann, President and Chief Executive Officer of the
Corporation (the "Executive"), and Chairman of Unizan Bank, National
Association, a national bank and wholly owned subsidiary of the Corporation (the
"Bank").

     WHEREAS, the Executive is a senior executive of the Corporation, is
employed by the Corporation and the Bank, and has made and is expected to
continue to make major contributions to the profitability, growth and financial
strength of the Corporation and the Bank,

     WHEREAS, the Corporation recognizes that, as is the case for most
companies, the possibility of a Change in Control (as defined in Section 1(c))
exists,

     WHEREAS, the Corporation desires to assure itself of the current and future
continuity of management and desires to establish minimum severance benefits for
certain of its officers and other key employees, including the Executive, if a
Change in Control occurs,

     WHEREAS, the Corporation wishes to ensure that officers and other key
employees are not practically disabled from discharging their duties if a
proposed or actual transaction involving a Change in Control arises,

     WHEREAS, the Corporation desires to provide additional inducement for the
Executive to continue to remain in the ongoing employ of the Corporation and the
Bank,

     WHEREAS, the Corporation's predecessor, UNB Corp., and the Executive
entered into a severance agreement dated May 8, 2001, as amended February 8,
2002, providing for severance and termination benefits if the Executive is
terminated without cause or if the Executive terminates voluntarily for good
reason within three years after a change in control of UNB Corp., or if the
Executive terminates voluntarily with or without good reason during a 90-day
period beginning on the date that is six months after a change in control,

     WHEREAS, on March 7, 2002 the predecessor of the Corporation, UNB Corp.,
and BancFirst Ohio Corp. completed a merger transaction whereby BancFirst Ohio
Corp. merged with and into UNB Corp. under the terms of the September 5, 2001
Agreement of Merger and Plan of Reorganization,

     WHEREAS, the merger of BancFirst Ohio Corp. with and into UNB Corp.
constituted a change in control under the terms of the May 8, 2001 severance
agreement between the Executive and UNB Corp.,

     WHEREAS, as an inducement for BancFirst Ohio Corp. to enter into the
September 5, 2001 Agreement of Merger and Plan of Reorganization, the Executive
agreed to waive his right under section 1(b) of the May 8, 2001 severance
agreement to claim severance and termination benefits for voluntary termination
without good reason during the 90-day period beginning on the date that is six
months after the merger with BancFirst Ohio Corp., which waiver agreement on the
part of the Executive is set forth in the February 8, 2002 amendment of his May
8, 2001 severance agreement,

     WHEREAS, consistent with the terms of the May 8, 2001 severance agreement,
as successor to UNB Corp. the Corporation became a party to and assumed UNB
Corp.'s obligations under the May 8, 2001 severance agreement, as amended,

     WHEREAS, the Corporation and the Executive have negotiated and agreed to
certain changes in the terms and conditions for severance and termination
benefits payable under the May 8, 2001 severance agreement, as amended, entered
into by UNB Corp. and the Executive,

     WHEREAS, the changes the Corporation and the Executive have agreed to
include but are not limited to (1) elimination of the Executive's right to
severance and termination benefits if he terminates voluntarily and without good
reason during a specified period after a change in control, (2) changing the
provision of the severance



<PAGE>


agreement having to do with renewal and extension of its term so that the term
of the severance agreement shall be extended solely by affirmative action of the
board of directors, rather than extending for another year automatically unless
the board of directors determines that it shall not be extended, (3) preserving
the Executive's right to severance and termination benefits if he is
involuntarily terminated without cause or if he voluntarily terminates for good
reason within three years after the March 7, 2002 change in control represented
by the merger between UNB Corp. and BancFirst Ohio Corp., regardless of whether
another change in control occurs after the date of this Agreement, and (4)
revising the definition of "good reason," which governs the circumstances under
which the Executive may terminate employment voluntarily and be entitled to
severance and termination benefits,

     WHEREAS, the Corporation and the Executive intend that this Agreement shall
supersede and replace in its entirety the May 8, 2001 severance agreement, as
amended, and

     WHEREAS, none of the conditions or events included in the definition of the
term "golden parachute payment" that is set forth in section 18(k)(4)(A)(ii) of
the Federal Deposit Insurance Act [12 U.S.C. 1828(k)(4)(A)(ii)] and in Federal
Deposit Insurance Corporation Rule 359.1(f)(1)(ii) [12 CFR 359.1(f)(1)(ii)]
exists or, to the best knowledge of the Corporation and the Bank, is
contemplated insofar as either of the Corporation or the Bank is concerned.

     NOW THEREFORE, in consideration of these premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

1.   CHANGE IN CONTROL / EMPLOYMENT TERMINATION

     (a) TERMINATION OF THE EXECUTIVE WITHIN THREE YEARS AFTER A CHANGE IN
CONTROL. If a Change in Control occurs during the term of this Agreement and if
either of the following occurs, the Executive shall be entitled to severance and
termination benefits specified in Section 2 and legal fee payment benefits
specified in Section 7 of this Agreement --

     (1)  Termination by the Corporation or the Bank: the Executive's employment
          with the Corporation or the Bank is involuntarily terminated within
          three years after a Change in Control, except for termination under
          Section 4 of this Agreement, or

     (2)  Termination by the Executive for Good Reason: the Executive terminates
          his employment with the Corporation or the Bank for Good Reason (as
          defined in Section 3) within three years after a Change in Control.

     If the Executive is removed from office or if his employment terminates
after discussions with a third party regarding a Change in Control commence, and
if those discussions ultimately conclude with a Change in Control, then for
purposes of this Agreement the removal of the Executive or termination of his
employment shall be deemed to have occurred after the Change in Control.

     (b) TERMINATION OF THE EXECUTIVE ON OR BEFORE MARCH 7, 2005. Regardless of
whether a Change in Control occurs during the term of this Agreement, if either
of the following events occurs on or before March 7, 2005 the Executive shall be
entitled to severance and termination benefits specified in Section 2 and legal
fee payment benefits specified in Section 7 of this Agreement --

     (1)  Termination by the Corporation or the Bank: the Executive's employment
          is involuntarily terminated, except for termination under Section 4 of
          this Agreement, or

     (2)  Termination by the Executive for Good Reason: the Executive terminates
          his employment with the Corporation or the Bank for Good Reason (as
          defined in Section 3). For purposes of this subsection 1(b)(2), the
          term "Change in Control" as used in Section 3 includes the March 7,
          2002 merger of BancFirst Ohio Corp. with and into UNB Corp.




                                       2
<PAGE>


          under the terms of the September 5, 2001 Agreement of Merger and Plan
          of Reorganization,


     (c) DEFINITION OF CHANGE IN CONTROL. For purposes of this Agreement,
"Change in Control" means any of the following events occur--

     (1)  Merger: the Corporation merges into or consolidates with another
          corporation, or merges another corporation into the Corporation, and
          as a result less than a majority of the combined voting power of the
          resulting corporation immediately after the merger or consolidation is
          held by persons who were the holders of the Corporation's voting
          securities immediately before the merger or consolidation. For
          purposes of this Agreement, the term person means an individual,
          corporation, partnership, trust, association, joint venture, pool,
          syndicate, sole proprietorship, unincorporated organization or other
          entity,

     (2)  Acquisition of Significant Share Ownership: a report on Schedule 13D
          or Schedule TO (or any successor schedule, form or report) is filed or
          is required to be filed under Sections 13(d) or 14(d) of the
          Securities Exchange Act of 1934, if the schedule discloses that the
          filing person or persons acting in concert has or have become the
          beneficial owner of 15% or more of a class of the Corporation's voting
          securities (but this clause (2) shall not apply to beneficial
          ownership of voting shares of the Corporation held by a Subsidiary
          (defined as an entity in which the Corporation directly or indirectly
          beneficially owns 50% or more of the outstanding voting securities) of
          the Corporation in a fiduciary capacity),

     (3)  Change in Board Composition: during any period of two consecutive
          years, individuals who constitute the Corporation's board of directors
          at the beginning of the two-year period cease for any reason to
          constitute at least a majority thereof; provided, however, that-- for
          purposes of this clause (3)-- each director who is first elected by
          the board (or first nominated by the board for election by
          shareholders) by a vote of at least two-thirds (2/3) of the directors
          who were directors at the beginning of the period shall be deemed to
          have been a director at the beginning of the two-year period, or

     (4)  Sale of Assets: the Corporation sells to a third party substantially
          all of the Corporation's assets. For purposes of this Agreement, sale
          of substantially all of the Corporation's assets includes sale of the
          Bank.

2.   SEVERANCE AND TERMINATION BENEFITS

     (a) SEVERANCE AND TERMINATION BENEFITS. The severance and termination
benefits to which the Executive is entitled under Section 1 are as follows--

     (1)  Lump Sum Payment: the Corporation shall make a lump sum payment to the
          Executive in an amount in cash equal to three times the Executive's
          annual compensation. For purposes of this Agreement, annual
          compensation means (a) the Executive's then current annual base salary
          at the date of Change in Control or the Executive's termination of
          employment (at whichever date the Executive's current annual base
          salary is greater), plus (b) the average of the bonuses or incentive
          compensation earned for the three calendar years immediately preceding
          the year in which the Change in Control occurs, regardless of when the
          bonus or incentive compensation earned for the preceding three
          calendar years is paid. As of the date this Agreement is entered into,
          the parties recognize that the bonus/incentive compensation earned by
          the Executive for a particular year's calendar service is paid by the
          Bank in the year following the calendar year in which such
          bonus/incentive compensation is earned. The amount payable to the
          Executive hereunder





                                       3
<PAGE>


          shall not be reduced to account for the time value of money or
          discounted to present value. The payment required under this Section
          2(a)(1) is payable no later than 5 business days after the date the
          Executive's employment terminates. If the Executive terminates
          employment for Good Reason, the date of termination shall be the date
          specified by the Executive in his notice of termination,

     (2)  Benefit Plans: the Corporation shall cause the Executive to become
          fully vested in any qualified and non-qualified plans, programs or
          arrangements in which the Executive participated, notwithstanding any
          provisions contained in the respective agreement of the plan, program
          or arrangement. The Corporation also shall contribute or cause the
          Bank to contribute to the Executive's 401(k) Plan account and his
          United National Bank & Trust Co. Employees Profit Sharing Plan account
          the matching and profit sharing contribution, if any, that would have
          been paid had the Executive's employment not terminated before the end
          of the plan year, and

     (3)  Insurance Coverage: the Corporation shall cause to be continued life,
          health and disability insurance coverage substantially identical to
          the coverage maintained for the Executive before his termination. The
          insurance coverage may cease when the Executive becomes employed by
          another employer or 36 months after the Executive's termination,
          whichever occurs first. At the end of the 36-month period, the
          Executive shall have the option to continue health insurance coverage
          at his own expense for a period not less than the number of months by
          which the Consolidated Omnibus Budget Reconciliation Act (COBRA)
          continuation period exceeds 36 months.

     (b) GROSS-UP FOR TAXES. Additional Payment to Account for Excise Taxes. If
the Executive becomes entitled to severance and termination benefits under this
Agreement, including accelerated vesting of stock options granted under the
Corporation's 1997 Stock Option Plan and 1987 Stock Option and Performance Unit
Plan and acceleration of benefits under any other benefit, compensation, or
incentive plan or arrangement with the Corporation or the Bank (collectively,
the "Total Benefits"), and if any part of the Total Benefits is subject to the
Excise Tax under section 280G and section 4999 of the Internal Revenue Code (the
"Excise Tax"), the Corporation shall pay to the Executive an amount (the
"Gross-Up Payment(s)") in addition to the amount set forth in Section 2(a) such
that -- after payment by the Executive of all taxes (including any Excise Tax,
income tax or payroll tax) imposed upon the Gross-Up Payment, together with any
interest or penalties imposed with respect to such taxes -- the Executive will
retain an amount of the Gross-Up Payment equal to the Excise Tax imposed upon
the Total Benefits.

     Calculating the Excise Tax. For purposes of determining whether any of the
Total Benefits will be subject to the Excise Tax and for purposes of determining
the amount of the Excise Tax,

     (1)  Determination of "Parachute Payments" Subject to the Excise Tax: any
          other payments or benefits received or to be received by the Executive
          in connection with a Change in Control or the Executive's termination
          of employment (whether under the terms of this Agreement or any other
          agreement, the 1997 Stock Option Plan and 1987 Stock Option and
          Performance Unit Plan or any other benefit plan or arrangement with
          the Corporation, the Bank, any person whose actions result in a Change
          in Control or any person affiliated with the Corporation or such
          person) shall be treated as "parachute payments" within the meaning of
          section 280G(b)(2) of the Internal Revenue Code, and all "excess
          parachute payments" within the meaning of section 280G(b)(1) shall be
          treated as subject to the Excise Tax, unless in the opinion of the
          certified public accounting firm that is retained by the Corporation
          as of the date immediately before the Change in Control (the
          "Accounting Firm") such other payments or benefits do not constitute
          (in whole or in part) parachute payments, or such excess parachute
          payments represent (in whole or in part) reasonable compensation for
          services actually rendered within the meaning of




                                       4
<PAGE>


          section 280G(b)(4) of the Internal Revenue Code in excess (as defined
          in section 280G(b)(3) of the Internal Revenue Code), or are otherwise
          not subject to the Excise Tax,


     (2)  Calculation of Benefits Subject to Excise Tax: the amount of the Total
          Benefits that shall be treated as subject to the Excise Tax shall be
          equal to the lesser of (a) the total amount of the Total Benefits
          reduced by the amount of such Total Benefits that in the opinion of
          the Accounting Firm are not parachute payments, or (b) the amount of
          excess parachute payments within the meaning of section 280G(b)(1)
          (after applying clause (1), above), and

     (3)  Value of Noncash Benefits and Deferred Payments: the value of any
          noncash benefits or any deferred payment or benefit shall be
          determined by the Accounting Firm in accordance with the principles of
          sections 280G(d)(3) and (4) of the Internal Revenue Code.

     Assumed Marginal Income Tax Rate. For purposes of determining the amount of
the Gross-Up Payments, the Executive shall be deemed to pay federal income taxes
at the highest marginal rate of federal income taxation in the calendar years in
which the Gross-Up Payments are to be made and state and local income taxes at
the highest marginal rate of taxation in the state and locality of the
Executive's residence on the date of termination of employment, net of the
reduction in federal income taxes that can be obtained from deduction of such
state and local taxes (calculated by assuming that any reduction under section
68 of the Internal Revenue Code in the amount of itemized deductions allowable
to the Executive applies first to reduce the amount of such state and local
income taxes that would otherwise be deductible by the Executive, and applicable
federal FICA and Medicare withholding taxes.)

     Return of Reduced Excise Tax Payment or Payment of Additional Excise Tax.
If the Excise Tax is later determined to be less than the amount taken into
account hereunder when the Executive's employment terminated, the Executive
shall repay to the Corporation -- when the amount of the reduction in Excise Tax
is finally determined -- the portion of the Gross-Up Payments attributable to
the reduction (plus that portion of the Gross-Up Payments attributable to the
Excise Tax, federal, state and local income taxes and FICA and Medicare
withholding taxes imposed on the Gross-Up Payments being repaid by the Executive
to the extent that the repayment results in a reduction in Excise Tax, FICA and
Medicare withholding taxes and/or a federal, state or local income tax
deduction).

     If the Excise Tax is later determined to be more than the amount taken into
account hereunder when the Executive's employment terminated (due, for example,
to a payment whose existence or amount cannot be determined at the time of the
Gross-Up Payments), the Corporation shall make an additional Gross-Up Payment to
the Executive for that excess (plus any interest, penalties or additions payable
by the Executive for the excess) when the amount of the excess is finally
determined.

     (c) RESPONSIBILITIES OF THE ACCOUNTING FIRM AND THE CORPORATION.
Determinations Shall Be Made by the Accounting Firm. Subject to the provisions
of Section 2(b), all determinations required to be made under this Section 2(c)
-- including whether and when a Gross-Up Payment is required, the amount of the
Gross-Up Payment and the assumptions to be used to arrive at the determination
(collectively, the "Determination") -- shall be made by the Accounting Firm,
which shall provide detailed supporting calculations both to the Corporation and
the Executive within 15 business days after receipt of notice from the
Corporation or the Executive that there has been a Gross-Up Payment, or such
earlier time as is requested by the Corporation.

     Fees and Expenses of the Accounting Firm and Agreement with the Accounting
Firm. All fees and expenses of the Accounting Firm shall be borne solely by the
Corporation. The Corporation shall enter into any agreement requested by the
Accounting Firm in connection with the performance of its services hereunder.

     Accounting Firm's Opinion. If the Accounting Firm determines that no Excise
Tax is payable by the Executive, the Accounting Firm shall furnish the Executive
with a written opinion to that effect, and to the effect that





                                       5
<PAGE>


failure to report Excise Tax, if any, on the Executive's applicable federal
income tax return will not result in the imposition of a negligence or similar
penalty.

     Accounting Firm's Determination Is Binding; Underpayment and Overpayment.
The Determination by the Accounting Firm shall be binding on the Corporation and
the Executive. Because of the uncertainty in determining whether any of the
Total Benefits will be subject to the Excise Tax at the time of the
Determination, it is possible that Gross-Up Payments that should have been made
will not have been made by the Corporation ("Underpayment"), or that Gross-Up
Payments will be made that should not have been made by the Corporation
("Overpayment"). If, after a Determination by the Accounting Firm, the Executive
is required to make a payment of additional Excise Tax, the Accounting Firm
shall determine the amount of the Underpayment that has occurred. The
Underpayment (together with interest at the rate provided in section
1274(d)(2)(B) of the Internal Revenue Code) shall be paid promptly by the
Corporation to or for the benefit of the Executive. If the amount of the
Gross-Up Payment exceeds the amount necessary to reimburse the Executive for his
Excise Tax, the Accounting Firm shall determine the amount of the Overpayment
that has been made. The Overpayment (together with interest at the rate provided
in section 1274(d)(2)(B) of the Internal Revenue Code) shall be paid promptly by
the Executive to or for the benefit of the Corporation. Provided that his
expenses are reimbursed by the Corporation, the Executive shall cooperate with
any reasonable requests by the Corporation in any contests or disputes with the
Internal Revenue Service relating to the Excise Tax.

     Accounting Firm Conflict of Interest. If the Accounting Firm is serving as
accountant or auditor for the individual, entity or group effecting the Change
in Control, the Executive may appoint another nationally recognized public
accounting firm to make the Determinations required hereunder (in which case the
term "Accounting Firm" as used in this Agreement shall be deemed to refer to the
accounting firm appointed by the Executive under this paragraph).

     (d) NO MITIGATION REQUIRED. The Corporation hereby acknowledges that it
will be difficult and could be impossible (1) for the Executive to find
reasonably comparable employment after his employment terminates, and (2) to
measure the amount of damages the Executive may suffer as a result of
termination. Additionally, the Corporation acknowledges that its general
severance pay plans do not provide for mitigation, offset, or reduction of any
severance payment received thereunder. Accordingly, the Corporation further
acknowledges that the payment of severance and termination benefits by the
Corporation under this Agreement is reasonable and will be liquidated damages,
and the Executive shall not be required to mitigate the amount of any payment
provided for in this Agreement by seeking other employment or otherwise, nor
will any profits, income, earnings, or other benefits from any source whatsoever
create any mitigation, offset, reduction, or any other obligation on the part of
the Executive hereunder or otherwise.

3.   GOOD REASON

     (a) DEFINITION OF GOOD REASON. For purposes of this Agreement, "Good
Reason" means the occurrence of any of the events or conditions described in
clauses (1) through (7) hereof without the Executive's express written consent:

     (1)  Change in Office or Position or Termination as a Director: failure to
          elect or reelect or otherwise to maintain the Executive in the office
          or position, or a substantially equivalent office or position, of or
          with the Corporation and the Bank that the Executive held immediately
          before the Change in Control, or the removal or failure to nominate
          the Executive as a director of the Corporation (or any successor
          thereto) if the Executive shall have been a director of the
          Corporation immediately before the Change in Control,

     (2)  Adverse Change in the Scope of His Duties or Compensation and
          Benefits:

          (a)  a significant adverse change in the nature or scope of the
               authorities, powers, functions, responsibilities, or duties
               associated with the Executive's position with the Corporation or
               the Bank compared to the nature or scope of the



                                       6
<PAGE>


               authorities, powers, functions, responsibilities, or duties
               associated with the position immediately before the Change in
               Control,

          (b)  a change in the Executive's reporting relationship such that the
               Executive no longer reports directly to the Corporation's board
               of directors,

          (c)  a reduction in the aggregate of the Executive's annual
               compensation received from the Corporation and the Bank, or

          (d)  the termination or denial of the Executive's rights to benefits
               under the Corporation's or the Bank's benefit, compensation, and
               incentive plans and arrangements or a reduction in the scope or
               value thereof, which situation is not remedied within 10 calendar
               days after written notice to the Corporation from the Executive,

     (3)  Adverse Change in Circumstances: the Executive determines that a
          change in circumstances has occurred after a Change in Control,
          including without limitation a change in the scope of the business or
          other activities for which the Executive is responsible compared to
          his responsibilities immediately before the Change in Control, (a)
          which renders the Executive substantially unable to carry out,
          substantially hinders the Executive's performance of, or causes the
          Executive to suffer a substantial reduction in, any of the
          authorities, powers, functions, responsibilities, or duties associated
          with the office or position held by the Executive immediately before
          the Change in Control, and (b) which situation is not remedied within
          10 calendar days after written notice to the Corporation from the
          Executive of such determination. Provided his determination is made in
          good faith, the Executive's determination will be conclusive and
          binding upon the parties hereto. The Executive's determination will be
          presumed to have been made in good faith, unless the Corporation
          establishes by clear and convincing evidence that it was not made in
          good faith,

     (4)  Liquidation and Merger of the Corporation or the Bank: the
          liquidation, dissolution, merger, consolidation or reorganization of
          the Corporation or the Bank or transfer of all or substantially all of
          the business or assets of either the Corporation or the Bank, unless
          the successor or successors (by liquidation, merger, consolidation,
          reorganization, transfer or otherwise) to which all or substantially
          all of the business or assets have been transferred (directly or by
          operation of law) assumes all duties and obligations of the
          Corporation under this Agreement,

     (5)  Relocation of the Executive: the Corporation or the Bank relocates its
          principal executive offices, or requires the Executive to have his
          principal location of work changed, to any location that is more than
          15 miles from the location thereof immediately before the Change in
          Control, or requires the Executive to travel away from his office in
          the course of discharging his responsibilities or duties hereunder at
          least 20% more (in terms of aggregate days in any calendar year or in
          any calendar quarter when annualized for purposes of comparison to any
          prior year) than was required of Executive in any of the three full
          years immediately before the Change in Control,

     (6)  Change in Administrative Support: the adverse and substantial
          alteration in the nature and quality of the office space within which
          the Executive performs his duties, including the size and location
          thereof, or a substantial reduction in the secretarial and
          administrative support provided to the Executive, or

     (7)  Breach of this Agreement: without limiting the generality or effect of
          the foregoing, any material breach of this Agreement by the
          Corporation or any successor thereto.

     (b) NO EFFECT ON EMPLOYEE BENEFITS. Termination by the Corporation under
Section 1(a)(1) or Section 1(b)(1) (termination within three years after a
Change in Control or termination on or before March 7, 2005) or termination by
the Executive under Section 1(a)(2) or Section 1(b)(2) (termination for Good
Reason) will not affect any rights the Executive may have under any benefit,
compensation, or incentive agreement, policy, plan, program, or arrangement of
the Corporation or the Bank, which rights shall be governed by the terms
thereof.

4.   TERMINATION FOR WHICH NO SEVERANCE OR TERMINATION BENEFITS ARE PAYABLE

     (a) NO SEVERANCE FOR TERMINATION FOR CAUSE. Anything in this Agreement to
the contrary notwithstanding, under no circumstance shall the Executive be
entitled to severance or termination benefits if his employment terminates for
Cause.

     (1)  Cause Means Commission of Any of the Following Acts: For purposes of
          this Agreement, "Cause" means the Executive shall have committed any
          of the following acts--

          (a)  Fraud, Embezzlement or Theft: an intentional act of fraud,
               embezzlement, or theft in connection with his duties or in the
               course of his employment with the Corporation or the Bank,

          (b)  Intentional Harm: intentional wrongful damage to property of the
               Corporation or the Bank, causing material harm to the Corporation
               or the Bank,

          (c)  Disclosure of Trade Secrets: intentional wrongful disclosure of
               secret processes or confidential information of the Corporation
               or the Bank, causing material harm to the Corporation or the
               Bank,

          (d)  Competing with the Corporation or the Bank: intentional wrongful
               engagement in any competitive activity. For purposes of this
               Agreement, competitive activity means the Executive's
               participation, without the written consent of an officer of the
               Corporation, in the management of any business enterprise if (1)
               the enterprise engages in substantial and direct competition with
               the Corporation or the Bank, (2) the enterprise's revenues
               derived from any product or service competitive with any product
               or service of the Corporation or the Bank amounted to 10% or more
               of such enterprise's revenues for its most recently completed
               fiscal year, and (3) the Corporation's revenues from the product
               or service amounted to 10% of the Corporation's revenues for its
               most recently completed fiscal year, or the Bank's revenues from
               the product or service amounted to 10% of the Bank's revenues for
               its most recently completed fiscal year. A competitive activity
               does not include mere ownership of securities in any such
               enterprise and the exercise of rights appurtenant thereto,
               provided the Executive's share ownership does not give him
               practical or legal control of the enterprise. For this purpose,
               ownership of less than 5% of the enterprise's outstanding voting
               securities shall conclusively be presumed to be insufficient for
               practical or legal control, and ownership of more than 50% shall
               conclusively be presumed to constitute practical and legal
               control.

                    If the Executive is now or hereafter becomes subject to an
               agreement not to compete with the Corporation or the Bank, a
               breach by the Executive of that other non-competition agreement
               shall be grounds for denial of severance and termination benefits
               for Cause under this clause (d) of Section 4(a)(1). But if the
               Executive engages in a competitive activity under circumstances
               justifying denial of severance or termination benefits for Cause
               under this clause (d), that shall not necessarily be grounds for
               concluding that the Executive has also breached the other
               non-competition agreement to which he is or may become



                                       8
<PAGE>


               subject. This clause (d) is not intended to and shall not be
               construed to supersede or amend any provision of an employment or
               non-competition agreement to which the Executive is or may become
               subject. This clause (d) does not grant to the Executive any
               right or privilege to engage in other activities or enterprises,
               whether in competition with the Corporation or the Bank or
               otherwise, or

          (e)  Termination for Cause under an Employment Agreement: any actions
               that have caused the Executive to be terminated for cause under
               any employment agreement existing on the date hereof or hereafter
               entered into between the Executive and the Corporation or the
               Bank.

     (2)  Definition of "Intentional": For purposes of this Agreement, no act or
          failure to act on the part of the Executive shall be deemed to have
          been intentional if it was due primarily to an error in judgment or
          negligence. An act or failure to act on the Executive's part shall be
          considered intentional if it is not in good faith and if it is without
          a reasonable belief that the action or failure to act is in the best
          interests of the Corporation.

     (3)  Termination for Cause Can Occur Solely by Formal Board Action. The
          Executive shall not be deemed to have been terminated for Cause under
          this Agreement unless and until there shall have been delivered to the
          Executive a copy of a resolution duly adopted by the affirmative vote
          of at least three-fourths (3/4) of the directors of the Corporation
          then in office at a meeting of the board of directors called and held
          for such purpose, which resolution shall (a) contain findings that, in
          the good faith opinion of the board, the Executive has committed an
          act constituting Cause and (b) specify the particulars thereof in
          detail. Notice of that meeting and the proposed termination for Cause
          shall be given to the Executive a reasonable amount of time before the
          board's meeting. The Executive and his counsel (if the Executive
          chooses to have counsel present) shall have a reasonable opportunity
          to be heard by the board at the meeting. Nothing in this Agreement
          limits the Executive's or his beneficiaries' right to contest the
          validity or propriety of the board's determination of Cause, and they
          shall have the right to contest the validity or propriety of the
          board's determination of Cause even if that right does not exist under
          any employment agreement of the Executive.

     (b) NO SEVERANCE UNDER THIS AGREEMENT FOR THE EXECUTIVE'S DEATH OR
DISABILITY. Anything in this Agreement to the contrary notwithstanding, under no
circumstance shall the Executive be entitled to severance payments or
termination benefits if --

     (1)  Death: the Executive dies while actively employed by the Corporation
          or the Bank, or

     (2)  Disability: the Executive becomes totally disabled while actively
          employed by the Corporation or the Bank. For purposes of this
          agreement, the term "totally disabled" means that because of injury or
          sickness, the Executive is unable to perform his duties.

     The benefits, if any, payable to the Executive or his beneficiary(ies) or
estate relating to his death or disability shall be determined solely by such
benefit plans or arrangements as the Corporation or the Bank may have with the
Executive relating to death or disability, not this Agreement.

5.   TERM OF AGREEMENT

     The initial term of this Agreement shall be for a period of three years,
commencing __________________, 2002. On the first anniversary of the
____________________, 2002 effective date of this Agreement, and on each
anniversary thereafter, the Agreement shall be extended for one additional year
if the Corporation's board of directors determines that the Executive's
performance has satisfied the standards and requirements of the board and that
the term




                                       9
<PAGE>


therefore shall be extended. References herein to the term of this Agreement
shall refer to the initial term, as the same may be extended. Unless sooner
terminated, this Agreement shall terminate when the Executive reaches age 65. If
the board decides not to extend the term of this Agreement, this Agreement shall
nevertheless remain in force until its term expires. The board's decision not to
extend the term of this Agreement shall not -- by itself -- give the Executive
any rights under this Agreement to claim an adverse change in his position,
compensation or circumstances or otherwise to claim entitlement to severance or
termination benefits under this Agreement.

6.   THIS AGREEMENT IS NOT AN EMPLOYMENT CONTRACT

     The parties hereto acknowledge and agree that (a) this Agreement is not a
management or employment agreement and (b) nothing in this Agreement shall give
the Executive any rights or impose any obligations to continued employment by
the Bank or Corporation or any subsidiary or successor of the Bank or
Corporation, nor shall it give the Bank or Corporation any rights or impose any
obligations for the continued performance of duties by the Executive for the
Bank or Corporation or any subsidiary or successor of the Bank or Corporation.

7.   PAYMENT OF LEGAL FEES

     (a) THE EXECUTIVE MAY ENFORCE THIS AGREEMENT THROUGH LEGAL ACTION. The
Corporation irrevocably authorizes the Executive to retain from time to time
counsel of Executive's choice to advise and represent him in the interpretation,
enforcement or defense of the parties' rights and responsibilities under this
Agreement, if after a Change in Control occurs --

     (1)  the Executive concludes that the Corporation has failed to comply with
          any of its obligations under this Agreement, or

     (2)  if the Corporation or any or any other person takes or threatens to
          take any action to declare this Agreement void or unenforceable, or
          institutes any litigation or other action or proceeding designed to
          deny, or to recover from, the Executive the benefits provided or
          intended to be provided to the Executive under this Agreement,

including without limitation the initiation or defense of any litigation or
other legal action, whether by or against the Corporation or any director,
officer, stockholder or other person affiliated with the Corporation, in any
jurisdiction.

     (b) FEES AND EXPENSES WILL BE PAID BY THE CORPORATION. The Corporation
desires that the Executive not be required to incur legal fees and the related
costs and expenses associated with the interpretation, enforcement, or defense
of Executive's rights under this Agreement by litigation or otherwise, because
the amounts thereof would substantially detract from the benefits intended to be
extended to the Executive under this Agreement. Therefore, even if the Executive
does not prevail in whole or in part in the litigation or other legal action
associated with the interpretation, enforcement or defense of Executive's rights
under this Agreement, the Corporation hereby agrees to pay and be solely
financially responsible for any and all attorneys' and related fees, costs and
expenses incurred by the Executive in the litigation or other legal action, up
to a maximum of $500,000. The fees and expenses of counsel selected by the
Executive shall be paid or reimbursed to the Executive by the Corporation on a
regular, periodic basis, upon presentation by the Executive of a statement or
statements prepared by such counsel in accordance with counsel's customary
practices. Anything herein to the contrary notwithstanding, nothing in this
Agreement authorizes the Corporation to pay or the Executive to demand payment
of fees, costs and expenses if and to the extent payment of fees, costs and
expenses constitutes a "prohibited indemnification payment" within the meaning
of Federal Deposit Insurance Corporation Rule 359.1(l)(1) [12 CFR 359.1(l)(1)].

     (c) COST OF LIVING ADJUSTMENT FOR CAP ON LEGAL FEE REIMBURSEMENT. Upon the
occurrence of a Change in Control, the $500,000 cap on legal fee reimbursement
provided by Section 7(b) will be subject to a cost of living adjustment equal to
the value of the expression A x B, in which expression:

          A = $500,000, and




                                       10
<PAGE>

          B = Cost of living adjustment or inflation factor. This is computed by
          dividing the Consumer Price Index for All Urban Consumers ("CPI-U")
          prepared by the U.S. Bureau of Labor Statistics, or any successor
          thereto, for the CPI-U for January of the year during which the Change
          in Control occurs by the CPI-U for January 2000.

The cost of living adjustment provided in this Paragraph 7(c) shall be
considered to be part of the Executive's payment of legal fees for purposes of
this Agreement.

     Illustration of Cost of Living Adjustment. To explain the cost of living
adjustment calculation for Payment of Legal Fees, we use the following example.

     First, we determine the appropriate CPI-Us. The Agreement calls for the use
of the CPI-Us for January 2000 and the January of the year during which the
Change in Control occurs. Assume a Change in Control occurs in April 2009. For
illustrative purposes only, the CPI-U for January 2000 is 156.7, and the CPI-U
for January 2009 is 213.3.

     Second, we calculate the cost of living adjustment or inflation factor. To
do this, we divide the CPI-U for January 2009 (213.3) by the CPI-U for January
2000 (156.7). Our result is 1.361 (i.e., a 36.1 percent increase).

     Finally, we calculate the raw cost of living adjustment. To do this, we
multiply the base Payment of Legal Fees amount by the inflation factor. In our
example, $500,000 multiplied by the inflation factor of 1.361 equals $680,500.

     (d) THE EXECUTIVE MAY CHOOSE THE CORPORATION'S COUNSEL. Notwithstanding any
existing or previous attorney-client relationship between the Corporation and
any counsel chosen by the Executive under Section 7(a), the Corporation
irrevocably consents to the Executive's entering into an attorney-client
relationship with that counsel, and the Corporation and the Executive agree that
a confidential relationship shall exist between the Executive and that counsel.

8.   WITHHOLDING OF TAXES

     The Corporation or the Bank may withhold from any benefits payable under
this Agreement all Federal, state, local, or other taxes as may be required by
law, governmental regulation, or ruling.

9.   SUCCESSORS AND ASSIGNS

     (a) THIS AGREEMENT IS BINDING ON THE CORPORATION'S SUCCESSORS. This
Agreement shall be binding upon the Corporation and any successor to the
Corporation, including any persons acquiring directly or indirectly all or
substantially all of the business or assets of the Corporation by purchase,
merger, consolidation, reorganization, or otherwise. Any such successor shall
thereafter be deemed to be the "Corporation" for purposes of this Agreement. But
this Agreement and the Corporation's obligations under this Agreement are not
otherwise assignable, transferable, or delegable by the Corporation. By
agreement in form and substance satisfactory to the Executive, the Corporation
shall require any successor to all or substantially all of the business or
assets of the Corporation expressly to assume and agree to perform this
Agreement in the same manner and to the same extent the Corporation would be
required to perform if no such succession had occurred.

     (b) THIS AGREEMENT IS ENFORCEABLE BY THE EXECUTIVE AND HIS HEIRS. This
Agreement will inure to the benefit of and be enforceable by the Executive's
personal or legal representatives, executors, administrators, successors, heirs,
distributes, and legatees.

     (c) THIS AGREEMENT IS PERSONAL IN NATURE AND IS NOT ASSIGNABLE. This
Agreement is personal in nature. Without written consent of the other party,
neither party shall assign, transfer, or delegate this Agreement or any rights
or obligations under this Agreement except as expressly provided in this Section
9. Without limiting the




                                       11
<PAGE>


generality or effect of the foregoing, the Executive's right to receive payments
hereunder is not assignable or transferable, whether by pledge, creation of a
security interest, or otherwise, except for a transfer by Executive's will or by
the laws of descent and distribution. If the Executive attempts an assignment or
transfer that is contrary to this Section 9, the Corporation shall have no
liability to pay any amount to the assignee or transferee.

10.  NOTICES

     All notices, requests, demands and other communications hereunder shall be

such waiver, modification or discharge is agreed to in a writing or writings
signed by the Executive and by the Corporation. No waiver by either party hereto
at any time of any breach by the other party hereto or compliance with any
condition or provision of this Agreement to be performed by such other party
will be deemed a waiver of similar or dissimilar provisions or conditions at the
same or at any prior or subsequent time. No agreements or representations, oral
