                           1998 AMENDMENT TO AGREEMENT
                           WITH NORMAN E. BENDEN, JR.



         This 1998 Amendment modifies the agreement (the "Agreement") that The
Mahoning National Bank of Youngstown restated with Norman E. Benden, Jr. (the
"Executive") on September 15, 1997 pursuant to The Mahoning National Bank of
Youngstown Executive Phantom Stock Bonus Plan (the "Plan").

         WHEREAS, the parties to the Agreement mutually desire to amend its
vesting schedule and its provision for distributing benefits upon a change in
corporate control.

         NOW, THEREFORE, pursuant to Article IX(c) of the Plan, the undersigned
agree to amend the Agreement as follows, effective immediately on execution
hereof.

         1. Article VI of the Plan shall be amended by revising, in its
entirety, Schedule "A" (which is referenced therein). The version of Schedule
"A" that was attached to the Agreement is accordingly superseded, and shall be
replaced by the version of Schedule "A" that is attached to this 1998 Amendment.

         2. Article VII(a) of the Plan shall be amended by revising the first
sentence of its second paragraph to provide as follows, with italics herein
highlighting new text:

         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank either more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date (or more than 90 days before a Change in Control,
         provided the Executive files a duly executed "Special Election of
         Payment Method after a Change in Control" in the form attached hereto
         as Schedule "B").

         3. Nothing contained herein shall be held to alter, vary or affect any
of the terms, provisions, or conditions of the Plan, other than as stated above.

                    As Restated effective September 15, 1997


         AGREEMENT made this 15th day of September, 1997 (the "Effective Date"),
restates and supersedes an agreement entered into on the 19th day of November,
1993 between The Mahoning National Bank of Youngstown (hereinafter referred to
as the "Bank"), and Mr. Norman E. Benden, Jr. (hereinafter referred to as
"Executive").

         In consideration of the mutual covenants, terms, conditions, and
agreements herein contained the parties hereby agree to enter into this
Executive Phantom Stock Bonus Plan (hereinafter sometimes referred to as the
"Plan"), as follows:

                                    ARTICLE I

                                    PURPOSES

         The purposes of this Plan are: (a) to enable the Bank to retain the
Executive in its employ; and (b) to reward the Executive for the time and effort
he expends in his job and for the success achieved.

                                   ARTICLE II

                                   DEFINITIONS

         The terms used in this Plan shall have the following meanings:

(a)      "Aggregate Phantom Stock Account Value" shall mean the sum of the
         Phantom Stock Account Value plus all distributions made to the
         Executive pursuant to Article VII, Section (c), prior to the date said
         Executive terminates his employment with the Bank.

(b)      "Change in Control" shall mean:

         30% of the Bank's or the Company's voting stock; or

         (ii) the acquisition of the ability to control the election of a
         majority of the Bank's or the Company's directors; or

         (iii) the acquisition of a controlling influence over the management or
         policies of the Bank or the Company by any person or by persons acting
         as a "group" (within the meaning of Section 13(d) of the Securities
         Exchange Act of 1934); or

<PAGE>   9


         (iv) during any period of two consecutive years, individuals (the
         "Continuing Directors") who at the beginning of such period constitute
         the Board of Directors of the Bank or the Company (the "Existing
         Board") cease for any reason to constitute at least two-thirds thereof,
         provided that any individual whose election or nomination for election
         as a member of the Existing Board was approved by a vote of at least
         two-thirds of the Continuing Directors then in office shall be
         considered a Continuing Director.

         Notwithstanding the foregoing, in the case of (i), (ii) and (iii)
         hereof, ownership or control of the Bank by the Company itself shall
         not constitute a Change in Control. For purposes of this paragraph
         only, the term "person" refers to an individual or a corporation,
         partnership, trust, association, joint venture, pool, syndicate, sole
         proprietorship, unincorporated organization or any other form of entity
         not specifically listed herein.

         Notwithstanding the foregoing, no trust department or other designated
         fiduciary or other trustee of such trust department of the Bank or a
         subsidiary of the Bank, or other similar fiduciary capacity of the Bank
         with direct voting control of the stock shall be included or
         considered. Further, no profit-sharing, employee stock ownership,
         employee stock purchase and savings, employee pension, or other
         employee benefit plan of the Bank or any of its subsidiaries, and no
         trustee of any such plan in its capacity as such trustee, shall be
         included or considered.

(c)      "Change-in-Control Account Value" shall equal the sum of (i) the Net
         Vested Account Value reasonably estimated as of the closing date of the
         Change in Control, and (ii) the present value, which shall in no event
         be less than zero, of the difference between (a) and (b) hereof,
         assuming a discount at the current long-term applicable federal rate,
         compounded monthly, for a period of 15 years.

                  (a) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to 8%.

                  (b) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to the current
                  long-term applicable federal rate (compounded monthly).

(d)      "Committee" means the members of the Executive Committee of the Board
         of Directors of the Bank who are not participants in this Plan.

(e)      "Common Stock" and/or "Shares" shall mean shares of common stock of 
         Mahoning National Bancorp, Inc.

(f)      "Election Form" shall mean the form attached hereto as Exhibit "A-1".

<PAGE>   10


(g)      "Holding Company" means Mahoning National Bancorp, Inc., which owns all
         of the issued and outstanding shares of Bank.

(h)      "Net Vested Account Value" shall mean the Vested Account Value minus
         the aggregate of all distributions to the Participant pursuant to
         Article VII, Section (c).

(i)      "Permanent Disability" shall mean a situation in which the Executive is
         permanently physically or mentally unable to perform his customary
         and/or required duties at the Bank. The determination as to whether or
         not an Executive is permanently disabled shall be made by the
         Committee, and such determination shall be conclusive. Provided,
         however, if the Executive is disabled for purposes of the Bank's
         disability insurance plan, he shall be conclusively determined to be
         disabled under this Plan.

(j)      "Phantom Stock Account Value" means the number of Phantom Shares
         credited to a Participant's account multiplied by the average fair
         market value, over the 10 business days preceding the date of any
         valuation, of the Common Stock of Mahoning National Bancorp, Inc.
         Notwithstanding the foregoing, in the event of the sale or merger of
         the Holding Company, the sale or merger price of the Common Stock shall
         determine the Executive's Phantom Stock Account Value.

(k)      "Retirement" means a severance from the employment of the Bank under
         the Bank's qualified benefit plan as constituted at present or as may
         be amended hereafter.

(l)      "Salary" and/or "Pay" shall mean the Executive's annual base
         compensation, but does not include other compensation, including, but
         not limited to hospitalization, pension benefits, etc.

(m)      "Termination Date" means the date of Executive's severance from
         employment with the Bank by reason of death, disability, retirement,
         resignation, or otherwise.

(n)      "Vested Account Value" shall equal the Aggregate Phantom Stock Account
         Value multiplied by the applicable Vesting Percentage set forth in
         Schedule A attached hereto.

(o)      "Vesting Percentage" shall mean that percentage listed on Schedule A,
         which is attached hereto, which corresponds with the age of the
         Executive, at any given time. However, advances and or changes in the
         vesting schedule with respect to a change in the age of the Executive
         shall be made only on December 31 of each calendar year during which
         Executive attained the stated age.

                                   ARTICLE III

                                 ADMINISTRATION

(a)      The complete and sole administration of this Plan is the responsibility
         of those members of the Committee who are not Participants. No member
         of the Committee shall be liable for any act done or determination made
         in good faith.

(b)      The construction and interpretation by the Committee of any provisions
         of this Plan shall be final and conclusive. The Committee shall
         determine, from time to time, subject to the provisions of this Plan,
         the Executives who shall participate in the Plan (sometimes hereinafter
         called "Participants").

(c)      The Committee may, at its discretion, delegate its duties to the
         outside auditors of the Bank, but may not delegate its authority to
         apply or interpret the provisions of this Plan or to make
         determinations specified in Section (b) of this Article III.

                                   ARTICLE IV

                     ESTABLISHMENT OF PHANTOM STOCK ACCOUNT

         The Bank shall set up an appropriate record (hereinafter called the
"Phantom Stock Account") in the name of each Executive under the Plan, and shall
record all activities of this agreement in the respective Phantom Stock Accounts
of each Executive.

                                    ARTICLE V

                        CREDITS TO ACCOUNTS OF EXECUTIVES

(a)      As of December 31st of each year that the Executive is a full-time
         employee of the Bank, the Bank shall credit a number of Phantom Shares
         of the Holding Company to the account of each Executive. The number of
         Phantom Shares to be credited each year shall be determined by dividing
         the Bank's contribution by the fair market value of the Holding
         Company's Common Stock as of the date of crediting (December 31). The
         contribution by the Bank each year shall be a percentage of the
         Executive's salary as determined by the return on equity of the Bank
         for the year pursuant to a schedule to be established by the Committee
         no later than the close of the first quarter of that year.

         The ultimate computation of the number of Phantom Shares to be credited
         each year will be determined by interpolation for performance between
         the three levels established (i.e., threshold, target, and
         distinguished), and return on equity will be calculated after projected
         expense attributable to the incentive pay out. Determination of the
         number of Phantom Shares shall be solely by the Committee and shall be
         final and binding on all parties. Provided, however, if the ROE is
         below the threshold for the year, then no crediting based on a
         percentage of pay for the year shall be made.

                                       4
<PAGE>   12


(b)      So long as this Plan remains in effect, the Bank shall credit each
         Participant's account in the special ledger throughout the term of his
         employment with the Bank. Phantom Shares equivalent to dividends
         payable in cash or property paid from time to time on issued and
         outstanding shares of Common Stock, so that the amount of each such
         credit will be equivalent to dividends which the Participant would have
         received had he been the owner of the number of shares of Common Stock
         equal to the number of Phantom Shares in his account. No such credit
         shall be made with respect to any dividend paid after a Participant's
         termination of employment or after any date of termination of this
         Plan, even though the record date is prior thereto.

(c)      In the event of any stock dividend on the Common Stock or any split-up
         or combination of shares of the Common Stock, appropriate adjustments
         shall be made by the Committee in the aggregate number of Phantom
         Shares in the account of the Participant. However, the Committee shall
         not be required to establish any fractional Phantom Shares.

(d)      On or before January 31st of each year, the Bank shall provide to each
         Executive a detail of his Phantom Share Account as of December 31 of
         the previous year. This detail shall include the number of Phantom
         Shares in the Executive's account, and the Net Vested Account Value.

                                   ARTICLE VI

                                     VESTING

         So long as the Executive remains an employee of the Bank, he shall
continue to advance in the vesting schedule attached as Schedule A. Upon the
Executive's termination of employment with the Bank, he shall be permanently
vested according to the percentage given on Schedule A on the same line as his
age on the date of his termination of employment. Provided, however, if the
Executive, while in the employ of the Bank, dies or becomes permanently
disabled, he shall become permanently 100% vested. Moreover, if a Change in
Control shall occur while the Executive remains in the employ of the Bank, the
Executive shall also become permanently 100% vested.

                                   ARTICLE VII

                              PAYMENTS OF BENEFITS

(a)      Upon termination of any Participant's employment with the Bank, there
         shall be paid to him, or in the event of his death to his beneficiary
         or beneficiaries designated under Section (b) of this Article VII, an
         amount equal to the Net Vested Account Value of such Participant,
         determined in accordance with the valuation formula set forth in
         Article II, Section (j) as of the date of termination of employment of
         such Participant. Such amounts will be reduced by any amounts required
         by law to be withheld by the Bank. Such amounts with interest at the
         rate of eight percent (8%) per annum shall be distributed in the manner
         elected by the Executive on an Election Form accepted by the 

                                       5

<PAGE>   13

         Bank. The Executive may elect (1) to begin receiving distributions from
         his account on either the first day of the second month after
         termination of service with the Bank or the first day of second month
         of the calendar year immediately after termination of service with the
         Bank and (2) to receive his benefits in either a lump-sum or in
         substantially equal monthly installments over a period up to 15 years.

         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank either more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date. In the absence of a validly completed Election Form,
         the Executive's account shall be paid in 60 substantially equal monthly
         payments beginning on the first day of the second month after
         termination of service with the Bank.

(b)      Each person shall file an Election Form with the Bank's Employee
         Benefits Plan Administrator designating one or more beneficiaries to
         whom payments otherwise due the Executive shall be made in the event of
         his death while in the employ of the Bank or after termination
         therefrom. The beneficiary or beneficiaries so designated shall be one
         or more persons or entities, including a trust or estate, other than
         his creditors, or the creditors of his estate, or an entity in which
         any of the foregoing may have an interest. The Executive shall have the
         right to change the beneficiary or beneficiaries from time to time
         whether before or after termination of employment; provided, however,
         that any change shall not become effective until an Election Form is
         received by the Employee Benefits Plan Administrator.

         If the Executive dies before receiving all amounts payable of his Net
         Vested Account Value, then the remaining balance of the Executive's
         account shall be distributed in a lump sum to the Executive's
         designated beneficiary (or estate, in the absence of a validly named or
         living beneficiary) as soon as administratively practicable following
         the Executive's death; provided that the Executive may direct on an
         Election Form that any death benefits payable pursuant to this
         Agreement shall instead be distributed over a distribution period that
         effectuates the monthly installment payments selected by the Executive
         (with payments made as though the Executive survived to collect all
         payments, and terminated service on the date of his death if payments
         had not previously begun).

(c)      At the time of the college education of a child of an Executive, an
         amount of money equal to the actual expenses associated with such
         child's education may, upon application of the Executive, be disbursed
         for such purposes by the Committee, in the Committee's sole discretion,
         from the Net Vested Account Value of the Executive's Phantom Stock
         Account.

                            RESTRICTIONS UPON FUNDING

(a)      The Bank shall have no obligation to set aside, earmark or entrust any
         fund or money with which to pay its obligations under this Agreement.
         The Executive, his beneficiaries or any successor in interest to him
         shall be and remain simply a general creditor of the Bank in the same
         manner as any other creditor having a general claim for matured and
         unpaid compensation.

(b)      Subject to subsection (d) hereof, the Bank reserves the absolute right
         in its sole discretion to either fund the obligations undertaken by
         this Agreement or to refrain from funding the same and to determine the
         extent, nature, and method of such funding. Should the Bank elect to
         fund this Agreement, in whole or in part, through the purchase of life
         insurance, mutual funds, disability policies or annuities, the Bank
         reserves the absolute right, in its sole discretion, to terminate such
         funding at any time, in whole or in part. At no time shall Executive be
         deemed to have any lien nor right, title or interest in or to any
         specific funding investment or to any assets of the Bank.

(c)      If Bank elects to invest in a life insurance, disability or annuity
         policy upon the life of Executive, then Executive shall assist the Bank
         by freely submitting to a physical exam and supplying such additional
         information necessary to obtain such insurance or annuities.

(d)      Not later than ten business days before the closing date of a Change in
         Control, the Bank shall --

         (i) deposit in a grantor trust (the "Trust") that is designed in
         accordance with Revenue Procedure 92-64 and has a trustee independent
         of the Bank and the Company an amount equal to the Change-in-Control
         Account Value, unless the Executive has previously provided a written
         release of any claims under this Agreement, and

         (ii) provide the trustee of the Trust with a written direction to hold
         said amount and any investment return thereon in a segregated account
         for the benefit of the Executive, and to follow the payment schedule to
         be provided by the Executive, based on this Agreement and the
         Executive's Election Form, as to the payment of amounts from the Trust.

         Upon the Trust's final payment of all amounts due under this Section
         (d) of Article VIII, the trustee of the Trust shall pay to the Bank the
         entire balance remaining in the segregated account maintained for the
         benefit of the Executive. The Executive shall thereafter have no
         further interest in the Trust.

                                  MISCELLANEOUS

(a)      Neither Executive, his widow nor any other beneficiary under this
         Agreement shall have any power or right to transfer, assign,
         anticipate, hypothecate, mortgage, commute, modify or otherwise
         encumber in advance any of the benefits payable hereunder, nor shall
         any of said benefits be subject to seizure for the payment of any
         debts, judgments, alimony or separate maintenance owed by the Executive
         or his beneficiary, nor be transferable by operation of law in the
         event of bankruptcy, insolvency or otherwise. In the event Executive or
         any beneficiary attempts assignment, commutation, hypothecation,
         transfer or disposal of the benefits hereunder, the Bank's liabilities
         shall forthwith cease and terminate. However, in such event, the
         Committee may, in its sole discretion, from time to time, make payments
         of amounts which would otherwise be due the Executive hereunder, to
         such Executive.

(b)      The Bank expressly agrees that it shall not merge or consolidate into
         or with another Bank or sell substantially all of its assets to another
         corporation, firm or person until such corporation, firm or person
         expressly agrees, in writing, to assume and discharge the duties and
         obligations of the Bank under this Agreement. This Agreement shall be
         binding upon the parties hereto, their successors, beneficiaries, heirs
         and personal representatives.

(c)      It is agreed by and between the parties hereto that, during the
         lifetime of the Executive, this Agreement may be amended or revoked at
         any time or times, in whole or in part, by the mutual written assent of
         the Executive and the Bank.

(d)      Whenever in this Agreement words are used in the masculine or neuter
         gender, they shall be read and construed as in the masculine, feminine
         or neuter gender, whenever they should so apply.

(e)      Nothing contained in this Agreement shall affect the right of the
         Executive to participate in or be covered by any qualified or
         non-qualified pension, profit sharing, group, bonus or other
         supplemental compensation or fringe benefit plan constituting a part of
         the Bank's existing or future compensation structure.

(f)      Headings and Subheadings in this Agreement are inserted for reference
         and convenience only and shall not be deemed a part of this Agreement.

(g)      The validity and interpretation of this Agreement shall be governed by 
         the laws of the State of Ohio.

(a)      The "Named Fiduciary and Plan Administrator" of this Plan shall be the

         Bonus Plan as established herein. He may delegate to others certain
         aspects of the management and operation responsibilities of the Plan
         including the employment of advisors and the delegation of ministerial
         duties to qualified individuals.

(b)      In the event that benefits under this Plan Agreement are not paid to
         the Executive (or to his beneficiary in the case of the Executive's
         death) and such claimants feel they are entitled to receive such
         benefits, then a written claim must be made to the Named Fiduciary and
         Plan Administrator named above within sixty (60) days from the date
         payments are refused. The Named Fiduciary and Plan Administrator and
         the Bank shall review the written claim and if the claim is denied, in
         whole or in part, they shall provide in writing within ninety (90) days
         of receipt of such claim their specific reasons for such denial,
         reference to the provisions of this Agreement upon which the denial is
         based and any additional material or information necessary to perfect
         the claim. Such written notice shall further indicate the additional
         steps to be taken by claimants for a further review of the claim denial
         if the Named Fiduciary and Plan Administrator fails to take any actions
         within the aforesaid ninety-day period.

         If claimants desire a second review, they shall notify the Named
         Fiduciary and Plan Administrator in writing within sixty (60) days of
         the first claim denial. Claimants may review the Plan Agreement or any
         documents relating thereto and submit any written issues and comments
         they may feel appropriate. In its sole discretion, the Named Fiduciary
         and Plan Administrator shall then review the second claim and provide a
         written decision within sixty (60) days of receipt of such claim. This
         decision shall likewise state the specific reasons for the decision,
         and shall include reference to specific provisions of the Plan
         Agreement upon which the decision is based.

         If claimants continue to dispute the benefit denial based upon
         completed performance of the Agreement or the meaning and effect of the
         terms and conditions thereof, then claimants may submit the dispute to
         a Board of Arbitration for final arbitration. Said Board shall consist
         of one member selected by the claimant, one member selected by the Bank
         and the third member selected by the first two members. The Board shall
         operate under any generally recognized set of arbitration rules. The
         parties hereto agree that they and their heirs, personal
         representatives, successors and assigns shall be bound by the decision
         of such Board with respect to any controversy properly submitted to it
         for determination.

             REIMBURSEMENT OF EXECUTIVE FOR ENFORCEMENT PROCEEDINGS

         In the event that any dispute arises between the Executive and the Bank
as to the terms or interpretation of this Agreement, whether instituted by
formal legal proceedings or otherwise, including any action that the Executive
takes to defend against any action taken by the Bank or the Company, the Bank
shall reimburse the Executive for all costs and expenses, including reasonable

receipt, of any costs or expenses incurred by the Executive.

         AGREEMENT, made this ____ day of ________, 19__, by and between the
undersigned executive (the "Executive") and The Mahoning National Bank of
Youngstown (the "Bank") with respect to distribution of the benefits pursuant to
The Mahoning National Bank of Youngstown Executive Phantom Stock Bonus Plan (the

         NOW THEREFORE, it is mutually agreed as follows:

         1. FORM OF PAYMENT. The Executive elects to have his account
            distributed as follows:

            ____  in one lump sum payment.

            ____  in substantially equal monthly payments over a period 
                  of _____ years (no more than 15).

         The Executive must make this election either at least one year before
terminating his service with the Bank or by October 15, 1997 in order for it to
be valid and supersede a prior election.

         2. The Executive elects to have distributions from his account begin:

            ____  on the first day of the second month immediately
                  following the date in which the Executive ceases
                  service with the Bank.

            ____  on the first day of the second month of the calendar
                  year immediately following the year in which the
                  Executive ceases service with the Bank.

         3. In the event of the Executive's death, his account shall be
            distributed:

            ____  in one lump sum payment.

            ____  in accordance with the payment schedule selected in
                  paragraph 1 hereof (with payments made as though the
                  Executive survived to collect all benefits, and as
                  though the Executive terminated service on the date
                  of his death, if payments had not already begun).

due the Executive in accordance with the terms of the Plan regarding the
elections made by the Executive herein. The Executive agrees to be bound by the

         AGREEMENT made this 15th day of September, 1997 (the "Effective Date"),
restates and supersedes an agreement entered into on the 19th day of November,
1993 between The Mahoning National Bank of Youngstown (hereinafter referred to
as the "Bank"), and Mr. Frank Hierro (hereinafter referred to as "Executive").

         In consideration of the mutual covenants, terms, conditions, and
agreements herein contained the parties hereby agree to enter into this
Executive Phantom Stock Bonus Plan (hereinafter sometimes referred to as the
"Plan"), as follows:

                                    ARTICLE I

                                    PURPOSES

         The purposes of this Plan are: (a) to enable the Bank to retain the
Executive in its employ; and (b) to reward the Executive for the time and effort
he expends in his job and for the success achieved.

                                   ARTICLE II

                                   DEFINITIONS

         The terms used in this Plan shall have the following meanings:

(a)      "Aggregate Phantom Stock Account Value" shall mean the sum of the
         Phantom Stock Account Value plus all distributions made to the
         Executive pursuant to Article VII, Section (c), prior to the date said
         Executive terminates his employment with the Bank.

(b)      "Change in Control" shall mean:

         (i) the acquisition of ownership, holding or power to vote more than
         30% of the Bank's or the Company's voting stock; or

         (ii) the acquisition of the ability to control the election of a
         majority of the Bank's or the Company's directors; or


                                       1



<PAGE>   9


         (iii) the acquisition of a controlling influence over the management or
         policies of the Bank or the Company by any person or by persons acting
         as a "group" (within the meaning of Section 13(d) of the Securities
         Exchange Act of 1934); or

         (iv) during any period of two consecutive years, individuals (the
         "Continuing Directors") who at the beginning of such period constitute
         the Board of Directors of the Bank or the Company (the "Existing
         Board") cease for any reason to constitute at least two-thirds thereof,
         provided that any individual whose election or nomination for election
         as a member of the Existing Board was approved by a vote of at least
         two-thirds of the Continuing Directors then in office shall be
         considered a Continuing Director.

         Notwithstanding the foregoing, in the case of (i), (ii) and (iii)
         hereof, ownership or control of the Bank by the Company itself shall
         not constitute a Change in Control. For purposes of this paragraph
         only, the term "person" refers to an individual or a corporation,
         partnership, trust, association, joint venture, pool, syndicate, sole
         proprietorship, unincorporated organization or any other form of entity
         not specifically listed herein.

         Notwithstanding the foregoing, no trust department or other designated
         fiduciary or other trustee of such trust department of the Bank or a
         subsidiary of the Bank, or other similar fiduciary capacity of the Bank
         with direct voting control of the stock shall be included or
         considered. Further, no profit-sharing, employee stock ownership,
         employee stock purchase and savings, employee pension, or other
         employee benefit plan of the Bank or any of its subsidiaries, and no
         trustee of any such plan in its capacity as such trustee, shall be
         included or considered.

(c)      "Change-in-Control Account Value" shall equal the sum of (i) the Net
         Vested Account Value reasonably estimated as of the closing date of the
         Change in Control, and (ii) the present value, which shall in no event
         be less than zero, of the difference between (a) and (b) hereof,
         assuming a discount at the current long-term applicable federal rate,
         compounded monthly, for a period of 15 years.

         (a)      The future value determined by assuming that the Net Vested
                  Account Value determined in accordance with clause (i) above
                  appreciates for 15 years at a rate equal to 8%.

         (b)      The future value determined by assuming that the Net Vested
                  Account Value determined in accordance with clause (i) above
                  appreciates for 15 years at a rate equal to the current
                  long-term applicable federal rate (compounded monthly).

(d)      "Committee" means the members of the Executive Committee of the Board
         of Directors of the Bank who are not participants in this Plan.

(g)      "Holding Company" means Mahoning National Bancorp, Inc., which owns all
         of the issued and outstanding shares of Bank.

(h)      "Net Vested Account Value" shall mean the Vested Account Value minus
         the aggregate of all distributions to the Participant pursuant to
         Article VII, Section (c).

(i)      "Permanent Disability" shall mean a situation in which the Executive is
         permanently physically or mentally unable to perform his customary
         and/or required duties at the Bank. The determination as to whether or
         not an Executive is permanently disabled shall be made by the
         Committee, and such determination shall be conclusive. Provided,
         however, if the Executive is disabled for purposes of the Bank's
         disability insurance plan, he shall be conclusively determined to be
         disabled under this Plan.

(j)      "Phantom Stock Account Value" means the number of Phantom Shares
         credited to a Participant's account multiplied by the average fair
         market value, over the 10 business days preceding the date of any
         valuation, of the Common Stock of Mahoning National Bancorp, Inc.
         Notwithstanding the foregoing, in the event of the sale or merger of
         the Holding Company, the sale or merger price of the Common Stock shall
         determine the Executive's Phantom Stock Account Value.

(k)      "Retirement" means a severance from the employment of the Bank under
         the Bank's qualified benefit plan as constituted at present or as may
         be amended hereafter.

         compensation, but does not include other compensation, including, but
         not limited to hospitalization, pension benefits, etc.

(m)      "Termination Date" means the date of Executive's severance from
         employment with the Bank by reason of death, disability, retirement,
         resignation, or otherwise.

(n)      "Vested Account Value" shall equal the Aggregate Phantom Stock Account
         Value multiplied by the applicable Vesting Percentage set forth in
         Schedule A attached hereto.

(o)      "Vesting Percentage" shall mean that percentage listed on Schedule A,
         which is attached hereto, which corresponds with the age of the
         Executive, at any given time. However, advances and or changes in the
         vesting schedule with respect to a change in the age of the Executive
         shall be made only on December 31 of each calendar year during which
         Executive attained the stated age.

(a)      The complete and sole administration of this Plan is the responsibility
         of those members of the Committee who are not Participants. No member
         of the Committee shall be liable for any act done or determination made
         in good faith.

(b)      The construction and interpretation by the Committee of any provisions
         of this Plan shall be final and conclusive. The Committee shall

         the Executives who shall participate in the Plan (sometimes hereinafter
         called "Participants").

(c)      The Committee may, at its discretion, delegate its duties to the
         outside auditors of the Bank, but may not delegate its authority to
         apply or interpret the provisions of this Plan or to make
         determinations specified in Section (b) of this Article III.


                                   ARTICLE IV

                     ESTABLISHMENT OF PHANTOM STOCK ACCOUNT

         The Bank shall set up an appropriate record (hereinafter called the
"Phantom Stock Account") in the name of each Executive under the Plan, and shall
record all activities of this agreement in the respective Phantom Stock Accounts
of each Executive.


                                    ARTICLE V

                        CREDITS TO ACCOUNTS OF EXECUTIVES

(a)      As of December 31st of each year that the Executive is a full-time
         employee of the Bank, the Bank shall credit a number of Phantom Shares
         of the Holding Company to the account of each Executive. The number of
         Phantom Shares to be credited each year shall be determined by dividing
         the Bank's contribution by the fair market value of the Holding
         Company's Common Stock as of the date of crediting (December 31). The
         contribution by the Bank each year shall be a percentage of the
         Executive's salary as determined by the return on equity of the Bank
         for the year pursuant to a schedule to be established by the Committee
         no later than the close of the first quarter of that year.

         The ultimate computation of the number of Phantom Shares to be credited
         each year will be determined by interpolation for performance between
         the three levels established (i.e., threshold, target, and
         distinguished), and return on equity will be calculated after projected
         expense attributable to the incentive pay out. Determination of the
         number of Phantom Shares shall be solely by the Committee and shall be
         final and binding on all parties. Provided, however, if the ROE is
         below the threshold for the year, then no crediting based on a
         percentage of pay for the year shall be made.

(b)      So long as this Plan remains in effect, the Bank shall credit each
         Participant's  account in the special ledger throughout the term of his
         employment with the Bank. Phantom Shares equivalent to dividends
         payable in cash or property paid from time to time on issued and
         outstanding shares of Common Stock, so that the amount of each such
         credit will be equivalent to dividends which the Participant would have
         received had he been the owner of the number of shares of Common Stock
         equal to the number of Phantom Shares in his account. No such credit
         shall be made with respect to any dividend paid after a Participant's
         termination of employment or after any date of termination of this
         Plan, even though the record date is prior thereto.

(c)      In the event of any stock dividend on the Common Stock or any split-up
         or combination of shares of the Common Stock, appropriate adjustments
         shall be made by the Committee in the aggregate number of Phantom
         Shares in the account of the Participant. However, the Committee shall
         not be required to establish any fractional Phantom Shares.

(d)      On or before January 31st of each year, the Bank shall provide to each
         Executive a detail of his Phantom Share Account as of December 31 of
         the previous year. This detail shall include the number of Phantom
         Shares in the Executive's account, and the Net Vested Account Value.

                                   ARTICLE VI

                                     VESTING

         So long as the Executive remains an employee of the Bank, he shall
continue to advance in the vesting schedule attached as Schedule A. Upon the
Executive's termination of employment with the Bank, he shall be permanently
vested according to the percentage given on Schedule A on the same line as his
age on the date of his termination of employment. Provided, however, if the
Executive, while in the employ of the Bank, dies or becomes permanently
disabled, he shall become permanently 100% vested. Moreover, if a Change in
Control shall occur while the Executive remains in the employ of the Bank, the
Executive shall also become permanently 100% vested.

                                   ARTICLE VII

                              PAYMENTS OF BENEFITS

(a)      Upon termination of any Participant's employment with the Bank, there
         shall be paid to him, or in the event of his death to his beneficiary
         or beneficiaries designated under Section (b) of this Article VII, an
         amount equal to the Net Vested Account Value of such Participant,
         determined in accordance with the valuation formula set forth in
         Article II, Section (j) as of the date of termination of employment of
         such Participant. Such amounts will be reduced by any amounts required
         by law to be withheld by the Bank. Such amounts with interest at the
         rate of eight percent (8%) per annum shall be distributed in the manner
         elected by the Executive on an Election Form accepted by the


                                       5

<PAGE>   13


         Bank. The Executive may elect (1) to begin receiving distributions from
         his account on EITHER the first day of the second month after
         termination of service with the Bank or the first day of second month
         of the calendar year immediately after termination of service with the
         Bank and (2) to receive his benefits in either a lump-sum or in
         substantially equal monthly installments over a period up to 15 years.

         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank EITHER more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date. In the absence of a validly completed Election Form,
         the Executive's account shall be paid in 60 substantially equal monthly
         payments beginning on the first day of the second month after
         termination of service with the Bank.

         (b)      Each person shall file an Election Form with the Bank's
                  Employee Benefits Plan Administrator designating one or more
                  beneficiaries to whom payments otherwise due the Executive
                  shall be made in the event of his death while in the employ of
                  the Bank or after termination therefrom. The beneficiary or
                  beneficiaries so designated shall be one or more persons or
                  entities, including a trust or estate, other than his
                  creditors, or the creditors of his estate, or an entity in
                  which any of the foregoing may have an interest. The Executive
                  shall have the right to change the beneficiary or
                  beneficiaries from time to time whether before or after
                  termination of employment; provided, however, that any change
                  shall not become effective until an Election Form is received
                  by the Employee Benefits Plan Administrator.

                  If the Executive dies before receiving all amounts payable of
                  his Net Vested Account Value, then the remaining balance of
                  the Executive's account shall be distributed in a lump sum to
                  the Executive's designated beneficiary (or estate, in the
                  absence of a validly named or living beneficiary) as soon as
                  administratively practicable following the Executive's death;
                  provided that the Executive may direct on an Election Form
                  that any death benefits payable pursuant to this Agreement
                  shall instead be distributed over a distribution period that
                  effectuates the monthly installment payments selected by the
                  Executive (with payments made as though the Executive survived
                  to collect all payments, and terminated service on the date of
                  his death if payments had not previously begun).

         (c)      At the time of the college education of a child of an
                  Executive, an amount of money equal to the actual expenses
                  associated with such child's education may, upon application
                  of the Executive, be disbursed for such purposes by the
                  Committee, in the Committee's sole discretion, from the Net
                  Vested Account Value of the Executive's Phantom Stock Account.

                                  ARTICLE VIII

                            RESTRICTIONS UPON FUNDING

(a)      The Bank shall have no obligation to set aside, earmark or entrust any
         fund or money with which to pay its obligations under this Agreement.
         The Executive, his beneficiaries or any successor in interest to him
         shall be and remain simply a general creditor of the Bank in the same
         manner as any other creditor having a general claim for matured and
         unpaid compensation.

(b)      Subject to subsection (d) hereof, the Bank reserves the absolute right
         in its sole discretion to either fund the obligations undertaken by
         this Agreement or to refrain from funding the same and to determine the
         extent, nature, and method of such funding. Should the Bank elect to
         fund this Agreement, in whole or in part, through the purchase of life
         insurance, mutual funds, disability policies or annuities, the Bank
         reserves the absolute right, in its sole discretion, to terminate such
         funding at any time, in whole or in part. At no time shall Executive be
         deemed to have any lien nor right, title or interest in or to any
         specific funding investment or to any assets of the Bank.

(c)      If Bank elects to invest in a life insurance, disability or annuity
         policy upon the life of Executive, then Executive shall assist the Bank
         by freely submitting to a physical exam and supplying such additional
         information necessary to obtain such insurance or annuities.

(d)      Not later than ten business days before the closing date of a Change in
         Control, the Bank shall --

         (i)      deposit in a grantor trust (the "Trust") that is designed in
                  accordance with Revenue Procedure 92-64 and has a trustee
                  independent of the Bank and the Company an amount equal to the
                  Change-in-Control Account Value, unless the Executive has
                  previously provided a written release of any claims under this
                  Agreement, and

         (ii)     provide the trustee of the Trust with a written direction to
                  hold said amount and any investment return thereon in a
                  segregated account for the benefit of the Executive, and to
                  follow the payment schedule to be provided by the Executive,
                  based on this Agreement and the Executive's Election Form, as
                  to the payment of amounts from the Trust.

         Upon the Trust's final payment of all amounts due under this Section
         (d) of Article VIII, the trustee of the Trust shall pay to the Bank the
         entire balance remaining in the segregated account maintained for the
         benefit of the Executive. The Executive shall thereafter have no
         further interest in the Trust.

                                   ARTICLE IX

                                  MISCELLANEOUS

(a)      Neither Executive, his widow nor any other beneficiary under this
         Agreement shall have any power or right to transfer, assign,
         anticipate, hypothecate, mortgage, commute, modify or otherwise
         encumber in advance any of the benefits payable hereunder, nor shall
         any of said benefits be subject to seizure for the payment of any
         debts, judgments, alimony or separate maintenance owed by the Executive
         or his beneficiary, nor be transferable by operation of law in the
         event of bankruptcy, insolvency or otherwise. In the event Executive or
         any beneficiary attempts assignment, commutation, hypothecation,
         transfer or disposal of the benefits hereunder, the Bank's liabilities
         shall forthwith cease and terminate. However, in such event, the
         Committee may, in its sole discretion, from time to time, make payments
         of amounts which would otherwise be due the Executive hereunder, to
         such Executive.

(b)      The Bank expressly agrees that it shall not merge or consolidate into
         or with another Bank or sell substantially all of its assets to another
         corporation, firm or person until such corporation, firm or person
         expressly agrees, in writing, to assume and discharge the duties and
         obligations of the Bank under this Agreement. This Agreement shall be
         binding upon the parties hereto, their successors, beneficiaries, heirs
         and personal representatives.

(c)      It is agreed by and between the parties hereto that, during the
         lifetime of the Executive, this Agreement may be amended or revoked at
         any time or times, in whole or in part, by the mutual written assent of
         the Executive and the Bank.

(d)      Whenever in this Agreement words are used in the masculine or neuter
         gender, they shall be read and construed as in the masculine, feminine
         or neuter gender, whenever they should so apply.

(e)      Nothing contained in this Agreement shall affect the right of the
         Executive to participate in or be covered by any qualified or
         non-qualified pension, profit sharing, group, bonus or other
         supplemental compensation or fringe benefit plan constituting a part of
         the Bank's existing or future compensation structure.

(f)      Headings and Subheadings in this Agreement are inserted for reference
         and convenience only and shall not be deemed a part of this Agreement.

(g)      The validity and interpretation of this Agreement shall be governed by
         the laws of the State of Ohio.

                                ERISA PROVISIONS

(a)      The "Named Fiduciary and Plan Administrator" of this Plan shall be the
         Bank's Employee Benefits Plan Administrator until his resignation or
         removal by the Committee. As named Fiduciary and Administrator, the
         Employee Benefits Plan Administrator shall be responsible for the
         management, control and administration of the Executive Phantom Stock
         Bonus Plan as established herein. He may delegate to others certain
         aspects of the management and operation responsibilities of the Plan
         including the employment of advisors and the delegation of ministerial
         duties to qualified individuals.

(b)      In the event that benefits under this Plan Agreement are not paid to
         the Executive (or to his beneficiary in the case of the Executive's
         death) and such claimants feel they are entitled to receive such
         benefits, then a written claim must be made to the Named Fiduciary and
         Plan Administrator named above within sixty (60) days from the date
         payments are refused. The Named Fiduciary and Plan Administrator and
         the Bank shall review the written claim and if the claim is denied, in
         whole or in part, they shall provide in writing within ninety (90) days
         of receipt of such claim their specific reasons for such denial,
         reference to the provisions of this Agreement upon which the denial is
         based and any additional material or information necessary to perfect
         the claim. Such written notice shall further indicate the additional
         steps to be taken by claimants for a further review of the claim denial
         if the Named Fiduciary and Plan Administrator fails to take any actions
         within the aforesaid ninety-day period.

         If claimants desire a second review, they shall notify the Named
         Fiduciary and Plan Administrator in writing within sixty (60) days of
         the first claim denial. Claimants may review the Plan Agreement or any
         documents relating thereto and submit any written issues and comments
         they may feel appropriate. In its sole discretion, the Named Fiduciary
         and Plan Administrator shall then review the second claim and provide a
         written decision within sixty (60) days of receipt of such claim. This
         decision shall likewise state the specific reasons for the decision,
         and shall include reference to specific provisions of the Plan
         Agreement upon which the decision is based.

         If claimants continue to dispute the benefit denial based upon
         completed performance of the Agreement or the meaning and effect of the
         terms and conditions thereof, then claimants may submit the dispute to
         a Board of Arbitration for final arbitration. Said Board shall consist
         of one member selected by the claimant, one member selected by the Bank
         and the third member selected by the first two members. The Board shall
         operate under any generally recognized set of arbitration rules. The
         parties hereto agree that they and their heirs, personal
         representatives, successors and assigns shall be bound by the decision
         of such Board with respect to any controversy properly submitted to it
         for determination.

             REIMBURSEMENT OF EXECUTIVE FOR ENFORCEMENT PROCEEDINGS

         In the event that any dispute arises between the Executive and the Bank
as to the terms or interpretation of this Agreement, whether instituted by
formal legal proceedings or otherwise, including any action that the Executive
takes to defend against any action taken by the Bank or the Company, the Bank
shall reimburse the Executive for all costs and expenses, including reasonable
attorneys' fees, arising from such dispute, proceedings or actions, provided
that the Executive obtains either a written settlement or a final judgement by a
court of competent jurisdiction substantially in his favor. Such reimbursement
shall be paid within ten days of Executive's furnishing to the Bank written
evidence, which may be in the form, among other things, of a canceled check or
receipt, of any costs or expenses incurred by the Executive.

                       EXECUTIVE PHANTOM STOCK BONUS PLAN



                    As Restated effective September 15, 1997


         AGREEMENT made this 15th day of September, 1997 (the "Effective Date"),
restates and supersedes an agreement entered into on the 19th day of November,
1993 between The Mahoning National Bank of Youngstown (hereinafter referred to
as the "Bank"), and Mr. Gregory L. Ridler (hereinafter referred to as
"Executive").

         In consideration of the mutual covenants, terms, conditions, and
agreements herein contained the parties hereby agree to enter into this
Executive Phantom Stock Bonus Plan (hereinafter sometimes referred to as the
"Plan"), as follows:

                                    ARTICLE I

                                    PURPOSES

         The purposes of this Plan are: (a) to enable the Bank to retain the
Executive in its employ; and (b) to reward the Executive for the time and effort
he expends in his job and for the success achieved.

                                   ARTICLE II

                                   DEFINITIONS

         The terms used in this Plan shall have the following meanings:

(a)      "Aggregate Phantom Stock Account Value" shall mean the sum of the
         Phantom Stock Account Value plus all distributions made to the
         Executive pursuant to Article VII, Section (c), prior to the date said
         Executive terminates his employment with the Bank.

(b)      "Change in Control" shall mean:

         (i) the acquisition of ownership, holding or power to vote more than
         30% of the Bank's or the Company's voting stock; or

         (ii) the acquisition of the ability to control the election of a
         majority of the Bank's or the Company's directors; or


                                       1


<PAGE>   8


         (iii) the acquisition of a controlling influence over the management or
         policies of the Bank or the Company by any person or by persons acting
         as a "group" (within the meaning of Section 13(d) of the Securities
         Exchange Act of 1934); or

         (iv) during any period of two consecutive years, individuals (the
         "Continuing Directors") who at the beginning of such period constitute
         the Board of Directors of the Bank or the Company (the "Existing
         Board") cease for any reason to constitute at least two-thirds thereof,
         provided that any individual whose election or nomination for election
         as a member of the Existing Board was approved by a vote of at least
         two-thirds of the Continuing Directors then in office shall be
         considered a Continuing Director.

         Notwithstanding the foregoing, in the case of (i), (ii) and (iii)
         hereof, ownership or control of the Bank by the Company itself shall
         not constitute a Change in Control. For purposes of this paragraph
         only, the term "person" refers to an individual or a corporation,
         partnership, trust, association, joint venture, pool, syndicate, sole
         proprietorship, unincorporated organization or any other form of entity
         not specifically listed herein.

         Notwithstanding the foregoing, no trust department or other designated
         fiduciary or other trustee of such trust department of the Bank or a
         subsidiary of the Bank, or other similar fiduciary capacity of the Bank
         with direct voting control of the stock shall be included or
         considered. Further, no profit-sharing, employee stock ownership,
         employee stock purchase and savings, employee pension, or other
         employee benefit plan of the Bank or any of its subsidiaries, and no
         trustee of any such plan in its capacity as such trustee, shall be
         included or considered.

(c)      "Change-in-Control Account Value" shall equal the sum of (i) the Net
         Vested Account Value reasonably estimated as of the closing date of the
         Change in Control, and (ii) the present value, which shall in no event
         be less than zero, of the difference between (a) and (b) hereof,
         assuming a discount at the current long-term applicable federal rate,
         compounded monthly, for a period of 15 years.

                  (a) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to 8%.

                  (b) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to the current
                  long-term applicable federal rate (compounded monthly).

(d)      "Committee" means the members of the Executive Committee of the Board
         of Directors of the Bank who are not participants in this Plan.


                                       2

(e)      "Common Stock" and/or "Shares" shall mean shares of common stock of
         Mahoning National Bancorp, Inc..

(f)      "Election Form" shall mean the form attached hereto as Exhibit "A-1".

(g)      "Holding Company" means Mahoning National Bancorp, Inc., which owns all
         of the issued and outstanding shares of Bank.

(h)      "Net Vested Account Value" shall mean the Vested Account Value minus
         the aggregate of all distributions to the Participant pursuant to
         Article VII, Section (c).

(i)      "Permanent Disability" shall mean a situation in which the Executive is
         permanently physically or mentally unable to perform his customary
         and/or required duties at the Bank. The determination as to whether or
         not an Executive is permanently disabled shall be made by the
         Committee, and such determination shall be conclusive. Provided,
         however, if the Executive is disabled for purposes of the Bank's
         disability insurance plan, he shall be conclusively determined to be
         disabled under this Plan.

(j)      "Phantom Stock Account Value" means the number of Phantom Shares
         credited to a Participant's account multiplied by the average fair
         market value, over the 10 business days preceding the date of any
         valuation, of the Common Stock of Mahoning National Bancorp, Inc.
         Notwithstanding the foregoing, in the event of the sale or merger of
         the Holding Company, the sale or merger price of the Common Stock shall
         determine the Executive's Phantom Stock Account Value.

(k)      "Retirement" means a severance from the employment of the Bank under
         the Bank's qualified benefit plan as constituted at present or as may
         be amended hereafter.

(l)      "Salary" and/or "Pay" shall mean the Executive's annual base
         compensation, but does not include other compensation, including, but
         not limited to hospitalization, pension benefits, etc.

(m)      "Termination Date" means the date of Executive's severance from
         employment with the Bank by reason of death, disability, retirement,
         resignation, or otherwise.

(n)      "Vested Account Value" shall equal the Aggregate Phantom Stock Account
         Value multiplied by the applicable Vesting Percentage set forth in
         Schedule A attached hereto.

(o)      "Vesting Percentage" shall mean that percentage listed on Schedule A,
         which is attached hereto, which corresponds with the age of the
         Executive, at any given time. However, advances and or changes in the
         vesting schedule with respect to a change in the age of the Executive
         shall be made only on December 31 of each calendar year during which
         Executive attained the stated age.

                                   ARTICLE III

                                 ADMINISTRATION

(a)      The complete and sole administration of this Plan is the responsibility
         of those members of the Committee who are not Participants. No member
         of the Committee shall be liable for any act done or determination made
         in good faith.

(b)      The construction and interpretation by the Committee of any provisions
         of this Plan shall be final and conclusive. The Committee shall
         determine, from time to time, subject to the provisions of this Plan,
         the Executives who shall participate in the Plan (sometimes hereinafter
         called "Participants").

(c)      The Committee may, at its discretion, delegate its duties to the
         outside auditors of the Bank, but may not delegate its authority to
         apply or interpret the provisions of this Plan or to make
         determinations specified in Section (b) of this Article III.

                                   ARTICLE IV

                     ESTABLISHMENT OF PHANTOM STOCK ACCOUNT

         The Bank shall set up an appropriate record (hereinafter called the
"Phantom Stock Account") in the name of each Executive under the Plan, and shall
record all activities of this agreement in the respective Phantom Stock Accounts
of each Executive.

                                    ARTICLE V

                        CREDITS TO ACCOUNTS OF EXECUTIVES

(a)      As of December 31st of each year that the Executive is a full-time
         employee of the Bank, the Bank shall credit a number of Phantom Shares
         of the Holding Company to the account of each Executive. The number of
         Phantom Shares to be credited each year shall be determined by dividing
         the Bank's contribution by the fair market value of the Holding
         Company's Common Stock as of the date of crediting (December 31). The
         contribution by the Bank each year shall be a percentage of the
         Executive's salary as determined by the return on equity of the Bank
         for the year pursuant to a schedule to be established by the Committee
         no later than the close of the first quarter of that year.

         The ultimate computation of the number of Phantom Shares to be credited
         each year will be determined by interpolation for performance between
         the three levels established (i.e., threshold, target, and
         distinguished), and return on equity will be calculated after projected
         expense attributable to the incentive pay out. Determination of the
         number of Phantom Shares shall be solely by the Committee and shall be
         final and binding on all parties. Provided, however, if the ROE is
         below the threshold for the year, then no crediting based on a
         percentage of pay for the year shall be made.

(b)      So long as this Plan remains in effect, the Bank shall credit each
         Participant's account in the special ledger throughout the term of his
         employment with the Bank. Phantom Shares equivalent to dividends
         payable in cash or property paid from time to time on issued and
         outstanding shares of Common Stock, so that the amount of each such
         credit will be equivalent to dividends which the Participant would have
         received had he been the owner of the number of shares of Common Stock
         equal to the number of Phantom Shares in his account. No such credit
         shall be made with respect to any dividend paid after a Participant's
         termination of employment or after any date of termination of this
         Plan, even though the record date is prior thereto.

(c)      In the event of any stock dividend on the Common Stock or any split-up
         or combination of shares of the Common Stock, appropriate adjustments
         shall be made by the Committee in the aggregate number of Phantom
         Shares in the account of the Participant. However, the Committee shall
         not be required to establish any fractional Phantom Shares.

(d)      On or before January 31st of each year, the Bank shall provide to each
         Executive a detail of his Phantom Share Account as of December 31 of
         the previous year. This detail shall include the number of Phantom
         Shares in the Executive's account, and the Net Vested Account Value.

                                   ARTICLE VI

                                     VESTING

         The Executive shall be permanently 100% vested as exhibited in Schedule
         A.

                                   ARTICLE VII

                              PAYMENTS OF BENEFITS

(a)      Upon termination of any Participant's employment with the Bank, there
         shall be paid to him, or in the event of his death to his beneficiary
         or beneficiaries designated under Section (b) of this Article VII, an
         amount equal to the Net Vested Account Value of such Participant,
         determined in accordance with the valuation formula set forth in
         Article II, Section (j) as of the date of termination of employment of
         such Participant. Such amounts will be reduced by any amounts required
         by law to be withheld by the Bank. Such amounts with interest at the
         rate of eight percent (8%) per annum shall be distributed in the manner
         elected by the Executive on an Election Form accepted by the Bank. The
         Executive may elect (1) to begin receiving distributions from his
         account on either the first day of the second month after termination
         of service with the Bank or the first day of second month of the
         calendar year immediately after termination of service with the Bank
         and (2) to receive his benefits in either a lump-sum or in
         substantially equal monthly installments over a period up to 15 years.


                                       5


<PAGE>   12


         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank either more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date. In the absence of a validly completed Election Form,
         the Executive's account shall be paid in 60 substantially equal monthly
         payments beginning on the first day of the second month after
         termination of service with the Bank.

(b)      Each person shall file an Election Form with the Bank's Employee
         Benefits Plan Administrator designating one or more beneficiaries to
         whom payments otherwise due the Executive shall be made in the event of
         his death while in the employ of the Bank or after termination
         therefrom. The beneficiary or beneficiaries so designated shall be one
         or more persons or entities, including a trust or estate, other than
         his creditors, or the creditors of his estate, or an entity in which
         any of the foregoing may have an interest. The Executive shall have the
         right to change the beneficiary or beneficiaries from time to time
         whether before or after termination of employment; provided, however,
         that any change shall not become effective until an Election Form is
         received by the Employee Benefits Plan Administrator.

         If the Executive dies before receiving all amounts payable of his Net
         Vested Account Value, then the remaining balance of the Executive's
         account shall be distributed in a lump sum to the Executive's
         designated beneficiary (or estate, in the absence of a validly named or
         living beneficiary) as soon as administratively practicable following
         the Executive's death; provided that the Executive may direct on an
         Election Form that any death benefits payable pursuant to this
         Agreement shall instead be distributed over a distribution period that
         effectuates the monthly installment payments selected by the Executive
         (with payments made as though the Executive survived to collect all
         payments, and terminated service on the date of his death if payments
         had not previously begun).

(c)      At the time of the college education of a child of an Executive, an
         amount of money equal to the actual expenses associated with such
         child's education may, upon application of the Executive, be disbursed
         for such purposes by the Committee, in the Committee's sole discretion,
         from the Net Vested Account Value of the Executive's Phantom Stock
         Account.

                                  ARTICLE VIII

                            RESTRICTIONS UPON FUNDING

(a)      The Bank shall have no obligation to set aside, earmark or entrust any
         fund or money with which to pay its obligations under this Agreement.
         The Executive, his beneficiaries or any successor in interest to him
         shall be and remain simply a general creditor of the Bank in the same
         manner as any other creditor having a general claim for matured and
         unpaid compensation.

(b)      Subject to subsection (d) hereof, the Bank reserves the absolute right
         in its sole discretion to either fund the obligations undertaken by
         this Agreement or to refrain from funding the same and to determine the
         extent, nature, and method of such funding. Should the Bank elect to
         fund this Agreement, in whole or in part, through the purchase of life
         insurance, mutual funds, disability policies or annuities, the Bank
         reserves the absolute right, in its sole discretion, to terminate such
         funding at any time, in whole or in part. At no time shall Executive be
         deemed to have any lien nor right, title or interest in or to any
         specific funding investment or to any assets of the Bank.

(c)      If Bank elects to invest in a life insurance, disability or annuity
         policy upon the life of Executive, then Executive shall assist the Bank
         by freely submitting to a physical exam and supplying such additional
         information necessary to obtain such insurance or annuities.

(d)      Not later than ten business days before the closing date of a Change in
         Control, the Bank shall --

         (i)      Deposit in a grantor trust (the "Trust") that is designed in
                  accordance with Revenue Procedure 92-64 and has a trustee
                  independent of the Bank and the Company an amount equal to the
                  Change-in-Control Account Value, unless the Executive has
                  previously provided a written release of any claims under this
                  Agreement, and

         (ii)     provide the trustee of the Trust with a written direction to
                  hold said amount and any investment return thereon in a
                  segregated account for the benefit of the Executive, and to
                  follow the payment schedule to be provided by the Executive,
                  based on this Agreement and the Executive's Election Form, as
                  to the payment of amounts from the Trust.

         Upon the Trust's final payment of all amounts due under this Section
         (d) of Article VIII, the trustee of the Trust shall pay to the Bank the
         entire balance remaining in the segregated account maintained for the
         benefit of the Executive. The Executive shall thereafter have no
         further interest in the Trust.

                                   ARTICLE IX

                                  MISCELLANEOUS

(a)      Neither Executive, his widow nor any other beneficiary under this
         Agreement shall have any power or right to transfer, assign,
         anticipate, hypothecate, mortgage, commute, modify or otherwise
         encumber in advance any of the benefits payable hereunder, nor shall
         any of said benefits be subject to seizure for the payment of any
         debts, judgments, alimony or separate maintenance owed by the Executive
         or his beneficiary, nor be transferable by operation of law in the
         event of bankruptcy, insolvency or otherwise. In the event Executive or
         any beneficiary attempts assignment, commutation, hypothecation,
         transfer or disposal of the benefits hereunder, the Bank's liabilities
         shall forthwith cease and terminate. However, in such event, the
         Committee may, in its sole discretion, from time to time, make payments
         of amounts which would otherwise be due the Executive hereunder, to
         such Executive.

(b)      The Bank expressly agrees that it shall not merge or consolidate into
         or with another Bank or sell substantially all of its assets to another
         corporation, firm or person until such corporation, firm or person
         expressly agrees, in writing, to assume and discharge the duties and
         obligations of the Bank under this Agreement. This Agreement shall be
         binding upon the parties hereto, their successors, beneficiaries, heirs
         and personal representatives.

(c)      It is agreed by and between the parties hereto that, during the
         lifetime of the Executive, this Agreement may be amended or revoked at
         any time or times, in whole or in part, by the mutual written assent of
         the Executive and the Bank.

(d)      Whenever in this Agreement words are used in the masculine or neuter
         gender, they shall be read and construed as in the masculine, feminine
         or neuter gender, whenever they should so apply.

(e)      Nothing contained in this Agreement shall affect the right of the
         Executive to participate in or be covered by any qualified or
         non-qualified pension, profit sharing, group, bonus or other
         supplemental compensation or fringe benefit plan constituting a part of
         the Bank's existing or future compensation structure.

(f)      Headings and Subheadings in this Agreement are inserted for reference
         and convenience only and shall not be deemed a part of this Agreement.

                                ERISA PROVISIONS

(a)      The "Named Fiduciary and Plan Administrator" of this Plan shall be the
         Bank's Employee Benefits Plan Administrator until his resignation or
         removal by the Committee. As named Fiduciary and Administrator, the
         Employee Benefits Plan Administrator shall be responsible for the
         management, control and administration of the Executive Phantom Stock
         Bonus Plan as established herein. He may delegate to others certain
         aspects of the management and operation responsibilities of the Plan
         including the employment of advisors and the delegation of ministerial
         duties to qualified individuals.

(b)      In the event that benefits under this Plan Agreement are not paid to
         the Executive (or to his beneficiary in the case of the Executive's
         death) and such claimants feel they are entitled to receive such
         benefits, then a written claim must be made to the Named Fiduciary and
         Plan Administrator named above within sixty (60) days from the date
         payments are refused. The Named Fiduciary and Plan Administrator and
         the Bank shall review the written claim and if the claim is denied, in
         whole or in part, they shall provide in writing within ninety (90) days
         of receipt of such claim their specific reasons for such denial,
         reference to the provisions of this Agreement upon which the denial is
         based and any additional material or information necessary to perfect
         the claim. Such written notice shall further indicate the additional
         steps to be taken by claimants for a further review of the claim denial
         if the Named Fiduciary and Plan Administrator fails to take any actions
         within the aforesaid ninety-day period.

         If claimants desire a second review, they shall notify the Named
         Fiduciary and Plan Administrator in writing within sixty (60) days of
         the first claim denial. Claimants may review the Plan Agreement or any
         documents relating thereto and submit any written issues and comments
         they may feel appropriate. In its sole discretion, the Named Fiduciary
         and Plan Administrator shall then review the second claim and provide a
         written decision within sixty (60) days of receipt of such claim. This
         decision shall likewise state the specific reasons for the decision,
         and shall include reference to specific provisions of the Plan
         Agreement upon which the decision is based.

         If claimants continue to dispute the benefit denial based upon
         completed performance of the Agreement or the meaning and effect of the
         terms and conditions thereof, then claimants may submit the dispute to
         a Board of Arbitration for final arbitration. Said Board shall consist
         of one member selected by the claimant, one member selected by the Bank
         and the third member selected by the first two members. The Board shall
         operate under any generally recognized set of arbitration rules. The
         parties hereto agree that they and their heirs, personal
         representatives, successors and assigns shall be bound by the decision
         of such Board with respect to any controversy properly submitted to it
         for determination.

             REIMBURSEMENT OF EXECUTIVE FOR ENFORCEMENT PROCEEDINGS

         In the event that any dispute arises between the Executive and the Bank
as to the terms or interpretation of this Agreement, whether instituted by
formal legal proceedings or otherwise, including any action that the Executive
takes to defend against any action taken by the Bank or the Company, the Bank
shall reimburse the Executive for all costs and expenses, including reasonable
attorneys' fees, arising from such dispute, proceedings or actions, provided
that the Executive obtains either a written settlement or a final judgement by a
court of competent jurisdiction substantially in his favor. Such reimbursement
shall be paid within ten days of Executive's furnishing to the Bank written
evidence, which may be in the form, among other things, of a canceled check or
receipt, of any costs or expenses incurred by the Executive.

         AGREEMENT, made this ____ day of ________, 19__, by and between the
undersigned executive (the "Executive") and The Mahoning National Bank of
Youngstown (the "Bank") with respect to distribution of the benefits pursuant to
The Mahoning National Bank of Youngstown Executive Phantom Stock Bonus Plan (the

         NOW THEREFORE, it is mutually agreed as follows:

         1. FORM OF PAYMENT. The Executive elects to have his account
            distributed as follows:

            [      ]  in one lump sum payment.

            [      ]  in substantially equal monthly payments over a period of
                      _____ years (no more than 15).

         The Executive must make this election EITHER at least one year before
terminating his service with the Bank OR by October 15, 1997 in order for it to
be valid and supersede a prior election.

         2. The Executive elects to have distributions from his account begin:

            [      ]  on the first day of the second month immediately 
                      following the date in which the Executive ceases service
                      with the Bank.

            [      ]  on the first day of the second month of the calendar year
                      immediately following the year in which the Executive
                      ceases service with the Bank.

         3. In the event of the Executive's death, his account shall be
            distributed:

            [      ]  in one lump sum payment.

            [      ]  in accordance with the payment schedule selected in
                      paragraph 1 hereof (with payments made as though the
                      Executive survived to collect all benefits, and as though
                      the Executive terminated service on the date of his death,
                      if payments had not already begun).

                            WITH DAVID E. WESTERBURG



         This 1998 Amendment modifies the agreement (the "Agreement") that The
Mahoning National Bank of Youngstown restated with David E. Westerburg (the
"Executive") on September 15, 1997 pursuant to The Mahoning National Bank of
Youngstown Executive Phantom Stock Bonus Plan (the "Plan").

         WHEREAS, the parties to the Agreement mutually desire to amend its
vesting schedule and its provision for distributing benefits upon a change in
corporate control.

         NOW, THEREFORE, pursuant to Article IX(c) of the Plan, the undersigned
agree to amend the Agreement as follows, effective immediately on execution
hereof.

         1. Article VI of the Plan shall be amended by revising, in its
entirety, Schedule "A" (which is referenced therein). The version of Schedule
"A" that was attached to the Agreement is accordingly superseded, and shall be
replaced by the version of Schedule "A" that is attached to this 1998 Amendment.

         2. Article VII(a) of the Plan shall be amended by revising the first
sentence of its second paragraph to provide as follows, with italics herein
highlighting new text:

         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank either more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date (or more than 90 days before a Change in Control,
         provided the Executive files a duly executed "Special Election of
         Payment Method after a Change in Control" in the form attached hereto
         as Schedule "B").

         3. Nothing contained herein shall be held to alter, vary or affect any
of the terms, provisions, or conditions of the Plan, other than as stated above.

         AGREEMENT made this 15th day of September, 1997 (the "Effective Date"),
between The Mahoning National Bank of Youngstown (hereinafter referred to a the

                                    ARTICLE I

                                    PURPOSES

         The purposes of this Plan are: (a) to enable the Bank to retain the
Executive in its employ; and (b) to reward the Executive for the time and effort
he expends in his job and for the success achieved.

                                   ARTICLE II

                                   DEFINITIONS

         The terms used in this Plan shall have the following meanings:

(a)      "Aggregate Phantom Stock Account Value" shall mean the sum of the
         Phantom Stock Account Value plus all distributions made to the
         Executive pursuant to Article VII, Section (c), prior to the date said
         Executive terminates his employment with the Bank.

(b)      "Change in Control" shall mean:

         majority of the Bank's or the Company's directors; or

         (iii) the acquisition of a controlling influence over the management or
         policies of the Bank or the Company by any person or by persons acting
         as a "group" (within the meaning of Section 13(d) of the Securities
         Exchange Act of 1934); or

         (iv) during any period of two consecutive years, individuals (the
         "Continuing Directors") who at the beginning of such period constitute
         the Board of Directors of the Bank or the Company (the "Existing
         Board") cease for any reason to constitute at least two-thirds thereof,
         provided that any individual whose election or nomination for

         election as a member of the Existing Board was approved by a vote of at

         Notwithstanding the foregoing, in the case of (i), (ii) and (iii)
         hereof, ownership or control of the Bank by the Company itself shall
         not constitute a Change in Control. For purposes of this paragraph
         only, the term "person" refers to an individual or a corporation,

         proprietorship, unincorporated organization or any other form of entity

         Notwithstanding the foregoing, no trust department or other designated
         fiduciary or other trustee of such trust department of the Bank or a
         subsidiary of the Bank, or other similar fiduciary capacity of the Bank
         with direct voting control of the stock shall be included or
         considered. Further, no profit-sharing, employee stock ownership,
         employee stock purchase and savings, employee pension, or other

         included or considered.

         Vested Account Value reasonably estimated as of the closing date of the
         Change in Control, and (ii) the present value, which shall in no event
         be less than zero, of the difference between (a) and (b) hereof,
         assuming a discount at the current long-term applicable federal rate,
         compounded monthly, for a period of 15 years.

                  (a) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to 8%.

                  (b) The future value determined by assuming that the Net
                  Vested Account Value determined in accordance with clause (i)
                  above appreciates for 15 years at a rate equal to the current
                  long-term applicable federal rate (compounded monthly).

(d)      "Committee" means the members of the Executive Committee of the Board
         of Directors of the Bank who are not participants in this Plan.

         the aggregate of all distributions to the Participant pursuant to
         Article VII, Section (c).

(i)      "Permanent Disability" shall mean a situation in which the Executive is
         permanently physically or mentally unable to perform his customary
         and/or required duties at the Bank. The determination as to whether or

         Committee, and such determination shall be conclusive. Provided,
         however, if the Executive is disabled for purposes of the Bank's
         disability insurance plan, he shall be conclusively determined to be
         disabled under this Plan.

(j)      "Phantom Stock Account Value" means the number of Phantom Shares
         credited to a Participant's account multiplied by the average fair
         market value, over the 10 business days preceding the date of any
         valuation, of the Common Stock of Mahoning National Bancorp, Inc.
         Notwithstanding the foregoing, in the event of the sale or merger of
         the Holding Company, the sale or merger price of the Common Stock shall
         determine the Executive's Phantom Stock Account Value.

(k)      "Retirement" means a severance from the employment of the Bank under
         the Bank's qualified benefit plan as constituted at present or as may

         employment with the Bank by reason of death, disability, retirement,
         resignation, or otherwise.

(n)      "Vested Account Value" shall equal the Aggregate Phantom Stock Account
         Value multiplied by the applicable Vesting Percentage set forth in
         Schedule A attached hereto.

(o)      "Vesting Percentage" shall mean that percentage listed on Schedule A,
         which is attached hereto, which corresponds with the age of the
         Executive, at any given time. However, advances and or changes in the
         vesting schedule with respect to a change in the age of the Executive
         shall be made only on December 31 of each calendar year during which
         Executive attained the stated age.

                                   ARTICLE III

                                 ADMINISTRATION

(a)      The complete and sole administration of this Plan is the responsibility
         of those members of the Committee who are not Participants. No member
         of the Committee shall be liable for any act done or determination made
         in good faith.

(b)      The construction and interpretation by the Committee of any provisions
         of this Plan shall be final and conclusive. The Committee shall
         determine, from time to time,


                                       3


<PAGE>   11


         subject to the provisions of this Plan, the Executives who shall
         participate in the Plan (sometimes hereinafter called "Participants").

(c)      The Committee may, at its discretion, delegate its duties to the
         outside auditors of the Bank, but may not delegate its authority to
         apply or interpret the provisions of this Plan or to make
         determinations specified in Section (b) of this Article III.

                                   ARTICLE IV

                     ESTABLISHMENT OF PHANTOM STOCK ACCOUNT

         The Bank shall set up an appropriate record (hereinafter called the
"Phantom Stock Account") in the name of each Executive under the Plan, and shall
record all activities of this agreement in the respective Phantom Stock Accounts
of each Executive.

                                    ARTICLE V

                        CREDITS TO ACCOUNTS OF EXECUTIVES

(a)      As of December 31st of each year that the Executive is a full-time
         employee of the Bank, the Bank shall credit a number of Phantom Shares
         of the Holding Company to the account of each Executive. The number of
         Phantom Shares to be credited each year shall be determined by dividing
         the Bank's contribution by the fair market value of the Holding
         Company's Common Stock as of the date of crediting (December 31). The
         contribution by the Bank each year shall be a percentage of the
         Executive's salary as determined by the return on equity of the Bank
         for the year pursuant to a schedule to be established by the Committee
         no later than the close of the first quarter of that year.

         The ultimate computation of the number of Phantom Shares to be credited
         each year will be determined by interpolation for performance between
         the three levels established (i.e., threshold, target, and
         distinguished), and return on equity will be calculated after projected
         expense attributable to the incentive pay out. Determination of the
         number of Phantom Shares shall be solely by the Committee and shall be
         final and binding on all parties. Provided, however, if the ROE is
         below the threshold for the year, then no crediting based on a
         percentage of pay for the year shall be made.

(b)      So long as this Plan remains in effect, the Bank shall credit each
         Participant's account in the special ledger throughout the term of his
         employment with the Bank. Phantom Shares equivalent to dividends
         payable in cash or property paid from time to time on issued and
         outstanding shares of Common Stock, so that the amount of each such
         credit will be equivalent to dividends which the Participant would have
         received had he been the owner of the number of shares of Common Stock
         equal to the number of Phantom Shares in his account. No such credit
         shall be made with respect to any dividend paid after a Participant's
         termination of employment or after any date of termination of this
         Plan, even though the record date is prior thereto.

<PAGE>   12


(c)      In the event of any stock dividend on the Common Stock or any split-up
         or combination of shares of the Common Stock, appropriate adjustments
         shall be made by the Committee in the aggregate number of Phantom
         Shares in the account of the Participant. However, the Committee shall
         not be required to establish any fractional Phantom Shares.

(d)      On or before January 31st of each year, the Bank shall provide to each
         Executive a detail of his Phantom Share Account as of December 31 of
         the previous year. This detail shall include the number of Phantom
         Shares in the Executive's account, and the Net Vested Account Value.


                                   ARTICLE VI

                                     VESTING

         So long as the Executive remains an employee of the Bank, he shall
continue to advance in the vesting schedule attached as Schedule A. Upon the
Executive's termination of employment with the Bank, he shall be permanently
vested according to the percentage given on Schedule A on the same line as his
age on the date of his termination of employment. Provided, however, if the
Executive, while in the employ of the Bank, dies or becomes permanently
disabled, he shall become permanently 100% vested. Moreover, if a Change in
Control shall occur while the Executive remains in the employ of the Bank, the
Executive shall also become permanently 100% vested.


                                   ARTICLE VII

                              PAYMENTS OF BENEFITS

(a)      Upon termination of any Participant's employment with the Bank, there
         shall be paid to him, or in the event of his death to his beneficiary
         or beneficiaries designated under Section (b) of this Article VII, an
         amount equal to the Net Vested Account Value of such Participant,
         determined in accordance with the valuation formula set forth in
         Article II, Section (j) as of the date of termination of employment of
         such Participant. Such amounts will be reduced by any amounts required
         by law to be withheld by the Bank. Such amounts with interest at the
         rate of eight percent (8%) per annum shall be distributed in the manner
         elected by the Executive on an Election Form accepted by the Bank. The
         Executive may elect (1) to begin receiving distributions from his
         account on either the first day of the second month after termination
         of service with the Bank or the first day of second month of the
         calendar year immediately after termination of service with the Bank
         and (2) to receive his benefits in either a lump-sum or in
         substantially equal monthly installments over a period up to 15 years.

         In order to be effective with respect to the timing of distributions,
         the Executive's Election Form must be submitted to the Bank either more
         than one year before the date on which the Executive's service with the
         Bank terminates for any reason or within 30 days of the Plan's
         Effective Date. In the absence of a validly completed Election


                                       5

<PAGE>   13


         Form, the Executive's account shall be paid in 60 substantially equal
         monthly payments beginning on the first day of the second month after
         termination of service with the Bank.

(b)      Each person shall file an Election Form with the Bank's Employee
         Benefits Plan Administrator designating one or more beneficiaries to
         whom payments otherwise due the Executive shall be made in the event of
         his death while in the employ of the Bank or after termination
         therefrom. The beneficiary or beneficiaries so designated shall be one
         or more persons or entities, including a trust or estate, other than
         his creditors, or the creditors of his estate, or an entity in which
         any of the foregoing may have an interest. The Executive shall have the
         right to change the beneficiary or beneficiaries from time to time
         whether before or after termination of employment; provided, however,
         that any change shall not become effective until an Election Form is
         received by the Employee Benefits Plan Administrator.

         If the Executive dies before receiving all amounts payable of his Net
         Vested Account Value, then the remaining balance of the Executive's
         account shall be distributed in a lump sum to the Executive's
         designated beneficiary (or estate, in the absence of a validly named or
         living beneficiary) as soon as administratively practicable following
         the Executive's death; provided that the Executive may direct on an
         Election Form that any death benefits payable pursuant to this
         Agreement shall instead be distributed over a distribution period that
         effectuates the monthly installment payments selected by the Executive
         (with payments made as though the Executive survived to collect all
         payments, and terminated service on the date of his death if payments
         had not previously begun).

(c)      At the time of the college education of a child of an Executive, an
         amount of money equal to the actual expenses associated with such
         child's education may, upon application of the Executive, be disbursed
         for such purposes by the Committee, in the Committee's sole discretion,
         from the Net Vested Account Value of the Executive's Phantom Stock
         Account.

                                  ARTICLE VIII

                            RESTRICTIONS UPON FUNDING

(a)      The Bank shall have no obligation to set aside, earmark or entrust any
         fund or money with which to pay its obligations under this Agreement.
         The Executive, his beneficiaries or any successor in interest to him
         shall be and remain simply a general creditor of the Bank in the same
         manner as any other creditor having a general claim for matured and
         unpaid compensation.

(b)      Subject to subsection (d) hereof, the Bank reserves the absolute right
         in its sole discretion to either fund the obligations undertaken by
         this Agreement or to refrain from funding the same and to determine the
         extent, nature, and method of such funding. Should the Bank elect to
         fund this Agreement, in whole or in part, through


                                       6

<PAGE>   14


         the purchase of life insurance, mutual funds, disability policies or
         annuities, the Bank reserves the absolute right, in its sole
         discretion, to terminate such funding at any time, in whole or in part.
         At no time shall Executive be deemed to have any lien nor right, title
         or interest in or to any specific funding investment or to any assets
         of the Bank.

(c)      If Bank elects to invest in a life insurance, disability or annuity
         policy upon the life of Executive, then Executive shall assist the Bank
         by freely submitting to a physical exam and supplying such additional
         information necessary to obtain such insurance or annuities.

(d)      Not later than ten business days before the closing date of a Change in
         Control, the Bank shall --

         (i)      deposit in a grantor trust (the "Trust") that is designed in
                  accordance with Revenue Procedure 92-64 and has a trustee
                  independent of the Bank and the Company an amount equal to the
                  Change-in-Control Account Value, unless the Executive has
                  previously provided a written release of any claims under this
                  Agreement, and

         (ii)     provide the trustee of the Trust with a written direction to
                  hold said amount and any investment return thereon in a
                  segregated account for the benefit of the Executive, and to
                  follow the payment schedule to be provided by the Executive,
                  based on this Agreement and the Executive's Election Form, as
                  to the payment of amounts from the Trust.

Upon the Trust's final payment of all amounts due under this Section (d) of
Article VIII, the trustee of the Trust shall pay to the Bank the entire balance
remaining in the segregated account maintained for the benefit of the Executive.
The Executive shall thereafter have no further interest in the Trust.

                                   ARTICLE IX

                                  MISCELLANEOUS

(a)      Neither Executive, his widow nor any other beneficiary under this
         Agreement shall have any power or right to transfer, assign,
         anticipate, hypothecate, mortgage, commute, modify or otherwise
         encumber in advance any of the benefits payable hereunder, nor shall
         any of said benefits be subject to seizure for the payment of any
         debts, judgments, alimony or separate maintenance owed by the Executive
         or his beneficiary, nor be transferable by operation of law in the
         event of bankruptcy, insolvency or otherwise. In the event Executive or
         any beneficiary attempts assignment, commutation, hypothecation,
         transfer or disposal of the benefits hereunder, the Bank's liabilities
         shall forthwith cease and terminate. However, in such event, the
         Committee may, in its sole discretion, from time to time, make payments
         of amounts which would otherwise be due the Executive hereunder, to
         such Executive.

(b)      The Bank expressly agrees that it shall not merge or consolidate into
         or with another Bank or sell substantially all of its assets to another
         corporation, firm or person until such corporation, firm or person
         expressly agrees, in writing, to assume and discharge the duties and
         obligations of the Bank under this Agreement. This Agreement shall be
         binding upon the parties hereto, their successors, beneficiaries, heirs
         and personal representatives.

(c)      It is agreed by and between the parties hereto that, during the
         lifetime of the Executive, this Agreement may be amended or revoked at
         any time or times, in whole or in part, by the mutual written assent of
         the Executive and the Bank.

(d)      Whenever in this Agreement words are used in the masculine or neuter
         gender, they shall be read and construed as in the masculine, feminine
         or neuter gender, whenever they should so apply.

(e)      Nothing contained in this Agreement shall affect the right of the
         Executive to participate in or be covered by any qualified or
         non-qualified pension, profit sharing, group, bonus or other
         supplemental compensation or fringe benefit plan constituting a part of
         the Bank's existing or future compensation structure.

(f)      Headings and Subheadings in this Agreement are inserted for reference
         and convenience only and shall not be deemed a part of this Agreement.

(g)      The validity and interpretation of this Agreement shall be governed by
         the laws of the State of Ohio.

                                    ARTICLE X

                                ERISA PROVISIONS

(a)      The "Named Fiduciary and Plan Administrator" of this Plan shall be the
         Bank's Employee Benefits Plan Administrator until his resignation or
         removal by the Committee. As named Fiduciary and Administrator, the
         Employee Benefits Plan Administrator shall be responsible for the
         management, control and administration of the Executive Phantom Stock
         Bonus Plan as established herein. He may delegate to others certain
         aspects of the management and operation responsibilities of the Plan
         including the employment of advisors and the delegation of ministerial
         duties to qualified individuals.

(b)      In the event that benefits under this Plan Agreement are not paid to
         the Executive (or to his beneficiary in the case of the Executive's
         death) and such claimants feel they are entitled to receive such
         benefits, then a written claim must be made to the Named Fiduciary and
         Plan Administrator named above within sixty (60) days from the date
         payments are refused. The Named Fiduciary and Plan Administrator and
         the Bank shall review the written claim and if the claim is denied, in
         whole or in part, they shall provide in writing within ninety (90) days
         of receipt of such claim their specific reasons


                                       8

<PAGE>   16



         for such denial, reference to the provisions of this Agreement upon
         which the denial is based and any additional material or information
         necessary to perfect the claim. Such written notice shall further
         indicate the additional steps to be taken by claimants for a further
         review of the claim denial if the Named Fiduciary and Plan
         Administrator fails to take any actions within the aforesaid ninety-day
         period.

         If claimants desire a second review, they shall notify the Named
         Fiduciary and Plan Administrator in writing within sixty (60) days of
         the first claim denial. Claimants may review the Plan Agreement or any
         documents relating thereto and submit any written issues and comments
         they may feel appropriate. In its sole discretion, the Named Fiduciary
         and Plan Administrator shall then review the second claim and provide a
         written decision within sixty (60) days of receipt of such claim. This
         decision shall likewise state the specific reasons for the decision,
         and shall include reference to specific provisions of the Plan
         Agreement upon which the decision is based.

         If claimants continue to dispute the benefit denial based upon
         completed performance of the Agreement or the meaning and effect of the
         terms and conditions thereof, then claimants may submit the dispute to
         a Board of Arbitration for final arbitration. Said Board shall consist
         of one member selected by the claimant, one member selected by the Bank
         and the third member selected by the first two members. The Board shall
         operate under any generally recognized set of arbitration rules. The
         parties hereto agree that they and their heirs, personal
         representatives, successors and assigns shall be bound by the decision
         of such Board with respect to any controversy properly submitted to it
         for determination.

                                   ARTICLE XI

             REIMBURSEMENT OF EXECUTIVE FOR ENFORCEMENT PROCEEDINGS

         In the event that any dispute arises between the Executive and the Bank
as to the terms or interpretation of this Agreement, whether instituted by
formal legal proceedings or otherwise, including any action that the Executive
takes to defend against any action taken by the Bank or the Company, the Bank
shall reimburse the Executive for all costs and expenses, including reasonable
attorneys' fees, arising from such dispute, proceedings or actions, provided
that the Executive obtains either a written settlement or a final judgement by a
court of competent jurisdiction substantially in his favor. Such reimbursement
shall be paid within ten days of Executive's furnishing to the Bank written
evidence, which may be in the form, among other things, of a canceled check or
receipt, of any costs or expenses incurred by the Executive.

                                  ELECTION FORM
                         -------------------------------


         AGREEMENT, made this ____ day of ________, 19__, by and between the
undersigned executive (the "Executive") and The Mahoning National Bank of
Youngstown (the "Bank") with respect to distribution of the benefits pursuant to
The Mahoning National Bank of Youngstown Executive Phantom Stock Bonus Plan (the
"Plan") entered into by the parties on September 15, 1997.

         NOW THEREFORE, it is mutually agreed as follows:

         1. FORM OF PAYMENT. The Executive elects to have his account
            distributed as follows:

            [      ]  in one lump sum payment.

            [      ]  in substantially equal monthly payments over a
                      period of _____ years (no more than 15).

         The Executive must make this election EITHER at least one year before
terminating his service with the Bank or by October 15, 1997 in order for it to
be valid and supersede a prior election.

         2. The Executive elects to have distributions from his account begin:

            [      ]  on the first day of the second month immediately
                      following the date in which the Executive ceases 
                      service with the Bank.

            [      ]  on the first day of the second month of the calendar
                      year immediately following the year in which the Executive
                      ceases service with the Bank.

         3. In the event of the Executive's death, his account shall be
            distributed:

            [      ]  in one lump sum payment.

            [      ]  in accordance with the payment schedule selected in
                      paragraph 1 hereof (with payments made as though the
                      Executive survived to collect all benefits, and as though
                      the Executive terminated service on the date of his death,
                      if payments had not already begun).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A - Summary of Accounting Policies

The financial information presented is prepared in accordance with generally
accepted accounting principles (GAAP) and general policies within the financial
services industry. Unless otherwise indicated amounts are in thousands, except
per share data.

1.   PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of Mahoning
     National Bancorp, Inc. (the Company) and its wholly-owned subsidiary The
     Mahoning National Bank of Youngstown (the Bank). All significant
     intercompany balances and transactions have been eliminated in
     consolidation.

2.   INDUSTRY SEGMENT INFORMATION

     The Company is a one-bank holding company engaged in the business of
     commercial and retail banking, and trust and investment services, with
     operations conducted through its main office and branches located
     throughout Mahoning and Trumbull Counties of Ohio. Mahoning and Trumbull
     Counties provide the source for substantially all of the Company's deposit,
     loan and trust activities. The majority of the Company's income is derived
     from commercial and retail business lending activities and investments.

3.   USE OF ESTIMATES

     In preparing financial statements in conformity with GAAP, management is
     required to make estimates and assumptions that affect the reported amounts
     of assets and liabilities and the disclosure of contingent assets and
     liabilities at the date of the financial statements and revenues and
     expenses during the reporting period. Actual results could differ from
     those estimates. Areas involving the use of management's estimates and
     assumptions include the allowance for loan losses, the realization of
     deferred tax assets, fair values of certain securities, the determination
     and carrying value of impaired loans, the carrying value of loans held for
     sale, the carrying value of other real estate, depreciation of premises and
     equipment, the postretirement benefit obligation, the actuarial present
     value of pension benefit obligations, net periodic pension expense and
     prepaid pension costs recognized in the Company's financial statements.
     Estimates that are more susceptible to change in the near term include the
     allowance for loan losses and the fair value of certain securities.

4.   CASH AND CASH EQUIVALENTS

     The Company includes demand deposits at other financial institutions as
     cash equivalents.

5.   INVESTMENT AND AVAILABLE FOR SALE SECURITIES

     Investments are classified in up to three categories and accounted for
     based on the respective classification. Debt securities that the Company
     has the positive intent and ability to hold to maturity are classified as
     held to maturity and reported at amortized cost. Securities bought and held
     principally for the purpose of selling them in the near term are classified
     as trading securities and reported at fair value, with unrealized gains and
     losses included currently in income. Equity securities and debt securities
     classified as neither held to maturity nor trading securities are
     classified as available for sale and reported at fair value, with
     unrealized gains and losses excluded from income and reported as a separate
     component of stockholders' equity. The Company did not classify any debt or
     equity securities as trading securities in 1998, 1997 or 1996. Realized
     gains and losses from sales of debt and equity securities are determined by
     specific identification of the security sold. Substantially all interest
     earned from obligations of state and political subdivisions is not subject
     to federal income tax.

6.   LOANS

     Loans are stated at the principal amount outstanding net of the unamortized
     balance of deferred direct loan origination fees and costs. These net
     deferred fees and costs are amortized over the lives of the related loans
     as an adjustment to interest income using the interest method. Interest is
     accrued as earned unless the collectibility of the loan is in doubt.
     Uncollectible interest on loans that are contractually past due is charged
     off to interest income to the extent of all interest previously accrued,
     and income is subsequently recognized only to the extent that cash payments
     are received until, in management's judgment, the borrower's ability to
     make periodic interest and principal payments has returned to normal, in
     which case the loan is returned to accrual status.

     The carrying value of loans classified as impaired is periodically adjusted
     to reflect cash payments, revised estimates of future cash flows and
     increases in the present value of expected cash flows due to the passage of
     time. Cash payments representing interest income are reported as such and
     other cash payments are reported as reductions in carrying value. Increases
     or decreases in carrying value due to changes in estimates of future
     payments or the passage of time are reported as reductions or increases in
     the provision for loan losses.

     On January 1, 1996, the Company adopted Statement of Financial Accounting
     Standards ("SFAS") No. 122, "Accounting for Mortgage Servicing Rights,"
     which requires that a mortgage banking enterprise recognize as a separate
     asset, rights to service mortgage loans for others, however those servicing
     rights are acquired. In circumstances where mortgage loans are originated,
     separate asset rights to service mortgage loans are only recorded when the
     Company intends to sell such loans. Mortgage servicing assets are amortized
     against future service fee income based on the anticipated life of the
     loans sold. The adoption of this new statement did not have a material
     impact on the Company's consolidated financial position or results of
     operations.

     Loans held for sale are reported at the lower of cost or market value in
     the aggregate.

7.   ALLOWANCE FOR POSSIBLE LOAN LOSSES

     The determination of the balance of the allowance for possible loan losses
     is based on analysis of loans and evaluation of among other items, economic
     factors, identified problem loans, delinquencies and charge-off experience.
     The balance reflects an amount which, in management's judgment, is adequate
     to provide for probable loan losses. The annual provision for loan losses
     is charged as an operating expense on the consolidated statement of income.

     A loan is defined as impaired when, based on current information and
     events, it is probable that a creditor will be unable to collect all
     amounts due according to the contractual terms of the loan agreement.
                                                                              5
<PAGE>   8
                                      Notes to Consolidated Financial Statements

Note A - continued
     The Company considers its investment in one-to-four family residential
     loans, consumer installment loans and credit card loans to be homogeneous
     and, therefore, excluded from separate identification for evaluation of
     impairment. With respect to the Company's investment in impaired commercial
     loans, nonresidential mortgage loans and nonrated industrial development
     obligations, such loans are generally collateral-dependent, and as a
     result, are carried as a practical expedient at the lower of cost or fair
     value.

     It is the Company's policy to charge off unsecured commercial credits that
     are more than ninety days delinquent. Similarly, collateral-dependent loans
     which are more than ninety days delinquent are considered to constitute
     more than a minimum delay in repayment and are evaluated for impairment at
     that time.

8.   BANK PREMISES AND EQUIPMENT

     Bank premises and equipment are stated at cost, less accumulated
     depreciation and amortization. Depreciation is provided for in amounts
     sufficient to relate the cost of depreciable assets to operations over
     their estimated service lives on a straight-line basis. Leasehold
     improvements are amortized over the lives of the respective leases or the
     service lives of the improvements, whichever is less.

9.   OTHER REAL ESTATE OWNED

     Other real estate owned is comprised of properties acquired through
     foreclosure proceedings or acceptances of deeds in lieu of foreclosure.
     These properties are included in other assets initially at the lower of
     cost or fair value, less estimated selling costs. Any reduction from
     carrying value of the related loan to fair value at the time of acquisition
     is accounted for as a loan loss. Any subsequent reduction in fair value is
     reflected as a charge to income. Expenses to carry other real estate are
     charged to operations as incurred. Other real estate owned at December 31,
     1998 and 1997 totaled $0 and $1.112 million, respectively.

10.  INCOME TAXES

     The Company follows the liability method of accounting for income taxes.
     The liability method provides that deferred income taxes are recognized for
     the tax consequences of temporary differences by applying enacted statutory
     tax rates applicable to future years to differences between the financial
     statement carrying amounts and the tax bases of existing assets and
     liabilities. The effect on deferred taxes of a change in tax rates is
     recognized in income in the period that includes the enactment date.

11.  BENEFIT PLANS

     The Bank provides certain health care and life insurance benefits for
     certain retired employees with twenty or more years of service. The Company
     records an accrual for the estimated costs of providing postretirement
     benefits over the employee service periods. Upon adoption of SFAS 106, the
     Company elected to defer recognition of the accumulated postretirement
     benefit obligation existing at January 1, 1993 (transition obligation) of
     approximately $2.134 million. The transition obligation is being amortized
     as part of postretirement costs over a twenty year period. The funding of
     these benefits is made as incurred.

     The Bank maintains a noncontributory defined benefit pension plan covering
     substantially all full-time employees. Benefit payments for normal
     retirement are based on employees' years of service and highest five year
     average compensation. The Bank's policy is to contribute an amount annually
     to the plan that is tax deductible under the Internal Revenue Code. Pension
     expense is computed in accordance with SFAS Nos. 87 and 88.

     The Bank has established deferred compensation and phantom stock plans with
     certain officers and an elective contributory defined contribution 401 (k)
     plan which is offered to substantially all employees. The cost of the
     deferred compensation and phantom stock plans are recognized over the
     participants respective vesting schedules. Bank contributions to the 401
     (k) plan, which are discretionary, are expensed when determined. The
     Company recognized expenses totaling $350 thousand, $537 thousand and $251
     thousand in connection with these benefit plans for the years ended
     December 31, 1998, 1997 and 1996, respectively.

12.  EARNINGS PER SHARE

     Earnings per share is computed by dividing net income by the weighted
     average number of shares outstanding during the year. Weighted average
     shares outstanding for each of the years ended 1998, 1997 and 1996 were
     6.300 million.

13.  TRUST DEPARTMENT ASSETS AND INCOME

     Property (other than cash deposits) held by the Bank in fiduciary or agency
     capacities for its customers is not included in the accompanying
     consolidated statements of financial condition since such items are not
     assets of the Bank. Trust department income is recognized on the cash basis
     which materially approximates amounts that would be recognized under the
     accrual method.

14.  FAIR VALUES OF FINANCIAL INSTRUMENTS

     The consolidated financial statements include estimated fair value
     information as of December 31, 1998 and 1997. Such information, which
     pertains to the Company's financial instruments, is based on the
     requirements set forth in SFAS 107 and does not purport to represent the
     aggregate net fair value of the Company. Further, the fair value estimates
     are based on various assumptions, methodologies and subjective
     considerations, which may vary widely among different financial
     institutions and which are subject to change.

     The following methods and assumptions were used by the Company in
     estimating financial instrument fair values:

     Cash and cash equivalents and federal funds sold
     ------------------------------------------------
     The statement of financial condition carrying amounts for cash and federal
     funds sold equal the estimated fair values of such assets.

     Investment securities
     ---------------------
     Fair values for investment securities are based on quoted market prices, if
     available. If quoted market prices are not available, fair values are based
     on quoted market prices of comparable instruments.

                                      Notes to Consolidated Financial Statements

Note A - continued

     Loans receivable
     ----------------
     For variable rate loans which reprice frequently and which entail no
     significant change in credit risk, fair values are based on the carrying
     values. The estimated fair values of fixed rate loans are estimated based
     on discounted cash flow analyses using interest rates currently offered for
     loans with similar terms to borrowers of similar credit quality.

     Off-balance sheet instruments
     -----------------------------
     The Bank is a party to financial instruments with off-balance sheet risk in
     the normal course of business to meet the financing needs of its customers.
     These financial instruments include commitments to extend credit through
     loans approved, but not yet funded, lines of credit and standby letters of
     credit. Since some of these commitments may not be utilized, or utilized in
     amounts less than the total committed, the total commitment amounts do not
     necessarily represent future cash requirements. Management has determined
     that due to the uncertainties of cash flows and difficulty in predicting
     the timing of such cash flows, fair values could not be reasonably
     estimated for these instruments. However, such amounts would not be
     significant.

     Accrued interest
     ----------------
     The carrying amounts of accrued interest receivable and accrued interest
     payable approximate their fair values.

     Deposit liabilities
     -------------------
     The fair values estimated for deposits subject to withdrawal on demand
     (e.g., interest and noninterest bearing checking accounts, savings accounts
     and certain types of money market accounts) are, by definition, equal to
     the amount payable at the reporting date (i.e., their carrying amounts).
     The carrying amounts of variable rate time deposits approximate their fair
     values at the reporting date. Fair values of fixed rate time deposits are
     estimated using discounted cash flow analyses using interest rates
     currently offered to a schedule of aggregated expected time deposit
     maturities.

     Short term borrowings
     ---------------------
     The carrying amounts of federal funds purchased, borrowings under
     repurchase agreements, and other short term borrowings approximate their
     fair values.

     Long term borrowings
     --------------------
     The fair value of fixed-rate long term borrowings are estimated using
     discounted cash flow analyses at interest rates currently offered to the
     borrowing repayment schedules.

15.  RECLASSIFICATIONS

     Certain reclassifications have been made to the prior year's consolidated
     financial statements to conform to the current year presentation. The
     reclassifications had no effect on net income or stockholders' equity.


Note B - Investment Securities

investment securities available for sale and held to maturity at December 31,
1998 and 1997 are as follows:

The change in net deferred tax each year represents the effect of changes in the
amounts of temporary differences. The Company has not established a valuation
allowance as it is management's belief that it has adequate taxable income and
carrybacks to realize the net deferred tax asset. The sources of gross deferred
tax assets and gross deferred tax liabilities are as follows:

Note K - Commitments and Contingencies

There are various contingent liabilities that are not reflected in the financial
statements, including claims and legal actions arising in the ordinary course of
business. In the opinion of management, after consultation with legal counsel,
the ultimate disposition of these matters is not expected to have a material
effect on the Company's financial condition or results of operations.

At year-end 1998 and 1997, reserves of $1.690 million and $11.152 million were
required as deposits with the Federal Reserve or as cash on hand. These reserves
do not earn interest.

The Bank grants commercial and industrial loans, commercial and residential
mortgages, and consumer loans to customers in the Mahoning Valley. Although the
Bank has a diversified portfolio, exposure to credit loss can be adversely
impacted by downturns in local economic and employment conditions.

The Bank is party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers. These
financial instruments include commitments to extend credit through loans
approved, but not yet funded, lines of credit and standby letters of credit. The
Bank uses the same credit policies in making commitments and conditional
obligations as it does for on-balance sheet instruments. The Bank evaluates each
customer's creditworthiness on a case-by-case basis, and the amount of
collateral obtained is based upon the credit evaluation. Collateral held varies
but may include accounts receivable, inventory, property, plant and equipment,
income-producing properties, stocks, bonds, certificates of deposit and other
deposit accounts, real estate and vehicles. Commercial loans may also require
the personal guarantees of various business owners and/or key management. 

The commitments to extend credit generally have fixed expiration dates or other
termination clauses and may require payment of a fee. Since some of these
commitments may not be utilized, or utilized in amounts less than the total
committed, the total commitment amounts do not necessarily represent future cash
requirements. The majority of the unfunded commitments at December 31, 1998 are
variable rate commitments, with approximately 10% or $17 million having fixed
rates. A summary of estimated commitments to extend credit at December 31, 1998
and 1997, follows:

Note L - Stockholders' Equity

On April 15, 1996, the Board of Directors authorized a stock split in the amount
of 3,150,000 shares. The stock split, effected in the form of a stock dividend,
was issued on May 15, 1996. After issuance of the stock dividend, the Company
had 6,300,000 shares of its 15,000,000 authorized shares of no par value common

The approval of the Comptroller of the Currency is required for national banks
to pay dividends in excess of earnings retained in the current year plus
retained net profits for the preceding two years. As of December 31, 1998,
approximately $1.698 million of undistributed earnings of the Bank was available
for distribution to the parent company as dividends without prior regulatory
approval. 

The Company and Bank are subject to regulatory capital requirements
administered by federal banking agencies. Capital adequacy guidelines and prompt
corrective action regulations involve quantitative measures of assets,
liabilities and certain off-balance-sheet items calculated under regulatory
accounting practices. Capital amounts and classifications are also subject to
qualitative judgments by regulators about components, risk weightings and other
factors, and the regulators can lower classifications in certain cases. Failure
to meet various capital requirements can initiate regulatory action that could
have a direct material effect on the financial statements. 

The prompt corrective action regulations provide five classifications, including
well capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized and critically undercapitalized, although these terms are not
used to represent overall financial condition. If adequately capitalized,
regulatory approval is required to accept brokered deposits. If
undercapitalized, capital distributions are limited, as is asset growth and
expansion, and plans for capital restoration are required. The minimum
requirements are:

Board of Directors and Stockholders
Mahoning National Bancorp, Inc.

     We have audited the accompanying consolidated statements of financial
condition of Mahoning National Bancorp, Inc. as of December 31, 1998 and 1997
and the related consolidated statements of income, changes in stockholders'
equity and cash flows for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Mahoning
National Bancorp, Inc. as of December 31, 1998 and 1997 and the consolidated
results of its operations and its consolidated cash flows for each of the three
years in the period ended December 31, 1998, in conformity with generally
accepted accounting principles.

                            Report on Internal Controls over Financial Reporting



                         MAHONING NATIONAL BANCORP, INC.
                                23 FEDERAL PLAZA

     Management is responsible for preparing financial statements and
establishing and maintaining effective internal controls over financial
reporting presented in conformity with both generally accepted accounting
principles and the Federal Financial Institutions Examination Council
instructions for Consolidated Reports of Condition and Income (call report
instructions). The internal control system contains monitoring mechanisms, and
actions are taken to correct deficiencies identified.

     There are inherent limitations in the effectiveness of any system of
internal control, including the possibility of human error and the circumvention
or overriding of controls. Accordingly, even an effective internal control
system can provide only reasonable assurance with respect to financial statement
preparation. Further, because of changes in conditions, the effectiveness of an
internal control system may vary over time.

     Management assessed the Company's internal controls over financial
reporting presented in conformity with both generally accepted accounting
principles and call report instructions as of December 31, 1998. This assessment
was based on criteria for effective internal control over financial reporting
described in Statement on Auditing Standards No. 78 "Internal Control in a
Financial Statement Audit" issued by the Auditing Standards Board of the
American Institute of Certified Public Accountants. Based on this assessment,
management believes that, as of December 31, 1998, Mahoning National Bancorp,
Inc. maintained effective internal controls over financial reporting presented
in conformity with both generally accepted accounting principles and call report
instructions.

BUSINESS OVERVIEW

Mahoning National Bancorp, Inc.

Mahoning National Bancorp, Inc. (Mahoning National) is a one-bank holding
company located in Youngstown, Ohio, and has total assets of $824.644 million.
The sole subsidiary of the Company is The Mahoning National Bank of Youngstown.

Mahoning National, locally-owned and independent, serves the Mahoning-Shenango
Valley market area. This area has a population of approximately 600,000
residents served by Mahoning National's twenty-one (21) banking locations in
Mahoning and Trumbull Counties. As of December 31, 1998, Mahoning National
employed 411 individuals, or a full-time equivalent of 375 employees.

Mahoning National offers a full-range of financial products and services. The
core accounts are represented by an array of personal and nonpersonal checking
products that include interest and noninterest bearing checking accounts. A
comprehensive offering of credit products includes: installment loans, student
loans, home mortgages, construction loans, commercial loans, revolving lines of
credit, MasterCard(R), VISA(R) and home equity loans, which can accommodate a
full-range of individual borrower's needs.

Other retail products and services offered are: Certificates of Deposits, IRAs,
safe deposit boxes, wire transfers, night depository, U.S. savings bonds,
traveler's checks, money orders and cashiers checks.

To further meet the needs of its diversified customer base, the hours of
operation offered at Mahoning National were expanded; in fact, Mahoning National
provides a wide variety of delivery channels from which customers can choose to
accommodate their particular lifestyles. Traditional branch banking with
personalized, one-on-one service is available at all Mahoning National Branch
Offices, while telephone banking is also available by calling Mahoning
National's Centralized Customer Service Center. Continuing to grow in
popularity, TeleBank, Mahoning National's automated 24-hour-a-day telephone
response system, is also available, allowing all customers to bank at their
convenience.

Following its business strategy of providing customers with value-added products
and services, as well as to accommodate our business customers, in August,
Mahoning National Bank introduced ExecuBank, a new interactive Cash Management
system that instantly puts its customers in touch with their accounts 24 hours a
day, 7 days a week. This new PC-based electronic product allows authorized
individuals access to account cash positions, account management and funds
management within their accounts from the privacy of their own offices.

Mahoning National's trust and investment customers also have direct access to
their account information: customers can review receipts and disbursements and
determine portfolio market values via Trust Web, a confidential Internet
service, while other clientele have telephone access to review balances and make
investment changes through a user-friendly telephone Voice Response Unit.

Mahoning National continued its commitment to the Mahoning Valley by reinvesting
in its own franchise. In December 1998, Mahoning National Bank opened a new
state-of-the-art branch facility in Austintown. This 3,600-square-foot brick
facility houses a fully-functional Customer Service Counter, an innovative
approach to banking aimed at providing better, more efficient customer service.
Instead of having to wait in line for a teller, customers are now able to
perform all noncash transactions, such as deposits and payments, at the counter,
as well as obtain information regarding new accounts, check orders, loans,
account changes, safe deposit boxes and other financial products and services. A
Financial Services Center for alternative investment products, expanded hours
and drive-up facilities, including a drive-up ATM, further enhance customer
service at this new branch.

Mahoning National's Financial Services Center, located within the Bank's Trust
and Investments Department, makes alternative investment products, such as
annuities, mutual funds and accommodative brokerage services, available to
customers and the general public through an arrangement with a third-party
vendor.

Mahoning National also offers a full-range of trust services through its Trust
and Investments Department. The services are provided by highly educated
professionals and include Recordkeeping, Investment Management and Full
Administration for Agency, Estate, Trust and Employee Benefit accounts. The
Department also offers two, highly flexible and unique services known as
Preferred Living Trust and MNB Select Asset Allocation. These specialized
services are designed to cater specifically to investors growing their
portfolios and living trust clients not currently utilizing full administration
services.

A highly competitive financial market environment with both intra- and
interstate competition can be found throughout the State of Ohio. Mahoning
National's major competitors include local financial institutions, regional
financial institutions and large nonbanking investment concerns, such as
insurance and brokerage firms.

Mahoning National Bancorp, Inc., is subject to supervision and regulation by the
Federal Reserve Board under the Bank Holding Company Act of 1956, as amended.
Since it is a bank holding company, the services provided by Mahoning National
are required to be closely related to the business of banking. The only
subsidiary of Mahoning National is The Mahoning National Bank of Youngstown,
which is a national commercial bank. As a result of being a national bank,
Mahoning National Bank is supervised and regulated by the Office of the
Comptroller of the Currency and is subject to yearly examination.

MANAGEMENT'S DISCUSSION & ANALYSIS

Mahoning National Bancorp, Inc.

The following Management's Discussion and Analysis of the financial condition
and results of operations of Mahoning National Bancorp, Inc., (Company) should
be read in conjunction with the Consolidated Financial Statements, related Notes
and the Comparative Financial Data contained in this annual report.


Note regarding forward-looking statements

In addition to the historical information contained herein, the following
discussion contains forward-looking statements that involve risks and
uncertainties. When used herein, the terms "anticipates," "plans," "expects,"
"believes" and similar expressions as they relate to the Company or its
management are intended to identify such forward-looking statements. The
Company's actual results, performance or achievements may materially differ from
those expressed or implied in the forward-looking statement. Risks and
uncertainties that could cause or contribute to such material differences
include, but are not limited to, general economic conditions, interest rate
environment, competitive condition in the financial services industry, changes
in law, governmental policies and regulations and rapidly changing technology
affecting financial services.


Statements of Condition

Total assets at December 31, 1998 reached a historic high of $824.644 million,
which was an increase of $27.778 million or 3.5% over December 31, 1997 total
assets of $796.866 million. Total earning assets at December 31, 1998 were
$779.390 million, an increase of $27.347 million from the $752.043 million in
earning assets at December 31, 1997. This growth in earning assets was primarily
funded with a $14.040 million increase in Federal Home Loan Bank advances and a
$10.296 million increase in deposits.


Investment Portfolio

The deposits and other borrowings of the Company, in excess of required reserves
and operating funds of the Mahoning National Bank of Youngstown ("Mahoning
National" or "Bank"), are invested in loans, investment securities and federal
funds sold. The objective of the investment portfolio is to combine liquidity,
earnings and safety of the investment in a prudent manner so as to protect the
depositor, fulfill the responsibility to borrowers and offer a favorable return
to the stockholders.

At December 31, 1998, the investment portfolio totaled $264.947 million, (which
included a $3.726 million net unrealized gain on available for sale securities)
which was an increase of $14.191 million from December 31, 1997. In 1998,
$66.218 million of the portfolio matured compared to $36.480 million in 1997,
and $5.265 million was sold in 1998 compared to $22.242 million in 1997. These
matured and sold securities were reinvested into the portfolio in both 1998 and
1997.

At December 31, 1998, the Company has classified investment securities with
amortized cost and fair value of $237.311 million and $241.037 million,
respectively or 90% of the portfolio, as available for sale, with the remainder
of the portfolio classified as held to maturity. At December 31, 1997, the
Company had classified investment securities with amortized cost and fair value
of $188.104 million and $189.578 million, respectively, or 75% of the portfolio,
as available for sale, with the remainder of the portfolio classified as held to
maturity. No securities were transferred between categories in 1998 or 1997.
Those securities classified as available for sale will afford the Company's
Asset/Liability Committee the necessary flexibility to manage the portfolio to
meet liquidity needs that may arise. The Company did not hold any on- or
off-balance sheet derivatives during 1998 or 1997, and does not expect to in
1999. The carrying amount of investment securities available for sale at
December 31, 1998 reflects a net increase, related to unrealized gains, of
$3.726 million with a corresponding increase to stockholders' equity, net of
deferred taxes, of $2.422 million, compared to a net increase in the carrying
amount at December 31, 1997, of $1.474 million with a corresponding $958
thousand increase in stockholders' equity.

The Company's portfolio is comprised mainly of U.S. Treasuries and agencies
(86%) and obligations of state and political subdivisions (11%). The quality of
the portfolio is evidenced by 99.6% of the investments being AAA rated. At
December 31, 1998 the weighted average maturity of the portfolio was 2 years 5
months compared to 2 years 3 months at December 31, 1997. It is the Company's
intent to keep the average duration of the portfolio at this level in order to
assure adequate liquidity and to capitalize on potential changes in interest
rate environments.

During 1998, the Company continued to add tax-free municipals to the investment
portfolio in an effort to reduce its effective tax rate and improve net income.
The average balance of tax-free municipals for 1998 was $26.737 million, an
increase of $2.661 million over the 1997 average balance of $24.076 million and
$6.511 million over the 1996 average balance of $20.226 million. The Company
expects to continue to add to this portfolio in 1999.

The tax equivalent yield of the investment portfolio decreased by 1 basis point
from 6.13% in 1997 to 6.12% in 1998. For additional investment portfolio
information refer to Note B - Investment Securities found on pages 7 and 8 of
this report.


Loans

At December 31, 1998, loans outstanding totaled $490.743 million, which was a
decrease of $1.744 million or less than 1% from December 31, 1997 loan totals of
$492.487 million. While actual December 31, 1998 loan balances decreased,
average loan balances increased $2.199 million in 1998 compared to 1997. The
loan portfolio, which is the Company's most profitable earning asset, totaled
65% of average earning assets in 1998 compared to 67% in 1997. The loan to
deposit ratio at December 31, 1998 was 88.36% compared to 90.35% at December 31,
1997.

The loan portfolio, with the exception of nonresidential mortgages and consumer
loans, experienced a decline from December 31, 1997 totals due to a competitive
loan pricing environment and the Company's decision to maintain more strict
underwriting standards. As interest margins continue to shrink due to the flat
yield curve, loan pricing and loan terms have become very competitive. The
Company has made a decision not to chase loan volume with rates or terms that
would jeopardize the quality of the loan portfolio.

The area of largest growth in 1998 was nonresidential mortgages which increased
as a result of loan demand and results from business development efforts. This
growth was offset by a decrease in residential mortgage loans that resulted from
the Company selling originated long term fixed rate mortgage loans in the
secondary market.

Nonresidential mortgages increased approximately $10.6 million or 10% in 1998
following $11.4 million or 12% growth in 1997. The continued strength of the
local economy, a good environment for construction and a favorable interest rate
environment contributed to the growth in 1998. The dollar fluctuation of
nonresidential mortgages can be more volatile than other loan products due to
the nature of the product and larger dollar amount of individual loans. As the
competition for nonresidential mortgages increases throughout 1999, with banks
looking to continue past growth trends in their loan portfolios, the Company
does not intend to compromise its credit standards for the sake of loan growth.

Residential mortgage loans declined approximately $11.5 million or 7% in 1998,
compared to $4.5 million or 3% growth in 1997. The 

                                                                           
                                                                              20

<PAGE>   23

                                              Management's Discussion & Analysis


Company, which was more active in the secondary market in 1998, sold
approximately $21.5 million in long term fixed rate mortgages compared to $1.0
million in 1997. The increase in the sale of long term fixed rate mortgages was
the result of an asset liability management strategy of not adding long term
fixed rate assets to the balance sheet. The Company expects to continue to
generate saleable loans, with servicing retained in 1999. With the current
emphasis on selling long term fixed rate mortgages in the secondary market and
continued refinancing pressures due to the historically low mortgage interest
rate environment, a continued decline in the residential mortgage loan portfolio
is expected in 1999.

Consumer loans increased approximately $1.1 million or 1% in 1998 after
increasing $7.0 million, or 5%, in 1997. Consumer loan balances are primarily
dependent on the level of indirect automobile financing purchased by the Bank.
The growth rate of 1997 was not sustained in 1998 due to a slower market,
greater competition among local lenders and the Company's close monitoring of
underwriting criteria due to the increased charge-offs and delinquency trends of
the past few years. Competition from leasing by captive automobile finance
companies (i.e. GMAC, Ford Motor Credit) continues to remain strong. These
companies have been offering a variety of below market lease and loan programs,
which has reduced the amount of new car financing available to bank lenders. To
effectively compete in this environment, the Company must continue to provide
the dealer network with a very high level of quality service that can help
offset lower rate alternatives. While the automobile financing market remains
highly competitive, the Company was able to increase market share through the
development of new dealer relationships and incentive plans for the dealer
network. In addition, the Company has benefited from regional bank competitors
consolidating operations out of the market area, which has not allowed them to
service the dealer network as efficiently as Mahoning National. The Company
currently purchases indirect auto loans from 100 dealers throughout the
Company's market area.


Deposits

Total deposits for 1998 increased $10.296 million, or 2%, to $555.407 million,
compared to a $5.887 million or 1% decrease in 1997. Savings and interest
bearing checking accounts decreased only $498 thousand, time deposits increased
$1.167 million while noninterest bearing demand deposits increased $9.627
million or 13% in 1998. The Company does not maintain any brokered deposits.
While actual deposit balances at December 31, 1998 increased $10.296 million
from year-end balances of 1997, the Company's average deposit totals for 1998,
$544.242 million, remained at approximately the same level as 1997, $543.335
million. While deposits increased in 1998, consumers continue to move their
funds from the banking industry into mutual funds or other investment products
which tend to offer higher returns. In addition, competitive pressures from
within the banking and savings and loan industries to increase market share are
making it much more difficult to retain deposits. To address these competitive
pressures, in 1998 the Company continued to evaluate its branch network and
alternative delivery channels in order to improve the delivery of its products
and services. As a result, the hours of operation offered to the Company's
customer base were expanded at branch offices. In addition, the Company's
automated 24-hour-a-day telephone response system and automated bill payment
system saw continued growth in transaction volumes. Two new value-added checking
accounts introduced in the fourth quarter of 1997 to meet the needs of today's
value conscious customer continued to add to the Company's customer base during
1998 and provides cross sale opportunities and increased fee income. In August
1998, the Company introduced ExecuBank, a new interactive cash management system
that allows our commercial customers access to their accounts 24 hours a day, 7
days a week from their own office via a personal computer. It is imperative that
the Company offer the products that our customers want at competitive prices and
that we continue to provide the quality service that distinguishes Mahoning
National from its peers.

The Company's repurchase agreements, which include Corporate Investment
Accounts, continued to grow in 1998. While actual balances at December 31, 1998
were $101 thousand less than December 31, 1997 balances, average balances for
1998 increased $3.681 million over 1997 average balances. The Company's
Corporate Investment account is an overnight "sweep" repurchase agreement which
is used by large corporate customers and local political subdivisions. While
these types of accounts are considered more volatile than traditional deposit
liabilities, management believes they provide a strong base of funds, which
allows the Company to support loan growth and expand its investment security
portfolio. Corporate Investment accounts are expected to remain a stable source
of funds for the Company in 1999 as existing relationships expand and new
customers are solicited.


Stockholders' Equity

Total stockholders' equity grew $9.720 million or 11% to a record high of
$96.299 million in 1998. This increase reflects retained earnings less dividends
paid and also reflects a $2.422 million unrealized gain, net of deferred taxes,
on the available for sale investment portfolio during 1998, which is a component
of equity. The stockholders' equity-to-asset ratio of 11.68% and 10.86% for 1998
and 1997 respectively, continues to remain strong when compared to industry
standards.

Under regulations issued by federal banking agencies, banks and bank holding
companies are required to maintain certain minimum capital ratios known as the
risk-based capital ratio and the leverage ratio. At December 31, 1998 the
Company's leverage, Tier 1 and total risk-based 

21
<PAGE>   24
                                              Management's Discussion & Analysis

capital ratios were 11.78%, 18.91% and 20.16%, respectively compared to 11.05%,
17.70% and 18.95% at December 31, 1997, respectively. The Company has exceeded
all required regulatory capital ratios for each period presented and is
considered "well capitalized" under all federal banking agency regulations. The
Company's risk-based capital ratios are well above the regulatory minimums due
to the capital strength and low risk nature of the balance sheet and off-balance
sheet commitments. The structure of the Company's balance sheet is such that
nearly all of the investment portfolio is invested in U.S. Government
obligations or other low risk categories, and over 20% of the loan portfolio is
invested in one-to-four family residential mortgage loans which have a 50% risk
weight assessment. Due to the increased level of capital in 1999, management is
reviewing various capital management strategies. It is the Company's intent to
prudently manage the capital base in an effort to increase return on equity
performance while maintaining the necessary capital requirements to maintain the
"well capitalized" classification. For additional information on the Company's
risk-based capital ratios and equity transactions refer to Note L-Stockholders'
Equity on pages 11 and 12 of this report.

The 24% dividend increase, from $.21 per share to $.26 per share in the fourth
quarter of 1998 represented the thirty-third consecutive year the Company has
increased the annual dividend. Dividends paid in 1998 amounted to $5.607 million
or $.89 per share compared to $4.347 million or $.69 per share in 1997 and
$3.559 million or $.565 per share in 1996. The Company's dividend payout ratio
increased for the fourth consecutive year to 40.45% for 1998 from 33.59% in 1997
and 30.66% in 1996. The book value per share as of December 31, 1998 reached a
record high of $15.29 compared to $13.74 and $12.24 at year-end 1997 and 1996,
respectively.

Asset Quality

     Provision For Loan Losses:
     --------------------------
The policies of the Company provide for loan loss reserves to adequately protect
the Company against reasonably probable loan losses consistent with sound and
prudent banking practices. In determining the monthly provision for loan losses
and the adequacy of the loan loss reserve, management reviews the current and
forecasted economic conditions and portfolio trends. The primary focus is placed
on current problem loans, delinquencies and anticipated charge-offs. As of
December 31, 1998, all loans classified for regulatory purposes do not represent
or result from trends or uncertainties which management reasonably expects will
materially impact future operating results, liquidity or capital resources.

The following exhibits show the allocation of the allowance for loan losses to
the various risk categories of the loan portfolio and a five year history of the
allowance.

The provision for loan losses charged to expense for the year-ended December 31,
1998 was $2.904 million, representing a 2% decrease from the $2.975 million
provision charged to expense in 1997 and an 11% increase over the $2.625 million
provision charged to expense in 1996. In the three year period ended December
31, 1998, the increase in provision charged to expense was due in part to growth
of the overall loan portfolio and in response to certain credits and general
economic uncertainties.

Net charge-offs declined $924 thousand or 26% from $3.563 million in 1997 to
$2.639 million in 1998. Net charge-offs as a percent of average loans were
0.54%, 0.73% and 0.35% for 1998, 1997 and 1996, respectively.

The Company's experience in 1998 and 1997 followed national trends of
deteriorating credit quality in consumer loans and credit card and related plans
brought on by the high level of consumer debt and record personal bankruptcy
filings. Net charge-offs of consumer loans and credit card and related plans
totaled $1.733 million in 1998 compared to $1.828 million in 1997 and $1.719
million in 1996.

A complete analysis of the loan underwriting and loan collection departments was
performed throughout 1997. As a result of this analysis, management established
more strict underwriting guidelines along with more proactive collection
efforts. These changes had a positive impact in 1998 as net charge-offs on
consumer loans and credit card related plans decreased by $95 thousand. As of
December 31, 1998 consumer loan delinquencies showed significant improvement
over the delinquencies at December 31, 1997. In addition, the number of
bankruptcy notices received and automobile repossessions were down 18% and 24%,
respectively for 1998 compared to 1997. This area will continue to be monitored
closely during the coming year as the Company continues to evaluate the adequacy
of the allowance for loan losses with

future provisions to the allowance being dependent upon the growth and quality
of the loan portfolio. The area's largest employer, General Motors' Lordstown,
is currently in negotiations with General Motors (GM) to secure production of
the auto maker's Delta car, scheduled to begin in 2003. The Lordstown plant
currently produces GM's J car, Chevrolet Cavaliers, Pontiac Sunfires and Toyota
Cavaliers, which will cease production with the 2002 model. The local economy
could be significantly impacted if Lordstown were not successful in obtaining
the Delta car project. As a result of possible changes in economic conditions,
there can be no guarantee that the level of the provision or allowance for loan
losses will not be increased by the Company.

The charge-offs detailed in the five year Allowance for Possible Loan Losses
schedule represent loans fully or partially charged off where the ultimate
amount to be collected was deemed to be uncertain at the time of charge-off. It
is anticipated that some of the amounts charged off will be collected in the
future and will be added to the allowance for loan losses. The timing and the
amounts of these collections are uncertain at this time.

     Nonperforming Assets:
     ---------------------
It is the Company's objective to maintain above average asset quality of its
loan portfolio through conservative lending policies and prudent underwriting.
Detailed reviews of the loan portfolio are undertaken regularly to identify
probable problem loans or trends early and to provide for adequate estimates of
probable losses. The Company normally considers loans to be nonperforming when
payments are 90 days or more past due or when the loan review analysis indicates
that repossession of the collateral may be necessary to satisfy the loan. In
addition, loans are considered to be impaired when, in management's opinion, it
is probable that the borrower will be unable to meet the contractual terms of
the loan. Nonperforming loans totaled $1.693 million at December 31, 1998, a
$1.188 million decrease from the December 31, 1997 total of $2.881 million.

Nonaccrual loans of $1.075 million at December 31, 1998 were $1.152 million less
than December 31, 1997 nonaccrual balances of $2.227 million. At December 31,
1998, commercial, residential real estate and consumer loan nonaccruals
decreased by $782 thousand, $277 thousand and $172 thousand, respectively from
nonaccrual loan totals at December 31, 1997. These nonaccrual loans are in
various stages of collection and significant principal losses are not
anticipated due to their underlying collateral values.

The following schedule is a five year summary of nonaccrual, past due and
restructured loans and other real estate owned of the Company.

Other Real Estate Owned ("OREO") represents properties acquired through
foreclosure or acceptances of deeds in lieu of foreclosure. At December 31, 1998
the Company had no OREO compared to $1.112 million at December 31, 1997. The
disposal of OREO property during 1998 increased other operating expense by $242
thousand.

The Company's nonperforming loans to allowance for loan loss ratio of 21.73% and
nonperforming loans to total loan ratio of 0.34% decreased significantly in 1998
and are currently well below peer levels of 48.37% and 0.80%, respectively. The
allowance for loan losses to total loans ratio increased from 1.53% at December
31, 1997 to 1.59% at December 31, 1998, and is approximately six basis points
below peer.


Earnings Review for the Years Ended December 31, 1998 and 1997

For the eighth consecutive year, the Company achieved record earnings. Net
income for 1998 was $13.863 million or $2.20 per share, an increase of $922
thousand or 7% over 1997 earnings of $12.941 million or $2.05 per share.

The primary component of the Company's earnings growth in 1998 was net interest
income which was primarily due to a reduction in funding costs. Net interest
income and noninterest income, exclusive of security transactions, increased 5%
and 7%, respectively in 1998 compared to 1997, while the provision for loan
losses declined 2%. Noninterest expense increased 4% over that same period.

The prime interest rate, which had been at 8.50% from March 1997 until October
1998, declined to 7.75% at December 31, 1998. In the fourth quarter of 1998 the
Federal Reserve Bank took the following actions: (1) October 1, 1998, lowered
the federal funds rate by 25 basis points, (2) October 16, 1998, lowered the
federal funds rate an additional 25 basis points and reduced the discount rate
by 25 basis points and (3) November 17, 1998, lowered the federal funds rate and
discount rate an additional 25 basis points. As a result of these Federal
Reserve rate adjustments, the Company reduced its prime lending rate by 75 basis
points in the fourth quarter to 7.75%. As the Company's interest rate
simulations and net economic value analysis indicated these rate reductions had
a positive impact on net interest income in the fourth quarter of 1998. Due to
the liability sensitive nature of the Company's balance sheet, rate reductions
in the fourth quarter of 1998 are expected to positively impact net interest
income in 1999. With declining interest rates in 1998, the Company's net
interest margin increased to 4.89% from 4.79% in 1997.

The Company's return on assets (ROA) for 1998 increased to 1.74% from 1.67% in
1997. As a result of the Company's significant growth in equity in 1998, $9.720
million, return on average stockholders' equity (ROE) declined to 15.12% in 1998
from 15.82% in 1997. The Company's stockholders' equity to asset ratio increased
to 11.68% in 1998 from 10.86% in 1997.

As of December 31, 1998, the Company was not aware of any recommendations by the
regulatory authorities which, if implemented, would have a material effect on
the Company's liquidity, capital resources or operations.


Net Interest Income

Net interest income is the primary component of the Company's earnings and is
the difference between interest and fees earned on loans, investments and other
interest earning assets and the interest expense on deposits and other interest
bearing liabilities which fund those assets.

The Company's return on interest earning assets decreased from 8.03% in 1997 to
7.91% in 1998 while funding costs decreased from 3.84% in 1997 to 3.64% in 1998.

asset balances and reduced funding costs accounted for the increase in net
interest income in 1998.

Net interest income was $35.990 million for 1998, an increase of 5% over 1997
net interest income of $34.369 million. In 1998, the most significant factors
for the increase in net interest income were reduced funding costs and volume
increases in the investment portfolio. The Company's investment portfolio
average balance, which increased by $17.877 million in 1998, contributed an
additional $905 thousand in tax adjusted interest income in 1998. With average
loan balances increasing only $2.199 million in 1998 over 1997, the impact of
the lower loan portfolio yield, a $551 thousand reduction of tax adjusted net
interest income, more than offset volume related increases of $189 thousand. The
increase in the Company's tax adjusted net interest income as a result of
changes in volume amounted to $812 thousand compared to $872 thousand in 1997.
The increase in tax adjusted net interest income due to rate was $830 thousand
in 1998 compared to $351 thousand in 1997. The reduction in interest expense due
to rate totaled $1.399 million in 1998 compared to $205 thousand in 1997.

The tax equivalent yield of the loan portfolio for 1998 decreased to 8.87% from
8.98% in 1997, a result of the decrease in the prime lending rate of 75 basis
points in the fourth quarter of 1998, a reduction in loan fees and competitive
market pressures. These issues will continue to impact loan growth and portfolio
yield throughout 1999. The loan to deposit ratio at December 31, 1998 and 1997
was 88.36% and 90.35%, respectively.

Average interest bearing liabilities grew slightly in 1998 to $624.439 million
from $619.591 million in 1997. The cost of interest bearing liabilities
decreased to 3.64% in 1998 from 3.84% in 1997. This reduction in funding costs
is primarily due to the Company reducing its average savings, interest bearing
checking and time deposit rates by 25, 29 and 17 basis points, respectively in
1998. The reduction in deposit rates, which reduced interest expense by $1.060
million in 1998, was partially offset by a $419 thousand increase in interest
expense due to volume increases in long term borrowings. This lower cost of
funds should continue to positively impact net interest income in 1999 as many
of the rate reductions were implemented in the fourth quarter of 1998 in
response to the Federal Reserve rate reductions.

Change in Net Interest Income Due to Volume and Rate

The following table represents an analysis of the chages in tax-equivalent net interest income for the prior two year
period. These changes to net interest income were the result of changes in the volume and mix of earning assets and

Other Operating Revenue

Other operating revenue of $8.731 million, exclusive of security transactions,
increased $580 thousand, or 7.1%, over 1997. The largest component of other
operating revenue in 1998 was service charges on deposit accounts which
increased $113 thousand, or 2.7%, over 1997. Other operating revenue, exclusive
of security transactions, as a percent of average assets was 1.10% in 1998
compared to 1.05% in 1997. The Company annually reviews all of its fee-based
products and services for marketability and profitability. Increases realized in
1998 were the result of growth in the number of retail checking accounts over
the past fifteen months which coincided with the introduction of two new
checking account products. The Company expects service charges on deposit
accounts to increase due to planned fee increases in 1999. Service charges on
deposit accounts as a percent of average deposits increased to .79% in 1998 from
 .77% in 1997.

Mahoning National Bank's Trust and Investments Department generated $3.019
million in other operating revenue in 1998, a $155 thousand or 5.4% increase
over the $2.864 million earned in 1997. Trust Department assets totaled $477.406
million in book value with a market value of $729.166 million at December 31,
1998 compared to $438.456 million in book value with a market value of $641.560
million at December 31, 1997. This increase in assets was the result of growth
in personal trust, custody and investment accounts. The $155 thousand increase
in trust fees can be attributed to several factors: department growth, an
increase in asset market values on which the fees are based, an improved mix of
higher fee paying accounts and increased executorship fees.

In 1998, the Company became more active in the origination and sale of
residential mortgages in the secondary market. These sales generated $326
thousand in gains compared to $19 thousand in 1997. The Company expects to
continue secondary market sales in 1999.

In 1998, the Company realized a $229 thousand gain on sale of investment
securities available for sale compared to a $182 thousand gain in 1997.


Other Operating Expense

Other operating expense of $21.417 million increased $791 thousand, or 3.8%,
during 1998. This followed a $129 thousand, or 0.6%, increase in 1997. As a
percentage of average assets, other operating expense was 2.69% in 1998 compared
to 2.66% in 1997. The Company's efficiency ratio, which measures noninterest
expense as a percent of noninterest income plus net interest income on a fully
tax equivalent basis, improved by 32 basis points from 47.71% in 1997 to 47.39%
in 1998. This efficiency ratio places the Company near the top of its peer
group.

In 1998, total salaries and employee benefit expense decreased $53 thousand,
from 1997. In 1998, salary expense alone increased $215 thousand, or 2.3%,
compared to an increase of $211 thousand, or 2.3%, in 1997. This increase can be
attributed to annual merit salary adjustments which took effect January 1, 1998.
Health care expenses for 1998 and 1997 were $756 thousand and $755 thousand,
respectively. The number of full-time equivalent employees decreased from 388 at
December 31, 1997 to 375 at December 31, 1998. Additional employee benefit
savings of $181 thousand were realized as a result of reduced pension and
Workmen's Compensation costs in 1998.

Net occupancy expense, which represents various facility management expenses,
increased $14 thousand in 1998 to $1.476 million from $1.462 million in 1997. In
December 1998, the Company opened a new free-standing branch in Austintown to
replace the previous plaza location. In January 1999, two additional branches
will be consolidated into this location. Expenses to close the existing offices
into the new facility were not material and the consolidation is expected to
begin reducing overhead expenses in 1999.

Other expenses increased $814 thousand in 1998 to $6.499 million from $5.685
million in 1997, a 14.3% increase. This increase was the result of increased
expenses associated with the disposal of other real estate

owned, increased amortization and support of software purchased in 1998 and
1997, branch consolidations and corporate donations along with increased
business activity and general inflationary increases.

Year 2000

In early 1997, the Company began to address the Year 2000 issue, which covers
the process of converting computer systems to identify the Year 2000. A Year
2000 Committee was formed consisting of senior management and selected
representatives from all areas of the Company, with a senior officer appointed
as the project manager. It is the project manager's responsibility to provide
the Board of Directors with quarterly status reports, detailing the Company's
internal Year 2000 corrective efforts and the ability of the Company's major
vendors to provide Year 2000 ready products and services. The reports include,
at a minimum, the overall progress of the Year 2000 compliance effort, including
new efforts initiated since the last report, the Company's progress as compared
to its overall Year 2000 project plan and critical benchmarks, status reports
regarding vendors, business partners, major loan customers, results of internal
and external testing and contingency planning.

The Year 2000 Committee identified information technology and noninformation
technology applications and systems that could be impacted by the Year 2000 date
change and identified any third-party vendors that impact the daily operation of
the Company. Those applications, systems and vendors that the Company identified
as mission critical were prioritized based on their potential impact to the
ongoing operation of the Company. An application, system or vendor is considered
mission critical if it is vital to the successful continuance of core business
activity or is an application that interfaces with a mission critical system.

A project plan has been developed based on the five (5) phases outlined by the
Federal Financial Institutions Examination Council (FFIEC): Awareness,
Assessment, Renovation, Validation and Implementation. The Awareness Phase
encompasses establishing a budget and project plan for dealing with the Year
2000 issue. The Assessment Phase is the actual process of identifying and
preparing an inventory of all its systems and individual components of those
systems. During this phase, all system components were reviewed for Year 2000
compliance, and through a risk analysis process were identified as to whether
they were mission critical. The Renovation Phase is when changes are made to
systems. This phase deals primarily with the technical issues of converting
existing systems, or switching to compliant systems. During this phase,
decisions are made on how to make the systems or processes Year 2000 compliant,
and the required system changes are made. The Validation Phase is when a
determination is made that no errors were introduced during the conversion
process and that the renovation was successful. The development of test data and
test scripts, the running of test scripts and the review of test results are
crucial for this phase of the conversion process to be successful. If testing
results show anomalies, the testing area is corrected and retested. The
Implementation Phase is when a tested Year 2000 compliant system is ready for
use. At the end of September 1998, the Awareness and Assessment phases had been
completed and documentation supporting the comprehensive Year 2000 project plan
was completed. The Company is currently at various stages of the Renovation,
Validation and Implementation phases on those applications or systems identified
as mission critical to the Company. The Company has renovated all of its mission
critical applications and systems except for three which are expected to be
completed by March 31, 1999. The Company expects to complete the Validation and
Implementation phases on the remaining applications and systems identified as
mission critical by March 31, 1999.

During the first quarter of 1998, the Company initiated a vendor management
process that ascertains the Year 2000 readiness of third- party relationships.
The Company has established monitoring procedures to verify the service provider
and/or software vendor is taking appropriate action to achieve Year 2000
readiness. In addition, the Company has established a process for testing
remediated services and products in the Company's own environment whenever
possible. At this point in time, the greatest concern the Company has with
third-parties is with the possible interruption of electrical power, which is
certainly a concern that all businesses face due to the interdependencies within
the nation's power grid. The Company has evaluated alternatives and has
developed procedures to operate in the event there are interruptions to the
electrical power supply.

Remediation contingency plans have been developed and alternative vendors
identified for each issue listed as mission critical. These plans include
various dates, which if certain requirements have not been met by current
vendors to validate their Year 2000 readiness, will require a switch to an
alternative vendor identified as Year 2000 compliant. The Company has developed
a Business Resumption Contingency Plan for the Year 2000 in order to mitigate
the risks associated with; (1) The failure to successfully complete renovation,
validation, or implementation of the Company's Remediation Contingency Plan, and
(2) Failure of systems at critical dates. In Business Resumption Contingency
Planning, risks associated with the failure of core business processes are
evaluated. These are groups of related tasks that must be performed in a
cohesive manner to ensure that the Company remains viable. Evaluation of these
risks compare costs, time and resources needed to implement the contingency
alternatives. The Business Resumption Contingency Plan is not static in nature,
and will evolve as the Company progresses into 1999.

The estimated cost for the Company's Year 2000 Remediation project is
approximately $765 thousand. These costs include various hardware and software
purchases and modification, employee training, professional services and
additional employee man hours. Through December 31, 1998, approximately $238
thousand has been expensed on Year 2000 Remediation with the remaining expense
expected to occur over the next 15 months.

An additional area under review by the Company is the Year 2000 risk arising
from relationships with three broad categories of customers: fund takers
(borrowers), fund providers (depositors), and capital market/asset management
counterparties (brokers). The potential risks associated with these customers
and counterparties include increased credit, liquidity or counterparty trading
risk when a customer encounters Year 2000 related problems. The Company has
implemented a due diligence process that has identified, assessed and
established controls for Year 2000 risk by customers. This process was completed
by September 30, 1998, with appropriate risk controls in place to manage and
mitigate Year 2000 customer risk. The Company will continue this due diligence
process throughout 1999.


Income Taxes

Income tax expense for 1998 was $6.766 million compared to $6.160 million in
1997. The Company's effective tax rates were 32.8% and 32.2% for 1998 and 1997,
respectively, compared to the statutory federal income tax rate of 35%. Tax
exempt investment and loan income is the primary reason the Company's effective
tax rate is less than the statutory tax rate.

The components of the Company's deferred income tax asset and reconciliation of
the effective tax rate can be found on page 10 of this report. (Note I - Income

Earnings Review for the Years Ended
December 31, 1997 and 1996

     Net Income:
     -----------
Net income for 1997 was $12.941 million or $2.05 per share, an increase of
$1.330 million or 11% over 1996 earnings of $11.611 million or $1.84 per share.
The Company's return on assets (ROA) for 1997 increased to 1.67% from 1.55% in
1996. The return on average stockholders' equity (ROE) for 1997 was 15.82%,
compared to 15.83% in 1996. The Company was able to maintain its return on
equity while increasing its stockholders' equity to asset ratio to 10.86% in
1997 from 10.02% in 1996. The primary component of the Company's earnings growth
in 1997 was net interest income, and the significant growth in the loan
portfolio was the primary reason for that earnings increase.

     Net Interest Income:
     --------------------
Net interest income was $34.369 million for 1997, an increase of 4% over 1996
net interest income of $33.099 million. In 1997, the most significant factor for
the increase in net interest income was loan volume. This accounted for
additional tax adjusted interest income of $1.067 million, as average balances
grew by $11.930 million during 1997. The Company's investment portfolio average
balance, which increased by $10.772 million in 1997, contributed to a $675
thousand increase in tax adjusted interest income compared to an increase of
$244 thousand in 1996. The increase in the Company's tax adjusted net interest
income as a result of changes in volume amounted to $871 thousand compared to
$1.759 million in 1996. The decline in the volume related impact to net interest
income is the result of average loan balances increasing only $11.930 million in
1997 over 1996, compared to a $32.643 million increase in average loan balances
in 1996 over 1995. Average interest earning assets for 1997 were $733.636
million, or 3.5% greater than the $708.869 million of earning assets in 1996.
The increase in tax adjusted net interest income due to rate was $351 thousand
in 1997, compared to $442 thousand in 1996.

The tax equivalent yield on the loan portfolio for 1997 increased to 8.98%
compared to 8.93% in 1996, a result of the prime lending rate increasing by 25
basis points in March 1997, changes in the portfolio mix and increases in loan
fees. The loan to deposit ratio at December 31, 1997 and 1996 was 90.35% and
86.71%, respectively.

Average interest bearing liabilities for 1997 were $619.591 million, or 2.4%
greater than the $605.325 million of average interest bearing liabilities in
1996. The cost of interest bearing liabilities increased slightly to 3.84% in
1997 from 3.80% in 1996. While actual December 31, 1997 deposit balances
declined only $5.887 million from December 31, 1996 balances, average balances
declined $23.753 million in 1997 from 1996 average balances. This loss in
deposits was more than offset by an increase in the volume of securities sold
under agreements to repurchase as more corporate and political subdivisions
placed their funds into overnight "sweep" repurchase agreements. The average
balance of these interest bearing liabilities increased $35.033 million in 1997
and the cost of these funds increased by 16 basis points from 1996. Actual
year-end balances for 1997 were up $23.778 million over 1996 year-end balances.
The prime interest rate, which declined from 8.50% to 8.25% in February 1996,
increased 25 basis points in March 1997, back to 8.50% where it remained
throughout the year. With interest rates stable over 1997 and 1996, the
Company's net interest margin was also stable at 4.79% and 4.78% for 1997 and
1996, respectively. The growth in earning assets in 1997 helped offset increased
funding costs.

     Other Operating Revenue:
     ------------------------
Other operating revenue of $8.151 million, exclusive of security transactions,
increased $658 thousand, or 8.8%, over 1996. The largest component of other
operating revenue in 1997 was service charges on deposit accounts which
increased $538 thousand, or 14.8%, over 1996. Other operating revenue, exclusive
of security transactions, as a percent of average assets was 1.05% in 1997
compared to 1.00% in 1996. Adjustments to fees for the Company's products and
services and the strengthening of controls for the collection of such fees were
the reasons for the significant increase. In 1997, service charges on deposit
accounts as a percentage of average deposits increased to .77% from .64% in
1996.

Mahoning National Bank's Trust and Investments Department generated $2.864
million in other operating revenue in 1997, approximately the same amount as the
$2.837 million earned in 1996. Trust Department assets totaled $438.456 million
with a market value of $641.560 million at December 31, 1997, compared to
$575.712 million with a market value of $775.688 million at December 31, 1996.
This decrease was the result of a corporate customer consolidating employee
benefit and custody trust accounts with a financial institution outside of our
market area in the second quarter of 1997. The $27 thousand increase in trust
fees, even with the loss of this large corporate customer, can be attributed to
the department's market based fees, which increased due to the significant
increase in account market values as a result of rises in the stock market over
1996.

In 1997, the Company realized $182 thousand in gains when $20.075 million of
U.S. government securities coming due in 1997 and $2.167 million of nontaxable
municipals were sold from the available for sale portfolio and reinvested in
longer term U.S. Treasury securities and nontaxable municipals. This compared to
a loss of $319 thousand in 1996, when $24.658 million of U.S. government
securities were sold from the available for sale portfolio and reinvested into
longer term U.S. Treasury securities.

     Other Operating Expense:
     ------------------------
Other operating expense of $20.626 million increased $129 thousand, or 0.6%,
during 1997. This followed a $117 thousand, or 0.6%, increase in 1996. As a
percentage of average assets, other operating expense was 2.66% in 1997 compared
to 2.73% in 1996. The Company's efficiency ratio which measures noninterest
expense as a percent of noninterest income plus net interest income on a fully
tax equivalent basis declined 191 basis points from 49.62% in 1996 to 47.71% in
1997. This efficiency ratio placed the Company near the top of its peer group.

In 1997, total salaries and employee benefit expense increased $330 thousand, or
3.1%, from 1996. Salary expense for 1997 alone increased $211 thousand, or 2.3%,
compared to an increase of $699 thousand, or 8.4%, in 1996. This increase was
attributed to annual merit salary adjustments which took effect January 1, 1997,
and increases in various employee incentive programs. In 1996, as a result of
departmental restructuring and selective staff reductions, a one-time charge of
approximately $342 thousand was charged to salary expense. This charge increased
1996 salary expense but provided for long term salary cost savings. Health care
expenses for 1997 were $755 thousand compared to $585 thousand for the same
period in 1996, an increase of $170 thousand or 29%. This increase was due in
part to increased health care claims in 1997 and increased premium rates on the
Company's health care plans. The number of full-time equivalent employees
decreased from 391 at December 31, 1996 to 388 at December 31, 1997.

Net occupancy expense, which represents various facility management expenses,
decreased $23 thousand in 1997 to $1.462 million from $1.485 million in 1996.
These decreases were the result of reduced building maintenance and utility
expenses.

Equipment rental, depreciation and maintenance of $1.432 million decreased $295
thousand, or 17.1% from 1996. This decrease was the result of the termination of
various computer equipment leases and their related service contracts. The
equipment that was covered by these leases was either purchased at a discount or
disposed.

Other expenses increased $149 thousand in 1997, to $5.615 million from $5.466
million in 1996, a 2.7% increase. This increase was the result of amortization
and support on software purchased in 1996 and 1997, increased marketing expenses
related to the promotion of loan and deposit products, increased business
activity and general inflationary increases.

     Income Taxes:
     -------------
Income tax expense for 1997 was $6.160 million compared with $5.540 million in
1996. The Company's effective tax rates were 32.2% and 32.3% for 1997 and 1996,
respectively, in comparison to the statutory federal income tax rate of 35%. Tax
exempt investment and loan income is the primary reason the Company's effective
tax rate is less than the statutory tax rate.

Liquidity

It is a primary objective of the Company to maintain a level of liquidity deemed
adequate to meet the expected and potential funding needs of loan and deposit
customers. It is the Company's policy to manage its affairs so that liquidity
needs are fully satisfied through normal bank operations. Short term investments
(Federal funds sold) and short term borrowings (Federal funds purchased,
repurchase agreements, U.S. Treasury demand notes and Federal Home Loan Bank
advances) are used as primary cash management and liquidity tools. Short term
Federal fund lines totaling $60 million have been established at the Company's
correspondent banks. When loan demand increases at a faster rate than deposit
growth, it may be necessary to manage the available for sale portion of the
investment portfolio to meet that demand, or to sell conforming residential
mortgages on the secondary market. At December 31, 1998 and 1997, $3.275 million
and $298 thousand of residential mortgage loans were designated as held for
sale. At December 31, 1998, $241.037 million of the investment portfolio was
classified as available for sale. This classification will afford the Company's
Asset/Liability Committee the flexibility to manage the portfolio to meet any
liquidity needs that may arise.

An additional source of liquidity is derived from the Federal Home Loan Bank of
Cincinnati (FHLB). The FHLB provides short term funding alternatives with a
remaining available borrowing of $38.793 million and funding for one-to-four
family residential mortgage loans and allows the Company to better manage its
interest rate risk. The Company had $17.191 million outstanding in FHLB
borrowings at December 31, 1998, compared to $3.151 million outstanding at
December 31, 1997.

Mahoning National has been serving the Mahoning Valley for 130 years and has
developed a solid core deposit base. Of the $555.407 million in deposits on
December 31, 1998, only $33.891 million represent time deposits in excess of
$100 thousand. Even though these deposits which exceed $100 thousand are not
considered core deposits due to their volatile nature, the Company's core
deposit to total asset ratio is still strong at 63%. With the Company's strong
core deposit base, growth in corporate investment accounts and access to
funding, the liquidity position of the Company is such that there is still an
unused capacity to fund loans. At December 31, 1998, and throughout the past
twelve months, key liquidity ratios were within established Company and
regulatory guidelines.

The maturity distribution of the Company's total time deposits in amounts of
$100 thousand or greater as of December 31, 1998, is summarized below:

Impact of Inflation and Changing Prices

The financial statements and related data presented herein have been prepared in
accordance with generally accepted accounting principles, which require the
measurement of financial position and results of operations primarily in terms
of historical dollars without considering changes in the relative purchasing
power of money over time due to inflation. Unlike most industrial companies,
virtually all of the assets and liabilities of the Company are monetary in
nature. Therefore, interest rates have a more significant impact on a financial
institution's performance than the effects of general levels of inflation.
Interest rates do not necessarily move in the same direction or in the same
magnitude as the prices of goods and services. The liquidity, maturity structure
and quality of the Company's assets and liabilities are critical to the
maintenance of acceptable performance levels.


Quantitative and Qualitative Disclosures about Market Risk

The primary objective of the Company's asset/liability management process is to
maximize profits through management of the pricing and mix of assets and
liabilities, while achieving acceptable levels of interest rate risk and
liquidity risk and providing for adequate capitalization. Since assets and
liabilities of a financial institution are monetary in nature, changes in
interest rates and monetary or fiscal policy affect its financial condition and
have potentially the greatest impact on the net income of the Company. The
Company's asset/liability management program is designed to minimize the impact
of sudden and sustained changes in interest rates on the net present value (NPV)
of equity and net interest income.

The Company's primary market risk exposure is interest rate risk and, to a
lesser extent, liquidity risk. All of the Company's transactions are denominated
in U.S. dollars with no specific foreign exchange exposure. The Company has
minimal agricultural loan assets and therefore would not have a specific
exposure to changes in commodity prices. The Company has no market risk
sensitive instruments held for trading purposes.

As part of its effort to monitor and manage interest rate risk, the Company uses
simulation analysis and net present value analysis. The simulation analysis
monitors interest rate risk through the impact changes in interest rates can
have on net income. At December 31, 1998, the Company analyzed the effect of a
presumed 100 and 200 basis point increase and decrease in interest rates through
its simulation analysis. The results indicated no significant impact on net
interest income for 1999, and were within the five percent (5%) of net interest
income guidelines established by the Company. While the results of the
simulation indicated no significant impact on net interest income over the next
twelve months, they did indicate the Company to be negatively impacted by rising
interest rates and positively impacted by falling interest rates due to the
liability sensitive nature of the balance sheet.

The NPV analysis is used to measure the Company's interest rate risk by
computing estimated changes in NPV of its cash flows from assets, liabilities
and off-balance sheet items in the event of a range of assumed


                                                                              28

                                            Management's Discussion and Analysis


changes in market interest rates. NPV represents the market value of equity and
is equal to the market value of assets minus the market value of liabilities,
with adjustments made for off-balance sheet items. This analysis assesses the
risk of loss in market risk sensitive instruments in the event of a sudden and
sustained 100 to 200 basis point increase or decrease in market interest rates.
The Board of Directors has adopted an interest rate risk policy which
establishes maximum changes in the NPV of 20% in the event of a sudden and
sustained 100 to 200 basis point increase or decrease in market interest rates.
The following table presents the Company's projected change in NPV for the
various rate shock levels at December 31, 1998. All market risk sensitive
instruments presented in this table are held to maturity or available for sale.
The Company has no trading securities.

</TABLE>

The above table indicates that at December 31, 1998, in the event of a sudden
and sustained increase in prevailing market interest rates, the Company's NPV
would be expected to decrease, and in the event of a sudden and sustained
decrease in prevailing market interest rates, the Company's NPV would be
expected to increase. At December 31, 1998, the Company's estimated changes in
NPV were within the targets established by the Board of Directors, with the
exception of the 200 basis point increase in interest rates which was marginally
above the 20% limit.

As with any method of measuring interest rate risk, certain shortcomings are
inherent in the NPV approach. For example, although certain assets and
liabilities may have similar maturities or periods of repricing, they may react
in different degrees to changes in market interest rates. Also, as a result of
competition, the interest rates on certain assets and liabilities may fluctuate
in advance of changes in market interest rates, while interest rates on other
types of assets and liabilities may lag behind changes in market rates. In the
event of a change in interest rates, expected rates of repayment on assets and
early withdrawal levels from certificates of deposit would likely deviate from
those scheduled. In addition, the proportion of adjustable rate loans in the
Bank's portfolio could decrease in future periods if market interest rates
remain at or decrease below current levels due to refinance activity. Further,
in the event of a change in interest rates, prepayment and early withdrawal
levels would likely deviate from those assumed in the table. Finally, the
ability of many borrowers to repay their adjustable rate debt may decrease in
the event of an increase in interest rates.

In order to minimize the potential for adverse effects of material and prolonged
increases in interest rates on the Company's results of operations, management
has implemented and continues to monitor asset and liability management
strategies to better match the maturities and repricing terms of the Company's
interest earning assets and interest bearing liabilities. These strategies
include: (1) Emphasizing the origination of adjustable rate mortgage loans
("ARMs"); and (2) Selling a portion of its fixed rate residential mortgage loan
origination's with servicing retained.

Deposits, which are the Company's primary funding source, are priced based upon
competitive factors and the availability of prudent lending and investment
opportunities. Pursuant to this strategy, the Company has generally not offered
the highest rates available in its deposit market except on specific occasions
and for specific products in order to control deposit flow or when market
conditions have created opportunities to attract longer term deposits at
favorable rates. In addition, the Company does not pursue an aggressive growth
strategy which would force the Company to focus exclusively on competitors'
rates rather than deposit affordability. This policy has assisted the Company in
controlling its cost of funds. The Company has also adopted a strategy of
emphasizing transaction deposit account growth as these products are less
susceptible to repricing in a rising interest rate environment.

Derivative financial instruments include futures, forwards, interest rate swaps,
option contracts and other financial instruments with similar characteristics.
The Company has not purchased derivative financial instruments in the past and
does not presently intend to purchase such instruments in the near future.
However, the Company is party to financial instruments with off-balance sheet
risk in the normal course of business to meet the financing needs of its
customers. These financial instruments include commitments to extend credit and
standby letters of credit. These instruments involve, to varying degrees,
elements of credit and interest rate risk in excess of the amount recognized in
the consolidated balance sheets. The commitments to extend credit generally have
fixed expiration dates or other termination clauses and may require payment of a
fee. Since some of these commitments may not be utilized, or utilized in amounts
less than the total committed, the total commitment amounts do not necessarily
represent future cash requirements. The majority of the unfunded commitments at
December 31, 1998 ($152 million) are variable rate commitments, with
approximately 10% or $17 million having fixed rates. Standby letters of credit
are conditional commitments issued by the Company to guarantee the performance
of a customer to a third party up to a stipulated amount and with specified
terms and conditions.

The Company's exposure to interest rate risk is reviewed on a quarterly basis by
the Board of Directors and the ALCO. If estimated changes to NPV and net
interest income are not within the limits established by the Board, the Board
may direct management to adjust its asset and liability mix to bring interest
rate risk within board approved limits.

Impact of New Accounting Standards

Recent pronouncements by the Financial Accounting Standards Board ("FASB") will
have an impact on financial statements issued in current or subsequent periods.
Set forth below are summaries of such pronouncements.

In February 1998, the FASB issued Statement of Financial Accounting Standards
(SFAS) No. 132 "Employers' Disclosures about Pensions and Other Postretirement
Benefits". SFAS No. 132 increased and revised pension plan disclosures for
public companies. The Company revised its disclosures included in the financial
statements based on the new standard.

In June 1998, the FASB issued SFAS No. 133 "Accounting for Derivative
Instruments and Hedging Activities". SFAS No. 133 addresses the accounting for
derivative instruments and certain derivative instruments embedded in other
contracts, and hedging activities. The statement standardizes the accounting for
derivative instruments by requiring that an entity recognize those items as
assets or liabilities in the statement of financial position and measure them at
fair value. This statement is effective for all fiscal years beginning after
June 15, 1999.

In October 1998, the FASB issued SFAS No. 134 "Accounting for Mortgage-Backed
Securities Retained after the Securitization of Mortgage Loans Held for Sale by
a Mortgage Banking Enterprise". SFAS No. 134 will, in 1999, allow mortgage loans
that are securitized to be classified as trading, available for sale, or in
certain circumstances held to maturity. Currently these must be classified as
trading.

These statements are not expected to have a material effect on the Company's
consolidated financial position or results of operation.

                         MAHONING NATIONAL BANCORP, INC.
                                YOUNGSTOWN, OHIO

                                 PROXY STATEMENT

                               GENERAL INFORMATION

         This Proxy Statement is furnished in connection with the solicitation
by the Board of Directors of Mahoning National Bancorp, Inc. (the "Corporation")
of proxies to be voted at the Annual Meeting of shareholders to be held on
Tuesday, March 16, 1999, in accordance with the foregoing notice.

         The Corporation is a one-bank holding company of which The Mahoning
National Bank of Youngstown (hereinafter "Mahoning National Bank") is a wholly
owned subsidiary.

         The solicitation of proxies on the enclosed form is made on behalf of
the Board of Directors of the Corporation. All cost associated with the
solicitation will be borne by the Corporation. The Corporation does not intend
to solicit proxies other than by use of the mails, but certain officers and
regular employees of the Corporation or its subsidiaries, without additional
compensation, may use their personal efforts, by telephone or otherwise, to
obtain proxies. The proxy materials are first being mailed to shareholders on
February 12, 1999.

         Any shareholder executing a proxy has the right to revoke it by the
execution of a subsequently dated proxy, by written notice delivered to the
Secretary of the Corporation prior to the exercise of the proxy or in person by
voting at the meeting. The shares will be voted in accordance with the direction
of the shareholder as specified on the proxy. In the absence of instructions,
the proxy will be voted "FOR" the election of the three (3) persons listed in
this Proxy Statement.

                                VOTING SECURITIES

         Only shareholders of record at the close of business on January 29,
1999, will be eligible to vote at the Annual Meeting or any adjournment thereof.
As of January 29, 1999, the Corporation had outstanding 6,300,000 shares of
Common Stock, no par value. Shareholders are entitled to one (1) vote for each
share of common stock owned as of the record date, and shall have the right to
cumulate votes in the election of directors, in accordance with Ohio law.
Cumulative voting permits a shareholder to multiply the number of shares held by
the number of directors to be elected, and cast those votes for one candidate or
spread those votes among several candidates as he or she deems appropriate.

         As of January 29, 1999, Mahoning National Bank held 868,993 shares of 
the Corporation's outstanding shares in their Trust Department in regular or
nominee accounts. This total represents 13.79 percent of the outstanding
shares, which will be voted in accordance with the instructions contained in
the various trust agreements pursuant to which such shares are held and may,
therefore, in certain circumstances in which discretionary voting is granted to
the trustee, be voted at the direction of The Mahoning National Bank as
Trustee.

COMMITTEES AND COMPENSATION OF THE BOARD OF DIRECTORS

         The Corporation's nominating function is performed by the Board of
Directors acting as a committee of the whole. In conducting its nominating
function, the Board of Directors of the Corporation is responsible for making
annual nominations for directors to fill vacancies created by expired terms of
directors and, from time to time, making appointments to fill vacancies created
prior to the expiration of a director's term. During 1998, the Board met once to
consider and act upon the nomination of directors.

         During 1997 the Company established an Examining Committee which
performs the functions of an Audit Committee. The Examining Committee's
functions include its obligation to: (a) annually recommend to the Board of
Directors of the Company, and to the Board of Directors of each of the Company's
subsidiaries, for appointment by the respective boards, independent public
accountants as auditor of the books, records and accounts of the Company and
each such subsidiary; (b) review the scope of audits made by the independent
public accountants; and (c) receive and review the audit reports submitted by
the independent public accountants and take such action in respect of such
reports as the Examining Committee may deem appropriate. During 1998 the
Examining Committee of the Bank performed the functions of the Company's
Examining Committee and met four times.

</TABLE>

         A participant's remuneration covered by the Corporation's pension plan
is his or her average salary (as reported in the Summary Compensation Table) for
the 60 months before normal retirement. Participants are vested in their pension
benefits after five years of service. Mr. McHenry had 9 years of service, Mr.
Ridler had 28 years of service, Mr. Hierro had 13 years of service and Mr.
Westerburg had 5 years of service, respectively, as of December 31, 1998.

         Effective on December 11, 1995, the Corporation entered into a
Supplemental Executive Retirement Plan with Mr. Ridler. The purpose of the Plan
is to replace certain retirement benefits which Mr. Ridler lost under the
Corporation's qualified retirement plans due to the eligible compensation
limitations under current tax law. Pursuant to the terms of the Supplemental
Executive Retirement Plan, upon Mr. Ridler's retirement at his Normal Retirement
Age of 65, he will receive payments of $93,000 from the Corporation, annually,
for twenty years. This amount represents an estimate of the value of the lost
benefits resulting from the reduction in eligible compensation under the
Corporation's tax qualified retirement plan. Reduced benefits are provided to
Mr. Ridler under the Supplemental Executive Retirement Plan in the event of
early retirement.

         In addition, contemporaneously with the adoption of the Supplemental
Executive Retirement Plan, the Corporation and Mr. Ridler entered into a Split
Dollar Life Insurance Agreement which provides for the payment, to Mr. Ridler's
beneficiaries, of one-third of the net-at-risk insurance portion of an insurance
policy purchased by the Corporation in connection with the establishment of the
Supplemental Executive Retirement Plan. As of December 31, 1998, this Split
Dollar Life Insurance Agreement would have provided a death benefit of $357,107
to Mr. Ridler's beneficiaries. The Corporation purchased life insurance for the
purpose of funding its obligations under the Supplemental Executive Retirement
Plan in the event of Mr. Ridler's death and as an investment vehicle designed to
fund the payments to Mr. Ridler at retirement.

REPORT OF THE EXECUTIVE COMMITTEE OF THE MAHONING NATIONAL BANK ON COMPENSATION

         Under rules established by the Securities and Exchange Commission (the
"SEC"), the Corporation is required to provide certain data and information in
regard to the compensation and benefits provided to the Corporation's Chairman
of the Board, President and Chief Executive Officer and, if applicable, the four
other most highly compensated executive officers, whose compensation exceeded
$100,000 during the Corporation's fiscal year. The disclosure requirements, as
applied to the Corporation, includes the Corporation's Chairman of the Board,
President and Chief Executive Officer (Mr. Gregory L. Ridler), Executive Vice
President (Mr. Parker T. McHenry), and Senior Vice President, Loans (Mr. Frank
Hierro), and Senior Vice President, Operations/Retail Banking (Mr. David E.
Westerburg) and includes the use of tables and a report explaining the rationale
and considerations that led to fundamental executive compensation decisions
affecting Mr. Ridler, Mr. McHenry, Mr. Hierro and Mr. Westerburg. The
Corporation is a holding company and owns a single subsidiary, The Mahoning
National Bank. The Corporation has no direct employees. All disclosures
contained in this Proxy Statement regarding executive compensation reflect
compensation paid by The Mahoning National Bank. The Executive Committee of The
Mahoning National Bank (the "Committee") has the responsibility of determining
the compensation policy and practices with respect to all Executive Officers. At
the direction of the Board of Directors, the Committee has prepared the
following report for inclusion in this Proxy Statement.

         COMPENSATION PHILOSOPHY. This report reflects the Corporation's
compensation philosophy as endorsed by the Committee. The Committee determines
the level of compensation for all other executive officers within the
constraints of the amounts approved by the Board.

         Essentially, the executive compensation program of the Corporation has
been designed to:

- -        Support a pay-for-performance policy that awards executive officers for
         corporate performance.

- -        Motivate key senior officers to achieve strategic business goals.

- -        Provide compensation opportunities which are comparable to those
         offered by other peer group companies, thus allowing the Corporation to
         compete for and retain talented executives who are critical to the
         Corporation's long-term success.

         SALARIES. Effective January 1, 1999, the Committee increased the salary
paid to Mr. Ridler, Mr. Hierro and Mr. Westerburg. The increase reflected
consideration of competitive data reported in compensation surveys and the
Committee's assessment of the performance of such executives over the
intervening year and recognition of the Corporation's performance during 1998.
In addition, the Committee approved compensation increases for all other
executive officers of the Corporation. The Mahoning National Bank Board approved
all of such increases upon recommendation of the Committee. Executive Officer
salary increase determinations are based upon written performance appraisals of
such executives which reviews, among other things, the performance of executives
against goals set in the prior year, extraordinary service and promotions within
the organization.

         EXECUTIVE DEFERRED CASH AND EXECUTIVE PHANTOM STOCK BONUS PLANS. In
1998, Mr. McHenry was not eligible to participate in the Executive Deferred Cash
Bonus Plan ("Deferred Cash Bonus Plan"). Messrs. Ridler, Hierro and Westerburg
participate in the Executive Phantom Stock Bonus Plan ("Phantom Stock Plan").
Pursuant to the terms of the Deferred Cash Bonus Plan, Mr. McHenry is eligible
for a deferred cash bonus in the years 1996 and 1997 when The Mahoning National
Bank's earnings achieved predetermined corporate levels. Under the terms of the
Phantom Stock Plan, participating executives are eligible for deferred phantom
stock bonuses, according to similar predetermined corporate earnings performance
levels. Under the terms of the plans the participating executives are eligible
to receive a deferred bonus of from 2.5 percent to 50 percent of their
compensation. In the case of the Deferred Cash Bonus Plan, the bonus is credited
to the account of the participating executive and accrues an additional 8
percent per annum in interest. Under the terms of the Phantom Stock Plan the
bonus is credited in the participant's phantom stock account in Phantom Shares,
the value of which is then determined with reference to the value of the
Corporation's common stock, plus additional credits to the account to reflect
dividends paid on the stock. In connection with both plans, the benefits are
payable upon termination of employment or retirement in a lump sum or over a
term at the election of the participant and are subject to a vesting schedule.
The Executive Committee of The Mahoning National Bank's Board of Directors has
complete discretion in the administration and interpretation of the plans.

THIS REPORT ON COMPENSATION IS SUBMITTED BY THE EXECUTIVE COMMITTEE MEMBERS:

             Warren P. Williamson, III, Chairman      Frank A. Kramer
             David A. Bitonte                         Charles J. McCrudden, Jr.
             William J. Bresnahan                     Gregory L. Ridler
             Lee Burdman                              Daniel B. Roth

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION.

         Mr. Ridler, the Corporation's Chairman of the Board, President and
Chief Executive Officer, served on the Executive Committee (the "Committee") of
The Mahoning National Bank, which is responsible for compensation matters (see
"Report of the Executive Committee of The Mahoning National Bank on
Compensation" in this Proxy Statement).

         Although Mr. Ridler served on the Committee, he did not participate in
any decisions regarding his own compensation as an Executive Officer. Each year,
the Executive Committee determines the amount of the bonus award for the
Chairman, President and Chief Executive Officer (pursuant to the Executive
Phantom Stock Bonus Plan described elsewhere in this Proxy Statement) and salary
for the ensuing year. Mr. Ridler did not participate in discussions or
decision-making relative to his compensation.

PERFORMANCE GRAPH - Five-Year Shareholder Return Comparison

         The SEC requires that the Corporation include in this Proxy Statement a

an indexed basis with a broad equity market index and either a nationally
recognized industry standard or an index of peer companies selected by the
Corporation. The Corporation has selected the Dow Jones Equity Market Index and
the Dow Jones Regional Bank Index for purposes of this performance

CHANGE OF CONTROL AGREEMENT

         The Corporation has entered into Change of Control Agreements
(the "Agreements") with Messrs. Ridler, Hierro and Westerburg. The Agreements
provide the executives are entitled to monthly periodic payments in the event of
a termination of employment (other than for cause) following a Change of
Control. A Change of Control is defined to include a merger or other acquisition
of the Corporation or the Mahoning National Bank and certain other changes in
the voting control of the Corporation. In the event of a Change of Control and
termination of the executive, the Agreements provide for the payment of monthly
cash payments equal to the highest monthly base salary of such executive prior
to the Change of Control, for 36 months in the case of Mr. Ridler and 24 months
for each of the other named executive officers. The rights of the Corporation to
choose to employ or terminate the executives prior to a Change of Control are
not affected by the Agreements. In the event a Change of Control had occurred on
January 1, 1999, and each of the executive's employment had been involuntarily
terminated on such date (other than for cause), Mr. Ridler would have been
entitled (subject to certain immaterial modifications provided for by the
Agreements which may lower the amount), to receive a monthly sum of $19,875 for
36 months; Messrs. Hierro and Westerburg would have been entitled (subject to
certain immaterial modifications provided for by the Agreements which may lower
the amount), to receive a monthly sum of $9,167, and $7,667, respectively for 24
months.

                          TRANSACTIONS WITH MANAGEMENT

         Directors of The Mahoning National Bank and the Corporation and their
associates were customers of, and have had transactions with, The Mahoning
National Bank in the ordinary course of business during 1998.

         These transactions consisted of extensions of credit by The Mahoning
National Bank in the ordinary course of business and were made on substantially
the same terms as those prevailing at the time for comparable transactions with
other persons. In the opinion of the management of The Mahoning National Bank,
those transactions do not involve more than a normal risk of being collectible
or present other unfavorable features. The Mahoning National Bank expects to
have, in the future, banking transactions in the ordinary course of its business
with directors and their associates on the same terms, including interest rates
and collateral on loans, as those prevailing at the time of comparable
transactions with others.

      COMPLIANCE WITH SECTION 16(a) OF THE SECURITIES EXCHANGE ACT OF 1934

         Section 16(a) of the Securities Exchange Act of 1934 requires the
Corporation's officers and directors, and persons who own more than 10 percent
of a registered class of the Corporation's equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Officers, directors and greater than 10 percent shareholders are required by SEC
regulation to furnish the Corporation with copies of all Section 16(a) forms
they file.

         Based solely on review of the copies of such forms furnished to the
Corporation, or written representations that no Form 5s were required, the
Corporation believes that during 1998, all Section 16(a) filing requirements
applicable to its officers, directors, and greater than 10 percent beneficial
owners were complied with.

                              SELECTION OF AUDITORS

         Crowe, Chizek and Company LLP has been appointed to serve as the
Independent Auditor for the Corporation and its subsidiary for the fiscal year
ended December 31, 1998. It is the intention of the Corporation to appoint
Crowe, Chizek and Company LLP as Independent Auditor for 1999. Representatives
of Crowe, Chizek and Company LLP are expected to be present at the Annual
Meeting to respond to appropriate questions from stockholders and to have the
opportunity to make any statements they consider appropriate.


                              SHAREHOLDER PROPOSALS

         Any proposals to be considered for inclusion in the proxy material to
be provided to shareholders of the Corporation for its next annual meeting, to
be held in 2000, must be made by a qualified shareholder and must be received by
the Corporation no later than October 8, 1999.
