our initial public offering, and no active public market currently exists for

lower than the public offering price. The minimum purchase required is 100
shares which totals $3,000 at the purchase price of $30.00 per share. For
information on how to subscribe, please see page 7 of this prospectus.

                    QUESTIONS AND ANSWERS ABOUT THE OFFERING
    
 
   
Q: Why is CNBC offering these securities and why has it chosen this time for the
   offering?
    
 
   
A: CNBC and Commerce National must comply with certain regulations regarding the
   amount of capital maintained in both organizations. It is management's desire
   to maintain its current capital classifications. As a result of rapid asset
   growth over the past two years, CNBC desires to raise new capital so that it
   may continue to grow and serve new customers.
    
 
   
Q: Once I have read the information contained in this prospectus and determined
   I would like to buy some stock, how do I subscribe?
    
 
   
A: You must complete and return both the subscription application and
   subscription agreement and enclose a check or money order payable to "CNBC
   Bancorp" for your entire subscription. The application and agreement are
   enclosed as Exhibits A and B.
    
 
Q: When will the offering close and how soon should I send in my subscription?
 
   
A: Send in your subscription as soon as possible. Management anticipates closing
   the offering as soon as possible, but no later than 90 days from the date of
   this prospectus (subject, however, to up to a 30 day extension in
   management's discretion). Management reserves the right to close the offering
   at an amount which is less than 125,000 shares.
    
 
Q: How much stock may I purchase?
 
A: The minimum purchase is 100 shares. Management has not established a maximum
   amount; however, management has the right to return part or all of your
   subscription, with interest.
 
Q: Who can I call if I have further questions?
 
A: Call John Romelfanger or Tom McAuliffe at (614) 848-8700.
 
Q: Can I purchase shares through an IRA or other qualified retirement plan?
 
A: Yes. The administrator or trustee would still need to fill out all
   appropriate forms and return them on a timely basis.
 
Q: Is this offering valid in all 50 states?
 
   
A: No. At this time we have only filed to register in the State of Ohio. If you
   are not a resident of Ohio, please call John Romelfanger or Tom McAuliffe
   before subscribing for shares.
    
 
   
Q: Why is the offering only registered in Ohio?
    
 
   
A: Each state charges fees to register the offering, which can be as much as
   $1,000 plus attorney fees. We currently do not feel the expense of
   registering in other states is cost effective.
    
 
Q: If my subscription is accepted, when will I receive my shares?
 
   
A: We will mail stock certificates to subscribers 15 days after we close the
   offering.
    
 
Q: Can I change my mind after I have mailed my subscription?
 
A: No. Once we have received and processed your subscription and payment, you
   cannot ask for a refund.
 
   
Q: What happens if you do not receive subscriptions for all 125,000 shares by
   the expiration date of the offering?
    
 
   
A: Management has the option to extend the expiration date of the offering by 30
   days, which it may do depending on the actual number of shares subscribed
   for. Management will accept subscriptions received, even if all 125,000
   shares are not subscribed for.
    
 
   
Q: What happens if we receive subscriptions for more than 125,000 shares?
    
 
   
A: Management has sole discretion regarding which subscriptions it will accept
   and which ones it will return. We will consider several factors in making
   this decision, including whether the subscriber is a current or prospective
   customer or vendor, a current shareholder or is located in our current
   geographic service area. If your subscription is returned, we will pay you
   interest from the time we receive your subscription until the date we return
   it.

                                  RISK FACTORS
 
   
     Before you invest in our common shares, you should be aware that there are
risks, including those described below. You should consider these risk factors
together with all of the other information included in this prospectus before
you decide to purchase our common shares.
    
 
   
IF AN ACTIVE TRADING MARKET DOES NOT DEVELOP, YOU MAY NOT BE ABLE TO SELL YOUR
SHARES.
    
 
   
     Prior to the offering, there has not been an active public market for
CNBC's common shares. Due to the small size of this offering, it is highly
unlikely that an active trading market will develop and be maintained. If an
active market does not develop, you may not be able to sell your common shares
as quickly as you desire, or perhaps at all, or sell your common shares at a
price equal to or above the price you paid for them. See "Market for Common
Equity and Related Stockholder Matters."
    
 
   
CHANGES IN OUR KEY PERSONNEL MAY HAVE AN ADVERSE EFFECT ON OUR SUCCESS.
    
 
   
     Our future success depends heavily on the continued involvement of Messrs.
Thomas D. McAuliffe and John A. Romelfanger. Should either of them leave the
employ of CNBC or Commerce National, our profitability, service quality and
growth may be adversely affected. Mr. McAuliffe continues to be significantly
involved in business development and client service in addition to his
administrative duties as Chairman of the Board, President and Chief Executive
Officer of both CNBC and Commerce National. Mr. Romelfanger is responsible for
many of the administrative, financial and operational aspects of both CNBC and
Commerce National and serves as Vice President, Secretary and Treasurer of CNBC
and Chief Operating Officer and Chief Financial Officer of Commerce National.
    
 
   
     We have entered into an employment contract with Mr. McAuliffe, but cannot
be assured of the continued service of either Mr. McAuliffe or Mr. Romelfanger.
We carry key person life insurance on both Mr. McAuliffe and Mr. Romelfanger, as
well as certain other senior officers. See "Executive Compensation -- Employment
Agreement."
    
 
   
SALES OF LARGE BLOCKS OF PREVIOUSLY ISSUED SHARES MAY DEPRESS THE VALUE OF YOUR
SHARES.
    
 
   
     There are currently 1,116,972 outstanding shares of CNBC common stock.
These shares were purchased at an estimated average price of $6.75. Current
shareholders may try to lock in potentially sizeable capital gains by selling
their shares after the offering. If a large number of these sales occur, or the
market perceives that such sales could occur, the value of your shares may
decline. Additionally, CNBC has 16 shareholders who own more than 10,000 shares.
If one or more of these shareholders decides to sell substantially all of their
shares, it may adversely affect the market price of the shares. See "Security
Ownership of Certain Beneficial Owners and Management" and "Shares Eligible For
Future Sale."
    
 
   
OUR WHOLESALE DEPOSITS MAY HAVE A HIGHER LIQUIDITY RISK AND HIGHER INTEREST COST
THAN OTHER TYPES OF DEPOSITS.
    
 
   
     We have a higher percentage of deposits from wholesale sources than
similarly sized banks. A wholesale deposit is typically defined as a certificate
of deposit over $100,000 and brokered deposits, which are usually issued in
increments of $99,000. While these deposits help to control operating costs by
maintaining a smaller number of accounts, obtaining these deposits is typically
a function of whether an attractive interest rate is paid which affects the
overall interest cost of deposits. If Commerce National does not pay an
attractive rate of interest, it may not be able to renew these deposits
resulting in outflows of funds. See "Management's Discussion and Analysis" and
"Supervision and Regulation."
    
 
   
THE OFFERING PRICE MAY NOT INDICATE THE MARKET PRICE OF OUR SHARES.
    
 
   
     The $30 per share offering price was determined by the CNBC Board of
Directors and is substantially higher than the current book value of the shares.
The market price of the shares after this offering could be lower than the
offering price. See "Dilution," "Market for Common Equity and Related
Stockholder Matters" and "Determination of Offering Price."

CNBC'S ALLOWANCE FOR LOAN LOSSES MAY NOT BE ADEQUATE TO ABSORB FUTURE LOAN
LOSSES.
    
 
   
     Using both objective and subjective factors, CNBC has established an
allowance for loan losses on its balance sheet that management believes is
adequate to absorb probable loan losses in its portfolio. However, the following
factors make CNBC's evaluation of its allowance more subjective than other
banks' with an established history:
    
 
   
     - Commerce National is only 7 years old, during which time the local
       economy has not experienced any significant recessionary periods.
    
 
   
     - Because of the small business focus, CNBC's average loan size is much
       larger than average loan size of many comparable banks.
    
 
   
     - Since its inception, Commerce National has grown substantially,
       especially over the last 2 years, and loan quality problems often take
       several years to materialize.
    
 
   
     - Commerce National's short history may not allow management to accurately
       predict loan losses based on historical experience.
    
 
   
     Because of these factors, CNBC may have a higher risk that its allowance
for loan losses may not be adequate to absorb future loan losses.
    
 
   
     See "Description of Business-Lending."
    
 
   
THE EXERCISE OF CNBC STOCK OPTIONS AND WARRANTS MAY DILUTE YOUR INTEREST.
    
 
   
     CNBC has 235,610 shares reserved for issuance in the event of the exercise
of existing stock options and warrants by their respective holders. These
options and warrants allow their holders to purchase specified amounts of stock
for a period of time at a fixed price. The exercise of these options and
warrants could have a dilutive effect on the earnings per share and book value
of CNBC common stock to existing shareholders. See "Dilution" and Notes 10 and
11 to the Consolidated Financial Statements.
    
 
   
POTENTIAL YEAR 2000 COMPUTER MALFUNCTIONS MAY ADVERSELY AFFECT OUR OPERATIONS.
    
 
   
     Commerce National's ability to process and record virtually all customer
transactions depends on the utilization of several different computer programs.
In addition, the business of many of Commerce National's customers is highly
dependent on computer programs. The year 2000 problem common to most
organizations involves the inability of their software and databases to
recognize year 2000-related dates. If not corrected, this problem could result
in disruptions which could prevent the borrowers from repaying their loans to
Commerce National. Moreover, the fear of such program failure may result in
unexpected withdrawals from Commerce National deposit accounts. Management has
developed and is in the process of implementing formal plans to evaluate and
minimize the risks created by these issues. Contingency plans have also been
developed to provide alternate solutions should systems used internally by
Commerce National fail to process data consistently before and after the century
date change. See "Management's Discussion and Analysis - Year 2000."
    
 
   
POTENTIALLY ADVERSE EFFECT OF GOVERNMENT REGULATION.
    
 
   
     We are subject to extensive supervision and regulation by the Federal
Reserve Board, the Federal Deposit Insurance Corporation and the Office of the
Comptroller of the Currency. Many of these laws and regulations are intended to
protect depositors, loan customers, the public and the FDIC, not the
shareholders' interests. The regulatory requirements imposed upon us may change
rapidly and unpredictably, and could adversely affect the banking industry in
general or our operations in particular. See "Supervision and Regulation." Our
Articles and Regulations contain provisions that could deter takeover attempts,
even at a price attractive for shareholders.
    
 
   
OUR ARTICLES AND REGULATIONS CONTAIN PROVISIONS THAT COULD DETER TAKEOVER
ATTEMPTS, EVEN AT A PRICE ATTRACTIVE TO SHAREHOLDERS.
    
 
   
     CNBC's Articles of Incorporation and Regulations, along with Ohio and
federal law may make it difficult to change or gain control of CNBC, even at an
attractive price to shareholders. As a result, shareholders who might
    
                                        3
<PAGE>   8
 
   
desire to participate in such a transaction may not have an opportunity to do
so. These provisions may reduce the market price of CNBC shares. Some of these
provisions may also make the removal of the current Board of Directors or
management more difficult. These provisions include:
    
 
   
     - restrictions on the acquisition of CNBC's equity securities;
    
 
   
     - the classification of the terms of the members of the Board of Directors;
    
 
   
     - shareholders meeting restrictions;
    
 
   
     - the issuance of serial preferred stock and additional      shares of
       common stock without shareholder approval; and
    
 
   
     - supermajority provisions for the approval of certain business
       combinations.

FORWARD -- LOOKING STATEMENTS.
    
 
   
     Some of the information in this prospectus may contain forward-looking
statements. Such statements can be identified by the use of forward-looking
terminology such as "may," "will," "expect," "anticipate," "estimate,"
"continue" or other similar words. These statements discuss future expectations,
contain projections of results of operations or of financial condition or state
other "forward-looking" information. When considering such forward-looking
statements, you should keep in mind the risk factors and other cautionary
statements in this prospectus. The risk factors noted in this section and other
factors noted throughout this prospectus, including certain risks and
uncertainties, could cause our actual results to differ materially from those
contained in any forward-looking statement.
    
 
                                USE OF PROCEEDS
 
   
     The net proceeds to CNBC from the sale of the 125,000 common shares offered
hereby, assuming a public offering price of $30.00 per share, and after
deducting sales commissions and the estimated offering expenses, are estimated
to be approximately $3.71 million. CNBC currently intends to utilize all of the
net proceeds it receives to purchase subordinated debentures and common stock of
Commerce National to increase Commerce National's capital ratios.
    
 
   
     CNBC currently anticipates investing 50% of the proceeds in Commerce
National common stock and 50% in subordinated debentures issued by Commerce
National. The final determination on the use of proceeds will be based on the
impact of each on the regulatory capital ratios required to be maintained by
Commerce National and the impact of state franchise taxes on each.
    
 
   
     The allocation of the use of net proceeds represents management's estimates
based upon current business and economic conditions. Although CNBC does not
contemplate material changes in the proposed allocation of the use of proceeds,
to the extent CNBC finds that adjustment is required by reason of existing
business conditions the amounts shown may be reallocated or put to different
uses.
    
 
                        DETERMINATION OF OFFERING PRICE
 
   
     The offering price of the shares was set by the Board of Directors of CNBC
based on several factors. The factors given the most weight by the Board were
price to earnings ratios ("PE ratio") and book value to market value multiples
("BV multiple") of other publicly traded bank holding company stocks. The main
group utilized

Listed below are price indicators and performance measures for the group
compared to CNBC:

     The Board also reviewed price indicators for bank holding companies of
similar size located in other midwestern states and much larger, publicly traded
Ohio bank holding companies. Other factors considered in the determination of
the offering price included recent trades of CNBC's stock, which are limited,
CNBC's geographic location and the stability of its management. Based on this
information, the Board established what it felt was a fair PE ratio and BV
multiple for CNBC's common shares to be sold in this offering.
    
 
                                    DILUTION
 
   
     At December 31, 1998, the book value of CNBC was $12.0 million, or $10.72
per share. After taking into consideration the changes in book value resulting
from the sale by CNBC of the common shares offered hereby at an assumed public
offering price of $30.00 per share, and after taking into consideration
application of the net proceeds from this offering as well, the pro forma book
value of CNBC at December 31, 1998 would have been $15.7 million, or $12.62 per
share. This represents an immediate increase in net book value of $1.90 per
share to existing shareholders and dilution in net book value of $17.38 per
share to purchasers of common shares in this offering. Book value is determined
by dividing shareholders' equity by the number of shares outstanding. Book value
is not necessarily indicative of the fair market value of shares outstanding.
The following table illustrates the book value dilution to purchasers of common
shares in this offering:

(1) Pro forma book value equals the $12.0 million of adjusted shareholders'
    equity, plus net proceeds of $3.71 million from this offering, divided by
    1,241,972 pro forma shares outstanding.
    
 
   
(2) Dilution is determined by subtracting the pro forma book value after this
    offering from the public offering price paid by investors in this offering.
    The pro forma book value per share would be $12.62 and the dilution to
    investors would be $17.38.
    
 
   
     The directors and executive officers have purchased their shares at various
times throughout Commerce National's history and at prices significantly lower
that the current offering price. Of the total shares currently owned by
directors and executive officers, which are detailed under "Security Ownership
of Certain Beneficial Owners and Management", approximately 73% were purchased
in Commerce National's initial offering in 1991 at an adjusted price of $5.68.
In the next two offerings, closed in 1992 and 1994, directors' purchases of
common

stock comprised 8% and 6% of shares currently held at prices equal to $6.82 and
$8.18, respectively. Directors and officers have acquired additional shares
through the exercise of warrants and stock options, purchases of common stock in
the secondary market and in CNBC's privately placed stock offering closed in
1997. Additionally, directors and officers currently own approximately 70% of
CNBC's outstanding warrants, which entitle the holder to purchase a share of
common stock for $5.68 per share and expire on October 11, 2000.
    
 
   
     The following table sets forth, as of December 31, 1998, the number of
common shares purchased from CNBC and the total consideration paid to CNBC by
existing shareholders and the new investors purchasing common shares in the
offering at the public offering price of $30.00 per share (before deducting
estimated offering expenses):

</TABLE>
    
 
   
     As part of its initial stock offering in 1991, Commerce National issued
warrants to all purchasers of common stock. A warrant is a freely transferable
certificate which entitles the holder to purchase a share of common stock at the
initial stock offering price of $5.68. These warrants expire on October 11,
2000. As consideration for funding the initial start-up costs for Commerce
National, the founding organizers received one warrant for every five shares of
common stock which they purchased. All other initial shareholders received one
warrant for every twenty shares purchased in the offering.
    
 
   
     If all existing warrants were exercised, CNBC would receive $338,000 in new
capital and would issue 59,520 shares. This would reduce the pro forma book
value after this offering from $12.62 per share to $12.31 per share.
Additionally, diluted earnings per share, on a pro forma basis, would be reduced
by approximately $.01 per share.
    
 
   
     Stock options differ from warrants in several ways, which we have listed
below.
    
 
   
     - Options are not transferable, they are exercisable only by the employee
       or director originally granted the option.
    
 
   
     - A gain is measured on the exercise date between the market value and
       exercise price of the stock which is recognized by the individual as
       compensation. Additionally, CNBC receives a tax deduction for the amount
       of gain recognized by the individual. This tax savings is treated as
       additional payment for the stock and is directly credited to the capital
       accounts of CNBC.
    
 
   
     - Currently, options granted have a three or five year vesting schedule
until they can be exercised.
    
 
   
     See Note 11 to the consolidated financial statements for additional
disclosures regarding stock options.
    
 
   
     If all existing dilutive options were exercised, CNBC would receive a total
of approximately $2,668,000 in new capital and would issue 162,830 shares.
Because the average price per share is $16.39, CNBC's pro forma book value would
actually increase. The maximum amount diluted earnings per share would be
reduced if all options were immediately exercised would be $.10 per share,
assuming CNBC did not repurchase any of these shares and hold them as treasury
stock.
    
 
                              PLAN OF DISTRIBUTION
 
GENERAL
 
   
     The prospectus is dated February   , 1999. The offering commences this date
and shall remain open for up to 90 days thereafter, except as follows: this

shares, or to reject or cancel any subscription, in whole or in part, for any
reason whatsoever. Management will consider the following factors in determining
which subscriptions it will accept and which ones it may reject:
    
 
   
     - whether the subscriber is a current or prospective customer or vendor
    
 
   
     - whether the subscriber is a current shareholder
    
 
   
     - the size of the subscription
    
 
   
     - whether the subscriber is located in Commerce National's current
       geographic service area
    
 
   
No investor may own, directly or indirectly, an amount of shares equal to or
greater than 10% of CNBC's outstanding shares without the consent of CNBC and
the Federal Reserve Board.
    
 
   
     This offering is not underwritten and is not conditioned on the sale of any
minimum number of shares. Only the directors and officers of CNBC and authorized
selling agents are authorized to solicit subscriptions for shares. The directors
and officers of CNBC intend to solicit by means of personal and telephone
contact with prospective subscribers, and by direct mailing of the prospectus.

     The prospectus includes two appendices: Appendix A, the subscription
application and Appendix B, the subscription agreement. Executable copies of the
application, together with IRS Form W-9 accompany the prospectus. The prospectus
and subscription agreement are incorporated by reference in the application. By

     On the last day of the offering, CNBC will conduct a closing at its
offices. If the offering is extended by 30 days, CNBC will provide written
notice of such extension to all investors. The last possible date on which this
offering may close is June   , 1999. Upon the closing, subscription funds in the
Escrow Account relating to applications accepted by CNBC, shall be released to
CNBC in the amount corresponding to the shares purchased by investors.
Applications shall be closed at the earliest date after CNBC, in its discretion,
has determined that all of the requirements of the related application and
agreement have been met, the subscription has been accepted and the requisite
good funds deposited in the Escrow Account.

                                DIVIDEND POLICY
 
   
     As a one bank holding company, the ability of CNBC to pay dividends to its
shareholders is primarily dependent upon the receipt of dividends and interest
payments from Commerce National. Without the approval of the Comptroller of the
Currency, Commerce National may not pay a dividend to CNBC if the total of all
dividends declared by Commerce National in any calendar year exceeds the total
of net profits for that year combined with its retained net profits for the
preceding two calendar years, less any required transfers to surplus or fund for
the retirement of any preferred stock. Commerce National's ability to pay
dividends is also dependent upon its ability to continue to meet regulatory
capital requirements. See "Supervision and Regulation" and Note 14 to the
Consolidated Financial Statements.
    
 
   
     In December 1995, Commerce National declared its first annual cash dividend
to shareholders. CNBC's current policy is to declare dividends semi-annually in
June and December. Noted below are dividends declared for the years ended 1998
and 1997.

     Although CNBC intends to continue to pay cash dividends on its common
shares in the future based upon its net income and available cash flow, there
can be no assurance that CNBC will have earnings sufficient to pay a dividend on
its common shares or that, even if there are sufficient earnings, dividends will
be permitted under applicable laws or regulatory requirements. Declaration of
dividends will be considered by the Board of Directors semi-annually and will be
determined, at the discretion of the Board of Directors, in light of CNBC's
results of operation, financial condition, capital requirements, contractual
restrictions and other factors deemed relevant by the Board of Directors. The
Board of Directors will also periodically consider stock dividends as a means of
enhancing the liquidity and marketability of CNBC's stock.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
 
   
     The following discussion presents an analysis of CNBC's financial condition
and results of operations as of and for the year ended December 31, 1998
compared to December 31, 1997, and with respect to the year ended December 31,
1997 compared to the year ended December 31, 1996. This discussion is designed
to provide the reader with a more comprehensive review of the operating results
and financial position than could be obtained from reading the financial
statements alone. Forward-looking statements contained in this discussion
involve risks and uncertainties and are subject to change based on various
important factors. Actual results could differ from those expressed or implied.
This analysis should be read in conjunction with the financial statements and
related footnotes and the selected financial data included elsewhere in this
prospectus.
    
 
   
COMPARISON OF FINANCIAL CONDITION AT DECEMBER 31, 1998 AND DECEMBER 31, 1997
    
 
   
     Total assets increased $36 million, or 26%, to $175 million at December 31,
1998. The two largest components of this increase are an increase of $32 million
in loans outstanding and an increase in cash and cash equivalents of $2.4
million.
    
 
   
     The increase in loans is comprised primarily of a $17 million increase in
real estate investment loans and a $12 million increase in business loans. These
increases are in line with Commerce National's budgeted growth for the year and
are comparable to the growth experienced by Commerce National during the last
several years. In 1998, the sale of a locally owned savings bank to a regional
bank holding company resulted in Commerce National receiving more opportunities
for new customers, especially those with investment real estate loans.
    
 
   
     Over the past three years, Commerce National has experienced loan growth of
$82 million. Of this total, 53% has been in business real estate loans and 35%
in business lines of credit and term loans. Management anticipates opportunities
are good for continued growth in these lending areas due to Commerce National's
small business focus, a strong, local economy, and continuing consolidation of
its competitors.
    
 
   
     The primary increase in liabilities was a $32 million increase in deposit
accounts. Of this increase, $5 million was in interest bearing demand accounts
and a result of increased business with title companies. Savings balances grew
$19 million and are a result of Commerce National's small business focus and
available cash management products for its customers. Certificates of deposit
grew $4 million, with $2.5 million of this growth achieved through solicitation
of deposits on the national rate-listing network to which Commerce National
subscribes.
    
 
COMPARISON OF FINANCIAL CONDITION AT DECEMBER 31, 1997 AND DECEMBER 31, 1996
 
   
     Commerce National experienced its highest percentage growth in its history
during 1997. Total assets grew $35 million, an increase of 34% over year end
1996.
    
 
   
     Loans increased substantially in 1997, increasing $32 million for the year.
Real estate investment loans grew $16 million and business loans grew $12
million, both reflecting the focus of Commerce National on small business and
entrepreneurs.
    
 
     Premises and equipment increased $1.6 million, reflecting management's
decision to purchase its existing main office building.
 
   
     The primary increase in liabilities was a $29 million increase in deposits.
Of this amount $15 million was in savings and $12 million was in certificates of
deposit. As previously stated, Commerce National's focus on small business and
innovative cash management products have resulted in increases in savings
balances of corporate customers. A total of $10 million of the $12 million
increase in certificates of deposit was due to deposits raised through the
national rate-listing network.
    
 
   
     Additionally, borrowings increased $4 million, with $2 million of the
increase representing a long term loan payable used by CNBC to supplement the
capital of Commerce National. CNBC also issued $1 million in new common stock
pursuant to a private placement.

RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1998 COMPARED TO THE YEAR
ENDED DECEMBER 31, 1997
    
 
   
     Net income for the year ended December 31, 1998 was $1,824,000, a 30.8%
increase over the $1,395,000 reported for 1997. The increase in net income was
primarily driven by a $1,400,000 increase in net interest income, offset by a
$712,000 increase in operating expenses, a $94,000 increase in the provision for
loan losses and a $224,000 increase in federal income tax expense.
    
 
   
     The 27.4% increase in net interest income was primarily the result of an
increase in average loans outstanding of 31% for 1998 compared with 1997.
Similar to 1997, loan growth was most significant in the business and real
estate investment loan categories, which reflects Commerce National's business
focus and an expanding local economy. At December 31, 1998, approximately 18% of
business real estate loans were for the purpose of financing business customers'
operating facilities. The remaining 82% of business real estate loans were for
the purpose of financing residential and commercial investment properties.
Management attributes Commerce National's loan growth to a number of factors,
including:
    
 
   
     - Referrals from existing customers who are pleased with the service
       quality they receive from Commerce National;
    
 
   
     - Primary focus of 14 of Commerce National's 37 full-time employees on
       business development and existing customer relationship satisfaction,
       which helps to insure the quality and responsiveness of service Commerce
       National's customers expect;
    
 
   
     - Continued involvement of CNBC's outside directors in business development
       efforts;
    
 
     - A vibrant, diverse, local economy; and
 
   
     - Continuing consolidation of local competitors which results in a lesser
       focus on providing quality customer service by Commerce National's
       competitors.
    
 
   
     Commerce National's net interest margin declined slightly during this
period due to a slightly lower percentage of its earning assets invested in
loans and a small decrease in the average yield on interest earning assets.
    
 
   
     Management anticipates that the local economy will continue to expand
although at a slower pace than in the last 24 months. Several large employers,
such as Wendy's International, The Limited and related companies, Nationwide
Insurance, The Ohio State University, and the State of Ohio governmental
entities, complement a large number of small and emerging businesses to create
an economy that has grown steadily and is less susceptible to significant
downtrends because of its diversity.
    
 
     The increase in the provision for loan losses is due to the growth of the
overall loan portfolio.
 
   
     The 25.7% increase in operating expenses is broken down as follows:
    
 
   
<TABLE>
<S>                                                             <C>

Customer Courier............................................      29,000
State Franchise Tax and Other Expenses......................     166,000
</TABLE>
    
 
   
     The increase in salaries and benefits is due to personnel additions to
generate and support Commerce National's growth. During 1998 and 1997, Commerce
National hired 8 and 7 full-time employees, respectively, with only one employee
termination. One of the key measures utilized by management to track personnel
efficiency is the dollar amount of revenues generated per dollar amount of
personnel expense. For the years ended December 31, 1998 and 1997, these figures
were $3.25 and $3.46, respectively. The decrease in Occupancy and Equipment
expense is due to the impact of the purchase of Commerce National's main office
in June, 1997 compared to leasing the facility. The building is fully leased
with Commerce National occupying approximately
    
 
                                       13
<PAGE>   18
 
   
40% of the building. Rental income received is offset against the operating cost
for the office. The increase in legal and professional fees are related to loan
workout situations and other corporate matters. The remaining increases in
expenses are due to Commerce National's continued growth. The increase in
federal income tax expense is the result of CNBC's increased profitability.
    
 
   
RESULTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 1997 COMPARED TO THE YEAR
ENDED DECEMBER 31, 1996
    
 
     Net income for 1997 was $1,395,000, a $332,000, or 31% increase over 1996.
This increase is the result of an increase of $1,131,000 in net interest income
and $27,000 in other income offset by increases of $131,000 in the provision for
loan losses, $523,000 in operating expenses and $172,000 in federal income tax
expense.
 
   
     The increase in net interest income of 28% was the result of a 30% increase
in average loans outstanding. CNBC's net interest margin increased slightly to
4.62% from 4.47% in 1996, primarily a result of a higher percentage of average
earning assets in loans. For the second year in a row, growth in the real estate
investment loan category was strong at $16.2 million for 1997. Loans to
businesses for operating purposes, equipment and other needs also increased
significantly, growing $12.6 million. The growth in these areas was the result
of a strong local economy, CNBC's small business focus and the addition of
several business development personnel during the past 18 months. Growth in
other income is primarily the result of increased service charge income on
deposit accounts. Deposits increased $28.7 million in 1997, the largest annual
increase CNBC has experienced. Of this amount, $15.4 million was in savings
deposits, which includes excess savings funds of business customers utilizing
Commerce National's automated funds management systems. Additionally,
certificate of deposit growth was primarily the result of an increase of $10.2
million in funds solicited through the national rate listing network to which
Commerce National subscribes.
    
 
     The increase in the provision for loan losses of $131,000 reflects amounts
determined necessary to support the growth in the loan portfolio and partially
offset loan charge-offs experienced in 1997 of $50,000.
 
     Changes in operating expenses are summarized as follows:
 
<TABLE>
<S>                                                             <C>
Salaries and benefits.......................................    $324,000
Occupancy and equipment.....................................     (14,000)
Data Processing.............................................      30,000
Other.......................................................     183,000
</TABLE>
 
   
     Most of these changes in operating expenses were a result of Commerce
National's asset and deposit growth. The personnel efficiency ratio, defined as
total net revenues divided by salaries and benefits, increased slightly to $3.46
for 1997 compared to $3.43 for 1996. The decrease in occupancy and equipment
reflects the decision by Commerce National to purchase its main office building
on June 1, 1997. The rent income received from tenants offsets the operating
costs of the building and has resulted in a net decrease in its operating costs
compared to the rent expense paid in 1996 when Commerce National was a tenant in
the building. The largest increases in other expenses are legal fees of $54,000,
courier fees of $31,000 and check fraud losses of $35,000. The legal fees
related primarily to an increase in litigation related to certain loan
customers. The increase in courier fees represents a 27% increase over the prior
year, which is in line with Commerce National's growth. The check fraud losses
were the first ever experienced by Commerce National. Management has implemented
new procedures to attempt to minimize the future risk of these types of losses.
The increase in federal income tax expense is the result of CNBC's increased
profitability.
    
 
   
LIQUIDITY
    
 
   
     CNBC's objective in managing liquidity is to maintain the ability to
continue to meet the cash flow needs of its customers, such as new loans or
deposit withdrawals, as well as its own financial commitments. The principal
sources of liquidity are new deposit accounts, loan principal payments, money
market mutual funds, securities available for sale, federal funds sold and cash
and deposits with banks. Along with its liquid assets, CNBC has additional
sources of liquidity available to ensure that adequate funds are available as
needed which include, but
    
 
                                       14
<PAGE>   19
 
are not limited to, the sale of loan participations to other financial
institutions, the purchase of federal funds and borrowing from the Federal Home
Loan Bank. Management believes that it has the capital adequacy, profitability
and reputation to meet its current and foreseeable liquidity needs.
 
   
     The two primary liquidity needs of Commerce National are funding loans and
net withdrawals from deposit accounts.
    
 
   
     Net increases in loans totaled $32.3 million and $32.4 million in 1998 and
1997, respectively. These loan growth totals represent 96% and 93% of cash flows
used for investing activities. Loans are primarily funded through deposit
growth, supplemented by long-term borrowings. Commerce National's commitments,
as further detailed in Note 12 to the financial statements, are primarily
commitments to fund loans. New loan commitments have typically averaged between
$8 million and $16 million and result in approximately $4 million in new loans
booked per month. Net loans grow by a smaller amount due to loan payoffs.
Although Commerce National has a large amount of approved, unadvanced lines of
credit, this is not a significant liquidity risk. Management has tracked the
utilization percentage on its lines of credit which have ranged between 35% and
50%. At December 31, 1998, utilization was 42%.
    
 
   
     Listed below is a summary of the primary cash flows from financing
activities which have funded loan growth. Deposits are broken down between those
generated from Commerce National's customers located in its primary market area
("Primary") and those generated through the national rate listing network
("Brokered").

     Although Commerce National has experienced net deposit growth since its
inception, deposit balances fluctuate during the month and seasonally, in the
first quarter of the year. At December 31, 1998, Commerce National had $36
million in available short-term funding sources to mitigate any risks from
changes in deposit account balances, which represents 36% of checking and
savings deposits which can be immediately withdrawn. These sources are detailed
as follows:

CAPITAL RESOURCES
 
   
     CNBC and Commerce National are both subject to regulatory capital
requirements. These requirements measure capital levels utilizing three
different calculations. Based on these calculations, CNBC and Commerce National
are assigned to a capital category which, among other things, dictates certain
business practices of the organization, the level of Commerce National's FDIC
insurance premium and which process is followed in obtaining regulatory
approvals necessary for branch applications, mergers and similar transactions.
CNBC's capital requirements are measured on a combined basis with Commerce
National, using consolidated totals. Commerce National is measured
independently. As of December 31, 1998, CNBC was considered in the "adequately
capitalized" category and Commerce National was classified in the "well
capitalized" category. It is management's policy to manage the growth of
Commerce National and provide for the appropriate capital
    
 
                                       15

resources that will result in Commerce National maintaining its classification
as a "well capitalized" institution. Similarly, it is management's policy to
maintain the classification of CNBC as either "adequately capitalized" or "well
capitalized." For further information on capital requirements, see Note 14 to
the Consolidated Financial Statements.
    
 
   
YEAR 2000 ISSUES
    
 
   
     Management began its commitment for evaluating the impact of Year 2000
("Y2K") issues during 1997. Management's initial procedures included a thorough
inventory of all information technology ("IT") systems and all other significant
operating systems within Commerce National. All IT systems were then assigned a
rating from 100 to 0, with 100 representing the most significant systems which
required the highest level priority for testing and evaluation and 0 the least
significant. The following were the major factors considered in assigning this
rating:
    
 
   
     1. How critical is the system to customer service?
    
 
   
     2. How quickly and effectively can a contingency plan be implemented if the
        system fails due to Y2K issues?
    
 
   
     3. How many transactions are processed by the system?
    
 
   
     4. What is the potential impact to the Bank's liquidity if the system
fails?
    
 
   
Management identified three IT systems that it rated highly and classified these
systems as "mission critical." These systems are as follows and are more fully
described below, including our current status in testing and evaluating these
systems.
    
 
   
     1. Kirchman Dimension 3000
    
 
   
     2. Fedline
    
 
   
     3. Proof and Item Capture
    
 
   
Kirchman Dimension 3000 ("D3000")
    
 
   
     D3000 is the software which Commerce National utilizes for processing and
recording all customer deposit and loan transactions and accounts. D3000
prepares a daily balance sheet and income statement which are critical to the
proper operation of the Bank and serve as the base for virtually all financial
and regulatory reporting. D3000 is leased from and supported by Kirchman
Corporation and is utilized by over 500 banks across the United States ranging
in size from de novo banks to bank holding companies exceeding $15 billion in
consolidated assets. Critical to the evaluation of the software is the fact that
Kirchman Corporation does not release the source code of its computer program,
therefore all banks utilizing the software operate on the same software. No
customization or editing of the programs is permitted.
    
 
   
     Testing of D3000 has been completed by Kirchman Corporation and by Commerce
National. Kirchman Corporation completed its testing in mid-1998 and released
the testing results, including copies of documentation supporting the test
results on CD ROM disks. After reviewing the testing results, Commerce National
organized a joint, independent testing program of the software with 33 other
banks which operate D3000 on the same hardware, an IBM AS/400. A thorough review
of D3000 was made to identify all date-related fields used. Test scripts were
then developed by members of the testing group. One of the banks permitted the
use of its database of customers to complete the testing. The testing group
rented a computer hot site for a period of four weeks to operate the system
utilizing 13 differing test dates spanning December, 1999, through January,
2002. The results of this testing and the results of Kirchman Corporation's
testing revealed no significant deficiencies in D3000's ability to properly
process and record transactions and reports beyond the year 2000. Data tapes
were saved to further test the system in the fall of 1999 to confirm that any
updates completed on D3000 remain Y2K compliant.
    
 
                                       16
<PAGE>   21
 
   
Fedline
    
 
   
     Fedline is the operating software utilized to process transactions and
communicate with the Federal Reserve. The most significant transactions
processed with the Federal Reserve include wire transfers, ACH and tax payments.
The Federal Reserve has developed a comprehensive testing schedule which allows
banks to operate in a "test mode" during certain times. Commerce has completed
its testing of these three areas successfully, with no significant deficiencies
noted. Other minor areas are currently in the testing stage and will be
completed by March 31, 1999.
    
 
   
Proof and Item Capture
    
 
   
     Commerce National's proof and item capture system ("items system")
encompasses the equipment and software which is needed to magnetically encode
individual checks deposited by its customers so that they can be properly
processed by the Federal Reserve. Additionally, the items system processes loan
payments and other internal transactions as well as the checks which its
customers have written.
    
 
   
     Commerce National currently pays another area financial institution to
process its checks and other transactions. This bank's items system is currently
being tested for Y2K compliance. Testing is expected to be completed by April
30, 1999. However, Commerce National is currently in the process of purchasing
the equipment and software which will enable it to process its own items. This
new system has been certified by the vendors as Y2K compliant and will be
thoroughly tested prior to implementation by Commerce National. It is
anticipated that the new system will be tested and operational by April 30,
1999. The new system is being purchased to enhance customer service and gain
certain operational efficiencies.
    
 
   
Other IT Systems
    
 
   
     The following software systems were identified by management as requiring
some level of Y2K testing or verification. Management procedures included
confirmation with the vendors regarding Y2K compliance, review of vendor testing
plans, methodology and results and, in certain cases, actually operating the
software in a Year 2000 test mode. Results of these procedures were positive,
with no significant Y2K failures noted.
    
 
   
     1. Magicwriter ACH - Utilized by customers to initiate electronic tax
        payments, direct deposit payroll, and cash management transfers via the
        automated clearinghouse.
    
 
   
     2. Laserpro - Utilized for preparation of loan documents.
    
 
   
     3. Word and Wordperfect - Utilized for word processing.
    
 
   
     4. IPS shareholder - Utilized for maintaining shareholder records.
    
 
   
     5. FTI - Utilized for preparation of deposit account legal documents.
    
 
   
     6. Excel/Lotus - Utilized for spreadsheet applications.
    
 
   
     7. Access - Utilized for database applications.
    
 
   
     8. Equifax - Utilized for credit card and merchant processing.
    
 
   
     9. ADP - Payroll processing.
    
 
   
Other Operating Systems
    
 
   
     Management has evaluated other operating systems, including HVAC and
security. Commerce National recently updated its building security system to
achieve Y2K compliance. In January, 1999, Commerce National also implemented a
new telephone and voicemail system which is Y2K compliant. The building has all
electric utilities and is served by American Electric Power.
    
 
   
Customer Y2K Evaluation
    
 
   
     In the fourth quarter of 1998, management completed a review of all
customers with aggregate loans of $250,000 or more to assess whether any
customer had a significant risk to a Y2K related failure which would
significantly impact their business, and hence their ability to repay their
loans to Commerce National.
    
 
                                       17
<PAGE>   22
 
   
Management's procedures included a review of the customers' most recent loan
grading, review of collateral and, in some cases, completion of a detailed Y2K
questionnaire which was reviewed directly with the borrower. Based on this
information, management assigned an overall Y2K risk grade of low, medium or
high. In the aggregate, Commerce National rated its overall risk due to
potential customer Y2K issues as low. Individual borrowers rated medium or high
will continue to be monitored as new loan requests or line of credit renewals
are considered for approval by loan committee.
    
 
   
Management's Current Forecast of a "Worst Case" Scenario
    
 
   
     Commerce National is confident that its internal systems will not be
significantly affected by Y2K. However, management does anticipate that some
problems will occur with customers' systems and with their suppliers and
customers. Commerce National anticipates some potential for slower collection of
receivables by some of its customers, which would result in increased usage of
existing lines of credit and/or a decrease in savings balances. Commerce
National will maintain higher levels of liquidity in the second half of 1999
through 2000 to offset this risk. Commerce National also will enhance controls
over line of credit advances to monitor the line usage by its customers.
Commerce National's customers are minimally impacted by issues related to Y2K
issues of foreign nations or companies.
    
 
   
Y2K Costs
    
 
   
     Many of Commerce National's initiatives to update and improve IT and other
systems relates to improved operating processes and customer service. We
consider these expenditures as being "indirectly" impacted by Y2K. Therefore, we
have listed those costs we consider a "direct" result of Y2K and those that we
consider "indirect." All personnel costs are estimates of time expended by
existing Commerce National employees. No outside consultants or contractors have
been utilized.

</TABLE>
    
 
   
All of the direct costs have been incurred as of December 31, 1998. Management
anticipates all indirect costs will be incurred during the first quarter of
1999. All indirect costs will be capitalized equipment costs and depreciated
over their appropriate useful lives. Estimated direct costs to be incurred in
1999 are expected to be less than $15,000.

RATE/VOLUME ANALYSIS
 
   
     The following table represents the extent to which changes in interest
rates and changes in the volume of interest-earning assets and interest-bearing
liabilities have affected CNBC's interest income and interest expense during the
periods indicated. Information is provided in each category with respect to (i)
changes attributable to changes in volume (change in volume multiplied by prior
rate), (ii) changes attributable to changes in rate (changes in rate multiplied
by prior volume) and (iii) the net change. Changes attributable to the combined
impact

of volume and rate have been allocated proportionately to separately reflect the
changes due to the volume and the changes due to rate.

MANAGEMENT OF INTEREST RATE RISK
    
 
   
     The principal objective of Commerce National's asset/liability management
("A/L mgt") is to provide for a stable net interest margin which is the primary
component of Commerce National's revenues. The objective of A/L mgt is to
monitor the amount of assets with variable and fixed rates and fund them with
similar liabilities. This process affects loan pricing and prepayment decisions
as well as deposit and borrowing interest rates. Guidelines for A/L mgt have
been established by the Funds Management Committee of the Board of Directors and
a review is completed on a monthly basis.
    
 
   
     The following GAAP table summarizes Commerce National's dollar amount of
assets and liabilities, in thousands which either mature or have an interest
rate which will adjust within the timeframes noted. At December 31, 1998, total
interest-earning assets exceed interest-bearing liabilities by $25,347,000.
These assets are funded by non-interest bearing checking account balances and
Commerce National's capital.

At December 31, 1998, 80% of Commerce National's loans had interest rates which
adjust at least once every five years. Approximately 50% of these variable rate
loans will re-price in one year or less. Variable rate loans use either prime
rate or U.S. Treasury rates as the index which dictates changes in the loan
interest rate. Deposits and borrowings interest rates are primarily influenced
by changes in U.S. Treasury rates.
    
 
   
     Commerce National uses an interest rate risk projection model which
calculates the potential change in its net interest income over the succeeding
one-year period which would result from an instantaneous and sustained interest
rate change of plus or minus 1.00% and 2.00%. Different assumptions are made
regarding anticipated loan prepayments depending on the direction and magnitude
of the interest rate change. At December 31, 1998, management's projection model
estimates that Commerce National's net interest income over the succeeding
one-year period would be affected as follows:

                            DESCRIPTION OF BUSINESS
 
HISTORY
 
   
     CNBC was incorporated in Ohio on August 23, 1996 for the purpose of
effecting a reorganization whereby Commerce National Bank, a national bank
established in 1991 and more fully described below, would become a wholly-owned
subsidiary of CNBC and CNBC would become a bank holding company as defined in
The Bank Holding Company Act of 1956, as amended. This reorganization was
completed effective November 30, 1996.
    
 
   
     The bank holding company structure enables CNBC, in addition to owning and
operating Commerce National, to engage in business opportunities that are
determined by the Federal Reserve Board in its regulatory and supervisory
capacity to be so closely related to banking or managing a bank to be
permissible activities for a bank holding company. See "Supervision and
Regulation." As a result, CNBC will be able to offer a broader range of services
to its customers and to more effectively compete with the commercial banks in
its market area that have also reorganized into bank holding companies.
    
 
   
     The concept for the formation of Commerce National arose from the
experience of Thomas D. McAuliffe, Chairman of the Board, President and Chief
Executive Officer, as a banker servicing the needs of small and medium-sized
business owners and the experience of the initial organizers and directors, who
were founders or top level executives in such businesses. Together, Commerce
National's organizers concluded that a community business bank would fill a need
in the market in that it would better serve such businesses and their owners,
along with self-employed professionals. The concept was developed into an
operating plan emphasizing a low overhead and expense structure, a staff of
experienced bankers, and the efforts of the officers and directors in the
community.
    
 
   
     On March 30, 1990, the organizers filed with the Office of the Comptroller
of the Currency an application to charter Commerce National. The Comptroller
granted preliminary approval of the application on August 22, 1990. On October
11, 1990, the Comptroller approved the offering circular for Commerce National's
initial stock offering. Commerce National closed the initial offering on April
12, 1991 after receiving and accepting subscriptions for 777,040 shares of
common stock at an adjusted per share price of $5.68, totalling $4,415,000.
Commerce National received its charter and commenced operations on June 7, 1991.
    
 
   
     Commerce National offers customary commercial banking services to its
customers, including checking and savings accounts, electronic banking,
    
   
certificates of deposit, NOW accounts, and money market savings accounts.
    
 
                                       21
<PAGE>   26
 
   
Commerce National also offers business lines of credit and term loans, primarily
on a secured basis, and real estate loans. For consumers, many of whom are the
owners of the businesses serviced by Commerce National, Commerce National offers
residential real estate loans, home equity loans and personal loans. The
deposits of Commerce National are insured by the FDIC up to applicable limits.
Commerce National is a member of the Federal Reserve System.
    
 
MARKET AREA
 
   
     Commerce National's only office is located in a general purpose office
building at 100 East Wilson Bridge Road, Worthington, Ohio 43085, which was
purchased by Commerce National on June 1, 1997. Commerce National serves
customers primarily within and up to ten miles outside the Columbus outerbelt
(I-270). For purposes of The Community Reinvestment Act, Commerce National's
market area is defined as Franklin and southern Delaware counties. In excess of
90% of Commerce National's loan business and in excess of 75% of Commerce
National's deposits have been generated from customers in this market area. For
a further discussion on the Community Reinvestment Act see "Supervision and
Regulation."
    
 
COMPETITION
 
   
     All phases of Commerce National's business are highly competitive. Commerce
National competes with local commercial banks, many of which have assets,
capital and lending limits substantially larger than Commerce National. Commerce
National also competes with savings banks, savings and loan associations, money
market funds, insurance companies, stock brokerage firms, regulated small loan
companies, credit unions and issuers of commercial paper and other securities.
Recent Ohio and other legislation has had the effect of facilitating the ability
of financial institutions located outside Ohio to enter Ohio markets, thereby
increasing competition.
    
 
   
     As of June 30, 1998, there were 26 FDIC-insured financial institutions with
operations in the Franklin County market, ranging in asset size from $6.5
billion to less than $1 million. The four largest financial institutions control
approximately 79% of the deposits in Franklin County. As of June 30, 1998, the
most recent date for which figures are available, total deposits in Franklin
County were approximately $17.4 billion. Listed below is information on all
FDIC-insured financial institutions with deposits in Franklin County exceeding
$50 million. Total deposits and number of offices are for Franklin County only.

     Total banking deposits in Delaware County were $583 million at June 30,
1998. The dominant banks in Delaware County are The Delaware County Bank and
Trust, which controls 53% of deposits, and National City Bank, which controls
17% of deposits.
    
 
   
     In competing for money market and time deposits, Commerce National
generally offers interest rates comparable to its competitors. Borrowers are
actively encouraged to use Commerce National as their primary depository
institution.
    
 
   
     The primary means of introducing and promoting Commerce National's loan
products is through the business and personal contacts of the directors and
officers in Commerce National's market area and referrals from existing
customers.
    
 
   
     Following are several of CNBC's and Commerce National's organizational
philosophies that management believes have made Commerce National effective in
competing for and obtaining new business:
    
 
   
     - Serving the small business owner with an experienced banker. The eight
       individual account officers at Commerce National average 20 years of
       banking experience. Typical problems that small business owners encounter
       with larger banks include inexperienced account officers and turnover in
       the account officer relationship. Commerce National offers the small
       business owner an opportunity to work with an experienced professional on
       a long term basis.
    
 
   
     - Responsiveness to customer needs. The lending approval "hierarchy" in a
       large bank often dictates a time frame that is too long before a decision
       can be made on a borrowing request. Commerce National has developed
       lending authorities and committee schedules to permit prompt decisions on
       borrowing requests. All lending decisions are made by Commerce National
       at a local level.
    
 
   
     - Cost control. Commerce National has adopted a philosophy of only
       providing the banking services which are needed by small businesses and
       their owners. Commerce National currently has only one office, without a
       drive-through facility. A third party courier service is utilized to pick
       up customer deposits in lieu of an extensive branch network. This
       strategy allows Commerce National to allocate much of its resources to
       quality people and offer very competitive rates for both loans and
       deposits. Commerce National is also a member of the MAC and Money Station
       ATM networks. This membership provides Commerce National's customers with
       the ability to withdraw or deposit funds at over 150 ATM machines in the
       Columbus, Ohio metropolitan area.
    
 
CURRENT SERVICES
 
   
     Commerce National is a full service bank serving primarily the financing
and cash management needs of small to medium-sized business customers in the
central Ohio region. Commerce National does not currently offer trust services.
Banking deposit products include checking and savings accounts, certificates of
deposit, money market savings accounts, and NOW accounts. The certificates of
deposit offered have various maturities ranging from seven days to five years.
    
 
   
     Commerce National offers business lines of credit and term loans, primarily
on a secured basis, and real estate loans. For consumers, many of whom are the
owners of the businesses serviced by Commerce National, Commerce National offers
residential real estate loans, home equity loans and personal loans.
    
 
   
     Commerce National also offers credit cards to businesses and consumers,
merchant processing services to businesses and international wire and check
clearing services.
    
 
   
     Commerce National endeavors to build relationships with select small and
medium-sized businesses in its market area. Loan customers are encouraged to
bring their deposit business to Commerce National. This focus has further
increased the deposit base for Commerce National and assists in controlling
overall marketing costs related to deposit acquisition.
    
 
   
     Under the National Bank Act, Commerce National is generally prohibited from

the needs of a loan customer exceed Commerce National's lending limit, Commerce
National may sell loan participations to other banks. In all cases where
participation of a loan is required by Commerce National's underwriting policies
or applicable law, participation commitments are obtained before a loan
commitment is made to a borrower. The participation of loans serves to limit
concentrations in the loan portfolio while enabling Commerce National to meet
customer needs.
    
 
LENDING
 
   
     Commerce National has experienced high loan demand since its inception.
This demand has primarily been the result of the contacts of the officers and
directors in the community and an expanding local economy.
    
 
   
     Commerce National classifies its loans according to the following
categories:
    
 
   
     Residential Real Estate Loans. This category includes loans secured by a
first mortgage on an individual's principal residence. Loans are typically
underwritten with a loan-to-appraised value of 85% or less and compliance with
certain income-to-debt ratios. The vast majority of these loans are to the
owners of the businesses for which Commerce National provides services.
Management considers the overall loan loss risk of these types of loans to be
minimal.
    
 
   
     Real Estate Construction Loans. This category includes construction loans
for owner-occupied commercial real estate, an individual's principal residence
or real estate investment property. Construction loans for an individual's
principal residence are underwritten similarly to a residential real estate
loan. Construction loans for commercial purposes are typically written with a
loan-to-appraised value of 80% or less and compliance with cash flow and
underwriting guidelines based on the income generated by the business that will
occupy the building. Construction loans for real estate investment purposes are
typically written with a loan-to-appraised value of 75% or less and compliance
with cash flow and underwriting guidelines based on the projected income
generated by the rental of the property. Depending on the financial strength of
the borrower, a certain amount of committed leases may also be required to
approve the loan. Management considers the overall loan loss risk of these types
of loans as moderate to high.
    
 
   
     Real Estate Investment Loans. This category includes loans secured by
commercial real estate that is occupied by a Commerce National business
customer, residential investment property such as condominiums and apartments,
and commercial investment real estate that is leased to businesses which are not
Commerce National customers. At December 31, 1998, total real estate investment
loans were distributed as follows:

Loans for commercial real estate are typically written with a loan to appraised
value of 75% or less and compliance with cash flow and underwriting guidelines
based on the income generated by the business or businesses that will occupy the
building. Loans for residential investment property are typically written with a
loan-to-appraised value of 80% or less and compliance with cash flow and
underwriting guidelines based on the projected income generated by the rental of
the property. Maturities generally range from 10 to 25 years. Management
considers the overall loan loss risk of residential investment property as low
and owner-occupied and commercial investment property as low to moderate.
    
 
   
     Business Loans. This category includes lines of credit and term loans
primarily secured by accounts receivable, inventory, equipment and other
business assets. Maturities on term notes generally do not exceed five years.
Management reviews the cash flow and financial condition of the business
compared to established guidelines in determining whether to approve business
loans. Management considers the overall loan loss risk of business loans as
moderate.
    
 
   
     Personal Loans. These loans are made to individuals and include home equity
loans, stock secured loans, loans to purchase vacation homes and other loans.
Underwriting approval procedures depend on the type of loan and include criteria
for loan to collateral value guidelines and income-to-debt ratios. Management
considers the overall loan loss risk of personal loans as low.

     Management performs an analysis of Commerce National's loan portfolio on a
quarterly basis to assess the adequacy of the allowance for loan losses. The
allowance for loan losses represents that amount which management estimates is
adequate to provide for inherent losses in its loan portfolio. The allowance
balance and the provision charged to expense are determined by management based
upon past loan loss experience, economic conditions and various other
circumstances that are subject to change over time. The collectibility of
certain specific loans is evaluated based upon factors including the financial
position of the borrower, the estimated market value of the collateral at the
current time, guarantees, and Commerce National's collateral position versus
other creditors. Historical loss information and local economic conditions are
considered in establishing allowances on the remaining portfolio. The allowance
is reduced by charging off loans deemed uncollectible by management. The
allowance is increased by provisions charged to expense and recoveries of
previous charge-offs. After a loan is charged off, collection efforts continue.
    
 
   
     While management of Commerce National places a strong emphasis on proper
loan underwriting and loan review procedures and has, to date, experienced low
levels of loan charge-offs, management has continued to increase its allowance
for loan losses due to its loan growth. Several factors make it more difficult
for Commerce National to quantify its allowance for loan losses than other
banks. These factors are as follows:
    
 
   
     - The overall age of Commerce National is still only 7 years, during which
       time the local economy has not experienced any significant recessionary
       periods;
    
 
   
     - Due to its small business focus, Commerce National's average loan size is
       much larger than other similarly sized banks.
    
 
   
     - Since its inception, Commerce National has grown substantially,
       especially the last 2 years and, typically, loan quality problems take at
       least several years to materialize; and
    
 
   
     - Commerce National's short history makes projecting loan losses based on
       historical experience less reliable than other banks, which is one of the
       measurement techniques utilized by the industry in assessing allowance
       for loan loss levels.

     The following tables set forth an allocation for the allowance for loan
losses by category of loan and the percentage of total loans configured by that
category. In making the allocation, consideration was given to such factors as
management's evaluation of risk in each category, current economic conditions
and charge-off experience. An allocation for the allowance for loan losses is an
estimate of the portion of the allowance that will be used to cover future
charge-offs in each major loan category, but it does not preclude any portion of
the allowance allocated to one type of loan being used to absorb losses of
another loan type.

NONPERFORMING ASSETS
 
     Nonperforming assets consist of loans on which interest is no longer
accrued, certain restructured loans where interest rate or other terms have been
renegotiated, accruing loans past due 90 days or more and real estate acquired
through foreclosure.
 
   
     CNBC discontinues the accrual of interest on loans that become 90 days past
due as to principal or interest unless they are adequately secured and in the
process of collection. A loan remains in a nonaccrual status until doubts
concerning collectibility no longer exist. A loan is classified as a
restructured loan when the interest rate is materially reduced or the term is
extended beyond the original maturity date because of the inability of the
borrower to service the loan under the original terms. Other real estate is
recorded at the lower of cost or fair value less estimated costs to sell.
    
 
     The following table sets forth information regarding non-accrual loans and
other nonperforming assets.

     The Board reviews all loans on non-accrual and all loans 90 days or more
delinquent on a monthly basis. The additional amount of interest income that
would have been recorded on non-accrual loans, had they been current, totaled
$11,800 and $7,400 for 1998 and 1997. In addition to the loans noted above,
management maintains a "watch" loan report to monitor the condition of borrowers
that exhibit certain weaknesses in their profitability or financial condition.
In the opinion of management, a total of $876,000 in watch loans could be
potential problem loans in the future.
 
   
SECURITIES PORTFOLIO
    
 
   
     Commerce National has maintained a loan to deposit ratio of approximately
97% since its inception. As a result, Commerce National's reliance on its
securities portfolio as a primary income source is lower relative to other
banks. Management stresses safety and liquidity with respect to its investment
decisions. Commerce National has maintained its portfolio in federal funds sold,
money market mutual funds, short term deposits with the Federal Home Loan Bank
and U.S. Treasury securities with maturities of less than two years. Management
foresees no significant change in its philosophy of safety and liquidity to
foster adequate liquidity for loan demand and unforeseen deposit withdrawal
needs.
    
 
   
     The following table sets forth certain information regarding the amortized
cost and carrying values of Commerce National's debt and equity and securities

DEPOSITS
    
 
   
     Since its inception, Bank management has followed a growth strategy which
was primarily driven by the amount of good quality loans which it could
responsibly fund. This strategy has resulted in loan growth which has outpaced
deposit growth from its primary customer base. Additionally, Commerce National's
primary
    
                                       28
<PAGE>   33
 
   
customer base has a strong preference for liquidity, which results in a
preference for short term Certificate of Deposit maturities and money market
savings accounts versus longer term Certificates of Deposit. As a result of
these factors, Commerce National has accepted Certificates of Deposit from
customers outside its designated market area which are solicited through a
national rate listing network. While only some of these deposits are placed
through a deposit broker, CNBC has elected to list all such funds as "Brokered
certificates of deposit" in the following table. Any brokerage fees or
commissions for such deposits are paid for by the depositor, not Commerce
National.
    
 
   
     Utilization of these deposits has the following benefits to Commerce
National:
    
 
   
     - Generates longer term funding for Commerce National not generally
       available from its primary customers;
    
 
   
     - Maintains Commerce National's efficiency due to accepting only deposits
       of $99,000 or greater; and
    
 
   
     - Permits Commerce National to fund loans at a higher growth rate than
       would otherwise have been feasible based on the deposit growth from its
       targeted customer base.
    
 
   
     The following table sets forth the distribution of CNBC's average deposit
accounts and the related weighted average interest rates on each category of
deposit presented at the dates indicated. CNBC has no deposits in foreign
banking offices.

                            DESCRIPTION OF PROPERTY
 
   
     CNBC and Commerce National are located at CNBC's only current facility at
100 East Wilson Bridge Road, Worthington, Ohio. Management has determined that
Commerce National is able to provide quality service to its customers from its
current location.
    
 
   
     Commerce National's main office is located in a 24,250 square foot general
purpose office building. Commerce National currently utilizes approximately 40%
of the building, with the remaining space leased by companies independent of
Commerce National. During early 1996, the previous owner of the building, in
accordance with a provision in Commerce National's lease, notified Commerce
National that the building was for sale and that Commerce National had the right
to make the first offer to buy the building. It was the consensus of the Board
of Directors and management of Commerce National that an offer should be made to
purchase the building. The purchase of the building was completed on June 1,
1997. Commerce National leased its space in the building from October 15, 1995
to June 1, 1997. Prior to October 15, 1995, Commerce National leased office
space in another building approximately 3 miles from its current location.

                           SUPERVISION AND REGULATION
 
   
     CNBC is a bank holding company subject to the supervision of and
examination by the Board of Governors of the Federal Reserve System under the
Bank Holding Company Act of 1956. As a bank holding company, CNBC must file an
annual report with the Board of Governors. The Board of Governors expects every
bank holding company to serve as a source of strength for its subsidiary banks.
    
 
   
     As a bank holding company subject to regulation by the Federal Reserve,
CNBC must comply with policy statements issued by the Federal Reserve. The
Federal Reserve policy statement governing payment of cash dividends provides
that a bank holding company should not pay cash dividends on common stock
unless:
    
 
   
     - the organization's net income for the past year is sufficient to fully
       fund the dividends, and
    
 
     - the prospective rate of earnings retention appears consistent with the
       organization's capital needs, asset quality and overall financial
       condition.
 
     Moreover, regulatory authorities are authorized to prohibit banks and bank
holding companies from paying dividends if payment of dividends would constitute
an unsafe and unsound banking practice.
 
     The Bank Holding Company Act requires every bank holding company to obtain
the prior approval of the Board of Governors before it may acquire substantially
all the assets of any bank, or ownership or control of any voting shares of any
bank, if, after such acquisition, it would own or control, directly or
indirectly, more than 5% of the voting shares of such bank.
 
                                       31
<PAGE>   36
 
     In addition, a bank holding company is generally prohibited from itself
engaging in, or acquiring direct or indirect control of voting shares of any
company engaged in nonbanking activities. One of the principal exceptions to
this prohibition is for activities found by the Board of Governors, by order or
regulation, to be so closely related to banking or managing or controlling banks
as to be a proper incident thereto.
 
   
     CNBC is an "affiliate" of Commerce National within the meaning of the
Federal Reserve Bank, which imposes restrictions upon:
    
 
   
     - loans by Commerce National to CNBC;
    
 
   
     - investments by Commerce National in the stock or the securities of CNBC;
       and
    
 
   
     - the use of CNBC common stock or securities of CNBC as collateral for
       loans by Commerce National to any borrower.
    
 
   
     Under current Federal Reserve guidelines, CNBC will be required to maintain
adequate capital in Commerce National. Commerce National's allowance for loan
losses and subordinated debt will be included subject to certain limitations and
intangible assets will be deducted in computing the level of Commerce National's
total capital. Commerce National is also subject to the capital adequacy
regulations of the Comptroller of the Currency. To be considered "adequately
capitalized," the required "leverage capital ratio" is 4%, the "tier 1
risk-based capital ratio" is 4%, and the "total risk-based capital ratio" is 8%.
To be "well capitalized," the foregoing requirements are 5%, 6%, and 10%,
respectively. Commerce National is considered to be "well capitalized" under the
foregoing standards. See Note 14 to the consolidated financial statements.
    
 
   
     The commercial banking business is affected not only by general economic
conditions, but also by the monetary policies of the Federal Reserve. Some of
the instruments of monetary policy available to the Federal Reserve:
    
 
   
     - changes in the discount rate on member bank borrowing,
    
 
     - availability of borrowing at the "discount window,"
 
     - open market operations,
 
     - the imposition of and changes in reserve requirements against member
       banks' deposits and assets of foreign branches, and
 
     - the changes in reserve requirements against certain borrowings by banks
       and their affiliates.
 
     These monetary policies influence to a significant extent the overall
growth of bank loans, investments, and deposits and the interest rates charged
on loans or paid on time and savings deposits.
 
   
     Commerce National is also subject to federal regulation as to such matters
as limitation as to the nature and amount of its loans and investments,
regulatory approval of any merger or consolidation, issuance or retirement by
Commerce National of its own securities and other aspects of banking operations.
In addition, the activities and operations of Commerce National are subject to a
number of additional detailed, complex and sometimes overlapping laws and
regulations. These include:
    
 
     - state usury and consumer credit laws,
 
     - state laws relating to fiduciaries,
 
     - the Federal Truth in Lending Act and Regulation Z,
 
   
     - the Real Estate Settlement and Procedures Act,
    
 
   
     - the Federal Equal Credit Opportunity Act and Regulation B,
    
 
   
     - the Federal Deposit Insurance Corporation Improvement Act of 1991,
    
 
   
     - the Fair Credit Reporting Act,
    
 
     - the Truth in Savings Act,
 
                                       32
<PAGE>   37
 
     - the Community Reinvestment Act,
 
     - anti-redlining legislation, and
 
     - antitrust laws.
 
   
     Commerce National is a nationally chartered bank and is subject to the
direct supervision and regulation and is regularly examined by the Office of the
Comptroller of the Currency. Additionally, Commerce National is a member of the
Federal Reserve System and its deposits are insured by the FDIC to applicable
limits. Areas of operation subject to regulation by federal laws, regulations
and regulatory agencies include:
    
 
     - terms on deposits,
 
     - investments,
 
     - loans,
 
     - fiduciary activities,
 
     - mergers,
 
     - issuance of securities,
 
     - payment of dividends,
 
     - establishment of branches, and
 
     - other aspects of operations.
 
   
     As noted in this Prospectus under the Section entitled "Deposits" and in
Note 7 to the Consolidated Financial Statements, Commerce National has relied on
brokered certificates of deposit as a significant funding source for its growth
and to help maintain a proper asset/liability GAP position. Current regulations
would require Commerce National to receive regulatory approval to continue to
accept brokered certificates if its capital level fell below the "well
capitalized" category. Additionally, Commerce National would be prohibited from
accepting brokered certificates if its capital level fell below the "adequately
capitalized" category.
    
 
   
     Commerce National is also subject to a variety of other laws that impose
limitations on loans to a single borrower, to insiders, and to others, and to
other laws which impose various requirements for certain types and classes of
loans.
    
 
   
     The earnings of Commerce National, as a lender of money, is affected by
legislative changes and by policies of various regulatory authorities which are
periodically reviewed and updated.
    
 
   
     New statutes and regulations, containing various plans for changes to the
structure, regulations and competitive relationships of the financial
institutions are regularly proposed. The Financial Services Competitiveness Act
will be re-introduced in the United States Congress this year. If adopted, this
legislation could significantly change the regulation of banks and the financial
services industry. Although some of the legislative and regulatory changes may
benefit us, others may increase our costs of doing business or have other
adverse effects on us and create competitive advantages for non-bank
competitors. We cannot predict whether the Financial Services Competitiveness
Act or any other legislation will be adopted or, if adopted, what effect these
would have.
    
 
     Under Ohio law, the Merger Moratorium Act, enacted in 1990, prohibits
certain Ohio corporations from engaging in specified types of transactions with
an "interested shareholder" for a period of three years after the shareholder
becomes an "interested shareholder" unless the shareholder receives the approval
of the corporation's Board of Directors prior to the acquisition of shares or
the consummation of the specified type of transaction. The anticipated effect of
the Merger Moratorium Act is to encourage a potential acquiror to negotiate with
a target corporation's Board of Directors prior to obtaining a 10 percent or
greater block of shares in the corporation.

EMPLOYMENT AGREEMENT
 
   
     Thomas D. McAuliffe, CNBC and Commerce National entered into an employment
agreement on March 1, 1998, as amended effective December 31, 1998, pursuant to
which Mr. McAuliffe serves as the President and CEO of CNBC and of Commerce
National. The employment agreement expires on February 28, 2003, subject to
extension by mutual agreement of the parties. The employment agreement provides
for an annual base salary of $140,000 per annum, subject to annual percentage
increases based upon increases in the diluted earnings per common share of CNBC,
and bonuses, which may be awarded in the sole discretion of the Boards of
Directors of CNBC and Commerce National. In addition, Commerce National
contributes $25,000 per year to a trust established by Commerce National as a
supplemental retirement benefit for Mr. McAuliffe's benefit.
    
 
   
     Mr. McAuliffe is eligible to participate in all retirement, welfare and
other benefit plans or programs of Commerce National to the same extent as other
Bank executive officers. In addition to any group life coverage, the employment
agreement provides for Commerce National to keep in place and pay premiums on a
life insurance policy on Mr. McAuliffe's life in the face amount of $2,000,000,
with respect to which Mr. McAuliffe may designate the beneficiary. Commerce
National also agrees to reimburse Mr. McAuliffe annually for any premiums paid
by him to maintain in force an individual disability income policy.
    
 
   
     The employment agreement terminates automatically upon Mr. McAuliffe's
death and at Commerce National's option, in the event of his disability. The
employment agreement is also terminable by Commerce National "with" or "without
cause" and Mr. McAuliffe may terminate the employment agreement "for good
reason" or "without good reason" or upon a "change in control." If Mr. McAuliffe
elects to terminate his employment following a "change in control," he is
entitled to his unpaid cash compensation through the date of termination, any
previously deferred compensation, accrued but unpaid vacation pay and severance
payments and benefit continuation over a one-hundred twenty (120) month period
based upon an agreed-upon formula. In the event Mr. McAuliffe's employment is
terminated by Commerce National "without cause" or by Mr. McAuliffe for "good
reason," he will be entitled to receive, in addition to accrued but unpaid
compensation and vacation pay, one year's worth of base salary and benefits plus
the amount then held in the trust. If Mr. McAuliffe's employment is terminated
by Commerce National "for cause" or by Mr. McAuliffe "without good reason," he
will only be entitled to receive his accrued (but unpaid) compensation and
vacation pay, along with any compensation previously deferred by him.
    
 
   
     The employment agreement provides that during a two (2) year period
following the termination of his employment with Commerce National, unless
terminated by Commerce National in the event of a disability, Mr. McAuliffe may
not compete or become associated with any entity that competes with the business
of CNBC or any of its subsidiaries in any geographic area where CNBC or any of
its subsidiaries operates an office. In addition, during the two (2) year period
referred to above (except by reason of a termination by Commerce National in the
event of a disability), Mr. McAuliffe may not directly or indirectly, encourage
or solicit, or assist any other person or firm in encouraging or soliciting
anyone having a business relationship with Commerce National or any of its
subsidiaries within the two (2) years preceding his termination of employment to
terminate a business relationship with Commerce National or engage in a business
relationship with a competitor.
    
 
EMPLOYEE STOCK OPTION PLANS
 
   
     In April, 1996, the shareholders of Commerce National adopted the 1996
Non-Qualified Stock Option Plan (the "Plan") providing for the grant of
non-qualified stock options to certain directors and key employees of Commerce
National and consolidating prior stock option plans. The exercise price of the
options granted under the Plan will not be less than the fair market value per
share of the common stock on the date of the grant.
    
 
     The options will be exercisable in whole or in part upon such terms and
conditions as may be determined by the Board of Directors but, in no event, will
options be exercisable later than 20 years after the date of grant. A total of
180,000 shares are approved for grant under the Plan.
 
   
     During 1998, Commerce National granted 5,950 stock options to employees. Of
this amount, executive officers received the following grants, all subject to a
3-year vesting period: Thomas D. McAuliffe -- 591; John
    
 
                                       37

A. Romelfanger -- 402 and Daniel M. Mahoney -- 361. All options granted to
executive officers had an exercise price of $28.00 per share and a 10-year
expiration.

COMMERCE NATIONAL BANK DEFERRED COMPENSATION PLANS
 
   
     Commerce National has a non-qualified deferred compensation plan for
directors. This plan permits the deferral of compensation earned until the
participant's retirement. The participant's election to defer compensation must
be made prior to the date the compensation is earned and all amounts deferred
earn interest.
    
 
   
     In addition to the plan for Mr. McAuliffe, described under employment
agreement, Commerce National has non-qualified compensation plans for three of
its senior officers. A plan for Mr. Romelfanger became effective on December 31,
1994. Plans for Mr. Mahoney and Ms. Miller were effective December 31, 1997. All
plans require the officers to remain in the employ of Commerce National for 10
years from the effective date to receive any benefits and are funded by life
insurance policies.
    
 
   
401(K) PLAN
    
 
   
     Commerce National has a trusteed 401(k) savings plan covering all employees
who have attained the age of 20 1/2 and work a minimum of 1,000 hours per
calendar year. Salary redirection or "401(k)" contributions are made to the plan
pursuant to a salary redirection agreement between each participant and Commerce
National. Commerce National makes a contribution for each participant equal to
three percent of the participant's compensation. In addition, a fifty (50)
percent match, on contributions up to a maximum of six (6) percent of the
participant's compensation, is made by Commerce National for those participants
who elect to make salary redirection contributions.
    
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
   
     The Board of Directors of Commerce National has established four
committees. These committees meet with management on a regularly scheduled basis
to review Commerce National's policies, procedures and operating performance on
particular functional areas. The activities of all committees are reviewed by
the Board
    
 
                                       38
<PAGE>   43
 
   
of Directors. These committees are established in accordance with the Bylaws of
Commerce National, which may be changed from time to time by a majority vote of
the Board of Directors.
    
 
   
     The Loan Committee is comprised of three directors, none of whom are
officers of Commerce National, and Mr. McAuliffe. The primary responsibilities
of the Committee are to review and approve loans over particular limits and
review and approve changes to Commerce National's lending policies and
procedures. All board members serve on the loan committee on a rotating basis.
The Committee met 26 times in 1998.
    
 
   
     The Funds Management Committee is comprised of not less than four outside
directors, Mr. McAuliffe, Mr. Romelfanger and Ms. Miller. The outside directors
currently serving on this committee include Mr. Gummer, Mr. Weiler, Mr. Ryan and
Mr. Canini. The Committee meets at least quarterly, and its primary
responsibilities include reviewing Commerce National's asset/liability interest
rate sensitivity, reviewing and approving investment policies and practices and
reviewing the operating performance of Commerce National. In 1998, the Committee
met 3 times.
    
 
   
     The Compensation Committee is comprised of at least five directors and Mr.
McAuliffe, who is a non-voting member, with its primary responsibility being the
review of personnel policies and practices and evaluation of senior management.
The directors currently serving on the committee include Mr. Corna, Mr. Ryan,
Mr. Tonti, Mr. Ruhl, Mr. Crane and Mr. McDaniel. The Committee met 4 times in
1998.
    
 
   
     The Audit Committee is comprised of at least four directors, none of whom
are officers of Commerce National. The Committee's primary responsibilities are
the review of internal and external auditors' reports, the review of internal
loan review reports, evaluation of the internal auditor and external audit firm,
and the review of regulatory examination results. The directors currently
serving on this committee include Mr. Canini, Mr. Hoy, Mr. Kenney and Ms.
DeVillers. The Committee met 4 times in 1998.
    
 
     Each outside director is paid an attendance fee of $250 per Board of
Directors meeting and $100 per committee meeting.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
   
     Directors and officers of CNBC and their associates are customers of, and
have had transactions with, Commerce National in the ordinary course of
business. All outstanding loans and commitments included in such transactions
were made on substantially the same terms, including interest rates and
collateral, as those prevailing at the time for comparable transactions with
other persons and, in the opinion of management, did not involve more than the
normal risk of collectibility or present other unfavorable features.
    
 
   
     At December 31, 1998, the aggregate amount of extensions of credit from
Commerce National to directors and executive officers of CNBC and their
respective associates is as follows:

     Additionally, the directors and executive officers maintained deposit
account relationships with Commerce National totaling $9,350,000 at December 31,
1998. The loan and deposit balances are more substantial than other financial
institutions of similar size due to the fact that many of the directors are
founding organizers of Commerce National and CNBC's board is approximately twice
the size of most similar sized financial institutions. See Note 5 to the
Consolidated Financial Statements attached hereto.

                           DESCRIPTION OF SECURITIES
 
GENERAL
 
   
     The authorized capital stock of CNBC consists of 2,000,000 common shares,
no par value, of which 1,116,972 shares were outstanding as of December 31, 1998
and beneficially owned by approximately 400 shareholders. Upon completion of
this offering, CNBC will have up to 1,241,972 common shares outstanding. The
authorized capital stock of CNBC also consists of 200,000 shares of Serial
Preferred Stock, par value $10.00. No shares of Serial Preferred Stock are
issued and outstanding.
    
 
VOTING RIGHTS
 
   
     The holders of common shares are entitled to one vote per share on all
matters submitted to a vote of shareholders, except in the election of
directors, for which the common shares have cumulative voting rights.
    
 
DIVIDENDS
 
   
     CNBC's current policy is to declare dividends semi-annually in June and
December. Although CNBC intends to continue to pay cash dividends on its common
shares in the future based upon its net income and available cash flow, there
can be no assurance that CNBC will have earnings sufficient to pay a dividend on
its common shares or that, even if there are sufficient earnings, dividends will
be permitted under applicable laws or regulatory requirements.
    
 
COMMON SHARES FULLY PAID AND NONASSESSABLE
 
   
     All of the outstanding common shares of CNBC are, and the common shares to
be sold by CNBC pursuant to this offering when issued will be validly issued,
fully paid and nonassessable.
    
 
PREEMPTIVE RIGHTS/REPURCHASE AND REDEMPTION
 
   
     Shareholders of CNBC do not have preemptive rights to purchase or subscribe
to any shares or other securities of CNBC. The Board of Directors may authorize
CNBC at any time to purchase or redeem shares issued by CNBC to the extent of
available surplus.
    
 
SPECIAL VOTE FOR CONTROL SHARE ACQUISITIONS
 
   
     Under the Ohio General Corporate Law, unless a corporation's articles of
incorporation or regulations provide otherwise, any "control share acquisition"
of an "issuing public corporation" can be made only with the prior authorization
of the corporation's shareholders in accordance with the Ohio Control Share
Acquisition Statute (the "Statute"). As an alternative, an Ohio corporation may
include in its articles of incorporation or regulations restrictions on transfer
of its shares in connection with a "control share acquisition," including
procedures for obtaining the consent of shareholders and for the screening by
directors of proposals for such acquisitions. CNBC's Articles provide that the
Statute does not apply to it. Specifically, Article Sixth sets forth a procedure
for obtaining shareholder consent that is consistent with the Statute, subject
to the right of directors to screen out proposals that do not meet certain
standards set forth in Article Sixth of the Articles. The right of the Board of
Directors to screen control share acquisitions is the principal difference
between Article Sixth and the requirements of Ohio law which would otherwise be
applicable to CNBC.
    
 
   
     A "control share acquisition" is defined in Article Sixth of the Articles
as any acquisition, whether by tender offer, open market purchase, privately
negotiated transaction or otherwise (with certain limited exceptions), of CNBC
common shares which, when added to all other CNBC common shares owned or
controlled by the acquiror, would entitle the acquiror to exercise or direct the
exercise of voting power in the election of directors within any of the
following ranges of voting power:
    
 
   
          (a) one-fifth or more but less than one-third;
    
 
   
          (b) one-third or more but less than a majority; and
    
 
   
          (c) a majority or more.
    
 
                                       41
<PAGE>   46
 
   
     Article Sixth requires that a person proposing to make a control share
acquisition deliver a written notice to CNBC describing, among other things, the
terms of the proposed acquisition and giving reasonable evidence that the
proposed control share acquisition would not be contrary to law and that the
person who gave the notice has the financial capacity to make such an
acquisition. CNBC is required to call and hold, within fifty (50) days after
receipt of the notice, a special meeting of shareholders to vote on the proposed
control share acquisition. However, the Board of Directors has no obligation to
call such a meeting if it determines that (i) the notice was not given in good
faith, (ii) the proposed control share acquisition would not be in the best
interests of CNBC and its shareholders, or (iii) the proposed control share
acquisition could not be consummated for financial or legal reasons.
Notwithstanding the exception in clause (ii) of the preceding sentence, the
Board of Directors is not able to refuse to call such a meeting of shareholders
for the reason stated in clause (ii) if the proposed control share acquisition
is for any and all CNBC common shares at a price higher than 250% of the book
value of CNBC common shares as of the last day of the preceding fiscal year.
    
 
   
     Article Sixth provides that a determination by the Board of Directors not
to call such a meeting will not be deemed void or voidable with respect to CNBC
merely because one or more directors who participate in making the determination
might be deemed to be other than "disinterested directors," if in any such case
the material facts of the relationship giving rise to a basis for self-interest
are known to the directors participating in the determination, and such
directors, in good faith reasonably justified by the facts, make such
determination by a majority of the "disinterested directors." For these
purposes, a "disinterested director" means a director whose material contacts
with CNBC are limited principally to activities as a director, a shareholder, a
customer or a depositor of CNBC or any of its subsidiaries or affiliates.
However, a director would not be deemed to be other than a "disinterested
director" merely because he would no longer be a director if the proposed
control share acquisition were approved and consummated.
    
 
   
     The notice to shareholders of the special meeting must include or be
accompanied by both the acquiring person's notice and a statement by the CNBC
Board of Directors of its position or recommendation with respect to such
acquisition or a statement that no position is being taken or recommendation
being made.
    
 
   
     Approval of a control share acquisition requires the affirmative vote of
both (i) a majority of the voting power represented at the meeting and (ii) a
majority of that portion of such voting power excluding any "interested
shares" -- that is, those shares held by the acquiring person and certain
officers and directors of CNBC.
    
 
   
     As drafted, Article Sixth also provides that proxies (which are otherwise
irrevocable if coupled with an interest) given in connection with a control
share acquisition are revocable at any time prior to obtaining the requisite
shareholder vote.
    
 
   
     Each CNBC stock certificate will have a legend stating that such shares are
subject to the provisions of Article Sixth. The issuance or transfer of shares
in violation of Article Sixth will be null and void. In the event CNBC is not
permitted to treat an issuance or transfer of shares in violation of Article
Sixth as null and void, Article Sixth provides that such shares will be treated
as treasury shares, not entitling the holder to exercise shareholder rights or
receive dividends.
    
 
   
     The Articles establish the concept of a majority vote to adopt amendments
to the Articles but require the affirmative vote of seventy-five percent (75%)
of the voting shares to amend Article Sixth described above (relating to control
share acquisitions) or to adopt provisions having the effect of amending those
provisions of the Regulations dealing with the number, classification and
removal of directors, which are more fully described below.
    
 
TRANSFER AGENT AND REGISTRAR
 
   
     CNBC acts as its own transfer agent and registrar.
    
 
   
CERTAIN PROVISIONS OF CNBC'S ARTICLES OF INCORPORATION AND CODE OF REGULATIONS
    
 
   
     CNBC's Articles of Incorporation provide for a classified Board of
Directors. The directors are divided into three classes as nearly equal in
number as possible, and each class is elected for a staggered three-year term of
    
                                       42
<PAGE>   47
 
office at each annual shareholders meeting. If the number of directors is
changed, any increase or decrease shall be apportioned among the classes so as
to maintain the number of directors in each class as nearly equal as possible,
and any additional director of any class elected to fill a vacancy resulting
from an increase in such class, but in no case will a decrease in the number of
directors shorten the term of any incumbent director. A director shall hold
office until the annual meeting for the year in which his term expires and his
successor shall be elected and shall qualify; subject, however, to prior death,
resignation, or removal from office.
 
   
     Article Fourth of CNBC's Articles authorizes 200,000 Serial Preferred
Shares ("Serial Shares"), all with a par value of Ten Dollars ($10.00), which
may be issued in one or more series by the Board of Directors. The Board of
Directors is authorized by the Articles to establish, among other things,
dividend rates, cumulative rights, redemption rights or prices, sinking fund
provisions, and conversion rights of the Serial Shares. The holders of Serial
Shares are entitled to be paid dividends when and as declared in preference to
the holders of the common shares. In liquidation or dissolution, the holders of
Serial Shares are entitled to be paid for their shares, plus the amount of any
dividends in arrears, before any amounts are paid to the holders of the common
shares in respect of such Shares. The holders of the Serial Shares are entitled
to one vote per share on all matters presented to the shareholders. Except as
indicated below, the holders of Serial Shares vote with the holders of the
common shares on matters presented to the shareholders. If there is a default in
respect of six quarterly dividends, the holders of the Serial Shares are
entitled to elect two directors to the Board of Directors until such default is
cured. The affirmative vote of the holders of two-thirds of the outstanding
Serial Shares, voting separately as a class, is required to adopt any amendment
to the Articles or Regulations (i) to authorize any class of stock ranking on a
parity with outstanding Serial Shares or to increase the authorized number of
Serial Shares or (ii) to authorize the sale of substantially all of the assets
of CNBC or certain mergers.
    
 
   
     In the event of a tender offer or other attempt to gain control of CNBC
that the Board of Directors does not approve, it would be possible for the Board
of Directors to authorize the issuance of a series of Serial Shares with rights
and preferences that could impede the completion of such a transaction. The
flexibility of the Board of Directors to take such action will be increased by
virtue of the denial of preemptive rights. However, CNBC does not at present
have any plans, arrangements, commitments or understandings to issue any Serial
Shares. Any Serial Shares issued in the future will be on terms which the Board
of Directors deems to be in the best interests of CNBC and its shareholders.
    
 
   
     Under CNBC's Regulations, a special meeting of shareholders may be called
by the President, a Vice President or a majority of the Board of Directors, and
by shareholders holding a requisite percentage of the shares entitled to vote.
With respect to special meetings called by shareholders, the Regulations provide
that the requisite percentage for calling such meetings is fifty percent (50%).
This provision is consistent with the maximum permissible requirement under Ohio
law.
    
 
   
     The Regulations establish a requirement that advance notification of
nominations of directors by shareholders be given to the Secretary of CNBC, as a
general rule, not less than sixty (60) nor more than ninety (90) days prior to
the date of any shareholders' meeting (as initially called, in the case of
adjourned meetings) held for the purpose of electing directors. If less than
seventy-five (75) days notice or prior public disclosure of a meeting date is
given or made to the shareholders, in order to be timely, the shareholders'
notice must be received by the close of business on the fifteenth day following
the earlier of the day the meeting notice was mailed or public disclosure of the
meeting was made. The notice of nomination must set forth certain information
regarding each nominee who is not an incumbent director and must be accompanied
by the written consent of the proposed nominee to serve as a director if
elected. Nominations which the chairman of the meeting determines not to have
been made in accordance with the Regulations are to be disregarded.
    
 
   
     A similar provision applies to business that may be brought before a
meeting of shareholders by a shareholder. CNBC Regulations provide that a
shareholder must give the Secretary written notice that a matter is to be
brought before such a meeting, as a general rule, not less than sixty (60) nor
more than ninety (90) days prior to the date of the meeting (as initially
called, in the case of adjourned meetings). If less than seventy-five (75) days
notice or prior public disclosure of a meeting date is given or made to the
shareholders, in order to be timely, the shareholders' notice must be received
by the close of business on the fifteenth day following the earlier of the day
the meeting notice was mailed or public disclosure of the meeting was made. The
notice must
    
 
                                       43
<PAGE>   48
 
contain, among other things, a brief description of the business the shareholder
desires to bring before the meeting, the reasons thereof and any material
interest of such shareholder in such business.
 
     The purpose of these nomination and shareholder proposal procedures is to
avoid the possibility of nominations or proposals being made in a way that would
preclude the Board from investigating and the shareholders from adequately
assessing the competence, experience, integrity and other relevant factors
concerning the qualifications of a proposed nominee or any relevant factors
concerning shareholder proposals. The Board of Directors believes that matters
should be brought before a meeting in an orderly fashion and in sufficient time
before a meeting so that shareholders may be provided adequate information in
order to vote on a fully-informed basis.
 
   
     The provisions described above could deter a shareholder from gaining
control of CNBC by means of making nominations for directors or proposing
shareholder actions from the floor of a meeting or by means of a proxy contest
instituted so close to the date of a shareholders' meeting that adequate
information might not be available to shareholders.
    
 
   
     A possible adverse effect of the nomination and shareholder proposal
provisions may be that persons otherwise qualified to serve as directors and who
are proposed for nomination and election by holders of a majority of the
outstanding voting shares may not be nominated or elected due to inadvertence or
otherwise. Also, this provision may make it easier for incumbent directors to
solicit proxies to resist a dissident slate of directors and thus retain their
status as directors, even when the dissident nominations might be in the best
interests of CNBC and its shareholders. In this sense, the provisions can be
viewed as advantageous to incumbent directors and executive officers and may
discourage takeover attempts.
    
 
                      DISCLOSURE OF COMMISSION POSITION ON
                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES
 
   
     Section 1701.13 of the Ohio Revised Code provides for the indemnification
of officers and directors against liability and certain expenses that may be
incurred by them in the event of an action against them as a result of their
service for or on behalf of CNBC. The Code of Regulations of CNBC contains
specific provisions in regard to indemnification of officers and directors of
CNBC and its subsidiaries to implement the general provisions of such section.
Furthermore, to enable CNBC to continue to attract and retain qualified
directors and officers, CNBC has entered into indemnification agreements with
each director and officer of CNBC that specify the types of matters for which
indemnification by CNBC is available and the extent of indemnification afforded
and provide for advancement of defense expenses under certain conditions.
    
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
   
     The market price of the common shares could drop as a result of sales of a
large number of common shares in the market after the offering, or the
perception that such sales could occur. These factors could also make it more
difficult for CNBC to raise funds through future offerings. As a result of the
offering, there will be an additional 125,000 Company common shares outstanding.
All of these shares will be freely transferable without restriction of future
registration, except for any common shares purchased by "affiliates" of CNBC, as
defined in Rule 144 under the Securities Act. The remaining 1,116,972
outstanding common shares of CNBC, which have been issued in private offerings
or are issuable upon the exercise of warrants, are "restricted securities" as
defined in Rule 144 and may be resold without restriction to the extent
permitted by Rule 144 or an exemption under the Securities Act. It should be
noted that the holding period restrictions on the majority of the 1,116,972
shares have lapsed. Assuming the offering is fully subscribed for, CNBC will
have 522,348 authorized but unissued shares which may be issued without further
approval of its shareholders.
    
 
                               LEGAL PROCEEDINGS
 
   
     Neither CNBC nor Commerce National is a party to any material pending legal
proceedings.

                         REPORT OF INDEPENDENT AUDITORS
 
To the Board of Directors and the Shareholders
of CNBC Bancorp:
 
   
     We have audited the accompanying consolidated balance sheets of CNBC
Bancorp as of December 31, 1998 and 1997, and the related consolidated
statements of income, comprehensive income, changes in shareholders' equity and
cash flows for the years then ended. These financial statements are the
responsibility of CNBC Bancorp'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 consolidated financial statements referred to above
present fairly, in all material respects, the financial position of CNBC Bancorp
as of December 31, 1998 and 1997, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

                 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
    
 
   
                           DECEMBER 31, 1998 AND 1997
    
 
   
NOTE 1 -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
    
 
   
     The following is a summary of the significant accounting policies followed
in the preparation of the financial statements.
    
 
   
     BASIS OF PRESENTATION: The consolidated financial statements include the
accounts of CNBC Bancorp ("Bancorp") and its wholly owned subsidiary, Commerce
National Bank ("Bank"). All significant intercompany balances and transactions
have been eliminated in consolidation.
    
 
   
     NATURE OF OPERATIONS: Revenues and assets are derived from the banking
industry, serving primarily small business customers in the central Ohio region.
Banking deposit products include checking and savings accounts and certificates
of deposit. Business loans are secured by real estate, accounts receivable,
inventory, equipment and other types of collateral and are expected to be repaid
from cash flows from operations of businesses. Personal loans are secured by
real estate, stocks and other collateral. A small portion of loans are
unsecured. All of Bancorp's banking operations are considered by management to
be aggregated in one reportable operating segment.
    
 
   
     USE OF ESTIMATES: To prepare financial statements in conformity with
generally accepted accounting principles, management makes certain estimates and
assumptions based on available information. These estimates and assumptions
affect the amounts reported in the financial statements and the disclosures
provided. Future results could differ from these estimates. The allowance for
loan losses, fair values of financial instruments and status of contingencies
are more susceptible to change.
    
 
   
     SECURITIES: Securities can be classified into held to maturity, available
for sale, and trading categories. Held to maturity securities are those which
management has the positive intent and ability to hold to maturity, and are
reported at amortized cost. Available for sale securities are those which may be
sold prior to maturity for liquidity, asset-liability management, or other
reasons. Available for sale securities are reported at fair value, with
unrealized gains or losses reported in other comprehensive income. Trading
securities are bought principally for sale in the near term and are reported at
fair value with unrealized gains or losses included in earnings. Realized gains
or losses are determined based on the amortized cost of the specific security
sold. Interest income includes amortization of purchase premium or discount.
Securities are written down to fair value when a decline in fair value is not
temporary.
    
 
   
     LOANS: Loans are reported at the principal balance outstanding, net of
deferred loan fees and costs and the allowance for loan losses. Interest income
on loans is recognized on the interest method and includes amortization of net
deferred loan fees and costs over the loan term. The accrual of interest on
loans will be suspended when, a loan is 90 days or more past due unless the loan
is well collateralized or in the process of collection. When a loan is placed on
nonaccrual status, accrued and unpaid interest at risk is charged against
income. Payments received on nonaccrual loans will be applied against principal
until recovery of the remaining balance is reasonably assured.
    
 
   
     ALLOWANCE FOR LOAN LOSSES: The allowance for loan losses is a valuation
allowance for probable credit losses increased by recording a provision for loan
losses, which is charged to current expense, and receiving recoveries on loans
previously charged-off. The allowance for loan losses is decreased by loan
charge-offs. Management's periodic evaluation of the adequacy of the allowance
is based on known and inherent risks in the nature and volume of the loan
portfolio, assessment of individual borrower's ability to repay their loans
including the value of any collateral, current economic conditions, and past
loan loss experience. Many of these factors are subjective and may change over
time. Allocations of the allowance may be made for specific loans, but the
entire allowance is available for any loan that, in management's judgment,
should be charged-off. A loan is classified as impaired when full payment under
the loan terms is not expected. Impairment is evaluated in total for smaller
balance loans or loans of a similar nature such as residential mortgage and
credit card loans, and on an individual

basis for other loans. Loans considered to be impaired are reduced to the
present value of expected future cash flows, or to the fair value of collateral
securing the loan if repayment is expected solely from the collateral, by
allocating a portion of the allowance for loan losses to such loans. Loans are
evaluated for impaired status when payments are past due 90 days or more or when
management's grading system indicates a doubtful classification. Interest
received on impaired loans that are not on nonaccrual status is recorded as
interest income.
    
 
   
     CONCENTRATION OF CREDIT RISK: Business and real estate investment loans
comprised approximately 78 percent and 75 percent of total loans at December 31,
1998 and 1997, respectively.
    
 
   
     PREMISES AND EQUIPMENT: Asset cost is reported net of accumulated
depreciation. Depreciation is computed on the straight-line method over the
estimated useful life of the asset. Maintenance and repairs are charged to
expense as incurred, and major improvements are capitalized. Assets are reviewed
for impairment when events indicate the carrying amount may not be recoverable.
    
 
   
     EMPLOYEE BENEFITS: A trusteed 401(k) savings plan covers all employees who
have attained the age of 20 1/2 and work a minimum of 1,000 hours per calendar
year. An employer contribution for each participant equal to three percent of
the participant's compensation is made annually. The plan also allows employee
contributions, with contributions up to six percent of the participant's
compensation matched 50 percent by the employer. Expense related to the plan was
$84,200 and $60,400 in 1998 and 1997. No post-retirement benefits other than the
401(k) plan are provided to employees.
    
 
   
     STOCK COMPENSATION: Expense for employee compensation under the stock
option plan is recorded only if options are granted below the market value of
the stock on the grant date. Pro forma disclosures of net income and earnings
per share are shown using the fair value method of SFAS No. 123 to measure
expense for options granted after 1994, using an option pricing model to
estimate fair value.
    
 
   
     INCOME TAXES: Income tax expense is the sum of the current year income tax
due or refundable and the change in deferred tax assets and liabilities.
Deferred tax assets and liabilities are the expected future tax consequences of
temporary differences between the carrying amounts and tax bases of assets and
liabilities, computed using enacted tax rates. A valuation allowance, if needed,
reduces deferred tax assets to the amount expected to be realized.
    
 
   
     EARNINGS PER SHARE: Bancorp adopted Statement of Financial Accounting
Standards ("SFAS") No. 128 on December 31, 1997 which requires dual presentation
of basic and diluted earnings per share ("EPS"). Basic EPS is net income divided
by the weighted-average number of common shares outstanding. Diluted EPS is the
weighted-average number of common shares outstanding during the year and the
assumed exercise of dilutive stock options and warrants less the number of
treasury shares assumed to be purchased from the proceeds using the average
market price of Bancorp's common stock. The calculation for weighted average
shares is as follows:

     On May 1, 1997, Bancorp borrowed $2,000,000 from another financial
institution. The proceeds were utilized to purchase subordinated notes of
Commerce National Bank. The interest rate on the loan adjusts every 90 days for
the first two years at 2.50 percent over the 90-day U.S. Treasury bill rate. The
interest rate on the loan was 6.45 percent and 7.60 percent at December 31, 1998
and 1997. Only interest payments are required for the first two years. On May 1,
1999, the rate will adjust to a fixed interest rate of 2.50 percent over the
5-year U.S. Treasury note rate and Bancorp will be required to make equal
monthly principal and interest payments calculated on a 96-month amortization.
The loan is unsecured; however, Bancorp has agreed not to pledge its ownership
interest in Commerce National Bank stock during the term of the loan.
    
 
   
     Additionally, a $4 million cash management advance revolving line of credit
was approved with the FHLB. At December 31, 1998 and 1997, no advances were
outstanding on the line. Available collateral for all FHLB advances totaled
$39,120,000 and $33,953,000 at December 31, 1998 and 1997 and consists of a
blanket pledge of all first mortgage loans secured by 1-4 family residential
properties and all FHLB stock.

NOTE 12 -- 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 financial condition or results of operations.
    
 
   
     At December 31, 1998 and 1997, reserves of $1,061,000 and $915,000 were
required as deposits with the Federal Reserve or as cash on hand. These reserves
do not earn interest.
    
 
   
     Some financial instruments are used in the normal course of business to
meet the financing needs of customers and to reduce exposure to interest rate
changes. These financial instruments include commitments to extend credit and
standby letters of credit. These involve, to varying degrees, credit and
interest-rate risk in excess of the amount reported in the financial statements.
    
 
   
     Exposure to credit loss if the other party does not perform is represented
by the contractual amount for commitments to extend credit, standby letters of
credit, and financial guarantees written. The same credit policies are used for
commitments and conditional obligations as are used for loans.
    
 
   
     Commitments to extend credit are agreements to lend to a customer as long
as there is no violation of any condition established in the commitment.
Commitments generally have fixed expiration dates or other termination clauses
and may require payment of a fee. Some of the commitments are expected to expire
without being used;

therefore, the total commitments does not necessarily represent future cash
requirements. Standby letters of credit and financial guarantees written are
conditional commitments to guarantee a customer's performance to a third party.

     For purposes of the above disclosures of estimated fair value, the
following assumptions were used. The estimated fair value for cash and cash
equivalents is considered to approximate cost. The estimated fair value for
securities is based on quoted market values for the individual securities or for
equivalent securities. Carrying value is considered to approximate fair value
for accrued interest receivable, for deposit liabilities subject to immediate
withdrawal, and for accrued interest payable. The fair values of loans, time
deposits, and borrowings are approximated by calculating the sum of the carrying
value for amounts that contractually reprice at intervals less than six months
and the present value of cash flows using an estimated market discount interest
rate for amounts that reprice less frequently than every six months. The fair
values of unrecorded commitments at December 31, 1998 and 1997 are not material.

     While these estimates are based on management's judgment of the appropriate
evaluation factors, there is no assurance that were such items liquidated the
estimated fair values would necessarily have been realized. The estimated fair
values should not be considered to apply at subsequent dates.
    
 
   
NOTE 14 -- REGULATORY MATTERS
    
 
   
     The Bank and Bancorp are subject to regulatory capital requirements
administered by federal banking agencies. Capital adequacy guidelines and,
additionally for banks, 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 adequately capitalized
requirements could result in regulatory action that could have a direct material
effect on the financial statements.
    
 
   
     The Office of the Comptroller of the Currency ("OCC") must approve the
declaration of any dividends for the Bank in excess of available retained
earnings and in excess of the sum of profits for the year combined with the
Bank's retained earnings from the two preceding years, less any required
transfer to surplus. In addition, dividends may not reduce capital levels below
the minimum regulatory requirements disclosed above. Under the most restrictive
of these requirements, Bancorp estimates retained earnings available for payment
of dividends by the Bank to Bancorp approximates $800,000 in order to maintain
the well capitalized status at year-end 1998.
    
 
   
     The prompt corrective action regulations provide five regulatory capital
classifications: well capitalized, adequately capitalized, undercapitalized,
significantly undercapitalized and critically undercapitalized. These terms are
not intended to represent overall financial condition. The Bank met the
requirements of a well capitalized institution as defined above, at December 31,
1998 and 1997. If the Bank's capital classification were to change to adequately
capitalized, it would need to obtain regulatory approval to continue to accept
brokered deposits.
    
 
   
     Actual and required capital amounts and ratios are presented below at
year-end. During 1998, Bancorp's consolidated assets surpassed $150 million for
the first time. As a result, the Federal Reserve will monitor the consolidated
capital position of Bancorp in addition to the capital position of the Bank.

   FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING (See the instructions on page
   2.)
 
                                 CERTIFICATION
 
Under penalties of perjury, I certify that:
 
1. The number shown on this form is my correct taxpayer identification number
   (or I am waiting for a number to be issued to me) and
 
2. I am not subject to backup withholding because: (a) I am exempt from backup
   withholding, or (b) I have not been notified by the Internal Revenue Service
   (IRS) that I am subject to backup withholding as a result of a failure to
   report all interest or dividends, (c) the IRS has notified me that I am no
   longer subject to backup withholding.
 
CERTIFICATION INSTRUCTIONS. -- You must cross out item 2 above if you have been
notified by the IRS that you are currently subject to backup withholding because
you have failed to report all interest and dividends on your tax return. For
real estate transactions, item 2 does not apply. For mortgage interest paid,
acquisition or abandonment of secured property, cancellation of debt,
contributions to an individual retirement arrangement (IRA), and generally,
payments other than interest and dividends, you are not required to sign the
Certification, but you must provide your correct TIN. (See the instructions on
page 2.)

PURPOSE OF FORM. -- A person who is required to file an information return with
the IRS must get your correct taxpayer identification number (TIN) to report,
for example, income paid to you, real estate transactions, mortgage interest you
paid, acquisition or abandonment of secured property, cancellation of debt, or
contributions you made to an IRA.
 
    Use Form W-9 to give your correct TIN to the person requesting it (the
requester) and, when applicable, to:
 
    1. Certify the TIN you are giving is correct (or you are waiting for a
number to be issued),
 
    2. Certify you are not subject to backup withholding, or
 
    3. Claim exemption from backup withholding if you are an exempt payee.
 
NOTE: If a requester gives you a form other than a W-9 to request your TIN, you
must use the requester's form if it is substantially similar to this Form W-9.
 
WHAT IS BACKUP WITHHOLDING? -- Persons making certain payments to you must
withhold and pay to the IRS 31% of such payments under certain conditions. This
is called "backup withholding." Payments that may be subject to backup
withholding include interest, dividends, broker and barter exchange
transactions, rents, royalties, nonemployee pay, and certain payments from
fishing boat operators. Real estate transactions are not subject to backup
withholding.
 
    If you give the requester your correct TIN, make the proper certifications,
and report all your taxable interest and dividends on your tax return, payments
you receive will not be Subject to backup withholding. Payments you receive WILL
be subject to backup withholding if:
 
    1. You do not furnish your TIN to the requester, or
 
    2. The IRS tells the requester that you furnished an incorrect TIN, or
 
    3. The IRS tells you that you are subject to backup withholding because you
did not report all your interest and dividends on your tax return (for
reportable interest and dividends only), or
 
    4. You do not certify to the requester that you are not subject to backup
withholding under 3 above (for reportable interest and dividend accounts opened
after 1983 only), or
 
    5. You do not certify your TIN when required. See the Part III instructions
on page 2 for details.
 
    Certain payees and payments are exempt from backup withholding. See the Part
II instructions and the separate INSTRUCTIONS FOR THE REQUESTER OF FORM W-9.
 
                                   PENALTIES
 
FAILURE TO FURNISH TIN. -- IF you fail to furnish your correct TIN to a
requester, you are subject to a penalty of $50 for each such failure unless your
failure is due to reasonable cause and not to willful neglect.
 
CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. -- If you make
a false statement with no reasonable basis that results in no backup
withholding, you are subject to a $500 penalty.
 
CRIMINAL PENALTY FOR FALSIFYING INFORMATION. -- Willfully falsifying
certifications or affirmations may subject you to criminal penalties including
fines and/or imprisonment.
 
MISUSE OF TINS. -- If the requester discloses or uses TINs in violation of
Federal law, the requester may be subject to civil and criminal penalties.

                             SPECIFIC INSTRUCTIONS
 
NAME. -- If you are an individual, you must generally enter the name shown on
your social security card. However, if you have changed your last name, for
instance, due to marriage, without informing the Social Security Administration
of the name change, enter your first name, the last name shown on your social
security card, and your new last name.
 
If the account is in joint names, list first and then circle the name of the
person or entity whose number you enter in Part I of the form.
 
Sole Proprietor. -- You must enter your INDIVIDUAL name as shown on your social
security card. You may enter your business, trade, or "doing business as" name
on the BUSINESS NAME line.
 
Other Entities. -- Enter the business name as shown on required Federal tax
documents. This name should match the name shown on the charter or other legal
document creating the entity. You may enter any business, trade, or "doing
business as" name on the business name line.
 
                 PART I -- TAXPAYER IDENTIFICATION NUMBER (TIN)
 
You must enter your TIN in the appropriate box. If you are a resident alien and
you do not have and are not eligible to get an SSN, your TIN is your IRS
individual taxpayer identification number (ITIN). Enter it in the social
security number box. If you do not have an ITIN, see HOW TO GET A TIN below.
 
If you are a sole proprietor and you have an EIN, you may enter either your SSN
or EIN. However, using your EIN may result in unnecessary notices to the
requester.
 
NOTE: See the chart on this page for further clarification of name and TIN
combinations.
 
HOW TO GET A TIN. -- IF you do not have a TIN, apply for one immediately. To
apply for an SSN, get FORM SS-5 from your local Social Security Administration
office. Get FORM W-7 to apply for an ITIN or FORM SS-4 to apply for an EIN. You
can get Forms W-7 and SS-4 from the IRS by calling 1-800-TAX-FORM
(1-800-829-3676).
 
IF you do not have a TIN, write "Applied For" in the space for the TIN, sign and
date the form, and give it to the requester. For interest and dividend payments,
and certain payments made with respect to readily tradable instruments, you will
generally have 60 days to get a TIN and give it to the requester. Other payments
are subject to backup withholding.
 
NOTE: Writing "Applied For" means that you have already applied for a TIN OR
that you intend to apply for one soon.
 
              PART II -- FOR PAYEES EXEMPT FROM BACKUP WITHHOLDING
 
Individuals (including sole proprietors) are NOT exempt from backup withholding.
Corporations are exempt from backup withholding for certain payments, such as
interest and dividends. For more information on exempt payees, see the separate
Instructions for the Requester of Form W-9.
 
If you are exempt from backup withholding, you should still complete this form
to avoid possible erroneous backup withholding. Enter your correct TIN in Part
I, write "Exempt" in Part II, and sign and date the form.
 
    IF you are a nonresident alien or a foreign entity not subject to backup
withholding, give the requester a completed FORM W-8, Certificate of Foreign
Status.
 
                           PART III -- CERTIFICATION
 
    For a joint account, only the person whose TIN is shown in Part I should
sign (when required).
 
    1. INTEREST, DIVIDEND, AND BARTER EXCHANGE ACCOUNTS OPENED BEFORE 1984 AND
BROKER ACCOUNTS CONSIDERED ACTIVE DURING 1983. You must give your correct TIN,
but you do not have to sign the certification.
 
    2. INTEREST, DIVIDEND, BROKER, AND BARTER EXCHANGE ACCOUNTS OPENED AFTER
1983 AND BROKER ACCOUNTS CONSIDERED INACTIVE DURING 1983. You must sign the
certification or backup withholding will apply. IF you are subject to backup
withholding and you are merely providing your correct TIN to the requester, you
must cross out item 2 in the certification before signing the form.
 
    3. REAL ESTATE TRANSACTIONS. You must sign the certification. You may cross
out item 2 of the certification.
 
    4. OTHER PAYMENTS. You must give your correct TIN, but you do not have to
sign the certification unless you have been notified that you have previously
given an incorrect TIN. "Other payments" include payments made in the course of
the requester's trade or business for rents, royalties, goods (other than bills
for merchandise), medical and health care services (including payments to
corporations), payments to a nonemployee for services (including attorney and
accounting fees), and payments to certain fishing boat crew members.
 
    5. MORTGAGE INTEREST PAID BY YOU, ACQUISITION OR ABANDONMENT OF SECURED
PROPERTY, CANCELLATION OF DEBT, OR IRA CONTRIBUTIONS. You must give your correct
TIN, but you do not have to sign the certification.
 
                               PRIVACY ACT NOTICE
 
Section 6109 of the Internal Revenue Code requires you to give your correct TIN
to persons who must file information returns with the IRS to report interest,
dividends, and certain other income paid to you, mortgage interest you paid, the
acquisition or abandonment of secured property, cancellation of debt, or
contributions you made to an IRA. The IRS uses the numbers for identification
purposes and to help verify the accuracy of your tax return. The IRS may also
provide this information to the Department of Justice for civil and criminal
litigation and to cities, states, and the District of Columbia to carry out
their tax laws.
 
You must provide your TIN whether or not you are required to file a tax return.
Payers must generally withhold 31% of taxable interest, dividend, and certain
other payments to a payee who does not give a TIN to a payer. Certain penalties
may also apply.

INDEMNIFICATION OF DIRECTORS AND OFFICERS
    
 
   
     As authorized by Section 1701.13(E) of the Ohio Revised Code, Section 33 of
the Company's Code of Regulations ("Section 33") provides that directors and
officers of the Company may, under certain circumstances, be indemnified against
expenses (including attorneys' fees) and from other liabilities actually and
reasonably incurred by them as a result of any suit brought against them in
their capacity as a director or officer, if they acted in good faith and in a
manner they reasonably believed to be in or not opposed to the best interests of
the corporation, and, with respect to any criminal action or proceeding, if they
had no reasonable cause to believe their conduct was unlawful. Section 33 also
provides that directors and officers may also be indemnified against expenses
(including attorneys' fees) incurred by them in connection with a derivative
suit if they acted in good faith and in a manner they reasonably believed to be
in or not opposed to the best interests of the corporation, except that no
indemnification may be made without court approval if such person was adjudged
liable to the corporation.
    
 
   
     The Company has purchased director and officer liability insurance in the
amount of $5 million covering its current executive officers and directors.
    
 
   
RECENT SALES OF UNREGISTERED SECURITIES
    
 
   
     In October 1997, the Company sold 50,000 Common Shares at an adjusted price
of $20.00 per share to various individuals and companies, including some
directors, totaling $1,000,000, in an offering exempt from registration under
Rule 504 of Regulation D and Section 3(b) of the Securities Act. No underwriters
were involved in the sale and no underwriting discounts or commissions were
paid.
    
 
   
     During 1997 the Bank issued $3,700,000 of Subordinated Notes to the Company
in 3 separate offerings exempt from registration under Rule 506 of Regulation D
and Section 4(2) of the Securities Act. No underwriters were involved in the
sale and no underwriting discounts on commissions were paid.

     The financial statement schedules listed below follow:
    
 
   
                                  UNDERTAKINGS
    
 
   
     1. The undersigned Registrant hereby undertakes to file, during any period
in which offers or sales are being made, a post-effective amendment to this
registration statement:
    
 
   
          (a) To include any prospectus required by Section 10(a)(3) of the
     Securities Act of 1933;
    
 
   
          (b) To reflect in the prospectus any facts or events arising after the
     effective date of the registration statement (or the most recent
     post-effective amendment thereof) which, individually or in the aggregate,
     represent a fundamental change in the information set forth in the
     registration statement. Notwithstanding the foregoing, any increase or
     decrease in volume of securities offered (if the total dollar value of
     securities offered would not exceed that which was registered) and any
     deviation from the low or high end of the estimated maximum offering range
     may be reflected in the form of prospectus filed with the Commission
     pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
     price represent no more than a 20% change in the maximum aggregate offering
     price set forth in the "Calculation of Registration Fee" table in the
     effective registration statement; and,
    
 
   
          (c) To include any material information with respect to the plan of
     distribution not previously disclosed in the registration statement or any
     material change to such information in the registration statement.
    
 
   
     2. The undersigned Registrant hereby undertakes that, for the purpose of
determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.
    
 
   
     3. The undersigned Registrant hereby undertakes to remove from registration
by means of a post-effective amendment any of the securities being registered
which remain unsold at the termination of the offering.
    
 
   
     4. Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.
    
 
   
     5. The undersigned Registrant hereby undertakes that:
    
 
   
          (a) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or
     (4) or Rule 497(h) under the Securities Act shall be deemed to be part of
     this registration statement as of the time it was declared effective.
    
 
   
          (b) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

                                ESCROW AGREEMENT
                                ----------------


         ESCROW AGREEMENT, dated this _____ day of __________, 1999, by and
between CNBC BANCORP, an Ohio corporation ("CNBC"), and THE DELAWARE COUNTY BANK
AND TRUST COMPANY (the "Escrow Agent").

                                   WITNESSETH:
                                   -----------

         WHEREAS, CNBC proposes to offer a maximum of 125,000 shares of its no
par value common stock for sale and issuance to investors at a price of $30.00
per share to be sold in minimum lots of 100 shares as set forth in the terms of
the common stock subscription agreement dated the _____ day of __________, 1999
(the "Offering"); and

         WHEREAS, until the Offering is completed or terminated, CNBC desires to
place all proceeds from the sale of such shares in escrow with Escrow Agent;

         NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants hereinafter set forth, the parties hereto agree as follows:

         1. CNBC hereby appoints The Delaware County Bank and Trust Company as
Escrow Agent to hold certain funds deposited on behalf of CNBC with the Escrow
Agent in escrow pursuant to the terms of this Agreement.

         2. Escrow Agent shall establish an interest-bearing account or a money
market account with Federated Investors through its trust department entitled
CNBC Bancorp, Escrow Account. CNBC has reviewed the Federated Investors money
market fund and the prospectus relating thereto and certifies that it is a
permissible investment under the appropriate SEC rules. Interest will be paid on
the escrow funds based on the average monthly interest paid to the Escrow Agent
by Federated Investors. Interest will be computed from the time the escrow funds
are placed in escrow until said funds are disbursed pursuant to this Agreement.

         3. CNBC shall deliver all monies received for the payment of shares
purchased in connection with the Offering to the Escrow Agent for deposit into
the Escrow Account, together with a written account of each sale, which account
shall set forth the purchaser's name, address and social security number, the
number of shares purchased, the amount paid for such shares, and whether the
consideration received was in the form of a check, draft or money order. CNBC
shall instruct purchasers to make checks for the shares purchased payable to the
order of the Escrow Agent. Any checks received which are made payable to any
party other than the Escrow Agent shall be returned to the purchaser who
submitted the check and not accepted.

         4. The escrow period shall begin with the commencement of the Offering
and shall terminate upon the earlier to occur of the following dates:
<PAGE>   2

                  (a) A date ninety (90) days from the date the Offering
initially commences, said date to be the _____ day of __________, 1999;

                  (b) A date thirty (30) days from the original ninety-day
period, if extended by CNBC at its discretion, i.e., one hundred twenty (120)
days from the date the Offering initially commences; or

                  (c) A date prior to either of the above dates if elected by
CNBC to terminate said Offering.

During the escrow period, CNBC is aware and understands that it is not entitled
to any funds received into escrow and no amounts deposited into the Escrow
Account shall become the property of CNBC, or any other entity, or be subject to
the debts of CNBC.

         5. At the close of the Offering period, whether that be 90 days after
the initial Offering commences, 120 days after the initial Offering commences,
or upon early termination by CNBC, whichever occurs first, Escrow Agent shall
deliver to CNBC those funds in the Escrow Account relating to applications
accepted by CNBC. Escrow Agent shall refund to each subscriber, together with
interest upon said amount, all funds rejected by CNBC. The acceptance or
rejection of subscribers' funds shall be made solely by CNBC, and Escrow Agent
shall act in accordance with the instructions of CNBC with regard to the
disbursement of said funds. Only in the event the entire Offering is terminated
shall all funds be refunded to subscribers.

         6. The Escrow Agent is hereby authorized to forward each check for
collection and, upon collection of the proceeds of each check, deposit the
collected proceeds into the Escrow Account. As an alternative, the Escrow Agent
may telephone the bank on which the check is drawn to confirm that the check has
been paid.

         Any check returned unpaid to the Escrow Agent shall be returned to the
purchaser that submitted the check. In such case, the Escrow Agent shall
promptly notify CNBC of such return.

         If CNBC rejects any purchase by a purchaser for which the Escrow Agent
has already collected funds, the Escrow Agent shall promptly issue a refund
check to the rejected purchaser. If CNBC rejects any purchase by a purchaser for
which the Escrow Agent has not yet collected funds but has submitted the
purchaser's check for collection, the Escrow Agent shall promptly remit the
purchaser's check directly to the purchaser. The Escrow Agent's obligations
under this Section 6 to return funds and/or checks to purchasers shall not
commence until the Escrow Agent has received proper instructions and the
necessary information from CNBC.

         7. For its services hereunder, the Escrow Agent shall receive a fee
from CNBC of _____________________________ Dollars ($__________) payable upon
execution of this Agreement and the balance to be payable at the termination of
the Offering, plus all out-of-pocket expenses for postage and preparation of
1099s.

         8.       The Escrow Agent shall not:

                  (a) Incur any liability whatsoever except for willful
misconduct or gross negligence so long as the Escrow Agent shall have acted in
good faith; or

                  (b) Have any obligation in respect of the escrow funds, other

instituted against it in respect of this Agreement unless indemnified to the
satisfaction of the Escrow Agent against the costs and expenses of such defense,
including reasonable fees of legal counsel; or

                  (d) Be required to institute legal proceedings of any kind. In
the event that any legal action is instituted against the Escrow Agent in its
capacity as Escrow Agent, the Escrow Agent may interplead CNBC in such action
and may deposit with the Court in which such action is pending the escrow funds
which are the subject of such action, and, in such event, the Escrow Agent shall
thereupon be relieved of and discharged from any and all obligations and
liabilities under and pursuant to this Agreement in respect to such funds so
deposited with said Court; or

                  (e) Be required to be familiar with the provisions of any
other instruments or agreement shall as offering circulars or subscription
agreements, and shall not be responsible for any representations, warranties or
covenants in any other instruments or agreements.
