                         Report of Independent Auditors


Executive Committee of the Board of Directors
Park National Corporation

We have audited the accompanying statements of net assets available for benefits
of the Park National Corporation Employees Stock Ownership Plan (the Plan) as of
December 31, 2002 and 2001, and the related statements of changes in net assets
available for benefits for the year then ended. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the
audits 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
statements presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of the Plan at
December 31, 2002 and 2001 and the changes in its net assets available for
benefits for the year then ended, in conformity with accounting principles
generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The schedule of assets held for
investment purposes and schedule of reportable transactions are presented for
the purpose of additional analysis and are not a required part of the basic
financial statements, but are supplementary information required by the
Department of Labor's Rules and Regulations for Reporting and Disclosure under
the Employee Retirement Income Security Act of 1974. The supplemental schedules
are the responsibility of the Plan's management. The supplemental schedules have
been subjected to the auditing procedures applied in our audit of the basic
financial statements, and, in our opinion, are fairly stated in all material
respects in relation to the financial statements taken as a whole.

1. DESCRIPTION OF THE PLAN

The following description of the Park National Corporation Employees Stock
Ownership Plan (the Plan) provides only general information. Participants should
refer to the Plan agreement for a more complete description of the Plan's
provisions.


GENERAL

The Plan is a defined contribution plan covering full-time or part-time
employees of Park National Corporation and subsidiaries (Park) who have one year
of service, age twenty-one or older, and worked at least 1,000 hours. It is
subject to the provision of the Employee Retirement Income Security Act of 1974
(ERISA).


CONTRIBUTIONS

Each year, participants may contribute up to 25% of their pretax annual
compensation, as defined in the Plan. Participants may also contribute rollover
amounts representing distributions from other qualified defined contribution
plans. The maximum salary deferral permitted by the Internal Revenue Code (Code)
for 2002 and 2001 was $11,000 and $10,500.

Park provides a matching contribution at a level established annually by Park.
For 2002, Park matched 50% up to the first 15% of compensation. In 2001, up to
the first 14% of compensation, Park matched 20% of officers' contributions and
40% of non-officers' contributions in investments other than Park National
Corporation common stock. The match was 50% for officers and non-officers for
investments in Park National Corporation common stock.


PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's salary deferral
and allocation of Park's contribution and Plan earnings. Allocations are based
on participant earnings or account balances, as defined. The benefit to which a
participant is entitled is the benefit that can be provided from the
participant's account.


VESTING

Participants' accounts are 100% vested at all times.


                                                                               4




                            Park National Corporation
                         Employees Stock Ownership Plan

                    Notes to Financial Statements (continued)


1. DESCRIPTION OF THE PLAN (CONTINUED)

PAYMENTS OF BENEFITS

On termination of service and before age 59 1/2, a participant may elect to
receive either a lump sum or rollover amount equal to the value of his or her
account. After age 59 1/2, a participant may elect lump sum, rollover, or
installments over a period certain not to exceed the participant's (and his
designated beneficiary's) life expectancy.

KSOP
Effective January 1, 2002, the Plan was amended and restated to become a KSOP
Plan that invests in Park National Corporation common stock. The Plan is
unleveraged and all new contributions (both employer and employee) will be used
to purchase Park National Corporation common stock only. Participants have the
ability to diversify their investments upon reaching age 55. The Plan has
changed its name from Park National Corporation Employees Voluntary Salary
Deferral Plan and Trust to Park National Corporation Employees Stock Ownership
Plan. All other provisions of the Plan remain the same.


2. SUMMARY OF ACCOUNTING POLICIES

BASIS OF PRESENTATION

The financial statements of the Plan are prepared on the accrual basis.

VALUATION OF INVESTMENTS

Investments are stated at fair value. Park National Corporation common stock is
valued at its quoted market price. Shares of mutual funds are valued at quoted
market prices which represent the net asset value of shares held by the Plan at
year end.


                                                                               5

                         Employees Stock Ownership Plan

                    Notes to Financial Statements (continued)


2. SUMMARY OF ACCOUNTING POLICIES (CONTINUED)

ADMINISTRATIVE EXPENSES

All administrative expenses charged to the Plan are borne by Park. Trustee fees
for the Plan are waived each year. Park also provides other accounting and
administrative services to the Plan.

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires management to make estimates
and assumptions that affect reported amounts of assets and liabilities at the
date of the financial statements, and the reported amounts of investment income
and expenses during the reporting period. Actual results could differ from those
estimates.

RECLASSIFICATIONS

Certain amounts in the prior year financial statements have been reclassified to
conform with the current year presentation. These reclassifications had no
effect on net assets available for benefits as previously reported.


3. PLAN MERGER

On December 31, 2001, Security Banc Corporation 401(k) Profit Sharing Savings
Plan (the Security Plan) merged into the Plan as of December 31, 2001.
Participants previously eligible for the Security Plan were immediately eligible
to participate in the Plan. As a result of the merger, cash of $4,958,851 and
shares of Park National Corporation common stock (Ticker Symbol PRK) with a
market value of $7,674,321, totaling $12,633,172 were transferred to the Plan on
January 2, 2002 which is reflected as a receivable at December 31, 2001.


4. PLAN TERMINATION

Although Park has not expressed any intent to do so, it has the right under the
Plan to discontinue its contributions at any time and to terminate the Plan
subject to the provisions of ERISA.


                                                                               6

5. INVESTMENTS

The Plan's investments are held in trust by The Park National Bank, a wholly
owned subsidiary of Park National Corporation. The Plan's investments (including
investments bought and sold as well as held during the year) appreciated
(depreciated) in fair value during the years ended December 31, 2002 and 2001 as
follows:

6. INCOME TAX STATUS

The Plan has received a determination letter from the Internal Revenue Service
dated January 3, 1994, stating that the Plan is qualified under Section 401(a)
of the Code and, therefore, the related trust is exempt from taxation. However,
subsequent to the issuance of the favorable determination letter, the Plan has
been amended. The Plan has requested a new determination letter from the
Internal Revenue Service.


                                                                               7

compliance with the applicable requirements of the Code and, therefore, believes
that the Plan is qualified and the related trust is tax exempt.

The Plan held the following party-in-interest investments (at fair value):
