To the Plan Administrative Committee
Peoples Bancorp Inc. Retirement Savings Plan
Marietta, Ohio

                          INDEPENDENT AUDITORS' REPORT

We have audited the accompanying statements of net assets available for benefits
of Peoples Bancorp, Inc. Retirement Savings Plan as of December 31, 2002 and
2001, and the related statements of changes in net assets available for benefits
for the years 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 audit.

We conducted our audit in accordance with U. S. 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 from
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 audit provides a reasonable basis for our
opinion.

In our opinion, the December 31, 2002 and 2001 financial statements referred to
above present fairly, in all material respects, the net assets available for
benefits with fund information of Peoples Bancorp Inc. Retirement Savings Plan
as of December 31, 2002 and 2001, and the changes in net assets available for
benefits with fund information for the years then ended in conformity with U.S.
generally accepted accounting principles.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental information included in
Schedule H - Assets Held for Investment Purposes at End of Year referred to as
"Supplemental Information" is presented for the purpose of additional analysis
and is not a required part of the basic financial statements but is
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 information is the responsibility of the
Plan's management. The supplemental information has been subjected to the
auditing procedures applied in the audits of the basic financial statements and,
in our opinion, is fairly stated in all material respects in relation to the
basic financial statements taken as a whole.

                          NOTES TO FINANCIAL STATEMENTS

NOTE 1:  DESCRIPTION OF PLAN

                  The following brief description of Peoples Bancorp Inc.
                  Retirement Savings 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 substantially
                  all employees of Peoples Bancorp Inc. (the "Employer"). The
                  Plan is a qualified trust under Sections 401(a) and 401(k) of
                  the Internal Revenue Code. The Plan is subject to the
                  provisions of the Employee Retirement Income Security Act of
                  1974 ("ERISA"). The directed Trustee of the Plan is AMVESCAP
                  National Trust Company ("AMVESCAP"). The Administrator of the
                  Plan is the Retirement Planning Committee of Peoples Bank,
                  National Association ("Peoples Bank"), a subsidiary of Peoples
                  Bancorp Inc.


                  Eligibility
                  -----------

                  Employees are eligible to participate in the Plan upon
                  reaching age 21 and with one hour of service. The employee
                  completes the service requirement on his/her employment
                  commencement date. Employees may join the Plan at any time by
                  completing the election form on a day to day basis beginning
                  January 1, 2002.

                  Contributions
                  -------------


                  Each year, participants may contribute a percentage of pretax
                  annual compensation not to exceed a dollar limit which is set
                  by law. Participants may also directly rollover amounts
                  representing distributions from other qualified plans. In
                  addition, Peoples Bancorp Inc. will make a matching
                  contribution on the employee's behalf. The amount of this
                  matching contribution will be determined each year by the
                  Employer's Board of Directors. Effective for 2002 and 2001,
                  the Employer's matching contribution was 100% of the
                  employee's contribution up to the first 3% of the employee's
                  compensation and 50% of the employee's contribution on the
                  next 2% of the employee's compensation.


                  Participant Directed Investments
                  --------------------------------


                  Participants direct the investment of their contributions and
                  their allocated share of the matching contributions into
                  various investment options offered by the Plan. From the
                  period of January to October of 2002 the Plan was administered
                  by First Merchantile Trust. The Plan currently offers twelve
                  funds as investment options for participants through the
                  Plan's administered trust fund with AMVESCAP.

                  Participants may change their investment options at any time
                  via the internet.

NOTE 1:  DESCRIPTION OF PLAN (Continued)

                  Participant Accounts
                  --------------------

                  Each participant's account is credited with the participant's
                  contribution and allocations of the Employer's matching
                  contribution and Plan earnings. Allocations are based on
                  participants' 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 are immediately fully vested in their voluntary
                  contributions, the Employer's matching contributions and
                  actual earnings thereon.

                  Participant Loans Receivable
                  ----------------------------

                  Participants may apply for a loan from their account under the
                  Plan. Certain legal restrictions impose limits on the amount
                  of the loan and repayment terms. The maximum loan amount is
                  $50,000. The specific limit for any participant is 50% of
                  their account balance. If a participant has an existing loan
                  at the time of application, the $50,000 limit is reduced by
                  the highest outstanding balance of the participant's loan over
                  the previous twelve-month period or the total of all
                  outstanding loans the day the new loan is granted. Generally,
                  the participant's loan must be repaid within five years,
                  unless the proceeds are used to purchase a principal
                  residence.

                  Payment of Benefits
                  -------------------

                  The participant's benefit will equal the sum of the salary
                  deferral, the voluntary nondeductible contribution, the
                  rollover contribution and the Employer's matching contribution
                  plus net income and net losses resulting from the investment
                  of these amounts as valued on the valuation date as defined.
                  Payment of such amounts upon termination of employment may be
                  deferred until the participant reaches normal retirement,
                  becomes eligible for early retirement benefits, terminates
                  employment prior to retirement, becomes disabled or dies. If
                  the benefit is $5,000 or less, the benefit will be paid in a
                  lump-sum payment. If the benefit exceeds $5,000, the
                  participant may elect to have benefits paid in a lump-sum
                  payment or in equal installments over a fixed period of time
                  not to exceed ten years.

                  If a participant dies without a surviving spouse, either
                  before or after retirement, but before a complete distribution
                  of their accounts, then the full value of the participant's
                  accounts will be paid to a designated beneficiary. If a
                  participant dies with a surviving spouse, either before or
                  after retirement, but before a complete distribution of their
                  accounts, then the full value of the participant's accounts
                  will be paid to the surviving spouse.

NOTE 2:  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                  Basis of Accounting
                  -------------------

                  The financial statements of the Plan are prepared using the
                  accrual method of accounting.

                  Estimates
                  ---------

                  The preparation of financial statements in conformity with
                  generally accepted accounting principles requires the Plan
                  administrator to make estimates and assumptions that affect
                  certain reported amounts and disclosures. Accordingly, actual
                  results could differ from those estimates.

                  Investment Valuation and Income Recognition
                  -------------------------------------------

                  Shares of the common/collective trusts are valued at the
                  Plan's proportionate share of net shares of the fund as of the
                  most recent valuation date.

                  Shares of the registered investment companies are revalued at
                  quoted market prices which represent the net asset value of
                  shares held by the Plan at year end.

                  Investments in Peoples Bancorp Inc. common stock are carried
                  at quoted market prices.


                  The investment in Peoples Bank certificates of deposit, money
                  market funds, and the participant loans are recorded at cost
                  which approximates fair market value.


                  Dividends and interest received from investments are recorded
                  as earned on an accrual basis.

                  The Plan presents in the Statement of Changes in Net Assets
                  Available for Benefits the net appreciation (depreciation) in
                  the fair value of its investments which consists of the
                  realized gains or losses and the unrealized appreciation
                  (depreciation) on those investments.

                  Payment of Benefits
                  -------------------

                  Benefits are recorded when paid.

NOTE 4:  RELATED PARTY TRANSACTIONS


                  Certain Plan investments such as certificates of deposit and
                  shares in the common/collective trusts were managed by Peoples
                  Bank for the first few days of the this plan year. Peoples
                  Bank was also the trustee as defined by the Plan for the first
                  few days of this plan year and, therefore, these transactions
                  qualify as party-in-interest.

NOTE 5:  PAYMENT OF EXPENSES


                  The Employer elected to pay certain administrative expenses
                  and investment costs of the Plan. Should the Employer elect
                  not to pay all or part of such expenses, the Trustee then pays
                  these expenses from the Plan.



NOTE 6:  PLAN TERMINATION

                  Although it has not expressed any intent to do so, Peoples
                  Bancorp Inc. has the right under the Plan to discontinue its
                  contributions at any time and to terminate the Plan subject to
                  the provisions of ERISA. In the event of Plan termination,
                  participants will continue to be 100% vested in their
                  accounts.

NOTE 7:  TAX STATUS


                  The Employer has adopted a qualified retirement plan by
                  executing a prototype nonstandardized adoption agreement. The
                  prototype plan has received an opinion letter from the
                  national office of the Internal Revenue Service indicating
                  that the form of the plan document and adoption agreement is
                  acceptable under the Internal Revenue Code for use by
                  employers for the benefit of their employees. The Employer
                  will apply for a determination letter from the Director of
                  Rulings and Agreements of the Internal Revenue Service, and
                  expects to receive a favorable determination letter indicating
                  that the form of the Plan is in compliance with the applicable
                  requirements of Section 401(a) of the Internal Revenue Code
                  and that the Plan's trust is in compliance with the applicable
                  retirements of Section 501(a) of the Internal Revenue Code. As
                  a result, the Sponsor believes that employer contributions to
                  the trust are deductible under Section 404(a) of the Internal
                  Revenue Code, and earning on the trust are tax exempt from
                  Federal Income taxes under Section 501(a) of the Internal
                  Revenue Code until distributed.
