                                   WITNESSETH:

                  WHEREAS, the Board of Directors of the COMPANY adopted the
Peoples Bancorp Inc. 1998 Stock Option Plan (the "PLAN") on December 11, 1997;
and

                  WHEREAS, the stockholders of the COMPANY, upon the
recommendation of the COMPANY's Board of Directors, approved the PLAN at the
Annual Meeting of Shareholders held on April 9, 1998; and

                  WHEREAS, pursuant to the provisions of the PLAN, the Board of
Directors of the COMPANY has appointed a Stock Option Committee (the
"COMMITTEE") to administer the PLAN and the COMMITTEE has determined that an
option to acquire common shares, without par value (the "COMMON SHARES"), of the
COMPANY should be granted to the OPTIONEE under the terms and conditions set
forth in this Agreement;

                  NOW, THEREFORE, in consideration of the premises, the parties
hereto make the following agreements, intending to be legally bound thereby:

                  1. Grant of OPTION. The COMPANY hereby grants to the OPTIONEE
an option (the "OPTION") to purchase ____________COMMON SHARES of the COMPANY.
The OPTION is intended to qualify as an incentive stock option under Section 422
of the Internal Revenue Code of 1986, as amended (the "CODE").

                  2.       Terms and Conditions of the OPTION.

                  (A) OPTION PRICE. The purchase price (the "OPTION PRICE") to
be paid by the OPTIONEE to the COMPANY upon the exercise of the OPTION shall be
$_____ per share (being 100% of the Fair Market Value (as that term is defined
in the PLAN) for the COMMON SHARES of the COMPANY on the date of this
Agreement), subject to adjustment as provided herein.

                  (B) Exercise of the OPTION. The OPTION may not be exercised
until the OPTIONEE shall
have_______________________________________________________. Thereafter, the
OPTION may be exercised as follows:

                           i)  at any time after
______________________________________ of the COMMON SHARES subject to
the OPTION;

                           ii) at any time after
______________________________________ of the COMMON SHARES subject to
the OPTION;

                           iii) at any time after
_____________________________________ of the COMMON SHARES subject to
the OPTION; and

                           iv) at any time after
_____________________________________ of the COMMON SHARES subject to
the OPTION.

                  Subject to the other provisions of this Agreement, if the
OPTION becomes exercisable as to certain COMMON SHARES, it shall remain
exercisable as to those COMMON SHARES until the date of expiration of the OPTION
term. The COMMITTEE may, but shall not be required to (unless otherwise provided
in this Agreement), accelerate the schedule of the time or times when the OPTION
may be exercised.

                  The grant of this OPTION shall not confer upon the OPTIONEE
any right to continue as an employee of the COMPANY or of any subsidiary of the
COMPANY nor limit in any way the right of the COMPANY or of any such subsidiary
to terminate the status of the OPTIONEE as an employee in accordance with law or
the COMPANY's or the subsidiary's, as appropriate, governing corporate
documents.

                  (C) OPTION Term.  The OPTION shall in no event be exercisable
                      ------------
after the expiration of ten (10) years from the date of this Agreement.

                  (D) Method of Exercise. To the extent that it is exercisable,
                      -------------------
the OPTION may be exercised by mailing or delivering to the COMMITTEE a written
notice of exercise, signed by the OPTIONEE, or in the event of the death of the
OPTIONEE, by such other person as is entitled to exercise the OPTION. The notice
of exercise shall state the number of COMMON SHARES in respect of which the
OPTION is being exercised, and shall either be accompanied by the payment of the
full OPTION PRICE of such COMMON SHARES, or shall fix a date (not more than ten
business days from the date of the notice) for the payment of the full OPTION
PRICE of the COMMON SHARES being purchased. The OPTION PRICE may be paid in
cash, or by the transfer by the OPTIONEE to the COMPANY of free and clear COMMON
SHARES already owned by the OPTIONEE having a Fair Market Value (as that term is
defined in the PLAN) on the exercise date equal to the OPTION PRICE, or by a
combination of cash and COMMON SHARES already owned by the OPTIONEE equal in the
aggregate to the OPTION PRICE for the COMMON SHARES being purchased.

                  3. Adjustments and Changes in the COMMON SHARES subject to the
                     -----------------------------------------------------------
OPTION. In the event there is any change in the COMMON SHARES resulting from
- -------
stock splits, stock dividends, combinations or exchanges of shares, or other
similar capital adjustments, the number of COMMON SHARES subject to the OPTION
and the OPTION PRICE of the optioned COMMON SHARES shall be appropriately
adjusted to reflect such change.

                  4. Vesting Acceleration of OPTIONS in an Acquisition
                     Transaction.
                     -------------------------------------------------

                  (A) In the event the COMPANY shall consolidate with, merge
into, or transfer all or substantially all of its assets (an "ACQUISITION
TRANSACTION") to another corporation or corporations (herein referred to as
"SUCCESSOR EMPLOYER CORPORATION"), then each OPTION outstanding under the PLAN
shall become exercisable in full, whether or not then exercisable by its terms,
immediately upon consummation of the ACQUISITION TRANSACTION. As a condition of
any such ACQUISITION TRANSACTION, the COMPANY shall require that the successor
employer corporation obligate itself to continue this PLAN and to assume all
obligations under the PLAN in a manner consistent with the provisions of Section
424(a) of the CODE. In the event that such successor employer corporation
terminates for any reason the employment of any OPTIONEE who is a Key Employee,
as defined by the PLAN, within the one year period immediately following the
consummation of the ACQUISITION TRANSACTION, such OPTIONEE shall have the right
to exercise his then unexercised OPTIONS during the period ending on the earlier
of the expiration of the term of the OPTIONS or three months following the date
of the OPTIONEE's termination of employment.

                  (B) The grant of the OPTION shall not affect in any way the
right of the COMPANY to consolidate with, merge into, or transfer all or
substantially all of its assets to, another corporation or corporations.

                  5. Assignability of the OPTION. The OPTION shall not be
                     ----------------------------
assignable or transferable except, in the event of the death of the OPTIONEE, by
the will of the OPTIONEE, or by the laws of descent and distribution. The OPTION
shall be exercisable, during the OPTIONEE's lifetime, only by the OPTIONEE.

                  6. Exercise After OPTIONEE Ceases to be an Employee. If an
                     -------------------------------------------------
OPTIONEE's employment with the COMPANY and its subsidiaries terminates for any
reason other than (i) death of the OPTIONEE, (ii) the disability of the OPTIONEE
within the meaning of Section 22(e)(3) of the CODE, (iii) the retirement of the
OPTIONEE under the provisions of any retirement plan of the COMPANY and its
subsidiaries, or (iv) any reason (other than for an act of fraud or intentional
misrepresentation, or embezzlement, misappropriation or conversion of assets or
opportunities of the COMPANY or any subsidiary, hereafter referred as "CAUSE")
after the OPTIONEE has been employed by the COMPANY and/or its subsidiaries for
at least 10 consecutive years prior to the OPTIONEE's termination of employment,
the portion of the OPTION which has not yet become exercisable in accordance
with Section 2(B), shall immediately terminate.
                           If the termination of employment of the OPTIONEE was
due to retirement under the provisions of any retirement plan of the COMPANY or
any subsidiary or if the termination of employment was due to a reason other
than for CAUSE and the OPTIONEE had been employed by the COMPANY and/or one or
more subsidiaries for at least 10 consecutive years prior to the OPTIONEE's
termination of employment, all of such OPTIONEE's OPTIONS may be exercised in
full, whether or not then exercisable in accordance with Section 2(B), and the
right of the OPTIONEE to exercise the OPTIONS shall terminate upon the earlier
to occur of the expiration of the term of the OPTIONS or three months after the
date of termination of employment.
                           If the termination of employment was due to the
death of an OPTIONEE who was an employee of the COMPANY and/or any subsidiary
at the time of death, such OPTIONS may be exercised in full, whether or not
then exercisable in accordance with Section 2(B), and the right of the
representative or representatives of the OPTIONEE's estate (or the person or
persons who acquire by bequest or inheritance) the right to exercise the
OPTIONEE's OPTIONS) to exercise the OPTIONS shall terminate upon the earlier
to occur of the expiration of the term of the OPTIONS or one year after the
date of death of the OPTIONEE.
                           If the termination of employment was due to the
disability of the OPTIONEE within the meaning of Section 22(e)(3) of the CODE,
such OPTIONS may be exercised in full, whether or not then exercisable in
accordance with Section 2(B), and the right of the OPTIONEE to exercise the
OPTIONS shall terminate upon the earlier to occur of the expiration of the term
of the OPTIONS or one year after the date of termination of employment.
                           If the termination of employment of the OPTIONEE was
due to reasons other than for CAUSE and the OPTIONEE had not been employed by
the COMPANY and/or one or more subsidiaries for at least 10 consecutive years
prior to the OPTIONEE's termination of employment, the OPTIONEE's OPTIONS may
be exercised only to the extent then exercisable under Section 2(B) on the date
of termination of employment, and the right of the OPTIONEE to exercise the
OPTIONS shall terminate upon the earlier to occur of the expiration of the term
of the OPTIONS or three months after the date of termination of employment.
                           If the termination of employment of the OPTIONEE was
for CAUSE, all OPTIONS which have not been exercised as of the date of
termination of employment shall terminate immediately as of the date of
termination of employment.

                  7. Restrictions on Exercise. Anything contained in this
                     -------------------------
Agreement or elsewhere to the contrary notwithstanding:

                  (A) The OPTION shall not be exercisable for the purchase of
any COMMON SHARES subject thereto except for:

                           i)   COMMON SHARES subject thereto which at the time
of such exercise and purchase are registered under the Securities Act of 1933,
as amended (the "ACT"); and

                           ii) COMMON SHARES subject thereto which at the time
of such exercise and purchase are
exempt or are the subject matter of an exempt transaction or are registered by
description, by coordination or by qualification, or at such time are the

accordance with Chapter 1707 of the Ohio Revised Code, as amended; and

issued upon the exercise thereof to a person who (at the time of such exercise
or thereafter) is an affiliate of the COMPANY for purposes of Rule 144
promulgated under the ACT, or are sold and issued in reliance upon exemptions
under the securities laws of any state, then upon such sale and issuance:

                           i)  Such COMMON SHARES shall not be transferable by
the holder thereof, and neither the COMPANY nor its transfer agent or registrar,
if any, shall be required to register or otherwise to give effect to any
transfer thereof and may prevent any such transfer, unless the COMPANY shall
have received an opinion from its counsel to the effect that any such transfer
would not violate the ACT or the applicable laws of any state; and

                           ii) The COMPANY may cause each share certificate

the COMPANY shall deem advisable to insure compliance with applicable federal
and state laws and regulations.

                  (D) Nothing contained in this Agreement or elsewhere shall be
construed to require the COMPANY to take any action whatsoever to make the
OPTION exercisable or to make transferable any COMMON SHARES purchased and
issued upon the exercise of the OPTION.

                  8. Rights of the OPTIONEE as a Shareholder. The OPTIONEE shall
