Item 1.01 Entry into a Material Definitive Agreement

On December 29, 2005, the Compensation Committee of the Board of Directors of
Peoples Bancorp Inc. ("Peoples") approved the acceleration of the vesting
schedule with regard to all unvested stock options previously granted to
employees of Peoples and its subsidiaries, including executive officers of
Peoples, and subsidiary directors pursuant to Peoples' various stock option
plans. Except for the acceleration of vesting, these options will continue to be
governed by their original terms and conditions. As a result of the vesting
acceleration, options to purchase an aggregate of 161,514 common shares of
Peoples became exercisable as of December 29, 2005. Vesting of these options was
to occur over the next six years, with the majority previously scheduled to vest
in 2006. No unvested options held by the directors of Peoples were accelerated,
and such options will vest based on their original vesting schedule in
accordance with the applicable stock option plan. Included in the options for
which the vesting was accelerated were options held by the following executive
officers of Peoples:

                                                       Aggregate Number
                                                          of Options
          Officer                                         Accelerated
          -------                                         -----------
          David B. Baker (a)                                 6,711
          Mark F. Bradley                                    7,526
          John W. Conlon                                     8,227
          Larry E. Holdren                                   8,206
          Carol A. Schneeberger                              8,017
          David T. Wesel (a)                                 2,425
          Joseph S. Yazombek                                 8,847

          (a) As previously reported, effective January 1, 2006, David B. Baker
          no longer serves as an executive officer of Peoples and David T. Wesel
          became an executive officer of Peoples.

Since Peoples currently accounts for its stock options in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees", Peoples will record a one-time, non-cash compensation expense of
approximately $122,000, or less than a penny per diluted share after-tax, in the
fourth quarter of 2005 due to the acceleration of these stock options. On
January 1, 2006, Peoples will adopt Statement of Financial Accounting Standards
No. 123, "Share-Based Payment" ("SFAS 123(R)") and will begin recording the cost
of stock options in the consolidated financial statements based on their fair
value. While the impact of adopting Statement 123(R) on Peoples' financial
statements will depend on the method of adoption, the level of stock-based
compensation awards and the valuation method selected by management, the
acceleration of these unvested options is expected to reduce the amount of
compensation expense that otherwise would have been recorded by Peoples in
future periods under SFAS 123(R).
