               PEOPLES BANCORP INC. REPORTS FIRST QUARTER EARNINGS
      ---------------------------------------------------------------------

         MARIETTA, Ohio - Peoples Bancorp Inc. (NASDAQ: PEBO) announced net
income of $5,366,000 for the first quarter of 2004, up 7% from $5,014,000 a year
ago. Earnings per diluted shares were $0.50 for the three months ended March 31,
2004, compared to $0.49 earned in last year's first quarter. Peoples' increased
first quarter earnings were attributable to higher levels of net interest income
and non-interest revenues, primarily the result of the Kentucky Bancshares
Incorporated ("KBI") acquisition completed in mid-2003 and balance sheet
restructuring initiatives in late 2003.
         "Completing the first quarter with a 7% net income growth over the same
quarter last year is a good start for the year," said Robert E. Evans, Chairman,
President and CEO. "We are confident that recent strategic actions provide us
with a solid foundation for long-term earnings growth."
         Evans added, "We continue the drive to expand our financial and
insurance customer base through selective business acquisitions, like the
recently announced addition of the Putnam Agency in the Ashland, Kentucky and
Huntington, West Virginia markets. The Putnam Agency has been developing
relationships since 1904."
         Through the first three months of 2004, net interest income totaled
$13,548,000 compared to $13,058,000 in 2003's first quarter. This increase was
due to earning assets added through the KBI acquisition, as well as Peoples'
efforts to reduce cost of funds more than the corresponding decline in yields
from assets repricing downward in the current rate environment. For the quarter
ended March 31, 2004, Peoples' average cost of funds was 2.28% compared to 3.03%
for the same quarter a year ago, while the average yield on earning assets was
5.60% and 6.41% for the same periods, respectively. Although these factors have
produced additional net interest income, they have also contributed to
compression of net interest margin from a year ago. In the first quarter of
2004, net interest margin was 3.56% versus 3.70% for the same quarter in 2003
and 3.32% for the fourth quarter of 2003. The net interest margin for fourth
quarter of 2003 was also impacted by $376,000 of combined additional premium
amortization and reduction in interest income on mortgage-backed securities.
Excluding these adjustments, the fourth quarter net interest margin would have
been 3.41%.
         "The Federal Reserve's decision to leave rates at such low levels for
an unprecedented period continues to impact Peoples' net interest income and
margin," said Jack Conlon, Peoples' Chief Financial Officer. "However, a modest
increase in earning assets, due to acquisitions and an investment growth
strategy, plus the balance sheet restructuring in late 2003, mitigated some of
the impact of declining asset yields. Since net interest income remains a key
component of our earnings, we continue to manage Peoples' interest rate risk
position for the inevitable increase in market rates, while attempting to make
the best of current conditions."
         Non-interest income was $4,825,000 for the first quarter of 2004, up
23% from $3,935,000 a year ago. Revenues from offices added in the KBI
acquisition, primarily deposit account service charges and fiduciary income, and
additional business owned life insurance ("BOLI") were the main factors
contributing to the overall increase in non-interest income.
         "Our disciplined acquisition and expansion strategy over the last
several years has afforded us the ability to grow both traditional and
non-traditional revenues," commented Mark Bradley, Peoples' Chief Operating
Officer. "In addition, we believe non-traditional revenues, such as insurance
and investment commissions and fiduciary revenues, remain viable sources for
future non-interest income growth. With earnings pressures from net interest
margin compression likely to linger, we continue to focus our efforts on further
diversifying revenues and reducing Peoples' reliance on net interest income."
         Deposit account service charges totaled $2,253,000 for the first
quarter of 2004, a 31% increase compared to the same period in 2003. This
increase was primarily the result of a combination of higher volumes of
overdraft and non-sufficient funds fees and an overall increase in the number of
checking accounts from the KBI acquisition, as well as an increase in the per
item amount of certain cost recovery fees. Peoples' fiduciary revenues improved
to $774,000 in the first quarter, from $586,000 for the same period in 2003,
attributable to additional assets under management. E-banking revenues,
primarily ATM and debit card fees, grew 15% from a year ago, totaling $523,000
for the first quarter of 2004. Peoples' mortgage banking activities produced
revenues of $199,000 for the three months ended March 31, 2004, versus $230,000
for 2003's first quarter, reflecting lower levels of real estate loan refinance
activity.
         Non-interest expense was $10,290,000 in the first quarter of 2004
versus $9,119,000 for the same period in 2003. Salaries and benefits, Peoples'
largest expense, totaled $5,389,000 for the quarter ended March 31, 2004, an
increase of 14% from a year ago, due mostly to annual salary adjustments
necessary to retain and recruit key associates and the addition of approximately
30 associates in conjunction with the KBI acquisition. For the first quarter of
2004, occupancy and equipment costs increased 11%, as acquisitions and
investments in technology produced additional depreciation expense in 2004,
while intangible amortization doubled from a year ago due to the KBI
acquisition. Compared to the fourth quarter of 2003, non-interest expense was
down $7,039,000 in the first quarter of 2004, with long-term debt prepayment
penalties which occurred in the fourth quarter of 2003 accounting for $6,817,000
of the decline. Excluding the prepayment penalties and intangible amortization,
non-interest expense decreased 2% due to a reduction in various operating
expenses.
         The non-interest leverage ratio serves as a measurement of efficiency
and performance and is a key performance indicator for Peoples. The ratio,
defined as non-interest income as a percentage of operating expenses, excludes
gains and losses on securities transactions and asset disposals, as well as
intangible asset amortization. For the three months ended March 31, 2004, the
non-interest leverage ratio was 46.7%, an improvement from 44.1% a year ago.
         "The improvement in the non-interest leverage ratio is a reflection of
our commitment to grow non-interest revenues without proportional increases in
operating expense," commented Bradley. "We continue to analyze opportunities to
enhance revenues and limit expenses, as we work towards our strategic goal of a
non-interest leverage ratio in excess of 50%."
         In the first quarter of 2004, Peoples' tax advantaged investments
produced additional benefits, which reduced Peoples' effective tax rate to 27.0%
compared to 28.8% a year ago. The lower effective tax rate also accounted for a
portion of Peoples' first quarter earnings growth. The tax strategies employed
are long-term and will help Peoples manage its overall tax burden in future
years.
         Nonperforming loans comprised 0.76% of total loans at March 31, 2004,
compared to 0.73% at December 31, 2003, while nonperforming assets comprised
0.43% and 0.41% of total assets for the same periods, respectively. In the first
quarter of 2004, Peoples' provision for loan losses was $794,000, down from
$915,000 in the prior quarter and down from $831,000 a year ago. At March 31,
2004, the allowance for loan losses was $14.8 million, or 1.62% of total loans,
compared to $14.6 million, or 1.59% of total loans, at year-end 2003.
          "Our long-standing commitment to sound underwriting standards, coupled
with a diligent loan review process, have produced good quality loans," stated
Bradley. "In addition, our loan delinquencies have decreased modestly, and we
have maintained solid asset quality ratios that compare favorably to our peers."
         In the first quarter of 2004, net loan chargeoffs were $595,000, up
from $554,000 a year ago but down from $763,000 in the fourth quarter of 2003.
Consumer loans comprised the largest portion of net chargeoffs, totaling
$275,000 and $201,000 for the three months ended March 31, 2004 and 2003,
respectively. Net chargeoffs relating to the Overdraft Privilege Program were
$135,000 in the first quarter of 2004 versus $117,000 in 2003's first quarter.
Real estate net chargeoffs totaled $155,000 for the first three months of 2004,
up from $7,000 for the same period in 2003. In the first quarter of 2004,
Peoples' commercial loan recoveries exceeded chargeoffs, resulting in net
recoveries of $100,000 compared to net chargeoffs of $186,000 in 2003's first
quarter. A significant portion of the commercial loan recoveries relate to a
group of loans, in a single customer relationship, which had been charged-down
in the first half of 2002.
         At March 31, 2004, loans totaled $910.8 million, down $4.2 million
since year-end 2003, due to declines in real estate and consumer loans. Peoples
also had $2.2 million of fixed-rate real estate loans originated and held for
sale into the secondary market. Peoples is also servicing $85 million of
fixed-rate real estate loans previously sold into the secondary markets due to
the associated interest rate risk.
         In late 2003, Peoples entered into an agreement to sell its existing
credit card portfolio and formed an affiliation with an unrelated financial
institution to serve the credit card needs of Peoples' customers. Final
settlement of the sale, which did not materially impact Peoples' results of
operation or financial position, occurred in the first quarter of 2004.
          "Our first quarter results reflect the challenge of growing earnings
with interest rates remaining at extremely low levels," summarized Bradley. "We
remain committed to a needs-based approach that fulfills the financial needs of
our customers as a means of enhancing Peoples' profitability. Our long-term
objectives are best achieved in more normal economic and interest rate
conditions."
