                      (a)  The annual meeting of shareholders of Croghan
                           Bancshares, Inc. was held on May 11, 1999.
                      (b)  Proxies were solicited pursuant to Regulation 14A
                           of the Securities Exchange Act of 1934.  There was
                           no solicitation in opposition to management's
                           nominees for Directors and all nominees were

                           holder proposal resolved, the Directors of Croghan
                           Bancshares, Inc. should attempt to maximize share-
                           holder value by contemplating a tax-free merger with
                           a larger bank rather than continuing the present
                           course of management of the bank. The results of the
                           matters presented were as follows:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The information presented may contain forward-looking statements regarding
future financial performance which are not historical facts and involve various
risks and uncertainties. Actual results and performance could materially differ
from those contemplated in such forward-looking statements.

PERFORMANCE SUMMARY

Assets at June 30, 1999 totalled $345,140,000 compared to $350,144,000 at 1998
year end. Total deposits decreased to $289,869,000 from $301,456,000 at year end
and total loans receivable decreased to $233,067,000 from $239,359,000 at year
end.

Net income for the quarter ended June 30, 1999 was $785,000 or $.41 per common
share compared to $797,000 or $.42 per common share for the same period in 1998,
and net income for the six-month period ended June 30, 1999 was $1,481,000 or
$.78 per common share compared to $1,524,000 or $.80 per common share for the
same period in 1998. Operating results for 1999 were adversely impacted by an
increase in the salaries, wages amd employee benefits expense. The increase is
largely a result of above normal medical claims incurred within the first six
months of 1999.

DEPOSITS, LOANS RECEIVABLE, INVESTMENT SECURITIES, AND STOCKHOLDERS' EQUITY

Total deposits at June 30, 1999 decreased $11,587,000 or 3.8 percent from 1998
year end. The liquid deposit category (demand, savings, NOW and money market
deposit accounts) decreased $4,139,000 while the time deposit category decreased
$7,448,000. Total loans receivable decreased $6,292,000 or 2.6 percent from 1998
year end. Total investment securities increased $7,151,000 or 9.4 percent from
1998 year end.

Stockholders' equity at June 30, 1999 increased to $34,209,000 or $17.94 book
value per common share compared to $33,705,000 or $17.70 book value per common
share at December 31, 1998. The balance in stockholders' equity at June 30, 1999
included a net unrealized holding loss on securities classified as
available-for-sale of $222,000 (net of deferred income taxes totalling
$114,000). At December 31, 1998, stockholders' equity included a net unrealized
holding gain on securities classified as available-for-sale of $174,000 (net of
deferred income taxes totalling $90,000). Consistent with the Corporation's
quarterly dividend policy, a dividend of $.18 per share was declared on June 15,
1999 to be distributed on July 30, 1999.

NET INTEREST INCOME

Net interest income, which represents the excess revenue generated from earning
assets over the interest cost of funding those assets, increased $16,000 for the
quarter ended June 30, 1999 compared to the same period in 1998, and increased
$27,000 for the six-month period ended June 30, 1999 compared to the same period
in 1998. The net interest yield (net interest income divided by average earning
assets) was 4.37 percent for the quarter ended June 30, 1999 compared to 4.43
percent for the same period in 1998, and was 4.30 percent for the six-month
period ended June 30, 1999 compared to 4.39 percent for the same period in 1998.

</TABLE>

The provision for loan losses for the first six months of 1999 appearing in the
Consolidated Statements of Operations and Comprehensive Income totalled
$120,000. This provision compares to $120,000 expensed during the same period in
1998. Net loan charge offs were $201,000 for the first six months of 1999
compared to net charge offs of $82,000 during the same period in 1998.

Nonaccrual loans totalled $566,000 at June 30, 1999 compared to $315,000 at
December 31, 1998. Loans past due 90 days or more at June 30, 1999 increased by
$440,000 and other potential problem loans increased $265,000 from December 31,
1998 figures. The asset quality trends are being monitored throughout 1999 to
ensure adequate provisions for loan losses are calculated and expensed. The
Corporation's allowance for loan losses as a percentage of outstanding loans
remained steady at 1.43 percent for June 30, 1999 and December 31, 1998.

It is the Corporation's policy to maintain the allowance for loan losses at a
level to provide for reasonably foreseeable losses. To accomplish this
objective, a loan review process is conducted by an outside consulting firm
which facilitates the early identification of problem loans and ensures sound
credit decisions. Management considers the balance at June 30, 1999 to be
adequate to provide for losses inherent to the loan portfolio.

NON-INTEREST INCOME

Total non-interest income increased $47,000 or 11.0 percent for the quarter
ended June 30, 1999 compared to the same period in 1998, and increased $46,000
or 5.4 percent for the six-month period ended June 30, 1999 compared to the same
period in 1998. Trust department fee income increased $15,000 between comparable
quarterly periods and $37,000 between comparable six-month periods. Service
charges on deposit accounts increased $6,000 between comparable quarterly
periods and increased $20,000 between comparable six-month periods.

Gains on the sale of loans to the Federal Home Loan Mortgage Corporation
(Freddie Mac) totalled $3,000 for the quarterly period ended June 30, 1999
compared to $20,000 for the quarterly period ending June 30, 1998, and $4,000
for the first six months of 1999 compared to $32,000 for the first six months of
1998. Other operating income increased $43,000 between comparable quarterly
periods and increased $17,000 between comparable six-month periods.

NON-INTEREST EXPENSES

Total non-interest expenses increased $113,000 or 4.3 percent for the quarter
ended June 30, 1999 compared to the same period in 1998, and increased $173,000
or 3.3 percent for the six-month period ended June 30, 1999 compared to the same
period in 1998. Salaries, wages and employee benefits increased $91,000 between
comparable quarterly periods and $157,000 between comparable six-month periods.
Net occupancy expense of premises decreased $4,000 between comparable quarterly
periods and $1,000 between comparable six-month periods. Goodwill amortization

Bancshares Corp. was unchanged for the comparable quarterly and six-month
periods while other operating expenses increased $26,000 or 3.0 percent between
quarterly periods and increased $17,000 or 1.0 percent between comparable six-
month periods.



FEDERAL INCOME TAX EXPENSE

Federal income tax expense decreased $38,000 or 9.1 percent between comparable
quarterly periods, and $57,000 or 7.1 percent between comparable six-month
periods due to lower income before federal income taxes. The Corporation's
effective tax rate for the six months ended June 30, 1999 decreased to 33.5
percent compared to 34.5 percent for the same period in 1998.

LIQUIDITY AND CAPITAL RESOURCES

Average federal funds sold positions of $1,519,000 and $3,540,000 were
maintained for the quarterly and six-month periods, respectively, ended June 30,
1999. Short-term borrowings of federal funds purchased and repurchase agreements
averaged $6,086,000 and $5,314,000 for the quarterly and six-month periods,
respectively.

Federal Home Loan Bank borrowings totalled $7,000,000 at June 30, 1999. Of that
amount, $5,000,000 is due in July 1999 and $2,000,000 is due in October 2005.

Capital expenditures for premises and equipment totalled $109,000 for the six-
month period ended June 30, 1999. This compares to $376,000 for same period in
1998. Projected 1999 capital expenditures total $290,000.

YEAR 2000 PREPAREDNESS

There is considerable concern over the ability of many computer software
programs to function when the year 2000 arrives. This concern arises because
many existing programs use only the last two digits to refer to the year. As
such, programs do not recognize the difference between a year that begins with
"20" instead of the current "19".

Computer operations are a crucial part of The Croghan Colonial Bank's (Croghan)
operating strategy and a comprehensive program has been implemented to verify
that all internal software will operate properly. Certified Year 2000 compliant
mainframe computer hardware and software was purchased and installed in 1997. To
ensure the validity of this certification, multiple testing sessions were
conducted during the fourth quarter of 1998. Additional testing occurred during
the first quarter of 1999 and sucessfully involved changing the processing dates
to December 31, 1999 and January 1, 2000.

A testing program has also been implemented to verify that all desktop personal
computers and network servers will function properly in the year 2000. Year 2000
test software and date changing procedures have been effected on all of the
personal computers located throughout the organization. The network servers were
tested during the first quarter of 1999 and sucessfully handled the date change.

Croghan's direct exposure to embedded microchip technology is of little or no
consequence. Unlike many manufacturers which use computerized robots,
controllers, and assembly lines, Croghan has only to assess its elevators and
HVAC systems. All such systems have been evaluated and were determined to be
free of embedded microchip technology.

Croghan also has a vested interest in the computer processing requirements of
its vendors and customers. Many primary suppliers have been contacted to ensure
their preparedness. A tickler system was instituted to follow up with those
vendors that have not replied or possibly indicated some question as to their
<PAGE>   10

commitment to readiness. These vendors will be contacted throughout 1999.

From a customer standpoint, the problem could affect the ability of Croghan's
borrowers to service debts if their direct operations, vendors, or customers
were impacted. To raise the customers' level of awareness, Croghan sponsored two
Year 2000 seminars for local businesses in 1998. In 1999 information has been
provided through customer statement stuffers containing special Year 2000
information for safety and soundness. A Year 2000 information section can be
found at the Croghan web page (www.croghan.com). Additionally, the Federal
Reserve Bank instituted a Year 2000 examination process to which Croghan is
subject. As a part of that process, Croghan was required to identify those
commercial customers (borrowers and depositors) which exceeded a set threshold
and prepare written Year 2000 assessment work sheets. As of June 30, 1999
approximately 220 such assessments have been completed. A tickler system was
then instituted to follow up on those customers with a high inclination to Year
2000 risk. The Year 2000 risk assessment for Croghan's borrowers is a factor in
determining the provision for loan losses.

A majority of the cost associated with upgrading Croghan's internal hardware and
software was incurred when the mainframe equipment was purchased in 1997.
Additional direct expenditures attributable to Year 2000 internal hardware and
software approximated $32,000 in 1998 and are estimated at $25,000 for 1999.
Costs associated with the vendor and customer compliance portions of the Year
2000 preparedness plan are difficult to quantify, but direct costs of the
program were estimated at $25,000 in 1998 and should approximate a similar
amount in 1999. The estimated year to date expenditure totalled $13,000. An even
more difficult amount to quantify is the personnel time required to verify
system integrity and assure compliance with the policies and procedures mandated
by the regulatory agencies. Such expense is estimated to have amounted to over
$100,000 since 1997 and will likely approximate $75,000 in 1999.

Croghan has a well established and tested contingency plan for mainframe and
personal computer processing. The plan has been implemented on various occasions
during times of electrical and telephone circuit interruption. A worst-case Year
2000 scenario would likely be similar in nature to interruptions that have been
experienced in the past. At those times, Croghan has reverted to the manual
processing of customer transactions at the teller windows with mainframe
processing accomplished at the off-site disaster recovery location (the off-site
location was tested in October 1998, January 1999, and March 1999 for Year 2000
preparedness and found to be satisfactory). Croghan has strived to ensure that
its contingency plan, vendor, internal processing, and customer segments of the
Year 2000 preparedness plan are being executed.
