                                     PART I
 
ITEM 1.   BUSINESS
 
GENERAL
 
     Second Bancorp, Incorporated, ("Second Bancorp") is a one-bank holding
company which owns The Second National Bank of Warren ("Second National"), a
Warren, Ohio based commercial bank. Operating through thirty-three branches and
one loan production office, Second National offers a wide range of commercial
and consumer banking and trust services primarily to business and individual
customers in various communities in an eight county area in northeastern Ohio.
At December 31, 1998, Second Bancorp had consolidated total assets of $1.43
billion, deposits of $1.103 billion and shareholders' equity of $123 million.
 
     Second National focuses its marketing efforts primarily on local
independent commercial and professional firms, the individuals who are the
owners and principals of such firms as well as the low-to-moderate to upper
income retail customers in Second National's trade areas. In recent years,
Second Bancorp has emphasized increased commercial and direct consumer and real
estate lending and market area expansion. Second National has de-emphasized its
previous focus on indirect consumer loan lending through local automobile
dealers.
 
1998
 
     Second National Bank continued to enhance its position of leadership in the
financial services marketplace during 1998. Each of the year's management
initiatives was designed to help Second National become increasingly valued by
its stakeholders.
 
GROWTH
 
     The growth of Second National's branch network during 1998 represents a
major milestone for the Bank and Second Bancorp, Inc. This year's de novo
offices and merger and acquisition activity propelled Second National Bank to
$1.43 billion in assets and deposits of $1.1 billion. By year-end 1998, the
Second National branch network grew to 34 offices in seven Ohio counties.
 
                                        1
<PAGE>   3
 
  Acquisitions
 
     Second Bancorp, Inc. announced two separate merger agreements in the spring
of 1998. Both transactions are consistent with Second National's stated growth
plan to become a leader in regional community banking. On April 1, 1998, Second
Bancorp entered into a definitive agreement resulting in the merger of Enfin,
Inc. into Second Bancorp. Following the merger on August 21, Enfin's banking
subsidiary, the $43.7 million Enterprise Bank in Solon, became a Second National
Bank branch. In addition to combining the traditional commercial lending
strengths of both companies, the consolidation marked Second National Bank's
entry into the Solon market, an area that supports thriving business activities
throughout Cuyahoga County.
 
     On May 4, 1998, Second Bancorp, Inc. and Trumbull Financial Corporation
jointly announced the signing of a definitive agreement for the acquisition of
Trumbull Financial by Second Bancorp. On November 20, 1998, Trumbull Financial's
wholly owned subsidiary, the $462 million Trumbull Savings and Loan Company, was
merged into Second National Bank. Like the Second National Bank and Western
Reserve National Bank merger of 1927, Second National's acquisition of Trumbull
Savings was this year's largest financial transaction in the Mahoning Valley.
The merger established Second National as the largest independent bank in the
Mahoning Valley as well as one of its largest employers.
 
  New Branches
 
     In August, Second National opened a new office in Medina, marking the
Bank's entry into yet another Ohio county. From its downtown location, the 1,500
square-foot Medina office will build on an existing customer base and will serve
individual, business, and municipal customers in Medina and nearby Summit
County. The Medina office is staffed by personal bankers, a branch banking
officer, and a commercial lending officer, all providing Second National's brand
of highly personalized, decentralized service. A walk-up ATM, night depository,
and ample parking are available to Medina customers.
 
     The newly constructed Ravenna office opened in March 1998 with a full month
of grand opening activities. The new office, located in a well-traveled portion
of downtown, significantly improved the services and conveniences Second
National provides in Ravenna by offering two drive-thru lanes, a drive-up ATM,
safe deposit boxes, a night depository, and ample parking. With 3,000 square
feet of space, a complete range of products and services, and a specialized
staff of banking professionals, the new Ravenna office is positioned to be a
major competitor in the Portage County market.
 
TECHNOLOGY
 
  Document Preparation System
 
     Second National developed its own document preparation system for deposit
accounts to reduce the paperwork and time associated with opening an account.
"Maxsys," the new document preparation system, allows branch personnel to input
customer and product information once, then print all necessary cards and forms.
The internally produced software, which reduced the time required to open a new
deposit account from 35 minutes to 5 minutes, also provided a significant
savings to the Bank.
 
  Check Imaging
 
     Second National's conversion to check imaging established the Bank as a
leader in the new technology: only 1,600 -- or 20 percent of -- U.S. banks
currently offer this service to their customers. With check imaging, customers
receive a statement featuring digital images of canceled checks, instead of
their actual checks. Not only are image statements a better way for customers to
review checking activity, the new technology will result in greater efficiencies
and cost savings for the Bank.
 
  Branch Teller System
 
     A new branch teller system installed during 1998 makes more features and
functions available to branch personnel, while increasing data processing
efficiencies and meeting all Y2K compliance requirements. The new system brings
a host of advantages to the Bank, including faster processing and better
customer service.
 
                                        2
<PAGE>   4
 
  Relationship Management System (RMS)
 
     The Relationship Management System (RMS), an enhanced ALLTEL Horizon core
application, replaced and represents a significant improvement over the Bank's
Central Information File (CIF). Using this fully functional relational database,
Second National staff can instantaneously capture a comprehensive picture of any
Second National customer -- complete with details of their account
relationships. In addition to significantly enhancing the Bank's ability to
cross-sell, RMS enables management to analyze and evaluate customer account
relationships.
 
  Report Imaging
 
     Instead of printing hundreds of daily Horizon reports, all management
reports are now accessible through CD-ROM. By migrating from printed reports to
report imaging, Second National will recognize significant savings and recoup
all project costs within the first eight months of operation.
 
  Wide Area Network
 
     A wide area network installed during 1998 increased efficiencies in the
management of the Bank's network communications. By connecting individual
branches directly to the AS 400, the network allows transactions to be handled
more efficiently while minimizing down time.
 
DELIVERY
 
  24-Hour Call Center
 
     With the addition of an interactive voice response (IVR) system in 1998,
Second National Bank offers an alternative delivery system for customers who
find it more convenient to bank by phone. Through this new delivery channel,
Second National customers are able to do virtually anything they can do in a
branch -- all via a touch-tone telephone. A bill payment option (available March
1999) will allow customers to pay any bill electronically through the IVR.
 
     In tandem with the IVR, the Bank's Customer Information Center was
redesigned into a telephone banking center staffed with personal bankers. The
Call Center provides high-level, personalized account service and allows
customers to open deposit accounts and apply for loans over the telephone.
 
  ATMs
 
     To enhance customer service and convenience, Second National expanded its
network of automated teller machines by installing 11 additional ATMs. Coupled
with eight machines in newly acquired offices, this initiative brought the total
number of ATMs in the network to 34, and made ATM transactions at the Bank's
terminals totally free for Second National MAC(R) ATM cardholders.
 
PEOPLE
 
     Second National continued its efforts to keep the Bank's core values
foremost in the minds of employees and to inspire its workforce to a high level
of performance. Peer-driven recognition programs remained an important means of
providing Second National employees with the opportunity to define and recognize
excellence in their co-workers. During the "How Far Will Core Values Take You?"
contest of 1998, employees identified more than 10,000 examples of outstanding
performance by their co-workers, and three top employees were rewarded with
trips to Walt Disney World in Orlando, Florida.
 
  Brand
 
     A new marketing communications program, which effectively promoted the
Second National value philosophy in the marketplace, put the spotlight on the
Bank's employees. The advertising campaign and positioning statement, "The
People Making Banking Better," emphasized the quality of Second National
employees and the value they bring to customers. As part of the year's cohesive
marketing efforts, Second
 
                                        3
<PAGE>   5
 
National Bank's corporate identity was also rejuvenated in 1998. The redesigned
logo and corporate colors, which now appear on all signage and communication,
preserved the equity of the Second National mark while giving the Bank visual
prominence in the marketplace.
 
LEADERSHIP
 
  Small Business Lending
 
     Second National Bank was again ranked among the area's top small business
lenders by the U.S. Small Business Administration (SBA). During the SBA's fiscal
year 1998, Second National was the top community bank lender in the Cleveland
district and third among district-wide lenders, ahead of several major financial
institutions.
 
  Trust Division
 
     With innovative programs, expert money management, and outstanding customer
service, the Trust Division continued to make a solid contribution to the
success of Second National Bank.
 
     Once again, Second National ranked among the top money managers in the
country, based on investment returns as of the end of 1998. The Trust Division's
equity pension and profit sharing fund and fixed income pension and profit
sharing fund were both nationally ranked for one- and 10-year returns. 1998
annualized returns were 37.81 percent for the equity fund and 15.34 percent for
the fixed income fund. (Rankings were computed by Nelson's Investment Manager
Database, which evaluates 4,000 investment products from more than 1,500
investment management firms and regularly publishes its results in the World's
Best Money Managers.)
 
     In addition to achieving record levels of trust revenue and asset size, the
Trust Division continued to expand its successful Institutional Trust Program,
which provides trust services to other financial institutions and great
potential for future growth.
 
PRODUCT DEVELOPMENT
 
  ELITE Investment Account
 
     Introduced in 1998, the ELITE Investment Account combines high-yield
investing with the convenience of ATM and checkbook access. The new product
serves as a valuable relationship-builder on the Bank's menu of products and
services. With a high yield, checking privileges, and total liquidity, ELITE was
designed to help Second National compete with other financial institutions in
the marketplace, especially brokerage firms.
 
  Advantage Plus
 
     As part of the Bank's effort to offer customers greater value, it was
determined that the target market for the Advantage Plus Program could be
expanded by developing a true partnership with baby boomers. The age requirement
for this popular package of benefits was reduced from 60 to 50 years old.
 
COMMUNITY
 
     Second National continued to put an educational focus on its efforts in the
community, underwriting an appearance by activist, author, and media commentator
Tavis Smiley at the annual convocation of the Warren City Schools in the summer
of 1998. Mr. Smiley, the host of "BET Tonight with Tavis Smiley" on Black
Entertainment Television, was invited to Warren to address 700 staff members and
members of the community.
 
     The Bank also offered special programs such as "The ABCs of Funding for New
and Small Businesses" for Warren-area business owners and aspiring
entrepreneurs, and "Fellowship Together for Banking Education," a free program
for the public featuring Second National Bank professionals. Other ongoing
activities included the Entrepreneurship Program, the INROADS Career Development
Program, and the Second National Bank Scholarship Fund.
 
                                        4
<PAGE>   6
 
1999
 
     To sustain its continuous improvement and increased stakeholder value,
Second National Bank is committed to improving return on assets and its
efficiency ratio, and to increasing deposits and loans during 1999. To
accomplish these goals, Second National has recommitted to an organization-wide
focus on customer relationships and sales performance and will undertake various
projects to enhance profitability, efficiency, and market share.
 
  Sales Performance
 
     To raise the bar on Second National's sales performance, all employees in
the Bank's sales divisions and branches have been challenged to increase the
sale of profitable products to their existing customers. Throughout the year,
sales employees will execute personal business plans designed expressly to
expand the Bank's single account relationships.
 
  Profitability Analysis
 
     Providing quality products and services that meet customer needs and
wants -- at a fair price and profit -- will further leverage Second National
Bank's value advantage. To increase Second National's profitability analysis
capabilities, the Bank will implement three software modules in 1999:
Profitvision (FTI), Asset and Liability Management (Sendero), and the Executive
Information System (FTI).
 
     Profitvision assists in analyzing the Bank's profitability at multiple
levels and from various viewpoints. The application will serve as an integrated
solution to customer, relationship, product, and organization profitability
management. The Asset and Liability Management module is a modeling system that
will serve as an integrated solution to financial and accounting management for
profit planning and interest rate risk management. The Executive Information
System will provide management with an up-to-the-minute comprehensive overview
of the Bank's condition, as well as detailed information, graphical
presentation, reports, and analysis.
 
     In addition to the analytical benefits these applications will bring to the
management of the Bank, data generated from these modules will help direct
Second National's sales efforts toward more profitable relationships.
 
  Increased Automated Transactions
 
     During 1999, Second National will take steps to maximize the ratio of
automated transactions by encouraging greater use of the ATM, ACH, the IVR/Call
Center, and electronic transfer options. Redirecting manual or repetitive
transactions to automated environments will offer a two-fold benefit to Second
National. A higher ratio of automated transactions will provide branch staff
with more time for sales and service. At a lower per-transaction cost to the
Bank, increased automated transactions will reduce overall costs and ultimately
improve the Bank's efficiency ratio.
 
  Corporate Services
 
     Second National's Corporate Services Division will expand its current menu
of products and services to better suit the needs of small-to-medium size
businesses -- which are expected to increase usage of cash management services
by 38 percent over the next five years. This initiative is designed to make this
important service more competitive in the marketplace and to increase sales to
small businesses.
 
  Growth
 
     During 1999, Second National Bank will establish two de novo offices in
addition to opening a newly constructed and expanded Poland office. This
activity will bring Second National into its ninth Ohio county while further
strengthening the Bank's market position in Summit and Mahoning counties.

  Lake Cable
 
     In the Lake Cable area of Jackson Township in Stark County, Second National
is renovating 1,200 square feet of space in an existing strip shopping center
for a new mini-branch. Lake Cable, a dynamic area with significant mortgage
activity and close proximity to North Canton and Canton, is a natural
progression for Second National that will build on the success of the Bank's
Akron and Green offices in nearby Summit County. In addition to high-level
banking professionals, including a branch manager and commercial lending
officer, the new office will offer a drive-up ATM and a night depository.
 
  Twinsburg
 
     Second National Bank will solidify its Summit County presence with the
opening of an office in Twinsburg, one of the county's fastest growing suburbs.
The new office, which will also have close proximity to our Solon office and
nearby branches in Portage County, is located in a newly constructed building in
front of a retail complex on Route 91. The 3,000 square-foot branch will feature
four teller stations, two personal banker service desks, and three offices for
financial professionals, including a branch manager and a commercial lender. The
full-service Twinsburg branch will also offer safe deposit boxes, a drive-up
ATM, three drive-thru lanes, and a night depository.
 
  Poland Relocation
 
     To accommodate its growing customer base and to take advantage of a prime
office location, Second National is constructing a new building to house the
Bank's Poland branch. The new building, being constructed on the well-traveled
Boardman-Poland Road (Rt. 224), just north of the branch's current location,
will afford the Poland office greater visibility and a broader range of
services.
 
     With 3,000 square feet of office space -- nearly triple the size of the
current office -- the new Poland branch will offer more space for financial
professionals, safe deposit boxes, and four sit-down service desks. The office
will also feature two drive-thru lanes, a night depository, and a drive-up ATM.
 
  Year 2000
 
     The Year 2000 Compliance Plan, designed to provide for the continuance of
all banking and Trust operations through the century date change, encompasses
all current Second National branches and departments while anticipating
acquisitions. Second National has demonstrated its commitment to become fully
Year 2000 compliant by establishing a Y2K Department overseen by a Steering
Committee, allocating resources, and actively involving senior management. The
Bank's Y2K Plan was established using Office of the Comptroller of Currency
(OCC) guidelines that methodically address Year 2000 issues. The Y2K Steering
Committee Chairman provides monthly updates to executive management and reports
at least once each quarter to the Board of Directors.
 
     Identifying critical issues began in the third quarter of 1997 and
established a level of understanding necessary for a project of this
significance. The Y2K Department was established and staffed at the beginning of
1998 to monitor and document progress toward full Year 2000 readiness.
 
     Second National Bank followed OCC guidelines, enabling ease of benchmarking
with examining bodies, including five steps: Awareness, Assessment, Renovation,
Implementation, and Validation. Because of the complex and evolving nature of
Year 2000 information, the Awareness phase was viewed as an ongoing process with
a continuing dialogue to maintain confidence in the Bank by all stakeholders.
Customer awareness was raised through a statement stuffer, informational
brochure, and video. Employees are kept informed through internal memoranda,
articles in the Second Thoughts employee newsletter, reports to committees and
branch personnel, and the establishment of a "You're 2 Kind" award for
extraordinary contributions to the Year 2000 effort.
 
     The Assessment phase included an extensive inventory of the Bank's
technology assets, including computer hardware, software, and peripherals.
Software licenses were collected for central storage in the Network Support
area, and all inventory information was entered into a centralized database for
monitoring and future upgrading.
                                        6
<PAGE>   8
 
     The Renovation phase incorporated testing of the ALLTEL Horizon system and
internal mission critical interfaces. The Implementation phase included
installation of the fully Y2K compliant ALLTEL Horizon core application
software, Southern Data Systems Teller Pro III operating system, and safe
deposit box system. Bank-wide Y2K compliance status will be reached by the end
of the second quarter of 1999.
 
     The Validation phase commenced at the same time as Renovation with random
testing to document that all upgrades installed throughout the Bank were fully
functional and compliant.
 
     Second National Bank recognizes the importance of coordination with outside
entities to ensure a continuous flow of information on Y2K issues. A formal
communication process with vendors, auditors, and regulatory agencies was
established in the third quarter of 1997 and is ongoing. Letters requesting
documentation of Y2K compliance or progress toward that goal were sent to third
party suppliers, including software companies, brokers, utilities, and
environmental services.
 
     A Year 2000 Compliance Assessment worksheet and Year 2000 Customer Risk
Identification guideline were developed to evaluate commercial loan customers'
progress toward Y2K compliant status. The worksheet is a standard part of all
commercial loan packages and trust investor portfolios.
 
  Y2K Contingency Planning
 
     Responsible planning for the century date change must also include the
possibility of both individual sub-system and core processing computer
malfunctions. Hardware upgrades and replacement of non-compliant software,
coupled with testing, make system-wide failure unlikely.
 
     Development of contingency plans and worst-case scenarios was deemed
prudent to enable Second National to minimize risk factors, ensure the safety
and soundness of the financial institution, and lessen or eliminate the
disruption of service to both the Bank and its customers. A Contingency Plan was
written in conjunction with a testing Plan in order to fulfill both OCC
requirements and to complete the Y2K Plan structure. A strategy is in place for
periodic review of the Y2K Contingency Plan.
 
     We believe this approach to the planning and execution of the Y2K Plan will
result in compliance with all Year 2000 standards and will enable Second
National Bank to maintain our industry leadership position into the future.
 
  A Look Ahead
 
     During 1998, Second National uncovered new opportunities to enhance its
value advantage in the Bank's people, technology, and delivery systems; through
leadership and growth; and within the Bank's community banking philosophy.
 
     The sum total of those efforts afforded Second National customers more
convenient and comprehensive products and services. For shareholders, the Bank's
pursuit of value translated into greater efficiencies and increased
competitiveness. By leveraging an expert workforce and the synergies of its
growing branch network, Second National benefitted all of its stakeholders.
 
     In 1999, Second National will aggressively pursue the opportunities created
during 1998 -- and continue to excel in its financial services niche.
 
     The Company has no significant industry segments which require disclosure.
 
MARKET AREA
 
     Second National's primary market area consists of Trumbull, Mahoning,
Portage, Jefferson, Summit, Medina, Ashtabula and the southeast portion of
Cuyahoga counties in the northeastern corner of Ohio, to the east and south of
the Cleveland metropolitan area. The market area's economy is heavily influenced
by the manufacturing sector with an emphasis on steel, auto manufacturing and a
variety of related and smaller industries. The area has benefited from an
extensive transportation system comprised mainly of railroad and trucking
systems.

COMPETITION
 
     There is significant competition in the financial services industry in
northeastern Ohio among commercial banks. As a result of deregulation of the
financial services industry, Second Bancorp also competes with other providers
of financial services such as savings and loan associations, credit unions,
commercial finance companies, brokerage and securities firms, insurance
companies, commercial finance and leasing companies and the mutual fund
industry. Some of Second Bancorp's competitors, including certain regional bank
holding companies which have operations in Second Bancorp's market area, have
substantially greater resources than Second Bancorp, and as such, may have
higher lending limits and may offer other services not available through Second
National. Second Bancorp also faces significant competition, particularly with
respect to interest rates paid on deposit accounts, from well-capitalized local
thrift institutions. Second National competes on the basis of rates of interest
charged on loans, the rates of interest paid on funds, the availability of
services and responsiveness to the needs of its customers.
 
REGULATION
 
     Second Bancorp is a one bank holding company and is regulated by the
Federal Reserve Bank (the "FRB"). Second National is a national bank and is
regulated by the Office of the Comptroller of the Currency (the "OCC"), as well
as the Federal Deposit Insurance Corporation (the "FDIC"). Dramatic changes have
developed over the past several years regarding minimum capital requirements for
financial institutions. A listing of the minimum requirements for capital and
Second Bancorp's capital position as of December 31, 1998 and 1997 are presented
in footnote 12 of Item 8; Financial Statements and Supplementary Data and is
hereby incorporated by reference.
 
     Second Bancorp is subject to regulation under the Bank Holding Company Act
of 1956, as amended (the "Act"). The Act restricts the geographic and product
range of bank holding companies by circumscribing the types and locations of
institutions the holding companies own or acquire. Among the states where Second
Bancorp may acquire banks are Ohio and Pennsylvania. The Act also regulates
transactions between Second Bancorp and Second National and generally prohibits
tie-ins between credit and other products and services.
 
     Second National is subject to regulation under the National Banking Act and
is periodically examined by OCC and is subject, as a member bank, to the rules
and regulations of the FRB. Second National is an insured institution and member
of the Bank Insurance Fund ("BIF") and also has approximately $435 million in
deposits acquired through acquisitions of savings and loan institutions that are
insured through the Savings Association Insurance Fund ("SAIF"). As such, Second
National is also subject to regulation by the FDIC. Establishment of branches is
subject to approval of the OCC and geographic limits established by state law.
 
FIRREA
 
     FIRREA restructures the regulation, supervision and deposit insurance of
savings and loan associations and federal savings banks whose deposits were
formerly insured by the Federal Savings and Loans Insurance Corporation
("FSLIC"). FSLIC was replaced by the Savings Association Insurance Fund ("SAIF")
administered by the FDIC. A separate fund, the Bank Insurance Fund ("BIF"),
which was essentially a continuation of the FDIC's then existing fund, was
established for banks and state savings banks. An acquired thrift generally
would be required to continue its deposit insurance with the SAIF unless
significant exit and entrance fees were paid in connection with a conversion to
BIF insurance.
 
FDICIA
 
     The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA") substantially revised the bank regulatory and funding provisions of
the Federal Deposit Insurance Act and several other federal banking statutes.
Among other things, FDICIA requires federal banking agencies to broaden the
scope of regulatory corrective action taken with respect to banks that do not
meet minimum capital requirements and to take such actions promptly in order to
minimize losses to the FDIC. FDICIA established five capital tiers: "well
capitalized"; "adequately capitalized"; "undercapitalized"; "significantly
capitalized"; and "critically undercapitalized" and imposes significant
restrictions on the operations of a depository institution that is not in either
                                        8
<PAGE>   10
 
of the first two of such categories. A depository institution's capital tier
will depend upon the relationship of its capital to various capital measures. A
depository institution will be deemed to be "well capitalized" if it
significantly exceeds the minimum level required by regulation for each relevant
capital measure, "adequately capitalized" if it meets each such measure,
"undercapitalized" if it is significantly below any such measure and "critically
undercapitalized" if it fails to meet any critical capital level set forth in
regulations. An institution may be deemed to be in a capitalization category
that is lower than is indicated by its actual capital position if it receives an
unsatisfactory examination rating or is deemed to be in an unsafe or unsound
condition or to be engaging in unsafe or unsound practices.
 
     Under regulations adopted under these provisions, for an institution to be
well capitalized it must have a total risk-based capital ratio of at least 10%,
a Tier I risk-based capital ratio of at least 6% and a Tier I leverage ratio of
at least 5% and not be subject to any specific capital order or directive. For
an institution to be adequately capitalized, it must have a total risk-based
capital ratio of at least 8%, a Tier I risk-based capital ratio of at least 4%
and a Tier I leverage ratio of at least 4% (or in some cases 3%). Under the
regulations, an institution will be deemed to be undercapitalized if the bank
has a total risk-based capital ratio that is less than 8%, a Tier I risk-based
capital that is less than 4% or a Tier I leverage ratio of less than 4% (or in
some cases 3%). An institution will be deemed to be significantly
undercapitalized if the bank has a total risk-based capital ratio that is less
than 6%, a Tier I risk-based capital ratio that is less than 3%, or a leverage
ratio that is less than 3% and will be deemed to be critically undercapitalized
if it has a ratio of tangible equity to total assets that is equal to or less
than 2%.
 
     FDICIA generally prohibits a depository institution from making a capital
distribution (including payment of dividends) or paying management fees to any
entity that controls the institution if it thereafter would be undercapitalized.
If an institution becomes undercapitalized, it will be generally restricted from
borrowing from the Federal Reserve, increasing its average total assets, making
any acquisitions, establishing any branches or engaging in any new line of
business. An undercapitalized institution must submit an acceptable capital
restoration plan to the appropriate federal banking agency, which plan must, in
the opinion of such agency, be based on realistic assumptions and be "likely to
succeed" in restoring the institution's capital. In connection with the approval
of such a plan, the holding company of the institution must guarantee that the
institution will comply with the plan, subject to a limitation of liability
equal to a portion of the institution's assets. If an undercapitalized
institution fails to submit an acceptable plan or fails to implement such a
plan, it will be treated as if it is significantly undercapitalized.
 
     Under FDICIA, bank regulators are directed to require "significantly
undercapitalized" institutions, among other things, to restrict business
activities, raise capital through a sale of stock, merge with another
institution and/or take any other action which the agency determines would
better carry out the purposes of FDICIA.
 
     Within 90 days after an institution is determined to be "critically
undercapitalized", the appropriate federal banking agency must, in most cases,
appoint a receiver or conservator for the institution or take such other action
as the agency determines would better achieve the purposes of FDICIA. In
general, "critically undercapitalized" institutions will be prohibited from
paying principal or interest on their subordinated debt and will be subject to
other substantial restrictions.
 
     FDICIA also contains a variety of other provisions that could affect the
operations of Second Bancorp, including new reporting requirements, regulatory
standards for real estate lending, "truth in savings" provisions, the
requirement that a depository institution give 90 days' prior notice to
customers and regulatory authorities before closing any branch, limitations on
credit exposure between banks, restrictions on loans to a bank's insiders and
guidelines governing regulatory examinations.
 
DEPOSIT INSURANCE ASSESSMENTS AND RECENT LEGISLATION
 
     The FDIC is authorized to establish separate annual assessment rates for
deposit insurance for members of the BIF and the SAIF. The FDIC may increase
assessment rates for either fund if necessary to restore the fund's ratio of
reserves to insured deposits to its target level within a reasonable time and
may decrease such rates if such target level has been met. The FDIC has
established a risk-based assessment system for both BIF and SAIF members. Under
this system, assessments vary based on the risk the institution poses to its
deposit insurance
                                        9
<PAGE>   11
 
fund. The risk level is determined based on the institution's capital level and
the FDIC's level of supervisory concern about the institution.
 
     Based upon its respective level of deposits at December 31, 1998, the
projected BIF and SAIF assessments for Second National for 1999 will be
approximately $330,000.
 
INTERSTATE BANKING AND BRANCHING LEGISLATION
 
     The Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994
(the "IBBEA") authorized interstate acquisitions of banks and bank holding
companies without geographic constraint beginning September 29, 1995. Beginning
June 1, 1997, the IBBEA also authorizes banks to merge with banks located in
another state provided that neither state has "opted out" of interstate
branching between September 29, 1994 and May 31, 1997. States could also enact
legislation permitting interstate merger transactions prior to June 1, 1997.
After acquiring interstate branches through a merger, a bank may establish
additional branches in that state at the same locations as any bank involved in
the merger could have established branches under state and federal law. In
addition, a bank may establish a de novo branch in another state that expressly
permits the establishment of such branches. A bank that establishes a de novo
interstate branch may thereafter establish additional branches on the same basis
as a bank that has established interstate branches through a merger transaction.
 
     If a state "opts out" of interstate branching, no bank from another state
may establish a branch in that state, whether through a merger of de novo
establishment. Pennsylvania, the state in closest proximity to Second National,
has opted to permit interstate branching, creating the possibility of branching
into that state. To date, Second National has taken no action to branch into
Pennsylvania or any other state, however Second National may do so in the
future.
 
EMPLOYEES
 
     The number of full time equivalent employees of Second Bancorp as of
December 31, 1998 was approximately 544. Second Bancorp considers its employee
relations to be good. None of the employees are covered by a collective
bargaining agreement.
 
ITEM 2.  PROPERTIES
 
     Second Bancorp's executive offices are located at Second National's main
office building in Warren, Ohio, which is leased by Second National under a
long-term triple net lease agreement with a term, including optional renewals,
expiring on October 31, 2029. Second National has the option to purchase the
main office facility before two optional renewal periods at the fair market
value in existence at that time. Second National owns six of its branch
locations, while Second National's 28 other branch and loan production office
locations are leased under lease and sublease agreements with remaining terms of
1 to 15 years. Second National also has leases for record retention and office
space with remaining lease terms of two and eight years, respectively.
 
ITEM 3.  LEGAL PROCEEDINGS
 
     Second Bancorp is subject to various pending and threatened lawsuits in
which claims for monetary damages are asserted in the ordinary course of
business. While any litigation involves an element of uncertainty, in the
opinion of management, liabilities, if any, arising from such litigation or
threat thereof will not have a material effect on the financial position or
results of operations of Second Bancorp.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS
 
(DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
RESULTS OF OPERATIONS
 
     Net income for 1998 was $5,633 and was affected by the merger activity
completed in 1998. The acquisition of Trumbull Financial Corporation,
headquartered in Warren, Ohio, and Enfin Corporation, headquartered in Solon,
Ohio, greatly increased the Corporation's asset size and earnings capacity for
the future. During 1998, however, merger related costs of $6,657 were taken to
accomplish the strategic growth. The acquisition of Enfin gives the Corporation
access to the commercial lending market in and around Solon, a suburb of
Cleveland, while the acquisition of Trumbull strengthens the Corporation's
dominance of the Trumbull County market. Also impacting earnings during 1998 was
the need to provide additional provision for loan losses. Net losses incurred
 
                                       13
<PAGE>   15
 
during 1998, primarily commercial loan losses, exceeded $8.6 million for the
year, necessitating the increase in provision. Absent the merger costs and
related tax impact, net income for 1998 would have been $10,630. Net income for
1997 was $13,236 and was 37% greater than net income reported in 1996 of $9,669.
The net income for 1996 was impacted by the special one-time SAIF assessment
totaling $2,471. The Corporation's return on average assets ("ROA") was .38%,
 .93%, and .70% for 1998, 1997, and 1996, respectively. Excluding merger costs,
ROA would have been .73% in 1998. The total shareholders' return on average
equity ("ROE") was 4.44% in 1998 compared to 11.80% in 1997 and 9.32% in 1996.
An increase in common stock of nearly $1.2 million was generated through the
dividend reinvestment program in both 1998 and 1997, thereby increasing the
shareholders' equity balances.
 
     Basic earnings per common share were $.53 per share in 1998, down from
$1.25 in 1997. Basic earnings per share were $.93 in 1996. Diluted earnings per
share, which takes into effect the dilutive impact of the preferred stock which
was present through mid-1996 and other dilutive securities, were $.52 per share
in 1998, $1.25 in 1997, and $.92 in 1996. The Corporation declared a two-for-one
stock split for the common stock effective May 1, 1997. The Corporation's common
stock, trading under the NASDAQ symbol of SECD, has generally followed the path
of most bank stocks during 1998, peaking at $37.25 per share in the second
quarter and finishing the year at $22.25 per share. The stock price at year-end
1998 represents a price of 193% of book value. Dividends declared in 1998
totaled $.48 per share. This represents an increase of 20% over 1997, when
dividends declared were $.40 per share.
 
     Revenue continues to be provided primarily from interest and fees on loans,
which totaled $79,963, $74,145, and $70,611 in 1998, 1997, and 1996,
respectively. This represents 67%, 64%, and 64% of total revenues for those
years. Interest income on securities is also a major source of revenue,
contributing 22%, 26%, and 27% of revenues in 1998, 1997, and 1996,
respectively. The shift to a greater concentration in earnings from loans
reflects the Corporation's efforts to more profitably employ the funds available
to it.
 
NET INTEREST INCOME
 
     The Corporation was able to increase the net interest income in 1998
through an improvement in the net interest margin and an increase in average
earning assets. The net interest margin improved from 3.78% in 1997 to 3.84% in
1998. Net interest income increased by 3.7% from $49,283 in 1997 to $51,109 in
1998. Average earning assets increased by 2.6% to $1,386,894 in 1998. Similarly,
net interest income increased by 4.8% from 1996 to 1997 while average earning
assets increased by 3.8% and the net interest margin increased from 3.73% in
1996 to 3.78% in 1997. The Corporation continues to face tightening pressures on
the net interest margin; however, the Corporation has reacted proactively to
achieve a higher net interest margin, primarily through loan growth. Average
loans, primarily real estate mortgage loans, have increased consistently over
the past four years, growing at an average annual rate of 9%. Deposits averaged
$1,086,074 in 1998, representing a 1% increase over 1997.
 
     The relationship between net interest income, FTE net interest income,
earning assets, and net interest margin for the past three years follows:

(1) The change in interest due to both rate and volume has been allocated to
    volume and rate changes in proportion to the relationship of the absolute
    dollar amounts of the change in each.
 
PROVISION FOR LOAN LOSSES
 
     The provision for loan losses totaled $10,579 in 1998, or .92% of average
loans, significantly higher than the average level of .52% over the past five
years. The provision for loan losses was $4,205 in 1997, $5,072 in 1996, $3,176
in 1995, and $2,463 in 1994. The increase in 1998 can be attributed to higher
than historically normal levels of net charge-offs for the commercial loan
portfolio. Net charge-offs as a percent of average commercial loans were 1.55%
in 1998 and .68% in 1997.
 
NON-INTEREST INCOME
 
     Non-interest income totaled $12,754 in 1998, which represented a 15%
increase over 1997. Service charges on deposit accounts improved by 5% to $4,145
in 1998. The increase is attributable to the increase in revenue from ATM
services provided and improvements in the collection of return check and
overdraft fees. Service charges on deposits had increased 17% from 1996 to 1997.
Trust fee income totaled $2,820 in 1998, a 10% improvement over the prior year.
The revenue increase was partly attributable to new trust relationships as well
as increases in the market value of assets under management. Trust fee income
was $2,562 in 1997 and $2,335 in 1996. Other fee income increased by 18% during
1998 and included gains from the sale of mortgages and Small Business
Administration ("SBA") loans. Other income had increased by 6% the prior year
through the combination of earnings from secondary mortgage and SBA sale
activities.

     Included in non-interest income over the past three years were pre-tax
gains on the sale of securities. During 1998, the security portfolio realized
gains in the amount of $1,007. During 1997, the Corporation established a
charitable foundation to carry on the Corporation's many charitable and civic
activities. The gain realized on the appreciated stock donated to the foundation
was $352, which represented a significant portion of the total gains realized in
1997 of $515.
 
NON-INTEREST EXPENSE
 
     The Corporation continues to emphasize expense control and to be efficient
in its utilization of resources to manage assets. Excluding merger costs,
non-interest expenses as a percentage of average assets were 2.70% in 1998
compared to 2.75% in 1997. The table below details the percentage change in each
non-interest expense category over the past three years:

</TABLE>
 
     Equipment expense increased by 13% in 1998, due primarily to the costs
associated with automation efforts during the past two years. During 1997, the
Corporation migrated to an in-house data processing environment, while in 1998,
the Corporation continued implementing new technologies and upgraded the
acquired companies' equipment to newer technologies. In 1997, excluding the
one-time charge for donating $824 of stock to the charitable foundation, other
expenses would have actually decreased by 1%.
 
INCOME TAXES
 
     The provision for income taxes was $1,403, $3,745, and $2,993 in 1998,
1997, and 1996, respectively. The effective tax rate for the Corporation was
19.9%, 22.1%, and 23.6% during the same periods. The reduction in the effective
tax rate in 1997 and 1998 was due to the continuation of the accumulation of
tax-exempt securities and the realization of investment tax credits through the
Bank's participation in low-income housing projects as well as reduced net
income for 1998.
 
BALANCE SHEET
 
     The average asset growth rate has averaged 5% over the past four years. The
1998 growth rate in average assets was 2.9%. The slower growth rate is
attributable to the planned de-emphasis of the indirect automobile lending
program. Also as an industry, banks are experiencing slower deposit growth rates
due to increased competition from non-traditional alternatives, especially
mutual funds. Deposit balances finished the year totaling in excess of $1.1
billion, representing a decrease of 1% from the previous year-end. Deposits grew
3.5% from December 31, 1996 to December 31, 1997.
 
EARNING ASSETS
 
  Securities:
 
     The securities portfolio of the Corporation is used to provide an adequate
rate of return to the Corporation along with appropriate levels of liquidity and
as a tool for efficient tax management and interest rate risk management. The
accounting treatment for the securities portfolio is determined by the
Corporation's intent regarding particular security holdings. Securities
held-to-maturity are purchased with the intent and ability to
 
                                       17
<PAGE>   19
 
hold them to maturity and are, therefore, carried at amortized cost. Securities
previously classified as held-to-maturity by Trumbull were reclassified to
available-for-sale at the consummation of the transaction. Securities are
purchased to satisfy yield enhancement, liquidity, interest rate risk
management, and pledging needs. Purchases in longer maturities that provided
yield enhancement included purchases of tax-exempt securities which provide the
additional benefit of tax reduction.
 
     The securities portfolio totaled $354,415 as of December 31, 1998. That
balance represents a 26% decrease over the prior year-end. The December 31, 1997
balance of $483,095 included $312,328 classified as available-for-sale and was
2% less than the prior year-end. Security balances have been declining as the
Corporation increases its loan balances. Growth in securities has been
concentrated in tax-exempt issues. Mortgage-backed securities have declined
significantly over the past year as market rates are lower and mortgage
refinancings have risen.
 
     The average yield on the portfolio is 6.5% as of December 31, 1998. During
the past year, the Corporation realized $1,007 in net gains on the sale of
securities. In 1997 and 1996, net security gains totaled $515 and $462,
respectively. As interest rates have declined over the past year, the
Corporation's net unrealized gain or loss position for the portfolio has
increased from $3,387 to $4,695.
 
     Summary yield and maturity information regarding the securities portfolios
on December 31 follows. Yields are calculated on a fully taxable equivalent
basis using the marginal Federal income tax rate of 34% for 1998.

     The Corporation emphasizes growth in real estate loans and commercial
balances. The Corporation emphasizes real estate lending through its branch
network, reaching a broad range of customers. The Corporation has benefited from
this approach along with the use of mortgage loan originators and correspondent
lender relationships. Generally, the loans sold into the secondary mortgage
market make funds available for reuse in mortgage or other lending activities,
generate a net gain (including origination fee income) from the sale, limit the
interest rate risk caused by holding long-term, fixed-rate loans, and build a
portfolio of serviced loans which generate fee income for the Corporation. The
serviced portfolio of mortgages totaled $295 and $377 million as of December 31,
1998 and 1997, respectively.
 
     Commercial loans are generated through a calling program targeting
medium-size companies. The Corporation is also generating an increasing volume
of Small Business Administration ("SBA") loans. The Corporation sells the
guaranteed portion of the SBA loans originated. The sales generated $658 and
$498 in net revenues, including $173 and $143 in revenues from the value of the
servicing retained in 1998 and 1997, respectively. The amount of SBA loans being
serviced by the Corporation totaled approximately $10.4 and $7.7 million at
December 31, 1998 and 1997, respectively.
 
     The Bank de-emphasized its indirect lending program with automobile dealers
within the Bank's primary market areas in 1996, choosing to permit more funds to
be available to allow for commercial and real estate loan growth. In 1996, the
Bank shifted its focus on indirect lending, strictly limiting the acquisition of
lower-quality "C" and "D" type paper. Prior to that, the Bank accepted a higher
volume of lower-quality paper utilizing a tiered pricing system designed to
compensate the Bank for the higher risk associated with the loans. The Bank is
still active in generating loans from automobile dealers within the Bank's
market area; however, future growth is targeted in higher-quality loans.
 
     The Corporation's loans are granted to customers within the immediate trade
area of the Corporation. The mix is diverse, covering a wide range of borrowers.
The Corporation monitors and controls concentrations within a particular
industry or segment. As of December 31, 1998, the Corporation had a
concentration in commercial real estate loans totaling approximately $258
million, approximately 68.5% of which were owner-occupied businesses, including
medical office buildings, retail, and fast-food restaurants within the
Corporation's market area.

     Significantly impacting the reserve for loan losses in 1998 was net
charge-off activity totaling $8.7 million, substantially from the commercial
lending portfolio. The losses and additional provision for loan losses were
associated with analysis of specific credits. Additionally, the majority of the
charge-offs occurred in the fourth quarter of 1998, following a detailed review
of all problem credits and additional adverse information regarding the
charged-off credits. Included in 1997's activity was the reclassification of
$2.4 million from loans to other assets. During 1997, one of the Bank's
borrowers, whose loan balance was included in non-performing loans as of
December 31, 1996, settled all their obligations with the Bank by placing
approximately $2.7 million in a third party trust. The balance was substantially
collected during 1998.

</TABLE>
 
     The increase in the loan loss reserve allocation to the commercial category
is the result of allocation to specific problem credits. The decrease in the
loan loss allowance allocated to consumer loans is the result of the run-off of
lower quality "C" and "D" type paper and the corresponding reduction in loss
experience. The increase in allocation of the loan loss allowance to real estate
loans reflects growth in loan balances from the Trumbull acquisition.
 
     The determination of the reserve for loan losses is based on Management's
evaluation of the potential losses in the loan portfolio considering, among
other relevant factors, repayment status, borrowers' ability to repay,
collateral, and current and foreseeable economic conditions. The Bank utilizes
its internal loan gradings for commercial loans in conjunction with historical
loss experience for loans of each grade level and current economic trends as
parts of its analysis in determining the adequacy of its reserve for loan
losses. During the course of the year, the Corporation continued to update the
factors used in determining the appropriate level of loan losses for each major
category of loans based on loss experience within each category of loans.

     Loans 30 to 89 days past due, excluding non-accrual and restructured loans
included in the table above, amounted to $8,706, or .90% of outstanding loans,
as of December 31, 1998, as compared to $10,273, or 1.18% of loans on December
31, 1997. Loans then current where some concerns existed as to ability of the
borrower to comply with loan repayment terms approximated $28,352 on December
31, 1998 and $33,779 on December 31, 1997. Such loans have been and are being
closely monitored by Management.

     Average deposits increased by 1% in 1998 with slight increases in average
time deposits and interest bearing demand deposits. During 1997, non-interest
bearing demand deposits increased through the introduction of a "totally free"
checking product along with increased balances from corporate customers. Savings
deposits declined in both 1998 and 1997 as customers chose to seek higher
yielding alternatives.
 
     On December 31, 1998, time deposits over $100 totaled $79,434. The Bank
continues to maintain strong relationships with the various public entities
centered in the primary markets of the Bank which contribute to the balance of
time deposits over $100. The maturity schedule for time deposits over $100 as of
December 31 is given in the table below:

Other Sources of Funds:
 
     The repurchase agreement program provides a sweep feature on the customer's
primary business account, along with competitive market rates of interest, for
their excess funds. The success of this product reflects the strong emphasis the
Bank places on offering competitive products, coupled with personalized service
to the small- to mid-size businesses operating in the Bank's various markets.
Federal funds purchased and securities sold under agreements to repurchase
averaged $135 million in 1998 with the majority of the average balances
representing the retail sweep product.
 
     The Corporation also has available to it unsecured lines of credit with
correspondent banks totaling $15 million. The lines of credit are renewable
annually and bear interest at a floating rate based on several indices. There
were no outstanding borrowings under these lines as of December 31, 1998 or
1997.
 
     The Corporation also has access to federal tax deposits on a daily basis.
After being deposited by customers, the tax deposits are held at the Corporation
up to a self-imposed limit of $6 million until they are drawn upon by the
federal government. The balance of these funds was $861 and $3,492 as of
December 31, 1998 and 1997, respectively. The Corporation occasionally uses
federal funds purchased from other financial institutions as a source of
short-term funding. The Corporation had no federal funds purchased as of
December 31, 1998 or 1997.
 
     The Bank also is a member of the Federal Home Loan Bank ("FHLB") system and
utilizes the various advance programs offered by the FHLB. The funds are drawn
from the FHLB for various terms through 2007 and

are utilized to provide long-term funding to offset the interest rate risk
inherent with holding long-term, fixed-rate mortgages. The balances of these
advances were $72,782 and $58,403 as of December 31, 1998 and 1997,
respectively.
 
CAPITAL
 
     The shareholders' equity increased to $123,273 at December 31, 1998 from
$120,318 a year earlier. The increase was primarily attributed to the earnings
retained this year after common stock dividend payments. In 1997, shareholders'
equity increased by $13,903 primarily through earnings retention and SFAS No.
115 adjustments. The impact of the change in unrealized market value adjustment
on securities available-for-sale, net of tax (SFAS No. 115 adjustment) resulted
in a net unrealized gain position of $3,097 at December 31, 1998 versus a net
unrealized gain position of $2,813 at December 31, 1997. The Corporation also
increased common stock by $1,170 through the dividend reinvestment program in
1998 and by $1,183 in 1997. Shareholders may invest cash dividends and voluntary
cash payments in additional shares at a 5% discount without payment of brokerage
commissions or service charges. Common stock was also increased by the exercise
of $377 of options. In 1997, common stock increased by $717 due to option
exercise activities. In 1997, $474 of treasury stock was repurchased, while in
1996 the repurchase totaled $319. On February 27, 1998, the Board of Directors
rescinded the authorization to repurchase shares of its common stock. As of
December 31, 1998, the Corporation had repurchased 50,400 shares. Effective June
25, 1996, the Corporation called for the redemption of all the outstanding
shares of the Series A $1.50 preferred stock. Virtually all preferred
stockholders exercised their conversion rights prior to the redemption date. The
net effect was a transfer of approximately $12.7 million in capital from
preferred stock to common stock.
 
     The Corporation has consistently had qualifying capital under the
risk-based capital requirements in excess of those required to meet the
"well-capitalized" standards. For further details on capital ratios, see Note
12.
 
     The Corporation trades under the symbol SECD on the NASDAQ National Market
System. The total market capitalization of the Corporation was approximately
$237.8 million at December 31, 1998. The table below lists the high and low
trading prices for the common stock by quarter for the last three years. The
price ranges and per share dividend figures set forth below have been adjusted
to reflect the two-for-one stock split effective May 1, 1997.

     The Corporation's price for its common stock increased to a trading range
of $27.00 to $37.25 per share in the second quarter of 1998 and subsequently
closed the year at $22.25. The Corporation's stock has generally followed the
market trend for traded bank stocks. The common stock closed at $25.38 at
December 31, 1997, representing a 62% increase from the 1996 year-end close.
Book value per common share was $11.53 and $11.34 at December 31, 1998 and 1997,
respectively.
 
     The Corporation has historically paid cash dividends on a quarterly basis
and has periodically paid stock dividends at the discretion of the Board of
Directors. The payment and amount of future dividends on the
 
                                       23
<PAGE>   25
 
common stock will be determined by the Board of Directors. The payment will
depend on, among other things, earnings, financial condition, and cash
requirements of the Corporation at the time that such payment is considered, and
on the ability of the Corporation to receive dividends from the Bank, the amount
of which is subject to regulatory limitations. For 1998, 1997, and 1996, the
dividend-payout ratio for the Corporation was 91.53%, 32.29%, and 35.77%,
respectively.
 
LIQUIDITY
 
     Management of the Corporation's liquidity position is necessary to ensure
that funds are available to meet the cash flow needs of depositors and borrowers
as well as the operating cash needs of the Corporation. Funds are available from
a number of sources including maturing securities, payments made on loans, the
acquisition of new deposits, the sale of packaged loans, borrowing from the
FHLB, and overnight lines of credit of over $37 million through correspondent
banks. The parent company has three major sources of funding, including
dividends from the Bank, $15 million in unsecured lines of credit with
correspondent banks which are renewable annually, and access to the capital
markets. The net cash provided by operating activities for 1998, 1997, and 1996
were approximately $4 million, $17 million, and $19 million, respectively. As
discussed in Note 12, the Bank is subject to regulation and may be limited in
its ability to pay dividends to the parent company. Accordingly, consolidated
cash flows may not represent cash available to common stockholders.
 
     Additional discussion regarding the Company's liquidity and capital
resources is set forth in Notes 10, 11, and 12 of Item 8; Second Bancorp's
Financial Statements and Supplementary Data are incorporated herein by

FORWARD-LOOKING STATEMENTS
 
     The sections that follow, Market Risk Management and Other, contain certain
forward-looking statements (as defined in the Private Securities Litigation
Reform Act of 1995). These forward-looking statements may involve significant
risks and uncertainties. Although the Corporation believes that the expectations
reflected in such forward-looking statements are reasonable, actual results may
differ materially from these results discussed in these forward-looking
statements.
 
MARKET RISK MANAGEMENT
 
     Market risk is the risk of economic loss from adverse changes in the fair
value of financial instruments due to changes in (a) interest rates, (b) foreign
exchange rates, or (c) other factors that relate to market volatility of the
rate, index, or price underlying the financial instrument. The Corporation's
market risk is composed primarily of interest rate risk. The Corporation's
Asset/Liability Committee (ALCO) is responsible for reviewing the interest rate
sensitivity position of the Corporation and establishing policies to monitor and
limit the exposure to interest rate risk. Since nearly the Corporation's entire
interest rate risk exposure relates to the financial instrument activity of the
Bank, the Bank's Board of Directors reviews the policies and guidelines
established by ALCO.
 
     The primary objective of asset/liability management is to provide an
optimum and stable net interest margin, after-tax return on assets and return on
equity capital, as well as adequate liquidity and capital. Interest rate risk is
monitored through the use of two complementary measures: dynamic gap analysis
and earnings simulation models. While each of the measurement techniques has
limitations, taken together they represent a reasonably comprehensive tool for
measuring the magnitude of interest rate risk inherent in the Corporation.
 
     The dynamic gap analysis measures the amount of repricing risk associated
with the balance sheet at a specific point in time. Expected cash flows from
fixed rate instruments are defined utilizing contractual maturities and
anticipated cash flows through early repayment of loans, early calls and
paydowns of securities, and early withdrawals of deposits. Variable rate
instrument's repricing frequencies are categorized according to their earliest
repricing opportunity. Core deposits with noncontractual maturities are included
in the gap repricing distributions based on historical patterns of pricing
behavior.
 
     The earnings simulation model forecasts earnings for a one-year horizon
frame under a variety of interest rate scenarios. Management evaluates the
impact of the various rate simulations against earnings in a stable
 
                                       24
<PAGE>   26
 
interest rate environment. The most recent model projects net income would
increase by 6.5% if interest rates would immediately rise by 200 basis points.
It projects a decrease in net income of 3.8% if interest rates would immediately
fall by 200 basis points. Management believes this reflects a slight asset
sensitive position for the one-year time horizon. The earnings simulation model
includes assumptions about how the various components of the balance sheet and
rate structure are likely to react through time in different interest rate
environments. These assumptions are derived from historical analysis and
Management's outlook.
 
     Interest rate sensitivity is managed through the use of security portfolio
management techniques, the use of fixed rate long-term borrowings from the FHLB,
the establishment of rate and term structures for time deposits and loans, and
the sale of long-term fixed rate mortgages through the secondary mortgage
market. Although the Corporation has available to it the use of off-balance
sheet swap instruments to manage interest rate risk, these instruments are
historically rarely utilized. Management expects interest rates to be relatively
stable during 1999 and believes that the current modest level of asset
sensitivity is appropriate.
 
OTHER
 
  Year 2000:
 
     The Corporation has initiated the process of preparing its computer systems
and applications for the Year 2000. This process involves modifying or replacing
certain hardware and software used by the Corporation. The software utilized is
primarily originated and serviced by external providers. The Corporation is
communicating with those providers to ensure that appropriate steps are being
taken to remedy any Year 2000 issues. Management has completed the awareness and
inventory stages of the process and is substantially complete with the process
assessment, analysis, and conversion phases of the efforts. The process
assessment included a review of the information systems used in each process,
including related hardware and software, the involvement of third parties, and
any affected systems. Management expects to have all necessary system and
application changes implemented and tested in 1999. Management is also working
with significant customers, vendors, and business counterparties to monitor the
progress of their Year 2000 efforts. Management believes it has an effective
plan in place to resolve the Year 2000 issue in a timely manner and, thus far,
activities have tracked in accordance with original plans. Under the unlikely
scenario that the additional phases to the Year 2000 efforts are not completed,
the Corporation could be materially adversely affected as a result of not being
able to process transactions related to its business activities. In addition,
non-compliance by third parties (including loan customers) and disruptions to
the economy in general resulting from Year 2000 issues could also have a
negative impact of undeterminable magnitude on the Corporation. Total cost
associated with the process, including the cost of acquiring certain hardware
and software and the internal and external costs relating to modifying the
systems, will be approximately $880. In 1998, $370 of that total was expended,
with the balance to be spent in 1999. Additionally, the impact on operating
costs in 1998 was not material, and less than $100 is anticipated to be expended
in 1999. Purchased hardware and software will be capitalized in accordance with
normal policy. Personnel and all other costs related to the process are being
expensed as incurred. The costs of the process and the expected completion dates
are based on Management's best estimates.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                 (DOLLARS IN THOUSANDS, EXCEPT PER SHARE DATA)
 
                               DECEMBER 31, 1998
 
1.  STATEMENT OF ACCOUNTING POLICIES
 
     Nature of Operations: Second Bancorp, Inc. (the Corporation) is a one bank
holding company with its sole subsidiary being The Second National Bank of
Warren (the Bank), headquartered in Warren, Ohio, with 33 branches and one loan
production office operating in Northeast Ohio. In addition to general commercial
banking, the Bank engages in trust and mortgage banking activities and other
financially related businesses.
 
     The accounting policies followed by Second Bancorp, Inc. conform to
generally accepted accounting principles and to general practices within the
banking industry. The following is a description of the more significant
accounting policies:
 
      a. Principles of Consolidation: Significant intercompany balances and
         transactions between the Corporation and the Bank have been eliminated.
         The consolidated financial statements have been prepared to give
         retroactive effect to the August 20, 1998 acquisition of Enfin, Inc.
         (Enfin) and to the November 19, 1998 acquisition of Trumbull Financial
         Corporation (Trumbull). In accordance with the rules of the Securities
         and Exchange Commission, Trumbull's financial statements and selected
         financial data for the years ended September 30, 1994 through 1997 have
         been combined with the Corporation's financial statements and selected
         financial data for the years ended December 31, 1994 through 1997,
         respectively. Certain prior year amounts have been reclassified to
         conform with the current year presentation.
 
      b. Use of Estimates: The preparation of the financial statements in
         conformity with generally accepted accounting principles requires
         Management to make estimates and assumptions that affect the amounts
         reported in the financial statements and accompanying notes. Actual
         results could differ from these estimates.
 
      c. Business Combinations: Business combinations which have been accounted
         for under the pooling of interests method of accounting requires the
         assets, liabilities, and shareholders' equity of the merged entity to
         be retroactively combined with the Corporation's respective accounts at
         recorded value. Prior period financial statements have been restated to
         give effect to business combinations accounted for under this method.
 
      d. Cash Equivalents: Cash equivalents include amounts due from banks and
         federal funds sold. Generally, federal funds are purchased and sold for
         periods of less than 30 days.
 
      e. Securities: Debt and equity securities are classified as
         held-to-maturity, available-for-sale, or trading. Securities classified
         as held-to-maturity are measured at amortized or historical cost,
         securities available-for-sale and trading at fair value. Adjustments to
         fair value of the securities available-for-sale, in the form of
         unrealized holding gains and losses, are excluded from earnings and
         reported net of tax as a separate component of shareholders' equity.
         Adjustments to fair value of securities classified as trading are
         included in earnings. Management determines the appropriate
         classification of debt securities at the time of purchase and
         re-evaluates such designation as of each balance sheet date. Debt
         securities are classified as held-to-maturity when the Corporation has
         the positive intent and ability to hold the securities to maturity.
         Classifying securities as available-for-sale allows the Corporation to
         sell securities to fund liquidity and manage the Corporation's interest
         rate risk. The Corporation does not maintain a trading account.
         Securities previously classified as held-to-maturity by Trumbull were
         reclassified to available-for-sale at the consummation of the
         transaction.
 
         The amortized cost of the debt securities classified as
         held-to-maturity or available-for-sale is adjusted for amortization of
         premiums and accretion of discounts to maturity or, in the case of
         mortgage-backed securities, over the estimated life of the security.
         Such amortization is included in interest income from
 
                                       30
<PAGE>   32
                      SECOND BANCORP, INC. AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
         investments. Interest and dividends are included in interest income
         from investments. Realized gains and losses, and declines in value
         judged to be other than temporary, are included in net securities gains
         (losses). The cost of securities sold is based on the specific
         identification method.
 
      f. Revenue Recognition: Interest on loans is accrued and credited to
         operations based upon the principal amount outstanding. Premiums on
         acquired loans have been deducted from the related interest income and
         are amortized over the remaining useful life of the loans acquired.
         Discounts and premiums on acquired deposits have been deducted or added
         respectively from the related interest expense and are being accreted
         or amortized over the remaining useful life of the deposits. The
         accrual of interest income generally is discontinued when a loan
         becomes, in Management's opinion, doubtful of being collectible. When
         interest accruals are discontinued, interest credited to income for the
         current year is reversed, and interest accrued in prior years is
         charged to the reserve for loan losses.
 
         The Corporation accounts for loan origination and commitment fees and
         certain direct loan origination costs by deferring the net fees, or net
         costs, and amortizing them as an adjustment of the related loan's
         yield. The Corporation is amortizing these amounts over the contractual
         life of the related loans. Net unamortized deferred costs, primarily
         representing costs of acquiring indirect automobile loans, were $2,055
         and $2,231 at December 31, 1998 and 1997, respectively.
 
      g. Loans Available-for-Sale: From time to time, the Corporation will sell
         loans it originated, mostly mortgages. The loans are reclassified as
         available-for-sale and are recorded at the aggregate cost or market
         value by loan.
 
      h. Reserve for Loan Losses: The reserve for loan losses is maintained at a
         level believed adequate by Management to absorb potential losses in the
         loan portfolio. Management's determination of the adequacy of the
         reserve is based upon an evaluation of the collectibility of the loans.
         These evaluations take into consideration such factors as changes in
         the nature and volume of the loan portfolio, current economic
         conditions that may affect the borrower's ability to pay, overall
         quality, and a review of specific problem loans. Certain loans are
         accounted for under SFAS No. 114, "Accounting by Creditors for
         Impairment of a Loan," as amended by SFAS No. 118, "Accounting by
         Creditors for Impairment of a Loan -Income Recognition and
         Disclosures." These standards address the accounting for certain loans
         when it is probable that amounts due pursuant to the contractual terms
         of the loan will not be collected. This evaluation is inherently
         subjective and requires Management to make estimates regarding the
         amounts and timing of future cash flows expected to be received on
         impaired loans that could be susceptible to change. To determine the
         amount of impaired loans, the Corporation analyzes the expected cash
         flows of non-accrual loans. To the extent that the net present value of
         expected cash flows is less than the carrying amount of an individual
         loan, the loan balance is included as impaired loans.
 
      i. Premises and Equipment: Premises and equipment are stated at cost, less
         accumulated depreciation and amortization. The provision for
         depreciation and amortization is computed generally by the
         straight-line method. Leasehold improvements are amortized over the
         shorter of the terms of the respective leases or the estimated useful
         lives.
 
      j. Intangible Assets: Intangible assets resulting from the excess of the
         purchase price over net identifiable tangible assets acquired through
         acquisitions are specifically identified when determinable. The excess
         goodwill is amortized based on the estimated useful life of the
         long-term assets acquired and on an accelerated basis. The core deposit
         intangible is amortized both on an accelerated basis and on a straight-
         line basis over the estimated useful life. Original estimated useful
         lives for the core deposit intangible and goodwill range from 10 to 14
         years and 8 to 22 years, respectively. Accumulated amortization as of
         December 31, 1998 and 1997 were $8,716 and $7,878, respectively.
 
      k. Mortgage Servicing Rights: The Corporation recognizes as separate
         assets the value of mortgage servicing rights, whether those rights are
         acquired through loan origination activities or through purchase
 
                                       31

                      SECOND BANCORP, INC. AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
         activities. Management stratifies servicing rights based on term or
         method of acquisition. Capitalized mortgage servicing rights are
         amortized on an accelerated basis over the estimated life of the loans
         sold. Management evaluates the recoverability of the mortgage servicing
         rights in relation to the impact of actual and anticipated loan
         portfolio prepayments, foreclosures, and delinquency experience.
 
      l. Interest Rate Risk Management: As part of managing the Corporation's
         interest rate risk, a variety of financial instruments may from time to
         time be used to hedge market values and to alter the cash flow
         characteristics of certain on-balance sheet instruments. The derivative
         financial instruments used primarily consist of interest rate caps and
         swaps. The derivative instruments used to manage interest rate risk are
         linked with a specific asset or liability or a group of related assets
         or liabilities at the inception of the derivative contract and have a
         high degree of correlation with the associated balance sheet item
         during the hedge period. Net interest income or expense on derivative
         contracts used for interest rate risk management is accrued. Deferred
         amounts are amortized into interest income or expense over either the
         remaining original life of the derivative instrument or the expected
         life of the associated asset or liability. Unrealized gains or losses
         are not recognized on the balance sheet.
 
     m. Federal Income Taxes: Deferred federal income taxes are provided for
        differences between tax and financial statement bases of assets and
        liabilities at year-end. Deferred taxes are recognized using the
        liability method, whereby tax rates are applied to cumulative temporary
        differences based on when and how they are expected to affect the tax
        return. Deferred tax assets and liabilities are adjusted for tax rate
        changes.
 
      n. Per Share Data: In 1997, the FASB issued SFAS No. 128, "Earnings per
         Share." Statement 128 replaced the calculation of primary and fully
         diluted earnings per share with basic and diluted earnings per share.
         Unlike primary earnings per share, basic earnings per share excludes
         any dilutive effects of options, warrants, and convertible securities.
         Diluted earnings per share is very similar to the previously reported
         fully diluted earnings per share. All earnings per share amounts for
         all periods have been presented, and where appropriate, restated to
         conform to the Statement 128 requirements. The Corporation had a
         two-for-one stock split on May 1, 1997 and a three-for-two stock split
         on May 1, 1995. All of the share and per share data have been restated
         to reflect these stock splits.
 
2.  RECENT ACCOUNTING PRONOUNCEMENTS
 
     a. Accounting for Transfers and Servicing of Financial Assets and
        Extinguishments of Liabilities: Certain provisions of SFAS No. 125,
        "Accounting for Transfers and Servicing of Financial Assets and
        Extinguishments of Liabilities," relating to repurchase agreements,
        securities lending and other similar transactions, and pledged
        collateral were deferred a year by SFAS No. 127, and were adopted
        prospectively as of January 1, 1998. The Statement provides consistent
        standards for distinguishing transfers of financial assets that are
        sales from transfers that are secured borrowings based on a control-
        oriented "financing-components" approach. Under this approach, after a
        transfer of financial assets, an entity recognizes the financial and
        servicing assets it controls and liabilities it has incurred,
        derecognizes financial assets when control has been surrendered, and
        derecognizes liabilities when extinguished. The adoption of these
        provisions did not have a material impact on financial position or
        results of operations.
 
     b. Reporting Comprehensive Income: In June 1997, the FASB issued SFAS No.
        130, "Reporting Comprehensive Income." This statement establishes
        standards for reporting the components of comprehensive income and
        requires that all items that are required to be recognized under
        accounting standards as components of comprehensive income be included
        in a financial statement that is displayed with the same prominence as
        other financial statements. Comprehensive income includes net income as
        well as certain items that are reported directly within a separate
        component of stockholders' equity and bypass net income. The Corporation
        adopted the provisions of this statement in 1998. These disclosure
        requirements had no impact on financial position or results of
        operations.
                                       32

                      SECOND BANCORP, INC. AND SUBSIDIARY
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     c. Disclosures about Segments of an Enterprise and Related Information: In
        June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of
        an Enterprise and Related Information." The provisions of the statement
        require disclosure of financial and descriptive information about an
        enterprise's operating segments in annual and interim financial reports
        issued to shareholders. The statement defines an operating segment as a
        component of an enterprise that engages in business activities that
        generate revenue and incur expense, whose operating results are reviewed
        by the chief operating decision maker in the determination of resource
        allocation and performance, and for which discrete financial information
        is available. The Corporation is deemed to have only one segment and,
        therefore, adoption of this statement had no impact on financial
        position or results of operation.
 
     d. Accounting for Derivative Instruments and Hedging Activities: In June
        1998, the FASB issued SFAS No. 133, "Accounting for Derivative
        Instruments and Hedging Activities." The provisions of this statement
        require that derivative instruments be carried at fair value on the
        balance sheet. The statement continues to allow derivative instruments
        to be used to hedge various risks and sets forth specific criteria to be
        used to determine when hedge accounting can be used. The statement also
        provides for offsetting changes in fair value or cash flows of both the
        derivative and the hedged asset or liability to be recognized in
        earnings in the same period; however, any changes in fair value or cash
        flows that represent the ineffective portion of a hedge are required to
        be recognized in earnings and cannot be deferred. For derivative
        instruments not accounted for as hedges, changes in fair value are
        required to be recognized in earnings.
 
        The provisions of this statement become effective for quarterly and
        annual reporting beginning January 1, 2000. Although the statement
        allows for early adoption in any quarterly period after June 30, 1998,
        the Corporation has no plans to adopt the provisions of SFAS No. 133
        prior to the effective date. The impact of adopting the provisions of
        this statement on the Corporation's financial position, results of
        operations and cash flow subsequent to the effective date is not
        currently estimable and will depend on the financial position of the
        Corporation and the nature and purpose of the derivative instruments in
        use by Management at that time.
 
3.  MERGERS AND ACQUISITIONS
 
     On August 20, 1998, Second Bancorp acquired Enfin, Inc. (Enfin), a $44
million asset bank holding company headquartered in Solon, Ohio, in a
transaction accounted for as a pooling of interests. Second Bancorp issued .5
million shares of common stock to the shareholders of Enfin, based upon an
exchange ratio of .95 shares of Second Bancorp common stock for each outstanding
share of Enfin common stock. The historical consolidated financial statements
have been restated to reflect this transaction.
 
     On November 19, 1998, Second Bancorp acquired Trumbull Financial
Corporation (Trumbull), a $462 million asset unitary thrift holding company
headquartered in Warren, Ohio, in a transaction accounted for as a pooling of
interests. Second Bancorp issued 3.3 million shares of common stock to the
shareholders of Trumbull based upon an exchange ratio of 3.78 shares of Second
Bancorp common stock for each outstanding share of Trumbull common stock. The
historical consolidated financial statements have been restated to reflect this
transaction.
 
     Prior to the merger, Trumbull used a fiscal year end of September 30. The
1998 financial statements combine each company's year ended December 31. The
restated financial statements for the years ended December 31, 1997 and 1996
combine Second Bancorp's and Enfin's financial statements for the years ended
December 31, 1997 and 1996 with Trumbull's financial statements for the years
ended September 30, 1997 and 1996, respectively. Due to the different fiscal
year ends, Trumbull's results for the three months ended December 31, 1997 are
reflected as an adjustment in the accompanying statement of shareholders'
equity. Net income for Trumbull for the period totaled $915, with dividends
declared of $269 and a net change in unrealized gains on securities
available-for-sale of $19.

     Conforming adjustments for the pooled company for the fiscal quarter ending
December 31, 1997 included recoveries of $5, charge-offs of $54, and provision
for loan losses of $60.
 
  Non-accrual, past-due and restructured loans (non-performing loans):
 
     Non-accrual loans are loans that are no longer accruing interest at the
discretion of Management. This occurs when Management determines that the
borrower can no longer service the debt, but the loan is adequately secured with
collateral or the borrower is able to repay the principal portion of the loan in
the future. Past-due loans are loans with principal payments more than 90 days
past due. Both interest and principal are expected to be repaid. Restructured
loans include loans whose original terms were redesigned to allow the customer
to remain current and repay the loan. Also listed is other real estate owned
which represents real estate acquired through the default of loans. The Bank's
practice is to carry other real estate owned at the lower of cost or fair market
value, less estimated costs to sell.

     During 1997, the obligations of one of the Bank's borrowers were included
in non-performing loans as of December 31, 1996 and the first three quarters of
1997, and were settled with the Bank by the placement of approximately $2.7
million into a third party trust. The Bank reclassified the remaining loan
balance of $2.4 million to other assets as of December 31, 1997 and the amount
was substantially collected in 1998.
 
     For the year ended December 31, 1998, interest income that would have been
earned under the original terms of the loans classified in non-accrual and
restructured loans in the above schedule amounted to $494. No interest income
was realized on these loans for 1998. Loans that were considered to be impaired
under SFAS No. 114 totaled $2,367 and $1,864 as of December 31, 1998 and 1997,
respectively, all of which were included in non-performing assets as of those
dates. The related allowance allocated to impaired loans for 1998 and 1997 was
$340 and $1,187, respectively.
 
8.  FAIR VALUES OF FINANCIAL INSTRUMENTS
 
     SFAS No. 107, "Disclosures about Fair Value of Financial Instruments,"
requires that the Corporation disclose estimated fair values for its financial
instruments. The market value of securities, as presented in Note 5, is based
primarily upon quoted market prices. For substantially all other financial
instruments, the fair values are Management's estimates of the values at which
the instruments could be exchanged in a transaction between willing parties. In
accordance with SFAS No. 107, fair values are based on estimates using present
value and other valuation techniques in instances where quoted prices are not
available. These techniques are significantly affected by the assumptions used,
including discount rates and estimates of future cash flows. As such, the
derived fair value estimates cannot be substantiated by comparison to
independent markets and, further, may not be realizable in an immediate
settlement of the instruments. SFAS No. 107 also excludes certain items from its
disclosure requirements. Accordingly, the aggregate fair value amounts presented
do not represent, and should not be construed to represent, the underlying value
of the Corporation.

     Fair value estimates, methods, and assumptions are set forth below for the
Corporation's financial instruments:
 
     Cash and cash equivalents: The carrying amounts reported in the balance
sheet for cash and cash equivalents approximate those assets' fair value.
 
     Securities: Fair values for securities are based on quoted market prices,
where available. If quoted market prices are not available, fair values are
based on quoted market prices of comparable instruments.
 
     Loans: Variable-rate loans that reprice frequently are assumed to have a
short-duration period, yielding a fair value that approximates the carrying
value. The fair values for other loans are estimated using a discounted cash
flow calculation.
 
     Cost of mortgage servicing rights: The fair value for the cost of mortgage
servicing rights as of December 31, 1998 were determined via an independent
quote from a third party. The fair values as of December 31, 1997 were
established using discounted cash flows. Included in the valuation of fair value
were assumptions regarding prepayment speeds, discount rates, servicing costs,
delinquency, ancillary income, and foreclosure costs which were arrived at from
third party sources and internal historical records.
 
     Deposit liabilities: The fair values disclosed for demand deposits, insured
money market and interest checking accounts, and savings accounts are, by
definition, equal to the amount payable on demand at the reporting date (i.e.,
their carrying amounts). The carrying amounts for time deposits are estimated
using a discounted cash flow calculation. Variable-rate time deposits that
reprice frequently are assumed to have a short-duration period, yielding a fair
value that approximates the carrying value.

     Federal funds purchased, securities sold under agreements to repurchase,
and other short-term borrowings: The carrying amounts of federal funds
purchased, securities sold under agreements to repurchase, and other short-term
borrowings approximate their fair values.
 
     As of December 31, 1997, the Corporation had no outstanding off-balance
sheet instruments requiring fair value disclosure.

10.  FEDERAL FUNDS PURCHASED AND SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE
 
     The Corporation has available to it the ability to borrow in excess of $37
million from correspondent banks as overnight federal funds purchased. There
were no federal funds purchased at December 31, 1998, 1997, or 1996. The
Corporation has repurchase agreements with corporate customers and local
municipalities. These borrowings have an overnight maturity and are
collateralized with U. S. Treasury and government agency securities, including
agency-issued mortgage-backed securities with a market value of $101,832 and
$127,496 as of December 31, 1998 and 1997, respectively. The securities are held
in the Corporation's safekeeping account at the Federal Reserve Bank. The
Corporation also maintains repurchase agreements with approved brokers and are
collateralized by U. S. Treasury and government agency securities held by the
broker. The following table summarizes certain information relative to these
borrowings:

     As of December 31, 1998, the Corporation has available a total of $15
million in unsecured lines of credit with two correspondent banks. The lines are
renewable annually and bear interest at a floating rate based on several indices
including LIBOR, Federal funds, or prime rate.
 
12.  SHAREHOLDERS' EQUITY
 
     On June 25 and July 7, 1993, the Corporation issued a total of 718,750
shares of $1.50 Cumulative Convertible Preferred Stock, Series A-1 (the
"preferred stock"), generating net proceeds of $13,235,000. During 1995 and
1996, the majority of holders converted their shares of preferred stock to
common stock at a rate of 2.2354 shares of common stock for each share of
preferred stock. A nominal number of shares were redeemed for cash.
 
     Dividends are paid by the Corporation from its assets, which are mainly
provided by dividends from the Bank. However, certain restrictions exist
regarding the ability of the Bank to transfer funds to the Corporation in the
form of cash dividends, loans, or advances. The approval of the Comptroller of
the Currency is required to pay dividends in excess of the Bank's earnings
retained in the current year plus retained net profits from the preceding two
years. As of December 31, 1998, the Bank had retained earnings of $78,958, of
which $8,573 was available for distribution to the Corporation as dividends
without prior regulatory approval.
 
     On February 27, 1998, the Board of Directors rescinded the authorization to
repurchase any shares of common stock. As of December 31, 1998, the Corporation
had 50,400 shares held in treasury.
 
     The Corporation and the Bank are subject to various regulatory capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can initiate certain mandatory, and possibly
additional discretionary, actions by regulators that, if undertaken, could have
a direct material effect on the Corporation's and the Bank's financial
statements. Under capital adequacy guidelines and the regulatory framework for
prompt corrective action, the Corporation and the Bank must meet specific
capital guidelines that involve quantitative measures of the Bank's assets,
liabilities, and certain off-balance sheet items as calculated under regulatory
accounting practices. The Corporation's and the Bank's capital amounts and
classification are also subject to qualitative judgments by the regulators about
components, risk weightings, and other factors.
 
     Quantitative measures established by regulation to ensure capital adequacy
require the Corporation and the Bank to maintain minimum amounts and ratios (set
forth in the table below) of Total and Tier I capital (as defined
                                       41

by the regulations) to risk-weighted assets (as defined), and of Tier I capital
(as defined) to average assets (as defined). Management believes, as of December
31, 1998, that the Corporation and the Bank meet all capital adequacy
requirements to which it is subject.
 
     As of December 31, 1998, the most recent notification from the Office of
the Comptroller of the Currency categorized the Bank as well capitalized under
the regulatory framework for prompt corrective action. To be categorized as well
capitalized, the Bank must maintain minimum Total risk-based, Tier I risk-based,
and Tier I leverage ratios as set forth in the table. There are no conditions or
events since that notification that Management believes have changed the Bank's
category.
 
     The consolidated Corporation's and the subsidiary Bank's actual capital
amounts and ratios are also presented in the table.

15. EMPLOYEE BENEFIT PLANS
 
     The Corporation has a non-contributory, defined-benefit pension plan
covering substantially all of its employees. The benefits are based on a
percentage of the employee's average annual earnings multiplied by completed
years of continuous service. The Corporation's funding policy is to contribute
annually an amount between the minimum required and the maximum amount that can
be deducted for federal income tax purposes. Contributions are intended to
provide not only for benefits attributed to service to date but also for those
expected to be earned in the future. The plan assets at December 31, 1998 are
invested primarily in common stock, preferred stock, and corporate bonds. The
Bank also has a supplemental retirement deferred benefit plan for certain
employees, which provides benefits in excess of the defined benefit plan.

     Prior to its acquisition, Trumbull had a noncontributory defined benefit
retirement plan covering substantially all of its employees. The plan was a
multi-employer plan and separate actuarial valuations were not made with respect
to each employer, nor were plan assets so segregated. The multi-employer plan
still covers the benefit obligation for the former Trumbull employees who are
now employed by the Corporation. Amounts contributed to the plan were $0, $71,
and $79 in 1998, 1997, and 1996, respectively.
 
     The Bank also has a stock appreciation rights plan that was used to grant
certain officers stock appreciation rights upon their employ. The Corporation
has not issued any rights since 1987. As of December 31, 1998 and 1997, the
accumulated obligation for these rights recorded in the financial statements was
$168 and $394, respectively. The plan expense for 1998, 1997, and 1996 was $56,
$190, and $9, respectively.
 
     The Bank also sponsors a defined contribution benefit plan covering
substantially all eligible employees of the Bank. The Bank voluntarily
contributes 75% of the participants' contribution to a maximum of 4.5% of the
participant's compensation. Participants, at their discretion, may invest in
several investment funds or a stock fund consisting solely of the Corporation's
common stock. The Bank's contribution is limited solely to the stock fund.
Contributions in 1998, 1997, and 1996 were $410, $395, and $360, respectively.
The Board of Directors of the Corporation has authorized the issuance of 99,000
shares of the Corporation's common stock for use in the Bank's defined
contribution benefit plan. As of December 31, 1998, none of the shares
authorized have been issued.
 
16.  STOCK OPTIONS
 
     The Corporation maintains incentive and non-qualified stock option plans
that allow for stock based awards to eligible employees and directors. Through
February 1998, the Corporation issued incentive stock options that were
exercisable in one year after issuance and expire after 10 years. The maximum
annual grant was 7,500 shares per employee. The plan was terminated in May 1998
when the non-qualified stock option plan was approved. The non-qualified plan
authorizes 650,000 shares of common stock to be reserved and subject to
issuance. The maximum annual grant is 10,000 shares per employee and 1,000
shares per director. The options are also exercisable one year after issuance
and expire after 10 years.
 
     Pro forma information regarding net income and earnings per share is
required by SFAS No. 123, "Accounting for Stock-Based Compensation" and has been
determined as if the Corporation had accounted for its employee stock options
under the fair-value method of that Statement. Under the fair-value based
method, compensation cost is measured at the grant date based upon the value of
the award and recognized over the service period. The Corporation has elected,
as the standard allows, to continue to measure compensation costs for its plans
as prescribed in Accounting Principles Board (APB) Opinion No. 25, "Accounting
for Stock Issued to Employees" because the alternative fair value accounting
provided under SFAS No. 123 requires use of option valuation models that were
not developed for use in valuing employee stock options. Under APB No. 25,
because the exercise price of the Corporation's employee stock options equals
the market price of the underlying stock on the date of grant, no compensation
expense is recognized. Pro forma disclosure of net income and earnings per share
is made in the accompanying footnotes as if the fair-value method of accounting,
as defined by SFAS No. 123, had been adopted.

     The fair value for these options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted-average
assumptions:
 
<TABLE>

Weighted-average expected life....................  6 years    6 years    6 years
</TABLE>
 
     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Corporation's employee stock options have
characteristics significantly different from those of traded options, and
because changes in the subjective input assumptions can materially affect the
fair value estimate, in Management's opinion, the existing models do not
necessarily provide a reliable single measure of the fair value of its employee
stock options.
 
     For purposes of the pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The
Corporation's pro forma information follows:

18.  OFF-BALANCE SHEET INSTRUMENTS
 
     The Corporation utilizes off-balance sheet financial instruments,
frequently called interest rate derivatives, to efficiently manage its exposure
to interest rate risk. As with any financial instrument, derivatives have
inherent risks. Market risk includes the risk of gains and losses that result
from changes in interest rates. These gains and losses may be offset by other
on- or off-balance sheet transactions. Credit risk is the risk that the
counter-party fails to perform according to the terms of the contract. Credit
risk can be measured as the cost of acquiring a new derivative contract with
identical cash flows as those of the defaulted agreement.
 
     The Corporation uses interest rate cap contracts to help protect its net
interest margin in periods of extremely high interest rates. As of December 31,
1998, the Corporation's interest rate cap contracts used for interest rate risk
management purposes had a notional amount of $30,900, unrealized loss of $228,
an average strike rate of 6.0%, and an average life of 3.3 years.

19.  COMMITMENTS AND CONTINGENT LIABILITIES
 
  Loan Commitments:
 
     Loan commitments are made to accommodate the financial needs of the Bank's
customers; however, there are no long-term, fixed-rate loan commitments that
result in market risk. Standby letters of credit commit the Bank to make
payments on behalf of customers when certain specified future events occur. They
primarily are issued to facilitate customers' trade transactions.
 
     Both arrangements have credit risk, essentially the same as that involved
in extending loans to customers, and are subject to the Bank's normal credit
policies. Collateral (e.g., securities, receivables, inventory, and equipment)
is obtained based on Management's credit assessment of the customer.
 
     The Bank's maximum obligation to extend credit for loan commitments
(unfunded loans and unused lines of credit) and standby letters of credit
outstanding on December 31 was as follows:

  Lease Agreements:
 
     The Bank has entered into lease agreements covering its main office,
several branch locations, and equipment for various periods through 2011, with
options to renew. Also, the Bank has the option to purchase the main office
facility before two optional renewal periods at the fair market value in
existence at that time.
 
     Future minimum commitments under non-cancelable operating leases are as
follows:

     Rentals under operating leases and data processing costs amounted to
$3,501, $2,762, and $3,163 in 1998, 1997, and 1996, respectively.
 
     Low Income Housing Project: In 1993, the Bank began investing in low-income
housing tax credit projects designed to provide affordable housing for Ohio
communities. The Bank has invested $1,061 to date and has begun to realize tax
credits and tax savings from the investments. The Bank is committed to invest

     Most of the Bank's business activity is with customers located within the
state of Ohio. As of December 31, 1998, the Bank had a concentration in
commercial real estate loans totaling approximately $258,000, approximately
68.5% of which were owner-occupied businesses, including medical office
buildings, retail, and fast-food restaurants within the Bank's market area. Of
the $258,000 of commercial real estate loans, $3,453 or 1.3% were on non-accrual
status as of December 31, 1998.

                      SECOND BANCORP, INC. AND SUBSIDIARY
 
                         REPORT OF INDEPENDENT AUDITORS
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF SECOND BANCORP, INC.
 
     We have audited the accompanying consolidated balance sheets of Second
Bancorp, Inc. and subsidiary as of December 31, 1998 and 1997, and the related
consolidated statements of income, shareholders' equity, and cash flows for each
of the three years in the period ended December 31, 1998. These financial
statements are the responsibility of the Corporation's Management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with 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 of 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 audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Second Bancorp,
Inc. and subsidiary at December 31, 1998 and 1997, and the consolidated results
of their operations and their cash flows for each of the three years in the
period ended December 31, 1998, in conformity with generally accepted accounting
principles.

     AMENDMENTS DATED MARCH 17, 1987; JANUARY 7, 1991; JUNE 20, 1997; SEPTEMBER
     18, 1998; AND NOVEMBER 10, 1998)
 
                          ARTICLES OF INCORPORATION OF
                          SECOND BANCORP, INCORPORATED
 
     The undersigned, acting as the incorporator of a corporation for profit
under the general corporation laws of the State of Ohio, adopts the following
Articles of Incorporation:
 
     FIRST: The name of the Corporation shall be Second Bancorp Incorporated.
 
     SECOND: The place in Ohio where its principal office is to be located is at
108 Main Avenue S.W., in the City of Warren, Trumbull County, Ohio, but the
Corporation may establish and maintain its principal office, or other offices,
at other places in the United States of America, as its Board of Directors may
from time to time determine.
 
     THIRD: The purpose for which the Corporation is formed is to engage in
business as a "bank holding company" in accordance with, and to the extent
permitted by, the Bank Holding Company Act of 1956 (Pub. Law 511, 84th Cong. 2d
Sess., approved May 9th, 1956) as amended, and consistent therewith to engage in
any other lawful act or activity for which corporations may be formed under
Chapter 1701 of the Ohio Revised Code, to the extent that such act or activity
is not then prohibited by the Bank Holding Company Act of 1956, as amended. The
Corporation may from time to time, pursuant to authorization by the Board of
Directors and without action by the shareholders, purchase or otherwise acquire
shares of the Corporation of any class or classes in such manner, upon such
terms and in such amounts as the Board of Directors shall determine; subject,
however, to such limitation or restriction, if any, as is contained in the
express terms of any class of shares of the Corporation outstanding at the time
of the purchase or acquisition in question.
 
     FOURTH: The maximum number of capital shares which this Corporation is
authorized to issue or to have outstanding at any time shall be twenty million
(20,000,000) shares, all of which shall be common shares. The shares will have
no par value stated. The Board of directors of the Corporation is hereby
empowered to issue from time to time shares of its capital shares, whether now
or hereafter authorized. No holders of any class of shares of the Corporation
shall have any preemptive rights to purchase or to have offered to them for
purchase any shares or other securities of the Corporation.
 
     FIFTH: The amount of stated capital with which this Corporation will begin
business shall be five hundred dollars ($500.00).
 
     SIXTH: (A) The number of directors constituting the Board of Directors
shall be such number, not more than eighteen (18), as shall be fixed from time
to time in accordance with the Regulations of the Corporation and the number so
fixed shall constitute the Board of Directors until the number of directors is
thereafter changed pursuant to the provisions of the Regulations, but the number
thereof shall in no event be less than six (6) and the number of directors in
each class shall in no event be less than three (3).
 
          (B) The Board of Directors shall be and is divided into two classes,
     Class I and Class II, which shall be as nearly equal in number as possible.
     Each director shall serve for a term ending on the date of the second
     annual meeting following the annual meeting at which such director was
     elected, provided, however, that each initial director in Class I shall
     hold office until the annual meeting of shareholders in 1987; and each
     initial director in Class II shall hold office until the annual meeting of
     shareholders in 1988.
 
          (C) In the event of any increase or decrease in the authorized number
     of directors, (i) each director then serving as such shall nevertheless
     continue as a director of the class of which he or she is a member until
     the expiration of his or her current term, or his or her prior death,
     retirement, resignation or removal and (ii) the newly created or eliminated
     directorship resulting from such increase or decrease shall be apportioned
     by the Board of Directors among the two classes of directors so as to
     maintain such classes as nearly equal as possible.

          (D) Notwithstanding any of the foregoing provisions of this Article
     SIXTH, each director shall serve until his or her successor is elected and
     qualified or until his or her death, retirement, resignation, or removal.
     Should a vacancy occur or be created, whether arising through death,
     resignation or removal of a director, or through an increase in the number
     of directors of any class, such vacancy shall be filled by a majority vote
     of the remaining directors of the class in which such vacancy occurs, or by
     the sole remaining director of the class if only one such director remains,
     or by the majority vote of the remaining directors of the other class if
     there be no remaining member of the class in which the vacancy occurs. A
     director so elected to fill a vacancy shall serve for the remainder of the
     then present term of office of the class to which he or she was elected.
 
          (E) Wherever the term "Board of Directors" is used in these Articles
     of Incorporation, such terms shall mean the Board of Directors of the
     Corporation; provided, however, that, to the extent any committee of
     directors of the Corporation is lawfully entitled to exercise the powers of
     the Board of Directors, such committee, to the extent provided by
     resolution of the Board of Directors or the Regulations, may exercise any
     power or authority of the Board of Directors under these Articles of
     Incorporation in management of the business and affairs of the Corporation,
     including without limitation, the declaration of a dividend or the
     authorization of the issuance of shares.
 
     SEVENTH: Each person who is or was a director, officer, employee or agent
of the Corporation shall be indemnified by the Corporation to the full extent
permitted by the corporation laws of the State of Ohio, now or hereafter in
force, against any liability, cost or expense incurred by him in his capacity as
a director, officer, employee, or agent, or arising out of his status as a
director, officer, employee, or agent. The corporation may, but shall not be
obligated to maintain insurance at its expense, to protect itself and any such
person against any such liability cost or expense. The rights of indemnification
provided in this Article SEVENTH shall be in addition to any rights to which any
person concerned may otherwise be entitled by the Regulations of the Corporation
from time to time in effect, by contract or as a matter of law, and shall inure
to the benefit of the heirs, executors and administrators of any such person.
 
     EIGHTH: (1) A. In addition to any affirmative vote required by law:
 
             (i) any merger or consolidation of the Corporation or any
        Subsidiary (as hereinafter defined) with (a) any Related Person (as
        hereinafter defined) or (b) any other corporation (whether or not itself
        a Related Person) which is, or after such merger or consolidation would
        be, an Affiliate (as hereinafter defined) of a Related Person; or
 
             (ii) any sale, lease, exchange, mortgage, pledge, transfer or other
        disposition (in one transaction of a series of transactions) to or with
        any Related Person or any Affiliate of any Related Person of any assets
        of the Corporation or any Subsidiary having an aggregate Fair Market
        Value (as hereinafter defined) equal to 10% or more of the consolidated
        net worth of the Corporation; or
 
             (iii) the issuance or transfer by the Corporation or any Subsidiary
        (in one transaction or a series of transactions) of any securities of
        the Corporation or any Subsidiary to any Related Person or any Affiliate
        of any Related Person in exchange for cash, securities or other property
        (or a combination thereof) having an aggregate Fair Market Value equal
        to 10% or more of the consolidated net worth of the Corporation; or
 
             (iv) the adoption of any plan or proposal for the liquidation or
        dissolution of the Corporation; or
 
             (v) any reclassification of securities (including any reverse share
        split), or recapitalization of the Corporation, or any merger or
        consolidation of the Corporation with any of its Subsidiaries or any
        other transaction (whether or not with or into or otherwise involving a
        Related Person) which has the effect, directly or indirectly, of
        increasing the proportionate share of the outstanding shares of any
        class of Equity Security (as hereinafter defined) of the Corporation or
        any Subsidiary which is directly or indirectly owned by any Related
        Person or any Affiliate of any Related Person, shall require the
        affirmative vote of the holders of at least 75% of the voting power of
        the then outstanding shares of capital shares of the Corporation
        entitled to vote generally in the election of directors. Such
        affirmative
 
                                       59
<PAGE>   61
 
        vote shall be required notwithstanding the fact that no vote may be
        required or that a lesser percentage may be specified, by law or
        otherwise.
 
             B. The term "Business Combination" used in this Article EIGHTH
        shall mean any transaction which is referred to in any one or more of
        clauses (i) through (v) of paragraph A of this Section.
 
     (2) Notwithstanding the requirements of the previous Section, no Business
Combination between the Corporation (or any Subsidiary) and a Related Person or
any Affiliate of a Related Person may be effected unless all of the following
conditions are met:
 
          A. The aggregate amount of the cash and the Fair Market Value as of
     the date of the consummation of the Business Combination of consideration
     other than cash to be received per share by holders of any class of Equity
     Security in such Business Combination shall be at least equal to the
     highest per share price (including any brokerage commissions, transfer
     taxes and soliciting dealer's fees) paid by the Related Person for any
     shares of the same class of Equity Security previously acquired by it, plus
     interest on such amount compounded annually from the date that the Related
     Person became a Related Person (the "Determination Date") through the date
     of consummation of the Business Combination (the "Consummation Date") at
     the rate publicly announced as the "Prime Rate" of interest (announced by
     such major bank as may be selected by a majority of the Continuing
     Directors), from time to time in effect, less the aggregate amount of any
     cash dividends paid and the Fair Market Value of any dividends paid in
     other than cash on each share from the Determination Date through the
     Consummation Date, up to, but not exceeding, the amount of interest payable
     per share.
 
          B. The consideration to be received by holders of a particular class
     of Equity Security shall, except to the extent a shareholder agrees
     otherwise, be in cash or in the same form as the Related Person has
     previously paid for shares of such class of Equity Security. If the Related
     Person has paid for shares of any class of Equity Security with varying
     forms of consideration, the form of consideration for such class of Equity
     Security shall be either cash or in the form used to acquire the largest
     number of shares of such class of Equity Security previously acquired by
     it. The price determined in accordance with paragraph A of this Section
     shall be subject to appropriate adjustment in the event of any share
     dividend, share split, combination of shares or similar event.
 
     (3) The provisions of Sections (1) and (2) of this Article EIGHTH shall not
apply to a Business Combination if:
 
          A. The Continuing Directors of the Corporation by a two-thirds vote
     (i) have expressly approved a memorandum of understanding with the Related
     Person with respect to the Business Combination prior to the time that the
     Related Person became a Related Person and the Business Combination is
     effected on substantially the same terms and conditions as are provided by
     the memorandum of understanding, or (ii) have otherwise approved the
     Business Combination (this provision is incapable of satisfaction unless
     there is at least one Continuing Director); or
 
          B. The Business Combination is solely between the Corporation and
     another corporation, one hundred percent of the Voting Shares of which is
     owned directly or indirectly by the Corporation.
 
          In the event the Continuing Directors shall approve a Business
     Combination as set forth in paragraph A above, or the Business Combination
     is solely between the Corporation and another corporation described in
     paragraph B above, such Business Combination shall require only such
     shareholder vote, if any, as is required by law.
 
     (4) For the purpose of this Article EIGHTH:
 
          A. "Person" shall mean any individual, firm, corporation or other
     entity.
 
          B. "Related Person" shall mean any Person who or which:
 
             (i) is the beneficial owner, directly or indirectly, of 10% or more
        of the voting power of the outstanding Voting Shares; or
 
                                       60
<PAGE>   62
 
             (ii) is an Affiliate or Associate of the Corporation and at any
        time within the two-year period immediately prior to the date in
        question was the beneficial owner, directly or indirectly, of 10% or
        more of the voting power of the then outstanding Voting Shares; or
 
             (iii) is an assignee of or has otherwise succeeded to any shares of
        Voting Shares which were at any time within the two-year period
        immediately prior to the date in question beneficially owned by any
        Related Person, if such assignment or succession shall have occurred in
        the course of a transaction or series of transactions not involving a
        public offering within the meaning of the Securities Act of 1933, as
        amended.
 
          Provided, however, that the term "Related Person" shall not include
     (i) the Corporation or any Subsidiary, (ii) any one or any group of the
     Continuing Directors, or (iii) any profit-sharing, employee shares
     ownership or other employee benefit plan of the corporation or any
     Subsidiary of the Corporation or any trustee of or other fiduciary with
     respect to any such plan when acting in that capacity.
 
          C. A Person shall be a "beneficial owner" of any Voting Shares:
 
             (i) which such Person or any of its Affiliates or Associates (as
        hereinafter defined) beneficially owns, directly or indirectly; or
 
             (ii) which such Person or any of its Affiliates or Associates has
        (a) the right to acquire (whether such right is exercisable immediately
        or only after the passage of time) pursuant to any agreement,
        arrangement or understanding or upon the exercise of conversion rights,
        exchange rights, warrants or options, or otherwise, or (b) the right to
        vote pursuant to any agreement, arrangement or understanding; or
 
             (iii) which is beneficially owned, directly or indirectly, by any
        other Person with which such Person or any of its Affiliates or
        Associates has any agreement, arrangement or understanding for the
        purpose of acquiring, holding, voting or disposing of any shares of
        Voting Shares.
 
          D. For the purpose of determining whether a Person is a Related Person
     pursuant to paragraph B of this Section, the number of shares of Voting
     Shares deemed to be outstanding shall include shares deemed owned through
     application of paragraph C of this Section, but shall not include any other
     shares of Voting Shares which may be issuable pursuant to any agreement,
     arrangement or understanding, or upon exercise of conversion rights,
     warrants or options, or otherwise.
 
          E. "Affiliate" or "Associate" shall have the respective meanings
     ascribed to such terms in Rule 12b-2 of the General Rules and Regulations
     under the Securities Exchange Act of 1934, as in effect on January 1, 1986.
 
          F. "Subsidiary" means any corporation of which a majority of any class
     of Equity Security is owned, directly or indirectly, by the Corporation;
     provided, however, that for the purposes of the definition of Related
     Person set forth in paragraph B of this Section, the term "Subsidiary"
     shall mean only a corporation of which a majority of each class of Equity
     Security is owned, directly or indirectly, by the Corporation.
 
          G. "Continuing Director" means any member of the Board of Directors
     who is unaffiliated with the "Related Person" and was a member of the Board
     of Directors prior to the time that the Related Person became a Related
     Person, and any successor of a Continuing Director who is unaffiliated with
     the Related Person and is recommended to succeed a Continuing Director by
     two-thirds of the Continuing Directors then on the Board of Directors.
 
          H. "Fair Market Value" means: (i) in the case of stock, the highest
     closing sales price during the 30-day period immediately preceding the date
     in question of a share of such stock on the Composite Tape for New York
     Stock Exchange -- Listed Stocks, or, if such stock is not quoted on the
     composite Tape, on the New York Stock Exchange, or, if such stock is not
     listed on the Exchange, on the principal United States securities exchange
     registered under the Securities Exchange Act of 1934 on which such stock is
     listed, or, if such stock is not listed on any such exchange, the highest
     closing bid quotation with respect to a share of such stock during the
     30-day period preceding the date in question on the National Association of
     Securities

     Dealers, Inc. Automated Quotations Systems or any system then in use, or if
     no such quotations are available, the fair market value on the date in
     question of a share of such stock as determined by a two-thirds vote of the
     Continuing Directors; and (ii) in the case of property other than cash or
     stock, the fair market value of such property on the date in question as
     determined by a two-thirds vote of the Continuing Directors.
 
          I. In the event of any Business Combination in which the Corporation
     survives, the phrase "consideration other than cash to be received" as used
     in paragraph A of this Section shall include the shares of any class of
     Equity Security retained by the holders of such shares.
 
          J. "Equity Security" shall have the meaning ascribed to such term in
     Section 3(a)(11) of the Securities Exchange Act of 1934, as in effect on
     January 1, 1986.
 
          K. "Voting Shares" means shares of any Equity Security of a
     corporation which are entitled to vote in the election of Directors of such
     corporation.
 
          L. The phrase "series of related transactions" shall be deemed to
     include not only a series of transactions with the same Related Person but
     also a series of separate transactions with a Related Person or any
     Affiliate or Associate of such Related Person.
 
     (5) The Continuing Directors shall, by two-thirds vote, have the power and
duty to determine for the purposes of this Article EIGHTH on the basis of
information known to them after reasonable inquiry, (A) whether a Person is a
Related Person, (B) the number of shares of Voting Shares beneficially owned by
any Person, (C) whether a Person is an Affiliate or Associate of another, (D)
whether the assets which are the subject of any Business Combination have, or
the consideration to be received for the issuance or transfer of securities by
the Corporation or any Subsidiary in any Business Combination has, an aggregate
Fair Market Value equal to 10% or more of the consolidated net worth of the
corporation. The Continuing Directors shall, by two-thirds vote, have the
further power to interpret all other terms and provisions of this Article
EIGHTH.
 
     (6) Nothing contained in this Article EIGHTH shall be construed to relieve
any Related Person from any fiduciary obligation imposed by law.
 
     NINTH: Notwithstanding any statutory provision now or hereafter in force
requiring for any purpose the vote, consent, waiver or release of the holders of
shares entitling them to exercise two-thirds, or any other proportion, of the
voting power of the Corporation or of any class or classes of shares thereof,
such action, unless otherwise expressly required by statute or by these
Articles, may be taken by the vote, consent, waiver or release of the holders of
shares entitling them to exercise a majority of the voting power of the
Corporation or of such class or classes. Each of Articles SIXTH, SEVENTH and
EIGHTH and this Article NINTH, of these Articles of Incorporation may be amended
at any regular or special meeting of the shareholders only by the affirmative
vote of the holders of at least 75% of the voting power of the outstanding
shares of this Corporation.
 
     TENTH: Any and every statute of the State of Ohio hereafter enacted,
whereby the rights, powers or privileges of corporations or of the shareholders
of corporations organized under the laws of the State of Ohio are increased or
diminished or in any way affected, or whereby effect is given to the action
taken by any number, less than all, of the shareholders of any such corporation,
shall apply to the Corporation and shall be binding not only upon the
Corporation, but upon every shareholder of the Corporation to the same extent as
if such statute had been in force at the date of filing these Articles of
Incorporation of the Corporation in the office of the Secretary of State of
Ohio. The right to alter, amend, change or repeal any clause or provision of
these Articles of Incorporation, in the manner now or hereafter prescribed by
law, is hereby reserved to the Corporation; and all rights conferred on
officers, Directors and shareholders herein are granted subject to such
reservation.

10.15  FORM OF NON-QUALIFIED STOCK OPTION AGREEMENT.
 
                      NON-QUALIFIED STOCK OPTION AGREEMENT
 
                   FOR                ,                AWARD
 
                                  pursuant to
 
                          SECOND BANCORP INCORPORATED
                      1998 NON-QUALIFIED STOCK OPTION PLAN
 
     THIS NON-QUALIFIED STOCK OPTION AGREEMENT (the "Agreement") made and
entered into as of the                day of                ,                ,
between Second Bancorp Incorporated (the "Company") and                (the
"Optionee").
 
     WHEREAS, the Company having determined that its interests will be advanced
by (a) providing incentive to officers, key employees, and non-employee
directors of the Company and The Second National Bank of Warren (its
"Subsidiary") to stimulate their efforts toward the continued success of the
Company and its Subsidiary and to operate and manage the business in a manner
which will provide for the long-term growth and profitability of the Company and
its Subsidiary, (b) encouraging stock ownership by officers, key employees and
non-employee directors; and (c) providing a means of attracting, retaining and
rewarding key employees and non-employee directors; and
 
     WHEREAS, the Company and its shareholders have approved the Second Bancorp
Incorporated 1998 Non-Qualified Stock Option Plan (the "Plan") pursuant to which
the Company (a) grants stock options to the non-employee directors of the
Company and Subsidiary, and (b) may grant stock options to its officers and key
employees from time to time as determined in the sole discretion of the
Compensation and Organization Committee of the Board of Directors of the Company
(the "Committee");
 
     NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements hereinafter set forth, the Company and Optionee hereby
mutually covenant and agree as follows:
 
GRANT OF OPTIONS. Effective                ,                (the "Award Date"),
the Company hereby grants to the Optionee, as a matter of separate agreement and
not in lieu of salary, fee or other compensation for services, the right and
option to purchase                full shares of authorized but unissued common
stock of the Company on the terms and conditions herein set forth (the "Award").
Notwithstanding the foregoing, the Optionee understands and agrees that if, in
the sole determination of the Committee, the option Award prevents or in any way
adversely affects the Company's qualification for "pooling" treatment of any
acquisition, this Award may be withdrawn or adjusted by the Company in any
manner deemed necessary by the Committee to preserve that accounting treatment.
 
PRICE. The purchase price of said shares of common stock subject to the Award
shall be                Dollars ($          ) per share, the fair market value
of the common stock on the date of the grant pursuant to the Plan.
 
          3. EXERCISE OF OPTIONS. Except as otherwise provided in this
     Agreement, the options granted pursuant to this Award shall become 100%
     vested, and therefore fully exercisable, on the first anniversary of the
     Award Date and shall remain in effect until the EARLIEST of (a) the date on
     which all options granted hereunder have been exercised, (b) the date on
     which the options granted hereunder have terminated pursuant to the
     provisions of Sections 1 or 6 of this Agreement, or (c) the tenth
     anniversary of the Award Date ("Option Term"). No less than one thousand
     (1,000) shares may be purchased upon any one exercise of options granted
     pursuant to this Award unless the number of shares purchased at such time
     is the total number of shares in respect of which the options hereby
     granted are then exercisable. In no event shall any option granted hereby
     be exercisable for a fractional share.
 
          4. METHOD OF EXERCISING OPTIONS AND PAYMENT OF OPTION PRICE. Subject
     to the terms and conditions of this Agreement, the options granted pursuant
     to this Award may be exercised by delivering to the Company at the office
     of its Treasurer, a written notice of the election to exercise all or a
     portion of the options granted pursuant to this Award. Each written notice
     shall be given in the form of EXHIBIT A attached
                                       63
<PAGE>   65
 
     hereto and signed by the Optionee or such other person entitled to exercise
     the options in question. Any such written notice shall, as an essential
     part thereof, be accompanied by payment in form satisfactory to the Company
     of the full exercise price of the options then to be exercised. Upon the
     proper exercise of the options granted pursuant to this Award, the Company
     shall issue in the name of the person exercising the options or such other
     name as that person may indicate, and shall deliver to such person, a
     certificate or certificates for the shares purchased. The Optionee agrees
     that as holder of this Award, the Optionee shall have no rights as a
     shareholder or otherwise in respect of any of the shares as to which the
     options granted pursuant to this Award shall not have been effectively
     exercised as herein provided.
 
          5. ASSIGNABILITY. The options granted pursuant to the terms of this
     Award shall not be transferable or assignable except (a) by the laws of
     descent and distribution, (b) to a spouse or lineal descendent (a "Family
     Member"), (c) to a trust for the exclusive benefit of a Family Member, or
     (d) to a partnership, limited liability company or other entity in which
     all the beneficial owners are Family Members. The Optionee shall promptly
     notify the Company of any transfer or assignment pursuant to (b), (c), or
     (d) above and, absent any such notification, the Company shall have no
     obligation to honor or recognize the same.
 
          6. TERMINATION. The options granted hereby shall terminate and be of
     no force or effect upon the expiration of the Option Term unless terminated
     prior to such time as provided below. The Optionee's options shall
     terminate or be exercisable as follows:
 
             (a) Termination of Employment or Directorship. If Termination of
        Employment or Termination of Directorship occurs, the options granted
        hereby shall terminate as of the date of Termination of Employment or
        Termination of Directorship, as applicable.
 
             (b) Retirement. Notwithstanding (a) immediately above, in the event
        of retirement from service to the Company or Subsidiary at an age not
        less than 55, the Optionee may exercise the options granted hereby
        within the shorter of three (3) years from the date of the Optionee's
        retirement or the expiration of the Option Term.
 
             (c) Disability. Notwithstanding (a) immediately above, upon the
        Optionee's Disability the options granted hereby are exercisable by the
        Optionee or the Optionee's legal representative, if any, for the shorter
        of three (3) years from the date of the Optionee's Disability or the
        expiration of the Option Term.
 
             (d) Death. Notwithstanding (a) immediately above, if (i) Optionee
        dies while serving as a director or employee of the Company or
        Subsidiary, the Optionee's estate, personal representative, or
        beneficiary (as applicable) shall have the right to exercise the options
        granted hereby for the shorter of three (3) years from the date of the
        Optionee's death or the expiration of the Option Term, and (ii) if
        Optionee dies within the period of time after retirement from service to
        the Company or Subsidiary during which the Optionee would have been
        entitled to exercise options granted hereby, the Optionee's estate,
        personal representative, or beneficiary (as applicable) shall have the
        right to exercise the options granted hereby for the shorter of three
        (3) years from the date of the Optionee's retirement or the expiration
        of the Option Term.
 
          7. CHANGE IN CONTROL. Notwithstanding any other provision of this
     Agreement, in the event a Change in Control, or execution of agreements
