CONDITIONS THAT MUST BE SATISFIED FOR THE MERGER TO OCCUR (Page 23)

    The following conditions must be met for us to complete the merger, in
addition to other customary conditions:

    - approval of the merger by Old Guard Group, Inc. shareholders;

    - acquisition of any additional insurance coverage as they shall reasonably
      require by Ohio Farmers;

      of the issued and outstanding shares shares of Old Guard; and

    - certain previously identified employees of Old Guard and its subsidiaries
      shall have entered into new employment agreements or executed waiver
      agreements.

    The merger also cannot be completed unless we obtain the approval of the
Pennsylvania, Delaware, Virginia and Ohio Departments of Insurance. Ohio Farmers
Insurance Company filed the required applications seeking approval of the merger
on July 11, 2000, July 20, 2000, August 1, 2000 and June 27, 2000, respectively.
Additionally, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
the merger may not be consummated until notifications have been given and
certain information and materials have been furnished to and reviewed by the
Department of Justice and the Federal Trade Commission and specified waiting
period requirements have been satisfied. Old Guard and Ohio Farmers will file
the pre-merger notification forms required by the Hart-Scott-Rodino Act with the
Department of Justice and the Federal Trade Commission in August, 2000. Although
we believe the regulatory approvals will be received in a timely manner, we
cannot be certain when or if we will obtain them.

TERMINATION AND AMENDMENT OF THE AGREEMENT AND PLAN OF REORGANIZATION (Page 23)

    Old Guard and Ohio Farmers can agree at any time to terminate the agreement
without completing the merger. There are a number of other circumstances and
conditions under which any of the parties can terminate or amend the Agreement
and Plan of Reorganization. For a more detailed discussion of the termination
provisions of the agreement, see the section of this proxy entitled
"Termination; Effect of Termination" on page 23.

<PAGE>
WHAT IF I DON'T AGREE WITH THE MERGER?

    In addition to voting "no" at the special meeting, under Pennsylvania law
you have the right to dissent from the merger and receive cash equal to the
"fair value" of your shares. See "Dissenters Rights of Appraisal" on Page 24 for
additional information. A copy of the full text of Section 1930 and Subchapter D
of Chapter 15 of the Pennsylvania Business Corporation Law regarding dissenters'
rights is attached to this proxy as "Annex C".

ORGANIZATION AND OPERATION AFTER THE MERGER (Page 12)

    In the acquisition of Old Guard Group, Inc., Westfield Merger Sub, Inc., the
wholly owned subsidiary of Ohio Farmers Insurance Company, and Old Guard will be
merged. The Board of Directors of Old Guard will resign and be replaced by a
Board of Directors elected by Ohio Farmers and the officers of Old Guard will
become the officers of the resulting entity until replaced.

STOCK OPTION AGREEMENT (Page 27)

    As a condition to Ohio Farmers entering into the agreement and to discourage
other companies from acquiring Old Guard Group, Inc., Old Guard granted Ohio
Farmers an option to purchase up to 367,000 shares of Old Guard common stock at
an exercise price of $12.00 per share. Ohio Farmers may exercise this option
only if another party seeks to gain control of Old Guard. We do not believe that
any of the events that would permit Ohio Farmers to exercise the option have
occurred as of the date of this proxy.

    The stock option agreement is attached to this proxy as EXHIBIT "B" to ANNEX

                                  MATTER NO. 1
              APPROVAL OF THE AGREEMENT AND PLAN OF REORGANIZATION

    In this section of the proxy statement we describe the material terms and
provisions of the proposed merger. A copy of the Agreement and Plan of
Reorganization is attached to this proxy statement as ANNEX "A." We urge all
shareholders to read the agreement carefully.

    The agreement provides that:

    - Ohio Farmers Insurance Company will acquire Old Guard Group, Inc. through
      a merger of Westfield Merger Sub, Inc. and Old Guard Group, Inc.;

    - Old Guard shareholders will receive Twelve Dollars ($12.00) for each share
      of Old Guard Group, Inc. common stock that they own if the merger is
      completed.

BACKGROUND OF THE MERGER

    The Old Guard Board of Directors has long believed that Old Guard needed to
grow in order to remain competitive in the property and casualty insurance
market. This perception was one of the driving forces behind the decision to
form Old Guard Group, Inc. and convert the Old Guard operating subsidiaries from
mutual to stock form. This process began in 1996 and culminated with the
successful conversion of three principal operating subsidiaries from mutual to
stock form on February 11, 1997. After the conversion, management believed that,
as a public company, Old Guard was positioned to make acquisitions, or, failing
that, to affiliate with a larger company to achieve the scale necessary to
compete.

    Old Guard did successfully complete three smaller acquisitions, the
acquisition of First Delaware Insurance Company, the acquisition of New Castle
Mutual Insurance Company (now merged into Old Guard Insurance Company) and the
acquisition of Southern Title Insurance Company. While these acquisitions have
increased Old Guard's direct written premium volume to over $120 million
annually and diversified its mix of business and risk, management believes that
significantly greater scale and diversification is needed to remain competitive.
Old Guard has not been able to achieve any acquisitions of the size management
believes is necessary to achieve the desired scale.

    Two principal factors have impeded Old Guard's ability to grow through
acquisition. First, Old Guard has achieved significant profitability in only one
of the three completed fiscal years since it became a public company. This has
had a depressing effect on Old Guard's stock price and therefore has reduced the
value of Old Guard stock as acquisition currency. Second, because the conversion
of the Old Guard subsidiaries was accomplished under a new statute that
fundamentally changed the way in which Pennsylvania mutual insurance companies
convert from mutual to stock form, that conversion has been challenged legally
in a class action lawsuit brought by two policyholders purportedly on behalf of
all policyholders. To date, Old Guard has successfully defended this lawsuit.
All constitutional claims have been defeated and management remains confident
that it will ultimately prevail on all remaining claims. However, the case is
still at the pre-trial stage and may continue for some time. The uncertainty
created by this litigation has also hindered Old Guard's ability to effect
significant acquisitions.

    Because of Old Guard's inability to effect any larger acquisitions,
management and the Board of Directors concluded that it was necessary to
consider other alternatives. At the February 1999 Board meeting management
recommended, and the Board adopted, a formal policy requiring the Board to study
strategic alternatives, including sale of the company, at least annually. At
that February meeting the Board also authorized Mr. Hosler to contact companies
that may be potential merger partners. Shortly thereafter, Old Guard retained a
financial advisor to assist with the study of strategic alternatives.

                                       10
<PAGE>
    On January 12, 1999, Mr. Hosler and Mr. Blair, the chairman of the Westfield
Companies, had very preliminary conversations about a possible combination. As a
result of the Board's February actions, Mr. Hosler invited Mr. Blair to visit
Old Guard's headquarters on March 19, 1999 and Mr. Blair did so. More general
merger discussions ensued. Old Guard agreed to provide the Westfield Companies
with due diligence materials and did so in May 1999. Also in May 1999, Old
Guard's Board of Directors received a report from its financial advisor
regarding strategic alternatives. The report recommended that Old Guard explore
merger prospects with four companies, including the Westfield Companies.

    On June 1, 1999, Mr. Hosler visited the Westfield Companies headquarters for
additional discussions and a subsequent meeting was held at Old Guard's
headquarters in Lancaster on July 2, 1999. At that meeting, Mr. Blair expressed
the view that the uncertainty caused by the existence of the class action
litigation made valuation of Old Guard difficult and created a substantial
deterrent to the Westfield Companies' ability to make an offer that Old Guard
would find acceptable. A similar concern regarding the litigation was raised by
two of the other three companies with whom Old Guard had held discussions. As a
result, in July 1999, the Old Guard Board decided to temporarily suspend merger
discussions and Mr. Hosler informed Mr. Blair of this decision in August 1999.
During the remainder of 1999, Mr. Hosler explored resolution of the litigation
and other loss mitigation options and only limited discussions were held with
the Westfield Companies and other potential acquirors.

    In October 1999, the Old Guard Board authorized Mr. Hosler to terminate Old
Guard's existing financial advisor and retain Cochran, Caronia & Co. to act as
Old Guard's financial advisor. Cochran, Caronia & Co. provided a report to the
Board at its November meeting concerning various strategic alternatives and
identifying potential merger partners, including the Westfield Companies. The
board authorized Cochran, Caronia & Co. to seek preliminary expressions of
interest from potential merger partners. Based upon this instruction, Cochran,
Caronia & Co. approached 20 potential merger partners for the purpose of
obtaining expressions of interest. Cochran, Caronia & Co. updated the board on
the status of discussions with these potential merger partners at meetings held
in January and February 2000.

    Mr. Hosler renewed direct merger discussions with the Westfield Companies on
February 4, 2000, in part due to the fact that Old Guard's 1999 results would
again be weak. Additional discussions were also begun with potential merger
candidates as well as with two of the companies with whom discussions had been
held in the Summer and Fall of 1999. The Westfield Companies and other potential
merger partners performed additional due diligence in February and March, 2000.
Preliminary indications of interest valued the Company at a 10% to 25% discount
to the fully diluted book value, or approximately $18 per share. In March 2000,
after completing its due diligence, the Westfield Companies informed Old Guard
that it would not proceed and withdrew its indication of interest. Discussions
with other parties that had performed material due diligence further indicated
that this valuation was not achievable. In late April 2000, Cochran, Caronia &
Co. renewed discussions with Westfield and three other companies in an attempt
to negotiate a transaction. Westfield and its advisors and counsel negotiated
the price and the material terms of the Agreement and Plan of Reorganization. On
May 9, 2000, the Old Guard Board reviewed the financial terms of the Westfield
and two additional proposed transactions with Cochran, Caronia & Co. Counsel for
Old Guard also reviewed in detail the Board's fiduciary duties and the material
terms of the Agreement and Plan of Reorganization and Cochran, Caronia & Co.
orally advised the board of its opinion that the merger consideration was fair,
from a financial point of view, to the Old Guard shareholders. The Old Guard
Board and the Ohio Farmers Board each approved the transaction in principal on
May 9, 2000. The Agreement and Plan of Reorganization was executed on the
evening of May 10, 2000 and announced on May 11, 2000 prior to the commencement
of trading.

REASONS FOR THE MERGER

    The Old Guard Group, Inc. Board of Directors believes that the merger is
fair to, and in the best interests of, Old Guard Group, Inc. and its
shareholders. In reaching these conclusions, the Old Guard board considered a
number of factors, including the following:

    - the need to achieve scale and diversification to remain competitive;

    - Old Guard's inability to achieve scale and diversification because of weak
      operating results and the existence of the class action litigation;

    - Old Guard's historical and projected operating results and financial
      condition;

    - the economic, business and competitive climate for insurance companies in
      Pennsylvania and Ohio Farmers business plan for strengthening Old Guard's
      competitive position;

    - the intention of the Westfield Companies to maintain the Lancaster,
      Pennsylvania offices of Old Guard;

    - the creation of career opportunities for Old Guard employees through
      employment with a larger insurance entity;

    - the opinion of Cochran, Caronia & Co. that the consideration to be paid to
      the Old Guard shareholders was fair from a financial point of view.

    This list of factors considered by the Old Guard board is not exhaustive,
but is intended to highlight the material factors considered by the Old Guard
board. Individual directors may have given different weights to these factors in
reaching their decision; however, the Old Guard board did not assign specific
weights or priority to any one factor.

    Accordingly, the Old Guard board recommends that shareholders vote FOR
approval of the Agreement and Plan of Reorganization.

EFFECT OF THE MERGER

    If the agreement is approved by the shareholders of Old Guard, Ohio Farmers
will acquire Old Guard through a merger of Westfield and Old Guard. Ohio Farmers
will pay Twelve Dollars ($12.00) per share for all of the issued and outstanding
shares of Old Guard common stock. The combined Old Guard/Westfield company will
be a wholly owned subsidiary of Ohio Farmers Insurance Company.

    All property, rights, debts and obligations of both Westfield and Old Guard
will automatically transfer to and vest in the surviving corporation in
accordance with applicable law. Existing directors of Old Guard will immediately
resign and will be replaced by directors elected by Ohio Farmers. The current
officers of Old Guard will be the initial officers of the surviving company.

CONVERSION PRICE

    On the effective date of the merger, each outstanding share of Old Guard
common stock will automatically convert into the right to receive Twelve Dollars
($12.00) in cash for each share of Old Guard common stock owned as of the date
of the merger.

    On or prior to the effective date of the merger, each outstanding option,
warrant or similar right to purchase shares of Old Guard common stock will be
terminated. If and only if the exercise price of such option, warrant or right
is less than Twelve Dollars ($12.00), then the holders of the terminated
options, warrants or rights will be entitled to receive from Old Guard the
difference in cash between the option, warrant or right exercise price and
Twelve Dollars ($12.00).

OPINION OF OLD GUARD INDEPENDENT FINANCIAL ADVISOR

    Old Guard retained Cochran, Caronia & Co. (CC&Co) to act as its financial
advisor in connection with the proposed merger. In connection with its
engagement, Old Guard requested that CC&Co evaluate the fairness, from a
financial point of view, of the consideration to be received in the merger by
holders of Old Guard common stock. On May 9, 2000, at a meeting of the Old Guard
board held to evaluate the proposed merger, CC&Co delivered to the Old Guard
board a preliminary oral opinion (which opinion was confirmed by delivery of a
written opinion dated May 10, 2000, the date of execution of the merger
agreement) to the effect that, as of the date of the opinion and based on and
subject to the matters described in the opinion, the merger consideration was
fair, from a financial point of view, to the holders of Old Guard common stock.

    In arriving at its opinion, CC&Co:

    - reviewed financial terms and conditions of the merger agreement;

    - held discussions with senior officers, directors and other representatives
      and advisors of Old Guard concerning the business, operations and
      prospects of Old Guard;

    - examined publicly available business and financial information relating to
      Old Guard;

    - examined financial forecasts and other information and data for Old Guard
      that were provided to or otherwise discussed with CC&Co by the management
      of Old Guard, including actuarial reserve analyses prepared by the
      independent actuaries of Old Guard;

    - reviewed the financial terms of the merger as described in the merger
      agreement in relation to, among other things, current and historical
      market prices and trading volumes of Old Guard common stock, the
      historical and projected earnings and other operating data of Old Guard,
      and the capitalization and financial condition of Old Guard;

    - considered, to the extent publicly available, the financial terms of other
      transactions recently effected that CC&Co considered relevant in
      evaluating of the merger;

    - analyzed financial, stock market and other publicly available information
      relating to the businesses of other companies whose operations CC&Co
      considered relevant in evaluating those of Old Guard; and

    - conducted other analyses and examinations and considered other financial,
      economic and market criteria as CC&Co deemed appropriate in arriving at
      its opinion.

    In rendering its opinion, CC&Co assumed and relied, without independent
verification, on the accuracy and completeness of all financial and other
information and data that it reviewed or considered. With respect to financial
forecasts and information and data, the management of Old Guard advised CC&Co
that they were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the management of Old Guard as to the
future financial performance of Old Guard.

    CC&Co also was advised that the actuarial reserve analyses relating to Old
Guard prepared by its independent actuaries were reasonably prepared on bases
reflecting the best currently available estimates and judgments of the actuaries
as to Old Guard's reserves. CC&Co is not an actuarial firm and its services did
not include any actuarial determinations or evaluations by it or an attempt to
evaluate actuarial assumptions, nor did CC&Co express any views as to matters
relating to Old Guard's reserves, including, without limitation, the adequacy of
Old Guard's reserves. CC&Co did not make and, except for the actuarial reserve
analyses prepared by Old Guard's independent actuaries, was not provided with an
independent evaluation or appraisal of the assets, liabilities (contingent or
otherwise) or reserves of Old Guard, and did not make any physical inspection of
the properties or assets of Old Guard. CC&Co assumed, with Old Guard's consent,
that in the course of obtaining the necessary

                                       13
<PAGE>
regulatory approvals for the merger, no limitations, restrictions or conditions
would be imposed that would have a material adverse effect on the ability of the
parties to consummate the merger. CC&Co further assumed that the transactions
contemplated by the merger agreement would be consummated on the terms described
in the merger agreement, without the waiver of any material rights, terms or
conditions thereof by Old Guard.

    In connection with its engagement, CC&Co was requested to approach, and held
discussions with, third parties to solicit indications of interest in the
possible acquisition of Old Guard. CC&Co expressed no view as to, and its
opinion does not address, the relative merits of the merger as compared with any
alternative business strategies that might exist for Old Guard or the effect of
any other transaction in which Old Guard might engage. CC&Co's opinion was
necessarily based on information available, and financial, stock market and
other conditions and circumstances existing and disclosed to CC&Co, as of the
date of its opinion. Although CC&Co evaluated the merger consideration from a
financial point of view, CC&Co was not asked to and did not recommend the
specific form or amount of consideration payable in the merger, which was
determined through negotiation between Old Guard and the Westfield Companies. No
other instructions or limitations were imposed by Old Guard on CC&Co with
respect to the investigations made or procedures followed by CC&Co in rendering
its opinion.

    THE FULL TEXT OF CC&CO'S WRITTEN OPINION DATED THE DATE OF THIS PROXY
STATEMENT, WHICH DESCRIBES THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED TO THIS PROXY STATEMENT AS
ANNEX B AND IS INCORPORATED INTO THIS PROXY STATEMENT BY REFERENCE. CC&CO'S
OPINION IS DIRECTED TO THE OLD GUARD BOARD AND RELATES ONLY TO THE FAIRNESS OF
THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW, DOES NOT ADDRESS ANY
OTHER ASPECT OF THE MERGER OR ANY RELATED TRANSACTION AND DOES NOT CONSTITUTE A
RECOMMENDATION TO ANY STOCKHOLDER WITH RESPECT TO HOW TO VOTE AT THE SPECIAL
MEETING OR WITH RESPECT TO ANY OTHER MATTER RELATING TO THE PROPOSED MERGER.

    In preparing its opinion, CC&Co performed a variety of financial and
comparative analyses, including those described below. The summary of these
analyses is not a complete description of the analyses underlying CC&Co's
opinion. The preparation of a fairness opinion is a complex analytical process
involving various determinations as to the most appropriate and relevant methods
of financial analysis and the application of those methods to the particular
circumstances and, therefore, a fairness opinion is not readily susceptible to
summary description. Accordingly, CC&Co believes that its analyses must be
considered as a whole and that selecting portions of its analyses and factors,
without considering all analyses and factors, could create a misleading or
incomplete view of the processes underlying its analyses and opinion.

    In its analyses, CC&Co considered industry performance, general business,
economic, market and financial conditions and other matters existing as of the
date of its opinion, many of which are beyond the control of Old Guard. No
company, transaction or business used in those analyses as a comparison is
identical to Old Guard or the proposed merger, and an evaluation of those
analyses is not entirely mathematical. Rather, the analyses involve complex
considerations and judgments concerning financial and operating characteristics
and other factors that could affect the acquisition, public trading or other
values of the companies, business segments or transactions analyzed.

    The estimates contained in CC&Co's analyses and the valuation ranges
resulting from any particular analyses are not necessarily indicative of actual
values or predictive of future results or values, which may be significantly
more or less favorable than those suggested by its analyses. In addition,
analyses relating to the value of businesses or securities do not necessarily
purport to be

                                       14
<PAGE>
appraisals or to reflect the prices at which businesses or securities actually
may be sold. Accordingly, CC&Co's analyses and estimates are inherently subject
to substantial uncertainty.

    CC&Co's opinion and analyses were only one of many factors considered by the
Old Guard board in its evaluation of the merger and should not be viewed as
determinative of the views of the Old Guard board or management with respect to
the merger consideration or the proposed merger.

    The following is a summary of the material financial analyses performed by
CC&Co in connection with rendering its opinion:

    SELECTED COMPANIES ANALYSIS.--Using publicly available information, CC&Co
analyzed the market values and trading multiples of certain selected publicly
traded small-cap commercial/personal lines insurance companies, which are listed
below. Although there were no public companies with precisely the same mix of
businesses and financial conditions as Old Guard, CC & Co. believes the
companies listed below were reasonably comparable.

    All multiples were based on stock prices available as of May 9, 2000.
Estimated financial data for the selected companies were based on research
analysts' estimates, and estimated financial data for Old Guard were based on
internal estimates of Old Guard's management. CC&Co compared market values of
Old Guard and the selected companies as a multiple of, among other things,
calendar year 2000 and 2001 estimated earnings computed in accordance with
generally accepted accounting principles, commonly known as GAAP, 1999 year end
statutory surplus, and GAAP book value as of March 31, 2000. CC&Co then applied
a range of selected multiples derived from the selected companies of calendar
year 2000 and 2001 estimated GAAP earnings, 1999 year end statutory surplus, and
latest GAAP book value as of March 31, 2000 to corresponding financial data of
Old Guard in order to derive an implied equity reference range for Old Guard.

    PRECEDENT TRANSACTIONS ANALYSIS.--Using publicly available information,
CC&Co reviewed the financial terms and implied transaction value multiplies paid
or proposed to be paid in certain selected transactions among
commercial/personal lines insurance companies. Although no transaction utilized
in this analysis was identical to the merger, CC&Co believes the transactions
transactions listed below were reasonable comparable.

    CC&Co compared purchase prices in the selected transactions as a multiple
of, among other things, latest statutory surplus and GAAP book values. All
multiples were based on publicly available financial information from the
selected transaction. CC&Co then applied a range of selected multiples derived
from the selected transactions of latest statutory surplus and GAAP book value
to Old Guard's

    DISCOUNTED CASH FLOW ANALYSIS.--CC&Co performed a discounted cash flow
analysis of Old Guard's projected dividendable cash flows during calendar year
2000 through 2004 based on internal estimates of Old Guard's management. CC&Co
derived an implied equity reference range for Old Guard by applying a terminal
growth rate of 5% to Old Guard's 2004 estimated statutory earnings and a range
of selected discount rates from 10% to 15%.

    VALUATION RESULTS.--The combination of these various valuation methodologies
resulted in an implied equity reference range for Old Guard of approximately
$40-$50 million (approximately $10-$13 per share) compared to the merger
consideration of approximately $45 million ($12 per share).

    OTHER FACTORS.--In rendering its opinion, CC&Co also reviewed and considered
other factors, including:

    - Historical and projected financial data for Old Guard, including Old
      Guard's financial performance and financial position as well as financing
      options available to Old Guard;

    - Historical trading prices for Old Guard common stock.

    MISCELLANEOUS.--Under the terms of its engagement, Old Guard has agreed to
pay CC&Co for its financial advisory services upon completion of the merger an
aggregate fee of $500,000. Old Guard also has agreed to reimburse CC&Co for
reasonable travel and other out-of-pocket expenses incurred by CC&Co in
performing its services, including the fees and expenses of its legal counsel,
and to indemnify CC&Co and related persons against liabilities, including
liabilities under the federal securities laws, arising out of its engagement.

                                       16
<PAGE>
    In the ordinary course of business, CC&Co and its affiliates may actively
trade or hold the securities of Old Guard for the account of customers and,
accordingly, may at any time hold a long or short position in those securities.

    CC&Co is a full service investment bank focused exclusively on the insurance
industry and was selected by Old Guard based on its experience and expertise in
the industry. CC&Co regularly engages in the valuation of insurance company
securities in connection with business combinations, investments and other
transactions.

REGULATORY APPROVALS

    The Pennsylvania, Virginia, Delaware and Ohio Departments of Insurance must
approve the acquisition and the merger. Ohio Farmers Insurance Company filed
applications for approval with each state's Department of Insurance on July 11,
2000, August 1, 2000, July 20, 2000 and June 27, 2000, respectively.

    Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 and the rules
promulgated under the Hart-Scott-Rodino Act, the merger may not be consummated
until notifications have been given and certain information and materials have
been furnished to and reviewed by the Department of Justice and the Federal
Trade Commission and specified waiting period requirements have been satisfied.
Old Guard and Ohio Farmers will file the pre-merger notification forms required
by the Hart-Scott-Rodino Act with the Department of Justice and the Federal
Trade Commission in August, 2000. Unless a request for additional information is
made by the reviewing federal agency, or early termination of the waiting period
is granted, the waiting period under the Hart-Scott-Rodino Act applicable to the
merger will expire 30 days after the filing. At any time prior to or after the
consummation of the merger, the Department of Justice or the Federal Trade
Commission could take action under the federal antitrust laws, including seeking
to enjoin the merger or seeking conditions thereon. State antitrust authorities
and private parties in certain circumstances may bring legal action under the
antitrust laws seeking to enjoin the merger or impose conditions.

best efforts to preserve its business organizations intact, to maintain good
relationships with employees and to preserve the goodwill of customers and
others with whom business relationships exist. In addition, Old Guard agreed to

of business, consistent with past practice, except as otherwise required by the

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

    The following is a description of the material United States federal income
tax consequences of the merger of Old Guard and Westfield. Except where we state
otherwise, this summary deals only with the disposition of Old Guard common
stock ("Common Stock") held as a capital asset by a holder who is a United
States person (as defined below).

    A "United States person" is any beneficial owner who is one of the
following:

    - a citizen or resident of the United States;

    - a corporation or other entity taxable as a corporation created or
      organized in or under the laws of the United States or any political
      subdivision of the United States;

    - an estate the income of which is subject to United States federal income
      taxation regardless of its source; or

    - any trust (x) that is subject to the supervision of a court within the
      United States and the control of one or more United States persons as
      described in section 7701(a)(30) of the Internal Revenue Code of 1986, as
      amended (the "Code"), or (y) that has a valid election in effect under
      applicable U.S. Treasury regulations to be treated as a United States
      person.

    A "Non-U.S. Holder" is a beneficial owner who is not a United States person.

    If a partnership holds Common Stock, the tax treatment of a partner will
generally depend upon the status of the partner and upon the activities of the
partnership. If you are a partner of a partnership holding Common Stock, we
suggest that you consult your tax advisor.

    Your tax treatment may vary depending on your particular situation. Except
where noted, this summary does not deal with special situations. For example,
this summary does not address:

    - tax consequences to holders who may be subject to special tax treatment,
      such as dealers in securities or currencies, traders in securities that
      elect to use the mark to market method of accounting for their securities,
      real estate investment trusts and regulated investment companies;

    - tax consequences to persons who hold Common Stock as part of a hedging,
      integrated, conversion or constructive sale transaction or a straddle;

    - tax consequences to holders of Common Stock whose "functional currency" is
      not the U.S. dollar;

    - alternative minimum tax consequences, if any; or

    - any state, local or foreign tax consequences.

    This summary is based on the Code, the Treasury regulations promulgated
under the Code and administrative and judicial interpretations. These income tax
laws, regulations and interpretations, however, may change at any time. Any
change could be retroactive to the date of the merger.

    The authorities on which this summary is based are subject to various
interpretations. Either the IRS or the courts could disagree with the
explanations or conclusions contained in this summary.

    You should consult your tax advisor with respect to the tax consequences to
you of the merger and your disposition of Common Stock, including the tax
consequences under state, local, foreign, and other tax laws.

THE MERGER

    Under the Agreement and Plan of Reorganization, the merger is structured so
that, on the effective date, (a) Westfield and Old Guard will merge, and
(b) each outstanding share of Common

                                       20
<PAGE>
Stock will automatically convert into the right to receive twelve dollars
($12.00) in cash. For United States federal income tax purposes, the
transactions will be characterized as a reverse triangular merger in which the
holders of the Common Stock will be treated as selling their Common Stock to
Ohio Farmers Insurance Company for cash.

    If a holder of Common Stock dissents from the merger (see "Dissenters Rights
of Appraisal"), the dissenting shareholder's shares of Common Stock will be
converted into the right to receive cash from the surviving corporation in an
amount equal to the "fair value" of the dissenting shareholder's shares. For
United States federal income tax purposes, dissenting shareholders will be
treated as selling their Common Stock to the surviving corporation for cash.

SALE OF COMMON STOCK

    Upon the sale of your Common Stock, you will recognize capital gain or loss
in accordance with your regular method of accounting in an amount equal to the
difference between the proceeds you receive and your tax basis in the Common
Stock. The resulting gain or loss will be either short-term or long-term capital
gain or loss depending on your holding period for your Common Stock. Capital
gains of individuals derived with respect to capital assets held for more than
one year are subject to tax at a maximum rate of 20%. Your ability to deduct
capital losses is subject to limitations.

NON-UNITED STATES HOLDERS

    The following discussion only applies to you if you are a Non-U.S. Holder.

U.S. FEDERAL WITHHOLDING TAX

    Except as discussed below, the 30% U.S. federal withholding tax will not
apply to any gain that you realize on the sale of your Common Stock.

U.S. FEDERAL INCOME TAX

    Any gain or income you realize on the disposition of your Common Stock will
generally not be subject to U.S. federal income or withholding tax unless:

    - that gain or income is effectively connected with the conduct of a trade
      or business in the United States by you;

    - you are an individual who is present in the United States for 183 days or
      more in the taxable year of that disposition, and certain other conditions
      are met; or

    - the Company is or has been a "United States real property holding
      corporation" for United States federal income tax purposes, and certain
      other conditions are met.

    The Company believes that it never has been, is not currently and is not
likely to be treated as a United States real property holding corporation.

    Special rules may apply to you if you are a "controlled foreign
corporation," "passive foreign investment company," "foreign personal holding
company," or company that accumulates earnings for the purpose of avoiding tax,
and are subject to special treatment under the Code. If you are such an entity,
you should consult your tax advisor to determine the United States federal,
state, local and other tax consequences that may be relevant to you.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    If you are a United States person, unless you are an exempt recipient, such
as a corporation, the proceeds you receive from the sale of Common Stock will be
subject to information reporting and may

                                       21
<PAGE>
be subject to United States federal backup withholding at the rate of 31% if you
fail to supply an accurate taxpayer identification number or otherwise fail to
comply with applicable United States information reporting or certification
requirements.

    If you are a Non-U.S. Holder, payment of the proceeds of sale of Common
Stock within the United States or conducted through certain U.S. related
financial intermediaries is subject to both backup withholding and information
reporting unless the beneficial owner certifies under penalties of perjury that
it is a Non-U.S. Holder (and the payor does not have actual knowledge that the
beneficial owner is a United States person) or the holder otherwise establishes
an exemption.

    Any amounts withheld from you under the backup withholding rules generally
will be allowed as a refund or a credit against your United States federal
income tax liability, provided the required information is furnished to the IRS.

    This is not a complete description of all the federal income tax
consequences of the merger and, in particular, does not address tax
considerations that may affect the treatment of shareholders who acquired their
Old Guard common stock pursuant to the exercise of employee stock options or
otherwise as compensation, or shareholders that are exempt organizations or who
are not citizens or residents of the United States. Your individual
circumstances may affect the tax consequences of the merger to you. In addition,
no information is provided herein with respect to the tax consequences of the
merger under applicable state, local, or foreign laws. Accordingly, you are
advised to consult a tax advisor as to the specific tax consequences of the
merger to you.

EXPENSES

    Old Guard and Ohio Farmers will each pay all their respective costs and
expenses, including fees and expenses of financial consultants, accountants and
legal counsel.

NO SOLICITATION

    The agreement prohibits Old Guard or any of its affiliates or
representatives from directly or indirectly:

    - taking any action to solicit, initiate or encourage any takeover proposal;
      or

    - engaging in negotiations with, or disclosing any nonpublic information
      relating to Old Guard or any of its subsidiaries; or

    - giving access to the properties, books or records of Old Guard or any of
      its subsidiaries to, any person that has advised Old Guard that it may be
      considering making, or that has made, a takeover proposal.

    Old Guard's Board of Directors is not prohibited from disclosing to Old
Guard's shareholders its position with respect to a tender offer pursuant to
Rules 14d-9 and 14e-2 promulgated under the Securities Exchange Act of 1934. In
addition, if the Board of Directors of Old Guard receives an unsolicited
takeover proposal and subsequently receives a written opinion from Cochran,
Caronia & Co. that such takeover proposal, if consummated, would be materially
more financially favorable to Old Guard's shareholders and the Board of
Directors receives advice of outside counsel that in outside counsel's judgment
the failure to take certain actions would constitute a breach of their fiduciary
duty, Old Guard may, subject to certain conditions, enter into negotiations with
the entity making the unsolicited takeover proposal.

AMENDMENT; WAIVERS

    Subject to any applicable legal restrictions, at any time prior to
completion of the merger, Old Guard, Ohio Farmers and Westfield may:

    - amend the agreement;

    - revise the time for the performance of any of the obligations or other
      acts of Old Guard, Ohio Farmers and Westfield required in the agreement;

    - correct any inaccuracies in the representations and warranties contained
      in the agreement; or

    - waive compliance with any of the agreements or conditions contained in the
      agreement, except for the requirements of shareholder approvals,
      regulatory approvals and the absence of any order, decree, or injunction
      preventing the merger.

    After the shareholders of Old Guard have approved the agreement, Old Guard,
Ohio Farmers and Westfield cannot modify the amount nor the form of
consideration that the Old Guard shareholders will receive upon completion of
the merger or take any action that would otherwise materially adversely affect
any shareholder without shareholder approval.

CONDITIONS TO THE MERGER

    The obligations of Old Guard and Ohio Farmers to complete the merger are
subject to various conditions, which include, among other customary provisions
for transactions of this type, the following:

    - approval of the merger by Old Guard shareholders;

    - receipt of all required regulatory approvals, including the expiration or
      termination of any notice and waiting periods;

    - the absence of any legal order prohibiting the merger;

    - delivery of opinions by each company's respective legal counsel;

    - acquisition by Ohio Farmers of additional insurance coverage as they shall
      reasonably require;

    - dissenting shareholders shall not hold more than 7% of the issued and
      outstanding shares of Old Guard; and

    - certain previously identified employees of Old Guard and its subsidiaries
      shall have entered into new employment agreements or executed waiver
      agreements.

    Except for the requirements of shareholder approvals, regulatory approvals
and the absence of any legal order preventing the merger, each of the conditions
described above may be waived in the manner and to the extent described in
"--Amendment; Waivers" on page 23.

TERMINATION; EFFECT OF TERMINATION

    Old Guard, Ohio Farmers, and Westfield may terminate the agreement at any
time prior to completion of the merger by mutual written consent.

    In addition, Old Guard, Ohio Farmers or Westfield may terminate the
agreement at any time prior to completion of the transaction:

    - if the closing date of the merger does not occur before November 30, 2000,
      unless the failure to close by that date results from the failure of the
      party seeking to terminate the agreement to materially perform any of its
      obligations; or

                                       23
<PAGE>
    - if any party has received a final nonappealable order from a regulatory
      authority denying a required approval or consent, unless the denial
      results from the failure of the party seeking to terminate the agreement
      to materially perform any of its obligations; or

    - if any party has materially breached any material covenant or
      representation contained in the agreement which would have a material
      adverse effect on the assets, financial condition or results of operation
      of the other party on a consolidated basis, but only if the breach remains
      uncured.

    Ohio Farmers alone may terminate the agreement:

    - if the Board of Directors of Old Guard fails to recommend and endorse the
      agreement or withdraws or modifies a prior recommendation in a manner
      adverse to Ohio Farmers; or

    - if the Board of Directors of Old Guard fails to call a special meeting of
      the shareholders on or before August 31, 2000; or

    - if the Board of Directors of Old Guard fails to hold a special meeting of
      the shareholders on or before September 30, 2000.

    Old Guard alone may terminate the agreement at any time prior to completion
of the merger:

    - if the Board of Directors of Old Guard receives a superior proposal (as
      defined in the agreement) and has complied with the termination provisions
      of the agreement.

    If the agreement is terminated under certain circumstances, Old Guard will
be required to pay Ohio Farmers a termination fee in the amount of $2,500,000.
The specific circumstances of termination that would give rise to payment of the
termination fee are contained in Section 8 of the agreement (attached to this
proxy statement as ANNEX "A.")

    In the event that Old Guard, Ohio Farmers or Westfield terminates the
agreement, other than the termination fee described above and the payment of
expenses of the other party under certain circumstances, none of the parties
will have any continuing liability or obligation other than the obligations
dealing with confidentiality and any liabilities resulting from willful breach
or fraud. Under certain conditions, the Option Agreement would survive the
termination for a period of up to 181 days after the termination of the
Agreement and Plan of Reorganization.

DISSENTERS' RIGHTS OF APPRAISAL

    Pursuant to the Pennsylvania Business Corporation Law, shareholders of Old
Guard have the right to dissent from the merger, and to obtain payment of the
"fair value" of their Old Guard common stock, if the merger is consummated. The
term "fair value" means the value of Old Guard common stock immediately before
completion of the merger, taking into account all relevant factors, but
excluding any appreciation or depreciation in anticipation of the merger.

    The following summary of the steps to be taken if the right to dissent is to
be exercised is qualified in its entirety by the full text of Section 1930 and
Subchapter D of Chapter 15 of the Pennsylvania law, which are attached as ANNEX
"C" to this proxy statement. Each step must be taken in the indicated order and
in strict compliance with the applicable provisions of the statute in order to
perfect dissenters' rights. The failure of any Old Guard shareholder to comply
with the aforesaid steps will result in the shareholder receiving the
consideration contemplated by the agreement. Any shareholder of Old Guard who
contemplates exercising the right to dissent is urged to read carefully the
provisions of Section 1930 and Subchapter D of Chapter 15 of the BCL.

    Any written notice or demand which is required in connection with the
exercise of dissenters' rights, whether before or after the closing date, must
be sent to Old Guard Group, Inc., 2929 Lititz Pike, P.O. Box 3010, Lancaster,
Pennsylvania 17604-3010 (Attention: Corporate Secretary).

                                       24
<PAGE>
    A shareholder who wishes to dissent must file with Old Guard prior to the
vote of shareholders on the merger at the special meeting a written notice of
intention to demand that he be paid the fair value for his shares of Old Guard
common stock, if the merger is effected, must effect no change in the beneficial
ownership of his Old Guard common stock from the date of such filing through the
closing date, and must refrain from voting his Old Guard common stock to approve
the merger. Neither a proxy nor a vote against approval of the merger will
constitute the necessary written notice of intention to dissent. A beneficial
owner of Old Guard common stock whose shares are held of record in "street name"
by a brokerage firm or other nominee must obtain the written consent of such
record holder to such beneficial owner's exercise of dissenters' rights and must
submit such consent to Old Guard no later than the time of the filing of his
notice of intention to dissent.

    If the merger is approved by the required vote of Old Guard's shareholders
at the special meeting, Old Guard will mail a notice to all dissenters who gave
due notice of intention to demand payment and who refrained from voting in favor
of the merger. The notice will state where and when a demand for payment must be
sent and certificates for Old Guard common stock must be deposited in order to
obtain payment, and will include a form for demanding payment and a copy of
Subchapter D of Chapter 15 of the Pennsylvania Business Corporation Law. The
time set for receipt of the demand for payment and deposit of stock certificates
will not be less than 30 days from the date of mailing of the notice.

    A shareholder who fails to timely demand payment or fails to timely deposit
stock certificates, as required by Old Guard's notice, will not have any right
to receive payment of the fair value of his Old Guard common stock.

    Promptly after completion of the merger, or upon timely receipt of demand
for payment if the merger already has been completed, Old Guard will either
remit to dissenters who have made demand and have deposited their stock
certificates the amount that Old Guard estimates to be the fair value of the Old
Guard common stock or give written notice that no such remittance is being made.
The remittance or notice will be accompanied by (i) a closing balance sheet and
an income statement of Old Guard for a fiscal year ending not more than
16 months before the date of remittance or notice, together with the latest
available interim financial statements, (ii) a statement of Old Guard's estimate
of the fair value of the Old Guard common stock, and (iii) notice of the right
of the dissenter to demand payment or supplemental payment under the
Pennsylvania Business Corporation Law, as the case may be, accompanied by a copy
of Subchapter D of Chapter 15 of the Pennsylvania Business Corporation Law. If
Old Guard does not remit the estimated fair value for shares with respect to
which demand for payment has been made and stock certificates have been
deposited, then Old Guard will return any certificates that have been deposited.
Returned certificates, and any certificates subsequently issued in exchange
therefor, will be marked to record the fact that demand for payment has been
made. Transferees of shares so marked shall not acquire any rights in Old Guard
other than those rights held by the original dissenter after such dissenter
demanded payment of fair value.

    If a dissenter believes that the amount stated or remitted by Old Guard is
less than the fair value of the Old Guard common stock he may send Old Guard his
own estimate of the fair value of the Old Guard common stock which shall be
deemed to be a demand for payment of the amount of the deficiency. If Old Guard
remits payment of its estimated value of a dissenter's Old Guard common stock
and the dissenter does not file his own estimate within 30 days after the
mailing by Old Guard of its remittance, the dissenter will be entitled to no
more than the amount remitted to him by Old Guard.

    Within 60 days after the latest to occur of completion of the merger, timely
receipt by Old Guard of any demands for payment, or timely receipt by Old Guard
of any estimates by dissenters of fair value, if any demands for payment remain
unsettled, Old Guard may file in the Court of Common Pleas of Lancaster County,
an application requesting that the fair value of the Old Guard common

                                       25
<PAGE>
stock be determined by the Court. In that case, all dissenters, wherever
residing, whose demands have not been settled shall be made parties to the
proceeding as in an action against their shares, and a copy of the application
shall be served on each dissenter.

    If Old Guard were to fail to file an application, then any dissenter, on
behalf of all dissenters who have made a demand and who have not settled their
claim against Old Guard may file an application in the name of Old Guard at any
time within the 30-day period after the expiration of the 60-day period and
request that the fair value be determined by the Court. The fair value
determined by the Court may, but need not, equal the dissenters' estimates of
fair value. If no dissenter files an application, then each dissenter entitled
to do so shall be paid Old Guard's estimate of the fair value of the Old Guard
common stock and no more, and may bring an action to recover any amount not
previously remitted, plus interest at a rate the Court finds fair and equitable.

    Old Guard intends to negotiate in good faith with any dissenting
shareholder. If after negotiation, a claim cannot be settled, then Old Guard
intends to file an application requesting that the fair value of the Old Guard
common stock be determined by the Court.

FINANCIAL INTERESTS OF DIRECTORS AND OFFICERS

    Certain members of management of Old Guard and its Board of Directors, may
have interests in the merger in addition to their interests as shareholders.

STOCK OPTIONS AND RESTRICTED STOCK AWARDS

    As of the record date, the directors and executive officers of Old Guard
hold options to purchase 153,664 shares of Old Guard common stock and have
received 59,730 restricted stock awards. On the effective date of the merger,
all unvested stock options and restricted stock awards immediately vest. If the
exercise price of an option is less than Twelve Dollars ($12.00) per share, then
each such option will convert into a right to receive the difference between
Twelve Dollars ($12.00) and the option exercise price.

INDEMNIFICATION; DIRECTORS AND OFFICERS INSURANCE

    The surviving entity after the merger has agreed to indemnify all directors
and officers of Old Guard as follows:

    - for a period the longer of (i) six years after the closing date or
      (ii) the final settlement of certain litigation events disclosed in the
      agreement, subject to maximum cost limitations, against all liabilities
      and expenses relating to claims, proceedings or investigations resulting
      from the person's status as a director, officer or employee of Old Guard
      or any Old Guard subsidiary, whether pertaining to matters existing prior
      to the merger and whether asserted prior to or after the merger; and

    - for a period of three (3) years following the merger, provide counsel to
      any eligible party and pay the reasonable fees and expenses of such
      counsel with respect to an indemnifiable claim.

    Ohio Farmers has agreed to use commercially reasonable efforts to obtain
indemnity coverage substantially similar to Old Guard's existing directors' and
officers' liability insurance policy, or a policy providing comparable coverage
amounts on terms no less favorable, covering persons currently covered by such
insurance

EMPLOYMENT AGREEMENTS.

    Ohio Farmers intends to enter into new employment agreements with certain
officers/employees of Old Guard that will replace their existing agreements. The
existing agreements of Old Guard officer/

                                       26
<PAGE>
employees are two and three year "evergreen" contracts that annually are
extended by an additional year. The Ohio Farmers agreements that will replace
these existing agreements will eliminate these "evergreen" provisions. In
consideration for these officers/employees entering into new employment
agreements and relinquishing the "evergreen" provisions of their existing
agreements, Ohio Farmers has agreed to include additional deferred compensation
provisions in their new employment agreements. In lieu of entering into new
employment agreements, certain other officers/employees will enter into
severance agreements that will contain additional deferred compensation similar
to those contained in the new employment agreements.

CERTAIN RELATED TRANSACTIONS

STOCK OPTION AGREEMENT

    General. As a condition to Ohio Farmers entering into the agreement, Old
Guard executed a stock option agreement, dated May 10, 2000, which permits Ohio
Farmers to purchase Old Guard common stock under the circumstances described
below.

    Under the stock option agreement, Ohio Farmers received an option to
purchase up to 367,000 shares of Old Guard common stock. This number represents
approximately 9.9% of the issued and outstanding shares of Old Guard common
stock on March 31, 2000. The exercise price per share to purchase Old Guard
common stock under the option is $12.00 per share. Ohio Farmers may only
exercise the option upon the occurrence of certain triggering events, which are
defined in the stock option agreement. None of the triggering events have
occurred to the best of Ohio Farmers' or Old Guard's knowledge as of the date of
this proxy statement.

    Effect of Stock Option Agreement. The stock option agreement, together with
Old Guard's agreement to not solicit other transactions relating to the
acquisition of Old Guard by a third party and the agreement of Old Guard's
directors and senior executive officers to vote their shares in favor of the
merger, may have the effect of discouraging persons from making a proposal to
acquire Old Guard.

    Certain attempts to acquire Old Guard or an interest in Old Guard would
cause the option to become exercisable. This would significantly increase a
potential acquirer's cost of acquiring Old Guard compared to the cost that would
be incurred without the stock option agreement.

    Terms of Stock Option Agreement. The following is a brief summary of the
material provisions of the stock option agreement. A complete copy of the stock
option agreement is included as EXHIBIT "B" to ANNEX "A" to this proxy
statement. We urge you to read it carefully.

    The option is exercisable only upon the occurrence of a triggering event or
a third-party takeover proposal as they are defined in the agreement.

    The option expires on the earlier of:

    - the effective date of the merger; or

    - termination of the agreement in accordance with its terms, except that if:

       - Ohio Farmers terminates the agreement as a result of an uncured breach
         by Old Guard which results in a material adverse effect on the assets,
         financial condition or results of operations of Ohio Farmers, or

       - at the time of termination of the agreement, a triggering event, or
         certain other events have occurred indicating a possible triggering
         event or competing transaction,

    then the stock option agreement continues until One Hundred Eighty-One
    (181) days after termination of the agreement.

                                       27
<PAGE>
    In the event of any change in Old Guard common stock by reason of stock
dividends, split-ups, recapitalizations, combinations, conversions, divisions,
exchanges of shares or the like, the number and kind of shares issuable under
the option are adjusted appropriately.

VOTING AGREEMENT

    The following is a brief summary of the material provisions of the voting
agreement. A complete copy of the voting agreement is included as EXHIBIT "C" to
ANNEX "A" to this proxy statement. We urge you to read it carefully.

    The voting agreement requires the directors, senior executive officers of
Old Guard, and two major shareholders, Gotham Capital, LLC and American
Re-Insurance Company, to vote all the shares of Old Guard owned by them in favor
of the merger and against any competing merger proposal. The directors, senior
executive officers and major shareholders hold approximately 24.53% of the
issued and outstanding shares of Old Guard.

    The voting agreement contains the usual and customary terms included in this
type of agreement. The voting agreement terminates upon:

    - notice by Ohio Farmers;

    - completion of the merger; or

    - termination of the Agreement and Plan of Reorganization.

                                  MATTER NO. 2
                                  ADJOURNMENT

    In the event that there are not sufficient votes to constitute a quorum or
approve the adoption of the agreement at the time of the special meeting, the
agreement could not be approved unless that special meeting was adjourned in
order to permit further solicitation of proxies. In order to allow proxies which
have been received by Old Guard at the time of the special meeting to be voted
for such adjournment, if necessary, Old Guard has submitted the question of
adjournment under such circumstances to its shareholders as a separate matter
for their consideration.

    The Boards of Directors of Old Guard recommends that shareholders vote their
proxies in favor of the respective adjournment proposals, so that their proxies
may be used for such purposes in the event it becomes necessary. Properly
executed proxies will be voted in favor of the respective adjournment proposal,
unless otherwise indicated thereon. If it is necessary to adjourn the special
meeting, no notice of the time and place of the adjourned special meeting is
required to be given to shareholders other than an announcement of such time and
place at the special meeting.

                      AGREEMENT AND PLAN OF REORGANIZATION

    This AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is made and
entered into as of May 10, 2000, by and among Ohio Farmers Insurance Company, an
Ohio corporation ("Acquiror"), Westfield Merger Sub, Inc., an Ohio corporation
and wholly owned subsidiary of Acquiror ("Merger Sub"), and Old Guard
Group, Inc., a Pennsylvania corporation ("Target"). Acquiror, Merger Sub and
Target are sometimes collectively referred to herein as the "Parties" and
individually as a "Party."

                                    RECITALS

    A. The respective Boards of Directors of Target, Acquiror and Merger Sub
believe it is in the best interests of their respective companies that Target
and Merger Sub combine into a single company through the statutory merger of
Target with and into Merger Sub whereby either Target or Merger Sub will be the
surviving corporation (the "Merger") and, in furtherance thereof, have approved
the Merger.

    B. Target, Acquiror and Merger Sub desire to make certain representations
and warranties and other agreements in connection with the Merger.

    C. Concurrent with the execution of this Agreement and as a material
inducement to Acquiror and Merger Sub to enter into this Agreement, (a) Target
and Acquiror have entered into a Target Option Agreement dated the date hereof
and attached hereto as Exhibit B (the "Target Option Agreement") providing for
the purchase by Acquiror of newly issued shares of Target's common stock in
certain specified circumstances, (b) Acquiror and certain stockholders of Target
(the "Selected Stockholders") have entered into a Voting Agreement dated the
date hereof and attached hereto as Exhibit C (the "Voting Agreement") providing
for (i) an agreement to vote the shares of Target's common stock owned by such
Selected Stockholders to approve the Merger and against any competing proposals,
and (ii) in certain specified circumstances the purchase by Acquiror of
outstanding shares of Target's common stock held by such Selected Stockholders.

    NOW, THEREFORE, in consideration of the covenants and representations set
forth herein, and for other good and valuable consideration, the Parties agree
as follows:

                                   ARTICLE I
                                  DEFINITIONS

    Certain capitalized terms used in this Agreement shall have the meanings
ascribed thereto in Exhibit A attached hereto. References to any federal, state,
local or foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise.
Unless the context otherwise requires, all references to "Sections," "Exhibits"
and "Schedules" shall be deemed to refer to Sections within or Exhibits and
Schedules to this Agreement. All Exhibits and Schedules to this Agreement are
hereby incorporated herein. The word "including" shall mean including without
limitation, and the word "or" shall not be limiting. Unless the context
otherwise requires, any word used in the singular form shall be interpreted as
including the plural form thereof, and vice versa, and any word used in one
gender shall be interpreted as including the other gender, as necessary or
appropriate. Any reference to facts or information "known" to a Party, or words
having similar meaning, shall refer to the conscious awareness of information of
the directors and those responsible officers and employees of such Party and its
Subsidiaries charged with administrative or operational responsibility for such
matters, and which is known or would be known to any one or more of them
following reasonable investigation under the circumstances.

<PAGE>
                                   ARTICLE II
                                   THE MERGER

    2.1  THE MERGER.  At the Effective Time and subject to and upon the terms
and conditions of this Agreement, the Articles of Merger attached hereto as
Exhibit D (the "Certificate of Merger") and the applicable provisions of the
Pennsylvania Business Corporation Law ("Pennsylvania Law") and Ohio General
Corporation Law ("Ohio Law"), Merger Sub shall be merged with and into Target,
the separate corporate existence of Merger Sub shall cease and Target shall
continue as the surviving corporation. Target as the surviving corporation after
the Merger is hereinafter sometimes referred to as the "Surviving Corporation."
Notwithstanding the foregoing or any other provision of this Agreement, at any
time prior to Closing, Acquiror shall have an option (the "Restructuring
Option") to elect that, following the Merger, Target shall be merged with and
into Merger Sub, the separate corporate existence of Target shall cease, and
Merger Sub shall continue as the Surviving Corporation, provided, however, that
exercise of the Restructuring Option shall not have any adverse effect on
(i) the amount of Merger Consideration payable to holders of Target Common
Stock, or (ii) the Tax consequences of the Merger to holders of Target Common
Stock. In the event Acquiror effects the Restructuring Option prior to the
Closing, (i) in lieu of the Certificate of Merger attached as Exhibit D, the
Parties shall execute a Certificate of Merger (as required by and as defined in
Ohio Law and Pennsylvania Law) to effect the Merger of Target into Merger Sub,
such Certificate of Merger shall be deemed the "Certificate of Merger" for all
purposes under this Agreement, (ii) all other provisions of this Agreement
relating to the Surviving Corporation shall be deemed automatically amended to
reflect the Restructuring Option to the extent necessary or appropriate, and
(iii) the Merger Sub shall expressly assume (within the meaning of Treasury
Regulation Section1.461-4(d)(5)(i)) any and all liabilities of Target arising
out of Target's trade or business that Target, but for the economic performance
requirements of Section 461(h) of the Code, would have been entitled to incur as
of the Effective Time.

    2.2  CLOSING; EFFECTIVE TIME.  The closing of the transactions contemplated
hereby (the "Closing") shall take place on a date as soon as reasonably
practicable after the satisfaction or waiver of each of the conditions set forth
in Article VII hereof or at such other date as the Parties agree (the "Closing
Date"). The Closing shall take place at the offices of Bricker & Eckler LLP, 100
South Third Street, Columbus, Ohio 43215, or at such other location as the
Parties agree. In connection with the Closing, the Parties shall cause the
Merger to be consummated by filing the Certificate of Merger and any other
required information with the Secretary of State of each of the States of
Pennsylvania and Ohio (the time of such filing being the "Effective Time").

    2.3  EFFECT OF THE MERGER.  At the Effective Time, the effect of the Merger
shall be as provided in this Agreement, the Certificate of Merger and the
applicable provisions of Pennsylvania Law and Ohio Law. Without limiting the
generality of the foregoing, and subject thereto, at the Effective Time, all the
property, rights, privileges, powers and franchises of Target and Merger Sub
shall vest in the Surviving Corporation, and all debts, liabilities and duties
of Target and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

    2.4  ARTICLES OF INCORPORATION: BYLAWS OR CODE OF REGULATIONS.  (a) At the
Effective Time, the Articles of Incorporation of Target, as in effect
immediately prior to the Effective Time, shall be the Articles of Incorporation
of the Surviving Corporation until thereafter amended as provided by
Pennsylvania Law and the Surviving Corporation's Articles of Incorporation.
Notwithstanding the foregoing, if Acquiror elects the Restructuring Option prior
to the Closing, the Articles of Incorporation of Merger Sub, as in effect
immediately prior to the Effective Time, shall be the Articles of Incorporation
of the Surviving Corporation until thereafter amended as provided by Ohio Law
and the Surviving Corporation's Articles of Incorporation; provided, however,
that Article I of the Articles of Incorporation of the Surviving Corporation
shall be amended to read as follows: "The name of the corporation is Old Guard
Group, Inc."

                                      A-2
<PAGE>
    (b) The Bylaws of Target, as in effect immediately prior to the Effective
Time, shall be the Bylaws of the Surviving Corporation until thereafter amended
in accordance therewith; provided, however, that if Acquiror elects the
Restructuring Option prior to the Closing, the Code of Regulations of Merger
Sub, as in effect immediately prior to the Effective Time, shall be the Code of
Regulations of the Surviving Corporation until thereafter amended in accordance
therewith.

    2.5  DIRECTORS AND OFFICERS.  At the Effective Time the directors of Target
shall be the initial directors of the Surviving Corporation, until their
respective successors are duly elected or appointed and qualified, subject to
the effect of Section 7.3(j); provided, however, if Acquiror elects the
Restructuring Option prior to the Closing, the directors of Merger Sub shall be
the initial directors of the Surviving Corporation, until their respective
successors are duly elected or appointed and qualified. The officers of Target
shall be the initial officers of the Surviving Corporation, until their
respective successors are duly elected or appointed and qualified.

    2.6  CONVERSION OF TARGET COMMON STOCK.

    (a) At the Effective Time, subject to Section 2.14, each share of common
stock, no par value, of Target ("Target Common Stock"), issued and outstanding
immediately prior to the Effective Time (other than Dissenting Shares and any
shares of Target Common Stock to be canceled pursuant to Section 2.13), will be
canceled and extinguished and converted automatically into the right to receive
cash in an amount equal to $12.00 per share, as such amount may be adjusted
pursuant to the provisions of Section 2.9 (the "Merger Consideration").

    (b) On and after the Effective Time, holders of certificates (other than
holders of Dissenting Shares) which immediately prior to the Effective Time
represented outstanding shares of Target Common Stock (the "Certificates") shall
cease to have any rights as stockholders of Target, except the right to receive
the Merger Consideration for each such share of Target Common Stock held by
them.

    2.7  OPTIONS AND TARGET STOCK OPTION PLANS.  All options, warrants or
similar rights (including related stock appreciation rights, if any) (each an
"Option") issued, awarded or granted pursuant to any plan, agreement or
arrangement of Target or any of its Subsidiaries and entitling the holder
thereof to purchase shares of Target Common Stock or any other capital stock of
Target or any of its Subsidiaries (the "Target Stock Option Plans") shall be
terminated at or prior to the Effective Time, either automatically pursuant to
the terms thereof or by execution of an agreement referred to in this
Section 2.7, and each holder of a terminated Option with an exercise price per
share less than the Merger Consideration shall be entitled to receive, in
consideration for the termination of such Option, an amount in cash (less
applicable withholding Taxes) equal to the excess of the Merger Consideration
over the exercise price per share for each Option so terminated. Each holder of
a terminated Option with an exercise price per share greater than the Merger
Consideration shall receive no consideration for termination thereof. The total
consideration to be paid for the termination of all Options pursuant to this
Section 2.7 is hereinafter referred to as the "Option Termination
Consideration." At least five (5) business days prior to the Closing,
(x) Target shall deliver to Acquiror agreements (in a form reasonably acceptable
to Acquiror) executed by each director and officer of Target and any Subsidiary
thereof holding an Option acknowledging that the payment made pursuant to this
Section 2.7 is being made in full satisfaction of such Person's rights under the
applicable Target Stock Option Plans and any Option awards granted thereunder,
and (y) Target shall use commercially reasonable efforts to obtain executed
agreements of the type described in clause (x) from each other holder of an
Option to purchase shares of Target Common Stock awarded under any Target Stock
Option Plans. At or immediately prior to the Effective Time, Target shall pay,
or cause to be paid, to each holder of a terminated Option with an exercise
price less than the Merger Consideration, the Option Termination Consideration
to which such holder is entitled to receive pursuant to such holder's agreement
described in clauses (x) and (y) above and this Section 2.7.

                                      A-3
<PAGE>
    2.8  CAPITAL STOCK OF MERGER SUB CONVERTED.  At the Effective Time, each
share of common stock, no par value, of Merger Sub ("Merger Sub Common Stock")
issued and outstanding immediately prior to the Effective Time shall be
converted into 300,000 shares of common stock, no par value, of the Surviving
Corporation, such that the Surviving Corporation shall be a wholly owned
subsidiary of Acquiror. On and after the Effective Time, holders of certificates
which immediately prior to the Effective Time represented outstanding shares of
Merger Sub Common Stock shall represent such number of shares of common stock of
the Surviving Corporation, multiplied by 300,000. Notwithstanding the foregoing,
if Acquiror elects the Restructuring Option prior to the Closing, each share of
Merger Sub Common stock issued and outstanding immediately prior to the
Effective Time shall remain issued and outstanding and be unaffected by the
Merger, and each stock certificate of Merger Sub representing outstanding shares
of Merger Sub Common Stock shall evidence ownership of such shares of common
stock of the Surviving Corporation.

    2.9  ADJUSTMENTS TO MERGER CONSIDERATION.  The per share amount of the
Merger Consideration specified in Section 2.6 shall be adjusted to reflect fully
the effect of any stock split, reverse split, stock dividend (including any
dividend or distribution of securities convertible into Target Common Stock),
reorganization, recapitalization or other like change with respect to Target
Common Stock occurring after the date hereof and prior to the Effective Time.

    2.10  CANCELLATION OF TARGET COMMON STOCK OWNED BY ACQUIROR OR TARGET.  At
the Effective Time, all shares of Target Common Stock owned by Target as
treasury stock and each share of Target Common Stock owned by any direct or
indirect wholly owned Subsidiary of Target immediately prior to the Effective
Time shall be canceled and extinguished without any conversion thereof.

    2.11  SURRENDER OF CERTIFICATES.

    (a)  EXCHANGE AGENT.  American Stock Transfer & Trust Company, or such other
bank or trust company selected by Acquiror and approved by Target (the approval
of which shall not be unreasonably withheld by Target), shall act as exchange
agent (the "Exchange Agent") in the Merger.

    (b)  ACQUIROR TO PROVIDE CASH.  Promptly after the Effective Time, Acquiror
shall deposit with the Exchange Agent sufficient cash to make all cash payments
to be made pursuant to Section 2.6. All deposits of cash with the Exchange Agent
pursuant to this Section 2.11, together with any earnings thereon, are referred
to as the "Exchange Fund." The Exchange Fund may be invested in short-term
investment-grade debt instruments as directed by Acquiror and shall not be used
for any purpose except as provided in this Agreement. Any risk of loss with
respect to the Exchange Fund shall be borne by Acquiror.

    (c)  EXCHANGE PROCEDURES.  Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each holder of record of a certificate
or certificates which immediately prior to the Effective Time represented
outstanding shares of Target Common Stock (the "Certificates"), (i) a letter of
transmittal (which shall specify that delivery shall be effected, and risk of
loss and title to the Certificates shall pass, only upon receipt of the
certificates by the Exchange Agent, and shall be in such form and have such
other provisions as Acquiror may reasonably specify), and (ii) instructions for
use in effecting the surrender of the Certificates in exchange for cash. Upon
surrender of a Certificate for cancellation to the Exchange Agent or to such
other agent or agents as may be appointed by Acquiror, together with such letter
of transmittal, duly completed and validly executed in accordance with the
instructions thereto, and such other customary documents as may be reasonably
required pursuant to such instructions, the holder of such Certificate (other
than a holder of Dissenting Shares) shall be entitled to receive in exchange
therefor the Merger Consideration to which such holder shall have become
entitled pursuant to Section 2.6 and the Certificate so surrendered shall
forthwith be canceled. No interest will be paid or accrued on any amount payable
upon due surrender of the Certificates. Any interest or other income earned by
the Exchange Fund shall be for the account of Acquiror. Subject to Pennsylvania
Law and the provisions of this Agreement in the case of Dissenting Shares, until
so

                                      A-4
<PAGE>
surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of Target Common Stock will be deemed from and after the
Effective Time, for all corporate purposes, to evidence solely the right to
receive, upon surrender of such Certificate, the Merger Consideration with
respect to the shares of Target Common Stock represented thereby.

    (d)  FAILURE OF TARGET STOCKHOLDERS TO DELIVER CERTIFICATES.  Any portion of
the Exchange Fund which remains unclaimed by holders of Target Common Stock for
60 days after the Effective Time shall be delivered to Acquiror, and the holders
of Target Common Stock shall thereafter look only to Acquiror for payment of
their claims for the Merger Consideration in respect of their shares of Target
Common Stock. If any Certificates shall not have been surrendered prior to two
years after the Effective Time (or immediately prior to such earlier date on
which any payment in respect thereof would otherwise escheat or become the
property of any governmental unit or agency), the payment in respect of such
Certificates shall, to the extent permitted by applicable law, become the
property of Acquiror, free and clear of all claims or interest of any Person
previously entitled thereto.

    (e)  NO LIABILITY.  Notwithstanding anything to the contrary in this
Agreement, neither the Exchange Agent, the Surviving Corporation, nor any other
Party shall be liable to any Person for any amount properly paid to a public
official pursuant to any applicable abandoned property, escheat or similar law.

    (f)  TAX WITHHOLDING.  Acquiror or the Exchange Agent shall be entitled to
deduct and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of a Certificate surrendered for the Merger
Consideration such amount as Acquiror or the Exchange Agent is required to
deduct and withhold with respect to the making of such payment under the
Internal Revenue Code of 1986, as amended (the "Code"), or any provision of any
state, local or foreign Tax law. To the extent that amounts are so deducted and
withheld, such amounts shall be treated for all purposes of this Agreement as
having been paid to the holder thereof.

    2.12  NO FURTHER OWNERSHIP RIGHTS IN TARGET COMMON STOCK.  All cash
transmitted upon the surrender for exchange of shares of Target Common Stock in
accordance with the terms hereof shall be deemed to have been given in full
satisfaction of all rights pertaining to such shares of Target Common Stock, and
there shall be no further registration of transfers on the records of the
Surviving Corporation of shares of Target Common Stock which were outstanding
immediately prior to the Effective Time. If, after the Effective Time,
Certificates are presented to the Surviving Corporation for any reason, they
shall be canceled and exchanged as provided in this Article II.

    2.13  DISSENTING SHARES.

    (a)  STATUS OF DISSENTING SHARES.  Notwithstanding the provisions of
Section 2.6 or any other provision of this Agreement to the contrary, shares of
Target Common Stock that are issued and outstanding immediately prior to the
Effective Time and are held by stockholders who have not voted such shares in
favor of the Merger and the approval and adoption of this Agreement and who
shall have properly demanded appraisal of such shares of Target Common Stock
(the "Dissenting Shares") in accordance with Title 15, Article B, Chapter 19,
Subchapter C, Section 1930 of the Pennsylvania Law or any successor or
replacement provision (the "Dissenters Rights Law") shall not be converted into
the right to receive the Merger Consideration at or after the Effective Time,
unless and until the holder of such Dissenting Shares shall have failed to
perfect or shall have effectively withdrawn or lost such right to appraisal and
payment under Pennsylvania Law. If a holder of Dissenting Shares shall have so
failed to perfect or shall have effectively withdrawn or lost such right to
appraisal and payment, then, as of the Effective Time or the occurrence of such
event, whichever last occurs, such holder's Dissenting Shares shall be converted
into and represent solely the right to receive the Merger Consideration, without
any interest thereon, as provided in Section 2.6.

                                      A-5
<PAGE>
    (b)  DIRECTION OF APPRAISAL PROCEEDINGS.  Target shall give Acquiror
(i) prompt notice of any written demands for appraisal, withdrawals of demands
for appraisal and any other instruments served pursuant to the Dissenters Rights
Law which are received by Target, and (ii) the opportunity to direct all
negotiations and proceedings with respect to demands for appraisal under
Pennsylvania Law. Target will not voluntarily make any payment with respect to
any demands for appraisal and will not, except with the prior written consent of
Acquiror, settle or offer to settle any such demands.

    2.14  LOST, STOLEN OR DESTROYED CERTIFICATES.  In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange therefor, upon the making of an affidavit of that fact by the holder
thereof, the Merger Consideration with respect to the shares of Target Common
Stock represented thereby as may be required pursuant to Section 2.6; provided,
however, that Acquiror may, in its discretion and as a condition precedent to
the issuance thereof, require the owner of such lost, stolen or destroyed
Certificates to deliver a bond in such sum as it may reasonably direct as
indemnity against any claim that may be made against Acquiror, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.

    2.15  TAKING OF NECESSARY ACTION: FURTHER ACTION.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the

                                  ARTICLE III
                    REPRESENTATIONS AND WARRANTIES OF TARGET

    Target represents and warrants to Acquiror and Merger Sub that the
statements in this Article III are true and correct, except as set forth in the
disclosure schedule delivered by Target to Acquiror and Merger Sub as of this
date and acknowledged by the Parties (the "Target Disclosure Schedule"). The
mere listing (or inclusion of a copy) of a document or other item shall not be
deemed adequate to disclose an exception to a representation or warranty made
herein (unless the representation or warranty has to do with the existence of
the document or other item itself). The Target Disclosure Schedule is arranged
in paragraphs corresponding to the lettered and numbered sections and schedules
contained in or referred to in this Article III. The representations and
warranties of Target contained in this Article III and elsewhere in this
Agreement, or in the Target Disclosure Schedule or any other document delivered
pursuant to or contemplated by this Agreement, shall not be affected or deemed
waived by reason of the fact that Acquiror, Merger Sub and/or their
representatives knew or should have known that any such representation or
warranty is or might be untrue or inaccurate in any respect.

    3.1  ORGANIZATION, STANDING AND POWER.  Target and each of Target's
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization, has all requisite
corporate power and authority to own properties and to carry on business as now
being conducted and as proposed to be conducted and is duly qualified to do
business and is in good standing in each jurisdiction where its ownership or
leasing of property or the conduct of its business requires it to be so
qualified, except where the failure to be so qualified would not have a Material
Adverse Effect on Target. Each Target Subsidiary which is engaged in the
business of insurance has valid and subsisting licenses to conduct the insurance
business conducted by such Subsidiary. All of Target's Subsidiaries are listed
on Schedule 3.1, identifying thereon (with respect to each Subsidiary which is
an insurance company) its state of domicile and the states in which it is
licensed to conduct an insurance business. Except as disclosed on Schedule 3.1,
Target does not directly or indirectly own any equity or similar interest in, or
any interest convertible or exchangeable or exercisable for, any equity or

                                      A-6
<PAGE>
similar interest constituting in excess of five percent (5%) of the ownership
in, any other corporation, partnership, joint venture or other business
association or entity. Target has delivered to Acquiror a true and correct copy
of the Articles of Incorporation, as amended (the "Articles of Incorporation")
of Target, and the Bylaws, as amended (the "Bylaws") of Target, and the Articles
of Incorporation and Bylaws or other organizational documents, as applicable, of
each of its Subsidiaries, each as amended to date. Target is not in violation of
any of the provisions of the Articles of Incorporation or Bylaws, and no such
Subsidiary is in violation of any provisions of its equivalent organizational
documents. Except as set forth in Schedule 3.1, Target owns beneficially and of
record all outstanding shares of capital stock of each of its Subsidiaries, and
all such shares of capital stock are duly authorized, validly issued, fully paid
and nonassessable. All outstanding shares of capital stock of each such
Subsidiary are owned by Target free and clear of any charge, mortgage, pledge,
security interest, restriction, claim, lien, or encumbrance (collectively,
"Liens"). Except as set forth on Schedule 3.1, there are no outstanding
subscriptions, options, warrants, puts, calls, rights, exchangeable or
convertible securities, voting agreements or proxies, or other commitments or
agreements of any character relating to the issued or unissued capital stock or
other securities of any such Subsidiary, or otherwise obligating Target or any
such Subsidiary to issue, transfer, sell, purchase, redeem or otherwise acquire
any such securities.

    3.2  CAPITAL STRUCTURE.  The authorized capital stock of Target consists of
15,000,000 shares of Target Common Stock, with no par value, and 5,000,000
shares of preferred stock, with no par value. As of the close of business on
April 30, 2000, 3,708,571 shares of Target Common Stock (excluding treasury
shares) were issued and outstanding, no shares of preferred stock were issued or
outstanding, and 548,756 shares of Target Common Stock were held in treasury.
All outstanding shares of Target Common Stock are duly authorized, validly
issued, fully paid and nonassessable and are free and clear of any Liens other
than Liens created by or imposed upon the holders thereof, and are not subject
to preemptive rights or rights of first refusal created by statute, the Articles
of Incorporation or Bylaws of Target, or any agreement to which Target is a
party or by which it is bound. Target has reserved 588,687 shares of Target
Common Stock for issuance to employees, directors and certain insurance agents
of Target's insurance company Subsidiaries pursuant to the Target Stock Option
Plans and the Management Recognition Plan of Target dated August 19, 1997 (the
"MRP"), of which 50,167 shares have been issued pursuant to valid Option
exercises, 163,547 shares have been issued pursuant to valid MRP grants, and
231,515 shares remain subject to outstanding and unexercised Options under the
Target Stock Option Plans, all of which Options shall become fully vested and
available for exercise at or upon consummation of the Merger. All shares granted
under the MRP have been issued and will automatically fully vest upon
consummation of the Merger. Target has not issued or granted additional Options
under the Target Stock Option Plans, and has not made additional grants under
the MRP. Other than rights under this Agreement, the Target Option Agreement and
the MRP, and other than Options outstanding under the Target Stock Option Plans
in the amounts reserved for as set forth above, there are no other Options,
commitments or agreements of any character to which Target is a party or by
which it is bound obligating Target to issue, deliver, sell, repurchase or
redeem, or cause to be issued, delivered, sold, repurchased or redeemed, any
shares of capital stock of Target or obligating Target to grant, extend,
accelerate the vesting of, change the price of, or otherwise amend or enter into
any such Option, warrant, call, right, commitment or agreement. All issuances of
securities by Target and its Subsidiaries, including all Target Common Stock,
since their respective dates of incorporation complied with all applicable
federal and state securities laws, and all registrations and filings required
thereby have been timely made by or on behalf of the issuer thereof. Except as
set forth on Schedule 3.2, there are no Contracts, commitments or understandings
relating to the voting, purchase or sale of any capital stock of Target or any
of its Subsidiaries (i) between or among Target and any of its stockholders or
any third party, and (ii) to the best of Target's knowledge, between or among
any of Target's stockholders or any third party. True and complete copies of all
Target Stock Option Plans and the MRP, and all agreements and instruments
relating to or issued thereunder, are listed on

                                      A-7
<PAGE>
Schedule 3.2 and have been provided to Acquiror. The Target Stock Option Plans
and the MRP, such agreements and instruments relating to or issued thereunder,
have not been amended, modified or supplemented, and there are no agreements to
amend, modify or supplement such plans, agreements or instruments, in any case
from the form made available to Acquiror. Schedule 3.2 includes a complete list
of all holders of outstanding Options under the Target Stock Option Plans and a
complete list of all grants under the MRP, including the number of shares of
Target Common Stock subject to each such Option or MRP grant, the exercise or
vesting schedule, the exercise price per share and the term of each such Option
or grant.

    3.3  AUTHORITY.  Target has all requisite corporate power and authority to

Agreement and the Target Option Agreement and the consummation of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary corporate action on the part of Target, subject only to the approval
of the Merger by Target's stockholders as contemplated by Section 7.1(a). Both
this Agreement and the Target Option Agreement have been duly executed and
delivered by Target and constitute valid and binding obligations of Target
enforceable against Target in accordance with their terms, except as
enforceability may be limited by bankruptcy and other laws affecting the rights
and remedies of creditors generally and general principles of equity. Except as
described on Schedule 3.3, the execution and delivery of this Agreement and the
Target Option Agreement by Target do not or will not, as the case may be, and
the consummation of the transactions contemplated hereby and thereby will not,
conflict with, or result in any violation of, or default under (with or without
notice or lapse of time, or both), or give rise to a right of termination,
amendment, cancellation or acceleration of any obligation or loss of any benefit
under (i) any provision of the Articles of Incorporation or Bylaws of Target or
equivalent organizational documents of any of Target's Subsidiaries, as amended,
(ii) any Contract to which Target or any of its Subsidiaries is a party or by
which any of them is bound, or (iii) any permit, concession, franchise, license,

which Target or any of its Subsidiaries or any of their properties or assets is
subject or bound or that give rise to any Lien, except where such conflict,
violation, default, termination, cancellation or acceleration with respect to
the foregoing provisions of (iii) would not have had and could not reasonably be
expected to have a Material Adverse Effect on Target. No consent, approval,
order or authorization of, or registration, declaration or filing with, any
Governmental Entity is required by or with respect to Target or any of its

Securities Act, and none of the Target SEC Documents contained (or will contain)
any untrue statement of a material fact or omitted (or will omit) to state a
material fact required to be stated therein or necessary to make the statements
made therein, in light of the circumstances in which they were made, not
misleading. Target has provided to Acquiror the audited financial statements,
including the footnotes thereto, of Target and its Subsidiaries for the fiscal

promulgated by the SEC). The Target Financial Statements fairly present (or will
fairly present) the consolidated financial condition, operating results, cash
flows and changes in stockholders' equity of Target and its Subsidiaries at the
dates and during the periods indicated therein (subject, in the case of
unaudited statements, to normal, recurring year-end adjustments that were or are

which it is bound; (vi) any amendment or change to the Articles of Incorporation
or Bylaws of Target or organizational documents of any of its Subsidiaries; or

    3.13  TAXES.  Target and its Subsidiaries, and any consolidated, combined,
unitary or aggregate group for Tax purposes of which Target or any of its
Subsidiaries is or has been a member, have timely filed all Tax Returns required
to be filed by them and have paid (or withheld and paid) all Taxes owed by (or
required to be withheld and paid by) Target and its Subsidiaries (whether or not
shown on any Tax Return), unless appropriately contested thereby and accrued in
the balance sheet contained in the Target 1999 Audited Statements. All such Tax
Returns are complete and accurate in all respects and properly reflect the Taxes
of Target and its Subsidiaries for the periods covered thereby. Target has

                                      A-13
<PAGE>
provided adequate accruals in accordance with GAAP in the Target Financial
Statements for any Taxes that were not paid as of the date of such financial
statements, whether or not shown as being due on any Tax Return. Target and its
Subsidiaries are not delinquent in the payment of any Tax, assessment or similar
governmental charge. Neither Target nor any of its Subsidiaries has received any
notice that any Tax deficiency has been asserted against Target or any of its
Subsidiaries, and there is no threat of such assertion. There is no unpaid
assessment, proposal for additional Taxes, deficiency or delinquency in the
payment of any Tax that could be asserted by any Tax Authority. Neither Target
nor any of its Subsidiaries has violated any applicable federal, state, local or
foreign Tax law in any respect. Except as disclosed in the SEC Documents and the
Target 1999 Audited Statements, (i) no claim for Taxes has become a Lien against
the property of Target or any of its Subsidiaries or is being asserted against
Target or any of its Subsidiaries, (ii) no action, suit, proceeding,
investigation, claim or audit has formally commenced and no written notification
has been given that such audit or other proceeding is pending or threatened with
respect to Target or any of its Subsidiaries in respect of any Tax, (iii) no
extension or waiver of the statute of limitations on the assessment or
collection of any Tax has been granted by Target or any of its Subsidiaries and
is currently in effect, and (iv) there is no agreement, Contract or arrangement
to which Target or any of its Subsidiaries is a party that may result in the
payment of any amount that would not be deductible by reason of Section 280G,
162 or 404 of the Code. Target has not been and will not be required to include
any adjustment in Taxable income for any Tax period (or portion thereof)
pursuant to Section 481 or 263A of the Code or any comparable provision under
state or foreign Tax laws as a result of transactions, events or accounting
methods employed prior to the Merger. Except as set forth on Schedule 3.13,
neither Target nor any of its Subsidiaries is a party to any tax sharing or tax
allocation agreement, nor does Target or any of its Subsidiaries owe any amount
under any such agreement. No consent to the application of Section 341(f)(2) of
the Code has been filed with respect to Target or any of its Subsidiaries. All
Taxes that Target or any of its Subsidiaries is or was required to withhold or
collect have been duly withheld or collected and, to the extent required, have
been paid to the proper Governmental Entity, Tax Authority or other Person.
Target and its Subsidiaries will not be required to include any amount in
Taxable income for any Taxable period (or portion thereof) ending after the
Closing Date as a result of a change in the method of accounting for a Taxable
period ending prior to the Closing Date, any "closing agreement" as described in
Section 7121 of the Code (or any corresponding provision of state, local, or
foreign tax laws) entered into prior to the Closing Date, any sale reported on
the installment method that occurred prior to the Closing Date, or any Taxable
income from "excess loss accounts" or "intercompany transactions" as defined in
the Code or the applicable Treasury Regulations (or any corresponding provision
of state, local or foreign tax laws). The United States federal, state and
foreign Tax Returns of Target and its Subsidiaries have been audited by the IRS
or relevant state or foreign Tax Authorities or are closed by the applicable
statute of limitations for all taxable years set forth on Schedule 3.13.
Schedule 3.13 sets forth a reasonably detailed description of the nature of any
pending audit relating to Taxes. No claim has been made by a Tax Authority in
any jurisdiction in which Target or any of its Subsidiaries does not file Tax
Returns that Target or any of its Subsidiaries is required to file Tax Returns
in such jurisdiction and, to the knowledge of Target and its Subsidiaries, no
Tax Authority could reasonably make any such claim.

    3.14  EMPLOYEE BENEFIT PLANS.

    (a) Schedule 3.14 lists (i) all employee benefit plans (as defined in
Section 3(3) of the Employee Retirement Income Security Act of 1974, as amended
("ERISA")) and related trusts which are maintained or contributed to by Target
or any of its Subsidiaries or with respect to which Target or any of its
Subsidiaries has any liability or obligation to contribute, (ii) each loan to a
non-officer employee or former employee of Target or any of its Subsidiaries,
loans to officers and directors of Target or any of its Subsidiaries and any
stock option, stock purchase, phantom stock, stock appreciation right,
severance, sabbatical, employee relocation, cafeteria benefit (Code
Section 125) or dependent care (Code Section 129), or accident insurance plans,
programs or arrangements benefiting employees or former employees of Target or
any of its Subsidiaries, (iii) all bonus, profit sharing, savings, deferred
compensation or incentive plans, programs or arrangements benefiting employees
or former employees of Target or any of its Subsidiaries, (iv) other fringe or
employee benefit plans, programs or arrangements that apply to management and
other employees of Target or any of its Subsidiaries, and (v) any current or
former employment or executive compensation or severance agreements, written or
otherwise, as to which unsatisfied obligations of Target or any of its
Subsidiaries of greater than $25,000 remain for the benefit of, or relating to,
any present or former employee, consultant or director of Target or any of its
Subsidiaries (together, the "Target Employee Plans").

    (b) Target has furnished to Acquiror a copy of each of the Target Employee
Plans and related plan documents (including trust documents, insurance policies
or contracts with third party administrators, actuaries, investment managers,
consultants and all independent contractors related to such Target Employee
Plans, employee booklets, employment manuals, policy manuals, summary plan
descriptions and other authorizing documents, and any material employee
communications relating thereto), the most recent actuarial report, where
applicable, and has, with respect to each Target Employee Plan which is subject
to ERISA reporting requirements, provided copies of the Form 5500 reports filed
for the last three plan years. Any Target Employee Plan intended to be qualified
under Section 401(a) of the Code has either obtained from the Internal Revenue
Service a favorable determination letter as to its qualified status under the
Code, including all amendments to the Code effected by the Tax Reform Act of
1986 and subsequent legislation, or has applied to the Internal Revenue Service
for such a determination letter prior to the expiration of the requisite period
under applicable Treasury Regulations or Internal Revenue Service pronouncements
in which to apply for such determination letter and to make any amendments
necessary to obtain a favorable determination. Target has furnished Acquiror
with the most recent Internal Revenue Service determination letter issued with
respect to each such Target Employee Plan, and nothing has occurred since the
issuance of each such letter which would reasonably be expected to cause the
loss of the tax qualified status of any Target Employee Plan subject to Code
Section 401(a). Target has furnished Acquiror with all registration statements
and prospectuses prepared in connection with each Target Employee Plan.

    (c) (i) No Target Employee Plan promises or provides retiree medical or
other retiree welfare benefits to any Person, except as required by applicable
law; (ii) there has been no "prohibited transaction," as such term is defined in
Section 406 of ERISA and Section 4975 of the Code, with respect to any Target
Employee Plan; (iii) each Target Employee Plan has been administered in
accordance with its terms and in compliance with the requirements prescribed by
any and all statutes, rules and regulations (including ERISA and the Code), and
Target and each of its Subsidiaries have performed all obligations required to
be performed by them under, are not in any material respect in default under or
violation of, and have no knowledge of any default or violation by any other
party to, and are otherwise in full compliance with ERISA, the Code and other
applicable laws with respect to any of the Target Employee Plans; (iv) neither
Target nor any of its Subsidiaries is subject to any liability or penalty under
Sections 4971 through 4980E of the Code or Title I of ERISA with respect to any
of the Target Employee Plans; (v) all contributions required to be made by
Target or any of its Subsidiaries to any Target Employee Plan have been made on
or before their due dates and the full

                                      A-15
<PAGE>
amount required has been accrued for contributions to each Target Employee Plan
for the current plan years; (vi) with respect to each Target Employee Plan, no
"reportable event" within the meaning of Section 4043 of ERISA (excluding any
such event for which the thirty (30) day notice requirement has been waived
under the regulations to Section 4043 of ERISA) nor any event described in
Section 4062, 4063 or 4041 of ERISA has occurred; (vii) no Target Employee Plan
is covered by, and neither Target nor any of its Subsidiaries nor any trade or
business (whether or not incorporated) which is, or at any time within the
six-year period preceding the date of this Agreement, was treated as a single
employer with Target (an "ERISA Affiliate") within the meaning of
Section 414(b), (c), (n) or (o) of the Code, maintains or contributes to or at
any time within the six-year period preceding the date of this Agreement
maintained or contributed to or had an obligation to contribute to any employee
benefit plan covered by or has incurred or expects to incur any liability under
Part 3 of Subtitle B of Title I of ERISA, Title IV of ERISA or Section 412 of
the Code; (viii) each Target Employee Plan can be amended, terminated or
otherwise discontinued after the Effective Time in accordance with its terms,
without liability to Acquiror and without any additional accrual on the books of
Target or any of its Subsidiaries; and (ix) no Target Employee Plan promises or
provides benefits to any of Target's or its Subsidiaries' independent
contractors or subcontractors. With respect to each Target Employee Plan subject
to ERISA as either an employee pension plan within the meaning of Section 3(2)
of ERISA or an employee welfare benefit plan within the meaning of Section 3(1)
of ERISA, Target has prepared in good faith and timely filed all requisite
governmental reports (which were true and correct in all material respects as of
the date filed) and has properly and timely filed and distributed or posted all
notices and reports to employees required to be filed, distributed or posted
with respect to each such Target Employee Plan. No suit, administrative
proceeding, action or other litigation has been brought, or to the knowledge of
Target or its Subsidiaries is threatened, against or with respect to any such
Target Employee Plan, including any audit or inquiry by the IRS or United States
Department of Labor. No payment or benefit which will or may be made by Target
or any of its Subsidiaries to any employee will be characterized as an "excess
parachute payment" within the meaning of Section 280G(b)(1) of the Code.

    (d) The consummation of the transactions contemplated by this Agreement will
not (i) entitle any current or former employee or other service provider of
Target, any of its Subsidiaries or any other ERISA Affiliate to severance
benefits or any other payment, except as expressly provided in this Agreement,
or (ii) accelerate the time of payment or vesting, or increase the amount of
compensation due any such employee or service provider.

    (e) There has been no amendment to, written interpretation or announcement
(whether or not written) by Target or any of its Subsidiaries relating to, or
change in participation or coverage under, any Target Employee Plan which would
materially increase the expense of maintaining such Plan above the level of
expense incurred with respect to that Plan as reflected in the Target Financial
Statements for the most recently completed fiscal year.

    (f) Target's Employee Stock Ownership Plan (the "ESOP") is an "employee
stock ownership plan" within the meaning of Section 4985(e)(7) of the Code and
is qualified under Section 401(a) of the Code. The ESOP has been duly
constituted in accordance with the Trust Agreement dated as of January 1, 1997,
as amended (the "Trust Agreement"), by and between Target and Bank of Lancaster,
N. A. (the "Trustee"), is validly existing and is Tax-exempt under
Section 501(a) of the Code. Since January 1, 1997, the ESOP has been operated in
substantial compliance with terms of the Trust Agreement and the requirements of
ERISA and the Code, and no Person or Governmental Entity has made any claim or
assertion to the contrary, and no basis exists for any such claim or assertion.
The ESOP has the requisite power and authority to own its properties and assets.
The execution, delivery and performance of this Agreement by Target will not
involve any transaction which is subject to the prohibitions of Section 406 of
ERISA for which there is no exemption and will not otherwise constitute

                                      A-16
<PAGE>
a violation by the ESOP of, or give rise to any liability under, any other
provision of Title I of ERISA or Section 4975 of the Code.

    3.15  CERTAIN AGREEMENTS AFFECTED BY THE MERGER.  Except as set forth on
Schedule 3.15, neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will (i) result in any
payment (including severance, unemployment compensation, golden parachute, bonus
or otherwise) becoming due to any director or employee of Target or any of its
Subsidiaries, (ii) materially increase any benefits otherwise payable by Target,
or (iii) result in the acceleration of the time of payment or vesting of any
such benefits.

    3.16  EMPLOYEES AND INSURANCE AGENTS.  (a) Schedule 3.16 sets forth
(i) information regarding (including copies of Contracts with) all managing
general agents with underwriting authority on behalf of Target's Subsidiaries,
and (ii) names, annual rates of salary, bonus, profit-sharing, incentive
compensation, employee benefits and other material compensation of all present
officers, directors, employees, agents (including insurance agents) and
independent contractors of Target and its Subsidiaries (other than employees of
Target or its Subsidiaries with aggregate compensation of less than $40,000
reported on their 1999 Forms W-2 as reported to the Internal Revenue Service).
Schedule 3.16 also sets forth all loans and advances (other than routine travel
advances to be repaid or formally accounted for within thirty days and reflected
on the books of Target) made by Target or any of its Subsidiaries to employees
or agents (including insurance agents) since the Target Balance Sheet Date.
Target and its Subsidiaries are in compliance in all material respects with all
applicable laws and regulations respecting employment, discrimination in
employment, terms and conditions of employment, wages, hours and occupational
safety and health and employment practices, and is not engaged in any unfair
labor practice. Target and its Subsidiaries have withheld all amounts required
by law or by Contract to be withheld from the wages, salaries and other payments
to employees; and are not liable for any arrears of wages or any Taxes or any
penalty for failure to comply with any of the foregoing. Target and its
Subsidiaries are not liable for any material payment to any trust or other fund
or to any Governmental Entity with respect to unemployment compensation
benefits, social security or other benefits or obligations for employees (other
than routine payments to be made in the normal course of business and consistent
with past practice). There are no pending claims against Target or any of its
Subsidiaries for any material amounts under any workers compensation plan or
policy or for long term disability. Neither Target nor any of its Subsidiaries
has any obligations under COBRA with respect to any former employees or
qualifying beneficiaries thereunder, except for obligations that are not
material in amount. There are no controversies pending or, to the knowledge of
Target or any Subsidiary, threatened, between Target or any of its Subsidiaries
and any of their respective employees, which controversies have or would
reasonably be expected to result in an action, suit, proceeding, claim,
arbitration or investigation by or before any Governmental Entity. Neither
Target nor any of its Subsidiaries is a party to any collective bargaining
agreement or other labor union contract, nor does Target or any of its
Subsidiaries have knowledge of any activities or proceedings of any labor union
to organize any such employees. To the knowledge of Target and its Subsidiaries,
no employees of Target or any of its Subsidiaries are in material violation of
any term of an employment contract, patent disclosure agreement, noncompetition
agreement, or restrictive covenant to a former employer relating to the right of
any such employee to be employed by Target or any of its Subsidiaries because of
the nature of the business conduced or presently proposed to be conducted by
Target or any of its Subsidiaries or to the use of trade secrets or proprietary
information of others.

    (b) Target and its Subsidiaries conduct their insurance business solely
through the American independent agency system, and none of them is engaged in
any direct sales of insurance products to customers by way of the internet or
any other direct-writing distribution arrangement. Target's relationships with
its independent agents can reasonably be characterized as good, and no agent (or
group of agents) which accounted for more than one percent (1%) of the insurance
premium of Target and its Subsidiaries during the fiscal year ended
December 31, 1999, has indicated that it will

                                      A-17
<PAGE>
discontinue or materially decrease its level of business written with any of
Target's Subsidiaries, whether as a result of the Merger or otherwise, and
neither Target nor any of its Subsidiaries has any reason to believe that any
such agent will discontinue or materially decrease its business written with
Target's Subsidiaries. Schedule 3.16 identifies each managing general agent
engaged by any Target Subsidiary in its business of insurance and the nature of
the business relationship therewith.

    3.17  INTERESTED PARTY TRANSACTIONS.  Except as disclosed in the Target SEC
Documents, (i) neither Target nor any of its Subsidiaries is indebted to any
director or officer of Target or any of its Subsidiaries (except for amounts due
as normal salaries and bonuses and in reimbursement of ordinary expenses),
(ii) no such Person is indebted to Target or any of its Subsidiaries, and
(iii) there are no other transactions of the type required to be disclosed
pursuant to Items 402 and 404 of Regulation S-K under the Securities Act and the
Exchange Act.

    3.18  INSURANCE.  Schedule 3.18 lists all insurance policies owned or held
by Target and its Subsidiaries. All such insurance policies are in full force
and effect, all premiums with respect thereto covering all periods up to and
including the date hereof have been paid to the extent due and no notice of
cancellation or termination has been received with respect to any such policy.
No insurance policy required to be listed on Schedule 3.18 shall be cancelable,
terminable, or subject to renegotiation as to terms or coverage by the issuer
thereof as a result of the consummation of the Merger or the other transactions
contemplated by this Agreement.

    3.19  BOOKS AND RECORDS.  The books of account of Target and its
Subsidiaries reflect all material items of income and expense and all material
assets, liabilities and accruals, and are prepared and maintained in form and
substance adequate for preparing audited financial statements in accordance with
GAAP and in accordance with SAAP as prescribed or permitted by the Pennsylvania,
Delaware and Virginia Departments of Insurance. The minute books of Target and
its Subsidiaries have been provided to Acquiror and contain complete and
accurate summaries of all meetings of directors and stockholders or actions by
written consent since the time of incorporation of Target and its respective
Subsidiaries through the date of this Agreement, and reflect all transactions
referred to in such minutes accurately in all material respects. Such minutes or
consents have not been rescinded or amended except as reflected in such minute
books.

    3.20  COMPLETE COPIES OF MATERIALS.  Target has delivered true and complete
copies of each document that has been requested by Acquiror, its counsel and its

letter, a true and complete copy of which has been made available to Acquiror,
Target and its Subsidiaries have not incurred, nor will they incur, directly or
indirectly, any liability for brokerage or finders' fees or agents' commissions
or investment bankers' fees or any similar charges in connection with this
Agreement or any transaction contemplated hereby.

    3.22  PROXY STATEMENT.  The information supplied by Target for inclusion in
the proxy statement to be sent to the stockholders of Target in connection with

respects with the requirements of the Exchange Act and shall not, on the date

                                      A-26
<PAGE>
Directors of Target, then, to the extent the Board of Directors of Target
believes in good faith (after written advice from its independent financial
advisor) that such Takeover Proposal would, if consummated, result in a
transaction materially more favorable to Target's stockholders from a financial
point of view than the Merger (any such more favorable Takeover Proposal being
referred to in this Agreement as a "Superior Proposal"), and the Board of
Directors of Target determines in good faith after advice from outside legal
counsel that, in such outside legal counsel's judgment, there is a reasonable
basis for the Board of Directors of Target, in order to comply with its
fiduciary duties under applicable Pennsylvania Law, then Target and its
officers, directors, employees, investment bankers, attorneys, accountants and
other representatives retained by it may furnish in connection therewith
information to the Person making such Superior Proposal and engage in
negotiations with such person, and such actions shall not be considered a breach
of this Section 5.2 or any other provisions of this Agreement; provided that in
each such event Target immediately notifies Acquiror of such determination by
the Target Board of Directors and provides Acquiror with a true and complete
copy of the Superior Proposal received from such third Person, and provides (or
has provided) Acquiror with all documents containing or referring to nonpublic
information of Target supplied to such third Person; provided further, that
Target shall provide such nonpublic information pursuant to a nondisclosure
agreement at least as restrictive on such third person as the Confidentiality
Agreement (as defined in Section 6.4) is on Acquiror; and provided further, that
Target shall not, and shall not permit any of its officers, directors, employees
or other representatives to, agree to or endorse any Takeover Proposal or
withdraw its recommendation of the Merger unless Target (i) has provided
Acquiror at least five (5) days prior notice thereof, (ii) has terminated this
Agreement pursuant to Section 8.1(f), (iii) has paid Acquiror all amounts
payable pursuant to Section 8.3(b), and (iv) if required by the terms of the
Target Option Agreement, has performed its obligations under the Target Option
Agreement. Target will promptly notify Acquiror after receipt of any Takeover
Proposal or any notice that any Person is considering making a Takeover Proposal
or any request for nonpublic information relating to Target or any of its
Subsidiaries or for access to the properties, books or records of Target or any
of its Subsidiaries by any Person that has advised Target that it may be
considering making, or that has made, a Takeover Proposal, and will keep
Acquiror fully informed of the status and details of any such Takeover Proposal
notice, and shall provide Acquiror with a true and complete copy of such
Takeover Proposal notice or any amendment thereto, if in writing, or a complete
written summary thereof, if not in writing.

    5.3  NEW EMPLOYMENT AGREEMENTS OR WAIVERS.  Prior to the Closing, Target
shall use commercially reasonable efforts to either (i) enter into amended
employment agreements reasonably satisfactory in form and substance to Acquiror
(the "New Employment Agreements") with each senior management employee of Target
and its Subsidiaries listed on Schedule 5.3, or (ii) receive an Amendment to
Employment Agreement reasonably satisfactory in form and substance to Acquiror
(the "Waiver Agreements") from each such employee pursuant to which, among other
things, each such employee shall waive the right to assert that the acquisition
of Target by Acquiror constitutes a "Change of Control" (as defined in each such
employee's existing employment agreement). Upon execution and delivery thereof,
each New Employment Agreement, and each Waiver Agreement, shall constitute the
legal, valid, binding and enforceable obligations of the parties thereto.

    5.4  OPTION CANCELLATION AGREEMENTS.  Notwithstanding any other provision of
this Agreement to the contrary, prior to the Effective Time Target shall be
permitted to enter into the agreements referred to in Section 2.7 (the "Option
Cancellation Agreements") with persons holding vested (or to be vested) Options
under any Target Stock Option Plans, pursuant to which each such person shall
agree prior to the Closing to cancel all such Options in exchange for the
payment by Target contemplated by Section 2.7; provided, however, that prior to
entering into any Option Cancellation Agreement, Target shall obtain the prior
written consent of Acquiror as to the form thereof, which consent shall not be
unreasonably withheld; and provided further, that each Option Cancellation
Agreement shall by its terms only become effective as of the Effective Time.

supply copies of all correspondence with the SEC or its staff or any other
government officials with respect to the Proxy Statement or any related filing.

    6.6  CONSENTS; COOPERATION.

    (a) Each of Acquiror and Target shall promptly apply for or otherwise seek,
and use its reasonable best efforts to obtain, all consents and approvals
required to be obtained by it for the consummation of the Merger, including
those required under the HSR Act and those required to be obtained from the
Pennsylvania Department of Insurance, the Delaware Department of Insurance, the
Virginia Department of Insurance and the Ohio Department of Insurance, and shall
use reasonable best efforts to obtain all necessary consents, waivers and
approvals under any of the material Contracts of Target and its Subsidiaries in
connection with the Merger for the assignment thereof or otherwise. The Parties
will consult and cooperate with one another, and consider in good faith the
views of one another, in connection with any analyses, appearances,
presentations, memoranda, briefs, arguments, opinions and proposals made or
submitted by or on behalf of any Party in connection with proceedings
(i) before any Insurance Authority, or (ii) relating to or under the HSR Act.

    (b) Each of Acquiror and Target shall use reasonable best efforts to resolve
such objections, if any, as may be asserted by any Governmental Entity with
respect to the transactions contemplated by this Agreement under (i) any
insurance holding company system act or insurance company licensing act
administered by any Insurance Authority and any rules or regulations or policies
thereunder, or (ii) the HSR Act and any other federal, state or foreign
statutes, rules, regulations, orders or decrees designed to prohibit, restrict
or regulate actions having the purpose or effect of monopolization or restraint
of trade (collectively, "Antitrust Laws"). In connection therewith, if any
administrative or judicial action or proceeding is instituted (or threatened to
be instituted) challenging any transaction contemplated by this Agreement as
prohibited by any law administered by an Insurance Authority or as violating any
Antitrust Law, each of Acquiror and Target shall cooperate and use reasonable
best efforts vigorously to contest and resist any such action or proceeding and
to have vacated, lifted, reversed, or overturned any decree, judgment,
injunction or other order, whether temporary, preliminary or permanent (each an
"Order"), that is in effect and prohibits, prevents or restricts consummation of
the Merger or any such other transactions, unless Acquiror and Target mutually
decide in good faith that litigation is not in their respective best interests.
Notwithstanding the immediately preceding sentence, it is expressly understood
and agreed that Acquiror shall have no obligation to litigate or contest any
administrative or judicial action or proceeding or any Order beyond
November 30, 2000. Each of Acquiror and Target shall use reasonable best efforts
to take such action as may be required to cause the expiration of the waiting
periods under the HSR Act with respect to the Merger as promptly as possible
after the execution of this Agreement. Acquiror and Target shall also take any
and all of the following actions to the extent reasonably necessary to obtain
the approval of any Insurance Authority or other Governmental Entity with
jurisdiction over the enforcement of any applicable laws regarding the
transactions contemplated hereby: entering into negotiations; providing
information required by law or governmental regulation; and substantially
complying with any second request for information pursuant thereto.
Notwithstanding anything to the contrary in this Section 6.6, neither Acquiror
nor Target nor any of its Subsidiaries shall be required to take any action that
would reasonably be expected to substantially impair the overall benefits
expected, as of the date hereof, to be realized from the consummation of the
Merger or the other transactions contemplated hereby.

    (c) Notwithstanding anything to the contrary in Section 6.6(a) or (b),
(i) neither Acquiror nor any of its Subsidiaries shall be required to divest any
of their respective businesses, services, product lines, assets, or to take or
agree to take any other action or agree to any limitation that would reasonably
be expected to have a Material Adverse Effect on Acquiror or on Acquiror
combined with the Surviving Corporation after the Effective Time, and
(ii) neither Target nor its Subsidiaries shall be required to divest any of
their respective businesses, services, product lines or assets, or to take or
agree to take any other action or agree to any limitation that would reasonably
be expected to have a Material Adverse Effect on Target.

    6.7  VOTING AGREEMENT.  Pursuant to the request of Acquiror, Target has
caused each Selected Stockholder named in Schedule 3.26 to execute and deliver
to Acquiror the Voting Agreement substantially in the form of Exhibit C
concurrent with the execution of this Agreement.

    6.8  LEGAL REQUIREMENTS.  Each of Acquiror, Merger Sub and Target shall, and
shall cause their respective Affiliates to, take all reasonable actions
necessary to comply promptly with all legal requirements which may be imposed on
any of them with respect to the consummation of the transactions contemplated by
this Agreement, shall promptly cooperate with and furnish information to any
Party necessary in connection with any such requirements imposed upon such other
Party in connection with the consummation of such transactions, and shall take
all reasonable actions necessary to obtain (and cooperate with the other Parties
in obtaining) any consent, approval, order or authorization of, or any
registration, declaration or filing with, any Governmental Entity or other
Person, required to be obtained or made in connection with the taking of any
action contemplated by this Agreement.

    6.9  TARGET OPTION AGREEMENT.  Concurrently with the execution of this
Agreement, Target shall deliver to Acquiror an executed Target Option Agreement
in the form of Exhibit B. Target shall fully perform its obligations under the
Target Option Agreement.

    6.10  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    (a) The Surviving Corporation shall provide rights to indemnification
pursuant to its Articles of Incorporation and Code of Regulations substantially
similar to those now existing and contained in Target's Articles of
Incorporation or Bylaws for the benefit of any Person who served as a director
or officer of Target at any time prior to the Effective Time (the "Indemnified
Parties").

    (b) Until the later of (i) six years after the Effective Time, or (ii) the
termination of the litigation listed as Item 1 on Schedule 3.7(a) and all
appeals therein, or the final settlement thereof, Acquiror shall cause the
Surviving Corporation to use commercially reasonable efforts to provide
officers' and directors' liability insurance in respect of acts or omissions
occurring on or prior to the Effective Time covering each Person currently
covered by Target's officers' and directors' liability insurance policy on terms
substantially similar to those of such policy in effect on the date hereof,
provided that, in satisfying its obligation hereunder, Acquiror shall not be
obligated to cause the Surviving Corporation to pay premiums in excess of 150%
of the amount per annum Target paid in its last full fiscal year, which amount
has been disclosed to Acquiror, and if the Surviving Corporation is unable to
obtain the insurance required by this Section 6.10, it shall obtain as much
comparable insurance as possible for an annual premium equal to such maximum
amount.

    (c) To the extent any claim, action, suit, proceeding or investigation
(whether arising before or after the Effective Time) against an Indemnified
Party exists that arises out of or pertains to any action or omission in his or
her capacity as director or officer of Target occurring prior to the Effective
Time, or arises out of or pertains to the transactions contemplated by this
Agreement for a period of three years after the Effective Time (whether arising
before or after the Effective Time), in each case for which such Indemnified
Party is entitled to be indemnified under the Surviving Corporation's Articles
of Incorporation and Code of Regulations, such Indemnified Party shall be
entitled to be represented by counsel, which counsel may be counsel of Acquiror
(provided that if use of counsel of Acquiror would be expected under applicable
standards of professional conduct to give rise to a conflict between the
position of the Indemnified Person and of Acquiror, the Indemnified Party shall
be entitled instead to be represented by counsel selected by the Indemnified
Party and reasonably acceptable to Acquiror). Following the Effective Time the
Surviving Corporation and Acquiror shall pay the reasonable fees and expenses of
such counsel with respect to a claim for which such Indemnified Party is
entitled to be indemnified under the Surviving Corporation's Articles of
Incorporation and Code of Regulations promptly after statements therefor are
received and the Surviving Corporation and Acquiror will cooperate in the
defense of any such matter; provided, however, that such Indemnified Party has

                                      A-30
<PAGE>
complied with any requirements stipulated by the Pennsylvania Law or the Ohio
Law, as applicable, provided further, that neither the Surviving Corporation nor
Acquiror shall be liable for any settlement effected without its written consent
(which consent shall not be unreasonably withheld); and provided, further, that,
in the event that any claim or claims for indemnification are asserted or made
within such three year period, all rights to indemnification in respect to any
such claim or claims shall continue until the disposition of any and all such
claims. The Indemnified Parties as a group may retain only one law firm to
represent them with respect to any single action unless there is, under
applicable standards of professional conduct, a conflict on any significant
issue between the position of any two or more Indemnified Parties. Acquiror
hereby consents to the continuation of the existing legal representation of
Target and the other named defendants in the litigation matter referred to as
Item 1 in Schedule 3.7(a).

    6.11  BEST EFFORTS AND FURTHER ASSURANCES.  Each of the Parties shall use
reasonable best efforts to effectuate the transactions contemplated hereby and
to fulfill and cause to be fulfilled the conditions to Closing hereunder. Each
Party, at the reasonable request of another Party, shall execute and deliver
such other instruments and do and perform such other acts and things as may be
necessary or desirable for effecting completely the consummation of the Merger
and the transactions contemplated hereby.

representations, warranties or obligations hereunder and such breach shall not
have been cured within fifteen (15) business days of receipt by Target of
written notice of such breach, or if such breach cannot be cured by Target

that the provisions of Section 6.4, Section 8.3, Article IX, Article X, and this
Section 8.2 shall remain in full force and effect and survive any termination of
this Agreement; provided further, that notwithstanding anything to the contrary
contained in this Agreement, if this Agreement is terminated by a Party because
of the breach of this Agreement by another Party or because one or more of the

                            TARGET OPTION AGREEMENT

    This Target Option Agreement (this "Agreement") is dated as of May 10, 2000
between Ohio Farmers Insurance Company, an Ohio corporation ("Acquiror"), and
Old Guard Group, Inc., a Pennsylvania corporation ("Target"). Acquiror and
Target are hereinafter collectively referred to as the "Parties" and
individually as a "Party."

                                    RECITALS

    A. Concurrently with the execution and delivery of this Agreement, Target,
Acquiror and Westfield Merger Sub, Inc., an Ohio corporation ("Merger Sub"), are
entering into an Agreement and Plan of Reorganization, dated as of the date
hereof as amended from time to time (the "Reorganization Agreement"), providing
that, among other things, upon the terms and subject to the conditions thereof,
Target and Merger Sub shall merge (the "Merger").

    B. As a condition and inducement to Acquiror's willingness to enter into the
Reorganization Agreement, Acquirer has required that Target agree, and Target
has so agreed, to grant to Acquiror an option with respect to certain shares of
Target's common stock on the terms and subject to the conditions set forth
herein.

    C. Capitalized terms used herein (or other terms defined in the
Reorganization Agreement) but not defined in this Agreement shall have the
meanings set forth in the Reorganization Agreement.

    NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein and in the Reorganization Agreement,
the receipt, sufficiency and adequacy of which is hereby acknowledged, the
Parties agree as follows:

    1.  GRANT OF OPTION.  Target hereby grants Acquiror an irrevocable option
(the "Target Option") to purchase up to 367,000 shares (the "Target Shares") of
the common stock, without par value, of Target (the "Target Common Stock") in
the manner set forth herein at a price (the "Exercise Price") equal to $12.00
per Target Share, payable in cash.

    2.  EXERCISE OF OPTION.  The Target Option may be exercised by Acquiror, in
whole or in part, at any time or from time to time, after the occurrence of any
of the events described in Section 8.3(b) of the Reorganization Agreement, or if
a Takeover Proposal or Trigger Event is consummated as set forth in
Section 8.3(c) of the Reorganization Agreement. In the event Acquiror elects to
exercise the Target Option, Acquiror shall deliver to Target a written notice
(an "Exercise Notice") specifying the total number of Target Shares it wishes to
purchase pursuant thereto. Each closing of a purchase of Target Shares (a
"Closing") shall occur at a place, on a date, and at a time designated by
Acquiror in an Exercise Notice delivered at least two business days prior to the
date of the Closing. Except as provided in the last sentence of this Section 2,
the Target Option shall terminate upon the earlier of: (i) the Effective Time;
(ii) the termination of the Reorganization Agreement pursuant to Section 8.1
thereof (other than a termination in connection with which Acquiror is or will
be entitled to any payments as specified in Section 8.3(b) or (c) thereof);
(iii) 181 days following any termination of the Reorganization Agreement in
connection with which Acquiror is or will be entitled to a payment as specified
in Section 8.3(b) thereof (or if, at the expiration of such 181 day period, the
Target Option cannot be exercised by reason of any applicable judgment, decree,
order, law or regulation, ten (10) business days after such impediment to
exercise shall have been removed or shall have become final and not subject to
appeal); or (iv) 12 months and one day following any termination of the
Reorganization Agreement in connection with which Acquiror is or will be
entitled to a payment as specified in Section 8.3(c) thereof (or if, at the
expiration of such 12 months and one day period, the Target Option cannot be
exercised by reason of any applicable judgment, decree, order, law or
regulation, ten (10) business days after such impediment to exercise shall have
been removed or shall

                                      A-44
<PAGE>
have become final and not subject to appeal). Notwithstanding the termination of
the Target Option, Acquiror shall be entitled to exercise the Target Option if
it has given the Exercise Notice in accordance with the terms hereof prior to
the termination of the Target Option, and the termination of the Target Option
shall not affect any rights hereunder which by the terms of this Agreement do
not terminate or expire prior to or as of such termination.

    3.  CONDITIONS TO CLOSING.  The obligation of Target to issue the Target
Shares to Acquiror hereunder is subject to the conditions that (i) all waiting
periods, if any, under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
as amended, and the rules and regulations promulgated thereunder ("HSR Act"),
applicable to the issuance of the Target Shares hereunder shall have expired or
have been terminated; (ii) all consents, approvals, orders or authorizations of,
or declarations or filings with, any Federal, state or local administrative
agency or commission or other Federal, state or local governmental authority or
instrumentality, if any, including any applicable state Department of Insurance,
required in connection with the issuance of the Target Shares hereunder shall
have been obtained or made, as the case may be; and (iii) no preliminary or
permanent injunction or other order by any court of competent jurisdiction or
governmental agency prohibiting or otherwise restraining such issuance shall be
in effect.

    4.  CLOSING.  At any Closing, (a) Target will deliver to Acquiror a single
certificate in definitive form representing the number of Target Shares
designated by Acquiror in its Exercise Notice, such certificate to be registered
in the name of Acquiror and to bear the legend set forth in Section 9, and
(b) Acquiror will deliver to Target the aggregate price for the Target Shares so
designated and being purchased by wire transfer of immediately available funds.
At any Closing at which Acquirer is exercising the Target Option in part,
Acquiror shall present and surrender this Agreement to Target, and Target shall
deliver to Acquiror an executed new agreement with the same terms as this
Agreement evidencing the right to purchase the balance of the shares of Target
Common Stock purchasable hereunder.

    5.  REPRESENTATIONS AND WARRANTIES OF TARGET.  Target represents and
warrants to Acquirer as follows as of the date hereof and as of each date up to
and including each Closing:

<PAGE>
        (f) except as may be required under the Securities Act of 1933 as
    amended (the "Securities Act"), the execution and delivery of this Agreement
    by Target does not, and the performance of this Agreement by Target will
    not, conflict with, or result in any violation of, or default (with or
    without notice or lapse of time, or both) under, or give rise to a right of
    termination, cancellation or acceleration of any obligation or the loss of a
    benefit under, or the creation of a Lien on assets pursuant to (any such
    conflict, violation, default, right of termination, cancellation or
    acceleration, loss or creation, a "Violation"), (A) any provision of the

    is a party or by which any one or more of them is bound, or (C) any
    judgment, order, decree, statute, law, ordinance, rule or regulation

    6.  REPRESENTATIONS AND WARRANTIES OF ACQUIROR.  Acquiror represents and
warrants to Target as follows, as of the date hereof and as of each date up to
and including each Closing:

        (a) Acquiror is a corporation duly organized, validly existing and in
    good standing under the laws of the State of Ohio and has the corporate
    power and authority to enter into this Agreement and to carry out its
    obligations hereunder;

        (b) the execution and delivery of this Agreement by Acquiror and the
    consummation by Acquiror of the transactions contemplated hereby have been
    duly authorized by all necessary corporate action on the part of Acquiror
    and no other corporate proceedings on the part of Acquiror are necessary to
    authorize this Agreement or any of the transactions contemplated hereby;

        (c) this Agreement has been duly executed and delivered by Acquiror and
    constitutes a valid and binding obligation of Acquiror enforceable against
    Acquiror in accordance with its terms, except as enforceability may be
    limited by bankruptcy and other laws affecting the rights and remedies of
    creditors generally and general principles of equity;

        (d) except as described in Section 4.2 of the Reorganization Agreement,
    the execution and delivery of this Agreement by Acquiror does not, and the
    performance of this Agreement by Acquiror will not, result in any Violation
    pursuant to, (A) any provision of the Articles of Incorporation or Bylaws or
    similar organizational documents of Acquiror, (B) any provisions of any
    Contract, permit, concession, franchise, or license to which Acquiror is a
    party or by which it is bound, or (C) any judgment, order, decree, statute,
    law, ordinance, rule or regulation applicable to Acquiror or its properties
    or assets, which Violation, in the case of each of clauses (B) and (C),
    would have a Material Adverse Effect on Acquiror;

        (e) except as described in Section 4.2 of the Reorganization Agreement
    and Section 3(i) of this Agreement, and except as may be required under the
    Securities Act, the execution and delivery of this Agreement by Acquiror
    does not, and the performance of this Agreement by Acquiror will not,
    require any consent, approval, authorization or permit of, or filing with or
    notification to, any governmental or regulatory authority; and

                                      A-46
<PAGE>
        (f) any Target Shares acquired upon exercise of the Target Option will
    not be, and the Target Option is not being, acquired by Acquiror with a view
    to the public distribution thereof within the meaning of the Securities Act.

    7.  REGISTRATION RIGHTS.

        (a) Following the termination of the Reorganization Agreement, Acquiror
    may by written notice (the "Registration Notice") to Target request Target
    to register under the Securities Act all or any part of the shares of Target
    Common Stock acquired pursuant to this Agreement (the "Restricted Shares")
    beneficially owned by Acquiror (the "Registrable Securities"). Target
    (and/or any person designated in writing by Target to Acquiror) shall
    thereupon have the option exercisable by written notice delivered to
    Acquiror within ten (10) business days after the receipt of the Registration
    Notice, irrevocably to agree to purchase all or any part of the Registrable
    Securities for cash at a price (the "Option Price") equal to the product of
    (i) the number of Registrable Securities multiplied by (ii) the average of
    the closing prices of such shares of Target Common Stock on the NASDAQ
    National Market (or such other exchange or inter-dealer quotation system on
    which Target Common Stock is then listed or quoted) for the ten trading days
    immediately preceding the Notice Date. Any such purchase of Registrable
    Securities by Target shall take place at a closing to be held at the
    principal executive offices of Acquiror at any reasonable date and time
    designated by Target and/or such designee in such notice within ten
    (10) business days after delivery of such notice. Any payment for the shares
    to be purchased hereunder shall be made by delivery of the Option Price at
    the time of such closing by wire transfer of immediately available funds.

        (b) If Target does not elect to exercise its option to purchase pursuant
    to Section 7(a) with respect to all Registrable Securities, Target shall use
    commercially reasonable efforts to effect, as promptly as reasonably
    practicable, the registration under the Securities Act of the unpurchased
    Registrable Securities (including without limitation a shelf registration
    statement under Rule 415 promulgated under the Securities Act); provided,
    however, that (i) Acquiror shall not be entitled to more than an aggregate
    of two effective registration statements hereunder, and (ii) Target will not
    be required to file any such registration statement during any period of
    time (not to exceed 45 days after such request in the case of clause (A)
    below or 135 days in the case of clauses (B) and (C) below) when (A) Target
    is in possession of material nonpublic information which it reasonably
    believes (i) would be detrimental to be disclosed at such time, and
    (ii) after consultation with counsel to Target, such information would have
    to be disclosed if a registration statement were filed at that time;
    (B) Target is required under the Securities Act to include audited financial
    statements for any period in such registration statement and such financial
    statements are not yet reasonably available for inclusion in such
    registration statement; or (C) Target determines, in its reasonable
    judgment, that such registration would materially interfere with any
    financing, acquisition or other material transaction involving Target or any
    of its Subsidiaries. Without Acquiror's prior written consent, no securities
    other than the Registrable Securities shall be included in any such
    registration. If consummation of the sale of any Registrable Securities
    pursuant to a registration hereunder does not occur within 120 days after
    the initial filing with the SEC of the registration statement, the
    provisions of this Section 7 shall again be applicable to any proposed
    registration and the filing of such registration statement shall not reduce
    the number of registrations Acquiror may request pursuant to this
    Section 7. Target shall use commercially reasonable efforts to cause any
    Registrable Securities registered pursuant to this Section 7 to be qualified
    for sale under the securities or Blue Sky laws of such jurisdictions as
    Acquiror may reasonably request and shall continue such registration or
    qualification in effect in such jurisdiction; provided, however, that Target
    shall not be required to qualify to do business in, or consent to general
    service of process in, any jurisdiction by reason of this provision.

                                      A-47
<PAGE>
        (c) The registration rights set forth in this Section 7 are subject to
    the condition that Acquiror shall provide Target with such information with
    respect to Acquiror's Registrable Securities, the plans for the distribution
    thereof, and such other information with respect to Acquiror as, in the
    reasonable judgment of counsel for Target, is necessary to enable Target to
    include in such registration statement all material facts required to be
    disclosed with respect to a registration thereunder.

        (d) If the Target Common Stock is then authorized for quotation or
    trading or listing on the New York Stock Exchange, the NASDAQ National
    Market System, or any other securities exchange or automated quotations
    system, then upon the request of Acquiror, Target shall promptly file an
    application, if required, to authorize for quotation, trading or listing the
    shares of Registrable Securities on such exchange or system and will use
    commercially reasonable efforts to obtain approval, if required, of such
    quotation, trading or listing as soon as reasonably practicable.

        (e) If Target shall propose to register under the Securities Act the
    offering, sale and delivery of Target Common Stock for cash for its own
    account or for any other stockholder of Target pursuant to a firm commitment
    underwriting, Target shall, in addition to Target's other obligations under
    this Section 7, grant Acquiror the right to participate in such registration
    so long as Acquiror participates in the underwriting; provided, however,
    that, if the managing underwriter of such offering advises Target in writing
    that in its reasonable opinion the number of shares of Target Common Stock
    requested to be included in such registration exceeds the number which can
    be sold in such offering, Target shall, after fully including therein all
    shares of Target Common Stock to be sold by Target, include the shares of
    Target Common Stock requested to be included therein by Acquiror pro rata
    (based on the number of shares of Target Common Stock intended to be
    included therein) with the shares of Target Common Stock intended to be
    included therein by persons other than Target.

        (f) A registration effected under this Section 7 shall be effected at
    Target's expense, except for underwriting discounts and commissions and the
    fees and the expenses of counsel to Acquiror, and, if such sale of
    Registrable Securities is being conducted by means of an underwritten public
    offering, Target shall provide to the underwriters such documentation
    (including certificates, opinions of counsel and "comfort" letters from
    auditors) as are customary in connection with underwritten public offerings
    as such underwriters may reasonably require. In connection with any such
    registration, the Parties agree (i) to indemnify each other and the
    underwriters in the customary manner, and (ii) if such sale of Registrable
    Securities is being conducted by means of an underwritten public offering,
    to enter into an underwriting agreement in form and substance customary to
    transactions of this type with the underwriters participating in such
    offering.

    8.  ADJUSTMENT UPON CHANGES IN CAPITALIZATION.

        (a) In the event of any change in Target Common Stock by reason of stock
    dividend, split-up, merger (other than the Merger), recapitalization,
    combination, exchange of shares or the like, the type and number of shares
    or securities subject to the Target Option, and the purchase price per share
    provided in Section 1, shall be adjusted appropriately, and proper provision
    shall be made in the agreements governing such transaction so that Acquiror
    shall receive, upon exercise of the Target Option, the number and class of
    shares or other securities or property that Acquiror would have received in
    respect of the Target Common Stock if the Target Option had been exercised
    immediately prior to such event or the record date therefor, as applicable.

        (b) In the event Target enters in an agreement: (i) to consolidate with
    or merge into any Person, other than Acquiror or one of its Subsidiaries,
    and shall not be the continuing or surviving corporation of such
    consolidation or merger; (ii) to permit any Person, other than Acquiror or
    one of its Subsidiaries, to merge into Target whereby Target shall be the
    continuing or surviving corporation and the shares of Target Common Stock
    outstanding immediately prior to such merger

                                      A-48
<PAGE>
    shall be changed into or exchanged for stock or other securities of Target
    or any other person or cash or any other property, or the outstanding shares
    of Target Common Stock immediately prior to such merger shall after such
    merger represent less than 50% of the outstanding shares and share
    equivalents of the merged company; or (iii) to sell or otherwise transfer
    all or substantially all of its assets to any Person, other than Acquirer or
    one of its Subsidiaries, then, and in each such case, the agreement
    governing such transaction shall make proper provisions so that upon the
    consummation of any such transaction and upon the terms and conditions set
    forth herein, Acquiror shall receive for each Target Share with respect to
    which the Target Option has not been exercised an amount of consideration in
    the form of and equal to the per share amount of consideration that would be
    received by the holder of one share of Target Common Stock less the Exercise
    Price (and, in the event of an election or similar arrangement with respect
    to the type of consideration to be received by holders of Target Common
    Stock, subject to the foregoing, proper provision shall be made so that
    Acquiror, as holder of the Target Option, would have the same election or
    similar rights as would the holder of the number of shares of Target Common
    Stock for which the Target Option is then exercisable).

    9.  RESTRICTIVE LEGEND.  Each certificate representing shares of Target
Common Stock issued to Acquiror hereunder shall include a legend in
substantially the following form:

    THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY
IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

    10.  BINDING EFFECT; NO ASSIGNMENT.  This Agreement shall be binding upon
and inure to the benefit of the Parties and their respective successors and
permitted assigns. Except as expressly provided in this Agreement, neither this
Agreement nor the rights or the obligations of either Party are assignable,
except by operation of law, or with the written consent of the other Party.
Nothing contained in this Agreement, express or implied, is intended to confer
upon any Person other than the Parties and their respective permitted assigns
any rights or remedies of any nature whatsoever. Any Restricted Shares sold by
Acquiror in compliance with the provisions of Section 7 shall, upon consummation
of such sale, be free of the restrictions imposed with respect to such shares by
this Agreement, unless and until Acquiror shall repurchase or otherwise become
the beneficial owner of such shares, and any transferee of such shares shall not
be entitled to the rights of Acquiror. Certificates representing shares sold in
a registered public offering pursuant to Section 7 shall not be required to bear
the legend set forth in Section 9.

    11.  SPECIFIC PERFORMANCE.  The Parties recognize and agree that if for any
reason any provisions of this Agreement are not performed in accordance with
their specific terms or are otherwise breached, immediate and irreparable harm
or injury would be caused for which money damages would not be an adequate
remedy. Accordingly, each Party agrees that, in addition to other remedies, the
other Party shall be entitled to an injunction restraining any violation or
threatened violation of the provisions of this Agreement. In the event any
action should be brought in equity to enforce the provisions of this Agreement,
neither Party will allege, and each Party hereby waives the defense, that there
is adequate remedy at law.

    12.  ENTIRE AGREEMENT.  This Agreement and the Reorganization Agreement
constitute the entire agreement among the Parties with respect to the subject
matter hereof and supersede all other prior agreements and understandings, both
written and oral, among the Parties or any of them with respect to the subject
matter hereof.

    13.  FURTHER ASSURANCE.  Each Party shall execute and deliver all such
further documents and instruments and take all such further actions as may be
necessary in order to consummate the transactions contemplated hereby.

                                      A-49
<PAGE>
    14.  VALIDITY.  The invalidity or unenforceability of any provision of this
Agreement shall not affect the validity or enforceability of the other
provisions of this Agreement, which shall remain in full force and effect. If
any court or other competent authority holds any provision of this Agreement to
be null, void or unenforceable, the Parties shall negotiate in good faith the
execution and delivery of an amendment to this Agreement in order, as nearly as
possible, to effectuate, to the extent permitted by law, the intent of the
Parties with respect to such provision. Each Party agrees that, should any court
or other competent authority hold any provision of this Agreement or part hereof
to be null, void or unenforceable, or order any Party to take any action
inconsistent herewith, or not take any action required herein, the other Party
shall not be entitled to specific performance of such provision or part hereof
or to any other remedy, including but not limited to money damages, for breach
hereof or of any other provision of this Agreement or part hereof as the result
of such holding or order.

    15.  NOTICES.  All notices and other communications hereunder shall be in

                                VOTING AGREEMENT

    This Voting Agreement (this "Agreement") is made and entered into as of
May 10, 2000, between the undersigned stockholders (each a "Stockholder" and
collectively the "Stockholders") of Old Guard Group, Inc., a Pennsylvania
corporation ("Target"), and Ohio Farmers Insurance Company, an Ohio corporation
("Acquiror"). The Stockholders and Acquiror are hereinafter collectively
referred to herein as the "Parties" and individually as a "Party."

                                    RECITALS

    A.  Concurrently with the execution and delivery of this Agreement, Target
and Acquirer are entering into an Agreement and Plan of Reorganization dated as
of the date hereof as the same may be amended from time to time (the
"Reorganization Agreement"), providing for the merger of Target with and into a
wholly owned subsidiary of Acquiror (the "Merger") pursuant to the terms and
conditions thereof.

    B.  As a condition and an inducement to Acquiror entering into the
Reorganization Agreement, pursuant to which each Stockholder will receive the
consideration provided for in the Reorganization Agreement in exchange for each
share of common stock, with no par value, of Target (the "Target Common Stock")
owned by such Stockholder, Acquiror has required that the Stockholders agree,
and the Stockholders have so agreed, to enter into this Agreement whereby each
Stockholder will agree to vote such Stockholder's Shares (as defined below) in
favor of the Merger and against any competing merger proposal.

    NOW, THEREFORE, in consideration of the foregoing and of the mutual
covenants and agreements set forth herein and in the Reorganization Agreement,
the receipt, sufficiency and adequacy of which are hereby acknowledged, the
Parties agree as follows:

    1.  REPRESENTATIONS AND WARRANTIES OF THE STOCKHOLDERS.  Each Stockholder
represents and warrants to Acquiror that such Stockholder:

        (a) is the beneficial owner of that number of shares of Target Common
    Stock set forth opposite such Stockholder's name on EXHIBIT A (such
    Stockholder's "Shares");

        (b) except as described in EXHIBIT A, does not beneficially own (as such
    term is defined in the Securities Exchange Act of 1934, as amended (the
    "Exchange Act")) or own of record any shares of Target Common Stock other
    than such Stockholder's Shares, other than shares of Target Common Stock
    which such Stockholder has the right to obtain upon the exercise of stock
    options outstanding on the date hereof as described on EXHIBIT A; and

        (c) has the right, power and authority to execute and deliver this
    Agreement and to perform such Stockholder's obligations under this
    Agreement, and this Agreement has been duly executed and delivered by such
    Stockholder and constitutes a valid and legally binding agreement of such
    Stockholder, enforceable in accordance with its terms; and such execution,
    delivery and performance by such Stockholder of this Agreement will not
    (i) conflict with, require a consent, waiver or approval under, result in a
    breach of or default under, or result in the termination of, any term of any
    contract, agreement, understanding, commitment or other obligation (written
    or oral) to which such Stockholder is a party or by which such Stockholder
    is bound; (ii) violate any order, judgment, writ, injunction, decree or
    statute, or any rule or regulation, applicable to Stockholder or any of the
    properties or assets of such Stockholder; or (iii) result in the creation
    of, or impose any obligation on such Stockholder to create, any lien, charge
    or other encumbrance of any nature whatsoever upon the Shares, other than in
    favor of Acquiror.

                                      A-52
<PAGE>
    The representations and warranties contained herein shall be made as of the
date hereof and as of each date from the date hereof through and including the
date that the Merger is consummated or this Agreement is terminated in
accordance with its terms.

    2.  AGREEMENT TO VOTE SHARES.  At each meeting of the stockholders of
Target, each Stockholder shall be present (in person or by proxy) and vote such
Stockholder's Shares and any New Shares (as defined in Section 4), and shall
cause any holder of record of such Stockholder's Shares or New Shares to be
present and vote, (a) in favor of adoption and approval of the Reorganization
Agreement and the Merger (and each other action and transaction contemplated by
the Reorganization Agreement or by this Agreement) and (b) against any Takeover
Proposal (as defined in the Reorganization Agreement) other than the Merger (or
any other Takeover Proposal of Acquiror) and against any proposed action or
transaction that would prevent or intentionally delay consummation of the Merger
(or other Takeover Proposal of Acquiror) or is otherwise inconsistent therewith
at every meeting of the stockholders of Target at which any such matters are
considered and at every adjournment thereof. Any such vote shall be cast, or
consent shall be given, in accordance with such procedures relating thereto as
shall ensure that it is duly counted for purposes of determining that a quorum
is present and for purposes of recording the results of such vote. Each
Stockholder shall deliver to Acquiror upon request a proxy substantially in the
form attached hereto as EXHIBIT B, which proxy shall be coupled with an interest
and irrevocable to the extent permitted under Pennsylvania law, with the total
number of such Stockholder's Shares and any New Shares correctly indicated
thereon. Each Stockholder hereby revokes any and all previous proxies granted
with respect to such Stockholder's Shares. Each Stockholder shall also use
reasonable best efforts to take, or cause to be taken, all action, and do, or
cause to be done, all things necessary or advisable in order to consummate and
make effective the transactions contemplated by this Agreement.

    3.  NO VOTING TRUSTS.  After the date hereof, each Stockholder agrees that
such Stockholder will not, nor will such Stockholder permit any entity under
such Stockholder's control to, deposit any Shares or New Shares in a voting
trust or subject any Shares or New Shares to any lien or agreement, proxy,
arrangement or understanding with respect to the voting of such Shares other
than with or in favor of Acquiror.

    4.  ADDITIONAL PURCHASES.  Each Stockholder agrees that in the event (a) of
any stock dividend, stock split, recapitalization, reclassification, combination
or exchange of shares of stock of Target on, of or affecting the Shares of such
Stockholder, (b) such Stockholder purchases or otherwise acquires beneficial
ownership of any shares of Target Common Stock after the execution of this
Agreement (including by exercise of options), or (c) such Stockholder acquires
the right to vote or share in the voting of any shares of Target Common Stock
other than the Shares (collectively, "New Shares"), such Stockholder shall
deliver promptly to Acquiror upon request an irrevocable proxy substantially in
the form attached hereto as Exhibit B with respect to such New Shares. Each
Stockholder also agrees that any New Shares acquired or purchased by such
Stockholder shall be subject to the terms of this Agreement and shall constitute
Shares to the same extent as if they were owned by such Stockholder on the date
hereof.

    5.  NO ENCUMBRANCES.

        (a) Except as expressly contemplated by this Agreement, each
    Stockholder's Shares and the certificates representing such Shares are now,
    and at all times during the term hereof will be, held by such Stockholder,
    or by a nominee or custodian for the benefit of such Stockholder, free and
    clear of all liens, claims, security interests, proxies, voting trusts or
    agreements, understandings or arrangements or any other encumbrances
    whatsoever (other than to the extent set forth on EXHIBIT A to this
    Agreement), except for any encumbrances or proxies arising hereunder.

        (b) Notwithstanding the foregoing each Stockholder shall be permitted to
    sell (or pledge to Target in support of a loan) such portion of New Shares
    (but may not sell any New Shares to

                                      A-53
<PAGE>
    Target or its Subsidiaries (as defined in the Reorganization Agreement))
    solely to pay the exercise price of any employee stock options and tax
    liabilities in respect of an exercise of employee stock options; provided
    that any such New Shares shall be sold (or pledged) subject to the
    irrevocable proxy referred to in Section 2.

    6.  NO SOLICITATION.  Each Stockholder agrees that such Stockholder will
not, directly or indirectly (i) take any action to solicit, initiate or
encourage any Takeover Proposal (as defined in the Reorganization Agreement) or
(ii) engage in negotiations with, or disclose any nonpublic information relating
to Target or any of its Subsidiaries, to any person that has advised Target that
it may be considering making, or that has made, a Takeover Proposal. Such
Stockholder will promptly notify Acquiror after receipt of any Takeover Proposal
or any notice that any person is considering making a Takeover Proposal or any
request for nonpublic information relating to Target or any of its Subsidiaries
or for access to the properties, books or records of Target or any of its
Subsidiaries by any person that has advised Target that it may be considering
making, or that has made a Takeover Proposal and will keep Acquiror fully
informed of the status and details of any such Takeover Proposal notice, and
shall provide Acquiror with a true and complete copy of such Takeover Proposal
notice or any amendment thereto, if it is in writing, or a complete written
summary thereof, if it is not in writing.

    7.  APPRAISAL RIGHTS.  Each Stockholder agrees not to exercise any rights
(including, without limitation, under Title 15, Article B, Chapter 19,
Subchapter C, Section 1930 of the Pennsylvania General Corporation Law) to
demand appraisal of any Target Common Stock which may arise with respect to the
Merger.

    8.  RELIANCE BY ACQUIROR.  Each Stockholder understands and acknowledges
that Acquiror is entering into the Reorganization Agreement in reliance upon
each Stockholder's execution and delivery of this Agreement.

    9.  ACTION IN STOCKHOLDER CAPACITY ONLY.  Each Stockholder makes no
agreement or understanding hereunder as an officer or director of Target. Each
Stockholder executes this Agreement solely in such Stockholder's capacity as a
beneficial owner of the Shares, and nothing herein shall limit or effect any
actions taken in such Stockholder's capacity as an officer or director of
Target. The obligations of each Stockholder under this Agreement are the
several, and not joint, obligations of such Stockholder.

    10.  SPECIFIC PERFORMANCE.  Each Party severally acknowledges that such
Party will be impossible to measure in money the damage to the other Parties if
the Party fails to comply with any of the obligations imposed by this Agreement,
that every such obligation is material and that, in the event of any such
failure, the other Parties will not have an adequate remedy at law or damages.
Accordingly, each Party severally agrees that injunctive relief or other
equitable remedy, in addition to remedies at law or damages, is the appropriate
remedy for any such failure and will not oppose the granting of such relief on
the basis that any other Party has an adequate remedy at law. Each Party
severally agrees that such Party will not seek, and agrees to waive any
requirement for, the securing or posting of a bond in connection with any other
Party's seeking or obtaining such equitable relief.

    11.  HEIRS, SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon
and inure to the benefit of the Parties and their respective heirs, successors
and assigns and shall not be assignable without the written consent of all other
Parties, other than any assignment in whole or in part by Acquiror.

    12.  ENTIRE AGREEMENT.  This Agreement supersedes all prior agreements,
written or oral, among the Parties with respect to the subject matter hereof and
contains the entire agreement among the Parties with respect to the subject
matter hereof. This Agreement may not be amended, supplemented or modified, and
no provisions hereof may be modified or waived, except by an instrument in
writing signed by all the Parties. No waiver of any provisions hereof by any
Party shall be deemed a waiver of any other provisions hereof by any such Party,
nor shall any such waiver be deemed a continuing waiver of any provision hereof
by such Party.

                                      A-54
<PAGE>
    13.  REGULATORY APPROVALS OR EXEMPTIONS.  The Parties acknowledge and agree
that certain transactions contemplated by this Agreement may require receipt by
Acquiror of certain regulatory approvals from, or the granting of one or more
exemptions by, certain applicable insurance regulatory authorities with
jurisdiction over Target and its Subsidiaries (as defined in the Reorganization
Agreement). Upon request each Stockholder shall use commercially reasonable
efforts to cooperate with Acquiror in obtaining any such required insurance
regulatory approvals or exemptions relating to the transactions contemplated by
this Agreement.

    14.  MISCELLANEOUS.

    (a)  EXPENSES.  Each Party shall bear and pay all costs and expenses
incurred by such Party or on such Party's behalf in connection with the
negotiation of this Agreement, including fees and expenses of such Party's own
financial consultants, investment bankers, accountants and counsel.

    (b)  AMENDMENT.  This Agreement may not be amended except by an instrument
in writing signed on behalf of each of the Parties, provided, however, that any
amendment signed by Acquiror and any one or more Stockholders (but not by all
Stockholders) shall be effective to amend this Agreement but only with respect
to the mutual obligations of Acquiror and such executing Stockholder or
Stockholders hereunder.

    (c)  GOVERNING LAW.  This Agreement shall be deemed a contract made under,
and for all purposes shall be construed in accordance with, the internal laws of
the State of Ohio without regard to principles of conflicts of law, except for
those provisions relating to the voting and the proxy with respect to the
Shares, which shall be governed by Pennsylvania law.

    (d)  SEVERABILITY.  If any provision of this Agreement or the application of
such provision to any person or circumstances shall be held invalid by a court
of competent jurisdiction, the remainder of the provision held invalid and the
application of such provision to persons or circumstances, other than the Party
as to which it is held invalid, shall not be affected.

    (e)  COUNTERPARTS.  This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original but all of which
together shall constitute one and the same instrument.

    (f)  TERMINATION.  This Agreement shall terminate upon the earlier of
(i) the Effective Date of the Merger (as provided in the Reorganization
Agreement) or (ii) the termination of the Reorganization Agreement pursuant to
Section 8.1 thereof, provided that no such termination shall extinguish any
liability of a Party for breach of such Party's obligations under this
Agreement. In addition, this Agreement may be terminated by Acquiror at any time
and for any reason as to any or all Stockholders by delivery of a written notice
of termination from Acquiror to such Stockholder or Stockholders, in which case
all rights and obligations of Acquiror hereunder with respect to each such
Stockholder and such Stockholder's Shares, and all obligations of each such
Stockholder hereunder, shall immediately terminate; provided, however, that such
termination by Acquiror pursuant to this sentence shall be without prejudice to
the rights of any Party against any other Party or Parties arising out of or
relating to a breach of this Agreement that occurred prior to such termination.

    (g)  HEADINGS.  All Section headings herein are for convenience of reference
only and are not part of this Agreement and no construction or reference shall
be derived therefrom.

    (h)  NOTICES.  All notices, requests, claims, demands, and other

Board of Directors
Old Guard Group, Inc.

Ladies and Gentlemen:

    You have requested our opinion as to the fairness, from a financial point of
view, to the holders of the outstanding shares of common stock, no par value
(collectively, the "Shareholders"), of Old Guard Group, Inc. (the "Company") of
$12 per share in cash (the "Merger Consideration") proposed to be paid to the
Shareholders pursuant to the Agreement and Plan of Reorganization dated as of
May 10, 2000 (the "Merger Agreement") by and among Ohio Farmers Insurance
Company ("OFIC"), Westfield Merger Sub, Inc., a wholly-owned subsidiary of OFIC
("Merger Sub"), and the Company. Pursuant to the terms of and subject to the
conditions set forth in the Merger Agreement, Merger Sub will be merged with the
Company (the "Merger") and each share of common stock of the Company will be
converted into the right to receive the Merger Consideration upon consummation
of the Merger.

    In connection with our review of the proposed Merger and the preparation of
our opinion herein, we have examined: (a) the Merger Agreement and related
documents; (b) certain publicly available financial statements of the Company;
(c) certain internal business, operating and financial information and forecasts
of the Company (the "Forecasts"), prepared by the senior management of the
Company; (d) information regarding publicly available financial terms of certain
comparable transactions in the industry in which the Company operates;
(e) current and historical market prices and trading volumes of the common stock
of the Company; and (f) certain other publicly available information regarding
the Company. We have also held discussions with members of the senior management
of the Company to discuss the foregoing, have considered other matters which we
have deemed relevant to our inquiry and have taken into account such accepted
financial and investment banking procedures and considerations as we have deemed
relevant.

    In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all the information examined
by or otherwise reviewed or discussed with us for purposes of this opinion. We
have not made or obtained an independent valuation or appraisal of the assets,
liabilities or solvency of the Company. We have been advised by the management

    (B) EXCEPTIONS.--

        (1) Except as otherwise provided in paragraph (2), the holders of the
shares of any class or series of shares that, at the record date fixed to
determine the shareholders entitled to notice of and to vote at the meeting at
which a plan specified in any of section 1930, 1931(d), 1932(c) or 1952(d) is to
be voted on, are either:

            (i) listed on a national securities exchange; or

            (ii) held of record by more than 2,000 shareholders;

shall not have the right to obtain payment of the fair value of any such shares
under this subchapter.

        (2) Paragraph (1) shall not apply to and dissenters rights shall be
available without regard to the exception provided in that paragraph in the case
of:

            (i) Shares converted by a plan if the shares are not converted
    solely into shares of the acquiring, surviving, new or other corporation or
    solely into such shares and money in lieu of fractional shares.

            (ii) Shares of any preferred or special class unless the articles,
    the plan or the terms of the transaction entitle all shareholders of the
    class to vote thereon and require for the adoption of the plan or the
    effectuation of the transaction the affirmative vote of a majority of the
    votes cast by all shareholders of the class.

            (iii) Shares entitled to dissenters rights under section 1906(c)
    (relating to dissenters rights upon special treatment).

        (3) The shareholders of a corporation that acquires by purchase, lease,
exchange or other disposition all or substantially all of the shares, property
or assets of another corporation by the issuance of shares, obligations or
otherwise, with or without assuming the liabilities of the other corporation and
with or without the intervention of another corporation or other person, shall
not be entitled to the rights and remedies of dissenting shareholders provided
in this subchapter regardless of the fact, if it be the case, that the
acquisition was accomplished by the issuance of voting shares of the corporation
to be outstanding immediately after the acquisition sufficient to elect a
majority or more of the directors of the corporation.

    (C) GRANT OF OPTIONAL DISSENTERS RIGHTS.--The bylaws or a resolution of the
board of directors may direct that all or a part of the shareholders shall have
dissenters rights in connection with any corporate action or other transaction
that would otherwise not entitle such shareholders to dissenters rights.

    (D) NOTICE OF DISSENTERS RIGHTS.--Unless otherwise provided by statute, if a
proposed corporate action that would give rise to dissenters rights under this
subpart is submitted to a vote at a meeting of shareholders, there shall be
included in or enclosed with the notice of meeting:

        (1) a statement of the proposed action and a statement that the
shareholders have a right to dissent and obtain payment of the fair value of
their shares by complying with the terms of this subchapter; and

        (2) a copy of this subchapter.

    (E) OTHER STATUTES.--The procedures of this subchapter shall also be

equitable relief), 1904 (relating to de facto transaction doctrine abolished)
and 2512 (relating to dissenters rights procedure).

SECTION 1572.  DEFINITIONS.

    The following words and phrases when used in this subchapter shall have the
meanings given to them in this section unless the context clearly indicates
otherwise:

    "CORPORATION."  The issuer of the shares held or owned by the dissenter
before the corporate action or the successor by merger, consolidation, division,
conversion or otherwise of that issuer. A plan of division may designate which
of the resulting corporations is the successor corporation for the purposes of
this subchapter. The successor corporation in a division shall have sole
responsibility for payments to dissenters and other liabilities under this
subchapter except as otherwise provided in the plan of division.

    "DISSENTER."  A shareholder or beneficial owner who is entitled to and does
assert dissenters rights under this subchapter and who has performed every act
required up to the time involved for the assertion of those rights.

    "FAIR VALUE."  The fair value of shares immediately before the effectuation
of the corporate action to which the dissenter objects taking into account all
relevant factors, but excluding any appreciation or depreciation in anticipation
of the corporate action.

    "INTEREST."  Interest from the effective date of the corporate action until
the date of payment at such rate as is fair and equitable under all of the
circumstances, taking into account all relevant factors including the average
rate currently paid by the corporation on its principal bank loans.

SECTION 1573.  RECORD AND BENEFICIAL HOLDERS AND OWNERS.

    (A) RECORD HOLDERS OF SHARES.--A record holder of shares of a business
corporation may assert dissenters rights as to fewer than all of the shares
registered in his name only if he dissents with respect to all the shares
beneficially owned by any one person and discloses the name and address of the
person or persons on whose behalf he dissents. In that event, his rights shall
be determined as if the shares as to which he has dissented and his other shares
were registered in the names of different shareholders.

    (B) BENEFICIAL OWNERS OF SHARES.--A beneficial owner of shares of a business
corporation who is not the record holder may assert dissenters rights with
respect to shares held on his behalf and shall be treated as a dissenting
shareholder under the terms of this subchapter if he submits to the corporation
not later than the time of the assertion of dissenters rights a written consent
of the record holder. A beneficial owner may not dissent with respect to some
but less than all shares of the same class or series owned by the owner, whether
or not the shares so owned by him are registered in his name.

SECTION 1574.  NOTICE OF INTENTION TO DISSENT.

    If the proposed corporate action is submitted to a vote at a meeting of
shareholders of a business corporation, any person who wishes to dissent and
obtain payment of the fair value of his shares must file with the corporation,
prior to the vote, a written notice of intention to demand that he be paid the
fair value of his shares if the proposed action is effectuated, must effect no
change in the beneficial ownership of his shares from the date of such filing
continuously through the effective date of the proposed action and must refrain
from voting his shares in approval of such action. A dissenter who fails in any
respect shall not acquire any right to payment of the fair value of his shares
under this subchapter. Neither a proxy nor a vote against the proposed corporate
action shall constitute the written notice required by this section.

                                      C-3
<PAGE>
SECTION 1575.  NOTICE TO DEMAND PAYMENT.

    (A) GENERAL RULE.--If the proposed corporate action is approved by the
required vote at a meeting of shareholders of a business corporation, the
corporation shall mail a further notice to all dissenters who gave due notice of
intention to demand payment of the fair value of their shares and who refrained
from voting in favor of the proposed action. If the proposed corporate action is
to be taken without a vote of shareholders, the corporation shall send to all
shareholders who are entitled to dissent and demand payment of the fair value of
their shares a notice of the adoption of the plan or other corporate action. In
either case, the notice shall:

        (1) State where and when a demand for payment must be sent and
    certificates for certificated shares must be deposited in order to obtain
    payment.

        (2) Inform holders of uncertificated shares to what extent transfer of
    shares will be restricted from the time that demand for payment is received.

        (3) Supply a form for demanding payment that includes a request for
    certification of the date on which the shareholder, or the person on whose
    beneficial shareholder dissents, acquired beneficial ownership of the
    shares.

        (4) Be accompanied by a copy of this subchapter.

    (B) TIME FOR RECEIPT OF DEMAND FOR PAYMENT.--The time set for receipt of the
demand and deposit of certificated shares shall be not less than 30 days from
the mailing of the notice.

SECTION 1576.  FAILURE TO COMPLY WITH NOTICE TO DEMAND PAYMENT, ETC.

    (A) EFFECT OF FAILURE OF SHAREHOLDER TO ACT.--A shareholder who fails to
timely demand payment, or fails (in the case of certificated shares) to timely
deposit certificates, as required by a notice pursuant to section 1575 (relating
to notice to demand payment) shall not have any right under this subchapter to
receive payment of the fair value of his shares.

    (B) RESTRICTION ON UNCERTIFICATED SHARES.--If the shares are not represented
by certificates, the business corporation may restrict their transfer from the
time of receipt of demand for payment until effectuation of the proposed
corporate action or the release of restrictions under the terms of
section 1577(a) (relating to failure to effectuate corporate action).

    (C) RIGHTS RETAINED BY SHAREHOLDER.--The dissenter shall retain all other
rights of a shareholder until those rights are modified by effectuation of the
proposed corporate action.

SECTION 1577.  RELEASE OF RESTRICTIONS OR PAYMENT FOR SHARES.

    (A) FAILURE TO EFFECTUATE CORPORATE ACTION.--Within 60 days after the date
set for demanding payment and depositing certificates, if the business
corporation has not effectuated the proposed corporate action, it shall return
any certificates that have been deposited and release uncertificated shares from
any transfer restrictions imposed by reason of the demand for payment.

    (B) RENEWAL OF NOTICE TO DEMAND PAYMENT.--When uncertified shares have been
released from transfer restrictions and deposited certificates have been
returned, the corporation may at any later time send a new notice conforming to
the requirements of section 1575 (relating to notice to demand payment), with
like effect.

    (C) PAYMENT OF FAIR VALUE OF SHARES.--Promptly after effectuation of the
proposed corporate action, or upon timely receipt of demand for payment if the
corporate action has already been effectuated, the corporation shall either
remit to dissenters who have made demand and (if their shares are certificated)
have deposited their certificates the amount that the corporation estimates to
be the fair value of the

                                      C-4
<PAGE>
shares, or give written notice that no remittance under this section will be
made. The remittance or notice shall be accompanied by:

        (1) The closing balance sheet and statement of income of the issuer of
    the shares held or owned by the dissenter for a fiscal year ending not more
    than 16 months before the date of remittance or notice together with the
    latest available interim financial statements.

        (2) A statement of the corporation's estimate of the fair value of the
    shares.

        (3) A notice of the right of the dissenter to demand payment or
    supplemental payment, as the case may be, accompanied by a copy of this
    subchapter.

    (D) FAILURE TO MAKE PAYMENT.--If the corporation does not remit the amount
of its estimate of the fair value of the shares as provided by subsection (c),
it shall return any certificates that have been deposited and release
uncertificated shares from any transfer restrictions imposed by reason of the
demand for payment. The corporation may make a notation on any such certificate
or on the records of the corporation relating to any such uncertificated shares
that such demand has been made. If shares with respect to which notation has
been so made shall be transferred, each new certificate issued therefor or the
records relating to any transferred uncertificated shares shall bear a similar
notation, together with the name of the original dissenting holder or owner of
such shares. A transferee of such shares shall not acquire by such transfer any
rights in the corporation other than those which the original dissenter had
after making demand for payment of their fair value.

SECTION 1578.  ESTIMATE BY DISSENTER OF FAIR VALUE OF SHARES.

    (A) GENERAL RULE.--If the business corporation gives notice of its estimate
of the fair value of the shares, without remitting such amount, or remits
payment of its estimate of the fair value of a dissenter's shares as permitted
by section 1577(c) (relating to payment of fair value of shares) and the
dissenter believes that the amount stated or remitted is less than the fair
value of his shares, he may send to the corporation his own estimate of the fair
value of the shares, which shall be deemed a demand for payment of the amount or
the deficiency.

    (B) EFFECT OF FAILURE TO FILE ESTIMATE.--Where the dissenter does not file
his own estimate under subsection (a) within 30 days after the mailing by the
corporation of its remittance or notice, the dissenter shall be entitled to no
more than the amount stated in the notice or remitted to him by the corporation.

SECTION 1579.  VALUATION PROCEEDINGS GENERALLY.

    (A) GENERAL RULE.--Within 60 days after the latest of:

        (1) effectuation of the proposed corporate action;

        (2) timely receipt of any demands for payment under section 1575
    (relating to notice to demand payment); or

        (3) timely receipt of any estimates pursuant to section 1578 (relating
    to estimate by dissenter of fair value of shares);

if any demands for payment remain unsettled, the business corporation may file
in court an application for relief requesting that the fair value of the shares
be determined by the court.

    (B) MANDATORY JOINDER OF DISSENTERS.--All dissenters, wherever residing,
whose demands have not been settled shall be made parties to the proceeding as
in an action against their shares. A copy of the application shall be served on
each such dissenter. If a dissenter is a nonresident, the copy may be served on
him in the manner provided or prescribed by or pursuant to 42 Pa.C.S. Ch. 53
(relating to bases of jurisdiction and interstate and international procedure).

                                      C-5
<PAGE>
    (C) JURISDICTION OF THE COURT.--The jurisdiction of the court shall be
plenary and exclusive. The court may appoint an appraiser to receive evidence
and recommend a decision on the issue of fair value. The appraiser shall have
such power and authority as may be specified in the order of appointment or in
any amendment thereof.

    (D) MEASURE OF RECOVERY.--Each dissenter who is made a party shall be
entitled to recover the amount by which the fair value of his shares is found to
exceed the amount, if any, previously remitted, plus interest.

    EFFECT OF CORPORATION'S FAILURE TO FILE APPLICATION.--If the corporation
fails to file an application as provided in subsection (a), any dissenter who
made a demand and who has not already settled his claim against the corporation
may do so in the name of the corporation at any time within 30 days after the
expiration of the 60-day period. If a dissenter does not file an application
within the 30-day period, each dissenter entitled to file an application shall
be paid the corporation's estimate of the fair value of the shares and no more,
and may bring an action to recover any amount not previously remitted.

SECTION 1580.  COSTS AND EXPENSES OF VALUATION PROCEEDINGS.

    (A) GENERAL RULE.--The costs and expenses of any proceeding under
section 1579 (relating to valuation proceedings generally) including the
reasonable compensation and expenses of the appraiser appointed by the court,
shall be determined by the court and assessed against the business corporation
except that any part of the costs and expenses may be apportioned and assessed
as the court deems appropriate against all or some of the dissenters who are
parties and whose action in demanding supplemental payment under section 1578
(relating to estimate by dissenter of fair value of shares) the court finds to
be dilatory, obdurate, arbitrary, vexatious or in bad faith.

    (B) ASSESSMENT OF COUNSEL FEES AND EXPERT FEES WHERE LACK OF GOOD FAITH
APPEARS.--Fees and expenses of counsel and of experts for the respective parties
may be assessed as the court deems appropriate against the corporation and in
favor of any or all dissenters if the corporation failed to comply substantially
with the requirements of this subchapter and may be assessed against either the
corporation or a dissenter, in favor of any other party, if the court finds that
the party against whom the fees and expenses arc assessed acted in bad faith or
in a dilatory, obdurate, arbitrary or vexatious manner in respect to the rights
provided by this subchapter.

    (C) AWARD OF FEES FOR BENEFITS TO OTHER DISSENTERS.--If the court finds that
the services of counsel for any dissenter were of substantial benefit to other
dissenters similarly situated and should not be assessed against the
corporation, it may award to those counsel reasonable fees to be paid out of the
amounts awarded to the dissenters who were benefitted.
