                                                               October [ ], 1998

To Our Stockholders:

         You are cordially invited to attend a special meeting (the "Special
Meeting") of the stockholders of ALLIED Life Financial Corporation (the
"Company"), to be held on October 30, 1998 at 9:00 a.m., local time, at the
Company's offices, located at 701 Fifth Avenue, Des Moines, Iowa 50391-2003.

         At the Special Meeting, those of you who are holders of the Company's
common stock, without par value (the "Common Shares") and the Company's 6.75%
Series Preferred Stock without par value (the "6.75% Preferred Shares" or the
"Preferred Shares" and together with the Common Shares, the "Shares"), at the
close of business on October 9, 1998 will be entitled to consider and vote upon
a proposal to approve and adopt an Agreement and Plan of Merger, dated as of
June 3, 1998, as amended as of August 31, 1998 (as so amended, the "Merger
Agreement"), by and among the Company, Nationwide Mutual Insurance Company, an
Ohio mutual insurance company ("Nationwide"), and Nationwide Life Acquisition
Corporation, an Ohio corporation and a wholly owned subsidiary of Nationwide
("Acquisition Sub"). Pursuant to the Merger Agreement, Acquisition Sub will be
merged with and into the Company (the "Merger"), with the Company surviving the
Merger as a subsidiary of Nationwide. In the Merger, each Common Share
outstanding on the effective date of the Merger (the "Effective Date") (other
than Common Shares held by stockholders who perfect their appraisal rights under
Iowa law, Common Shares then held by Acquisition Sub or Nationwide and Common
Shares held in the Company's treasury) will be converted into the right to
receive $30.00 per share in cash, without interest. The 6.75% Preferred Shares
will not be converted into the right to receive cash as part of the Merger.
Details of the Merger and other important information are set forth in the
enclosed Information Statement, which you are urged to read carefully.

         As previously communicated in the Solicitation/Recommendation Statement
on Schedule 14D-9, mailed to stockholders in June of this year, your Board of
Directors believes that the Merger is in the best interests of the Company and
its stockholders. In arriving at its decision to recommend the Merger, the Board
of Directors carefully reviewed and considered the terms and conditions of the
Merger Agreement and the factors described in the enclosed Information
Statement.

         The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition of the Company by Nationwide. On June 10, 1998,
Acquisition Sub commenced a tender offer (the "Offer") to purchase all
outstanding Common Shares at a price of $30.00 per Common Share. Pursuant to the
Offer, which expired at 5:00 p.m., New York City time, on September 30, 1998
(the "Expiration Date"), Acquisition Sub acquired approximately ___% of the
outstanding Common Shares. In addition, pursuant to the completion of the merger
of ALLIED Mutual Insurance Company ("ALLIED Mutual") with and into Nationwide on
October 1, 1998, Nationwide owns approximately ___% of the outstanding Common
Shares and 100% of the 6.75% Preferred Shares. As a result of the purchase by
Acquisition Sub of Common Shares in the Offer and the merger of ALLIED Mutual
with and into Nationwide, as of the Record Date Nationwide and Acquisition Sub
will own ___% of the outstanding Common Shares and 100% of the 6.75% Preferred
Shares, representing approximately ___% of the voting power of all outstanding
securities of the Company.

         Nationwide and Acquisition Sub have agreed to vote all Common Shares
acquired in the Offer in favor of the Merger. Approval of the Merger Agreement
requires the affirmative vote of the holders of a majority of the voting power
of the outstanding Common Shares and 6.75% Preferred Shares voting together as a
class. Accordingly, 


                                       2

Nationwide and Acquisition Sub will have sufficient voting power at the Special
Meeting to approve the Merger Agreement without the vote of any other
stockholder of the Company.

         WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US
A PROXY.

                                               Sincerely,

                    NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
                        TO BE HELD ON OCTOBER 30, 1998


         Notice is hereby given that a special meeting (the "Special Meeting")
of stockholders of ALLIED Life Financial Corporation (the "Company") will be
held on October 30, 1998 at 9:00 a.m., local time, at the Company's offices,
located at 701 Fifth Avenue, Des Moines, Iowa 50391-2003, to consider and act
upon the following:

         1. The approval of an Agreement and Plan of Merger, dated as of June 3,
1998 as amended as of August 31, 1998 (as so amended, the "Merger Agreement"),
by and among the Company, Nationwide Mutual Insurance Company, an Ohio mutual
insurance company ("Nationwide"), and Nationwide Life Acquisition Corporation,
an Ohio corporation and  a wholly owned subsidiary of Nationwide ("Acquisition
Sub"), pursuant to which Acquisition Sub will be merged with and into the
Company (the "Merger"), with the Company surviving the Merger as a subsidiary of
Nationwide. In the Merger, each share of the Company's common stock without par
value (the "Common Shares") outstanding on the effective date of the Merger (the
"Effective Date") (other than Common Shares held by stockholders who perfect
their appraisal rights under Iowa law, Common Shares then held by Nationwide and
Common Shares held in the Company's treasury) will be converted into the right
to receive $30.00 per share in cash, without interest. The Company's 6.75%
Series Preferred Stock with no par value (the "6.75% Preferred Shares") will
not, however, be converted into the right to receive cash as part of the Merger.
Details of the Merger and other important information are set forth in the
enclosed Information Statement, which you are urged to read carefully.

         2. The transaction of such other business as may properly come before
the Special Meeting and any adjournment thereof. The Company's Board of
Directors is not aware of, and does not intend to raise, any other matters to be
considered at the Special Meeting.

         Reference is hereby made to the accompanying Information Statement for
more complete information concerning the matters to be acted upon at the Special
Meeting.

         Only holders of record of Common Shares and 6.75% Preferred Shares
(except as indicated below) at the close of business on October 9, 1998 (the
"Record Date") are entitled to vote at the Special Meeting on the approval and
adoption of the Merger Agreement, including the consummation of the transactions
contemplated thereby.

         The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition of the Company by Nationwide. On June 10, 1998,
Acquisition Sub commenced a tender offer (the "Offer") to purchase all
outstanding Common Shares at a price of $30.00 per Common Share. Pursuant to the
Offer, which expired at 5:00 p.m., New York City time, on September 30, 1998
(the "Expiration Date"), Acquisition Sub acquired approximately ___% of the
outstanding Common Shares. In addition, pursuant to the completion of the merger
of ALLIED Mutual Insurance Company ("ALLIED Mutual") with and into Nationwide on
October 1, 1998, Nationwide owns approximately ___% of the outstanding Common
Shares and 100% of the 6.75% Preferred Shares. As a result of the purchase by
Acquisition Sub of Common Shares via the Offer and the merger of ALLIED Mutual
with and into Nationwide, it is anticipated that as of the Record Date
Nationwide and Acquisition Sub will own ___% of the outstanding Common Shares
and 100% of the 6.75% Preferred Shares, representing approximately ___% of the
voting power of all outstanding securities of ALLIED Life.

         Nationwide and Acquisition Sub have agreed to vote all Common Shares
acquired in the Offer in favor of the Merger. Approval of the Merger Agreement
requires the affirmative vote of the holders of a majority of the voting power
of the outstanding Common Shares and 6.75% Preferred Shares voting together as a
class. Accordingly, Nationwide and Acquisition Sub will have sufficient voting
power at the Special Meeting to approve the Merger Agreement without the vote of
any other stockholder of the Company.

         Pursuant to Section 490.1321 of the Iowa Business Corporation Act (the
"IBCA"), if the Merger Agreement is approved by a majority of the voting power
of the holders of Common Shares and Preferred Shares at the Special Meeting and
the Merger is effected by the Company, any stockholder (i) who files with the
Company, before the taking of the vote on the approval of the Merger Agreement,
written objection to the Merger stating that such stockholder intends to demand
payment for such stockholder's shares if the Merger is consummated, and (ii) in
the case of holders of Common Shares, whose shares are not voted in favor of the
Merger Agreement (including any holder of Common Shares who abstains, which
abstention will be treated as a "no" vote for purposes of determining whether
the Merger Agreement has been adopted or approved), may have the right to demand
in writing from the Company, within ___ days after the date of mailing to such
stockholder of notice in writing that the Merger has been authorized at a
shareholders' meeting effective, payment for such stockholder's shares and an
appraisal of the value thereof. The Company and any such stockholder shall in
such cases have the rights and duties and shall follow the procedures set forth
in Sections 490.1301 to 490.1331, inclusive, of the IBCA.

                     FOR THE SPECIAL MEETING OF STOCKHOLDERS
                         TO BE HELD ON OCTOBER 30, 1998


                                  INTRODUCTION

     This Information Statement is being furnished on behalf of the Board of
Directors (the "Board") of ALLIED Life Financial Corporation, an Iowa
corporation (the "Company"), to holders as of the Record Date (as defined below)
of common stock with no par value (the "Common Shares") and 6.75% Series
Preferred Stock, without par value (the "6.75% Preferred Shares" or the
"Preferred Shares"), of the Company, in connection with a special meeting (the
"Special Meeting") of stockholders of the Company to be held on October 30, 1998
at the Company's offices, located at 701 Fifth Avenue, Des Moines, Iowa
50391-2003, at 9:00 a.m., local time. The date on which this Information
Statement is first being mailed or given to stockholders is on or about October

     At the Special Meeting, holders of Common Shares and Preferred Shares
(collectively the "Shares") will be entitled to consider and vote upon a
proposal to approve and adopt an Agreement and Plan of Merger dated as of June
3, 1998 as amended as of August 31, 1998 (as so amended, the "Merger Agreement")
by and among the Company, Nationwide Mutual Insurance Company, an Ohio mutual
insurance company ("Nationwide"), and Nationwide Life Financial Corporation, an
Ohio corporation and a wholly owned subsidiary of Nationwide ("Acquisition
Sub"). Pursuant to the Merger Agreement, Acquisition Sub will be merged with and
into the Company (the "Merger"), with the Company surviving the Merger (the
"Surviving Company" or the "Surviving Corporation") as a subsidiary of
Nationwide. In the Merger, each Common Share outstanding on the effective date
of the Merger (the "Effective Date" or the "Effective Time") (other than Common
Shares held by stockholders who perfect their appraisal rights under Iowa law,
Common Shares then held by Nationwide and Common Shares held in the Company's
treasury) will be converted into the right to receive $30.00 per Common Share in
cash, without interest (the "Offer Price" or the "Merger Consideration"). The
6.75% Preferred Shares will not be converted into the right to receive cash as
part of the Merger.

         WE ARE NOT ASKING YOU FOR A PROXY AND YOU ARE REQUESTED NOT TO SEND US
A PROXY.

         The Merger is the second step in a two-part transaction, the purpose of
which is the acquisition of the Company by Nationwide. On June 10, 1998,
Acquisition Sub commenced a tender offer (the "Offer") to purchase all
outstanding Common Shares at a price of $30.00 per Common Share. Pursuant to the
Offer, which expired at 5:00 p.m., New York City time, on September 30, 1998
(the "Expiration Date"), Acquisition Sub acquired approximately ___% of the
outstanding Common Shares. In addition, pursuant to the completion of the merger
of ALLIED Mutual Insurance Company ("ALLIED Mutual") with and into Nationwide on
October 1, 1998, Nationwide owns approximately ___% of the outstanding Common
Shares and 100% of the 6.75% Preferred Shares. As a result of the purchase by
Acquisition Sub of Common Shares in the Offer and the merger of ALLIED Mutual
with and into Nationwide, it is anticipated that as of the Record Date
Nationwide and Acquisition Sub will own ___% of the outstanding Common Shares
and 100% of the 6.75% Preferred Shares, representing approximately ___% of the
voting power of all outstanding securities of ALLIED Life.

         Nationwide and Acquisition Sub have agreed to vote all Common Shares
and all 6.75% Preferred Shares owned by them in favor of the Merger. Approval of
the Merger Agreement requires the affirmative vote of the holders of a majority
of the voting power of the outstanding Common Shares and 6.75% Preferred Shares
voting together as a class. Accordingly, Nationwide and Acquisition Sub will
have sufficient voting power at the Special Meeting to approve the Merger
Agreement without the vote of any other stockholder of the Company.

                                        culmination of a series of negotiations

                                        began in January 1998 at Nationwide's
                                        initiative. See "THE MERGER--Background

                                        of the Merger are fair to and in the
                                        best interests of the Company and its

                                        decision to enter into the Merger
                                        Agreement was based upon its evaluation
                                        of a number of factors discussed in
                                        detail below, including the opinion of
                                        the Company's financial advisor. See
                                        "THE MERGER--Background and Reasons for

                                        Approval of the Merger Agreement" and

                                        opinion, subject to the matters set
                                        forth in its opinion, the consideration
                                        to be received by the stockholders
                                        pursuant to the Merger is fair to such
                                        stockholders (other than ALLIED Mutual 
                                        and its affiliates) from a financial 
                                        point of view. See "THE MERGER--Opinion

                                        Inc.'s review, is attached to this
                                        Information Statement as Annex III and

Interests of Certain Persons
In the Merger.........................  Nationwide as successor-in-interest to
                                        ALLIED Mutual, and certain of the
                                        directors and officers of the Company
                                        occupy roles or have interests which
                                        could be potentially in conflict with
                                        their roles with respect to the Company,
                                        and/or have interests different from or
                                        potentially in conflict with the
                                        interests of Company stockholders. Such
                                        potential conflicts derive from shared
                                        management, severance arrangements,
                                        participation in the Company's Employee
                                        Stock Ownership Plan, entitlement to
                                        certain Company stock options,

                                        benefits, and protection through
                                        indemnification and insurance. See "THE
                                        MERGER--Interests of Certain Persons in
                                        the Merger" and "THE MERGER

Certain Regulatory Matters............  The Offer and Merger are subject to
                                        certain state regulatory approvals. In

                                        Merger will result therefrom. See "THE

                                        Nationwide as a purchase of the Company
                                        under statutory accounting practices.

                                   THE MERGER

THE COMPANY

         The Company is an Iowa corporation with its principal executive offices
located at 701 Fifth Avenue, Des Moines, Iowa 50391-2003. Through its
subsidiaries, the company underwrites, markets and distributes a select
portfolio of life insurance and annuity products to individuals who live
primarily in rural and suburban areas of the United States. The Company has
approximately 126 employees.

NATIONWIDE AND ACQUISITION SUB

         Acquisition Sub, an Ohio corporation and a wholly owned subsidiary of
Nationwide, was organized in 1998 to acquire the Company and has not conducted
any unrelated activities since its organization. All outstanding shares of
capital stock of Acquisition Sub are owned by Nationwide. The principal
executive offices of Acquisition Sub are located at the principal executive
offices of Nationwide.

         Nationwide is an Ohio mutual insurance company with its principal
executive offices located at One Nationwide Plaza, Columbus, Ohio 43215.
Nationwide is the controlling company of the Nationwide Insurance Enterprise, an
insurance and financial services organization (the "Enterprise"). In 1997,
Nationwide had $5.1 billion of net written premium. Nationwide is a party to the
Nationwide Intercompany Pooling Agreement (the "Nationwide Pooling Agreement")
with 12 other property and casualty insurance companies within the Enterprise
which provides that Nationwide shares in a specified percentage of the combined
underwriting results and dividends to policyowners incurred by such companies
(the "Nationwide Pool"). The insurance companies comprising the Nationwide Pool
were the sixth largest property and casualty insurance group and were the fourth
largest automobile insurance group in the United States, with approximately $8.4
billion in total net written premium at December 31, 1997 and approximately a
3.3% market share. The principal lines of business of the Nationwide Pool based
on net written premium for the year ended December 31, 1997 were personal auto
(approximately 53.9%), commercial operations (approximately 29.4%) and
homeowners (approximately 12.9%).

         Nationwide was originally chartered in the State of Ohio in 1925 as the
Farm Bureau Mutual Automobile Insurance Company and it adopted its present name
in 1955. At December 31, 1997, the Enterprise employed approximately 28,000
employees and Nationwide had more than 4,300 exclusive career agents who market
the Enterprise's core property and casualty products, individual life insurance
and annuity products, as well as other financial services.

BACKGROUND AND REASONS FOR THE MERGER

         The Offer and Merger represent the culmination of a series of
negotiations between Nationwide and the Company that began in January 1998 at
Nationwide's initiative. On January 26, 1998, John E. Evans, Chairman of the
Company, received a telephone call from Dimon R. McFerson, Chairman and Chief
Executive Officer of the Nationwide Insurance Enterprise. In the call, Mr.
McFerson expressed Nationwide's interest in a possible transaction with the
Company, ALLIED Mutual Insurance Company ("ALLIED Mutual") and ALLIED Group,
Inc. ("ALLIED Group," collectively with the Company and ALLIED Mutual,
"ALLIED").

         On January 28, 1998, at the request of Mr. McFerson, Mr. Evans, Douglas
L. Andersen, President and Chief Executive Officer of ALLIED Group, and other
representatives of the Company met with representatives of Nationwide to discuss
Nationwide's interest in acquiring each of the Company, ALLIED Mutual and ALLIED
Group. After the January 28, 1998 meeting, Nationwide provided a draft
confidentiality agreement to Mr. Andersen which did not include customary
standstill provisions.

         On February 6, 1998, Mr. McFerson and Mr. Andersen engaged in further
discussions by telephone regarding Nationwide's interest in acquiring the
Company, ALLIED Mutual and ALLIED Group. Mr. McFerson requested that the
Company, ALLIED Mutual and ALLIED Group agree to deal exclusively with
Nationwide. Mr. Andersen informed Mr. McFerson that the ALLIED companies would
not agree to 


                                       17
<PAGE>   18
deal exclusively with Nationwide, expressed concerns about the absence of an
acceptable confidentiality agreement and other elements of Nationwide's proposal
and stated that Nationwide's proposal could not be considered formally until it
was received in writing by the Company, ALLIED Mutual and ALLIED Group. On
February 10, 1998, ALLIED Group provided to Nationwide its own form of
confidentiality agreement, executed by ALLIED Group, which included a customary
standstill provision.

         Also, on February 10, 1998, Nationwide sent draft merger agreements to
ALLIED Group, which provided for a transaction whereby Nationwide's wholly-owned
subsidiaries would acquire the Company and ALLIED Group and Nationwide would
merge with ALLIED Mutual. The draft merger agreements provided for the purchase
of the shares of ALLIED Group common stock for $47 per share and the purchase of
all outstanding Common Shares for $30 per share, subject to various conditions,
including that the acquisitions of all three ALLIED companies close
simultaneously. The draft merger agreement with ALLIED Mutual provided for no
distribution to ALLIED Mutual's policyholders. Each of the merger agreements
included provisions requiring payment to Nationwide of termination fees,
totaling $75 million in the aggregate, plus expenses of Nationwide in the event
of the termination of the merger agreements under certain circumstances.

         On February 17, 1998, at a joint meeting of the Boards of Directors of
the Company, ALLIED Mutual and ALLIED Group, Nationwide's proposal and proposed
merger agreements were discussed. Following the joint Boards meeting, a special
meeting of the Board of Directors of the Company (the "Board") was convened. At
that meeting it was noted that Nationwide's proposal was contingent on the
consummation of transactions with all three ALLIED companies. The Board noted
that Nationwide's proposal included an exclusivity provision which restricted
the ability of the Company to discuss possible other acquisition proposals. The
Board also noted that Nationwide had refused to sign a confidentiality agreement
with a standstill provision that would prevent it from making a hostile bid for
a specified period of time after it had reviewed confidential documents of the
Company. The Board noted that the substantial termination fees proposed by
Nationwide presented additional risk to the Company. The Board determined that
the proposal was not in the best interests of the Company and determined that
the proposal should be rejected. The Board approved the appointment of Sidley &
Austin to provide legal counsel to the Company in connection with any
negotiations that might occur with Nationwide.

         On February 19, 1998, at a special joint meeting of the Executive
Committees of the Company, ALLIED Mutual and ALLIED Group, Mr. Andersen was
authorized to advise Mr. McFerson that Nationwide's proposal had been rejected.

         On February 19, 1998, Nationwide sent to ALLIED Group a form of
confidentiality agreement, signed on behalf of Nationwide and Nationwide Group
Acquisition Corporation, an Ohio corporation and a wholly owned subsidiary of
Nationwide, which again did not contain the standstill provision and certain
other items that ALLIED Group had proposed.

         On February 20, 1998, Mr. Andersen informed Mr. McFerson via telephone
that the respective Boards of ALLIED had rejected Nationwide's proposal as
presented.

         Later on February 20, 1998, Nationwide sent to ALLIED Group a letter
indicating that Nationwide was withdrawing the executed confidentiality
agreement that it had sent to ALLIED Group on February 19, 1998.

         On May 4, 1998, Mr. McFerson telephoned Mr. Evans to express that
Nationwide wished to re-initiate contact with ALLIED. Mr. Evans indicated that
Nationwide should speak with Mr. Andersen, but requested that Nationwide delay
contacting Mr. Andersen for 30 days.

         On May 18, 1998, Nationwide announced its intention to commence a
tender offer for all the shares of ALLIED Group common stock (the "ALLIED Group
Offer"). On May 19, 1998, Nationwide commenced the ALLIED Group Offer. Also on
May 18 and 19, 1998, Nationwide announced an offer to merge with ALLIED Mutual,
which owns a controlling interest in the Company.


                                       18
<PAGE>   19
         On May 22, 1998, the Company retained Sidley & Austin to act as its
outside legal advisor in connection with the events relating to Nationwide's
possible acquisition of the Company.

         On May 27, 1998, the Coordinating Committee of the Board (the
"Coordinating Committee") was given authority to act as the Special Committee
of the Board (the "Special Committee") in connection with the events relating
to Nationwide's possible acquisition of the Company. The Special Committee met
to consider the need to retain an investment banking firm to provide financial
advisory services relating to Nationwide's tender offer for ALLIED Group and
proposed acquisition of the ALLIED companies. The Special Committee retained the
investment banking firm of Fox-Pitt, Kelton.

         Also on May 27, 1998, the Special Committee again met to continue
discussions about Nationwide and to discuss employment and severance issues.

         On May 28, 1998, Nationwide entered into a separate confidentiality
 agreement with each of the Company, ALLIED Mutual and ALLIED Group.

         From May 28 through May 31, 1998, Credit Suisse First Boston
Corporation, the investment banking firm retained by Nationwide, Fox-Pitt,
Kelton and the financial advisors to each of ALLIED Mutual and ALLIED Group
discussed the various potential transactions involving Nationwide and the ALLIED
companies.

         On May 30, 1998, the Special Committee reconvened to discuss valuation
and strategies relating to a potential transaction. At this meeting,
representatives of Fox-Pitt, Kelton addressed the climate for mergers and
acquisitions in the insurance industry, including takeover premiums. Following
such discussion, the Special Committee directed Fox-Pitt, Kelton to continue
discussions with Credit Suisse First Boston Corporation and the financial
advisors of ALLIED Group and ALLIED Mutual in order to explore a global
transaction with Nationwide, and, if appropriate, to discuss certain aspects of
the results of its valuation of the Company with the financial advisors of
ALLIED Group and ALLIED Mutual.

         On May 30, 1998, at a joint meeting of the Compensation Committees of
each ALLIED company, the Compensation Committee of the Company resolved to amend
certain of the Company's employee benefit plans and severance plans and to adopt
certain new employee benefit plans and severance plans. On June 2, 1998, the
Board ratified such resolutions.

         During the evening of May 31, 1998, a representative of Sidley & Austin
telephoned a representative of Nationwide and discussed certain legal issues
relating to the Joint Marketing Agreement and other matters.

         On the morning of June 2, 1998, Nationwide delivered an initial draft
of a merger agreement which, among other things, provided for a $30 per Share
purchase price, an unspecified minimum tender offer condition and a termination
fee payable by the Company under specified conditions of $5 million. After
reviewing this initial draft, a representative of Sidley & Austin reviewed
various aspects of such initial draft with a member of the Special Committee.

         Negotiations between representatives of the Company and representatives
of Nationwide commenced in the afternoon of June 2. On the evening of June 2,
the Board met again to consider the potential transaction with Nationwide. After
being briefed by Sidley & Austin, the Board discussed terms and conditions under
which it would consider entering into an agreement in principle with Nationwide.
Upon conclusion of such discussion and upon the recommendation of the Special
Committee, the Board authorized the proper officers of the Company to execute
and deliver on behalf of the Company an agreement in principle with Nationwide
if an offer were received from Nationwide which included the terms and
conditions discussed.

         Later in the evening on June 2, 1998, the Special Committee directed
that a press release be issued prior to the commencement of trading on June 3,
1998 stating that the Board was prepared to recommend a 


                                       19
<PAGE>   20
transaction with Nationwide on the terms and conditions discussed at the Board
meetings on June 2, 1998.

         On June 3, 1998, representatives of Sidley & Austin continued
negotiations with representatives of Nationwide with respect to various
provisions of the proposed merger agreement. Although the transaction documents
remained incomplete in certain immaterial respects, the Board and the Special
Committee each met again to hear further reports from management and its
financial and legal advisors as to the status of the proposed transaction. After
briefing the Board as to the terms, conditions and legal effect of the proposed
merger agreement and the directors' fiduciary duties relating thereto, counsel
noted, among other things, that the proposed merger agreement provided (i) for a
cash tender offer by Nationwide for all of the Shares at a purchase price of $30
per Share, (ii) for a reduction of the termination fee to $3 million from the
originally proposed $5 million; (iii) that the tender offer will be followed by
a second-stage merger and (iv) that the proposed merger agreement and all
transactions contemplated thereby will be subject to regulatory approval of the
Iowa Insurance Commission. Counsel also described the progress of the
negotiations and the few remaining issues to be determined, indicating that it
believed the few remaining issues in the merger agreement could be
satisfactorily resolved upon further negotiation. The Special Committee and the
Board then heard a presentation from representatives of Fox-Pitt, Kelton who
reviewed the negotiation process to date and summarized the key financial terms
of the Offer. Fox-Pitt, Kelton delivered its oral fairness opinion (subsequently
confirmed in writing) to the Special Committee. Upon conclusion of this
presentation, the Special Committee recommended and the Board approved the
merger agreement in the form presented to the Board subject to such final
revisions as management might approve in connection with further negotiations.
The Board approved the Offer and the Merger and determined that the Merger is
advisable and that the terms of the Offer and the Merger are fair to and in the
best interests of the Company and its stockholders. The Board also adopted a
resolution recommending that the Company's stockholders accept the Offer and (if
required) approve the Merger Agreement and the Merger. Representatives of
management and Sidley & Austin continued to discuss the provisions of the
proposed merger agreement with Nationwide and its counsel. On the evening of
June 3, 1998 after having satisfactorily resolved all issues, the Company,
Nationwide and the Acquisition Sub executed the Merger Agreement.

         Also on June 3, 1998, Nationwide, Nationwide Group Acquisition
Corporation (a wholly-owned subsidiary of Nationwide) and ALLIED Group Financial
Corporation entered into an Agreement and Plan of Merger, providing for the
merger of Nationwide Group Acquisition Corporation with and into ALLIED Group,
with ALLIED Group being the surviving corporation (the "ALLIED Group Merger").
In the ALLIED Group Merger, the holders of the outstanding shares of common
stock of ALLIED Group (other than Nationwide, as successor-in-interest to ALLIED
Mutual and holders exercising dissenters' rights of appraisal) will receive
$48.25 per share in cash without interest.

REASONS FOR THE BOARD'S APPROVAL OF THE MERGER AGREEMENT

         The Board, at a meeting held on June 3, 1998, acting on the unanimous
recommendation of a committee of the Board (the "Unaffiliated Committee")
consisting of the two (2) directors who are not employed by the Company or
affiliated with ALLIED Mutual or ALLIED Group, and who serve as members of the
Coordinating Committee of the Board, adopted resolution (i) adopting the Merger
Agreement and approving the Offer and the Merger, (ii) determining the terms of
the Offer and the Merger are fair to, and in the best interest of, the Company
and its stockholders, (iii) recommending that the Company's stockholders accept
the Offer, tender their shares pursuant to the Offer and (if required) approve
the Merger Agreement and the Merger and (iv) approving the acquisition of Common
Shares by Acquisition Sub pursuant to the Offer and the other transactions
contemplated by the Merger Agreement.

         In reaching its conclusions described above, the Board considered a
number of factors, including, without limitation, the following:

    (1) The current and historical financial condition and results of operations
of the Company.

    (2) The projected financial condition, results of operations, prospects and
strategic objectives of the Company, as well as the risks involved in achieving
those prospects and objectives.

    (3) The relationship of the price per Common Share pursuant to the Offer
Price to the historical market prices of the Shares.

    (4) The fact that the $30 per Common Share to be received by the Company's
public stockholders in both the Offer and the Merger represents a premium of
25.7% over the closing market price of $23.875 per Common Share on May 15, 1998
(the last trading day prior to the commencement by Nationwide of its tender
offer for the ALLIED Group common stock) and a premium of 15.4% over the closing
market price of $26.00 per Common Share on June 2, 1998 (the last trading day
prior to the Company's announcement that the Board was willing to recommend,
subject to certain limitations, the acquisition of the outstanding Common Shares
by Nationwide for $30 per Common Share).


                                       20
<PAGE>   21
    (5) The presentation of Fox-Pitt, Kelton Inc. to the Special Committee and
the Board at their meetings on June 3, 1998 as to various financial matters
deemed relevant to their consideration and the opinion dated June 3, 1998, of
Fox-Pitt, Kelton to the Special Committee that as of such date and based upon
and subject to various considerations and assumptions set forth therein, the
consideration to be received by the holders of Common Shares in connection with
the Offer and the Merger was fair, from a financial point of view, to the
holders of Common Shares (other than ALLIED Mutual). A copy of the opinion
rendered by Fox-Pitt, Kelton to the Special Committee, setting forth the
procedures followed, the matters considered, the scope of the review undertaken
and the assumptions made by Fox-Pitt, Kelton in arriving at its opinion, is
attached hereto as Annex III and incorporated herein by reference. THE COMPANY'S
STOCKHOLDERS ARE URGED TO READ THIS OPINION IN ITS ENTIRETY.

    (6) The likelihood that the Merger will be consummated in view of the
Shareholder Agreement and the experience, reputation and financial condition of
Nationwide.

    (7) The fact that Duff & Phelps Credit Rating Co. had placed the Company's
claims paying ability rating on "Rating Watch -- Uncertain" in response to
Nationwide's unsolicited proposal to acquire ALLIED Group and ALLIED Mutual due
to the failure to include the Company in such proposal resulting in general
uncertainty as to the future role of the Company in either the ALLIED Group's or
Nationwide's organization.

    (8) The operating relationships between the Company and each of ALLIED
Mutual and ALLIED Group, in particular the Joint Marketing Agreement,
Intercompany Operating Agreement, Management Information Services Agreement and
the potential for adversarial relationships between the parties thereto in the
event that Nationwide acquired control of ALLIED Mutual or ALLIED Group without
entering into a formal acquisition agreement with the Company.

    (9) The effect of the Merger on policyholders of ALLIED Life Insurance
Company and other constituencies.

    (10) The fact that ALLIED Mutual endorsed the acquisition of the Company by
Nationwide at a price of $30 per Common Share.

    (11) The ability of Nationwide to consummate a business combination with the
Company without regard to the Merger Agreement in the event of the consummation
of the transactions contemplated by the ALLIED Mutual Merger Agreement.

    (12) The recommendation of the Special Committee with respect to the
proposed transaction.

    (13) The recommendation of the Company's management with respect to the 
proposed transaction.

    (14) The fact that no other potential strategic partner had expressed an
interest in engaging in a business combination or other strategic transaction
that would likely be on terms as favorable to the Company's stockholders as
those of the Offer and the Merger.

    (15) The terms and conditions of the Merger Agreement and the course of the
negotiations resulting in the execution thereof; including the ability of the
Company to terminate the Merger Agreement under certain conditions if prior to
the purchase of Common Shares pursuant to the Offer, there is a proposal for the
acquisition of the Company which the Board determines represents a more
favorable transaction to the Company and its stockholders than the transactions
contemplated by the Merger Agreement, so long as the Company gives Nationwide
three business days notice of the terms of such proposal and pays Nationwide a
fee of $3,000,000 plus an amount sufficient to reimburse Nationwide for certain
of its expenses incurred in connection with the Merger Agreement.

OPINION OF FOX-PITT, KELTON

         In its role as financial advisor to the Company, Fox-Pitt, Kelton, Inc.
("Fox-Pitt, Kelton") was retained by the Coordinating Committee of the Board of
Directors of the Company (the "Committee") to render its opinion to the
Committee as to the fairness, from a financial point of view, of the
consideration to be received by the holders of the Company's Common Shares
(other than Nationwide and its affiliates) in the Offer and the Merger, taken
together, pursuant to the Merger Agreement. At the meeting of the Company Board 
held on June 3, 1998, Fox-Pitt, Kelton delivered its opinion orally to the
effect that, based upon and subject to various considerations and assumptions
set forth in such opinion, as of such date, the consideration to be received by
the holders of the Company's Common Shares in the Offer and the Merger, taken
together, was fair from a financial point of view to such holders (other than
ALLIED Mutual and its affiliates). Such opinion was later confirmed in writing 
as of such date.

         THE FULL TEXT OF THE WRITTEN OPINION OF FOX-PITT, KELTON, DATED JUNE 3,
1998, WHICH SETS FORTH THE PROCEDURES FOLLOWED, THE MATTERS CONSIDERED, THE
SCOPE OF THE REVIEW AND THE ASSUMPTIONS IN CONNECTION WITH SUCH OPINION, IS
ATTACHED HERETO AS ANNEX III TO THIS INFORMATION STATEMENT AND IS INCORPORATED
HEREIN BY REFERENCE. STOCKHOLDERS OF THE COMPANY ARE URGED TO, AND SHOULD, READ
SUCH OPINION IN ITS ENTIRETY.

         In arriving at its opinion, Fox-Pitt, Kelton (a) reviewed and analyzed
certain publicly available financial statements for the Company and Nationwide
and financial information made available by the management of the Company; (b)
analyzed certain internal financial statements, including financial projections,
and other financial and operating data prepared by the management of the
Company; (c) discussed the past, present and future operations, financial
condition and prospects of the Company with the senior management of the
Company; (d) compared the financial performance and condition of the Company
with that of certain other comparable publicly traded companies; (e) reviewed
and discussed with the senior management of the Company the strategic objectives
of the Merger and certain other benefits of the Merger; (f) reviewed the
financial terms, to the extent publicly available, of certain merger and
acquisition transactions comparable, in whole or in part, to the Merger; (g)
reviewed the Merger Agreement dated June 3, 1998; and (h) performed such other
analyses as they deemed appropriate.

         Fox-Pitt, Kelton assumed and relied upon, without independent

INTERESTS OF CERTAIN PERSONS IN THE MERGER OR IN OPPOSITION TO MATTERS TO BE
ACTED UPON

         No director of the Company has informed the Company of an intention to
oppose the Merger or any other action to be taken at the Special Meeting.

         Stockholders should be aware that the executive officers and directors
of the Company have interests in the Merger that are in addition to or different
from the interests of stockholders of the Company generally. These interests are
discussed below.

         General. In considering the recommendation of the Company Board with
respect to the Merger, Company stockholders should be aware that certain of the
directors and officers of the Company (i) occupy roles or have interests with
respect to other ALLIED Companies, including ALLIED Group, which could be
potentially in conflict with their roles with respect to the Company, and/or
(ii) have interests different from or potentially in conflict with the interests
of Company stockholders.

         The Company Board. John E. Evans, Harold S. Evans and James W. Callison
are also directors of ALLIED Group. Robert J. Woodward, Richard D. Crabtree,
Joseph J. Gasper, Dimon R. McFerson, Robert A. Oakley, members of the Board, are
also directors of Nationwide. These individuals together with Samuel J. Wells,
who is currently President of the Company, are serving as the designees of
Acquisition Sub (the "Acquisition Sub Designees"). As a result of these
overlapping directorships, among other things, there may be a number of
potential conflicts of interest among the Company, ALLIED Mutual and ALLIED
Group. Additionally, Company stockholders should be aware that Nationwide, as
successor to the interests of ALLIED Mutual by virtue of the merger of ALLIED
Mutual with and into Nationwide with Nationwide continuing as the surviving
corporation, and certain of the directors of the Company serving as designees of
Acquisition Sub pursuant to rights granted under the Merger Agreement (i) occupy
roles or have interests with respect to other ALLIED companies and or with
Nationwide and its subsidiaries which could be potentially in conflict with
their roles with respect to the Company, and/or (ii) have interests different
from or potentially in conflict with the interests of Company stockholders.

         Shared Management and Employees. Pursuant to the Intercompany Operating
Agreement among the Company, Nationwide, as successor in interest to ALLIED
Mutual, ALLIED Group and each of their respective subsidiaries (the "IOA"), 
ALLIED Group leases to Nationwide, as successor in interest to ALLIED Mutual and
the former ALLIED Mutual subsidiaries the employees utilized in their operations
for a fee and reimbursement of personnel costs based on certain allocation
methods. In addition, certain executive officers of the Company hold
corresponding positions with Nationwide, as successor in interest to ALLIED
Mutual. Accordingly, such officers may have interests in the Merger arising from
their relationship with Nationwide. Additional information concerning the
benefits that various members of the Company's management are expected to
receive pursuant to the Merger Agreement is presented in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9, initially filed with
the Securities and Exchange Commission ("SEC") on June 10, 1998 (the "Schedule
14D-9"), as amended, the Company's Information Statement on Schedule 14F-1,
filed with the SEC on June 10, 1998, and the exhibits to each such filing.

         Intercompany Operating Agreement. The Company and its subsidiaries are
parties to the IOA with ALLIED Group, Nationwide, as successor in interest to
ALLIED Mutual, and each of their  respective subsidiaries. The following summary
of the IOA is qualified in its  entirety by reference to the full text of the
IOA and the amendments thereto,  copies of which are filed as Exhibits 10.16,
10.3 and 10.15 to the Company's Registration Statement on Form S-1, Registration
No. 33-68928 (the "Form S-1"), Exhibit 10.19 to the Company's Quarterly Report
on Form 10-Q for the Quarter Ended June 30, 1994, and Exhibit 10.24 to the
Company's Annual Report on Form 10-K for the Year Ended December 31, 1994. The
IOA provides for the sharing of employees, office space, agency forces, data
processing, and other services and facilities. The IOA extends through December
31, 2004 and continues thereafter subject to any party providing two years
notice that such party intends to cease participation.

         ALLIED Group leases to Nationwide, as successor in interest to ALLIED
Mutual, and the former ALLIED Mutual subsidiaries (except for the Company) the
employees utilized in their operations for a fee and reimbursement of personnel
costs based on certain allocation methods. ALLIED Group is obligated to provide
the entire requirements for employees to Nationwide, as successor in interest to
ALLIED Mutual, and the former ALLIED Mutual subsidiaries (other than the
Company), but Nationwide, as successor in interest to ALLIED Mutual, reserves
the right to hire employees independently rather than leasing them from ALLIED
Group. ALLIED Group has the right to determine the compensation and benefits of
all leased employees. However, if ALLIED Group wishes to adopt or amend any
employee benefit plan or program and pass on the increased costs thereof with
respect to employees leased by Nationwide, as successor in interest to ALLIED
Mutual, it must obtain the approval of Nationwide, as successor in interest to
ALLIED Mutual (or a joint Compensation Committee consisting of directors of the
Company and Nationwide). The IOA contains a covenant not to compete that binds
each of the Company, ALLIED Group, and Nationwide, as successor in interest to
ALLIED Mutual, not to engage in a business that competes with the products or
markets of any other party or such party's subsidiaries for the term of the IOA
and five years thereafter.

         Any disputes regarding the use of occupancy or facilities or the terms
on which property is leased or used are to be referred to the Coordinating
Committee, consisting of two directors of each of the Company, Nationwide, as
successor in interest to ALLIED Mutual, and ALLIED Group, for resolution.
Decisions of the Coordinating Committee must be unanimous and are binding on the
parties. If an issue is not resolved by the Coordinating Committee, it will be
submitted to arbitration. In such arbitration, each party to the dispute selects
one arbitrator, and if such dispute involves only two parties, such arbitrators
select third arbitrator.

         During 1997, ALLIED Group received revenues of $2.6 million for
employees leased to ALLIED Mutual and certain of ALLIED Mutual's subsidiaries,
substantially all of which represented cost reimbursement. The IOA also provides
for the leasing by Nationwide, as successor in interest to ALLIED Mutual, to
ALLIED Group of substantially all of the office space utilized by ALLIED Group
and the provision of data processing services by the ALLIED Group to Nationwide,
as successor in interest to ALLIED Mutual, and its subsidiaries. ALLIED Group
paid to ALLIED Mutual rent expense for office space of $3.6 million for the year
ended December 31, 1997. Nationwide, as successor in interest to ALLIED Mutual,
the Company, and ALLIED Group share agency forces as well as other services and
facilities.

Management Information Services Agreement

         The Company, Nationwide, as successor in interest to ALLIED Mutual,
ALLIED Group, and other affiliated companies are parties to a Management
Information Services Agreement ("MIS Agreement") with AMCO, whereby AMCO
provides certain computer services, printing, equipment leasing, and mail and
communication services to affiliates on a fee basis. The following summary of
the MIS Agreement is qualified in its entirety by reference to the full text of
the MIS Agreement and the amendments thereto, copies of which are filed as
Exhibits 17 and 18 to the Schedule 14D-9. The agreement terminates on December
31, 2004 and has an extension provision similar to that in the IOA described
above. Any disputes under this agreement are to be referred to the Coordinating
Committee for resolution. Decisions of the Coordinating Committee must be
unanimous and are binding on the parties. If an issue is not resolved by the
Coordinating Committee, it will be submitted to arbitrators for resolution. For
the year 1997, amounts paid to AMCO and certain subsidiaries of the ALLIED Group
by ALLIED Mutual, the Company and their subsidiaries under the MIS Agreement
were $2.5 million.

         In the event of a change of control of the Company, either ALLIED Group
or Nationwide, as successor in interest to ALLIED Mutual, may, in its sole
discretion at any time after such change of control, (i) terminate the MIS
Agreement and IOA upon six months' notice to the Company, (ii) extend the term
of the MIS Agreement and IOA for up to 10 additional years beyond December 31,
2004 upon six months' notice to the Company, or (iii) allow the agreements to
continue in effect. A change of control is any event whereby a person, group or
entity unaffiliated with the Company or Nationwide, as successor in interest to
ALLIED Mutual, acquires the ownership of 50% or more of the voting stock of the
Company. In the event of a change of control of ALLIED Group, Nationwide, as
successor in interest to ALLIED Mutual, may, in its sole discretion at any time
after such change of control, (i) terminate the  MIS Agreement and IOA upon six
months' notice, (ii) extend the term of both agreements for up to 10 additional
years beyond December 31, 2004 upon six months' notice to the Company, AMCO,
ALLIED Property and Casualty and Depositors, or (iii) allow the agreements to
continue in effect. The Company enjoys the same rights with respect to the MIS
Agreement and the IOA in the event of a change of control of ALLIED Group. A
change of control is any event whereby a person, group or entity unaffiliated
with ALLIED Group or Nationwide, as successor in interest to ALLIED Mutual,
acquires the ownership of 50% or more of the voting stock of the Company.

Joint Marketing Agreement

         AMCO, ALLIED Property and Casualty, and Depositors are parties to the
ALLIED Group Joint Marketing Agreement ("JMA") with Nationwide, as successor in
interest to ALLIED Mutual, and ALLIED Life Insurance Company ("ALIC"). The
following summary of the JMA is qualified in its entirety by reference to the
full text of the JMA and the amendments thereto, copies of which are filed as
Exhibits 19 and 20 to the Schedule 14D-9. The JMA requires Nationwide, as
successor in interest to ALLIED Mutual, and the Company's property-casualty
subsidiaries to promote to their customers and agents the sale of the products
of ALIC. The JMA provides for payment by ALIC to AMCO (as pool administrator for
the property-casualty companies) of an annual access fee of $100,000 plus an
annual new production incentive fee ("NPIF"), calculated based on the percentage
increase from the preceding year's production credit premiums for ALIC produced
by the independent property-casualty agencies representing Nationwide, as
successor in interest to ALLIED Mutual, AMCO, ALLIED Property and Casualty, and
Depositors ("ALLIED agencies"). The annual NPIF is not payable unless production
credit premiums increase by at least 10% over the prior year and is capped at an
increase of 25% over the prior year. For the year ended December 31, 1997, the
fee incurred by ALIC under the JMA totaled $100,000. The JMA also provides for
joint systems development, including joint data bases of customers and agents,
multiple account billing systems, marketing plans and promotions, and other
systems to be developed. Development costs are to be allocated on a mutually
agreeable basis reflecting projected and actual utilization of the systems.

         The JMA continues to the year 2008 and continues thereafter subject to
termination on two years notice given by any party. The JMA contains a
non-compete provision structured along product lines which are applicable during
the term of the JMA and for a period of ten years thereafter. The non-compete
provision prevents Nationwide, as successor in interest to ALLIED Mutual, and
the property-casualty subsidiaries of ALLIED Group, directly or indirectly
through any subsidiary, affiliate, joint venture or partnership from selling
life insurance or annuities in the states where ALIC now sells these life
products (or on termination of the JMA, any states where the life insurance and
annuity products are sold by ALIC). Nationwide, as successor in interest to
ALLIED Mutual, and the property-casualty subsidiaries, which are not licensed to
sell life insurance or annuity products, do not operate in all the states in
which ALIC operates. The JMA non-compete provision also prevents ALIC from
offering property-casualty products in states in which Nationwide, as successor
in interest to ALLIED Mutual, and the property-casualty subsidiaries of the
ALLIED Group now operate. In the event of a change of control of ALIC or the
Company (whenever ownership of 50% or more of the voting stock is acquired by a
nonaffiliated party), ALLIED Group, Nationwide, as successor in interest to
ALLIED Mutual, or any of ALLIED Group's property-casualty subsidiaries may (i)
terminate it upon six months' notice; (ii) extend the term for up to ten
additional years beyond 2008; or (iii) allow the JMA to continue in effect
without change. Those three rights are also given to ALIC in the event of a
change of control of ALLIED Group, any of its property-casualty subsidiaries or
Nationwide, as successor in interest to ALLIED Mutual. Pursuant to the ALLIED
Life Merger Agreement, however, the Company has agreed that prior to the
termination of the ALLIED Life Merger Agreement, the Company will not invoke
against ALLIED Group or any of its affiliates any of the covenants not to
compete or agreements not to compete contained in the IOA and JMA. Disputes are
to be resolved by the Coordinating Committee. Decisions of the Coordinating
Committee must be unanimous and are binding on the parties. If the Coordinating
Committee fails to resolve an issue, it would be submitted to arbitration. In
such arbitration, one arbitrator will be appointed jointly by Nationwide, as
successor in interest to ALLIED Mutual, and the ALLIED Group's property-casualty
subsidiaries and a second arbitrator will be appointed by the Company. Both
arbitrators so selected will jointly select a third arbitrator.

Other Arrangements and Transactions

         The Company and Nationwide, as successor in interest to ALLIED Mutual,
are parties to a Stock Rights Agreement which expires in 2008. Under the Stock
Rights Agreement, Nationwide, as successor in interest to Nationwide, as
successor in interest to ALLIED Mutual, is entitled to nominate and the Company
is required to use its best efforts to cause the election or retention of a
number of members of the Company's Board of Directors in proportion to
Nationwide, as successor in interest to ALLIED Mutual's, percentage ownership of
the total number of shares of the Company's voting stock outstanding at the time
of nomination. In addition, the Company is required to elect to its Executive
Committee at least one Company director who has been nominated by Nationwide, as
successor in interest to ALLIED Mutual, but who is not an officer or employee of
Nationwide, as successor in interest to ALLIED Mutual, and the Company must
limit the number of directors serving on the Executive Committee to five at any
time. The Stock Rights Agreement restricts the ability of Nationwide, as
successor in interest to ALLIED Mutual, to grant proxies to other than
affiliated individuals and to solicit other stockholders of the Company.
Nationwide, as successor in interest to ALLIED Mutual shall also be prohibited
from initiating or accepting a tender offer for shares of Common Stock except
under certain conditions. The Company has a right of first refusal with respect
to any sale by Nationwide, as successor in interest to ALLIED Mutual of the
Common Stock subject to certain exceptions, including a distribution of such
stock to the public in a registered public offering or an offering pursuant to
Rule 144. Nationwide, as successor in interest to ALLIED Mutual, has incidental
registration rights and three demand registration rights with respect to the
6.75% Preferred and Common Stock owned by Nationwide, as successor in interest
to ALLIED MUTUAL. The preceding summary of the Stock Rights Agreement is
qualified in its entirety by reference to the full extent of the Stock Rights
Agreement and the amendment thereto, copies of which are filed as Exhibit 14 to
the Form S-1.

         The Company and its affiliates pool their excess cash into a short-term
investment fund pursuant to the Intercompany Cash Concentration Fund Agreement.
The fund, administered by AID Finance Services, Inc. (an affiliate of the
Company), also issues short-term loans (30 days or less) to affiliated companies
in accordance with the current intercompany borrowing policy. At December 31,
1997, $3,468,759 was invested in the fund, which is carried as a short-term
investment. Interest earned from the fund during 1997 was $77,594. The Company
and its affiliates pay to AID Finance Services, Inc. a management fee (5 basis
points of invested assets) which is offset against investment income. Interest
earned by the Company and its subsidiaries from the fund during 1997 was
$477,000. Interest expense paid to AID Finance Services, Inc. during 1997
amounted to $241,420 from affiliates. The preceding summary of the Intercompany
Cash Concentration Fund Agreement is qualified in its entirety by reference to
the full text of the Intercompany Cash Concentration Fund Agreement, a copy of
which is filed as Exhibit 26 to the Schedule 14D-9.

         The Company and its subsidiaries have from time to time borrowed funds
from affiliates as needed on an arms length basis. The Company has entered into
various note payable agreements with ALLIED Mutual. At December 31, 1997, the
outstanding balance of the notes payable was $3,567,722. In 1997, the Company
incurred interest expenses of $241,420 from affiliates.
 
         ALLIED Group paid premiums to the Company for term life insurance on
the ALLIED Group's employee group in the amount of $468,000 in 1997.

         On January 2, 1997, State Street Bank and Trust Company, as the ESOP
Trustee, purchased for the ESOP Trust 19,143 shares of Common Stock from the
Company for $17.50 per share.

         During the year ended December 31, 1997, ALLIED Mutual, the Company and
its subsidiaries paid $1 million in fees and media costs to J.D. Evans &
Associates, of which Julie Evans (daughter of John E. Evans) is a stockholder.

         During 1997, directors and executive officers of the Company purchased
insurance or obtained residential mortgages from the Company or its subsidiaries
on terms comparable to those offered in the normal course of business to
nonaffiliated customers. In addition, corporations of which the Company
directors are executive officers purchased insurance from the Company's
subsidiaries and ALLIED Mutual in the ordinary course of business during 1997.

         Severance Pay Plan. On May 30, 1998, the Compensation Committee of the
Board (the "Compensation Committee"), following publication of the ALLIED Group
Offer and after consideration of the potentially destabilizing effects of the
pendency of such proposal on the morale and retention of Company employees,
approved the adoption by the Company of a severance policy applicable to the
Company's salaried and hourly employees. On June 2, 1998, the Board approved and
ratified the actions of the Compensation Committee. The following is a summary
of the Company's Severance Pay Plan (the "Severance Pay Plan"), which is
qualified in its entirety by reference to the full text of such Plan, a copy of
which is filed as Exhibit 21 to the Schedule 14D-9 filed by ALLIED Life with the
SEC on June 10, 1998 (the "Schedule 14D-9" which term hereinafter includes the
amendments and exhibits thereto) and is incorporated herein by reference.

         The Severance Pay Plan provides for certain benefits to eligible
employees following an involuntary termination of employment or Company-approved
resignation. The benefits consist of a lump sum payment equal to one week's base
salary for each year, or portion thereof, of employment, subject to adjustment
as set forth in the Severance Pay Plan, and continuation of health benefits for
approximately the same period as is used to calculate the lump sum payment.
Benefit continuation terminates when the employee becomes eligible to receive
benefits from another employer. An employee is not eligible to receive severance
benefits if his termination of employment is due to death, transfer of
employment to an affiliate or successor of the Company or for "Cause."

         "Cause" is generally defined as the consistent failure to function as
required by Company standards. In the event an employee's employment terminates
for any reason and the plan administrator subsequently determines that Cause for
termination existed at the time the employee's employment terminated, such
employee shall be deemed to have been terminated for Cause.

         Enhanced benefits are provided to employees who are terminated, whose
employment has been adversely affected, or who resign with the Company's
approval following a change in control. The enhanced benefits consist of an
additional lump sum payment equal to employee's base salary for a period equal
to the greater of three months or from the date of termination of employment
through the first anniversary of the change in control, benefit continuation for
the additional period, and outplacement services to be provided at the expense
of the Company.

         Severance Agreement. In connection with the adoption of the Severance
Pay Plan, the Compensation Committee also approved the entry by, the Company
into separate severance agreements (the "Severance Agreements") with executive
officers and certain employees of the Company.

                                       23
<PAGE>   24
         Each Severance Agreement, the form of which was filed as an Exhibit 
to the Schedule 14D-9, generally provides that in the event of any involuntary
termination or constructive termination of employment (including a material
reduction in responsibilities, a reduction in base pay or incentive compensation
opportunities or an involuntary relocation) within the two (2) year period
following a change in control, an employee who is a party to such an agreement
would receive, in lieu of any other severance, a lump sum payment equal to one
year's base pay plus the employee's highest bonus over the preceding two years
and benefit continuation for twelve (12) months following the termination of
employment (or until the employee becomes eligible for benefits under a new
employer). For a small number of employees, the benefit would be a lump sum
severance payment equal to two times annual base salary plus the employee's
highest bonus over the preceding two (2) years and benefit continuation for
twelve (12) months following the termination of employment (or until the
employee becomes eligible for benefits under a new employer). In the event that
such severance payments would subject the employee to an excise tax imposed
under Section 4999 of the Internal Revenue Code of 1986, as amended (the
"Code"), the amount of the severance otherwise payable will generally be reduced
to avoid the imposition of such excise tax.

         The Company entered into Severance Agreements that provide for a
severance payment equal to two times the employee's base salary plus the higher
bonus over the preceding two years with each of Messrs.
Samuel J. Wells and Wendell P. Crosser.

         The Company entered into Severance Agreements that provide for a
severance payment equal to the employee's base salary plus the higher bonus over
the preceding two years with each of Messrs. Donald J. Iverson, E. Robert Bejcek
and William D. Whitsell. The Company has also entered into such agreements with
two (2) other employees, who are not executive officers.

         The Company has calculated that the maximum aggregate lump sum that
could be payable pursuant to all of the Severance Agreements described above
(including non-executive officers), assuming termination of each of these
individuals, is approximately $1,700,000.

         Amendment to ALLIED Life Employee Stock Ownership Plan. On June 2,
1998, the Board, acting upon the recommendation of the Compensation Committee,
amended the Company's Employee Stock Ownership Plan (the "ESOP") to provide
that participants in the ESOP (including executive officers) will be fully
vested in their accounts upon the occurrence of a "Change in Control" (as
defined below). The amendment also provides that in the event of a Change in
Control, the Company will make an Employer Contribution (as defined in the
ESOP) to the ESOP in the form of cash equal to the value of the Minimum
Required Allocation Amount (as defined in the ESOP) for the then current Plan   
Year (as defined in the ESOP) to be allocated as of the date of such Change in
Control to all participants who are eligible Participants (within the meaning
of the ESOP) as of such date. The amendment to the ESOP is filed as Exhibit 20
to the Schedule 14D-9.

         For purposes of the foregoing, a "Change in Control" is deemed to have
occurred upon the first to occur of the following:

         (i)      Any person or entity, other than the Company, a subsidiary of
                  the Company, or any employee benefit plan of the Company or
                  its subsidiaries, becomes the direct or indirect beneficial
                  owner of the Company's securities having 20 percent or more of
                  the combined voting power of the then outstanding securities
                  of the Company (other than as a result of an issuance of
                  securities initiated by the Company in the ordinary course of
                  business and other than ALLIED Mutual so long as no change in
                  control of ALLIED Mutual within the meaning of Iowa Code
                  Section 521A has occurred); or

         (ii)     As the result of, or in connection with, any cash tender or
                  exchange offer, merger or other business combination, sale of
                  assets or contested election, or any combination of the
                  foregoing transactions, less than 80% of the combined voting
                  power of the then outstanding securities of the Company or any
                  successor corporation or entity entitled to 


                                       24
<PAGE>   25

                  vote generally in the election of directors of the Company or
                  such other corporation or entity after such transaction, are
                  held in the aggregate by holders of the Company's securities
                  entitled to vote generally in the election of directors of the
                  Company immediately prior to such transactions; or

         (iii)    During any period of two (2) consecutive years, individuals
                  who at the beginning of such period constitute the Board plus
                  any new Director (a) whose election by the Board or nomination
                  for election by the Company's shareholders was approved by a
                  vote of at least two-thirds (2/3) of the Directors at the
                  beginning of the period or whose election or nomination for
                  election was previously so approved or (b) whose nomination
                  for election by the Company's shareholders was made pursuant
                  to the Stock Rights Agreement between the Company and ALLIED
                  Mutual, cease for any reason to constitute a majority thereof.
         
         As a result of the purchase by Acquisition Sub of Common Shares in the
Offer, a Change of Control shall be deemed to have occurred for purposes of the
vesting and allocation provisions of the ESOP.

         Amendment to John Evans Consulting Agreement. The consulting agreement
between the Company, ALLIED Mutual, ALLIED Group and John Evans, which is
described in the Schedule 14D-9, was amended on March 24, 1998 to provide for a
decrease in the annual compensation payable to Mr. Evans from $180,000 to
$120,000. Such annual compensation is consideration for consulting services
rendered by Mr. Evans and is prorated among the Company, Nationwide, as
successor in interest to ALLIED Mutual, and ALLIED Group. The consulting
agreement and the amendments thereto are filed as Exhibit 10.25 to the Company's
Annual Report on Form 10-K for the year ended December 31, 1994, Exhibit 10.37
to the Company's Annual Report on Form 10-K for the year ended December 31,
1996, Exhibit 10.42 to the Company's Quarterly Report on Form 10-Q for the
quarter ended June 30, 1997, and Exhibit 10.47 to the Company's Quarterly Report
on Form 10-Q for the quarter ended March 31, 1996.

         Amendment to Short Term Management Incentive Plan. On June 2, 1998, the
Company's Short Term Management Incentive Plan was amended to provide that in
the event of a change of ownership or control, the bonus to be paid to
participants for the year in which such change in ownership or control occurred
shall be the Goal Level Bonus (as provided in the Short Term Management
Incentive Plan) regardless of the actual level of growth or earnings per share.

         Retention Bonus Plan. On June 2, 1998 the Board approved the Company's
Retention Bonus Plan pursuant to which each employee of the Company (excluding
any officer of the Company or ALLIED Life) who remains in the Company's employ
through November 30, 1998 will receive a bonus in an amount equal to such
employee's bi-weekly base salary, to be paid as soon as practicable after
November 30, 1998, but not later than December 15, 1998.

         Treatment of Stock Options; Certain Benefits. The Company has taken all
necessary action so that, effective as of the Effective Time, (i) each
outstanding employee or director stock option (the "Options") to purchase Common
Shares granted under the ALLIED Life Financial Corporation Executive Stock
Option Plan and the ALLIED Life Financial Corporation Long-Term Management
Incentive Plan (the "Option Plans"), whether or not then exercisable or vested,
will become fully exercisable and vested, (ii) cause each Option that is then
outstanding to be cancelled and (iii) in consideration of such cancellation
cause the Company (or, at Nationwide's option, Acquisition Sub) to pay to such
holders of Options an amount in respect thereof equal to the product of (A) the
excess, if any, of the Merger Consideration over the exercise price of each such
Option and (B) the number of Common Shares previously subject to the Option
immediately prior to its cancellation (such payment to be net of withholding
taxes). The Company has agreed to use all commercially reasonable efforts to
ensure that (a) no consent of any holder of an Option is required to effect the
transactions contemplated by Section 2.11 of the Merger Agreement and (b)
following the Effective Time, no Option or any other option, warrant or right
will give any person any right to acquire any securities of the Surviving
Corporation.

          Indemnification and Insurance. From and after the Effective Time,
Nationwide agreed to indemnify and hold harmless each present and former
director and officer of the Company, (when acting in such capacity or as a
member of the Special Committee (as defined in the Merger Agreement)) determined
as of the Effective Time (each, an "Indemnitee" and, collectively, the
"Indemnitees"), against any costs or expenses (including reasonable attorneys'
fees), judgements, fines, losses, claims, damages or liabilities (collectively,
"Costs") incurred in connection with any claim, action, suit, proceeding or
investigation, whether civil, criminal, administrative or investigative, arising
out of matters existing or occurring at or prior to the Effective Time,
including without limitation any and all shareholder lawsuits existing on the
date hereof, to the fullest extent that the Company would have been permitted
under Iowa law and its charter or by-laws in effect on June 3, 1998 to indemnify
such Person (as defined in the Merger Agreement) (and Nationwide has agreed to
advance expenses as incurred to the fullest extent permitted under applicable
law provided the Person to whom expenses are advanced provides a written
affirmation of his or her good faith belief that the standard of conduct
necessary for indemnification has been met, and an undertaking to repay such
advances if it is ultimately determined that such Person is not entitled to
indemnification).

         The Surviving Corporation (as determined in the Merger Agreement) 
shall maintain the Company's existing directors' and officers' liability
insurance ("D&O Insurance") or D&O Insurance that is substantially comparable to
the Company's existing D&O Insurance for a period of two years after the
Effective Time so long as the annual premium therefor is not in excess of 200%
of the last annual premium paid prior to June 3, 1998 (such last annual
premium being hereinafter referred to as the "Current Premium"); provided,
however, that if the then existing D&O Insurance or substantially comparable D&O
Insurance cannot be acquired during the two-year period for not in excess of
200% of the Current Premium, then the Surviving Corporation will obtain as much
D&O Insurance as can be obtained for the remainder of such period for a premium
not in excess (on an annualized basis) of 200% of the Current Premium. If the
D&O Insurance is terminated prior to the end of the sixth anniversary of the
Effective Time, the Surviving Corporation will purchase extended reporting
coverage under D&O Insurance covering claims made during the remainder of such
period with respect to acts which occurred prior to the Effective Time.

CERTAIN REGULATORY MATTERS

         Iowa Approval. The acquisition of control of an Iowa domestic insurer
domiciled in Iowa, such as the Company, requires the approval of the
Commissioner of the Iowa Department of Insurance (the "Iowa Commissioner") under
Section 521A.3 of the Iowa Insurance Law. Section 521A.3 of the Iowa Insurance
Law provides that when a person or entity enters into an agreement to merge with
or otherwise to acquire control of a domestic insurer, the person or entity
shall file with the Iowa Commissioner a statement containing certain specified
information set forth in Section 521A.3(2) of the Iowa Insurance Law (the "Form
A"). The Form A filing must also be sent to the domestic insurer and the
domestic insurer must provide its stockholders with a summary of the information
contained in the Form A. Nationwide filed its Form A concerning the acquisition
of the Company with the Iowa Commissioner on May 19, 1998, and filed amendments
to such Form A filing on July 2, 1998 and July 22, 1998. A summary of the
information contained in the Form A filing (as amended) was also circulated to
the Company's stockholders.

         A hearing to consider the Merger was held before the Iowa Commissioner
on July 29, 1998, and then adjourned and reconvened on August 31, 1998. In its
Findings of Fact and Conclusions of Law dated September 11, 1998, the Iowa
Commissioner formally approved Nationwide's acquisition of the Company.

         Other Insurance Regulatory Approvals. Certain other states may require
that notice be given to, or approval be obtained from, the insurance department
of such state. The Company and Nationwide have agreed to use reasonable efforts
to file any required notices or otherwise to take such actions as are necessary
to obtain any required approvals or to comply with applicable requirements in
connection with the Merger under such laws. Based upon available information,
the Company and Nationwide believe that the Merger can be effected in accordance
with such laws and that no material delay in consummating the Merger will result
therefrom.

         Antitrust. The Antitrust Division of the U.S. Department of Justice
(the "Antitrust Division") and the Federal Trade Commission (the "FTC")
frequently scrutinizes the legality under the antitrust laws of transactions
such as Acquisition Sub's proposed acquisition of the Company. At any time
before or after Acquisition Sub's acquisition of Common Shares pursuant to the
Offer, the Antitrust Division or the FTC could take such action under the
antitrust laws as it deems necessary or desirable in the public interest,
including seeking to enjoin the consummation of the Merger or seeking the
divestiture of Common Shares acquired by Acquisition Sub or the divestiture of
substantial assets of the Company or its subsidiaries or Nationwide or its
subsidiaries. Private parties may also bring legal action under the antitrust
laws under certain circumstances. There can be no assurance that a challenge to
the Offer or the Merger on antitrust grounds will not be made or, if such a
challenge is made, of the result thereof.

LITIGATION

         On December 31, 1997, a petition was filed by Mary M. Rieff ("Rieff"),
an ALLIED Mutual policyholder, in the Iowa District Court in and for Polk
County, Iowa, against ALLIED Group and certain other individuals who are or were
officers and/or directors of ALLIED Mutual and/or ALLIED Group. The Company is
not a party to this proceeding. Rieff filed an amended petition (the "Amended
Petition") on or about June 11, 1998. The Iowa District Court has granted
Nationwide's motion to intervene as a party defendant in this action.

         The Amended Petition, an alleged policyholder derivative and class
action, asserts, among other things, (i) that the defendants were responsible
for the inappropriate transfer of ALLIED Mutual's corporate assets, the seizure
of certain corporate opportunities and the implementation of an improper "de
facto demutualization" without informing or compensating policyholders or
receiving the appropriate approval from regulatory authorities; (ii) that this
allegedly wrongful demutualization began on or about January 1, 1985 and was
accomplished through transfers of ALLIED Mutual's assets to ALLIED Group and to
the individual defendants for inadequate consideration; (iii) that the
individual defendants breached fiduciary duties owed to ALLIED Mutual, wasted
its corporate assets and intentionally interfered with its contracts,
prospective business advantage and business relationships; and (iv) that the
defendants improperly transferred substantial ownership of and control over
ALLIED Group and ALLIED Mutual's 


                                       26
<PAGE>   27
insurance business. These claims were brought on behalf of ALLIED Mutual, which
is named as a nominal defendant.

         The Amended Petition also asserts claims on behalf of a class of ALLIED
Mutual policyholders who have allegedly been deprived of their property by the
"de facto demutualization" of ALLIED Mutual. The class that Rieff seeks consists
of: (i) all ALLIED Mutual policyholders who held ALLIED Mutual policies on or
about February 18, 1993; and (ii) all current ALLIED Mutual policyholders as of
the date of the filing of the original petition who have allegedly been harmed
by higher premiums and/or lower dividends as a result of the "de facto
demutualization" of ALLIED Mutual. The claims that purport to be brought as
class claims assert, among other things, (i) that the defendants were
responsible for the "de facto demutualization" of ALLIED Mutual and that those
actions wrongfully deprived the class of their ownership rights and interests in
ALLIED Mutual's surplus and net worth without proper compensation; (ii) that
this allegedly wrongful demutualization constituted a conversion of ALLIED
Mutual's surplus for the benefit of ALLIED Group and its shareholders, including
the individual defendants; and (iii) that the individual defendants breached
fiduciary duties owed to ALLIED Mutual and intentionally interfered with ALLIED
Mutual's business and contractual relationships.

         The Amended Petition further asserts that as a result of the foregoing,
ALLIED Mutual and the ALLIED Mutual members have suffered damages in
excess of $500 million. The Amended Petition requests an accounting of the
assets allegedly wrongfully transferred to ALLIED Group and compensation to
ALLIED Mutual for the value of such assets, for the seizure of corporate
opportunities and for the de facto demutualization" of ALLIED Mutual. The
Amended Petition also asks for certain other relief, including, among other
things, removal of the directors of ALLIED Mutual, attorneys' fees and costs,
equitable relief and interest, restitution for any assets wrongfully transferred
or conveyed and the distribution to ALLIED Mutual policyholders of surplus in
excess of what is required to be retained in connection with any recovery by
ALLIED Mutual from the defendants.

         On June 11, 1998, Rieff filed an amended motion seeking to enjoin the
defendant directors of ALLIED Mutual from considering, negotiating or approving
any transaction on behalf of ALLIED Mutual with Nationwide or any third party
because of alleged conflicts of interest of the members of the ALLIED Mutual
Board of Directors. That motion was heard by the Iowa District Court on July 16,
1998, and was denied by the Court on July 17, 1998.

         On June 24, 1998, the defendants filed motions to dismiss the Amended
Petition, asserting, among other things, that (i) members of a mutual
insurance company lack standing to maintain a derivative action; (ii) the
Amended Petition fails to state a claim upon which relief can be granted as to
ALLIED Group; (iii) the bulk of the claims in the Amended Petition are barred by
the applicable statute of limitations; (iv) the derivative claims in the Amended
Petition may not be brought as direct or class claims; and (v) the class claims
are barred by the applicable statute of limitations. The motions to dismiss have
been fully briefed, and oral argument was heard on September 28, 1998.

         This suit is in its preliminary stages and the Company cannot assess
its merits at this time.

ACCOUNTING TREATMENT

         The Merger will be accounted for as a purchase of the Company by
Nationwide in accordance with statutory accounting practices, whereby the
purchase price will be allocated based upon the historic statutory book values
of the admitted assets acquired and the statutory liabilities assumed by
Nationwide with the excess being recorded as goodwill.

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

         The following is a summary of material federal income tax consequences
of the Merger to stockholders of the Company. This summary does not purport to
discuss all income tax consequences of the Merger that may be relevant to
particular stockholders in light of their individual circumstances or to certain
types of stockholders subject to special treatment, such as life insurance
companies, tax-exempt organizations and financial institutions, persons who are
not citizens or residents of the United States or 


                                       27
<PAGE>   28
who are foreign corporations, and stockholders who acquired stock through the
exercise of Company stock options or otherwise as compensation.

         The receipt of cash in exchange for Common Shares pursuant to the
Merger, or pursuant to the exercise of dissenters' appraisal rights, will be a
taxable transaction for federal income tax purposes under the Code, and may also
be a taxable transaction under applicable state, local or foreign income or
other tax laws. Generally, for federal income tax purposes, a stockholder will
recognize gain or loss equal to the difference between the amount of cash
received by the stockholder pursuant to the Merger, or exercise of dissenters'
appraisal rights, and the aggregate tax basis in the Common Shares sold by the
stockholder, or with respect to which dissenters' rights are exercised, as the
case may be. Gain or loss will be calculated separately for each block of Common
Shares tendered and purchased pursuant to the Merger, or with respect to which
dissenters' appraisal rights are exercised, as the case may be.

         If Common Shares are held by a stockholder as capital assets, gain or
loss recognized by the stockholder will be capital gain or loss, which will be
long-term capital gain or loss if the stockholder's holding period for the
Common Shares exceeds twelve months. Under present law, long-term capital gains
recognized by an individual stockholder will generally be taxed at a maximum
federal marginal tax rate of 20%, and long-term capital gains recognized by a
corporate stockholder will be taxed at a maximum federal marginal tax rate of
35%. In addition, under present law the ability to use capital losses to offset
ordinary income is limited. Stockholders should consult their tax advisors
regarding the applicable rate of taxation and their ability to use capital
losses against ordinary income.

         A stockholder that surrenders Common Shares pursuant to the Merger (or
pursuant to the exercise of dissenter's rights) may be subject to backup
withholding unless the stockholder provides its taxpayer identification number
("TIN") and certifies that such number is correct or properly certifies that it
is awaiting a TIN, or unless an exemption applies. A stockholder that does not
furnish its TIN may be subject to a penalty imposed by the IRS.

         THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE DOES NOT CONSTITUTE
TAX ADVICE. STOCKHOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS TO DETERMINE
THE PARTICULAR TAX CONSEQUENCES TO THEM (INCLUDING THE APPLICABILITY AND EFFECT
OF THE ALTERNATIVE MINIMUM TAX AND OF ANY STATE, LOCAL OR FOREIGN INCOME AND
OTHER TAX LAWS) OF THE MERGER.

EFFECT OF THE MERGER ON THE COMPANY'S STOCKHOLDERS

         Consummation of the Merger is contingent upon, among other things,
approval of the Merger by the holders of Common Shares and 6.75% Preferred
Shares. In the Merger, each Common Share outstanding on the Effective Date
(other than Common Shares held by Stockholders who perfect their appraisal
rights under Iowa Law, Common Shares then held by Nationwide and Common Shares
held in the Company's treasury) will be converted into the right to receive cash
as part of the Merger. Therefore, as a result of the Merger, the entire equity
interest in the Company will be owned by Nationwide and the Company's current
stockholders will no longer have any equity interest in the Company and will no
longer share in future earnings and growth of the Company, the risks associated
with achieving any such earnings and growth, or the potential to realize greater
value for their shares of stock through divestitures, strategic acquisitions or
other corporate opportunities that may be pursued by the Company in the future.
Instead, each current holder of the Common Shares will have only the right to
receive the Merger Consideration or to seek appraisal rights as described under
"--Dissenting Stockholders' Rights" below.

                                       28
<PAGE>   29

EXCHANGE OF CERTIFICATES AND PAYMENT OF MERGER CONSIDERATION

         Nationwide has selected            as the Paying Agent, with whom it
shall cause Acquisition Sub to deposit, for the benefit of the holders of
Common Shares, cash in an aggregate amount equal to the aggregate Merger
Consideration (the "Payment Fund"). The Merger Agreement provides that, upon
surrender to the Paying Agent of a certificate representing Common Shares for
cancellation, together with a letter of transmittal and such other customary
documents as may be required by the instructions to the letter of transmittal
(collectively, the "Certificate") and acceptance thereof by the Paying Agent,
the holder of such Certificate shall be entitled to receive in exchange therefor
the amount of cash into which the number of Common Shares previously represented
by such Certificate shall have been converted. The Paying Agent shall accept
such Certificate upon compliance with such reasonable terms and conditions as
the Paying Agent may impose to effect an orderly exchange thereof in accordance
with normal exchange practices. If the Merger Consideration (or any portion
thereof) is to be delivered to any person other than the person in whose name
the Certificate representing Common Shares surrendered in exchange therefor is
registered on the record books of the Company, it shall be a condition to such
exchange that the Certificate so surrendered shall be properly endorsed or
otherwise be in proper form for transfer and that the person requesting such
exchange shall pay to the Paying Agent any transfer or other taxes required by
reason of the payment of such consideration to a person other than the
registered holder of the Certificate surrendered, or shall establish to the
satisfaction of the Paying Agent that such tax has been paid or is not
applicable. After the Effective Time, there shall be no further transfer on the
records of the Company or its transfer agent of any Certificate representing
Common Shares and if any such Certificate is presented to the Company for
transfer, it shall be cancelled against delivery of the Merger Consideration as
hereinabove provided. Until surrendered, each Certificate representing Common
Shares (other than a Certificate representing Common Shares to be cancelled),
shall be deemed at any time after the Effective Time to represent only the right
to receive upon such surrender the Merger Consideration, without any interest
therein.

         The Merger Agreement further provides that, promptly after the
Effective Time (but in no event more than five business days thereafter),
Nationwide shall require the Paying Agent to mail to each record holder of
Certificates that immediately prior to the Effective Time represented Common
Shares which have been converted, a letter of transmittal (which shall specify
that delivery shall be effective, and risk of loss and title shall pass, only
upon proper delivery of Certificates representing Common Shares to the Paying
Agent and shall be in such form and have such provisions as Nationwide
reasonably may specify) and instructions for use in surrendering such
Certificates and receiving the Merger Consideration to which such holder shall
be entitled.

         The Merger Consideration paid upon the surrender for exchange of
Certificates representing Common Shares shall be deemed to have been issued and
paid in full satisfaction of all rights pertaining to the Common Shares
theretofore represented by such Certificates, subject, however, to the Surviving
Corporation's obligation (if any) to pay any dividends or make any other
distributions with a record date prior to the Effective Time which may have been
declared by the Company on such Common Shares in accordance with the terms of
the Merger Agreement or prior to the date of the Merger Agreement and which
remain unpaid as of the Effective Time. Any portion of the Payment Fund that
remains undistributed to the holders of the Certificates representing Common
Shares for 120 days after the Effective Time shall be delivered to Nationwide 


                                       29
<PAGE>   30
upon demand, and any holders of Common Shares who have not theretofore complied
with the Merger Agreement requirements shall thereafter look only to Nationwide
and only as general creditors thereof for payment, without interest, of their
claim for any Merger Consideration with respect to their Common Shares.

         None of Nationwide, Acquisition Sub, the Surviving Corporation or the
Paying Agent shall be liable to any person in respect of any cash, shares,
dividends or distributions payable from the Payment Fund delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.
If any Certificates representing Common Shares shall not have been surrendered
prior to seven years after the Effective Time (or immediately prior to such
earlier date on which any Merger Consideration in respect of such Certificate
would otherwise escheat to or become the property of any Governmental Entity),
any such cash, shares, dividends or distributions payable in respect of such
Certificate shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation free and clear of all claims or interest
of any person previously entitled thereto.


DISSENTING STOCKHOLDERS' RIGHTS

         The following discussion is not a complete statement of the law
pertaining to dissenters' rights under the IBCA and is qualified in its entirety
by reference to the full text of Sections 490.1301 through 490.1331 of the IBCA
setting forth the rights of stockholders who object to the Merger. Dissenting
stockholders wishing to exercise such dissenters' rights or to preserve their
rights to do so should review the following discussion and the provisions of
Sections 490.1301 through 490.1331 of the IBCA with counsel. A copy of the
relevant sections of the IBCA is attached to this Information Statement as Annex
II and is incorporated herein by reference. The failure of a dissenting
stockholder to comply in a timely and proper manner with the procedures set
forth in the IBCA will result in its loss of dissenters' rights with respect to
the Merger.

         Sections 490.1301 through 490.1331 of the IBCA set forth the rights of
stockholders of the Company who object to the Merger. Any holder of Common
Shares who does not vote in favor of the Merger (including any such holder who
abstains from voting) and who objects to the Merger may, if the Merger is
consummated, obtain payment, in cash, for the fair market value of such holder's
shares by complying with the requirements of Sections 490.1301 through 490.1331
of the IBCA. "Fair Value" is defined in the IBCA as "the value of the Shares
immediately before the effectuation of the corporate action to which dissenters
object, excluding any appreciation or depreciation in anticipation of the
corporate action unless exclusion would be inequitable." Holders of Common
Shares are not eligible to exercise their dissenters' rights unless they are
stockholders on the Record Date and have not voted in favor of the Merger.

         Before the taking of the vote on the Merger at the Special Meeting,
each dissenting stockholder must file with the Company a written objection to
the Merger stating that the stockholder intends to demand payment in respect of
the shares of any class held by it if the Merger is consummated. A written
objection must be filed with the Company by holders of Common Shares who wish to
dissent even if they vote against the Merger. Such written objections should be
addressed to: Sally J. Malloy, Corporate Secretary, ALLIED Life Financial
Corporation., 701 Fifth Avenue, Department 2003, Des Moines, Iowa 50391-2003.

         Within ten days after the Special Meeting, the Company must provide
written notice (the "Dissenters' Notice") to each dissenting stockholder that
the Merger has been authorized. To exercise dissenters' rights, each dissenting
stockholder must, no sooner than 30 nor later than 60 days after the Dissenters'
Notice was delivered by the Company, mail a written demand for payment for such
dissenting stockholder's Common Shares. Such written demands should be sent to:
Sally J. Malloy, Corporate Secretary, ALLIED Life Financial Corporation., 701
Fifth Avenue, Department 2003, Des Moines, Iowa 50391-2003. Subject to the
following paragraph, at the Effective Time or upon receipt of a payment demand,
whichever occurs later, the Company must pay to each dissenting stockholder the
estimated fair value for such dissenting stockholder's shares, plus accrued
interest.

         In the event that the Company and any dissenting stockholder are unable
to agree as to fair value, the Company must pay the amount demanded unless
within 60 days the Company commences a court proceeding in the district court of
Polk County, Iowa, demanding a determination of the value of the shares


                                       30
<PAGE>   31
of all dissenting stockholders who have not agreed with the Company as to the
fair value of their shares. All dissenting stockholders, whether or not
residents of the State of Iowa, will be parties to any court proceeding that is
commenced by the Company.

         A negative vote on the Merger does not constitute a "written objection"
to be filed by a dissenting stockholder. A dissenting stockholder's abstention
from voting on the Merger or failure to vote on the merger will not constitute a
waiver of such stockholder's rights under Sections 490-1301 through 490.1331 of
the IBCA, provided that a written objection has been properly filed before the
Merger is effected. A vote in favor of the Merger will constitute a waiver of
such stockholder's dissenters' rights, however, even if a written objection has
been filed.
          
         A dissenting stockholder's objections to the Merger or demand for
payment for its shares may be made by facsimile transmission, provided such
facsimile is confirmed by a written objection or demand, as the case may be,
sent by certified or registered mail to the address specified above within 24
hours after transmission of the facsimile. Facsimile communications should be
addressed to: Sally J. Malloy, Corporate Secretary, ALLIED Life Financial
Corporation., 701 Fifth Avenue, Department 2003, Des Moines, Iowa 50391-2003
and the appropriate facsimile connection is to (515) 280-4399.

         For a discussion of the Federal income tax consequences of receipt of
payment for shares upon exercise of dissenters' rights, see "THE MERGER--Certain
United States Federal Income Tax Consequences."

                              THE MERGER AGREEMENT

         The following is a summary of the terms and conditions of the Merger
Agreement. Any references to the Merger Agreement set forth below or included
elsewhere in this Information Statement are qualified in their entirety by
reference to the Merger Agreement (attached hereto as Annex I), which is
incorporated herein by reference. Terms that are not otherwise defined in this
summary shall have the meanings set forth in the Merger Agreement. Stockholders
are strongly advised to read the Merger Agreement in its entirety prior to
voting.

THE OFFER

         In the Merger Agreement, Nationwide agreed, subject to certain
conditions, and among other things, to offer $30.00 per Common Share, net to the
seller in cash without interest. The Offer expired at 5:00 p.m., New York City
time, on September 30, 1998. Having been satisfied that the Minimum Condition
(as defined in the Offer), the Insurance Regulatory Condition (as defined in the
Offer), and other certain conditions with respect to the Offer had been met,
Acquisition Sub timely accepted for payment, and paid for, all Common Shares
validly tendered and not withdrawn pursuant to the Offer.

THE MERGER

         The Merger Agreement provides that, following the satisfaction or
waiver of the conditions set forth therein, Acquisition Sub will be merged with
and into the Company, with the Company continuing as the surviving corporation,
and each Common Share then outstanding (other than Common Shares then owned by
Nationwide or Acquisition Sub, Common Shares held as treasury shares by the
Company and Dissenting Shares) will, by virtue of the Merger and without any
action by the holder thereof, be converted into the right to receive $30.00 per
Common Share, net to the seller in cash, without interest thereon, upon the
surrender to the Paying Agent of a certificate representing Common Shares, for
cancellation, together with a letter of transmittal and such other customary
documents as may be required by the instructions to the letter of transmittal
(collectively, the "Certificate") of the Certificate formerly representing such
Common Shares.

EFFECTIVE TIME OF THE MERGER

         Subject to the conditions set forth in the Merger Agreement, the Merger
shall become effective (the "Effective Time") upon the last to occur of (a) the
filing of the Certificate of Merger with the Ohio Secretary of State, (b) the
filing of the Articles of Merger as required by Iowa law and the recording in
the offices of the register of deeds of the counties in the State of Iowa in
which the principal offices of 


                                       31
<PAGE>   32
Nationwide and the Company are located and (c) such later time as the parties
designate in such filings. The parties to the Merger Agreement agreed to use all
reasonable efforts to assure that the filings contemplated by the Merger
Agreement are made, and the Effective Time occurs, as soon as practicable.


DISSENTING STOCKHOLDERS' RIGHTS

         The Merger Agreement provides that any Common Shares outstanding
immediately prior to the Effective Time and held by a holder who has not voted
in favor of the Merger or consented thereto in writing and who has demanded
properly in writing appraisal for such Common Shares in accordance with Sections
490.1301 through 490.1331 of the IBCA and who has not withdrawn such demand or
otherwise forfeited appraisal rights ("Dissenting Shares") will not be converted
into or represent the right to receive the Merger Consideration. Such
shareholders shall be entitled to receive payment of the appraised value of such
Common Shares held by them in accordance with the IBCA, except that all
Dissenting Shares held by shareholders who shall have failed to perfect or who
effectively shall have withdrawn or lost their rights to appraisal of such
Common Shares held by them under the IBCA shall thereupon be deemed to have been
converted into and to have become exchangeable, as of the Effective Time, for
the right to receive, without any interest thereon, the Merger Consideration,
upon surrender of the Certificate or Certificates that formerly evidenced such
Common Shares. The Company has agreed to give Nationwide prompt notice of any
demands of appraisal received by the Company, withdrawals of such demands, and
any other instruments served pursuant to the IBCA and received by the Company,
and Nationwide shall have the right to participate in all negotiations and
proceedings with respect to such demands. The Company has further agreed that,
prior to the Effective Time, it shall not, except with the prior written consent
of Nationwide, make any payment with respect to any demands for appraisal, or

PROHIBITION ON SOLICITATION

         Pursuant to the Merger Agreement, the Company has agreed that, subject
to certain exceptions, it will not, and will not permit or cause any of its
subsidiaries or any of the officers or directors of it or its subsidiaries to,
and shall direct its and its subsidiaries' employees, agents and representatives
(including any investment banker, attorney or accountant retained by it or any
of its subsidiaries) not to, directly or indirectly, initiate, solicit,
encourage or otherwise facilitate any inquiries or the making of any proposal or
offer with respect to a merger, reorganization, share exchange, consolidation or
similar transaction involving, or any purchase of 15 percent or more of the
assets or any equity securities of, the Company or any of its Significant
Subsidiaries (as defined in Regulation S-X promulgated by the SEC) other than as
set forth in the Company Disclosure Letter, or any other business combination
(any such proposal or offer, an "Acquisition Proposal").

         The Merger Agreement further provides that the Company will not, and
will not permit or cause any of its subsidiaries or any of the officers and
directors of it or its subsidiaries to, and shall direct its and its
subsidiaries' employees, agents and representatives (including any investment
banker, attorney or accountant retained by it or any of its subsidiaries) not
to, directly or indirectly, engage in any negotiations concerning, or provide
any confidential information or data to, or have any discussions with, any
person relating to an Acquisition Proposal, whether made before or after the
date of the Merger Agreement, or otherwise facilitate any effort or attempt to
make or implement an Acquisition Proposal; provided, however, that nothing
contained in the Merger Agreement shall prevent the Company or its Board of
Directors from (i) complying with Rule 14e-2 promulgated under the Exchange Act
with regard to an Acquisition Proposal or (ii) at any time after 180 days from
the date of the Merger Agreement if the Merger shall not by such date have been
approved by the requisite vote of the Company's shareholders or (iii) at any
time after one year from the date of the Merger Agreement if the Merger shall
not by such date have been approved by the Commissioner of Insurance of the
State of Iowa (A) providing information in response to a request therefor by a
Person who has made an unsolicited bona fide written Acquisition Proposal if the
Board of Directors receives from the Person so requesting such information an
executed confidentiality agreement on terms substantially equivalent to those
contained in the Confidentiality Agreement dated as of May 28, 1998 among
Nationwide, Acquisition Sub and the Company (the "Confidentiality Agreement");
(B) engaging in any negotiations or discussions with any Person who has made an
unsolicited bona fide written Acquisition Proposal; or (C) recommending such an
Acquisition Proposal to the shareholders of the Company, if and only to the
extent that, (i) in each such case referred to in clause (A), (B) or (C) above,
the Board of Directors of the Company determines in good faith after
consultation with outside legal counsel that such action is necessary in order
for its directors to comply with their respective fiduciary duties under
applicable law and (ii) in each case referred to in clause (B) or (C) above, the
Board of Directors of the Company determines in good faith (after consultation
with its financial advisor) that such Acquisition Proposal, if accepted, is
reasonably likely to be consummated, taking into 


                                       35
<PAGE>   36
account all legal, financial and regulatory aspects of the proposal and the
Person making the proposal and would, if consummated, result in a more favorable
transaction than the transaction contemplated by the Merger Agreement, taking
into account the long-term prospects and interests of the Company and its
shareholders. The Company will immediately cease and cause to be terminated any
then existing activities, discussions or negotiations with any parties conducted
prior to the date of the Merger Agreement with respect to any of the foregoing.
The Company agreed that it will take the necessary steps to promptly inform the
individuals or entities referred to in the first sentence hereof of the
obligations undertaken in this paragraph and under the Merger Agreement. The
Company will notify Nationwide immediately if any such inquiries, proposals or
offers are received by, any such information is requested from, or any such
discussions or negotiations are sought to be initiated or continued with, any of
its representatives indicating, in connection with such notice, the name of such
Person and the material terms and conditions of any proposals or offers and
thereafter shall keep Nationwide informed, on a current basis, on the status and
terms of any such proposals or offers and the status of any such negotiations or
discussions.


STOCKHOLDER APPROVAL

         Because Nationwide and Acquisition Sub control more than 50% of the
votes represented by the Shares, there is no need to solicit proxies from other
Company shareholders. Accordingly, this Information Statement has been prepared
in lieu of a proxy statement.

ACCESS TO INFORMATION

         Pursuant to the Merger Agreement, subject to applicable law, the
Company shall (a) afford to Nationwide's and Acquisition Sub's accountants,
legal counsel and other advisors ("Representatives") full access during normal
business hours through the period immediately prior to the Effective Time to all
of its and the ALLIED Subsidiaries' (as defined in the Agreement) assets, books,
contracts, commitments and records (including, but not limited to, Tax Returns),
and (b) during such period, the Company shall furnish promptly to Nationwide and
Acquisition Sub all such information concerning its business, assets and
personnel or those of any of its Affiliates, in either clause (a) or (b), as
Nationwide or Acquisition Sub may reasonably request. Information provided by
the Company shall be kept confidential by Nationwide and Acquisition Sub and
shall not be disclosed


                                       36



<PAGE>   37
unless such information (1) was known to Nationwide or Acquisition Sub or was in
their possession prior to the date of the Merger Agreement and was not
identified by the Company as being confidential, (2) is or becomes generally
available to the public other than by unauthorized disclosure by Nationwide or
Acquisition Sub, (3) becomes available to Nationwide or Acquisition Sub from a
third party authorized to make such disclosure, (4) is independently developed
by Nationwide or Acquisition Sub, or (5) is required to be disclosed by law or
by court order.

REASONABLE EFFORTS

         Each of the parties to the Merger Agreement agreed to use all
reasonable efforts to take, or cause to be taken all action, to do, or cause to
be done, and to assist and cooperate with the other parties in doing or causing
to be done, all things necessary, proper or advisable to consummate and make
effective, in the most expeditious manner practicable, the transactions
contemplated by the Merger Agreement, including, but not limited to, (i) the
holding of the Shareholders Meeting and the preparation of the Proxy Statement,
(ii) the obtaining of all Governmental Approvals, and all other necessary
actions or nonactions, waivers, consents and approvals from all appropriate
Governmental Entities and other Persons and the making of all necessary
registrations and filings, (iii) the obtaining of the opinions and certain other
documents referred to in the Merger Agreement, (iv) the resolution of all
organizational and human resources issues relating to the transactions
contemplated by the Merger Agreement, (v) the obtaining or making of all
Consents, Environmental Permits, Filings or Licenses necessary or desirable to
ensure that the Business of the Surviving Corporation may be conducted without
disruption consistent with the past practice of each of the Constituent
Companies and (vi) the defending of any Legal Proceedings challenging the Merger
Agreement or the consummation of the transactions contemplated thereby, the
defense of which shall, at the request of either the Company or Nationwide, be
conducted jointly by Nationwide and the Company on a basis that is satisfactory
to both the Company and Nationwide. The Company grants Nationwide the right to
decide for purposes of the Form A regulatory hearings whether to submit
regulatory applications for the Company, ALLIED Group and ALLIED Mutual
concurrently or separately, and whether to conduct the regulatory hearing and
approval process concurrently or separately for each of the Company, ALLIED
Group and ALLIED Mutual. Both the Company and Nationwide agreed to use all
reasonable efforts to coordinate and cooperate during the regulatory approval
process.


BOARD OF DIRECTORS; CORPORATE GOVERNANCE

         The Merger Agreement provides that, promptly upon acceptance for
payment of the Common Shares by Acquisition Sub pursuant to the Offer,
Acquisition Sub shall be entitled to designate such number of directors on the
Board of Directors of the Company as will give Acquisition Sub, subject to
compliance with Section 14(f) of the Exchange Act, a majority of such directors,
and the Company shall, at such time, cause Acquisition Sub's designees to be so
elected by its existing Board of Directors and each Subsidiary of the Company
and each committee of the Board of Directors of the Company and each such
Subsidiary as will give Acquisition Sub a majority of such directors or
committee, and the Company shall, at such time, cause Acquisition Sub's
designees to be so elected. Subject to applicable law, the Company shall take
all action requested by Nationwide necessary to effect any such election. In
connection with the foregoing, the Company anticipates that at least a majority
of the Board will submit resignations on or after October 1, 1998, and that
contemporaneously the Acquisition Sub Designees (other than Mr. Andersen, who
was already a member of the Board) will occupy a majority of the Board.

See Information Statement Pursuant to Section 14(f) of the Securities Exchange 
Act of 1934 and Rule 14F-1 thereunder filed by the Company on June 10, 1998.

TREATMENT OF STOCK OPTIONS; CERTAIN BENEFITS

         The Company has taken all necessary action so that, effective as of the
Effective Time, (i) each outstanding employee or director stock option (the
"Options") to purchase Common Shares granted under the ALLIED Life Financial
Corporation Executive Stock Option Plan and the ALLIED Life Financial
Corporation Long-Term Management Incentive Plan (the "Option Plans"), whether or
not then exercisable or vested, will become fully exercisable and vested, (ii)
each Option that is then outstanding to be cancelled and (iii) in consideration
of such cancellation the Company (or, at Nationwide's option, Acquisition Sub)
will pay to such holders of Options an amount in respect thereof equal to the
product of (A) the excess, if any, of the Merger Consideration over the exercise
price of each such Option and (B) the number of Common Shares previously subject
to the Option immediately prior to its cancellation (such payment to be net of
withholding taxes). The Company has agreed to use all commercially reasonable
efforts to ensure that (a) no consent of any holder of an Option is required to
effect the transactions contemplated by Section 2.11 of the Merger Agreement and
(b) following the Effective Time, no Option or any other option, warrant or
right will give any person any right to acquire any securities of the Surviving
Corporation.

INDEMNIFICATION AND INSURANCE

         From and after the Effective Time, Nationwide agrees that it will
indemnify and hold harmless each present and former director and officer of the
Company, (when acting in such capacity or as a member of the Special Committee)
determined as of the Effective Time (each, an "Indemnitee" and, collectively,
the "Indemnitees"), against any costs or expenses (including reasonable
attorneys' fees), judgements, fines, losses, claims, damages or liabilities
(collectively, "Costs") incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of matters existing or occurring at or prior to the
Effective Time, including without limitation any and all shareholder lawsuits
existing on the date hereof, to the fullest extent that the Company would have
been permitted under Iowa law and its charter or by-laws in effect on the date
hereof to indemnify such Person (and Nationwide has agreed to advance expenses
as incurred to the fullest extent permitted under applicable law provided the
Person to whom expenses are advanced provides a written affirmation of his or
her good faith belief that the standard of conduct necessary for indemnification
has been met, and an undertaking to repay such advances if it is ultimately
determined that such Person is not entitled to indemnification).

         The Surviving Corporation shall maintain the Company's existing
directors' and officers' liability insurance ("D&O Insurance") or D&O Insurance
that is substantially comparable to the Company's existing D&O Insurance for a
period of two years after the Effective Time so long as the annual premium
therefor is not excess of 200% of the last annual premium paid prior to the date
hereof (such last annual premium being hereinafter referred to as the "Current
Premium"); provided, however, that if the existing D&O Insurance or
substantially comparable D&O Insurance cannot be acquired during the two-year
period for not in excess of 200% of the Current Premium, then the Surviving
Corporation will obtain as much D&O Insurance as can be obtained for the
remainder of such period for a premium not in excess (on an annualized basis) of
200% of the Current Premium. If the D&O Insurance is terminated prior to the end
of the sixth anniversary of the Effective Time, the Surviving Corporation will
purchase extended reporting coverage under D&O Insurance covering claims made
during the remainder of such period with respect to acts which occurred prior to
the Effective Time.

CONDITIONS TO THE MERGER

         The respective obligation of each party to the Merger Agreement to

<PAGE>   39
the respective stockholders of the Company at the Shareholders Meeting called
for such purpose; and (c) the waiting period applicable to the consummation of
the Merger under the Hart-Scott Rodino Antitrust Improvements Act of 1976 shall

Agreement, all Governmental Approvals and other Consents or Filings which the
parties have agreed are required to be obtained prior to the Effective Time
shall have been obtained and not rescinded or adversely modified or limited, if
merely required to be filed, such filings shall have been made and accepted, and
all waiting periods prescribed by applicable Law shall have expired or been
terminated in accordance with applicable Law; provided that no such Governmental
Approval or other Consent or Filing shall contain any conditions or limitations
that compel or seek to compel the Surviving Corporation to dispose of or to hold
separately all or any material portion of the Business or Assets of the parties
and their respective Subsidiaries taken as a whole or that impose or seek to
impose any material limitation on the ability of the Surviving Corporation and
the Company subsidiaries, taken as a whole, to conduct its Business or own its
Assets after the Effective Time in substantially the same manner as the parties
and their respective Subsidiaries presently conduct their Business or own their
Assets; and (d) no order entered or Law promulgated or enacted by any
governmental entity shall be in effect which would prevent the consummation of
the Merger or any other material transactions completed by the Merger Agreement,
and no proceeding brought by a governmental entity shall have been commenced and
be pending which seeks to restrain, enjoin, prevent, or materially delay or
restructure the Merger or any other material transactions contemplated by the
Merger Agreement.

TERMINATION

         The Merger Agreement may be terminated and the Merger abandoned at any
time prior to the Effective Time, whether before or after approval of the Merger
by the stockholders of Nationwide or of ALLIED: (a) by mutual consent of
Nationwide and the Company; (b) by Nationwide if the Board withdraws its
recommendation to the Company's stockholders to approve the Merger; (c) by
Nationwide or the Company if consummation of the Merger is barred by a permanent
injunction which is final and non-appealable; (d) by the Company if, prior to
the purchase of Common Shares pursuant to the Offer, there is an Acquisition
Proposal which the Board determines represents a more favorable transaction to
the Company and its stockholders than the transactions contemplated by the
Merger Agreement, and if the Board, after consultation with outside counsel,
shall have determined that failure to terminate the Merger Agreement is
reasonably likely to be inconsistent with the fiduciary duties of the Board of
the Company under applicable Law and the Company has given Nationwide three
business days notice of the terms of such Acquisition Proposal and has paid
Nationwide the fee contemplated by Section 8.2(b) of the Merger Agreement; (e)
by the Company prior to the completion of the Offer, upon a material breach of
any representation or warranty of Nationwide or Nationwide's failure to comply
in any material respect with any of its covenants or agreements, or if any
representation or warranty of Nationwide or Acquisition Sub shall be or become
untrue in any material respect, which breach or failure to comply or untruth is
not curable or, if curable, is not cured within 30 business days after written
notice thereof has been given to Nationwide; (f) by Nationwide prior to the
completion of the Offer, upon (i) a material breach of any representation or
warranty of the Company or if any representation or warranty of ALLIED shall be
or become untrue in any material respect, which breach or failure to comply or
untruth is not curable or, if curable, is not cured within 30 business days
after written notice thereof has been given to the Company, or (ii) the
Company's failure to comply in any material respect with any of its covenants or
agreements (materiality being construed in light of the transactions
contemplated by the Merger Agreement); or (g) by Nationwide or by the Company,
if Common Shares shall not have been purchased pursuant to the Offer by December
31, 1998 provided that such right to terminate the Merger Agreement shall not be
available to a party whose failure to fulfill any obligation under the Merger
Agreement has been the cause of the failure of such purchase to occur by such

         The Merger Agreement provides that, if the Merger is not consummated,
all costs and expenses incurred in connection with the Merger Agreement and the
transactions contemplated thereby shall be paid by the party incurring such
costs or expenses, except for expenses incurred in connection with the printing,
mailing and solicitation of proxies from shareholders and all filing fees and
related expenses which shall be borne equally by Nationwide and the Company.

         Notwithstanding the foregoing provisions, as described under
"Prohibition on Solicitation", above, if prior to the purchase of Common Shares
pursuant to the Offer, there is an Acquisition Proposal which the Board of
Directors determines represents a more favorable transaction to the Company and
its stockholders than the transactions contemplated by the Merger Agreement, and
if the Board, after consultation with outside counsel, shall have determined
that failure to terminate the Merger Agreement is reasonably likely to be
inconsistent with the fiduciary duties of the Board under applicable Law, the
Company may terminate the Merger Agreement. If the Company so elects to
terminate the Merger Agreement, the Company shall, immediately prior to any such
termination, pay a termination fee in an amount equal to all of the expenses
incurred by Nationwide in connection with this Merger Agreement, the
negotiations leading to its execution, the examination and investigation of the
Company, the preparations and negotiation of the Merger Agreement and related
agreements, and in all other ways related to the Merger, including, but not
limited to, all fees and expenses incurred by investment bankers, accountants,
attorneys and other agents, plus the sum of $3 million in cash (the "Termination
Payment") as liquidated damages and not as a penalty, immediately upon such
termination, in same-day funds, provided that Nationwide shall not be in
material breach of its obligations under the Merger Agreement. Moreover, the
Company shall pay the Termination Payment if the Closing does not occur either
(i) due to the Company's failure to satisfy a condition over which it has sole
control prior to December 31, 1998; or (ii) because prior to December 31, 1999,
the Company or any Subsidiary or affiliate of the Company or any of their
respective shareholders publicly announces, enters into a letter of intent
relating to, enters into a definitive agreement providing for, or consummates, a
transaction, which, as announced, or as provided in such letter or agreement or
as consummated, provides for or relates to the disposition of a controlling
interest in the Company or the sale, transfer or other distribution of assets
constituting a majority (measured by fair market value) of the consolidated
assets of the Company.

         The Company will also pay a termination fee following the termination
of the Merger Agreement by Nationwide (i) following a withdrawal by the Board of
its recommendation that the stockholders approve the Merger Agreement (other
than if the recommendation is withdrawn because the conditions to the
consummation of the Merger cannot be fulfilled for any reason other than a
breach by the Company), or (ii)(A) by virtue of an uncured breach of
representation or warranty by the Company or (B) the Company's failure to comply
in any material respect with any of its covenants or agreements.

AMENDMENT

         The Merger Agreement may be amended by the parties thereto at any time
before or after the approval of the Merger Agreement by the stockholders of
Nationwide or of the Company, but after such 


                                       39
<PAGE>   40
approval no amendment or modification shall be made which in any way materially
adversely affects the rights of such shareholders without the further approval
of such shareholders. Any amendment, modification or material waiver of the
Merger Agreement shall be subject to approval of the Ohio Superintendent and the
Iowa Commissioner. The Merger Agreement may not be amended, modified or
supplemented except by written agreement of the parties thereto.

PLANS FOR THE COMPANY

         Nationwide believes that, in the aggregate, the Merger will result in
increased growth and investment in the Company and its operations. Except as
indicated in this Information Statement and based upon publicly available
information, neither Nationwide nor Acquisition Sub has any present plans or
proposals which relate to or would result in an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving the
Company or any of its subsidiaries, a sale or transfer of a material amount of
assets of the Company or any of its subsidiaries or any material change in the
Company's capitalization or dividend policy or any other material changes in the
Company's corporate structure or business.

GOING PRIVATE TRANSACTIONS

         The SEC has adopted Rule 13e-3 under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), which is applicable to certain "going
private" transactions. Acquisition Sub does not believe that Rule 13e-3 will be
applicable to the Merger unless the Merger is consummated after September 30,
1999, one year after the expiration of the Offer. If applicable, Rule 13e-3
requires, among other things, that certain financial information concerning the
fairness of the Merger and the consideration offered to minority stockholders in
such transaction be filed with the SEC and disclosed to stockholders prior to
the consummation of the Merger.

DIVIDENDS AND DISTRIBUTIONS

         The Merger Agreement provides that the Company shall not make any
change in its dividend practices or policies. The Merger Agreement further
provides that in the event that the Company changes the number of Common 
Shares issued and outstanding prior to the Effective Time as a result of a
reclassification, stock split (including a reverse split), stock dividend or
distribution, recapitalization, merger, subdivision or other similar
transaction, the Merger Consideration shall be equally adjusted.

(1)      The Company and Nationwide, as successor in interest to ALLIED Mutual,
         are parties to a Stock Rights Agreement which expires in 2008. Under
         the Stock Rights Agreement, Nationwide is entitled to nominate and the
         Company is required to use its best efforts to cause the election or
         retention of a number of members of the Company's Board of Directors in
         proportion to Nationwide's percentage ownership of the total number of
         shares of the Company's voting stock outstanding at the time of
         nomination. In addition, the Company is required to elect to its
         Executive Committee at least one Company director who has been
         nominated by Nationwide but who is not an officer or employee of
         Nationwide, and the Company must limit the number of directors serving
         on the Executive Committee to five at any time. The Stock Rights
         Agreement restricts the ability of Nationwide to grant proxies to other
         than affiliated individuals and to solicit other stockholders of the
         Company. Nationwide also is prohibited from initiating or accepting a
         tender offer for Common Shares except under certain conditions. The
         Company has a right of first referral with respect to any sale by
         Nationwide of the Common Shares, subject to certain exceptions,
         including distribution of such shares to the public in a registered
         public offering or an offering pursuant to Rule 144. Nationwide has
         incidental registration rights and three demand registration rights
         with respect to the Preferred Shares.

         The table below sets forth information provided by the individuals
named therein as to the amount of the Company's Common Stock and ESOP Preferred
beneficially owned by the directors and executive officers of the Company,
individually, and the directors and executive officers as a group, all as of
September 1, 1998. The issued and outstanding Common Stock, Series A ESOP
Convertible Preferred Stock with no par value and 6.75% Preferred as of
September 1, 1998 were 4,403,172 shares, 112,863 shares and 2,882,060 shares,

required to be filed with or submitted to the appropriate regulatory
authorities, except for such filings or submissions, the failure to so file or
submit is not, individually or in the aggregate, reasonably likely to have a
Material Adverse Effect.

                  Each Allied SAP Statement complied (and, as to SAP Statements
filed after the date of this Agreement, will comply) in all material respects
with all applicable Laws when so filed, and all material deficiencies with
respect to any such Allied SAP Statement, of which Allied has Knowledge, have
been cured or corrected. Each Allied SAP Statement (and the notes related
thereto) referred to in Section 4.5(a), (b), and (d) hereof was prepared (and,
as to SAP Statements filed after the date of this Agreement, will be prepared)
in accordance with SAP and presents (and, as to SAP Statements filed after the

excess of $250,000, there are no Proceedings pending or, to the Knowledge of
Allied or any of the Allied Subsidiaries, threatened against Allied or any
Allied Subsidiary before any Governmental Entity or arbitrator which,
individually or in the aggregate, are reasonably likely to have a Material
Adverse Effect. Neither Allied nor any Allied Subsidiary is subject to any
Order, except for Orders which, individually or in the aggregate, are not
reasonably likely to have a Material Adverse Effect.

                    (a) Except as set forth in the Allied Disclosure Schedule,
to the Knowledge of Allied, neither Allied nor any Allied Subsidiary is in
violation (or, with notice or lapse of time or both, would be in violation) of
any term or provision of any Law applicable to it or any of its Assets, the
violation of which is, individually or in the aggregate with all other such
violations, reasonably likely to have a Material Adverse Effect. Allied has made
available to Nationwide all reports (including draft reports) of examinations of
the affairs of Allied (including market conduct examinations) issued by
insurance Governmental Entities for any period ending on a date on or after
January 1, 1993; except as set forth in the Allied Disclosure Schedule, all

substantial compliance in all material respects with all applicable
Environmental Laws, which compliance includes, but is not limited to, the
possession of all Environmental Permits required under Environmental Laws and
compliance with the terms and conditions thereof, other than such Allied Real

that Allied or any Allied Subsidiary or any Allied Real Property (including any
owner or operator thereof) is not in such compliance, and, to the Knowledge of
Allied, there are no circumstances that are reasonably likely to prevent or
interfere with such compliance in the future, except to the extent that such
noncompliance is not reasonably likely to have a Material Adverse Effect. To the
Knowledge of Allied, neither Allied nor any Allied Subsidiary has been notified
in writing by any Governmental Entity that any such Environmental Permit will be
modified, suspended or revoked or cannot be renewed or transferred in the
ordinary course of business consistent with past practice or in connection with

Adverse Effect.

                    (b) Except as set forth in the Allied Disclosure Schedule,
there is no Environmental Claim pending or, to the Knowledge of Allied,
threatened against Allied, any Allied Subsidiary, any Allied Real Property
(including any owner or operator thereof) or any Person whose Liability for any

spills, leaks or discharges of Hazardous Substances at, from or to any Allied
Real Property (other than those properties set forth in the Allied Disclosure
Schedule) or any other property which is reasonably likely to require Allied or
any Allied Subsidiary to undertake investigation, abatement, removal, remedial,
corrective or other response action pursuant to applicable Environmental Laws
which investigation, abatement, removal, remediation, corrective or other
response action is reasonably likely to result in a Material Adverse Effect. To
the Knowledge of Allied, none of the Allied Real Property (i) is listed or
proposed for listing on any list maintained by any Governmental Entity of sites
that may require investigation, abatement, removal, remedial, corrective or
other response action pursuant to applicable Environmental Laws, including, but

removal, remedial, corrective or other response action pursuant to applicable
Environmental Laws.

                    (d) Except as set forth in the Allied Disclosure Schedule,

                    (b) Each insurance policy or certificate form, as well as
any related application form, written advertising material and rate or rule
currently marketed by Allied, the use or issuance of which requires filing or
approval, has been appropriately filed, and if required, approved by the
insurance regulatory authorities of any state in which such policies and forms
are required to be filed, except where the failure to make any such filing or
receive any such approval would not be reasonably expected to have a Material
Adverse Effect. To the Knowledge of Allied, all such policies and certificates,
forms, applications, advertising materials and rates or rules are in compliance
in all material respects with all applicable Laws;

                    (c) Since January 1, 1994, all claims and benefits claimed

dividends or distributions on their policies (other than accruals of interest on
cash values or as claim benefits) or otherwise share in the benefits, revenue or
profits of Allied, provided that the practice in certain instances of making
dividends based upon policyholder loss experience or favorable earnings
experience shall not violate the representation contained in this sentence.

pay commissions upon the renewal of any insurance policy nor is it a party to

filed all material reports, statements, documents, registrations, filings or

authority of the jurisdiction where issued and utilize premium rates which if

reinsurance, coinsurance or other similar agreement with Allied is in default
thereunder, except for such





                                       26

or broker, at the time such agent or broker wrote, sold or produced business for

particular jurisdiction in which such agent or broker wrote, sold or produced
such business for Allied, and (ii) no such insurance agent or broker violated

Subsidiary and that have been issued to Allied or any Allied Subsidiary. To the
Knowledge of Allied, all such insurance is in full force and effect and is with
financially sound and reputable insurers. To the Knowledge of Allied or any of
the Allied Subsidiaries, all notices of reportable incidents with respect to
such insurance occurring during the last five years have been given in writing
to appropriate carriers on a basis sufficiently timely to preserve the right of
recovery of such insurance, except where the failure for such incident to be
covered by insurance would not be reasonably likely to have a Material Adverse
Effect. Except as set forth in the Allied Disclosure Schedule, to the Knowledge
of Allied or of any of the Allied Subsidiaries, no party to any Insurance
Contract has stated an intent or threatened to terminate or materially increase
the premium in respect of any such Insurance Contract.

of Allied, no claim has ever been made by an authority in a jurisdiction where

Allied Subsidiary may be subject to taxation by that jurisdiction, except where
any Taxes that would be owed to such jurisdiction would not be reasonably likely

written proposals for the assessment of any Taxes have been proposed, asserted
or assessed in writing against Allied or any of the Allied Subsidiaries by any
taxing authority;

                           (g) No Proceedings are presently pending with regard
to any Taxes or Tax Returns of Allied or any Allied Subsidiary. Allied has no
Knowledge of any threatened Proceeding with respect to any such Taxes or Tax
Returns.

                           (h) No power of attorney currently in force has been
granted by Allied or any Allied Subsidiary with respect to any matter relating
to Taxes;

                           (i) Neither Allied nor any Allied Subsidiary has

reports received from any taxing authority relating to any Tax Return filed by
Allied or any Allied Subsidiary;

                           (k) None of Allied or any Allied Subsidiary is a
party to any Tax allocation or sharing agreement with any Person. None of Allied
or any Allied Subsidiary has

<PAGE>   73



any liability for Taxes of any Person other than Allied or an Allied Subsidiary
under Treasury Regulation Section 1.1502-6 (or any similar provision of state,
local or foreign Law), as a transferee or successor, by Contract or otherwise;

                           (l) Neither Allied nor any Allied Subsidiary is a
party to any Contract or arrangement that, separately or in the aggregate,
could, by reason of the transactions contemplated by this Agreement, give rise
to the payment of any "excess parachute payment" within the meaning of Section
280G of the Code;

                           (m) Neither Allied nor any Allied Subsidiary has
taken any action or has any Knowledge of any fact or circumstance relating to
Allied or any Allied Subsidiary that is reasonably likely to adversely affect
the status of the Merger as a reorganization under Section 368 of the Code; and

                           (n) Neither Allied nor any Allied Subsidiary has

in the Allied Disclosure Schedule and (ii) the Amendment and Settlement of

Excess Benefit Plan Trust, dated as of March 1, 1990, created thereunder (the
"Rabbi Trust"), and of which John E.
Evans and James D. Kirkpatrick are participants.

                  Section 4.19 INTELLECTUAL PROPERTY. Allied and each Allied
Subsidiary owns or otherwise has rights to use, free and clear of all Liens, all
Intellectual Property used in their respective businesses as currently
conducted; and the consummation of this transaction will not result in the loss
of any rights. The use of the Intellectual Property will not infringe or
otherwise violate the rights of any Person and no Person is challenging,
infringing on or otherwise violating any right with respect to the Intellectual
Property.

                  Section 4.20 RATING AGENCIES. Except as disclosed in the

                                    ARTICLE V

                  REPRESENTATIONS AND WARRANTIES OF NATIONWIDE

                  Nationwide represents and warrants to Allied as follows:

                  Section 5.1 ORGANIZATION AND QUALIFICATION. Nationwide is a
mutual insurance company duly organized, validly existing and in good standing
under the Laws of the State of Ohio and has the requisite corporate power and
authority to conduct its Business as it is currently being conducted. Each of
the Nationwide Subsidiaries is duly organized, validly existing and in good
standing under the Laws of the jurisdiction of its incorporation or formation
and has the requisite corporate power and authority to conduct its Business as
it is currently being conducted. Each of Nationwide and the Nationwide
Subsidiaries is duly qualified to do business, and is in good standing, in the
respective jurisdictions where the character of its Assets owned or leased or
the nature of its Business makes such qualification necessary, except where the
failure to be so qualified or in good standing would not, individually or in the
aggregate, be reasonably likely to have a Material Adverse Effect. Nationwide
possesses an Insurance License in Iowa and in





                                       30
<PAGE>   75



each jurisdiction in which Nationwide is required to possess an Insurance
License. All such Insurance Licenses, including, but not limited to,
authorizations to transact reinsurance, are in full force and effect without
amendment, limitation or restriction, and Nationwide does not have Knowledge of
any event, inquiry or Proceeding which is reasonably likely to lead to the
revocation, amendment, failure to renew, limitation, suspension or restriction
of any such Insurance License.

                  Section 5.2 AUTHORITY RELATIVE TO THIS AGREEMENT.

                           (a) Nationwide has the requisite power and authority
to execute and deliver this Agreement and, subject to approval of this Agreement
by the Members of Nationwide, to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly approved and authorized by the
Board of Directors of Nationwide. Except for the approval and adoption of this
Agreement by the Members of Nationwide, no other corporate proceedings on the
part of Nationwide are necessary to authorize this Agreement and the
transactions contemplated hereby. The affirmative vote of at least two-thirds of
the Members of Nationwide voting, in person or by properly executed proxy, at
the meeting called pursuant to Section 3.1 is the only vote of Members of
Nationwide necessary to approve and adopt this Agreement and the transactions
contemplated hereby.

                           (b) This Agreement has been duly and validly executed
and delivered by Nationwide and (assuming this Agreement is a valid and binding
obligation of Allied) constitutes a valid and binding agreement of Nationwide
enforceable against Nationwide in accordance with its terms, except that (i)
such enforcement may be subject to bankruptcy, insolvency, reorganization,
moratorium or other similar Laws now or hereafter in effect relating to
creditors' rights generally and (ii) the remedy of specific performance and
injunctive relief may be subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

                           (c) The Board of Directors of Nationwide has received
the opinion of Nationwide's financial advisor, Credit Suisse First Boston
Corporation, to the effect that the Merger is fair to the policyholders of
Nationwide, taken as a group, from a financial point of view. It is agreed and
understood that such opinion is for the benefit of Nationwide's Board of
Directors and may not be relied on by Allied or any Members or Affiliates
thereof.

                  Section 5.3 NO VIOLATION; GOVERNMENT FILINGS.

                           (a) The execution, delivery and performance of this
Agreement by Nationwide and the consummation by Nationwide of the transactions
contemplated hereby will not (i) constitute a breach or violation of or default
under the articles of incorporation or the by-laws (or similar organizational
documents) of Nationwide or any Nationwide Subsidiary, (ii) violate, conflict
with, or result in a breach of any provisions of, or constitute a default (or an





                                       31
<PAGE>   76



event which, with notice or lapse of time or both, would constitute a default)
under, or result in the termination of, or accelerate the performance required
by, or result in a right of termination or acceleration under, or result in the
creation of any Lien upon any of the Assets of Nationwide or any Nationwide
Subsidiary under, any of the terms, conditions or provisions of any Contract to
which Nationwide or any Nationwide Subsidiary is a party or to which it or any
of its Assets may be subject or (iii) constitute a breach or violation of or
default under any Environmental Permit, Law or License to which Nationwide or
any Nationwide Subsidiary is subject other than, in the case of clauses (ii) and
(iii), for any such breaches, violations, conflicts, terminations, defaults,
accelerations or Liens that are not, individually or in the aggregate,
reasonably likely to have a Material Adverse Effect.

                           (b) Except for (i) the approval of the Meeting Notice
by the Ohio Superintendent as contemplated by Section 3.1(b) hereof, (ii) the
approval of this Agreement by the Board of Nationwide as contemplated by Section
3.1(a) hereof, (iii) the filing of this Agreement with and the approval of such

Commissioner and the Iowa Attorney General under the Iowa Insurance Law and such
other applications, registrations, declarations, filings, authorizations,
Orders, consents and approvals as may be required under the Laws of other
jurisdictions, (iv) the filings required under the HSR Act and the expiration or
earlier termination of any waiting period applicable to the Merger under such
Act, (v) the filings pursuant to Section 2.3 hereof, (vi) the filing of
appropriate documents with and such consents as may be required under the
Investment Company Act and the Investment Advisers Act, (vii) such Consents and
Filings as may be required by any applicable state securities or "blue sky"
Laws, and (viii) such other such Consents or Filings the failure of which to
make or obtain would not, individually or in the aggregate, be reasonably likely
to prevent or be a material impediment to the consummation of the transactions
contemplated hereby or be reasonably likely to have a Material Adverse Effect.
No Consent or Filing of or with any Person is required with respect to
Nationwide or any Nationwide Subsidiary or any Nationwide Affiliate in
connection with the execution and delivery of this Agreement by Nationwide and
the consummation by Nationwide of the transactions contemplated hereby.

                                       32
<PAGE>   77



that differ from the Annual Statements or the Quarterly Statements described in
Section 5.4(a) or (b) hereto; and

                           (d) the audited SAP balance sheets of each Nationwide
Insurer as of December 31, 1995, 1996 and 1997 and the related audited summary

                  Each Nationwide SAP Statement complied (and, as to SAP
Statements filed after the date of this Agreement, will comply) in all material
respects with all applicable Laws when so filed, and all material deficiencies
with respect to any such Nationwide SAP Statement, of which Nationwide has

Business only in the ordinary course of business, consistent with past practice,
and there has not occurred (i) a Material Adverse Effect, or any event or events
which, individually or in the aggregate, are reasonably likely to have a
Material Adverse Effect; (ii) except as required by SAP, GAAP or applicable Law,
any material change by Nationwide in its accounting principles, practices or
methods; or (iii) except as required by SAP, GAAP or applicable Law, any

assumptions or principles of Nationwide.

required by SAP or GAAP to be set forth on a balance sheet of Nationwide or any
Nationwide Subsidiaries, other than Liabilities arising since the date of the

GAAP Financial Statements or the Nationwide SAP Statements, there are no
Proceedings pending or, to the Knowledge of Nationwide or any of the Nationwide

                           (a) To the Knowledge of Nationwide, neither
Nationwide nor any Nationwide Subsidiary is in violation (or, with notice or
lapse of time or both, would be in violation) of any term or provision of any
Law applicable to it or any of its Assets, the violation of which is,
individually or in the aggregate with all other such violations, reasonably
likely to have a Material Adverse Effect. Nationwide has made available to
Allied a list of all reports (including, but not limited to, draft reports) of
examinations of the affairs of each Nationwide Insurer (including, but not
limited to, market conduct examinations) issued by insurance regulatory
authorities for any period ending on a date on or after January 1, 1993; all
material deficiencies or violations in such reports for any prior period have
been resolved. All outstanding Insurance Contracts issued or assumed by any
Nationwide Insurer are, to the extent required by Law, on forms and at rates
approved by the insurance regulatory authorities of the jurisdictions where
issued or have been filed with and not objected to by such authorities within
the periods provided for objection.

                           (b) Neither Nationwide nor any Nationwide Subsidiary
is a party to any Contract with or other undertaking to, or is subject to any

<PAGE>   79



supervisory letter or other written communication of any kind from, any
Governmental Entity which (i) is reasonably likely to have a Material Adverse
Effect, or (ii) has been received since January 1, 1993 and relates to its

the Nationwide Subsidiaries been notified by any Governmental Entity that it is
contemplating issuing or requesting (or is considering the appropriateness of
issuing or requesting) any such Order, Contract, undertaking, letter or other
written communication.

                           (c) Nationwide has implemented procedures and
programs which are designed to provide reasonable assurance that Nationwide and
its agents and employees are in compliance in all material respects with all
applicable Laws, including, but not limited to, advertising, licensing and sales
Laws, except where noncompliance would not be reasonably likely to have a
Material Adverse Effect.

                  Section 5.10 INSURANCE ISSUED BY NATIONWIDE INSURERS.

                           (a) Since January 1, 1994, all claims and benefits
claimed by any Person under any Nationwide Insurance Contract have or will have
in all material respects been paid (or provision for payment thereof has been
made) in accordance with the terms of the Contracts under which they arose, and
such payments were not materially delinquent and were paid without fines or
penalties, except for any such claims or claim for benefits of less than
$500,000 for which the affected Nationwide Insurer reasonably believes there is
a reasonable basis to contest payment and is taking (or is preparing to take)
such action; and

                           (b) to the Knowledge of Nationwide, (i) each
insurance agent or broker, at the time such agent or broker wrote, sold or

broker (for the type of business written, sold or produced by such insurance
agent or broker) in the particular jurisdiction in which such agent or broker
wrote, sold or produced such business for Nationwide, and (ii) no such insurance
agent or broker violated (or with notice or lapse of time or both would have

the Business of Nationwide.

                           (a) Upon the terms and subject to the conditions
herein provided, each of the parties hereto agrees to use all reasonable efforts

                  Section 6.4 ACCESS AND INFORMATION.

                           (a) Subject to the terms of Section 6.4(b), each of
Nationwide and Allied shall (i) afford to the other and the Representatives of
the other, including environmental consultants, reasonable access during normal
business hours through the period commencing on the date hereof and continuing
until immediately prior to the Effective Time to all of its and its
Subsidiaries' Assets, books, Tax Returns, Contracts, commitments and records,
including for purposes of environmental assessments and other environmental due
diligence, and (ii) during such period, each of Nationwide and Allied shall
furnish promptly to the other all such information concerning its Business,

                           (b) Unless otherwise agreed in writing by the
parties, each of the parties agree (a) except as required by law, to keep all
Confidential Information confidential and not to disclose or reveal any
Confidential Information to any person other than those Persons employed by it
or on its behalf who are actively and directly participating in the planning,
negotiation and implementation of the transactions contemplated hereby or who
otherwise need to know the Confidential Information and to cause those persons
to observe the terms of this Section 6.4(b) and (b) not to use the Confidential
Information for any purpose other than in connection with the planning,
negotiation and implementation of the transactions contemplated hereby. In the
event of the termination of this Agreement for any reason, each of the parties
agrees to return, and cause its Representatives to return, to the other all
copies of written Confidential Information relating to the other and to destroy
all memoranda, notes and other writings prepared based upon or including
Confidential Information supplied by the other party and neither party shall use
Confidential Information supplied by the other for any purpose.

                  Section 6.5 NOTICE OF PROCEEDINGS. Each of Nationwide and
Allied shall promptly notify the other of, and provide to the other all
information relating to, any Proceedings or investigations commenced or, to the
best of its Knowledge, threatened which relate to the execution of this
agreement or the consummation of the transactions contemplated hereby.

                  Section 6.6 NOTIFICATION OF CERTAIN OTHER MATTERS. Each party
shall promptly notify the other of any of the following events should any such
events occur subsequent to the date hereof:

                           (a) the receipt by such party of any written notice
from any Person alleging that the consent of such Person is or may be required
in connection with the execution of this Agreement or the consummation of the
transactions contemplated hereby, and where the failure to obtain such a consent
is reasonably likely to have a Material Adverse Effect; and

                           (b) the receipt by such party of any written notice
from or to any Governmental Entity in connection with this Agreement or the
transactions contemplated hereby.





                                       42
<PAGE>   87




In furtherance of the foregoing, to the fullest extent permitted under
applicable Law, each party shall make available to the other with copies (or, to
the extent written materials are not involved, oral notice) of proposed notices,
applications or any other communications to any Governmental Entity or rating
agency in connection with this Agreement or the transactions contemplated
hereby, including, but not limited to, in respect of the Governmental Approvals,
in each case at least three (3) Business Days prior to dispatch of written
materials (or, to the extent written materials are not involved, prior to
initiation) and neither Nationwide nor Allied will dispatch (or, to the extent
written materials are not involved, initiate) such notice, application or
communication without the prior consent of the other party, which consent shall
not be unreasonably withheld or delayed.

                  Section 6.7 INDEMNIFICATION.

                           (a) Nationwide agrees that all rights to
indemnification now existing in favor of any of the current or former employees,
directors, agents or officers of Allied or any of the Allied Subsidiaries (the
"Indemnitees"), with respect to any Losses (including, but not limited to,
Losses arising out of any litigation or threatened litigation) based on,
arising, in whole or in part, out of, or otherwise in respect of, any action
which is taken, or matter existing or occurring on or prior to the Effective
Time, as provided in Allied's articles of incorporation or by-laws or any
indemnification agreements by and between any of the Indemnitees and Allied or
otherwise existing to the fullest extent under Law on the date hereof shall
survive the Merger.

                           (b) From and after the Effective Time, Nationwide
agrees that it will indemnify and hold harmless each of the Indemnitees from and
against any and all Losses (including, but not limited to, Losses arising out of
any litigation or threatened litigation) based on, arising, in whole or in part,
out of, or otherwise in respect of, any action which is taken, or matter
existing or occurring on or prior to the Effective Time. Nothing contained
herein, however, shall require Nationwide to indemnify any Indemnitee if a court
of competent jurisdiction shall have determined that such indemnification is
unenforceable or void as a matter of public policy, and such determination shall
have become final and nonappealable.

                           (c) For a period of six years after the Effective
Time, Nationwide shall maintain in effect directors' and officers' liability
insurance covering those persons who are currently covered by Allied's
directors' and officers' liability insurance policy on terms (including the
amounts of coverage and the amounts of deductibles, if any) that are comparable
to the terms now applicable to directors and officers of Nationwide, or, if more
favorable to Allied's directors and officers, the terms now applicable to them
under Allied's current policies; provided, however, that in no event shall
Nationwide be required to expend in excess of the greater of 200% of the annual
premium currently paid by Allied for such coverage and the annual premium paid
by Nationwide for its current directors' and officers' liability insurance
coverage (the "Maximum Premium"); and provided further, that if the premium for
such coverage exceeds the Maximum Premium, Nationwide shall purchase a policy
with the greatest coverage available for





                                       43
<PAGE>   88



the Maximum Premium.

                           (d) In the event that Nationwide or any of its
successors or assigns (i) consolidates with or merges into any other Person and
is not the continuing or surviving corporation or entity of such consolidation
or merger or (ii) transfers or conveys all or substantially all of its
properties and assets to any Person, then, and in each such case, proper
provision shall be made so that the successors and assigns of Nationwide assume
the obligations set forth in this Section 6.7.

                           (e) The provisions of this Section 6.7 shall survive
the consummation of the Merger at the Effective Time and are intended to be for
the benefit of, and shall be enforceable by, each Indemnitee, his or her heirs
and his or her representatives and are in addition to, and not in substitution
for, any other rights to indemnification or contribution that any such Person
may have under the articles of incorporation or by-laws of the Surviving Company
or any of its Subsidiaries, under any contract, under applicable Law or
otherwise.

                  Section 6.8 TRANSFER TAXES. The Surviving Company shall pay or
cause to be paid any real property transfer and similar Taxes to which the
Allied policyholders may be subject as a result of the Merger and the
transactions contemplated hereby, and the Surviving Company shall file or cause
to be filed all Tax Returns relating to such transfer Taxes which are due.

                  Section 6.9 ACQUISITION PROPOSALS. Allied will not, and will
not permit or cause any of its Subsidiaries or any of the officers or directors
of it or its Subsidiaries to, and shall direct its and its Subsidiaries'
Representatives not to, directly or indirectly, initiate, solicit, knowingly
encourage or otherwise knowingly facilitate the making of any Acquisition
Proposal. Allied will not, and will not permit or cause any of its Subsidiaries
or any of the officers and directors of it or its Subsidiaries to and shall
direct its and its Subsidiaries' employees, agents and Representatives not to,
directly or indirectly, engage in any negotiations concerning, or provide any
confidential information or data to, or have any discussions with, any Person
relating to an Acquisition Proposal, whether made before or after the date of
this Agreement, or otherwise knowingly facilitate any effort or attempt to make
or implement an Acquisition Proposal; provided, however, that nothing contained
in this Agreement shall prevent Allied or its Board of Directors from (A)
providing information in response to a request therefor by a Person who has made
an unsolicited bona fide written Acquisition Proposal; (B) engaging in any
negotiations or discussions with any Person who has made an unsolicited bona
fide written Acquisition Proposal; or (C) recommending such an Acquisition
Proposal to the Members of Allied, if and only to the extent that, (i) in each
such case referred to in clause (A), (B) or (C) above, the Board of Directors of
Allied determines in good faith that the failure to take such action is
reasonably likely to result in a breach of such Board's fiduciary duties under,
or otherwise violate, applicable Law; and (ii) in each case referred to in
clause (B) or (C) above, the Board of Directors of Allied determines in good
faith that such Acquisition Proposal may be a Superior Proposal. Allied will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations





                                       44
<PAGE>   89



with any parties conducted heretofore with respect to any of the foregoing.
Allied agrees that it will take the necessary steps to promptly inform the
individuals or entities referred to in the first sentence hereof of the
obligations undertaken in this Section 6.9.

                  Section 6.10 LITIGATION. From and after the date hereof and
until the Effective Time, Nationwide shall cease, in any and all respects, the
prosecution of any pending litigation against Allied or any Affiliates thereof.
Immediately following the Effective Time, Nationwide shall dismiss, with
prejudice, any and all litigation brought by Nationwide against Allied or any
Affiliates thereof.

                  Section 6.11 HSR ACT. Nationwide and Allied shall take all
actions necessary to file as soon as practicable after the date hereof all
notifications, filings and other documents required under the HSR Act, and to
respond as promptly as practicable to any inquiries received from the FTC, the
Antitrust Division and any other Governmental Entity for additional information
or documentation and to respond as promptly as practicable to all inquiries and
requests received from any State Attorney General or other Governmental Entity
in connection therewith.

                  Section 6.12 TAX TREATMENT. The parties intend the Merger to
qualify as a reorganization under Section 368(a) of the Code; each party and
its affiliates shall use its best efforts to cause the Merger to so qualify.
Each of the parties agrees that neither it nor any of its Affiliates shall take
any action, including any transfer or other disposition of assets or any
interest in Allied after the Closing, that would cause the Merger not to qualify
as a reorganization under Section 368(a) of the Code. Nationwide shall report
the Merger for income tax purposes as a reorganization within the meaning of
Section 368(a) of the Code and any comparable state or local tax statute.

Time (other than those Governmental Approvals for which the failure to obtain
would not be reasonably likely to have a Material Adverse Effect) shall have
been obtained and not rescinded or adversely modified or limited or, if merely
required to be filed, such filings shall have been made and accepted, and all
waiting periods prescribed by applicable Law shall have expired or been
terminated in accordance with applicable Law; provided that no such Governmental
Approval or other Consent or Filing shall contain any conditions or limitations
that impose or seek to impose any limitation on the ability of the Surviving
Company and its Subsidiaries, taken as a whole, to conduct its Business or own
its Assets after the Effective Time in substantially the same manner as the
parties and their respective Subsidiaries presently conduct their Business or
own their Assets and which conditions and limitations would have a Material
Adverse Effect on the Surviving Company and its Subsidiaries, taken as a whole;
and

                           (c) no Order entered or Law promulgated or enacted by
any Governmental Entity shall be in effect which would prevent the consummation
of the Merger or any other material transactions completed hereby, and no
Proceeding brought by a Governmental Entity shall have been commenced and be

restructure the Merger or any other material transactions contemplated hereby.

MERGER. The obligations of Allied to effect the Merger shall be subject to the
fulfillment at or prior to the Closing Date of the following conditions, any one

contained in this Agreement shall be true and correct on the date hereof and on
and as of the Closing Date as though made on the Closing Date (other than those
representations and warranties that expressly address matters only as of a
particular date or only with respect to a specific period of time which need
only be true and correct as of such date or with respect to such period), except
where the failure of such representations and warranties to be so true and
correct (without giving effect to any limitation as to "materiality" or
"material adverse effect" set forth therein), does not have, and is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Nationwide; and

                           (b) Nationwide shall have performed and complied in
all material respects with all obligations, covenants and agreements required to
be performed and complied with by it under this Agreement at or prior to Closing

                           (a) The representations and warranties of Allied
contained in this Agreement shall be true and correct on the date hereof and on
and as of the Closing Date as though made on the Closing Date (other than those
representations and warranties that expressly address matters only as of a
particular date or only with respect to a specific period of time which need
only be true and correct as of such date or with respect to such period), except
where the failure of such representations and warranties to be so true and
correct (without giving effect to any limitation as to "materiality" or
"material adverse effect" set forth therein), does not have, and is not
reasonably likely to have, individually or in the aggregate, a Material Adverse
Effect on Allied; and

                           (b) Allied shall have performed and complied in all
material respects with all obligations, covenants and agreements required to be
performed and complied with by it under this Agreement at or prior to the
Closing Date.

                  Section 7.4 FRUSTRATION OF CLOSING CONDITIONS. Neither Allied
nor Nationwide may rely on the failure of any condition set forth in Section
7.1, 7.2 or 7.3, as the case may be, to be satisfied if such failure was caused
by such party's failure to use its best efforts to consummate the Merger and the
other transactions contemplated by this Agreement.

                                  ARTICLE VIII

                                   TERMINATION

any adjournment thereof duly held for such purpose; or

                           (d) by Allied if the number of votes in favor of this

PROVIDED, HOWEVER, that if any such breach is curable by Nationwide through the
exercise of its best efforts and for so long as Nationwide shall be so using its
best efforts to cure such breach, Allied may not terminate this Agreement
pursuant to this Section 8.1(e); or

                           (f) by Nationwide if Allied (x) breaches or fails in
any material respect to perform or comply with any of its material covenants and
agreements contained herein or (y) breaches its representations and warranties
in any material respect and such breach would have, or is reasonably likely to
have, a Material Adverse Effect on Allied, in each case such that the conditions
set forth in Section 7.1 or Section 7.3 would not be satisfied; PROVIDED,
HOWEVER, that if any such breach is curable by Allied through the exercise of
its best efforts and for so long as Allied shall be so using its best efforts to
cure such breach, Nationwide may not terminate this Agreement pursuant to this
Section 8.1(f); or

                           (g) by Allied, if the Board of Directors of Allied
(or any committee thereof) shall have withdrawn or modified or changed in a
manner adverse to Nationwide its approval or recommendation of this Agreement
or the Merger in order to approve and permit Allied to execute a definitive
agreement with a Third Party relating to an Superior Proposal; or

Nationwide or Allied, as provided in Section 8.1, written notice thereof shall
forthwith be given to the other party specifying the provision hereof pursuant
to which such termination is made, this Agreement shall thereafter become void
and there shall be no Liability on the part of either party hereto against the
other party hereto, or on the part of its directors, officers, employees,
policyholders, shareholders or agents (or those of any of its Subsidiaries or
Affiliates), except that (i) any such termination shall be without prejudice to
the rights of either party hereto (or any of its Subsidiaries or Affiliates)
arising out of the willful breach by the other party of any covenant or
agreement contained in this Agreement, and (ii) with respect to Nationwide and
Allied, the obligations pursuant to this Section 8.2, Section 6.4(b) and
Section 9.2 shall survive termination.

of a party to any such extension or waiver shall be valid only if set forth in

covenant, obligation, condition or agreement by the party entitled to the
benefit thereof.

                  Section 9.6 PUBLICITY. So long as this Agreement is in effect,

Governmental Entity, (B)prohibit either party hereto (or its Affiliates) from

or remedies of any nature under or by reason of this Agreement, except as
expressly provided in Section 2.6, Section 2.7, Section 6.7, Section 6.8,
Section 6.10 and Section 6.12 hereof.

                  Section 9.10 DUPLICATES; COUNTERPARTS. This Agreement shall be
executed in duplicate and may be executed in counterparts, each of which shall
be deemed to constitute an original and constitute one and the same instrument.

produce or account for more than one such counterpart signed by the party
against whom enforcement is sought.

                  Section 9.11 GOVERNING LAW; JURISDICTION. This Agreement shall

result of future legislative action, such holding or action shall be strictly
construed and shall not affect the validity or effect of the remaining terms and
provisions hereof or the validity or enforceability of the offending term or
provision in any other situation or in any other jurisdiction. If the final
judgment of a court of competent jurisdiction or other authority declares that
any term or provision hereof is invalid, void or unenforceable, the parties
agree that the court making such determination shall have the





                                       52
<PAGE>   97



power to reduce the scope, duration, area or applicability of the term or
provision, to delete specific words or phrases, or to replace any invalid, void
or unenforceable term or provision with a term or provision that is valid and
enforceable and that comes closest to expressing the intention of the invalid or
unenforceable term or provision; PROVIDED, HOWEVER, that the parties shall use
reasonable efforts, including, but not limited to, the amendment of this
Agreement, to ensure that this Agreement shall reflect as closely as practicable
the intent of the parties hereto.

                  Section 9.14 SPECIFIC PERFORMANCE. Each of the parties hereto

or injunctions to prevent breaches of the provisions of this Agreement and to

consents to the service of process in any action or proceeding by mailing copies
thereof by registered United States mail, postage prepaid, return receipt
requested, to its address as specified in or pursuant to Section 9.3 hereof.
However, the foregoing shall not limit the right of a party to effect service of
process on the other party by any other legally available method.

                  Section 9.18 INTERPRETATION.

                           (a) When a reference is made in this Agreement to a

         Nationwide is one insurance company in a large group of affiliated
insurance companies called the Nationwide Insurance Enterprise (the
"Enterprise"). Nationwide agrees that for as long as your policy remains
continuously in force (including renewals or replacements thereof) from and
after the Effective Time with an insurance company within the Enterprise that is
authorized to transact property and casualty insurance or reinsurance business:

         A. Your policy shall have those voting rights within Nationwide as if
it were a policy issued by Nationwide, as and to the extent provided under the
Ohio Insurance Law and Nationwide's Articles of Incorporation;

         B. Your policy shall have those rights in the event of the liquidation,
merger, consolidation, mutual holding company reorganization, demutualization or
similar extraordinary transaction of Nationwide as if your policy had been
continuously with Nationwide since the date of its initial issuance by Allied.
Such rights shall not be reduced by reason of any policyholder dividend paid in
respect of your policy in connection with the Merger.

         This Certificate shall continue in effect as long as your policy has
been renewed or replaced, without a lapse in coverage, by any insurance company
within the Enterprise that is authorized to transact property and casualty
insurance or reinsurance business. This Certificate, as of the Effective Time,
forms a part of and should be attached to your policy.

                              SHAREHOLDER AGREEMENT

                  SHAREHOLDER AGREEMENT, dated as of June 3, 1998, between

an Ohio corporation and wholly-owned subsidiary of Nationwide ("Sub"), and
Allied Life Financial Corporation, an Iowa corporation (the "Company"), propose
to enter into an Agreement and Plan of Merger, dated the date hereof (as the
same may be amended or supplemented, the "Merger Agreement"), which provides for
a cash tender offer by Sub (as such tender offer may hereafter be amended from
time to time, the "Offer") to purchase all shares of common stock, no par value,
of the Company (the "Common Shares") and, following the consummation of the
Offer, the merger of Sub with the Company (the "Merger");

                  WHEREAS, the Securityholder is the record and beneficial owner
of the number of (i) Common Shares, and (ii) shares of 6.75% Series Preferred
Stock, no par value, of the Company and (collectively, the "Preferred Shares")
set forth on Schedule A hereto; such securities, as they may be adjusted by
stock dividend, stock split, recapitalization, combination or exchange of
shares, merger, consolidation, reorganization or other change or transaction of
or by the Company, together with securities that may be acquired after the date
hereof by the Securityholder, including Common Shares issuable upon the exercise
of options to purchase Common Shares (as the same may be adjusted as aforesaid),
being collectively referred to herein as the "Securities"; and

                  WHEREAS, as a condition to their willingness to enter into the
Merger Agreement, Nationwide has requested that the Securityholder enter into
this Agreement (capitalized terms not otherwise defined herein shall have the
meanings set forth in the Merger Agreement);

                  NOW, THEREFORE, to induce Nationwide to enter into, and in
consideration of it entering into, the Merger Agreement, and in consideration of
the premises and the representations, warranties and agreements contained
herein, the parties hereto, intending to be legally bound hereby, agree as

<PAGE>   103
                  1. Covenants of the Securityholder. The Securityholder agrees
as follows:

                  (a) The Securityholder shall not, except as contemplated by
the terms of this Agreement, (i) sell, transfer, pledge, assign or otherwise
dispose of, or enter into any Contract (as defined below), option or other
arrangement (including any profit sharing arrangement) or understanding with
respect to the sale, transfer, pledge, assignment or other disposition of, the
Securities to any person, or (ii) enter into any voting arrangement, whether by
proxy, voting agreement, voting trust, power-of-attorney or otherwise, with
respect to the Securities.

                  (b) The Securityholder shall not, nor shall the Securityholder
permit any investment banker, financial adviser, attorney, accountant or other

proposal which constitutes, or may reasonably be expected to lead to, any
Acquisition Proposal or (ii) participate in any discussions or negotiations
regarding any Acquisition Proposal.

                  (c) At any meeting of shareholders of the Company called to
vote upon the Merger and the Merger Agreement or at any adjournment thereof or
in any other circumstances upon which a vote, consent or other approval
(including by written consent) with respect to the Merger and the Merger
Agreement is sought, the Securityholder shall, including by initiating a written
consent solicitation if requested by Nationwide, vote (or cause to be voted)
such Securityholder's Securities in favor of the Merger, the adoption of the
Merger Agreement and the approval of the other transactions contemplated by the
Merger Agreement. At any meeting of shareholders of the Company or at any
adjournment thereof or in any other circumstances upon which the
Securityholder's vote, consent or other approval is sought, the Securityholder
shall vote (or cause to be voted) the Securityholder's Securities against (i)
any merger (other than the Merger), consolidation, combination, sale of

other proposal or transaction would in any manner impede, frustrate, prevent or
nullify, the Merger, the Merger Agreement or any of the other transactions
contemplated by the Merger Agreement including any consent to

                  2. Grant of Irrevocable Proxy Coupled with an Interest;
Appointment of Proxy.

                  (a) Subject to governmental approvals, the Securityholder
hereby irrevocably grants to, and appoints, any individual who shall be
designated by Nationwide as the Securityholder's proxy and attorney-in-fact
(with full power of substitution), for and in the name, place and stead of the
Securityholder, to vote the Securityholder's Securities, or grant a consent or
approval in respect of such Securities, at any meeting of shareholders of the
Company or at any adjournment thereof or in any other circumstances upon which
their vote, consent or other approval is sought, (i) in favor of the Merger, the
adoption by the Company of the Merger Agreement and the approval of the other
transactions contemplated by the Merger Agreement, and (ii) against any
Alternative Transaction or Frustrating Transaction.

                  (b) The Securityholder represents that any proxies heretofore
given in respect of the Securityholder's Securities are not irrevocable, and
that any such proxies are hereby revoked.

                  (c) THE SECURITYHOLDER HEREBY AFFIRMS THAT THE PROXY SET FORTH
IN THIS SECTION 2 IS COUPLED WITH AN INTEREST AND IS IRREVOCABLE UNTIL SUCH TIME
AS THIS AGREEMENT TERMINATES IN ACCORDANCE WITH ITS TERMS. The Securityholder
hereby further affirms that the irrevocable proxy is given in connection with
the execution of the Merger Agreement, and that such irrevocable proxy is given
to secure the performance of the duties of the Securityholder under this
Agreement. The Securityholder hereby ratifies and confirms all that such
irrevocable proxy may lawfully do or cause to be done by virtue hereof.

                  3. Acquisition Proposals.

                  Notwithstanding anything to the contrary contained in this
Agreement, during any period of time that the Securityholder is not prohibited
by the Agreement and Plan of Merger, dated as of the date hereof, by and between
Securityholder and Nationwide (the "Allied Mutual Merger Agreement") from (A)
providing information in response to a request therefor by a Person who has made
an unsolicited bona fide written Acquisition Proposal; (B) engaging in any
negotiations or discussions with any Person who has made an unsolicited bona

<PAGE>   105

holders of the Securityholder, the Securityholder's obligations under Sections 1

Allied Mutual Merger Agreement.

                  4. Representations and Warranties of the Securityholder. The
Securityholder hereby represents and warrants to Nationwide as follows:

                  (a) Authority. The Securityholder has all requisite corporate
power and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution, delivery and performance of
this Agreement and the consummation of the transactions contemplated hereby have
been duly authorized by the Securityholder. This Agreement has been duly
executed and delivered by the Securityholder and, assuming this Agreement
constitutes a valid and binding obligation of Nationwide, constitutes a valid
and binding obligation of the Securityholder enforceable against the
Securityholder in accordance with its terms, except that (i) such enforcement
may be subject to bankruptcy, insolvency, reorganization, moratorium or other
similar laws now or hereafter in effect relating to creditors' rights generally
and (ii) the remedy of specific performance and injunctive relief may be subject
to equitable defenses and to the discretion of the court before which any
proceeding therefor may be brought. Except for the informational filings with
the Securities and Exchange Commission and except for any state insurance
department approvals or filings, neither the execution, delivery or performance
of this Agreement by the Securityholder nor the consummation by the
Securityholder of the transactions contemplated hereby will (i) require any
filing with, or permit, authorization, consent or approval (collectively,
"Governmental Approvals") of, any federal, state, local or municipal foreign or
other government or subdivision, branch, department or agency thereof or any
governmental or quasi-governmental authority of any nature, including any court
or other tribunal, (a "Governmental Entity"), except where the failure to obtain
any such Governmental Approvals would not be reasonably likely to adversely
affect the transactions contemplated hereby, (ii) result in a violation or
breach of, or constitute (with or without due notice or lapse of time or both) a
default under, or give rise to any right of termination, amendment, cancellation
or acceleration under, or result in the creation of any lien upon any of the
properties or assets of the Securityholder under, any of the terms, conditions
or provisions of any note, bond, mortgage, indenture, lease, license, permit,
concession, franchise, contract, agreement or other instrument or obligation (a
"Contract") to which the Securityholder is a party or by which the
Securityholder or any of the

                                        4
<PAGE>   106
Securityholder's properties or assets, including the Securityholder's
Securities, may be bound, except for such violations, breaches, defaults, rights
of termination, amendment, cancellation and acceleration and liens which would
not be reasonably likely to adversely affect the transactions contemplated
hereby or (iii) violate any judgment, order, writ, preliminary or permanent
injunction or decree (an "Order") or any statute, law, ordinance, rule or
regulation of any Governmental Entity (a "Law") applicable to the Securityholder
or any of the Securityholder's properties or assets, including the
Securityholder's Securities, except for such violations which would not be
reasonably likely to adversely affect the transactions contemplated hereby

                  (b) The Securities. The Securityholder's Securities and the
certificates representing such Securities are now, and at all times during the
term hereof will be, held by such Securityholder, or by a nominee or custodian
for the benefit of such Securityholder, and the Securityholder has good and
marketable title to such Securities, free and-clear of any liens, proxies,
voting trusts or agreements, understandings or arrangements, except for any such
liens or proxies arising hereunder and the agreements made hereby. The
Securityholder owns of record or beneficially no securities of the Company, or
any options, warrants or rights exercisable for securities of the Company, other
than such Securityholder's Securities, as set forth on Schedule A hereto.

                  (c) Brokers. Except as provided in the Allied Mutual Merger
Agreement, no broker, investment banker, financial advisor or other person is
entitled to any broker's, finder's, financial advisor's or other similar fee or
commission in connection with the transactions contemplated by this Agreement
based upon arrangements made by or on behalf of the Securityholder.

                  (d) Merger Agreement. The Securityholder understands and
acknowledges that Nationwide is entering into the Merger Agreement in reliance
upon the Securityholder's execution and delivery of this Agreement.

                  5. Representations and Warranties of Nationwide. Nationwide
hereby represents and warrants to the Securityholder as follows:

                  (a) Authority. Nationwide has the requisite corporate power
and authority to execute and deliver this Agreement and to consummate the
transactions contemplated hereby. The execution, delivery and performance of
this Agreement by Nationwide and the consummation of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Nationwide.

                                        5
<PAGE>   107
This Agreement has been duly executed and delivered by Nationwide and, assuming
this Agreement constitutes a valid and binding obligation of the Securityholder,
constitutes a valid and binding obligation of Nationwide enforceable in
accordance with its terms, except that (i) such enforcement may be subject to
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereafter in effect relating to creditors' rights generally and (ii) the remedy
of specific performance and injunctive relief may be subject to equitable
defenses and to the discretion of the court before which any proceeding therefor
may be brought.

                  (b) Securities Act. The Securities will be acquired in
compliance with, and Nationwide will not offer to sell or otherwise dispose of
any Securities so acquired by it in violation of any of, the Securities Exchange
Act of 1934, as amended, or the registration requirements of the Securities Act
of 1933, as amended.

                  6. Further Assurances. Except as otherwise provided in Section
3, the Securityholder will, from time to time, execute and deliver, or cause to
be executed and delivered, such additional or further transfers, assignments,
endorsements, consents and other instruments as Nationwide may reasonably
request for the purpose of effectively carrying out the transactions
contemplated by this Agreement and to vest the power to vote the
Securityholder's Securities as contemplated by Section 2. Nationwide agrees to
use its best efforts to take, or cause to be taken, all actions necessary to
comply promptly with all legal requirements that may be imposed with respect to
the transactions contemplated by this Agreement.

                  7. Termination. This Agreement, and all rights and obligations
of the parties hereunder, shall terminate on the earlier of (x) the termination
of the Merger Agreement (except pursuant to Section 8.1(d) of the Merger
Agreement in which case this Agreement shall continue in effect) of in
accordance with its terms and (y) the termination of the Allied Mutual Merger
Agreement. Nothing in this Section 7 shall relieve any party from liability for
willful breach of this Agreement.

                  8. General Provisions.

                  (a) Assignment; Binding Effect. Neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned by any of

                                     PART A

     490.1301     DEFINITIONS FOR DIVISION XIII. In this division:

     1.   "Beneficial shareholder" means the person who is a beneficial owner of
shares held by a nominee as the record shareholder.

     2.   "Corporation" means the issuer of the shares held by a dissenter
before the corporate action, or the surviving or acquiring corporation by merger
or share exchange of that issuer.

     3.   "Dissenter" means a shareholder who is entitled to dissent from
corporate action under section 490.1302 and who exercises that right when and in
the manner required by sections 490.1320 through 490.1328.

     4.   "Fair value," with respect to a dissenter's shares, means the value of
the shares immediately before the effectuation of the corporate action to which
the dissenter objects, excluding any appreciation or depreciation in
anticipation of the corporate action unless exclusion would be inequitable.

     5.   "Interest" means interest from the effective date of the corporate
action until the date of payment, at the average rate currently paid by the
corporation on its principal bank loans or, if none, at a rate that is fair and
equitable under all the circumstances.

     6.   "Record shareholder" means the person in whose name shares are
registered in the records of a corporation or the beneficial owner of shares to
the extent of the rights granted by a nominee certificate on file with a
corporation.

     7.   "Shareholder" means the record shareholder or the beneficial
shareholder.


     490.1302     SHAREHOLDERS' RIGHT TO DISSENT.

     1.   A shareholder is entitled to dissent from, and obtain payment of the
fair value of the shareholder's shares in the event of, any of the following
corporate actions:

          a.   Consummation of a plan of merger to which the corporation is a
     party if either of the following apply;

               (1)   Shareholder approval is required for the merger by section
          490.1103 or the articles of incorporation and the shareholder is
          entitled to vote on the merger.




<PAGE>   117
               (2)   the corporation is a subsidiary that is merged with its
          parent under section 490.1104.

          b.   Consummation of a plan of share exchange to which the corporation
     is a party as the corporation whose shares will be acquired, if the
     shareholder is entitled to vote on the plan.

          c.   Consummation of a sale or exchange of all, or substantially all,
     of the property of the corporation other than in the usual and regular
     course of business, if the shareholder is entitled to vote on the sale or
     exchange, including a sale in dissolution, but not including a sale
     pursuant to court order or a sale for cash pursuant to a plan by which all
     or substantially all of the net proceeds of the sale will be distributed to
     the shareholders within one year after the date of sale.

          d.   An amendment of the articles of incorporation that materially and
     adversely affects rights in respect of a dissenter's shares because it does

          redemption or repurchase, of the shares.

               (3)   Alters or abolishes a preemptive right of the holder of the
          shares to acquire shares or other securities.

               (4)   Excludes or limits the right of the shares to vote on any
          matter, or to cumulate votes, other than a limitation by dilution
          through issuance of shares or other securities with similar voting
          rights.

               (5)   Reduces the number of shares owned by the shareholder to a
          fraction of a share if the fractional share so created is to be
          acquired for cash under section 490.604.

               (6)   Extends, for the first time after being governed by this
          chapter, the period of duration of a corporation organized under
          chapter 491 or 496A and existing for a period of years on the day
          preceding the date the corporation is first governed by this chapter.

          e.   Any corporate action taken pursuant to a shareholder vote to the
     extent the articles of incorporation, bylaws, or a resolution of the board
     of directors provides that voting or nonvoting shareholders are entitled to
     dissent and obtain payment for their shares.

     2.   A shareholder entitled to dissent and obtain payment for the
shareholder's shares under this chapter is not entitled to challenge the
corporate action creating the shareholder's entitlement unless the action is
unlawful or fraudulent with respect to the shareholder or the corporation.

    490.1303     DISSENT BY NOMINEES AND BENEFICIAL OWNERS.

     1.   A record shareholder may assert dissenters' rights as to fewer than
all the shares registered in that shareholder's name only if the shareholder
dissents with respect to all shares beneficially owned by

                                     
 
<PAGE>   118
any one person and notifies the corporation in writing of the name and address 
of each person on whose behalf the shareholder asserts dissenters' rights. The 
rights of a partial dissenter under this subsection are determined as if the 
shares as to which the shareholder dissents and the shareholder's other shares 
were registered in the names of different shareholders.

     2.   A beneficial shareholder may assert dissenters' rights as to shares
held on the shareholder's behalf only if the shareholder does both of the
following:

          a.   Submits to the corporation the record shareholder's written
     consent to the dissent not later than the time the beneficial shareholder
     asserts dissenters' rights.

          b.   Does so with respect to all shares of which the shareholder is
     the beneficial shareholder or over which that beneficial shareholder has
     power to direct the vote.


                                     PART B

     490.1320     NOTICE OF DISSENTERS' RIGHTS.

must state that shareholders are or may be entitled to assert dissenters' rights
under this part and be accompanied by a copy of this part.

     2.   If corporate action creating dissenters' rights under section 490.1302
is taken without a vote of shareholders, the corporation shall notify in writing
all shareholders entitled to assert dissenters' rights that the action was taken
and send them the dissenters' notice described in section 490.1322.

     490.1321     NOTICE OF INTENT TO DEMAND PAYMENT.

          a.   Deliver to the corporation before the vote is taken written
     notice of the shareholder's intent to demand payment for the shareholder's
     shares if the proposed action is effectuated.

          b.   Not vote the dissenting shareholder's shares in favor of the
     proposed action.

     2.   A shareholder who does not satisfy the requirements of subsection 1 is
not entitled to payment for the shareholder's shares under this part.

     490.1322     DISSENTERS' NOTICE.

     1.   If proposed corporate action creating dissenters' rights under section
490.1302 is authorized at a shareholders' meeting, the corporation shall deliver
a written dissenters' notice to all shareholders who satisfied the requirements
of section 490.1321.

<PAGE>   119



     2.   The dissenters' notice must be sent no later than ten days after the

corporate action is taken without a vote of the shareholders, no later than ten
days after the corporate action is taken, and must do all of the following:

     certificates for certificated shares must be deposited.

          b.  Inform holders of uncertificated shares to what extent transfer of

          c.   Supply a form for demanding payment that includes the date of the
     first announcement to news media or to shareholders of the terms of the
     proposed corporate action and requires that the person asserting
     dissenters' rights certify whether or not the person acquired beneficial
     ownership of the shares before that date.

          d.   Set a date by which the corporation must receive the payment
     demand, which date shall not be fewer than thirty nor more than sixty days
     after the date the dissenters' notice is delivered.

          e.   Be accompanied by a copy of this division. (Last amended by Ch.

and deposit the shareholder's certificates in accordance with the terms of the

     2.   The shareholder who demands payment and deposits the shareholder's

division.

     490.1324     SHARE RESTRICTIONS.

     1.   The corporation may restrict the transfer of uncertificated shares

corporate action is taken or the restrictions released under section 490.1326.


     2.   The person for whom dissenters' rights are asserted as to
uncertificated shares retains all other rights of a shareholder until these
rights are canceled or modified by the taking of the proposed corporate action.










<PAGE>   120
     490.1325     PAYMENT.

     1.   Except as provided in section 490.1327, at the time the proposed
corporate action is taken, or upon receipt of a payment demand, whichever occurs
later, the corporation shall pay each dissenter who complied with section
490.1323 the amount the corporation estimates to be the fair value of the
dissenter's shares, plus accrued interest.

     2.   The payment must be accompanied by all of the following:

          a.   The corporation's balance sheet as of the end of a fiscal year
     ending not more than sixteen months before the date of payment, an income
     statement for that year, a statement of changes in shareholders' equity for
     that year and the latest available interim financial statements, if any.

          b.   A statement of the corporation's estimate of the fair value of
     the shares.

          c.   An explanation of how the interest was calculated.

          d.   A statement of the dissenter's right to demand payment under

          e.   A copy of this division. (Last amended by Ch. 211, L. '91, eff.
     7-1-91.)

     490.1326     FAILURE TO TAKE ACTION.

     1.   If the corporation does not take the proposed action within one
hundred eighty days after the date set for demanding payment and depositing
share certificates, the corporation shall return the deposited certificates and
release the transfer restrictions imposed on uncertified shares.

     2.   If after returning deposited certificates and releasing transfer
restrictions, the corporation takes the proposed action, it must send a new
dissenters' notice under section 490.1322 as if the corporate action was taken
without a vote of the shareholders and repeat the payment demand procedure.
(Last amended by Ch. 171, L. '91, eff. 7-1-91.)

     490.1327     AFTER-ACQUIRED SHARES.

     1.   A corporation may elect to withhold payment required by section
490.1325 from a dissenter unless the dissenter was the beneficial owner of the
shares before the date set forth in the dissenters' notice as the date of the
first announcement to news media or to shareholders of the terms of the proposed
corporate action.

     2.   To the extent the corporation elects to withhold payment under
subsection 1, after taking the proposed corporate action, it shall estimate the
fair value of the shares, plus accrued interest, and shall pay this amount to
each dissenter who agrees to accept it in full satisfaction of the dissenter's
demand. The corporation shall send with its offer a statement of its estimate of
the fair value of the shares, an explanation of how the interest was calculated
and a statement of the dissenter's right to demand payment under section
490.1328.

<PAGE>   121
     490.1328     PROCEDURE IF SHAREHOLDER DISSATISFIED WITH PAYMENT OR OFFER.

     1.   A dissenter may notify the corporation in writing of the dissenter's
own estimate of the fair value of the dissenter's shares and amount of interest
due and demand payment of the dissenter's estimate, less any payment under
section 490.1325, or reject the corporation's offer under section 490.1327 and
demand payment of the fair value of the dissenter's shares and interest due, if
any of the following apply:

          a.   The dissenter believes that the amount paid under section
     490.1325 or offered under section 490.1327 is less than the fair value of
     the dissenter's shares or that the interest due is incorrectly calculated.

          b.   The corporation fails to make payment under section 490.1325
     within sixty days after the date set for demanding payment.

          c.   The corporation, having failed to take the proposed action, does
     not return the deposited certificates or release the transfer restrictions
     imposed on uncertified shares within sixty days after the date set for
     demanding payment. 

     2.   A dissenter waives the dissenter's right to demand payment under this
section unless the dissenter notifies the corporation of the dissenter's demand
in writing under subsection 1 within thirty days after the corporation made or
offered payment for the dissenter's shares.

                                     PART C

     490.1330     COURT ACTION.

     1.   If a demand for payment under section 490.1328 remains unsettled, the
corporation shall commence a proceeding within sixty days after receiving the
payment demand and petition the court to determine the fair value of the shares
and accrued interest. If the corporation does not commence the proceeding within
the sixty-day period, it shall pay each dissenter whose demand remains unsettled
the amount demanded.

     2.   The corporation shall commence the proceeding in the district court of
the country where a corporation's principal office or, if none in this state,
its registered office is located. If the corporation is a foreign corporation
without a registered office in this state, it shall commence the proceeding in
the country in this state where the registered office of the domestic
corporation merged with or whose shares were acquired by the foreign corporation
was located.

     3.   The corporation shall make all dissenters, whether or not residents of
this state, whose demands remain unsettled parties to the proceeding as in an
action against their shares and all parties must be served with a copy of the
petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

     4.   The jurisdiction of the court in which the proceeding is commenced
under subsection 2 is plenary and exclusive. The court may appoint one or more
persons as appraisers to receive evidence and recommend decision on the question
of fair value. The appraisers have the powers described in the order
<PAGE>   122
appointing them, or in any amendment to it. The dissenters are entitled to the 
same discovery rights as parties in other civil proceedings.

     5.   Each dissenter made a party to the proceeding is entitled to judgment
for either of the following:

          a.   The amount, if any, by which the court finds the fair value of
     the dissenter's shares, plus interest, exceeds the amount paid by the
     corporation.

          b.   The fair value, plus accrued interest, of the dissenter's
     after-acquired shares for which the corporation elected to withhold payment
     under section 490.1327.

     490.1331     COURT COSTS AND COUNSEL FEES.

     1.   The court in an appraisal proceeding commenced under section 490.1330
shall determine all costs of the proceeding, including the reasonable
compensation and expenses of appraisers appointed by the court. The court shall
assess the costs against the corporation, except that the court may assess costs
against all or some of the dissenters, in amounts the court finds equitable, to
the extent the court finds the dissenters acted arbitrarily, vexatiously, or not
in good faith in demanding payment under section 490.1328.

     2.   The court may also assess the fees and expenses of counsel and experts
for the respective parties, in amounts the court finds equitable, for either of
the following:

          a.   Against the corporation and in favor of any or all dissenters if
     the court finds the corporation did not substantially comply with the
     requirements of sections 490.1320 through 490.1328.

          b.   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

Coordinating Committee of the Board of Directors
ALLIED Life Financial Corporation
701 Fifth Avenue
Des Moines, Iowa 50391

Gentlemen:

Fox-Pitt, Kelton Inc. ("Fox-Pitt, Kelton") understands that ALLIED Life 
Financial Corporation ("ALLIED Life"), Nationwide Mutual Insurance Company 
("Nationwide") and Nationwide Life Acquisition Corporation, a wholly-owned 
subsidiary of Nationwide ("Sub") propose to enter into an Agreement and Plan of 
Merger dated June 3, 1998 (the "Merger Agreement"). Pursuant to the Merger 
Agreement and subject to certain exceptions set forth therein, Nationwide and 
Sub shall make a tender offer to purchase all outstanding shares of common 
stock, no par value, of ALLIED Life (the "ALLIED Life Common Stock"), pursuant 
to which Sub shall pay $30.00 per share in cash for each share accepted (the 
"Consideration"). The Merger Agreement further provides that following 
completion of the tender offer Sub will merge (the "Merger") into ALLIED Life 
and each outstanding share of ALLIED Life Common Stock will be converted into 
the right to receive the Consideration. The terms and conditions of the Merger 
are more fully set forth in the Merger Agreement.

You have asked for Fox-Pitt, Kelton's opinion as to whether the consideration 
is fair, from a financial point of view, to the holders (other than ALLIED 
Mutual) of ALLIED Life Common Stock. In arriving at the opinion set forth 
below, Fox-Pitt, Kelton has, among other things:

          (a) reviewed and analyzed certain publicly available financial
     statements for ALLIED Life and Nationwide and financial information made
     available to us by the management of ALLIED Life;

          (b) analyzed certain internal financial statements, including
     financial projections, and other financial and operating data prepared by
     the management of ALLIED Life;

          (c) discussed the past, present and future operations, financial
     condition and prospects of ALLIED Life with the senior management of ALLIED
     Life;

          (d) compared the financial performance and condition of ALLIED Life
     with that of certain other comparable publicly traded companies;

          (e) reviewed and discussed with the senior management of ALLIED Life
     the strategic objectives of the Merger and certain other benefits of the
     Merger;

          (f) reviewed the financial terms, to the extent publicly available, of
     certain merger and acquisition transactions comparable, in whole or in
     part, to the Merger;

          (g) reviewed the Merger Agreement dated June 3, 1998; and

          (h) performed such other analyses as we have deemed appropriate.

Fox-Pitt, Kelton has assumed and relied upon, without independent 
verification, the accuracy and completeness of all of the financial and other 
information it has reviewed for the purposes of providing this opinion, and we 
have not assumed any responsibility for independent verification of such 
information. Fox-Pitt, Kelton has not assumed any responsibility for 
independent valuation of the assets and liabilities of ALLIED Life. With 
respect to the financial projections, Fox-Pitt, Kelton has assumed that they 
have been reasonably prepared by the management of ALLIED Life on bases 
reflecting the best currently available estimates and judgment of the future 
financial performance of ALLIED Life. We express no view as to such projections 
or the assumptions on which they are based. Fox-Pitt, Kelton's opinion is based 
upon economic, market and other conditions as they exist and can be evaluated 
on June 2, 1998.

In connection with the preparation of this opinion, we were not authorized by 
the Coordinating Committee to solicit, not have we solicited, third party 
indications of interest for the acquisition of all or part of ALLIED Life. We 
understand that ALLIED Mutual owns a controlling interest in ALLIED Life.

In the normal course of its investment banking business, Fox-Pitt, Kelton is 
regularly engaged in the valuation of insurance company securities in 
connection with acquisitions, negotiated underwritings, secondary distributions 
of listed and unlisted securities, private placements and valuations for 
various other purposes. As specialists in the securities of insurance 
companies, Fox-Pitt, Kelton has experience in, and knowledge of, the valuation 
of such enterprises.

In the normal course of its business, Fox-Pitt, Kelton provides research 
coverage on ALLIED Life and may trade equity securities of ALLIED Life and 
Nationwide Financial Services, Inc. for its own account and for the accounts of 
customers and, accordingly, may at any time hold a long or short position in 
such securities. We have acted as financial advisor to ALLIED Life in 
connection with this Merger, have received a fee in connection with our 
engagement as financial advisor and will receive an additional fee upon 
rendering our opinion in connection with the Merger.

It is understood that this letter is for the information of the Coordinating 
Committee of the Board of Directors of ALLIED Life and may not be used for any 
other purpose without our prior written consent.

Based upon and subject to the foregoing, Fox-Pitt, Kelton is of the opinion on 
the date hereof that the Consideration is fair, from a financial point of view, 
to the holders (other than ALLIED Mutual) of ALLIED Life Common Stock.

Very truly yours,

/s/ FOX-PITT, KELTON INC.
